ことである。The suction arm of the press workpiece take-out and supply device takes out the workpiece from the press mold and transports it to the press workpiece reversing device, which inverts the workpiece 1800 degrees, and the suction arm transfers the workpiece to the next one. Conventional press workpiece reversing devices are configured to reverse the workpiece in the feed direction with one end of the workpiece as the center, so the position of the workpiece changes between before and after reversal. I get tired. For this reason, the stroke of the suction arm of the pressed product take-off and supply device must be set differently between the press in the previous process and the pressed product reversing device, and between the pressed product reversing device and the press in the subsequent process. In addition, it has been difficult to deal with cases where the dimensions of the workpiece in the feeding direction change or when reversing the workpiece becomes unnecessary. An object of the present invention is to provide a press workpiece reversing device that can keep the position of the workpiece unchanged before and after reversing, and can shorten the time required for reversing.

もできる。Before the workpiece 38 is transported, the workpiece receiving member 3 is in the lowered position, and the movable bodies 16, 16' are in the narrowly spaced position as shown in FIGS. 1 and 4. At this time, the adsorbers 26, 26' are oriented upward. In this state, the workpiece 38 is placed on the suction devices 26, 26' by the suction arm of the pressed workpiece take-out and supply device until it is directly above the jig 39 by lowering the suction arm. after that,
The suction devices 26, 26' operate to suction the front and rear ends of the workpiece 38. Next, the reversal drive air cylinder 35 operates,
Since the rack drive shaft 32 is rotated clockwise in FIG. 2 via the lever 34, the racks 2T, 2T' are rotated via the levers 30, 30', sliding shafts 31, 31' and links 29, 29'. 2. Move to the right in Figure 2 and remove the pinion 24,
24' rotates counterclockwise. The suction device holders 25, 25' and the suction devices 26, 26' are thus rotated through 180 DEG and the workpiece 38 is turned over. When the receiving member driving air cylinder 4 operates to raise the workpiece receiving member 3 and the jig 39 to the position shown on the right side of FIG.
' releases the suction, and the workpiece 38 is placed on the jig 39. Next, compressed air is supplied to the pneumatic passages 21 of the moving body driving air cylinders IT, IT', and the air passages 32 are opened to the atmosphere, so that the moving bodies 16, 16' move in the direction of increasing the distance between them. , the suction devices 26, 26' are moved from above the workpiece 38. In this state, the suction arm of the press workpiece take-out and supply device suctions the workpiece 38 and carries it away from the jig 39. The receiving member driving air cylinder 4, the movable body driving air cylinders IT, IT', and the reversing driving air cylinder 35 are returned to prepare for the next reversing operation. In the illustrated embodiment, the processed product 38 is
is reversed, and after the reversal, the adsorbers 26, 26' return to the upward position again.
When the workpiece 38 is turned over from the upward position to the downward position, it remains in that position and the next workpiece 38 is turned over.
It is also possible to adsorb the holder 8 with the adsorbers 26, 26' facing downward, and then turn it over when the suction device 26, 26' faces upward.
