The removing device 16 is arranged, for example, on the most downstream side in the third step. The third step is the final step of processing the continuous sheet 30. After removing the poor quality portion F of the continuous sheet 30, for example, the removing device 16 reconnects the removed portion of the continuous sheet 30 and the corresponding edges.

The operation of the quality monitoring system 10 will be described with reference to FIGS. 2 to 4.
The sheet manufacturing system 1 processes the continuous sheet 30 in the order of, for example, the first step, the second step, and the third step. The first step is a step of printing the surface 30D of the continuous sheet 30 using, for example, the first processing device 21 (see FIG. 1). The second step is a step of applying a coating process to the surface 30D of the continuous sheet 30 by using, for example, the second processing device 22 (see FIG. 1). The third step is a step of removing the poor quality portion F of the continuous sheet 30 by using, for example, the removing device 16.

As shown in FIG. 2, in the first step, the sheet manufacturing system 1 unwinds the continuous sheet 30 from the roll-shaped raw fabric P wound on the first reel R1 and winds the continuous sheet 30 from the first reel R1 to the second reel R2 ( The continuous sheet 30 is conveyed toward (see FIG. 3). The recording device 11 records the position information IP on the continuous sheet 30 being conveyed unwound from the first reel R1. In one example, the recording device 11 records position information IPs at predetermined intervals on the surface 30D of the continuous sheet 30 at one end 30E of the continuous sheet 30 in the lateral direction. Therefore, a plurality of position information IPs are recorded on the continuous sheet 30 along the longitudinal direction of the continuous sheet 30. For example, after the position information IP is recorded, the continuous sheet 30 is printed by the first processing apparatus 21.

As shown in FIG. 3, the first reading device 12A reads the position information IP recorded on the continuous sheet 30 after the printing process of the continuous sheet 30, and each time the position information IP is acquired, the position information IP is first information. It is output to the generation unit 14A (see FIG. 1). The first defect detection device 13A detects the quality defect portion F existing in the continuous sheet 30 after the printing process of the continuous sheet 30, and each time the quality defect portion F is detected, the quality defect information IF is sent to the first information generation unit 14A. Output. Each time the first defect detection device 13A detects the quality defect portion F, the first information generation unit 14A generates a defect position information PF in which the position information IP at that time and the quality defect information IF are associated with each other, and the generated defect is generated. The position information PF is output to the third information generation unit 14C (see FIG. 1). The continuous sheet 30 that has passed through the first defect detection device 13A is taken up by the second reel R2.

In the second step, the sheet manufacturing system 1 unwinds the continuous sheet 30 from the second reel R2 and conveys the continuous sheet 30 from the second reel R2 to the third reel. In the second step, the arrangement of the position information IPs recorded on the continuous sheet 30 is reversed in the direction in which the continuous sheet 30 is conveyed (not shown). The continuous sheet 30 is coated, for example, by the second processing apparatus 22. The second reading device 12B performs substantially the same operation as the first reading device 12A after the coating process of the continuous sheet 30, and outputs the acquired position information IP to the second information generation unit 14B (see FIG. 1). The second defect detection device 13B executes substantially the same operation as the first defect detection device 13A after the coating process of the continuous sheet 30, and outputs the acquired quality defect information IF to the second information generation unit 14B. Like the first information generation unit 14A, the second information generation unit 14B generates a defective position information PF in which the position information IP and the quality defect information IF are associated with each other, and the generated defective position information PF is used as the third information generation unit 14C. Output to. The continuous sheet 30 that has passed through the second defect detection device 13B is wound on the third reel.

As shown in FIG. 4, the third information generation unit 14C generated and generated the defect position table TF based on the plurality of defect position information PFs acquired from the first information generation unit 14A and the second information generation unit 14B. The defective position table TF is stored in the server 15. The symbol “◯” in FIG. 4 indicates the position information IP of the poor quality portion F existing in the continuous sheet 30. In one example, the defect position table TF shows that the quality defect portion F detected in the first step exists in the portion of the continuous sheet 30 where the position information IPs correspond to "7" and "18", and the second The poor quality portion F detected in the process indicates that the position information IP of the continuous sheet 30 exists in the portion corresponding to “9” and “11”.

In the third step, the sheet manufacturing system 1 unwinds the continuous sheet 30 from the third reel and removes the defective quality portion F by the removing device 16. The removing device 16 removes the poor quality portion F of the continuous sheet 30 based on the position information IP and the defective position table TF. In one example, the portion of the continuous sheet 30 whose position information IP corresponds to "7", "9", "11", and "18" is removed. Then, the removing device 16 reconnects the removed portion of the continuous sheet 30 and the corresponding edges. In one example, the removing device 16 reconnects the edge of the portion of the continuous sheet 30 corresponding to the position information IP "6" and the edge of the portion corresponding to the position information IP "8". Through the above steps, a desired sheet is produced from the roll-shaped raw fabric P.

According to the quality monitoring system 10, the position information IP is recorded on the continuous sheet 30, and the defective position information PF in which the position information IP is associated with the quality defect information IF is generated. Therefore, the removal device 16 records on the continuous sheet 30. By acquiring the position information IP, the quality defect portion F of the continuous sheet 30 corresponding to the defect position information PF can be accurately detected. Further, by removing the detected defective quality portion F of the continuous sheet 30, the defective quality portion F existing in the continuous sheet 30 is accurately removed. Therefore, other than the defective quality portion F of the continuous sheet 30. The part is difficult to remove. Therefore, the yield of the continuous sheet 30 is unlikely to decrease. Further, unlike the configuration in which the identification label is attached to the continuous sheet 30, the position information IP does not peel off from the continuous sheet 30.

(Second Embodiment)
The quality monitoring system 10 of the second embodiment is different from the quality monitoring system 10 of the first embodiment in the points described below, and has substantially the same configuration as the quality monitoring system 10 of the first embodiment in other respects. Be prepared.

The configuration of the sheet manufacturing system 1 will be described with reference to FIG.
The continuous sheet 30 includes a first continuous sheet 31 and a second continuous sheet 32, and is a sheet in which the first continuous sheet 31 and the second continuous sheet 32 are bonded together. The first continuous sheet 31 is a sheet in which various processes are performed through the first step and the second step, and the first position information IP1 which is the position information IP is recorded. An example of the first continuous sheet 31 is a PET sheet. The second continuous sheet 32 is a sheet in which various processes are performed through the first step and the second step, and the second position information IP2, which is the position information IP, is recorded. An example of the second continuous sheet 32 is a PE (Polyethylene) sheet.

The processing apparatus 20 further includes a third processing apparatus 23. The third processing apparatus 23 is, for example, an apparatus for bonding the first continuous sheet 31 and the second continuous sheet 32 in the fourth step. The fourth step is, for example, a step carried out between the second step and the third step in a plurality of steps for processing the continuous sheet 30. In one example, the back surface of the first continuous sheet 31 and the front surface 30D of the second continuous sheet 32 are bonded to each other by the third processing device 23 to generate a continuous sheet 30 having a two-layer structure.

The reading device 12 further includes a first correction reading device 41 and a second correction reading device 42. The first correction reading device 41 reads the first position information IP1 recorded on the first continuous sheet 31. The first correction reading device 41 is on the upstream side of the merging point C so that the first position information IP1 immediately before the merging of the first continuous sheet 31 and the second continuous sheet 32 can be read, for example, in the fourth step. Is located in. The second correction reading device 42 reads the second position information IP2 recorded on the second continuous sheet 32. The second correction reading device 42 is arranged on the upstream side of the confluence point C so that the second position information IP2 immediately before reaching the confluence point C can be read, for example, in the fourth step. The distance between the first correction reading device 41 and the merging point C and the distance between the second correction reading device 42 and the merging point C are substantially the same. The position information IP1 and IP2 immediately before reaching the confluence point C accurately reflect the position information IP of the bonded continuous sheet 30. Therefore, accurate position information IP1 and IP2 are acquired by the correction reading devices 41 and 42.

The operation of the quality monitoring system 10 will be described with reference to FIGS. 5 and 6.
The sheet manufacturing system 1 processes the continuous sheet 30 in the order of, for example, the first step, the second step, the fourth step, and the third step. In the sheet manufacturing system 1, the continuous sheets 31 and 32 are subjected to various processing and the like in the first step and the second step, respectively. Since the specific contents of the first step and the second step are the same as those of the first embodiment, the description thereof will be omitted.

As shown in FIG. 5, in the fourth step, the sheet manufacturing system 1 unwinds the first continuous sheet 31 and the second continuous sheet 32 from each third reel R3, respectively, and the third reel R3 to the fourth reel (not shown). The continuous sheet 30 is conveyed toward (omitted). The first correction reading device 41 reads the first position information IP1 immediately before the first continuous sheet 31 reaches the confluence point C, and outputs the acquired first position information IP1 to the third information generation unit 14C. The second correction reading device 42 reads the second position information IP2 just before the second continuous sheet 32 reaches the confluence point C, and outputs the acquired second position information IP2 to the third information generation unit 14C. Then, the first continuous sheet 31 and the second continuous sheet 32 are bonded to each other by the third processing apparatus 23, and the continuous sheet 30 having a two-layer structure is generated.

As shown in FIG. 6, the third information generation unit 14C is the first defective position information PF1 which is the defective position information PF of the first continuous sheet 31, and the second defective position information PF of the second continuous sheet 32. The defective position information PF2 is acquired, and the defective position table TF in which the first defective position information PF1 and the second defective position information PF2 are associated with each other is generated. Further, the third information generation unit 14C has the first position information IP1 and the second position information IP2 when the first position information IP1 and the second position information IP2 acquired by the correction reading devices 41 and 42 do not match. The first position information IP1 or the second position information IP2 is corrected so as to be consistent with. In one example, while the third information generation unit 14C generates a defect location table TF, correcting the first position information IP1 or second position information IP 2.

If the first position information IP1 and the second position information IP2 do not match, the correction reading devices 41 and 42 are in a state where one of the correction reading devices 41 and 42 has acquired the position information IP1 and IP2. This includes the case where the position information IP1 and IP2 acquired by the other of the above change. The change of the position information IP1 and IP2 is when the position information IP1 and IP2 acquired by the correction reading devices 41 and 42 change to another position information IP1 and IP2, or when the correction reading devices 41 and 42 change to the position information IP1. , The case where the position changes from the state where IP2 is acquired to the state where the position information IP1 and IP2 are not acquired, and the like are included. In one example, the pitch between the portions of the first continuous sheet 31 where the adjacent position information IP1 is recorded is different from the pitch between the portions of the second continuous sheet 32 where the adjacent position information IP2 is recorded. If this is the case, an event occurs in which the first position information IP1 and the second position information IP2 do not match. Such an event occurs when the continuous sheets 31 and 32 expand and contract due to the heat generated when the processing apparatus 20 performs processing.

The third information generation unit 14C adjusts the first position information IP1 and the second position information IP2 so that the portion where the first continuous sheet 31 and the second continuous sheet 32 meet for the first time is associated with each other, for example, and the defective position table TF. The second position information IP2 is corrected while generating. In one example, the third information generation unit 14C if not changed from the second position information IP2 is "8" when changed to "5" the first position information IP1 from "4", the first position information IP1 "5 The second position information IP2 corresponding to "" is corrected to be "8". After the third information generation unit 14C finishes generating the defective position table TF, the generated defective position table TF is stored in the server 15. The symbol “◯” in FIG. 6 indicates the position information IP of the poor quality portion F existing in the first continuous sheet 31 and the second continuous sheet 32.

In the third step, the sheet manufacturing system 1 unwinds the continuous sheet 30 from the fourth reel and removes the defective quality portion F by the removing device 16. The removing device 16 acquires the position information IP of one of the first continuous sheet 31 and the second continuous sheet 32. In one example, the removing device 16 reads the first position information IP1 recorded on the first continuous sheet 31 by a removing reading device, and based on the first position information IP1 and the defective position table TF, the quality defective portion F of the continuous sheet 30 is used. To remove. In one example, the portion of the continuous sheet 30 in which the first position information IP1 corresponds to "3", "7", "9", "11", "15", and "18" is removed. In this way, when the first position information IP1 and the second position information IP2 are corrected so as to match, the removal device 16 refers to one of the position information IPs of the first position information IP1 and the second position information IP2. Even so, the quality defect portion F of the continuous sheet 30 corresponding to each defect position information PF can be accurately detected.

The fifth step is, for example, a step carried out between the second step and the third step in a plurality of steps for processing the continuous sheet 30. In one example, the continuous sheet 30 is divided into three continuous sheets 30A to 30C by cutting the continuous sheet 30 by the fourth processing apparatus 24 at predetermined intervals in the lateral direction of the continuous sheet 30. The predetermined interval is predetermined based on the desired width of the sheet. The fourth processing apparatus 24 includes, for example, two cutters 24A.
