Article storage equipment

Abstract

Disclosed is an equipment for storing articles. One end of a wirerope 7 is connected with a raising platform 6 and the other end is connected with a compensating counterweight through a driving wheel 9 which is driven by a motor M to cause the raising platform 6 to go up and down. The raising platform 6 is provided with a glide clamp plate 32 that transmits vehicles C in and out of a carbarn between the raising platform 6 and a storage shelf 3 in the horizontal direction when the raising platform 6 parks at the side of the storage shelf 3; and the raising platform 6 is also provided with a positioning device 57 which positions accurately a lifter that parks at the side of the storage shelf to be at an upper and a lower positions relatives to the storage shelf according to the up-and-down displacement of the glide clamp plate 32. A control device is arranged for controlling the motor linked with the displacement to keep the wirerope 7 in basically even tension before and after the positioning device 57 displaces upwards and downwards.

Description

Technical field [0001] The invention relates to an article storage device for transferring articles between a lifting body and a storage shelf. Background technique [0002] Generally, in an item storage facility such as an elevator-type three-dimensional parking facility, in order to store items such as inbound vehicles and other items on the storage shelves, or to remove items such as outbound vehicles from the storage shelves, it is necessary to use the elevator platform The goods such as vehicles entering and exiting the warehouse are transported between the elevator body and the storage rack provided adjacent to the elevator corridor of the elevator body. Then, the lifting body is connected to one end of a linear member such as a wire rope, and the other end of the linear member is connected to a counterweight through a driving sheave, and the winding or unwinding of the linear member is operated to make the lifting body follow The hoistway is raised and lowered, and the dri...

Problems solved by technology

[0005] However, in this article storage device in the past, the positioning of the lifting body is carried out when the lifting body is stopped at the side of the storage rack by the lifting drive device and when the driving of the driving sheave is in the stopped state. Keep it at the upper position when the body is positioned. At this time, the reduction and relaxation of the tension will occur on the one end side of the linear component relative to the drive sheave (on the side of the lifting body), and the other side of the linear component relative to the drive sheave. One end side (the counterweight side) has a large tension difference, which causes frictional sliding on the drive sheave, resulting in significant damage to linear parts

Moreover, the lifting body is lifted and lowered by a plurality of linear parts, and the tension generated on the side of the lifting body of each linear part is different due to the weight balance of the article, which makes the sliding of the linear part on the driving sheave As a result, it is easy to produce unbalanced slack on the side of the lifting body on each linear part. In this state, once the positioning of the lifting body is released, the horizontal balance of the lifting body will be unbalanced.
