In a spinning machine such as a rough spinning machine or a spinning machine, the pitch of each weight and its arrangement pattern are set in order to downsize the machine base. Generally, in the roving machine, the bobbin wheels are arranged in two rows in a zigzag manner, and the produced full roving bobbins are arranged in a zigzag shape. Further, in the spinning machine, the full roving bobbins are suspended in a bobbin carrier, arranged in a row as spares for replacement, and carried in to the left and right sides of the spinning machine base. Therefore, the pitch of the full roving bobbins at the time of production on the roving frame side is different from the pitch of the full roving bobbins loaded on the spinning frame side.

Therefore, the full roving bobbins produced by arranging in two rows in a zigzag manner on the side of the roving frame are set to 1 at the pitch on the side of the spinning frame.
It is necessary to load the bobbin carriers into the spinning machine in a row and arrange the empty bobbins arranged in one row at the pitch of the spinning machine in a zigzag arrangement in two rows on the bobbin wheel of the roving machine. is there.

For example, in Japanese Unexamined Patent Publication No. 61-197376, the support members linked to the bobbin carrier are arranged in a zigzag shape on the side of the roving machine, and the bobbin hangers suspended on the respective supporting members are arranged on the side of the roving machine. A bobbin carrier is disclosed that is modified in a staggered manner so as to correspond to the bobbin wheel of. According to this bobbin carrier, the empty bobbins that have been collected in a line at the pitch on the spinning machine side are arranged on the roving machine side in a zigzag pattern corresponding to the arrangement of the bobbin wheels. Therefore, the empty roving bobbins arranged in a zigzag pattern and the full roving bobbins produced in the zigzag pattern are simply moved by exchanging them up and down while maintaining their arrangement patterns. Can be changed. On the way to the spinning machine, the supporting members are rearranged from the zigzag shape to the linear shape, so that the bobbins are aligned in a single row, and the bobbins are conveyed to the spinning machine side at the pitch of the preliminary roving bobbin on the spinning machine side.

Further, Japanese Patent Application Laid-Open No. 61-174432 has a plurality of forks for exchanging and holding the bobbins, and the forks are arranged in a zigzag pattern corresponding to the bobbin wheel for the roving machine. For a bobbin carrier standing by above the roving frame, there is disclosed a pipe changer that can be arranged in a line at a pitch on the spinning frame side corresponding to the bobbin hanger line and can be moved up and down between them. This pipe changer has two types of forks, one for full bobbin transfer and one for empty bobbin transfer,
The full bobbin and the empty bobbin are exchanged by simultaneously operating a plurality of forks. According to this pipe changer, the full bobbins produced by the roving machine and arranged in a zigzag manner are mounted on the bobbin carrier in a line at the spinning machine side pitch, and the empty bobbin of the bobbin carrier is roving the roving machine. The bobbin wheel can be attached in a staggered manner according to the arrangement pattern.

This bobbin carrier has a large number of joints so that the supporting members are arranged in a zigzag shape, and it is necessary to provide a traveling roller for each joint, so that the number of rollers and bearings for that purpose increases. There was a problem.

Further, according to the pipe changer disclosed in Japanese Patent Laid-Open No. 61-174432, a plurality of grooved cams fitted to the spline shaft and rotated in order to change the fork interval according to the bobbin pitch. A gap changing device including a plurality of parts such as a cam follower that can slide the fork guided by the guide groove of the groove cam is required, and the structure of the pipe changer becomes complicated. In particular, as in this pipe changer, in a configuration in which the fork is actuated by combining the up-and-down displacement by the up-and-down mechanism and the horizontal displacement by the interval changing device, the mechanism becomes considerably complicated. Therefore, the equipment cost increases as the number of parts of the pipe replacement machine increases, and the failure rate increases due to the complicated structure, which may increase the frequency of pipe replacement errors. There was a problem.

The present invention has been made to solve the above problems, and an object thereof is to install bobbin hangers independently on the roving frame side and the spinning frame side and to run on the respective bobbin hangers.

With the above construction, according to the invention of claim 1, the bobbin conveyors hang a plurality of bobbins on bobbin hangers having different suspending pitches at positions where the respective conveyor rails are close to each other, and the bobbins are moved in opposite directions. proceed. Each bobbin carrier is stopped in a state in which both of the bobbins to be replaced on the leading side are located directly above the locking means arranged at the respective extraction positions.
From this state, the bobbin withdrawing process is performed, the locking means is moved up and down by one, and the bobbin is taken out by the locking means fitted to the bottom of the bobbin when the bobbin is raised. Then, the next transfer process is performed. That is, each bobbin carrier is advanced in the respective advancing directions so as to arrange the next replacement bobbin at the removal position, and the locking means for fitting the bobbin to be replaced is provided on the other side of the replacement. After the bobbin is pulled out, the empty bobbin hanger is moved toward the insertion position corresponding to the position immediately below the moving destination after the advance. Therefore, both bobbins to be exchanged are transferred to the lower side of the bobbin carrier of the other party to be exchanged, and the empty bobbin hanger after the bobbin of the other party to be exchanged is located directly above it. From this state, the bobbin insertion process is performed, the locking means is moved up and down by one, and the bobbins fitted to the locking means at the time of the ascent are inserted into the bobbin hangers arranged immediately above. Thus, the first bobbin exchange is completed. Then, by repeating the cycle of the bobbin removing process, the transferring process and the bobbin inserting process described above,
Both bobbins are exchanged by a predetermined number between both bobbin transporters while the bobbin transporters travel intermittently in their respective traveling directions.

According to the second aspect of the present invention, the locking means which can be fitted to the bobbins provided corresponding to both bobbins to be replaced are the bobbins to be replaced by the drive of the elevating and lowering drive means. The bobbin carrier is advanced by a pitch corresponding to the number of replacements so that each bobbin carrier is positioned immediately above the extraction position in the advancing direction of each bobbin carrier in the respective advancing direction. At this time, the bobbin on the other side of replacement is lifted and lowered at an insertion position corresponding to a position immediately below the destination position of the empty bobbin hanger after the bobbin is pulled out.
The ascending / descending stroke should be exchanged with a lowering position where the top of the bobbin fitted to the locking means is separated below the bobbin hanger and the locking means cannot engage with the hanging bobbin from each bobbin carrier. It corresponds to the distance between the bobbin and the raised position where it can be attached to and detached from the bobbin hanger. Therefore, each locking means corresponding to both bobbins to be replaced can be pulled up and down once at each withdrawal position to remove the bobbin to be exchanged, and lifted and lowered once at each insertion position. By doing so, the bobbin to be replaced can be inserted into the bobbin hanger. Further, each locking means can be moved on the path connecting the extraction position and the insertion position by driving the movement driving means. Therefore, both bobbins taken out from the bobbin hanger and fitted in the respective locking means are conveyed from their respective take-out positions to the inserting positions.

According to the third aspect of the present invention, on the outer peripheral surface of the endless encircling member mounted on the pair of pulleys arranged at a distance longer than the distance between the extracting position and the inserting position. Of the at least three locking means provided on the two, two locking means are arranged at the extraction position and the insertion position, respectively. From the state in which the bobbin is fitted only to the locking means on the insertion position side, the elevating drive means is driven to raise and lower each locking means once, whereby the bobbin is fitted on the locking means on the insertion position side. It is possible to insert the bobbin that has been used into the empty bobbin hanger immediately above and to remove the bobbin to be replaced next by the locking means on the extraction position side. That is, the bobbin can be inserted and removed and the next replacement bobbin can be removed at the same time by one vertical movement. Further, by driving the movement drive device to rotate the orbiting member so that the bobbin fitted in the locking means on the extraction position side is transferred to the insertion position, it is fitted on the locking means on the extraction position side. It is possible to dispose the bobbin at the insertion position and additionally dispose the locking means disposed on the lower surface side of the orbiting member at the extraction position.

According to the fourth aspect of the present invention, the plurality of locking means for transferring the full bobbin move on a path that is inclined substantially evenly about a line orthogonal to the traveling path of each bobbin carrier. To do. Therefore, since a large angle is formed between the moving path of the full bobbin and the traveling path of each bobbin carrier,
In the process in which the full bobbin to be replaced exits from the full bobbin row suspended on the bobbin carrier on the roving frame side and enters next to the replaced full bobbin row suspended on the bobbin carrier on the spinning frame side. It becomes easy to avoid engagement between the full bobbin to be replaced and another full bobbin.

According to the fifth aspect of the invention, the transfer device, the movement drive means, and the elevation drive means are drive-controlled by the control means. Each bobbin carrier receives propulsive force from the transfer device and enters the bobbin exchange device, and the transfer device is stopped and driven so that the bobbin to be replaced on the leading side is located immediately above each withdrawal position. Both bobbins are in a state of being located directly above the respective locking means arranged in their respective withdrawal positions. Next, the elevating and lowering drive means is driven, and each locking means is moved up and down once, so that the bobbins to be replaced arranged directly above are fitted into the locking means and pulled out from the bobbin hanger. When this lifting and lowering is completed and the locking means is again placed in the lowered position, the movement driving means and the transfer device are respectively driven, and the locking means for fitting both bobbins to be replaced are moved from their respective withdrawal positions. While moving toward the insertion position, the bobbin carriers move in opposite directions in their respective traveling directions so that the next replacement bobbin is arranged immediately above the removal position. The bobbins to be replaced fitted in the respective locking means are arranged in the respective insertion positions, and the next replacement bobbins are arranged in the respective withdrawal positions so that the empty bobbin hangers after the withdrawal of the bobbin on the other side of the exchange are formed. When it is arranged immediately above the insertion position, the elevating drive means is driven. Each locking means is moved up and down once at each insertion position, and both bobbins to be exchanged at the time of the elevation are inserted into the empty bobbin hangers to which the bobbins of the exchange counterparts have been attached. In this way, the first bobbin exchange cycle is completed. Similarly, the transfer device, the movement drive means and the elevating and lowering drive means are controlled by the control means so that the cycle from the driving of the elevating and lowering drive means in the state in which the locking means is arranged at the extraction position in the above control is repeated. Drive controlled. As a result, each bobbin carrier is intermittently advanced in the respective traveling directions in opposite directions, and both bobbins are exchanged by a predetermined number.

According to the sixth aspect of the present invention, at the lowered position of the locking means by the ascending / descending movement at the extraction position and the insertion position, the top of the bobbin pulled out and fitted into the locking means serves as the bobbin hanger. It is located between the bobbin carrier and the lower end of the hanging bobbin. After the locking means is moved up and down once at the extracting position, the movement driving means and the transfer device are driven and controlled by the control means, and the bobbin fitted in the locking means and the bobbin suspended from the bobbin carrier are separated. The positions of the locking means and the bobbin carrier are controlled so as not to engage with each other. Therefore, the engagement such as the collision of the bobbin does not occur even when the bobbin is not pulled out to a position where the top of the bobbin is below the lower end of the hanging bobbin when the bobbin is pulled out.

According to the seventh aspect of the invention, in the transfer process of transferring the bobbin to be replaced from the withdrawal position to the insertion position, the movement driving means and the transfer device are simultaneously started by the control means, and are simultaneously driven. The speed is controlled to stop. At this time, in the process of pulling out the bobbin to be replaced from the hanging bobbin row, the locking means controls the speed of the bobbin carrier at high speed, so that the bobbin fitted in the locking means moves to the bobbin carrier. Quickly pull out from the hanging bobbin row that was suspended and started moving at a low speed. Further, in the process in which the bobbin to be replaced enters the suspended bobbin row on the transfer destination side, the locking means controls the speed at a low speed and the bobbin carrier speed is controlled at a high speed. The bobbin to be replaced slowly enters the hanging bobbin row that moves at high speed. Therefore, the engagement between the bobbin to be replaced and the hanging bobbin is avoided.

It is designed to change to the specified direction at the branch point.

Next, the operation of the bobbin exchanging device 7 configured as described above will be described. Each roving machine 1 in the roving machine train F
During operation, the bobbin carriers 8 of the two empty bobbins EB arranged in a row above the respective machine stands are connected to the respective branch carrier rails 3.
Waiting on a, 3b. Further, during operation of each spinning machine 2 in the spinning machine row R, four bobbin carriers 9 in which a full spare bobbin FB for replacement spare is lined up in a suspended state on the left and right sides of each machine stand are each preliminarily transferred. Standing on the rails 4a, 4a. In this standby state, the transfer device 14 provided on the branch transport rails 3a and 3b and the preliminary transport rail 4a is in a state of being stop-controlled by the control panel CP.

In the row of roving frames F, when the roving frame 1 is full, the front side of the roving frame 1 in which the pipe changer is full runs intermittently along the longitudinal direction of the machine base, and on the bobbin wheel. Full bobbins FB arranged in a zigzag in two rows and stand by on branch conveyor rails 3a, 3b installed above the roving frame 2
A plurality of empty bobbins EB suspended by the bobbin carrier 8 of the machine are replaced. The two bobbin carriers 8 stand by in two rows in a state where the bobbin hangers 10 arranged in a row are arranged in a zigzag pattern corresponding to the arrangement of the bobbin wheels. Full bobbin FB
Each of the rows is mounted on two bobbin carriers 8. In addition, when equipped with a simultaneous pipe changer, two full rows of front and rear bobbins FB and 2 on the bobbin wheel are used.
The empty bobbins EB on which the bobbin carrier 9 of the machine hangs are simultaneously replaced. When the doffing work by the pipe changer or the simultaneous pipe changer is completed, the stop control of the transfer device 14 provided on the branch transfer rails 3a and 3b is released, and the full bobbin F
The two bobbin carriers 8 suspending B move toward the bobbin exchanging device 7 from the standby position so as to circulate on the carrier rail 3 in the clockwise direction in FIG.

On the other hand, in the spinning machine train R, a spinning machine 2
When the roving bobbin hung on the creel of the machine approaches the sky, a pair of roving changers travel to the machine base and intermittently run along the machine longitudinal direction on both sides of the machine base, approaching the sky. A plurality of empty bobbins EB and full bobbins FB suspended from the four bobbin carriers 9 waiting on the auxiliary carrier rails 4a and 4a are exchanged.

Then, when the roving exchange operation by the roving changer is completed, the stop control of the transfer device 14 provided on the preliminary transport rail 4a is released, and the empty bobbin EB is suspended 4
The bobbin carrier 9 of the machine is sequentially equipped with the preliminary carrier rails 4a, 4
Move from a to the loop path on the transport rail 4 adjacent to the spinning machine row R. Then, it circulates in the clockwise direction in FIG. 17 on this loop path, the ARS device 5 removes the residual roving yarn during the revolution, and the cutter device 6 cuts and removes the residual roving yarn that cannot be completely removed. . In this way, the bobbin carrier 9 that suspends the empty bobbin EB from which the residual roving has been completely removed is carried into the bobbin exchanging device 7.

Here, the driving force of the bobbin carriers 8, 9 traveling on the respective carrier rails 3, 4 is shorter than the total length of the bobbin carriers 8, 9 on the respective carrier rails 3, 4 on which they travel. It is provided from transfer devices 14 and 14a provided at intervals.

The bobbin carriers 8 and 9 in the standby state by the stop control by the control panel CP are in a state in which a part of the link member 12 is clamped and held by the rollers 21 and 22 of the transfer device 14 and the belt 20. When the stop control is released and the motor 28 is driven, a transmission force is applied to the link member 12 from the belt 20 that is rotationally driven by the drive via the contact surface with the belt 20. This transmission force serves as a propulsive force for traveling the bobbin carriers 8 and 9. The link member 12 connects the pulleys 18, 19 to the belt 20 that transmits the driving force.
The contact area is sufficiently secured by making contact with a wide surface over a length substantially equal to the distance between the axes. Therefore, even if a large number of bobbins FB and EB are suspended and relatively loaded, slippage does not occur between the link member 12 and the belt 20, and the rotational force of the belt 20 propels the link member 12. Reliably transmitted as force. Therefore, the bobbin carriers 8, 9
Starts running smoothly.

Before the rear ends (ends on the side of the roving frame) of the bobbin carriers 8 and 9 are released from the engagement with the transfer device 14, the forward ends of the bobbin carriers 8 and 9 in the traveling direction are moved to the next position. The device 14 is reached. In the state before the bobbins 8 and 9 arrive, the rollers 21 and 22 of the transfer devices 14 and 14a are urged toward the belt 20 by the elastic force of the spring 38 as shown in FIGS. Against the link member 12
Are held in a state of facing each other with a gap slightly shorter than the width. In this state, the proximity sensors 40 and 41 make the arm 3
The rear end faces 2b and 33b are detected and turned off, and the motor 28 is stopped.

For example, when the bobbin conveyors 8 and 9 move from the left direction in FIGS. 10 to 12, the tip of the link member 12 causes the gap between the belt 20 and the rollers 21 and 22 to act on the spring 38. Inversely, the rollers 21 and 22 are sequentially pushed in and pushed in. At this time, the roller 21 is pushed away first, and the arm lever 32 first rotates to turn on the proximity sensor 40 first, so that the motor 28 is driven in the normal direction and the pulley 19 rotates in the direction of arrow A in FIG. To do. Therefore, the belt 20 rotates in the clockwise direction in the drawing, and the propulsive force in the traveling direction is applied to the link member 12.

When the bobbin conveyors 8 and 9 move from the right direction in FIGS. 10 to 12, the tip of the link member 12 causes the spring 38 to urge the gap between the belt 20 and the rollers 21 and 22. Against each other, the rollers 22 and 21 are sequentially pushed in and invaded. At this time, the roller 22 is pushed away first, and the arm lever 33 first rotates to turn on the proximity sensor 41 first, so that the motor 28 is driven in reverse and the pulley 19 rotates in the direction of arrow B in FIG. . Therefore, the belt 20 rotates in the counterclockwise direction in the figure, and the propulsive force in the traveling direction is applied to the link member 12.

At this time, even when the bobbin conveyors 8 and 9 are running, a wide contact area is secured between the link member 12 and the belt 20 because the driving side that transmits the propulsion force is the belt 20. No slippage occurs between the link member 12 and the rotational force of the belt 20 is reliably transmitted to the link member 12 as its propulsion force.

Each bobbin carrier 8 and 9 receives the propulsive force from the transfer devices 14 and 14a provided on each path and advances to the bobbin exchanging device 7, and the bobbin exchanging device 7 is passed through the bobbin exchanging device 7 on the opposite side. It is brought in from. That is, the bobbin carrier 8 that suspends the full bobbin FB is carried in on the carrier rail 3 from the left side in FIGS. 1 and 17, and the bobbin carrier 9 that suspends the empty bobbin EB is carried in from the right side in FIG. To be done. At this time, each slide base device 52 of the bobbin changing device 7
˜55 are in the original position shown in FIG. 1 in which the peg 56 is placed in the extraction position, and the table 44 is in the lowered position.

The bobbin carriers 8 and 9 are carried into the bobbin exchanging device 7 by receiving a propulsive force from a transfer device 14a provided before and after the bobbin exchanging device 7. The motor 28 of the transfer device 14a is drive-controlled by the control device C, and during the drive, the deceleration control is performed based on the first ON signal of the proximity sensors 67 and 68, and the stop control is performed based on the second ON signal.

Therefore, the bobbin transfer body 8 that has entered the bobbin changing device 7 from the left side of FIG. 2 decelerates when the proximity sensor 67 detects a dog at its tip, and then the frontmost bobbin hanger 10 is detected. And stop. As a result, the top two full bobbins FB suspended from the bobbin carrier 8 are moved to the slide base device 5 as shown in FIG.
It is arranged directly above the peg 56 arranged at the original position of 2,53.

On the other hand, the bobbin carrier 9, which has entered the bobbin exchanging device 7 from the right side of FIG. And stop. As a result, the two leading empty bobbins EB suspended from the bobbin carrier 9 are moved to the slide base devices 54, 5 as shown in FIG.
5 is arranged directly above the peg 56 arranged at the original position.

Two full bobbins F to be replaced in this way
B and the empty bobbin EB are the slide base devices 52 to 55.
When it is recognized by the two ON signals of the proximity sensors 67 and 68 that the placement is completed just above the peg 56 placed in the original position of the, the lifting motor 47 is controlled by the controller C to a predetermined value. Forward / reverse rotation is performed only once in the rotation angle range. The gear 4 is driven by the forward / reverse driving of the lifting motor 47.
The drum 49 reciprocally rotates at a rotational speed decelerated via 9, 50, and the metal belt 51 is wound and unwound so that the table 44 is lowered to the lower position shown in FIGS. It is reciprocated once between the lifted position shown.

At this time, when the table 44 is raised, the pegs 56 arranged at the withdrawal positions (original positions) of the slide base devices 52 to 55 arranged on the table 44 are located below the full bobbin FB and the empty bobbin EB. The full bobbin FB and the empty bobbin EB are slightly pushed up by the pegs 56 and the engagement with the bobbin hangers 10 is released. Therefore, when the table 44 descends, the full bobbin F
B and the empty bobbin EB are pulled out to the lowered position while being fitted to the peg 56, and are arranged at the positions shown by the chain line in FIGS. 2 and 3.

In this ascending / descending process, the proximity sensor 69 on the extraction position (original position) side is activated, and the proximity sensor 69 is turned on at the raised position to confirm the existence of the suspended bobbins FB and EB to be replaced. If the bobbin FB and EB are continuously turned on at the lowered position, it is confirmed that the bobbins FB and EB have been pulled out without failure. All proximity sensors 69 in the raised position
The bobbins FB and EB to be replaced when the power is off.
When it is determined that the bobbin carriers 8 and 9 are not moved, the transfer device 14a is driven to move the bobbin carriers 8 and 9 by two pitches of the bobbin hangers 10. Further, when one of the proximity sensors 69 is in the off state at the raised position, or when any of the proximity sensors 69 is once turned on at the raised position but is turned off at the lowered position, the bobbin exchanging device is operated. 7 and the transfer device 14a are emergency stopped and an alarm is issued.

The respective motors 63 arranged in the
B and the empty bobbin EB are transferred from the extraction position to the insertion position. In this transfer process, the transfer device 14a is operated in parallel.
The motor 28 is driven and controlled.

The drive control of this transfer process will be described below with reference to FIG. The brake 63a is omitted in FIG. When the full bobbin FB and the empty bobbin EB are completely extracted as shown in FIG.
When 9 is in the ON state, each motor 63 is driven and each base plate 57 that erects the pegs 56 starts moving in the arrow direction in the figure from the extraction position toward the insertion position. for that reason,
The full bobbin FB is transferred from the carrier rail 3 side to the carrier rail 4 side, and the empty bobbin EB is transferred from the carrier rail 4 side to the carrier rail 3 side. At this time, the position sensor 65 (shown in FIG. 1) is activated.

The motor 63 is immediately stopped when the position sensor 65 is turned on by detecting the dog 57a while each base plate 57 is moving toward its insertion position.
FIG. 16 shows that 7 is located between the extraction position and the insertion position.
The vehicle is stopped at the intermediate stop position shown in (b). for that reason,
The full bobbin FB and the empty bobbin EB are provided on the respective transport rails 3 and 4.

When the position sensor 65 is turned on, the motor 28 of the transfer device 14a is driven to drive the bobbin transfer bodies 8 and 9.
Starts moving in the direction of the arrow in FIG. After the start of the movement, when the proximity sensors 67 and 68 in the off state detect the bobbin hanger 10 passing the first time and are turned on, the motor 28 is decelerated and the traveling speed of the bobbin transport bodies 8 and 9 is decelerated. . When the next bobbin hanger 10 is detected and the proximity sensors 67 and 68 are turned on again, the motor 2
16 (c) in which the driving of the bobbins 8 and 9 has been stopped and the bobbin carriers 8 and 9 have advanced by two pitches of the respective bobbin hangers 10.
It is stopped in the state shown in. That is, the bobbin hangers 10 after the full bobbins FB and the empty bobbins EB to be replaced have been removed from each base plate 57 as shown in FIG. 16C.
Is placed directly above the extraction position, which is the destination of the movement.

When the proximity sensors 67 and 68 are turned on twice, the motor 63 is driven again, and each base plate 57 starts moving in the arrow direction of FIG. 16C from the intermediate stop position toward the insertion position. At this time, the position sensor 66 (shown in FIG. 1) is activated.

When each position sensor 66 is turned on by detecting the dog 57a of each base plate 57, the corresponding motor 63 is immediately stopped and each base plate 57 is stopped at the insertion position. Therefore, the full bobbin FB and the empty bobbin EB are arranged at their respective insertion positions, the bobbin hanger 10 after the empty bobbin EB is removed is arranged directly above the full bobbin FB, and the full bobbin OB is immediately above the empty bobbin EB. The bobbin hanger 10 is placed after the FB is pulled out.

When the position sensors 66 (shown in FIG. 1) are all turned on in this way and it is confirmed that the full bobbin FB and the empty bobbin EB have been transferred to their respective insertion positions, the lifting motor 47 is driven, The table 44 is reciprocated once between the lowered position and the raised position.

At this time, when the table 44 is placed in the raised position, the full bobbin FB and the empty bobbin EB which are fitted in the pegs 56 of the slide base devices 52 to 55 and are placed in the loading position are the top parts. Are inserted into the bobbin hangers 10 located immediately above the respective bobbin hangers 10 and hooked on the respective bobbin hangers 10. Therefore, when the table 44 is lowered, the peg 56 is disengaged from the full bobbin FB and the empty bobbin EB, and only the peg 56 is lowered to the lowered position.

In this ascending / descending process, if the proximity sensor 70 on the insertion position side is operated and turned off at the descending position after one ascending / descending, it is confirmed that the bobbins FB and EB have been inserted without failure. To be done. At that time, in the lowered position, the proximity sensor 7
If either 0 is on, it is recognized that the bobbin FB, EB has been inserted incorrectly, and the bobbin exchanging device 7 and the transfer device 14a are emergency stopped and an alarm is issued.

When all the proximity sensors 70 are off at the lowered position, the motors 63 of the slide base devices 52 to 55 are driven to move the base plates 57 from the insertion position to the original extraction position. It is rebound toward. At this time, the position sensor 64 is activated and the dogs 57 of the base plates 57 are
Immediately after a is detected by the position sensor 64, the motor 63 is stopped and the base plate 57 is stopped at the original position where the peg 56 is arranged immediately below the transport rails 3 and 4. Thus, the bobbin changing device 7 and the transfer device 14 by the control device C
When the operation of 1 cycle of a is completed, the two full bobbins FB on the bobbin carrier 8 side and the two empty bobbins EB on the bobbin carrier 9 side are suspended from the bobbins FB, EB on the other side. The bobbin hangers 10 are mounted on the bobbin hanger 10, and the bobbin hangers 10 are exchanged with each other at intervals corresponding to the pitch of the exchange destination.

In the state where one cycle is completed, the full bobbin FB and the empty bobbin EB to be replaced next are arranged at the positions directly above the pegs 56 arranged at the original position. When the first one cycle is completed, the control device C starts the next one cycle from the ascending / descending operation of the table 44 at the original position. Thereafter, by repeating the cycle operation continuously, two full bobbins FB and two empty bobbins EB are exchanged between the bobbin carriers 8 and 9 having different pitches. Then, in the cycle of exchanging the last two bobbins FB and EB, the proximity sensors 67 and 68 detect the dog at the rear end so that the bobbin hanger 10 is arranged immediately above the insertion position. , 9 are stopped.

Both bobbin carriers 8 and 9 carry 60 bobbins B at a time, and bobbin replacement is performed by bobbin carriers 8 and 9.
Both of the bobbins FB and E are suspended from the bobbin carriers 8 and 9 of the same machine.
B is not separately installed on the bobbin carriers 8 and 9 of the partner machine. Therefore, even if the bobbin carriers 8 and 9 that handle different types are co-located on the transport rails 3 and 4, the bobbin F of different types can be mounted on one bobbin carrier 8 and 9.
B and EB do not mix.

The bobbin carrier 8 for suspending the empty bobbin B carried out from the bobbin exchanging device 7 circulates on the carrier rail 3 so that the branch carrier rail 3 corresponding to the original roving machine 1 is rotated.
An empty bobbin EB for replacement is supplied to the roving machine 1 after being carried into the a and 3b.

On the other hand, the bobbin carrier 9 carried out from the bobbin exchanging device 7 and suspending the full bobbin B temporarily waits in the pool line section 4c as needed, and can respond to the supply request of the full bobbin FB on an ad-hoc basis. Is stored in the pool line section 4c. Then, when the empty bobbin EB after the roving exchange is carried out and there is the spinning machine 2 waiting for the loading of the full bobbin FB, the bobbin carrier 9 waiting in the pool line part 4c moves the spinning bobbin 9 on the carrying rail 4 to the spinning machine. The vehicle travels toward 2, and is carried into the preliminary transport rails 4a on the left and right sides of the machine base.

Full bobbin B produced by the roving machine 1 in this way
Is transported to the side of the spinning frame R, and the empty bobbin EB used in the spinning frame 2 is transported to the side of the roving frame F. As described in detail above, according to the bobbin changing device 7 of the present embodiment, the roving machine row F
Bobbin carriers 8 and 9 for transporting bobbins FB and EB at different pitches on the respective spinning trains F and R on different transport rails 3 and 4 which are independently installed on the side of the spinning machine and on the side of the spinning machine train R.
Between the two bobbins FB and EB can be continuously exchanged.

Further, according to the bobbin changing device 7, since the bobbin is changed only by two linear movements of the peg 56, that is, the horizontal linear movement and the vertical movement, the slide base device for moving the peg 56 in the horizontal linear movement. 52-55
In addition, only the lifting mechanism of the table 44 for moving the peg 56 up and down is required, and the structure of the bobbin changing device 7 can be simplified.

Further, by only providing the bobbin exchanging device 7 having such a simple structure, the zigzag refracting movement disclosed in Japanese Patent Laid-Open No. 61-197376 is possible, and the rough spinning machine row side and the spinning machine row side are arranged. Even if the bobbin carrier whose pitch can be changed is not used, it is possible to doff the full bobbins FB in a zigzag in two rows without changing the arrangement while maintaining the arrangement state. Therefore, as in the above-mentioned respective embodiments, if two full-row bobbins FB are staggered on each of the two bobbin transport bodies 8 one row at a time, a simple doffing operation is sufficient. It is not necessary to have a complicated structure like the one disclosed in JP 61-174432. Furthermore, since the link member 12 of the bobbin carrier 8 is also linear along the carrier rail 3, the transfer devices 14 and 14a can be used, and the bobbin carrier 8 can be transferred in a relay manner by the transfer devices 14 and 14a. You can Further, the number of traveling rollers and bearings provided is smaller than that of the bobbin carrier disclosed in Japanese Patent Laid-Open No. 61-197376, which is mentioned in the prior art, and the manufacturing cost of the bobbin carriers 8, 9 is low. Can be suppressed to

In addition, the arrangement pattern of the slide base devices 52 to 55 has an inclination angle such that the side on which the full bobbin FB is transferred is line-symmetric with respect to the line orthogonal to the longitudinal direction of the transport rails 3, 4. It was placed on the table 44. Therefore, in the transfer process of moving the peg 56 into which the full bobbin FB is fitted from the extraction position to the insertion position, the adjacent full bobbins FB that are simultaneously transferred contact each other or the full bobbin FB that is transferred is bobbin-conveyed. It is possible to easily avoid contact with other bobbins FB and EB during the process of getting out of or entering the bobbin row suspended from the bodies 8 and 9.

Further, the full bobbin FB after withdrawal moves to an intermediate stop position where it can avoid contact with the hanging bobbins FB and EB in advance before the bobbin carriers 8 and 9 are started to travel. Then, after the bobbin carriers 8 and 9 have completed their progress, they are moved from the intermediate stop position to the insertion position.
Therefore, the bobbins FB and EB are removed and the table 44
Even if the tops of the bobbins FB and EB are slightly separated from the bobbin hanger 10 in a state in which is placed in the lowered position, the contact between the bobbins FB and EB can be avoided. Therefore, the ascending / descending stroke of the peg 56 is set to a short distance such that the peg 56 does not contact the lower parts of the hanging bobbins FB and EB in the original position and the tops of the extracted bobbins FB and EB are spaced downward from the bobbin hanger 10. Since the lifting stroke can be set shorter, the lifting time of the peg 56 can be shortened and the bobbin replacement cycle can be shortened.

Further, since the bobbin carriers 8 and 9 are made to enter the bobbin exchanging device 7 in directions opposite to each other, the empty bobbin hanger 10 after the bobbins FB and EB are removed by the peg 56 is replaced with the bobbin FB on the other side. , EB, the bobbin FB to be replaced next when it is moved to the insertion position of EB,
EBs are placed in their respective withdrawal positions. Therefore, the bobbins 8 and 9 need only be advanced once per cycle, which can contribute to shortening the bobbin replacement cycle.

Further, in the transfer devices 14 and 14a, the driving side for transmitting power to the link member 12 is constituted by the belt 20, and the contact area with the link member 12 is ensured to be sufficiently wide. Sliding is unlikely to occur on the contact surface with the member 12, and the driving force of the belt 20 can be efficiently transmitted to the link member 12. Therefore, even if the driving force of the belt 20 is the same, a stronger propulsive force can be applied to the link member 12. Even if the number of bobbins to be conveyed by the bobbin carriers 8 and 9 is large at a time due to the increase in the number of spinning machines and roving machines, the bobbin carriers 8 and 9 are transferred by a strong propulsive force without slipping. be able to. In particular, a relatively large propulsive force is required when starting the bobbin carriers 8 and 9, but a strong propulsive force is applied, so that the bobbin carriers 8 and 9 can be smoothly started.

The bobbin F for the bobbin hanger 10
Peg 5 is used to remove and insert (insert) B and EB.
Since it is performed by fitting 6 onto the bottoms of the bobbins FB and EB, the gripping operation of the bobbins FB and EB becomes unnecessary,
The bobbins FB and EB can be gripped and lifted by the same single lifting operation. (Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIGS.

In this embodiment, the full bobbin FB and the empty bobbin EB are extracted from the bobbin hangers 10 of the bobbin carriers 8 and 9, and then the full bobbin FB and the empty bobbin EB are transferred from the extraction position to the insertion position. This is different from the first embodiment. In the first embodiment, the slide base device 5
2 to 55 and the transfer device 14a are individually driven according to a predetermined operation sequence, but in the present embodiment, the slide base devices 52 to 55 and the transfer device 14a are simultaneously driven in parallel. It is very different from the example.

FIG. 19 shows set speeds of the motors 63 of the slide base devices 52 to 55 which are drive-controlled by the controller C and the motor 28 of the transfer device 14a. The set speed shown in FIG. 19 is pre-programmed in the controller C, and the speed control of each motor 28, 63 is performed according to the speed chart of FIG. In FIG. 19, the solid line A is the set speed of the motor 63, and the broken line B is the motor 28.
Is the set speed.

The operation procedure of the transfer process will be described below with reference to FIG. FIG. 18A shows the frontmost two bobbins F.
Full bobbin B1 to be replaced next after B and EB are replaced
And the empty bobbin B2 are pulled out from the bobbin hangers 10 and are arranged at the respective withdrawn positions (original positions). The transfer process is started from this state.

First, as shown in FIG. 19, the motor 63 is driven at high speed (H) and the motor 28 is driven at low speed (L). However, the bobbin F
It goes through extremely low speed range LL so that B and EB do not shake. From the state of FIG. 18A, the base plate 57 and the bobbin carriers 8 and 9 start moving in the directions of the arrows.
Since the base plate 57 moves at high speed H and the bobbin carriers 8 and 9 move at low speed, the bobbins B1 and B on the base plate 57 are moved.
2 quickly withdraws from each bobbin row and the bobbin row moves slowly, so that the full bobbin B1 does not interfere with other full bobbins FB in the bobbin row.

As shown in FIG. 18B, the bobbins B1,
When B2 is completely pulled out from each bobbin row (for example, the intermediate stop position), the motor 63 is decelerated from the high speed range H to the low speed range L and the motor 28 is decelerated from the low speed range L to the high speed range H as shown in FIG. Be accelerated to. Therefore, FIG. 18 (c)
As shown in, when the full bobbin B1 is slowly placed in the insertion position, when the bobbin row on the transfer destination side slowly moves into the insertion position, the bobbin row on the transfer destination side moves quickly to open a space at the insertion position. , Full bobbin B1 is prevented from interfering with the replaced full bobbin FB. At this time, the empty bobbin B2 having a small outer diameter is, of course, arranged at the insertion position without interfering with the other bobbins FB and EB (FIG. 18).
(State of (c)). Immediately before the bobbins B1 and B2 are arranged at the insertion position, the motors 28 and 63 are decelerated to a very low speed range LL, and when the bobbins B1 and B2 are stopped at the insertion position, the bobbins B1 and B2 are stopped.
Does not swing and interfere with other bobbins FB and EB.

As described above, since the transfer operation of the base plate 57 and the transfer operation of the bobbin carriers 8 and 9 are simultaneously performed, the time required for the transfer process is short, and the time required for bobbin exchange is further increased. It can be shortened.

Further, in this transfer process, the base plate 57 is smoothly transferred from the extraction position to the insertion position without stopping midway. Further, the base plate 57 and the bobbin transporters 8 and 9 are started at the same time and stopped at the same time, and it looks like one operation, so that it looks good in operation.

The present invention is not limited to the above embodiments, but may be configured as follows, for example, within the scope of the invention. (1) As shown in FIG. 20, three pegs 74a, 74b, and 74c are provided on the outer peripheral surface of an endless belt 73 as a revolving member that is hooked on a pair of pulleys 71 and 72, and their intervals are at the extraction positions. Is fixed to the slide base of each of the above-described embodiments so that the belt 73 is rotated counterclockwise in the figure by driving the motor 75. It may be arranged on the table 44 which can be moved up and down in the same arrangement pattern as the apparatus. According to this structure, it is possible to complete the lifting and lowering operation of the peg, which has been performed twice in one cycle in each of the above-described embodiments, by pulling out and inserting (inserting), and it is necessary to return the peg 56. Disappears. That is, as shown by the chain line in the figure, the bobbin FB is arranged directly above the peg 74a on the extraction position (right side in the figure) side, and the bobbin FB is fitted on the peg 74b on the insertion position side (left side in the figure) side. At the same time, the table 44 is moved up and down by 1 from a state in which the empty bobbin hanger 10 is arranged immediately above. Then peg 7
The bobbin FB arranged immediately above 4a is a peg 74a.
The bobbin FB fitted on the peg 74b is fitted on the bobbin hanger 10. That is, the bobbin F on the sampling position side can be lifted by one lifting operation.
The removal of B and the insertion (insertion) of the bobbin FB at the insertion position side are performed simultaneously. Next, the motor 75 is driven to rotate the belt 73 counterclockwise by a predetermined amount. As a result, the bobbin FB fitted on the peg 74a is transferred from the extraction position to the insertion position, and the peg 74c on the lower surface side of the belt 73 is arranged at the extraction position. During this transfer process, the transfer device 14a is driven so that the bobbin transfer bodies 8 and 9 are moving in parallel, and the state shown by the chain line is first described. Similarly, a bobbin is continuously exchanged by a predetermined number by repeating a cycle in which the table 44 is moved up and down once and the belt 73 is rotated by a predetermined amount. Therefore, the bobbin replacement time can be significantly shortened as compared with the above-mentioned embodiments.

(2) The number of exchanges in one cycle can be appropriately changed. For example, two slide base devices may be arranged and replaced one by one, or six slide base devices may be arranged and replaced three by three.

(3) The trajectories of the transport rails at the bobbin exchange section are not limited to being parallel, and may be slightly expanded or curved as long as both bobbin transport bodies can move in opposite directions. Further, the heights of the transport rails may be different. In this case, the lifting stroke of the peg may be made different between the extraction position and the insertion position.

(4) The movement path of the peg 56 in the transfer process is not limited to a straight line and may be bent. For example, the peg 56 may be provided on the base plate 57 so as to be movable in the width direction of the housing case 58, and may be guided along a bent guide groove. With this structure, the structure is simple and the peg 56 can be moved on the bending path.

(5) The layout pattern of the slide base device should be appropriately changed according to the bobbin hanger pitches of both bobbin carriers, the bobbin diameters for exchange symmetry, and the locus route of the transport rails at the bobbin exchange site. You can

(6) Instead of the slide base device driven by the ball screw mechanism, a rodless cylinder (table cylinder) having a piston that moves in the cylinder by air pressure balance on both sides may be used. A magnet is provided on the piston of the rodless cylinder, and the peg may be magnetically attached to the magnet to move on the cylinder integrally with the piston. Since the rodless cylinder has a good airtightness, it is possible to avoid a decrease in mobility caused by the entry of cotton wool or the like. The peg may be linearly movable by an air cylinder with a rod. (7) The elevating mechanism of the table 44 is not limited to the belt type mechanism as in the above embodiments, but may be a rack and pinion mechanism or a ball screw mechanism. In particular, the rack and pinion mechanism is suitable because the power transmission capability does not deteriorate so much even if some fly dust enters the movable part. Further, the table 44 may be moved up and down using a cylinder.

(8) The peg 56 may be moved up and down without using the table 44. For example, the slide base device 5
A cylinder having a peg at the tip of the piston rod may be erected on the base plate 57 of 2 to 55.

(9) For example, as disclosed in Japanese Unexamined Patent Publication No. 63-29016, a combination with a transfer device for sandwiching a link member with a pair of rotating disks to apply a propulsive force to a bobbin carrier. Alternatively, the bobbin changing device 7 may be used.

(10) The lifting stroke of the peg 56 is set longer than the bobbin length, and the top of the bobbin fitted on the peg 56 is suspended from the bobbin carriers 8 and 9 by the bobbins FB and E.
The table 44 may be lowered to a position where it cannot contact the lower end of B. According to this configuration, since it is not necessary to consider the interference between the bobbins FB and EB and the hanging bobbins FB and EB that are transferred during the transfer process, although the lifting time is somewhat longer, the stop control of the pegs 56 during the transfer process is performed. (First embodiment)
Since there is no need to perform speed control (second embodiment),
The control system can be simplified.

(11) In the process of transferring the peg 56 and the process of moving the bobbin carriers 8 and 9, the peg 56 and the bobbin carriers 8 and 9 may be moved at a constant speed. The control system can be further simplified and the time required for each process can be shortened. In this case, the bobbins sway slightly when they come into contact with each other, but there is no problem as long as the bobbins FB and EB are not disturbed.

(12) Instead of using the transfer device, the bobbin carrier may be pulled by a carrier and carried into the bobbin exchanging device 7. The invention grasped from the above-mentioned embodiment and not described in the scope of claims is described below together with its effect.

(B) In any one of claims 1 to 7, the bobbin hanger pitch of the bobbin carrier that travels on the conveyor rails on the row side of the roving frame is one row of bobbin wheels arranged in two rows of the roving frame. The bobbin hanger pitch of the bobbin carrier which is set to be equal to the side pitch and which travels on the conveyor rail on the side of the spinning machine row is set to be equal to the arrangement pitch of the preliminary roving bobbins of the spinning machine. According to this configuration, when the full bobbins produced by the roving machine are arranged in two rows on the bobbin wheel in a zigzag manner, the arrangement of the bobbins on the bobbin carrier remains unchanged without changing the arrangement. It is only necessary to mount one row at a time, and the bobbin exchanging device moves the bobbin carrier that hangs a full bobbin on the carrier rail of the spinning machine from the bobbin carrier to the bobbin carrier of the spinning machine. The pitch of the roving bobbin can be replaced.

(B) In any one of claims 5 to 7, the transfer device sandwiches a movement path of a link member provided in series on the bobbin carrier so as to be capable of bending movement in the same plane. On both sides, there are provided a drive belt mounted on a pair of pulleys which are rotationally driven by the drive means, and a pressing means capable of gripping the link member while permitting movement of the link member between the drive belt. In preparation for the state of being opposed to each other, at least one of the drive belt and the pressing means is configured to be urged by the urging means so that the link member can be clamped and held between the both. According to this configuration, the link member is in contact with the drive belt on the outer peripheral surface over a length equal to the distance between the axes of the pair of pulleys that hangs the drive belt, and the contact area is sufficiently wide. From
Since the driving force from the driving belt is efficiently transmitted to the link member without slippage at the contact surface, the bobbin carrier can be reliably transferred.

(C) In claim 4, the lifting drive means includes a table on which the moving drive means for moving the locking means on the linear path is arranged, and a table lifting drive for moving the table up and down. And means. According to this configuration, it is not necessary to individually provide a driving means for moving the locking means up and down, and only one table lifting drive means can be used.

[0124]

As described above in detail, the first and second aspects are provided.
According to the invention described in claim 5, bobbins that are suspended by bobbin hangers having different suspension pitches can be exchanged between bobbin carriers that travel on different transport rails, and the locking means can be moved up and down. Since it is carried out by a combination of two types of simple movements, that is, a moving movement and a transfer movement, there is an excellent effect that the apparatus for carrying out the construction can have a simple structure.

According to the third aspect of the present invention, the bobbin is pulled out at the extraction position and the bobbin is inserted at the insertion position at the same time by raising and lowering the locking means once, and the locking is performed. With the means moved from the extraction position to the insertion position,
Since the locking means for pulling out the next bobbin is arranged at the pulling-out position, there is an excellent effect that the time required for one cycle of bobbin exchange can be considerably shortened. .

According to the invention described in claim 4, the moving paths of the plurality of locking means for transferring the full bobbin are set so as to be inclined substantially evenly around the line orthogonal to the moving path of each bobbin carrier. Since a large angle is formed between each bobbin carrier and the traveling path, it is possible to transfer the full bobbin to be replaced linearly without engaging with another full bobbin hanging from the bobbin carrier. It has an excellent effect that it can be done.

According to the sixth aspect of the present invention, when the bobbin carrier moves after the bobbin is removed, the bobbin to be replaced fitted in the locking means is engaged with the bobbin suspended from the bobbin carrier. The bobbin does not have to be pulled out to a position where the top of the bobbin is below the lower end of the hanging bobbin when it is pulled out, and the lifting stroke of the locking mechanism can be set smaller, improving the bobbin replacement speed. Can be made.

According to the invention described in claim 7, the linear movement of the locking means from the extraction position to the insertion position and the advance of the bobbin carrier are simultaneously started by the speed control and simultaneously stopped. Since the process is performed in a progressive manner, the operation is short and the appearance is good.
