Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for developing a photosensitive material, which is developed by peeling off the cover base of the photosensitive material, which is laminated to a support via a photosensitive layer.

For example, it consists of a support such as an aluminum plate, a photosensitive layer containing a photocurable substance, and a light-transmitting cover base such as a polyethylene terephthalate film.
A photosensitive material in which the exposed portion of the photosensitive layer hardens and adheres to the support, and the unexposed portion adheres to the cover base, can be developed as a resist image on the support by peeling off the cover base. Ru.

Conventionally, developing devices for such photosensitive materials include:
There is a method that attaches adhesive tape to the surface of the cover base, winds it up, peels off the cover base, and develops it, but in addition to requiring an extra material called adhesive tape, it also requires an adhesive tape supply mechanism. The cost T-g and running cost of the device itself are high, and there are also concerns about troubles that may occur if the adhesive strength of the adhesive tape and cover base is insufficient.

Another conventional device uses a roller with suction holes on its periphery to attract the cover base and peel it off for development, but this requires a vacuum pump and air control mechanism, making the device large and The cost was high.

SUMMARY OF THE INVENTION An object of the present invention is to provide a developing device that eliminates the drawbacks of the conventional devices described above and can reliably peel off a cover base with a simple mechanism without requiring extra materials such as adhesive tape.

The object of the present invention is to provide an apparatus for developing a photosensitive material by peeling off a cover base of a photosensitive material laminated to a support via a photosensitive layer, which includes a peeling roller and a brush roller having a larger diameter than the roller. It consists of a peeling roller combined in a skewer shape, and a nip roller made of a plurality of individual rollers or a skewer-shaped roller in contact with each of the peeling rollers, and the peeling roller rotates in a direction opposite to the direction in which the photosensitive material is conveyed. The brush roller is provided so as to be in contact with the surface of the cover base in the conveyance path of the photosensitive material, the tip of the cover base is peeled off by the brush roller, and the peeled cover base is pinched and conveyed by the peeling roller and the nip roller. This is achieved by configuring the device so that it can be pulled away from the support body.

The present invention will be described in detail below based on its embodiments.

First, the main components of the present invention will be described.

The peeling roller, which is a component of the present invention, is a skewer-like combination of a peeling roller 1 and a brush roller 2, as illustrated in FIG. There is also no big deal.

The separating roller 1 can be made of an elastic material such as rubber or soft plastic, or a material with a roughened surface even if it is not elastic. It is preferable to use a material that has so-called frictional properties that cause friction with the cover base surface.

The brush roller 2 needs to be in contact with the cover base with relative rigidity, and the rigid elastic bristles may be long, but the soft elastic bristles are preferably short.

Further, for the purpose of peeling off the cover base, better results can be obtained by using a bristle material with a bent tip 3, as illustrated in FIG.

It does not matter whether the bristle material is a natural material or an artificial material; for example, a bundle of metal or plastic wires, or a material formed into a brush shape can also be used.

As illustrated in FIG. 3, the nip roller which is a component of the present invention may be constructed by independently providing a plurality of individual rollers 4, each of which is in pressure contact with the opposing separation roller 1. Alternatively, as illustrated in FIG. 4, a skewer-shaped roller 5 with stepped grooves may be used so that each convex portion comes into pressure contact with the opposing separating roller 1.

Any material can be used for the nip roller, such as metal, plastic, or rubber.

Hereinafter, the present invention will be described in detail using one embodiment of the apparatus as a representative example, the main part of which is illustrated in FIG.

The apparatus shown in FIG.
Cover base 1 with support body 12 on top on the conveyance path consisting of 5B
3 is passed through with the cover base 13 facing downward, and this is for peeling off the cover base 13, and has a structure in which a peeling roller 16 and a nip roller 17 are provided below the guide plate 15 in the conveyance path.

As shown in FIG. 6, the peeling roller 16 is made of a metal core roller 24 which has stepped thick protrusions 21, thin protrusions 22, and recesses 23, and is made of rubber having many protrusions on its surface. A sheet 25 is wound around a thin convex part 22 to form a separating roller 1, and a cloth tape 26 having a large number of curved plastic filaments implanted at the tip is wound around a thick convex part 21 to form a brush roller 2. be.

The nip roller 17 is a single roller 4 as shown in FIG.
is made of plastic and pressed by a spring 18 to create a nip pressure between it and the separating roller 1.
There is a peeling rib 19A between the rollers 17 and 17.
This is provided.

Peeling roller 1 and brush roller 2 in the peeling roller
A peeling rib 19B is formed in the recess 23 forming a groove between the
This is a temporary arrangement.

As shown in FIG. 7, the development action for peeling off the cover base using the device trowel configured in this way is performed by rotating the tip of the photosensitive material 11 that is being fed in the opposite direction to the conveying direction. By contacting the brush roller 2 of the roller 16, the cover sheet 13 is peeled off from the support 12, and the tip of the peeled cover sheet 13 is sent along with the rotation of the brush roller 2, and when it comes into contact with the nip roller 17, As a result of the rotation of the nip roller 17 and the peeling roller 1 that is in contact with the nip roller 17, the sheet is gripped by the nip roller 17 and the peeling roller 1 that is in contact with the nip roller 17, and at its exit, it is wound onto the peeling roller 16 by the peeling rib 19B and onto the nip roller 17 by the peeling rib 19A. It is sent downward while being prevented from touching.

Of the guide plates, 15B is movable and remains at the position indicated by the chain line until the cover sheet 13 is sandwiched between the needle roller 17 and the peeling roller, but when it is sandwiched, it moves upward to the position indicated by the solid line. Prevents movement and damage to the image developed on the support surface.

Therefore, it is preferable that the pair of delivery rollers 20, 20 be located slightly above.

In the above embodiment, the guide plate 15B was made movable upward to move the position where the photosensitive material is conveyed upward in order to prevent the brush roller from damaging the developed surface. The conveying direction may remain S and the peeling roller may move downward.

Also, it can be used without moving the guide plate or peeling roller.
As shown in FIG. 8, until the cover base 13 is peeled off at the leading end of the photosensitive material, the length of the part extending ahead of the conveyance rollers 14, 14 is short, so it does not bend and by the time it passes the peeling roller 16. Since the portion to be delivered first becomes longer and bends, it may be guided somewhat upward by the delivery rollers 20, 20 and separated from the peeling roller 16.

Roller 4 or roller 5, each component of the nip roller shown in FIG. 3 or 4, can capture the side edge of the peeled cover base if it is positioned at the photosensitive material passing position. Cover base processing is performed more smoothly.

Since the present invention is a peeling and developing device as described above, it is possible to reliably peel off the cover base with a simple mechanism without requiring extra materials such as adhesive tape as in conventional devices, and has practical effects. is extremely large.
