Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a plate material, for example, an apparatus for peeling off a cover film provided in close contact with the surface of the plate material to protect the surface of the plate material, or , a device for adhering a photosensitive film consisting of a support film layer and a photosensitive layer to the required surface of a printed circuit board, and peeling off the support film alone or the support film and the uncured portion of the photosensitive layer together after exposure of the film, etc. The present invention relates to a cover sheet peeling method and apparatus.

(Prior art) As a method for peeling off a cover sheet that is tightly adhered to the surface of a printing plate, etc., for example, Japanese Patent Application Laid-Open No. 51-9451 discloses a method in which a plate with a film to be peeled adhered to a desired surface is fed in one direction. A film peeling method has been proposed in which a cover film is integrally peeled off together with the adhesive tape by utilizing the adhesiveness of an adhesive tape that is placed so that the adhesive surface faces the surface of the film to be peeled during the movement, and the specific details thereof have been proposed. The peeling method can be understood from Figures 1, 2, and 3.

(Problems to be Solved by the Invention) When peeling off a cover film that is closely adhered to the surface of a plate using the above-mentioned conventional technique,
In general, the cover film near the edges of the board is easily scratched during cutting, packaging, transportation, etc., and if this scratch is between the rows of single-sided adhesive tape, especially at the end where it is to be peeled off first, it may peel off. In this case, the cover film is torn from the scratched area and a portion remains on the board, making it impossible to completely remove the cover film.

Moreover, it is necessary to crimp multiple lines of single-sided tape with the adhesive side facing the surface of the film to be peeled over the entire length of the film to be peeled, from the advancing end to the rear end on the opposite side. Even if the rows are made into two rows as shown in FIG. 3, the amount of tape used will not be small and will go against the goal of resource conservation.

In addition, after the adhesive tape has moved a predetermined amount along with the plate, the adhesive tape is pulled in the opposite direction to the traveling direction of the plate to peel the tip of the film to be peeled from the plate, and then the adhesive tape is pulled out and the film to be peeled is removed. Since it peels off from the film, a swinging mechanism or the like is required, which is disadvantageous in terms of simplifying the device.

Furthermore, next, the structure of the cover sheet peeling section and the plate material take-up section will be explained.

Next to the above-mentioned plate material conveyance means and double-sided adhesive tape pasting section, paper is surface driven in the direction of conveyance of the plate material by a rotating body 24 having an elastic body wound around the surface of a sponge or the like via a guide plate 26. A cover is provided with a winding body 23 such as a tube, which rotates while directly pressing the outer surface of the tape of the transported board material, winds up the tape by adhesive, and peels off the cover sheet adhered to the tape from the board material. It has a sheet peeling part. Furthermore, it has a plate material take-off section such as a pair of nip rolls 25, 25 from which the plate material from which the cover sheet has been peeled off by the cover sheet peeling section is taken off. In addition, 27 is a main body frame, and a board material conveyance part, a double-sided adhesive tape pasting part, a cover sheet peeling part, and a board material take-off part are all attached to this frame main body 27.

{effect} Next, the operation of the above-described device will be explained.

In FIG. 1, a plate material 28 having a desired length and width whose surface is covered with a cover sheet is lifted upward by a set roll 6 by a magnet 7, and then
With the claw-like stopper 3 raised upward by the magnet 5 via the stopper fulcrum shaft 3a,
It is conveyed by a conveyor 1. Here, plate material 2
8 is placed on the conveyor 1 so that the predetermined right side of the plate 28 in the traveling direction matches the right side of the guide plate 2 so that the end of the double-sided adhesive tape 29 that will be attached to the plate 28 later can be cut. placed in position. The tip of the board 28 is adjusted in the TD direction by the conveyor 1 and the claw-shaped stopper 3, which continue to move while being conveyed by the conveyor 1 and whose progress is temporarily blocked by the claw-shaped stopper 3. Simultaneous sensing completes this trimming operation.

Conveyor 1 stops and magnet 7 turns off
Then, the set roll 6 falls and grips and fixes the plate material 28 between it and the conveyor 1, while the claw-like stopper 3 is lowered by the spring 4, completing the positioning of the tip of the plate material 28 and the fixing operation of the plate material. do.

Next, the operation of applying the double-sided adhesive tape begins.

The attachment part of the double-sided adhesive tape 29 has been moved in advance to the standby position on the side of the inclined guide plate 20, and due to the contact between the plate protruding part 16a and the inclined guide plate 20, the plate protruding part 16c is removed from the setting plate spring. When the plate 15 is removed, the plate protrusion 16a side is downward with the fulcrum shaft 15a as the fulcrum. The guide roll 12 is on the surface of the guide plate 2.

In this state, following the above-mentioned operation of positioning and fixing the tip of the plate material 28, the pasting part of the double-sided adhesive tape 29 is moved to the inclined guide plate 21 side of the guide bar 19.
will be guided to. The guide roll 12 is the guide plate 2
Since the pasting roll 11 travels in the TD direction on the surface of the plate material 28 (see FIG. 3) and comes into contact with the plate material 28, the small-diameter guide roll 12 is slightly raised from the surface of the plate material 28. In this state, the preset double-sided tape 29 is attached to the plate material 28.
The guide roll 12 presses the release paper 30 onto the entire end surface of the upper cover sheet in the direction of travel, while the release paper 30 is wound around the release paper take-up roll 10.

The moment the slide plate 14 leaves the end of the plate 28, the cutter 13 side of the plate 15 falls, using the fulcrum shaft 15a as a fulcrum, and the double-sided adhesive tape 2
The pasting terminal 9 is cut by a cutter 13. Next, the guide roll 12 rotates the inclined guide plate 2
1. This fall stops when it reaches the top surface. When the guide roll 12 further ascends on the inclined surface of the inclined guide plate 21, the plate protrusion 16c side rises about the fulcrum shaft 15a, and the plate protrusion 16c is set on the setting leaf spring 18.

Furthermore, when the plate protrusion 16b comes into contact with the limit switch 21a, the double-sided adhesive tape application section
The traveling direction is reversed, and the guide bar 19 is guided in the opposite direction to proceed toward the inclined guide plate 20,
The upper surface of the plate protrusion 16a contacts the lower inclined surface of the inclined guide plate 20, and the plate 15
The plate protrusion 16c side is lowered with a as a fulcrum, and the plate protrusion 16c is attached to the setting plate spring 18.
is removed, the guide roll 12 hits the upper surface of the guide plate 2, and the plate A15 is prevented from falling.

Furthermore, when the tip of the plate protrusion 16a contacts the limit switch 20a, the double-sided adhesive tape application section stops advancing in the reverse direction and returns to the original standby position, completing the operation of the double-sided adhesive tape application section and starting the next step. The final operation of the cover sheet peeling and winding section begins.

Simultaneously with the completion of the operation of the application part of the double-sided adhesive tape 29, the conveyor belt 1, the sponge roll 24, and the pair of take-up rolls 25 start rotating, and the double-sided adhesive tape 29 is attached to the plate material 28 pasted on the cover sheet in the TD direction of the tip end. transportation will begin. The double-sided adhesive tape at the tip of the cover sheet is connected to the winding paper tube 23.
The winding paper tube 23, which is adhered to the cover sheet and is conveyed to the surface by a sponge roll, sequentially peels off all the ends of the cover sheet in the direction of travel from the tip to the opposite side in the direction of travel, and winds it up. I'll follow you.

When the end of the plate material 28 passes through the part of the claw-shaped stopper 3, the limit switch 8 is actuated to activate the magnet 5, and the claw-shaped stopper 3 is moved upward via the stopper fulcrum shaft 3a and returned to its original position. Similarly, the set roller 6 is also raised by operating the magnet 7 and returned to its original position.

A series of operations are completed above, and the control device sequentially repeats these operations to continuously peel and wind up the cover sheet of the plate material.

In the above embodiment, the tape application roll 1
1 shows a roller that rotates while pressing the cover sheet, but the roller is not limited to this; it slides while pressing to apply a double-sided adhesive tape to the one end of the cover sheet in the width direction. It may also be a slide plate to which tape is attached.

In addition, the cutter attached to the tape pasting part,
In this mode, the blade is fixed to the device main body side with the blade facing upward at the part to be cut off at the tape pasting terminal, and the tape side is dropped onto the blade, and the tape is cut by pressing the tape against the blade. Good too.

{Effects of the Invention} Since the present invention has the above configuration, it has the following effects.

Double-sided adhesive tape is continuously pasted on all edges of the cover sheet in the direction of travel, and while pressing all edges of this cover sheet with a rotating body wider than the cover sheet through the double-sided adhesive tape. Because it is rolled up in one piece, even if the cover sheet is scratched or torn at the edge in the direction of travel during the cutting, packaging, or transportation process, the cover sheet may be torn from this area, or some sheets may become stuck to the board. The disadvantage of remaining on the body is eliminated.

Since the cover sheet winding drive roll uses an elastic body such as a soft elastic sponge roll, even if there is a winding step on the winding paper tube due to the difference in the width of the cover sheet, the nip pressure and the elastic force of the elastic body will prevent the winding from occurring. The double-sided adhesive tape portion of the cover sheet is sufficiently adhered to the winding paper tube side, and the cover sheet can be rolled up while being sequentially peeled off.

Since the guide roll 12 is attached to the double-sided tape pasting part, the double-sided adhesive tape can be pasted to any board width, and the pasted end can be cut by a cutter in a natural fall manner. This eliminates the need for complicated equipment that detects the position using an optical sensor and operates the cutter.

In addition, since the present invention uses a method in which the cover sheet is peeled off by pasting double-sided adhesive tape only on the peeling part at the tip of the plate material, the cover sheet peeling part does not have a complicated mechanism such as a sliding mechanism, and is simple. At the same time, the amount of tape consumed is lower than the method in which multiple adhesive tapes are attached and peeled off in the MD direction of the plate material.
