Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Application of N Toue The present invention is applicable to the case where a flexible rod is forcibly moved forward and backward by a feeding device to feed out a binding string to a string hole of a needle and thread the string through it. A string threading device for a tying machine that has been improved so that the braking state of the brake device can be released by a single operation of operating the feeding device, and the string slack removing rod can be aligned with the flexible rod passage path at the same time. Regarding.

(b) In the conventional tying machine, before starting the tying work, the tying string pulled out from the first string is inserted through the string brake device, the string slack removing lever and the guide pipe into the string hole at the tip of the needle, and the knot is inserted into the string hole at the tip of the needle. It is necessary to make preparations to hold the cable in place, but the feeding path for the cable tie is usually arranged in such a way that it weaves between the small parts where various mechanisms are intricately connected. When threading the laces manually, it is very difficult and time-consuming, and because of the difficulty of the work, it is easy to make mistakes when threading the laces, and the tying process may start without realizing that the laces have been threaded incorrectly. This often results in a situation where a mistake is made in bundling. For this reason, recently, for example, Japanese Utility Model Publication No. 59-33234 and Japanese Unexamined Patent Publication No. 6
As seen in Publication No. 1-60413, etc., a binding cord is locked to a string threading body that moves forward and backward along a string feeding path, and the string is threaded through the string feeding path by the advancing movement of the string feeding body. A labor-saving device for string threading has been proposed.

(c) Problems to be solved by the invention By the way, in the middle of the string payout path in the tying machine, there is a string brake device and a string slack removing spring device for applying appropriate tension to the string being fed out. (referred to as a string slack removing rod) is indispensable. The string must pass through the string brake device and the string slack-removal lever, but in the existing proposal, the operator first manually changes and maintains the string brake device in the brake-released state, and then removes the string slack-removal lever. Move the string threader to the passing position and fix it, then move the string threader to the feeding path and thread the string, and after the string threading is finished Y and the string threader moves forward from the feeding path. In addition, the structure requires manual action to return the string brake device to the braking state and return the string slack removing lever to its original position.

Therefore, although the existing levee proposal saves some work in that the string can be threaded through the feeding route by moving the string threading body that locks the tie string back and forth, it is possible to save some labor when threading the string. The operation of releasing the brake of the cord brake device and the operation of changing the position of the cord slack removing lever still have to be done manually, so the degree of labor saving is insufficient. This can cause damage to the string threading body, string brake device, etc., or if you forget to return the string brake device or string slack removing rod to the original position after finishing string threading, and start the work afterwards, an accident may occur. There are still some easy problems.

Therefore, the present invention was carried out with the aim of providing an automatic lace threading device that eliminates all of the above-mentioned problems.When the lace is automatically inserted into the lace delivery path, the lace braking device is released and the lace is loosened. The present invention provides an improved device in which the position of the handle is automatically moved.

As a matter of course, the release of the brake by pushing down the brake plate (23b) and the movement of the string slack removing lever (24) into the notch (39) of the ring part (24a) are caused by the flexibility during the unwinding. The paper damage protrusion (19) on the rod (18) is the brake device! (23) and before reaching the slack removing rod (24), the flexible rod (18) is fed out and extended.
) passes through the brake device (23) in the released state, passes through the ring part (24a), and then passes through the guide pipe (22).
It is extended through the needle (5) and stops when it passes through the string hole at the tip of the needle (5).

After this condition is reached, the operator should press the needle (5)
Remove the binding string (M) that has passed through the string hole at the tip, and
The hook is set as shown in the figure. 5 Figure 8 shows the string set at the knot, and the needle (5)
The binding string (M) that has passed through is hooked to the paper damage prevention piece (4o) fixed to the right end of the knot cover (1) for accurate positioning, and the end is used to drive the east release arm (4) in the stored state. Hook it onto the paper scratch prevention piece (41) installed on the crank arm. Then, when the door/clutch actuating body (6) is pulled to engage the clutch and the clutch is activated in an empty state, the needle (5)
) creates a state in which the binding string (M) is held in the knot building (2) and the string holder (3), and then the pieces of the binding string (M) cut by the string cutting blade are released into bundles. Since the arm (4) is rotated, the cord is pulled in by hand, and the threading operation is completed by removing it from the paper scratch prevention piece (41).

In addition, the flexible rod (18) when threading the string passes through the released string brake device (23) and the ring part (24a) of the string slack removing rod (24), and then continues to touch the tip of the needle. The karari coil handle (which must be extended towards the string hole)
12) continues to be pulled, and accordingly, the guide wheel (32) continues to rotate even after the interlocking arm (30) reaches the operating position shown in FIG.

For this rotation, the tip of the interlocking arm (30) fits into the spiral groove (34) on the outer periphery of the wheel body (32), and moves along the spiral groove (34) from the position shown in FIG.
Since the flexible rod (18) moves to the position shown in the figure and responds, there is no problem in continuing to feed out the flexible rod (18).
) After the entire process of unwinding is completed, if the pulling force applied to the recoil handle (12) is removed, the recoil rope (12a) is wound back and the flexible rod (18) is released. As it is pulled back into the storage pipe (20), the interlocking arm (3o) makes a flexural movement along the spiral groove (34), returning from the state shown in FIG. 5 to the state shown in FIG. 3, contrary to the above. And the flexible rod (1
8) has completely passed through the ring part (24a) and the released string brake device (23), the interlocking arm (30) moves from the operating position shown in FIG. 6 to the fourth position around the brake roller shaft (27). It will return to its original position as shown in the figure,
The brake system fl (23) returns to the braking state, and the slack-removal rod (24) also returns to the slack-removal position displaced laterally from the guide pipe (22), and the tied string (M ) to apply the desired braking force and to take up the slack.

(g) Effects of the invention As explained above, the present invention has a string brake device (23
) An actuating arm (36) is installed on a support shaft (27) to which a brake release mechanism (38) and a string slack removing lever (24) are pivotally connected, and the actuating arm (36) is attached to the fulcrum of the pivot shaft (29). The elongated hole (35) is engaged with the swinging interlocking arm (30), and the interlocking arm (30) is engaged with the elongated hole (35).
The guide portion (32) of the guide body (32) is fitted with the tip end of the guide member (30) to the glue coil shaft (15) for advancing and retracting the flexible rod (18).
