Abstract

PURPOSE:To dispense with a space for keeping bulky pallets in a stacked state by feeding a pallet becoming empty at an unloading position in a pallet melting apparatus and reproducing the molding material in the melting apparatus into the pallet by a pallet molding apparatus. CONSTITUTION:When a delivery command is issued, a crane 3 takes out a load 5 from the predetermined position of a storing shelf 3 along with a pallet 12 and said load 5 is fed to an unloading position 9 by a delivery conveyor 10. When the load 5 is fed out from the pallet 12 at the unleading position 9, the used pallet 12 becoming empty is sent in a pallet melting apparatus 14 by a conveyor 19. The pallet 12 fed in the apparatus 14 is cut or ground into small pieces to be melted by a melting apparatus 16. Subsequently, the molten material is molded into the pallet and, after the pallet is kept, a new plastic material is replenished if necessary to be subjected to reproduction.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pallet recycling system used in warehouse facilities and the like that transport and store cargo using plastic pallets.

(Prior Art and its Problems) As the number of products handled increases and their shapes and sizes become more diverse, a wide variety of special pallets are required to accommodate each product. These various specialized pallets must be stacked and stored until they are used for loading, so a very large space is required to store the pallets, and when that space cannot be secured indoors, they are left exposed outdoors. This resulted in a shortened service life of the pallet itself. Furthermore, it is necessary to search for a pallet that matches the product being handled among a large number of stored pallets, and it is also necessary to use a forklift to stack stacked pallets after they have been taken apart, making it difficult to handle the pallets themselves. It required a lot of effort and time.

(Means for Solving the Problems) In order to solve the conventional problems as described above, the present invention has the following features:
A conveyor for conveying pallets sent out from the pallet forming device to a loading position, and a conveyor for conveying empty pallets at the unloading position to pallet melting equipment are provided, and the molding obtained in the pallet melting equipment is provided. A pallet recycling system configured to feed material into the pallet forming device is proposed.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

(1) is an automated warehouse, in which cargoes (5) loaded on pallets are transferred from storage shelves (2), lanes for loading and unloading (3), and loading position (4) to the crane (3). The receiving conveyor (7) transports the receiving goods to the delivery position (6).
, and the unloading cargo receiver of the crane (3) is at the delivery position (8
This is a conventionally well-known device that includes a delivery conveyor (10) for transporting the cargo (5) delivered to the unloading position (9).

Reference numeral (11) denotes a pallet forming device, and is provided with a conveyor (13) for conveying pallets (12) sent out from the pallet forming device (11) to the loading position (4). (14) is pallet melting equipment, including a pallet cutting device (15), a melting device (16) for melting cut plastic pieces, and a pellet forming device (17) for forming pellets from melted plastic ink.
), and a pellet tank (18), and from this pellet tank (18) the pallet forming device (11
) is automatically supplied with Pelle 7). (19) is a conveyor that feeds the used pallet (12) that has become empty at the unloading position (8) to the pallet cutting device (15). (20) is a storage shelf for pallet molding molds;
The necessary mold is selected and the pallet molding device (11)
is set to

Since the type (shape and size) of the cargo (5) to be stored in the automated warehouse (1) is known in advance, the cargo (5) in question is loaded before the cargo (5) in question is carried into the loading position (4). Based on the data, a special pallet (12) is formed by a pallet forming device (11), and the formed pallet (12) is conveyed to a loading position (4) by a conveyor (13).

However, at the loading position (4), the pallet (12
) and load the specified cargo (5) onto the receiving conveyor (7).
Therefore, the receiving goods for warehousing in the automated warehouse (1) are transferred to the delivery position (6).
Transport to. The crane (3) is at the delivery position (
The cargo (5) of step 6) is automatically stored in the predetermined position of the storage shelf (2) together with the pallet (12).

When there is a command to take out the warehouse, the crane (3) moves to the storage shelf (3).
The cargo (5) is taken out along with the pallet h (12) from a predetermined position, and the unloading cargo receiver is delivered to the delivery position (8), so the front (5) is transported to the unloading position (9) by the unloading conveyor (10). transport. After unloading the load (5) from above the pallet (12) at the unloading position (9), the empty used pallet (12) is transferred to the pallet melting equipment (14) by the conveyor (19). Send it in.

The pallet sent into the barreme (14)
12) is cut or crushed into small pieces by a cutting device (15) and then melted by a melting device (16). Then, it is molded into pellets by a pallet molding device (17),
Stored in pellet tank (18). Note that when molding pellets with the pellet molding device (17), new plastic material can be replenished as necessary.

However, the pallet forming device (11) uses the pellets in the pellet tank (18) to form a pallet (12).
) to form.

Note that the configuration of the pallet melting equipment (14) is not limited to that of the above embodiment. For example, the pallet cutting device (15) may be omitted and the pallet (12) may be directly heated and melted, or the pellet forming device (17) and pellet tank (18) may be omitted and the pellets obtained by the melting device (16) may be used. It is also possible to feed the liquid plastic directly to the pallet forming device (11).

(Operations and Effects of the Invention) The present invention can be carried out as described above, and according to the pallet recycling system of the present invention, used pallets are melted in the melting equipment, so they are bulky and expensive. There is no need for storage space for stacking pallets and storing them, and the efficiency of floor space utilization in warehouse facilities can be greatly increased. Of course, there is no fear that the pallets will deteriorate during storage, which is the case when pallets are stacked in the open. Furthermore, the effort and time required to stack and un-stack pallets using a forklift becomes unnecessary.

In addition, pallets that match the shape and size of the cargo to be handled are formed each time using pallet forming equipment.
There is no need for the trouble of searching for a suitable pallet among a large number of storage pallets, and since a pallet suitable for the load can be used, highly safe transportation and storage is possible.
