The cutter moving device 50b includes a lifting device that moves the rotary cutter 50a up and down, and a slider device that moves the rotary cutter 50a in the width direction together with the lifting device.

  The transport unit 44 holds the mount M on which the green sheet 12 is placed and feeds it to a predetermined position, and the transfer unit 62 transports the mount M on which the green sheet 12 is placed from the paper feed unit 60. And a storage unit 64 for holding the mount M and the green sheet 12 transferred by the transfer unit 62.

  The paper feed unit 60 includes a tray 60a that holds the mount M, and a moving device 60b that supports the tray 60a and moves it to a predetermined position. The tray 60a is disposed so that the rear end of the mount M is positioned below the guide plate 54, and the moving device 60b is arranged so that the upper surface of the mount M stacked in the tray 60a is always positioned at a predetermined height. Moved by. Further, the moving device 60b can move the tray 60a forward and backward along the transport direction. A cutting portion 42 is attached to the tray 60a. For this reason, the cutting unit 42 can advance and retract integrally with the tray 60a (that is, the mount M) by the moving device 60b.

  The transfer unit 62 includes a suction pad 62a that sucks and holds the mount M held on the tray 60a, and a moving device 62b that moves the suction pad 62a forward and backward along the transport direction. At the position where the suction pad 62a is moved backward in the transport direction, the front end portion of the upper surface of the mount M is sucked and moved forward, whereby the mount M is transferred from the paper feed unit 60 to the storage unit 64.

  The accumulating unit 64 is a stack of the support arm 64a that supports the lower surface of the mount M transferred from the paper feed unit 60 by the transfer unit 62 and the mount M that is disposed in front of the paper feed unit 60 and carried by the support arm 64a.

Then, the support arm 64a supporting the mount M is separated in the width direction and retracted from the storage table 64b, whereby the mount M is dropped and stored on the storage table 64b.

  Next, a method for cutting and conveying a green sheet material to a desired size using the cutting and conveying apparatus 40 described above will be described.

  First, as shown in FIG. 5, by substantially reversing the traveling direction of the carrier sheet 24, the green sheet material 10 formed on the carrier sheet 24 is separated from the carrier sheet 24 and supplied to the cutting part 42. The green sheet material 10 is advanced and passed between the cutter 50 and the cutting board 52 that cut the green sheet material 10 in the width direction intersecting the forward direction (advance process).

When the green sheet material 10 is detached from the carrier sheet 24, the green sheet material 10 moves forward by the carrier sheet 24 while floating from the cutting board 52 by the air supplied from the blower 56. Further, the green sheet material 10 advanced forward from the cutting board 52 floats from the mount M by the air flowing on the cutting board 52 and between the cutting board 52 and the guide plate 54 and further advances. At this time, the green sheet material 10 may momentarily contact the cutting board 52, but air also flows below the cutting board 52, so that the green sheet material 10 adheres to the mount M or the like. It is almost impossible to move forward.
Note that while the green sheet material 10 is advanced, the cutting portion 42 and the tray 60a are retracted to a predetermined standby position.

  Next, as shown in FIG. 6, the green sheet material 10 advanced to a predetermined position is cut by the cutter 50 and the cutting board 52 and placed at a predetermined position on the mount M held by the tray 60a (cutting step). ). While the green sheet material 10 is cut, the rotary cutter 50a and the cutting board 52 are advanced in synchronization with the advance of the green sheet material 10. Thereby, while preventing the deformation | transformation of the front-end | tip of the green sheet material 10 before a cutting | disconnection, the green sheet material 10 can be cut | disconnected linearly along the width direction.

  In this cutting process, the blower 56 continues to blow with an air volume smaller than the air volume in the advance process while moving forward integrally with the cutter 50, the cutting board 52, and the guide plate 54. For this reason, in the cutting step, the green sheet material 10 gradually descends on the mount M from the front and adheres to the mount M. Further, since the tray 60a holding the mount M is also moved forward integrally with the cutting unit 42, the relative position between the green sheet material 10 and the mount M does not change, and the green sheet material 10 is at a predetermined position on the mount M. Mounted flat.

Then, the suction pad 62a is lowered on the mount M to which the cut green sheet 12 is attached, and the transfer pad 62 is driven to advance the suction pad 62a as shown in FIG. It conveys to the part 64.
At this time, the roll cutter 50a is raised so as not to come into contact with the green sheet material 10, and the cutting portion and the tray 60a advanced in the cutting process are retracted to the standby position, so that the advancement process and the cutting process can be continuously performed. .

As described above, the green sheet material 10 that is continuously supplied can be cut and the green sheet 12 having a predetermined size can be conveyed. That is, the green sheet material 10 is levitated by supplying air flowing forward on the cutting board and between the cutting board 52 and the guide plate 54, and passes between the cutter 50 and the cutting board 52. Can be moved forward reliably. Thereby, since the advanced green sheet material 10 can be cut at a predetermined position, the cut green sheet 12 can be easily transported on the mount M.
In addition, this invention is not limited to the thing of the structure of the said embodiment, In a detailed structure, it is possible to add a various change in the range which does not deviate from the meaning of this invention.
