Abstract

PURPOSE:To simplify the structure, eliminate the dispersion of the feed quantity of a photosensitive material between multiple magazine loading sections, and facilitate the control in the post-process when multiple magazine loading sections are provided. CONSTITUTION:Separately operable electromagnetic clutches 170, 171 are provided between drive rollers 138, 139 and a motor 188. When a lower magazine loading unit 124 is selected, the electromagnetic clutch 170 is excited, and the driving force of the motor 188 is transmitted to the drive roller 138. The coil of the electromagnetic clutch 171 is not excited in an unselected upper magazine loading unit 126, and the drive roller 139 is not rotated when the motor 188 is driven. Since the electromagnetic clutches 170, 171 are provided respectively, drive rollers 138, 139 can be independently driven by the single motor 188, the structure is simplified, and the conveyance error generated when drive sources are independently provided is eliminated.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate inspection device. More specifically, the present invention relates to an inspection plate creation device that creates an inspection plate used for checking the quality of color printed matter.

0002

[Prior Art] When a printing machine prints a large amount of color printing, for example, color advertisements (so-called insert advertisements) attached to newspapers, etc., a plate inspection device (color proof production I try to check this in advance before actually printing using the printer. The inspection plate making device includes a surface plate section where the photosensitive material and the original film which has been subjected to decomposition exposure and development processing are conveyed and positioned, and an exposure section which is arranged correspondingly on the surface plate and exposes the image of the document film onto the photosensitive material. a processor section that develops the exposed photosensitive material; and a transfer section that transfers the photosensitive material from the surface plate section to the processor section. A plurality of original films are prepared for each color separation component, and one set is made up of a plurality of original films. are exposed sequentially. The exposed photosensitive material is conveyed from the platen section to the processor section via the delivery section, where it is subjected to development, bleach-fixing, washing, and drying processing. This processed photosensitive material allows for a preliminary check before actual printing. As a result, if there is a problem with the color, image position, character error, etc. of the photosensitive material, for example, the original film can be corrected before being printed in large quantities by the printing machine.

There are usually three types of photosensitive materials used in this plate inspection device: positive paper, negative paper, and positive film, and the widths of these photosensitive materials are 610 mm, 485 mm, and 357 mm, respectively. There are several types of photosensitive materials, and one of nine types of photosensitive materials is used in the plate inspection device. These photosensitive materials are of a magazine type, in which a long photosensitive material is wound into a roll and stored. Further, this magazine is positioned in advance and loaded into the magazine loading section of the plate inspection and production device. Furthermore, since the photosensitive materials used differ depending on the original film, the plate inspection device is loaded with a magazine containing the photosensitive material corresponding to the original film.

[0004] Generally, a plate inspection device is used with one magazine loaded therein. However, this magazine is heavy because it contains a long photosensitive material rolled into a roll and stored in a light-shielded manner, and the work of replacing the magazine reduces the work efficiency of plate inspection work.

[0005] In order to solve this problem, a magazine loading section capable of loading two magazines is provided in the inspection plate making device.
A method for reducing magazine exchange work during plate inspection is being considered (see Japanese Patent Laid-Open No. 3-107835 as an example).

[0006] In this plate inspection device, when a large number of the same photosensitive materials are used, the same photosensitive materials can be loaded into two loading sections, and when one is used up, the other can be used. Further, two types of frequently used photosensitive materials are loaded in each loading section in advance, and an appropriate photosensitive material is drawn out according to the original film.

[0007]

However, the conventional structure described above requires an independent drive system for each magazine loading section, resulting in a complicated structure.

Furthermore, when sending out a photosensitive material, an encoder is usually attached to a motor serving as a driving source in order to detect the length of the material, but the number of encoders corresponding to each motor is required. Furthermore, if there is a detection error between these encoders, the amount of feed of the photosensitive material between the two conveyance systems will vary, which will complicate control in subsequent processes.

In consideration of the above facts, the present invention simplifies the structure when a plurality of magazine loading sections are provided, eliminates variations in the feed amount of photosensitive material between the plurality of magazine loading sections, and improves the speed of post-processing. The purpose is to obtain a plate inspection device that can be easily controlled.

[Means for Solving the Problems] The invention as set forth in claim 1 is a method for extracting a long photosensitive material stored in a magazine, exposing an image recorded on a document film on a surface plate, and exposing the image recorded on a document film after exposure. A plate inspection device that performs a series of development processes on a photosensitive material in a processor section, comprising at least two magazine accommodating sections for accommodating the magazines, and a device for pulling out the magazines from the magazines accommodated in the at least two magazine accommodating sections. A conveyance roller is provided on each conveyance path in order to wrap around the photosensitive material and convey it to the same conveyance path through individual conveyance paths, and a single conveyance roller provided corresponding to the conveyance roller provided on each of the conveyance paths. a rotating member that rotates by receiving a driving force from a drive source; and a clutch means provided between the rotating member and the rotating shaft of the conveying roller to engage and disengage the rotating member and the rotating shaft of the conveying roller. , and control means for selectively operating the clutch means.

[0011]

[Function] According to the invention described in claim 1, each of the two magazine accommodating sections is provided with a conveyance roller, and the photosensitive material is wound around the conveyance roller, so that the photosensitive material is passed through an individual conveyance path. After that, it is transported to the same transport path.

[0012] Here, when extracting the necessary photosensitive material,
The control means operates the clutch means to engage the rotary member with the rotating shaft of the conveyance roller of the magazine storage section in which the magazines of necessary photosensitive materials are stored. In addition, in other clutch means, the rotation shaft of the conveyance roller and the rotation member are disengaged from each other.

[0013] As a result, the conveying roller can be selectively rotated by a single driving source, which simplifies the structure. Further, since there is a single driving source, there is no difference in the amount of conveyance of the photosensitive material, and control in subsequent processes is simplified.

The film loading section 36 is arranged above the ceiling member 58 of the processor section 34. For this reason, the height of the film loading section 36 is relatively low, and is approximately the height of the worker's waist. Film loading section 36
is covered by a large lid 24. The large lid 24 is attached via a hinge. For this reason, the large lid 24
is opened by rotating around the hinge. Further, this large lid 24 is provided with a rectangular hole 60, and a small lid 62 is attached via a hinge. As a result, the small lid 62 is opened by grasping the handle 64 and rotating it from the front side to the rear side in FIG. 3 of the plate inspection device 10. This small lid 62 is opened when loading the original film 16 into the film loading section 36. A locking mechanism is attached to the periphery of the rectangular hole 60, so that the small lid 62 can be locked in a closed state.

The film loading section 36 has an overlay sheet 66 (see FIG. 1) on which the original film 16 is placed.
A frame-shaped support base 68 to which a support base 68 is attached is provided, and is movable back and forth between the support base 68 and the surface plate portion 28 . That is, the film loading section 36 and the exposure section 30 are communicated through a rectangular hole 70. This rectangular hole 70 is opened when the support base 68 moves, but is shielded at other times.

The support base 68 transports the original film 16 loaded in the film loading section 36 to the surface plate section 28.
The image recorded on the original film 16 is transferred to the photosensitive material 14.
It has the role of exposing the film to light and returning it to the film loading section 36 again after the exposure is completed. The plate inspection production device 10 of this embodiment prepares the layout of the manuscript film 16 before creating the actual printing plate using each manuscript film 16 color-separated into Y, M, C, and BK (black) plates. This device is used to check whether there are any errors in the original film, whether there are any differences in color, whether there are any errors in characters, etc.

, R (red), and BK (shade) are used for exposure.

As shown in FIG. 3, a control device 38 is disposed below the surface plate section 28, and controls the conveyance of the photosensitive material 14, the drive control of the support base 68 of the film loading section 36, and the control of the exposure section 30. Exposure control and control of processing liquid temperature, drying temperature, conveyance speed, etc. of the processor section 34 is performed.

The structure of the magazine loading section 100 will be explained in detail below. As shown in FIGS. 1 to 3, a magazine loading section 100 is provided protruding from the left end portion of the plate inspection production device 10 (on the left side of the page shown in FIG. 3). As shown in FIG. 5, the side plate 11 at the left end of the plate inspection making device 10 is bent at an intermediate portion in the vertical direction, and an inclined surface 11A is formed upward from the intermediate portion, and an inclined surface 11A is formed from the intermediate portion downward. A vertical surface 11B is formed which is substantially perpendicular to the floor surface. Note that the inclined surface 11A is inclined at an acute angle θ with respect to the vertical line L, and in the plate inspection device 10 according to the present embodiment,
Although this angle θ is approximately 20°, it is not limited to this. Magazine loading units 124 and 126 are installed inside the inclined surface 11A and the vertical surface 11B, respectively.

The magazine loading units 124 and 126 are both substantially box-shaped and have the same shape. The surfaces of these magazine loading units 124 and 126 on the side plate 11 side are open over almost the entire surface, and correspondingly, the inclined surface 11A and the vertical surface 11B are also opened.

As shown in FIGS. 3 and 5, the inclined surface 1
Opening/closing lids 120 and 122 are attached to these openings of 1, respectively. On the surface of these opening/closing lids 120, 122 opposite to the magazine loading units 124, 126,
A handle 130 is provided, and a hinge 128 is provided at the lower end.
is installed. The opening/closing lids 120 and 122 have handles 1
30 and rotated around the hinge 128, thereby opening and closing the magazine loading units 124 and 126.

Further, light shielding means such as a sponge is provided on the inner periphery of the opening/closing lids 120, 122, so that when the opening/closing lids 120, 122 are closed, the interior of the magazine loading units 124, 126 is securely closed. It is designed to be shielded from light. Note that the opening/closing lids 120, 122 are normally locked in the closed state by a locking mechanism (not shown), and when opening/closing lids 120, 122, this lock is released.

A limit switch 107 is attached to the opening periphery of the inclined surface 11 that the opening/closing lids 120, 122 come into contact with when they are closed.
The open/closed state of the limit switch 107 can be recognized by the on/off state of the limit switch 107.

At the bottom of each of the magazine loading units 124 and 126 is a magazine 10 containing the photosensitive material 14.
2 is accommodated. These magazines 102 store the photosensitive material 14 used in the plate inspection device 10 in a rolled form, and as shown in FIG.
It has a long box shape along the width direction of 4. Magazine 1
An outlet 108 for drawing out the photosensitive material 14 from inside is formed along the width direction on the upper surface of the photosensitive material 02 (the upper surface of the paper in FIG. 4). The outlet 108 communicates with the inside of the magazine 102, but has a structure that prevents light from entering.

A light reflecting sheet 110 is attached to a surface of the magazine 102 that corresponds to the back wall surface 104 of the magazine loading units 124 and 126. A maximum of four light-reflecting sheets 110 are pasted, and three types of photosensitive materials, such as positive paper, negative paper, or positive film, and three types of width sizes of the photosensitive materials are distinguished by the presence or absence of the light-reflecting sheets 110. .

On the other hand, the light reflecting sheet 11 of the magazine 102
Corresponding to 0, a photoelectric sensor 114 is disposed inside the plate inspection device 10, and the presence or absence of the light reflecting sheet 110 is converted into an electrical signal and the electrical signal is supplied to the control device 38.

Above the magazine 102, that is, above each of the magazine loading units 124 and 126, there are a pull-out guide 134, a lower pair of rollers 136, and an upper pair of rollers 13.
7 and a cutter 116 are arranged.

[0033] Below, the magazine loading units 124, 12
6 has a similar internal structure, so we will mainly explain the inside of the magazine loading unit 124 (note that the numbers in parentheses indicate the numbers corresponding to the film loading unit 126).The insertion guide 134 has an arcuate middle section. The conveyance path of the photosensitive material 14 pulled out from the magazine 102 is turned at right angles and directed toward the inside of the plate inspection device 10 . A lower roller pair 136 (upper roller pair 137) is provided at the bent portion of the insertion guide 134. The lower rollers of the lower roller pair 136 (upper roller pair 137) are drive rollers 138 (139).

Further, the upper roller of the lower roller pair 136 (upper roller pair 137) is a presser roller 140 (14
1), and a nip force is applied between the drive roller 138 (139) and the photosensitive material 14 to be held therebetween.

As shown in FIGS. 5 and 6, a pair of L-shaped brackets 142 are provided at both ends of the press roller 140 (141) in the axial direction. The middle portion of each of the pair of brackets 142 is connected to the drive roller 138 (
139), whose axes are parallel to each other, and are fixed to a shaft 144 that spans and is supported by the side plate 106. A notch 142A is formed at one end of these brackets 142, and the shaft 14 of the presser roller 140 (141)
0A (141A) is inserted into these notches 142A and is pivotally supported. Further, the other end of each bracket 142 is directed substantially upward.

Above the shaft 144, a swinging roller 148 is supported by being spanned by the side plate 106, with its axes parallel to the shaft 144. This swing roller 148 has a notch surface 148A in a tangential direction facing the other end of each bracket 142, and the bracket 142 comes into contact with this notch surface 148A. In addition, as shown in FIG. 6, one of the swinging rollers 1
48, a lever 150 is provided extending downward along the plane. This lever 150 has a bent middle portion and a tip pointing further downward.

This lever 150 is indicated by the arrow A shown in FIG.
By being rotated in the direction (the imaginary line position in FIG. 6), the swinging roller 148 is rotated together with the lever 150. As a result, the bracket 14 is in contact with the notch surface 148A.
2 is swung around the shaft 144, and the presser roller 1
40 (141) moves in parallel and separates from the drive roller 138, allowing the photosensitive material 14 to be inserted between the pair of rollers 136.

[0038] This lever 150 holds the pressure roller 140
(141) is separated from the drive roller 138 (139), it protrudes from the opening closed by the opening/closing lid 120 (122), and the opening/closing lid 120 (122)
It has the role of preventing the closing operation of 2).

[0039] Also, this lever 150 is returned (FIG. 6).
(rotating in the direction opposite to the direction of arrow A shown in Fig. 6).
(solid line position), the swinging roller 148 is also rotated back. As a result, the bracket 142 is attached to the presser roller 140.
(141) is rotated around the shaft 144 by the weight of the drive roller 140 (141).
8 (139). Also,
The weight of the pressing rollers 140 (141) applies a nip force to the lower roller pair 136 (upper roller pair 137).

[0040] In this state, the lever 150 is completely accommodated in the opening and is retracted from the locus of movement during the closing operation of the opening/closing lid 120 (122).

[0041] That is, the pressing roller 140 (141)
When the photosensitive material is separated from the driving roller 138 (139), the opening/closing lid 120 (122) cannot be closed, and the photosensitive material is nipped between the pressing roller 140 (141) and the driving roller 138 (139). The opening/closing lid 120 (122) can be closed on the condition that the opening/closing lid 120 (122) is closed.

A cutter 116 is provided near the tip of the insertion guide 134 on the side opposite to the magazine 102, and after the photosensitive material 14 is cut along the width direction, the insertion opening 154, the guide 156, and the guide 160 (162) are cut. , 162 and transported to a transport unit 166.

The conveyance unit 166 is provided with a common guide 176 for guiding the photosensitive material conveyed from the respective magazine loading units 124 and 126, and the respective guides 160 and 16 are guided by roller pairs 172 and 174.
The conveyance paths of the photosensitive materials conveyed from No. 2 are aligned after this common guide 176.

Lead end detection sensors 182 and 184 are disposed near the roller pairs 172 and 174, and can detect the leading ends of the photosensitive materials 14 pulled out from the magazine loading units 124 and 126. In addition, common guide 176
A motor 188 for rotationally driving the drive roller 138 (139) is attached to the substrate 168 near the base plate 168 .

FIG. 7 is a perspective view of the drive type when the magazine loading section 100 is viewed from the back side of FIG.
64 includes an electromagnetic clutch 170 as a clutch means;
A gear 178 is attached via 171. A chain 180 is wound around and meshed with this gear 178. The chain 180 is connected to the rotating shaft 1 of the motor 188.
It also meshes with a gear 190 attached to 86.

The electromagnetic clutches 170 and 171 have the function of engaging the rotating shafts 164 of the drive rollers 138 and 139 and the drive shaft to which the gear 178 is attached by energizing the internal coils, and releasing the engagement by de-energizing them. A commercially available clutch is used (clutch manufactured by Shinko Electric Co., Ltd., model BO-5). The electromagnetic clutches 170 and 171 can be operated independently.

Chain 1 meshed with motor 188
80 denotes gears 192, 194 and idle gears 196, 198 attached to the rotating shafts of the roller pairs 172, 174.
The single motor 188 provides a driving source for the magazine loading section 100.

Therefore, the independent engagement and disengagement operations of the electromagnetic clutches 170 and 171 cause the magazine loading unit 1 to
Drive roller 138 or 1 of either 24 or 126
39 can be selectively applied with driving force.

Here, the tip of the photosensitive material 14 conveyed by the motor 188 is detected by the tip detection sensor 182 or 184.
After this is detected, the control device 800 drives the motor 188 by a predetermined amount to transport the photosensitive material 14 to a position where the leading end thereof protrudes from the guide 176.

Next, the operation of this embodiment will be explained. First, the magazine 1 is loaded into the magazine loading section 100 of the plate inspection production device 10.
The loading of 02 will be explained.

When inserting the magazine 102 into the magazine loading unit 126 on the upper side of the plate inspection device 10, release the lock (not shown) of the opening/closing lid 122, grasp the handle 130, and turn it counterclockwise in FIGS. 3 and 5. 2 to open the magazine loading unit 126 (the state shown in FIG. 2). Thereafter, the magazine 102 is inserted with the outlet 108 of the magazine 102 facing substantially upward and the surface to which the light reflection sheet 110 is attached facing the wall surface 104 on the back side of the magazine loading unit 126. At this time, positioning is performed by placing one end of the magazine 102 in the width direction along the side plate 106 of the magazine loading unit 126.

Thereafter, the lever 150 located at the top of the magazine loading unit 126 shown in FIG. 6 is rotated in the direction of arrow A. As a result, the pressing roller 141 of the roller pair 137 separates from the driving roller 139, and the tip of the lever 150 projects from the opening of the magazine loading unit 126.

In this state, the leading end of the photosensitive material 14 is pulled out from the magazine 102 and inserted into the roller pair 137, and then the lever 150 is rotated in the direction opposite to the arrow A direction and returned. As a result, the pressing roller 141 rotates around the shaft 144 due to its own weight, and a nip force is applied between the pair of rollers 137, so that the leading end of the photosensitive material 14 is clamped. After that, by closing and locking the opening/closing lid 122, the magazine loading unit 126 of the plate inspection device 10 is opened.
Loading of the magazine 102 into the magazine 102 is completed.

By the way, if the lever 150 is not rotated in the direction opposite to the direction of the arrow A, the tip of the lever 150 will interfere with the locus of the closing operation of the opening/closing lid 122. This prevents the operator from accidentally closing the opening/closing lid 122 without returning the lever 150. As a result, it is possible to deal with the problem before starting to drive the motor 188, and it is possible to omit processing after detecting an idle feed error.

On the other hand, the lower magazine loading unit 124
When loading the magazine 102 into the magazine loading unit 126, the same procedure as loading the magazine 102 into the magazine loading unit 126 is performed.

As a result, different types of photosensitive materials 14 are loaded into the lower magazine loading unit 124 and the upper magazine loading unit 126, and the operator selects one of them.

If it is the magazine loading unit 124 on the lower side that has been selected, the coil of the electromagnetic clutch 170 of the roller pair 136 corresponding to this magazine loading unit 124 is energized. As a result, the rotating shaft 164 of the drive roller 138 and the drive shaft to which the gear 178 is attached are connected, and the driving force of the motor 188 is transferred to the chain 180.
The photosensitive material 14 held between the lower pair of rollers 136 is conveyed.

On the other hand, the magazine loading unit on the side that is not selected (in this case, the upper magazine loading unit 126
), the coil of the electromagnetic clutch 171 is de-energized, so the rotating shaft 164 of the drive roller 139 and the gear 1
The drive shaft to which the roller 78 is attached is disconnected, and even if the motor 188 is driven, the drive roller 139 does not rotate.

In this way, each drive roller 138
, 139 are provided with electromagnetic clutches 170, 171, respectively, so that each drive roller 138, 139 can be independently driven by a single motor 188, which simplifies the structure.

Furthermore, since the motor 188 is single, there is no conveyance error that would occur if a separate drive source is provided, and post-processing such as positioning of the photosensitive material 14 is facilitated.

Next, the processing procedure of the plate inspection production device 10 is shown in FIG.
This will be explained according to the flowchart. In step 200, when the activation switch is turned on, step 202
Initialize each part. When the initial settings of each part are completed, the process moves to step 204, where initial conveyance control of the photosensitive material is performed. That is, the photosensitive material 14 is loaded from the magazine 102 housed in the designated magazine loading section 100.
is pulled out, cut into a predetermined length by the cutter 116, and then transported to the surface plate section 28 by the photosensitive material transport section 26.

In the next step 206, surface plate standby control is performed, and then in step 208, original film transport control is performed. That is, the original film 16 is placed on the overlay sheet 66 of the film loading section 36 and moved onto the surface plate section 28.

Next, in step 210, exposure standby control is performed, and then steps 212, 214, 21
In step 6, exposure processing control is performed. That is, in the case of a positive type photosensitive material, as the original film 16, a BK plate is stacked on a Y plate, a BK plate on a M plate, and a BK plate on a C plate, and these are stacked one on top of the other and brought into close contact with the photosensitive material 14 in order. Exposure is performed through a filter.

In the case of a negative photosensitive material, the original film 16 is a Y plate, an M plate, a C plate, and a BK plate.
4, and exposed through B, G, R, and BK filters.

When the exposure process is completed, the support base 68 is moved to the film loading section 36 and placed on standby, and the process moves from step 216 to step 218, where the exposed photosensitive material transport control is performed.

Next, in step 220, photosensitive material delivery control is performed. That is, the photosensitive material that has undergone exposure processing is transported to the processor section 34, and in step 222,
Development processing (development, bleach-fixing, and washing) is performed,
Next, the photosensitive material 14 that has undergone the drying process is placed in the casing 1.
The sample is taken out from an outlet 22 formed in 2.
