Abstract

PURPOSE: To elevate and lower a guided section provided on an elevating base smoothly in a less noise condition by providing an elevating guide mechanism which prevents horizontal traveling and guides in such a manner that it can ascend and descend freely on each support column at both side ends of a storage shelf on the opposite side to a storage shelf of an article carry-in-and-out section. CONSTITUTION: An elevating guide mechanism 39 is provided on a support columns 8 at both ends in the lateral direction on the opposite side to storage shelves 2A, 2B provided with an article carry-in-and-out section 4. Compared with the case where the elevating guide mechanism 39 is provided on support columns 8 of the front and rear storage shelves 2A, 2B, dimensional error between each guided section 33 of the elevating base 5 and it is reduced and smooth ascent and descent can be performed because a plurality of support columns 8 are longitudinally and vertically connected by shelf constituent members and the elevating guide mechanism 39 is provided by each support column 8 of one storage shelf as frame structure. Furthermore, the storage shelves 2A, 2B of the elevating guide mechanism 39 employ more shelf constituent members, have grater rigidity, and can suppress vibration caused by the elevating base more easily than the storage shelves on the opposite side which require larger space than a storage section 1 to constitute an article carry-in-and-out section 4.

A strip formed by bending to form an L-shaped cross-section, a strip formed by bending to form a U-shaped cross-section, a rod having a circular or elliptical cross-section,
Alternatively, it may be carried out by changing to various shapes such as a shape obtained by combining these.

(2) In the above-described embodiment, the guided portion on the lifting table side is guided by sandwiching both lateral side surfaces and front and rear side surfaces of the lifting guide mechanism with a pair of rolling rollers. However, instead of such a configuration, the following configuration may be adopted. The outer surface of the elevating guide mechanism is formed in an arc shape, and the outer peripheral portion of the rolling roller is formed in a medium-thin shape with a smaller diameter toward the center along the arc outer surface. A groove with an arc cross section on the outer surface of the elevating guide mechanism. Are formed along the vertical direction, and the rolling roller is formed in a spherical shape, and various configurations such as guiding to prevent horizontal movement while sliding on the outer surface of the elevating guide mechanism in a fixed position. It may be changed to.

(3) In the above embodiment, the balance weight is arranged on one lateral side of the lift table. However, a pair of balance weights are provided on both lateral sides of the lift table, and both lateral directions of the lift table are provided. The parts may be individually suspended and supported.

(4) In the above-mentioned embodiment, the cord is driven to rotate by the driving means. However, the lifting table or the balance weight is directly moved up and down by using a screw feeding mechanism, a cylinder device or the like. It may be configured.

(5) In the above-described embodiment, the lifting table is configured to be suspended and supported by the cord body together with the balance weight. However, the lifting body is raised by winding the string body by the driving means. It is also possible to adopt a configuration in which the elevating table is lowered by feeding it out.

(6) In the above-described embodiment, the front and rear sides of each of the lateral sides of the lift, that is, four positions are suspended and supported. However, in addition to such a structure, The central portion in the direction may be separately suspended and supported by a cord body, or the front and rear intermediate portions on both lateral sides may be suspended and supported by two cord bodies.

(7) In the above embodiment, the case in which small articles are loaded as the article to be stored has been described as an example, but a single product having a predetermined shape may be stored as the article. The structure of the article is not limited.

It should be noted that although reference numerals are given in the claims to facilitate the comparison with the drawings, the present invention is not limited to the configurations of the accompanying drawings by the entry.
