It is preferable that the upper brim of the bundling drum be provided with a slit into which the wire end clamp can interrupt.

Although the wire rod is not particularly limited, it is intended for a flat cable having directionality to bending. In this case, it is preferable that the wire rod end pinching mechanism be configured to pinch the flat face of the flat cable, and the wire rod end clamp be capable of holding the flat face of the flat cable.

[0009]

According to the automatic wire rod bundling device of the present invention,
When the end of the wire rod that comes out of the wire rod guide portion is grasped by the wire rod end clamp and moved forward, the end of the wire rod reaches the winding drum surface of the bundling drum, and it is possible to push it further deeper. Therefore, the end of the wire rod is inserted into the wire rod end pinching mechanism on the winding drum surface of the bundling drum and is pinched and fixed, so that it can be firmly fixed so as not to come off before and after winding start of the wire rod.

If the upper collar has a slit, the wire rod end clamp can be interrupted to more easily move the wire rod end to a deep position.

According to the present invention, even if a flat cable having directivity for bending is used as the wire rod, the above operation can be performed by gripping and sandwiching the flat surface, and twisting can be prevented. It can be wound on a flat surface without it.

The apparatus of this embodiment comprises a bundle apparatus for a flat cable as the wire rod 7. Therefore,
The "wire material" is replaced with a "flat cable" or simply "cable" in the description.

As shown by reference numeral 2 in FIG. 1, the bundling drum has a cable terminal clamping mechanism 3 capable of clamping and holding the flat cable 7 from the flat surface on the winding drum surface.
Is provided. Further, the upper collar 1 of the bundling drum 2 is provided with a slit 4 which reaches the cable end pinching mechanism on the winding drum surface.

Further, as shown in FIG. 2, the bundling drum 2
A cable end clamp 6 is provided at the flat cable passage portion between the cable guide 5 and the bundling drum 2 provided on the side of the. The cable end clamp 6 has two plate-shaped clamp portions capable of gripping the flat surface of the flat cable 7, and is linked to a drive mechanism (not shown) that makes a linear motion at the upper portion thereof. The cable guide 5 can be moved forward from the end to the bundling drum 2 and vice versa.
