DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a defect position information collection system 1, a scheduled group system 2, and a defect removal system 3 according to an embodiment of the present invention. As shown in FIG. 1, the defect position information system 1 includes a printing machine 5, an inspection device 7, an assignment button 9, a machine side terminal device 11, a host computer 13, a database 15, and the like. The scheduled group system 2 includes a host computer 13 and a database 15. The defect removal system 3 includes a host computer 13, a database 15, a machine side terminal device 17, a defect removal device 19, and the like.
[0009]
The printing machine 5 performs printing on the roll paper 21. The inspection device 7 inspects for defects using a camera, a sensor, or the like. The assignment button 9 is pressed when the operator finds a defect.
[0010]
The machine side terminal device 11 collects the defect position information and the reliability sent from the printing machine 5, the inspection device 7, and the assignment button 9 and sends them to the host computer 13. The host computer 13 analyzes the information sent from the machine side terminal device 11 and stores it in the database 15.
[0011]
The machine side terminal device 17 sends the defect position information and reliability stored in the database 15 to the defect removal device 19. The defect removing device 19 automatically removes defects based on information sent from the machine side terminal device 17.
In FIG. 1, reference numeral 21 denotes roll paper, and 23, 25, and 27 denote defects on the roll paper 21.
[0012]
Next, operations of the defect position information collection system 1 and the defect removal system 3 will be described with reference to FIG.
[0013]
When the printing machine 5 or the inspection apparatus 7 recognizes a defect in the defect generation process (step 201), the printing machine 5 or the inspection apparatus 7 sets the defect positions and reliability of the defects 23 and 25 to the machine side terminal apparatus 11. send.
[0014]
Further, when the operator notices a defect (step 202) or when the operator feels that the defect is somewhat defective (step 203), the operator uses the assignment button 9 to send the defect position and reliability to the machine-side terminal device 11. .
[0015]
Here, the reliability information is represented by reliability A, B, and C, and the reliability A is a case where a defect position such as defect position information automatically collected from the printing machine 5 and the inspection apparatus 7 is clear. The reliability B is given when the defect position is ambiguous, such as the operator's visual inspection or the assignment of the defect position by judgment, and the reliability C is given when the start or end position of the defect is not known at all.
[0016]
In the case of defect position information collection by the printing machine 5, when the printing machine 5 starts an operation such as paper feed switching that causes a defect, the machine side terminal device 11 is notified of the start position information of the defect 23. When the printing machine 5 finishes the operation causing the failure, it notifies the machine side terminal device 11 of the end position information of the failure 23. In this case, since the information is directly given from the printing machine 5, the reliability of the start / end positions of the defect 23 is A.
[0017]
In the case of defect position information collection by the inspection apparatus 7, when the inspection apparatus 7 confirms the occurrence of the defect 25, the machine side terminal 11 is notified of the start position information of the defect 25. When the inspection device 7 confirms the end of the defect 25, it notifies the machine side terminal device 11 of the end position information of the defect 25. Since the inspection device 7 always monitors defects, the reliability of the start / end positions of the defects 25 is A.
[0018]
In the case of defect position information collection using the assignment button 9, when the operator confirms the occurrence of the defect 27, the start position of the defect 27 is set by the assignment button 9 or the machine side terminal device 11. Considering the time lag from the occurrence of the defect to the operator confirmation, the reliability of the start position of the defect 27 is B or C. When the operator confirms the end of the defect 27, the end position of the defect 27 is set by the assignment button 9 or the machine side terminal device 11. Since the operator continues the visual inspection up to the defect end position, the reliability of the end position of the defect 27 is A.
[0019]
The failure information 41 including such a failure position and reliability is sent to the machine-side terminal device 11 to the host computer 13, and the host computer 13 stores it in the database 15.
[0020]
FIG. 3 shows the defect information 41. The defect information 41 includes a roll paper position 43, a defect name 45, an index 47 indicating the state of the defect start / end position, a defect content 49, and the like. The defect content 49 includes a defect name 45a, a defect start position 51, a defect end position 53, and the like.
[0021]
The index 47 is represented by “X” when the reliability is A, “?” When the reliability is B, and “0” when the reliability is C. For example, in the case of a doctor line, since the defect start position 51 is roughly 100 m, the reliability is B, and the defect end position 53 is clearly 150 m, so the reliability is A. Therefore, the defect start / end position index 47 is “? X”.
[0022]
Next, the host computer 13 performs a scheduled group using the defect information 41 held in the database 15 (step 204).
That is, the host computer 13 uses the reliability to estimate the manufacturing instruction and the required time according to the operator skill and automation level of the defect removal process.
For example, a roll paper in which the ratio of the reliability A is high is attached to a defect removal apparatus having an automatic defect removal mechanism. In addition, roll paper having a high ratio of the reliability B and C required for visual inspection is attached to a semi-automatic defect removing apparatus.
[0023]
In addition, a roll having a high ratio of the reliability A is set in the defect removal process with low operator skill. On the contrary, a roll with a high ratio of the reliability B and C is set in the defect removal process with high operator skill.
Further, the time required for removing the defect in the defect removal process is calculated. For example, the removal time is estimated in the order of A <B <C.
In the defect removal process, the roll paper having a high ratio of reliability A is attached to a defect removal apparatus having an automatic defect removal mechanism (step 205). Next, in the case of reliability A (step 206), defect removal is started fully automatically (step 207).
[0024]
If the reliability is B (step 206), the automatic operation is performed up to the vicinity of the defect start position (step 208), the operator visually finds the defect start position (step 209), switches to the manual mode and starts defect removal (step 209). 210). When the reliability is C (step 206), the operator visually finds a defect start position (step 209), switches to the manual mode, and starts defect removal (step 210).
[0025]
Also, roll paper having a high ratio of the defect start / end positions of reliability B and C that require visual inspection is attached to a semi-automatic defect removal apparatus (step 211). When the reliability is B (step 212), a low skill operator or a high skill operator takes charge of a large number of units and manually removes defects (step 213). When the reliability is C (step 212), a highly skilled operator manually removes the defect (step 214).
[0026]
Here, the defect removal will be described in more detail. For example, at the start of defect removal, the following processing is performed. When the reliability of the defect start position is A, defect removal is automatically started at the defect start position.
[0027]
When the reliability of the defect start position is B, the machine is stopped before the defect start position, the machine takes action (siren, etc.), requests the operator to remove manually, the operator visually finds the defect start position, and manually The defect removal is started.
[0028]
If the reliability of the defect start position is C, if the reliability of the start position of the next defect is C, the machine is stopped immediately after the current defect removal is completed, and the machine causes an action (such as a siren) to remove the operator manually. When requested, the operator visually finds the defect start position and manually starts the defect removal.
[0029]
Further, at the end of defect removal, the following processing is performed. If the reliability of the defect end position is A, defect removal is automatically terminated at the defect end position.
[0030]
If the reliability of the defect end position is B, the machine is stopped before the defect end position, the machine causes an action (siren, etc.) to request the operator to remove it manually, and the operator visually finds the defect end position and manually Then, the defect removal is finished.
[0031]
When the defect end position reliability is C, the machine is stopped immediately after the start of the current defect removal, the machine takes action (siren, etc.), requests the operator to manually remove, the operator visually finds the defect end position, and manually Defect removal ends.
[0032]
As described above, according to the present embodiment, automatic removal is mainly performed on defects, so that the load on the operator is reduced. One operator can control a plurality of defect removal machines.
[0033]
【The invention's effect】
As described above in detail, according to the present invention, defects can be automatically removed as much as possible in the defect removal process, and an operator having the optimum skill is interposed to further reduce the time required for removing the defects. Calculation becomes easy.
