Definitions
- the present invention relates to cutting of sheet material.
- Patent Document 1 Japanese Patent Application Laid-Open No. Hei 9 1 0 3 9 9 1 (USP 5 7 9 1 2 1 6)
- Patent Document 2 Japanese Patent Application Laid-Open No. 4 8-74 6 8 3 (US P 3 7 8 0 6 0 7)
- Patent Document 1 discloses that sheet material is efficiently cut while selectively using a round blade and a narrow blade having a shorter blade width.
- Patent Document 2 when cutting a sheet material having a low melting point such as Biel chloride, frictional heat is dissipated through the cutting blade so that the cutting blade is not removed from the sheet material, and the sheet material is melted. It is disclosed to prevent. That is, when the sheet material melts, the sheet material adheres to each other and the pattern such as a print falls, the skin of the sheet material becomes rough, and the cutting line becomes non-clear, etc. Prevent melting.
- An object of the present invention is to enable accurate cutting even when slippery sheet materials are stacked. Means to solve the problem
- the sheet material cutting method of the present invention when a plurality of sheet materials are stacked and fixed one on top of the other and cut into parts along a predetermined cutting line, the sewing margin of the parts or the part thereof is cut By locally heating the outside, the sheet materials are welded to each other up and down to fix the upper and lower sheet materials.
- the local heating is performed using a knife or perforation of a cutting head.
- the sheet material can be welded to each other by the friction between the knife and the sheet material by piercing the sheet material on which the knives are stacked and moving up and down at the same position.
- welding can be performed by piercing the sheet material and moving it up and down like a cutting knife.
- the local heating is performed at several power points per 1 part against the cutting line or its outer side.
- the local heating is performed at several points per part with respect to the seam allowance inside the cutting line.
- parts per part are, for example, about 2 to 10 parts, preferably about 3 to 6 parts per part.
- a plurality of sheet materials are vertically stacked and fixed, and when cutting into parts along a predetermined cutting line, cutting is performed so as to leave a plurality of places on the cutting line. It is characterized in that the uncut portion is cut later.
- the sheet material may be an air impermeable sheet material, for example, a sheet material such as chlorinated burle or synthetic leather (synthetic leather), or any other material subjected to an air impermeable process, etc. Is particularly effective.
- the air impermeability is not limited to the one which does not pass air at all, and is used in the meaning including one having low air permeability. Action and effect of the invention
- the sheet materials are welded to each other up and down or left uncut on the cutting line Can be cut accurately even with air-impermeable and slippery vinyl chloride and synthetic leather sheet materials.
- the sheet material can be easily fixed, and the suction force can be reduced when the sheet material is fixed by vacuum suction. Since the welding point is sewed on the cutting line or slightly outside or on the inside of the cutting line, welding can be performed without wrinkling the parts.
- welding can be performed easily with a normal cutting head by using a knife or perforation installed in the cutting head of the cutting device.
- the welding is carried out at several points per part, for example 2 to 10, preferably 3 to 6 places.
- the welding point shall be the seam of the cutting line at or slightly outside of the cutting line, or at the inside of the cutting line.
- a slightly outside area is, for example, an area of 5 mm or less at right angles to the cutting line.
- FIG. 1 is a plan view of the main part of the cutting device of the embodiment.
- FIG. 2 is a flowchart showing an algorithm of the cutting method of the embodiment.
- FIG. 3 is a view schematically showing an embodiment in which sheet materials are welded to each other along a cutting line or a slightly outer side thereof.
- FIG. 4 is a view schematically showing an embodiment in which the sheet material is welded to each other at the seam margin portion inside the cutting line.
- Fig. 5 shows a cut left on the cutting line, and the cut left at the end. It is a figure which shows an example typically.
- FIG. 6 is a view schematically showing a welding position between sheet materials in each of the embodiments of FIG. 3 and FIG. Example
- the cutting device 2 used in FIG. 1 is shown as follows: 4 is a table, 6 is a bristle fixed on the table 4 and is a bristle brush. Any member other than the blister 6 may be used as long as it has air permeability or an air suction hole and can suction and fix the sheet material placed thereon by the suction pump 16.
- a cutting head 8 travels on the arm 10 in the Y direction in FIG. 1 and the arm 10 travels in the X direction in FIG. 1 with respect to the rail 12. It can move.
- the head 8 is equipped with a knife or round blade for cutting sheet material etc.
- the head 8 moves the knife up and down to cut a stack of sheet material which is stacked on the bristles 6 and covered with a sheet such as a chlorinated burle.
- a sheet such as a chlorinated burle.
- the sheet materials be welded together with a knife or perforation as in the embodiment so that the second upper sheet material does not shift relative to the lower sheet material.
- a control unit 14 receives a cutting pattern, and controls the traveling of the head 8 in the X and Y directions and controls cutting, perforation, welding, and uncut.
- the cutting pattern may be generated by the cutting device 2 or by an external design device or the like.
- the numeral 16 is a suction pump, and the sheet material on the table 4 is vacuum-suctioned and fixed via the pristle 6.
- FIG. 2 shows the cutting algorithm in the embodiment.
- the method of fixing the sheet material is “welding” in which the sheet materials are welded to each other at the top and bottom, and a few-power cut left on the cutting line
- the selection of "welding”, “left uncut” and “others” can be made automatically by the control unit based on data such as the material of the sheet material and the cutting pattern even if manually input to the control unit. It may be selected.
- sheet materials stacked one on top of the other are welded to each other in the vicinity of the cutting line, that is, on the seam margin or cutting line inside the cutting line, or slightly outside the cutting line.
- a knife or perforation provided on the cutting head.
- a knife is pierced to a position where most of the stacked sheet materials are penetrated, and when moving up and down at the same position at high speed, the sheet materials are welded to each other vertically due to frictional heat.
- the perforations are rotated to dig through many of the stacked sheet material and rotated in that position for frictional heat welding.
- “many” means, for example, about 12 to 3/4 of the thickness of stacked sheets.
- the sheet materials be welded to each other by moving them up and down at high speed in a stuck state with the stacked sheet materials (step 3). Then perform cutting after welding (step 4). However, it is not necessary to weld all parts of the circumference of one part first, weld one place, cut one line, weld one place to the next line, for example, and cut this line May be If leaving a cut, change the cutting pattern and add the cut at several points on the cutting line (step 5). Then perform cutting (step 6) and finally cut the uncut part (step 7). Also, welding and uncut can be used in combination, in which case it is assumed that both welding and uncut are selected in the algorithm.
- Fig. 3 schematically shows an example in which welding points 26 are provided slightly outside the cutting line at several points.
- 20 is a bundle in which a plurality of sheet materials are stacked to have a thickness of about 2 cm to 5 cm, and an air impermeable sheet such as vinyl chloride or synthetic leather is used as the sheet material.
- an air impermeable sheet such as vinyl chloride or synthetic leather is used as the sheet material.
- the airtight vinyl chloride sheet 34 shown in FIG. Make vacuum suction more efficient.
- Reference numeral 2 denotes a knife, which is provided on a cutting head, and other members such as perforations may be used.
- a rod-like member or the like having a built-in heater may be provided in the cutting head, and the member may be welded up and down.
- the knife 22 moves the knife 22 up and down, and place welding points 26 at several places outside the cutting line, for example, four places. Then, when the knife 22 is pierced into the stacked sheet material and moved up and down at that position, the upper and lower sheet materials are welded to each other to fix the sheet material. Therefore, even if the upper and lower sheet materials can not be fixed only by suction with the suction pump, the sheet can not be fixed accurately because it is an air-impermeable sheet material.
- the welding point 26 is the outside of the part, and the distance from the cutting line is only 5 mm, so there is no need to crease other parts.
- the welding is performed, for example, before cutting, but welding and cutting may be alternately performed for each section (one line of cutting), such as welding, cutting, welding, cutting or the like.
- 28 is the pattern inside the part, which is the area inside the sewing allowance, which appears on the surface of the textile after sewing.
- FIG. 4 shows an example in which a welding point 26 is provided in the seam margin 30 inside the cutting line 24.
- welding point 2 6 is at sewing allowance 30 and is hidden by sewing so that no wrinkles are left on the product.
- FIG. 5 shows an example in which a cutting line 24 is provided with a cutting edge 32 at several places. It is preferable that a place to be left uncut is a place where the knife 22 is pulled up from the sheet material and turned around, such as a corner of a part. Further, the length along the cutting line 24 of the uncut 32 is preferably shorter than the width of the knife 22, ie, the length of the knife 22 in the cutting direction.
- the embodiment of FIG. 5 can be used in combination with the embodiments of FIGS. 3 and 4. For example, when other parts come immediately outside the cutting line 24, it is preferable to use the uncut 32 as shown in FIG. Also, using the embodiment of FIG. 3 and the embodiment of FIG.
- the welding point 26 is provided using the sewing allowance 30. It is good. Even if a knife 22 is used for cutting, if the number of sheets to be cut is small, a round blade (not shown) may be used, and the head is a knife, a punch, or the like during operation. Since tools such as circular blades can be selected, for example, it is possible to weld them with a knife or perforation and cut them with a circular blade.
- the sheet material in the bundle 20 is sucked through the air-permeable prism 6 and fixed on the table. Then, cover the bundle 20 with a gas-tight chloride sheet 34 to facilitate vacuum suction. If the sheet material of bundle 20 is air impervious, it is difficult to fix the sheet material only by vacuum suction, so use welding or left uncut. Then, welding and formation of uncut portions as well as cutting are collectively performed on the chloride sheet 34 and bundle 20. Therefore, at the time of welding, a knife 22 or a perforation is penetrated from the upper side to the vinyl chloride sheet 34, and the sheet materials of the lower bundle 20 are welded to each other.
- the sheet material is fixed to each other at the time of cutting by welding or uncut area by using a position which does not appear after sewing such as a cutting line or its outer side or a sewing margin, so that slip and sheet materials can be stacked accurately. It can be cut. Moreover, welding and uncut parts can be done with the parts provided in the head, and there is no need to add new parts.
