Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultra-low temperature three-dimensional automated warehouse.

0002

[Prior Art] Conventional ultra-low temperature multi-storey warehouses generally consist of a main warehouse whose temperature is controlled in an ultra-low temperature atmosphere and a front room connected to this main warehouse. Warehouse shelves are provided.

0003

[Problem to be solved] In conventional cold storage warehouses that are not ultra-low temperature, automated machines such as stacker cranes are installed inside the main cold storage warehouse, but in ultra-low temperature cold storage warehouses,
The temperature of the main cold storage warehouse is extremely low, below -40℃, so it is impossible to install automated machinery inside the main cold storage warehouse because the low temperature resistance of electrical equipment is limited to -40℃. It was possible, but mechanization was not possible.

[0004]Also, even if a cooling system is installed in a space that is a rack-type warehouse shelf surrounded by heat-insulating walls and heat-insulating doors, and the space is to be used as a main warehouse for cold storage, conventional heat-insulating doors are opened and closed electrically. As a result, the construction cost would be enormous, making it unfeasible.

[0005] An object of the present invention is to provide an ultra-low temperature three-dimensional automatic warehouse that can solve the above-mentioned problems.

[0006]

[Means for Solving the Problems] The ultra-low temperature three-dimensional automatic warehouse of the present invention is a rack-type three-dimensional warehouse consisting of a plurality of shelves inside a cold storage warehouse body surrounded by heat insulating walls, and a removable heat insulating door on one side. The other side is surrounded by a heat insulating wall, and a refrigerated main warehouse equipped with a cooling device is provided.

[0007]The heat-insulated door of the refrigerated main warehouse is opened and closed by a door opening/closing mechanism provided on an automated machine such as a stacker crane.

[0008]

[Function] It has a double structure with a main refrigerated warehouse inside the main refrigerated warehouse, and the temperature inside the main refrigerated warehouse is maintained below -40℃ by the cooling device. For example, the temperature is 20 to 30 degrees Celsius higher than the temperature within the range, and maintained at a temperature higher than the low temperature resistance performance limit temperature of electrical products. This makes it possible to use automated machinery such as stacker cranes within the refrigerated warehouse, making it possible to realize an ultra-low temperature three-dimensional automated warehouse.

[0009] Furthermore, by having a configuration in which the heat-insulated door of the refrigerated main warehouse is opened and closed by a door opening/closing mechanism provided on an automated machine such as a stacker crane, construction costs can be significantly reduced compared to the case of using a conventional electric door. I can do it.

Furthermore, since the temperature inside the divided refrigerated main compartment can be adjusted to the required refrigeration temperature, the cooling equipment capacity can be greatly increased compared to the conventional case where the entire main compartment except the front room is kept at an ultra-low temperature. can be made smaller.

[0011]

In this way, the luggage is stored in a predetermined rack shelf of the refrigerated bookshelf 2.

[0020] The cargo stored in the refrigerated book storage 2 is carried out by the reverse procedure to the above.

[0021] In the above embodiment, the refrigerated main storage 2 is provided inside the refrigerated warehouse main body 1 to have a double structure, but the insulating wall 5 of the refrigerated main storage 2 is shared with the insulating wall of the refrigerated warehouse main body. You can do it like this.

[0022] In the above embodiment, the cooling device is installed at the top of each refrigerated main cabinet, but the installation position is not limited to the upper part.
This may be covered by one cooling device. Further, a cooling device may be provided outside the refrigerated main cabinet, and, for example, cold air may be circulated within the refrigerated main cabinet.

Next, another example of opening and closing the heat insulating door will be explained with reference to FIG. Wheels 14a are provided on the top and bottom of the heat-insulating door 14, and a hook 14b is provided on the front surface. On the other hand, refrigerated book storage 2
A guide rail 16 is provided in front of the. This guide rail 16 is composed of an elevating guide part 16a and a closing guide part 16b that slopes downward from this guide part toward the refrigerated main storage 2 in accordance with the distance between the wheels.

[0024] The heat-insulating door 14 normally has a closing guide portion 16 whose wheels 14a are inclined downward, as shown by the two-dot chain line.
b and is automatically closed by the weight of the door. Then, to open the door, the door opening/closing mechanism 11 provided in the automated machine 10 raises the door 14 along the lifting guide part 16a via the hook 14b and locks it to the locking mechanism 17. In this way, the pallet 7 is loaded and unloaded by the fork 12 provided on the automated machine 10.

In the above embodiment, the opened door is locked by the locking mechanism 17, but as shown in FIG. A portion 16c may be further provided, and the lower wheel of the opened door may be engaged with and locked.
