Further, as the operating cylinder 26 is shortened and the base 30 is retreated together with the movable body 29, the pair of clip pieces 33, 33 are pulled out from the core R1 of the take-up reel R, and the guide pin 43, The guide holes 46, 46 of the base 30 are fitted into the tips of the bases 30, and the base 30 is positioned. Said clip piece 3
3 and 33 are completely removed from the core R1 of the take-up reel R, the presser cylinders 47 and 47 are shortened.
Furthermore, as the operating cylinder 26 is shortened, the cover plate 40 of the movable body 29 comes into contact with the slide shaft 38, and the slide shaft 38 is moved backward against the elasticity of the spring 39. Return to original state. After this, the turntable 11 of the wire winding machine is rotated, and the winding reel R is replaced with a new one.

In addition, in the above embodiment, the winding core R1 of the take-up reel R
Although an example is shown in which the take-up reel R can be automatically attached and detached from the winding core R1, it is also possible for the operator to attach and detach the take-up reel R to and from the winding core R1. Also,
Detecting the stop position of the base 30 by a detection means,
It is preferable to prevent malfunction of the operating cylinder 26.

(Effect of the invention) In other words, this invention has the above-mentioned "composition of the invention"
The gist is to sandwich the cylindrical winding core of the take-up reel through the opening hole of the flange of the take-up reel and position the clip pieces, which are a pair of two protruding from the base, inside and outside the core. Since the starting end of the wire material can be elastically held on the same winding core, there is no need to damage the starting end of the wire material on the winding core of the take-up reel when winding is started in the wire material winding machine. In addition, by releasing the above-mentioned holding after winding the wire material, the starting end of the wire material can be easily removed from the take-up reel when unwinding the wire material. I can do it.

In particular, according to the present invention, clip pieces made of a pair of leaf springs protruding in parallel from the base are positioned inside and outside the cylindrical core of the take-up reel, sandwiching the cylindrical core of the take-up reel. In particular, since the starting end of the wire material can be elastically held on the same winding core, the starting end of the wire material can be easily inserted into the winding core using the clip piece made of leaf spring material without bending it. In addition, the clip piece can be easily pulled out from the core even after the wire material has been wound up.
