Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for winding a thick tape represented by a bobbin winding tape such as a carrier tape for semiconductor parts and a tear tape for opening a cardboard box.

[0002]

2. Description of the Related Art A bobbin winding tape of this type is described in, for example, Japanese Utility Model Laid-Open No. 3-1944, and as a winding device thereof, for example, as shown in FIG. It is generally known that A, a comb-shaped blade B, and a plurality of bobbins C _{1 to} C ₆ (six in the configuration example of the drawing) that are cores are used.

In this case, the bobbins C _{1 to} C ₆ are divided into upper and lower groups, and the bobbins of each group are arranged at a predetermined interval in the tape length direction, that is, on the downstream side of the blade B.
Therefore, the blade B has a different separation distance for each bobbin C ₁ , C ₂ , C ₃ (or C ₄ , C ₅ , C ₆ ),
As the number of bobbins arranged increases, the difference between at least the maximum and minimum separation distances increases.

[0004]

However, in the structure of the above-mentioned conventional device, in order to make it easy to find the tape winding end of each bobbin on which the tape is wound, for example, a so-called lead portion is formed at the tape winding end. In the case of providing, it was necessary to go through the following troublesome process.

That is, a colored film piece which is a take-up portion is attached to each bobbin for which the winding process has been completed, or
Looking at the time of the end of winding, the colored film piece is once attached to the raw tape at the position immediately before the blade B, and when the take-up portion is wound, the winding is finished The thin tape wound around the roll is unwound, the excess tape portion is removed, and then the colored film is attached again.

[0006] Further, when such a mouthpiece is attached,
As described above, not only is the work troublesome, but there are also problems in that the attachment position of the take-up portion differs from bobbin to bobbin, and the winding length of the winding tape on the bobbin cannot be made constant.

When increasing the number of bobbins to be arranged, there is a method of increasing the number of bobbins along the tape length direction as well as a method of increasing the number of bobbins in the tape width direction. , The installation space (particularly the portion on the downstream side of the cutting tool B) expands so as to widen the angle of the fan shape, so that the installation space becomes larger than the former method.

The present invention has been made to solve the above-mentioned problems of the prior art. The winding lengths for a plurality of cores are made the same, and the number of cores provided is increased to some extent. Another object of the present invention is to provide a thick-tape winding device that does not unnecessarily expand the installation space.

[0009]
