[0005]

[Problems to be Solved by the Invention]
It is unavoidable to use normally operated unloading equipment by a person specializing in the work.After that, place the pallet on the platform or transport vehicle or transfer the pallet to the storage location. None, it is necessary to use an unknown number of forklift trucks and conveyors to hold the pallets for subsequent transfer and deposit on the storage location. The pallets are placed in storage and protected during standby.

[0006] These unloading operations currently also require the use of a considerable amount of labor on self-driven transport trucks for the transfer and subsequent placement, stacking and storage of pallets. Obviously, the impediments have been hampered due to the essential requirements.

A known solution to the existing problem of the above is to equip the gantry crane with auxiliary equipment, machinery or equipment, by means of which the transport platforms installed in different types of vehicles, Direct unloading of pallets to transfer the pallets to their destination and, by using a tractor, to a storage location or storage room that protects the pallets during appropriate transfer waits. To provide convenience.

However, the existence of a device whose characteristics are compatible with the above is not known so far.

[0009]

OBJECTS OF THE INVENTION To provide an obvious solution to the above problems, the device of the present invention comprises a multi-directional conveyor for manipulating a plurality of pallets, which itself comprises a group of pallets on an auxiliary platform. It is constructed so that it can be loaded in two stages, whereby the pallets are transferred to a transfer vehicle so that the products on the pallets are distributed or carried to a storage location.

[0010]

In particular, the device for handling multiple sets of pallets, which is the subject of the present invention, is designed on the rear structure of a conventional gantry crane and is equipped with a standby platform on which , Pallets are collected, grouped, then moved to a transfer vehicle, distributed, or transported to a storage point, said pallets being grouped into 12 sets or similar numbers.

In order to remove the pallets from the cage, place them on a waiting platform, and finally load them onto a transfer vehicle, the gantry crane described above follows a structure suspended from the actual gantry. It is equipped with a slidable control unit that can be operated by a robot.

This conveyor machine is installed on two bridge girders suspended from a truck that runs along two track girders that form part of the actual structure of a gantry crane.

As described above, from those bridge girders incorporated into the structure of the gantry crane, forks performing a vertical transfer are suspended and, as a result of this transfer,
Picking up one pallet from the unloading point of the trolley,
Distribute it anywhere on the standby platform or on the platform of the transport vehicle located on the ground.

Of course, loading vehicle placement must be performed at the same time as the initial work of the unloading / loading cycle. The device is equipped with a motor and is equipped with a hydraulic device for obtaining approaching, ascending and descending motions of the double fork with respect to each pallet, thereby enabling transfer.
It is designed to achieve transverse and longitudinal transport of the device.

The entire mechanical maneuver is controlled by the P.S.C. so that the operating procedure can be repeated with a minimum number of personnel and auxiliaries. L. C. Controlled by. However, it goes without saying that the vehicles to be loaded are arranged in advance at specific points.

As a matter of course, the multi-directional conveyor can be manually operated and sequentially executes all the sets of work.
You may perform some of these tasks manually.

The above-mentioned conveyor can be made to be convenient for carrying out the procedure of loading / unloading from the ship to the transfer vehicle and from the transfer vehicle to the ship, in other words, in reverse. It is necessary to point out what can be done.

To supplement the above description and to enable a fuller understanding of the features of the present invention, this specification presents the following four plans and illustrated methods. .
