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

(Industrial Application Field) This invention relates to the outer periphery of a yarn wound around a beam (including a drum, etc.) in a beam machine, a partial warper, a rough warper, etc. (hereinafter collectively referred to as a beam machine, etc.). The present invention relates to a press roll device that is adapted to press the press roll.

(Prior art) In the conventional press roll device of this type,
A press roll is pressed against the outer periphery of the thread wrapped around the beam with a predetermined pressure using a cylinder, etc., and the thread is wound around the beam while the thread wrapped around the beam is always pressed with a predetermined force. Therefore, even if the number of rotations for winding the beams is constant, the outer diameter of the yarn wound around each beam and the length of the yarn wound around each beam are not uniform. Therefore, when unwinding yarn from multiple beams in parallel, a complicated device is required to keep the tension of each yarn approximately constant, which increases equipment costs, and the length of the remaining yarn on each beam increases. There was a problem with large variations and a lot of waste.

(Problems to be Solved by the Invention) This invention makes it possible to make the winding diameter of the thread wound around the beam correspond to the number of rotations of the beam, and to make the number of windings of the thread around the beam the same. Therefore, it is an object of the present invention to provide a press roll device for a beam machine or the like in which the outer diameter dimension of the yarn wound around each beam and the amount (length) of the yarn wrapped around each beam can be made substantially constant.

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) The function of the present invention is that when a thread is wound around the thread winding part of the beam, a press roll contacts the outer periphery of the thread wound around the thread winding part and presses the wound thread,

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.
3 is exactly opposite. Note that between the side plate 19b of the beam 19 and the separator 19c, and between the separator 19
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 cylinder body 56 via the rotation shaft 64 and bevel gears 65, 57, and rotates the cylinder body 56 in the direction of arrow D. 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. 2, 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.
The yarn a may be guided to the press roll 53 side and wound 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. 2). 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 is wound around the yarn winding portion 19a at that point. Determine the winding diameter of yarn a. Winding the yarn a around the beam 19 and press roll 5
3 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. It 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 rearward beyond the outer diameter position of the beam 19, as shown in FIG. ,
At this position, the clutch 75 is released 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. A press roll 53 is placed between the separators 19c and 19c adjacent to the thread-wrapped area. After that, the return motor 9 is operated in the same manner as above.
6 is rotated to move the press roll 53 forward between the separators 19c and 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.

Note that in the above embodiment, the press roll 53
The length of the press roll 53 is made significantly shorter than the length of the beam 19, and the beam 19 is provided with a separator 19c. It is also possible to wrap the yarn at once around a conventionally known beam that does not have a separator 19c, and in this case, the frame of the beam machine may be fixedly installed.

(Effect of the invention) As described above, in this invention, the beam 19
When winding the yarn a around the thread a, the beam 19 is supported by the support parts 20 and 21, and the beam 19 is rotated by a drive device, so that the thread can be wound around the thread winding part 19a of the beam 19. This makes it convenient to use the beam around which the yarn is wound for weaving.

When winding the thread a around the beam 19, the press roll 53 parallel to the thread winding part 19a of the beam 19 contacts and presses the outer periphery of the thread wound around the thread winding part 19a. A large number of threads can be wound in an orderly manner, and the threads can be unwinded in a subsequent process.

In addition, when winding the yarn around the beam 19 as described above, the press roll 53 that presses the yarn in contact with the outer periphery of the yarn wound on the yarn winding section is pressed at a constant ratio to the rotation of the beam 19 to wind the yarn around the beam 19. Attached part 1
9a, thereby making it possible to set the outer diameter of the thread wound around the thread winding portion of the beam to a dimension corresponding to the rotational speed of the beam. Therefore, when winding yarn around multiple beams one after another, by setting the thread winding rotation speed of the beams at a constant value in advance, the finished outer diameter of the yarn wound around each beam can be made approximately constant. . As a result, when threads are unwound in parallel from multiple beams, by simply pulling out each thread, the number of rotations of those beams and the tension of each unwinding thread can be kept approximately constant, which has the effect of simplifying the post-processing process. .
