Abstract
The invention provides a stack cutting method and a stack cutting system. If a defect of the cloth is detected by the defect sensor, the cloth is cut near the defect, and the cloth is returned to a position where the defect or the incomplete garment piece generated by the cutting of the cloth can be compensated, and the cloth is pulled again. The region including the incomplete parts or the position of the part laminate including the incomplete parts is displayed on the surface of the laminate of the cloth. The operator can easily know which panel is a laminate in which incomplete panels are present.
Description
Technical Field
The present invention relates to a stack trimming method and a stack trimming system, and more particularly to processing at the time of defect detection.
Background
When a defect such as a flaw is generated in the cloth during the drawing, an incomplete cut piece is generated. Therefore, the garment pieces are supplemented by overlapping the pull-ups (patent document 1). In the overlapping draw, the draw is stopped in the vicinity of the position having the defect, and the cloth is cut. In addition to the case where there is a defect, an incomplete cut piece is generated even when the cloth is cut, and therefore, the cloth is returned to the position on the most upstream side of the incomplete cut piece and a new cloth is laminated. This makes it possible to compensate for incomplete parts.
In the tenter, a plurality of pieces of cloth are stacked, and cut pieces are cut out in the next step, and the cut pieces are sorted on a sorting table or the like. In this case, the operator needs to instruct which of the parts of the layered body is not completely covered. In addition, the incomplete parts may be removed before sewing without removing the incomplete parts in sorting.
Other related art is described below. In patent document 2, information of parts is projected from a projector to a stack of cloths on a picking table. And, the projected light from the projector moves in synchronization with the conveyor of the picking table. In patent document 3, labels are attached to the respective parts of the laminate, and information on each part is displayed. However, these are not means for displaying information on incomplete parts.

Disclosure of Invention
If the incomplete panel is located after the 2 nd panel counted from above the laminate of the fabric, it is not known which panel the incomplete panel is present in, even if the laminate of the fabric is observed. Therefore, a technique is required that can display which panel of the layered body has incomplete panels so that an operator can easily know the presence of incomplete panels.
The invention aims to display which garment piece laminate contains incomplete garment pieces in a manner that an operator can easily know about a laminate of a fabric.
In the stack cutting method of the present invention, a step of pulling a cloth by a cloth pulling device and a step of cutting the cloth are repeated to form a stack of the cloth, and if a defect of the cloth is detected by a defect sensor, the cloth is cut halfway, and the cloth is returned to a position where an incomplete cut piece due to the defect or the cutting of the cloth can be compensated and the cloth pulling is restarted. When at least the cut fabric is sorted, a region including incomplete parts or a position of a part laminate including incomplete parts is displayed on a surface of a laminate of the fabric.
A stack cutting system of the present invention forms a stack of cloth by repeating a step of stretching the cloth and a step of cutting the cloth, cuts the cloth halfway if a defect of the cloth is detected by a defect sensor, returns to a position where an incomplete cut piece due to the defect or the cutting of the cloth can be compensated, and restarts the stretching. The stack-up cutting system of the present invention includes a display unit that displays, at least when the cut fabric is sorted, an area including incomplete parts or a position of a part stack including incomplete parts on a surface of a stack of the fabric.
In the present invention, the region including the incomplete parts or the position of the part laminate including the incomplete parts is displayed on the surface of the laminate of the fabric. When displaying the region, the operator may curl up the parts stacked on the region and remove the incomplete parts. The same applies to the case where the position of the part laminate including the incomplete parts is displayed.
In some cases, an airtight sheet is covered on the cloth laminate during cutting. The sheet is generally transparent, and is projected by a projector described later, for example, onto the surface of the airtight sheet. The label may be attached to the surface of the airtight sheet, but is preferably attached to the uppermost layer of the panel laminate.
Preferably, the display indicating the region including the incomplete parts or the position of the part stack including the incomplete parts is projected onto the surface of the stack of the cloth by a projector, or a label is attached to the surface of the stack of the cloth by a labeling machine. The projector or the labeling machine can clearly indicate which region has an incomplete part or which is a part laminate including an incomplete part.
Preferably, the projector projects light to the contour or contour of the panel laminate and the interior thereof, and projects light to a region including an incomplete panel in a color different from other regions. Since light is projected onto a region including an incomplete part in a color different from that of other regions, the incomplete part can be easily recognized.
Preferably, the labeling machine applies labels to the upstream end and the downstream end in the draw direction of the region including the incomplete part. If the upstream end and the downstream end of the region including the incomplete cut pieces are displayed by the label, the incomplete cut pieces are in the region sandwiched between the upstream end and the downstream end, and therefore the incomplete cut pieces can be easily recognized. In addition, it is preferable that incomplete parts are present on the second sheet of the laminate on the label by printing or the like.
Preferably, information indicating that an incomplete part exists in the second part of the layered body of parts is displayed on the surface of the layered body of parts. In this way, the operator can know which of the several pieces of the piece stacked body is to be removed without turning the piece stacked body. The number of the cloths is counted from the surface of the laminate, for example, but may be counted from the bottom. Since the incomplete cut piece has 2 adjacent pieces of cloth, if one piece of cloth is displayed and the other piece is determined to be a piece of cloth below or above the piece of cloth, the other piece of cloth of 2 pieces of cloth may be displayed.
Preferably, the removal of the second panel is performed for each panel of the panel laminate including the incomplete panels. Since the display is provided for each of the parts of the panel laminate, incomplete parts can be removed more easily.

Detailed Description
The following shows preferred embodiments for carrying out the invention.
[ examples ] A method for producing a compound
Fig. 1 to 7 show an embodiment and a modification thereof. Fig. 1 shows a configuration of a stack cutting system 1 according to an embodiment, and a cutting device 40 and a picking table 42 are provided downstream of a tenter device 2. The cloth stretching table 4 includes a conveyor, not shown, and conveys the cloth laminate 8 to the cutting device 40.
The cloth spreading head 5 reciprocates on the cloth spreading table 4. The cloth spreading head 5 includes a carriage 6 on which a roll cloth 7 is placed, and is operated under the control of a controller 9 to display various information on a monitor 10. Reference numeral 12 denotes a traveling motor of the carriage 6. The fabric 13 is discharged from the fabric roll 7 by the discharge roller 14 and conveyed by the conveyor 15. The wound cloth 7 is provided with a mark such as a tape or a label on the edge of the cloth at the position of the defect, taking the defect such as a flaw in the cloth 13 or a run-off of the yarn. The mark is monitored by a defect sensor 16 such as a camera, a height sensor for detecting a label positioned higher than the cloth, an adhesive tape, or a photoelectric sensor for detecting reflected light from the label. In the case of using a camera as the defect sensor 16, the defect itself may be identified by image recognition from another part of the cloth 13. In addition, in order to identify the cloth 13 and the tape and the label indicating the defect, an image from the camera may be subjected to image processing. When the mark or the label 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 direction position. It is also possible to use a line sensor as the defect sensor 16 to optically detect the defect itself of the cloth. In addition, the end of the cloth is monitored by an end sensor 17.
The cloth spreading head 5 includes a cutter unit 18, and the cutter unit 18 reciprocates in a direction perpendicular to the cloth spreading direction of the cloth 13 and cuts the cloth 13 each time the end of the laminated body 8 is reached. The cloth spreading direction (the direction in which the cloth 13 is spread on the cloth spreading table 8) is the left-right direction in fig. 1. When the defect sensor 16 detects a defect, the cloth is cut in the vicinity of the defect, for example, at a position where the defect exists or immediately downstream thereof. Preferably, the cutter unit 18 includes an applicator 20 (fig. 2), and a label on which information relating to a defect is printed is attached to the uppermost cloth of the laminate. The labeling machine 20 may be provided separately from the cutter unit 18, for example, between the tenter device 2 and the cutting device 40.
The arrangement of the parts with respect to the laminate 8 of the cloth is determined by the cutting data. The cutting device 40 covers the laminate 8 with an airtight transparent sheet such as vinyl chloride, and suctions and fixes the sheet to the cutting table, thereby cutting the laminate 8 according to the cutting data. The cut stacked body 8 is carried out to the picking table 42 by a conveyor not shown. It is also preferable that a projector 44 is provided near the sorting table 42 to display which of the parts of the part stack has an incomplete part in the second few. The labeling machine 20 and the projector 44 are examples of the display unit, and one of them may be provided, and it is not necessary to provide both of them.
Fig. 2 shows a control system of the stack cutting system 2, in which a traveling driver 25 controls the traveling motor 12, and a feeding driver 26 controls the feeding roller 14 and the conveyor 15. The defect sensor 16 detects the presence and position of a defect in the cloth. When the cutter unit 18 is mounted on the labeling machine 20, a label is attached to a desired position. The user inputs an instruction to the tenter device 2 from the user input unit 27, and the communication interface 22 communicates with the cutting device 40 and the like. This makes it possible to share the positional relationship between the cloth and the cut data, the position of the overlapping area, and the like among the cloth stretching device 2, the cutting device 40, the projector 44, and the like. The controller 9 includes a CPU28 and a memory 30, and stores cutting data, positions where incomplete parts exist, the number of incomplete parts counted from the surface of the laminate, and the like.
Fig. 3 shows the overlapping processing in the defect detection, and in fig. 3 to 7, the right side of the drawing is set as the upstream side in the cloth drawing direction, and the left side is set as the downstream side in the cloth drawing direction. When defect sensor 16 detects label 50 indicating that a defect is present in fabric 13, the pulling of the fabric is stopped at a position of cutting line L1-L1 immediately downstream of label 50, and fabric 13 is cut. The cloth-pulling head 5 returns upstream and a new cloth 13' is laminated from the overlap start line L2-L2. The step of stopping the tentering in the middle of the laminated body 8, cutting the fabric 13, returning to the upstream side in the tentering direction, and laminating a new fabric 13' is called an overlapping process.
The actual location of the defect is not known from the label 50. Therefore, the part of the lower layer fabric 13 overlapping the cut lines L1-L1 is defined as the incomplete part 46. Since the drawing is resumed from the line L2-L2, the upper layer fabric 13' is cut into pieces, and the pieces are incomplete pieces 47. The objects removed at the time of sorting are incomplete patches 46, 47. For example, the 3 rd existing cloth 13' counted from above the laminated body 8 is provided, and the 4 th existing cloth 13 is provided. In order to designate the presence of incomplete parts 46 and 47 in the several, for example, the 3 rd part counted from the upper side of the laminated body 8, it is interpreted that incomplete parts are present in the 3 rd and 4 th parts based on this. Of course, the number of the pieces counted from the lower side of the laminate 8 or the 4 th piece may be interpreted as the number of incomplete pieces counted from the upper side of the 4 th and 3 rd pieces.
Fig. 4 shows an example in which the incomplete cut pieces are specified by the projector 44. The projector 44 projects light to the contour or the contour and the inside of each part laminate 48 on the laminate 8 regardless of the inside and outside of the overlap region 51, and facilitates sorting. The projector 44 may move the projected image in synchronization with the conveyor of the sorting table 42, or may stop the conveyor during the sorting and fix the projected image. However, this process may not be performed, and only the incomplete parts may be displayed. The overlapping region 51 sandwiched by the lines L1-L1 and the lines L2-L2 can be distinguished from other regions by projecting light with a color or luminance changed from the other regions. Based on this, the operator knows that there are incomplete parts in the part stack overlapping the overlap region 51. The light may be projected not to the entire overlap area 51 but to the contour or the contour and the inside of the part stacked body in the area 51. In addition, for example, a character "3" is projected to indicate that an incomplete part exists in the 3 rd and 4 th parts counted from the top of the laminate 8. As can be understood from the display of fig. 4, the operator has incomplete panels 49a and b in the 3 rd panel and incomplete panels 49c to f in the 4 th panel counted from above the laminated body 8.
Fig. 5 shows a modification of the display of fig. 4. The display of "3" (incomplete parts exist in the 3 rd from the top) and "4" (incomplete parts exist in the 4 th from the top) is projected on the surface of the part laminate including the incomplete parts, and the incomplete parts exist in the several parts of the part laminate.
Fig. 6 shows an example in which a label 52 is attached to the surface (uppermost layer) of the laminate 8. The location of cut line L1-L1 and the location of the overlapping start line L2-L2 are shown, for example, with 4 tabs 52. However, 1 label may be attached to the cut line L1-L1, 1 label may be attached to the overlap start line L2-L2, and 2 labels may be attached in total. The panel laminate that overlaps the overlapping region 51 sandwiched by the upstream side label 52 and the downstream side label 52 is a panel laminate including incomplete panels. Further, characters such as "3" are printed on each label 52 or 1 label thereof as shown enlarged on the left side of fig. 6, and the incomplete parts are displayed on, for example, the 3 rd and 4 th labels counted from the top. This shows the range of the overlap region 51 and also shows that an incomplete part exists in the several second parts of the laminated body 8.
Fig. 7 shows a modification of the embodiment of fig. 6. Labels 54 and 55 printed with information on the parts laminates are attached to the parts laminates. Labels 54 showing the removal of the second part counted from above the laminate are attached to the part laminates including the incomplete parts, and labels 55 showing no indication relating to the incomplete parts are attached to the other part laminates. Note that the label 55 may be omitted. Alternatively, even if information relating to a defect is not printed on the label 54 and is attached only to the target panel laminate, the operator can be notified that the panel laminate includes an incomplete panel. In the modification of fig. 7, for example, an incomplete cut piece can be removed immediately before sewing by displaying the label 54.
