Abstract

PROBLEM TO BE SOLVED: To surely stick original film to plate material so that the film may be easily peeled therefrom. SOLUTION: A pressing roller 84 moves while pressing an adhesive tape 38 stuck to cover over the slot 34 of a negative bar 16. The roller 84 is a crown roller whose outer periphery part is formed of an elastic body. When the roller 84 moves on the slot, its outer periphery part is elastically deformed to press the adhesive tape into the slot. Thus, the adhesive surface of the adhesive tape pressed into the slot is stuck to the negative film, which is surely stuck to the negative bar. Since the slots are made at specified intervals in the longitudinal direction of the negative bar, the negative film is easily peeled from the negative bar.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an original film attaching method and an original attaching device for attaching an original film to a belt-like plate member.

[0002]

2. Description of the Related Art In newspaper printing or the like, a P (photosensitive layer) having a photosensitive layer formed on the surface of a thin plate (eg, about 0.3 mm) of aluminum or the like is used.
A photosensitive lithographic printing plate called an S plate or the like (hereinafter, referred to as a “printing plate”) is used.

[0003] In such a printing plate, in addition to a 2L1W size (hereinafter, referred to as a normal size) in which images of one newspaper page can be vertically arranged and printed, images of one newspaper page can be vertically and horizontally printed. In some cases, a 2L2W size (hereinafter, referred to as a large plate size) is used, and a printing plate printing apparatus capable of processing a printing plate of any size has been proposed.

When exposing a large-sized printing plate,
A two-page spread original film or a one-page newspaper original film is used.

On the other hand, when printing an image recorded on an original film onto a printing plate, it is necessary to accurately position the original film with respect to the printing plate. For this purpose, in the plate printing apparatus, an original film is attached to a predetermined position of a positioning plate, and the plate is positioned with respect to the printing plate, thereby positioning the original film on the printing plate. Things have been suggested.

[0006] By using such a plate material, it is possible to accurately position both a one-page newspaper original film and a two-page spread newspaper original film on a printing plate.

Incidentally, it is preferable to repeatedly use the plate material used for positioning the original film. That is, it is preferable that the original film is attached to the plate material inside the plate material printing apparatus, and when the image printing is completed, the plate material is peeled off from the original film and the next original film is attached.

For this reason, there is a method in which openings are formed at predetermined intervals in the plate material, and an adhesive tape is attached to the plate material so as to cover the openings, and the adhesive tape is attached to the original film in the opening. . That is, since the original film is attached to the adhesive tape at a predetermined interval, the original film can be easily peeled off from the adhesive tape.

However, the problem that the original film is peeled off during the process easily occurs due to the easier the original film is peeled.

On the other hand, when peeling the original film from the plate, there is a method of inserting a peeling blade between the original film and the plate from one end in the longitudinal direction of the plate, and moving this blade in the longitudinal direction of the plate.

However, when two original films are arranged side by side and pasted on a plate, even if a peeling blade enters between one original film and the plate, a peeling blade is inserted between the plate and the next original film. In some cases, the original film remains stuck to the plate material without entering.

[0012]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned facts. In particular, when two original films are arranged side by side and attached to a plate, the original film can be easily and reliably removed from the plate. An object of the present invention is to propose a method of attaching a detachable original film. Another object of the present invention is to propose an original film sticking apparatus that can securely attach an original film to a plate material when the original film is easily peeled from the plate material.

[0013]

The invention according to claim 1 is
A method of attaching a document film in which a thin band-shaped plate material is opposed to a non-image area on a peripheral edge of the document film, and the original film is attached to the plate material with an adhesive tape, and the original film is stretched along a longitudinal direction of the plate material. When arranging and pasting on the plate material, by arranging the original film on one side set in advance so as to be on the plate material side, an overlap is provided on a peripheral portion of the adjacent original films. .

According to the present invention, when two original films are arranged, an overlapping portion is formed on the original film. At this time, the one side original film set in advance is set to the plate material side at the overlapping portion.

Thus, when the original film on one side is peeled off from the plate, the end of the original film on the other side is turned up, so that the original film on the other side can be easily peeled off from the turned-up portion.

According to a second aspect of the present invention, openings are formed in the plate at predetermined intervals along a longitudinal direction, and an adhesive tape is attached to one surface to cover each of the openings. The opening is provided in the plate material so that the overlapped portion of the original film is located between the openings when the document film is in the position.

According to the present invention, by overlapping the two original films between the openings,
Attach the original film to the adhesive tape so that it does not overlap.

This facilitates peeling of the overlapped portion of the original film and prevents the other original film, which should be turned up when the one original film is peeled off, from sticking to the adhesive tape. Thus, the two original films can be reliably peeled off from the plate material.

According to a third aspect of the present invention, openings are formed at predetermined intervals along a longitudinal direction in a thin band shape, and an adhesive tape is attached to one surface to cover each of the openings. What is claimed is: 1. A document film sticking apparatus for sticking a document film on a plate material by said adhesive tape, wherein said positioning means is for positioning said plate material with said opening portion facing a predetermined area of said document film, and formed by an elastic body. A pressing roller gradually widened from each of both ends in the axial direction toward the intermediate portion, and a moving means for rotating and moving the pressing roller along the longitudinal direction of the plate while opposing the pressing roller to the opening of the plate. Pressing means for pressing the pressing roller moved by the moving means toward the original film facing the opening.

According to the present invention, the pressing roller is moved on the adhesive tape attached to the opening of the plate.
At this time, the pressing means presses the pressing roller toward the original film, and the intermediate portion of the pressing roller is swelled and is formed of an elastic body, so that the pressing roller is elastically deformed when facing the opening. Into the opening and press the adhesive tape firmly against the original film.

Thus, since the adhesive tape is securely attached to the original film, the original film is securely attached to the plate material.

When the widthwise ends of the two negative films N are overlapped, the two negative films N
When mounting the negative film N on a tray (not shown) in a temporary position, the end portions in the width direction are overlapped, and two negative films N are integrally stuck from this tray as they are on the stage 4.
2 may be conveyed.

The two negative films N are overlapped with each other when the negative film N is peeled off from the negative bar 16 so that the negative film N to be peeled first is on the upper side. For example, when the negative film N on the right side of the paper of FIG. 3 is peeled off first, the negative film N is set to the upper side.

As a result, as shown in FIG. 6, a peeling blade 98 is inserted between the upper negative film N and the negative bar 16, and this blade 98 is moved along the longitudinal direction of the negative bar 16 to the lower negative film N. When the blade 98 reaches the overlapping portion of the negative film N when moved to the film N side, the negative film N peeled off by the blade 98
Is turned up, and a gap into which the blade 98 enters between the lower negative film N and the negative bar 16 can be generated.

As shown in FIGS. 3 and 4, the negative film N positioned on the attaching stage 42 is attached to the negative bar 16.

The negative bar 16 is formed in a thin and long band shape by steel. The length of the negative bar 16 in the longitudinal direction is the length that both ends in the longitudinal direction project out of the negative film N by a predetermined amount when the two negative films N are arranged in a direction (width direction) orthogonal to the vertical direction. Has become.

At both ends of the negative bar 16 in the longitudinal direction,
A pair of positioning pin holes 32 are formed at predetermined positions, and the pins inserted into the pin holes 32 enable the positioning of the negative bar 16.

At one end of the negative bar 16 in the width direction, a number of long holes 34 are formed as openings along the longitudinal direction. The longitudinal direction of the long hole 34 is formed along the longitudinal direction of the negative bar 16. These slots 34
When the negative bar 16 faces the negative film N, all the long holes 34 correspond to the negative film N. Further, the long hole 34 is formed so as to be separated from the overlapping portion of the two negative films N.

An adhesive tape 38 is attached to the negative bar 16 so as to cover all the slots 34. The negative film N is stuck to the negative bar 16 by sticking the adhesive tape 38.

On the other hand, the attaching section 14 is provided with an attaching / detaching device 44 for the negative bar 16 on the ground side of the attaching stage 42. The attachment / detachment device 44 includes the attaching stage 42
An air cylinder 48 and a pair of guide rods 50 are arranged on a base plate 46 attached to the end of the air cylinder 48.

The air cylinder 48 is attached to the lower surface of the center of the base plate 46, and the drive rod 48A is directed upward. Further, the guide rod 50 has an axis arranged in parallel with the drive rod 48A of the air cylinder 48,
It is movably inserted in bearings 52 provided at both ends of the base plate 46 along the axial direction.

An elevating plate 54 is arranged above the base plate 46. The tip of the drive rod 48A of the air cylinder 48 and the tip of the guide rod 50 are connected to the lifting plate 54, respectively. Thus, when the drive rod 48A of the air cylinder 48 is extended, the elevating plate 54 rises horizontally. Further, as shown in FIG. 4, the lifting plate 54 is moved downward so that the upper surface is substantially the same height as the upper surface of the attaching stage 42.

As shown in FIG. 3, insertion pins 56 corresponding to the pin holes 32 of the negative bar 16 are arranged at both ends of the elevating plate 54 (only one is shown in FIG. 3). The insertion pin 56 is inserted into a bearing 60 attached to the lower side of the elevating plate 54 via a bracket 58, and is moved upward by an elevating means such as an air cylinder (not shown), so that It is designed to protrude.

The elevating plate 54 receives the negative bar 16 in a state in which the insertion pin 56 is moved upward and the insertion pin 56 is projected upward. At this time, the insertion pin 56 is inserted into the pin hole 32 of the negative bar 16. It is designed to penetrate.
At this time, the long hole 34 of the negative bar 16 projects from the lifting plate 54 to the sticking stage 42 side.

On the other hand, the lifting plate 54 is provided with a plurality of magnets 62. These magnets 62 are electromagnets, and the negative bar 1 placed on the lifting plate 54
6 are arranged at predetermined intervals along the longitudinal direction.

Thus, when the magnet 62 is turned on when the negative bar 16 is placed on the lifting plate 54, the negative bar 16 is attracted to the magnet 62 and is held on the lifting plate 54. In this state, by lowering the elevating plate 54 to a predetermined position, the negative bar 16 is positioned with respect to the attaching stage 42. By turning off the magnet 62, the suction holding of the negative bar 16 is released, and the negative bar 16 can be taken out from the elevating plate 54.

As shown in FIG. 3 and FIG.
The negative bar 16 attracted to the magnet 62 by the downward movement of the magnet 4 comes into contact with the non-image area at the ground-side end of the negative film N positioned on the attaching stage 42. Thereby, each long hole 54 of the negative bar 16 faces the negative film N.

On the other hand, the pasting stage 42 is provided with a pasting device 40 at one end side in the width direction of the negative film N.

As shown in FIG. 4, the attachment section 14 is provided with a support frame 64 having a substantially L-shaped cross section along the width direction of the negative film N. A guide rail 66 is attached to the surface of the support frame 64 on the side of the attachment stage 42, and a rodless cylinder 68 is attached to the opposite side of the attachment stage 42. One end of a base 70 is connected to the drive block 68A of the rodless cylinder 68, and a substantially L-shaped bracket 72 attached to the base 70 is movably engaged with the guide rail 66. Have been.

As a result, the drive block 68A of the rodless cylinder 68 moves along the longitudinal direction of the negative bar 16 in the width direction of the negative film N, whereby the base 70 is guided by the guide rail 66 and the negative bar 1 is moved.
6 along the longitudinal direction.

One end of the connecting member 74 is mounted on the base 70. A supporting leg 78 provided with a roller 76 is connected to the other end of the connecting member 74. In addition, the attaching table 42 is provided with a small table 80 extending outward in the width direction at the end of the negative film on the top side. The roller 76 moves on the small table 80 and on the attaching stage 42.

A small table 82 extends outward in the width direction at an end of the pasting stage 42 on the ground side. On the small table 82, a pressing roller 84 is disposed so as to face the long hole 34 of the negative bar 16. The pressing roller 84 has a bracket 88 at one end of a shaft 86.
And is pivotally supported.

The upper end of the bracket 88 has a rod 9
0 is projected, and the upper end of the rod 90 is
0 and is connected to the connecting member 74. Also,
A coil spring 92 is disposed as a pressing means between the bracket 70 and the bracket 88, and the pressing roller 84 is urged downward together with the bracket 88 by the coil spring 92.

Thus, when the rodless cylinder 68 is driven, each of the roller 76 and the pressing roller 84 together with the bracket 70 and the connecting member 74 is moved to the small table 8.
The top and bottom ends of the pasting stage 42 are moved from above 0 and 82 along the width direction. At this time, if the negative bar 16 is held at a predetermined position on the sticking sheet 42 by the attaching / detaching device 44, the pressing roller 84 moves along the long hole 34 of the negative bar 16 in the width direction of the negative film N. It is supposed to.

The outer periphery of the pressing roller 84 is formed of an elastic material such as rubber. Further, as shown in FIG. 5, the pressing roller 84 is a crown roller in which an intermediate portion along the axial direction is widened. Accordingly, when the pressing roller 84 moves on the negative bar 16 while being pressed downward by the urging force of the coil spring 92, the outer peripheral portion of the pressing roller 84 is elastically deformed so as to close the slot 34.

As a result, the adhesive tape 38 applied so as to cover the long hole 34 is pushed into the long hole 34 and further pressed toward the negative film N. Therefore, in the long hole 34, the negative film N and the adhesive tape 3
The adhesive surface of No. 8 adheres, and the adhesive tape 38
Sticks.

On the small table 82, a pair of substantially mountain-shaped guides 94 are arranged. Each guide 94
Is opposed to the shaft 86 of the pressing roller 84 moving on the small table 82. Accordingly, when the pressing roller 84 is moved from above the attaching stage 42 onto the small table 82 by driving the rodless cylinder 68,
The shaft 86 goes up along the inclination of the guide 94,
A shaft 86 extends between the pair of guides. Thus, on the small table 82, the pressing roller 84 is separated from the surface of the small table 82, and the pressing roller 84 is constantly urged downward, thereby preventing deformation.

When the positioning of the negative film N and the holding of the negative bar 16 by the attaching / detaching device 44 are completed, the pressing roller 84 of the attaching device 40 is in the retracting position. 4
2. Rotate upward.

The bracket 70 is provided with a shock absorber (not shown). When the shock absorber moves along the width direction of the negative film N, the shock absorber comes into contact with a stopper (not shown), so that the pressing roller 84 is provided. Is determined.

The operation of this embodiment will be described below.
When the two negative films N are placed and positioned on the attaching stage 42 of the attaching section 14, the printing plate printing apparatus 10 raises the elevating plate 54 of the attaching / detaching apparatus 44,
The insertion pin 56 is protruded to receive the negative bar 16 conveyed by a conveying unit (not shown). At this time,
The magnet 62 is turned on, and by inserting the insertion pin 56 into the pin hole 32 formed in the negative bar 16, the negative bar 16 is positioned and held on the lifting plate 54.

Thereafter, the drive rod 4 of the air cylinder 48 is
By contracting 8A and lowering the lift plate 54,
When this negative bar 16 is put on the pasting stage 42,
The long hole 34 of the negative bar 16 is placed on the ground-side end of the negative film N. Thus, the negative bar 16 is positioned with respect to the negative film N. When the negative bar 16 is taken out from the pasting stage 42 together with the negative film N by a carrier (not shown), the magnet 62 serving as an electromagnet may be turned off.

When the negative bar 16 is placed on the end of the negative film N on the ground side, the attaching device 40
The rodless cylinder 64 is driven to
Is moved on the adhesive tape 38 of the negative bar 16.

The pressing roller 84 is a rodless cylinder 8
When the guide 6 starts to be driven, the guide 94 descends along the inclination of the guide 94 and then moves from the small table 82 to the negative bar 16 placed on the sticking table 42. Thereafter, the negative bar 16 moves on the adhesive tape 38 while pressing the adhesive tape 38.

The pressing roller 84 is formed of an elastic body and is pressed downward by the urging force of the coil spring 92.
Elastically deform so as to block

As a result, as shown in FIG. 5, the pressure-sensitive adhesive tape 38 is pushed into the long hole 34 by the pressing roller 84 and adheres while being pressed against the surface of the negative film N disposed below the negative bar 16. Is done. Therefore, even if the space between the long holes 34 formed in the negative bar 16 is wide, the adhesive tape 38 adheres to the negative film N over a wide area in the long hole 34, and the negative film N is securely adhered to the negative bar 18. Can be attached.

In order to push the adhesive tape 38 into the long hole 34, a roller having a projection formed on the outer periphery in accordance with the width of the long hole 34 may be used. The processing cost is higher than that of the pressing roller 84 formed of an elastic body. At this time, it is necessary to form a rectangular opening as the long hole 34.

On the other hand, by using a crown roller whose outer peripheral portion is formed of an elastic material as the pressing roller 84, the adhesive tape 38 can be pressed into an opening of an arbitrary shape.

In this way, the negative bar 16 to which the negative film N has been attached rises together with the lifting plate 54 by extending the drive rod 48A of the air cylinder 48 of the attachment / detachment device 44, and the suction by the magnet 62 is prevented. It is released.

On the other hand, when the negative film N is placed on the sticking stage 42, the negative film N is overlaid so that the predetermined negative film N faces upward. That is, the two negative films N are stacked and attached to the negative bar 16 such that the negative film N to be peeled off from the negative bar 16 first is on the negative bar 16 side.

The negative bar 16 includes a negative film N.
Slot 3 so that the slot 34 does not overlap the overlapping portion of
4 are drilled. Thereby, the negative film N is easily peeled off near the overlapping portion of the negative film N.

When peeling the negative film N which has been stacked and adhered to the negative bar 16 in this manner, a peeling blade 98 is inserted between the negative film N and the negative bar 16 arranged on the upper side, and this blade 98 is attached to the negative bar 16. The film is moved to the overlapping portion of the negative film N along the longitudinal direction.

As a result, as shown in FIG. 6, first, the negative film N stacked on the upper side is peeled off from the negative bar 16, and when the blade 98 reaches the overlapping portion of the negative film N, the upper negative film already peeled off. The end of the lower negative film N is wound by the film N. At this time, since the adhesive tape 38 is not attached to the overlapping portion of the negative film N, the end of the lower negative film N is easily rolled.

Therefore, there is a gap between the negative film N on the lower side and the negative bar 16 in which the blade 98 is securely inserted.
The lower negative film N is also reliably peeled off from the negative bar 16 following the upper negative film N.

As described above, in the present embodiment, the negative film N can be securely attached to the negative bar 16, and even when the two negative films N are arranged and attached to the negative bar 16, each negative film N can be attached. The film N can be reliably peeled from the negative bar 16.

Note that the present embodiment described above does not limit the configuration of the present invention. The present invention can be used in any configuration as long as an original film is attached using an opening formed in a plate material.

[0081]

As described above, according to the present invention, when two original films are arranged side by side and attached to a plate, by providing an overlapping portion, each original film can be reliably peeled off from the plate. In addition, when the adhesive tape attached to the plate material is attached to the original film, the crown roller formed of an elastic body is used as a pressing roller, so that the adhesive tape can be attached to the original film reliably, An excellent effect that the original film can be reliably prevented from peeling off from the plate material is obtained.
