And the cans C1 to C36 are the new cans in the standby state.

In the present invention, when the worker finds that any of the cans A1 to A36 and the cans B1 to B36 supplying the sliver to the spinning units S1 to S72 is almost empty, Operates a predetermined control device to run a sliver splicing device, which will be described below, along a conveyor rail arranged above the spinning machine Sp, and to move one of the new cans C1 to C36 in a standby state. The new sliver and old sliver of Kens are automatically inherited.

Further, an appropriate detector such as an optical sensor is arranged on each of the cans A1 to A36 and the cans B1 to B36 to automatically detect an empty can, and the sliver splicing device is driven to a predetermined position by the detection signal. It is also possible to perform sliver splicing.

Further, for example, the drive of the spinning machine Sp is controlled so that the cans A1 to A36 are almost simultaneously emptied, and the sliver splicing device is caused to run along the transport rail in the longitudinal direction of the spinning machine Sp to make empty cans. The old sliver of A1 to A36 and the new sliver of new cans C1 to C36 can be successively spliced in succession. For example, when the spinning machine Sp is started, the odd-numbered spinning units S1, S3, S5 ... And the even-numbered spinning units S2, S4, S6 ... ~ A36 and cans B1 to B36 can be made to be almost empty all together with a certain time difference.

The sliver splicing device of the present invention that can cope with various situations as described above will be described in detail below. FIG. 2 is a side view of the spinning machine Sp in which a sliver splicing device P described later is arranged. A1, B1 and C1 are cans arranged behind the spinning machine Sp. In FIG. 2, the cans A1 and B1 supply the slivers S2 and S3 to a predetermined spinning unit, and the cans C1. Is a new can in the standby state in which the end Se of the new sliver S1 is hanging from the mouth of the lens.

The sliver S2 and S3 are supplied to a predetermined spinning unit while being guided by appropriate sliver guide rollers G2 to G5.

D is a column for supporting a rail R on which the sliver connecting device P travels. The column D can be attached to the back of the spinning machine Sp, can be hung from the ceiling, and can be further hung from the floor. It can also be installed upright.

The rail R is arranged above the spinning machine Sp along the longitudinal direction of the spinning machine Sp so that the sliver splicing device P can travel along the rail R in the longitudinal direction of the spinning machine Sp. Has been done.

The sliver splicing device P includes a carriage F traveling on a rail R, a housing H attached to the lower part of the carriage F, an operation casing M vertically movably arranged in the housing H, and a horizontal direction. A horizontal frame E having one end for supporting the movable sliver gripping tool K attached to the housing H and a horizontal frame E for supporting the sliver gripping tool L movable in the vertical direction can be horizontally moved. It is composed of a vertical frame J supported by a sliver joint device and a positioning member N for accurately stopping the sliver splicing device P at a predetermined position.

The dolly F, the housing H, the operation casing M, the horizontal frame E, the vertical frame J, and the positioning member N, which constitute the sliver connecting device P, will be described below. The truck F has an axle 1 having wheels 2 rolling on a rail R attached at both ends, and the axle 1 and the wheels 2 are rotated by a suitable transmission device such as a motor and gears or belts not shown. As a result, the sliver splicing device P is moved above the spinning machine Sp along the longitudinal direction of the spinning machine Sp.

As shown in FIG. 2, the horizontal frame E extends in a direction perpendicular to the longitudinal direction of the spinning machine Sp so that the horizontal frame E extends from the rear surface of the spinning machine Sp over the new can C1 in the standby state. It is attached horizontally to the bottom of Usingu H.

A pulley 4 and a pulley 5 are installed at substantially both ends of the horizontal frame E, and an endless belt or an endless chain 3 (hereinafter, simply referred to as “endless belt”) is provided between the pulleys 4 and 5. ) Is stretched.

Further, as shown in FIG. 3, the sliver gripping tool K attached to the endless belt 3 includes a rotary solenoid 6 capable of forward and reverse rotation, and a sliver clamp 7 a rotated by the rotary solenoid 6. In the closed state, the sliver clamp 7a and the fixed sliver clamp 7b have fixed sliver clamps 7b, which extend toward the front in a direction substantially perpendicular to the paper surface of FIG. The sliver clamp 7a is appropriately rotated to the position of the chain double-dashed line shown in FIG.

The sliver clamp 7a and the fixed sliver clamp 7b are provided so as to be inclined so that the sliver in the horizontal position and the sliver in the vertical position can be grasped, and preferably the sliver can be grasped when it has an inclination of 45 °. Maximum range. That is, the sliver clamp 7a that can be rotated by the rotary solenoid 6 is preferably configured so as to be openable and closable along a plane at 45 ° with respect to the horizontal plane.

Further, the sliver gripping tool K can be horizontally moved along the horizontal frame E over substantially the entire length of the horizontal frame E by rotating the pulley 4 or the pulley 5 by a motor (not shown) capable of rotating in the forward and reverse directions. Is configured.

As shown in FIG. 2, a vertical frame J is horizontally slidably mounted on the horizontal frame E along the horizontal frame E by a suitable fitting means. The frame J is provided with a vertical rod 11 which is guided by, for example, a guide roller 10 and can be moved up and down by a known driving means (not shown).

A sliver gripping tool L is attached to the tip of the vertically movable vertical rod 11 as shown in FIGS. 4 and 5. A support frame 17 is attached to the end of the vertical rod 11 so as to be rotatable with respect to the vertical rod 11 by a shaft 17a, and a gear 13a and a gear 13b meshing with each other can be rotated on the support frame 17. Is installed in. Further, the end portion 17b opposite to the side where the gear 13a and the gear 13b are rotatably installed with respect to the shaft 17a of the support frame 17 has an end portion of a vertical rod 18 which can be moved up and down by an appropriate driving means. Has been attached.

Sliver clamps 12a and 12b are attached to the gears 13a and 13b, respectively, and a substantially L-shaped rotating frame 14 extends at the upper end of one of the sliver clamps 12a. The other end 14a of the rotary frame 14 of the sliver clamp 12a is in contact with the end 15c of the rotary rod 15 pivotally attached to the vertical rod 11 by a shaft 15a. On the other end 15b of the rotating rod 15, an end of a vertical rod 16 which is vertically movable by a suitable driving means is pivotally attached.

Therefore, when the upper and lower rods 18 are moved upward from the position shown by the solid line in FIG. 5 by an appropriate driving means, the support frame 17 is rotated around the shaft 17a in the clockwise direction in FIG. Then, it rotates to the position shown by the chain double-dashed line, and conversely, when the vertical rod 18 moves downward, it returns to the position shown by the solid line in FIG.

When the upper and lower rods 16 are moved upward from the positions indicated by the solid lines in FIG. 4 by an appropriate driving means, the rotating rod 15 is rotated about the shaft 15a in the counterclockwise direction in FIG. Then, the rotary frame 14 of the sliver clamp 12a, which is in contact with the end portion 15c of the rotary rod 15, is rotated around the shaft 19 of the gear 13a in the clockwise direction as shown by the chain double-dashed line in FIG. Rotate. The rotation of the rotating frame 14 of the sliver clamp 12a in the clockwise direction causes the gear 13a to rotate in the same direction, while the gear 13b meshing with the gear 13a rotates in the counterclockwise direction, so that the sliver clamp 12a and 12b open as shown in phantom in FIG. When the upper and lower rods 16 are moved downward from this state, the rotating rod 15 returns to the position shown by the solid line in FIG. 4, the sliver clamps 12a and 12b are returned to the position shown by the solid line, and the sliver clamps 12a and 12b are closed. .

Thus, the vertical movement of the vertical rod 16 opens and closes the sliver clamps 12a and 12b to grip and release the sliver S, and the vertical movement of the vertical rod 18 causes the sliver clamps 12a and 12b to move vertically. It is possible to rotate from to the inclined position.

As shown in FIG. 2, the sliver gripping tool K and the vertical frame J are connected by a suitable elastic member 20 such as a spring, and follow the lateral movement of the sliver gripping tool K. The vertical frame J is configured to be movable in the horizontal direction, and further, the elastic member 20 is not extended when the vertical frame J is moved in accordance with the movement of the sliver gripping tool K. Has been done.

Further, in FIG. 2, reference numeral 21 denotes a stopper provided on the horizontal frame E, which moves in the horizontal direction following the sliver gripping tool K when the sliver gripping tool K moves to the right. The vertical frame J comes into contact with the stopper 21 and acts to prevent further tracking of the vertical frame J to the right. Therefore, when the sliver gripping tool K moves further to the right after the vertical frame J contacts the stopper 21, the elastic member 20 expands.

FIGS. 6 and 7 (only the support J ′ of the vertical frame J is shown in FIG. 7) of the elastic member 20 for connecting the sliver gripping tool K and the vertical frame J described above. A more specific example is shown. Inside the supporting base J ′ of the vertical frame J and the supporting base K ′ of the sliver gripping tool K, as shown in FIG. 7, suitable guides are provided on the upper part of the horizontal frame E, respectively. Rails g1 to g3 (only the cross section of the guide rails g1 to g3 is shown in FIG. 7) and guide rollers r1 to r4 which can roll along the end of the horizontal frame E are provided. The support frame J ′ of the vertical frame J and the support frame K ′ of the sliver gripping tool K are guided by the guide rollers r1 to r4 to the guide rails g1 to g3 and the end of the horizontal frame E while being guided to the horizontal frame. It is configured to be able to move on E.

In this embodiment, the sliver gripping tool K and the vertical frame J are connected to each other by a support base K ′ of the sliver gripping tool K that can store the long leaf spring 20b in a retractable manner by the elastic force of the leaf spring 20b. The leaf spring storage case 20a attached to the upper part of the vertical frame J and the fixture 20c for fixing the end of the long leaf spring 20b attached to the upper part of the support J'of the vertical frame J. The support J'of the vertical frame J and the support K'of the sliver gripping tool K are shown in FIGS. 6 and 7 except that the vertical frame J contacts the stopper 21 and is prevented from moving to the right. As described above, the leaf springs 20b are always in contact with each other due to the elastic force, and the vertical frame J moves in accordance with the horizontal movement of the sliver gripping tool K.

The fixed sliver clamp 7b and the forward / reverse rotatable rotary solenoid 6 are attached to the lower protruding portion K1 of the support base K ′ of the sliver gripping tool K, and the forward / reverse rotatable rotary solenoid is attached. A sliver clamp 7a is attached to the unit 6.

As described above, the sliver clamp 7a that can be rotated by the rotary solenoid 6 can be opened and closed freely along the plane of 45 ° with respect to the horizontal plane as shown in FIGS. 3, 6 and 7. Rotate. The horizontal overhanging portion K2 of the sliver gripping tool K is attached to the endless belt 3 by an appropriate fixing member.

Therefore, for example, in FIG. 6, when the endless belt 3 rotates to the right, the sliver gripping tool K attached to the endless belt 3 moves to the right via the horizontal overhanging portion K2, and the sliver gripping is performed. The vertical frame J, which is connected to the tool K by the elastic member 20 including the leaf spring storage case 20a, the leaf spring 20b, and the fixing tool 20c, also follows the sliver holding tool K while being in contact therewith. Then, when the vertical frame J abuts on the stopper 21 installed on the horizontal frame E so that only the vertical frame J abuts, the vertical frame J 1 is prevented from moving to the right, and the long leaf spring 20b is moved. Only the sliver gripping tool K moves to the right while pulling out from the leaf spring storage case 20a. When the sliver gripping tool K is moved leftward from such a state, the sliver gripping tool K is prevented from moving to the right by the stopper 21 while the long leaf spring 20b is stored in the leaf spring storage case 20a. The vertical frame J is moved until it comes into contact with the stationary vertical frame J, and after contacting the vertical frame J, the vertical frame J is pushed to move leftward together with the vertical frame J.

Next, the housing H and the operation casing M arranged so as to be vertically movable in the housing H will be described in detail. First, FIG. 8 (a schematic front view of the housing H and the operation casing M). ) And FIG. 9 (left side view of FIG. 8), the outline of the housing H and the operation casing M 1 will be described.

Reference numerals 22 a and 22 b are guide rods installed between the upper plate 23 and the lower plate 24 of the housing H, and the guide rods 22 a and 22 b are cylindrical bodies 25 and 26 attached to the operation casing M. And guides an operating casing M 1 which is inserted into the housing and moves up and down with respect to the housing H.

Reference numeral 27 denotes a lever, one end of which is pivotally supported by a shaft 28 attached to the operation casing M, and the other end of which is attached to a rod 30 which is fixed to the upper plate of the housing H. A roller 29 is pivotally mounted on the motor 7, and the roller 29 is in contact with a control cam 31 having an appropriate contour. The motor 35 is mounted on the operation casing M via a chain 32, sprockets 33 and 34. Thus, the control cam 31 is rotationally driven.

With the above configuration, when the control cam 31 is rotated and, for example, the roller 29 comes into contact with the contour of the control cam 31 far from the rotation center 31a of the control cam 31, The shaft 28 is pushed upward, and therefore the operation casing M is moved upward along the guide rods 22a and 22b. On the contrary, when the roller 29 comes into contact with the contour of the control cam 31 close to the rotation center shaft 31a of the control cam 31, the shaft 28 is pushed downward, and therefore the operation casing M is guided by the guide rod 22. It will be moved downwards along a and 22b. By rotating the control cam 31 having an appropriate contour in this manner, the operation casing M is moved in the vertical direction.

27a, 27b ..., 30a, 30b ... And 31a, 31b ... are levers, rods, and control cams that operate in the same manner as the lever 27, rod 30, and control cam 31 described above. There are a lever, a rod and a control cam for controlling the movement of a sliver clamp or a piecing member for performing a sliver joint described later.

Next, based on FIGS. 10 and 11 which mainly show a perspective view of the operation casing M and an enlarged perspective view of the sliver splicing portion, a configuration and an operation thereof for performing the sliver splicing will be described. Reference numerals 37 and 38 denote an upper piecing member and a lower piecing member for kneading and joining the ends of the old sliver S2 and the ends of the new sliver S1 as described later. As shown in FIG. 9, the upper piecing member 37 is connected to a connecting rod 49 via a connecting member 48 such as a pin, and the connecting rod 49 is provided on the periphery of the rotary plate 47. Is pivotally supported on a shaft 50. The upper piecing member 37 and the connecting rod 49 are configured to be rotatable with respect to the connecting member 48.

Similarly, the lower piecing member 38 is also connected to the connecting rod 52 via a connecting member 51 such as a pin as shown in FIG. 9, and the connecting rod 52 is connected to the rotary plate 47. Is pivotally supported by a shaft 53 provided in the peripheral portion of the. The lower piecing member 38 and the connecting rod 52 are also configured to be rotatable with respect to the connecting member 51.

The shaft 50 and the shaft 53 for pivotally supporting the connecting rod 49 and the connecting rod 52 are attached to the peripheral portion of the rotating plate 47 with a phase difference of 180 degrees, and the rotating plate 47 is shown in the drawing. The upper piecing member 37 and the lower piecing member 38 are normally and reversely rotated so as to reciprocate left and right in FIG. The rotary plate 47 is for reciprocating the upper piecing member 37 and the lower piecing member 38 to the left and right with a predetermined width, and is not limited to such an embodiment. For example, two gears that mesh with each other may be arranged vertically, and the connecting rod 49 and the connecting rod 52 may be pivotally supported by the respective gears. In this case, the upper piecing member 37 and the lower piecing member 38 can be reciprocated simply by rotating the meshing gears in one direction.

When the sliver joint is not performed, one end of the upper piecing member 37 is attached to the rod 55 installed between the fixed frame 43 and the fixed frame 44, as shown in FIG. The other end of the upper piecing member 37 is rotated around the shaft 50 by the spring 54 attached to the back of the upper piecing member 37 and is on standby. Similarly, when the sliver joint is not performed, the lower piercing member 38 also pivots downward about the shaft 53 and stands by.

Reference numerals 45 and 46 respectively denote an upper pressing member and a lower pressing member that come into contact with the backs of the upper piecing member 37 and the lower piecing member 38, respectively. Wheels 56a to 56d and a wheel 58 are rotatably provided on the side in contact with the lower piecing member 38, respectively. The wheels 56a to 56d and the wheel 58 are provided so that the upper piecing member 37 and the lower piecing member 38 described above can be smoothly reciprocated in the left-right direction.

Further, as shown in FIG. 10, the upper pressing member 45 is attached to one end of a lever 57 that is rotatably supported by a shaft 55 and sandwiches the shaft 55. The other end of the lever 57 on the opposite side is connected to one of the above-mentioned rods 30a, 30b ..., For example, the rod 30c, and the rod 30c is connected to the levers 27a, 27b. The control cams 31a, 31b, etc., such as the lever 27c and the control cam, rotate in the vertical direction, so that the upper holding member 45 is placed in the upper standby position and the upper portion shown in FIG. The piecing member 37 is appropriately moved to either position from the operating position for holding the piecing member 37 from the rear side in a state of performing a kneading operation for splicing the sliver. Although not shown, the lower pressing member 46 is also attached to one end of a lever 59 that is rotatably supported by a shaft 60, and has a lower standby position and a lower piecing member 38. It is appropriately moved to either position from the operating position where it is pressed from the back to the state of performing a kneading operation for sliver splicing.

In FIGS. 10 and 11, 39 is an upper clamp for the new sliver, and 40 is a lower clamp 40 for the new sliver for gripping the new sliver S 1 in cooperation with the upper clamp 39 for the new sliver. Although not shown, the new sliver upper clamp 39 and the new sliver lower clamp 40 are levers 27a, 27b ..., Rods 30a, 30b ... And control cams 31a, 31b. Each of the driving means is configured to rotate in the vertical direction so that it can be opened and closed as needed.

Similarly, 41 is an upper clamp for the old sliver, and 42 is a lower clamp for the old sliver for holding the old sliver S2 in cooperation with the old sliver upper clamp 41. The old sliver upper clamp 41 and the old sliver lower clamp 42 are also not shown, but the levers 27a, 27b ..., Rods 30a, 30b ..., and control cams 31a, 31b. Each of the driving means is configured to rotate in the vertical direction and can be opened / closed appropriately as needed.

In FIG. 9, reference numeral 61 denotes a gutter member rotatable between a standby position shown by a dotted line and an operating position shown by a solid line. One end of the gutter member 61 is a lower frame of the housing H. It is attached to a rotating shaft 62 which is supported by 63 via a suitable supporting member 64. The rotating shaft 62 is configured to have substantially the same length as the horizontal frame E along the horizontal frame E shown in FIG. 2, and the gutter member 61 is moved to the above-mentioned position by an appropriate driving means (not shown). It is rotationally driven so that it can be moved to either the standby position or the operating position.

Two gutter members 61 are installed on the rotary shaft 62 so as to be arranged between the sliver guide rollers G1 and G2 and G2 and G3 shown in FIG. The gutter member 61 stops the spinning unit that connects the sliver. For example, when the supply of the old sliver S2 is stopped, the sliver S2 hangs down by its own weight. In the lower part of the old sliver S2 stretched between the sliver guide rollers G1 and G2 and / or G2 and G3, the old sliver S2 is prevented from hanging down. In addition, it prevents the new sliver S1 drawn from the new can C1 shown in FIG. 2 for the sliver splicing from hanging down. Also, when the sliver on the empty can side after cutting the old sliver S 2 is returned to the empty can, it becomes a sliver guide.

Next, the positioning member N will be described with reference to FIGS. 8, 9, 12, and 13. In FIG. 9, reference numeral 65 denotes an index plate provided on a side wall of the support column D supporting the rail R, the side wall being arranged along the longitudinal direction of the spinning machine Sp, and at a position where the sliver splicing device P can precisely splice. It is installed corresponding to the spinning units S1 to S72 of the spinning machine Sp so as to be stopped. Further, 66 is provided for every one spinning unit in order to detect whether the spinning units S1 to S72 of the spinning machine Sp are odd spinning units S1, S3, S5 ... Or even spinning units S2, S4, S6. These are odd-numbered even-numbered spinning unit detection plates which are arranged above the index plate 65 and slightly displaced to the left as shown in FIG.

Reference numeral 67 is a fitting plate provided with a recess 67 a into which the index plate 65 can be fitted. As shown in FIG. 12, the fitting plate 67 is a shaft 69 mounted on the housing H. When the shaft 69 is rotated via the lever 68 by the operation of an appropriate actuator 70, the recess 67a of the fitting plate 67 engages with the index plate 65 as shown in FIG. However, the sliver splicing device P is stopped at a position where the sliver splicing can be accurately performed.

Reference numerals 72 and 73 denote sensors attached to the support frame 71 attached to the housing H. The sensor 72 is for detecting the position of the odd-numbered even-numbered spinning unit detection plate 66. The sensor 73 is for detecting the position of the index plate 65 arranged corresponding to each spinning unit. A limit switch 74 is operated by the fitting plate 67 when the recess 67a of the fitting plate 67 is engaged with the index plate 65, and serves to stop the driving of the spinning unit.

When the sensor 73 detects the predetermined position of the index plate 65, the actuator 70 is operated to rotate the fitting plate 67 to the right in FIG. 12, and as shown in FIG. By engaging the index plate 65 with the concave portion 67a of the fitting plate 67, the sliver splicing device P is stopped at an accurate position.

Further, as described above, the odd spinning units S1, S3, S5, ... And the even spinning units S2, S4, S6 ,. In the case where the sliver splicing is carried out all at once for each spinning unit S1, S3, S5 ... And for each even spinning unit S2, S4, S6 ..., as shown in FIG. For example, the odd and even spinning unit detection plate 66 is arranged corresponding to the odd spinning units S1, S3, S5 ..., The sensor 72 detects the odd and even spinning unit detection plate 66, and the sensor 73 is the index plate 65. When the position is detected, the actuator 70 is operated to rotate the fitting plate 67 to engage with the index plate 65. With this configuration, the sliver splicing device P can be stopped for the odd spinning units S1, S3, S5, ....

Further, when the sliver is spliced sequentially to the even spinning units S2, S4, S6, ..., The even spinning units S2, S4, S6 ,. Since 66 is not arranged, therefore, the sliver splicing device P is operated by operating the actuator 70 only when the sensor 72 is unresponsive and the sensor 73 detects the index plate 65. , S3, S5, ... Can be sequentially stopped only by the even spinning units S2, S4, S6.

In FIGS. 2 and 8, reference numeral 36 denotes a gutter that is arranged on the support column D along the longitudinal direction of the spinning machine Sp, and is an unnecessary gutter cut from the new sliver S1 gripped by the sliver gripping tool K. It is for accommodating and collecting the sliver. To connect to the end of the sliver S2 pulled out from the empty can B1, the remaining part of the new sliver S1 pulled out from the new can C1 and cut and held by the sliver holding device K is connected to the sliver holding device K. Is conveyed above the gutter 36, the sliver gripping tool K is opened on the upper part of the gutter 36, and the remaining part of the unnecessary new sliver S1 is accommodated on the gutter 36. After that, with the movement of the sliver splicing device P in the longitudinal direction of the spinning machine Sp after the sliver splicing work is completed, an appropriate position of the sliver splicing device P, for example, the lower end of the horizontal frame E as shown in FIG. A cleaning member, such as a comb-shaped member 75 attached to the section, which is slidable in the vertical direction scrapes up the remaining portion of the unnecessary new sliver S1 housed on the gutter 36, and is illustrated from the end of the gutter 36. Not stored in a suitable collection box. It is also possible to install a suction duct in the sliver splicing device P and to suction and remove the unnecessary remaining part of the new sliver S1 housed on the gutter 36 by the suction duct.

In the following, as an example, in FIG. 2, the old sliver S2 supplied from the can B1 to the spinning unit and the end Se of the new sliver S1 housed in the new can C1 are spliced together, as an example. The operation of P will be described with reference to FIGS. 14 to 20.

In response to a command from a predetermined control device, the wheels 2 are driven by a motor (not shown) and an appropriate transmission device so that the sliver joint device P travels along the rail R.

When the sensor 73 detects the designated position of the index plate 65, the actuator 70 is operated to rotate the fitting plate 67 to the right in FIG. The sliver splicing device P is stopped at an accurate position by engaging the index plate 65 with the concave portion 67a, and the limit switch 74 is actuated by the rotation of the fitting plate 67, and the sliver to the corresponding spinning unit is moved. Stop the supply.

Subsequently, the rotating shaft 62 shown in FIG. 9 is rotated to rotate the gutter member 61 from the standby position so as to receive the sliver droop between the sliver guide rollers G1 and G2 and G2 and G3. To move.

Next, the control cam 31 having a predetermined contour is rotated to move the operation casing M to the old sliver S2 stretched between the sliver guide rollers G3 and G4 in FIG. As shown in FIG. 14, the upper surface of the new lower sliver clamp 40, the upper surface of the old sliver lower clamp 42 and the upper surface of the lower piecing member 38 are lowered to a position where they can be scraped.

At the time of lowering the operation casing M described above, the upper clamp 39 for the new sliver and the lower clamp 40 for the new sliver are waiting in the upper and lower positions, respectively, while being opened, and the upper piecing member 37 is The upper piecing member 38 stands by downward, and the lower piecing member 38 stands by downward, the old sliver upper clamp 41 stands by upward, and the old sliver lower clamp 42 stands by by downward. Therefore, when the operation casing M descends, it is possible to prevent the old sliver S2 stretched between the sliver guide rollers G3 and G4 from coming into contact with the upper sliver upper clamp 39 and the like.

Next, the sliver guide roller is rotated by horizontally rotating the lower clamp 40 for the new sliver and similarly, horizontally rotating the lower piecing member 38 and the lower clamp 42 for the old sliver. The old driver S2, which is stretched between G3 and G4, is scooped and held horizontally.

Next, as shown in FIG. 14, the operating casing M is raised so that the upper surfaces of the lower piecing member 38 and the old sliver lower clamp 42 substantially coincide with the normal traveling position of the sliver.

Here, as shown in FIG. 14, the upper surface of the new lower sliver clamp 40 is located above the upper surfaces of the lower piecing member 38 and the old sliver lower clamp 42. Therefore, the old sliver S2 is bent between the upper surface of the new lower sliver clamp 40 and the upper surface of the lower piecing member 38.

Next, the old sliver upper clamp 41 is moved downward, and the old sliver upper clamp 41 and the old sliver lower clamp 42 grip the old sliver S2 as shown in FIG.

Next, in FIG. 2, the sliver gripping tool K is moved to the right and stopped at an appropriate position, for example, near the new sliver lower clamp 40, and the old sliver S2 is gripped by the sliver gripping tool K. To do. The gripping operation of the old sliver S2 by the sliver gripping tool K can also be performed while the operation casing M is being lowered and raised.

From this state, when the sliver gripping tool K is moved to the left in FIG. 2 and the old sliver S2 is pulled, the lower sliver lower clamp 40 in which the old sliver S2 is placed and bent is a kind. As shown in FIG. 16, the cutting end of the old sliver S2 is cut so as to form a tip shape as shown in FIG.

The sliver gripping tool K gripping the cut old waste sliver S2 is further moved leftward in FIG. 2 while dragging the old sliver S2 in the gutter member 61, and the empty can B1 The sliver gripping tool K is opened above, and the cut old sliver S2 is dropped into the empty can B1.

Next, the sliver gripping tool K further moves to the left in FIG. 2 and is attached to the tip of the vertical rod 11 of the vertical frame J which is connected by the elastic member 20 and is moving together. The moving sliver gripping tool L stops the movement of the sliver gripping tool K at a position substantially above the tip end Se of the new sliver S1 of the new can C1.

Next, the vertical rod 11 is lowered, the sliver gripping tool L is positioned to the side of the tip end Se of the new sliver S1 hanging from the mouth of the new can C1, and the vertical rod 16 is moved upward. Open the sliver clamps 12a and 12b, move the upper and lower rods 18 upward, and rotate the sliver clamps 12a and 12b from the vertical position toward the tip Se of the new sliver S1 to open the sliver clamps 12a and 12b. The tip Se of the new sliver S1 is inserted between them, and then the upper and lower rods 16 are moved downward to close the sliver clamps 12a and 12b and hold the tip Se of the new sliver S1.

In this state, the vertical rod 11 is raised, and the sliver gripping tool K simultaneously grips the lower part of the tip end Se of the new sliver S1 gripped by the sliver gripping tool L of the vertical rod 11 below the sliver gripping tool L. . The sliver clamps 12a and 12b of the sliver gripping tool L can be opened to transfer the tip end Se of the new sliver S1 from the sliver gripping tool L to the sliver gripping tool K.

Next, the sliver gripping tool K, which grips the tip end Se of the new sliver S1, is moved rightward over the operation casing M in FIG. Since the upper clamp 39 for the new sliver is kept open upward, the new sliver S1 which is gripped and moved by the sliver gripper K is for the new sliver that is open as shown in FIG. It passes between the upper clamp 39 and the lower clamp 40 for the new sliver and is placed on the upper clamp 41 for the old sliver. Here, the movement of the sliver gripping tool K is once stopped.

Here, since the upper surface of the old sliver upper clamp 41 is higher than the upper surface of the new sliver lower clamp 40, the new sliver S1 of FIG. It will bend on the left side.

Although the vertical frame J connected to the sliver gripping tool K by the elastic member 20 also moves to the right, the vertical frame J is provided with the stopper 21 provided on the horizontal frame E as described above. , And further rightward movement is blocked, and only the sliver gripping tool K continues to move rightward while extending the elastic member 20. Therefore, the new sliver S1 is cut between the sliver gripping tool L and the sliver gripping tool K, and the new sliver S1 is gripped only by the sliver gripping tool K.

As described above, until the vertical frame J contacts the stopper 21 provided on the horizontal frame E, the sliver gripping tool L and the sliver gripping tool K are closely connected by the elastic member 20. Therefore, the sliver existing between the gripping point of the sliver gripping tool L and the gripping point of the sliver gripping tool K is short, and therefore is cut between the sliver gripping tool L and the sliver gripping tool K. The cutting end of the new sliver S1 gripped by the tool K can be shortened so as not to hang down, and when the sliver gripping tool K moves to the right in the subsequent direction, the cutting end of the new sliver S1 may be changed to another sliver or It is possible to prevent contact with the base of the sliver splicing device.

Next, as shown in FIG. 18, the new sliver upper clamp 39 is lowered to grip the new sliver S1 between the new sliver upper clamp 39 and the new sliver lower clamp 40, and When the sliver gripping tool K, which has been temporarily stopped, is moved to the right again in FIG. 2, the old sliver S1 placed on the upper surface and bent is the same as the cutting of the old sliver S2 described above. The upper clamp 41 for use acts as a kind of obstacle, and as shown in FIG. 19, the cutting end of the new sliver S1 is cut at this portion so as to have a tip shape.

The remaining cutting ends gripped by the sliver gripping tool K move the sliver gripping tool K to the right in FIG. 2 up to the gutter 36 arranged along the longitudinal direction of the spinning machine Sp, The unnecessary new sliver S1 is accommodated in the gutter 36 by opening the sliver gripping tool K.

Next, as shown in FIG. 10, by pivoting the lever 27c downward, the upper pressing member 45 abuts behind the upper piecing member 37 at the upper standby position, The piecing member 37 is placed on the overlapping portion of the new sliver S1 and the old sliver S2 as shown in FIG.

Next, as shown in FIG. 9, the rotating plate 47 is rotated in the normal and reverse directions so that the upper piecing member 37 and the lower piecing member 38 reciprocate left and right with a predetermined width. By the left and right reciprocating motions of the upper piecing member 37 and the lower piecing member 38, the overlapping portion of the new sliver S1 and the old sliver S2 is rubbed and the new sliver S1 and the old sliver S2 are joined. Become.

As described above, since the shaft 50 of the upper piecing member 37 and the shaft 53 of the lower piecing member 38 are attached to the peripheral portion of the rotary plate 47 with a phase difference of 180 degrees, the rotary plate 47 is left and right. When reciprocating in the direction, the upper piecing member 37 and the lower piercing member 38 move in opposite directions, so that the overlapping portions of the new sliver S1 and the old sliver S2 that are always rubbed are at the same position. Since the position of the overlapped portion of the new sliver S1 and the old sliver S2 that are held and massaged does not shift to the left and right in FIG. 9, unnecessary tension is not applied to the new sliver S1 and the old sliver S2. Therefore, the new sliver S1 or the old sliver S2 may be cut, or the new sliver S1 and the old sliver S2 may be pulled to shorten the overlapping portion of the new sliver S1 and the old sliver S2, and the sliver may be cut at this part. Nothing.

When the new sliver S1 and the old sliver S2 are spliced together, the new sliver upper clamp 39, the new sliver lower clamp 40, the old sliver upper clamp 41 and the old sliver are operated by the operation opposite to the above-mentioned operation. The lower clamp 42 for use and the upper piecing member 37 and the lower piecing member 38 are respectively rotated in the vertical direction, and the fitting plate 67 is shown in FIG. 12 from the positioning position shown in FIG. Thus, the concave portion 67a of the fitting plate 67 is returned to the position released from the index plate 65, the operation of the limit switch 74 is released, the drive to the spinning unit is restarted, and the new sliver S1 is supplied to the spinning unit.

At the same time, the gutter member 61 is returned to the standby position shown by the dotted line in FIG. 9, and the operating casing M of the sliver splicing device P is further raised so as to be located in the housing H, so that the splicer joint 1 is moved to the first position. The cycle is complete.

The operational effects of the above-described embodiments of the present invention will be listed below.

Since the cutting end of the new sliver which is cut between the vertically moving sliver gripping tool and the horizontally moving sliver gripping tool is cut short so as not to sag, Then, when the horizontally moving sliver gripping tool is moved to the right, troubles such as the cutting end of the new sliver contacting another sliver and cutting the other sliver can be prevented.

Since the sliver splicing device is appropriately moved above the spinning unit that requires the sliver splicing to automatically perform the sliver splicing, labor and space can be saved.

Since the sliver splicing is automatically performed, it is possible to always obtain a constant sliver splicing portion, and it is possible to appropriately adjust the state of the sliver splicing portion such as the entanglement state of the sliver comrades as necessary. it can.

When cutting the old and new sliver, a clamp for placing a part of the old and new sliver and lifting it up is arranged, and then the old and new sliver is pulled by the lateral direction to cut the old and new sliver. The cut end of the sliver becomes a tip, and when the cut ends of the old and new sliver are polymerized, the overlapped part does not become thick.

Since the old sliver extending from the empty can that has been cut for sliver splicing is automatically returned to the empty can and accommodated therein, the sliver hanging from the empty can to the spinning machine or the like can be stored. Trouble due to entanglement can be prevented, and a space for such manual work is unnecessary.

Since the gutter member for preventing the sliver of the old sliver and the new sliver from dripping is arranged, troubles such as cutting of the sliver and entanglement of the sliver due to the dripping can be prevented.

Since the unnecessary cutting end of the new sliver is automatically recovered, it is possible to prevent such troubles that the unnecessary cutting end adheres to the spinning machine and save labor. Can be realized.

Since the sliver end is automatically gripped and taken out from the new can placed behind the spinning machine, the space behind the spinning machine can be greatly reduced and labor can be saved. .

Since the overlapping part at the end of the new sliver and the overlapping part of the end of the old sliver are joined by rubbing between a pair of piecing members that reciprocate in opposite directions, the overlapping part is also formed during the rubbing operation. The position of the sliver does not shift, so that unnecessary tension is not applied to the new sliver and the old sliver, and the new sliver or the old sliver is not cut.

Further, the stroke of the piecing member is half as compared with the case where only one side is moved, which enables speeding up and space saving.
