Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to a device for winding a magnetic tape in a cassette case having a guard panel, and more particularly to a device for pulling out a leader tape from the cassette case, connecting the magnetic tape in the middle of the leader tape, and winding the leader tape in a hub.

[Prior art]

There are roughly two types of manufacturing methods for magnetic recording tape cassettes. The first method is to wind magnetic tape around a pair of hubs outside the cassette case, and then to fill it in the cassette. This method is a large-scale device with a complicated mechanism of the entire device. The tape wrapping time is short and the processing capacity per short time is high, making it suitable for large-scale plants. The second method is to store the hub connected with the leader tape in the case in advance, pull out the leader tape from the cassette case, connect the magnetic tape to this, and rotate the hub in the cassette case to wind the magnetic tape. This method has a feature that the whole device can be simplified and the magnetic tape can be wound in a small device. The apparatus of the second method is shown in Japanese Patent Publication No. 52-45203. As shown in FIG. 9, this device pulls out a leader tape 2 from a cassette case 1,
To the tape supports 3 and 4 of
The second tape support 3 is cut between the second tape supports 3 and 4,
The third tape support 5 that moves together with the magnetic tape 6 and attracts the magnetic tape is brought close to the first tape support 3, and the magnetic tape 6 is connected to the end of the leader tape 2, and then,
When the first and third tape supports are released from the attracted state, the hub in the cassette case 1 is rotated to wind the magnetic tape 6, and when the magnetic tape 6 having a predetermined length is wound, the magnetic tape 6 is rewound. After adsorbing with the first and third tape supports 3 and 5 and cutting the magnetic tape between both tape supports 3 and 5, the second and third tape supports 4 and 5 are moved, Second
The tape support 4 of 1 is brought close to the first tape support 3,
The cut end of the leader tape 2 is connected to the end of the magnetic tape 6, and the tape pull-out portion is wound into the cassette case. Another method of supplying the front end of the magnetic tape to the end of the cut leader tape has also been developed (Japanese Patent Publication No. 4).
9-30444). This device also pulls out the leader tape from the cassette case, cuts the middle of the leader tape, connects the magnetic tape here, winds the magnetic tape in the cassette case, cuts the magnetic tape, and then ends the end with the leader tape. Connected.

[Problems to be Solved by the Invention]

These conventional methods have a structure in which the leader tape is pulled out from the cassette case so that it is convenient to cut the leader tape in the middle and connect the magnetic tape to it. In the process of taking, the magnetic tape runs on the tape guide in the cassette case. That is, the magnetic tape wound around the cassette case runs along the expansion guide of the winding device outside the cassette case, but inside the cassette case, the magnetic tape stays inside the cassette case as in the normal recording and reproducing state. Run along the tape guide. Since the expansion guide of the winding device can be made highly precise and precise finish, it can be run at high speed without damaging the magnetic tape, but the tape guide in the cassette case is highly accurate because of its cost. I can't do a precise finish. Therefore, in the high-speed winding process of the magnetic tape, when the tape guide in the cassette case is used, the magnetic tape is apt to be scratched, and the magnetic tape cannot be accurately aligned and wound at high speed. Magnetic tapes that are not neatly aligned and wound up cause a step on the peripheral edge of the magnetic tape, and this stepped portion hits the inner surface of the cassette case during transportation of the cassette case, and the impact causes the peripheral edge of the magnetic tape to break or be damaged. There was a defect that caused. In order to solve this drawback, the present invention changes the pull-out state of the leader tape pulled out from the cassette case, so that the magnetic tape can be wound in the cassette case at high speed with little scratches, and moreover, the magnetic tape can be wound. (EN) It is possible to provide a magnetic tape cassette case winding device that can be neatly aligned and wound, and can shorten the winding time and improve the processing capacity. Another important object of the present invention is to shorten the amount of leader tape pulled out from the cassette case, and to shorten the time required for pulling out the leader tape and the final pulling-in of the slack portion. It is an object of the present invention to provide a device for winding a magnetic tape inside a cassette case, which can remarkably improve the processing capacity per unit time in cooperation with the reduction in time.

The carriage 30 adsorbs the splicing tape 28 on its lower surface and advances from right to left to deliver the splicing tape 28 of a certain length to the intermediate suction table 31 and the pressing member 29. When the carriage 30 moves from left to right, it does not adsorb the splicing tape 28. In this state, the tip of the splicing tape 28 is sucked by the intermediate suction table 31. The cutter 32 rises with the pressing member 29 and the intermediate suction table 31 adsorbing the splicing tape 28, and cuts the splicing tape 28 at the rear end surface of the pressing member 29. In the step of connecting the leader tape 2 and the magnetic tape 6 with this connecting member, the cutter 19 for cutting the leader tape 2 or the magnetic tape 6 stands by outside the passage of the pressing member. The operation of the magnetic tape in-cassette winding device configured as described above to wind the magnetic tape into the cassette case is as follows. The cassette case 1 is held in place by the support means and the guard panel is opened. The expansion guide 10 located inside the leader tape 2 moves to pull out the leader tape 2 from the cassette case 1 and suck it onto the upper surfaces of the first and second holding members 11 and 12. In this state, the first and second holding members 11 and 12 are adjacent to each other with their upper surfaces flush with each other, and the third holding member 13
Waits at the position indicated by the solid line in FIG. The cutter 19 penetrates between the first and second holding members 11 and 12 to cut the leader tape 2. In this state, the first and second holding members 11 and 12 are the leader tape 2
Is held in the adsorbed state. The second holding member 12 moves away from the first holding member 11 to the standby position, and the third holding member 13 moves to a position adjacent to the first holding member 11 to make the upper surface flush with each other. . Even in this state, the first, second and third holding members 1
1, 12, 13 adsorb the leader tape 2 and the magnetic tape 6. The leader tape 2 and the magnetic tape 6 which are attracted by the first and third holding members 11 and 13 and are adjacent to each other on the same plane are connected by a connecting means. After that, the first and third holding members 11 and 13 release the attracted state, and the hub 24 to which the leader tape 2 connected to the magnetic tape is fixed is rotated by the rotating means to place the magnetic tape 6 in the cassette case 1. Get involved. At this time, the magnetic tape 6 is guided into the cassette case by the expansion guide 10, and the tape guide 35 of the cassette case is not used as a guide for winding the magnetic tape. After the magnetic tape 6 having a predetermined length is wound, the hub 24
Is stopped, and the magnetic tape 6 is adsorbed by the first and third holding members 11 and 13. The cutter 19 enters and cuts the magnetic tape 6 between the first and third holding members 11 and 13. The third holding member 13 adsorbs the magnetic tape 6 and moves to the standby position shown by the solid line in FIG. 1, and the second holding member 12 moves from the standby position shown by the solid line in FIG. It moves to the position adjacent to the first holding member 11 shown by the chain line in FIG. The connecting means connects the end of the magnetic tape 6 attracted by the first holding member 11 and the cut end of the leader tape 2 attracted by the second holding member 12. In the process, the first, second and third holding members 1

The hub 24 is rotated and the looseness of the tape is drawn into the cassette case 1. Replace the cassette case 1 with another one that is not wrapped with magnetic tape. The magnetic tape is wound around the cassette case by repeating this process. In the apparatus of the present invention shown in FIG. 4, the cassette case is vertically positioned with the opening portion facing downward, and the leader tape pulled out from the cassette case is surrounded by the cassette case, the guard panel and the holding member, and the leader tape is formed. It is possible to prevent dust from adhering to the. In FIG. 4, it is also possible to turn the whole apparatus upside down, that is, to make the opening of the cassette case face up and enclose the upper surface of the leader tape pulled out to the opening of the cassette case so as to cover it with a holding member. . Regardless of the holding direction of the cassette case, as long as the relative position of the cassette case and the holding member is specified, the leader tape pulled out from the cassette case is surrounded by the cassette case, the holding member, and the guard panel, Are prevented from adhering. Therefore, the present invention does not limit the attitude of holding the cassette case. In the cassette case shown in FIG. 6, the bottom plate has a double structure, the outer bottom plate is slidably attached to the case body, and the outer bottom plate is slid in a state where the cassette case is taken out from the apparatus to slide the cassette case into the cassette case.

The cassette case having this structure can minimize the dust attached to the magnetic tape after the magnetic tape is wound.

【The invention's effect】

In the apparatus for winding a magnetic tape in a cassette of the present invention, the expansion guide for pulling out the leader tape from the cassette case is also used as the guide for the tape for winding the magnetic tape in the cassette case. Therefore, as compared with the conventional method of winding the magnetic tape in the cassette case using the tape guide in the cassette case, the magnetic tape can be neatly aligned with less scratches and can be wound at high speed. It is because the in-cassette wrapping device of the present invention uses a spreading guide having a surface finish that is higher in processing accuracy than the tape guide of the cassette case and has a precise surface finish, and the magnetic tape is cassette with excellent running stability. This is because it can guide you to the hub of the case. The tape guide built into the cassette case also guides the magnetic tape to the hub. However, the tape guide is for guiding the magnetic tape when the cassette case is set in the electric device. The running speed of the magnetic tape in the actual use state is so slow that it cannot be compared with the winding speed of the magnetic tape in the manufacturing process. In the manufacturing process, it is required to wind the magnetic tape around the hub at an extremely high speed in order to shorten the takt time. The tape guide is designed to guide the magnetic tape during use. It is not designed to guide high speed magnetic tape to the hub. This is because the manufacturing cost is reduced and it is not necessary. Therefore, when the magnetic tape is wound around the hub at high speed using the tape guide, the magnetic tape cannot be neatly aligned and wound. The tape winding device of the present invention does not use the tape guide as a winding guide for the magnetic tape. The magnetic tape wound at high speed in the cassette case is guided to the hub by the expansion guide. The expansion guide is not installed in the cassette case, but is installed in the manufacturing apparatus. Therefore, it can be processed with extremely high accuracy. The expansion guide that can be processed with high precision can wind the magnetic tape at high speed for two reasons, neatly align and wind the magnetic tape, and prevent scratches on the magnetic tape. The first reason is that the magnetic tape can be guided to an accurate position without play. Tape guides with low processing accuracy
It may not be possible to neatly align and wind the magnetic tape because it is vibrated by the magnetic tape running at high speed. Further, the accuracy of the tape guide itself is low, and the running position of the magnetic tape may be misaligned and may not be aligned. The apparatus of the present invention can eliminate this drawback by the high-precision expanding guide. The second reason that the magnetic tape can be prevented from being damaged is that the magnetic tape running surface of the expansion guide can be processed with high accuracy to prevent the magnetic tape from being damaged. Further, in the cassette winding device of the present invention, the expansion guide for pulling out the leader tape from the cassette case is also used as the tape guide. Therefore, there is a feature that the structure of the entire device can be simplified. Further, in the device of the present invention, since the expansion guide for pulling out the leader tape is also used as the tape guide, the amount of leader tape to be pulled out can be made extremely small, the overall length of the leader tape can be shortened, and the non-recording areas at both ends of the tape can be shortened. It is also possible to realize the feature that can reduce the Furthermore, the leader tape can be pulled out from the cassette case, the movement of the member for guiding the leader tape and the magnetic tape can be reduced, and the pull-out amount of the leader tape can be shortened. It is possible to shorten the moving time of the member, that is, the leader tape drawing time and the final winding time of the slack portion, and it is possible to increase the processing capacity per unit time.
