Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading / unloading port shielding device useful for loading and unloading a load from a transportation truck such as a cold storage vehicle in a distribution warehouse equipped with a refrigerating device.

[0002]

2. Description of the Related Art When carrying in and out a load between a distribution refrigerator and a transportation truck, cold air escapes from the carry-in / out port of the distribution refrigerator and outside air enters to form dew condensation in the refrigerator. However, there is a problem that dust, insects, etc. jump in, and it was necessary to prevent this.

[0003] Therefore, conventionally, a dock shelter capable of covering the outside of the cargo bed portion of the truck is provided outside the loading / unloading portion of the distribution refrigerator to prevent dust and insects from invading the truck. Stop the truck by abutting the rear end of the cargo bed on the platform of the loading / unloading port of the distribution refrigerator, and cool air from the gap between the rear end of the truck loading platform and the platform end when loading / unloading the load. There is known an example in which leakage is prevented.

As shown in FIG. 5, when a strip-shaped cushion material b having a D-shaped cross section is provided on the platform a along the platform a, and the rear end of the track c abuts on the platform a. The impact is relieved and a gap is not formed between the rear end of the track c.

[0005]

The height of the cargo bed portion differs depending on the type of the truck for transportation, and the height of the cargo bed portion also varies depending on the loaded state of the cargo.

Therefore, a height difference occurs between the height of the cushion material provided on the platform of the physical distribution refrigerator and the height of the cargo bed portion of the truck arriving at the platform, making it impossible to make contact with each other, so that the load can be carried in and out. Sometimes, there is a problem that cold air escapes downward through the gaps in the height difference portion, or outside air and dust below intrude into the distribution refrigerator through the height difference portion.

The present invention solves these problems and provides a loading / unloading shield device which can close the gap between the platform and the truck bed when necessary and can be easily removed when not needed. To aim.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention is for a physical distribution system in which a cargo bed section is brought close to a platform provided at a loading / unloading section of a physical distribution refrigerator to carry in and carry out a cargo. In the refrigerator, a foldable structure is provided that has a shielding plate that can be hung between the upper surface of the platform and the truck bed to cover the gap between the platform and the truck bed. Is characterized by.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIGS.

FIG. 1 shows a usage state of the shielding device in a distribution refrigerator 1 having a loading / unloading device according to the present embodiment. 1a is a loading / unloading part of the shipping refrigerator 1 and 1b is a loading / unloading part 1a. 2 is a platform, and the platform 2 is formed at substantially the same height as the floor surface of the loading / unloading portion 1a.

Reference numeral 3 denotes a shield plate which will be described later, and reference numeral 4 denotes a storage container which stores the shield plate 3 by folding it in a bellows shape and also serves as a car stop.

Reference numeral 5 denotes a dock shelter, which projects onto the distribution refrigerator so as to cover above the cargo bed portion of the truck 6 arriving at the platform 2 and, if necessary, laterally of the cargo bed portion. It is set up.

FIG. 2 is a cross-sectional view of the shield plate 3. The shield plate 3 has a plurality of elongated plate-like bodies 3a arranged side by side, and these are wrapped with a flexible rubber-like body 3b to form a band. It is formed and has a structure that can be folded in a bellows shape.

Next, the method of use and the operation of the loading / unloading device of the present embodiment will be described.

As a truck for loading and unloading a load to and from the refrigerator 1 for distribution, a truck 6 with a cold storage called a cold storage vehicle is used.
Are used, and they generally have a door for loading and unloading the rear end of the cool box.

As shown in FIG. 1, the rear end of the truck 6 is brought close to the platform 2 to stop, and at this time, the cushion material 7 having a D-shaped cross section provided on the front end of the platform 2 is attached to the rear end of the truck 6. If it does not contact the shield plate 3, the shield plate 3 is pulled out from the inside of the storage container 4 provided on the platform 2 and the end portion of the shield plate 3 is locked to the bed of the truck 6 or the rear end portion of the floor surface of the cool box. Try to cross 3.

As shown in FIG. 3, the shield plate 3 is folded in a bellows shape and accommodated in the storage container 4, and one end of the shield plate 3 is anchored in the storage container 4.

The shield plate 3 pulled out is the platform 2
And the cargo bed of the truck 6 are covered to prevent cold air from escaping downward and dust and insects from entering the refrigerator 1 for distribution.

In this embodiment, the storage container 4 is provided on the platform 2. However, as shown in FIG. 4, the storage container 4 is installed at the rear end of the loading platform of the truck 6. When necessary, the shield plate 3 may be pulled out from the storage container 4 and hung on the platform 2.

[0020]

As described above, according to the present invention, since the shielding plate to be hung between the loading / unloading portion of the refrigerator for physical distribution and the loading platform of the truck is foldable, the refrigerator for physical distribution is loaded and unloaded at the time of loading and unloading. It is possible to reduce the dissipation of cold air from the plant and save energy, reduce condensation in the distribution refrigerator, and prevent dust and insects from entering the distribution refrigerator.
Further, there is an effect that the work of pulling out and storing the shield plate can be easily performed.
