Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tube supply device for an automatic winder.

Generally, the pipe yarns from the spinning machine are removed all at once from the spindle of the spinning machine and once accumulated, and then supplied to a winder in the required number. As a device for reliably supplying the pipe and yarn by simple means without damaging the surface of the yarn layer of the pipe in this feeding process, the present applicant has previously proposed, for example, Japanese Patent Application Laid-Open No. 57-141362.
We proposed something like the one shown in the publication. In this method, the pipe yarn is inserted into a peg set on a disc-shaped carrier and made to stand upright, and after the carrier is transported by a conveyor, it is transferred onto a rotating disc and transported to a winding position.

Although this method effectively achieved the intended purpose,
The following requirements have been added to this method. The aim is to more quickly and smoothly exchange the tube yarn at the winding position, thereby making the timing of the tube yarn exchange operation and the yarn tying operation by the winding unit more reliable.

In other words, the yarn end of the newly supplied yarn to the winding position is blown upward by air or the like at the same time as the feeding operation is completed, and this blown yarn end is sent to the waiting suction pipe. The thread is suction-grasped, tied to the thread end on the winding package side, and wound up. However, if there is a delay in the supply of the yarn, the air blows up the thread end, and the suction pipe is unable to grasp the thread end. Mistakes may occur. That is, in the device disclosed in the above-mentioned publication, the carriers at the winding position are located in continuous contact with each other from the entrance of the carrier inlet passage of the unit, and therefore, a plurality of carriers are continuously transferred on the conveyor. When the carrier is in the winding position, the carrier on the conveyor is connected to the carrier in the winding position, and the pressing force due to the running force of the conveyor is propagated to the carrier in the winding position. A large load may be applied, making it impossible to discharge or causing the timing of discharge to be delayed.

In view of the above points, the present invention maintains a non-contact state between the carrier into which the empty tube yarn is inserted after winding is completed and the carrier to be supplied to the next winding position, thereby supplying the tube yarn. Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of the device according to the present invention, in which U indicates a large number of winding units arranged at regular intervals in the front and back direction of the paper, and 1 and 2 refer to the winding units 1 and 2 extending along and below the units U in the front and rear directions of the paper. a running belt conveyor,
Reference numeral 3 denotes a pipe supply and discharge device disposed between both conveyors 1 and 2.

The yarn supply conveyor 1 transports the yarn 4 in the state shown in FIG. The hollow, disk-shaped carrier 5 has a peg 7 planted in the center via a step 6, and the tube thread 4
Insert the lower end of the woodwind 8 into the peg 7 and
A through hole 10 is provided at the tip of the peg 7 to communicate the hollow part in the carrier 5 with the center hole 9 of the woodwind 8, and the end Y of the pipe thread 4 is exposed. and is suspended within the center hole 9.

The tube yarn supply conveyor 1 and the tube yarn discharge conveyor 2 are arranged with a difference in level between the upper and lower sides, and the tube yarn supply and discharge device 3 is provided in a form that diagonally communicates between them. The yarn is carried from the yarn supply conveyor 1 to the winding position 11 in the yarn supply and discharge device 3, wound up into a package (not shown) by a winder U, discharged as an empty wood tube 8, and conveyed by the yarn discharge conveyor 2. .

Details of the tube supply and discharge device 3 are shown in FIGS. 3 and 4.
As shown in the figure. First and second guide plates 13 and 14 forming a curved passage 12 for the carrier 5 are fixed to the unit machine between both conveyors 1 and 2, and the lower surface of the carry-in passage 12a is a freely rotating disc. 15, and a bottom plate 16 formed by bending the first guide plate 13 is provided on the lower surface of the discharge side passage 12b. Tube yarn supply conveyor 1, disk 15, bottom plate 16
The pipe discharge conveyor 2 and the pipe discharge conveyor 2 form substantially the same continuous plane, and a part of the disc 15 is in contact with the pipe supply conveyor 1 and is applied with a rotational force in the direction of the arrow a about the shaft 17. There is. The pipe supply conveyor 1 is further provided with a third guide plate 18, which guides some of the carriers 5 transferred in the direction of arrow b by the supply conveyor 1 into the carry-in passage 1.
2a and allows the excess carrier 5 to pass through.

The first guide plate 13 has a free roller 1 at its tip.
A first stopper 20 having a diameter of 9 is supported by a shaft 21, is urged to rotate in the direction of arrow c by a spring 22, and is stopped from rotating by contacting a pin 23. When in contact with the pin 23, the first stopper 20 has a convex portion 25 that makes the first bending portion of the passage 12, that is, the exit of the yarn waiting position 24, narrower than the outer diameter of the stepped portion 6 of the carrier 5. The carriers 5 guided into the carry-in passage 12a from the pipe supply conveyor 1 are stopped at the standby position 24, and two carriers 5 are always kept in the carry-in passage 12a.
We are trying to ensure that.

A second stopper 26 and a balloon guide 27 are supported by shafts 28 and 29, respectively, on the second guide plate 14, and a shaft 3 provided on the second stopper 26 is supported by shafts 28 and 29, respectively.
0 is always in contact with the inner surface of the balloon guide 27.

The second stopper 26 is connected to the carrier 5 at the second bending part of the passage 12, that is, at the above-mentioned yarn winding position 11.
It has a recess 31 that can hold and hold the stepped portion 6, and the other side is an arcuate roller support edge 32 centered on the shaft 28. The balloon guide 27, which has a flat curved plate 33 at its tip, is urged to rotate in the direction of arrow d by a spring (not shown), and is prevented from rotating by the shaft 30 that abuts its inner edge.

The yarn winding position 11 is located on a disc 15, and when the carrier 5 is located in the winding position 11, there is an arc shaped part centered on the shaft 17 on the part of the disc 15 that corresponds to the center of the peg 7. A plurality of through holes 34 are provided, and a nozzle 3 that spouts compressed air toward the through holes 34 is located at the center of the peg 7 below the through holes 34.
5 is provided. A valve 38 is provided between the nozzle 35 and an air hose 36 that sends out air, and the opening and closing of the valve 38 is controlled by a lever 37. Therefore, it passes through the valve 38, enters the hollow part in the carrier 5 from the nozzle 35 through the through hole 34 of the disc 15, and further flows into the central hole 9 of the wood pipe 8 through the through hole 10 of the peg 7. The yarn end Y hanging down inside the center hole 9 is blown upward.

The blown-up yarn end Y passes through the yarn guide 40 fixed to the winding unit U, is suction-grasped by a suction pipe 41 waiting above, is tied to the yarn end on the side of the package cage (not shown), and is wound up. It will be done.

The operation of the yarn supplying and discharging device 3 will be explained with reference to FIGS. 3 and 4. First, in FIG. 3 showing a normal winding state, the carrier 5 is at the winding position
Two pieces are respectively located in the carry-in passage 12a.

At this time, the first carrier 5 in the winding position 11
The carrier 5a is stopped with its stepped portion 6 supported within the recessed portion 31 of the second stopper 26, and the second carrier 5b in the standby position 24 has its stepped portion 6 held in the convex portion 25 of the first stopper 20. They are brought into contact with each other and are prevented from being fed by the disk 15.

Further, the curved plate 33 of the balloon guide 27 is interposed between the first carrier 5a and the second carrier 5b, and the pipe thread 4 in the first carrier 5a is
The thread balloon accompanying the thread unwinding is the second carrier 5.
This is done so as not to affect the pipe thread 4 in b.

When winding of the tube yarn 4 in the first carrier 5a is completed in this state, this is sensed by the winding unit U and a solenoid (not shown) is actuated to rotate the shaft 28 by a certain angle.

As a result, the second stopper 26 rotates to the left as shown in FIG. 4 while holding the first carrier 5a in its recess 31, and moves the first carrier 5a from the discharge side passage 12b onto the pipe discharge conveyor 2. discharge to.

As the second stopper 26 rotates, its shaft 3
0 moves while pressing the inner surface of the balloon guide 27 to turn it to the right, and furthermore, the roller bearing edge 32 of the second stopper 26 comes into contact with the free roller 19 of the first stopper 20 and the stopper 20 is rotated. The convex portion 25 is retracted to the left.

Therefore, the second carrier 5b is released from the convex portion 25, is sent by the disk 15, and is moved to the second stopper 2.
It comes into contact with the roller bearing edge 32 of No. 6 and is stopped.

Next, when the solenoid is de-energized and the second stopper 26 returns to its original position, the balloon guide 27 and first stopper 20 also return to their original positions as shown in FIG. 3 and are stopped at the roller bearing edge 32. The second carrier 5b, which had been
6 into the recess 31, that is, into the winding position 11. At the same time, the shaft 39 shown in FIG. 1 is rotated by a drive device (not shown) to open the valve 38, and compressed air is ejected from the nozzle 35 through the through hole 34 of the disc 15 and the through hole 10 of the peg 7, and the pipe is The yarn end Y of the yarn 4 is blown up and held by the suction pipe 41, and winding is started. At this time, the loading side passage 12
The third carrier 5c that was in the position a enters the standby position 24 instead of the second carrier 5b and moves to the first carrier 5c.
One of the carriers 5, which is stopped by the convex portion 25 of the stopper 20 and further transferred one after another on the tube supply conveyor 1, is guided into the carry-in passage 12a.

In the above-mentioned pipe yarn supply and discharge device 3, the winding position 11 of the carrier 5 is located on the disc 15 which is always passively rotated by the pipe yarn supply conveyor 1, and is therefore moved from the standby position 24 to the winding position 11. The carrier 5 is transferred quickly and reliably, so that the timing between the air jet from the nozzle 35 and the carrier transfer is not out of sync, and the yarn end Y of the pipe yarn 4 is reliably blown up by the air.

Further, the air is supplied to a through hole 34 provided in the disc 15.
Since the yarn is ejected linearly from the nozzle 35 to the through hole 10 of the peg 7 through the thread, the blowing up of the yarn end Y becomes even more reliable.

Further, the first carrier 5a and the second carrier 5b are always maintained in a non-contact manner, and the second carrier 5b is supplied to the winding position 11 at the same time as the discharge of the first carrier 5a is completed.

In other words, when the first carrier 5a is ejected, two
The second carrier 5b does not become an obstacle, and the first carrier 5a does not become an obstacle when the second carrier 5b is supplied.

As explained above, according to the present invention, the operation of supplying the pipe yarn to the winding position is ensured, and timing errors with the winding unit can be prevented and the winding operation can be performed smoothly.
