2. Description of the Related Art An example of a conventional conveying system for sending or unloading a sheet metal material to a machine tool for bending or the like is shown in FIG.
This is shown in the explanatory diagram of FIG. 7.

FIG. 6 is a plan view showing the arrangement of the respective constituent parts. FIG. 7 is a side view from the AA portion of FIG.

In this conventional example, there are seven pallets 11 for temporarily accumulating sheet metal materials (workpieces) 1. Above the predetermined positions (stations) of the seven pallets 11, the work pieces 1 are placed.
There is a single-sheet pick-up loader 13 that picks up one by one and conveys it to the machine tool side (line side) 12.

A guide rail 15 is provided so that the loading / unloading carriage 14 can move laterally of the seven pallets in parallel with the pallet station row.

The loading / unloading carriage 14 is constructed so that the sheet metal materials 1 are loaded and fed to the pallet 11 or the sheet metal materials 1 are unloaded from the pallet 11.

[0007]

However, in the above conventional system configuration, the loading / unloading carriage 14 is provided on the side of the arrangement row of the plurality of pallets 11 for temporarily accumulating the plate-shaped sheet metal material (work) 1. It requires a traveling space to move, the floor area for the equipment is large, and the cost of the building and the land increases, which is difficult.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a space-saving pallet transfer system in which the installation space is made efficient and reduced.

[0009]

Therefore, the space-saving pallet transfer system according to the present invention achieves the above object by the following constitution.

A space-saving pallet transfer system for loading a pallet loaded with sheet metal materials on a carrier truck and supplying it to the sheet metal carrier platform, or unloading the sheet metal material by the carrier truck, at a specific location on the mounting table. A pallet receiver is formed, and the carrier truck is a lifter truck capable of ascending a portion other than the pallet receiver of the mounting table, and the movement route of the lifter truck is a predetermined arrangement position of the plurality of sheet metal material loading platforms. A space-saving pallet transfer system characterized in that a guide rail is provided so that the lifter truck can move in the lower part of the pallet.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The space-saving pallet transfer system according to the present invention provides a system for installing a system in which a transfer carriage for transferring a sheet metal material moves a lower part of a predetermined arrangement position of a plurality of sheet metal material loading bases. For example, it is an embodiment of halving.

This embodiment will be described in detail with reference to examples.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the space-saving pallet transfer system of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view showing the main construction of an embodiment of the present invention. FIG. 2 is a side view for explaining the same embodiment.

This embodiment has a plurality of sheet metal material loading platforms (pallets) 2 for temporarily loading sheet metal materials (workpieces) 1 to be conveyed to a machine tool, and the work pieces 1 are placed on the selected pallet 2.
Loaded on the transfer carriage 3 and supplied to the mounting table 10, or the work 1 is transferred from the pallet 2 to the transfer carriage 3
It is a space-saving pallet transfer system that can be loaded onto and taken out of.

As shown in FIG. 2, the transport carriage 3 is a lifter carriage capable of raising the loading portion, and the guide rails are arranged so that the lifter carriage 3 moves under the predetermined arrangement positions of the plurality of pallets 2. 4 is provided.

A single-loading loader 5 picks up one work from the pallet 2 and conveys it.

FIG. 3 is an explanatory view of the pallet 2 portion.

The pallet 2 has two shafts 7 projecting from the left and right side surfaces thereof. As shown in FIG.
By engaging with the pallet receiver 8 provided on the mounting table 10, the pallet 2 is stably held at a predetermined position (station). When the position of the pallet 2 is displaced, as shown in FIG. 3B, the shaft 7 can be displaced by moving the lifter truck 3 from the pallet receiver 8 provided on the mounting table 10.

FIG. 4 is a diagram for explaining the operation of this embodiment.

As shown in FIG. 4, the work is supplied to the mounting table 10 by loading the pallet 2 having the work 1 loaded on the lifter truck 3 and moving to the designated pallet 2 entry / exit position to stop. As shown in FIG. 4, when the lifter is lifted, the pins are evaded and the pallet 2 is lifted from the mounting table 10. Then, when the lifter carriage 3 is moved to a position where the shaft 7 of the pallet 2 and the pallet receiver 8 meet and the lifter is lowered, the pallet 2 is supplied to the mounting table 10.

The work is taken out from the pallet 2 as shown in FIG.
4, the lifter truck 3 is moved to the designated position, the lifter is raised, the lifter is retracted to the designated position in order to avoid the pin, and the lifter is lowered as shown in FIG.
The lifter truck 3 is moved to the loading / unloading position.

With the above-described structure and operation, the lifter truck 3 moves the lower part of the pallet 2 so that it does not require a large independent moving site, and the work 1 is loaded and supplied to the pallet 2. Alternatively, the work 1 can be received from the pallet 2 and carried out.

(Other Embodiments) An embodiment will be described with reference to FIG. 5 which is characterized in that the lifter truck 3 moves the lifter downward from the pallet position in the above embodiment.

As shown in FIG. 5, the lifter truck 3 is
Raise the lifter and open the pallet receiver 9. Then, as shown in FIG. 5, the lifter is lowered.

That is, since the pallet receiver 9 is provided with a mechanism that can be opened and closed, it is not necessary to raise the lifter to retract the pallet to the entry / exit position, thus simplifying the operation. It can also be used as an integrated system.

[0027]

As described above, according to the present invention, the carrier truck, which is the lifter truck, does not need a large independent site by moving the lower portion of the sheet metal material loading platform, and the sheet metal sheet is not required. A space-saving pallet transfer system that can streamline and reduce the installation space of the system as it can load materials and supply them to the sheet metal material loading platform or receive and carry out sheet metal materials from the sheet metal material loading platform can do.
