[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for producing a photosensitive resin plate for flexographic printing such as corrugated board printing, flexible packaging printing, film printing, preprint printing and label printing, and in particular, before relief exposure. ITR (In which the plate making process is performed after the photosensitive resin plate is attached to the printing sleeve.
A method for sticking a photosensitive resin plate on a printing sleeve in the The Round) manufacturing technology, and an apparatus for carrying out this method.

[0002]

2. Description of the Related Art A sheet-shaped photosensitive resin plate is used as a plate material for letterpress printing represented by flexographic printing.
AFP (trade name, manufactured by Asahi Kasei), which is one of the photosensitive resin plates, is a typical product.

As a sheet-shaped photosensitive resin plate structure, in JP-A-2000-155418, a transparent polyester film having a thickness of 125 μm is used as a support, on which a thermoplastic elastomer and at least one ethylenic unsaturated are formed. For the purpose of coating a photosensitive resin composed of a photosensitive elastomer composition containing a compound and at least one initiator sensitive to ultraviolet rays to a thickness of about 3 mm, and making the surface layer of the photosensitive resin contact with a negative film smoothly. , Provided with a thin flexible film layer called a slip layer or a protective layer.

Further, in Japanese Patent Laid-Open No. 11-153865, for the purpose of not using a negative film, a structure in which a thin layer abradable by an infrared laser is provided on the surface layer of a photosensitive resin (digital photosensitive resin Called the edition).

To make a flexographic printing plate from such a sheet-shaped photosensitive resin plate structure, first, an entire surface is exposed to ultraviolet light (called back exposure) through a film support to form a uniform photocurable layer. , Then, through a transparent image carrier such as a negative film that selectively transmits ultraviolet rays from the photosensitive resin layer side, or in the case of a digital type photosensitive resin plate, an image that has become digital information is burned off with an infrared laser. Ultraviolet light exposure (called relief exposure) is applied through a thin layer on which an ultraviolet light transmitting portion is formed (called abrasion), and the exposed photosensitive resin is photo-cured to form an image. A relief image is formed by washing and removing the photosensitive resin with a solvent developing solution such as a chlorine-based solvent or a non-chlorine-based solvent or an aqueous developing solution (referred to as development). After that, the photosensitive resin plate is dried to evaporate the developing solution remaining on the photosensitive resin plate, and subsequently the surface adhesion of the photosensitive resin plate is reduced by finishing treatment (photochemical treatment or chemical treatment). To obtain a photosensitive resin printing plate whose physical strength is improved to a level capable of withstanding printing stress.

In order to print the sheet-shaped photosensitive resin printing plate obtained by the plate-making process as described above, the photosensitive resin printing plate is directly attached to the plate cylinder of a printing machine by using a double-sided tape or the like, Alternatively, the photosensitive resin printing plate is attached to a carrier sheet or a printing sleeve using a double-sided tape or the like, and the carrier sheet or the printing sleeve is attached to a printing machine.

When a photosensitive resin printing plate is attached to a desired position of a printing press plate cylinder, a carrier sheet, or a printing sleeve, a method for aligning the position using a CCD camera or the like and a device for carrying out this method are used. Sometimes.

However, the above method relies on human hands for most of the work, and when the positions of the sticking start end and the sticking end are misaligned, the photosensitive resin printing plate is transferred to the printing press cylinder,
Peel off the carrier sheet or printing sleeve,
It is necessary to perform the pasting work again, which imposes a great load on the worker.

Then, before the exposure or only in advance the back exposure (the photosensitive resin plate at this stage is referred to as a photosensitive resin raw plate) is attached to the printing sleeve. , The photosensitive resin plate attached to this printing sleeve is subjected to ablation drawing of a digitized image by an infrared laser, relief exposure is performed through the image, and development, drying, and finishing processes are performed. An ITR technique has been proposed in which the printing sleeve is attached to the printing machine as it is after being performed. With this ITR technique, the work of attaching the photosensitive resin printing plate becomes unnecessary, and the alignment work on the printing machine can be easily performed.

[0010]

However, even the above-mentioned ITR technique is not completely free of problems, and many steps are required in the step of attaching the photosensitive resin plate to the printing sleeve. .

The photosensitive resin plate is usually attached to the printing sleeve with a butting gap of about 3 mm or less. This is because overlapping of the abutting edges of the photosensitive resin plate is a serious problem in the later plate making process and printing, but the abutting gap and the outer edge of the photosensitive resin plate are not exposed to the double-sided tape. Become. If the double-sided tape remains exposed, the double-sided tape will be exposed to the developing solution or the plate cleaning solution during the development process with the developing solution applied after the attachment or the printing plate cleaning after printing, and the photosensitive resin This causes serious problems such as the (printing) plate peeling from the printing sleeve. In order to prevent the occurrence of this problem, it is necessary to seal the abutting gap and the outer edge of the photosensitive resin plate before development, and this work also depends on human hands.

[0012] The present invention focuses on such problems in the prior art, and an object thereof is to greatly reduce the load on the operator in the work of sticking the photosensitive resin plate on the printing sleeve.

[0013]

In order to solve the above-mentioned problems, the present invention is directed to the production of a photosensitive resin printing plate by attaching a photosensitive resin raw plate before exposure to a printing sleeve and then performing a plate making process.

[0025]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be specifically described below. In particular, a photosensitive resin plate pasting device corresponding to one embodiment of the device of the present invention and capable of easily carrying out the method of the present invention will be described with reference to the drawings.

FIG. 1 is a view showing the schematic arrangement of a photosensitive resin plate pasting apparatus according to the present invention. As shown in FIG. 1, the apparatus 1 is roughly divided into a double-sided tape sticking mechanism 2 serving as a tape sticking means, a photosensitive resin plate sticking mechanism serving as a plate sticking means having a photosensitive resin plate pressing roller 102, and coating. It is configured by the seal material applying mechanism 3 serving as a means.

The sleeve 5 is removably and rotatably attached to the apparatus 1 by a sleeve attachment member 101 attached to a rotary shaft. In this state, a double-sided tape 202 is attached to the outer peripheral surface by a double-sided tape attaching mechanism 2. Attached. The double-sided tape 202 is preferably selected from a base material having appropriate elasticity depending on the combination of the material to be printed and the printing machine.

After the photosensitive resin plate 4 is attached by the photosensitive resin plate attaching mechanism via the double-sided tape 202 attached to the surface of the sleeve 5, the abutting gap and the outer edge (of the sleeve 5) of the photosensitive resin plate 4 are attached. Surface and photosensitive resin plate 4
The corner formed between the edge and the edge of the
Then, the seal material 304 is applied by the seal material applying mechanism 3.

Hereinafter, each mechanism will be described in detail. The embodiment of the present invention is not limited to the mechanism described below.

FIG. 2 shows a state in which the double-sided tape 202 is attached to the sleeve 5 by the double-sided tape attaching mechanism 2. First, the double-sided tape attaching mechanism 2 sleeps 5.
It moves toward the double-sided tape 202 until it contacts.
This amount of movement is calculated from data such as the dimensions of the sleeve 5 and the thickness of the double-sided tape 202, which are input in advance by a worker into a control device (not shown). This makes it possible to use the sleeve 5 having a desired size and the double-sided tape 202 having a desired thickness.

Subsequently, the sleeve mounting member 101 is driven by a motor capable of controlling the rotation speed such as a pulse motor, and the rotation angle is also detected. At this time, the double-sided tape 202 fed from the double-sided tape roll 201 while being applied with the braking force by the braking roller 204 is guided by the guide roller 205 to the double-sided tape pressing roller 206 serving as a pressing member.

The double-sided tape pressing roller 206
While the double-sided tape 202 is pressed against the sleeve 5 and adhered thereto, the release paper 203 is peeled off from the double-sided tape 202 by the release paper drive roller 207 serving as a release member. The peeled release paper 203 is collected in the release paper collection basket 210. At this time, the release paper 203 may be collected by a winding roll method instead of the basket method shown in the drawing.

Next, both sides of the rotation angle calculated by subtracting the cutting allowance of the double-sided tape (the distance between the double-sided tape pressing roller 206 and the double-sided tape cutting cutter 209) from the dimension of the sleeve 5 previously input by the operator. Tape 2
The sleeve fixing jig 101 once stops rotating when 02 is pasted. Then, the double-sided tape cutting cutter 209 cuts the double-sided tape 202 in the width direction. At this time, the bite amount of the double-sided tape cutting cutter 209 is appropriately set, and is adjusted so that only the double-sided tape 202 can be cut without cutting the release paper 203. After that, the sleeve fixing jig 101 restarts the rotation, and the attachment of the double-sided tape 202 is restarted.

Before the cut portion of the double-sided tape 202 reaches the double-sided tape pressing roller 206, the double-sided tape attaching mechanism 2 moves to separate from the sleeve 5. This is to prevent the cut next double-sided tape from sticking to the sleeve 5. At the same time, the double-sided tape pressing roller 208 comes into contact with the double-sided tape 202, and the double-sided tape attaching mechanism 2 separates to bring the final end of the double-sided tape 202 into close contact with the sleeve 5. At this time, the adhesive force between the double-sided tape pressing roller 208 and the double-sided tape 202 is sufficiently weaker than the adhesive force between the double-sided tape 202 and the sleeve 5, so that the double-sided tape pressing roller 208.
The surface of is processed.

The end portion of the cut double-sided tape 202 on the side of the double-sided tape roll 201 is positioned in the vicinity of the double-sided tape pressing roller 206 while maintaining the adhesive state to the release paper 203 held by the release paper driving roller 207. . Therefore, when the series of operations on the sleeve 5 is completed and a new sleeve 5 is mounted on the sleeve mounting member 101, the double-sided tape 202 can be easily and surely attached.

At this time, the width of the double-sided tape 202 does not necessarily have to be the same as the width of the sleeve 5 (the axial length of the sleeve 5). Rather, the width of the double-sided tape 202 is often narrower than the width of the sleeve 5. In such a case, after the double-sided tape 202 is pasted around the sleeve 5 once, the double-sided tape pasting mechanism 2 is moved in the width direction (the axis of the sleeve 5 by an amount corresponding to the width of the double-sided tape 202 input by the operator in advance). Move in the direction of your heart) and repeat the double-sided tape application operation. Thereby, the double-sided tape 202 having a desired width can be attached to the sleeve 5 having a desired size.

The width of the sleeve 5 is double-sided tape 202.
It is also possible to provide a plurality of double-sided tape sticking mechanisms 2 to which double-sided tapes 202 having different widths are attached and to use the double-sided tape according to the double-sided tape sticking width. Similarly, the width of the sleeve 5 must be wider than the width of the photosensitive resin plate 4, but it does not necessarily have to be the same. In this case, the double-sided tape 202 has the sleeve 5 specified by the operator in advance in accordance with the width of the photosensitive resin 4.
It may be attached to a desired position of.

In the double-sided tape attaching mechanism 2 configured as described above, the double-sided tape 20 is attached when the double-sided tape 2 is attached to the surface of the sleeve 5 or when the work is completed.
It is necessary to press 2 on the sleeve 5 or move it away. Therefore, the double-sided tape attaching mechanism 2 and the sleeve 5
Are configured to be relatively close to or apart from each other. In particular, in this embodiment, the sleeve 5 is made immovable in the horizontal direction, and at least the double-sided tape pressing roller 206 of the double-sided tape attaching mechanism 2 can be moved toward and away from the sleeve 5.

In FIG. 3, the photosensitive resin plate 4 is a double-sided tape 202.
It is the figure which showed the state pasted on the sleeve 5 via. First, the sleeve mounting member 101 is moved so that the height of the outer peripheral surface of the double-sided tape 202 attached to the sleeve 5 is the same as the surface of the photosensitive resin plate 4 on the support side. At this time, the amount of movement of the sleeve fixing jig 101 is calculated based on data such as the dimensions of the sleeve 5 and the thickness of the double-sided tape 202 which are input by the operator in advance.

Then, the photosensitive resin plate pressing roller 102, which serves as a pressing member, moves to a position where an appropriate gap is maintained with the double-sided tape 202 attached to the outer peripheral surface of the sleeve 5. At this time, the photosensitive resin plate pressing roller 102
The movement amount of is calculated based on data such as the thickness of the photosensitive resin plate 4 which is input in advance by the operator. Thereby, the photosensitive resin plate 4 having a desired thickness can be attached to the sleeve 5.

Subsequently, the photosensitive resin plate 4 is driven by a moving member (not shown) and straightened to the sleeve 5 along the guide guide 103 until it comes into contact with the double-sided tape 202 and the photosensitive resin plate pressing roller 102. That is, it is sent out in a direction orthogonal to the axial center of the sleeve 5. Then, when the sleeve mounting member 101 starts rotating, the photosensitive resin plate 4 is attached to the sleeve 5 via the double-sided tape 202 while being pressed by the photosensitive resin plate pressing roller 102. At this time, the surface of the photosensitive resin plate pressing roller 102 is processed so as not to damage the thin layer abradable by the infrared laser of the photosensitive resin plate 4.

Next, FIG. 4 is a view showing a state in which the sealing material 304 is applied to the butting gap and the outer edge of the photosensitive resin plate 4 attached to the sleeve 5. As the sealing material 304, for example, silicone rubber can be used, but the sealing material 304 is not limited to this, and has a property such that it is not dissolved, peeled, impregnated, permeated, etc. with a developing solution or a plate cleaning solution. As long as you have, you are not limited.

When the photosensitive resin plate 4 is attached to the sleeve 5, a gap 401 is formed at the abutting portion between the end portions 4a of the photosensitive resin plate 4. Therefore, the gap 401
The double-sided tape 202 attached to the surface of the sleeve 5 is exposed. The double-sided tape 202 is also exposed from between the surface of the sleeve 5 and the edge portion 4b of the photosensitive resin plate 4. Therefore, the sealing material 3 is provided along the gap 401 and the edge 4b.
By applying 04 to cover the double-sided tape 202, the double-sided tape 202 can be used when a post-process represented by a developing process is performed.
It is possible to prevent a failure from occurring in the.

First, the photosensitive resin plate pressing roller 102, which has completed the attachment of the photosensitive resin plate 4, moves to a predetermined retracted position. Next, the nozzle 30 that discharges the sealing material
1a and a sealing material application head 301 having an opening / closing member for controlling discharge and stop of the sealing material from the nozzle 301a
Is driven by the coating head driving mechanism 303 to move to one edge 4b of the photosensitive resin plate 4 and stop. Subsequently, the sleeve mounting member 101 rotates while discharging the sealing material 304 from the sealing material applying head 301, and the edge portion 4b of the photosensitive resin plate 4 and the sleeve 5 cover the double-sided tape.
The sealing material 304 is applied to the boundary surface (corner) of the.

At this time, the seal material 304 is supplied to the seal material applying head 301 from the seal material tank 302 serving as a seal material accommodating member. Further, the discharge amount of the sealing material 304 is constant and controlled to an appropriate amount. For example, if the applied sealing material 304 is too small, the double-sided tape will be exposed, and if it is too large, printing will be hindered.

The sleeve mounting member 101 stops rotating after one rotation. Subsequently, the sealing material application head 30
1 is driven by the coating head driving mechanism 303, and while applying along the axis of the sleeve 5, the sealing material 304 is applied to the butting gap 401 of the photosensitive resin plate 4. Then, the seal material application head 301 stops when reaching the other edge portion 4b, the sleeve mounting member 101 subsequently rotates, and the seal material 304 is applied to the remaining edge portion 4b, and the processing is completed.

After this, the sleeve mounting member 10 of the present device 1
When the sleeve 5 attached to No. 1 is removed, it is possible to provide the same state from abrasion drawing with an infrared laser, plate making processing such as exposure with ultraviolet rays and development with a developing solution to printing and subsequent storage. It is possible to obtain a sleeve to which a photosensitive resin plate is attached.
