Conventionally, when taking out a string bundle wound around a winding shaft, one of a pair of disks for determining the width of the winding bundle that was placed opposite to the winding shaft at a predetermined distance was placed on the winding shaft. Remove from
Since the wound bundle was then taken out from the winding shaft, it required a lot of work and had the disadvantage that it was difficult to take out the bundle.

The present invention has been made in view of the lack of conventional technology.
The purpose of this is to use a pair of opposing discs to determine the width of the bundle wound around the winding shaft. An object of the present invention is to provide a body winding device. Embodiments of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, A is a string rewinding machine, in which the string-like object a is paid out at a string unwinding section 31 that pulls and lets out the string-like object a from a drum 13 on which a large amount of string-like object a is wound. , a string guide (traverser 1) 15VC that reciprocates in the length direction of the winding body 14 allows the winding to be rewinded in an orderly manner. The winding device of the present invention is used in the rewinding section having the winding body 14, and its configuration will be explained below. As shown in FIG. 3, a driving shaft 1 driven by a motor (not shown) via an appropriate drive mechanism is mounted in a casing 16.
The power transmission case 41 is disposed in the upper part of the power transmission case 41 disposed on the front surface of the power transmission case 41. A flange 17 is attached to the tip of the drive shaft 1 by a set bolt 18VC, the drive shaft 1 is screwed to the flange 17, and a drive disk 2 is attached to the tip of the drive shaft 1. As shown in FIG. 4, the driving disk 2VC has twelve engaging holes 3 formed at equal intervals on the same circumference around the center of rotation. As shown in FIG. 5, a counterbore hole 19 having the same diameter as the engagement hole 3 is formed in the flange 17 at the same position as the engagement hole 3, and this counterbore hole 19 comes into contact with an engagement shaft 7, which will be described later. A holding shaft 4 is provided on the outside of the driving shaft 1 in a cantilevered manner and supported by a support frame 20 extending from a casing 16. The holding shaft 4 is separated from the driving shaft 1 by an appropriate distance,
It is supported substantially concentrically so that it cannot rotate. As shown in FIG. 6, a movable flange 22 is provided on the string diameter portion 21 at the tip of the holding shaft 4 so as to be rotatable and slidable but cannot be removed. The movable flange 22 can slide within the range of the stopper 23 of the C-ring and the shaft stepped portion 24. A clamping disk 5 is fixed to the movable flange 22 with a pin. As shown in FIG. 1, the clamping disc 5VC has six through holes 25 spaced at equal intervals in the circumferential direction on a circumference having the same diameter as the engaging hole 3, centered around the center of rotation. It is provided. The through hole 25 is formed in a potbellied shape consisting of a round hole 28 and a narrower elongated hole 26.
As shown in FIG. 8b, the moving flange 22 has a through hole 2.
A circular hole 27 having approximately the same diameter as the circular hole 28 of No. 5 is passed through. A recess 29 is formed in the circular hole 21 in communication with a portion of the moving flange 22 on the rotation center side. The recess 29 is the through hole 25
They are made to communicate with each other at the same shape and position as the elongated hole 26. A slide operating tool 6 is inserted into a portion of the holding shaft 4 that is outside the holding disk 5 so as to rotate and slide in the axial direction. On the drive disk 2 side of the slide operating tool 6, six engagement shafts 7 are spaced at equal intervals in the circumferential direction on a circumference having the same diameter as the circumference where the engagement holes 3 of the drive disk 2 are scattered. is provided protruding from the driving disk 2 side. The engagement shaft 7 is parallel to the holding shaft 4. The diameter of the engagement shaft 7 is made slightly smaller than the engagement hole 3 and the round hole 28 of the through hole 25. Each engagement shaft 7 passes through the circular hole 27 of the moving flange 22 and the through hole 25VC of the clamping disc 5. The distal end of the engagement shaft 7 is an engagement portion 8 that can be engaged with the engagement hole 3 . A pulling piece 9 is provided in a protruding manner near the engaging portion 8 and on the rotation center side of the slide operating tool 6. As shown in FIG.
is inserted into the engagement hole 3 of the driving disk 2, and as a result, the clamping disk 5 is inserted together with the driving disk 2 via the slide operation tool 6.
It is designed so that it can be driven and rotated. While the string-like body a pulled out from the drum 13 is guided by the string guide body 15 in this way, the outer center of rotation 91 of the six engagement shafts 7 is
The winding portion can be re-wound using the winding core portion 10. In the figure, 32 is a counter that can stop the motor to stop driving the drive shaft 1 and complete the winding when the set value of the winding length Vc and the detected value of the winding length match. It is. The operating structure of the slide operating tool 6 is as follows.

The slide operating tool 6VC has a circumferential groove 11 formed therein. The operating lever 12 is attached to a support frame 2 that supports the holding shaft 4.
It is pivoted so that it can swing freely at 0VC. An elliptical ring 33 is formed at the longitudinally intermediate portion of the operating lever 12 . The ring 33VC protrudes a bolt 34 to the inner side, and the bolt 34 is loosely inserted into the circumferential groove 11 of the slide operating tool 6, and by swinging the operating lever 12, the slide operating tool 6 is slid along the holding shaft 4. It is configured to be possible. According to such a configuration, as shown in FIG. 3a, after rewinding is performed with the holding disc 5 in close proximity to the driving disc 2 and the width is regulated by both discs, Figure 3 BVC. As shown, by swinging the operating lever 12 outward, the slide operating tool 6 is slid outward, and the engaging portion 8 of the engaging shaft 7 is pulled out from the engaging hole 3 of the driving disk 2. The engaging shaft 7 is separated from the driving disk 2, and by further swinging operation, the engaging shaft 7 is moved away from the driving disk 2 by a large distance, and the pulling piece 9 at the tip of the engaging shaft 7 moves toward the clamping disk. 5 long hole 26V
C, fits into the recess 29 of the moving flange 22 and comes into contact with the moving flange 22, thereby pulling the moving flange 22 with the pulling piece 9 and separating the clamping disk 5 from the driving disk 2, Thus, by removing the engaging shaft 7 serving as the winding core from the bundle b and widening the gap between the two discs, the bundle b can be dropped from between the two discs and taken out. 3
Reference numeral 5 designates a lock bar, which, as shown in FIG. 9, is pivotally connected to an extension piece 36 extending from the support frame 20 so as to be movable up and down, and has a notch 37 formed in its lower surface.

A pin 38 is provided at the lower part of the operating lever 12, and when the operating lever 12 is largely swung toward the driving disk 2, it is urged to rotate downward by a spring (not shown) or the like. By engaging the notch 37 of the lock bar 35, the operating lever 12 is prevented from swinging outward, that is, the clamping disc 5
The holding disc 5 is positioned close to the driving disc 2 to determine the width of the bundle b. In such a case, the inner surface of the slide operating tool 6 comes into contact with the outer end 39 of the moving flange 22,
The holding disc 5 is positioned. Reference numeral 40 denotes a receiving plate, whose upper end is inserted into the falling path of the bundle b, and whose lower end is inclined downwardly so that the fallen bundle b can be rolled and taken out.

The drive disk 2 and the clamping disk 5 are made of vinyl chloride resin, which reduces the driving load due to their weight reduction, and although they are lightweight plates, the inner winding width regulating surface is made into a flat surface compared to a means of providing ribs made of sheet metal. This is what I did.

In the embodiment, 12 engagement holes 3 are provided in the driving disk 2VC, and 6 engagement shafts 7 are provided in the slide operating tool 6.
In order to engage the six engagement shafts 7 with the engagement holes 3vc, it was possible to match the phase with the engagement holes 3 by simply rotating the slide operating tool 6 slightly. 3 and the number of engaging shafts 7 can be changed.

In summary, the present invention is capable of reliably determining the width of a string bundle using a driving disk and a clamping disk and winding the string bundle, but by operating a slide operating tool, a plurality of string bundles can be wound to form a wound body. At the same time, in order to operate the slide operating tool beyond a certain level, the engaging shaft of the engaging shaft is pulled out from the driving disk, and the holding disk is pulled away from the driving disk by pulling the holding disk with a pulling piece provided on the engaging shaft. As a result, the bundle between the driving disc and the clamping disc can be dropped from between the two discs without any change, which is an improvement over the conventional method of removing the clamping disc from the winding shaft and extracting the bundle from the winding shaft. It has the advantage that the bundle can be easily removed.
