Description

The present invention relates to a laminated cutting method and a laminated cutting system, and particularly to a process for detecting defects.

When the fabric is rolled, if there are defects such as scratches on the fabric, incomplete parts will occur. Therefore, parts are replenished by overlapping extension (Patent Document 1). In the overlap spreading, the spreading is stopped near the position where there is a defect and the dough is cut. In addition to the drawbacks, cutting the dough also causes incomplete parts, so return to the most upstream position of the incomplete parts and stack new dough. This makes it possible to make up for incomplete parts.

In rolling, multiple pieces of dough are laminated, the parts laminate is cut out by cutting in the next process, and the parts laminate is picked up on a pickup table or the like. At this time, it is necessary to instruct the operator which part laminate has the incomplete part. It is also possible to remove the incomplete parts before sewing without removing the incomplete parts at the time of picking up.

Introducing other related prior arts. In Patent Document 2, information on parts is projected from a projector onto a laminate of fabrics on a pickup table. Then, the light projected from the projector moves in synchronization with the conveyor of the pickup table. In Patent Document 3, a label is attached to each part of the laminated body, and information for each part is displayed. However, these do not display information about incomplete parts.

If the incomplete parts are on the second and subsequent sheets from the top of the fabric laminate, even if you observe the fabric laminate, you cannot tell which part laminate has the incomplete parts. Therefore, it is necessary to make it possible for the operator to easily display which part laminate has incomplete parts.

An object of the present invention is to display to an operator in an easy-to-understand manner which part laminate contains incomplete parts with respect to the fabric laminate.

In the laminated cutting method of the present invention, the dough is repeatedly rolled and cut by the rolling rolling device to form a laminated dough, and when the defect of the fabric is detected by the defect sensor, the fabric is cut in the middle and the defect or the fabric is cut. Return to a position where the incomplete parts caused by the cut can be compensated and restart the extension. Then, at least when the cut fabric is picked up, the area including the incomplete parts or the position of the parts laminate including the incomplete parts is displayed on the surface of the fabric laminate.

In the laminated cutting system of the present invention, the dough is repeatedly rolled and cut to form a laminated dough, and when a defect of the fabric is detected by the defect sensor, the fabric is cut in the middle, which is caused by the defect or the cut of the fabric. Return to a position where the incomplete parts can be supplemented and restart the extension. The laminated cutting system of the present invention is a display means for displaying the position of an area containing incomplete parts or a part laminated body including incomplete parts on the surface of the laminated body of the fabric, at least when the cut fabric is picked up. It is equipped with.

In the present invention, the area including the incomplete parts or the position of the parts laminate including the incomplete parts is displayed on the surface of the fabric laminate. When displaying an area, the operator may roll up the parts laminate that overlaps the area and remove the incomplete parts. The same applies when displaying the position of the parts laminate including the incomplete parts.

At the time of cutting, the laminated body of the fabric may be covered with an airtight sheet. This sheet is generally transparent, and the light projected by the projector described later is applied to the surface of the airtight sheet, for example. The label may be attached to the surface of the airtight sheet, but it is preferably attached to the uppermost part of the parts laminate.

Preferably, a projector projects an area containing incomplete parts or a display indicating the position of the parts laminate containing incomplete parts onto the surface of the fabric laminate, or a labeler labels the surface of the fabric laminate. Paste in. Projectors and labelers can clearly indicate in which areas there are incomplete parts, or which are parts laminates containing incomplete parts.

Preferably, the projector projects the contour or contour of the parts laminate and the inside thereof, and also projects the area including the incomplete parts in a color different from that of the other areas. Since the area containing the incomplete part is illuminated with a different color from the other areas, the incomplete part can be easily identified.

Preferably, labels are attached by labelers to the upstream and downstream ends of the area containing the incomplete parts along the rolling direction. If the upstream end and the downstream end of the area including the incomplete part are labeled, the incomplete part is in the area sandwiched between the upstream end and the downstream end, so that the incomplete part can be easily identified. It is preferable to indicate on this label the number of incomplete parts in the laminated body by printing or the like.

Preferably, information indicating which number of fabrics in the parts laminate has incomplete parts is displayed on the surface of the fabric laminate. By doing so, the operator can know which part of which part laminate is to be removed without turning over the parts laminate. The number of fabrics is counted from the surface of the laminated body, for example, but may be counted from the bottom surface. Since the incomplete parts are on two adjacent fabrics, if you indicate the number of one of them and determine that the rest is below or above it, how many of the two fabrics are You just have to show if it is in your eyes.

Preferably, the number of parts to be removed is displayed for each part laminate including incomplete parts. Since there is a display for each part laminate, incomplete parts can be removed more easily.

In the figure showing an example in which light is projected by a projector, an overlapped area (an area including incomplete parts) is displayed, and there are incomplete parts on the third and fourth sheets from the surface of the laminated body. Display that. In the figure which shows the modification of the embodiment of FIG. 4, the number | number of incomplete parts from the surface is displayed for each part laminated body. In the figure showing the example of attaching the label, the label is attached to the upstream end and the downstream end of the overlapped area, and the label has incomplete parts on the third and fourth sheets from the surface of the laminate. Is displayed. In the figure which shows the modification of the embodiment of FIG. 6, a label is attached to the part laminated body including an incomplete part, and the number | number of incomplete parts from the surface is displayed for each part laminated body.

The following are the optimum examples for carrying out the invention.

1 to 7 show examples and modifications thereof. FIG. 1 shows the structure of the laminated cutting system 1 of the embodiment, and the cutting device 40 and the pickup table 42 are provided on the downstream side of the spreading device 2. The rolling table 4 is provided with a conveyor (not shown), and the laminated body 8 of the dough is carried out to the cutting device 40.

The extension head 5 reciprocates on the extension table 4. The extension head 5 includes a carriage 6, mounts the original fabric 7, operates under the control of the controller 9, and displays various information on the monitor 10. Reference numeral 12 is a traveling motor of the carriage 6. The dough 13 is unwound from the raw fabric 7 by the feeding roller 14 and conveyed by the conveyor 15. The defects are scratches on the fabric 13, unraveling of threads, and the like, and in the original fabric 7, marks such as tapes and tags are attached to the edges of the fabric at the defective positions. This mark is monitored by a defect sensor 16 such as a camera, a height sensor that detects a tag located higher than the cloth, a tape, and a photoelectric sensor that detects reflected light from the tag. When the camera is a defect sensor 16, the defect itself may be identified by image recognition from other parts of the fabric 13. Further, in order to identify the fabric 13 from the tape or tag indicating the defect, the image from the camera may be image-processed. When the mark or tag is detected, the position of the defect along the longitudinal direction of the fabric 13 is determined, and when the defect itself is detected, the position in the short side direction of the fabric 13 is determined in addition to the longitudinal position. The line sensor may be used as the defect sensor 16 to optically detect the defect itself of the fabric. Further, the end of the fabric is monitored by the end sensor 17.

The rolling head 5 includes a cutter unit 18, and the cutter unit 18 reciprocates in a direction perpendicular to the rolling direction of the dough 13, and cuts the dough 13 each time it reaches the end of the laminated body 8. The rolling direction (the direction in which the dough 13 is spread on the rolling table 8) is from the left to the right in FIG. When the defect sensor 16 detects a defect, it cuts the dough in the vicinity of the defect, for example, at the position of the defect or immediately downstream thereof. Preferably, the cutter unit 18 comprises a labeler 20 (FIG. 2) and affixes a label printed with information on defects to the uppermost fabric of the laminate. The labeler 20 may be provided separately from the cutter unit 18, for example, between the spreading device 2 and the cutting device 40.

The arrangement of the parts with respect to the laminated body 8 of the fabric is determined by the cutting data. The cutting device 40 sucks and fixes the laminated body 8 on a cutting table by covering the laminated body 8 with an airtight transparent sheet such as vinyl chloride, and cuts the laminated body 8 according to the cutting data. The laminated body 8 after cutting is carried out to the pickup table 42 by a conveyor (not shown). Then, preferably, a projector 44 is provided in the vicinity of the pickup table 42 to display which part of which part laminate has an incomplete part. The labeler 20 and the projector 44 are examples of display means, and one of them may be provided, and it is not necessary to provide both.

FIG. 2 shows a control system of the laminated cutting system 2. The traveling drive 25 controls the traveling motor 12, and the feeding drive 26 controls the feeding roller 14 and the conveyor 15. The defect sensor 16 detects the presence and position of defects in the fabric. When the labeler 20 is mounted on the cutter unit 18, a label is attached at a desired position. From the user input 27, the user inputs an instruction to the spreading device 2, and the communication interface 22 communicates with the cutting device 40 and the like. As a result, the positional relationship between the fabric and the cutting data, the position of the overlap area, and the like can be shared between the spreading device 2, the cutting device 40, the projector 44, and the like. The controller 9 includes a CPU 28 and a memory 30, and stores the cut data, the position where the incomplete part is located, the number of the incomplete part counted from the surface of the laminated body, and the like.

FIG. 3 shows the overlap processing at the time of defect detection, and in FIGS. 3 to 7, the right side of the figure is upstream in the spreading direction, and the left side is downstream in the spreading direction. Defects When the sensor 16 detects the tag 50 indicating that the fabric 13 is scratched, the spreading is stopped at the position of the cut lines L1-L1 immediately downstream of the tag 50, and the fabric 13 is cut. The extension head 5 returns to the upstream and stacks new fabric 13'from the overlap start line L2-L2. The process of stopping the rolling in the middle of the laminated body 8, cutting the dough 13, returning to the upstream in the rolling direction, and laminating the new dough 13'is called an overlap process.

The actual location of the defect is not known from the tag 50. Therefore, the part that overlaps with the cut lines L1-L1 in the lower layer fabric 13 is referred to as an incomplete part 46. Further, since the spreading is restarted from the lines L2-L2, a fragment of a part is generated in the upper layer fabric 13', and this is referred to as an incomplete part 47. The targets to be removed at the time of pickup are incomplete parts 46 and 47. For example, it is assumed that the dough 13'is on the third sheet from the top of the laminate 8 and the dough 13 is on the fourth sheet. In order to specify the number of incomplete parts 46 and 47, for example, it is specified as the third piece counting from the top of the laminated body 8, and based on this, the third and fourth incomplete parts are specified. Interpret that there is. Of course, it may be counted from the bottom of the laminated body 8 or displayed as the fourth piece, and it may be interpreted that there are incomplete parts in the fourth and third pieces from the top.

FIG. 4 shows an embodiment in which an incomplete part is designated by the projector 44. The projector 44 projects light on the contour or contour of each part laminate 48 on the laminate 8 and inside the overlap area 51 regardless of the inside and outside of the overlap area 51, facilitating pick-up. The projector 44 may move the projected image in synchronization with the conveyor of the pickup table 42, or the conveyor may be stopped during the pickup and the projected image may also be fixed. However, this process may not be performed and only the display of incomplete parts may be performed. The overlapping area 51 sandwiched between the lines L1-L1 and the line L2-L2 is projected with a different color or brightness from the other areas so as to be distinguished from the other areas. Based on this, the operator can see that there are incomplete parts in the parts laminated body that overlaps with the overlap area 51. It should be noted that light may be projected inside the contour or contour of the parts laminate in the area 51 instead of the entire overlap area 51. Further, in order to indicate that there are incomplete parts in the third and fourth layers of the laminated body 8, for example, the character "3" is projected. From the display of FIG. 4, the operator can understand that the third piece from the top of the laminated body 8 has the incomplete parts 49a and b, and the fourth piece has the incomplete parts 49c to f.

FIG. 5 shows a modified example that is an extension of the display of FIG. Display "3" (the third incomplete part from the top), "4" (the fourth incomplete part from the top), etc. on the surface of the parts laminate including the incomplete parts, and which part Shows which part of the laminate is an incomplete part.

FIG. 6 shows an example in which the label 52 is attached to the surface (top layer) of the laminated body 8. The position of the cut line L1-L1 and the position of the overlap start line L2-L2 are indicated by, for example, four labels 52. However, a total of two labels may be attached, one on the cut line L1-L1 and one on the overlap start line L2-L2. The parts laminate that overlaps the overlap area 51 sandwiched between the label 52 on the upstream side and the label 52 on the downstream side is a parts laminate including incomplete parts. In addition, characters such as "3" are printed on each label 52 or one of the labels as enlarged on the left side of FIG. 6, and the third and fourth labels are incomplete from the top, for example. Show that there are parts. By these, the range of the overlap area 51 is displayed, and the number of the incomplete parts in the laminated body 8 is displayed.

FIG. 7 shows a modified example in which the embodiment of FIG. 6 is further developed. Labels 54 and 55 printed with information about the parts laminate are attached to each parts laminate. A label 54 indicating the number of parts to be removed from the top of the laminated body is attached to the parts laminated body including the incomplete parts, and a label 55 indicating the number of the incomplete parts to be removed is attached to the other parts laminated body. paste. The label 55 may be omitted. Alternatively, the operator can be informed that the parts laminate includes incomplete parts simply by pasting the information on the defects on the target parts laminate without printing the information on the label 54. In the modified example of FIG. 7, by displaying the label 54, for example, an incomplete part can be removed immediately before sewing.
