Description

  The present invention relates to a sheet spreading device having a function of preventing sheet material from shrinking.

  In the manufacturing process of clothing, parts are created by cutting the fabric drawn from a roll-shaped material. A roll-shaped raw fabric is manufactured by being wound around a core material in a state where the fabric is subjected to a predetermined tension. Therefore, the fabric immediately after being pulled out of the original fabric has a residual tension, and the residual tension is eliminated as time passes, so that the fabric contracts. If the cutting is performed before the shrinkage of the dough is completed, there is a disadvantage that the parts obtained by the cutting are shrunk and the dimensions are distorted.

  In order to prevent such inconvenience, conventionally, the feeding mechanism for feeding the fabric from the original fabric, and feeding the fabric fed from the feeding mechanism in one direction while maintaining the state where the fabric hangs down at a fixed position by its own weight. A fabric characteristic stabilization promoting device has been proposed that includes a fabric feed mechanism and an air blowing mechanism that blows air onto a hanging portion of the fabric fed by the fabric feed mechanism (see Patent Document 1). This fabric property stabilization promoting device uses the air blowing mechanism to blow air to the drooping portion of the fabric, and the fabric is shrunk by the vibration generated thereby, and the shrinkage after cutting is performed. Try to prevent.

Japanese Patent Laid-Open No. 11-323721

  However, since the fabric characteristic stabilization promoting device of Patent Document 1 requires a space to hang down the fabric and blow wind, there is a problem of increasing the size. In addition, this fabric characteristic stabilization promoting device blows air from the original fabric by blowing air to the fabric with the air blowing mechanism while feeding the fabric in one direction while keeping the fabric hanging down by the fabric feeding mechanism. The length of stay in the device before discharging is relatively large. Therefore, there is a problem that it is difficult to perform the shrinkage prevention process when the fabric fed from the original fabric is relatively short due to reasons such as dealing with a small amount of production. In addition, since it takes time for the fabric property stabilization promoting device to feed out and discharge the fabric from the original fabric, it takes time to start the cutting after the raw fabric has been fed, extending the cycle time in the manufacture of clothing. There is an inconvenience.

  Accordingly, an object of the present invention is to provide a spreader device that has a shrinkage prevention function and can be miniaturized. It is another object of the present invention to provide a roll-back device capable of preventing shrinkage even with a relatively small amount of sheet material. It is another object of the present invention to provide a spreader device that can quickly perform the process from the loading of the original fabric to the spread.

In order to solve the above-mentioned problem, the spreader of the present invention is a spreader that pulls out a sheet material from a roll-shaped raw fabric and places it on a placement surface.
The sheet material is formed so as to be delivered to the placement surface by a delivery length larger than a withdrawal length drawn from the original fabric.

  According to the above configuration, when the sheet material is pulled out from the roll-shaped original fabric and placed on the placement surface, only the delivery length larger than the withdrawal length drawn from the original fabric is transferred to the placement surface. Sent out. Thereby, the sheet material pulled out in a state in which the tension at the time of manufacturing the original fabric remains is shrunk as the remaining tension is released until it is placed on the placement surface. Therefore, the sheet material can be placed on the placement surface in a state where shrinkage is prevented.

When viewed from the extending table 2, the upper end roller 8 moves in the direction indicated by the arrow P, and the conveying side 7a of the conveyor belt 7 stops, while the return side 7b moves in the direction of the arrow b3, which is the same as the arrow P. That is, the upper end roller 8 and the return side 7 b of the conveyor belt 7 both move toward one end side of the placement surface 20. As a result, the fabric 3 arranged on the transport side 7a of the conveyor belt 7 is moved down to the one end side together with the upper end roller 8 by the transport side 7a of the conveyor belt 7 supporting the fabric 3 being placed on the lower placement surface. 20 is lowered and placed. In the transfer operation, the clutch of the conveyor drive motor 19 is switched to the connection mode, the conveyor roller 16B is held in a non-rotatable state and is stopped, and the transport side 7a of the conveyor belt 7 becomes unmovable. On the other hand, the belt drive motor 23 is activated, the rotational force is input to the belt pulley 22B, and the connecting belt 21 is driven. When the lower plate 15 is pulled to the other end side by the connecting belt 21, the upper end roller 8 and the return side 7b of the conveyor belt 7 are moved to one end side as shown by an arrow P as shown in FIG. Driven.

  FIG. 8B is a diagram for explaining the transfer operation with the shrinkage prevention operation. The transfer operation accompanied by the shrinkage prevention operation differs from the case where only the transfer operation of FIG. 8A is performed in that the transport side 7a of the conveyor belt 7 is moved to the other end side of the mounting surface 20. . That is, in the transfer operation accompanied by the shrinkage prevention operation, the transport side 7a of the conveyor belt 7 is moved from one end of the mounting surface 20 toward the other end by a distance corresponding to the additional length set on the setting screen of FIG. At the same time, the upper end roller 8 rotates while moving from the other end of the placement surface 20 toward one end, and the return side 7b of the conveyor belt 7 moves from the other end of the placement surface 20 toward one end. When viewed from the spreading table 2, the upper end roller 8 moves in the direction indicated by the arrow P, and the conveying side 7a of the conveyor belt 7 moves in the direction of the arrow a3 opposite to the arrow P, while the return side 7b is indicated by the arrow. It moves in the direction of the same arrow b3 as P. That is, the transport side 7 a of the conveyor belt 7 moves toward the other end side of the placement surface 20, while the upper end roller 8 and the return side 7 b of the conveyor belt 7 both face toward one end side of the placement surface 20. Moving. As a result, the fabric 3 arranged on the conveying side 7a of the conveyor belt 7 is sent out by an extra length by the movement of the conveying side 7a of the conveyor belt 7, and the conveyor belt 7 supporting the fabric 3 is also sent. When the transfer side 7a of the first sheet is moved to the one end side together with the upper end roller 8, the transfer side 7a is lowered onto the lower mounting surface 20. As a result, the fabric 3 that has been pulled out from the original fabric 30 on the transport side 7a of the conveyor belt 7 and arranged with a pull-out length is sent to the placement surface 20 by the feed length with the additional length added and transferred. Is done.

  In the transfer operation accompanied by the shrinkage prevention operation, the control unit 100 controls the operations of the conveyor drive motor 19 and the belt drive motor 23 according to the set value of the additional length and the form of adding the additional length. That is, the control unit 100 operates the conveyor drive motor 19 to drive the conveyor roller 16 </ b> B, and moves the transport side 7 a of the conveyor belt 7. Here, when the form of addition of the additional length is continuous, the conveyor drive motor 19 drives the conveyor roller 16B at a rotation speed corresponding to the set additional length, and the conveyor side 7a of the conveyor belt 7 is continuously moved. Move to the other end side of the mounting surface 20. The moving speed of the conveyor side 7a of the conveyor belt 7 corresponds to the additional length set to be added to the drawing length when the moving speed of the upper end roller 8 and the return side 7b of the conveyor belt 7 is associated with the drawing length. Controlled to speed. On the other hand, when the form of addition of the additional length is intermittent, 1 is set every predetermined drawing length specified by the moving speed of the upper end roller 8 according to the number of additions set per unit length of the delivery length. The conveyor drive motor 19 is operated by the number of rotations corresponding to the additional length per turn. Thereby, the conveyor roller 16B is driven, and the conveyance side 7a of the conveyor belt 7 is intermittently moved to the other end side of the mounting surface 20. Regardless of whether the additional length is added continuously or intermittently, the control unit 100 operates the belt drive motor 23 to rotationally drive the belt pulley 22B, thereby causing the connecting belt 21 to move at a speed corresponding to the drawing length. Drive with. Thus, by pulling the lower plate 15 to the other end side by the connecting belt 21, the upper end roller 8 and the return side 7b of the conveyor belt 7 are moved at a speed corresponding to the drawing length as shown in FIG. As shown by the arrow P, it is driven to one end side. In this way, the upper end roller 8 and the return side 7b of the conveyor belt 7 are driven to one end side at a speed corresponding to the drawing length, and the transport side 7a of the conveyor belt 7 is driven to the other end side at a speed corresponding to the additional length. Thus, the fabric 3 on the transport side 7a can be sent from the conveyor 4 to the placement surface 20 to the placement surface 20 by a length obtained by adding an additional length to the drawing length.

  In the transfer operation accompanied by the shrinkage prevention operation, the control unit 100 controls the conveyor drive motor 19 and the belt drive motor 23 to control the operation of the conveyor belt 7 of the conveyor 4 and also controls the rotating body drive motor 77. The operation of the vibrator 71 is controlled. That is, when the conveyor 4 transfers the fabric 3 on the transport side 7a to the placement surface 20, the rotating body driving motor 77 is operated to rotate the rotating body 72, and the corners of the rotating body 72 are moved to the conveyor belt. 7 are sequentially brought into contact with the inner surface of the transport side 7a. Thereby, the conveyance side 7a of the conveyor belt 7 vibrates, this vibration is given to the fabric 3, and cancellation | release of the tension | tensile_strength which remained in the fabric 3 is accelerated | stimulated.

  FIGS. 9A and 9B are diagrams illustrating the transport operation. In the transport operation, the upper end roller 8 rotates in a state where the upper end roller 8 is stopped in the length direction of the placement surface 20, and the conveyor belt 7 is driven. FIG. 9A shows a state where the conveyor belt 7 is driven from the other end side of the placement surface 20 toward one end side. When viewed from the extending table 2, the conveying side 7a of the conveyor belt 7 moves in the direction of the arrow a4 from the other end to the one end, and the return side 7b in the direction of the arrow b4 from the one end to the other end. Moving. FIG. 9B shows a state in which the conveyor belt 7 is driven from one end side to the other end side of the placement surface 20. When viewed from the spreading table 2, the conveying side 7a of the conveyor belt 7 moves in the direction of the arrow a5 from the one end side to the other end side, and the return side 7b in the direction of the arrow b5 from the other end side to the one end side. Moving. The fabric 3 arranged on the conveyance side 7 a located on the placement surface 20 of the conveyor belt 7 is conveyed in the length direction of the placement surface 20 by the conveyance operation. In the transport operation, the clutch of the conveyor drive motor 19 is switched to the connection mode, the rotational force is input to the conveyor roller 16B, and the conveyor belt 7 is driven. On the other hand, the belt drive motor 23 is controlled to stop, the belt pulley 22B is held non-rotatable and stopped, and the connecting belt 21 cannot move. The conveyor side 7a of the conveyor belt 7 is driven from the upper end roller 8 toward the lower end roller 14 by the conveyor roller 16B, thereby being positioned on the placement surface 20 of the conveyor belt 7 as shown in FIG. The conveyance side 7 a is driven to one end side of the placement surface 20. On the other hand, the conveyance side 7a of the conveyor belt 7 is driven from the lower end roller 14 toward the upper end roller 8 by the conveyor roller 16B, and as shown in FIG. 9B, on the placement surface 20 of the conveyor belt 7. The transport side 7 a positioned is driven to the other end side of the placement surface 20.

  In the roll stacking apparatus 1 according to the present embodiment, the conveyor 4 performs the above-described movement operation, transfer operation, and transport operation, thereby transporting and transferring the fabric 3 drawn from the raw fabric 30 to the mounting surface 20 and stacking them. A body 38 is formed. FIG. 10 is a diagram illustrating 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 20. 10 (a1) and 10 (a2) show how the fabric 3 is placed on or near the surface of the placement surface 20, and FIGS. 10 (b1) and 10 (b2) show an intermediate level from the placement surface 20. FIG. FIGS. 10 (c1) and 10 (c2) show a state in which the fabric 3 is placed on the surface of the laminate 38 formed to have a thickness. FIGS. It shows how to place.

  When the formation of the laminated body 38 on the placement surface 20 is started, first, an original fabric drawing process for drawing the fabric 3 from the original 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 position in the length direction of the upper end roller 8 of the conveyor 4 may be from one end to the other end of the placement surface 20. 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 placing surface 20 as shown in FIG. 10 (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 20 or in the vicinity of the surface, the upper end roller 8 is lowered near the placement surface 20, 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 20. 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 20 is performed. That is, the conveyor 4 performs the transfer operation in a state where the fabric guide plate 12 is positioned at the stacking tip position A21, and the upper end roller 8 moves to one end side of the placement surface 20. When the conveyor 4 performs the transfer operation and all the fabrics 3 on the conveyor 4 are placed on the placement surface 20, as shown in FIG. 10 (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. In this placement process, when the conveyor 4 performs the transfer operation, the shrinkage prevention operation is performed. Thereby, since the residual tension can be eliminated when the fabric 3 placed on the placement surface 20 is transferred from the conveyor 4, the inconvenience that the fabric 3 placed on the placement surface 20 contracts can be prevented.

  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 20 while pulling out the fabric 3 from the original fabric 30. When the leading end of the fabric 3 moves to the stacking leading end position A21 in FIG. 10 (a1), the conveyor 4 stops the moving operation, and the continuous drawing process is completed. After the continuous drawing step, the above-described cutting step and the placement step with the shrinkage prevention operation are performed, and the fabric 3 is laminated on the fabric 3 placed on the placement surface 20 in the previous placement step. To do. In this placing step, the conveyor 4 performs the shrinkage prevention operation, whereby the fabric 3 can be stacked in a state where the residual tension is eliminated.

  10 (b1) and 10 (b2) show the state of the cutting process and the mounting process when the thickness of the laminate 38 reaches about half of the maximum value by repeating the continuous drawing process, the cutting process and the mounting process. FIG. As shown in FIG. 10 (b1), as the thickness of the laminated body 38 increases, the angle of the portion between the upper end roller 8 and the upper guide roller 9A of the conveyor belt 7 with respect to the horizontal plane is as shown in FIG. 10 (a1). It is decreasing than when. Thereby, the cutting position T2 by the cutter 27 is moved to one end side of the mounting surface 20 from the cutting position T1 in FIG. Even when the thickness of the stacked body 38 is about half of the maximum value, the stacking tip position B21 where the mounting process is started by performing the cutting process and the stacking base end position B22 where the mounting process is completed are shown in FIG. It is the same as the stacking tip position A21 and the stacking base end position A22 of (a1) and (a2).

  FIGS. 10C1 and 10C2 are views showing the cutting process and the mounting process when the thickness of the laminated body 38 reaches the maximum value. As shown in FIG. 10 (c1), when the thickness of the laminated body 38 reaches the increase value, the portion between the upper end roller 8 and the upper guide roller 9A of the conveyor belt 7 is horizontal. Thereby, the cutting position T3 by the cutter 27 has moved further to the one end side of the mounting surface 20 than the cutting position T2 in FIG. Even when the thickness of the stacked body 38 is the maximum value, the stacking tip position C21 where the cutting process is performed and the mounting process is started and the stacking base end position C22 where the mounting process is completed are shown in FIG. And (a2) is the same as the stacking tip position A21 and the stacking base position A22. Furthermore, since the part between the upper end roller 8 and the upper guide roller 9A of the conveyor belt 7 is horizontal, the cutting position T3 of the fabric 3 coincides with the lamination base end position C22.

  As described above, according to the roll stacking apparatus 1 of the present embodiment, when the fabric 3 is transferred from the conveyor 4 to the placement surface 20, only the feed length that is larger than the draw length drawn from the original fabric 30. While sending out to the mounting surface 20, the fabric 3 is vibrated with the vibrator 71. FIG. Therefore, before the fabric 3 is placed on the placement surface 20, the residual tension of the original fabric 30 is eliminated and the fabric 3 contracts. Therefore, the disadvantage that the fabric 3 contracts after being placed on the placement surface 20 can be effectively prevented. In addition, since the spread lamination apparatus 1 can perform lamination while eliminating the residual tension of the fabric 3, a laminated body 38 that does not shrink after cutting can be created. That is, by performing the cutting with the tension remaining on the fabric 3 of the laminated body 38, it is possible to effectively prevent the pattern piece obtained by the cutting from being contracted after the residual tension is eliminated.

  Moreover, according to the spread lamination apparatus 1 of this embodiment, the upper end roller 8 of the conveyor 4 is formed so that contact / separation drive is possible with respect to the mounting surface 20, and according to the thickness of the laminated body 38 on the mounting surface 20. Since the height of the upper end roller 8 is controlled, the conveyor belt 7 can be driven without interfering with the laminate 38 when the fabric 3 is transferred to the laminate 38. Further, the fabric 3 can be appropriately transferred from the conveyor belt 7 to the surface of the laminated body 38 without shifting. Moreover, since the upper end roller 8 is formed so that the distance from the mounting surface 20 can be adjusted, the surface of the laminated body 38 and the conveyor belt 7 can be formed with a simpler structure than moving up and down the mounting table of the spreading table. The distance between can be adjusted appropriately. As a result, with a simple structure, it is possible to prevent interference of the laminated body 38 with the conveyor belt 7 and displacement when the fabric 3 is transferred.

  In the above-described embodiment, the roll stacking apparatus 1 includes the vibrator 71 that vibrates the conveying side 7a of the conveyor belt 7, but the vibrator 71 may be omitted. That is, when the fabric 3 is sent out from the conveyor 4 to the placement surface 20, vibration by the vibrator 71 is not indispensable, and it may only be sent out to the placement surface 20 by a sending length obtained by adding an additional length to the drawing length.

  Further, the vibrator 71 rotationally drives a rotating body 72 provided on the upper side of the conveyor carriage 10 on the side of the original fabric support 6, and the corners of the rotating body 72 are sequentially moved to the conveying side 7 a of the conveyor belt 7. Although it was made to contact and vibrated to the fabric 3, the structure of the vibrator 71 is not limited to this, It can deform | transform into various forms. Further, the upper end roller 8 and the upper guide roller 9A of the conveyor 4 are formed so as to be able to vibrate, and when the fabric 3 is transferred over the upper end roller 8 and the upper guide roller 9A, the upper end roller 8 and the upper guide roller 9A may vibrate the fabric 3. That is, the rollers 8 and 9A on the side supporting the fabric 3 of the conveyor 4 may function as a vibrator.

  Further, in the above embodiment, when setting the shrinkage prevention operation, an additional length to be added to the draw length drawn by the conveyor 4 from the raw fabric 30 is set through the input unit 101. It is preferable to agree with the shrinkage amount. However, when the original fabric 30 is initially operated, the amount of shrinkage of the fabric 3 may be unknown. In this case, a plurality of types of additional lengths having different values are set, and each additional length is used to prevent shrinkage. Is transferred to the placement surface 20 and the amount of contraction of each of the fabrics 3 after the transfer is observed. Of the fabric 3 transferred to the transfer surface 20 by setting a plurality of additional lengths, an additional length that can prevent the original fabric 30 from contracting by adopting an additional length that does not substantially contract. Can be identified. As described above, the spread sheet laminating apparatus 1 according to the present embodiment can be set by changing the additional length. Therefore, an appropriate additional length that can prevent the shrinkage of the raw fabric 30 in which various tensions remain is provided. Can be identified.

  Moreover, in the said embodiment, the spread lamination apparatus 1 is equipped with the cutter unit 5 which can be driven in the surface parallel to the mounting surface 20, and cut | disconnecting position T1, T2, by the cutter 27 according to the thickness of the laminated body 38. Although T3 is adjusted, the cutter 27 may not be able to be driven in a plane parallel to the placement surface 20, and may operate only at a predetermined position in the length direction of the placement surface 20.

  Moreover, the spread lamination apparatus 1 may serve as a cutting apparatus, for example, the cutter unit 5 may be comprised so that the fabric 3 and the laminated body 38 on the mounting surface 20 may be cut.

  Moreover, in the said embodiment, although the anti-stacking apparatus 1 was provided with the cutter unit 5 which isolate | separates and operates with the conveyor 4, you may incorporate a cutter in the conveyor 4.
