It is a flowchart figure of the web material conveyance method using the web material conveyance device of the said FIG. FIG. 5 is a simplified view of a conventional second web material transport apparatus.

  Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 3.

1 and 2 show a web material processing apparatus according to the present invention, which web material processing apparatus comprises
Web material transport means 1 for transporting the web material W from the upstream side to the downstream side, a processing unit 2 for processing the web material W transported by the web material transport means 1, and movement of the processing unit 2 The moving means 3 to be performed, the synchronizing means 4 for matching the transport speed of the web material W, and the moving speed of the processing unit 2 and the command means 5 for processing the web material W of the processing unit are provided. The web material W is a sheet-like material such as a film, non-ferrous metal, and non-woven fabric. The processing unit 2 is a unit that performs various processes such as coating, transfer, and cutting (die-cutting).

  The web material transport means 1 is constituted by a roller mechanism 10 having a plurality of rollers. That is, the unwinding roller 11 for winding the web material W and unwinding the web material W, the winding roller 12 for winding the web material W, and the processing unit for the web material W unwound from the unwinding roller 11 And a downstream roller group 18 for guiding the web material W processed by the processing unit 2 to the take-up roller 12. The upstream roller group 17 in this case has a pair of fixed rollers 30, 31 and a movable roller 32, and the downstream roller group 18 also has a pair of fixed rollers 33, 34 and a movable roller 35.

  A winding motor (rolling control motor) shown in the drawing is attached to the winding roller 11, and a winding motor (rolling control motor) shown in the drawing is attached to the winding roller 12. Therefore, the unwinding roller 11 rotates in the arrow A direction and the winding roller 12 rotates in the arrow B direction by the driving of the unwinding motor and the winding motor. For this reason, the web material W wound around the unwinding roller 11 is unwound as shown by an arrow C1, is guided (guided) by the upstream roller group 17, passes through the processing unit 2, and is downstream It is guided (guided) by the roller group 18 and taken up by the winding roller 12 as shown by the arrow C1.

  The processing unit 2 has an upper die 21, a lower die 22, and a connecting bar 23 connecting the upper die 21 and the lower die 22, and is disposed on the linear guide mechanism 24. For this reason, the processing unit 2 moves along the guide rails of the linear guide mechanism 24 from the upstream side to the downstream side in the web material transport direction and moves from the downstream side to the upstream side in the web material transport direction. It is possible.

  In this case, the processing unit 2 can reciprocate in the direction of the arrow C within the movement allowable range H set in advance. When the web material W is transported in the movement allowable range H, the upstream roller group 17 and the downstream roller group 18 transport the web material W in the horizontal direction.

  Further, the upper mold 21 of the processing unit 2 can be moved up and down as shown by an arrow D by a reciprocating mechanism such as a link mechanism, a cylinder mechanism, and a linear guide mechanism. At this time, the up and down movement of the upper die 21 is guided by the connecting bar 23 to move up and down. Then, the web material W can be processed (for example, cut (cut)) by lowering the upper mold 21.

  Further, as shown in FIG. 2, the web material transport means 1 includes speed detection means 25 for detecting the transport speed of the web material W. As the speed detection means 25, for example, a marker of the web material W is provided, and the transport speed of the web material W can be detected by detecting this marker. The marker detector may be contact type or non-contact type. Further, the conveyance speed of the web material W is detected from the number of rotations of the unwinding motor (unwinding control motor) of the unwinding roller 11 and the winding motor (winding control motor) of the winding roller 12. It may be

  Furthermore, this apparatus comprises speed detection means 26 for detecting the movement speed of the processing unit 2. As the speed detection means 26, as long as it is provided with the linear guide mechanism as described above, it can be configured by detecting the speed of the slider of this linear guide mechanism.

  As the synchronization means 4 for matching the transport speed of the web material W with the movement speed of the processing unit 2, the movement means 3 is controlled so as to match the transport speed of the processing material 2 with the conveyance speed of the web material W. In addition, when the speeds are synchronized, the command unit 5 causes the processing unit 2 to process the web material W.

  In addition, this apparatus is provided with reverse movement means 27. As the reverse direction moving means 27, the movable roller (guide roller) 32 of the upstream roller group 17 of the roller mechanism 10, the movable roller (guide roller) 35 of the downstream roller group 18 of the roller mechanism 10, and each movable roller 32 , 35 are provided from the downstream side to the upstream side in the web material transport direction. The moving mechanism includes a drive motor (for example, a servomotor) as a drive source, an interlocking mechanism for driving the movable rollers 32 and 35 by the drive of the drive source, and an upstream side from the downstream side in the web material transport direction. It can be configured by a guide mechanism or the like for moving it to the side.

  As the moving mechanism, a reciprocating mechanism such as a cylinder mechanism or a linear guide mechanism can be used. Furthermore, the moving mechanism may be one for the movable rollers 32 and 35 or may be attached to each of them. In this case, it is necessary to move the movable rollers 32 and 35 synchronously and simultaneously to set the moving speed and the moving range at the same time.

  In this processing apparatus, a speed detection means 28 is provided which detects the speed of the movable rollers 32, 35 moved by the reverse direction movement means 27. In addition, as this speed detection means 28, it can comprise by the means similar to the conventional structure used for the processing apparatus etc. which are shown in FIG.

  Next, a method of processing the web material W using the apparatus configured as described above will be described using the flowchart shown in FIG. The conveyance of the web material W is started (step S11), and during this conveyance, the processing unit 2 is moved in the direction of the arrow C1 shown in FIG. 1, that is, from the upstream side to the downstream side of the web material conveyance direction 33 and 35 are moved from the downstream side to the upstream side in the web material transport direction in the direction of the arrow C2 shown in FIG. 1 (step S12).

  Thereafter, the process proceeds to step S13, and it is determined whether the transport speed of the web material and the moving speed of the processing unit 2 have become the same speed (synchronized). At this time, in this embodiment, as shown in FIG. 4, the processing unit 2 is accelerated to half the speed of the web material W in an apparatus not having the reverse direction moving means 27. Along with the acceleration, the movable rollers 33 and 35 are accelerated from the downstream side to the upstream side in the web material conveyance direction so as to have the speed of the processing unit 2.

  As a result, the transport speed of the web material W and the processing unit 2 move from the upstream side to the downstream side in the web material transport direction at the same speed within the movement allowable range H of the processing unit 2. As described above, if synchronized in step S13, the process proceeds to step S14 and processing is performed in the processing unit 2 while the transport speed of the web material W and the moving speed of the processing unit 2 remain as they are.

  Thereafter, the process proceeds to step S15, and it is determined whether the processing step is to be ended. If it is determined that the process ends in step S15, the process ends, and if not, the processing unit 2 is returned to the initial position. That is, the processing unit 2 is moved from the downstream side to the upstream side in the web material transport direction and returned to the initial position (step S16). If it returns to an initial position in this way, it will return to step S11.

  As described above, in the apparatus provided with the reverse movement means 27, the speed of the processing unit 2 is set to the reverse movement means 27 in the relative relationship with the transfer speed of the web material W being conveyed with the processing unit 2. It can be slower than one without one. By moving the web material W being transported in the direction opposite to the transport direction, the vibration of the processing unit 2 can be suppressed to be relatively small when the processing unit 2 is adjusted to the transport speed of the web material W. Since the moving speed of the processing unit 2 can be suppressed, the speed synchronization between the web material W and the processing unit 2 can be improved. Thus, the processing accuracy can be improved. Furthermore, the movement distance of the processing unit 2 can be reduced, and the space of the entire apparatus can be set small despite the movement of the processing unit 2.

  By configuring the web material transport means 1 by the roller mechanism 10 having the plurality of rollers 30, 31, 32, 33, 34, 35, the web material W can be stably transported with a simple configuration. Moreover, the web material W is conveyed along the horizontal direction at least within the movement allowable range of the processing unit 2, and the movement direction of the processing unit 2 is also moved along the horizontal direction, and the controllability The movement mechanism of the processing unit 2 can be simplified.

  If the reverse direction moving means 27 is a mechanism for moving the guide rollers 32, 35 in the direction opposite to the direction of conveyance of the web material, the mechanism of the reverse direction moving means 27 can be simplified. When the mass of the processing unit 2 and the mass of the movable rollers 33 and 35 are the same, the moving speed of the processing unit 2 during conveyance can be stably set so as to be 1/2 of the conveyance speed of the web material W . By setting in this way, the moving speed of the processing unit 2 can be halved compared to the case where the web material W being conveyed is not moved in the direction opposite to the conveying direction, and stable processing is continued. can do. Further, by interlocking the processing unit 2 with the unit (movable rollers 32, 35 etc.) to be moved in the reverse direction, the reaction force can be canceled and the vibration component (element) of the opposing device can be reduced, and the web material is stable. Transport is possible.

  There is no limitation to the case where the moving speed of the processing unit 2 during transport is set to 1/2 of the transport speed of the web material W. For example, when the moving speed of the web material W is V1 and the moving speed V2 of the processing unit 2 is, it is sufficient that 0 <V2 / V1 <1. The mass of the processing unit 2 may be different from the mass of the movable rollers 33 and 35.

  The embodiment of the present invention has been described above, but the present invention can be variously modified without being limited to the embodiment. For example, as the processing unit 2, in the embodiment, the upper mold 21 and the lower are used. Although it was a press machine provided with the type | mold 22, and it cut | disconnected (mold removal), what is called a perforation etc. may be put. Further, the processing unit 2 may be a laser scanner, an image transfer device or the like. A laser scanner or the like scans the irradiated laser in a direction orthogonal to the transport direction of the web material W.

  The number of rollers of the upstream roller group 17 and the downstream roller group 18 in the web material transport apparatus is not limited to that shown in the example shown in the drawing, and increase and decrease are optional. In addition, as the mechanism for moving the processing unit 2 along the transport direction, the vertical movement mechanism of the upper die 21, and the movement mechanism of the movable rollers 33, 35, various known reciprocating mechanisms can be used.

  When matching the transport speed of the web material W with the moving speed from the upstream side to the downstream side of the processing unit 2, in the above embodiment, the processing unit 2 moves at this speed based on the transport speed of the web material W Although control was made to match the speed, conversely, the transport speed of the web material W may be matched on the basis of the moving speed of the processing unit 2. In addition, both the transport speed of the web material W and the moving speed of the processing unit 2 may be adjusted.
