  The thin processing apparatus includes a temporary placement table 2, a positioning unit, a transport device 8, an elevating device 9, and a processing table 10. The thin plate-shaped workpiece 1 is formed of a soft member. The temporary placing table 2 for the workpiece 1 has holes 20, 21, and 22 connected to a discharge and suction mechanism described later.

  The positioning portion is composed of positioning pins 3 and 4 and positioning mechanisms 5 and 6, and determines the position of the workpiece on the temporary placement table 2. That is, the positioning pin 3 serves as a reference in the X direction on the temporary table 2 and the positioning pin 4 serves as a reference in the Y direction. The positioning mechanism 5 in the X direction and the positioning mechanism 6 in the Y direction are not shown in the drawing. The workpiece 1 supplied to the temporary table 2 from the supply position of the workpiece is positioned.

  The conveying device 8 conveys the workpiece 1 held by the plate 7 that performs pressing and discharging and suction to the processing table 10. The elevating device 9 elevates and lowers the workpiece 1 held by a plate 7 that performs press and discharge and suction. The processing table 10 holds the workpiece 1 in the vicinity of two sides facing each other in the Y direction.

  The dimension h of the plate 7 that performs pressing and discharging and suction is shorter than the holding interval dimension H of the processing table 10 that holds the workpiece 1 on two opposite sides. The length in the Y direction of the workpiece 1 is longer than the holding interval dimension H of the processing table 10.

  FIG. 2 is a diagram showing a discharge and suction mechanism on the temporary table in the embodiment of the present invention. In FIG. 2, holes 20, 21, and 22 connected to the ejection and suction mechanism in the Y direction are arranged in three rows on the temporary table 2. Of the three rows, the center row is arranged at a position that substantially bisects the area defined by the four sides surrounding the workpiece 1. Each row includes a plurality of holes. For example, the workpiece 1 (not shown) is fixed to the temporary table 2 by sucking air from these holes. At this time, the workpiece 1 (not shown) is not sucked in the holes near the two sides facing each other in the Y direction of the workpiece 1 (for example, the holes 221 and 222 in the hole portion 22). Of the three rows of holes 20, 21, 22, at least one row of holes sucks the workpiece 1 (not shown).

  The plate 7 performs press and discharge and suction. The plate 7 is positioned by the positioning mechanism 5 in the X direction and the positioning mechanism 6 in the Y direction. Then, the workpiece 1 sucked by the temporary table 2 in the state described above is discharged and sucked after pressing to remove air pools and wrinkles.

  About the thin plate processing apparatus comprised as mentioned above, the operation | movement is demonstrated using FIG. 1A-FIG. 1E and FIG.

  FIG. 3 is a flowchart of the thin plate conveying method according to the embodiment of the present invention. In FIG. 3, the workpiece 1 is transported from the supply device (not shown) of the workpiece 1 to the temporary table 2 (S60). Next, the positioning pins 3 and 4 serving as the reference in the XY directions are operated (S61), and positioning is performed by the positioning mechanisms 5 and 6 while discharging from the holes 20, 21, and 22 connected to the discharge and suction mechanisms (S63). ). The workpiece 1 is not sucked in the holes near the two sides facing each other in the Y direction of the workpiece 1.

After fixing the workpiece 1 to the temporary placing table 2 in this way, the positioning mechanisms 3, 4, 5, 6 that have been operating return to the original position (S64, FIG. 1A).

  Next, the transport device 8 operates to move the plate 7 to the position of the temporary table 2. Then, the workpiece 1 sucked by the temporary table 2 in the above-described state is pressed by the plate 7 by moving the lifting device 9 downward (S65, FIG. 1B). The temporary placing table 2 and the plate 7 discharge each other, and after suctioning each other, discharge is performed again (S66). At this time, the air that has entered between the workpiece 1 and the temporary table 2 and between the workpiece 1 and the plate 7 is discharged. Further, the temporary table 2 performs discharge, the plate 7 performs suction, and the lifting device 9 is moved up to perform delivery (S67). The workpiece 1 is sucked into the plate 7 without wrinkles and air accumulation (FIG. 1C).

  Next, the conveying device 8 is operated, the lifting device 9 is moved down, and the workpiece 1 sucked by the plate 7 is conveyed to the processing table 10 (S68, FIG. 1D).

  Next, the workpiece 1 is held in the vicinity of the two sides facing each other in the Y direction, and the lifting device 9 is moved up to perform delivery on the processing table 10 (S69). At this time, the dimension h of the plate 7 attached to the conveying device 8 is shorter than the holding interval dimension H of the processing table 10 that holds the workpiece 1 on two opposite sides.
