[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, an apparatus for peeling a protective film attached to a printing plate material after exposure, or a support film only after exposure of a photosensitive film attached to a printed circuit board, or a support film. The present invention relates to a device for peeling a cover film attached to the surface of a plate material, such as a device for peeling together the unexposed portion of the photosensitive layer.

[0002]

2. Description of the Related Art Conventionally, as an apparatus for peeling a cover film attached to the surface of a plate material, for example, JP-A-61-103
In Japanese Patent Publication No. 152-152, a double-sided adhesive tape is attached in the width direction at one end of the cover film surface of a plate material to which the cover film is attached, and then the tape is attached to the tape and a winding member having good adhesiveness. An apparatus has been proposed in which the cover film attached to the surface of the plate material is sequentially peeled from one end thereof by winding the cover film.

In Japanese Patent Laid-Open No. 167176/1987, a single-sided adhesive tape is attached in the width direction of one end of the cover film on which the cover film is attached, with the single-sided adhesive tape protruding from the tip of the plate. After that, the protruding portion of the single-sided adhesive tape is bent upward, the tape is attached to the tape and the take-up member with good adhesiveness, and the cover film is taken up by winding the cover film at one end. An apparatus for sequentially peeling from a part has been proposed.

In any of these, an adhesive tape is attached to one end portion of the surface of the cover film attached to the surface of the plate material, and the adhesive tape is attached to the adhesive tape and a winding member having good adhesiveness. Then, by winding the cover film, the cover film attached to the surface of the plate material is sequentially peeled from one end thereof.

Further, the present inventors previously proposed (Japanese Patent Application No. 3-
No. 269026) presses an adhesive roll having pressure-sensitive adhesiveness to a cover film attached to the surface of a plate material, causes the cover film to be attached and temporarily winds the cover film around the adhesive roll, and then the cover film is attached to the adhesive roll. It is characterized by being pushed into a nip roll while being peeled off from the nip roll, the cover film wound around the adhesive roll is housed in a dust box, and the adhesive roll is repeatedly used.

[0006]

However, Japanese Patent Laid-Open No. 61-103152 and Japanese Patent Laid-Open No. 62-1671.
The device proposed in Japanese Patent Publication No. 76 has the following problems. That is, when any of the above-mentioned conventional devices is used, when the cover film attached to the surface of the plate material is peeled from the plate material, a double-sided or single-sided adhesive tape in one end width direction of the cover film attached to the surface of the plate material. Therefore, there is a problem that a large amount of the adhesive tape for peeling, which is at least equal to the widthwise length of the plate, is consumed for each plate and the cover film is costly to peel.

Further, when the peeling pressure-sensitive adhesive tape is attached to the surface of the cover film in the width direction at one end, it is necessary to temporarily stop the transportation of the plate material. Therefore, there is a problem that the peeling operation of the cover film cannot be continuously performed, the time required for the peeling treatment of the cover film becomes long, and the number of peeled cover films per unit time is small.

On the other hand, the present inventors first proposed (Japanese Patent Application No. 3-
No. 269026) is a method in which the above-mentioned drawbacks of the prior art are solved, but the entire width of the cover film adhered to the surface of the plate material is simultaneously peeled by conveying the edge portion of the plate material in parallel with the adhesive roll. The initial peeling of the cover film requires a very large peeling force and the pressing force of the adhesive roll against the cover film needs to be increased. In particular, when the plate material is wide, the adhesion of the cover film to the adhesive roll is not uniform in the width direction of the plate material,
In some cases, tackiness was partially caused, resulting in peeling failure. Further, when the cover film wound around the adhesive roll is peeled off from the adhesive roll, the cover film adheres to the entire outer peripheral surface of the adhesive roll, which requires a very large force. Further, there is a problem that the cover film is broken without being able to endure the excessive pulling force, and the cover film remains on the surface of the adhesive roll, so that the next peeling treatment cannot be performed. Further, since the method of accommodating the peeled cover film in the dust box, the volume of the accommodated cover film becomes large, and it becomes necessary to take out the cover film in the dust box frequently, and There was a problem that it took time to handle.

The present invention has been made in view of the above circumstances, and the cover film can be peeled at low cost without using an adhesive tape for peeling the cover film, and the efficiency of the peeling treatment of the cover film can be improved. It is an object of the present invention to provide a cover film peeling device having high reliability and high reliability of the peeling process.

That is, the invention according to claim 1 carries the plate material, to which the cover film is adhered, into the adhesive roll in a state in which the ridge of the transport tip is inclined with respect to the axis of the adhesive roll,
The cover film is wound around the adhesive roll to separate the cover film from the surface of the plate material.

Further, the invention according to claim 2 is a cover film in which a member having adhesiveness is pressed and adhered to a cover film attached to the surface of a plate material, and the cover film is integrally peeled together with the adhesive member. In the peeling apparatus, the plate material conveying means for conveying the plate material to which the cover film is attached, and the pressure-sensitive adhesive which is arranged in parallel on the conveying surface of the plate material conveying means and is erected vertically. Roll, a cover film wound on the adhesive roll, a take-up means for taking out from the adhesive roll,
A means for conveying the plate material conveying means to the adhesive roll in a state of being inclined with respect to the axis of the adhesive roll.

According to a third aspect of the present invention, the pressure-sensitive adhesive portion provided on the outer periphery of the adhesive roll is formed in a spiral shape having a predetermined width dimension and being substantially equal to the inclination angle of the conveyance leading edge of the plate material. The pressure-sensitive adhesive surface of

According to a fourth aspect of the present invention, the take-up means for taking up and housing the cover film wound around the adhesive roll from the adhesive roll is constituted by a take-up shaft having a drive means. is there.

Further, in the invention described in claim 5, the cover film wound on the pressure-sensitive adhesive roll is taken from the pressure-sensitive adhesive roll, and when the film is wound on the winding shaft, the cover is wound on the pressure-sensitive adhesive roll. The double-sided adhesive material is attached to the surface of the film, the cover film is guided to the winding means, and the film is wound around the winding shaft.

[0015]

According to the invention described in claims 1 and 2, the plate material on which the cover film is adhered is conveyed by the plate material conveying means in a state of being inclined with respect to the adhesive roll by the positioning means, and the adhesive roll is attached to the leading edge portion of the plate material. Press and stick. The cover film attached to the surface of the plate comes into contact with the pressure-sensitive adhesive surface of the adhesive roll, and the edge of the edge of the plate (right or left end)
Then, it is peeled off sequentially in the width direction and wound on an adhesive roll. When the cover film of a predetermined size is wound on the adhesive roll, the pressure on the plate material surface of the adhesive roll is released,
The adhesive roll rises from the plate surface. Further, the cover film on the plate material is peeled to the rear end of the plate material by the take-up force of the take-up means, and the cover film wound around the adhesive roll is entirely transferred to the take-up means. As a result, the adhesive surface of the adhesive roll is exposed, and the cover film of the next plate is peeled off by repeating the above-described operation.

According to the third aspect of the present invention, the spiral adhesive portion of the adhesive roll adheres to the front end portion of the plate material only with a constant width, and the cover film adhered to the surface of the plate material is closer to the edge portion of the front end portion of the plate material. The tape is sequentially attached to the adhesive roll in the width direction and wound up.

According to the fourth aspect of the present invention, the cover film wound on the adhesive roll is taken up by the take-up shaft to be removed from the adhesive roll.

Most of the outer peripheral surface of the adhesive roll 5 is covered with a non-adhesive member, and only the portion that adheres to the leading end portion of the plate material conveyed in an inclined state has a pressure-sensitive adhesive having an appropriate width dimension corresponding to the plate material angle α. The members are arranged in a spiral shape.

As means for constructing this spiral adhesive member, a pressure-sensitive adhesive material is used on the entire outer peripheral surface of the adhesive roll, and a non-adhesive member such as a plastic film is spirally wound so that the adhesive surface of a predetermined width is exposed. There is a method of applying and masking, a method of spirally winding a pressure-sensitive adhesive tape having an appropriate width on a roll made of a non-adhesive member, and the like.

The pressure-sensitive adhesive member 5a is generally based on a polymer base such as polyurethane, natural rubber, polychloroprene, polyisobutylene, polyacrylate rubber, and polyvinyl ether rubber, on which a softening agent (plasticizer) is added. Alternatively, a material to which a tackifier is added is preferably used. When the adhesive strength of these adhesive materials is reduced due to dust, dust or the like attached to the surface after use, the adhesive function is quickly recovered by washing with a solvent such as water or alcohol, and the adhesive material can be easily reused. In any case, the adhesive force of the pressure-sensitive adhesive member 5a used for the adhesive roll 5 is
It is necessary that the adhesive force of the cover film 1b with respect to the plate material main body 1a be stronger, and it is desirable that the cover film 1b attached to the adhesive roll 5 can be mechanically easily detached. Such a pressure sensitive adhesive member 5a
Among the above-mentioned adhesive members, a polyurethane-based adhesive (specifically, an adhesive obtained by the manufacturing method disclosed in Japanese Patent Publication No. 53-31192) is preferable.

A peeling guide roll 7 is provided in parallel with the adhesive roll 5 at a position closer to the carrier 2 on the lower side of the mounting position of the adhesive roll 5.

Further, the shaft 14a is provided with a stopper 14c for controlling the unwinding amount of the double-sided adhesive tape T.

The cover film 1b pulled up by the adhesive roll 5 is wound up with the take-up roll 8 at a position opposite to the nip point between the take-up roll 8 and the take-up shaft 9 on the side better than the mounting position of the adhesive roll 5. Axis 9
There is an inserter 12 for pushing into the nip point.
At the tip of the inserter 12, the cover film 1b is attached.
A film sensor 12a for detecting the presence or absence of is attached.

Incidentally, S1 to S3 in the drawing are plate material sensors for optically detecting the presence or absence of the plate material 1 on the carrying table 2.
Reference numeral 3 is a lamp showing a state (standby state) in which the apparatus is ready to receive the plate material 1.

The operation of this apparatus will be described below in order. Figure 1
As shown in, the state in which the sensors S1 to S3 do not detect the plate material 1 is the standby state of the present apparatus. In this state, the lamp 13 is turned on to display to the operator that the plate material 1 can be supplied. At this time, the rolls 3a, 3b, 4, 8, 9 of the apparatus are stopped, and the adhesive roll 5
Is in a position where it is integrally lowered with the support mechanism 6 and is pressed against the backup roll 4, and when the plate material is conveyed, the spiral adhesive portion of the adhesive roll 5 synchronizes with the tip end portion of the plate material and is rotated and pressed to adhere to the sensor. It is detected in S4 and stopped at the predetermined position. The means for pressing the pressure-sensitive adhesive roll 5 is not limited to the spring material 6a, and a pressure means such as a weight or a pressure cylinder may be used. Inserter 12 is in the retracted position.

As shown in FIG. 2, the plate material 1 is supplied along the carrier table 2 and the positioning members 2a and 2b. At this time, the plate material 1 is supplied by the positioning members 2a and 2b in a state of being inclined by an angle α with respect to the axial direction of the transport nip roll 3a. The inclination angle α of the plate material may be 1 to 45 degrees, but the inclination angle α is preferably 10 degrees or less because the apparatus becomes larger when the inclination angle is increased. Further, the positioning members 2a and 2b are mechanisms that use a solenoid, a pressure cylinder, etc. in a mechanism that moves in and out on the surface of the carrier table so as not to hinder the progress of the plate material when the plate material 1 is transported by the transport nip roll 3a. Further, when the width of the plate material to be processed is always constant, it is appropriate to provide the fixed positioning guide 2c.

As shown in FIG. 3, when the plate material 1 is fed along the carrying table 2 and the positioning members 2a and 2b, and the plate material sensor S1 detects the tip of the plate material 1, the lamp 13 is turned off based on this. Display the start of operation to the operator.

The transport nip rolls 3a and 3b, the backup roll 4, the take-up roll 8 and the take-up shaft 9 are driven, and at the same time, the positioning members 2a and 2b are pulled down below the surface of the transport table. Is conveyed in the direction of the adhesive roll 5.
When the plate material 1 is conveyed and is sandwiched between the adhesive roll 5 and the backup roll 4, the cover film 1b attached to the plate material 1 is attached to the adhesive roll 5 and the backup roll 4.
Since it is rotated and pressed by and, it is sequentially adhered to the adhesive part of the adhesive roll 5 in the plate width direction from the top of the tip ridge, and the cover film 1b is sequentially peeled off, and only the plate body 1a is conveyed to the lower side. To go.

As shown in FIG. 4, after the tip portion of the plate material body 1a is detected by the plate material sensor S2, the cover film 1b having a predetermined length is wound around the adhesive roll 5 and then the adhesive roll 5 is raised. Stop at intermediate position. At this time, the peeling guide roll 7 prevents the plate body 1a from rising so that the plate body 1a does not rise together with the adhesive roll 5.
When the plate material 1 is conveyed in this state, the cover film 1b having a length corresponding to the conveyance distance of the plate material 1 is peeled off and engaged with the peeling guide roll 7. After that, cover film 1
The peeling angle θ of b is regulated by the peeling guide roll 7. At this time, the peeling force of the cover film 1b can be made small by making the peeling angle θ of the cover film 1b large, preferably 180 °, by making the distance between the peeling guide roll 7 and the plate material 1 as small as possible. it can. As a result, it is possible to prevent the plate material body 1a from being lifted or deformed when the cover film 1b is peeled off, and to reduce the driving force of the transport nip rolls 3a and 3b and the take-up roll 8.

As shown in FIG. 5, when the plate material 1 is further conveyed, a predetermined length of peeling processing is performed, and the plate material sensor S3 detects the plate material main body 1a, the adhesive roll 5 rises to the upper limit position and the tape applicator. 14 and the cover film 1b wound on the adhesive roll 5 come into contact with each other, and the stopper 14c of the tape applicator 14 is removed from the unwinding shaft 14a by a driving device (not shown). Next, the inserter 12 advances and moves the cover film 1b in the intermediate portion between the adhesive roll 5 and the peeling guide roll 7 toward the take-up roll 8. At this time, the film sensor 12a provided at the front end of the inserter 12 has the peeled cover film 1b.
When the inserter 12 is detected, the inserter 12 further moves to the take-up nip roll 8 side. If the film sensor 12a does not detect the cover film 1b, it is determined that the peeling of the cover film 1b is defective, the operation of the apparatus is stopped, or the transport nip rolls 3a and 3b and the backup roll 4 are reversed to supply the plate material 1. Perform processing such as discharging to the side.

Cover film 1 with film sensor 12a
When b is detected and the inserter 12 further advances, as shown in FIG.
As shown in, the cover film 1b wound around the adhesive roll 5 is unwound by a length corresponding to the amount of advance of the inserter 12. At this time, the unwinding shaft 1 of the tape applying machine 14
The double-sided adhesive tape T attached to 4a is unwound,
The double-sided adhesive tape T is affixed on the cover film 1b, and the release paper of the double-sided adhesive tape T is taken up by the take-up shaft 1
It is wound up on 4b. Take-up roll 8 and take-up shaft 9
The cover film 1b is pushed into the meshing part of the.
As shown in FIG. 7, the stopper 14 of the tape applying machine 14
c is engaged with the unwinding shaft 14a, the adhesive roll 5 descends to the intermediate position again, and the double-sided adhesive tape T is cut. The inserter 12 retracts, the cover film 1b is nipped by the biasing force of the spring 9a attached to the take-up roll 8 and the take-up shaft 9, and the take-up of the cover film 1b is started. At this time, the cover film 1b is moved to the winding shaft 9 by the double-sided adhesive tape T attached on the cover film 1b and the winding is started, and the cover film 1b adhered to the adhesive roll 5 and the plate material 1 to the cover film 1b. Are sequentially and continuously peeled off and taken up by the winding shaft 9. When the cover film 1b is peeled from the adhesive roll 5, since the cover film 1b is adhered to the adhesive roll 5 from the tip to the spiral adhesive surface with a predetermined width, the partial peeling in the width direction is sequentially performed. Therefore, the driving force of the winding shaft 9 can be reduced. Also,
When the sensor S1 no longer detects the plate material, the positioning member 2
a and 2b project on the transfer surface of the transfer table 2.

Even after the peeling of the cover film 1b from the plate material 1 is completed, as shown in FIG. 8, the operation of the present apparatus is continued, the end of the cover film 1b is taken off, and the cover film 1b is adhered to the adhesive roll 5. The cover film 1b is peeled off. On the other hand, the plate material main body 1a, from which the cover film 1b has been peeled off, passes through the transport nip roll 3b and is then sent to the next step (not shown).

Generally, a protective film attached to a printing plate material, a photosensitive film attached to a printed circuit board or the like has a small thickness and a small rigidity. Moreover, since static electricity is generated and charged during peeling, the cover film 1b after peeling is apt to stick to the device when it comes into contact with the device portion, and its handling is often very difficult. Therefore, as shown in FIG. 8, in this embodiment, the cover film 1 on the outer periphery of the take-up roll 8 is provided.
A scraper 10 is provided on the outer peripheral portion of the take-up roll 8 in order to prevent the winding of b.

As described above, when all the peeled cover films 1b are wound on the winding shaft 9 and all the plate material sensors S1 to S3 no longer detect the plate material main body 1a, the adhesive roll 5 is at the lower limit position. And comes into contact with the backup roller 4 and rotates. After that, when the matching mark provided on the adhesive roll 5 is detected by the sensor S4, each roll driving unit of the apparatus is stopped, the lamp 13 is turned on, and the standby state shown in FIG. 1 is restored.

The tape sticking machine in the present invention is not limited to the sticking machine for the double-sided adhesive tape T as in the above embodiment, and may be, for example, a device for supplying an adhesive or a sticking place. It may be stuck on the winding shaft instead of on the adhesive roll.

Further, the plate material conveying means in the present invention is not limited to the one using the nip roll as in the above-mentioned embodiment, but a belt conveyor may be used, for example. Further, the peeling guide means is not limited to the peeling guide roll 7 as in the embodiment, and a rod-shaped member or a plate material may be used.

[0044]

As is apparent from the above description, according to the inventions of claims 1 and 2, the plate material to which the cover film is adhered is inclined with respect to the conveying direction and is adhered while being conveyed. By bringing the roll into contact with the plate material, the cover film is wrapped around the adhesive roll, peeled off, and taken off, so that the cover film can be repeatedly peeled off using the same adhesive roll. Since it is not necessary to use a tape, the cost required for the peeling process of the cover film can be reduced.
Further, since it is not necessary to temporarily stop the plate material for peeling the cover film unlike the conventional apparatus, the peeling treatment of the cover film can be continuously performed, and the treatment efficiency is remarkably improved. Further, since the adhesive is peeled off sequentially from the edge portion of the plate material in the width direction, the force required for peeling can be reduced, and the reliability of the cover film peeling operation is significantly improved.

According to the third aspect of the invention, the cover film is wound around the adhesive roll and peeled off by bringing the adhesive roll having the adhesive member arranged in a spiral shape into contact with the plate material, and the cover film is removed from the adhesive roll. Since partial peeling in the width direction can be sequentially performed at the time of peeling, the winding force can be reduced and breakage of the film can be eliminated. Therefore, the peeling process of the cover film can be continuously performed without the cover film remaining on the adhesive roll.

According to the invention described in claim 4, since the cover film wound around the adhesive roll is wound and accommodated in the winding shaft having the driving means, the cover film becomes small in volume and a large amount of plate material The peeling treatment can be continuously performed.

According to the fifth aspect of the present invention, since the double-sided adhesive material is attached to the cover film wound around the adhesive roll and is transferred to the winding shaft and accommodated for winding, the winding operation of the cover film is ensured. Therefore, the reliability of the cover film accommodating operation is improved.
