Description

Multilayer linear circulating conveyor and double-sided trolley thereof

Technical Field

The invention relates to logistics equipment, in particular to a multilayer linear circulating conveyor, a double-sided trolley and a method for realizing conveying and sorting.

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 the object (letter sorting dolly) and carries the thing face only one side, uses at orthoscopic sorting machine, the year thing face of original when it moves another layer is down, the dolly will be unable to carry the thing this moment, this layer just also can't carry the thing letter sorting, it all faces up to improve the utilization ratio realization every layer year thing face of this kind of dolly, need do auxiliary structure when rising decline and make the dolly turn-ups not, still need adopt complicated mode to solve the wiring circular telegram and the communication problem of every dolly 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.

Patent application No. CN209635286U, which discloses a cross-belt sorter that runs in a vertical direction, has the disadvantage of not having a load-carrying function when the carts are moved under the apparatus.

The patent application with publication number CN 211870565U discloses a cross belt sorter running in the vertical direction, in which the trolleys are designed in an upper and a lower double layer, both layers can be used for placing goods, the trolleys move circularly along the rail, 180-degree horizontal turnover can occur during the movement, the goods on the upper layer of the trolleys can be sorted before the turnover, and the goods on the lower layer of the trolleys fall from the lower layer of the trolleys to the reverse side of the upper layer of the trolleys after the turnover, and then the goods are sorted. This patent is fallen easily at dolly upset in-process goods, and the structure is complicated to be unfavorable for maintaining moreover.

Chinese patent document CN108686965A discloses a sorting unit, which is connected end to end in a ring shape, and runs along a vertical ring track surface in a circulating manner, and secondary structural members are installed at the bottom of each sorting trolley, so that although the problem of noise generated during the operation of the sorting system can be solved, the lower sorting trolley cannot sort goods, which causes waste in space, and if a double-sided trolley can be designed at the time, the lower sorting space is utilized, and the sorting efficiency is increased by one time immediately.
