Abstract

PURPOSE:To steadily and rapidly link a reader tape with a magnetic tape by directing the blowoff direction of air to the transfer direction of an adhesive tape, jetting air pressure from an air nozzle, correcting the direction of the cut end of the adhesive tape in a straight line shape with an air flow. CONSTITUTION:An adhesive tape 28 protruded from an absorption board 31 is lowered a little by its deadweight, but the direction of the tape is corrected by the air flow injected from the air nozzle in the transfer direction of the adhesive tape 28. A pressing member 29 which transfers the adhesive tape 28 comes down on the upper surface of the adhesive tape 28, whose direction is corrected, and absorbs the upper surface of the adhesive tape 28. At such a state, a cutter 32 is raised, and the tip of the adhesive tape 28 is cut in a regulated length, and a cut adhesive tape 28 is transferred to and linked at a part confronting a reader tape 2 with the magnetic tape. In such a way, a faulty absorption in the adhesive tape 28 is reduced extremely, and the reader tape and the magnetic tape can be linked steadily with the adhesive tape.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention is directed to an apparatus for connecting a magnetic tape through an adhesive tape in the middle of a leader tape and winding it around a hub.

B. Conventional technology A device for butting and connecting a leader tape and a magnetic tape has been developed (Japanese Unexamined Patent Publication No. 12447/1983). As shown in FIG. 13, this device adsorbs an adhesive tape S onto the surface of a drum D, cuts it into a certain length, and cuts the entire drum D with a leader tape R and a magnetic tape.
Press the adhesive tape S to the butt part,
Thereafter, the surface of the adhesive tape S is pressed with a roller (not shown) to adhere the adhesive tape S.

C9 Problems with the conventional structure In order to press the large tram D against the abutting part of the leader tape R and magnetic tape J, the leader tape R is pulled out from the cassette for a long time, and the drum D is moved by the force above the abutting part of both tapes. Also, since it is pressed with a large drum D and then pressed with a roller,
The overall mechanism is complicated, and the adsorption processing speed of the adhesive tape S cannot be shortened.

As shown in FIG.
The above-mentioned drawbacks were solved by transporting the magnetic tape to the abutment part between the magnetic tape and the magnetic tape and pressing it. However, in this method, the adhesive tape 28 is fed by a fixed length on a carriage 30, and the tip is adsorbed on a suction stand 31 and cut into a fixed length. Since the tip of the adhesive tape 28 cannot be held, the tip of the adhesive tape 28 cannot be fed out in a straight line at all times, resulting in a disadvantage that the reliability of the suction process after feeding is reduced.

The present invention was developed with the aim of further solving this problem, and an important objective of the present invention is that the cut end of the adhesive tape is held in a straight line by air flow, and the cut end of the adhesive tape is To provide a magnetic tape winding device which can perform suction processing reliably and can reliably and quickly connect a leader tape and a magnetic tape.

D. Means for Solving Conventional Problems The magnetic tape winding device shown in FIGS. 1 to 6 has a holder that pulls out and holds a leader chip 12 connected at both ends to a hub 24 around which the tape is wound. a cutting means 7 for cutting the leader tape 2 held by the holding means; a connecting means 8 for connecting the tip of the magnetic tape 6 to the cut end of the leader tape 2 cut by the cutting means 7; and a magnetic chip 16.
The hub 24 connected to the leader tape is rotatably driven to wind the magnetic tape around the hub. After a predetermined amount of tape is wound around the hub 24, the magnetic Cutting means 7 holding the tape 6
The magnetic tape 6 is cut by the cut magnetic tape 6.
The terminal end of the leader tape 2 is connected to the cut end of the leader tape 2 by a connecting means 8.

The connecting means 8 includes a suction table 31 for temporarily fixing the adhesive tape 28 that connects the leader tape 2 and the magnetic chip 16, and a reciprocating table that reciprocates with respect to the suction table 31 and sends the adhesive tape 28 to the suction table 31. 30, a driving means for the carriage 30,
It has a supply member for the adhesive tee 128 with an air nozzle N directing the adhesive tape 28 in the transport direction.

In the process of approaching the suction table 31, the reciprocating table 30
8 is temporarily fixed, and in the process of separating from the suction table 31,
The suction table 31 has a suction means for canceling the suction state of the second day.
has suction means that releases the tape suction state in the process in which the carriage 30 approaches and suctions the adhesive chip 128 in the process in which the carriage 30 leaves the suction table 31.

The air nozzle N is disposed near the cut end of the adhesive chip 128, somewhat behind the cut end, and close to the surface of the adhesive chip 128, and the air nozzle N is blown out in a direction opposite to the adhesive chip 128. The air nozzle N injects pressurized air to correct the direction of the cut end of the adhesive tape 28 in a straight line with the air flow.

E. Operation, function, and effect The operation and function of the supply member of the preferred embodiment of the present invention shown in FIGS. 1 to 3 are as follows.

With the suction table 31 suctioning the adhesive tape 28, the carriage 30 retreats to the position shown in FIGS. 1 and 2. At this time, the carriage 30 does not adsorb the adhesive chip 128. After that, the reciprocating table 30 suctions the adhesive tape 28, and the suction table 31
approach. At this time, the suction stand 31 does not suction the adhesive tape 28. With this operation, the tip of the adhesive tape 28
As shown in the figure and FIG. 3, it protrudes from the tip of the suction table 31.

The adhesive tape 28 protruding from the suction table 31 will fall a little due to its own weight if it remains as it is, but its direction will be corrected in a straight line by the air flow blown out by the air nozzle N in the direction in which the adhesive tape 28 is transported.

The pressing member 29, which transfers the adhesive tape 28 to the upper surface of the adhesive tape 2B whose direction has been corrected linearly by the air flow, descends and adsorbs the upper surface of the adhesive tape 2B.

In this state, the cutter 32 rises, cuts the tip of the adhesive tape 28 to a certain length, and carries the cut adhesive chip 128 to the abutting portion of the leader tape 2 and the magnetic tape to connect them.

The direction of the bonding tool 12 is corrected to a straight line by the air flow.
8, even if it protrudes from the suction part, it can be reliably suctioned,
The adhesion failure of the adhesive tape 28 is minimized, and the adhesive tape can reliably connect the leader tape and the magnetic tape.

1 is connected to the rods of the left and right cylinders 22, the left and right cylinders 22 are connected to the rods of the upper and lower cylinders 23, and the upper and lower cylinders 23 are fixed to the frame.

The moving table 20 has a guide 25 that extends forward and backward, left and right, and up and down.
．． 26. Translated by 27.

The cutter 19 cuts the tape in the following operation.

As shown in Fig. 1, the cutter 19 is positioned deeper than the tape surface.
Move to the right and move to the cutting position in the center of the tape. At this time, the moving table 20 is in the raised position.

(2) Thereafter, while the cutter 19 remains raised and lowered, it is moved forward to penetrate into the upper surface of the tape 2 or 6.

- Lower the cutter 19 to the tape cutting surface.

(2) The cutter 19 moves back and cuts the tape 2 or 6.

As shown in FIGS. 1 and 6, the connecting means includes a pressing member 29 that attracts the adhesive tape 28 and presses it onto the upper surfaces of the leader tape 2 and the magnetic chip 16 to connect both tapes. It consists of three cylinders (not shown) that move the pressing member 29 back and forth, left and right, and up and down, and a supply member that supplies the adhesive tape 28 to the lower surface of the pressing member 29.

The pressing member 29 has the same structure as the movable table 20 of the cutting means, has three cylinders and three sets of guides, and has the adhesive tape 28 adsorbed on its lower surface. and move it to the right until it is on the tape connection line.

■Leave the pressing member 29 in the raised position and move forward to the top of the tape.

(2) The pressing member 29 descends and presses the adhesive chip 128 against the cut ends of the leader tape 2 and magnetic tape 6, thereby connecting both tapes 2 and 6.

(2) The pressing member 29 rises.

(2) The pressing member 29 retreats.

(2) The pressing member 29 moves to the right and returns to the standby position.

Thereafter, each time the leader chip 12 and the magnetic tape 6 are connected, the operations 1 to 2 are repeated, and the adhesive chip 128 is bonded to the upper surface of both tapes 2 and 6 to connect both tapes.

Adhesive tape 2 cut to a predetermined length is placed on the lower surface of the pressing member 29.
The supply member for supplying the adhesive tape 8 includes a carriage 30 that pulls out the adhesive tape 28 wound on a roll, a suction table 31 that is located between the carriage 30 and the pressing member 29, and that sucks the lower surface of the tip of the adhesive tape 28. , and a cutter 32 for cutting the adhesive tape 28 at the rear end surface of the pressing member 29.

The pressing member 29 in the standby position, the suction table 31 and the reciprocating table 3
0 are located on the same plane, and each has an air suction hole (not shown) opened in the bottom surface so that the adhesive tape 28 can be sucked onto the bottom surface with a suction means. The bore is connected to a vacuum source via a control valve.

As shown in FIGS. 2 and 3, the suction table 31 directs the adhesive tape suctioned to its lower surface and the adhesive chip 128 sent out by the carriage 30 in a straight line in the tape transport direction, as shown in FIG. The adhesive tape 28 has an air nozzle N that extends horizontally and blows pressurized air horizontally toward the tip of the adhesive tape 28 so that it can be reliably attracted to the lower surface of the pressing member 29.

The air nozzle N uses the air flow blown out from the air nozzle N to straighten the direction of the adhesive chip 128, which is about to sag due to its own weight. Therefore, the air nozzle N injects a narrow beam-shaped air stream to a portion approaching the surface of the adhesive chip 128 in parallel thereto.

The timing at which the air nozzle N injects air is determined at the timing at which the adhesive tape 28 protrudes from the suction table 31 in the transport direction,
Alternatively, it injects air continuously all the time.

The carriage 30 adsorbs the adhesive tape 28 on its lower surface and moves forward from right to left in FIGS. . When the carriage 30 retreats from left to right, the adhesive tape 2
Does not absorb 8. In this state, the tip of the adhesive tape 28 is attracted to the suction table 31.

The cutter 32 rises with the pressure member 29 and the suction table 31 adsorbing the adhesive tape 28, and cuts the adhesive tape 28 at the rear end surface of the pressure member 29.

In the step in which the connecting member connects the leader tape 2 and the magnetic tape 6, the cutter 19 that cuts the leader tape 2 or the magnetic tape 6 is on standby outside the path of the pressing member.

By the way, the present invention is not limited to the structure in which the pressing member 29, the suction stand 31, and the carriage 30 adsorb the adhesive tape 28 on their lower surfaces and transport the adhesive tape 28 horizontally. The apparatus shown in FIG. 6 can also be used upside down. in this case,
The pressing member 29, the suction table 31, and the carriage 30 are in a state in which the adhesive tape is sucked onto their upper surfaces and the adhesive tape is transferred horizontally.

Therefore, when the adhesive tape transferred in this state hangs down due to its own weight, it is placed on the upper surface of the pressing member and is prevented from hanging down significantly. However, even in this state,
It is preferable to use the airflow to extend the adhesive tape linearly in the transport direction to reduce sagging.

Also, when the left side is facing down in Figure 3, the adhesive tape 28
is transported directly below by its own weight, and it appears that no deformation occurs due to its own weight. However, when the adhesive tape 128 is wound into a roll, the adhesive tape itself has a tendency to curl, which causes the adhesive tape to curve. The airflow can straighten the adhesive tape by correcting deformations due to its own weight or curling.

The air nozzle N is arranged at a position slightly rearward from the cut end of the adhesive tape 28 and close to the surface of the adhesive tape 28 so as to extend the tip end of the adhesive tape 28 linearly in the transport direction. The air is blown out in the direction in which the adhesive tape 28 is transported.

In FIGS. 2 and 3, the air nozzle N is attached to the suction table 31.
Fixed.

Incidentally, the suction table 31 can also be used as the adhesive tape moving table 29, but in this case, as shown by the chain line in FIG. After cutting the adhesive tape 2 days with the cutter 32', the cut adhesive tape 128 is carried to the abutting part of the leader tape and the magnetic tape by the suction stand 31 and pressed.

The mechanism of the moving table 29 can be used as is for the structure of transporting the suction table 31 to the abutting portion of the leader tape 2 and the magnetic tape 6.

In this case, the operation of the suction table 31 and the carriage 30 is such that, as shown in FIGS. is carried to the lower surface of the suction table 31, and in this state, air is injected from the air nozzle N to hold the adhesive tape 28 in a straight line, so that the adhesive tape 28 is attracted to the lower surface of the suction table 31. Thereafter, with the suction table 31 suctioning the adhesive tape 28 and the carriage 30 not suctioning the adhesive chip 128, the carriage 30 is moved back as shown in FIG. 12, and both of them are suctioning the adhesive tape 28. Then, cut the adhesive tape 28 with the cutter 32'.
is cut, the suction table 31 carries the adhesive chip 128 to the position where the connecting tapes meet, and then returns to the position shown in FIG. 11 again, and the movement of the carriage 30 approaching is repeated.

(2) The cutter 19 enters between the first and second holding members 11 and 120 and cuts the leader chi 12.

In this state, the first and second holding members 11.12 hold the leader chi 12 in an 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 so that its upper surface is on the same plane. do.

Even in this state, the first, second, and third holding members 11
．． 12 and 13 attract the leader tape 2 and the magnetic tape 6.

(2) The leader chip 12 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 at a connecting position.

■Then, the first and third holding members 11.13 release the adsorption state, and the hub 24 to which the leader tape 2 connected to the magnetic tape is fixed is rotated by the rotating means, and the magnetic tape 6 is moved into the cassette case 1. get involved in

■After a predetermined length of magnetic tape 6 is wound up, the hub 24
The rotation of the magnetic tape 6 is stopped, and the magnetic tape 6 is attracted by the first and third holding members 11, 13.

(2) The cutter 19 enters and cuts the magnetic tape 6 between the first and third holding members 11.13.

- The third holding member 13 attracts the magnetic tape 6 and moves to the standby position shown by the solid line in FIG. 4, and the second holding member 12 moves from the standby position shown by the solid line in FIG. It moves to a position adjacent to the first holding member 11 shown by the chain line in FIG.

[Phase] The terminal 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 are connected by the connecting means.

(2) The hub 24 is rotated and the slack tape is drawn into the cassette case 1.

■Replace the cassette case l with another one that does not have magnetic tape wrapped around it.

Thereafter, repeat this process to wind the magnetic tape into the cassette case.

In the apparatus of the present invention shown in FIG. 6, the cassette case is placed vertically with its opening facing downward, and the leader tape pulled out from the cassette case is surrounded by the cassette case, a guard panel, and a holding member. This prevents dust from adhering to the tape.

In FIG. 6, it is also possible to turn the entire device upside down, that is, with the front end of the cassette case facing upward, and to cover and surround the upper surface of the leader tape pulled out to the opening of the cassette case with a holding member. .

Regardless of the direction in which the cassette case is held, 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 will be surrounded by the cassette case, the holding member, and the guard panel, and foreign objects will be present on the leader tape. adhesion is prevented.

Therefore, the present invention does not limit the posture in which the cassette case is held.

The cassette case shown in Figure 8 has a double bottom plate, and the outer bottom plate is slidably attached to the case body, and when the outer bottom plate is removed from the cassette case, there is a frontage on the bottom of the cassette case. By closing the hole in the hub and closing the guard panel, the entire magnetic tape can be housed in a completely closed cassette case. A cassette case with this structure can minimize the amount of dust that adheres to the magnetic tape after it is wound up.
