[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device for mounting a plurality of long products such as aluminum extruded materials sequentially conveyed on a table on a pallet.

[0002]

2. Description of the Related Art Conventionally, a transfer device shown in FIG. 7 has been known as a transfer device for placing a plurality of aluminum extruded materials successively conveyed on a table on a pallet on the side of the table.

In the transfer device of FIG. 7, a plurality of aluminum extruded materials, that is, objects to be loaded (A) successively conveyed onto the table (50) are placed on a pallet (51) on the side of the table (50). Each time the object to be loaded (A) is transported, it is inserted below the object to be loaded (A) so as to be orthogonal to the longitudinal direction of the object to be loaded (A) at two locations. Corresponding to the number of the receiving plates (52) for supporting the loaded object (A) and the receiving plates (52) to be inserted, and two units are arranged, one above the table (50) and one above the pallet (51). A carriage (55) that reciprocates between the carriages (55) and a chuck device (54) attached to each carriage (55) so as to project downward and to be movable in the vertical direction. Each chuck device (54) is a receiving plate to be inserted.
Horizontal members (56) that are substantially parallel to (52), and the receiving plates (52) that are provided at both ends of the horizontal members so as to project downward and are separated from each other.
It is composed of a pair of holding arms (57) for holding and releasing.

In order to place the load (A) on the pallet (51) by this transfer device, first, the chuck device (54) of each carriage (55) is positioned above the table (50), The receiving plates (52) are inserted into the lower two places of the transported load (A) so as to be orthogonal to the longitudinal direction of the load (A) and symmetrically, and each holding arm (57) receives the respective load. Each chuck device (54) is lowered to a position where the plate (52) can be held. Next, each holding arm (57) holds each receiving plate (52), and each chucking device (54) is raised so that each receiving plate (52) supports the load (A). Then, each chuck device (54) is further raised, and then each carriage (55) is moved to above the pallet (51). Next, after lowering each chuck device (54), the receiving plate (52) is released, and the load (A) supported by the receiving plate (52).
On the pallet (51).

In order to place a plurality of articles (A) to be loaded on the pallet (51), each chuck device (54) is raised to move the table (5).
0) Move to the upper side and arrange the square pipes (53) for preventing the dent of the loaded object (A) on both ends of each receiving plate (52), and then repeat the above operation.

[0006]

In the above-mentioned conventional transfer device, the time required for transfer is longer than the time it takes for the object to be loaded to be transferred. Therefore, the productivity per hour of aluminum extruded material is improved. There was a problem that it could not be improved.

It is an object of the present invention to provide a transfer device capable of significantly reducing the time required for transferring a plurality of loaded objects on a pallet as compared with a conventional transfer device.
