Description

  The present invention relates to a loading / unloading shielding device used when loading and unloading a load from a container of a transport truck such as a cold car in a distribution warehouse or the like equipped with a refrigeration refrigerator.

  When loading and unloading cargo between the distribution refrigerator and the container of the transport truck, the cold air escapes from the loading / unloading port of the distribution refrigerator and the outside air enters and raises the temperature inside the container. There was a need to prevent.

  Therefore, conventionally, a dock shelter that can cover the outside of the container part of the truck is provided outside the loading / unloading part of the logistics refrigerator to prevent entry of dust and the like, and the rear end part of the truck container is provided. A cushioning material is attached to the platform at the loading / unloading section of the logistics refrigerator, and the truck's rear end is brought into contact with this cushioning material to stop the truck. It is known to prevent cold air from leaking through a gap with the platform end.

  In addition, a plurality of elongated plates are wrapped in a rubber-like body to form a band-shaped shielding plate, and the shielding plate is folded in a bellows shape and stored in a storage container, and placed on a platform. An apparatus has also been proposed in which a shield plate is hung so as to cover the gap between the platform and the platform of the truck to prevent the dissipation of cold air (see Patent Document 1).

JP 2003-128263 A

  However, the shape and height of the loading platform vary depending on the vehicle type of the transport truck, and the height of the loading platform varies depending on the loading state of the load. For this reason, there is a difference in height between the height of the cushion material provided on the platform of the refrigerator for logistics and the height of the loading platform of the truck that has arrived at the platform, making sure contact impossible, and when loading and unloading the load There has been a problem that cold air escapes downward through the height difference portion or the uneven gap at the rear end of the loading platform, or the outside air and dust below enter the container through this clearance. Further, simply providing a shielding plate is insufficient in sealing between the container and the refrigerator for distribution, and it is difficult to say that the conventional problems are completely solved.

  The present invention solves these problems and can close and close the gap between the platform and the container of the truck, and cold air escapes from the loading / unloading portion of the logistics refrigerator and outside air enters and enters the inside of the container. It is an object of the present invention to provide a logistics container loading / unloading shielding device that can reliably solve the problem of temperature rise.

  Therefore, the logistics container loading / unloading shielding device according to the present invention is a logistics refrigerator-freezer of a type in which a truck container is brought close to a platform provided at a loading / unloading section of a logistics refrigerator-freezer, and a cargo is loaded and unloaded. The first feature is that a shock absorber made of an elastic tube that shields a gap between the container of the truck and the rear end of the loading platform is provided. The second feature is that the buffer body is movable up and down and / or back and forth. Furthermore, the third feature is that the buffer body is swingable in a front-rear oblique direction with respect to the loading / unloading port.
