2. Description of the Related Art In general, when performing color proofing of a multicolor print, a proofing machine is used. In this case, accurate color proofing can be performed, but since the proofing machine itself is large and the work time is long, simple color proofing using hard copy has recently been performed.

In color proofing by hard copy, a so-called color pre-proof method, an original image is first separated into four colors to produce halftone films of yellow, magenta, cyan and black. On the other hand, a mount and a color material are laminated by a laminating apparatus, a halftone dot film is superposed on the mount on which the color material is laminated and exposed, and then a developing process is performed. A color proof is obtained by sequentially repeating such an operation for each color, and color proofing is performed by inspecting the color proof.

[0004] The laminating apparatus in the color proofing method has a supply board for the mount and the color material, a transport section for transporting the mount and the color material, and a laminating section for laminating these. In the laminating section, the mount and the color material transported by each transport section are sandwiched between the heat roller pairs and laminated while being transported.

In addition, the lamination order cannot be arbitrarily selected. The publication also discloses that a color material supply stand is provided independently for each color. However, when a color material supply stand is provided for each color with the configuration described in this publication, each color material supply stand is provided. A transport system is required for each supply table, and the structure becomes very complicated.

Further, in the apparatus disclosed in the above-mentioned publication, since the color material having a predetermined length set in advance is used, the size of the color material that can be used is limited, and the size of the color material can be limited according to various conditions. Inability to respond flexibly. SUMMARY OF THE INVENTION An object of the present invention is to provide a color proofing laminating apparatus that can automatically supply a plurality of coloring materials with a simple configuration and can improve work efficiency.

0 is connected to upper and lower temperature sensors 42 and 43 and halogen lamp heaters 36 and 37. Outline operation In this laminating apparatus, it is possible to set a program control mode when laminating a color material and a mount. When this program control mode is selected and the auto feed mode is selected, the backing paper or the laminated paper on which some color materials are already laminated is inserted from the backing paper insertion tray 5 to automatically perform the lamination order. A color material is selected, and a roll-shaped color material is cut into a set length and sequentially laminated. In the case of manual feeding in the program control mode, a backing sheet or laminated paper is inserted from the backing sheet insertion tray 5 and a sheet-like coloring material is inserted from the coloring material insertion tray 4 according to the lamination order, so that each color is inserted. The color material and the backing sheet are laminated according to the degree of overlap set in the program.

On the other hand, when the program control mode is not selected, lamination is performed according to the conditions set by the console panel for each color material. The outline of the laminating operation for the manual operation will be described. First,
When the backing sheet is inserted from the backing sheet insertion tray 5 into the laminating unit 2, the backing sheet detection sensor 23 detects the insertion of the backing sheet. Then, the backing sheet is drawn into the laminating section 2 by the backing sheet transport section 17, and once the leading end of the backing sheet is detected by the backing sheet detecting sensor 60, the feeding of the backing sheet is temporarily stopped. Next, when a sheet-like color material is inserted from the color material insertion tray 4, the color material is detected by the color material detection sensor 22. As a result, the color material transport unit 16 operates, and the inserted color material is drawn into the laminating unit 2. Then, when the leading edge of the coloring material is detected by the coloring material leading edge detection sensor 57, the feeding of the coloring material is temporarily stopped. From this state, the mount and the color material are sent to the heat roller device 15 under the conditions set by the console panel or the like. Heat roller device 1
5, the upper heat roller 30 and the lower heat roller 31 are adjusted to a predetermined temperature (for example, the upper heat roller 135 ° C. and the lower heat roller 82 ° C.) by the temperature adjustment circuit 130. The two are laminated by passing the color material and the backing sheet between them. The laminated mount and coloring material are guided below the apparatus along the discharge guide member 6 and guided on the discharge tray 7.

In the auto feed mode, when the backing sheet is inserted and the start key on the console panel is pressed in the same manner as described above, the carriage 9 moves, and the desired color material roller moves to the supply position above the cutter device 11. Can be Then, the roll-shaped color material is sent to the color material transport unit 16 of the laminating unit 2 by operating the feeding device. The subsequent operation is the same. When the roll-shaped color material has reached a predetermined length, the cutter device 11 operates to cut the roll-shaped color material.

Further, when the small-sized color material and the backing paper pass through the heat roller device 15 in the width direction, they are conveyed on one side basis, so that the reference side roller shaft may be lifted upward. In this case, the stabilizer rod 5
Since the opposite side is also lifted by the torsional rigidity of No. 3, the roller shaft can always be positioned in parallel, and uniform lamination can be performed over the entire area in the width direction.

After laminating the color material on the backing paper as described above, the cover film of the color material is peeled off, and the exposure device is exposed.
The color separation film for the color plate and the laminated paper are brought into close contact with each other to perform exposure. Next, the exposed color material is inserted into a developing device to obtain an image of a desired color (for example, cyan).
In this way, the above-described processing is sequentially repeated in the order of lamination to obtain a color proof. Control Operation The control operation will be described with reference to the flowcharts of FIGS.

First, the overall control processing will be described with reference to the flowchart of FIG. When the start switch of the device is turned on, the program starts, and first, in step S1.
Then, an initial process is performed. In this initial processing, each part is moved to an initial position, and the temperature of the heat roller device 15 is adjusted. Next, in step S2, an origin reset process is performed. In the origin reset processing, the transport speed of the transport system is calculated, and the time required for the color material and the mount to be transported in a predetermined section is calculated. When these processes are completed, the process shifts to step S3 to perform a standby process. In this standby process, various lamination conditions and operation modes are set by key input from the console panel.

When the standby process is completed and the start key is pressed, the program proceeds to step S4. Step S
At 4, it is determined whether or not the program control mode has been set as the operation mode in the standby process of step S3. When the program control mode is set, the timing of lamination between the mount and the color material of each color (overlapping condition)
Is automatically set according to preset conditions,
The laminating order is automatically performed in a preset order. In this case, the process proceeds to step S5, and i for determining the layer number of the color material to be laminated is set to “1”.
And If the program control mode has not been set, the process of step S5 is skipped, and the process proceeds to step S6.

In step S6, it is determined whether the auto feed mode has been set. If the automatic feed mode has been set, the process proceeds to step S7.
In step S7, a backing sheet setting process for setting the inserted backing sheet at a predetermined position of the backing sheet transport unit 17 and pulling out a roll-shaped color material from a desired color material roll in the carriage 9 to a predetermined position of the coloring material transport unit 16 The roll color material setting process for setting is performed in parallel, and thereafter, a lamination process for laminating the mount and the color material is performed.

On the other hand, when the auto feed mode is not set, the program proceeds from step S6 to step S8. In step S8, a backing sheet setting process for setting the backing sheet inserted from the backing sheet insertion tray 5 to a predetermined position of the backing sheet transport unit 17 is performed. Next, in step S9, the sheet color material inserted from the color material insertion tray 4 is
A color material setting process for setting the color material at a predetermined position of the color material transport unit 16 is performed. Next, in step S10, the mounting material and the sheet-like coloring material are supplied to the heat roller device 15, and a laminating process is performed.

When the laminating process in step S7 or the laminating process in step S10 is completed, the process proceeds to step S11. In step S11, it is determined whether or not the program control mode is set again. If the program control mode is set, step S11 is executed.
It moves to 12. In step S12, i is “4”.
It is determined whether or not it has become. If the lamination process has not been completed for the four color materials, this step S1
It is determined as NO in 2 and the process proceeds to step S13. In step S13, i is incremented, and x1 for setting the shift amount between the mount and the colorant is reduced by d, and the process returns to step S6. The displacement between the mount and the color material will be described later. On the other hand, if the lamination has been completed for all the color materials, YES is determined in the step S12, and the process returns to the step S3 to wait for the next process. If NO is determined in the step S11, the process proceeds to the step S11.
The process returns from step 11 to S3.

Next, the initial processing in step S1 of FIG. 9 will be described with reference to FIG. In this initial processing, first, initial settings are made in step S20. In this initial setting, processing such as moving the carriage 9 to the home position is performed. Next, in step S21, the rotation of the heat roller device 15 is started at a standby speed lower than the rotation speed during lamination. Then, in step S22, the temperature adjustment circuit 130 of the control unit 120 starts adjusting the temperature of the heat roller device 15. In step S23, it is determined whether the temperature adjustment has been completed. That is, it is determined whether the temperature of the upper heat roller 30 has reached 135 ° C. and the temperature of the lower heat roller 31 has reached 82 ° C. After the completion of the temperature adjustment, the program proceeds to step S2.
Then, control goes from step 3 to step S24. In step S24, the completion of the temperature adjustment is displayed on the display of console panel 129. Next, in step S25, the process proceeds to step S26 after waiting for the operator to press the clear key. This step S25 is a process for moving to the next step after the operator confirms that the temperature has risen without fail. In step S26, the temperature adjustment completion display previously displayed on the display unit of the console panel 129 is erased, and the origin reset display, which is the next process, is performed. Thus, the initial processing is completed.

Next, the origin reset processing performed in step S2 of FIG. 9 will be described with reference to FIG. When confirming that the origin reset display has been made in step S26 of the initial process, the operator presses the start key to shift to the origin reset process. In step S30, the process waits for the start key to be input, and in step S31
Move to In step S31, the rotation speed of the heat roller device 15 is controlled to be higher than the standby speed when the lamination is performed. In step S32, the color material feed clutch is turned on, and the color material transport roller 55 of the color material transport unit 16 is rotated. In step S33, the timer T1 is started, and in step S34, the length sensor 1 such as an encoder connected to the color material transporting roller 55 is used.
Count 50 pulses. Next, in step S35, it is determined whether or not the count value c1 of the length sensor has reached "500". After waiting for the count value c1 to reach "500", the process proceeds to step S36, and the timer T1 is stopped in step S36. This step S33 ~
In step S36, a time T1 for 500 pulses of the length sensor is measured. In step S37, the color material feed clutch is turned off to stop the rotation of the color material transport roller 55. Next, in step S38, the count value c
The speed SP of the color material conveying roller 55 is calculated based on 1 and the timer time T1. Here, the color material transporting roller 55 and the mount material transporting roller 58 are driven by the same drive system.
Speed SP.

Next, in step S39, the upper heat roller 30 is moved to the lower heat roller 31 side. At the same time, the timer T2 is started in step S40. In step S41, it is determined whether the upper heat roller 30 and the lower heat roller 31 have nipped. The nip between the heat rollers 30 and 31 is determined by the number of rotations of a motor for lowering the upper heat roller 31. After waiting for both heat rollers 30, 31 to nip, the process proceeds to step S42. In step S42, the timer T2 is stopped. Then, in step S43, the upper heat roller 30
Is stopped and the rotation of the motor is reversed to ascend to the origin position. Then, in step S44, the rotation speed of the heat roller device 15 is controlled to the standby speed.

From the speeds of the color material transporting roller 55 and the base paper transporting roller 58 obtained as described above, ie, the transporting speed SP, and the time T2 required for the lowering of the upper heat roller 30, the jam used in the subsequent processing is determined. The calculation time required for detection and the like is calculated. That is, step S4
5, the backing sheet detection sensor 23 and the backing sheet edge detection sensor 60
Is divided by the transport speed SP to calculate a calculation time T3 when the backing sheet is sent from the backing sheet detection sensor 23 to the backing sheet front end detection sensor 60. In step S46, when the distance N2 from the color material detection sensor 22 to the color material tip detection sensor 57 is divided by the transport speed SP, and the sheet-like color material is sent from the color material detection sensor 22 to the color material tip detection sensor 57 The calculation time T4 is calculated. Step S
At 47, the sheet-mounting-edge detection sensor 60 switches the discharge sensor 62
Is divided by the transport speed SP to calculate a calculation time T5 when the mount and the color material are fed from the mount leading edge detection sensor 60 to the discharge sensor 62. Step S4
8, the color material leading edge detection sensor 57 outputs the heat roller device 15
Is subtracted from the time obtained by dividing the distance N4 to the nip position by the transport speed SP by the time T2 until the upper heat roller 30 nip obtained in steps S40 to S42 is started. The calculation time T6 is calculated. In step S49, the heat rollers 30, 3
The sum of the difference α between the distance from the nip position N of No. 1 to the color material leading edge detection sensor 57 and the backing edge detection sensor 60 and the displacement x1 (see FIG. 18) between the backing material and the edge of the coloring material. The calculation time T11 is calculated by dividing by the transport speed SP and starting the color material feeding to set the distance between the top of the mount and the top of the color material to x1. In this way, each calculation time is calculated, and the process proceeds to the standby process.

In the standby process, various modes are set as described above, and key input for setting conditions is performed. Next, the processing in step S7 when the program control mode is set will be described. This step S7
Is executed when the auto feed mode is selected.

First, the backing sheet setting processing and the roll color material setting processing shown in FIGS. 12 and 13 are executed. In the backing sheet setting process, it is determined whether or not a backing sheet has been inserted from the backing tray 5 in step S55. The insertion of the mount is performed by the mount detection sensor 23. If the backing sheet has been inserted, the process proceeds to step S56, where the backing sheet feeding clutch is turned on to rotate the backing sheet transport roller 58. Next, in step S57, the timer T7 is started. In step S58, the timer T7 calculates the calculation time T for the mount jam detection calculated in step S45.
It is determined whether the number does not exceed three. If the time T7 does not exceed the mount jam detection time T3, step S5
Then, it is determined whether or not the leading edge of the backing sheet is detected by the backing sheet leading edge detection sensor 60. Steps S58 and S59 until the leading edge of the mount is detected by the sensor 60.
Is repeatedly executed. If the time T7 is equal to the mount jam detection time T3 without detecting the mount end, the process proceeds to error processing. If the leading end of the mount is detected within the jam detection time T3, the process proceeds to step S60, where the mount feed clutch is turned off, and the rotation of the mount transport roller 58 is stopped. Thus, the conveyance of the mount is stopped in a state where the leading end of the mount is positioned at the sensor 60.

On the other hand, if the start key of the console panel 129 is depressed while the mount setting process is being performed, “YES” is determined in the step S61 of FIG. 13, and the process shifts to a step S62. In this case, the mount setting process and the roll color material setting process are performed in parallel. In step S62, first, the movement of the carriage 9 is started. In this case, the motor 82 is rotated, and the driving mechanism 8 is rotated.
0 clutch 89 is turned on, and the delivery mechanism 1
00 is turned off. Thus, the rotation of the motor 82 is transmitted to the bracket 81 of the carriage 9 via each sprocket and chain, and
Moves forward from the origin position. Here, since i = 1 in the lamination process of the first layer, the cyan color material roll 10a of the first layer is moved to the supply position, that is, the position immediately above the cutter device 11 in step S63. It is determined whether or not it has been made. Cyan color material roll 10
If a has reached the desired position, the flow shifts to step S64 to turn off the clutch 89, thereby stopping the movement of the carriage 9.

[0050] Next, in step S65, the coloring material transport Russia
The driving of the roller 55 is started. In this state, step S66
Then, the feeding mechanism 100 feeds a roll-shaped color material of a predetermined length. Next, in step S67, it is determined whether or not the leading edge of the roll-shaped coloring material is detected by the coloring material leading edge detection sensor 57. If it is detected, the process proceeds from step S67 to step S68, and the color material transport by the color material transport roller 55 is stopped.

Here, the process of sending out the roll-shaped color material in step S66 will be described in detail with reference to FIG.
In FIG. 14, in step S70, it is determined whether or not the roll-shaped color material has been sent out by a predetermined length. When the predetermined length has been sent, the process proceeds to step S71. In step S71, the cutter device 11 is operated to cut the roll-shaped color material. Next, in step S72, the motor 82 is rotated in the reverse direction. Then, in step S73, a predetermined length of the roll-shaped color material is fed back. That is, it is fed back until the leading end of the roll-shaped coloring material reaches the roll nip position in the carriage 9,
If it has been returned, the process moves to step S74. The feed-back amount is determined, for example, by detecting the rotation speed of the feed roller device 106 using an encoder or the like. In step S74, the motor 82 and the cutter device 1
Turn off motor No. 1.

In this manner, the mount is temporarily stopped at the position of the mount-edge detecting sensor 60, and the roll-shaped color material is also temporarily stopped at the position of the color-material detect sensor 57. On the other hand, when the auto feed mode is not set, the mount and the color material are set by the processes of steps S8 and S9 in FIG. FIG. 15 shows a control flow in this case.

First, in step S 80, it is detected whether or not the mount has been inserted. The standby process is executed until the mount is inserted. When the insertion of the backing sheet is detected by the backing sheet detecting sensor 23, the steps S80 to S8 are performed.
Move to 1. In step S81, the backing paper feed clutch is turned on to rotate the backing paper conveyance roller 58. In step S82, the timer T7 is started.
The processing in steps S83 and S84 is the same as that in FIG.
In step S58 and step S59, the paper jam detection is performed. When the leading end of the backing paper is detected, steps S84 to S8 are performed.
Then, the program goes to 5 to turn off the mount feed clutch and stop the mount transport roller 58.

In step S86, the color material detection sensor 22 determines whether a sheet-like color material has been inserted from the color material insertion tray 4. If no color material has been inserted, a standby process is executed. When it is detected that the color material has been inserted, the process proceeds from step S86 to step S87. In the step S87, the process waits until the start key of the console panel 129 is pressed. This step S87
Is to set the color material after the operator confirms that the mount has been inserted and set. If the start key has been pressed, step S88
Move to In step S88, the color material feed clutch is turned on to rotate the color material transport roller 55. As a result, the sheet-shaped color material is conveyed by the color material conveyance roller 55 to the heat roller device 15 side.

Next, in step S89, the timer T8 is started. Next, in step S90, it is determined whether or not the time T8 has exceeded the calculation time T4 for detecting color material jam. If not exceeded, step S91
Move to In step S91, it is determined whether or not the leading end of the coloring material is detected by the leading edge detecting sensor 57. Steps S90 and S91 are repeatedly executed until the leading end of the color material is detected. If the time T8 becomes the color material jam detection time T4 before the leading end of the color material is detected, the process proceeds from step S90 to error processing.
If the color material is detected within the jam detection time T4, the process proceeds to step S92, where the color material feed clutch is turned off, and the rotation of the color material transport roller 55 is stopped.

In this way, the mount is temporarily stopped at the position of the mount-edge detecting sensor 60, and the sheet-like color material is temporarily stopped at the position of the color-material-end detecting sensor 57. Next, the laminating process in steps S7 and S10 will be described with reference to FIG. As described above, the laminating process is performed after the roll-shaped color material or the sheet-shaped color material is stopped at the position of the color material leading edge detection sensor 57 and the mount is stopped at the position of the mount material leading edge detection sensor 60. . In the laminating process, first, the heat roller device 15 is rotated at a laminating speed in step S100. In step S101, the timer T9 is started. Then, in a step S102, it is determined whether or not the time T9 has reached 2 seconds. This time T9 is for securing a time until the heat roller device reaches a stable laminating speed when the motor for driving the heat roller is shifted to the laminating speed. When the time T9 has reached 2 seconds, the flow shifts to step S103. In step S103, the backing paper feed clutch is turned on to rotate the backing paper conveyance roller 58. Thereby, the mount is supplied to the heat roller device 15 side. In the heater 104, the timer T10 is started. In step S105, it is determined whether the time T10 has reached the calculation time T11 for starting the color material feeding. After waiting for the time T10 to reach the color material feeding start time T11, the process proceeds to step S106. In step S106, the color material feed clutch is turned on, and the color material transport roller 55 is turned on.
Is rotated to convey the color material to the heat roller device 15 side. In this manner, by sending the color material a predetermined time after the start of the supply of the mount, the first color cyan material 14 of the first layer is shifted from the leading end of the mount 140 by the distance x1 as shown in FIG.
1 will be laminated.

Next, in step S107, it is determined whether or not the time T10 has reached the calculation time for starting the lowering of the upper heat roller 30. After waiting for the time T10 to reach the time T6, the process proceeds to step S108. Step S10
At 8, the lowering of the upper heat roller 30 is started. Next, in step S109, the upper heat roller 30 is
It is determined whether or not nip is performed at 1. If the nip occurs, the process proceeds to step S110, and the lowering of the upper heat roller 30 is stopped.

Next, at step S111, time T10
Is not longer than the calculation time T5 for detecting winding. If the determination in step S111 is YES, the process moves to step S112. In step S112, it is determined whether or not the discharge sensor 62 has detected the leading end of the mount. If the leading end of the backing sheet is not detected, step S
111 and step S112 are repeatedly executed. If the leading end of the mount is not detected by the discharge sensor 62 during the winding detection time T5, it is determined that the mount and the color material have wrapped around the heat roller.
Then, the process proceeds from step 11 to error processing. Winding detection time T5
If the leading end of the backing paper is detected by the discharge sensor 62, the process proceeds to step S113. Step S11
In 3, it is determined whether or not the discharge sensor 62 has been turned off.
That is, it is determined whether or not the mount and the color material have passed over the discharge sensor 62. If it has passed, step S11
Then, the process goes to 4 to raise the upper heat roller 30 to the origin position. Next, in step S115, the heat roller device 15 is controlled to the standby speed. In step S116, both the color material feed clutch and the backing paper feed clutch are turned off, and the rotation of each of the transport rollers 55 and 58 is stopped.

When the lamination process has been completed as described above, it is determined in step S11 in FIG. 9 whether or not the program control mode has been set. If the program control mode has been set and the lamination process has not been completed for all the color materials, the process proceeds from step S11 to step S12 via step S12.
Move to 3. In this step S13, i is incremented in order to select the next color material, and x1, which is the shift amount between the mount and the color material, is set to (x1-d), and the process returns to step S6. Hereinafter, the same processing is repeatedly executed for the second, third, and fourth layers.

In such a program control mode, as shown in FIG.
The color material 41, the magenta color material 142, the yellow color material 143, and the black color material 144 are respectively shifted by a distance d, and the lower color material is laminated so that the upper color material covers the lower color material. For this reason, at the time of the development processing, the coloring material is removed and the adhesive remaining on the backing paper is covered by the coloring material of the upper layer,
The adhesive 140 causes the backing paper 140 to move the upper heat roller 30
Is prevented from winding around.

Next, error processing will be described with reference to FIG. In this error processing, all the drive systems are temporarily turned off in step S120. And step S
At 121, an error is displayed on the display unit of the console panel 129. Then, when the operator resets the cause of the error and presses the power reset key, the process proceeds from step S122 to the initial process.

In such an apparatus, the conveying speed of the color material and the mount is performed every time the apparatus is used, and based on the measurement results,
Since the calculation of the time for the conveyance control such as the detection of the jam when the color material and the mount is fed, the jam of the color material and the mount can be accurately and quickly detected when the jam occurs. In addition, the ends of the mount and the coloring material can be accurately adjusted to desired positions, and accurate lamination can be performed. In addition, even when the coloring material and the backing material are wound around the heat roller, this winding can be detected immediately,
Since the wrapping area can be reduced, cleaning of the heat roller can be minimized, and the apparatus can be quickly recovered.

Further, since the measurement is performed before each use of the apparatus, accurate control can be performed by following the frequency fluctuation and voltage fluctuation of the power supply.
