Abstract

PURPOSE:To miniaturize and simplify the warehouse and enhance the shipping performance and efficiency of the same multistoried piling automatic warehouse for containers or the like, by providing a warehousing conveyor on the floor of an one-story warehouse, and by juxtaposing forklift devices, and also by arranging overhead traveling cranes with a hoisting tool crosswise. CONSTITUTION:A crane girder 4 is provided on the ceiling of a warehouse, and automatic overhead traveling cranes 5 are provided on the girder 4. To the crane 5, an automatic hoisting tool 7 is hung down. On the other hand, on the floor of the warehouse, a warehousing conveyor 2 is arranged so as to be perpendicular to the overhead traveling cranes 5, and forklift devices 3 are juxtaposed. And, the goods (a) warehoused by the warehousing conveyor 2 are temporarily placed on the forklift device 3, and then they are stored by the overhead traveling cranes 5. Thus, the warehousing area can be reduced, and the floor passage can be effectively utilized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic warehouse equipped with a loading/unloading mechanism for transferring, stacking, and temporarily storing rigid cargo such as containers.

[Conventional technology]

A conventional example of a three-dimensional warehouse will be explained with reference to FIGS. 6 and 7. A rack structure 101 having a large number of rack parts arranged in parallel and in multiple stages is erected in parallel via a floor path 102,
A stacker crane 104 is disposed on a running rail 103 provided at the end track 102, and a running rail 101 of a transport vehicle 105 is provided next to the rack structure 101 as an entry/exit facility. 101 and 101, and by lifting and lowering the lifting platform 104a of the stacker crane 104, the cargo a is delivered to each rack section of each rack structure, and the transport cart 105 is moved inside the multi-story warehouse 107. The transfer, temporary storage, or handover of cargo to and from the warehouse is performed within the multi-level warehouse 107. Further, the stacker crane 104 is connected to the rack structure 10.
1 and the space above it.

[Problem to be solved by the invention]

The above-mentioned conventional technology has the following problems.

(1) For the traveling movement of the stacker crane, the space between the ends of the rack structures and above them is occupied. (2
)Stacker crane and ground transportation means (transportation trolley, etc.)
Since the transfer (transfer, temporary storage) of cargo between warehouses is carried out within the warehouse, a large transfer area is required next to the rack structure.

(3) The distance that cargo is transported by the stacker crane becomes longer, resulting in poor efficiency.

(4) A stacker crane requires a high side column that corresponds to the height of the rack structure, and as the rack structure becomes taller, it becomes larger and heavier, resulting in higher costs. (5
) An extra space is required between each layer of the rack structure constituting the rack section and the load, which increases the size and weight of the rack structure itself and increases cost.

The present invention was developed to address the above-mentioned problems, and by eliminating the rack structure and effectively utilizing the end paths between items, the present invention achieves miniaturization and simplification of the mechanism, and also reduces the burden on people and people. The purpose is to provide a multi-level automated warehouse with improved delivery performance and efficiency.

[Means to solve the problem]

As shown in FIGS. 1 to 3, a crane girder 4 is provided on the ceiling of a warehouse, and an automatic overhead traveling crane 5 that travels on a traveling rail laid on the crane girder 4 is provided. An automatic hoist 7 having a device for attaching and detaching cargo to and from cargo is suspended from an overhead traveling crane 5. An incoming conveyor 2 that is perpendicular to the automatic overhead crane 5 and a fork lifter device 3 attached to the conveyor 2 are installed to directly transport cargo from the floor below the automatic overhead crane 5's running path. Construct a temporary storage floor that is stacked in multiple tiers.

[Effect]

The goods are carried into the warehouse by the receiving container (A), and the forks and
Place the cargo on the lifter device.

An automatic overhead crane travels above the warehouse, and lifting equipment is raised and lowered via hoisting ropes. An attachment/detachment device attached to the hoisting device grasps the cargo on the fork lifter device, lifts it up, moves it, and stacks it one after another at a predetermined location.

〔Example〕

Embodiments of the present invention will be described with reference to FIGS. 1 to 5. FIG.

Baggage placed on the warehousing conveyor 2 from outside the multi-level automated warehouse 1 is transported into the warehouse and temporarily placed on a predetermined fork lifter device 3, which is placed on one or more pairs of crane girders. An overhead traveling crane 5 traveling above -4.4 moves on its own and stops directly above a predetermined load a of the fork lifter device 3, and several hoisting ropes 6.6 are attached to the crane 5. The baggage a is grabbed by a detachable device 10 attached to a hanging tool 7 that can be lifted up and down through the
The lifting device 7 is raised to a height where it can be transported, the overhead traveling crane 5 is used to transport the cargo to a predetermined position, the cargo a is lowered to a predetermined storage location, the cargo a is detached from the attaching/detaching device 10, and temporarily stored. Complete the inventory work.

The unloading operation is completed by grabbing the cargo a, temporarily placing it in the handling area 8 in the automated warehouse 1, and carrying it out of the warehouse using a forklift or other transportation means, in the same manner as described above.

Next, the attachment/detachment [110] will be explained with reference to FIGS. 4 and 5.

A gear motor 11 with a clutch supported by the frame of the hanging tool 7 (not shown) drives a pinion 14 and a rack 1 through a miter gear 12 and a universal joint 13.
The chuck 1 is fixed to the tip of the rack 15 by driving the chuck 5.
6 approaches the baggage a and stops automatically, and then inflates the inflatable seal 17 fitted into the chuck 16 with air pressure (arrow in the figure) and presses it onto the baggage a.
:Can be grasped.

Each of the above-mentioned operations is performed continuously by an appropriate remote control mechanism (not shown), and almost the entire floor surface is used as a storage area for stacking luggage in multiple stages.

Part of the floor has conveyor #2 and fork lifter #3
This is the place for receiving and receiving the hanging equipment 7, and the overhead traveling crane 5.
With the attachment/detachment device 10 attached to the hanger 7, people can be quickly and effectively taken out of the warehouse.

(According to the present invention, the cargo a can be stacked in multiple stages without installing a rack structure, and the space in the automated warehouse 1 can be used effectively, so that the cargo storage effect can be enhanced.

〔Effect of the invention〕

The multi-level automatic warehouse according to the present invention includes a warehousing conveyor installed on the floor of a one-story warehouse, an overhead traveling crane installed perpendicular to the warehousing conveyor, and a cargo loading/unloading device suspended from the overhead traveling crane. The fork lifter device is provided along the storage conveyor and has the following effects.

(1) Almost the entire floor surface can be used as a storage space, so the storage area can be small.

(2) Buildings can be constructed economically by eliminating rack structures.

(3) It can be used for many purposes by changing the hanging tool to suit the shape of the cargo.
