Accordingly, the insertion part 32 and the guide roll 36 mounted on the upper surface of the rotating plate 34 are also rotated in the same manner, and the rotating plate 34 has the strap member S1 of the strap S being released. It is rotated in the same rotation direction as the release direction.

Here, the tip of the strap member S 1 of the strap S inserted into the insertion part 32 is a guide case of the guide part 50 provided between the main body part 30 and the bending machine 101 ( 51 is supplied to the bending machine 101 side.

That is, by rotating the horizontal axis 54 by driving the feeding motor 53 installed in the guide case 51 to rotate the feeding wheel 52 assembled therein in one direction, the pin member 52 mounted on the outer peripheral surface is It is inserted into the through hole (S2) of the string member (S1) entered into the inner space through the guide roll 57 of the guide case 51 and smoothly guides the string member (S1) to the outlet side without generating a friction force. .

The suction motor 55 disposed above the feeding wheel 52 while guiding the strap member S1 of the strap S by the rotation driving force of the feeding wheel 52 to the bending machine 101 side. To generate suction force at the front end of the suction port 55a, and remove the foreign matter adhering to the surface of the string member S1 by the generated suction force, and the suctioned foreign matter is collected in the dust collecting case 56 and is post-processed. .

On the other hand, when the rear end of the strap member S1 of the preceding strap S is close to the upper and lower clamps 58, the driving of the feeding motor 52 is temporarily suspended, and a new trailing path is newly entered into the guide case 51. The upper clamp is lowered with respect to the lower clamp fixed to the bottom surface of the guide case 51 in a state where the front end of the string member S1 of the strap S and the rear end of the string member S1 of the preceding strap S overlap each other. Activate to bite the overlapping part of the string member of the line and trailing strap.

In this state, the spot welder 59 disposed at the front end side of the upper and lower clamps 58 is operated to weld the overlapping portions of the line and the following straps to each other. When the welding connection work by the spot welder 59 is finished, the feeding motor 53 is restarted to continuously supply the string member S1 to the bending machine 101.

In addition, the overlapping state and the welding state of the line and trailing straps S can be easily observed by the operator through the cover member 51a made of a transparent material.

According to the present invention as described above, before all the strap members of the preceding strap is exhausted, a new strap can be supplied easily and quickly, the preceding strap member and the trailing strap member are superimposed and welded together, and the one-way strap and feeding Since the friction between wheels can be minimized, it is possible to replace the straps more easily than in the past, reduce the work time, improve the productivity of the work, and reduce the amount of straps generated, thereby reducing the manufacturing cost. .
