Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to solve the following problems.

(Industrial Field of Application) The present invention relates to a method for winding thread around a beam in which a large number of threads are wound around the winding shaft of a beam in a beam machine.

(Prior art) In a conventional beam machine, a press roll is elastically pressed against the outer periphery of the thread wound around the thread winding shaft of the beam by a cylinder or the like, and then the thread is pressed against the thread winding shaft of the beam. Since the thread is wound around the beam, even if the number of turns of the thread is the same around the thread winding shaft of the beam, the winding diameter and winding length of the thread wound around the thread winding shaft cannot be changed. I couldn't make it the same. For this reason, thread winding around the beam has been carried out by simultaneously and parallelly winding the thread over the entire range of the thread winding axis of the beam. However, with this method of simultaneously and parallelly threading the yarn around the beam winding axis, if the length of the beam winding axis is long, a large partial warping machine is required, resulting in high equipment costs. There is a problem,
It has been difficult to increase the length of the shaft around which the beam is wound. Therefore, if you want to increase the number of threads that can be pulled out from a beam, you can do this by installing multiple beams with short winding shafts in parallel and pulling out threads from these multiple beams. There was a problem that required a complicated device to equalize the thread tension of the threads drawn from the beam.

(Problems to be Solved by the Invention) This invention eliminates the above conventional problems and makes it possible to easily wind yarn around the beam winding shaft even when the length of the beam winding shaft is increased. Moreover, it is an object of the present invention to provide a method for winding thread around a beam, which allows the thread to be wound around the thread winding shaft the same number of times and with the same winding diameter.

The configuration of the present invention is as follows.

(Means for Solving the Problems) The present invention takes the measures as described in the claims above, and its effects are as follows.

(Function) When the thread winding shaft of the beam is divided by a separator to form a plurality of unit thread winding parts, and the thread is sequentially wound on each of these unit thread winding parts, and when the thread is wound on these unit thread winding parts. , a press roll is pressed against the outer periphery of the thread wound around the unit thread winding part, the press roll is moved away from the unit thread winding part at a predetermined ratio in accordance with the rotation of the beam, and the thread is applied to each unit thread winding part. winding the same number of turns and the same diameter.

In the case of the above structure, the beam 19 has a thread a
When winding the beam, the beam 19 is first attached to the support parts 20 and 21 of the beam machine as shown by the imaginary lines in FIG. 1, and the beam 19 is rotatably supported by the support arms 17 and 18. Also, the locking lever 11 of the locking means 9 is raised, and the press roll device 40
As shown in FIG. 8, the press roll 53 is moved to the rear of the outer diameter position of the beam 19, and in this state, the moving motor 6 is rotationally driven to rotate the wheels 2, and the frame 1 of the beam machine is moved to the rail. 4. As shown in FIG. 7, the frame 1 is moved by stopping the moving motor 6 by automatic or manual switch operation at a position where the space between one side plate 19c of the beam 19 and the separator 19c faces the press roll 53. By this or by subsequent adjustment, the press roll 5 is stopped between the side plate 19b and the separator 19c.

The size between c and 19c is adjusted in advance or each time to the same size as the length of the press roll 53 of the press roll device 40. Next, the clutch 75 of the press roll moving device 54 is disengaged, and the return motor 96 is rotationally driven with the clutch 95 engaged. As a result, the drive shaft 97 rotates to reversely rotate the chain wheel 98, chain 99, chain wheel 94, and intermediate shaft 67 in the direction of arrow B. This rotating shaft 6
For reverse rotation of 7, chain wheel 70, chain 72, chain wheel 6
6. It is transmitted to the cylindrical body 56 via the rotating shaft 64 and the bevel gears 65, 57, and rotates the cylindrical body 56 in the direction of arrow N. Therefore, the rotation of this cylinder 56 moves the screw shafts 62, 62 forward,
Slide the support arms 45, 45 forward. By the forward movement of the support arms 45, 45, the support arms 4
5, 45 and the press roll 53 enter between the side plate 19b of the beam 19 and the separator 19c, and then, as shown in FIG. Means is actuated to stop the return motor 96. The clutch 95 is then disengaged. Further, the handle 14 of the locking means 9 is rotated in one direction to lower the locking rod 11, and the lower end of the locking rod 11 is brought into contact with the rail 4 to fix the frame 1. The attachment of the beam 19 to the supports 20 and 21 is carried out with the frame 1 of the beam machine moved to a predetermined corresponding position and with the press roll 53 positioned at the forward end as shown in FIG. It's good to wear. Next, a large number of threads (for example, 500 threads) to be wound around the beam 19 are pulled out from a drum machine or the like and passed through the reel 38, and then, as shown in FIG. It is guided by the outer periphery of the tension roller 33 and the guide roller 30, and is tied to the thread-wrapped portion 19a of the beam 19, and then wound around the thread-wound portion 19a. As shown in FIG. 1, the thread a is wound around the thread winding portion 19a by guiding the thread a to the side opposite to the press roll 53 and winding it in a clockwise direction. You may also guide it to the side and wrap it counterclockwise.

Next, with the clutches 24 and 75 disengaged, the drive motor 26 is driven to rotate, which causes the drive shaft 26a to rotate, and the chain wheel 27 and chain 2
8. Rotate the chain wheel 25 and rotating shaft 23 in one direction (clockwise in FIG. 1). Due to the rotation of this rotating shaft 23, the chain wheel 92, chain 93,
The transmission shaft 85 rotates in the direction of the arrow via the chain wheel 91. The rotation of the transmission shaft 85 is transmitted to the input shaft 78 via the chain wheel 91, chain 90, and chain wheel 84.
The rotation of the input shaft 78 is changed to a predetermined ratio by the transmission 77 and transmitted to the output shaft 74, whereby the output shaft 74 is rotated at a predetermined speed in the direction of arrow A. Next, the clutches 24 and 75 are engaged simultaneously. As a result, one of the support parts 20 supporting the beam 19 is rotated by the rotating shaft 23, and the beam 19 is rotated in the same direction. This rotation of the beam 19 causes the thread a to be wound around the thread wrapping portion 19a between the side plate 19b and the separator 19c. In this case, the press roll 53 parallel to the thread wrapping part 19a is pressed over the entire width of the outer periphery of the thread a wound around the thread wrapping part 19a, so that the thread a is rolled as shown in FIG. The thread is wound neatly around the thread winding portion 19a between the side plate 19b and the separator 19c. On the other hand, the rotation of the output shaft 74 is transmitted to the intermediate shaft 67 by the engagement of the clutch 75,
This rotation of the intermediate shaft 67 causes the chain wheel 70 and the chain 7
2. Chain wheel 66, rotating shaft 64 and bevel gears 65, 5
7 to the cylindrical body 56, and rotates the cylindrical body 56 in the direction of arrow C. Therefore, this cylinder 56
The screw shafts 62, 62 are moved rearward by the rotation of the press roll 53, whereby the support arms 45, 45 are slid rearward, and the press roll 53 is moved backward.
This backward movement of the press roll 53 is performed at a predetermined ratio determined by the type and count of the yarn a to be wound around the beam 19 in accordance with the number of rotations of the beam 19. That is, the press roll 53 is gradually moved backward at a predetermined ratio in accordance with the number of windings of the yarn a wound around the beam 19. The retreating speed of the press roll 53 is set so as not to be significantly different from the increasing speed of the winding radius of the yarn a wound around the yarn winding portion 19a, so that the press roll 53 always maintains a state in which it presses the outer periphery of the wound yarn. do. Therefore, this press roll 53 determines the winding diameter of the thread a currently wound around the thread winding portion 19a. Winding the yarn a around the beam 19 and press roll 53
The retreat is caused by the clutches 24 and 75 being disengaged when the thread a has been wound around the thread winding portion 19a a predetermined number of times to such an extent that the winding diameter of the thread a is close to the outer diameter of the beam 19. will be stopped. At this point, the distance between the press roll 53 and the thread winding section 19a, that is, the winding radius of the thread a wound around the thread winding section 19a, is a predetermined value corresponding to the number of windings of the thread a wound around the beam 19. It's going to be.

Next, by engaging only the clutch 75 for a while, the press roll 53 is further moved slightly rearward, and the press roll 53 is moved further rearward than the outer diameter position of the beam 19, as shown in FIG. At this position, the clutch 75 is disengaged to stop the press roll 53. Next, after releasing the fixation of the frame 1 by the locking means 9 again as described above, the moving motor 6 is rotationally driven to move the frame 1 by a predetermined amount to the right as shown in FIG. Separates 19c, 19c adjacent to the thread-wrapping area are opposed to the press roll 53. Thereafter, the return motor 96 is driven to rotate in the same manner as described above to move the press roll 53 forward between the separate plates 19c, 19c. Thereafter, by repeating the above operation, the beam 19
As shown in FIG. 9, the yarn a is sequentially wound around the yarn wrapping portion 19a between the side plate 19b and the separator 19c and between the separators 19c and 19c, and finally all the yarn wrapping areas that are divided into a plurality of yarn wrapping areas are wound. Thread a
Wrap around. In this case, the number of times the yarn a is wound around each yarn wrapping area is made equal. As a result, the winding diameter of the yarn a wound in each yarn winding area becomes the same due to the action of the press roll 53 as described above.

That is, the thread winding portion 19a between the side plate 19b and the separator 19c in the beam 19 and the separator 19
The thread a can be wound with the same number of windings and with the same winding diameter in the same way as when thread a is wound simultaneously and in parallel around the thread winding portion 19a between the two threads. The lengths of the threads a wound around the portion 19a can be made approximately the same. In the case of the beam 19 in which the yarn a is wound around each yarn winding portion 19a the same number of times and with the same winding diameter, all the yarns a are simultaneously pulled out from the beam 19 in the subsequent processing step. When unwinding the yarn by simply rotating the beam 19 back, the thread tension of each unwinding thread a can be made approximately the same, and the unwinding operation of the thread a can be performed well. The device can be simplified. Furthermore, since the length of the thread a wound around each thread winding part 19a can be made approximately the same as described above, when the thread a is unwound from the beam 19, the amount of residual thread remaining in each thread winding part 19a can be reduced. It is economical. Furthermore, even if the thread a is wound around each thread winding part 19a as described above, each thread winding part 19a can be wound with the same number of windings and with the same winding diameter. Even when the length of the shaft 19a' is long, the shaft 19 with which the thread is wound
By winding the thread a around each thread winding portion 19a formed on the thread a', the thread winding shaft 1 of the beam 19 is
The thread a can be easily wound around the thread 9' with the same number of windings and with the same winding diameter. Furthermore, by winding the thread a around each thread winding section 19a as described above, the thread a pulled out from the creel can be directly wound around each thread winding section 19a, and the thread a drawn out from the creel can be directly wound around each thread winding section 19a. The work of winding the thread a around the long beam 19 can be simplified.

(Effects of the Invention) As described above, in the present invention, when threads are wound around the thread winding shaft of the beam, the ends of a large number of threads are fixed to one of the unit thread winding parts, and the end portions of the threads are kept in that state. By rotating the beam in one direction, the thread can be wound a predetermined number of times around that unit thread winding section, and then the thread can be wound a predetermined number of times around the remaining unit thread winding sections in the same manner as above. Therefore, the yarn can be wound a predetermined number of times around the yarn winding shaft of the beam. This results in
Even if the length of the beam winding shaft is increased, the thread can be easily wrapped around the thread winding section in each unit of short length. There are practical effects that can be easily provided.

In addition, when winding the thread around the unit thread winding section as described above, a press roll that is pressed against the outer periphery of the thread wound around the unit thread winding section is moved from the unit thread winding section at a predetermined ratio to the rotation of the beam. This makes it possible to set the outer diameter of the thread wound around the unit thread winding part to a size corresponding to the number of times the thread is wound around the unit thread winding part. Therefore, even when thread is wound sequentially around a plurality of unit thread winding parts as described above, by making the number of windings of the thread around each unit thread winding part and the retraction ratio of the press roll the same. As a result, it is possible to wind the yarn with the same number of windings and with the same winding diameter, just as if the yarn were wound simultaneously and parallel to all the unit yarn winding portions. In this way, yarn can be wound around multiple unit yarn winding sections with the same number of windings and with the same winding diameter, making it possible to simultaneously pull out all the yarns wound around the yarn winding shaft of the beam in the post-processing process. When unwinding the yarn, by simply returning and rotating the beam, the yarn tensions of all the yarns can be easily made to be approximately the same, and the yarn unwinding operation can be performed satisfactorily.
