(Local Area Network), 3 is capable of mutually transferring data to and from the defect removing device main body through a LAN, and the defect removing device main body for removing defects from the web based on the data obtained by the defect removing device main body, 4 is a button An operation panel 5 including an input device such as a switch, a keyboard and a mouse and an output means such as a display and a printer is a storage medium such as a floppy disk.

In FIG. 1, the failure indication device main body 1 is further composed of details, 6 is a storage means, 7 is an input / output control means, and 8 is a calculation means, and these are personal computers, engineering workstations, etc. It is a main body of a computer or a control device such as a sequence control device having an arithmetic function. And computing means 8
In the above, 9 is a marking processing routine, 10 is a transfer distance measurement processing routine, and 11 is a defective memory processing routine.

Further, 12 is an inspection device, 13 is a marking device, and 14 is a distance measuring device, which are connected to the failure indicator main body 1 to transmit and receive signals or data. On the other hand, 15 is a paper feeding unit, 16 is a printing, coating and other processing unit, 17 is a winding unit, and these are units of a manufacturing and processing apparatus. Further, 18 is a web, and 19 is a winding body on which the web is wound.

The operation of the failure indication device body 1 of the present invention having the above-mentioned configuration will be described. The web 18 supplied from the paper feeding unit is transferred to the processing unit 16 where it is processed. Further, the web 18 is transported and finally reaches the winding unit 17, and is wound to become a winding body 19. When the web 18 is transferred between the processing unit 16 and the winding unit 17, the inspection device 12 and the marking device 1
3, go through the distance measuring device 14, inspection, marking,
Distance measurement is performed. At least the start position and the end position of the winding body 19 of the web 18 are marked by the marking device 13. The distance measurement values at the time when the start position and the end position are marked are stored, and the start position mark and the end position mark and the web 18 between them are stored.
Is associated with the distance measurement value (details will be described later).

At the time when the processing conditions are adjusted and the normal paper (good product) is discharged from the processing unit 16,
The operator inputs from the operation panel 4 that the production of original paper has started in the failure indication device body 1. The position of the web 18 at which the production of the standard paper starts, that is, the start position of the standard paper can be set as the start position of the winding body, and the position of the web 18 is marked. The starting position of the winding body is the web 1
8 is set near the core of the winding body 19, and the end position of the winding body is set near the outer circumference of the winding body 19 of the web 18. As a result, the position of the required portion of the web 18 such as plain paper can be associated with the distance measurement value.

In this way, the marking processing routine 9
The marking device 1 is operated by the operator's input signal of the original paper.
A marking operation command signal is output to 3. Further, the transfer distance measurement processing routine 10 reads the distance measurement value from the distance measurement device 14 in response to the operator's original sheet input signal,
It is stored in the storage means 6 in association with the original paper input. When the distance measuring device 14 outputs or displays the transfer distance of the original paper, the transfer distance measurement processing routine 10 resets the distance measuring device 14 by the operator input signal of the original paper and sets the distance measurement value to “0”. Then, the distance is measured again.

After the start position mark of the winding body is written on the web 18 as described above, the transfer distance measuring processing routine 1
0 continues to measure the transfer distance of the web 18 and calculates the transfer distance of the web 18 starting from the start position. The calculated transfer distance is monitored by the marking processing routine 9. The defect indicating device body 1 does not mark only the start position and the end position of the winding body, but marks the web 18 at each predetermined transfer distance of the web 18 starting from the start position by switching the mode. You can The setting of the transfer distance of a predetermined amount and the setting of the mode are performed by an operator inputting from the operation panel 4 or setting a predetermined value as a default.

In the marking processing routine 9 in the mode in which the mark is written on the web 18 for each predetermined amount of transfer distance, the predetermined amount of transfer distance is calculated based on the transfer distance calculated by the transfer distance measurement processing routine 10. A signal indicating a mark (a predetermined amount transfer mark) on the web 18 for each transfer distance is output to the marking device 13. Further, the transfer distance measurement processing routine 10 reads the distance measurement value from the distance measuring device 14 and stores it in the storage means 6 in association with the number of the signal describing the predetermined amount transfer mark.

In this case, it is natural that the mark at the end position is the same as the last mark for each predetermined amount of transfer distance, but it is not always necessary to do so. After the operator inputs an end signal from the operation panel 4, the marking processing routine 9 outputs a marking operation command signal to the marking device 13. The operator's operation panel 4
After the end input from the transfer distance measurement processing routine 10
Reads the distance measurement value from the distance measurement device 14 and stores it in the storage means 6 in association with the end input.

When the inspection device 12 outputs a defect detection output between the start position and the end position of the web 18, the transfer distance measurement processing routine 10 receives the defect detection signal and measures the distance. The distance measurement value is read from the device 14, and the defect storage processing routine 11 stores the distance measurement value at the time of input as defective position data in the storage means 6. In addition, the defect content data indicating the content of the defect is inspection device 1
In the case of being output from 2, the defect content data is stored in the storage means 6 at the same time by the defect storage processing routine 11 as well as the distance measurement value. The contents of the defect include defect position data in the width direction perpendicular to the transport direction of the web 18, defect attribute data relating to the defect size, color, density and the like. Note that there is a defect such as a doctor streak that occurs continuously over a long distance, but in that case, in the case of a printing apparatus, a section corresponding to one circumference of the plate cylinder is provided, and data is aggregated for each section and the storage unit 6 Remember.

In this way, the data stored in the storage means 6 is generated as a data file for each winding body, stored in the storage medium 5 such as a floppy disk, and managed together with the winding body 19 to be defective. It is delivered to the next process such as the extraction process. Alternatively, instead of storing in the storage medium 5, L
The data file is transferred through the AN2 to a device in the next process such as a defective sampling device. The distance data indicating the mark position and the defective position of the data stored in the storage unit 6 when the data file is generated is the distance data of the start position mark, the distance data of the end position, or the transfer distance of a predetermined amount. The data is rewritten using the distance data of the attached mark as the reference position (starting point or ending point).
