[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine in a wire drawing process.

[0002]

2. Description of the Related Art Generally, a winding machine in a wire drawing process is configured as shown in FIG. That is, a lifter 1 is installed between a pair of facing frame structures of a winding machine (not shown), a bobbin 2A for winding is mounted on the lifter 1, and a shaft hole of the bobbin 2A is moved by lifting and lowering of the lifter 1. The pintle 3 is provided on the frame (not shown) and is moved forward and backward with respect to the bobbin 2A. Here, the pintle 3 is advanced and inserted into the shaft hole, and the bobbin 2A is driven by the rotation of the pintle 3. The drawn wire is wound on the bobbin 2A.

[0003]

FIG. 5 shows a case where a wire is wound around a large bobbin (hereinafter, large bobbin) 2A. As shown in FIG. 6, a small bobbin (hereinafter, small bobbin) 2B is used. , It is necessary to raise the lifter 1 greatly and also to protrude the pintle 3 greatly.

[0004] Depending on the size difference between the large bobbin 2A and the small bobbin 2B, it is difficult for the lifter 1 to handle both bobbins. For example, large bobbin 2
When the diameter of A is 1300 mm, its axial length is 800 mm, and the diameter of the small bobbin 2B is 650 mm and its axial length is 400 mm, the stroke difference of the hydraulic cylinder driving the pintle 3 becomes 400 mm, and the lifter 1 Has a stroke difference of 325 mm.

[0005] As described above, if a single winding machine having a large stroke is used to take up a large or small bobbin that requires a large stroke difference for driving the pintle and lifter, respectively. The drive mechanism for the pintle and lifter is a very large and expensive device.

Heretofore, the following has been performed as a means for handling a large or small bobbin with a single winder having a normal configuration. That is, the interval and the stroke of the pintle are set to correspond to the large bobbin, and when the small bobbin is mounted, the collar is interposed between the pintle and the bobbin. In addition, the lifter stroke is set to correspond to a large bobbin, and when mounting a small bobbin, a step is interposed between the lifter and the bobbin.

In the above-described means, when winding onto a small bobbin, a collar, a step, etc., must be installed when the bobbin is attached and detached. Must be separated by rolling. The above-mentioned collars, steps, full bobbins and the like are all heavy objects, and handling of them involves considerable danger.

The present invention has been made based on the above circumstances, and the drive source of the winder can be used in common to accommodate large and small bobbins, and can be provided at a low cost with a relatively simple configuration, and can handle dangerous heavy objects. Provide a winding machine that does not require any work.
