Description

  The present invention provides a rack unit connecting bracket that can connect four rack units when rack units as a single rack having shelves for storing articles are assembled in multiple stages, and a rack unit connected by the bracket. The present invention relates to a connection structure and a rack unit connection method using the same bracket.

A steel pallet “nestenor” is widely known in the logistics industry and the like as a rack unit used for storing and storing articles such as merchandise.
This “nestenor” can be assembled in multiple stages and can be stacked when not in use, so it is used in distribution warehouses as a rack that can effectively utilize limited space.
This “nestainer” has a shelf plate at the bottom, a regular nestenator with an open top, and a product that can be placed directly via a pallet etc. with the bottom open, and a top plate on the top. Although there is a nestainer, in this document, there is a case where it is simply described as “nestainer” regardless of whether it is a forward / reverse nestainer.

  One of the problems to be solved in these “Nesstainers” is that when “Nesstainers” assembled in multiple stages are not stably placed in warehouses, etc., when external force is applied to each “Nesstainer”, The product stored in the “Nesstainer” may drop or fall and be damaged, and if each “Nesstainer” is applied with more force from the outside, it loses its balance and falls. These concerns are particularly problematic during earthquakes and the like.

In order to solve such a problem, various technical devices have been devised conventionally.
For example, in Patent Document 1, in a multistage storage rack 1 formed so as to hold a pallet 6 on which an article 5 is placed, vibration caused by an earthquake or the like can be absorbed in a portion 7 that holds the pallet 6. Arrangement of cushion bodies 10 that can be performed in a dispersed manner or a planar manner is performed (see FIG. 1 of the same document 1).
A similar configuration is also disclosed in Patent Document 2.

  In such a configuration, “when the article is stored and placed on the pallet of the storage rack or storage frame with the article placed on the pallet, the pallet is supported so that the cushion body grips from below. Even when an earthquake occurs, it can absorb the shaking sufficiently to prevent the pallet from moving or dropping and preventing the stored items from falling or breaking. It is said that it can be done "(paragraph 0009 of Patent Document 1).

However, these prior arts do not disclose a technique for improving the stability of the storage rack or the storage frame itself even if the product can be prevented from dropping or breaking.
The applicant has traditionally decided to bind the “nestainers” on the top, bottom, left and right using cloth belts or connect them with metal belts in order to stabilize the multi-stage “nesteners”.
However, in the connection method of “Nesstainer” using these bands, when placing the pallet on the “Nesstainer” using a forklift, the end of the pallet may hit the band (details will be described later). As the damage of the band progresses, maintenance such as replacement of the band is necessary.

In addition, when the pallet was put in and out of the “Nesstainer”, it was necessary to use nerves to operate the forklift so that the pallet would not get caught by the belt.
Furthermore, when the “nestainer” was assembled in three stages, the band attached to the third stage “nestainer” was difficult to see and was troublesome to maintain because it was high. .
