Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional automatic warehouse that can be installed on a very narrow site with a narrow frontage and a long depth.

[0002]

2. Description of the Related Art As described above, when constructing a three-dimensional automatic warehouse on a very long and narrow site, the loading and unloading of cargo is extremely reduced if one stacker crane is used in one traveling lane. In order to increase the loading / unloading amount of load, it is necessary to increase the number of stacker cranes traveling on one traveling lane.

[0003]

However, in order to avoid interference between the stacker cranes, it is necessary to limit the movement range of each stacker crane, and the loading / unloading table corresponding to each stacker crane is located in each area. It needs to be made independently. However, since the loading / unloading locations are distributed to a plurality of distant locations, the loading / unloading work cannot be performed at one location, and the loading / unloading work efficiency is reduced.

The present invention has been made in view of the above-mentioned problems, and a main object of the present invention is to equip one traveling lane with a plurality of stacker cranes while gathering the entrances and exits at one place to reduce the work efficiency. It is to provide a three-dimensional automatic warehouse that can be raised.

[0005]

The three-dimensional automatic warehouse according to the present invention includes: a) a rail bogie passage installed between a specified one warehouse entrance / exit and a predetermined location in the warehouse; A rack for a three-dimensional automatic warehouse provided with: b) one or more rails having a function of reciprocating on the rail bogie passage and transferring a load between a corresponding stacker crane and a warehouse entrance / exit table. And c) a plurality of stacker cranes installed on the same traveling lane capable of transferring loads to and from the corresponding rail trolley among the rail trolleys.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. Note that, in the description, a case where the three-dimensional automatic warehouse of the present invention is constructed on an elongated site on one side of a normal warehouse is taken as an example. As shown in FIG. 3, the three-dimensional automatic warehouse 10 of the present invention is constructed on an elongated site on one side of a normal warehouse 1.

[0007] As shown in FIG.
Is provided with one traveling lane 11 at the center thereof in the longitudinal direction of the warehouse 10. Although three stacker cranes 12, 13, and 14 are provided in the traveling lane 11, the first stacker crane 12 is provided at one end of the warehouse 10 so as not to interfere with each other. 15, the third stacker crane 14 reciprocates in the area C farthest from the entrance / exit port 15, and the second stacker crane 13 is sandwiched between the areas A and C. It reciprocates in the middle area B.

On both sides of the traveling lane 11, two rows of racks 20 are provided on one side. As shown in FIG. 2, the rack 20 is located at the bottom of the rack 20, and
The rack part located on the outermost side from the traveling lane 11
Each is a carriage passage 16. The one bogie passage (first bogie passage) 16A extends from the first rack 20a in the area A (the rack closest to the entrance 15 in the area A) to the first rack in the area B (in the area B). And the other bogie passage (second bogie passage) 16B.
Is installed from the first rack 20a in the area A to the first rack 20c in the area C (the rack closest to the entrance 15 in the area C). Also, rails 17 are respectively provided on the floor surfaces of the bogie passages 16A and 16B.
Is laid.

The first and second ports are located outside the entrance 15.
Of the truck passages 16A and 16B, respectively,
18A and a second entry / exit table 18B. Further, a third storage and retrieval table 18C is installed inside the first storage and retrieval table 18A, and a fourth storage and retrieval table 18D is installed inside the second storage and retrieval table 18B. Meanwhile, the first
The first bogie 19A disposed in the bogie passage 16A corresponds to the second stacker crane 13 in the area B, and the stacker crane 13 transfers the load. The second truck 19B disposed in the second truck passage 16B corresponds to the third stacker crane 14 in the area C, and the stacker crane 14 transfers a load. Further, the first carriage 19A has a function of transferring a load to and from the first loading / unloading table 18A located at the end of the first carriage passage 16A, for example, a roller conveyor or a chain conveyor. The second cart 19B has a function of transferring a load to and from the second loading / unloading table 18B located at the tip of the second cart passage 16B, for example, a roller conveyor or a chain conveyor.

Next, a description will be given of the loading / unloading operation of the load in the areas A, B and C. (A) Loading and Unloading Work of the Load in the Area A Loading and unloading work of the load in the area A is performed only by the first stacker crane 12. That is, when unloading a load from the rack 20 in the area A, the first stacker crane 12 raises the loading platform to a predetermined height, and then extends the fork on the loading platform to transfer the load in the rack 20 onto the loading platform. , And lowering the loading platform into place
Return to 5. Then, the fork on the loading platform is extended and the load is placed on the third loading / unloading platform 18C or the fourth loading / unloading platform 18D.

On the other hand, when loading the load on the third loading / unloading platform 18C or the fourth loading / unloading platform 18D, the first stacker crane 12 extends the fork on the loading platform to extend the third loading / unloading platform 18C. Alternatively, after the load on the fourth loading / unloading platform 18D is placed on the loading platform, the process proceeds to a predetermined rack 20 position in the area A, where the loading platform is raised to a predetermined height, and then the fork on the loading platform is lifted. And put the load in the rack 20. (B) Loading and Unloading Work of the Load in the Area B Loading and unloading work of the load in the area B is performed by the joint work of the second stacker crane 13 and the first bogie 19A. That is, when unloading the load from the rack 20 in the area B, the second stacker crane 13 raises the load to a predetermined height, and then extends the fork on the load to load the load in the rack 20 onto the load. , And lowers the carrier to the home position, and then returns to the area B in front of the first rack 20b. Therefore, the fork on the bed is extended, and the load is placed on the carriage 19A waiting at that position. The truck 19A loaded with the load advances to the first loading / unloading table 18A, where the roller conveyor or the chain conveyor is rotated to transfer the load onto the first loading / unloading table 18A.

When the load on the first loading / unloading table 18A is stored, the load on the first loading / unloading table 18A is loaded by the cart 19A by an arbitrary method (for example, a method of manual pushing by an operator).
Transfer to the top. At that time, the roller conveyor or the chain conveyor of the cart 19A is reversed. When the load is loaded on the cart 19A, the cart 19A is returned to the standby position, that is, the front of the first rack 20b in the area B. The second stacker crane 13 waiting at that position extends the fork on the carrier and places the load on the trolley 19A on the carrier, and then proceeds to the position of the predetermined rack 20 in the area B, where After the carrier is raised to a predetermined height, the fork is extended and the cargo is stored in the rack 20. (C) Loading and Unloading Work of the Load in the Area C Loading and unloading work of the load in the area C is performed by the joint work of the third stacker crane 14 and the second bogie 19B. That is, when unloading a load from the rack 20 in the area C, the third stacker crane 14 raises the load to a predetermined height, and then extends the fork on the load to load the load in the rack 20 onto the load. And returns to the area C in front of the first rack 20c after lowering the carrier to the home position. Therefore, the fork is extended and the load is placed on the carriage 19B waiting at that position. Dolly 19 with load
B advances to the second loading / unloading table 18B, where it rotates the roller conveyor or the chain conveyor to load the second cargo.
To the loading / unloading table 18B.

When loading the load on the second loading / unloading table 18B, the load on the second loading / unloading table 18B can be transferred to the cart 19B by an arbitrary method (for example, a method of manual pushing by an operator).
Transfer to the top. At this time, the roller conveyor or the chain conveyor of the cart 19B is reversed. When the load is loaded on the cart 19B, the cart 19B is returned to the standby position, that is, the front of the first rack 20c in the area C. The third stacker crane 14 waiting at that position extends the fork on the carrier and places the load on the trolley 19B on the carrier, and then proceeds to the position of the predetermined rack 20 in the area C. After the carrier is raised to a predetermined height, the fork is extended and the cargo is stored in the rack 20.

Of course, as described above, by installing a plurality of warehouses adjacent to each other, it is possible to realize a warehouse having a plurality of crane traveling lanes and a plurality of cranes in one lane.

[0015]

As described above, according to the present invention, although a plurality of stacker cranes are provided on one traveling lane of a very long three-dimensional automatic warehouse, the stacker cranes and the trolleys are used. By the linked play, the warehouse length is standard, equipped with one stacker crane in each lane, and the entrance / exit capacity is equal to or greater than that of a normal three-dimensional automatic warehouse with the same total number. Can be demonstrated.

Further, since a plurality of stacker cranes are provided in the same traveling lane, there is an advantage that even if one of the cranes fails, the remaining cranes can continue the loading / unloading operation.
