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.

This method has the disadvantage that the processing takes time and productivity cannot be improved. As a bag counterfeit that solves this drawback, the cut point of the leader tape is fed to two reels close to each other, and after connection, the tape between the reels is cut and the tape is separated. We developed a method to connect leader tapes between the cables.

Since this device connects the cut points of the leader tape to two reels at the same time, the efficiency of connecting the leader tapes can be increased. At the same time as cutting the leader tape, the cut ends are fixed to reels close to each other.Hishinao arranges multiple pairs of two reels at regular intervals on a rotating disc. It is better.

That is, each time a leader tape is fixed to a pair of reels, it is preferable to rotate the disc by a certain angle and fix the leader tape to the next IJ reel. According to this method, the length of the leader tape is determined by the distance between each pair of reels attached to the disc. That is, once the length of the leader tape is determined, the size of the disk and the spacing between each pair of reels are determined. For this reason, long leader tapes are connected using small discs, and in this state many pairs of reels cannot be attached to one disc, resulting in a large device. ■Purpose The present invention was developed with the aim of eliminating these drawbacks of conventional devices.An important purpose of the present invention is to miniaturize the overall shape of the device so that a long leader tape can be fixed. To provide a device for fixing both ends of a leader tape to a reel with high throughput.

■Configuration Embodiments 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. A tape fixing means is provided for fixing the leader tape 2 to the tape feed roller fed into the tape fixing position.

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

The rotation holding unit 3 is rotatably supported on a base via a central shaft 4, and six pairs of reels 1 are attached at fixed 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 driving member 5 rotates the rotation holding member 3 at a rotation angle of a constant pitch.

Since the rotation holding member 3 shown in FIG. 1 has six pairs of reels 1 mounted at 60 degree intervals, the driving member 5
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 position where the leader tape 2 is fixed. Send it in. 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 IJ reels 1, and a cutter 6 that cuts the leader tape 2 between a pair of approaching IJ reels 1, and a cutter 6 that cuts the leader tape 2 between a pair of approaching IJ reels 1, and a cutter 6 that cuts the leader tape 2 between a pair of IJ reels 1 that are close to each other. It includes a press-fitting member 8 for fixing, and a temporary fixing member 9 for adsorbing the cut end of the IJ-dar tape 2.

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 insertion member 8 fixes the end of the leader tape 2 to the reel 1 by inserting the clamp 10 into the drum groove 13 provided in the hub 7 of the reel.

At the end of this press-fitting member 8, a recess 11 is formed into which the clamp 10 is sucked.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 This is filled with iron, or an air hole for suction is provided on the surface of the recess 11 so that air can be adsorbed. The clamps 10 are inserted together into a pair of reels 1 that are close to each other. Therefore, the press-fitting member 8 in FIG.
are arranged above the hub 7 of each reel 1,
The two pieces are lowered and raised together. The reciprocating movement of the injection member 8 is caused by the cylinder 12. Saddle fitting groove 1 of hub 7 with clamp 10
The cut end of the leader tape 2 which is attached to the leader tape 3 is guided to the joining groove 13 of the hub 7 by a temporary release member 9. The temporary fastening member 9 is attached to the suction surface 14 (lower surface in FIG. 2) of the leader tape 2.
An air hole 15 is connected to a vacuum source via a solenoid valve (not shown).

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 attachment section 9 attracts the leader tape before it is cut, and after cutting, separates the cut end and sends it to the hub 7. The temporary stop member 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.
When the leader tape is clamped in the iron groove 13 at 0, 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 most of the leader tape is not attached to the hub. Insert the iron groove 1 so that it does not get pulled in.
3, and is moved to a position that is slightly extended forward. The temporary fixing member 9 adsorbs the leader tape 2 at a position slightly retreating from the cut end so that the cut end portion of the leader tape 2 can be press-fitted into the carry-in groove 13 by 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 is determined, and the diameter of the rotation holding member cannot be made that small. A leader tape meandering means 18 that reduces the diameter of the rotation holding member 3 without shortening the overall length of the leader tape 2 connected to the reel is shown in FIGS. 1, 5, and 6. .

This meandering means 18 includes a pair of reels located at the tape fixing position pupil for fixing the leader tape 2 to the reel, and a front reel disposed adjacent thereto to which the leader tape is already fixed. A push roll 19 is arranged so as to be able to come in and out at right angles between the push rolls 19, two pinch rolls 20 are arranged in the rotation holding section village 3 to be located on both sides of the push roll 19, and Radar tape 2 pressed by roll 19
It is equipped with a locking pin 21 for hooking. Push roll 1
9, as shown in FIG. 4, two rolls are arranged spaced apart in the circumferential direction of the rotation holding member 3, and are connected to the tip of the rod of the cylinder 22.

The roller roll 20 makes the leader tape 2 pressed by the push roll 19 meander to increase the length of the leader tape.

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 device configured as described above for fixing the dart tape 2 to the reel 1 operates as follows.

5. First, in FIG. 1, on the left side of the rotation holding member 3, there is a 2
A number of reels 1 are installed.

The two reels 0 and 1 are not fed together as they approach each other, but the two adjacent reels 1 are placed apart from each other, and then the rotation holding member 3 rotates at a pitch of 60 degrees. Attach 6 pairs of reels and tape leader tape 2.
Pull it out until it is fixed with tape.

Figure 1 Temporary stopper member 9 descends and adsorbs leader tape 2. The temporary opening members 9 that have attracted the leader tape are in such a position that they approach each other before adsorbing the leader tape. hill
In this state, the cutter 6 descends to cut the leader tape 0, and after cutting, rises and waits at its original position. , and bring the cut end of the leader tape close to the reel hub 7 as shown by the solid line in FIG.

In this state, the insertion member 8 that holds the clamp 10 in the recess is lowered, the clamp 10 is carried into the iron cabinet, and the leader tape 2 is attached to the hub 7.

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

After that, the push roll 19, which is the rolling means 18, is pushed out to make the leader tape 2 meander. In this state, the locking pin 21 is retracted. After the countersunk pin 21 is pushed out, the push roll 19 is retracted, and the IJ-dartape 12 maintains its meandering state. (2) Thereafter, the leader tape 2 is fixed to the reel 1 by repeating the steps shown in FIGS.

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 As mentioned above, the device that fixes both ends of the leader tape to the reel is configured such that the reel is at the fixed position of the leader tape, and the rotating holding member rotates when the leader tape is already fixed and feeds out the tape from the fixed position. A meandering means for the leader tape is disposed between the decorative reel and the meandering means fixes the leader tape to the reel in a meandering state.

Therefore, the total length of the leader tape is not determined by the distance between each pair of reels, and the total length of the leader tape can be made longer than the distance between each pair of reels. Therefore, long leader tapes can be connected and fixed by shortening the distance between the reels, the diameter of the rotation holding member to which multiple pairs of reels are attached can be reduced, and the entire device can be made compact. Since the pair of reels are arranged on the circumference and the leader tape is fixed to the pair of reels together, the leader tape can be extremely efficiently and quickly fixed.
