Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel tape in which products such as terminals and lead frames are molded by a press, and the chain-shaped product tape after the press processing is polymerized with a paper tape usually called an interlayer paper. The present invention relates to a winder that winds a take-up reel.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication No. 61-123416 discloses a winding machine invented by the present applicant. In this conventional winding machine, a take-up reel drive source and a paper tape reel support shaft are juxtaposed on the take-up side and the standby side of a turntable provided on the machine base, respectively, and the front side of the standby-side take-up reel drive source is provided. By the take-up reel exchange robot moving along, the finished product reel is taken out from the take-up reel support shaft and conveyed to the finished product storage section, and after mounting the take-up reel from the spare reel storage section on the take-up support shaft, The beginning end of the paper tape was attached to the reel shaft of the take-up reel.

[0003]

In the above-mentioned winding machine, the exchange of the finished product reel and the take-up reel and the work of attaching the starting end of the paper tape are performed by the exchange robot (the exchange of the paper tape reel is performed manually). If the work of attaching the starting end of the paper tape is performed by the exchange robot, the starting end of the upward facing paper tape nipped by the tension device may be tilted by its own weight or may be curved and may not be properly gripped by the starting end gripping device. Further, even if the starting end of the paper tape is correctly grasped, the starting end of the paper tape is merely pressed against the reel shaft of the take-up reel, which causes a sticking error. Also, care must be taken in selecting the adhesive, and the paper tape will peel off if the drying time is too long or too short.

Further, if the exhaustion of the paper tape on the paper tape reel is neglected and the paper tape runs out during operation on the winding side,
It is necessary to stop the operation of the winder, manually load the paper tape onto the paper tape reel, and join the starting ends of the paper tape.

Therefore, even if the take-up reel is automatically replaced by the folding-angle changing robot, the worker must check the consumption state of the paper tape on the paper tape reel and the sticking state of the paper tape starting end every time the worker changes. Was unable to leave the winder for a long time. Although repeated studies have been carried out to solve these problems, it is difficult to completely automate the paper tape in consideration of economy because the paper tape is not a rigid body. Therefore, according to the present invention, a take-up reel and a paper tape reel, which are conventionally provided in a take-up machine, are housed in a reel cassette, and the reel cassette is automatically replaced.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a reel in which a take-up reel and a paper tape reel having a paper tape wound around a cassette body are rotatably supported, and a starting end of the paper tape is attached to a reel shaft of the take-up reel. The cassette, the reel rotation device that rotates the take-up reel of the reel cassette stopped at the winding position, and the reel cassette before winding by intermittently moving a plurality of reel cassettes at a predetermined interval at the same time. The present invention is composed of a reel cassette moving device for sending out the reel cassette which has been wound up and wound up, and the product tape is wound around the winding reel of the reel cassette.

[0007]

The reel cassette containing the take-up reel and the paper tape reel in which the starting ends of the paper tapes are attached to the reel shaft is wound by the reel cassette moving device every time the take-up reel is completely wound and becomes a finished product reel. At the same time as the reel cassette is sent to the take-up position, the reel cassette that has been wound up is automatically sent out from the take-up position to the cassette exchange position side. Therefore, the reel cassette is set to the winding position in a short time such that the reel cassette moves for a predetermined distance, and the next winding operation is started.
