Description

[Detailed Description of the Invention] This invention is a method for transferring images on an original plate such as an original film to a light-sensitive material.
For example, the printing of a printing plate coated with a photosensitive agent is related to a printing apparatus used in the process, and particularly to a printing apparatus that can automatically print a test pattern outside the picture area of the printing plate. There are various aspects of the Ingiri plate, such as the degree of completion of the plate making and the quality of printing of printed matter using the plate.
In order to visually check the r1 picture area external pressure, various test patterns as shown in FIG. 6 are provided. Usually, these test patterns are pasted on a transparent mount and printed with the color-separated manuscripts of each deity at the 1st stage of master production, or printed outside the image area of the master at the printing plate stage. At present, it is pasted on the board and printed along with the original version.

By the way, in the case of four-color printing, Tori et al.'s test pattern is provided on each of the cyan, magenta, yellow, and black printing plates, but when the four colors are printed one on top of the other, In order to prevent the test patterns of each color from overlapping each other, the test patterns must be spaced apart by at least the width of the test patterns. For this reason, the above-mentioned pasting process of the test pattern is sloppy, and although it takes a long time, it is difficult to avoid mistakes that cause the test patterns to overlap on the printed material. The skillful manual work of pasting test patterns using adhesive tape, etc., as described above, is one of the disadvantages of the automation of the entire plate-making process. The challenge for printing this test pattern onto printing plates is to automate the related work.

In view of the above-mentioned current situation, it is an object of the present invention to provide a printing device that can automatically print a test pattern at a predetermined position outside the picture area at the same time as printing an image such as an original film onto a printing plate. The purpose is ζn.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

Since the L-down movement is performed with =, it moves up and down accurately along the axis of the air cylinder +IQ without being biased to the left or right or front or back. The stroke length of the operating loft of the air cylinder wing is set so that the suction cup 09 in the position shown in the figure is in sufficient contact with the upper surface of the transparent glass plate q→ at the top of the base part cI4. . It goes without saying that the connecting plate I21) has a hole in its center to prevent interference with the air cylinder.

Between the pallet standby position and the ejection belt conveyor 4 which is in contact with the pallet and which is provided on the opposite side of the exposure section (2), a frame 6◇ having an adsorption mechanism is connected to the rotary arm 6. A reversing conveyance mechanism fixed in a cantilevered manner is provided. A shaft neck is fixed to each of the left and right rotating arms C+→, and each shaft neck is rotatably supported by a bearing fixed to the frame. A sprocket/sotowheel (B) is fixed to one shaft neck, and this sprocket wheel ■ and a sprocket wheel O fixed to the output shaft of a gear motor Q with a brake fixed to the frame.

The exposed light-sensitive material sheet (indicated by the two-dot chain line) held by (7) is reversed and brought directly above the ejection conveyor, and the seven fLK receiver is arranged to deliver it. In addition, when the frame (B) is located at the pallet standby position or directly above the discharge conveyor (4), the brake is applied when the stopping position of the rotating arm 0) comes into contact with the seven main parts so as to always maintain horizontal superiority. This is regulated by the operation of a limit switch (not shown) that stops the gear motor CI. Although not shown in the figure, the discharge belt conveyor (A) is connected to the automatic dispensing device in the direction of the arrow shown in FIG.

Next, the configuration of the pallet moving mechanism will be explained with reference to FIG.

A connecting part Oa that engages with the pallet moving mechanism (C) is attached to the kite member O2 of the pallets (10A) to (10B). This connecting member Q consists of an arm part fixed to the bracket of the guide member 0, and a roller using a ball bearing fixed to the bent end of the arm part. The pallet moving mechanism is horizontally fixed to the frame (parallel to the frame σ7), and is slidable to the guide vibrator Q (the engaged guide block is connected to the support plate (c)). is fixed fL5. This support plate is rotatably supported via a 7' ball bearing housed in a bracket attached to the upper and lower parts of camphor, and this threaded rod (screwed with The connecting nut portion, which has been treated to prevent rotation, is connected to the air cylinder υ (see Fig. 2), which is fixed to the frame at both ends, and its operating rod G spring, and is connected to the support plate. The main part is made up of the connecting block information fixed at -.The upper end shaft of the threaded rod (G) has a sheave (B) with driven teeth, and the output shaft of the pulse motor has drive teeth. The sheave is fixed in place, and the timing belt is attached to both sheaves) and (b).The pulse motor is connected to the upper guide block 0 through the support frame. → has a constant value of 1.

The connecting nut part i50 has a U-shaped cross section on the side facing the connecting member 04), and is designed to fit into the roller (4]).

The transparent glass plate 0 in the exposure section (b) → The photosensitive material sheet that was placed on the original plate set above, is further spread over it with a rubber sheet, and the residual air between them is vacuum-sucked ζ
In step 9, the original plate and the photosensitive material sheet were vacuum-adhered to the glass plate QFil. For that purpose, a rubber sheet carrier...
are well prepared.

The rubber sheet carrier... is a rubber sheet whose width is slightly wider than 7t1 of the glass plate θυ, wound into a hollow @I in the shape of a hoop, and whose end is fixed to a frame, and which rotates freely to slide vertically. The presser roll, on which the shaft is supported, runs along the rail Ic,! f1. It is held by a pair of left and right support plates, one of which is connected at its lower end to an endless chain driven by a motor. Therefore, when the endless chain is run in the direction of the arrow, the rubber sheet carrier ←1 moves in the direction of the arrow while paying out the rubber sheet, and the presser roll that follows the Due to the action of the 4N cam that fuses the resoturbine at a position that is too far forward, it descends due to its own weight and rolls while suppressing the rubber sheet.The endless chain is made to run in the opposite direction to the above. When the rubber sheet is built into the hollow shaft, the torque acting on the spring from the spring is automatically drawn in, and the glass plate is pulled from the lO. It has become.

At the center of the bottom of the exposure section Q'4, a light source, for example, an instant-light mercury lamp (metal halide lamp) that emits strong ultraviolet light, is installed in the reflection chamber. . In part 1-, the exposure part (14) has an exhaust fan installed on its outer wall to exhaust the hot air inside.
The vacuum pump for vacuum sealing of the original plate and photosensitive material sheet described above is a compressor that supplies compressed air to the air cylinder 09, ψυ, etc.

The structure of each mechanism for printing the printing plates described above has already been filed by the present applicant as Japanese Patent Application No. 57-38734.

Next, the structure of a mechanism for printing a test pattern at a predetermined position outside the picture area of the printing plate will be explained with reference to FIGS. 5 to 11.

If the left and right air cylinders are driven to the Q position and the operating lofts are retracted, the holding film will be
They will each be positioned at the R position.

Next, the operation of this device will be explained.

The original plate is placed on the original plate pallet 0/Ob as shown in Figure 6.
Plant it on the pallet through the reference punch hole drilled in the hole.
The resistor bins are fitted together, and operation 1 is indicated by the arrow.
Viewed from 11i, right end a
The sheets are stacked from above in the order of use, while the photosensitive sheets, such as plate sheets, are separated into sheets of different sizes, such as A1, B2, J, and A2, in the same manner as above. The register pin is fitted into the nine bunch holes, and the barre for the photosensitive material sheet) (10c), (jODll(1['l")
It is assumed that it is stored under the eaves. Let's take as an example the case of printing on an A2 size plate material sheet.

1. Pull out the original plate pallet (10B) in the standby position to the 12th drawer position using the pallet transfer mechanism.

To do this, rotate the connecting nut part (G) shown by the two-dot chain line that is engaged with the pallet (1 [IA) + 7) connecting member (1ψ) in Fig. 4 by rotating the pulse motor in a prescribed direction by a prescribed number of pulses. , lower it along the threaded rod, and engage it with the middle of the connecting member a of the barre and bottom (10B).

Next, the air cylinder φD is operated to push out the operating rod σ, and the pallet (10B) is pulled out to the pull-out position by moving the machine 10h4Iω along the guide pipe 0→. This positioning is performed using Palette) (I D
This is done by the frame E) coming into contact with a stopper (not shown).

In this case, the guide member o3. o: Rail αV attached to i
When there is a slight gap between the rail αυ and the guide roller that rolls in contact with +Uil tfi, a small meandering occurs, which causes the pallet (10By) register pin position to be out of alignment.

In order to prevent this deviation, either pallet (10A
) to (10K), a through shaft (C) with a pinion (a) fixed to each end is rotatably mounted on the side frame with as little bearing clearance as possible, and the pinion (a) is attached to the top of the outside of the rail 0η. Rack with 7″L width (b)
They are designed to mesh in phase with each other.

An A2 size original plate is taken out by the carrier CAQ from the ballet (IOB) which has been drawn out accurately to the drawing position. In this case, as for suction # (c), as shown in Figure 3, the one located at the left end is set so that it does not operate in advance.
As for the suction cup (E), its holding position should be adjusted to match A2 size. While releasing the compressed air inside the air cylinder 01 as described above, move the movable plate (c)
Let it fall naturally at an appropriate speed, and attach the suction cups (c) and (c).
is brought into contact with the original plate (A2) and adsorbed thereon. Then, by supplying compressed air to the air cylinder and retracting the actuating rod, the original plate (A2) attracted to the suction cups (C) and (E) is held as shown by the two-dot chain line.

Next, move the pallet (10B) to the pallet moving mechanism GIFJ.
After returning to the standby position in the opposite way to the above, release the compressed air inside the air cylinder (I),
As mentioned above, lower the movable plate (E) and remove the original plate (A2).
Set it on the transparent glass plate Qυ, and then
), and move the movable Itabe with the same air cylinder as above (
It is restored by the operation of step 19.

In this case, the punch holes in the original plate (A2) are positioned directly above each of the register pins inserted in the glass plate αυ, so the original plate (A2) is set accurately. .

However, just to be on the safe side, when the resistor pins are slightly inserted into the punch holes of both the original plate and plate sheet, stop releasing the compressed air from the air cylinder qO, temporarily stop the descent, and check. It is better to do so.

Next, an A2 size plate material sheet is set on the original plate, but before that, a test pattern film (2 ) Set it on the JJX board.

In ``L'', the test pattern film (b) is attached with the pattern facing up, and the holding film (101) is moved from the standby position C) to the overlapping position on the A2 size original plate). , left and right air cylinders (109),
(109) are moved by traverse in the X-X direction by driving both of them, and held at this position.

After doing this, the pallet (IOE) in which the A2 size plate material sheets are stored is moved to the pallet (10A).The pallet moving mechanism (
C) and by having the carrier OQ perform this process, it is accurately superimposed on the original plate (A2) set on the glass plate a$. Then, the rubber sheet is spread over the overlapping original plate and printing plate as described above using a rubber sheet carrier, and vacuum suction is applied to the rubber sheet,
Glass plate (Remove residual air between the plates, and vacuum adhere the original plate and printing plate sheet to the glass plate OFj.

In this case, the test pattern film Cω is placed on the original plate (A2).
and the holding film (1) A slight gap will be created between the original plate (A2) and the rubber sheet along the inside of the overlapping part, and this gap will occur in the blank area, so there is no problem. However, if the films (b) and (101) are made extremely thin, or if a vacuum pump with a large capacity is used, the effect of the gap on vacuum adhesion can be ignored.

Then, a mercury lamp is turned on and the mercury lamp is turned on for a predetermined period of time, e.g.
Exposure is performed for about seconds to complete printing.

The rubber sheet carrier is returned to the position shown in FIG. 1 and the rubber sheet is removed, the vacuum being broken beforehand. Next, after returning the holding film (101) to the standby position (P), the movable plate (G) of the carrier OQ is lowered, and the exposed plate material sheet is sucked by the suction cups -, @, and removed from the original plate. Peel it off and hold it in the position shown in Figure 1. Then, the air cylinders (not shown) connected to the carts θ of the carrier 00 are fully activated, the carrier Oe is moved to the standby position, the vacuum of the suction cups @, (η is broken, and The exposed plate material sheet that was being held is adsorbed to a suction cup attached to the rotating frame 6υ of the reversing conveyance mechanism (to), and the receiver is transferred.

Next, the frame 6υ is rotated in the direction of the arrow ζ, and the exposed plate material sheet is reversed and brought to the direct hole of the discharge belt conveyor 4, the vacuum of the suction cup (G) is broken, and the plate material sheet is transferred to the belt. The receiver is transferred to a conveyor and discharged in the direction of the arrow shown in FIG. If an automatic developing device is provided connected to the discharge belt conveyor, it is preferable to set the discharge speed to the developing processing speed by nl 1ff3.

In addition, since the plate material sheet was set so that the side coated with the photosensitive agent was in contact with the original plate, when it was turned over and passed to the discharge belt conveyor 4 as described above, the side coated with the emulsion was placed on the upper side. Since the belt does not come into contact with the belt directly, damage during transportation to the developing device can be prevented.

While the exposed plate material sheet is being transferred to the above-mentioned discharge belt conveyor by the reversing conveyance mechanism a,
Return the carrier QQ to the position shown in Figure 1, then lower the movable plate (goods) and place the used original plate on the suction cups (c), (
When the movable plate (A) is attracted by the position shown in FIG.

Next, the used original plate pallet (10A) is pulled out from its standby position h° to the draw-out position by the pallet moving mechanism as described above. Then lower the movable plate section),
Bring the used original plate held by suction cup (A) and 09 into Palekh) (IOA), and suction cup (C).
Break the vacuum in (7) and store it inside.

At the same time as the movable plate (c) is returned to the position shown in FIG. 1, the pallet (IOA) is returned to the standby position by the pallet moving mechanism 14υ.

Test pattern film Q returned to standby position (P)
The holding film (101) H1 to which IjJ is attached is moved by a distance in the direction of the arrow Y in FIG. 7 by simultaneously driving the torque motor 507 and the reversible motor (107R). Here L>lO・-・0), 4X(

When the motor (107R) is moved by a certain length L, that is, the test pattern is moved by a distance L in the Y direction, the motor (107R) stops, and at the same time, the electromagnetic The brake is activated [2. The test pattern is held at the stop position. Next, each of the above operations is performed! The process of printing both the original image and the test pattern onto four printing plates was completed several times. When the holding film (101) to which the test pattern film (b) is attached moves by 4L in the Y direction, the pulley (103R) is rotated in the opposite direction against the torque of the torque motor (107L). Reversible motor (1o7R) All 12 movements L, the test pattern is in the first position if/C, and the holding film (1 (
11) is wound around a pulley (103R) by a length of 4L.

The above is based on the example of printing an A2 size printing plate. As mentioned above, in the step 78 for printing a B2 size printing plate, the holding film (101) is held in the Q position and a four-color printing plate is printed, so each operation is performed in 4 steps as described above.
You can do it repeatedly. When printing a printing plate with a maximum of 6 colors, the condition ←) is not necessarily 6 to 3.

In the above, we have described the case in which printing plates with A2 and B22 glaze sizes are printed using this device. However, if there is a cover to be printed on printing plates of size 1 or larger, the test pattern film ( 9) Holding film (
101) at a predetermined holding position in addition to the above-mentioned Q position and R position, an air cylinder (109),
Instead of (109), a linear drive mechanism whose stroke can be easily adjusted may be used, such as a linear head consisting of a combination of a rack and a pinion.

Also, instead of the holding film (1n1) in this example device, a transparent thin plate ([1) shown in FIG. 12 was used,
and n are moved by a predetermined amount in both the X and Y directions by a combination of appropriate drive mechanisms, and the test pattern is
Orientation-wise baking is also possible.

As is clear from the above description, the printing apparatus according to the present invention can accurately and speedily automatically process all printing of test patterns onto plate materials, including the related work, which was conventionally done manually. This will greatly contribute to saving labor and speeding up the entire plate-making process.
