JPS583900B2 - Pallets for automated warehouses - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in pallets for automated warehouses, and more particularly to a pallet in which loads can be separated from the pallet by cooperation with an intermediate article conveyance device.

An automated warehouse consists of racks that store cargo, cranes that move and move up and down the racks to load and unload cargo into and out of the racks.
It consists of a control device that controls this crane.

To store loads in racks, the loads are not directly stored in the racks, but are handled by a forklift installed on a crane, so the loads are usually placed on a loading platform called a pallet. The products are stored in the rack in the same state as they are placed, and then taken out from the rack and transferred by crane to an intermediate device for transporting goods (hereinafter referred to as intermediate device) to complete unloading.

Once the cargo has been transferred to the intermediate device and has been unloaded, it is further transported to the destination location, but conventional intermediate devices do not have a function to separate the cargo from the pallet, so the cargo is always placed on the pallet and is transported by a forklift, etc. This was a major drawback of automated warehouses, as it usually required manual labor to separate the materials.

Therefore, the applicant of the present application has invented and filed an application for an article conveyance intermediate device equipped with a push-up mechanism for separating loads and pallets. Aim to get a pallet.

To briefly explain the above intermediate device, the intermediate device has a loading platform on which the cargo that has been discharged is placed together with the pallet.
At the bottom of this loading platform, there is a mechanism that moves up and down using hydraulic pressure, separates only the load from the pallet, and pushes it up from the loading platform to a desired height.

Therefore, pallets used for such purposes differ from ordinary pallets having a flat plate shape, and have a plurality of holes through which a load-lifting mechanism can pass.

The pallet of the present invention will be explained below with reference to the drawings.

FIG. 1 is a plan view showing a pallet P according to an embodiment of the present invention, and FIG. 2 is a side view thereof.

In the figure, 1 is a frame body, which has a reinforcing beam 2 in the middle, and holes 3, 4, 5, 6, 7 for passing the lifting parts 21 to 28 of the load-lifting mechanism 20 shown by dashed lines. , 8 are left in place, and flat plates 9 and 10 are stretched over the frame 1, or they are arranged in a lattice shape (not shown) so that the upper surface forms one plane, so that a load can be placed thereon.

11, 12, 13, and 14 are legs for forming a fork insertion gap of a forklift.

In FIG. 2, reference numeral 30 indicated by a chain line indicates a loading platform on which a pallet P of the intermediate device is placed, and 32 and 33 indicated by a chain line 32 and 33 indicate loads placed on the pallet P.

Although this embodiment shows a case in which a maximum of four loads can be separated independently from the pallet P, it goes without saying that the number of loads can be arbitrarily determined.

The present invention has been described above, but by using the pallet of the present invention in combination with an intermediate article conveying device having a load-lifting mechanism, the load that has been unloaded from the rack can be separated from the pallet and only the load can be transported. can do.
