Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, and more particularly to a reversing conveying device. Background Art

[0002] In the airport baggage conveying system, an empty basket system is used to transport empty baskets to place irregularly shaped luggage when passengers check in. During the transportation path planning process, the empty basket conveying system needs to cooperate with the airport civil engineering, conveyors, etc. to carry out reasonable path planning, which makes the path planning of the entire system complicated and generates many branches. In the vertical merging and diverting conveying lines, a lifting and reversing conveying device is required to realize the vertical reversing conveying of empty baskets.

[0003] Currently, the existing lifting and reversing conveying devices on the market mostly adopt a structural model that combines rollers and lifting devices. The lifting device lifts the material off the original conveyor line surface and then the conveying device on the lifting device that is perpendicular to the original conveyor line transports the material to the vertical branch line.

[0004] Currently, most lifting mechanisms use pneumatic lifting or a reduction motor driving a connecting rod mechanism to lift on a fixed guide rail. This mechanism is complex and the equipment occupies a large vertical clearance space. It is not suitable for special spaces requiring small equipment clearance height space or for occasions where the owners of related projects require the use of electric rollers for controlled conveying. Alternatively, there are related transfer conveyors currently available on the market that use electric rollers to drive eccentric wheels to lift and lower the structure. This meets the need to reduce the height space of the equipment, but the electric roller drive mechanism is complex. For example, Chinese patent application number CN202021577567.2 discloses a roller transfer conveyor. The technology disclosed in this patent has the following deficiencies:

[0005] 1) The eccentric wheel lifting mechanism includes a first roller and a second roller symmetrically installed on the transverse inner wall of the mounting basket, and two sets of symmetrically distributed linkage roller assemblies on the lifting frame. The repeated addition of rollers and roller assemblies reduces the transmission efficiency of the equipment. The first roller and the second roller also need to convert power transmission through a synchronous belt, which is not conducive to the maximum efficiency of the mechanism.

[0006] 2) The horizontal transfer component does not have the function of preventing the conveyor belt from deviation. During the material conveying process, maintenance personnel are required to adjust the belt deviation from time to time. At the same time, the tension of the conveyor belt also needs to be adjusted from time to time by maintenance personnel.

[0007] Therefore, developing a reversing conveying device with stable and reliable structure is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0008] In view of this, the present utility model provides a commutation conveying device with stable and reliable structure.

[0022] Preferably, a connecting rod is connected between two opposite rotating connecting plates at both ends of the lifting roller. The connecting rod can enable the four rotating connecting plates at both ends of the lifting roller to move synchronously.

[0023] Preferably, the commutation conveying assembly includes: a transfer knife plate, conveying rollers, and a conveying belt; a plurality of conveying rollers are provided and rotatably connected between two parallel transfer knife plates; the conveying belt is wound around the outside of the conveying rollers.
