  The present invention relates to a cutting control device for a printing press suitable for cutting a printed web at a predetermined position.And cutting assist deviceAbout.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in a rotary printing machine or the like, when a web is printed and then cut in the width direction of the web, there is provided a web cutting control device that controls a cutting position so as not to cause a cutting shift in the web flow direction. (For example, refer to Patent Document 1).
As shown in FIG. 5, the web 1 is transported from the paper supply unit 51 to the printing unit 53 via the guide roller group 52, and a pattern is printed on the web 1 by the printing unit 53. Thereafter, the web 1 is dried by the dryer unit 54, conveyed to the folding machine 56 through the web path unit 55, and cut in the web 1 width direction by the saw cylinder 60. At this time, the cutting control device functions to control the cutting position of the web 1 so as to cut the web 1 at a predetermined position.
[0003]
As shown in FIG. 6, the printing unit 53 normally prints the pattern 3 on the web 1, and marks are printed on portions other than the pattern 3. This mark is detected by the mark detector 57, and the control unit 62 shown in FIG. 5 detects the detection signal from the mark detector 57 and the reference pulse from the encoder 61 that rotates in synchronization with the saw barrel 60 of the folding machine 56. Based on the above, the motor 58 is driven and the compensator roller 59 is moved up and down so that the timing at which the web 1 is cut by the saw cylinder 60 and the timing at which the mark is detected by the mark detector 57 coincide with each other. Move in the direction. Thereby, the tension applied to the web 1 can be finely adjusted, that is, the web 1 can be expanded and contracted in the flow direction of the web 1, so that the cutting position of the printed matter can be held at a fixed position.

[Problems to be solved by the invention]
Incidentally, for example, as shown in FIG. 6, the mark 2 is printed between the pattern 3 and the pattern 3 printed on the web 1 and in the vicinity of the end of the web 1. Therefore, in this case, the mark detector 57 may be fixedly installed at the position where the mark 2 passes through the detection range of the mark detector 57 at the end of the web 1 on which the mark 2 is printed.
[0006]
However, as shown in FIG. 7A, when the mark 2 is printed near the center of the width on the web 1 and the mark 2 does not exist within the detection range of the mark detector 57, Since the mark detector 57 fixedly installed at the position indicated by the dotted line in FIG. 7A cannot detect the mark 2, as indicated by the solid line in FIG. 7A, within the detection range of the mark detector 57. It is necessary to move the mark detector 57 in the web 1 width direction to the position where the mark 2 exists. In this case, the operator must move the mark detector 57 in the width direction of the web 1 by manual or remote control operation to find a position where the mark detector 57 can detect the mark 2. It was hanging. Further, since the web 1 continues to flow until the mark detector 57 is arranged at an appropriate position, the amount of waste paper increases as the above work takes longer.
[0007]
Further, as shown in FIG. 7B, when the mark 2 is not printed on the web 1, the edge portion 5 of the pattern 3 is set as the mark 2, and these are detected by the mark detector 57, Although it is generally known to use it for cutting position control, in this case as well, an operator manually moves the mark detector 57 to a position where the mark 2 exists within the detection range of the mark detector 57 by remote control operation. It is necessary to move in the web 1 width direction, and there is the same problem as described above.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic configuration diagram schematically showing a cutting control device for a printing press as one embodiment of the present invention.
As shown in FIG. 1, the web 1 is conveyed from the paper supply unit 51 to the printing unit 53 via the guide roller group 52, and the design is printed on the web 1 by the printing unit 53. Thereafter, the web 1 is dried by the dryer unit 54, conveyed to the folding machine 56 through the web path unit 55, and cut in the web 1 width direction by the saw cylinder 60.
[0014]
  At this time, in the cutting control device of the printing press according to the present embodiment, the control unit 13 includes a reference pulse from the encoder 61 that rotates in synchronization with the saw cylinder 60 and a mark (cut register) on the printed web 1. The timing when the web 1 is cut by the saw cylinder 60 and the time when the mark is detected by the mark detector 6 based on the detection signal from the mark detector 6 such as a CCD camera that detects the mark or the edge of the pattern) And the compensator low through the motor 58 so that they match or have a predetermined differenceLa59 is driven and the tension applied to the web 1 is changed to adjust the above-described timing shift, and the web 1 can be cut at a predetermined position.
[0015]
In addition, the cutting control device includes an image data storage unit 10, an image data conversion unit 11, a mark position calculation unit 12, a drive unit 14 for the mark detector 6, a display 15, and a current position for estimating the current position of the mark detector 6. An estimation means 16 is provided.
The image data storage means 10 is image data that is the basis of a picture printed by the printing unit 53 [image data obtained by processing digital data for plate making used in the CTP system or image data that is the origin of a picture to be printed (for example, , CIP3 / 4 standard digital data)] is acquired online from the plate making process and stored. The image data is stored in the image data storage means 10 with a resolution of about 2400 dpi if the image data is the basis of the picture to be printed, and with a resolution of about 50 dpi if the digital data is CIP3 / 4 standard. Accumulated.
[0016]
The image data conversion means 11 converts the image data from 2400 dpi or 50 dpi to a resolution of the mark detector 6 of 10.16 dpi in order to match the resolution of the image data to the resolution of the mark detector 6.
[0017]
As shown in FIG. 2, the minimum unit of the mark 2 that can be detected by the mark detector 6 used in the present embodiment is 10 mm in the web 1 width direction and 1 mm in the web 1 flow direction. Further, in order to be detected as the mark 2 by the mark detector 6, a space of 10 mm or more is required above the mark 2 shown in FIG. 2 (that is, upstream of the mark 2). Since the length of the mark 2 in the width direction of the web 1 is 10 mm, in the mark detector 6 according to this embodiment, the mark position indication needs to have an accuracy of at least 5 mm. In order to obtain an indication accuracy of 5 mm, it is necessary that the equivalent width of at least 1 pixel is 2.5 mm. That is, when 1 pixel is 2.5 mm, it is 10.16 dpi, so the image data conversion means 11 converts (reduces) it to 10.16 dpi.
[0018]
Note that the mark position indication accuracy depends on the field of view of the mark detector 6. If the field of view of the mark detector 6 is wide, the mark position indication accuracy may be coarse. That is, in the mark detector 6 according to the present embodiment, it is possible to find the mark 2 if the accuracy is 5 mm (that is, the mark 2 enters the field of view of the mark detector 6).
[0019]
As shown in FIG. 1, the mark position calculation unit 12 calculates the mark position based on the image data reduced by the image data conversion unit 11. Specifically, as shown in FIG. 3B, the mark position is calculated by matching the image 31 reduced by the image data conversion unit 11 with the template 30 as shown in FIG. It is supposed to be. In this matching, a residual sequential test method as shown below is used.
[0020]
In the template 30, since 1 pixel corresponds to 2.5 mm at 10.16 dpi, the mark 2 shown in FIG. 2 and the blank that must exist before the mark 2 are ideally shown by pixels. Further, the black portion of the template 30 corresponds to the mark 2 and the white portion corresponds to the blank, the black portion is the maximum pixel value that can be taken, and the white portion is 0.
[0021]
First, the template 30 is superimposed on the upper left of the image 31, and the difference between each pixel value of the template 30 and each pixel value at a position corresponding to the template 30 of the image 31 is obtained and accumulated. If this cumulative value is equal to or less than a certain threshold value, this position (in this case, the position corresponding to the upper left of the image 31) is recorded as a position where there is an image close to the template 30 (that is, the mark 2 is likely). Next, the template 30 is shifted by one pixel and the same operation is performed, and the image 31 is sequentially scanned.
[0022]
Since it is sufficient for the mark detector 6 to be able to detect the mark 2, processing is usually performed with a gray scale image (so-called black and white image). However, since a single edge of yellow (Y) is difficult to detect (yellow is thin when viewed in black and white), when performing the above matching, the mark 2 portion of the template 30 is cyan ( C), a magenta (M), and a black (K) superimposed image are used, and a blank image portion of the template 30 is a superimposed image of all colors.
[0023]
By such pattern matching, the mark position calculation unit 12 calculates a plurality of mark candidates that can be used as the mark 2.
Then, the mark position calculation means 12 calculates the mark 2 closest to the current position in the web 1 width direction of the mark detector 6 estimated by the current position estimation means 16 described later from the plurality of mark 2 candidates, The mark 2 is set as the optimum mark 2.
[0024]
As shown in FIG. 4, the driving means 14 includes, for example, base members 23 and 24 installed on both ends of the web 1 and both ends fixed to the base members 23 and 24 and the width of the web 1 of the mark detector 6. A support rail 22 that supports movement in the direction, and is provided in parallel with the support rail 22, one end of which is rotatably supported by the base member 23, and an intermediate portion is screwed into the screwing hole 6 a of the mark detector 6. And a drive motor 20 that is connected to the other end of the rotary roll 21 and rotates the rotary roll 21 in response to a control signal from the control means 13.
[0025]
Accordingly, when the drive motor 20 is driven to rotate, the rotary roll 21 rotates, and the mark detector 6 can move between one end side and the other end side of the web 1 as the rotary roll 21 rotates. It has become.
The current position estimation means 16 determines whether the mark detector 6 is based on the rotational position of the drive motor 20 detected by a potentiometer (not shown), the groove width of the spiral groove of the rotary roll 21 and the like (for example, in FIG. The amount of movement of the mark detector 6 is calculated, and the current position of the mark detector 6 in the width direction of the web 1 is estimated.
[0026]
By the way, the control means 13 described above drives the drive motor 20 to move the mark detector 6 in the width direction of the web 1 to a position where the mark 2 calculated by the mark position calculation means 12 can be detected. Yes. When the mark detector 6 detects the mark 2, the control means 13 controls the driving means so as to stop the mark detector 6 at that position.
[0027]
The control means 13 displays the distance between the mark position and the current position of the mark detector 6 on the display 15. For example, in FIG. 4, when the mark 2 passes through the position 30 cm above the mark detector 6 in FIG. 4, “+30 cm” or the like is displayed on the display 15, and for example, from the mark detector 6 In the case where the mark 2 passes through the position 5 cm below in FIG. 4, “−5 cm” or the like is displayed on the display 15. Therefore, the operator can see the display 15 and confirm how much the mark detector 6 should be moved to which side.
[0028]
Since the cutting control device for a printing press according to an embodiment of the present invention is configured as described above, first, the plate making stored in the image data storage unit 10 is performed by the image data conversion unit 11 before starting printing. The resolution of the image data obtained by processing the image data for printing or the image data for plate making is converted (reduced) to the resolution of the mark detector 6.
Next, a plurality of mark 2 candidates that can be used as the mark 2 are calculated by pattern matching of the mark position calculating unit 12, and the mark detection estimated by the current position estimating unit 16 from the plurality of mark 2 candidates. The position of the mark 2 closest to the current position of the device 6 is calculated, and the mark 2 is set.
[0029]
Then, the control means 13 drives the drive motor 20 based on the position information of the mark 2 calculated by the mark position calculation means 12, and moves the mark detector 6 to the position where the mark detector 6 can detect the mark 2. Move in the width direction. At this time, the distance between the mark 2 position and the current position of the mark detector 6 is displayed on the display 15.
Then, after the movement of the mark detector 6 is completed, normal printing is started and the web 1 is cut.
[0030]
Thus, in this cutting control device, since the mark 2 on the web 1 can be detected from the start of printing, the cutting position of the web 1 can be kept constant, and the waste paper can be greatly reduced.
Further, since the mark detector 6 is moved to the position of the mark 2 closest to the current position of the mark detector 6 from among the plurality of mark 2 candidates, the movement time of the mark detector 6 can be reduced, and preparations for starting printing Time can be shortened.
[0031]
Furthermore, even if the drive motor 20 fails, the distance between the current position of the mark detector 6 and the position of the mark 2 is displayed, so that the operator looks at the display 15 and sees the mark detector. Since it is possible to know to which side in the width direction of the web 6 it should be moved, if the mark detector 6 can be manually moved in the width direction of the web 1, the operator manually marks it directly. It is also possible to move the detector 6 to a desired position.
[0032]
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in the present embodiment, the control unit 13 controls the driving unit 14 to move the mark detector 6 based on the position of the mark 2 calculated by the mark position calculation unit 12. Without providing a system for automatically moving the mark detector 6, the display 15 simply displays the distance between the current position of the mark detector 6 estimated by the current position estimating means 16 and the position of the mark 2. It is only necessary to provide a cutting assist device configured as described above. As a result, it is possible to prompt the operator to move the mark detector 6 and to notify how much the mark detector 6 should be moved. Therefore, the operator can directly move the mark detector 6 before starting printing by looking at the display on the display 15.
[0033]
Further, similarly to the above, without providing a system for automatically moving the mark detector 6, the positional relationship between the current position of the mark detector 6 estimated by the current position estimating means 16 and the position of the mark 2 is simply displayed. 15 may be provided only with a cutting assist device configured to display an image schematically. Even with this configuration, it is possible to prompt the operator to move the mark detector 6, and the operator can directly move the mark detector 6 before starting printing by looking at the display on the display 15. .
[0034]
Even when the cutting assisting device as described above is provided, the mark detector 6 can be moved in advance to an appropriate position before the start of printing, as in the case where the cutting control device of the present embodiment is provided. That is, since the mark 2 on the web 1 can be detected from the start of printing and the cutting position of the web 1 can be kept constant, the amount of waste paper can be greatly reduced.
[0035]
In addition to the schematic image showing the positional relationship between the current position of the mark detector 6 and the position of the mark 2, the distance between the current position of the mark detector 6 and the position of the mark 2 is displayed on the display 15. It may be displayed.
A known linear motion device may be used as means for moving the mark detector 6 in the web 1 width direction.
