Rotary roller deflection type sorting device and logistics sorting system

Abstract

The invention discloses a rotary roller deflection type sorting device and a logistics sorting system. The rotary roller deflection type sorting device comprises a rack, wherein a group of sorting units are arranged on the rack, each sorting unit comprises a deflection seat, a group of rotary rollers with parallel axes and equal heights are horizontally arranged on each deflection seat, the heightof a conveying surface formed by the rotary rollers is larger than the height of the deflection seat, and the rotary rollers are directly or indirectly driven by a driving roller which is parallel tothe axes of the rotary rollers and is driven by a power source; and each sorting unit can rotate around a longitudinal axis of a corresponding mounting seat and is connected with a deflection drivingdevice for driving the corresponding sorting unit to self-rotate. According to the scheme, one group of rotary rollers are arranged on one deflection seat, so that the number of the deflection seatscan be effectively reduced, the overall structure is simplified, and the dead weight of equipment is reduced; and meanwhile, the multiple rotary rollers are driven by adopting a friction driving mode,so that the driving mode is simple and easy to achieve, no interference exists between the driving mode and the deflection of the rotary rollers, and the stability is good.

Description

technical field [0001] The invention relates to the field of logistics equipment, in particular to a roller deflection sorting device and a logistics sorting system. Background technique [0002] The goods reversing methods in the modern automated intelligent sorting system mainly include swing arm type, flap type, turntable type, push head type, slider type, deflection type, etc. [0003] Among them, the deflection type sorting specifically includes deflection wheels, deflection balls, deflection conveyor belts, etc., deflection wheel type, such as the Chinese patent application number 201721094362.7 discloses a roller type steering transfer machine, which is deflection wheel type, which makes The rollers are rotatably arranged on the deflection base, and the deflection base can be rotated by itself, and the rotation of the deflection base drives the rotation of the rollers, thereby realizing the turning of objects passing the rollers. [0004] The problem with this struct...

Problems solved by technology

[0004] The problem with this structure is that each roller needs a deflection seat, and the increase in the number of rollers will result in an increase in the number of deflection seats, resulting in a complex structure and heavy weight.

The design of the special structure of each deflection seat also increases the gap between the deflection wheels, increasing the risk of material jams

[0005] In addition, in this structure, the drive of the roller is connected to the second transmission shaft 71 through the O-ring, but since the roller is fixed on the deflection seat and rotates with the deflection seat, the O-ring needs to be twisted and deformed after the roller deflects, and After the O-ring is twisted, it will not be able to continue to transmit torsion, which will cause the roller to be unable to continue to be driven by the O-ring to rotate after rotating with the deflection seat, and it will not be possible to realize the transportation of the goods. This design is obviously unreasonable.

[0006] At the same time, the deflection base rotates through two bearings, but the bearings are bearings in the form of relative rotation of the inner and outer rings. The problem with this structure is that the bearings bear a large load and are prone to damage.

[0007] Deflection belt type, such as the belt type sorting disclosed in the application number 201910207235.0, which arranges two belt sorting units on one deflection seat. Although this structure is beneficial to reduce the number of deflection seats, the drive of the belt conveyor Still through the roller drive structure similar to the above-mentioned embodiment, there are also the above-mentioned problems

[0008] At the same time, the arrangement of multiple sorting units is unreasonable, and the gap between adjacent sorting units is relatively large, which increases the risk of material jams
