Automatic warehouse

Abstract

It is an object of the present invention to provide an automatic warehouse in which an article housing portion is constructed by installing a plurality of strut units parallel with one another, the strut units each having a large number of shelf members arranged in a vertical direction and extended between a pair of strut bases arranged in a direction in which articles are housed, the automatic warehouse housing articles each having projecting portions such as hand gripping portions on its sides, wherein the hand gripping portions of the article and the strut bases located at the front and rear of the article are prevented from interfering with each other and wherein the articles can be housed more efficiently in the automatic warehouse without increasing the size of a housing space for each article. One of the pair strut bases 21 B is arranged closer to the other strut member 21 B, located at the loading and unloading side of the article 8. That is, the former strut base is retreated so as not to interfere with the projecting portions 8 a provided on the sides of the article 8. Further, a cylindrical member 21 A is arranged between the pair of strut bases 21 B, 21 B and has an insertion hole 21 e through which an adjuster bolt 21 is inserted. The pair of strut bases 21 B, 21 B and the cylindrical member 21 A is integrally formed.

1 . An automatic warehouse in which an article housing portion is constructed by installing a plurality of strut units parallel with one another, the strut units each having a large number of shelf members arranged in a vertical direction and extended between a pair of struts arranged in a direction in which articles are loaded and unloaded, the automatic warehouse housing articles each having projecting portions on its sides, the automatic warehouse being characterized in that one of said pair of struts, which is located at the loading and unloading side of the article, is arranged closer to the strut, which is located further from the loading and unloading side of the article, and at a position at which the strut located at the loading and unloading side of the article does not interfere with the projecting portions on the sides of the article.  
     
     
         2 . An automatic warehouse according to  claim 1 , characterized in that said pair of struts is integrally formed, and a through-hole is formed between the pair of struts so that a member projecting from a floor surface is inserted into the through-hole.  
     
     
         3 . An automatic warehouse according to  claim 1  or  claim 2 , characterized in that a fitting groove is formed in each side of each of said pair of struts so as to extend in a longitudinal direction, and a fixture is engaged with each of the fitting grooves so that said shelf members are mounted via the fixtures.  
     
     
         4 . An automatic warehouse according to  claim 1  or  claim 2 , characterized in that groove portions are formed in a bottom surface of said article at opposite ends of the bottom surface located at the loading and unloading side of the article, and at a central position of the bottom surface located further from the loading and unloading side of the article, and outermost edges of each groove portion are arranged radially relative to its center so as to form three vertexes of an equilateral triangle, and in that positioning pins are projectingly disposed on each of said shelf members and engaged with holes formed at those ends of the bottom surface of the article which are located at the loading and unloading side of the article, and a rotation preventing member is provided at a tip portion of the shelf member.
