Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adsorption pad for adhering a tape when an original film is attached by a tape onto a mount in photoengraving, and a film attaching apparatus using the adsorption pad.

[0002]

2. Description of the Related Art In photolithography, each original film (negative film) color-separated from an original is pasted on a mount (also referred to as a base film) for each color with a tape, an adhesive, etc. Print on a positive film (photochromic film) with a printer,
The original film is made by reversing the positive.

At this time, for the alignment between the color plates, see the original film (usually a magenta plate) made first,
In accordance with this, the workers have attached color separation versions of other colors on the respective base films.

As described above, conventionally, the operator performs the alignment and pastes while checking each plate with the naked eye, so that the operator is highly tired, the work efficiency is low, and the alignment accuracy is high. It was difficult to make a high quality original film due to individual differences.

In order to deal with this, the original film is automatically taken out from the tray, the original film is placed on the table on which the mount is placed, the original film is placed, and the tape is attached by the tape attaching unit provided in the take-out means. A film sticking device for sticking has been developed.

FIG. 5 is a schematic configuration diagram of such a film sticking device. This device is roughly divided into a tray unit 1 for storing a mount and an original film, front and rear (X axis) and left and right (Y
The table 2 is movable in the (axis) direction and is rotatable in the direction θ, and the Z table 3 is movable in the vertical direction.
It consists of

Of these, the tray portion 1 is provided on the front surface of the main body, and is supported by support frames 4a and 4b provided on both side surfaces so as to be horizontally movable back and forth, and is inserted and removed between the θ table 2 and the Z table 3. It is free.

Specifically, the tray unit 1 includes, for example, first and second film trays 5 and 6 for storing the original film, first and second mount trays 7 and 8 for storing the mount, and the original film. Plate discharge tray 9 for storing the backing sheet after pasting
And have.

With such a construction, first, the mount is set on each mount tray 7 and 8, and the original film is set on each film tray 5 and 6.

When the operation is started in this state, the Z table 3 is lowered to the mount receiving position, and, for example, the mount tray 7
Enters between the Z table 3 and the θ table 2.

When the mount tray 7 enters, the vacuum of the suction pad provided on the Z table 3 operates, and the mount is sucked onto the Z table 3. And the mount tray 7
Moves out and returns to the original position, and the Z table 3 is lowered to a position where the mount is transferred from the Z table 3 to the θ table 2 along with it.

Next, the Z table 3 descends to the lowest point and holds the mount on the θ table 2. After that, the Z table 3 moves up to the film receiving position, and the mount is placed on the mount tray 7
And is placed at a predetermined position on the θ table 2.

Next, the film tray 6 enters between the θ table 2 and the Z table 3, and the original film is taken out from the film tray 6 as in the case of the mount, and the film tray 6 is placed on the Z table 3. Adsorbed.

After that, the Z table 3 descends to the positioning position, the film is registered, and descends to the lowest point. Then, the original film is transferred from the Z table 3 to the mount on the θ table 2, and the original film is held down on the mount on the θ table 3.

Thereafter, the tape is attached to the mount and the original film by the tape attaching head incorporated in the Z table 3.

Here, the operation of attaching the tape will be described.

As shown in FIG. 6, above the mount 10 and the original film 11, twelve tape-adsorbing pads 12 are installed in an array of, for example, 3 × 4 rows. In these suction pads 12, the suction surface (lower surface) of the tape is formed smooth.

Of these, the tape sticking suction pads 12 in the first and second rows are always used, but either the tape sticking suction pads 12 in the third and fourth rows is selectively used depending on the sizes of the mount 10 and the original film 11. Used for. A tape supply unit 13 is provided for each row.

In the initial state, the shuttle 14 is at the initial position on the side of the tape holder 15 as shown in FIG.
6 is closed to sandwich the tip of the tape protruding from the roller pair 17. At this time, the claw 18 is open and the tape is not pinched.

Next, as shown in FIG.
Moves toward the suction pad 12, and the claw 18 moves the roller pair 17
When crossing over, shuttle 14 stops moving (cutting position),
The claws 18 close and pinch the tape. After that, the cutter 19 descends and the tape is cut between the claw 18 and the roller pair 17.

While the tape piece 15 is sandwiched by the claws 16 and 18, the shuttle 14 is further moved to the suction pad 12 side as shown in FIG. At this time, suction pad 1
2 is located above so as not to prevent the passage of the claws 16 and 18. When the shuttle 14 moves to a position directly below the adsorption pad 12, the shuttle 14 stops and the adsorption pad 12
Goes down.

A vacuum mechanism for sucking the tape piece 15 is built in the lower surface of the suction pad 12, and when the suction pad 12 descends, the claws 16 and 18 are opened, and the tape piece 15 moves to the suction pad 12. Adsorbed on the bottom surface. Then, the suction pad 12 is further lowered, and the tape piece 15 is attached to the mount and the original film.

After this, the suction pad 12 rises and the shuttle 14 returns to its original position. Then, the mount 10 after the original film 11 is stuck is adsorbed to the Z table 3, and the plate discharge tray 9 is inserted between the Z and θ tables 3 and 2, and the mount 10 is stored in the plate discharge tray 9 and collected.

[0024]

As described above, the mount 10 is
The original film 11 is stuck on the top, but this is because the tape piece 15 is not completely and smoothly adhered when the pasted board 10 and the original film 11 are adhered to the printing plate and exposed. This is because the incompletely attached portion of the tape causes trouble such as blurring.

However, since the suction surface of the suction pad 12 is formed to be smooth, if there is a slight gap between the suction pad 12 and the tape piece 15 when the tape piece 15 is sucked, the circumference of this gap is reduced. External air may flow in from.

Therefore, air flows into the tape piece 15 and expands, and the tape piece 15 is adsorbed to the adsorption pad 12 in a distorted state instead of being smooth. Further, the tape piece 15 often fails because it cannot be sucked, and the suction itself takes a long time.

In order to prevent such a situation, the tape piece 15 conveyed by the carriage 14 and the suction pad 1
The positional relationship with 2 must be adjusted very precisely. Further, in order to prevent the adjustment deviation due to the repeated film sticking, the readjustment is required periodically, which puts a great burden on the worker.

Further, since the suction surface of the suction pad 12 is smooth, the suction force is weak and the tape piece 1 is in the middle of suction.
5 may fall. Therefore, if a simple suction cup is used instead of the suction pad 12 having a smooth surface, the tape piece 1
5 cannot be adsorbed in a smooth state, and if the tape piece 15 is stuck in this state, that portion will be blurred after contact exposure as described above.

Therefore, an object of the present invention is to provide a suction pad capable of sucking and sticking a tape in a smooth state.

It is another object of the present invention to provide a film sticking device that can stick each film by using a suction pad that can stick and stick a tape in a smooth state.

[0031]

According to a first aspect of the present invention, there is provided a suction pad main body in which a suction surface having a plurality of suction ports is formed smoothly and a concave storage portion is formed on the suction surface.
A suction pad that is intended to achieve the above object by including a suction cup housed in a storage portion and having a smooth portion arranged on the same plane as the suction surface.

According to the second aspect of the present invention, the suction cup has a tongue portion projecting from the suction surface around the smooth portion arranged on the same plane as the suction surface of the suction pad body.

According to the third aspect of the present invention, the second film is superposed on the first film, and the tape for sticking is stuck to the step portion formed by the first and second films. In the device, the suction surface having a plurality of suction ports is formed to be smooth, a concave storage portion is formed on the suction surface, and a suction cup having the smooth portion arranged on the same plane as the suction surface is arranged in the storage portion. The suction pad, a vertical movement mechanism for moving the suction pad up and down with respect to the stepped portion formed by the first and second films, a suction operation of the suction pad to suck the tape, and a suction pad A film sticking apparatus, which is provided with air control means for causing a suction pad to perform an air jet operation when brought into contact with the first and second films, and which is intended to achieve the above object.

[0034]

According to the present invention, since the suction surface of the suction pad main body is formed smooth and the smooth portion of the suction cup housed in the storage portion is arranged on the same plane as the suction surface, the tape is in a smooth state. It can be adsorbed by.

According to the present invention, since the tongue portion is formed around the smooth portion of the suction cup, the tongue portion comes into contact with the tape, and the smooth portion of the suction cup is isolated from the surroundings. The tape can be sucked quickly without flowing in.

According to the third aspect, the suction pad is moved up and down with respect to the step portion formed by the first and second films by the vertical movement mechanism, and at this time, the suction pad is sucked by the air control means. Then, the tape is sucked in a smooth state, and when the suction pad is brought into contact with the first and second films, air is ejected from the suction pad. Thus, the tape can be quickly sucked without air flowing in from the surroundings, and in this state, the tape can be attached to the step portion of the first and second films.

At this time, due to the action of the sponge 21 sandwiched between the support 20 and the suction pad 22, the suction pad body 22 flexibly tilts in accordance with the step between the mount 10 and the original film 11, and the tape piece 15 as a whole. Is uniformly pressed against the stepped portions of the films 10 and 11.

Thereafter, the suction pad main body 22 rises and the shuttle 14 returns to the original position. When the shuttle 14 returns, the pawls 16 and 18 pass through the concave portion of the suction pad body 22 as shown in FIG. 4 (c).

Then, the mount 10 after the original film 11 is stuck is adsorbed on the Z table 3, and the plate discharge tray 9 is inserted between the Z and θ tables 3 and 2 to store the mount 10 in the plate discharge tray 9. to recover.

As described above, in the above-described embodiment, the suction surface 23 of the suction pad main body 22 is formed to be smooth, and the smooth portions 27a and 28a of the suction cups 27 and 28 stored in the storage portions 24 and 25 are suctioned. Since the tape piece 15 is arranged on the same plane as the surface 23, the tape piece 15 can be sucked in a smooth state.

Further, the smooth portions 27a of the suction cups 27, 28,
Since the tongue portions 27b and 28b are formed around the 28a, the tongue portions 27b and 28b come into contact with the tape piece 15 and the smooth portions 27a and 28a of the suction cups 27 and 28 are isolated from the surroundings. The tape piece 15 can be swiftly sucked without air flowing in from the inside.

Therefore, this suction pad main body is applied to a film sticking device, and is vertically moved by the vertical movement mechanism 31 with respect to the step portion formed by the mount 10 and the original film 11, and at this time, by the suction jet device 30. The suction pad main body 22 is suctioned to suck the tape piece 15 in a smooth state, and when the suction pad main body 22 is brought into contact with the mount 10 and the original film 11, air is blown from the suction pad main body 22, so It is possible to quickly suck the tape piece 15 without inflowing air from it, and in this state, the tape piece 15 can be attached to the stepped portion of the mount 10 and the original film 11. Even if there is a gap between the suction pad body 22 and the tape piece 15 when sucking 15, the tongue portions 27b and 28b prevent The tape piece 15 can be quickly adsorbed, the tape piece 15 can be adsorbed in a smooth state, and the tape piece 15 can be surely adsorbed without failure, and the tape adsorption time can be shortened.

As a result, when the backing sheet 10 and the original film 11 which are bonded together are brought into close contact with the printing plate and exposed,
Since the tape piece 15 is completely and smoothly attached, trouble such as blurring does not occur due to the tape attachment portion.

Further, since the suction surface of the suction pad 12 is formed smooth and the suction cups 27 and 28 are provided on both sides, the suction force can be increased, and the tape piece 15 drops during the suction. There is no such thing.

When the suction pad main body 22 is pressed against the step portion of the mount 10 and the original film 11, the action of the sponge 21 causes the suction pad main body 22 to move.
And the original film 11 are flexibly tilted according to the stepped portion, and the entire tape piece 15 is evenly formed on each film 10, 1.
