(D) Printing step and (inline printing device part 31)
(E) a step of sorting; (sorting device part 41)
A high-speed web printing machine (10) provided with a continuous line in-line printing apparatus according to the present invention, comprising: (See Fig. 1)
[0017]
Next, the processing procedure of the present invention will be described in order from the beginning. The print processing section (1) is provided with an identification mark printing portion (21) for printing the identification mark of the present invention near the end of the printed matter simultaneously with the text of the printed matter.
[0018]
In the post-processing unit (2), after the roll-shaped printed material is folded by a folding machine and cut to a predetermined length, the printed materials are sequentially shifted at equal intervals and overlapped, and run on a belt conveyor while the alignment device part ( The position and inclination of the identification mark on the printing unit which is aligned on the belt conveyor by the alignment means of 33) and is monitored and measured by the next sensor unit (32) is measured by the monitoring and measurement means of the next sensor device part (32). The measured value is compared with a pre-registered allowable range to select a printed material that is normal within the range and aligned, and outputs a print instruction signal for the printed material to the in-line printing device (31).
[0019]
Next, the individual information (52) is printed at the identification mark position of the printed matter by the printing means of the in-line printing device (31).
[0020]
Next, in the paper discharge section (4), the unprinted printed matter is sorted out from the belt conveyor (11) by a sorting device portion (41) provided with means for sorting only printed matter on which the individual information has not been printed. Is collected on a collection belt conveyor (12).
[0021]
Therefore, since the printed material is processed based on the processing procedure of the present invention, the quality of all printed materials discharged from the paper discharge unit (4) is assured as good. In addition, the collected printed matter can be sorted again and appropriately treated.
[0022]
The above-described processing procedure of the present invention is sequentially automated with the processing steps, processing means, and a program of an automation system, and is provided in a system control unit of the printing apparatus, and an in-line printing apparatus for performing printing processing provided with the program. A high-speed web printing machine (10) provided with:
[0023]
As shown in the plan view of FIG. 2A, this is an example in which an identification mark (51) is printed on a printing area (50) secured at the leading end of a printed matter (100). The identification mark needs to be able to measure the position and inclination. That is, it is preferable that the outer shape of the text and the printed matter (100) and the identification mark have the same matrix arrangement (the same arrangement as the page layout). The identification mark of the present invention requires the arrangement of a pattern whose position and inclination can be measured depending on the sensor device portion (32). For example, as shown in FIG. 2A, two square black patterns are arranged diagonally, and the distance and the inclination from the origin position on the belt conveyor (11) are measured.
[0024]
FIG. 2B shows an example in which individual information (52) such as a management number is printed by an ink jet printer (32). Individual information (52) is printed in an area at a predetermined distance from the identification mark. FIG. 2B shows a normal printed matter.
[0025]
Further, as shown in the side sectional view of FIG. 3A, the post-processed portion (3) of the present invention is printed on the printed matter (33) aligned by the aligning device portion (33) while running on the belt conveyor (11). In 100), the identification mark is measured by a sensor (32a) installed so as to face the upper surface of the belt conveyor (11), and the position and the inclination are monitored.
[0026]
The sensor (32a) is a device that captures information regarding the state and characteristic values of the measurement target, and is, for example, an image capturing device that includes a laser, a CCD, or the like. Further, the information processing device includes a process of converting information of a captured state or characteristic value into a signal or the like, or an image process, a simple arithmetic process, or the like, or a process of storing information and transmitting information output. 32a) is included in the sensor device portion (32). Further, the sensor device portion (32) is connected to the in-line printing device portion (31) via a network for inputting and outputting information.
[0027]
Next, the printed matter (100) is selected based on the measured values of the position and the inclination, and a print instruction signal for the selected printed matter is output to the in-line printing device part (31) in the next step. Subsequently, the inline printing device part (31) prints the individual information (52) on the printed material using an ink jet printer (31a).
[0028]
As shown in the plan view of FIG. 3B, the sensor device portion (32) measures the position and inclination of the printed matter placed on the belt conveyor. The sensor device part (32) measures the distance and position between the reference points (13) provided on the left and right sides of the equipment body, for example, the frame part, and each identification mark (51). First, the distance is calculated, for example, by measuring the distance to the center line of the reference point (13) provided on the left and right and the center line of the left and right identification mark (51). Next, the inclination is calculated, for example, by measuring the distance from a straight line connecting the reference point (13) (see the broken line in FIG. 3B) to the left and right identification marks (51). The distance and the inclination in the width direction of the printed matter (100) are calculated from the measured values. In addition, the reference value registered in advance and the reference value in which the position of the allowable range is registered is compared with the actually measured position to determine a pass or a reject, and a print instruction signal for the passed print is sent to the in-line printing device part ( 31).
[0029]
Next, the inline printing device part (31) prints the individual information (52) on the corresponding printing part using the ink jet printer (31a) in accordance with the print instruction signal.
[0030]
【The invention's effect】
When the apparatus of the present invention overlaps more than the limit or inclines at an angle, the inline printing apparatus does not perform printing, and unprinted printed matter is sorted and collected on the collection belt conveyor from the belt conveyor, so that unprinted and character Prints such as missing or bent prints are removed and collected. In addition, by using a high-speed web printing machine equipped with the inline printing apparatus of the present invention, printed matter is correctly printed at a predetermined position, and there is an effect that the problem of defective printed matter can be solved. Further, the step of inspecting and sorting printed matter is not required, and the productivity is improved and improved.
