Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an article cooling and conveying system for conveying a cooled article from one place to another place by means of a transport vehicle while cooling the article.

[Conventional technology]

Generally, a transport vehicle equipped with a refrigerator or a refrigerator (hereinafter referred to as a refrigerated vehicle) is used to transport refrigerated articles. The refrigerated goods in the frozen warehouse are then loaded onto a refrigerated vehicle and transported to a destination (ie, a station).

At the destination, the refrigerated goods are unloaded from the refrigerated vehicle and stored in a refrigerated warehouse. In addition, in order to transfer the refrigerated goods stored in this frozen warehouse to another location, they must be loaded onto a refrigerated truck and transported again.

In addition, refrigerated goods transported by refrigerated trucks to a relay location (i.e., a station) are unloaded here, sorted, etc., and then transported in separate refrigerated trucks depending on the sorting.

[Problem that the invention seeks to solve]

In either case, the refrigerated articles unloaded from the refrigerated vehicle to the station must also be immediately stored in the refrigerated warehouse. That is, each station must be equipped with a refrigerated warehouse. In other words, a location that does not have a cold store cannot serve as the above-mentioned station in this type of system. For this reason.

There is a problem in that the equipment cost at each station increases.

In particular, goods are collected from households and businesses in the region to stations such as stores and centers.

To handle refrigerated goods in an individual goods delivery system that sorts and transports the goods by region, and then delivers them to each home, office, etc.

There is also the problem that all stations must have their own cold storage.

Therefore, a technical object of the present invention is to provide an article cooling and conveying system that can handle chilled articles without having to provide a refrigerated warehouse at each station.

[Means for solving problems]

According to the present invention, there is provided an insulated container in which cooling goods can be stored at a station and which can be loaded and unloaded onto the transport vehicle, a first cooling device capable of cooling the inside of the container at the stage, and a first cooling device on the transport vehicle. and a second cooling device capable of cooling the inside of the container.

is connected to the heat insulating container 8 shown in FIG. 3, and is capable of cooling the inside of the heat insulating container 8. In other words, the inside of the insulated container 8 is cooled by the cold air unit 13 when it is loaded onto the horizontal carriage 11 .

On the other hand, the heat insulating container 9 in FIG. 4 has a built-in cold storage device (not shown) that is cooled by a built-in cooling unit (first cooling device) and stores cold.

Therefore, when the heat-insulating container 9 is loaded onto the carrier vehicle 11, cooling is continued by the cold air from the cold storage device.

At pace 12:, the insulated containers 8, 9 are unloaded from the carrier 11 along with other containers 14, and the articles are appropriately sorted. In addition, in Pace 12, the insulated container is 8.9
In both cases, the interior of the refrigerator is continuously cooled by a built-in cooling unit that is powered by the product's power supply.

Sorted items are stored in insulated containers 8 and 9 and other containers 1
4, and other paces (by transport vehicle) 16
station) 17.

This traveling vehicle 16 has the same configuration as the horizontal carrying vehicle 11, and therefore, as shown in FIG. 5, it continues to be cooled by a device capable of cooling the inside of the heat-insulating container 8 in FIG. 3.

At the pace 17, similar to the above-described pace 12, the insulated containers 8, 9 and other containers 14 are unloaded from the service vehicle 16, and the articles are sorted. This pace 17
However, it goes without saying that the interiors of the insulated containers 8 and 9 continue to be cooled using commercial power.

Sorted items are stored in insulated containers 8 and 9 and other containers 1
4 and transported to another center (station) 19 by a horizontal carrier (transport vehicle) 18.

It goes without saying that this horizontal carrying vehicle 18 is similar to the horizontal carrying vehicle 11 described above.

From the center 19, goods are delivered to households 2 by collection and delivery vehicles 21.
2 and each office 23. It goes without saying that this collection/delivery vehicle 21 is similar to the aforementioned collection/delivery vehicle 4.

According to the above-mentioned individual goods delivery system, neither the centers 7 and 19 nor the paces 12 and 17 need to have fixed cooling equipment such as a frozen warehouse.

It becomes possible to individually deliver items that require refrigeration. Moreover, collection and delivery vehicle 4.2
1. Horizontal carriage 11, 18. Since the items requiring refrigeration can be transported together with other items in both the vehicle 16 and the service vehicle 16, there is no need to transport the items requiring refrigeration and other items separately.

Note that it is preferable that the lower surfaces of the heat-insulating containers 8 and 9 be provided with wheels or the like to facilitate movement.

In the above description, the first cooling device is built into the heat insulating containers 8, 9, but the first cooling device may be installed in the center 7, 19 or paces 12, 17. In that case.

The first cooling device can be configured similarly to the cold air unit 13. - An example is shown in FIG.
