The holders (131) and (132) shown in the figure are examples in which the left and right sides have different configurations, but it goes without saying that the left and right sides may have the same configuration, not just on the national side. .

Next, FIGS. 11 to 13 show still other embodiments, one of which is a mounting frame (13) for mounting a holder (14), which can be rotated 180 degrees around the vertical axis to perform processing. The second point is that the direction of the product can be changed is the mounting frame (3).
This is different from the previous embodiments in that the protrusion of other components above the top surface is suppressed as much as possible, and it can be conveniently installed especially in a place where indoor vertical space is limited. The specific structure will be explained.

In this example, first, the vertical shaft body (4) is attached to the cart (4).
0) is rotatably attached via a boss (41), a rectangular Senppabushi arm (42) is fixed to the lower end of this shaft body (40), and a guide frame (5) is suspended from this arm (42). Install consecutively. A pinion gear (43) is provided at the upper end of the shaft body (40), and a rank gear (44) provided on the truck (4) meshes with this, and the rank is moved forward and backward by a hydraulic cylinder (45). By moving back, the pinion gear (43)
The shaft body (40) is rotated through the arm (42) and the entire arm (42) and the rest are rotated. In addition, in this example,
A hydraulic cylinder (7) is mounted so that the upper surface of the trolley (4) is equal to or lower than the upper surface of the frame frame (3), and the hydraulic cylinder (7) is used to move the sliding body (6) up and down.
Place the guide frame (5) at a position below the bottom surface of the trolley (4).
At the same time, the upper limit of movement of the sliding body (6) is attached to the trolley (4).
a fluid pressure cylinder (46) (preferably a cell lock cylinder), which is set at a position below the top surface and further accommodates the forward and backward movement of the truck (4) within the upper and lower dimensions of the frame frame (3);
The pinion gear (
48), and by adopting a drive structure that meshes with the rack gears (49) and (50) on the frame frame (3) side and the trolley (4) side, it is possible to remove the space above the equipment from the ceiling. This is a convenient form for places with limited space. Furthermore, a horizontal support shaft (1) is provided to hold the mounting frame (13).
2) is a sliding body (6) and a cylinder that moves it up and down (
7) is also used as a connecting shaft with the rod (7a).

(Effects of the Invention) As described above, according to the present invention, it is possible to reversely transfer a processed product without requiring manual labor as in the past, and thus work safety can be greatly improved. It has the advantage of being able to carry out highly efficient counter-transfer, and also being able to effectively resolve the unexpected damage to processed products due to human error, thereby improving yield.

As shown in the embodiment, when the holder is inserted inside the workpiece and held by pushing action from the inside to the outside, the first embodiment shown in FIGS. 1 to 5 is used. Compared to the structure, the horizontal width of the mounting frame and the sliding frame that supports the holder can be significantly reduced, and the device can be made more compact.

In addition, there are two sliding bodies (61) and (62) on the trolley (4).
If these two sliding bodies are provided with mounting frames (131) and (132), respectively, so that the directions of rotation are symmetrical, the direction of reversal of the processed product can be easily changed,
This has the advantage of greatly contributing to improving work efficiency in subsequent processes.

Furthermore, if the mounting frame (13) can be rotated 180 degrees around the vertical axis, not only can the device be made more compact than described above, but the direction in which the workpiece is reversed can also be changed freely, making it easier to It has the advantage of contributing to a significant improvement in work efficiency in the process.

Furthermore, the top surface of the cart (4) is placed at the same level as or lower than the top surface of the frame (3), and a sliding body (6> movable body) is attached to the bottom surface of the cart (4). If the upper limit is set below the top surface of the truck (4), there is an advantage that it can be conveniently installed even if the ceiling is low or there is little space above the device.
