JP3752415B2 - Double storage type automatic warehouse - Google Patents

Description

[0001]
[Prior art]
In order to increase the number of loads that can be accommodated in a multi-layer stacking shelf, a so-called double storage type in which a plurality of shelves, that is, a front shelf and a rear shelf are provided in the direction of movement of the transfer device for each shelf row. A shelf structure has been used. In the case of a shelf structure using this double storage system, when a load stored in the rear shelf is output by a stacker crane, the load stored in the front shelf is moved to another shelf and then stored in the rear shelf. The cargo that was being shipped was being taken out. Therefore, in the case of a double storage type shelf structure, it is necessary to always provide a replacement shelf for storing the load stored in the front shelf, so that the total number of shelves cannot be used for storing loads. was there.
[0002]
Hereinafter, a shelf structure in a conventional automatic warehouse will be described with reference to FIGS.
[0003]
6-7, 1a is the loading / unloading station of the load provided in the edge part of each shelf row 9 between shelf pillars 5a and 5b, and has the empty space 15 on both sides of the station part 1a.
[0004]
4 is a shelf supported by beams and shelf columns 5a and 5b, 9 is a shelf row, 10 is a front shelf provided in each shelf row, 11 is a rear shelf, 12 is a transfer device passage, and 13 is a transfer device. , 14 is a pallet receiver.
[0005]
Thus, in the conventional automatic warehouse, since the shelf column 5b is provided on the transfer device passage 12 side of the station 1, the station 1 must be provided between the shelf columns 5a and 5b. There were dead spaces 15 on both sides.
[0006]
[Problems to be solved by the invention]
As described above, in the case of the conventional double storage type shelf structure, when the cargo stored in the rear shelf is discharged, the evacuation shelf for evacuating the cargo stored in the front shelf is placed in the shelf row. The shelves for evacuation are not always used for storing loads, which causes a reduction in storage efficiency of the shelves. Therefore, the present invention solves the above-described conventional problems by providing a shelving shelves in a station portion that is not conventionally used as a dead space in a double storage type shelf. And as explained as a conventional device, since the shelf column supporting the hanging shelf is provided on the passage side of the transfer device of the conventional station unit, the station unit is provided in the middle part between the shelf columns, and therefore the station unit There was a dead space on both sides. In order to solve the above problems, the present invention aims to improve shelf storage efficiency by changing the installation of shelf columns and using the dead space of the station unit as a shelving shelf.
[0007]
[Means for Solving the Problems]
The present invention solves the above-mentioned problem, and in a double storage type automatic warehouse, a loading / unloading station is provided on the transfer device passage side at the end of each shelf row, and a retreat shelf retreat shelf is provided at the rear thereof. While being provided, the shelf column on the transfer device passage side is erected on the hanging shelf.
[0008]
Since the present invention has the above-described configuration, the empty space on both sides of the station portion that has not been used at all as a space for a conventional warehouse can be used as a shelving shelf. It is possible to provide an automatic warehouse that can be repaired at low cost even if it has a conventional shelf structure.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
According to a first aspect of the present invention, the communication direction being defined by erected struts from the floor, a shelf which is divided into front and rear with respect to the passage of the transfer device by the shelf member provided between posts In a double storage type automatic warehouse equipped with a loading / unloading station at the end of the shelf row, the shelf column on the transfer device passage side of the loading / unloading station stands on a suspension shelf provided above the loading / unloading station. It is characterized in that the loading / unloading station is located on the passage side of the transfer device, and the evacuation shelf is provided at the rear of the loading / unloading station. Can be used as shelving shelves, so that all shelves can be used to store loads, and even when the conventional shelf structure is modified to the above-described shelf structure, Renovation at cost Rukoto has an action that can.
[0010]
The invention according to claim 2 is a shelf in which the direction of communication is partitioned by columns that are erected from the floor surface, and shelves that are divided forward and backward with respect to the passage for transfer placement by shelves provided between the columns, In a double storage type automatic warehouse equipped with a loading / unloading station at the end of the shelf row, a shelf column on the transfer device passage side of the loading / unloading station is erected on the transfer device passage, and the loading / unloading station is The retraction shelf is erected on a suspension shelf provided at the rear of the loading / unloading station on the passage side of the transfer device, and has the same effect as that of the first aspect of the invention.
[0012]
Embodiments of the present invention will be described below with reference to the drawings.
(Embodiment 1)
1-4, 1 is a loading / unloading station provided at the end of each shelf row 9, and the station 1 is provided along the passage side 12 of the transfer device, An evacuation shelf 2 for evacuating the load is provided. Reference numeral 3 denotes a beam for supporting a hanging shelf that protrudes from the end of each shelf row toward the handling portion. A hanging shelf 4 is attached on the beam 3. 5a is a shelf column provided on the retreat shelf 2 side, and 5b is a shelf column provided on the station 1 side, that is, on the passage 12 side of the transfer device. ing. 6 is a building pillar, 7 is a roof provided in the handling section, 8 is a handling section, 9 is a shelf row, 10 is a front shelf provided for each shelf, 11 is a rear shelf, 12 is a transfer device passage, Reference numeral 13 denotes a transfer device, reference numeral 14 a denotes a pallet receiver for the evacuation shelf 2, and reference numeral 14 b denotes a pallet receiver for the station 1.
