Abstract

PURPOSE:To enable a work article to be relocated being inverted, by providing a pair of mounting frames integrally and vertically turnably with a horizontal supporting shaft serving as the center in a sliding structure and mounting holding fixtures to the pair of mounting frames. CONSTITUTION:The external shaft of a horizontal supporting shaft 12 is protruded by actuating a self-lock cylinder 24, and a work article A is held from its right and left by holding fixtures 14. If the work article A is confirmed to be held, a sliding structure 6 is moved upward by again actuating a fluid pressure cylinder 7. Simultaneously with the above action, a truck 4 is moved to a fixed position on a conveyer 2 and stopped by actuating an electric motor 34 through an endless chain 33. Next the horizontal supporting shaft 12 is rotated 90 deg. turning a mounting frame 13 to a degree of 90 deg. by actuating an endless chain 17 through a gear 15 or the like. Thus the work article A, which is turned 90 deg. from its vertical attitude as existing up to now, changes the attitude into a tumble down state. If the change of said attitude is completed, the sliding structure 6 is again lowered by the fluid pressure cylinder 7.

As can be understood from this, the holders <131) and (132) in Fig. 9 are examples in which the left and right sides have different configurations, but the right and left sides are not limited to the example shown in the figure and can have the same configuration. Needless to say, it's a good thing.

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), an arm (42) on the rectangular flat plate 1 is fixed to the lower end of this shaft (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 rack is moved forward and backward by a hydraulic cylinder (45). By moving back, the pinion gear (43
), the shaft body (40) is rotated to rotate the entire arm (42) and below. In addition, in this example, the top surface of the cart (4) is placed on the platform so that it is equal to or lower than the top surface of the frame frame (3), and the fluid pressure for moving the sliding body (6) up and down is Cylinder (7
) at a position below the bottom surface of the trolley (4), and place the guide frame (5
), and also set the upper limit of movement of the sliding body (6) to the trolley (4).
) A fluid pressure cylinder (46) set at a position below the top surface, and furthermore, the forward and backward movement of the truck (4) is accommodated within the upper and lower dimensions of the frame frame (3) (preferably a cell lock cylinder).
, adopts a drive structure in which a pinion gear (48) attached to the piston rod (47) is meshed with rack gears (49) and (50) on the mount frame (3) side and the truck (4) side. This makes it a convenient form for locations with low ceilings or limited space above the device. Furthermore, a horizontal support shaft (
12) is also used as a connecting shaft between the sliding body (6) and the rod (7a) of the cylinder (7) that moves it up and down.

(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, so it is possible to greatly improve work safety and improve efficiency. It has the advantage of being able to perform good reverse transfer, and also to be 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,
It 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 upper surface of the trolley (4) is placed at the same level as or lower than the upper surface of the frame (3), and the sliding body (6) is moved, which is attached to the lower surface of the trolley (4). If the upper limit is configured to be below the top surface of the trolley (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.
