Description

Description: TECHNICAL FIELD The present invention relates to a method of winding a tape around a hub previously filled in a cassette case, and more particularly to a case where a cassette case is provided at a supply position, a winding position, and a discharge position. The present invention relates to a tape winding method for a cassette case that is turned upside down and held.

[Prior Art] There are roughly two methods for winding a magnetic recording tape in a cassette case. The first method is to wind the magnetic tape around the pair of hubs outside the cassette case and then fill the magnetic tape in the cassette case. In this method, the mechanism of the entire device is complicated and the device is large-scale, but the winding time of the magnetic tape is short, the processing capacity per hour is high,
Suitable for large-scale manufacturing plants.

The second method is to wind the tape in a state where the hub is housed in the cassette case, that is, the hub around which the short leader tape is wound is housed in the cassette case, and then the leader tape is pulled out and the magnetic tape is put on the leader tape. It is a method of connecting and rotating the hub in the cassette case to wind the magnetic tape. This method has the advantage that the entire device can be simplified and the magnetic tape can be wound in a small device.

The present invention relates to an improvement of the second method.

[Problems with the prior art] What is important in the process of pulling out the leader tape from the cassette case, connecting the magnetic tapes and winding them around the hub is that the leader tape is pulled out and pulled in securely.
Moreover, it is to prevent damage to the leader tape as much as possible. Reliable pulling out and pulling in of the leader tape reduce abnormal stop time due to malfunction during work in the automatic machine to improve productivity and prevent leader tape damage.
Effective in improving product quality. To achieve this, the inventor of the present invention stands the cassette case filled with the hub with the tape pull-out surface facing downward to reduce the pull-out amount of the leader tape so that the magnetic tape is placed under the cassette case. We have developed a method for connecting and disconnecting. In this method, the upper portion of the processed portion of the leader tape is covered with the cassette case, and since the amount of pulling out is short, abnormal operation is reduced and a high quality cassette case can be manufactured.

The present inventor has further improved this system and developed a system for automatically feeding an empty cassette case and taking out a wound cassette case.

However, when supplying and discharging the cassette case with the tape pull-out surface facing down, the cassette case itself and the tape are easily damaged at the supply and discharge positions, and compared with the method of manually supplying and removing the cassette case by hand. However, there is a drawback that the incidence of defective products increases.

The present invention was developed to solve this drawback, and an important object of the present invention is to reduce the damage to the tape and the cassette, and to manufacture a cassette case for high quality magnetic tape. To provide a winding method.

[Means for Solving Conventional Problems] A tape winding method for a cassette case is as follows. An empty cassette case is sent from a supply position to a winding position, the tape is wound around an internal hub at the winding position, and the tape is wound. The rolled cassette case is sent to the discharge position. At the supply position, the empty cassette case faces the tape pull-out surface, and the empty cassette case is turned upside down to carry the cassette case to the winding position with the tape pull-out surface facing downward. The cassette case supplied with the tape pull-out surface facing down is wound around the reel at the winding position. After winding the tape, the wound cassette case is turned upside down again, and the tape is pulled out to the discharge position with the tape pull-out surface facing up.

[Effect] At the supply position and the discharge position, the cassette case has the tape pull-out surface facing upward. Therefore, the tape pull-out surface does not hit the holder of the cassette case, and the sturdy back of the cassette case hits the holder. Therefore, at this position, damage to the tape pull-out surface can be minimized. In particular, a cassette case for a video tape or the like has a fragile opening / closing lid on the tape running surface, and the method of the present invention in which this is arranged upward can minimize damage to the opening / closing lid. In addition, supply,
At the discharge position, the easiest way to transfer the cassette case is to drop it along the guide, but when the cassette case is dropped and stopped at a fixed position, the lower surface collides with the support base. According to the present invention, since the lower end is the back surface of a sturdy cassette case, damage to the cassette case and the tape can be prevented even if the cassette case is dropped and transferred, and a high quality cassette case can be manufactured with a simple supply / discharge mechanism. it can.

Further, in the step of winding the tape around the cassette case, the tape pull-out surface is arranged downward, so that the tape pulled out from the cassette case can be connected and cut while being covered with the cassette case. In particular, the leader tape that is pulled out short from the downward cassette case can press the adhesive tape on the upper surface of the drawn portion, so the tape connecting portion is guided to the fixed position of the guide by its own weight, and it is possible to ensure high accuracy without displacement. The feature that can be connected to

Further, the cassette case which is turned upside down at the feeding / discharging position and the winding position is transferred, since the cassette case can be gripped at the end of the rotating arm and the rotating arm can be rotated by 180 degrees and transferred. A feature that can be accurately transferred to a fixed position is also realized.
