DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film sticking apparatus used for photolithography.

[0002]

2. Description of the Related Art In general, in photolithography, a color separation plate (either a positive film or a negative film) for each document output from a color scanner is mounted on a backing sheet (made of a transparent film, also referred to as a base film) according to an assignment designation. ) And the original plate film for printing plate printing is being created. The registration between the color plates at the time of pasting is performed by first looking at the original plate film (usually a magenta plate), placing a mount of another color on it, and visually checking the color separation plate by the operator. Was pasted on the backing paper. As described above, in the past, the operator performed registration while confirming one plate at a time with the naked eye, so that the degree of fatigue of the worker was large and time-consuming, the work efficiency was poor, and the registration was difficult. There were individual differences in accuracy, and it was difficult to produce high quality original film. Especially in recent years,
In the case of newspapers, color photographs are sometimes placed. In general, paste is performed in units of two-page spreads. In the case of newspapers, the size of the backing sheet and color separation plate is large, and the paste is performed accurately in a short time. It was very difficult.

[0003] Therefore, it is desired to automate the pasting, and several pasting apparatuses have been considered. When placing a color photograph on a newspaper, the scanner assigns and designates the photograph and outputs a color separation. The size of the color separation plate is different depending on the size of the photograph, and portions of the mount other than the photograph are shaded in advance. For example, if the photo has only one page, the size of the color separation plate is one page, and the mount is transparent (windows) at the portion corresponding to the page, and the portions corresponding to the remaining pages are already shaded. I have. In this way, by attaching the color separation plate to the window of the mount, it is possible to prepare a photographic original plate film. In the pasting device considered at present, the color separation plate and the backing sheet are set in a predetermined order and at a predetermined position in the tray, and when the apparatus is operated, the backing sheet and the color separation plate are automatically taken out from the tray, and the backing sheet is mounted. The color separation plate is registered above, and the color separation plate is attached with a tape or the like and discharged.

Here, it is considered that the mount and the color separation plate are taken out from the tray by air suction. However, a plurality of the mount and the color separation plate may be taken out due to static electricity or the like. . For this reason, the sticking may not be performed in the set order.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to cope with the above-mentioned circumstances, and an object of the present invention is to take out a backing sheet and a color separation plate one by one from a tray by air suction, and place the color separation plate on the backing sheet. When pasting, make sure that the backing sheet and color separation
An object of the present invention is to provide a film sticking apparatus which can take out sheets one by one and stick the sheets in the order in which they are set on a tray.

[0006]

According to the film sticking apparatus of the present invention, even if two or more sheets and a color separation plate are adsorbed when the mount and the color separation plate are automatically taken out from the tray, the second and subsequent sheets are elastic. Since only one sheet can be taken out from the tray because it is peeled off by the member, the film is automatically attached by simply setting the backing sheet and the color separation plate on the tray. And a high quality original film can be efficiently produced.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a film sticking apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing the appearance of the embodiment, and FIG. 2 is a schematic diagram showing the internal structure thereof.

A key switch section 12 is provided on the apparatus main body 10.
And a CRT monitor 14 are provided. On the front surface of the apparatus main body 10, a backing sheet for pasting (also referred to as a base film)
And a color separation plate (a positive film or a negative film may be used, but a negative film is used here. In the following, the film is also simply referred to as a film), and a tray section 16 for accommodating a mount on which the film is pasted is provided. The key switch unit 12 is for giving various commands to the device.
The CRT monitor 14 is for notifying an operator of the operation state of the apparatus and various warnings. The CRT monitor 1
4 may be output by a printer (not shown). The color separation plate affixed to the mount for each color is negative / positive inverted by a printer to be an original film for each color.

Here, in the case of a newspaper, the backing paper has a size of two spread pages, and the size of the color separation plate outputted from the scanner is 12 or 15 single-page spreads, or two spread pages.
There is a page (15 columns) size. Although a photograph may not be printed over the entire width of a newspaper, the color separation is always output in the size of the full width of the paper (single page or both pages). Therefore, in the color separation plate, the photograph is allocated and arranged at a desired position, and the other part is a light shielding part. The mount is also shielded from light except for the portion where the color separation plate is pasted. In the case of this embodiment, nine types of mounts are prepared according to the paste pattern as shown in FIG. 3, and a mount suitable for the size of the color separation plate and the paste position (location) is selected and set. You. The shaded portion in FIG. 3 is a light shielding portion, and a color separation plate is attached to a white portion (window portion). In the case of newspaper printing, the photo part is Y (yellow), M (magenta), C (cyan), K
This is performed in the 4th version of (Sumi), and the character portion is performed in the exclusive monochrome version. Therefore, a total of five color separation plates are required for one printed material.

Inside the device, as shown in FIG.
The tray section 16 is held by a pair of left and right holding frames 18a and 18b, and is slidable in the front-rear direction. As a result, the tray section 16 is inserted into the main body, and the mount and the color separation plate in the tray can be automatically taken out or pulled out of the main body, and the mount and the color separation plate can be set in the tray. An upper table (hereinafter, referred to as a Z table) 20 and a lower table 22 are provided in parallel in the main body at the rear portions of the holding frames 18a and 18b, and the tray section 16 is Enter between the tables. The movement of these tables is performed by a rodless air cylinder.

The tray section 16 includes a backing sheet and a film tray for accommodating a backing sheet and a color separation plate before pasting.
There are a total of five trays, one set and one plate discharge tray that stores the backing paper after the film is pasted. Here, the first and second film trays 24 and 26, the first and second
Are provided, and the plate discharge tray 32 is disposed. As described above, since two sets of trays each containing the mount and the color separation plate are provided, one set of trays is operated (during the period of removing the mount and the color separation plate from the trays), and then to another set of trays. Mounts and color separations can be set, improving work efficiency.

When one of the trays is inserted into the apparatus main body and enters just below the Z table 20, the Z table 20 is lowered, and a vacuum device (not shown) sucks the mount and the color separation plate from the tray. Then, when the tray returns to the original position (the position shown in FIG. 2), the tray is further lowered, and the suction is stopped, so that the mount and the color separation plate are placed on the lower table 22. A vacuum device is also provided on the lower table, and the mounted mount and color separation plate are fixed by suction. The lower table 22 is used for positioning the mount and the color separation plate when the mount or the color separation plate is placed, that is, in order to register the color separation plate, that is, left and right (X) and front and rear (Y) in the horizontal plane. And can also rotate in the θ direction. for that reason,
Hereinafter, the lower table 22 is referred to as a θ table. Details of the θ table 22 are described in Japanese Patent Application No. 3-76395 by the same applicant.
, No. 3-120437, and No. 3-120438, and the description is omitted.

Although not shown, the mount is colored in different colors.
The θ table 22 is provided with an optical sensor for detecting when the mount is attracted to the Z table 20. The color separation plate is also provided with an identification mark indicating each color and odd / even pages, and the optical sensor of the θ table 22 also detects this identification mark. The size, position, and the like of the color separation plate are identified by the optical sensor detecting the size and position. Based on the identification result, it is checked whether the paste pattern of the mount shown in FIG. 3 and the color separation plate are matched with respect to size, set position, orientation, and the like,
If there is a mismatch, warn of this. As a result, it is possible to detect a mistake in setting the backing sheet and the color separation plate on the tray section 16 and prevent erroneous attachment.

In FIG. 2, for convenience of explanation, the tray is supported by two support frames 18a and 18b.
Actually, as shown in FIG. 4, a support frame is provided for each tray. Moreover, the support frame of each tray has a double structure. Describing the case of the tray 30, the tray main body 30a is attached to the first support frame 30b so as to be slidable back and forth, and the first support frame 30b is attached to the second support frame 30c so as to be slidable back and forth. . The second support frame 30b is provided inside the apparatus main body (between the Z table 20 and the θ table 22). Then, as shown in FIG.
The support frame 30b projects from the second support frame 30c toward the front side of the apparatus, and the tray body 30a is connected to the first support frame 30b.
Located on top. This state corresponds to the state in FIG.
The tray main body 30a and the first support frame 30b are driven back and forth by a rodless air cylinder (not shown). When the air cylinder is off, the tray body 30a
Can be manually driven back and forth. Therefore, when setting the mount, the color separation plate, and collecting the mount on which the film is pasted from the plate discharge tray 32, the air cylinder is turned off, and the tray main body 32a is moved from the first support frame to the position indicated by the dashed line in the drawing. If it is pulled out, the mount can be easily collected. afterwards,
The tray main body 32a is at the original position (the position indicated by the solid line in FIG. 4).
When the apparatus is operated again by pushing the tray main body 30a to the first support frame 30b, the first main body 30a is fixed to the first support frame 30b.
Is driven rearward (to the right in FIG. 4) along the second support frame 30c together with the tray main body 30a, and is inserted into the apparatus main body. And Z table 2 which descended
At 0, the mount and the color separation plate are taken out of the tray main body 30a. The mount on the θ table 22 after the film is pasted thereon is also adsorbed by the Z table 20, and the Z table 20
Is lifted, and is stored in the plate discharge tray main body inserted below the Z table 20. The air cylinder is turned off and the apparatus is started by operating the switch of the key switch section 12 shown in FIG.

As described above, during operation of the present apparatus, the tray section 16 is automatically inserted into the main body, and then moves back and forth to return to the original position. If the hand is pulled into the device as it is or if the hand is carelessly inserted into the device when the tray is in the device,
It is desirable that an operator keep his hands away from the apparatus because the hands may be pinched when the tray returns. Therefore, in this embodiment, a beam sensor that irradiates a beam in the horizontal direction on the front surface of the apparatus is provided for each tray. The hatched circular area in FIG. 4 indicates the detection range of the beam sensor. Therefore, when a part of the body of the operator, for example, a hand approaches the front of the handle of the tray on the front of the main body, the beam is cut off, and this is detected. The detection result is warned by a buzzer or the like. This prevents the worker from inadvertently approaching the tray with his / her hand and encountering an accident. However,
As described above, two sets of the backing tray and the film tray are provided, respectively. While one set is in operation, the backing sheet and the color separation plate can be set on the other set of trays so that the next work can be prepared. Therefore, if the beam sensor is always working, a warning is issued even when preparing for the next operation, which is bothersome. Therefore, only the beam sensor in front of the tray currently being operated is selectively operated. As a result, it is possible to selectively detect only the approach to the tray in operation, and to generate an effective warning.

Although not shown, doors that can be opened and closed are provided on the side and the back of the apparatus main body to check the inside of the apparatus in case of a malfunction such as a jammed color separation plate or mount. The door is provided with a door switch that can be opened and closed, and similarly, safety measures such as detecting the opening of the door during operation of the apparatus and issuing a warning or stopping the operation of the apparatus are taken.

Next, the internal structure of the tray will be described. Although not shown, the mounting sheet is provided with positioning pin holes, and corresponding pins are provided in the mounting sheet trays 28 and 30, so that when the mounting sheet is set in the tray, the pins are inserted into the pins. Positioned with respect to. When the backing sheet is removed from the tray, the pin is lowered and buried in the tray to facilitate removal. Each of the mount tray and the film tray can store five (Y, M, C, K, monochrome) color separation plates. The plate discharge tray 32 can accommodate up to 10 sheets of backing paper. If the backing with the film pasted on one side (page 1) of two facing pages is reset on the backing tray, a color separation plate can be pasted on the other half (other page), so-called additional pasting is also possible.

FIG. 5 is a plan view of the film trays 24 and 26.
Shown in As described above, the mount has a size of two newspaper spreads, and the color separation plate has two sizes of 12 rows and 15 rows for each page unit. If the left and right pages have the same number of steps, a spread color separation plate is made. If the number of steps is different, it is necessary to make a color separation plate for each of the left and right pages and set them on the left and right in the tray. Here, since the size of the color separation plate is slightly larger than the backing paper, if the color separation plates are arranged side by side, the central portion overlaps, it is difficult to take out the tray, and it is difficult to set the tray. Therefore, in order to correctly set the color separation for each page in the corresponding area on the film tray,
A plurality of separators 40 (here, two) are provided at the center. As shown in the cross-sectional view of FIG. 6, the separator 40 has a protrusion having a substantially S-shaped cross-sectional shape so that the color separation plates of the left and right pages can be vertically separated and overlapped. The separator 40 is rotatable about an axis 42, and when setting a two-page spread color separation plate, the projection is buried in the tray as inverted as shown by the broken line, and the bottom surface of the tray is flattened. It does not interfere with the color separation set for two pages.

A film holder 44 is provided at a position corresponding to an end on the near side of the 12-stage and 15-stage color separation plates so that color separation plates with different numbers of stages can be set at correct positions. The film retainer 44 is axially supported along the horizontal direction, is raised before setting, lowers the color separation plate after positioning the rear end thereof at the rear end of the tray, and lowers the color separation plate.
Fix the color separation.

The bottom surface of the rear end portion 46 of the film tray is a slightly inclined portion. Further, an elastic member 48 is provided on the rear end wall surface for peeling off the second and subsequent color separation plates when a plurality of color separation plates are sucked by the Z table 20. Note that the inclined portion and the elastic member are not limited to the film tray, but are common to the mount tray. These are provided so that color separation plates and mounts can be taken out one by one without fail. Hereinafter, details of the rear end portion of the tray will be described.

FIG. 7 shows details of the rear ends of the mount tray and the film tray. A spacer 60 is provided on the bottom surface of the rear end, and a slope plate 62 is provided on the spacer 60, thereby forming a rising slope. Also,
An elastic member 64 made of sponge rubber or the like is provided on the upper end of the rear wall.
Are projected horizontally. The elastic member 64 is a Z table 2
If a plurality of mounts and color separation plates are likely to be attracted due to 0, the second and subsequent sheets are peeled off. Therefore, the elastic force of the elastic member 64 is controlled by the Z table 20 described later.
It is set so that the backing sheet and the color separation plate are peeled off with a force weaker than the suction force of the ink. A roller 66 is mounted outside the rear wall of the tray. This is to ensure that when the mount or the color separation plate is adsorbed on the Z table 20, the return of the tray is performed, so that the Z table 20 is surely adsorbed. Hereinafter, an operation of taking out the backing sheet or the color separation plate from the tray and adsorbing it on the Z table 20 will be described with reference to FIG.

As shown in FIG. 8A, when the tray is completely inserted into the apparatus main body (immediately below the Z table 20), the Z table 20 is lowered. In the Z table 20,
As shown in FIG. 9, a large number of suction pads 84 are provided in the periphery of the table, and finer suction holes 86 are formed on the entire surface of the table. That is, the mount and the color separation plate are sucked by the suction pads 84 in the peripheral portion, and the suction holes 86 are formed on the entire surface.
And is absorbed by the Z table 20. When the Z table 20 is lowered, a vacuum device (not shown) operates. Here, since the rear end of the tray is raised, the mount and the color separation plate are first sucked from the rear end. Here, even if a plurality of mounts and color separation plates are likely to be collectively adsorbed due to static electricity or the like, the second and subsequent sheets are peeled off by the action of the elastic member 64 as described above, and the top mount, Only the color separation is adsorbed on the Z table 20. Further, in order to surely perform the peeling, the Z table 20 may be slightly moved up and down at this time. As a result, the second and subsequent mounts and color separation plates are shaken off.

Thereafter, as shown in FIG. 8 (b), when the tray is ejected from the apparatus main body, the backing sheet, the back end of which is adsorbed on the Z table 20, and the other portion of the color separation plate are placed on the tray. Is pressed against the Z table 20 by the roller 66 in accordance with the return of, and is completely attracted to the Z table 20.

When the color separation plates of the left and right pages are set side by side using the separator shown in FIG. 6, the color separation plates on one side are taken out one by one. In this case, only the suction pad 84 on the take-out side is operated to suction, and the other suction pad 84 on the color separation side which is not taken out is operated so as to blow air, and the color separation plate not taken out by air is pressed against the tray. .

Here, since a tape sticking unit (to be described later) is also provided on the Z table 20, an opening 82 for tape sticking is provided in the Z table 20, as shown in FIG. Tape attaching head (to be described later)
Moves up and down, and affixes the film to the mount on the θ table 22 with tape.

FIG. 10 shows the shape of the suction pad 84. 10A is a cross-sectional view, FIG. 10B is a cross-sectional view showing a cross section orthogonal to FIG. 10A by 90 °, and FIG.
It is sectional drawing along the c 'line. The suction pad itself is formed of an elastic member such as rubber, and a screw member 88 having a flat cross section is inserted as a stopper into the elastic member such as rubber. By turning the screw member 88, the insertion depth of the plug changes, the cross-sectional area of the air flow path indicated by the arrow in FIG. 3B changes, and the suction strength can be easily adjusted.

In general, when the suction force is increased so that the color separation plate can be reliably taken out of the tray, the color separation plate is deformed upwardly in the hole of the pad, and the flatness of the film may be impaired. . If the flatness is impaired, the registration mark (usually a cross shape) will be distorted due to the registration of the separation between the colors written on the color separation, and the registration between the colors will not be accurate. I can no longer do it. According to this embodiment, the suction force can be easily and finely adjusted, so that when the mount and the color separation plate are taken out from the tray, they can be taken out reliably and without impairing the flatness.

Next, the details of the tape sticking unit provided on the Z table 20 will be described. As shown in FIG. 9, three tape application units are provided in the lateral direction of the Z table 20, and each unit can perform tape application at four locations. Actually, three positions corresponding to the size of the color separation plate are selected from the four positions. FIG.
As shown in FIG. 1, each unit holds a continuous tape 110, and a tape cassette 104 detachably provided on the Z table 20; a tape attaching head 102 provided corresponding to the opening 82; It has two claws 120, 122 which can be opened and closed up and down at predetermined intervals.
A tape is cut out from the continuous tape 110 with the leading end of the tape held therebetween, and a traveling body 106 that carries the tape piece to the head 102 and a rail 1 for traveling of the traveling body 106
08. The traveling body 106 reciprocates between the tape cassette 104 and the tape attaching head 102 along a rail 108 by an air cylinder (not shown). A cutter for cutting out a tape piece is provided in the tape cassette 104.

The operation of the tape sticking unit will be described with reference to FIG. The tape cassette 104 has a continuous tape 110 in which a tape for pasting is wound around an annular core in multiple rounds. The tape is preferably colored red so that no shadow is formed during exposure. The tape extracted from the continuous tape 110 is supplied to the roller pair 1 via the roller 112.
14. Here, the adhesive surface of the tape faces downward. Although not shown, a sensor for detecting the remaining amount of the continuous tape 110 is provided on the Z table 20,
The tape cassette 104 is provided with a dog for a sensor. Therefore, the tape cassette 104 can be easily removed from the Z table 20 for tape exchange and cutter exchange. Therefore, these can be easily exchanged. When setting the continuous tape 110, it is necessary to make the leading end of the tape slightly protrude from the roller pair 114. The claws 120 and 122 can sandwich the tape when closed and can straddle the roller pair 114 when opened. Roller pair 11
A cutter 116 that cuts the tape is provided at the end of 4. The distance between the claws 120 and 122 is the tape attaching head 1
It is set to be slightly longer than the length of 02. Roller pair 1

The configuration of the nail pieces 124 and 126 is shown in FIG. On the surfaces of the upper and lower claw pieces 124 and 126, a non-slip material 134 having sufficient friction to pull out the tape piece from the continuous tape is provided so that its surface becomes uneven. Further, a non-adhesive material 136 such as a fluororesin to which the adhesive surface of the tape is not adhered is provided on the surface of the nail piece 126 which is in contact with the adhesive surface of the lower tape.
Is applied so as to fill irregularities on the surface of the non-slip material. This ensures that the tape piece is sandwiched,
Delivery of the tape piece from the nail to the application head is performed smoothly.

In the initial state, as shown in FIG. 12 (a), the running body 106 is at the initial position on the tape cassette 104 side, the claw 120 is closed, and the leading end of the tape protruding from the roller pair 114 is removed. It is sandwiched. At this time, the nail 12
2 is open and has no tape.

Next, as shown in FIG. 12B, when the traveling body 106 is moved toward the head 102 and the pawl 122 straddles the roller pair 114, the traveling body 106 stops moving.
The claws 122 are closed, and the tape 110 is sandwiched. Running body 10
This position of No. 6 is a cutting position. After this, the cutter 11
6 descends and cuts the tape between the pawl 122 and the roller pair 114. Thereby, a tape piece corresponding to the length between the claws 120 and 122 is cut out from the tape cassette 104.

With the tape piece sandwiched between the claws 120 and 122, the traveling body 106 is further moved toward the head 102 as shown in FIG. The head 102
At this time, it is positioned above so as not to hinder the passage of the claws 120 and 122. The traveling body 10 right below the head 102
When 6 is moved, the movement of the traveling body 106 is stopped, and the head 102 descends. On the lower surface of the head 102, a large number of suction holes for sucking the tape are provided.
When 2 is lowered, the claws 120 and 122 are opened, and the tape piece is sucked to the lower surface of the head 102. At this time, in order to reliably transfer the tape piece from the claw to the head, the head descends below the position of the tape piece and presses the tape before the claw opens. Thereafter, the head 102 moves up and the traveling body 106
Returns to the position shown in FIG. 12A, and the supply of the tape piece to the next head is performed. Note that the lower surface of the head 102 is desirably formed of an elastic member such as rubber in order to securely attach the tape to the mount.

The operation of this embodiment will be described with reference to the flowcharts shown in FIGS. First, tray unit 1
At 6, the color separation plates for one item are set on the film trays 24 and 26 in a predetermined order, and the mounts corresponding to the mount trays 30 and 32 are set. As described above, the film tray has a size capable of holding the largest color separation (two-page spread in the case of newspaper) and a color separation plate.
In the case of only one page, the color separation plate is set on one side of the corresponding page side in the tray using the separator 40, and when the number of steps is 15 or less, the color separation plate is set in the corresponding area using the film presser 44. . A pin hole is provided in the backing sheet, a corresponding pin is provided in the backing tray, and the backing sheet is positioned with respect to the pin and set in the tray.

When an operation start is instructed by operating the key switch section 12, the contents of the tray are checked in step # 10. Here, the size and location of the color separation are determined. The result of the determination is used to determine the position of tape application in tape preparation and the like described later. In addition, the presence or absence of the pasted backing sheet in the plate discharge tray 32 is also detected, and a warning is issued if the pasted backing sheet remains in the plate discharge tray 32 when the backing sheet and the color separation plate are set in the tray. You.

In step # 12, the Z table 20 is lowered to the mount receiving position. The mount receiving position is the position of the Z table when transferring the mount from the trays 28 and 30 to the Z table 20. At this time, the pins for positioning the backing paper rise from the θ table 22.

Each row of the tape application units has four tape application positions and has an application head 102 at each position. Three heads 102 are selected according to the size of the color separation plate. The tape sticking unit cuts out a piece of tape from the continuous tape 110 of the tape cassette 104,
A piece of tape is supplied to these selected heads.
The head is holding the tape piece and waits for the tape to stick.

At step # 16, the backing tray 30 or 32 is inserted into the apparatus main body, and enters between the Z table 20 and the θ table. When the entry of the mount tray is completed, the vacuum device of the Z table 20 operates in step # 18, and the rear end of the mount is first attracted to the Z table 20 as shown in FIG. Here, even if a plurality of mounts are sucked, the second and subsequent sheets are peeled off by the function of the elastic member 64 at the rear end of the tray. At this time, the pins in the mount tray are lowered to be easily taken out of the mount and buried in the tray.

In step # 20, the Z table 20 is slightly moved up and down while only the rear end portion of the mount is attracted to the Z table 20. Thus, when a plurality of mounts are attracted to the Z table 20, even if the elastic members 64 cannot separate the mounts, the second and subsequent mounts are surely shaken down. It is adsorbed on the table 20.

In step # 22, the mount tray is ejected from the apparatus main body. At this time, as shown in FIG. 8B, the backing sheet is completely attracted to the Z table 20 by the pressing action of the roller 66.

Thereafter, the positioning pins in the mount tray rise again, and at step # 24, the Z table 20
Moves (falls) to the sensor position.

In step # 26, the .theta. Table 22 reads the identification mark of the backing sheet adsorbed on the Z table 20,
It is checked whether the back and front of the backing sheet and the backing pattern are correct. If the check result is correct, step # 28
, The vacuum device of the θ table 22 is operated, the Z table 20 is lowered to the lowest point, the vacuum device of the Z table 20 is turned off, and the mount is moved to the θ table 2.
2 on top. Thereby, the backing sheet is taken out from the backing tray and placed at a predetermined position on the θ table 22. The mounted mount is sucked by the vacuum device of the θ table 22 and fixed on the table.

If the check result is not correct, step # 52 is executed, and the board is discharged. Here, the tape application unit prepares the tape application in parallel with the above operation, that is, cuts out the tape and supplies the tape to the head. Is output. For this reason, it is possible to recognize that the check result is not normal by directly looking at the mount on which the tape piece is stuck.

In step # 30, the Z table 20 moves (ups) to the film receiving position. The film receiving position means that the film is transferred from the trays 24 and 26 to the Z table 20.
This is the position of the Z table at the time of transfer to.

In step # 32, the film tray 24 or 26 is inserted into the apparatus main body, and the Z table 20, θ
It enters between the tables 22. As in the case of the backing paper, the color separation plates are taken out of the tray in steps # 34 to # 38, and are pressed onto the Z table 20 by being pressed by the rollers 66 when the tray is withdrawn from the apparatus main body.

In step # 40, the Z table 20 descends to the sensor position. In step # 42, an optical sensor provided in the θ table 22 detects a registration mark of the color separation plate, checks a registration error of the film, and calculates a registration amount θ, x, y of the color separation plate. , Step # 4
In step 4, registration between the color plates is performed. Since the details of this registration are described in the above-mentioned Japanese Patent Application No. 3-120438, a detailed description will be omitted. The identification mark is used to check whether the color, front and back, pages, etc. of the separations are correct. If the check result is not correct, the color separations are returned to the film tray, and then the mount is discharged. Positioning (registering) is performed by rotating and moving the θ table 22.

In step # 46, the Z table 20 is lowered to the lowest point, and since the vacuum device of the θ table 22 is operating, the color separation plate is turned off by turning off the vacuum device of the Z table 20. To the mount on the θ table 22 and the color separation is
It is held down on the backing paper.

By this time, the claw 120 of the traveling body 106 as shown in FIG.
An operation of supplying a tape piece to each head 102 is performed by opening and closing 122, running the traveling body 106, performing a vacuum operation of the head 102, and the like. That is, the traveling body 106 is moved to the initial position, the claws 122 are closed, and the leading end of the tape is sandwiched.
The traveling body 106 is moved to the cutting position (FIG. 12B),
The claw 122 is closed, the tape is sandwiched, the tape is cut by the cutter 116 to form a tape piece, and the traveling body 106 is moved to the head position (FIG. 12C). And the head 10
2 is lowered, the vacuum device of the head is operated, the claws 120 and 122 are released, and the tape piece is attracted to the lower surface of the head 102. Thereafter, the traveling body 106 is returned to the initial position, and the same operation is repeated by the number of heads required for pasting.

After the Z table 20 is lowered to the lowest point in step # 48, the tape applying head 102 is lowered, and the tape piece is pressed onto the backing paper and the color separation plate. Head 102
After the vacuum operation is stopped, the color separation plate is attached to the mount by raising the head 102.

In step # 50, the mounting sheet positioning pin of the θ table 22 is lowered to be buried in the table.
The operation of the vacuum device of the θ table 22 is stopped. At this time, since the Z table 20 is located at the lowest point,
By activating the vacuum device of the table 20, the mount after the film is stuck can be transferred from the θ table 22 to the Z table 20 by suction.

In step # 52, the Z table 20 is raised to the plate discharging position. In step # 54, the plate discharging tray 32 is inserted into the apparatus main body, and enters between the Z table and the θ table.

By stopping the operation of the vacuum device of the Z table 20 in step # 56, the backing sheet that has been pasted into the plate discharge tray 32 can be collected. In step # 58, the plate discharge tray 32 retreats from between the Z table and the θ table, and the attachment of the film to one sheet of paper is completed. Here, a message is displayed on the display unit 14 when at least one backing sheet is discharged into the plate discharge tray 32 in order to indicate the plate dischargeable state.

Here, two sets of trays are prepared, and when one set is activated, the above-mentioned operation is automatically repeated until the mounts and films in the set tray are exhausted, and the process proceeds continuously. During that time, it is not possible to operate (pull out) the plate discharge tray as well as the tray of the set. However, if it is desired to take out one of the pasted sheets without waiting for the processing of all sheets to be completed, or to process a more urgent color separation plate, the key switch unit 12 is provided with an interrupt button. By pressing this, the operation can be stopped halfway. However, when the interrupt button is pressed, one sheet in process is accommodated in the plate discharge tray, and the operation is interrupted when the plate discharge tray returns. In this state, another set of trays can be operated, or the film in the set of trays can be removed, replaced with another one, and the set can be operated again. By pressing two keys in the order of activation and interruption, for example, five sheets of backing paper,
Even when the film is set, the operation is interrupted when one sheet of paper is finished, and the pasted sheets can be taken out one by one. Alternatively, the key switch unit 12 may be provided with a plate discharging key, and by pressing this key, the film or the mounting sheet that is being processed at that time may be forcibly discharged. At this time, the tape being prepared is also attached to the mount and collected.

As described above, according to the present embodiment, the mount and the film are automatically taken out from the tray simply by setting the mount and the color separation plate in the tray, and are registered and registered on the θ table. The color separation plate can be stuck on the backing paper by the tape sticking unit installed in the Z table, and a high-precision film can be stuck easily without imposing a burden on an operator.

The present invention is not limited to the above-described embodiment, but can be implemented with various modifications. For example, the mount may be directly placed on the θ table without being set in the tray. Further, although the decomposed plate is a negative film, it may be a positive film, and the object is a color photograph such as a newspaper. However, the present invention is not limited to this.

[0058]

According to the film sticking apparatus according to the present invention, when the mount and the color separation plate are automatically taken out from the tray, 2
Even if more than one mount and color separation plate are adsorbed, the second and subsequent sheets are peeled off by the elastic member, so only one sheet can be taken out of the tray without fail. By simply placing the film, the film is automatically stuck, so that a high-quality original film can be efficiently produced with less operator fatigue.
