Description

TECHNICAL FIELD The present invention relates to a cold storage container transportation / storage device for transporting and storing a large number of small cold storage containers for home delivery in a cold storage state. is there.

[Conventional technology]

Along with the progress of home delivery business, home delivery of cold-required products, which are roughly classified into frozen, chilled, and cool, has come into widespread use. As a method of keeping cold during the delivery of those products, a method of storing the products together with dry ice, a cold storage agent, ice, etc. in a foamed plastic container is generally used.
In this method, there is a problem that the coolable time is short, and when a dedicated cold storage vehicle is used, there is a problem that the equipment is expensive, general luggage cannot be mixed, and there is a lot of wasted space. Therefore, the present inventors have developed a new individual cooling system for each container (Japanese Patent Application Nos. 60-213084 and 61-49986).

However, in the case of home delivery, it generally goes through the route such as the agent at the end, the center (medium-sized collection point), the base (large-sized collection point), etc., but it is expected that the number of cold storage containers will increase more and more in the future. Considering it, mass transportation between bases and container storage system at bases will become a big problem,
Conventionally, no system has been proposed to meet the demand.

[Problems to be Solved by the Invention]

Therefore, the present invention cools each container in a predetermined temperature zone during mass transportation between bases or in a place where a large number of containers like a base need to be gathered and temporarily stored. An object of the present invention is to provide a cold-storage container transportation / storage device that can transport and store a large number of materials in an orderly manner.

[Means for Solving the Problems]

The present invention comprises a cooling device for supplying a cooling gas and a storage device docked to the cooling device, and the storage device is pushed by a cooler for supplying the cooling gas protruding from the front surface of the cooling device. A means for opening an insertion port that allows the cooler to enter therethrough, or a cooling device for supplying cooling gas and a storage box docked to the cooling device. The problem has been solved by providing several kinds of nozzles having different ejection amounts for ejecting cooling gas to the entire chamber, and a cooling gas injection needle inserted into each container accommodated in the container.

In the storage, a plurality of shelves are formed by inserting a plurality of shelves in an airtight state. In the first means (invention), the storage box has a safety switch operation button for turning on a safety switch of the cooling device (which controls ejection of cooling gas from the cooler) and a select switch (cooling in each cooler). A selector switch actuating button for selecting and controlling the temperature) may be installed.

[Action]

Pull out the shelves of the storage and place multiple containers. At that time, a container having the same cold insulation temperature should be placed on one shelf. When all the containers are in the same cooling temperature range, a single operation of turning the main switch on and off may be performed after docking the storage and the cooling device to select the temperature. Also, when placing a container with a different cooling temperature range for each partition room, after selecting and operating the select switch operation button, dock the cooling device and storage, or operate the select switch after docking to cool. The instrument enters the storage through the insertion port, and within the selected temperature range,
Cooling is performed for each partition room.

Further, in the second means (invention), the nozzle is selectively operated according to the cold insulation temperature, and in the case of a frozen product, the nozzle is used to cool the container from the outside, and the gas injection needle is pierced into the container to Cool directly.

During transportation, it is possible to extend the cold insulation time by rapidly cooling the inside of the storage to bring it into a supercooled state. Even in such a case, the product precooled and stored in the container is protected by the container made of the heat insulating material and is not overcooled. Cooling with liquefied nitrogen is optimal for this quenching work,
The work time can be greatly reduced.
