Description

  The present invention relates to a rewind inspection method, apparatus, and system for rewinding a roll-shaped winding sheet and visual inspection.

  When manufacturing roll-up sheets such as strip-shaped paper, synthetic resin film, aluminum foil, printing of patterns, etc., processing such as laminating, sheet defects are inspected in each manufacturing and processing process, and defects are detected. Is labeled or marked. In addition to the purpose of adjusting the strength and distortion of the winding and blowing off the solvent during processing, the operator must visually inspect the defective part with the label attached to the finished roll of the wound sheet. In order to perform the treatment, a rewind inspection device is used, and this device is provided with an inspection table equipped with illumination and an instrument for excising and bonding the defective portion as necessary to visually inspect the defective portion. It has been.

  However, such a label peels off if the adhesive strength is weak, causing secondary defects, and conversely, if the adhesive strength is increased, the removed sheet surface may peel off and become defective. In particular, food and medical bags require high levels of safety in terms of hygiene, so re-inspection of defects is important. In recent years, rewind inspection equipment is equipped with inspection means to check for defects. A re-examination is also done. In any case, every time a defective part is detected by labeling, marking, or re-inspection, the rewinding inspection device is stopped, the rewinding inspection device is rewound to the inspection table, the defect is visually checked, and the necessary measures are taken, and the inspection continues. (See, for example, paragraph [0003] of Patent Document 1).

  By the way, as described above, even if the rewinding operation is automatically stopped immediately after detecting the defective part with the label or the inspection means, it cannot be stopped suddenly in order to avoid distortion in the winding sheet, It is necessary to gradually decelerate and stop, and then reversely rotate to return the defective part to the inspection table. In recent years, the rewind inspection device has been increasingly speeded up as production efficiency has been demanded. For example, the rewind inspection apparatus is wound at 50 m or more until it stops after detecting a defect during rewinding at 300 m / min. Furthermore, the reverse rotation from there cannot be returned at high speed, but it must be slowly returned at constant speed. In other words, it takes 3 minutes or more to stop from the defect detection and to return to the visual inspection table, and after continuing the necessary work, it is continued. For example, if such a check is repeated 10 times and a serious defect is found after 30 minutes or more has been found, or more than a predetermined number of times such as excision and connection are required, the entire raw roll is discarded at that stage. The time taken for 30 minutes or more was wasted, which hindered the improvement in production efficiency due to the increase in speed.

And a rewind inspection system comprising defect detection means for detecting a defective portion and position specifying means for specifying the position of the detected defective portion on the winding sheet.

  According to the first or fourteenth invention, the winding sheet being rewinded is inspected over its entire length to detect all the defective portions and their positions on the sheet, and this is stored in the storage means to store a plurality of these. Since the image of the defective part is displayed as a list by the display means, the operator can grasp the degree of each detected defect to some extent by looking at the image of the defective part displayed in the list. Compared to what was confirmed by rewinding each time it was detected, for example, if the list shows that there are many serious defects that cannot be dealt with, the material will be disposed of without needing confirmation on the inspection table. In addition, it is possible to carry out inspection work efficiently by designating from a relatively serious defect by operating means and sequentially traveling to the inspection table for visual confirmation. In addition, when the winding sheet is cut into a plurality of sheets by a slitter, it is possible to grasp the entire defect from the list display even if the number of defects to be treated by excision and pasting is more than a predetermined number. Depending on the area that can be separated, it is possible to find an area that can be used, and it is possible to effectively use the entire raw material without discarding it, thereby eliminating waste and reducing costs.

  Also, after rewinding all the take-up sheets, display a list of all the defects that have been detected during the rewinding process, and move the designated defect to the inspection table. As long as one defect is detected, it is necessary to rewind the sheet that has been wound for a long distance and move it to the inspection table. Compared to what has been done, inspection can be performed much faster and more efficiently, and inspection efficiency can be improved while taking advantage of the production efficiency by increasing the winding speed of the rewind inspection apparatus. Furthermore, in the past, visual inspection of one defective part may have taken time as described above, and in actual operation, the inspection accuracy could not be increased beyond a certain level. List all detected defect images, and determine the defects that the operator should visually check and the defects that do not need to be visually checked. Then, specify only the necessary defective parts and check them sequentially. Therefore, even if the defect detection accuracy of the inspection means is further increased, it does not cause a big problem in work efficiency, and as a result, high-precision inspection can be performed and it can contribute to improvement of product quality.

  According to the second invention, information on the position of the winding sheet in the longitudinal direction is detected and stored as position information on the winding sheet of each defective portion, and automatically specified by the drive control unit based on this information. Since the defective portion is moved to the position of the inspection table, the defective portion is surely guided to the inspection table without any label or marking. In particular, in the present invention, the operator views the image of the defective portion on the display means in advance as described above. Therefore, it is easier and more efficient to specify the defective part on the sheet guided to the inspection table, and the inspection work can be performed efficiently, compared to the conventional case where there is no image of the defect position.

  According to the third invention, the position information further includes information on the position in the width direction of the winding sheet, and the image of each defective portion is displayed in a plurality of regions according to the position in the width direction by the display means. Since the list is displayed in the sorted state, it becomes easy for the operator to find the defective portion on the sheet guided to the inspection table, and the inspection work can be performed more efficiently. In addition, even if there are many serious defects as a whole sheet, it is possible to grasp the position in the width direction of the defect part displayed in a list, so if the original fabric is further divided into multiple areas by a slitter, the defect will be It is also possible to find an area that can be used in a small amount, and it is possible to effectively use the entire raw material without discarding it, thereby eliminating waste and reducing costs.

  According to the fourth invention, since the plurality of areas correspond to the areas that are divided into a plurality of columns by the slitter after or during the rewinding, the defect areas listed on the display means are displayed for each area. By looking at the situation, it is possible to easily identify and find a usable area with few defects depending on the area to be carved out, and it is possible to reduce costs by effectively using the entire original fabric without discarding it. Become.

  According to the fifteenth invention, the inspection means images the winding sheet being rewinded, and the defect detection means detects the defective portion by comparing the image captured by the imaging means with the master image. Since the position specifying means for specifying the position of the detected defective portion on the winding sheet is provided, the defect can be detected with high accuracy and the position can be specified.

  According to the fifth, sixth, sixteenth or seventeenth invention, the wound sheet after being printed or laminated in the printing apparatus or laminating apparatus is inspected over the entire length, and the defective portion and the position on the wound sheet are determined. All are detected and stored in the storage means, and the images of the plurality of defect portions are displayed as a list by the display means. Thus, as in the first or fourteenth invention, the images of the defect portions displayed in the list are viewed. The degree of each defect can be grasped to some extent, and it is rewound when there are many serious defects that cannot be dealt with, for example, compared with the conventional method of rewinding and checking with a rewind inspection device one by one. It is possible to determine the disposal in a short time before setting the material on the rewind inspection device without needing to check it. Also, it is necessary to run to the inspection table in order starting from a relatively serious defect. It is possible to efficiently perform inspection work by. In addition, when the winding sheet is cut into a plurality of sheets by a slitter, it is possible to grasp the entire defect from the list display even if the number of defects to be treated by excision and pasting is more than a predetermined number. It is possible to find a usable area depending on the area that can be separated, and it is possible to effectively use the entire raw material without discarding it, thereby eliminating waste and contributing to cost reduction.

  Conventionally, the defect inspection in the printing apparatus is judged in the printing process, and if the number of serious defects is a predetermined number or more, the entire raw fabric is discarded, and the defect inspection in the laminating measure is also judged in the laminating process. If the number exceeds the specified number, the entire fabric is discarded. If you look at each of the above areas, even if there are some areas that can be used, the entire area is discarded and wasteful, increasing the inspection accuracy in actual operation. However, in the present invention, it is possible to comprehensively determine the defects detected in each step later, effectively use the original fabric as much as possible, and eliminate waste, and It is possible to distinguish between defects that should be visually confirmed by the operator from the list of defect images and defects that do not need to be visually confirmed, and specify only the necessary defects. Even work Not a big problem on rate, results highly accurate inspection becomes feasible as can contribute to quality maintenance.

  Furthermore, while conventional defect inspection / determination has been completed for each process, the present invention makes a comprehensive judgment as described above, so it is possible to grasp company-wide where defects occurred in printing and lamination. Depending on the form of the defect detected by the laminating apparatus, the information can be fed back to the printing process to improve the printing apparatus. In addition, the inspection means can be omitted from the rewind inspection device, and the cost can be reduced.

  Similarly to the first or fourteenth invention, after the designated first defective portion is moved to the inspection table of the rewind inspection device, it is only necessary to move between the defective portions. Compared to unwinding and inspecting a sheet that has been wound for a long distance each time one is detected, inspection can be performed much faster and more efficiently, and production efficiency can be improved by increasing the winding speed of the rewind inspection device. It is possible to improve the efficiency of inspection while taking advantage of the merit.

  According to the seventh invention, similarly to the second invention, the defective part can be reliably guided to the inspection table without any label or marking, and the inspection work can be performed efficiently.

  According to the eighth invention, similarly to the third invention, even when there are many serious defects as a whole, the original fabric is further improved by looking at the position in the width direction of the defect portion displayed in the list on the display means. When cutting with a slitter, depending on the area to be cut, it is possible to find an area that can be used with few defects, and effectively use the original fabric that was discarded in each printing process and slitter process without discarding it. Thus, it is possible to eliminate waste and contribute to cost reduction.

  According to the ninth invention, as in the fourth invention, a plurality of areas correspond to areas which are divided into a plurality of columns by the slitter after rewinding or during rewinding. By looking at the situation of each defective area, it is possible to easily identify and find an area that has few defects depending on the area to be separated, and effectively uses the entire raw material without discarding it. This can contribute to cost reduction.

  According to the tenth or eighteenth invention, inspection can be performed efficiently by inspecting by both the printing apparatus and the laminating apparatus, displaying defect images of both, and making a comprehensive judgment.

  According to the eleventh or twelfth invention, the winding sheet to be printed or laminated is provided with identification information that can be read by the reading means provided in the rewind inspection device, and is detected by the inspection means. Since the image of the defective portion and the position on the winding sheet are stored in the storage unit together with the identification information attached to the winding sheet, the information on the original fabric based on such identification information in the rewind inspection device. Can be easily obtained, and the raw material can be easily managed.

  According to the thirteenth aspect, the winding sheet can be efficiently managed in the automatic warehouse based on the identification information.

  According to the nineteenth aspect, as in the fifteenth aspect, it is possible to detect a defect with high accuracy and specify the position thereof.
