Description

[Detailed description of the invention] Among automatic warehouse systems, especially in automatic storage equipment for refrigerated warehouses, loading and unloading tables are often used for both loading and unloading in order to effectively utilize space and reduce building costs. When loading and unloading pallets using such a loading and unloading table, it is necessary to regulate the pallet position so that the pallets are stopped at a predetermined position. A loading/unloading platform guide device is required to enable loading and unloading.

If the guide device is fixed to the loading/unloading stand, if there is a large shift in the pallets during unloading, the pallets will be obstructed by the device and unloading will become impossible. Therefore, the guide device is supported by a cylinder mechanism, and if there is a shift of the pallet during unloading, the guide device is displaced so as not to interfere with the unloading of the pallet. However, the equipment cost is high. It had the disadvantage of being expensive.

The present invention has a simple structure that satisfies the functions required of a loading/unloading platform guide device. A pallet carrier supported by wheels on the shaped part can run along a groove, and a loading/unloading platform for loading/unloading pallets, on which pallets are placed on the upper surface, is perpendicular to the direction in which pallets travel when unloading. In order to position the pallet carried onto the loading/unloading table on the downstream side in the traveling direction of the pallet loaded onto the loading/unloading table from the direction, the pallet loading/unloading table is placed at the same width direction with respect to the pallet transport cart traveling direction. The gist is that a guide is provided with a weight attached below the center of rotation, which is attached to the side and rotates downstream in the pallet traveling direction and is knocked down by the pallet that is placed on the pallet traveling cart and moved when leaving the warehouse. It is something to do.

Next, an embodiment of the present invention will be explained with reference to the drawings. Reference numeral 1 is a loading/unloading platform provided in an automated warehouse, and a pallet transport vehicle running rail 2 is connected to the right side of the loading/unloading platform 1 in the figure. The pallet transport vehicle 3 is now running. When a pallet is put into storage, the pallet is carried onto the loading/unloading table 1 from the direction of arrow A in Fig. 1 and is transported in the direction of arrow B. When the pallet is taken out of stock, the pallet that has been transported in the direction of arrow C is After being lowered onto the loading/unloading stand 1, it is carried out in the direction of arrow D.

On the side of the loading/unloading table 1, there is a long and narrow guide 4.
is rotatably attached by a shaft 5.
A weight 6 is provided below the shaft 5 of the guide 4, and when the guide 4 is in its free state, the head 7 protrudes above the upper surface of the loading/unloading table 1.

In the above-mentioned apparatus, when a pallet is stored, the warehousing pallet 8 is carried onto the loading/unloading table 1 from the direction of arrow A in FIG. The position is regulated and placed on the loading/unloading table 1. Next, the pallet carrier 3 travels in a low position to below the warehousing pallet 8, stops, lifts up the warehousing pallet 8, and then carries it into the warehouse in the direction of arrow B.
Therefore, the pallets are stored in the automated warehouse storage shelves with their positions still regulated by the guides 4 and with zero deviation a.

When the pallets are unloaded, the unloaded pallets 9 are carried out in the direction of arrow C in most cases with a pallet shift a. The delivery pallet 9, which has been carried out by the pallet carrier 3 in a state where the pallet shift a has occurred, hits the head 7 of the guide 4.
Therefore, the guide 4 rotates counterclockwise in FIG. 2 about the shaft 5, and the head 7 retracts below the upper surface of the loading/unloading table 1. Pallet carrier 3
stops within the loading/unloading table 1, and after the loading/unloading pallet 9 is lowered onto the loading/unloading table 1 and is carried out in the direction of arrow D in FIG. Then, in FIG. 2, the pallet is rotated clockwise to restore the original state, and even if the pallet is shifted a, the delivery can be completed. If the lift amount of the pallet carrier 3 is large, the head 7 of the guide 4 will be pushed downward by the bottom surface of the unloading pallet 9 when the unloading pallet 9 is lowered onto the loading/unloading table 1. By providing a stopper or the like so that the guide 4 is inclined in the natural state as shown in FIG. 2, the head 7 is retracted below the upper surface of the loading/unloading table 1.

In addition to the illustrated embodiment, the present invention can also be used as a guide for a loading/unloading table using a conveyor device or a lifter device.

The present invention has a simple structure, low equipment cost, and has the effect of reducing failures.
