Description

[Detailed description of the invention] The present invention includes a shelf having multiple compartment storage spaces,
The present invention relates to a warehouse facility using pallets, which has a load transfer device that can travel along the shelves and transfer loads to and from the section storage space via pallets.

In such a warehouse facility that uses pallets, a cargo delivery device transfers cargo via pallets between a cargo handling area provided outside the end of the shelf and a compartment storage space, and the delivery and entry are performed by a cargo delivery device. Perform this work. Incidentally, there is no problem in a type in which loads are handled together with pallets outside the warehouse facility, but in a type in which only loads are handled outside the warehouse facility and pallets are not required, processing of empty pallets becomes a problem. In the past, empty pallets were stored in separate storage spaces. According to this, when entering the warehouse, empty pallets in the divided storage space must be moved to the handling area using a cargo handling device, and when leaving the warehouse, empty pallets at the handling area must be separated by the cargo handling device. Must be moved to storage space. Therefore, in addition to the expected loading/unloading cycle for transferring loads via pallets between the handling area and compartmentalized storage space, the loading/unloading device requires a cycle for transferring only empty pallets. As a result, the cycle time becomes longer and the operating efficiency of the cargo handling device decreases.

An object of the present invention is to provide a warehouse facility that utilizes pallets, which allows empty pallets to be kept within the facility, but which makes it unnecessary to operate a cargo delivery device for empty pallets.

In order to achieve the above object, the present invention provides a warehouse facility using pallets that includes a shelf having a plurality of compartment storage spaces, and a rack that is movable along the shelf and that transports goods via pallets between the compartment storage spaces. In a pallet-using warehouse facility having a cargo delivery device capable of delivering goods, a pallet stacking section is formed at the end of the shelf, and a loading/unloading section formed outside the end of the shelf and the pallet stacking section are connected to each other. A cart is provided that can travel between the pallets, the home position of this cart is formed between the pallet stacking section and the loading/unloading section, and the cargo is transferred together with the pallets to the cart at this home position by the cargo transfer device. is configured so that it can be delivered.

According to the present invention having such a configuration, the following effects can be expected. That is, at the time of unloading, the pallet along with the load is transferred from the delivery device to the trolley, and only the load is unloaded at the loading/unloading section, and the resulting empty pallet is carried by the trolley to the pallet stacking section and stored in that section. They can be stored by stacking them in a container. In addition, when warehousing, one empty pallet is passed onto the cart that has come to the pallet stacking section, the cart is moved to the loading/unloading section, the pallet is loaded, and then the cart is moved to the home position. By doing so, the cargo can be received together with the pallet by the delivery device. As a result, although the system keeps empty pallets within the facility, it is no longer necessary to operate the cargo delivery device only for empty pallets, and the cycle time of this cargo delivery device can be shortened to improve operating efficiency. I can do it.

An embodiment of the present invention will be described below based on the drawings. That is, 1 is a shelf arranged in parallel, and has a plurality of divided storage spaces 2 in the vertical direction and the horizontal direction. Reference numeral 3 denotes a passageway formed between the shelves 1, in which a cargo delivery device 4 that can run along the shelves 1 is provided. This cargo delivery device 4 has a pair of front and rear posts 5, and a lifting platform 6 that can be raised and lowered guided by these posts 5 has a fork 7 that can move in and out in the lateral direction.
will be provided. Therefore, the cargo delivery device 4 is operated by a combination of the running action along the shelf 1, the vertical movement of the lifting platform 6, and the lateral movement of the fork 7.
A pallet 9 on which loads 8 are placed can be delivered to and from the intended storage space 2. Said shelf 1
A pallet stacking section 10 is formed at the end of the pallet stacking section 10 with three compartment storage spaces 2 collapsed in the vertical direction. That is, the pallet stacking section 10 is a lifting frame 11.
A stop piece 12 that is horizontally swingable is provided at the lower square of the elevating frame 11. Said shelf 1
A loading/unloading section 13 is formed outside the end of the pallet stacking section 10, and a cart 14 that can run between the side of the loading/unloading section 13 and the lower part of the pallet stacking section 10 is provided. This trolley 14 is guided by rails 15 and can run on a fixed path, and a pallet receiving member 1 is mounted on the upper part.
6 is provided. And the pallet stacking section 10
A home position 17 of the cart 14 is formed between the loading/unloading section 13 and the loading/unloading section 13, and the cargo 8 together with the pallet 9 can be delivered to the cart 14 at the home position 17 by the cargo delivery device 4. .

Next, the action will be explained. First, stacked pallets 9 are brought in before operation. That is, the cart 14 is driven to the loading/unloading section 13, and the stacked pallets 9 are transferred from the loading/unloading section 13 onto the truck 14. Next, the cart 14 is moved to the pallet stacking section 10. Then, the lifting frame 11 is lowered, the locking piece 12 is swung inward to engage the lowest pallet 9, and then the lifting frame 11 is raised to lock the pallet 9.
The group can be lifted off the trolley 14 and stored. The cart 14 is then returned to the home position 17. When storing the cargo 8, the cart 14 is first driven to the pallet stacking section 10. Then, the lifting frame 11 is lowered and the pallet 9 group is transferred onto the cart 14. Next, the locking piece 12 is swung outward to release it, and after the elevating frame 11 is raised by one pallet, the locking piece 12 is swung inward. As a result, the locking piece 12 is engaged with the second pallet 9 from the bottom, and by raising the lifting frame 11,
With only the lowest pallet 9 remaining on the cart 14, all the remaining pallets can be lifted upwards. Thereafter, the cart 14 is moved to the loading/unloading section 13, and the pallet 9 is
Load 8 is placed on top. Next, the cart 14 is moved to the home position 17. The cargo 8 on the cart 14 is received together with the pallet 9 by the cargo delivery device 4, and delivered to the intended storage space 2 by the cargo delivery device 4, thereby completing the warehousing operation. When unloading the cargo 8, the cargo delivery device 4 first takes out the target cargo 8 together with the pallet 9 from the compartment storage space 2. The cargo delivery device 4 is then driven to a location corresponding to the home position 17, and the cargo 8 is delivered together with the pallet 9 to the cart 14 stopped at the home position 17. Next, the cart 14 is driven to the loading/unloading section 13 and only the cargo 8 is taken out to the loading/unloading section 13 side. Then, the cart 14 carrying the empty pallets 9 is driven to the pallet stacking section 10, and the pallets 9 are stacked and stored. after that,
The unloading operation is completed by returning the trolley 14 to the home position 17.

Note that when the pallet stacking section 10 is full due to continuous unloading work, several pallets 9
The other nine groups of pallets are transferred to the empty compartment storage space 2 by the cargo delivery device 4. In addition, the warehousing work is carried out continuously and the pallet stacking section 10
When there are only a few remaining pallets 9, the group of pallets 9 in the divided storage space 2 is moved to the pallet stacking section 10, contrary to the above. Therefore, the cargo delivery device 4 can be stopped not only at a location corresponding to the home position 17 but also at a location corresponding to the pallet stacking section 10.
