Abstract

PURPOSE:To effectively prevent disturbance and meandering by urging a press- roller so that a plurality of a tapes are nipped in succession by a metal roller and a rotary driving roller. CONSTITUTION:A press roller 32 is urged by an elastic member 32b so that the tapes T... cut by a plurality of round cutting edges 23a of a cutting tool 23 are nipped by a metal roller 21 and a rotary driving roller 31, and the disturbance and meandering are prevented by eliminating the in-air traveling of the tape T. A tape taking-up rod 42 rolls, urged onto a rotary driving roller 31 by an elastic member 41a, and the tape T... is taken-up always in contact state, and therefore, the taking-up in arranged state free from disturbance is permitted. Therefore, even if the transport speed of a cut article and a tape is high, the superior meandering preventing performance can be obtained by the simple and low-cost structure.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a tape cutting device for cutting a long sheet-like object into tapes, and particularly to a tape cutting device that cuts a long sheet-like object into tapes, and in particular, it is capable of cutting cut tapes smoothly without disturbing them. The present invention relates to a tape transport/winding mechanism in a tape cutting device that transports and winds a tape.

<Prior Art> Conventionally, the feeding/winding mechanism of this type of tape cutting device has been to feed and drive a long sheet material to be cut using a combination of a press roller and a rotary drive roller. The conveyance state is detected by a photoelectric g sensor disposed at the edge of the cut object being conveyed, and a cross guider widely used in sewing machines provides appropriate conveyance resistance to prevent meandering.

Further, each cut tape was wound onto a reel prepared for each tape.

<Problems to be Solved by the Invention> However, in such a conventional transport/winding mechanism, the structure of the tape cutting device is complicated.

In addition to increasing costs, this method has the disadvantage that it cannot effectively prevent meandering of a tape cut into multiple pieces.

Means for Solving the Problems> The present invention is intended to solve the above problems,
The circumference will be explained below using the gz diagram and FIG. 4 corresponding to the example.

The cutting means 2 is rotated by the rotation drive means 33 in the feeding direction of the object to be cut, and the cutting means 2 is rotated at the contact portion with the object to be cut.
A metal roller 21 serves as a support for cutting the long sheet-like object A into a plurality of tapes T in cooperation with the cutting tool 23 of No. 0, and a plurality of tapes cut by the metal roller 21. A press roller 32 is urged by an elastic member 32b to roll so as to sandwich the tape T-, and the press roller 32 and the plurality of cut tapes T are sandwiched between the press roller 32 and the plurality of cut tapes T. A rotary drive roller 31 that is rotatably driven and transferred in the same direction as the feeding direction, and an elastic member 41m that sandwiches a plurality of tapes T-. between the rotary drive roller 31.
The tape transport/winding mechanism in the tape cutting apparatus of the present invention is constituted by the winding rod 42 which is biased by the winding rod 42 and rolls to wind up the plurality of tapes T-.

Therefore, the present invention has a very simple structure and low cost due to the above configuration, and has excellent meandering prevention performance even when the conveyance speed of the cut object and tape is high, and in particular, tapes cut into multiple rows can be cut without disturbance. The purpose of the present invention is to provide a mechanism for transporting and winding up four tapes in a tape cutting device that transports and winds them in an aligned state.

As can be easily understood from FIG. 4, the tape T- is always pushed by the rollers 21, 32, . Since it is in contact with ll, there is no part where it travels in the air, and it is turbulent.

Meandering is effectively prevented. Furthermore, the winding rod 42.

The rotational drive is further biased by the elastic member 41a and rolls together with the tape T- wound around the circumference, and the tape T- is wound up in a constant state of contact, so that it is aligned without disturbance. Winding is possible.
