Item conveying device and item storage equipment equipped with it

Abstract

The invention provides an article transport apparatus. A lifting platform which is guided by four lifting guiding masts and is liftable is supported by four cable-shaped members. The four cable-shaped members are differently coiled on the upper end of a lifting guiding mast, an upper side rotating member which forms a driven rotating member, the lower end of the lifting guiding mast, and a lower side rotating member which is driven by a lifting driving device. The article transport apparatus is provided with a connecting member which connects the upper side rotating members which are arranged in the advancing / retreating direction of an article supporting member in the four upper side rotating members or the lower side rotating members that are arranged in the advancing / retreating direction of the article supporting member in the four lower side rotating members.

Description

technical field [0001] The present invention relates to an article conveying device which is arranged at corners of a rectangular shape in a plan view at a distance from each other and stands vertically in a posture along the vertical direction, and article storage facilities equipped with the same. Four elevating guide masts, an elevating platform that can be moved up and down freely by being guided by the above-mentioned elevating guiding masts, four cable-shaped bodies that suspend and support the above-mentioned elevating platform, and a plurality of coils that wrap the above-mentioned four cable-shaped bodies in different ways. A rotating body, and a transfer device arranged on the above-mentioned lifting platform for transferring articles. Background technique [0002] As an article conveying device as described above, there is known an article conveying device that is provided with four pieces that are arranged at a distance from each other at the corners of a rectang...

AI Technical Summary

Problems solved by technology

[0010] Therefore, compared with the case where four driving devices for lifting are used to equally share the load brought by the weight of the total weight of the lifting table and the weight of the article, it is necessary to increase the driving capacity of the driving device for lifting the protruding side. The drive unit for side lift is larger than the drive unit for lift side

[0011] In addition, in the case where the article support is freely protruded toward both sides of the advancing and retreating direction, it is necessary to make the driving device for lifting and lowering the two cable-shaped bodies located on one side of the advancing and retreating direction of the article supporting body, and the drive device for driving the two cables located on the other side in the advancing and retreating direction. The driving capability of both the lifting drive devices of the two cable-shaped bodies on one side increases, and the problem of increasing the size of all the four lifting drive devices occurs.
