2. Description of the Related Art Conventionally, in a separation process in a plate making process, a color scanner is used to separate a color photograph into images of a plurality of colors (in standard color printing, four colors of yellow, magenta, cyan, and black). , A large number of images (hereinafter referred to as halftone images. Note that there are mainly halftone images and continuous tone images, but in the present invention, there is no difference between halftone images and continuous tone images). The formed film sheet is obtained. It scans color photos with a scanner,
Obtain color information of multiple colors, calculate halftone dot information from this color information, and based on this halftone dot information, print a halftone dot image on a film sheet (mainly a silver salt photosensitive film) with a laser etc. By exposing halftone images for yellow, magenta, cyan, and black for one sheet), the color photographs are separated one after another until the blank of the film sheet is exhausted, and halftone images are exposed. A film sheet on which a large number of halftone images are formed is obtained.

This film sheet is subjected to development processing and then cut into halftone images (hereinafter, the cut film sheet for each halftone image is referred to as a separate film), and a plurality of separate color films corresponding to color photographs are formed. They are organized together (one set of four sheets in standard color printing) and passed to the next step, the retouching step (step of pasting a separate film at a predetermined position).

The work of cutting a film sheet on which a large number of halftone images are formed to obtain a separate film has conventionally been a manual cutting work using scissors, but today, developed halftone images are used. A robot color scanner that can continuously output a large number of formed film sheets has been developed.Since a film sheet with a large number of halftone images is output continuously, the cutting operation by hand using scissors is a scanner operator. Therefore, the robot color scanner has to be operated for a short time, and the operation rate of the robot color scanner is reduced. There is also a problem that the work load is heavy because the cutting work is performed manually.

Therefore, the applicant of the present invention has proposed the following automatic film sheet cutting device. Japanese Unexamined Patent Publication No. 2-219058 detects a size of a film sheet and a color identification mark (a color identification mark is provided for each halftone image) which is cutting position information provided at a predetermined position on the film sheet, and detects the film. This is an automatic film sheet cutting device that judges the cutting position based on the size and color identification mark of the sheet and cuts the sheet. JP-A-3-264296 detects the size of a film sheet and a color identification mark provided at a predetermined position on the film sheet, judges the cutting position from the size and the color identification mark of the film sheet, and cuts the sheet. The separate film is an automatic film sheet cutting device that outputs a set of four sheets that are offset from each other, and are stuck and output. Further, Japanese Patent Application No. 2-163851 discloses a film sheet automatic in which a mark which is cutting position information is formed when a halftone dot image is exposed on a film sheet by a scanner by a scanner and the mark is detected to perform cutting. It is a cutting device.

However, these automatic film sheet cutting devices continuously output a film sheet on which a large number of developed halftone dot images have been formed by a robot color scanner, and then the human eyes inspect the halftone dot image of this film sheet. However, it employs a method of inserting the inspected film sheet into the automatic film sheet cutting device by hand.This method has the advantage of being compatible with robot color scanners made by multiple companies, but on the other hand, a color identification mark or Since it is necessary to detect the mark indicating the cutting position, it takes a lot of time to perform the cutting work, and the efficiency of the film sheet automatic cutting device itself is low.

Therefore, today, an automatic film sheet cutting apparatus has been developed which determines the cutting position of the film sheet by utilizing the position data at the time of halftone image exposure. FIG. 5 is a schematic view of a conventional disassembling process and a film sheet automatic cutting device, and a robot color scanner includes a setup device 3, a scanner scanning device 4, an output device 5, and a developing device 7. The color photographs 1, 1, ... Are attached to the transparent drum 2 and mounted on the setup device 3.
In the setup device 3, as separation conditions for each color photograph 1, the separation order of each color photograph 1, the position of the separation target area on each color photograph 1 on the transparent drum 2, the separation target area, and then the film. Magnification rate when exposing a halftone image on a sheet, tone curve, masking, highlight that are the conditions when calculating color information of multiple colors obtained by scanning each color photograph 1 with a scanner , A shadow is set, and the decomposition condition data is passed to the scanner scanning device 4 online or offline such as a floppy disk.

Next, when the transparent drum 2 to which the color photographs 1, 1, ... Are attached is attached to the scanner scanning device 4, the scanner scanning device 4 scans each color photograph 1 in accordance with the above-mentioned decomposition condition data, and each color photograph. The color information for 1 is obtained, the halftone dot information for four colors corresponding to each color photograph 1 is calculated from this color information, and this halftone dot information is sent to the output exposure device 5 online. Of course, the scanner scanning device 4 has a disassembling condition setting function, and the above-mentioned setup device 3
Although the disassembling condition setting work performed in step 1 may be performed by the scanner scanning device 4, in that case, since the operating efficiency of the entire robot color scanner decreases, normally, the disassembling condition setting work is performed by a plurality of setup devices 3, The scanner scanning device 4 is used exclusively for scanning the color photograph 1.

The output exposure device 5 exposes a halftone image on a film sheet wound around the exposure drum 6 with a laser (not shown) based on halftone information from the scanner scanning device 4. An unexposed film roll storage unit (not shown) inside the output exposure device 5, a predetermined amount of film is cut out from the unexposed film roll to be a film sheet, and a film sheet supply mechanism for winding the film sheet on the exposure drum 6, a dot image Has a film sheet discharge mechanism for removing the exposed film sheet from the exposure drum 6 and sending it to the first transport section 8. The film sheet can be automatically supplied and discharged, and a halftone image is continuously formed. Output a large number of formed film sheets.

The exposed film sheet is sent to the developing device 7 through the first transport section 8. The developing device 7 has a well-known structure, and the film sheet passes through a developing solution tank, a fixing solution tank, a water washing section, and a drying section, which are not shown, and the development is completed.
It is sent out to the carrying section 9 and sent to the automatic film cutting device 10 via the second carrying section 9. The film cutting position in the automatic film cutting device 10 is the disassembly order of each color photograph 1 among the disassembling conditions in the scanner scanning device 4 or the setup device 3, and the disassembly target area on each color photograph 1 on the transparent drum 2. Based on the position, the exposure start point and the end point of each halftone image obtained from the magnification when the halftone image is exposed on the film sheet after decomposing the decomposition target area, and the data regarding the edging interval to be attached to the exposure area Will be decided. The method for determining the cutting position based on the disassembling condition is described in detail in Japanese Patent Publication No. 3-10294.

FIG. 6 is a block diagram of the second conveying section 9 and the automatic film sheet cutting apparatus 10. The film sheet having a large number of developed halftone images formed thereon is conveyed on the second conveying section 9 in the direction of arrow A, and then placed on the cut table 11. A large number of suction holes 12 ... Are provided in the cut table 11, the film sheet is sucked and fixed onto the cut table 11 by these suction holes 12, and a cutter 68 is vertically supported by the support member 13. There is. The cutter 68 can be moved in the length direction of the cut table 11 (direction orthogonal to the arrow A) by a Y-direction drive mechanism (not shown). The support member 13 is moved in the width direction of the cut table 11 (arrow A
Direction).

A suction pad 14 is attached to the support member 13, and the film sheet on the second transport section 9 is placed on the cut table 11 by the suction pad 14.
The cut film sheet on the cut table 11 (hereinafter, the cut film sheet is referred to as a separate film) is conveyed onto the conveyor 15. The four separate films conveyed on the conveyor 15 are indicated by arrow B.
The sheets are conveyed in the direction and are packaged by the packaging mechanism 16 as a set of four sheets. In the figure, 17 is a wrapping roll, 18 is a wrapping roll cutting device that cuts the wrapping roll 17 that wraps the separate film by thermocompression bonding, and 19 conveys the wrapped separate film that has passed through the wrapping roll cutting device 18 to a stock box 20. It is a conveyor.

With the above construction, it is not necessary to detect the color identification mark or the mark indicating the cutting position for each cutting, the time for cutting work can be reduced, and the efficiency of the automatic film sheet cutting apparatus can be improved. Furthermore, by putting the developing machine and the film sheet automatic cutting device in-line, it is possible to make an integrated line from disassembly to cutting and packaging, and it is not necessary for the worker to place the film sheet on the film sheet automatic cutting device. By reducing the load and changing the film sheet cutting operation from the conventional batch processing to continuous processing, it becomes possible to quickly transfer the necessary separate film to the retouching process of the next process when needed, and the whole plate making process. Was able to increase the efficiency of.

[0014]

However, although the efficiency of the automatic film sheet cutting apparatus for consistently processing from cutting to packaging is improved, it has a problem that the separate film cannot be inspected. That is, a robot color scanner continuously outputs a developed film sheet on which a large number of developed halftone images have been formed, and then a human visually inspects the halftone images of this film sheet, and the inspected film sheet is manually detected. In the method of inserting into the automatic cutting device, there is a process in which humans visually inspect the halftone dot image of the film sheet before cutting, but in the film sheet automatic cutting device that consistently processes from cutting to packaging, the process of performing inspection Cannot be inserted, and the four separate films that have been packaged are stacked on top of each other and cannot be inspected from the outside. Therefore, it is necessary to take out the separate film from the bag for the inspection.

Particularly, the disassembling process by the scanner is the largest in the plate-making printing process, and the color and tone can be corrected, and the main part of the quality of the printed pattern is determined. Therefore, the quality of the separate film directly determines the quality of the printed pattern, but since the printed matter is visually evaluated, there is no absolute standard for the quality, and the quality is evaluated subjectively by human eyes. It is necessary to evaluate the suitability of setting decomposition conditions. In addition to the quality of color and tone, dust (if dust adheres to a color photo, the dust is also disassembled as part of the picture), pinholes on the film sheet, tone jump (colors are continuously changed like gradations). When there is a change in color, a large color change occurs and it looks like a line is drawn), moiré (generated by the line of the pattern in the color photo and the scanning angle of the scanner), and bilick (in the color photo). It is often the case that defects such as steps are generated when the straight lines of the pattern are used as halftone dots) and Newton rings (interference fringes are generated by the air between the color photograph and the transparent drum) on the separate film.

When the separate film having these defects has not been inspected and passed to the next process, the defect is found after the proof printing is completed in the proof printing process, and then the school inspection of the proof print ( This is a final inspection before submitting proof prints to the customer, and it is necessary to recreate after the discovery process until the disassembly process, so the work of multiple processes is wasted and not only the production efficiency of the plate making process is greatly reduced. , There is a problem that it will not be in time for delivery.

The problems in the automatic film sheet cutting apparatus for performing the integrated processing from cutting to packaging have been described above. Next, the film sheet on which a large number of developed halftone images are formed is continuously output from the robot color scanner. , Problems of the method of manually inserting the film sheet into the film sheet automatic cutting device will be described. Usually, the separate film is passed to the next process as a set with a corresponding color photograph, a disassembly instruction sheet, and the like. In this process, the number of separate films and color photographs is checked by checking the number of separate films and color photographs, and whether there is a difference from the instructions for disassembling by assembling a set of color photographs and disassembly instructions corresponding to the separate film. Therefore, after continuously outputting the film sheet, a person visually inspects the halftone image of this film sheet and manually inserts the inspected film sheet into the film sheet automatic cutting device. There is a problem that two steps, that is, a step of visually inspecting a halftone image with a human eye and a step of combining a separate film with a color photograph corresponding to a separation film and a separation instruction sheet after the cutting are required, and work steps are duplicated.

The problem to be solved by the present invention is to solve the above-mentioned drawbacks of the prior art, improve the efficiency of the cutting work by using the film sheet automatic cutting device and the disassembling / developing work as an integrated line, and at the same time, to separate the film. An object of the present invention is to provide an automatic film sheet cutting device capable of efficiently performing inspection. Also, even if it is not a consistent line,
To provide an automatic film sheet cutting device that can reduce the number of processes by combining the separate film inspection process and the process of checking the necessary items by combining the separate film with color photographs and disassembly instructions. is there.

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic view of an automatic film sheet cutting apparatus according to the present invention. Reference numeral 21 in the drawing denotes a film sheet transporting unit, which is connected to a developing device (not shown). After the development, the film sheet 22 on which a large number of halftone images are formed advances in the direction of the arrow C in the film sheet conveying section 21 by the rotating feed rollers 23 ,.
Abut and stop. Next, the film sheet 22 is fed in a direction orthogonal to the arrow C by the rotating feed roller 25, and comes into contact with the retractable pad 26 to stop, so that the film sheet 22 can be constantly stopped at a predetermined position. It will be possible. When the feed roller 23 rotates, the feed roller 25 is raised by an up / down mechanism (not shown) and is in a position where it does not come into contact with the film sheet 22, and when the feed roller 25 comes down and comes into contact with the film sheet 22, it rotates. , Are raised by an up-and-down mechanism (not shown) and are separated from the film sheet 22.

In the figure, reference numeral 27 is a cut table, and a cutter 28 is provided above the cut table 27 so as to be vertically supported by a support member 29. The cutter 28 can be moved along a support member 29 by a Y-axis direction (direction orthogonal to the arrow C) drive mechanism (not shown). Further, the cutter itself moves up and down and rotates to select whether or not to cut and the cutter. The direction of the blade can be changed. The support member 29 is movable along the cut table by an X-axis direction (arrow C direction) drive mechanism (not shown). Suction pads 30, 30 ... Are provided on the support member 29, and the suction pads 30, 30.

The film sheet 22 contacting the pads 24, 26 and stopped at a predetermined position is sucked by the suction pad 30 provided on the support member 29 moved to the position a in the figure, and the support member 29 is arrowed. As it moves in the direction of C, it is conveyed onto the cut table 27. At this time, hit 2
4 moves down to avoid contact with the film sheet 22 being conveyed. When the support member 29 and the film sheet 22 transported by the suction pad 30 reach the predetermined position on the cut table 27, the support member 2 is sucked by the suction pad 30.
9 stops, the suction pad 30 descends, and the film sheet 2
2 is placed on the cut table 27. The cut table 27 is provided with innumerable suction holes 31, the film sheet 22 is sucked and fixed in the suction holes 31, and the suction pad 30 stops suction and rises. Film sheet 2
2 is constantly stopped at a predetermined position by the pads 24, 26, and then sucked by the suction pad 30 to support the support member 2
Since the sheet 9 is conveyed by 9, the suction position of the film sheet 22 placed on the cut table 27 can be set to a predetermined position by setting the moving distance of the support member 29 to a predetermined value. This predetermined position is arbitrarily determined as long as it is within the cutting range of the cutter 28.

The film sheet 2 sucked into a predetermined position
2 is cut by the cutter 28 for each halftone image. This cutting position is determined based on the data from the set-up device or the scanner scanning device, which is the data regarding the exposure start point and end point of each halftone image and the edging interval to be attached to each halftone image (exposure area). Since the details are described in Japanese Examined Patent Publication No. 3-10294, the description thereof will be omitted here.
After the film sheet 22 has been cut and cut for each halftone image, a suction pad 3 is provided for each line of the separate film.
0 goes down, and after sucking it up. Next, the support member 29 moves in the direction of b in the drawing while the separate film is adsorbed by the suction pad 30, and conveys the separate film onto the transparent base film 32 on the attachment table 36.

The transparent base film 32 is unwound from a transparent film roll 33, and is sent out onto a sticking table 36 via a roller 34. Transparent over film 37
Is unwound from a roll (not shown), and the roller 38,
The transparent base film 32 and the transparent overfilm 37 are superposed by the first feed roller 40 on the sticking base 36 via the sandwiching roller 39, and stand by. The separate film adsorbed by the suction pad 30 and conveyed is the transparent base film 3 on the attachment table 36.
When the sheet is placed on the upper surface of the separate film 2, the nipping roller 39 descends while rolling out the transparent overfilm 37 in the direction of the arrow D (direction of the attachment table 36), and the tip of the placed separate film is moved to the transparent overfilm 37. It is sandwiched with the transparent base film 32 via. After that, the suction pad 30 stops the suction, lifts the separate film apart, and the support member 29 moves to the suction position of the next separate film.

The first feeding roller 40 is the suction pad 30.
Stops sucking, releases the separate film, and then starts rotation, and sends out the transparent base film 32 and the transparent over film 37 holding the separate film in the direction of arrow C, and the tip of the separate film is the first feed roller 4
When reaching 0, the nip roller 39 moves upward in the direction of arrow E,
Return to the standby state. When no welding, cutting, or sewing process is performed, the transparent base film 32 and the transparent over film 37 with the separate film sandwiched between them are wound up by the winding roll 41 as they are, and are conveyed to the plate inspection place in the wound state. , It is rolled out little by little and the plate inspection is performed.
In this case, since Y, M, C, and BL are aligned without the separate films being mixed with each other, it is possible to efficiently perform the plate inspection, and the transparent base film 32 and the transparent over film 37 can be used many times. Although there is an effect that it can be reused, it is necessary to separately fix the unwound separate film with tape etc. after the plate inspection, and furthermore, the plate can be inspected only in the order of unrolling, and the separate film in the middle There is a problem that it is not possible to prioritize film inspection in an emergency.

Next, the case of applying welding, sewing, etc. will be described. In the figure, 42 is the left and right welding rollers, and 43 is the second
A feed roller, 44 is a third feed roller, and 45 is a front and rear welding sewing machine processing section. The transparent base film 32 and the transparent over film 37 sandwiching the separate film fed out through the first feed roller 40 are provided on the left and right sides of the separate film sandwiched by the left and right welding rollers 42 heated by a heating device (not shown). It is heat-welded, and is fed to the front-back welding machine processing section 45 via the second feed roller 43. The mechanism of the front and rear welding sewing machine processing section 45 will be described later, but the transparent base film 32 and the transparent over film 37 are welded before and after the sandwiched separate film, and at the same time, are machined, and the third feed roller 44 is After that, it is wound around the winding roll 41.

In this case, it is conveyed to the plate inspection place in a wound state. The separate film is welded on the front, back, left and right in a state of being aligned for each of Y, M, C and BL, and perforations are provided on the front and back to enable efficient plate inspection.
Further, the separate film does not need to be separately fixed with a tape or the like after the plate inspection, and the plate inspection can be performed while being sandwiched, and can be easily separated by the sewing machine processing portion when passing to the next process. . The present invention is not limited to the present embodiment, and it is also possible to perform regular folding at the perforations like output paper of a computer or the like without taking up with the take-up roll 41. In that case, it is sufficient to simply remove the winding roll 41 and install the pedestal, and the plate inspection can be performed from the separate film located at an arbitrary position. Therefore, the separate film in the middle is prioritized in case of emergency. It becomes possible.

Next, the case where welding, cutting and the like are performed will be described. When performing the cutting process, the sewing blade of the front and rear welding machine processing section 45 is replaced with a cutting blade, and the winding roll 41
A cradle may be installed instead of. In this case, the front and rear and / or the left and right of the separate film are welded in a state of being aligned for each of Y, M, C, and BL, and the front and rear are cut, which makes it possible to efficiently perform the plate inspection. The film does not need to be separately fixed with a tape or the like after the plate inspection, and the plate can be inspected while being sandwiched, and can be directly passed to the next step. Further, since it is possible to perform the plate inspection from the separate film located at an arbitrary position, it is possible to prioritize the plate inspection in the intermediate film in the emergency.

The present invention is not limited to this embodiment, and the welded portion may be any combination of front, rear, left and right as long as the alignment of the separate film does not move easily. For example, it may be one of front, rear, left and right, or one side of front, rear, left and right, two adjacent sides such as rear and left, and three sides such as rear and left and right. In that case, it is possible to simply stop the heating of the portion that is not welded, but the heating mechanism itself for that portion may be excluded. In this case, since either the front, rear, left or right side of the separate film is opened, the separate film can be easily taken out from the opened portion in the next step. In addition, color photographs and disassembly instructions (magnification,
When a set such as trimming) is set in a separate film and passed to the next step, it is possible to easily insert a color photograph or a disassembly instruction from the open portion. That is, the separate films need to be lined up until the plate inspection, and it is not necessary to line up after the plate inspection is completed, and there is no problem even if a color photograph or a disassembly instruction sheet is inserted. Therefore, by inserting a color photograph, disassembly instruction sheet, etc. easily from the open part, it is possible to save time and effort to attach the color photograph, disassembly instruction sheet, etc. to the film that holds the separate film, and at the same time transporting to the next process. It is possible to prevent the adhered portion from peeling off and separating the separate film from the color photograph 1 and the disassembly instruction sheet.

FIG. 2 is a top view of this embodiment. In the figure, the support member 29 moves to the position of b, and the suction pad 3
No. 0 adsorbs the separate film 46a, and the separate film 46a is placed on the transparent base film 32 on the attachment table 36 in a state of being aligned in Y, M, C, and BL. The nipping roller 39 descends toward the attaching table 36, and nips the tip of the separate film 46a via the transparent over film 37. In this embodiment, since the width of the separate film 46a (width in the direction orthogonal to the arrow C) corresponds to two types (wide and narrow),
There are six suction pads 30 (two for wide width, two for narrow width, and two for common use). FIG. 2 shows a wide case, and two of the suction pads 30 are not adsorbed.

In the figure, reference numeral 46b denotes a separate film placed in front of the separate film 46a, and the transparent base film 32 and the transparent overfilm 37 are welded on both sides of the separate film 46b by the left and right welding rollers 42. Reference numeral 47 in the drawing denotes a left and right welded portion. The left and right welding rollers 42 rotate and perform welding in accordance with the progress of the transparent base film 32 and the transparent over film 37 holding the separate film therebetween. While the suction pad 30 places the separate film on the transparent base film 32, When the progress of the transparent substrate film 32 and the transparent over film 37 holding the separate film is stopped, the progress is raised by a not-shown vertical mechanism to prevent excessive welding.

The position of the left and right fusing rollers 42 in the width direction (the direction orthogonal to the arrow C) can be set freely.
The width is set according to the width of the separate film 46a. When the position of the left and right welding rollers 42 in the width direction can be automatically set, the left and right welding rollers 42, the vertical device, and the heating device are regarded as one unit, and the unit can be driven along a rail extending in the width direction. . The rail is an attachment table 36
It is installed between the upper first feed roller 40 and the second feed roller 43, and the stop position thereof may be determined from the data from the set-up device or the scanner scanning device, and the stop position of the transparent base film 32 or the transparent over film 37 may be determined. A sensor for detecting the width size or a switch for setting may be installed to determine the stop position from the data.

In the figure, reference numeral 46c denotes a separate film placed in front of the separate film 46b. Between the separate films 46b and 46c, the front and rear welding machine processing portions 45 allow the front of the separate film 46b and the back of the separate film 46c.

Reference numeral 53 in the drawing denotes a scanner and a scanner disassembling condition setting device, and halftone dot image position information from the scanner and / or the scanner disassembling condition setting device is input to the conveyance / cutting control device 54, and its cutting position and supporting member at the time of cutting. The position of the cutter and the position of the cutter, the position of the support member at the time of conveyance, the position of the suction pad, and the like are calculated. In the figure, 55 is a film sheet position confirming means, which sends operation start information to the conveyance / cutting control device 54 when the film sheet reaches a predetermined position of the film sheet conveying section 21 of FIG. Although the film sheet position confirming means 55 is not particularly shown in FIG.
Alternatively, it may be installed in the vicinity thereof. The conveyance / cutting control device 54 receives the operation start information of the film sheet position confirmation means 55 based on the calculation result calculated from the halftone image position information from the scanner and / or the scanner disassembly condition setting device, and then starts supporting member drive circuit. 56, the cutting means drive circuit 57, the suction pad drive circuit 58, and the cut table suction hole drive circuit 59 perform conveyance / cutting and suction start / stop operations for the cut table suction holes.

From the transport / cutting control device 54 to the film sandwiching control device 60, halftone dot image position information from the scanner and / or scanner disassembly condition setting device or cutting position information calculated by the transport / cutting control device 54 is sent. . Based on this information, the welding position calculating means 61 and the cutting position calculating means 62 calculate the welding position and the cutting position according to the size of the separate film, and the feed amount calculating means 63 determines the separate film according to the positions. The feed amount of the transparent substrate film 32 and the transparent over film 37 sandwiching the sheet and the feed start and stop timings are calculated. These calculations may be performed based on the welding position calculation result, or may be calculated separately.

Operation start information is sent from the transport / cutting control device 54 to the film holding control device 60 when the separate film is placed on the transparent substrate film 32. In response to this, the film pinching control device 60 causes the welding means drive circuit 64, based on the calculation result of the welding position, the cutting position, the feed amount, and the feed start / stop timing.
The cutting means drive circuit 65, the feeding means drive circuit 66, and the nip roller drive circuit 67 are operated. The welding means driving circuit 64 operates the left and right welding rollers 42 and the front and rear welding sewing machine processing section 45 in FIG. 1, and the cutting means driving circuit 65 operates when the welding section, the sewing machine processing section and the cutting section are installed separately. Operates the sewing machine processing section and cutting section. The feeding means driving circuit 63 is, in FIG. 1, a first feeding roller 40, a second feeding roller 43, a third feeding roller 44,
The take-up roll 41 is operated, but this may be only the take-up roll 41 or only the proper feed roller.

Next, a case will be described in which a film sheet on which a large number of developed halftone images have been formed is continuously output from a robot color scanner, and then the film sheet is manually inserted into a film sheet automatic cutting device. In that case,
In, the film sheet may be manually inserted from the direction of arrow C. Alternatively, the feed roller 23 may be excluded and the film 24 may be directly placed on the pads 24 and 26 while being manually applied. Furthermore, the film sheet may be manually placed on the cut table 27,
In that case, the film transport section 21 is excluded, and the pads 24, 26 are
Is provided at an appropriate position on the cut table 27 so as to be retractable. Furthermore, when it is not based on the position information of the halftone image from the scanner and / or the scanner disassembly condition setting device, Japanese Patent Application Laid-Open No. 2-219058 disclosed in the prior art,
It may be based on the cutting position information recorded on the film described in JP-A-3-264296 and Japanese Patent Application No. 2-163851. In that case, the scanner and the scanner disassembly condition setting device 53 of FIG. 4 serve as a sensor for identifying the cutting position information recorded on the film sheet, and the film sheet position confirmation means is for the film sheet to be inserted and placed by hand. It will be installed at a proper position according to the form.

The present invention is not limited to this embodiment, and the fact that the cut film sheets do not overlap each other means that the halftone images of the cut film sheets do not overlap each other. This includes the case where the margins around the halftone image overlap. In this case, the suction pad 30 shown in FIG. 2 is not fixed to the support member 29, and a drive device that moves left and right may be installed. Further, as the driving amount, the amount of blank space is calculated from the position information of the halftone image and the cutting position, and the amount of blank space or less is set as the driving amount. As an effect, the widths of the transparent base film 32 and the transparent over film 37 can be narrowed to save the film. Furthermore, cutting and perforation processing may be used together. In that case, the separate film is divided into several groups, cut into each group, and perforated inside the group to make it easier to hand over to the next step.

Furthermore, the present invention is not limited to this embodiment, and a publicly known weak adhesive film may be used for the transparent base film and / or the transparent over film instead of the welding. That is, the weakly adhesive surface of the weakly adhesive film sheet may be a surface for sandwiching the separate film (a surface in contact with the separate film), and the left and right welding rollers 42 and the front and rear welding sewing machine processed portions in FIG. 1 may be removed. When the sewing process and / or the cutting process is required, a separate sewing process part and / or cutting part may be installed, and the installation is performed by removing the position of the front and rear welding sewing process part 45 and the third feed roller 44 in FIG. It may be at that position or after the third feed roller 44. The machine processing section and / or the cutting section may be a sewing machine blade extending over the entire width of the transparent base film 32 and the transparent over film 37, or a mechanism for moving the cutting blade up and down, but simply using a rotary sewing machine blade and a rotary cutter as the transparent base film 32. The transparent over film 37 may be run over the entire width. Of course, when cutting, the take-up roll 41 is unnecessary, and a pedestal or the like is arranged at the position of the take-up roll 41. In this case, the unit price of the film increases and the cost increases, the transparency decreases due to the effect of the adhesive, the difficulty of inspecting increases because it is difficult to distinguish between the dust adhered to the adhesive and the dust and scratches of the separate film. However, the welding process itself can be omitted, and the mechanism can be simplified and the separate film can be easily taken out in the next process. Color photograph 1 even when it is delivered to the next process as a set with separate film etc.
It is possible to squeeze again by disassembling and disassembling instructions as a set with the separate film.

As described above, the automatic film sheet cutting apparatus according to the present invention improves the efficiency of the cutting operation with the film sheet automatic cutting apparatus as an integrated line for disassembly and development work, and at the same time, separates the separate films from each other. Since it is sandwiched between the transparent base film and the transparent over film to output so that they do not overlap, if it is placed on a light table etc., inspect the cut film sheets one by one while sticking on the transparent base film. In addition to the quality of color and tone, the efficiency of inspecting for defects such as dust, film sheet pinholes, tone jumps, moire, bilicks, and Newton's rings is improved, and before passing the separate film to the next process. Since inspection is possible and there is no need to go back to the disassembly process after discovery, there is no need to rework multiple processes. Not not significantly reducing the production efficiency of the plate-making process, it is also not the problem arises not in time to delivery. Even when the lines are not integrated, it is possible to reduce the number of processes by combining the separate film inspection process and the process of combining the separate film with the color photograph and the separation instruction sheet as one set.

Further, according to the present invention, the transparent base film and the transparent over film having the separate films sandwiched therebetween are welded at predetermined positions so as not to overlap each other so that the separate film does not fall between the transparent base film and the transparent over film. At the same time, it prevents scratches, stains, breaks, etc. that occur when the separate film comes into direct contact with other objects. Furthermore, perforation processing is applied to facilitate separation, and the work of separately fixing the separate film with tape or the like is omitted, and the main folding is performed along the perforations, or
By cutting, the separate film at any position can be taken out as needed, the separate film can be inspected in any order, and the separate film in the middle can be prioritized in an emergency to perform the plate inspection. . Furthermore, by combining the welded part in either the front, rear, left, or right, either the front, back, left, or right of the separate film can be opened, and the separate film can be easily taken out from the open part in the next step. In the case where the etc. and the disassembly instruction sheet are set together with the separate film and passed to the next step, it is possible to easily insert the color photograph 1 etc. and the disassembly instruction sheet from the open portion.
