Abstract

PURPOSE:To decrease the injuries of a tape and a cassette and to improve their qualities by forming a cassette case so that the tape lead-out plane of the case is turned upward at both feed and ejection positions. CONSTITUTION:A cassette case 4 is erected at a feed position 1, a winding position 2 and an ejection position 3 respectively. A tape lead-out plane 5 of the case 4 is turned upward at positions 1 and 3 and then turned downward at the position 2. Therefore, the case 4 turned upside down when it is shifted between positions 1 and 2 and then between positions 2 and 3 respectively. Thus the case 4 is held between both ends of a rotary arm 6 which turns by 180 deg. within a vertical plane and shifted. It is possible to decrease the injuries of both a tape and a cassette and also to improve the qualities since the plane 5 of the case 4 is turned upward positions 1 and 3.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a method of wrapping a tape around a hub filled in a cassette case in advance, and in particular, the present invention relates to a method of wrapping a tape around a hub filled in a cassette case in advance. This invention relates to a tape winding method for a cassette case that is held upside down.

[Prior Art] The methods of winding magnetic recording tape inside a cassette case can be roughly divided into 2V! be. The first method is to wrap a magnetic tape around a pair of hubs outside the cassette case, and then fill it into the cassette case. This method is
Although the entire loading mechanism is complex and the device is large-scale, winding magnetic tape takes a short time and has a high throughput per hour, making it suitable for large-scale manufacturing plants.

The second method is to wind the tape with the hub stored in the cassette case. In other words, after storing the hub with a short leader tape wrapped around it in the cassette case, pull out the leader tape and wrap the magnetic tape around it. Connect the hub and rotate the hub inside the cassette case to wind up the 8i tape. This method makes the entire device easy and compact! It has the advantage of being able to wind up magnetic tape.

The present invention is an improvement on the second method.

[Conventional problems] In the process of pulling out the leader tape from the cassette case, connecting the magnetic tapes, and wrapping them around the hub, it is important to ensure that the leader tape can be pulled out and pulled in reliably.
Moreover, the purpose is to prevent damage to the leader tape as much as possible. Reliable pull-out and retraction of leader tapes improves productivity by reducing abnormal stoppage times due to malfunctions during work in automatic machines, and preventing damage to leader tapes is effective in improving product quality. In order to achieve this, the inventor of the present invention stands a cassette case filled with hubs with the tape extraction surface facing downward, reduces the amount of leader tape pulled out, and places the magnetic tape under the cassette case. We have developed a method for connecting and disconnecting. In this method, the upper part of the leader tape to be processed is covered by the cassette case, and since the amount of extraction is short, malfunctions can be reduced and high-quality cassette cases can be manufactured.

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

However, if the cassette case is fed and ejected with the tape drawer side facing downward, the cassette case itself and the tape are more likely to be damaged at the feeding and ejection positions, compared to a method in which the cassette case is directly fed and ejected manually. However, there was a drawback that the incidence of defective products increased.

The present invention has been developed to further solve this drawback, and an important object of the present invention is to minimize damage to tapes and cassettes, and to manufacture high-quality magnetic tape cassette cases. To provide a winding method.

[Means for solving conventional problems] The method for winding a cassette case with tape is to send an empty cassette case from the supply position to the winding position, wrap the tape around the internal hub at the winding position, and then wrap the tape around the internal hub. The wound cassette case is sent to the ejection position.

Supply position! Now, turn the empty cassette case with the tape pull-out side facing upward, turn the empty cassette case upside down, and carry the cassette case to the winding position with the tape pull-out side facing downward. The cassette case is supplied with the tape drawer side down, and the tape is wound around the reel at the winding position. After winding the tape, the wound cassette case is turned upside down again and sent to the ejection position with the tape extraction surface facing up.

[Function and Effect] At the supply position and the discharge position, the cassette case has its tape extraction surface facing upward. Therefore, the tape pull-out surface does not come into contact with the holding stand of the cassette case, and the sturdy back of the cassette case does not come into contact with the holding stand. Therefore, at this position, damage to the tape drawing surface can be minimized. In particular, cassette cases for audiotapes and the like have fragile lids on the tape running surface, but the method of the present invention in which the lids are disposed upward can minimize damage to the lids. Furthermore, supply,
The easiest way to transport the cassette case at the ejection position is to drop it along a guide, but when the cassette case is dropped and stopped at a fixed position, the bottom surface collides with the support stand. In the present invention, since the lower end is the back of the cassette case, the cassette case and tape can be prevented from being damaged even if the cassette case is dropped and transported, and a high-quality cassette case can be manufactured with a simple feeding and ejecting mechanism. can.

Furthermore, in the step of winding the tape into the cassette case, since the tape drawing surface is disposed downward, the tape drawn out from the cassette case can be connected and cut while being covered by the cassette case. In particular, when the leader tape is pulled out for a short length from the downward facing cassette case, the adhesive tape can be pressed against the top surface of the pulled-out part, so the tape connecting part is guided to the correct position on the guide by its own weight, ensuring high precision without misalignment. It is possible to realize features that can be connected to

Furthermore, the cassette case, which is transferred upside down at the supply/discharge position and the winding position, can be transferred by gripping the cassette case at the end of the rotating arm and rotating the rotating arm 180 degrees, making it possible to transfer the case with a simple transfer member. The feature of being able to be transported accurately to a fixed position is also realized.

The tape draw-out surface 5 of the cassette case 4 at the supply position 1 and discharge position 3 faces upward, and the tape draw-out surface 5 of the cassette case 4 at the winding position 20 faces downward. Therefore, the supply position l
When the cassette case 4 is transferred from the winding position 2 to the winding position 2, the cassette case 4 is turned upside down, and when it is transferred from the winding position 2 to the discharge position 3, the cassette case 4 is also turned upside down.

The easiest way to transfer a cassette case is to invert it during transfer, and to ensure that it can be transferred quickly,
