[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a shelf traveling path along which a plurality of movable shelves having an article storage section travel, and a transfer means capable of loading and unloading articles into and from the article storage section of the movable shelf. The transfer traveling path on which the transfer traveling body travels is arranged in a state of intersecting with each other in a plan view, and in the shelf traveling path,
Rolling rack wheels provided in the lower part of the moving shelf, a shelf rail for supporting the moving shelf so that it can travel is provided, and in the transfer traveling path, below the transfer traveling body. The present invention relates to an article storage facility provided with a transfer rail that rolls the provided transfer wheels to movably support the transfer traveling body.

2. Description of the Related Art The article storage facility includes a shelf traveling path along which a plurality of movable shelves travel, and a transfer traveling body equipped with a transfer means capable of moving articles into and out of an article storage portion of the movable shelf. The transfer traveling path to be traveled is arranged so as to intersect with each other in a plan view, and a desired moving shelf is provided by traveling along the shelf traveling path of the moving shelf and traveling along the transferring traveling path of the transfer traveling body. In the related art, it is possible to take out and put in an article, but conventionally, a fixture provided with a shelf rail and a transfer rail separately at the intersection where they intersect with each other, corresponding to each of them. Are separately fixed to the installation surface side (see, for example, JP-A-6-107307).

[0003]

Therefore, when the shelf rail and the transfer rail are fixed at their intersections, the relative positions of the rails, that is, the relative positions in the horizontal direction and the vertical direction are positioned. Must be performed while associating each rail with each other.For example, when positioning the other rail based on the position of one rail, if the position of the reference rail changes, It is necessary to reposition the other rail while referring to the position, and there is a drawback that the fixing work requires a lot of trouble and labor. The present invention has been made in view of the above circumstances, and by devising a rail fixing means at an intersection of a shelf rail and a transfer rail, the work for fixing these rails can be simplified. The purpose is to

[0004]

According to a first aspect of the present invention, there is provided an article storage facility, wherein a shelf traveling path along which a plurality of movable shelves having an article storage section travels and an article storage section of the movable shelf. Is arranged in a state where the transfer traveling path along which the transfer traveling body equipped with a possible transfer means travels intersects with each other in a plan view, and the shelf traveling path is for a shelf provided under the movable shelf. A rack rail for rolling the wheels to support the movable rack so that the rack can travel is provided, and a transfer wheel provided under the transfer traveling body is rolled on the transfer traveling path. And a transfer rail for movably supporting the transfer traveling body, wherein the shelf rail and the transfer rail are intersecting portions where they intersect each other. At, since it is fixed to the installation surface side by a common rail fixture, If positioning the common rail fixtures each rail with respect to each other, as a result, will be the relative positions of each other these rails are positioned, it can be positioned without associating each of the rails to each other. Therefore, the work of fixing the shelf rail and the transfer rail can be easily performed.

According to a second aspect of the present invention, in the article storage facility, the rail fixture has a continuous support portion capable of supporting one rail of a traveling route in a continuous or substantially continuous manner and a rail of the other traveling route. Since there are provided intermittent supporting portions that can be intermittently supported while sandwiching the rail supported by the continuous supporting portion, each of the rails is divided at the intersection, and each of the four rail end portions is divided. As compared with the case where the rails are fixed to the installation surface side by a common rail fixing tool, the fixing work of those rails can be further simplified.

According to a third aspect of the present invention, in the article storage facility, a rail for a shelf is supported on the continuous support part, the rail for transfer is supported on the intermittent support part, and the rail for transfer is supported on the transfer rail. , A rolling direction guide surface for guiding the rolling direction of the transfer wheel is formed by engagement with an annular flange formed to project in the radial direction along the peripheral surface of the transfer wheel. Since the rail is supported by positioning the rolling direction guide surface at a position higher than the shelf rail supported by the continuous support portion, the shelf rail supported by the continuous support portion is, The wheel rolling surfaces of the shelf rails are arranged flush with each other without the need to provide a recessed groove or the like for allowing passage of the annular collar of the transfer wheels guided along the transfer rails. As a result, a moving rack having a relatively large weight can be smoothly run along the rack rail.

In the article storage facility according to claim 4, since the rail supporting surface of the intermittent supporting portion is arranged at a position higher than the rail supporting surface of the continuous supporting portion, the height dimension is low, and therefore, The light-weight and easy-to-handle transfer rail can be fixed to the installation surface side, and its rolling direction guide surface can be arranged at a position higher than the shelf rail supported by the continuous support portion.
