Description

The present invention relates to a proposal of an automatic plate making apparatus most suitable for newspaper printing, and more specifically, it relates to a plate feeding section, an exposure section, a transport and plate material temporary stacking section, a development processing section and a plate material stacking section. The present invention relates to a proposal of an automatic plate making apparatus in which parts and sections are arranged in series.

According to the automatic plate making apparatus of the present invention; a required number of unexposed plate materials are stacked on a predetermined supporting base, and a required number of film originals having a printing image are stacked on a predetermined supply tray in the printing order. If it is operated by automatic operation, unexposed plate material is supported on the plate material holder and driven and arranged to the exposure part, and it is adsorbed and held by the original plate holder on the predetermined surface of the plate material. The film original plate thus formed is driven and arranged, and both are vacuum-closed to each other to be exposed to light, and the arrangement of the film original plate on a predetermined surface of the plate material and both (film original plate and plate material)
After the exposure is completed, the exposed film original is discharged to the outside of the system, and the printing material on which the image of the film original is printed is transferred from the exposure section to the automatic developing machine. Is fed to the plate and subjected to the required development processing, and is further accumulated in the plate material accumulating section. The operation of temporarily accumulating in the plate material temporary accumulating section can be repeated in a required number (until the entire film original plate loaded on the supply tray is drivingly arranged in the exposing section). By designing and configuring in consideration of the above,
It has extremely high reliability and speed.

a) The plate material holder is supported and arranged in the exposure section, and the plate material holder is supported so as to be reciprocally movable between the exposure section and the plate supply section, so that the plate material holder is held at a predetermined position in the plate supply section and stands by. It was designed and constructed so that the unexposed plate material could be picked up and received, and then returned to the exposed section again.

Since the plate material holder is configured to reciprocate between the exposure unit and the plate feeding unit in this manner, there is no concern about the transfer of the plate material when the plate material having a large area is supplied to the exposure unit. Expulsion and simplification of the passing operation to improve the reliability of the operation, and at the same time to achieve the speeding up of the operation, and also to simplify the mechanism and structure related to the passing of the plate material. Is.

Since the plate material holder is configured as described above, as a preparatory work before operating the apparatus of the present invention, simplification of the stacking work of the plate materials by the manual work on the plate feeding section and the operation of the plate feeding section It also aims to achieve both simplification and high reliability.

That is, for the stacking work of the plate materials on the plate feeding section manually, it is sufficient to simply stack the plate materials at a predetermined position, and in terms of the operation of the plate feeding section, the plate materials are stacked at a predetermined position. The uppermost one of the placed plate materials may be simply adsorbed to the plate material adsorbent without any fine position regulation, and the plate material adsorbent may be allowed to stand by at a certain position. This is because the adsorbent may simply be moved up and down).

b) In the structure of the plate material holder itself, the plate material is automatically positioned at the reference position on the plate material holder surface by providing a means for aligning the plate material in a certain direction on the plate material holder. I am doing it.

With such a configuration, the plate material holder is completely released from the trouble of receiving the plate material while regulating the position of the plate material in the operation when receiving the plate material from the plate material adsorbent in the plate feeding section, Simultaneous simplification and speeding up of the transfer of plate material from the plate supply section to the plate material holder are achieved.

c) The exposure unit, the transport and plate material temporary stacking unit, and the automatic developing machine are provided adjacent to each other, and in the transport and plate material temporary stacking unit, the plate material received from the exposure unit is delivered to the automatic developing machine as it is, It was designed so that it can be arbitrarily selected whether it should be retained in the plate material temporary accumulation section.

This makes it possible to freely select whether to directly send the plate material from the exposure section to the automatic developing machine or to retain the plate material in the plate material temporary stacking section. It is designed to be adaptable to high working styles.

d) The operation of delivering the plate material from the exposure section to the transport / plate material temporary accumulating section is configured so as to be performed reliably and speedily.

That is, while providing a transport roller adjacent to the plate material holder, arranging the plate material holder surface and the transport roller on the same height surface, and raising the rear end of the plate material by a very small width, A claw for feeding the plate material is applied, and the claw is driven to feed the plate material by a predetermined distance, whereby the front end of the plate material is gripped by the transport roller.

By doing so, the plate material that has been exposed is released from the factor of operational anxiety such as being transported in the space, and is delivered to the next step reliably and speedily.

A detailed description will be given below with reference to the accompanying drawings showing one embodiment.

As shown in FIG. 1, the plate making apparatus of the present invention has a plate supply section (A), an exposure section (B), a conveyance and plate material temporary accumulation section (C), and a development processing section (D) in a predetermined processing order. ) And the plate material accumulating section (E) are arranged in series, and they are arranged with a necessary relation so that the above-mentioned operation is automatically and continuously repeated. This will be described in detail below.

The plate feeding mechanism is shown in FIG. 2, and the unexposed plate material (P) is used.
The plate material support table (1) on which the required number of sheets are stacked is always held at a required height by a known arbitrary position regulating mechanism (not shown), so that the uppermost plate material (P) is always kept at a predetermined height. Maintained.

The plate material adsorbent (2) equipped with a suction cup (200) is driven by an air cylinder (201) and descends onto a plate material support base (1), where the suction plate (200) causes the top plate material ( P)
Is adsorbed, and the air cylinder (201) is driven again to return it to a predetermined position (Fig.).

Then, the plate material holder (3) standing by at the predetermined position of the exposure section (B) is driven by the air cylinder (300) to enter under the plate material adsorber (2), and there, the suction cup (200). The adsorption by the plate is released and the plate material (P) is transferred onto the plate material holder (3).

The plate material (P) transferred onto the plate material holder (3) is provided with means (301) provided in two directions (for example, the front side and the right side) for moving the plate material in a required direction, and two directions (2) opposed thereto (301). It is always positioned at a predetermined position on the plate material holder (3) by means (302) for receiving the plate material provided on the opposite side and the left side.

A supplementary explanation of the plate material positioning means will be omitted. The detailed illustration of the means (301) for moving the plate material in the required direction (the direction in which the means (302) for receiving the plate material is provided) is omitted. The L-shaped material is attached to the tip of the piston rod of the air cylinder, and the plate material (P)
When is released from the suction cup (200) and drops onto the plate material holder (3), the two ends of the plate material (P) are arranged on the L-shaped material, where the air cylinder is placed. When the other end of the plate material comes into contact with the means (302) for receiving the plate material, the signal is immediately sensed and the air cylinder is stopped. There is.

When the plate material (P) is positioned as described above, the plate material (P) is moved to the plate material holder (3) by a vacuum suction means (not shown).
It is adsorbed and held by (Fig.).

Then, the plate cylinder holder (3) is returned to a predetermined position of the exposure section (B) by driving the air cylinder (300) (Fig.).

By the above, the unexposed plate material (P) is arranged at a predetermined position of the exposure section (B), and in parallel with this, the unexposed film original plate of the exposure section (B) is arranged as shown in FIG. It is placed in place.

On the side of the lamp house (6), which suspends the exposure lamp (4) above and supports the original plate holder (5) below it, the film original plate (F) is printed in the order of printing. Therefore, the film original plate supply plate (7) on which the required number of sheets are set is arranged (Fig.), And the supply plate (7) is
It is driven by a driving means (not shown) and is arranged directly below the original plate holder (5) (FIG.).

Then, the original plate holder (5) descends onto the film original plate supply tray (7), where the uppermost film original plate (F) is adsorbed and moved up again to separate from the film original plate supply plate (7). On the other hand, the original film supply plate (7) is also returned to its original position. In other words, move out of the ramp house (6) (Figure).

Subsequently, the original plate holder (5) is replaced by the plate material holder (3).
The film original plate (F) sucked and held by the original plate holder (5) and the plate material (P) sucked and held by the plate material holder (3) are vacuum-closed by a vacuum contact mechanism (not shown). (Figure).

Following this, the exposure lamp (4) is turned on and the image on the film original plate (F) is transferred to the plate material (P).

Incidentally, among the above, in the adsorption of the film original plate (F) by the original plate holder (5), a pair of position regulating pins (700) erected at a predetermined position of the film original plate supply plate (7).
Of the film original plate (F) from the film original plate supply tray (7) to the original plate holder (5) when it is fitted into a hole (not shown) of the original plate holder (5) opened at the corresponding position. As a result, the film original plate (F) is positionally regulated and adsorbed at a predetermined position of the original plate holder (5).

Although illustration is omitted because it can be designed very naturally, in the above description, regarding the loading and unloading of the film original plate supply plate (7) to and from the lamp house (6), the film original plate supply plate (7) is used. It can be movably supported by a guide frame, and can also be made by reciprocally driving the supply tray (7) with an air cylinder. Also, the lowering and upward movement of the original holder (5) are basically With the same configuration as described above, the purpose can be achieved.

By the above-described operation, the image of the film original plate (F) is printed on the first surface of the plate material (P). Following this operation, the original plate holder (5) is moved upward and the plate material holder (5) is moved. 3)
The original plate holder (5) is precisely positioned and arranged on the second surface of the plate material (P) by the precision driving means of the original plate holder (not shown),
The second side is printed by the same operation as the side printing, and the original plate holder (5) is returned to the original position (first side) by the precision driving means (the original plate is printed on the plate surface). It is assumed that the image is attached on two sides).

Then, the film original discharge tray (8) is drivingly arranged under the original holder (5), and the adsorption of the film original (F) by the original holder (5) is released there, and the film original (F) is ejected. Dropped into the dish (8).

The film original plate discharge tray (8) that has received the film original plate (F) is returned to the original position (Fig.).

On the other hand, the exposed plate material (P) is transferred to the next step as shown in FIG.

That is, the air cylinder (9) embedded at a predetermined position on the end of the plate material holder (3) operates (the piston rod extends) to lift the plate material (P) by a very small width.

Then, the plate material feeding claw (10) is driven into by the driving means (11), and the piston rod of the air cylinder (9) is contracted therein, and the plate material feeding claw (10) becomes the plate. Send the material (P) a required distance,
As a result, the leading edge of the plate material (P) is held by the entry roller (120) of the conveying means (12) connecting the exposure section (B) and the development processing section (D), and conveyed to the development processing section (D). (Figure)

The plate material feeding claw (10), which has delivered the plate material (P) to the conveying means (12), is returned to its original position by the driving means (11) (Fig.).

On the other hand, the plate material (P) conveyed by the conveying means (12) is sent to an automatic developing machine (13), where it undergoes a required developing process, and a plate stand arranged at the rear part of the automatic developing machine (13). You can lean against (14).

By the way, in the case of newspaper printing, for example, based on the prepared film original plate, only the first side on the plate material is printed in advance, and when the film original plate for the second side is ready,
The work form of printing the second side may be used.

In preparation for such a case, the development processing section (D) is provided.
The plate material temporary accumulating section (C) before the above, and the case of using the temporary accumulating section (C) will be described with reference to FIG.

When the exposed printing plate is directly applied to the automatic processor (13), the piston rod (150) of the air cylinder (15) contracts and the forced arm (1)
