Description

Description: TECHNICAL FIELD The present invention relates to a device for winding a magnetic tape in a cassette case having a guard panel and a slider, and in particular, pulling out a leader tape from the cassette case and in the middle of the leader tape. To a device for connecting a magnetic tape to and winding the magnetic tape around a hub.

[Prior Art] In recent years, magnetic tapes have a high recording density, and the influence of surface deposits tends to increase. A foreign substance attached to the surface causes a bit error, which causes noise in PCM recording, causes a recording error in a magnetic recording tape such as a computer, and causes noise in a video tape. Cause image quality deterioration.

By the way, 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 to which the leader tape is connected in advance in the case, pull out the leader tape from the cassette case, connect the magnetic tape to this, and rotate the hub in the cassette case to remove the magnetic tape. With this method, the entire apparatus can be simplified by the winding method, and since the magnetic tape is immediately wound into the cassette case, the amount of foreign matter such as dust adhering to the surface of the magnetic tape can be reduced.

The present invention relates to an improvement of the apparatus used in the second method, and in particular, it is an apparatus developed for the purpose of reducing the amount of dust adhered to the surface of the magnetic tape.

By the way, the smaller the amount of foreign matter such as dust adhering to the tape surface, the higher the quality of magnetic recording and reproduction becomes possible.

Particularly, the leader tape pulled out from the cassette tape is a synthetic resin film such as polyester, which has a high insulating property and is easily charged with electricity, and dust or the like is easily attached by static electricity. Since magnetic powder such as iron oxide or pure iron is attached to the surface of the magnetic tape, the magnetic tape has higher conductivity than the leader tape, and dust and the like are less likely to adhere to the leader tape. Foreign matter such as dust adhering to the surface of the leader tape does not adversely affect recording and reproduction unless the foreign matter is transferred from the leader tape to the magnetic tape. However, the foreign matter adhering to the leader tape adheres to the surface of the guide roller or the like in the cassette case and is transferred to the surface of the magnetic tape. Therefore, it is important for high density magnetic recording to minimize foreign matters such as dust adhering to the surface of the leader tape.

The tape wound in the cassette case prevents dust from adhering to the cassette case. On the tape, foreign matter such as dust is likely to adhere to the tape pull-out portion in the cassette case. Therefore, in order to reduce the amount of dust adhered, a cassette case was developed to prevent dust from adhering when the cassette tape is not used by providing a guard panel with an L-shaped cross section at the tape drawer portion of the cassette case. ing.

The L-shaped guard panel alone cannot completely cover the tape in the tape drawing portion of the cassette case, and foreign matter enters the cassette case through the hub hole for rotating the hub that is opened in the cassette case. Therefore, as shown in FIG. 1, a cassette case has been developed in which a slider is slidably provided on the back surface of the cassette case.

A conventional magnetic tape winding device opens a slider to wind the magnetic tape around the hub, winds the magnetic tape around the hub in this state, winds the magnetic tape of a predetermined length around the hub, and then removes only the guard panel. It is closed and discharged.
At this time, a rotation drive shaft is inserted in the hub for winding the magnetic tape. Therefore, in this state, the slider cannot be closed, only the guard panel is closed, and the cassette case wound with the magnetic tape is ejected to the outside of the apparatus with the slider open. The magnetic tape wound on the hub is wound on one hub.
That is, the magnetic tape is wound around one hub in a rewound state so that the cassette case can be used immediately. In this state, in the tape drawer part of the cassette case,
A leader tape is exposed to which dust is likely to adhere. Therefore, the cassette case taken out of the winding device in this state has a drawback that foreign matter is likely to adhere to the leader tape.

[Object of the invention] The present invention was developed to solve this drawback, and an important object of the present invention is to remove the cassette case by closing both the guard panel and the slider.
An object of the present invention is to provide a magnetic tape cassette case wrapping device capable of minimizing the amount of foreign matter attached to the leader tape and reducing the occurrence rate of bit errors.

[Means for Solving the Problems of the Related Art] The apparatus for winding a magnetic tape in a cassette case according to the present invention includes a cassette case supporting means having a tape guard panel for covering the tape pull-out portion, and a hub in the cassette case. Holding means for pulling out and holding the leader tape having both ends connected to the outside of the case, cutting means for cutting the leader tape held by the holding means, and a magnetic tape at the cut end of the leader tape cut by the cutting means. A connecting means for connecting the tips, a rotating means for rotating the leader tape connected hub to which the magnetic tape is connected to wind the magnetic tape around the hub, and a temporary fixing member for holding the cassette case around which the tape is wound, A stopper release member that presses the slider lock of the slider of the cassette case held by this temporary fixing member, and this stopper release A slider closing member that contacts the lid and moves the slider to the guard panel side when the slider lock is pressed by the member is provided.

[Operation and Effect] The magnetic tape in-cassette winding device of the present invention holds the supplied cassette case by the supporting means, and in this state, the guard panel and the slider are opened to pull out the leader tape and the cutting means. The cutting end is held by the holding means. The hub is connected to the cut end by the connecting means, and the hub to which the leader tape connected to the magnetic tape is connected is rotationally driven by the rotating means to wind the magnetic tape of a predetermined length around one hub. After that, the rear end of the magnetic tape is cut and connected to the leader tape, and the magnetic tape is wound in the cassette case. The cassette case in which the winding of the magnetic tape is completed is held by the temporary fixing means. In this state, the slider lock of the slider is pushed by the stopper release member, and the locked state of the slider is released. In this state, the slider closing member moves the lid to the guard panel side to close the slider.

As described above, the winding device of the present invention in which the cassette case is held by the temporary fixing member and the slider is closed from the winding position of the magnetic tape is the guard panel after the predetermined length of the magnetic tape is wound around the hub. Both the slider and the slider are closed. In this state, the tape drawer of the cassette case is completely closed by both the guard panel and the slider.
Further, the hub hole for rotating the hub is also closed. Therefore, it is possible to prevent the leader tape at the tape pull-out portion of the cassette case from being completely covered by the guard panel and the slider, and preventing foreign matter from adhering to this. It is also possible to prevent foreign matter from entering the cassette case through the hub hole of the cassette case. Therefore, it is possible to minimize the bit error of the magnetic tape that occurs when foreign matter adheres to the leader tape, and it can be used in a PCM recorder to reduce noise and record and reproduce high-quality sound. The rate of error occurrence can be reduced, and in the case of video tapes, the features of recording and playback with beautiful image quality can be realized.

However, the examples shown below exemplify a device for wrapping a magnetic tape in a cassette case for embodying the technical idea of the present invention. The structure and arrangement are not specified in the structure below. This invention, within the scope of the claims,
Various changes are made.

In the apparatus for winding a magnetic tape in a cassette case according to the present invention, as shown in FIG. 1, a magnetic tape 4 is wound around a cassette case 3 having a guard panel 1 and a slider 2. First
A cassette case 3 shown in the figure includes a guard panel 1 having an L-shaped cross section and a slidable slider.

The guard panel is a shaft (not shown) provided inside both ends so that the guard panel rotates about 90 degrees to cover the tape pull-out portion.
It is rotatably attached to the cassette case body via the.

Both sides 2A of the slider are bent in a C shape, and the bent edges are guided by the sliding grooves 5 on both sides of the cassette case body, and can be slid between the front end and the rear end where the guard panel is provided. It is provided in. As shown in FIG. 1, the slider closes the hub hole for rotating the hub and closes the lower surface of the tape pull-out portion when pushed out toward the guard panel. When the slider is moved in the direction of arrow A, the through hole 6 opened at the hub hole position opens the hub hole. In this slider, lock holes 8 are opened at both ends of a groove 7 provided on the lower surface so that the slider can be reliably stopped at the open or closed position. A slider lock 9 provided on the cassette case is elastically pushed out into the lock hole, thereby restricting the movement of the slider.

The slider lock 9 has a tip end formed in a mountain shape, and although not shown, the tip end of the slider lock 9 is elastically elastic by a spring material.
Have been pushed out. When the slider lock 9 is pushed in the direction of the arrow B, the locked state of the slider is released and the slider can move back and forth.

Further, the slider can be elastically pressed to the guard panel side by a spring material to ensure the closed state.

The guard panel is rotated in the direction of arrow C and opened.

The magnetic tape in-cassette wrapping device shown in the plan view of FIG. 1 to FIG. 9 pulls out and adsorbs a leader tape from a cassette case mounted at a fixed position by a supporting means (not shown), Holding means for adsorbing the tip of the tape, cutting means 10 for cutting the leader tape and magnetic tape adsorbed by this holding means, splicing tape attached to the cut leader tape and magnetic tape, and connecting both tapes Connecting means 11 and rotating means (not shown) for rotating the hub 64 in the cassette case to wind the magnetic tape around the hub 64, and a temporary fixing member 13 for holding the cassette case in which the magnetic tape is wound. A transfer arm 14 for transferring the cassette case to the temporary fixing member 13,
A stopper releasing member for releasing the lock of the slider of the cassette case held by the temporary fixing member 13 and a closing member for moving the slider to the guard panel side are provided.

The temporary fixing member 13 of the cassette case is shown in FIGS. 3 to 5. The temporary fixing member 13 includes a mounting base 15 of the cassette case, an upper / lower base 16 to which the mounting base 15 is fixed, and an upper / lower base 16.
It is composed of a vertical cylinder 17 for moving up and down.

As shown in FIGS. 4 and 5, the mounting table 15 has a horizontal upper surface so that the cassette case can be horizontally mounted thereon, and two positioning protrusions 18 are provided. The positioning projection 18 is fitted into the positioning recess 57 (FIG. 1) of the cassette case to hold the cassette case in place. This platform 15
The two arms extend to both sides of the cassette case as shown in FIG. 4 so that the slider can be opened and closed while the cassette case is placed and the cassette arm can be chucked by the transfer arm 14. Has a part 19 and
The arm portions 19 are arranged slightly inward from both sides of the cassette case.

The lower surface of the cassette case on the mounting table 15 is pushed by the closing member of the slider when the slider is opened and closed. In order to prevent the cassette case from being lifted from the mounting table 15 in this state, it is possible to equip the mounting table with a cassette case clamping mechanism. However, as shown in FIG.
The upper surface of the cassette case can be pressed by 14 to prevent the cassette case on the mounting table 15 from being pushed up. Therefore, the mounting table 15 does not necessarily need to clamp the cassette case, and the mounting table shown in FIGS. 3 to 5 does not include a cassette case clamping mechanism.

The upper and lower pedestals 16 are attached to the main body via a guide 20 so as to be vertically movable, and move the pedestal 15 up and down in parallel. The slider of the cassette case on the mounting table 15 is opened and closed at the position where the upper and lower table 16 is raised, and in this state, the cassette case is sent from the mounting table 15 to the transfer arm 14 and, conversely, is transferred from the transfer arm 14. Stand
The cassette case is sent to 15. At the position where the upper and lower pedestals 16 are lowered, the cassette case in which the magnetic tape is not wound is sent to the mounting base 15, and the cassette case in which the magnetic tape is wound and the slider is closed is ejected.

The upper and lower cylinders 17 are themselves fixed vertically to the body,
The tip of the rod is fixed to the upper and lower base 16.

2 and 3 show a supply means 21 for supplying the stacked cassette cases to the mounting table 15. The supply means 21 includes a supply cylinder 22 that vertically stacks cassette cases, and a cassette case 1 from the lower edge of the supply cylinder 22.
An extruding member 23 that extrudes each one and sends it to the mounting table, and an extruding cylinder 24 that horizontally reciprocates the extruding member are provided.

The supply cylinder 22 is provided with a delivery slit wider than the thickness of the cassette case at the lower end so that one cassette case can be taken out from the lowermost stage.

As shown in FIG. 3, the push-out member 23 is provided with a concave recess on the top surface of the front end, on which the cassette case is placed, and in a state where one cassette case is pushed toward the mounting table 15, the supply cylinder
The rear part has a slightly higher horizontal shape so that the upper cassette case does not drop from 22. The extruding member 23 is attached to the main body via a guide 25 so as to be horizontally movable, and is connected to the rod tip of an extruding cylinder 24 fixed horizontally to the main body.

The transfer arm 14 is, as shown in FIGS. 2 and 6,
A rotating shaft 26 that is rotatably supported vertically in the main body,

And the top of the cassette case hit the positioning piece
It consists of 30 and.

The rotating shaft 26 is rotated at a pitch of 180 degrees by a driving means (not shown), and is vertically moved by a predetermined height from the cassette case supply / discharge position to the rotation position.

As the clamping cylinder 28, any cylinder that can clamp the cassette case by translating or slightly rotating the clamping piece 29 can be used.

As shown in FIG. 2, the sandwiching piece 29 is formed in a four-claw shape that sandwiches both longitudinal ends of the cassette case. The tip of the sandwiching piece 29 is bent in a U shape so that the cassette case can be securely sandwiched.

By the way, the sandwiching piece 29 sandwiches the cassette case with the slider opened, and transfers it from the mount 15 of the temporary fixing member to the winding position 31 of the magnetic tape. Therefore, the sandwiching piece 29 is preferably sandwiched by holding the slider of the cassette case in the open state. As described above, the slider of the cassette case has the slider lock 9 with the lock hole 8 in the open state.
It has been pushed out and is blocked from moving. However, when the locked state is released for some reason, the slider may be closed or may be slightly closed from the completely open position. The cassette case in which the slider has moved from the open position to the closed position has a drawback of causing malfunction in the winding position. As shown by the chain line in FIG. 1, by sandwiching the cassette case at the position where the sandwiching piece 29 hits the end of the opened slider, it is possible to prevent the slider from moving in the closing direction. Therefore, preferably, the width and position of the sandwiching piece 29 are determined so as to hit the end of the open slider.

The apparatus shown in FIGS. 3 to 5 has an opening / closing member 32 in which a stopper releasing member and a slider closing member are integrated.

Is provided with a protrusion 36 that is hooked in the lock hole 8 to open and close the slider. The protrusion 36 is pushed into the lock hole 8 of the slider and hooks the slider to move in the opening / closing direction with the cassette case placed on the mounting table 15. The ridge 35 presses the bottom of the groove 7 of the slider to push the slider lock 9 into the lock hole 8 to release the locked state. Therefore,
The slider is opened and closed by moving the moving member 33 horizontally.

This moving member 33 is attached to the upper / lower base 16 via a guide 37 so as to be movable in the horizontal direction.
It is fixed to the tip of the rod of a horizontal cylinder 34 which is fixed horizontally. Further, the moving member 33 penetrates the upper and lower pedestals 16 in a non-contact state so as not to hit the upper and lower pedestals 16 and the mounting pedestal 15 when horizontally moving.

The temporary fixing member 13, the transfer arm 14, the stopper releasing member, and the closing member shown in FIGS. 2 to 7 are moved to the winding position by opening and closing the slider of the cassette case in the next operation. Bring in and discharge.

16 is at the descent position indicated by the chain line, and the cassette case is fed directly above the mounting table 15.

The mounting table 15 rises to mount the cassette case on the mounting table 15, and further to the solid line position. The extruding member 23 is formed so as to hold both side edges of the cassette case so as not to hit the mounting table 15 that rises, and between the extruding members 23,
The platform 15 rises. With the platform 15 raised, the transfer arm 14 is directly above the platform 15, the transfer arm 14 is in the lowered position, and the contact piece 30 contacts the upper surface of the cassette case.
The cassette case is temporarily fixed by the contact piece 30 and the mounting table 15, and the clamping piece 29 clamps the cassette case. In this state, the positioning protrusions 18 of the mounting table 15 are guided to the positioning recesses 57 of the cassette case, and the cassette case is temporarily fixed in place.

The rod of the horizontal cylinder 34 is pulled in, and the moving member
33 opens the slider.

The rotation shaft 26 of the transfer arm 14 rises, lifts the cassette case from the mounting table 15, rotates 180 degrees, and then descends to carry the cassette case to the magnetic tape winding position. Before the transfer arm rotates by 180 degrees, if there is a cassette case already wound with the magnetic tape at the winding position, the cassette case already wound with the magnetic tape is carried from the winding position onto the mounting table 15.

The rod of the horizontal cylinder 34 is pushed out, and the slider is closed by the moving member 33.

The sandwiching piece 29 releases the sandwiched state of the cassette case,
The cassette case with the slider closed is removed from the mounting table 15, and the mounting table 15 descends. The cassette case taken out from the mounting table 15 is manually carried out by the grip of the cassette case or carried out by an automatic sending mechanism.

Then, the operations from to are repeated.

In the embodiment shown in FIGS. 2 to 7, the cassette case with the slider closed is sent to the mounting table 15, where the slider is opened and carried to the winding position of the magnetic tape. According to this structure, the slider is closed for a long time, and the bit error due to the adhesion of dust can be most effectively prevented. However, the slider does not necessarily have to be opened on the platform,
It is also possible to supply to the mounting table in the open state, or to open the slider during the supply.
