[Promise of invention] 1

【【Five Δ Breasts Public Body】 The present invention relates to a press roll device in a beam warp machine, etc., which presses warp threads wound around a beam or the like. l Mi Shaoji Street Conventionally, in a press roll device for a beam machine, etc., the warp threads to be wound around the beam are wound while being pressed by a press roll with a predetermined pressing force. Since it is fixedly attached above the beam, the outer diameter of the warp wound around the beam expands, and the starting end of the winding moves sequentially, thereby constantly pressing the starting end of the winding with a press roll. As a result, the outer diameter and length of the warp threads wound around the beam become uneven, and a complicated device is required to maintain warp tension at a constant level during the subsequent unwinding process. As a result, the equipment cost is high, and the length of the remaining yarn in the beam varies widely, resulting in a large amount of waste. , l] is Ll. The present invention uses a simple mechanism to uniformly wind the warp yarns in the same state at all times, making it possible to unwind them in the next process, and keeping the outer diameter of the warp yarns wound around the beam approximately constant, so that multiple warp yarns can be wound evenly in the same state. The present invention aims to provide a press roll device for a beam machine, etc., which simplifies the post-processing device because it can equalize the rotation of the beam and the tension of the unwinding yarn when unwinding from the beam. be.

A large number of warp threads w to be wound around the beam 6 are pulled out from a drum machine or the like (not shown), and the roll 35 is pulled out from the drum machine or the like (not shown). 35a1 is attached to the beam 6 via the guide roll 27, and the cylinder 24.24a of the press roll drive device 14 is actuated to move the moving table 19.19a.
is moved forward toward the beam 6 side, and the foot roll J5, which is rotatably supported by the support arm 21.21a attached to the support plate 20 of the moving table 19.19a, is applied to the outer periphery of the beam 6 (spool surface) with a predetermined pressure. When the pressed state is established, the motor 32 of the guide roll driving device = 26 is activated to rotate the screw shaft 28.28a, and the screw shaft 2B, 2
8a is advanced toward the beam 6 side, and the guide roll 27, which is rotatably supported by the bracket 34.34a, is moved so that the pressing position of the press roll 15 is at the starting end of the winding of the warp threads W. Move it forward to the position A to complete the preparation for winding. Thereafter, by activating the motor 13 of the beam drive device 7 and rotating the beam 6 in a certain direction, the warp threads W are wound around the beam 6, and the winding diameter gradually increases depending on the state of the winding. As the diameter increases, the press roll driving device π14 winds the press roll 15 around the beam 6 in accordance with the rotational speed of the beam 6 while maintaining the pressing state at a predetermined ratio determined by the type and count of the warp yarn W. At the same time, the guide roll 27 is moved backward by the guide roll drive device 2 at a predetermined setting ratio in the same way as the press roll 15 so that the winding start end portion A substantially coincides with the pressing position of the press roll 15.
By moving the raft backward at step 6, the wire is always wound uniformly in the same state. [Effects of the Invention] In short, the present invention rotates the beam 6 and rotates the beam 6.
In a beam machine, etc., which has a press roll 15 whose movement is controlled according to the winding diameter while pressing the winding surface of the warp W to be wound, the warp W is moved to a position where the winding surface of the press roll 15 is pressed. The movement of the guide roll 27 that guides the warp yarns W is controlled so that the winding start end A of the warp threads W is almost coincident with the winding start end A of the warp threads W, so that even if the winding diameter changes, by always pressing the winding start end A, the winding start end A can be kept uniform in the same state. The warp threads W wound around the beam 6 can be unwinded in the next step without any problems, and the finished outer dimensions of the warp threads W wound around the beam 6 can be kept approximately constant. When unwinding the warp threads W from the beams 6 in parallel, these beams 6 can be unwound by simply pulling them out.
Since the rotation of the thread and the tension of the unwinding thread can be made uniform, the equipment for post-processing can be simplified, and since it is a simple mechanism, it is possible to make slight improvements to existing equipment, making it possible to use it effectively. Its practical effects are enormous, such as being able to
