Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for peeling a tape piece partially adhered to a sheet-like material.

[Conventional technology]

Generally, when a film such as a color film is automatically developed, one end of the film is inserted through a piece of tape into a synthetic resin sheet leader having a square hole engageable with a feed sprocket incorporated in the developing device. And the reader is sent to the developing device in advance.

The processed film taken out of the developing device is
Next, it is cut near the connecting portion to the tape piece and separated from the leader. At this time, the tape piece and the film piece remain on the leader, while the leader is used in an inverted manner, so that the tape piece needs to be peeled from the leader.

[Problems to be solved by the invention]

Conventionally, when the tape piece was peeled off, the tape piece was manually peeled off, which was extremely troublesome.

In view of the above, the present invention has been made to solve the above-described inconvenience, and to provide a tape peeling device capable of automatically peeling a tape piece partially adhered to a sheet-like material such as a leader. It is an issue.

[Means for solving the problem]

In order to solve the above problems, in the present invention,
In the transfer path of the sheet-like material having a part of the tape piece adhered to one side of the outer periphery, a support for the sheet-like material is provided, and a rotating shaft is arranged below the support-side of the support for the sheet-like material. The rear ends of the pair of arms are rotatably supported by a pair of disks fixed to both ends of the rotating shaft, and the leading end of the arms supports a clamp device for holding the tape of the sheet-like material. A first stopper for stopping and holding the arm in a state where the arm is transferred above the rotation shaft and the clamp device faces the transfer path of the sheet-like material is provided on the sheet-like material loading side of the arm; The elastic force of the spring is applied to the arm in the direction in which the arm contacts, and the disc has
When the arm is tilted rearward by a predetermined angle in the rotation direction in a state in which the arm is in contact with the first stopper, a configuration is provided in which a second stopper is provided to come into contact with the arm.

[Action]

The sheet-like material where the tape piece remains is sent along the transfer path with the tape piece as the rear side, and when the sheet-like material is stopped by being supported by the support table, the rotating shaft rotates, and at the same time the clamp device operates. Hold the tape piece. Since the arm supporting the clamp device is pressed against the first stopper by the spring, the rotation of the rotation shaft causes the arm to rotate around the connecting portion with respect to the disk and to move toward the rear side in the rotation direction of the disk. As it falls, the clamping device moves below the transfer path.

When the arm is tilted by a predetermined angle while being supported by the first stopper, the second stopper hits the arm, and the arm rotates around the rotation axis together with the disk while being supported by the second stopper. At this time, since the clamp device rotates below the support table, the piece of tape clamped by the clamp device is pulled down obliquely downward of the sheet-like material in a stopped state, and is separated from the sheet-like material. .

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 3, a leader L as a sheet-like object to which a film F is connected by a tape piece T.
Is horizontally transferred from left to right in FIG. 2 by a transfer device not shown. In the transfer path, a support table 1 for supporting the reader L and a pair of feed rollers 2
In the transfer direction.

The support base 1 is provided with a notch 3 at the rear of the loading side of the leader L, through which the tape piece T adhered to the leader L can pass. A cutter device 4 is provided on the loading side of the support table 1.
The cutter device 4 is activated when the leader L is fed onto the support base 1 and stopped, and cuts the film F connected to the leader L in the vicinity of the connection to the tape piece T.

A support frame 5 is provided below the cutter device 4 and the support base 1.
And a pair of side plates 6 provided on both sides of the support frame 5.
Thus, both ends of the rotating shaft 7 are rotatably supported. The rotating shaft 7 is rotated in the direction of the arrow in FIG. 2 by the operation of a driving device (not shown).

A pair of disks 8, 8 are attached to both ends of the rotating shaft 7, and the rear ends of a pair of arms 10, 10 are fixed to a support shaft 9 extending between the disks 8, 8. A clamp device 11 is supported by the distal ends of the arms 10,10.

The clamp device 11 is composed of a fixed bar 12 passed between the distal ends of the pair of arms 10, 10 and a movable bar 13 disposed inside the fixed bar 12, and the opposing surfaces of the two bars 12, 13. Tape holding pads 14 and 15 are attached to the tape.

Both ends of the movable bar 13 are movably supported along ridges 16 formed on inner surfaces of the pair of arms 10, 10.
The movable bar 13 is fixed to the fixed bar 12 by the operation of the cam mechanism 20.
, And is moved away from the fixed bar 12 by the elastic force of a spring 21 provided between the fixed bar 12 and the fixed bar 12.

Here, the cam mechanism 20 is provided with gears 22 and 23 that mesh with the rotating shaft 7 and the supporting shaft 9 to transmit rotation to the rotating shaft 7 to the supporting shaft 9. A cam follower 25 supported by the movable bar 13 is brought into contact with the outer periphery.

When the clamp device 11 faces the transfer path of the reader L, the arm 10 is positioned vertically above the rotary shaft 7 and is in a vertical state. A first stopper 31 having a rod shape is provided on the reader loading side of the arm 10 in the vertical state. The first stopper 31 is provided above the side plate 6 of the support frame 5. 1st stopper
A spring that deflects the arm 10 in the direction that comes into contact with 31
32 is supported by the end of the support shaft 9. For this reason,
When the disk 8 rotates in the direction of the arrow in FIG. 2, the arm 10 falls from the vertical state toward the rear in the rotation direction in a state of contacting the first stopper 31, and when the arm 10 is inclined by a predetermined angle, the arm 10
The second stopper 33 that contacts the disk 8 is attached to the disk 8.

The tape peeling device shown in the embodiment has the above structure,
When the reader L is transferred onto the support 1, the clamp device 11 is held so as to face the transfer path of the reader L.

The reader L is fed onto the support 1 from between the fixed bar 12 and the movable bar 13 of the clamp device 11 with the film F connected to the reader L on the rear side.

When the leading end of the leader L is fed between the feed rollers 2 and the tape piece T connecting the leader L and the film F faces the notch 3, the leader feeding device stops, and at the same time,
The cutter device 4 operates to cut the film F in the vicinity of the tape piece T.

FIG. 4 shows a state in which the film F is cut and separated. After the film is cut, the rotating shaft 7 is rotated clockwise. The rotation of the rotation shaft 7 causes the support shaft 9 to rotate.
, And at the same time, the rotation of the rotating shaft 7
Since the power is transmitted to the support shaft 9 via 23, the support shaft 9 rotates.

The rotation of the support shaft 9 causes the cam 24 to push up the movable bar 13, so that the movable bar 13 moves toward the fixed bar 12, and the clamping pad 1 provided on the fixed bar 12 and the movable bar 13
4 and 15 hold the tape piece T from above and below.

On the other hand, the tip of the arm 10 deflected toward the first stopper 31 by the spring 32 due to the revolution of the support shaft 9 moves downward along the first stopper 31, and the arm 10
Falls down on the disk 8 toward the rear side in the rotational direction, and is inclined as shown in FIG.

The angle of inclination of the arm 10 increases as the rotation of the rotating shaft 7 advances, and at the same time, the clamp device 11 supported on the distal end of the arm 10 moves downward. Above arm
When the clamp device 11 lowers below the level of the lower surface of the support base 1 by inclining at a predetermined angle in a state where 10 contacts the first stopper 31, the second stopper 33 provided on the disk 8 comes into contact with the arm 10, The arm 10 rotates together with the disk 8 while being supported by the second stopper 33 (see FIG. 6).

When the rotating shaft 7 is further rotated, the clamp device 11 rotates below the support table 1, so that the tape piece T clamped by the clamp device 11 is pulled down obliquely below the support table 1 and shown in FIG. Thus, it is separated from the reader L.

The rotation shaft 7 further rotates from the above state, and stops after approximately 180 °. At this time, as shown in FIG. 8, the arm 10 is held substantially horizontally below the rotating shaft 7, and the small diameter portion of the cam 24 is in contact with the cam follower 25. twenty one
Moves in a direction away from the fixed bar 12 due to the elasticity of.
Therefore, the holding of the tape piece T is released, and the tape piece T falls downward and is collected in the receiving tray 34 provided below the tape piece T.

After the disposal of the tape piece T as described above, the rotating shaft 7 is rotated by 180 ° in the reverse direction, and before the rotating shaft 7 stops, the tip of the arm 10 comes into contact with the first stopper 31 and stops. When the rotary shaft 7 stands up and stops, as shown in FIG. 4, it is held vertically above the rotary shaft 7.

In the case of the embodiment, the reader L is shown as a sheet-like material,
Although the peeling of the bonded tape piece T has been described as an example,
The sheet is not limited to the reader.

In addition, although the clamp device 11 includes the fixed bar 12 and the movable bar 13 movable toward the fixed bar 12, the clamp device 11 is configured to open and close a pair of open / close claws with a solenoid or the like. Is also good.

When the tape piece T is separated from the leader L, if the leader L moves on the support 1, the tape piece T cannot be separated, so that the pressing member that presses the leader L on the support 1 can be moved up and down freely. It is preferable to provide it.

〔The invention's effect〕

As described above, according to the present invention, the clamp device for holding the tape piece is moved downward from the sheet-like transfer path, and is moved downward from the level of the lower surface of the support base for supporting the sheet-like material. Since the rotation is performed below the support table, the tape pieces adhered to the sheet-like material can be automatically and efficiently peeled off.
