Description

Multilayer linear circulating conveyor

Technical Field

The utility model relates to a logistics equipment especially relates to a multilayer straight line endless conveyor.

Background

The existing market is mainly provided with a loop-line crossed belt type sorting machine, but the equipment is horizontally paved on the ground, the occupied area is large, and the equipment is difficult to be applied to a small field, so that a linear crossed belt type sorting machine is researched, a plurality of movable objects (called sorting trolleys for short) are connected in series on a fixed track to form a cycle, compared with the traditional annular crossed belt type sorting machine, the linear crossed belt type sorting machine is not paved horizontally any more, but is formed into a multilayer type in the vertical direction, the linear crossed belt type sorting machine is developed in a small space under the condition of small occupied area, and the utilization rate is improved.

The removal of conventional cross band sorting machine carries object (letter sorting dolly) and carries the thing face only one side, uses at orthoscopic sorting machine, and the thing face of carrying originally when it moves another layer is down, and the dolly will be unable to carry the thing this moment, and this layer just also can't carry the thing letter sorting, will improve the utilization ratio and realize that every layer of thing face of carrying of this kind of dolly all faces up, need do auxiliary structure when rising decline and make the dolly turn-over not, still need adopt the wiring circular telegram and the communication problem of every dolly of complicated mode solution simultaneously. If the trolley is turned over, the layer of the trolley with the carrying surface facing downwards cannot be used for transferring articles, and the site utilization rate and the use flexibility are greatly reduced.
