DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for arranging a plurality of tied members such as strings or ropes in parallel in the longitudinal direction and winding the tied yarn at an arbitrary position on the tied member. The present invention relates to a technique for preventing a knot of a binding yarn from being disturbed.

[0002]

2. Description of the Related Art Conventionally, two or more strings or ropes are arranged in parallel in a longitudinal direction, and the plurality of strings or ropes are mechanically bound at regular intervals by a binding thread. For example, Japanese Patent Application Laid-Open No. 6-62709. This technique makes the first loop by tying the binding thread along the rope and hooking the binding thread at the binding position.
This was wrapped around a rope, and then a second loop was made. The first loop was passed through the second loop, and the starting end was pulled to bind it.

[0003]

However, the above-mentioned technique can be bound in principle. However, when a binding thread is hooked and wound around a binding rotary piece and then removed, or when a threading rod is removed, It was difficult to keep the binding yarn loose, and it was difficult to make it a realistic binding machine. In view of this, the present applicant has proposed, in Japanese Patent Application No. 8-98038, a technique of arranging two or more ropes in parallel in a longitudinal direction and binding the plurality of ropes with a binding yarn. However, when tying the thread wound on the rope to make a knot, it was sometimes difficult to tighten. That is, when the binding thread is removed from the thread hook, the binding thread is loosened and the binding thread is disturbed, so that the binding thread may be in a state of being easily unwound even when tightened.

[0004]

The problem to be solved by the present invention is as described above. Next, means for solving the above problem will be described. That is, the yarn hook is disposed at the binding position of the tied member so as to be able to advance and retreat, the tied yarn is aligned around the tied member and the yarn hook and wound a plurality of times, and the tied-off member removes the tied yarn from the yarn hook. In a configuration in which both ends of a binding yarn are pulled to form a knot and tightened, a plurality of bar guides are formed so as to be parallel to the member to be bound, and a thread guide is projected from the thread removing member. It is configured to protrude from the thread hook, remove the binding thread wound on the thread hook, temporarily hold the thread on the thread guide, and then remove the binding thread from the thread guide while tightening to bind the thread.

23, the pawl 67 is inserted in the open state from the space between the thread hook 9 and the rope as shown in FIG. 23, and at the same time, as shown in FIG. 14, FIG. The pulling member 22 slides rightward to remove the binding yarn 1 wound on the yarn hook 9 and drop it on the yarn hooking portions 48b of the yarn guide 48, and the tip of the claw 67 is attached to the binding yarn 1a. At a position past the position, the stopper comes into contact with the stopper 78, the claw body 67 is closed, and the binding thread 1 is locked. Second thread tightening section K
The claw body is also raised in the open state at the same time, and the tip abuts on the stopper at a position beyond the position of the binding yarn 1a, and the claw body is closed to lock the binding yarn 1.

Further, by the rotation of the motor M2, the sliding body of the second thread tightening section K slides downward, and the sliding body 65 of the first thread tightening section J slides leftward. The binding thread 1 is removed from the thread guide 48, and as shown in FIGS. 25 and 26, the pawl body 63 of the second thread tightening section K is moved downward, and the pawl body 67 of the first thread tightening section J is moved downward. Are simultaneously moved to the left, the binding yarns 1 are pulled to both sides of the knot, tightened and bound, and the claws 63 and 67 are opened to remove the binding yarns 1. At this time, the pressing member 21 moves to the left by the rotation of the control cam 91 and returns to the original position. When the control cam 35 is rotated to the work start position, the starting point is detected by the sensor S2 and the motor M
2 is stopped.

In this manner, the binding operation is completed, and the excess binding yarn is cut with a cutter or the like, and is removed from the clamp devices A and B, whereby one knot is completed. When working further after the binding, the knot is clamped to the clamp devices A and B in accordance with the scale position on the rail 123 indicating the desired knot interval, and the lock R is released. The binding thread 1 is pulled out to the left, the length is set with the scale plate 130, and the operation switch 132 is pressed in the same manner as described above to repeat the binding operation.

[0044]

As described above, the present invention has the following advantages. That is, as in claim 1,
A thread guide in which a plurality of rod-shaped members are configured to be parallel to the members to be bound is projected from the thread removing member, and the thread guide is positioned inside the thread hook and protrudes from the thread hook at the time of bundling, and is tied around the thread hook. Remove the thread and hold it on the thread guide once,
It is configured so that the binding yarn is removed from the yarn guide while tightening, so that when removing the binding yarn wound around the thread hook,
If dropped directly onto the claw body, the binding yarn is loosened due to the large space between the thread hook and the claw body, and the aligned binding yarn is disturbed, but once dropped onto the thread guide and removed while tightening The knot could be reliably tied in place without loosening and disturbing, and the knot could be tied to the hard-to-release knot. The thread guide can be easily manufactured with a rod-shaped body, for example, a wire, and can be obtained at low cost.
