  According to this configuration, the cutting unit does not come into contact with the plate material at the timing of changing the position. Therefore, even if the position of the cutting unit is changed while the plate material is placed on the cutting device, the plate material is not damaged or misaligned. Therefore, according to said structure, the position of a cutting | disconnection unit can be performed, without stopping the flow of a board | plate material.

  Further, in the above cutting apparatus, the transport unit includes a transport support unit that jets air to the lower surface of the plate member to support the plate member in a non-contact manner, a carry-out unit that pushes the plate member in a carry-out direction and carries it out. You may have. According to such a configuration, the plate material is supported in a non-contact manner not only by the cutting support portion of the cutting unit but also by the conveyance support portion of the conveyance unit, so that the plate material is further less likely to be damaged. Moreover, in said cutting device, although a board | plate material is supported by non-contact, since a board | plate material is extruded by the carrying-out part, a board | plate material can be reliably carried out from a cutting device.

  In the above-described cutting device, the carry-out unit may include an extruding member that contacts an edge opposite to the carrying-out direction of the plate member and an extruding drive unit that moves the extruding member in the carrying-out direction. Good. According to this structure, a board | plate material can be carried out from a cutting device, without a carrying-out part contacting the surface of a board | plate material.

  In the above-described cutting device, the transport unit may include a carry-in conveyor that carries in the plate material in contact with the lower surface of the plate material, and the carry-in conveyor may be positioned outside the cutting unit. . According to such a configuration, since the carry-in conveyor carries the plate material in a state where it is in contact with the lower surface of the plate material, it is possible to suppress the occurrence of positional deviation at the time of carry-in. Furthermore, since the carry-in conveyor is positioned outside the cutting unit, the carry-in conveyor comes into contact with a portion of the plate material that is cut off. That is, since a carry-in conveyor does not contact the part used as a product among board | plate materials, even if a board | plate material is damaged by a carry-in conveyor, a substantial problem will not arise.

  As described above, according to the above-described plate material cutting device, the cutting unit can be repositioned without stopping the flow of the plate material.
