Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color proof laminating apparatus for laminating a material to be laminated (hereinafter referred to as a mount) and a color material to calibrate a color of a multicolor printed matter.

[0002]

2. Description of the Related Art Generally, a proofing machine is used for color proofing a multicolor printed matter. However, since the proofing machine is large and requires a long working time, simple color proofing has recently been performed by hard copy. As one method of color proofing by hard copy, first, the original image is color-separated into four colors to produce each halftone film. On the other hand, the mount and the color material are laminated by a laminating device, and this is superposed on the halftone dot film and exposed. An image of a desired color is obtained by performing development processing after exposure. A color proof is obtained by sequentially repeating such steps for four color materials. Color proofing is performed by inspecting this color proof.

[0003]

In the color proofing method as described above, when the mount and the color material are laminated, they are conveyed while being sandwiched between a pair of heat rollers,
It adheres by heat and pressure. At this time, it is important to adjust the temperature of the heat roller, which is in contact with the color material, with high accuracy. Therefore, a temperature sensor that measures the temperature of the heat roller and a temperature adjustment circuit that adjusts the temperature based on the detection result of the temperature sensor are provided.

Here, in order to accurately measure the temperature of the surface of the heat roller, it is desirable that the temperature sensor is arranged in contact with the surface of the heat roller. Therefore, if a temperature sensor is provided in contact with the surface of the heat roller in a region where the coloring material and the backing sheet do not pass, the response to the temperature change deteriorates due to heat absorption when the coloring material passes, and the desired temperature is maintained accurately. Is difficult. In addition, if a temperature sensor is attached to the center of the heat roller surface in the axial direction so that the temperature of the place where the color material or the like always passes can be measured, the heat roller surface normally made of silicon rubber or the like will contact the sensor. This causes a problem that the portion of the heat roller is worn, and the color material and the mount are not laminated well in this portion.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a color proofing laminator capable of accurately measuring the temperature of a heat roller without adversely affecting the laminate and satisfactorily controlling the temperature. Another object of the present invention is to perform accurate temperature control and, even when the mount and the color material are wound around the heat roller, a temperature sensor in which the wound mount and the color material are in contact with the surface of the heat roller. It is an object of the present invention to provide a color proofing laminating apparatus that does not adversely affect the image quality.

Still another object of the present invention is to provide a color proof laminating apparatus capable of laminating uniformly over the entire width direction.

0 is connected to upper and lower temperature sensors 42 and 43 and halogen lamp heaters 36 and 37. General operation In this laminating apparatus, it is possible to set a program control mode when laminating the color material and the mount. When this program control mode is selected and the auto feed mode is selected, the mount paper or a laminated paper on which several color materials have been already laminated is inserted from the mount insertion tray 5 to automatically follow the laminating order. The color material is selected, and the roll-shaped color material is cut to a set length and sequentially laminated. Further, in the case of manual feeding in the program control mode, a mount or a laminated paper is inserted from the mount insertion tray 5, and a sheet-shaped color material is inserted from the color material insertion tray 4 according to the laminating order. The color material and the mount are laminated with the degree of overlap set by the program.

On the other hand, when the program control mode is not selected, lamination is performed for each color material according to the conditions set by the console panel. The outline of the laminating operation for the manual operation will be described. First,
When the mount is inserted from the mount insertion tray 5 into the laminating unit 2, the mount detection sensor 23 detects the mount insertion. Then, the mount transport unit 17 draws the mount into the laminating unit 2, and when the leading end of the mount is detected by the mount leading edge detection sensor 60, the feeding of the mount is temporarily stopped. Next, when a sheet-shaped color material is inserted from the color material insertion tray 4, this 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. When the front end of the color material is detected by the color material front end detection sensor 57, the feeding of the color material is once 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 temperature-controlled by the temperature adjusting circuit 130 to a predetermined temperature (for example, the upper heat roller 135 ° C. and the lower heat roller 82 ° C.). Both are laminated by passing the color material and the backing sheet between them. The laminated mount and the color material are guided below the apparatus along the discharge guide member 6 and onto the discharge tray 7.

In the automatic feed mode, when the mount 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 feeding position above the cutter device 11. Be done. Then, the roll-shaped coloring material is sent to the coloring material conveying section 16 of the laminating section 2 by operating the feeding device. The subsequent operation is the same, and when the roll-shaped color material reaches a predetermined length, the cutter device 11 is activated to cut the roll-shaped color material.

Further, when the small-sized color material and the backing sheet pass through the heat roller device 15 in the width direction, they are conveyed by one side reference, so that the reference side roller shaft may be lifted upward. In this case, the stabilizer rod 5
Since the opposite side is lifted by the torsional rigidity of 3, the roller shafts can always be positioned in parallel, and uniform lamination can be performed over the entire width direction.

After the color material is laminated on the mount as described above, the color material base paper is peeled off, and the film of the color and the laminated paper are brought into close contact with each other to perform exposure. Next, after peeling off the exposed cover film of the coloring material, it 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 repeated in the order of laminating to obtain a color proof. Control Operation The control operation will be described with reference to the flowcharts of FIGS.

First, the overall control process 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, step S1
Then, the initial processing is performed. In this initial processing, each part is moved to the initial position and the temperature of the heat roller device 15 is adjusted. Next, in step S2, origin reset processing is performed. In this origin reset process, 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 proceeds to step S3 and a standby process is performed. In this standby process, various laminating 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
In step 4, it is determined whether or not the program control mode is set as the operation mode in the standby process of step S3. When the program control mode is set, the timing of laminating the backing and the color material of each color (overlap condition)
Is automatically set according to the preset conditions,
Also, the laminating order is automatically performed in a preset order. In this case, the process proceeds to step S5, and i for determining which layer the color material to be laminated is “1”.
And When the program control mode is not 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 is set. If the auto feed mode is set, the process proceeds to step S7.
In step S7, a mount set process of setting the inserted mount at a predetermined position of the mount transport unit 17, and pulling out roll-shaped color material from a desired color material roll in the carriage 9 to a predetermined position of the color material transport unit 16. The roll color material setting process for setting is performed in parallel, and then the laminating process for laminating the mount and the color material is performed.

On the other hand, if the auto feed mode is not set, the program proceeds from step S6 to step S8. In step S8, a mount set process is performed to set the mount inserted from the mount insertion tray 5 at a predetermined position of the mount transport unit 17. Next, in step S9, the sheet-shaped 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, a mount and a sheet-shaped color material are supplied to the heat roller device 15 to perform a laminating process.

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 again whether or not the program control mode is set. If the program control mode is set, step S11 is performed.
Move to 12. In step S12, the i is "4".
It is determined whether or not If the laminating process has not been completed for the four color materials, this step S1
If NO is determined in step 2, the process proceeds to step S13. In step S13, i is incremented and x1 for setting the amount of displacement between the mount and the color material is decreased by d, and the process returns to step S6. The deviation between the mount and the color material will be described later. On the other hand, when the lamination is completed for all the color materials, YES is determined in step S12, and the process returns to step S3 to wait for the next process. If NO in step S11, step S11
Return from S11 to S3.

Next, the initial processing in step S1 of FIG. 9 will be described with reference to FIG. In this initial processing, initial setting is first 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 temperature adjustment 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. Wait for the temperature adjustment to complete, then the program will proceed to step S2.
The process proceeds from step 3 to step S24. In step S24, the completion of temperature adjustment is displayed on the display unit of the console panel 129. Next, in step S25, after waiting for the clear key to be pressed by the operator, the process proceeds to step S26. This step S25 is a process for moving to the next step after the operator surely confirms that the temperature has risen. In step S26, the temperature adjustment completion display that has been displayed on the display unit of the console panel 129 is erased, and the origin reset display, which is the next process, is performed. In this way, the initial processing ends.

Next, the origin reset process performed in step S2 of FIG. 9 will be described with reference to FIG. When confirming that the origin reset display is made in step S26 of the initial processing, the operator presses the start key to shift to the origin reset processing. In step S30, the input of this start key is waited for, and then step S31.
Move to. In step S31, the heat roller device 15 is controlled to a rotation speed for laminating at a speed higher than the standby speed. Then, in step S32, the color material feed clutch is turned on to rotate the color material transport roller 55 of the color material transport unit 16. In step S33, the timer T1 is started, and the length sensor 1 such as the encoder connected to the color material transport roller 55 in step S34 is also used.
Count 50 pulses. Next, in step S35, it is determined whether or not the count value c1 of the length sensor has become "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. From step S33
In step S36, the time T1 for 500 pulses of the length sensor is measured. In step S37, the color material feeding clutch is turned off to stop the rotation of the color material carrying roller 55. Next, in step S38, the count value c
The speed SP of the color material transport roller 55 is calculated from 1 and the timer time T1. Here, the color material transporting roller 55 and the mount sheet transporting roller 58 are driven by the same drive system, so that the speed of the mount sheet transporting roller 58 is the same as the color material transporting roller 55.
It becomes the same as the 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 rotational speed of the motor for lowering the upper heat roller 31. After waiting for both heat rollers 30 and 31 to nip, it transfers to step S42. In step S42, the timer T2 is stopped. Then, in step S43, the upper heat roller 30
Stops the descent of and reverses the motor rotation to raise it 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 transport roller 55 and the mount transport roller 58 thus determined, that is, the transport speed SP, and the time T2 required for the upper heat roller 30 to descend, the jam used in the subsequent processing. Calculate the required calculation time for detection. That is, step S4
5, the mount detection sensor 23 and the mount leading edge detection sensor 60
The distance N1 between and is divided by the transport speed SP to calculate the calculation time T3 when the mount is sent from the mount detection sensor 23 to the mount leading edge detection sensor 60. In step S46, when the sheet-shaped color material is sent from the color material detection sensor 22 to the color material tip detection sensor 57 by dividing the distance N2 from the color material detection sensor 22 to the color material tip detection sensor 57 by the transport speed SP. The calculation time T4 is calculated. Step S
In the case of 47, the mount front end detection sensor 60 to the discharge sensor 62
The distance N3 up to is divided by the transport speed SP to calculate a calculation time T5 when the mount and the color material are sent from the mount leading edge detection sensor 60 to the discharge sensor 62. Step S4
8, the color material tip detection sensor 57 to the heat roller device 15
In order to start lowering of the upper heat roller 31, the time T2 until the upper heat roller 30 nips obtained in steps S40 to S42 is further subtracted from the time obtained by dividing the distance N4 to the nip position by the transport speed SP. The calculation time T6 is calculated. Further, 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 mount sheet leading edge detection sensor 60 and the deviation amount x1 (see FIG. 18) between the mount and the end portion of the color material is added to the above It is divided by the transport speed SP to calculate a calculation time T11 for starting the sending of the color material so that the distance between the leading edge of the mount and the leading edge of the color material is x1. In this way, each calculation time is calculated, and the process shifts to the standby process.

In the standby process, various modes are set as described above, and keys are input to set conditions. Next, the processing of step S7 when the program control mode is set will be described. This step S7
The process of is executed when the auto feed mode is selected.

First, the mount setting process and the roll color material setting process shown in FIGS. 12 and 13 are executed. In the mount setting process, it is determined in step S55 whether the mount has been inserted from the mount tray 5. The insertion of the mount is performed by the mount detection sensor 23. When the mount is inserted, the process proceeds to step S56, the mount feed clutch is turned on, and the mount transport roll 58 is rotated. Next, in step S57, the timer T7 is started. In step S58, the timer T7 calculates the mount jam detection time T calculated in step S45.
It is judged whether or not 3 is exceeded. If the time T7 does not exceed the mount jam detection time T3, step S5
In step 9, it is determined whether or not the mount edge detection sensor 60 has detected the mount edge. Steps S58 and S59 until the sensor 60 detects the leading edge of the mount.
Is repeatedly executed. If the time T7 reaches the mount jam detection time T3 without the front end of the mount being detected, the process proceeds to error processing. When the leading edge of the mount is detected within the jam detection time T3, the process proceeds to step S60, the mount feed clutch is turned off, and the rotation of the mount transport roll 58 is stopped. As a result, the conveyance of the mount is stopped with the front end of the mount positioned on the sensor 60.

On the other hand, if the start key of the console panel 129 is pressed during the mount setting process, YES is determined in step S61 of FIG. 13, and the process proceeds to step S62. In this case, the mount setting process and the roll color material setting process are performed in parallel. In step S62, the movement of the carriage 9 is started first. In this case, the motor 82 is rotated to drive the drive mechanism 8
When the clutch 89 of 0 is turned on, the feeding mechanism 1
The clutch 104 of 00 is turned off. As a result, the rotation of the motor 82 is transmitted to the bracket 81 of the carriage 9 via each sprocket and the chain, and the carriage 9
Moves forward from the origin position. Here, since i = 1 in the laminating 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 done. Cyan colorant roll 10
If a is at the desired position, the process proceeds to step S64, the clutch 89 is turned off, and the movement of the carriage 9 is stopped.

Next, in step S65, driving of the color material transport roll 55 is started. In this state, in step S66, the roll-shaped coloring material having a predetermined length is fed by the feeding mechanism 100. Next, in step S67, it is determined whether or not the leading edge of the roll-shaped coloring material has been detected by the coloring material leading edge detection sensor 57. When it is detected, the process proceeds from step S67 to step S68, and the color material transport by the color material transport roll 55 is stopped.

Now, the process of feeding 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 fed by a predetermined length. If the paper has been sent for a predetermined length, the process proceeds to step S71. In step S71, the cutter device 11 is activated to cut the roll-shaped color material. Next, in step S72, the motor 82 is rotated in the reverse direction. Then, in step S73, the roll-shaped coloring material having a predetermined length is sent back. That is, the roll-shaped color material is fed back until the tip reaches the roll nip position in the carriage 9,
If it is sent back, the process proceeds to step S74. The amount of feeding back is performed by detecting the number of rotations of the feeding roller device 106 by an encoder or the like, for example. In step S74, the motor 82 and the cutter device 1
Turn off the motor of 1.

In this way, the front end of the mount is temporarily stopped at the position of the mount front end detection sensor 60, and the roll-shaped color material is also stopped at the position of the color material front end detection sensor 57. On the other hand, when the auto feed mode is not set, the mount and the color material are set by the processing of steps S8 and S9 in FIG. The control flow in this case is shown in FIG.

First, in step S80, it is detected whether or not the mount is inserted. The standby process is executed until the mount is inserted. When the insertion of the mount is detected by the mount detection sensor 23, steps S80 to S81.
Move to. In step S81, the mount feed clutch is turned on to rotate the mount transport roll 58. Further, the timer T7 is started in step S82. The processes of steps S83 and S84 are similar to the processes of steps S58 and S59 in FIG. 12, and the jam of the mount is detected. When the leading edge of the mount is detected, steps S84 to S85
Then, the mount feeding clutch is turned off and the mount conveying roller 58 is stopped.

Next, in step S86, the color material detection sensor 22 determines whether or not a sheet-shaped color material has been inserted from the color material insertion tray 4. If no color material has been inserted, standby processing is executed. When it is detected that the color material is inserted, the process proceeds from step S86 to step S87. In step S87, the process waits until the start key on the console panel 129 is pressed. This step S87
The process is for the operator to set the color material after confirming that the mount is inserted and set. If the start key is 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 transported to the heat roller device 15 side by the color material transport roller 55.

Next, in step S89, the timer T8 is started. Next, in step S90, it is determined whether or not the time T8 exceeds the calculation time T4 for detecting the color material jam. If not exceeded, step S91
Move to. In step S91, it is determined whether the front end of the color material is detected by the color material front end detection sensor 57. Steps S90 and S91 are repeatedly executed until the leading edge of the color material is detected. If the time T8 reaches the color material jam detection time T4 before the leading edge of the color material is detected, the process proceeds from step S90 to error processing.
When the color material is detected within the jam detection time T4, the process proceeds to step S92, 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 leading edge detection sensor 60, and the sheet-shaped color material is temporarily stopped at the position of the color material leading edge detection sensor 57. Next, the laminating process in steps S7 and S10 will be described with reference to FIG. As described above, the roll-shaped color material or the sheet-shaped color material is stopped at the position of the color material tip detection sensor 57, and the mount is stopped at the position of the mount tip detection sensor 60, and then the laminating process is executed. .. In this laminating process, first, in step S100, the heat roller device 15 is rotated at the laminating speed. Further, in step S101, the timer T9 is started. Then, in step S102, it is determined whether or not the time T9 has reached 2 seconds. This time T9 is for ensuring a time until the heat roller device reaches a stable laminating speed when the motor for driving the heat roller is changed to the laminating speed. When the time T9 becomes 2 seconds, the process proceeds to step S103. In step S103, the mount feed clutch is turned on to rotate the mount transport roller 58. As a result, 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 rotated to convey the color material to the heat roller device 15 side. In this manner, by feeding the color material a predetermined time after the start of the supply of the mount material, as shown in FIG. 18, the cyan color material 14 of the first layer is displaced by a distance x1 from the front end of the mount material 140.
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 the time T10 reaches 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 set to the lower heat roller 3
It is determined whether or not the nip is made to 1. When the nip has occurred, the process proceeds to step S110, and the lowering of the upper heat roller 30 is stopped.

Next, in step S111, time T10
Determines whether the calculation time T5 for detecting wrapping has been exceeded. If the determination in step S111 is yes, the process moves to step S112. In step S112, it is determined whether the discharge sensor 62 has detected the leading edge of the mount. If the leading edge of the mount is not detected, step S
111 and step S112 are repeatedly executed. Then, when the leading edge of the mount is not detected by the discharge sensor 62 during the wrap detection time T5, it is determined that the mount and the color material have been wound around the heat roller, and thus step S1.
The processing shifts from 11 to error processing. Winding detection time T5
If the front end of the mount is detected by the discharge sensor 62, the process proceeds to step S113. Step S11
At 3, it is determined whether the discharge sensor 62 is turned off.
That is, it is determined whether the mount and the color material have passed over the discharge sensor 62. When passing, step S11
4, the upper heat roller 30 is raised to the origin position. Next, in step S115, the heat roller device 15 is controlled to the standby speed. Then, in step S116, both the color material feed clutch and the mount paper feed clutch are turned off, and the rotation of the transport rollers 55 and 58 is stopped.

When the laminating process is completed as described above, it is determined in step S11 of FIG. 9 whether the program control mode is set. When the program control mode is set and the laminating process for all the color materials is not completed, the step S1 through the step S12 are followed by the step S1.
Move to 3. In this step S13, i is incremented to select the next color material, and x1, which is the amount of deviation between the mount and the color material, is set to (x1-d), and the process returns to step S6. Hereinafter, similar processing is repeatedly executed for the second layer, the third layer, and the fourth layer.

In the program control mode as described above, as shown in FIG.
41, magenta color material 142, yellow color material 143, and 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 it. Therefore, during the development process, the coloring material is removed and the adhesive remaining on the mount is covered with the coloring material in the upper layer.
The adhesive 140 that remains may cause the mount 140 to move to the upper heat roller 30.
It is prevented from being wrapped around.

Next, the error processing will be described with reference to FIG. In this error processing, all of the drive system are once 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 cancels 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 before each use of the apparatus, and based on the measurement result,
Since the time for carrying control such as jam detection at the time of feeding the color material and the mount is calculated, when the jam of the color material and the mount occurs, it can be accurately and quickly detected. Further, the ends of the mount and the coloring material can be accurately aligned with desired positions, and accurate lamination can be performed. In addition, even if the color material and the backing paper are wound around the heat roller, this winding can be detected immediately.
Since the winding area can be reduced, the cleaning of the heat roller can be done in the minimum area, and the device can be quickly restored.

Further, since the measurement is performed before each use of the apparatus, it is possible to perform accurate control by following the frequency fluctuation and voltage fluctuation of the power source.

Even the desired temperature can be adjusted quickly. Further, since the temperature measuring means is provided in contact with the surface of the heat roller through which the area other than the pattern area of the color material passes, even if the heat roller is worn by the temperature measuring means, the pattern is not adversely affected. ..
