Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically winding a web around a core tube such as a paper tube.

[0002]

2. Description of the Related Art As one of methods for winding a web around a core tube such as a paper tube, the core tube is placed on a pair of driving drums, and the starting end of the web is fixed to the core tube, and then the above-mentioned driving is performed. There is a method in which the drum is rotated in the same direction to wind the core tube while rotating it. After the winding is completed, the web is cut, the winding body is removed from the driving drum, the next core tube is guided to the driving drum, and the same operation is repeated.

In this case, the operation of winding the web around the core tube on the pair of drive drums can be automatically and smoothly performed, but the starting end of the web must be fixed to the core tube before winding. I have to. The typical fixing means conventionally used are as follows.

One of them is the adhesive tape attaching method shown in FIG. That is, the starting end of the web (w) is attached to the core tube (s) by a manual or semi-manual method using an adhesive tape (T).

The other one is a method of using a core tube with a tongue-like cut shown in FIG. That is, a slit-shaped tongue-shaped cut (C) is provided in the core tube (s), and this cut (C)
Insert the starting end of the web (w) manually into the and then start winding. The cut (C) is exaggerated in FIG.

[0006]

However, both the above-mentioned adhesive tape sticking method and the method of using the core tube with the tongue-like notch fix the starting end of the web to the core tube by hand or semi-manually. Therefore, the operation is interrupted each time a new core tube is wound, which is disadvantageous in terms of productivity.

[0007] In addition, in these methods, it is easy to cause individual differences in sticking or inserting work, and when the sticking or inserting state is poor, the winding shape of the web is bad and the work must be redone. There was something I had to do.

Under such circumstances, the present invention aims to provide an automatic web winding device capable of automatically performing all the steps including the step of fixing the starting end of the web to the core tube. It is what
