FIG. 2 is a flow chart showing the flow of processing of defective position indication recording according to the present invention. The present invention will be described below with reference to FIG. 2 and FIG. 1 described above. In FIG.
First, the web route data is read. The web path is a transfer path in a production machine such as a printing machine for a web that is set in a paper feed unit by a winding body, is unwound and supplied, and is rewound in the winding unit after being processed. This web route depends on the product. For example, one item may be overprinted with 6 colors and another item may be overprinted with 4 colors and then overcoated. Normally, when the production item and the production machine are decided, the web route is also decided.

Since it is, for example, the production control system 3 that the production plan is set up, the production control system 3 has data relating to production items and production machines, and therefore has web route data or basic data. Further, the web route data or the basic data also exists in the preset system (see FIGS. 3 and 5 described later) for setting the operation mode and conditions of the production machine according to the production plan. Also, the operator of the production machine can manually input the web route data into the defect instruction recording device.

If the production machine is a printing machine, the web route data includes whether the web of the winding body is fed out upwards or downwards in the paper feeding section, a system via a guide roller, a route for introducing and discharging the web to the printing unit, and drying. The introduction and discharge route of the web to the unit, the connection route of the web between the units, the upper and lower winding of the web in the winding section, and the like. However, the typical pattern of the web path varies depending on the printing machine.
Since it is limited to dozens of types, the web route data can be replaced with the web route number by giving the web route number to the typical pattern of the web route of each printing machine. As mentioned above, the web route data is first read. In FIG. 1, the process control system 3 to L
The web route data 10 is read into the defect indication recording device 1 through the AN2 (S1).

Next, detection distance data calculation processing is performed based on the read web route data to generate detection distance data. The detection distance data is the distance from the detection point for detecting a web defect to the running position measurement point. In the detection distance data calculation processing routine 13, parameters corresponding to the blueprint of the web route of the production machine provided with the defect indication recording device 1 are set, and the detection distance data is generated from the parameters and the web route data. . The number of detection points is not limited to one, and a plurality of detection points can be provided on the web path. Therefore, the detection distance data is generated in the same number as the number of detection points.
When the web route has a typical pattern and the web route data is given by the web route number, the detection distance data calculation processing routine 13 holds a correspondence table of the web route number and the detection distance data. The detection distance data can be generated by referring to the table (S2).

Next, the process waits until a failure signal indicating that a failure of the web has been detected at the above-mentioned detection point is input. The defect signal is not limited to the output signal of the inspection device, but may be generated manually by an operator or the like when a defect is detected by manual inspection (S3). When the defect signal is input to the defect instruction recording device 1, the measured distance data that is the web transfer distance at that time is input. A transfer distance measuring device 4 for measuring the transfer distance of the web is installed at the traveling position measuring point, and the measured distance data is output from the transfer distance measuring device 4. This measured distance data is normally given from the start of production of non-defective products (original paper) that is input by the operator, but is not particularly limited (S4).

Next, defective position data calculation processing routine 1
4, the defective position data is generated from the measured distance data and the detected distance data. The calculation is performed by the mathematical formula shown by the following expression 1 (S5).

[Equation 1] (Defective position data) = (Measurement distance data) +
(Detection distance data)

Next, the attached distance data calculation processing routine 1
The calculation is performed by 5 to generate the attached distance data.
The attachment distance data is the distance from the point where the tape is attached to the web to the running position measurement point. The tape is attached to the web so that the position on the web such as a defective position can be used as a mark so that it can be seen from the outside even after the web becomes a winding body. The attached distance data is generated by the same calculation process (see S2) as in the case of the above-described detected distance data (S6).

Next, attached position data arithmetic processing routine 1
The calculation is performed by 6, and attached position data is generated from the attached distance data, the detected distance data, and the measured distance data described above. The calculation is performed by the mathematical formula shown by the following Expression 2 (S7).

[Equation 2] (attached position data) = (measured distance data) +
(Detected distance data)-(Attached distance data) However, (Detected distance data)> (Attached distance data).

As for the defective position data and the attached position data generated in the above processing steps, the same number of data as the number of defective signals is generated. The defective position data and the attached position data are aggregated as quality information of the web winding body each time or for each winding body and transferred to the process management system 3. Further, the attachment position data or the insert signal is output to the tape inserter so that the tape is inserted and attached to the web when the attachment position data and the measured distance data match (S8). It is determined whether or not the defective position indication recording process is to be continued. When the production of the produced item is finished, the process is finished, and if it is continued, the process returns to S3 to repeat the above process ( S9).

Next, the present invention will be described with reference to specific examples applied to a printing machine, a coating apparatus and the like. FIG. 3 is a diagram showing an example when the defect indication device of the present invention is applied to a printing machine, a coating device, and the like.

If a defect is detected as a result of these inspections, the operator turns on the button switch of the input device 101, and the inspection device automatically generates a defect signal (S103). The defective signal is transferred to the process control terminal 103 (S104). Process control terminal 1
When the defective signal is input, 02 adds the length data from the quality defect inspection point where the defective signal is issued to the traveling position measuring point 107 to the web transfer distance data at the traveling position measuring point 107, and adds the data. The position data thus obtained is recorded as quality defect position information (105).

It is determined whether the defective position indication recording process is to be continued or to be finished. If it is finished due to the production of the production item being finished, the process is finished, and if it is to be continued, it is S103.

Next, the preset device 208 sets the printing machine based on the data. As a result, the web path is determined, the lengths from the first to third quality defect inspection points to the running position measurement point 212 and the tape inserter 207 are calculated, and the distance data thereof is transferred from the preset device 108 to the position correction device 202.
