Abstract

PURPOSE:To alleviate labor in searching for and removing a paper with a joint, by operating a page counter by an output from a joint-detecting means, detecting the number of pages extending from a joint-detecting position to a post-processing device, and informing the operator of the result. CONSTITUTION:A processor 51 refers to the contents of a flag area 52a in memory 52 to check whether or not counting is required. When it is decided that the counting is required, a joint is detected by a joint sensor 26, and after a flag is set ON, the processor 51 adds '1' to the contents of a page count area 52b in the memory 52. The contents of the area 52b is compared with a reference value (n), and when the contents of the area 52b is not less than the reference value (n), the processor 51 outputs a buzzer turning-ON command to an output port 54 through a bus 57. Then, a post-processing controlling part 35 operates a buzzer 43 to inform the operator of the arrival of paper with a joint at a conveyor stacker CSU. The operator checks business forms received on the stacker CSU, and remove the paper with the joint.

By providing this, the operator is notified that the joint portion of continuous paper has reached the post-processing device.

[Industrial application field]

The present invention provides a print processing system that performs processing such as printing on continuous paper such as folded paper, then cuts it as post-processing and stores it as a form. The present invention relates to a paper seam processing method that can detect a form including a seam during processing.

Print processing systems that perform processing such as printing and recording while feeding continuous paper are widely used. In such print processing systems, since the processed continuous paper itself is difficult to handle, the continuous paper is cut and stored in a post-processing device.

For example, in the print processing system shown in FIG.
The device LBP prints page by page.

The paper is sent to the paper post-processing device APP, and is cut by the paper post-processing device APP and stored as a page-by-page form.

[Conventional technology]

In such a print processing system, if the processing speed is improved, it will not take much time to process the standard length continuous paper PP. Therefore, each time a standard length continuous sheet is processed, the apparatus must be stopped until the next continuous sheet is manually set in the hopper STC, reducing the operating rate of the apparatus.

For this reason, as shown in the 7th installation, the ends of standard length continuous paper PP are joined using seam tape PT.

A long continuous sheet is formed and set in a hopper STC.

On the other hand, if such long continuous paper is used.

Seam pages with seam tape do not perform printing or other processes well, so they are not printed and are left as blank pages. To control this printing, seam detection holes DH are provided on the seam pages. In Figure 2, three blank pages are created before and after the seam.

The printed continuous paper on which such blank pages have been created is cut and stored in the post-processing device APP.

[Problem that the invention seeks to solve]

Therefore, according to the prior art, when the post-processing device [APP] stores the blank pages as shown in FIG. Since a blank page is extracted from a unit of printed matter, a problem arises in that it takes time and effort to find out from among the printed matter whether or not there is a blank page, and where the blank page is located.

SUMMARY OF THE INVENTION An object of the present invention is to provide a paper seam processing method for a print processing system that can reduce the effort by detecting the arrival of a seam sheet related to a post-processing device and notifying the operator.

[Means for solving problems]

FIG. 1 is a diagram explaining the principle of the present invention.

In the present invention, a page counter (
The page counter is configured to operate based on the output of the seam detection means for detecting seams.

Then, the operator is notified that the number n of pages corresponding to the number of pages from the G-eye detection position to the post-processing device (for example, the storage position) has been detected.

[For production]

In the present invention, the seamed paper is tracked by a page counter, and when the seamed paper reaches the post-processing device, the operator is notified so that the seamed paper can be extracted and found on the spot. It is.

Therefore, the operator's effort due to seamed paper can be significantly reduced.

■ The processor 51 uses the flag area 52a of the memory 52.
Refer to the contents and check whether counting is required.

(2) If counting is not necessary, the processor 51 checks whether the input port 53 and the seam sensor 26 detect a seam and generate a seam detection signal.

If no seam detection signal is generated, the process ends.

If a seam detection signal is generated, a count is required.

Then, the contents of the page count area 52b and the reference value n
Compare with. This reference value n is a value obtained by converting the distance from the seam sensor 26 to the entrance of the conveyor stacker C8U, that is, the sensor 35, into the number of pages.

This varies depending on the paper length.

If the content of the page count area 52b is smaller than the reference value n, the paper at the seam has not reached the entrance of the conveyor stacker C8U, so the process ends.

■ On the other hand, if the content of the page count area 52b is equal to or greater than the reference value n, the paper at the seam is stacked on the conveyor stacker C8U.
Since the entrance has been reached, the processor 51 issues a buzzer-on command to the output port 54 via the path 57, and the drive control unit 55 issues a buzzer-on command to the post-processing control unit 35.

When the buzzer switch is turned on, the buzzer of the buzzer part 43 is turned off (stopped) and the process ends.

In this way, when the seam sensor 26 detects a seam, it counts page signals from the cutting device PCM.

When it is detected by the count value that the seamed paper has reached the position of the conveyor stacker C8U, the buzzer 43 sounds to notify the operator.

The operator then looks at the sheets stored on the conveyor stacker C8U and removes the seam sheet (blank page).
