Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a press workpiece reversing device for reversing a press workpiece by 1800 degrees for the next press process.

The press workpiece reversing device is installed between presses in the press secondary processing line.

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. Tsuteshimara. For this reason, the stroke of the suction arm of the pressed product take-out and supply device is 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. This makes it 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 make the position of the workpiece the same before and after reversal.

An embodiment of the present invention will be described below with reference to the drawings.

Although not shown, the slide base 1 is fixed to a press bolster or the like by a mounting member, and has sliding guides 2 (FIG. 3) on both sides thereof. A sliding member 4 fixed to a slider 3 is slidably fitted into the sliding guide 2. A connecting plate 5 (FIG. 4) is fixed to the slider 3, and the connecting plate 5 is connected to a piston rod 7 of an air cylinder 6. The air cylinder 6 moves the slider 3 back and forth along the sliding guide 2, and constitutes an example of the linear drive section of the present invention. The air cylinder 6 is fixed to a mounting plate 8 provided on the slide base 1. A bearing plate 9 and a support plate 10 are fixed on the slider 3. One shaft portion 12 of the reversing plate 11 is rotatably supported by the bearing plate 9 . A rotary actuator 13 is attached to the support plate 10 , and a rotating shaft of the rotary actuator 13 rotatably passes through the support plate 10 and is connected to the other shaft portion 14 of the reversing plate 11 .
The shaft portion 12 and the shaft portion 14 are provided on both sides of the front end of the reversing plate 11, and a line connecting the shaft portion 12 and the shaft portion 14 becomes the rotation center of the reversing plate 11. The rotary actuator 13 rotates the reversing plate 11
It rotates 800 times reciprocatingly and constitutes an example of the reversing drive unit of the present invention. A jig plate 15 indicated by a two-dot chain line is fixed on the reversing plate 11.

The jig plate 15 has a flat plate shape in the figure, but various shapes can be used depending on the shape of the workpiece. On the slider 3, a support plate 16 indicated by a two-dot chain line is attached to a support member 17.
Fixed by The receiving plate 16 receives the workpiece to be reversed by the reversing plate 11, and like the jig plate 15, various shapes are used depending on the shape of the workpiece. The slide base 1 is located at the center position S of the workpiece as shown in FIG.

is placed between the breath and the press. The workpiece processed by the press in the previous process is carried onto the jig plate 15 by the suction arm of the press workpiece take-out and supply device.
The center of the processed product is the processed product center position S. matches. When the rotary actuator 13 operates to rotate the reversing plate 11 by 180 degrees in the direction of the arrow in FIG. 2, the workpiece on the jig plate 15 is reversed by 1800 degrees and placed on the receiving plate 16. Receiving plate 16
The center of the upper workpiece is located at the center position S after the reversal, and by reversing the workpiece, the workpiece moves by a distance L in the workpiece feeding direction (from left to right in FIG. 1). The present invention is characterized in that the slider 3 is moved back by this distance L by the operation of the air cylinder 6 after or during the reversal. The center of the workpiece is moved to the workpiece center position S by retracting the slider 3 by a distance L. In other words, the suction arm of the pressed workpiece take-out and supply device returns to the intermediate position between the press in the previous process and the press in the subsequent process, and the suction arm of the press workpiece take-out and supply device continues processing to the press in the subsequent process with the same stroke as when taking it out from the press in the previous process. We can supply products. When the rotary actuator 13 reverses the workpiece, it immediately returns to return the reversing plate 11 and the jig plate 15 to their original positions.

After the workpiece is supplied from the receiving plate 16 to the press in the subsequent process, the air cylinder 6 returns to return the slider 3 to the illustrated position. According to the present invention, a reversing plate is provided on the slider, and the slider is moved by the distance necessary to return the position of the workpiece that has changed due to the reversal by the reversing plate. The position of can be made the same before and after reversal.
