Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention The present invention relates to the proposal of an automatic plate making device that is most suitable for newspaper printing. At the same time, if the required number of film masters with images for printing are loaded in the specified supply tray according to the printing order, the unexposed plate material is transferred to the plate material by automatic and continuous operation. The film master is suctioned and held by the holder and driven to the exposure section, and the film master which is suctioned and held by the master holder is driven and placed on a predetermined surface of the plate material, where the two are brought into close vacuum contact and exposed to light. Then, the film master is placed on a predetermined surface of the plate material and the two are brought into close contact with each other as many times as necessary, and when the exposure is completed, the film master in the exposed area is discharged out of the system, and the plate material in the exposed area is The plate material is transferred to an automatic developing machine, subjected to the necessary development processing, and placed in the plate material accumulation section.If necessary, the transfer of the plate material to the automatic developing machine is blocked, and the plate material is placed in front of the automatic developing machine. The unit operation of transferring the plate material to the Vi accumulating section is repeated a necessary number of times (until all the film originals loaded on the supply tray are driven and arranged in the exposure section). This paper relates to a proposal for an automatic plate making device.

Hereinafter, one embodiment will be described in detail with reference to the accompanying drawings showing one embodiment.

As shown in FIG.
A transport/plate material temporary accumulation section (C), a development processing section (D), and a plate material accumulation section (E) are arranged in series, and they are
The above-mentioned operations are arranged and configured with necessary relationships so that they are automatically and continuously repeated, and this will be described in detail below.

Figure f52 shows plate feeding Isokare, and unexposed plate material (P
) loaded with the required number of plates is always held at the required height by a known arbitrary position regulating device h1 (not shown), so that the uppermost plate (P) is always kept at a predetermined position. maintained at a height of

Sucking! (200) is driven by an air cylinder (201) to attach the plate material support base (1).
It descends to the top, where it suctions the uppermost plate material (P) with a suction cup (200), and returns to the predetermined position by driving the air cylinder (201) again (Fig. 2).

Subsequently, the plate material holder (3), which was waiting at a predetermined position in the exposure section (B), is driven by the air cylinder (300) and enters under the plate material suction body (2), where the suction cup ( 200> 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 moved by means (301) provided in two directions (for example, on the front side and on the right side) for moving the plate material in a desired direction, and in two directions opposite 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 far side and the left side.

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 retained by adsorption (Figure ■).

Subsequently, the plate material holder (3) returns to the predetermined position in the exposure section (B) by driving the air cylinder (300) (Fig. 2).

As described above, the unexposed plate material (P) is placed at a predetermined position in the exposure area (B), and in parallel with this, the unexposed film master is placed in the exposure area (B) as shown in Figure 3. placed in place.

On the side of the lamp house (6), which suspends an exposure lamp (4) above and supports an original holder (5) vertically movably below, film originals (F) are placed in the printing order. Therefore, the required number of original film supply trays (7
) is arranged (Figure ■), and the supply tray (7) is driven by a driving means (not shown) and is placed directly below the original holder (5) (Figure ■).

Next, the original holder (5) is attached to the film original supply tray (7).
), where it adsorbs the topmost film master (F), moves upward again and leaves the film master supply tray (7), while the film master supply tray (7) is also returned to its original position. It will be done. In other words, move out of the lamp house (6) (Figure ■).

Subsequently, the original plate holder (5) is replaced by the plate material holder (3).
It descends to the top and there, it is vacuum-adhered (not shown)? [By this, the film original plate held by suction on the original plate holder (5) (
F) and the plate material (P) held by suction on the plate material holder (3)
are vacuum-adhered (Figure ■).

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

Of the above, when the film master (F) is adsorbed by the master holder (5), a pair of position regulating bins (700) installed vertically at a predetermined position of the film master supply tray (7) are used.
However, the original plate holder (5) is opened in the corresponding position.
) when the film AIJ is inserted into the hole (not shown) in the film original supply tray (7) to the original holder (5).
By receiving and transferring i(F), the film original (F) is adsorbed in a predetermined position on the original holder (5).

Note that the illustration is omitted because it is naturally possible to design the original film, but in the above, the film original supply tray (7) is used to take the film original supply tray (7) into and out of the lamp house (6). This can be achieved by movably supporting the supply tray (7) with an id frame and reciprocating the supply tray (7) with an air cylinder.
) can also achieve its purpose by configuring it basically in the same way as above.

With the operation described above, ii! of the film original plate (F) is placed on the first side of the plate material (P)! The image is printed, but following this operation, the original plate holder (5) moves up and the plate material holder (3)
There, the original plate holder (5) is placed on the second side of the plate material (P) by a reciprocating drive means (not shown), and the second side is printed by the same operation as the printing of the first side. Then, the original holder (5) is returned to the original printing position (first side) by the driving means again.

Then, the film original ejection mold (8) is moved to the original holder (5).
), where the adsorption of the film original (F) by the original holder (5) is released, and the film original (F) is dropped into the film original discharge mold (8).

The film original discharge mold (8) that has received the film original ff1 (F) is returned to its original position (Fig. ■).

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

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

Then, the plate feeding claw (10) is driven by the drive means (11) and enters there, where the air
The piston rod of the cylinder (9) retracts, and the plate material feeding claw (10) feeds the plate material (P) a required distance, so that the tip of the plate material (P) is separated from the exposure area (B) and the developing area. It is held in the entry roller (120) of the conveying means (12) that connects the processing section (D), and the developing processing section (D)
(Figure ■■).

The plate material feeding claw (10) which has delivered the plate material (P) to the carrier J2 (12) is returned to its original position by the driving means (11) (Fig. ■).

On the other hand, the plate material (P) is transported by the transport means (12).
) is sent to an automatic developing machine (13), where it is subjected to necessary development processing, and then placed against a plate holder (14) marked at the rear of the automatic developing machine (13).

By the way, in the case of newspaper printing, for example, only the first side of the plate material is printed in advance based on the prepared film master plate, and as soon as the film master plate for the second side is ready,
The work may involve printing the second side.

The development processing section (D) was provided in preparation for such a case.
This is the temporary plate material accumulation section (C) in front of the plate material accumulation section (C), and the case where the temporary accumulation section (C) is used will be explained based on FIG.

When the plate material that has been exposed and baked is directly applied to the automatic developing machine (13), as shown by the solid line, the air sill-
The conveyor belt frame (17) whose posture is controlled by the forced arm (16) when the piston rod (150) of (15) contracts
is kept in a horizontal state, and the plate material (P) passes from the entry roller (120) over the conveyor belt frame (17).
It is sent to the automatic developing machine (13), but if it is temporarily accumulated, as shown by the iA line, the air shilling (15)
As the piston rod (150) extends, the front side of the conveyor belt frame (17) is flipped up by the force arm (16), cutting off the conveyance path, and the entry roller (
120), the plate material (P) slides down along the guide plate (18) and is stopped by one stopper.

Then, the air sill (20) is activated to raise the guide plate (18) to the plate stand side and move the plate material (P) to the plate stand (2).
Move to 1).

Note that predetermined information is input in advance into an operation panel (not shown) to determine whether the plate material is to be transported from the exposure section (B) to the development processing section (D) or to the temporary plate accumulation section (C). Needless to say, this can be done automatically by doing so.

As described in detail above, according to the present invention, with respect to the film original plate and plate material, which are printing materials, the film original plate is supplied in advance to the film original plate supply tray and the plate material to the plate material support base in accordance with the printing order. If this is done, the rest will be completely automatic, from supplying printing materials sheet by sheet to the exposure section, through exposure and printing, to development processing, and, if necessary, transporting plate materials to the temporary storage section. Therefore, it is particularly suitable as a plate-making device for newspaper printing, which requires urgent work.
