PURPOSE:To equalize the number of bobbin hangers on a bobbin carriage on a spare rail to that of small package bobbins, by temporarily depositing a pair of small package or full bobbins in a sliver exchanging machine prior to sliver exchanging operation. CONSTITUTION:A pair of small package or full bobbins to be initially exchanged are temporarily deposited in a sliver exchanging machine 30 through two bobbin holding tools 150 and sliver exchange is carried out by exchanging bobbins hung from bobbin hangers 12 on a creel of a spinning machine with full bobbins hung from bobbin hangers 15 of each spare rail 13 with the sliver exchanging machine 30 for each pair of the front and back full bobbins. In carrying out the final sliver exchanging operation, the pair of the small package or full bobbins on the bobbin holding tools are transferred to the bobbin hanger on the spare rail. Thereby a U-turn is not required for a bobbin carriage 14.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for replacing a wire in a spinning machine and a wire exchanger more preferable for carrying out the method.

More specifically, when the M-volume bobbins suspended from the front and rear two rows of bobbin hangers on the creel of a spinning machine become empty or become small bobbins, these bobbins are replaced with the bobbins to be replaced on the creel of the spinning machine. The present invention relates to a method for exchanging a full bobbin suspended from a bobbin hanger on a spare rail having the same number of bobbin hangers as the number of bobbin hangers, and a more preferable exchanger for carrying out the method.

[Problems to be solved by the conventional technology and invention] When the Shinomaki bobbin hanging on the bobbin hanger of the spinning machine becomes empty or becomes a small bobbin, it is difficult to replace the Shinomaki bobbin with a full bobbin. It is necessary to replace it.

In order to save labor in the spinning process, automation of the spinning machine replacement process is also required, and various proposals have been made. For example, in the Shino exchange method disclosed in Japanese Patent Publication No. 61-1533, Shino windings of the same size are installed in each of the front and rear rows of the creel of a spinning machine, and when the bobbin in the front row becomes a small bobbin, The small bobbin is being replaced with a full bobbin on the spare rail. On the other hand, JP-A-61-1
No. 02428 and Japanese Patent Application Laid-Open No. 61-119728 disclose that one or two spare rails are arranged above the creel of the spinning machine, and a full bobbin and the spinning machine are suspended from a bobbin hanger on the spare rail. A method has been proposed in which small bobbins suspended from two rows of bobbin hangers, front and rear, of a creel are replaced in pairs.

In these conventional Shino replacement methods, a spare bobbin hanger is first installed on the bobbin carriage running on a spare rail to hang the empty or small bobbin (hereinafter collectively referred to as small bobbin) that has been removed from the spinning machine. There must be. In other words, if the number of small bobbins to be replaced on one side of a spinning frame is N, at least one spare bobbin hanger must be provided on the bobbin carriage, so a total of N+1 bobbin hangers must be provided on the bobbin carriage. In addition, when replacing the threads in two pairs of front and rear bobbins, two spare bobbin hangers, therefore a total of N+2 bobbin hangers, must be provided on the bobbin carriage. 1st
FIG. 8(A) shows the arrangement of the bobbin hanger 15 on the bobbin carriage 14 before the wire is replaced in the latter case of JP-A-61-119728. Arrow X in the figure
indicates the direction of Shino exchange progress of the Shino exchange machine. Therefore, when you hang a full bobbin on the bobbin carriage and start replacing the bobbin, prepare a spare bobbin hanger (1 in Figure 18 (A)).
5. , 15□) must be on the tip side of the bobbin carriage, that is, on the side where the first one or two bobbins are replaced in the Shino exchange machine, but when the Shino exchange is finished, that is, when the empty bobbin is suspended, the bobbin carriage There is a spare bobbin hanger on the rear end side (15. in Fig. 18(B)).
．． 157.2). For this reason, the spare bobbin hanger is located on the opposite side facing the spinning machine before and after the Shino replacement. For this purpose, the carriage with the empty bobbin suspended after Shino replacement is transported to the upper part of the spinning machine.
-The automatic tube changing device of the roving frame disclosed in No. 119730 etc. is used to replace the full bobbin wound up by the roving frame, and the bobbin carriage is reversed when the bobbin carriage with the full bobbin suspended is conveyed to the spinning frame again. I have to let it happen. In other words, the long bobbin carriage, which is approximately equivalent to the entire length of the spinning frame, must be made a U-turn while being transported between the spinning frame and the roving frame using the bobbin carriage. It was difficult to automatically transport and control the materials. Furthermore, in recent years, long spinning frames have been put into practical use, and when bobbin carriages full of bobbins doffed by two (or twice) roving frames are connected and fed to the spinning frame, one or two bobbin carriages are connected to the spinning frame. Since there is a spare bobbin hanger, it is impossible to supply a full bobbin corresponding to the connecting part, and automatic replacement is impossible.

The present invention solves such problems and provides a method for replacing the bobbins by providing the same number of bobbin hangers on the bobbin carriage of the spare rail as the number N of empty bobbins of the spinning machine to be replaced;
The purpose of the present invention is to provide a Shino switching device for carrying out the method.

[Means for Solving the Problems] The object of the present invention is to improve the bobbin hangers of the bobbin carriages of the bobbin carriages of the spare rail provided above the creel of the spinning machine. A bobbin exchange method in which full bobbins suspended from a spinning machine are exchanged in pairs, front and rear, by a bobbin exchanger running along a spinning machine stand, the bobbin exchanger being provided with a pair of bobbin holders, The first pair of small bobbins or full bobbins to be replaced are temporarily deposited in the bobbin holder, and while they are being deposited, a series of thread changes are carried out sequentially along the spinning machine. This is accomplished by a thread change method that completes the thread change from one end of the spinning machine to the other end by transferring a small bobbin or a full bobbin to a bobbin hanger on a predetermined spare rail or a pair of front and rear bobbin hangers.

A second Shino exchanger for carrying out the above Shino exchange method is characterized in that the main body of the Shino exchanger is provided with two bobbin holders for temporarily holding a pair of small bobbins or full bobbins to be exchanged first.

The bobbin holder 150 is fixedly installed on the Shino exchanger 30 and supported by a pillar 151 extending upward. This bobbin holder 150 is installed within the movable range of the peg unit 40 in a position where it does not interfere when the peg unit 40 places a full bobbin or a small bobbin on the bed for replacement. As shown in FIG. 3, the bobbin holder 150 of the embodiment has U-shaped holding parts 150a that are open on both sides of an arc-shaped connecting part 161 toward the center of rotation of the begging unit.
The flange of a full bobbin or a small bobbin is suspended and held from the U-shaped holding part 150a by a flat holding member having a shape. The interval C between the two holding parts 150a, 150a is the same as the interval a between the bobbin hangers of the spare rail.

The bobbin holder 150 may have any shape or mechanism as long as it can temporarily hold the small bobbin 2 or the full bobbin 1. Figure 4 shows bobbin holder 1.
Examples of 50 different types are shown. The bobbin holder 152 shown in plan view in FIG. 4 is a gripper type bobbin holder, and has gripping surfaces 154a and 154b inside thereof for gripping the intermediate portion of the roving bobbin of the small bobbin 2, respectively. shaped gripping members 153a, 153b

The cheno wheel 74b is rotatably fitted loosely to a pin installed in the upper pillar bracket 73b and the cheno wheel 74b.
6 is suspended, and its chain 76 is fixed to a slider 77 by chain holders 78a and 78b. The slider 77 has two support doors 9a and 79b.
is fixed vertically, and its support Ron door 9a, 79b
A support 96 that supports the peg unit 40 is fixed to the upper end of the peg unit 40 . Therefore, when the first motor 71 is energized, the elevating device 70 moves the slider 77 up and down via the chain 76, and the peg unit support 96 supporting the peg unit 40 moves up and down accordingly.

As shown in FIGS. 6 and 7, a hollow shaft 94 is rotatably supported on the support 96 via bearings 97a and 97b, and a motor 91 of the displacement device 90 is further fixed thereto. The upper part of the hollow shaft 94 rotatably supports the drive shaft 64 via a bearing 66a, and a lower drive shaft support bracket 93 is fixed to the lower part of the hollow shaft 94. It is rotatably supported by a support bracket 93. A motor (hereinafter referred to as a second motor) 81 for the longitudinal movement device 60 is fixed below the support bracket 93 using bolts. A drive gear 68 attached to the motor shaft 67 of the second motor 81 and a gear fixed to the lower end of the drive shaft 64 mesh with each other, and the peg unit drive gear 65 is fixed to the upper part of the drive shaft 64.

The upper part of the hollow shaft 94 is formed into a large diameter gear 98, and the slide base 41 is bolted to the gear 98.

As shown in FIGS. 7 and 8, the peg unit 40 includes a slide base 41 fixed to a hollow shaft 94, a first slider 42 sliding on the slide base 41, and a first slider 42 sliding on the first slider. It consists of 2 sliders. That is, the slide base 41 has a cross-sectional shape, and a tenth bolt 44 is bolted to the upper surface of an ear portion 41a with both ends in the front and back direction (left and right ends in FIG. 7) bent outward. . Only one bolt on the front side protrudes upward and also serves as a stopper pin 57.

Colors 52a and 52b are provided on the top surface of the slide base 4I.
A second rack 52 is secured via the (FIG. 8). Like the slide base, the first slider 42 is also formed in a cross-sectional shape, and a 20th rod 45 is bolted to the ears at both ends in the front and back direction. Bearing portions 47 protruding from both sides of the first slider 41 are slidably fitted into the tenth prong 44 of the slide base 41. 1st slider 4
A first rack 51 meshing with the gear 65 of the drive shaft is fixed to the lower surface of the drive shaft 2, and a pinion 54 is rotatably supported on the upper surface of the drive shaft. 2
The third slider fixed to the lower surface of the rack 52 and the second slider 43
It is engaged with the rack 53. And the first slider 4
A long slot 42a is formed in the lower surface of the rack 2 so as not to interfere with the movement of the second rack 52. Second
The slider 43 is also formed in a cross-sectional shape, and the bearing portions 48 protruding from both sides of the slider 43 are connected to the 20th protrusion 4 of the first slider.
5 so that it can slide freely. A peg 35 is fixed to the front end of the second slider 43, and the peg 36 is slidably fitted into a 30th node 46 attached to the upper surface of the bottom plate of the second slider 43. Then, as shown in FIGS. 9 and 10, the wire 6 is inserted into the second slider 43 by a coiled spring 59.
A wire drum 58 is provided which is biased in the direction of winding up the wire 61, and the wire 61 passes through a guide roller 62, and the wire hook 6 whose tip is attached to the front side of the peg 36 is provided.
It is bound to 1a. Therefore, the peg 36 which is slidable on the 30th sleeve 36 is pulled forward and positioned against the stopper 63 for the mounting base of the 30th sleeve 43, which is fixed to the second slider 43.

At this time, the distance a between the legs 35 and 36 matches the distance a between the bobbin hangers of the spare rail. A locking piece 56 is attached to the side surface of the peg 36 so as to protrude from between the bearing part 47 of the first slider and the bearing part 48 of the second slider.

In this way, the peg unit 40 is configured such that the first slider 42 and the second slider 43 move back and forth using the telescopic mechanism. That is, when the second motor 81 is operated, its rotation is transmitted to the drive shaft 64 through the gears 68 and 69, which rotates the drive gear 65 and moves the first rack 51, so that the first slider 42 moves toward the slide base 41.
Slide on top to move forward. At this time, the pinion 54 on the first slider 42 also moves together with the first slider 42 and rotates while meshing with the second rack 52 fixed to the slide base 41. Therefore, the circumferential speed of the pinion 54 is twice the linear speed of the first slider 42 because the center of the pinion 54 rotates around the center itself while moving. Since this pinion 54 is meshed with the third rack 53 fixed to the second slider 43, the second slider 43
slides on the first slider 42 at twice the speed and moves forward.

During this forward movement, the locking piece of the peg 36 comes into contact with the stopper pin 57 of the slide base to prevent the peg 36 from moving forward. Further, the first slider 42 and the second slider 43 continue to move forward, and at this time, the peg 36 moves relatively backward into the second slider 43 against the biasing force of the coil spring 58, and thus reaches the forward end. As a result, the first and second sliders 42 and 43 are in the state shown by the imaginary lines in FIGS. 7 and 9, and the distance between the pegs 35 and 36 is equal to the creel distance of the spinning machine. When retreating, a second
The stopper 63 of the slider 43 comes into contact with the peg 36, and then moves back while maintaining the distance a between the begs 35 and the pegs 36, returning to the standby position shown by the solid line in FIG.

Next, the Shino exchange method performed by the aforementioned Shino exchange machine 30 will be explained based on the schematic plan views of FIGS. 12 and 13.

As mentioned above, when replacing the thread, the medium elongated bobbin 120F is attached to the bobbin hanger 12 of the creel of the spinning machine.

120B and small bobbin 2F, 2B are suspended alternately, 1
A number of full bobbins 1 corresponding to the number of small bobbins on the creel of the spinning machine to be replaced are suspended on the spare rail, as shown in FIG. 11. The Shino exchanger, which was traveling along the machine base in the direction shown by arrow X in Figure 11, was the first empty bobbin 2F.

It stops at the position where the peg unit 40 faces 2B (
Figures 11 and 12 (1)).

First, when the forward and backward movement position is activated, the telescopic pink mechanism moves the pegs 35 and 36 on the peg unit 40 forward and widens the distance between them, so that the peg 35 is placed directly below the small bobbin 2B, and the peg 36 is placed directly below the small bobbin 2F. (Fig. 12 (2)). Next, the lifting device 70 is operated to raise the peg unit 40, remove the small bobbins 2B and 2F from the bobbin hanger 12 of the creel of the spinning machine, and lower the peg unit 40. Next, the pegs 35 and 36 move back, reduce the distance between them, and return to their original positions (FIG. 12(3)). After that, the peg unit 40 is a displacement device 9
0, the small bobbin 2B on the peg 35 is moved forward slightly so as not to interfere with the bobbin holder 150 (FIG. 13 (4)), and then reaches a position facing the bobbin holder 150. Figure 12 (
5)) Then, the pesog unit) 40 is slightly raised and moved forward to attach the small bobbin 2B to the small bobbin holder 150.
After loading 2F, by lowering the peg unit 40, the small bobbin 2 placed on the pegs 35 and 36 is removed.
B.

2F is suspended from the bobbin holder 150. (Figure 12 (
6)). After the peg unit 40 containing the pegs 35 and 36, now free, is moved back, it is rotated counterclockwise as shown by the arrow by the operation of the displacement device, and the two full bobbins IB and IF are moved directly under the two full bobbins IB and IF. advance. At that position, the lifting device 70 operates and the peg unit 4
0 rises, full bobbin IB, remove 1F and peg 35
, 36 full bobbin IB.

It is lowered with the IF placed thereon (FIG. 12 (7)).

Next, the pegs 35 and 36 are slightly retracted and then rotated 90'' clockwise as shown by the arrows (Fig. 12 (8)).
). Then, the pegs 35 and 36 move forward and widen the distance between the bobbins to fill each full bobbin IB.

1F first reaches directly below the bobbin hanger 12 on the creel of the spinning machine, which is empty after the small bobbins 2F and 2B have been removed. Next, the lifting device 70 is operated to raise the peg unit, and the full bobbin IB on the pegs 35 and 36 is lifted.
Attach the IF to the bobbin hanger 12 (12th (9)
). Next, the peg unit 40 is lowered and retracted to return to its original position (FIG. 12 (10)), thus completing the first cycle of replacement, and at this time the bobbin carriage 14 of the spare rail 13 is fully loaded. Removed and empty bobbin hanger 15. ．． 15□, and the next cycle's Shino exchange machine will use this empty bobbin hanger 15. ．． This is done by transferring the small bobbin on the creel of the spinning machine to 15□. The work procedure is the same as the first cycle of wire replacement shown in FIG. 12(1) to FIG. 12(4), and the peg unit 40 shown in FIG. 12(4) rotates 90" to replace the spare rail. in the longitudinally oriented position corresponds directly below the empty bobbin hangers 15+, 15□ on the spare rail.

Therefore, in the position shown in FIG. 12 (4), the bed unit 4
By activating the lifting device 7o of peg 3
The small bobbins 2B and 2F on 5 and 36 are suspended by the bobbin hanger 15□15□. Next, after lowering the peg unit 40, FIGS. 12(7) to 12(10)
), and the next cycle of replacement work is completed. Thereafter, this operation is repeated until the other end of the spinning machine is reached, and at the final stage, as shown in FIG. 13(1), the bobbin hangers 15N-+, 15. becomes empty.

Therefore, finally, by transferring the small bobbins temporarily stored in the bobbin holder 150 to the bobbin hangers 15N-, , 15, the replacement for one machine is completed. The work procedure will be explained based on FIGS. 1:3 (1) to (5). First, the peg unit 40 rotates clockwise by the operation of the displacement device 90, and then moves forward slightly and then rises to temporarily hold the pegs 35 and 36 in the bobbin holder 150 to hold the small bobbin 2B.

2F (Fig. 13 (2)). Next, the peg unit 40 moves back slightly, and the small bobbins 2B and 2F on the pegs 35 and 36 are removed from the bobbin holder 150, and then lowers (FIG. 13(3)). Next, Betsu unit 4
0 is rotated counterclockwise by the operation of the displacement device 90, and the small bobbins 2B and 2F are positioned directly below the small bobbins suspended from the spare rail.

(Figure 13 (4)). In this state, the Shino exchange machine 30 is
) The small bobbins 2B and 2F placed on the begs 35 and 36 of the peg unit 40 move forward by two bobbin hangers of the bobbin carriage 4 of the i-rail 13 (one movement of the Shino exchanger 30). Bobbin hanger 15. ,1
5□1, and then the small bobbin 22 is moved to the bobbin hanger 15 by the vertical movement of the penog unit 40.
N, 15. , (Fig. 14 (5)). In this way, the wire replacement work on one side of one spinning machine is completed.

In the improved embodiment, in order to make the Shino exchanger 30 smaller, when the full bobbin placed on the begging unit 40 is rotated 90 degrees in the step (8) in FIG. 12, the small bobbin suspended from the bobbin holder 150 The bobbin holder 150 is installed close to the center of rotation of the peg unit 40 within a range where it does not interfere. For that purpose, hold the small bobbin with the bobbin holder 15.
0, the peg unit 40 is rotated and moved forward as shown in steps (5) and (6) in FIG. The small bobbin can be held by the bobbin holder 150. In the above embodiment, the distance a between the pegs 35 and 36 does not change since the amount of forward and backward movement of the bed unit 40 in FIGS. 12(4) to 12(8) is small. Also, if the Shino exchanger 30 is moved away from the machine base, the Betsu unit 40 can be reversed by 180 degrees instead of moving the Shino exchanger in the step (5) in FIG. ) or Shino exchange [movement of 30 and Figure 13 (1) to (
The work 4) may be performed in parallel.

Next, a second example of a spinning machine changing method according to the present invention in a case where two spare rails are arranged in front of the bobbin row in the front row of the creel of a spinning machine and an example of a spinning machine for carrying out the method will be explained. This will be explained as an example.

In the case of this embodiment, as shown in Fig. 16, the same number of full bobbins as the small bobbins suspended on the creel of the spinning machine are placed on two spare rails provided in front of the creel of the spinning machine. A pair of full bobbins are suspended at a position facing the small bobbin with a distance a from front to back. A full bobbin is not placed in the position opposite to the first pair of small bobbins 2B and 2F, and the Shino exchange 4a30 that has traveled along the machine base has pegs 35 and 36 of the bed unit 40 in a position where a full bobbin is not placed. The train will stop at that point, and the Shino exchange will take place at that location.

This Shino exchanger 30 has two bobbin holders 15 for temporarily storing a pair of small bobbins or full bobbins to be exchanged first.
0, and when the distance between the pair of begs 35 and 36 is changed between the bobbin hangers before and after the creel using a telescopic pink mechanism, the spacing between the spare rail and the bobbin hanger is changed to a. The device 60 and the lifting device 70 for lifting and lowering the peg unit 40 are substantially the same as those in the first embodiment. Since the displacement device 100 that moves the peg unit 40 to correspond to the position directly below the empty bobbin hanger on the spare rail and the position directly below the full bobbin on the spare rail is different, only the different parts will be explained below.

As shown in FIGS. 14 and 15, four pin connecting members 113 are attached to the lower surface of the bottom plate of the slide base 41 on the front, back, left and right, and support shafts 167 are implanted on the left and right sides of the front and rear surfaces of the slider 77, respectively. Four equal length support rods 105
a, 105b, 106a, and 106b are rotatably connected to the support shaft 107 and the pin 108 of the pin connection member 113. That is, four support rods 105a.

The IC) 5b, 106a, 106b, the slide base 41, and the slider 77 constitute a parallel link mechanism, and the Pesog unit) 40 is horizontally supported and rotates in the left-right direction (toward the machine frame of the spinning machine) around the spindle 107. Supported so that it can swing freely. A motor mounting bracket lO9 is fixed to the rear surface of the slider 77 (left side surface in FIG. 14), and a displacement device motor (hereinafter referred to as the fourth motor) is mounted on the motor mounting bracket lO9.

Next, the peg unit is moved forward, the full bobbin is removed, the full bobbin is attached to the bobbin hanger 12 of the creel of the spinning machine (Fig. 17 (7)), and the peg unit 40 is returned to its original position (Fig. 17 (7)). 8)) At this time, there are a pair of empty bobbin hangers on the bobbin carriage 14 of the spare rail 13, and after that, the bobbin hangers on the bobbin carriage 14 of the empty spare rail 13 will be replaced. This is done repeatedly by transferring a pair of small bobbins on the creel of the spinning machine to the hanger. As a result, a pair of empty bobbin hangers remain at the final end of the bobbin carriage 14 of the spare rail 13 when the final cycle of the thread exchange is completed, and therefore, a pair of empty bobbin hangers is attached to the bobbin holder 150 on the thread exchanger 30. By transferring the deposited small bobbin using the peg unit 40, spinning J! Completed replacement of one side of one car.

In the description of the working procedure of the Shino exchange method of the first and second embodiments, the procedure was described as a procedure for depositing a small bobbin into the bobbin holder of the Shino exchange machine.

However, before starting the bobbin exchange, the pair of full bobbins is placed in the bobbin holder to empty the pair of bobbin hangers at the most extreme end of the bobbin carriage on the spare rail, and the bobbin exchange continues with these empty bobbin hangers. In the final thread exchange cycle, the full bobbin deposited in the bobbin holder may be suspended from a bobbin hanger on a creel at the final end of the spinning machine, thereby completing the thread exchange on one side of the spinning machine.

Incidentally, in the above embodiment, a Shino exchanger 30 that performs Shino exchange using a pair of bets 35 and 36 has been described, but as in the known Shino exchanger, a pair of Begs for a full bobbin [f] are used as a pair of Begs for placing an empty bobbin. It goes without saying that the installation of two bobbin holders in a Shino exchange machine that performs a Shino exchange can be carried out in the same manner.

[Effects of the Invention] The Shino exchange method according to the present invention is configured such that a pair of small bobbins or full bobbins is temporarily deposited in the Shino exchange machine prior to starting the Shino exchange work, so it is easy to carry out the Shino exchange prior to the Shino exchange work. The number of bobbin hangers on the bobbin carriage of the spare rail can be made equal to the number of small bobbins to be replaced. As a result, when performing thread replacement work in conjunction with the automatic pipe changing device of the spinning machine, the bobbin carriage
There is no need to turn the bobbin, and therefore automatic conveyance between a plurality of roving frames and fine spinning machines using a bobbin carriage can be easily and conveniently carried out using convenient equipment. Further, it becomes possible to automatically convey full bobbins by the bobbin carriage even to a long spinning machine in which full bobbins doffed by two (or two) roving frames are connected in a row.
