Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates primarily to a device for fixing a leader tape to a reel for connecting a videotape to a reel.

■ Prior art video tapes are not connected directly to the reel, but are connected to the reel via a leader tape.

Therefore, it is necessary to fix a certain length of leader tape at both ends to the reel around which the videotape is wound, with a pair of leader tapes. Conventionally, one end of a leader tape was connected to one reel, the leader tape was cut to a certain length, and the rear end was fixed to another reel.

According to this method, the overall shape of the device becomes larger, and
There was a point where processing took time and productivity did not improve. As a device that solves this drawback, the cutting point of the leader tape is connected to two reels that are close to each other, and the tape between the reels is cut after the leader tape is connected. We developed a method for connecting tapes. In this type of bag counterfeiting, the cut points of the leader tape are connected to two reels at the same time, so the efficiency of connecting the leader tapes is high. It is difficult to cut the cut end so that it does not protrude at all, and there is also the disadvantage that the short IJ-dar tape that is cut off between the reels is wasted.
■Purpose The present invention was developed with the aim of eliminating these drawbacks of conventional devices. To provide a bag straightener for fixing both ends of a leader tape to two reels, which can connect the cut end of the leader tape in a state where it does not protrude from the hub of the reel.

■Mechanism Examples of the present invention will be described below based on the drawings.

The device for fixing both ends of a leader tape to two reels shown in FIG. The leader tape fixing means is provided for fixing the leader tape 2 to the roller fed into the fixing position.

The reel supply means includes a disk-shaped rotation holding member 3 that rotates in a vertical plane, and a driving member 5 of this rotation holding portion village 3.

The rotation holding member 3 is rotatably supported on a base via a central shaft 4, and six pairs of IJ rules 1 are attached at regular intervals on the circumference around the shaft 4 at attachment/detachment positions. has been done.

A pair of reels 1 mounted close to each other are close to each other so that the cut ends of the leader tape 2 can be fixed together.

However, both ends of one leader tape 2 are not fixed to a pair of reels 1 that are close to each other, but are adjacent to each other and are separated from each other, or are fixed to the reels 1. The drive unit 5 rotates the rotation holding member 3 at a rotation angle of a constant pitch.

Since the rotation holding member village 3 in FIG.
is rotated at a pitch of 60 degrees, and after the cut ends of the leader tape 2 are fixed to the adjacent pair of reels 1, the adjacent pair of reels 1 are moved to the fixed position of the leader tape 2. send to. Therefore, when fixing the leader tape 2 to the reel 1, the driving member 5 stops the rotation of the rotation holding member 3, and after the leader tape 2 is fixed to the reel 1, rotates it by 60 degrees.

That is, the driving member 5 is operated in synchronization with the operation of the fixing means for the leader tape 2. As shown in FIG. 2, the means for fixing the leader tape 2 includes a cutter 6 that cuts the leader tape 2 between a pair of approaching reels 1, and a press fit that fixes the cut leader tape machine to a reel hub 7. Part 8
and Sekibe Village 9, which temporarily attaches the cutting machine for leader tape 2.
It is equipped with

The cutter 6 has a cutting edge 6a at the lower end so as to cut the leader tape 2 between the approaching reels 1, as shown in FIG.
is placed in a position where it is pressed perpendicularly to the surface of the leader tape.

As shown in FIG. 4, the press-fitting member 8 fixes the end of the leader tape 2 to the reel by press-fitting the clamp 10 into the slot-in groove 13 provided in the hub 7 of the reel.

At the tip of this insertion member 8, a recess 11 is formed to which the clamp 10 is attracted.For example, the clamp 10 is fed into the recess 11 via a parts feeder, and the clamp 10 fed into the recess 11 is placed here. The surface of the recessed building 11 is filled with iron, or air holes for suction are closed on the surface of the recessed building 11 so that air can be adsorbed. The clamps 10 are pressed together into two pairs of reels that are close together. Therefore, two insertion members 8 in FIG. 2 are disposed above the hub 7 of each reel 1, and two
The pieces are lowered and raised together. The reciprocating movement of the press-fitting member 8 is caused by the cylinder 12. The clamp 10 is inserted into the iron groove 13 of the hub 7.
The cut end of the leader tape 2 sandwiched between the temporary opening members 9
It is guided to the carry-in groove 13 of the hub 7.

The temporary fixing member 9 is attached to the suction surface 14 (second
An air hole 15 is opened on the bottom surface (in the figure), and this air hole 1
Although not shown, 5 is connected to a vacuum source via a solenoid valve.

When the solenoid valve is opened, air is sucked through the air hole 15, and in this state, the leader tape 2 is attracted to the suction surface. When the solenoid valve is closed, the suction of air is stopped and the suction state of the leader tape is released. .

The temporary fastening member 9 attracts the leader tape before it is cut, and after cutting, the leader tape is separated from the cutting machine and sent to the tape 7. The temporary joint section 9 shown in FIGS. 2 and 3 is driven by two cylinders 16 and 17 arranged orthogonally to each other. The leader tape 2 is moved toward the hub by cylinders 16 arranged parallel to the movement direction of the press-fitting member 8, and the cut ends of the leader tape 2 are separated by cylinders 17 perpendicular thereto. FIG. 4 shows the state in which the cut ends of the leader tape 2 are separated.

In this figure, the cut end of leader tape 2 is connected to clamp 1.
0, the leader tape is clamped in the iron groove 13, and the cut end is flush with the circumference of the hub 7, that is, the cut end of the leader tape does not protrude from the hub 7, and the leader tape is Iso-iri groove 1 so that it is hardly pulled into the hub.
3 to a position slightly extended forward. The temporary opening village 9 adsorbs the leader tape 2 at a position slightly retreated from the cutting machine so that the cut end of the IJ-dar tape 2 can be press-fitted into the European fitting groove 13 with the clamp 10. .

The length of the leader tape 2 whose ends are fixed to the two reels 1 is determined by the distance between each pair of IJ reels.

Therefore, once the total length of the leader tape is determined, the distance between each pair of reels cannot be made that short, and the diameter of the rotation holding member cannot be made small. Leader tape 2 connected to reel
A leader tape extension means 18 is shown in FIGS. 1, 5 and 6, which reduces the diameter of the rotary holding member 3 without shortening its overall length. This stretching means 18 is
Between a pair of reels at the tape fixing position where the leader tape 2 is fixed to the reel and a pair of IJ reels adjacent to this where grain is distributed and to which the leader tape has already been fixed. A push roll 19 that can be moved in and out of the
It is provided with two pinch rolls 20 arranged on the rotation holding part village 3 so as to be located on both sides of the rotation holding part 9, and a locking pin 21 for hooking the reader tape 2 pressed by a push roll 19. As shown in FIG. 4, the god roll 19 is made up of two rolls spaced apart from each other in the circumferential direction of the rotation holding member 3, and is connected to the tip of the rod of the cylinder 22.

Using the pinch roll 2, the leader tape 2 pushed by the push roll 19 is made to meander to lengthen the leader tape length.

The locking pin 21 holds the leader tape 2 in a meandering state after the push roll 19 has retreated, and is attached to the rotary holding member 3 through a cylinder 23 so as to be freely removable and removable, as shown in FIG. .

(2) Operation The apparatus configured as described above for fixing the radar tape 2 to the reel 1 operates as follows.

First, in FIG. 1, there is a 2
Attach reel 1.

Rather than supplying the two reels 1 close to each other together, the two adjacent reels 1 are installed apart from each other, and then the rotation holding member 3 is rotated at a pitch of 60 degrees. Turn it, attach the 6 pairs of reels, and pull out the leader tape 2 to the tape fixing position.

The temporarily fixed box 9 descends and adsorbs the leader tape 2. The temporary opening members 9 that have attracted the leader tape are in positions close to each other before adsorbing the leader tape. Figure In this state, the cutter 6 descends and cuts the leader tape.
After cutting, it rises and waits in its original position.

4. The temporary stopper members 9 that adsorb the cut leader tape 2 move away from each other to bring the cut end of the leader tape closer to the hub 7 of the reel as shown by the solid line in FIG.

4. In this state, the press-fitting member 8 that holds the clasp 10 in a concave position is lowered, the clamp 10 is inserted into the iron-fitting groove, and the leader tape 2 is attached to the hub 7.

After that, the press-fitting member 9 rises, and the temporary fitting member 9
releases the suction state of the leader tape 2, and the temporary fastening members 9 rise and approach each other to wait at their original positions.
When the cut end of the tape is fixed to the pair of reels, the rotation holding member 3 rotates 60 degrees and stops.

Sono: After that, the push roll 19, which is the elongating means 18, is pushed out to make the leader tape 2 meander. In this state, the locking pin 21' is also pulled in loosely. After the rigid pin 21 is pushed out, the push roll 19 is retracted, and the leader tape 12 maintains its meandering state. After that, steps 2 to 9 are repeated to fix the leader tape 2 to the reel 1.

The reel 1 to which the leader tape is fixed is taken out on the left side of the rotary holding member 3 in FIG. 1, and after the reel is taken out, a new reel is installed.

■Effect The device configured as described above for fixing both ends of the radar tape to two reels arranges a plurality of pairs of reels at predetermined intervals on the circumference of a rotating holding member, and connects one pair of reels to two reels. Since it has a structure in which the rotation holding member is rotated each time the leader tape is fixed to the
Since the cut parts of the tape are connected together to the pair of reels, the processing capacity is high.Furthermore, the temporary fixing member separates the cut parts of the leader tape from each other and moves them to a predetermined position on the hap.
Since the leader tape is connected to the hub in this state, it can be fixed so that it does not protrude from the leader tape cutting machine, and there is no wasteful cutting edge of the leader tape, and all glue is removed.
To achieve great efficiency in effectively utilizing data tape.

By aligning the cut end of the leader tape with the surface of the tape and fixing it, there is no difference in level in the magnetic tape wound thereon, and the magnetic tape can be wound in a perfect circle.
