Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf facility in which a movable shelf having a plurality of compartment storage spaces in the vertical direction and the lateral direction is provided, and a work space can be formed in front of the movable shelf.

[0002]

2. Description of the Related Art Conventionally, as this kind of shelf equipment, for example, the shelf equipment found in Japanese Patent Application No. 3-345688 has been provided. According to this conventional shelf facility, when loading and unloading a load, first, an empty loading / unloading device is located outside the work space, the movable rack group is moved, and the work space is set in front of the target compartment storage space. Then, the loading / unloading device is moved in the front-rear direction by the support guide on the girder side and positioned outside the end of the working space. Then, while the load is being received from the load receiving cart by the operation of the loading / unloading device, the girder is moved by the support guide of the crane rail to move the loading / unloading device in the work space, and stop it so that it faces the front of the target compartment storage space. After this, the loading / unloading device is activated.

In addition, in order to unload the cargo, an empty loading / unloading device located outside the end of the work space is moved in the work space in the same manner as described above so as to face the front of the intended compartment storage space. Then, the load is taken out by activating the loading / unloading device. And the loading and unloading device that supported the load and came out from the work space to the handling area,
This can be done by delivering the load to the receiving cart by the operation.

At this time, the crane rail for supporting and guiding the girder is arranged between the upper ends of the outer columns forming the fixed shelf via a fixing member (support plate). One end of the crane rail in the length direction extends above the material handling area and is supported on the floor side by auxiliary columns. The girder is supported and guided by a collared wheel on both crane rails.

[0005]

According to the above-mentioned conventional structure, by disposing the crane rail between the upper ends of the support columns, the load of the loading / unloading device, the girder, etc. is fixed on the fixed shelf side through the multiple support columns. Although it can be supported stably, its position is necessarily right above the outer column, which increases the length of the girder and makes it larger due to its bending (stiffening). It must be done and it becomes heavy.

Further, since the girder is supported and guided by the crane rail through the collared wheel body, it is easy for the girder to swing in the lengthwise direction and to ride on the wheel body (wheel removal). For this, a collarless collar mounted on the crane rail,
A type in which a pair of guide rollers that are guided to both side surfaces of the crane rail are provided is conceivable. However, according to this, the outer guide rollers are located outside the crane rail, so the girder becomes even longer. Moreover, since the girder projects outward from the outer surface of the fixed shelf, the outer surface of the fixed shelf cannot be arranged sufficiently close to the surrounding wall body, resulting in a large dead space.

It is not sufficient in strength to support one end of the crane rail on the floor side only with the auxiliary columns.
Furthermore, the structure and control become complicated by providing the receiving cart at the loading / unloading area. On the other hand, it is conceivable to provide a fixed load cradle outside the end of the fixed shelf, but in this case, the transfer of the load by the forklift to the fixed load cradle must be performed while avoiding the auxiliary columns, A space for that purpose must be secured, for example, outside the outer surface of the fixed shelf, that is, outside the width in the front-rear direction of the shelf equipment.

The object of the present invention is to support the load on the girder side in a stable manner, but the girder can be shortened in length and can always run stably, and the forklift with respect to the loading platform can be used.

And a rail is disposed between the left and right beam members at the middle portion in the length direction of the beam member, and the rail is supported on the upper surface of these rails via a support ring and Guided to the outer surface via guide rollers Traveling freely girder provided, is provided to move freely out device supported by it and the left-right direction in the working space material handling hall in the longitudinal direction of the girders.

In the shelf equipment of the second aspect of the present invention, left and right rails are arranged on the fixed frame body, and the ends of these rails are supported by the support frame body arranged outside the cargo handling area. , At least one end portion in the front-rear direction of the support frame is
A notch is formed in the lower part, a cargo receiving stand is provided in the cargo handling area facing the notch, a girder supported by both rails is provided, and the girder is supported by the girder to move left and right in the work space. In addition, a loading / unloading device is provided that is movable in the front-rear direction in the loading and unloading area.

[0011]

In the structure of the first aspect of the invention described above, when a load is to be stored, the load is first passed to the loading / unloading device in the loading / unloading area via the load receiving stand or the like. Before and after this work, the movable rack is moved so that a work space is created in front of the target compartment storage space. The loading and unloading device supporting the load is then moved in the handling area and positioned outside the end of the work space. Then, by moving the girder, the loading / unloading device is moved in the work space, and the loading / unloading device is operated after the loading / unloading device is stopped by facing the front of the targeted partitioning storage space. Can be stocked.

Further, in order to take out the load, an empty loading / unloading device located outside the end of the working space is moved in the working space so that it faces the front of the target compartment storage space in the same manner as described above. Then, the load is taken out from the intended compartment storage space by operating the loading / unloading device after stopping the load. Then, the loading / unloading device supporting the load can be moved within the work space and positioned in the loading / unloading area.
