Description

  The present invention relates to a spread lamination device that draws and laminates a sheet material such as a fabric from an original fabric and a cutting device including the same.

  Conventionally, as a cutting device for cutting a fabric to produce a pattern piece for clothing, a cutting table having a fabric placement surface and a cutter that incorporates a cutting blade and is driven in a plane direction on the placement surface. There is a plotter type cutting device having a head. This type of cutting device produces a pattern piece by driving the cutter head while operating the cutting blade based on the cutting data indicating the shape of the pattern piece, and cutting the fabric on the placement surface into a predetermined shape. Is configured to do.

  When producing a plurality of pattern pieces of the same shape with the above-mentioned cutting apparatus, it is possible to increase the cutting efficiency by forming a laminated body formed by laminating a plurality of fabrics on the mounting surface and cutting the laminated body. Has been done. In order to form a laminated body of fabrics on a placement surface, a spread laminate device is used in which the fabrics are cut out from a roll-shaped raw fabric and stacked on a support surface.

  The present inventor, as a spread lamination device, spans an endless conveyor belt between an upper end roller above the placement surface and a lower end roller below the placement surface, and the upper end roller and the lower end roller are The thing connected with the connection belt hung on the opposite side to the conveyor belt is proposed (refer patent document 1). The spread lamination apparatus draws out a fabric on a conveyor belt from an original fabric arranged on one end side of the placing surface, and cuts the drawn out fabric into a predetermined length. The cut fabric is transported to a placement position on the other end side of the placement surface by a conveyor belt, the transported fabric is transferred from the conveyor belt onto the placement surface, and the fabric is placed on the placement surface. Repeat the drawing process for pulling out the fabric from the original fabric, the cutting process for cutting the drawn fabric, the transporting process for transporting the cut fabric, and the mounting process for transferring from the conveyor belt onto the mounting surface. Thus, the fabrics are stacked to form a laminate.

  The roll-up laminating apparatus rotates in a state where the upper end roller stops moving in the fabric drawing process and the conveying process, and the conveyor belt conveying side moves to the other end side of the placing surface, while the conveyor belt returns. A transport operation is performed in which the side moves to one end side of the placement surface. In the fabric placement process, the upper end roller moves from the other end side of the placement surface to the one end side while rotating, and the conveyor belt transport side stops, while the return side of the conveyor belt is the other end side of the placement surface. The transfer operation that moves from one side to the other is performed. When the placement process is completed, the upper end roller and the conveyor belt transport side and return side move from one end side to the other end side of the placement surface while the upper end roller stops rotating. Return to the position where the drawing process is performed.

  When the thickness of the laminated body is increased by repeatedly transferring the fabric onto the placing surface, there is a possibility that the laminated body interferes with the conveyor belt moving above the placing surface. In order to prevent such inconvenience, if the distance between the placement surface and the conveyor belt is set to be large in advance, there arises a disadvantage that the fabric shifts when transferring from the conveyor belt to the placement surface. Therefore, in the above-described spread lamination apparatus, as the thickness of the laminate increases, the conveyor belt and the laminate on which the fabric is transferred from the conveyor belt are lowered by lowering the lamination table whose surface is the mounting surface. The distance between the surface and the surface is kept constant.

A body 38 is formed. FIG. 6 is a diagram for explaining the operation of the conveyor 4 and the cutter unit 5 according to the thickness of the stacked body 38 stacked on the mounting surface 1. 6 (a1) and 6 (a2) show how the fabric 3 is placed on or near the surface of the placement surface 1, and FIGS. 6 (b1) and 6 (b2) show an intermediate level from the placement surface 1. FIG. 6 (c1) and 6 (c2) show how the fabric 3 is placed on the surface of the laminated body 38 formed in the thickness. FIGS. 6 (c1) and (c2) show the cloth 3 placed on the surface of the laminated body 38 formed in the substantially maximum thickness. It shows how to place.

  When the formation of the laminated body 38 on the placement surface 1 is started, first, a raw fabric drawing process for drawing the fabric 3 from the raw fabric 30 onto the conveyor belt 7 is performed. In the original fabric drawing process, the leading end of the fabric 3 is manually pulled out from the original fabric 30 and placed on the surface near one end of the conveyor side 7a of the conveyor belt 7. At this time, the length direction position of the upper end roller 8 of the conveyor 4 may be any from one end to the other end of the placement surface 1. When the leading end of the fabric 3 is placed on the surface of the conveyor belt 7, the conveyor 4 performs a transport operation, and the leading end of the fabric 3 is transported to the fabric guide plate 12 at the other end of the conveyor 4, and the original is accompanied accordingly. The fabric 3 is pulled out from the opposite side 30, and the fabric 3 is laid on the surface of the conveyor belt 7 on the conveying side 7a. When the tip of the fabric 3 is conveyed to the fabric guide plate 12, the presser plate 13 is driven toward the surface of the fabric guide plate 12, and the tip of the fabric 3 is sandwiched and fixed by the fabric guide plate 12 and the presser plate 13. Is done. When the front end of the fabric 3 is fixed to the fabric guide plate 12, the conveyor 4 performs a moving operation, and the front end of the fabric guide plate 12 is placed on the placement surface 1 as shown in FIG. 6 (a1). 38 is moved to the stacking tip position A21 which is the other end edge of the position where the position 38 is to be formed. In addition, before fixing the front-end | tip part of the fabric 3 to the fabric guide plate 12, in order to remove defective parts, such as pattern matching and fraying, you may cut | disconnect the edge part of the fabric 3 with the cutter unit 5. FIG. Further, in the original fabric drawing process, the fabric guide plate 12 is arranged at the stacking tip position A21, and the front end portion of the fabric 3 pulled out from the original fabric 30 is manually transported to the fabric guide plate 12 and fixed. Also good. That is, the conveyance operation of the conveyor 4 may not be performed.

  Then, the cutting process which cut | disconnects the fabric 3 on the conveyor 4 at the cutting position T1 with the cutter 27 of the cutter unit 5 is performed, and the fabric 3 is cut off from the raw fabric 30. When the fabric 3 is placed on the surface of the placement surface 1 or in the vicinity of the surface, the upper end roller 8 is lowered near the placement surface 1, so that the upper end of the conveyor belt 7 as shown in FIG. A portion between the roller 8 and the upper guide roller 9 </ b> A is inclined with respect to the placement surface 1. The cutter unit is determined by the sum of the length of the fabric 3 placed on the inclined portion of the conveyor belt 7 and the length of the fabric placed on the horizontal portion on one end side of the upper guide roller 9A of the conveyor belt 7. 5 is calculated, and the cutting position by the cutter 27 is determined. In the cutting process, after the fabric 3 is separated from the original fabric 30, the operator adjusts the shape and position of the fabric 3 on the conveyor belt 7 by the operator for adjusting the pattern of the fabric 3 and adjusting the distortion as necessary. It is done.

  After the cutting step, a placement step of placing the fabric 3 on the conveyor 4 on the placement surface 1 is performed. That is, the conveyor 4 performs a transfer operation in a state where the fabric guide plate 12 is located at the stacking tip position A21, and the upper end roller 8 moves to one end side of the placement surface 1. When the conveyor 4 performs the transfer operation and all the fabrics 3 on the conveyor 4 are placed on the placement surface 1, as shown in FIG. 6 (a2), the fabric guide plate 12 is moved from the stacking tip position A21. It reaches the lamination base end position A22 separated by one length on the length side of the laminated body. When the fabric guide plate 12 reaches the lamination base end position A22 and the transfer of the fabric 3 is completed, the transfer operation of the conveyor 4 is stopped, and the placement process is completed. When the placing step is completed, the height direction position of the upper plate 11 is raised by the thickness of the transferred fabric 3.

  After the placing process, the fabric guide plate 12 returns the conveyor 4 positioned at the stacking base end position A22 to the stacking tip position A21, and subsequently performs a continuous drawing process of pulling out the cloth 3 to be stacked from the raw fabric 30. The transfer of the fabric 3 is completed, and the tip of the fabric 3 to be subsequently laminated is located on the fabric guide plate 12 of the conveyor 4 located at the lamination base end position A22. In this state, the conveyor 4 performs a moving operation, and moves the fabric 3 to the other end side of the placement surface 1 while pulling out the fabric 3 from the original fabric 30. When the front end of the fabric 3 moves to the stacking front end position A21 in FIG. 6 (a1), the conveyor 4 stops the moving operation, and the continuous drawing process is completed. After the continuous drawing process, the above-described cutting process and placing process are performed, and the fabric 3 is laminated on the cloth 3 placed on the placing surface 1 in the previous placing process.
