Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention applies to a photosensitive lithographic printing plate processing apparatus in which a developing tank and a rinsing tank are arranged in order along the conveyance direction of the photosensitive lithographic printing plate. The present invention relates to a photosensitive lithographic printing plate feeding device for feeding printing plates.

[Prior art] Using an automatic developing machine or the like (photosensitive lithographic printing plate processing equipment), a photosensitive lithographic printing plate (the photosensitive layer whose solubility changes upon irradiation with light is an aluminum plate, zinc plate, iron plate, plastic plate, etc.) is processed. When processing a large number of photosensitive lithographic printing plates (one coated on both sides or one side of the support plate as appropriate), a photosensitive lithographic printing plate feeding device connected to an automatic processor is used. often. In this case, the automatic developing machine is equipped with a rinsing tank (washing tank, gum liquid application tank), a drying device, etc. in addition to a developing tank.

For example, a conventional photosensitive planographic printing plate feeding device is such that a plurality of photosensitive planographic printing plates are placed on a mounting table placed on the side of the photosensitive planographic printing plate insertion opening of an automatic processor, and one layer is fed from the outermost layer to the other. The sheets are taken out one by one and sent into the developing tank of an automatic developing machine, where they are sequentially conveyed to the developing tank, rinsing tank, and drying tank, and undergo various processing. As such a photosensitive lithographic printing plate feeding device, Japanese Patent Application No. 1475/1986
It was proposed in Japanese Patent Application No. 61-249423.

[Problems to be Solved by the Invention] However, some photosensitive lithographic printing plates are subjected to only the water washing treatment and the application of a gum solution again after the development treatment has already been completed. In this case, the conventional photosensitive lithographic printing plate feeding apparatus described above supplies the photosensitive lithographic printing plate into the developing tank, and therefore cannot directly feed the plate to the rinsing tank (water washing treatment, gum solution coating).

Therefore, the operator must manually feed the rinsing tank into the rinsing tank, which is a complicated task.

In consideration of the above facts, the present invention provides a photosensitive planographic printing plate that can be directly fed into a rinsing tank without having to be inserted into a developing tank when the photosensitive planographic printing plate is fed into the photosensitive planographic printing plate processing apparatus again. The purpose is to provide equipment.

[Means for Solving the Problems] In the present invention, a photosensitive planographic printing plate is transferred to a photosensitive planographic printing plate processing device in which a developing tank and a rinsing treatment tank are arranged in order along the conveying direction of the photosensitive planographic printing plate. A photosensitive lithographic printing plate feeding device for feeding the photosensitive lithographic printing plate, which includes a mounting table on which the photosensitive lithographic printing plate is vertically placed, and an outermost layer of the photosensitive lithographic printing plate placed on the mounting table from the upper end. A feeding means for sending the photosensitive planographic printing plate to the photosensitive planographic printing plate processing device, and a conveyance path of the photosensitive planographic printing plate sent out by the sending feeding device are changed to either a developing tank or a rinsing treatment tank of the photosensitive planographic printing plate processing device. The apparatus includes a conveyance path changing means for guiding the photosensitive planographic printing plate.

[Function] In the present invention having the above configuration, for example, when a photosensitive lithographic printing plate that has been exposed to light and has not been developed is supplied to a photosensitive lithographic printing plate processing apparatus, the photosensitive lithographic printing plate is placed vertically on a mounting table. The outermost layer of the photosensitive lithographic printing plate is sent out by the feeding means and sent into the developing tank of the photosensitive lithographic printing plate processing apparatus, and after being developed, it is placed in the rinsing processing tank. sent to and processed.

On the other hand, a photosensitive lithographic printing plate that has already been subjected to development processing and only undergoes rinsing treatment again is placed vertically on a mounting table in the same way as the above-mentioned photosensitive lithographic printing plate, and the outermost layer of the photosensitive lithographic printing plate is is sent toward a photosensitive lithographic printing plate processing device by a feeding pile means. In this case, since the photosensitive lithographic printing plate has already undergone development processing and only undergoes rinsing processing, its transport path is changed by the transport path changing means and the plate is sent directly into the rinsing tank.

In this way, in the present invention, the transport path can be changed depending on the type of photosensitive planographic printing plate, so when the photosensitive planographic printing plate is inserted into the photosensitive planographic printing plate processing apparatus again, it can be inserted into the developer tank. It can be inserted directly into the rinsing tank. This facilitates the operation when reinserting the photosensitive planographic printing plate into the photosensitive planographic printing plate processing apparatus.

Support plates 48 are attached to the plurality of support shafts 44 with screws 50, and a plurality of notches 52 are formed in these support plates 48 to allow a part of the guide ring 46 to protrude toward the mounting table 14 side. has been done. This is designed to prevent the PS plate 16 supported by the guide ring 46 from being accidentally pulled out to the left side of the guide ring 46 in FIG.

A rotary shaft 54 is supported parallel to the side plates 28 and 30 between the second and third support shafts 44 from the top of the plurality of support shafts 44, and a sprocket wheel 56 is fixed. These sprocket wheels 56 are arranged above the inner guide plate 42, and an inner chino 60 is wound around each sprocket foil 56. This inner chino 60 is the support shaft 3
The other part is wrapped around a sprocket foil 62 fixed to the sprocket wheel 8, and is adapted to move along the surface of the inner guide plate 42 between these sprocket wheels 56 and 62.

This inner chino 60 has a hook 64, which is a mounting table, fixed at its longitudinal end. This hook 64 has a single-shaped side surface as shown in FIG. The uppermost PS plate 1 of the plurality of PS plates 16 installed on the mounting table 14
6 is accommodated at the lower end. Also, the rotation axis 5
4 is attached with a motor 66, which can rotate the rotating shaft 54 clockwise and counterclockwise in FIG. Therefore, by rotating the sprocket wheel 62 counterclockwise in FIG.
The plate can be lifted and guided by the rotation of the guide ring 46 and sent toward the photosensitive planographic printing plate processing apparatus 12.

Movement of the hook 64 is restricted by a limit switch 58A attached near the sprocket wheel 62 and an upper limit switch 58B attached near the sprocket wheel 56.

As shown in FIG. 3, the support shaft 34) sprocket foil 70, the support shaft 38 and the sprocket foil 72 are further connected to the support shaft 36 between the side plates 28, 30 and the inner guide plate 42 when viewed from the front. Sprocket foils 74 are attached and outer chinos 76 are wrapped around each. These outer chinos 76 can be rotated clockwise and counterclockwise in FIG. 2 by receiving the driving force of a motor 78 connected to the support shaft 38.

These outer chinos 76 are guided by an outer guide plate 80 disposed between the support shaft 34 and the support shaft 38. These outer guide plates 80 extend above the support shaft 38 in parallel with the inner chino 60, and
The upper portion thereof is bent into an arc shape, and its extension line forms a tangent to the pitch circle of the sprocket wheel 70.

Further, a plurality of connecting shafts 82 are extended between the outer teeth 276, and guide rings 84 similar to the guide rings 46 are supported at equal intervals in the intermediate portions of these connecting shafts 82.

Therefore, when the lower end of the PS plate 16 is mounted on the hook 64 and rotated counterclockwise in FIG. It is designed to be separated and transferred onto the guide ring 46.

Note that, as shown in FIG. 7, a notch 85 is formed in a part of the hook 64 through which a guide ring 84 passes.

In order to control the stroke of these outer chains 76, an upper limit switch 8 is arranged near the sprocket wheel 70, and a lower limit switch 88 is arranged near the sprocket wheel 72.

As shown in FIG. 6, a stay 67 is attached to the leading edge and the next connecting shaft 82 attached to the outer chino 76 that moves counterclockwise in FIG.
A photosensitive plate detection switch 68 is attached to the plate. The photosensitive plate detection switch 68 is a reflective optical sensor, and is capable of detecting the leading edge of the PS plate 16 that has been transferred from the mounting table 14 to the separating support section 18.

Adjacent to the sprocket wheel 70, a pair of movable feed rollers 90, 92 forming part of the conveyance path changing means are arranged. The feed rollers 90 and 92 feed the PS plate 16 from the feeding device 10 to the photosensitive planographic printing plate processing device 1.
It is for sending to 2. The movable feed rollers 90, 92 are supported by the side plates 28, 30, and are pivoted to a pair of side plates 94 that are movable in the vertical direction. This side plate 94 is moved to the side plate 2 by a driving force of a driving means (not shown).
It is designed to move up and down along the side of 8.30.

A motor 96 is fixed to the side plate 94, and this motor 96 is connected to the feed roller 90 by a connecting means (not shown).
．． The feed roller 90.92 is connected to the rotating shaft of 92.
It is designed to rotate.

A movable guide 98 is attached to the side plate 94 and is driven by a drive means (not shown). The movable guide 98 is in a vertical state when the feed rollers 90, 92 are located at the bottom, and is projected horizontally when the feed rollers 90, 92 are located at the top.

Further, in the photosensitive lithographic printing plate processing device 12, a developing tank 11 is provided.
A washing tank 13 and a desensitization treatment tank 15 are arranged in sequence along the conveyance direction of 16 of the 28 plates. When the PS plate 16 sent out from the supply device 10 is sent into the developing tank 11, the feed flow 90, 92 is located at the lower part 1'. Further, when the PS plate 16 is directly fed into the washing tank 13, the feed rollers 90 and 92 are positioned at the upper part.

In addition, the transport path switching plate 1 is located at the upper part between the side plates 28 and 30.
00 are arranged along the width direction of the support plate 48. One end of this conveyance path switching plate 100 is attached to a shaft 102 whose both ends are rotatably supported by side plates 28, 30. The driving force of a driving means (not shown) is transmitted to the shaft 102, and the shaft 102 is moved from the position where it abuts on the support plate 48, as shown by the solid line in FIG. It is designed to oscillate.

A moving means 112 is provided in the lower part between the side plates 28, 30. A pair of suction cups 114 and 116 are arranged on this moving means 112 as shown in FIG.
It is for adsorption of 6.

These suction cups 114 and 116 are attached to the tip of the support shaft 118, and are configured to receive negative pressure from a negative pressure source (not shown) so that they can suction the PS plate 16 using the negative pressure.

The support shaft 118 has an intermediate portion passing through the support plate 120, a tip portion thereof passing through the support plate 122, and these support plates 120.1
22 and can be slid.

An E IJ song 24 is attached to the middle portion of the support shaft 118 , and a compression coil spring 126 is interposed between the E ring 124 and the support plate 122 . For this reason, these suction cups 114 and 116 are supported by the support plates 120 and 122, but the support plates 120 and 122 are pushed out in the direction of the mounting table 14, and the suction cups 114 and 116 are pressed against the 23rd plate 16. Then, the support plates 120 and 122 that move further compress the compression coil spring 126 and use the elastic force of the compression coil spring 126 to move the suction cups 114 and 116 to the 23rd plate 16.
It's like it's being pushed towards you.

The pressing rod 130, whose tip end and middle portion are fixed to support plates 120 and 122, respectively, is slidable while being guided by a bearing 134 attached to a base plate 132.

A long link 138 is attached to the middle part of the support plate 122 with a pin 136.
One end is pivoted. The other end of this long link 138 is pivotally supported by a pin 140 to one end of a short link 142.

Further, the other end of the short link 142 is fixed to the rotating shaft 144,
This rotating shaft 144 is connected to an output shaft 148 of a motor 146.

Therefore, the rotation of the motor 146 is transmitted as the rotational force of the short link 142, and the long link 138 receives this rotational force via the pin 140.
A reciprocating slider crank mechanism is configured to reciprocate the slider 22.

Here, the axial center of the rotating shaft 144 is arranged offset from the movement extension line of the reciprocating pin 136, thereby forming a rapid feed mechanism. In other words, the forward stroke and return stroke of the reciprocating movement of the pin 136 are performed by the short link 142.
This corresponds to the rotation angles θ and θ2. Therefore, the rotational speed of the rotating shaft 144, which rotates at a constant speed, is such that the rotation angle θ1 corresponds to the forward stroke of the suction cups 114 and 116, and the angle θ2, which is larger than this, corresponds to the return stroke, so the suction cup 114.116 quickly places the mounting table 1
4 approaches and adsorbs 23rd version 16, and adsorbs 23rd version 1
6 in the direction of the hook 64 at a slower speed than this.

These suction cups 114 and 116 move the 23rd version 16 above the hook 64 after adsorbing the 23rd version 16, and then the negative pressure is released and the lower end of the 23rd version 16 is moved to the hook 64. It has become. In this case, mounting table 1
Of the 23 plates 16 mounted on the 4, only the top 23 plate 16 is suctioned by the suction cup 114, 116, but if this top layer 23 plate 16 and the next layer 23 plate 16 are in close contact with each other, , carelessly the next layer 23rd version 16 is the top layer 23rd version 16
It may be pulled out while still attached to the

For this reason, after suctioning the 23rd plate 16, the suction cups 114 and 116 move slightly to the left in FIG. It is preferable to take care that the photosensitive plate of the next layer is separated from the uppermost layer 23 plate 16 by its own weight and slides down, remaining on the support piece 24.

Furthermore, for this purpose, it is preferable to stick a tape 154 provided with a plurality of small protrusions onto the support piece 24 toward the end face of the 23rd plate 16. This tape 154 can be made of a material such as Velcro tape (trade name) having a plurality of small protrusions protruding from one side thereof. With this, suction cup 1
14. A movement resistance force is applied to the lower end surface of the 23rd plate 16 that is attracted and moved by the 116, and the 23rd plate 16 of the next layer, which is not receiving the suction force and moves inadvertently in close contact with the 23rd plate 16 of the top layer.
It can be separated from

Furthermore, as is clear from Fig. 3, the suction cups 114 and 116
The distance between them is 1/ of the width of the separation holding part 18 and the mounting table 14.
It has dimensions of 2 or less, and there are multiple types of 23 that are used.
Among the plates 16, this corresponds to the 23rd plate 16 with the minimum width dimension. In order to suction 23 plates 16 with a large width dimension, it is preferable to provide a larger number of suction cups or to widen the interval between suction cups 114 and 116.
When adsorbing the 3rd edition 16, the 23rd edition 16 with the widest width of the next layer
will also be adsorbed, so according to the minimum width dimension,
The spacing between the suction cups 114 and 116 is fixed.

Further, as shown in FIG. 5, the tape 154 is attached to the suction cup 1.
14 and 116 is preferably attached to the support piece 24. If the suction cups 114 and 1160 are provided at a position away from the space between the suction cups 114 and 1160, resistance will be given to the movement of the PS plate 16 when the suction cups 114 and 116 move by suction, and the deflection of both ends of the PS plate 160 in plan view will increase. This causes the end portion with large bending to not enter into the hook 64.

Next, the operation of this embodiment will be explained.

As shown in FIG. 2, in the initial state, the hook 64 is stopped on the side of the sprocket wheel 62 and facing the mounting table 14, and the outer chino 76 has a guide ring 84 at the forefront of the hook 64. It is arranged horizontally.

Also, feed rollers 90 and 92, conveyance path switching plate 1
00 is placed at the position shown by the dashed dotted line in Figure 2.

Here, a plurality of 23 plates 16 after exposure are stacked and mounted vertically on the mounting table 14.

This 23rd plate 16 has only been exposed.

In the moving means 112, suction cups 114 and 116 protrude rightward in FIG. 2 by driving rotation of the motor 146 at an angle θ1, and suction the vicinity of the lower end of the top layer 23 plate 16 on the mounting table 14. After suction, the motor rotates by an angle θ2 and the suction cup 114
．． 116 returns to the left in FIG. 2, releasing the negative pressure above the hook 64. As a result, the top layer 23 version 1
6 - its lower end falls into the hook 64.

The motor 78 is now driven, and the outer chino 76 is rotated counterclockwise in FIG. For this reason, the guide ring 84 of the uppermost layer 23 plate 16 whose lower end is housed in the hook 64 is moved upward by the guide ring 84 sequentially moving up the photosensitive surface (the right surface in FIG. 2), so that the middle part of the 23 plate 16 is lowered. From the top to the top, it is gradually separated from the mounting table 14 and moved to the top of the separating support section 18, so that the anti-photosensitive surface side touches the plurality of guide rings 46.

In this case, since the lower end of the 23rd edition 16 is housed in the stationary hook 64, the 23rd edition 16 can be stably supported even when the guide ring 84 is raised. This hook 6
If 4 is also attached to the outer chain, that is, if the inner chain 60 is omitted, the hook 6
4 corresponds to the lower end of the 23rd plate 16, the suction cup 114
．． 116 must hold the 23rd edition 16, so the holding force of the suction cup must be increased.

When the photosensitive plate detection switch 68 guided by the guide ring 84 at the tip rises along the photosensitive surface side of the 23rd plate 16 and detects the upper end of the 23rd plate 16, the motor 66 is also driven and the inner chino 60 moves to the outer chino 76. and the second at the same speed.
Rotate counterclockwise. This causes the hook 64 to rise and lift up the 23rd plate 16.

Therefore, the guide ring 84 at the tip holds the upper end of the 23rd plate 16 between it and the guide ring 46, and the outer guide portion 84
The upper end of the 23rd plate 16 is gradually bent in the horizontal direction along the 23rd plate 16 and sent out between the nipping rollers 92 and 94.

In this case, the motor 78 and the motor 66 rapidly raise the 23rd plate 16, and the tip of the 23rd plate 16 moves to the clamping roller 92.
When the guide ring 84 at the tip is detected by the upper limit switch 86 in a state immediately before the guide ring 94, it is preferable to rotate at a low speed, thereby shortening the working time.

This low speed is slower than the rotational speed of the holding rollers 92, 94 so that the leading end of the 23rd printing plate 16 can be smoothly fed.

When the tip of the 23rd plate 16 is clamped by the clamping rollers 92 and 94, the motor 66 rotates in reverse, rotates the inner chino 60 counterclockwise in Figure 2, and stops the hook 64 as shown in Figure 2. do. The reverse rotation of the motor 66 may be started after a predetermined time delay after the upper limit switch 86 detects the guide ring 84. On the other hand, the outer chain 76 is stopped until the rear end of the sent 23rd plate 16 passes near the sprocket wheel 56, and the rear end of the 23rd plate 16 becomes straight due to its rigidity, and the next layer on the mounting table 14 is This prevents the problem of contacting the 23rd edition of 16.

At this point, the outer chino 76 is reversed, and the guide ring 84 at its tip returns to the state shown in FIG. 2 to prepare for adsorption of the next layer of 23 plates 16. Stopping and reversing of the outer chain 76 may be started after a predetermined time delay after the upper limit switch 86 detects the guide ring 84.

In this way, since the hook 64 and the guide ring 84 are separately driven by the inner chino 60 and the outer chino 76, it is possible to drive these quickly and shorten the work cycle. That is, the outer chino 76 and the inner chino 60 are configured as one chino, to which the hook 64 and the connecting shaft 8 are connected.
2. If the guide ring 84 is installed together, the guide ring 84 at the tip should be used when feeding a small PS plate 16.
Since the small-sized PS plate 16 has to be completely removed from the nipping rollers 92 and 94, the ceno can be returned to its original position, which slows down the work cycle.

In order to make it easier to load the PS plate 16 onto the mounting table 14, as shown in FIG. A rotation axis may also be provided.

Next, a case will be described in which the PS plate 16, which has already been subjected to development processing and is subjected to only water washing processing and desensitization processing again, is sent to the photosensitive lithographic printing plate processing apparatus 12.

In this case, the feed rollers 90, 92 move upward, and the conveyance path switching plate 100 is positioned at the position shown by the solid line in FIG. Furthermore, a movable guide 98 is projected along the horizontal direction.

In this state, the PS plate 16 placed on the mounting table 14 is moved by the moving means 112 and placed on the hook 64. Thereafter, the motor 66 is activated and the hook 64 is raised to raise the PS plate 16.

The PS plate 16 that has risen is guided by the conveyance path switching plate 100, further rises, and is inserted between the feed rollers 90 and 92 located at the top. Feed roller 90.
The PS plate 16 inserted between the feed rollers 9
0.92 from the supply device 10, guided by the movable guide 98, and directly inserted into the washing tank 11.

Thereby, when processing the developed PS plate 16 again, it can be directly inserted into the washing tank 13 without performing the development process.

The PS plate 16 inserted into the water washing tank 13 is transported to a desensitizing treatment device 15 for treatment.

In this embodiment, the feed rollers 90 and 92 are moved up and down, but the feed rollers 90 and 92 may be provided at the top and bottom, respectively, and the conveyance path of the PS plate 16 may be changed using only the conveyance path switching plate 100.
