Linear cross belt sorting machine

Abstract

The invention relates to the technical field of logistics industry equipment, and particularly relates to a linear cross belt sorting machine. The linear cross belt sorting machine comprises a drivingend mechanism, a driven end mechanism and a driving chain connected between the driving end mechanism and the driven end mechanism, and further comprises a trolley driven by the driving chain to walkand a tray belt conveyor installed on the trolley and used for sorting, wherein a driving disc is arranged in the driving end mechanism; a driven disc is arranged in the driven end mechanism; the driving chain is wound around the driving disc and the driven disc to form a closed loop running back and forth; a left walking wheel and a right walking wheel are arranged at the left end and the rightend of the trolley correspondingly; a left driving end U-shaped guide rail groove and a right driving end U-shaped guide rail groove for the left walking wheel and the right walking wheel to walk andguide correspondingly are formed in the driving end mechanism; a left driven end U-shaped guide rail groove and a right driven end U-shaped guide rail groove for the left walking wheel and the right walking wheel to walk and guide correspondingly are formed in the driven end mechanism; the driving disc and the driven disc are positioned between the left walking wheel and the right walking wheel; running is stable; and noise is low.

Description

technical field [0001] The invention relates to the technical field of logistics industry equipment, in particular to a linear cross-belt sorter. Background technique [0002] The linear cross-belt sorter is widely used in the sorting of items in the express delivery and e-commerce fields. As a similar derivative product of the circular cross belt, the linear cross belt sorter has many advantages such as small footprint, high sorting efficiency, low input cost, and great applicability in application scenarios, and has a broad market prospect. At present, the linear cross-belt sorter on the market has many areas to be improved in terms of structural details. For example, the vertical circular drive mode mainly includes linear motor drive and AC reducer drive traction chain. The linear motor structure design is complex and the production accuracy is high.

Problems solved by technology

At present, the linear cross-belt sorter on the market has many areas to be improved in terms of structural details. For example, the vertical circular drive mode mainly includes linear motor drive and AC reducer drive traction chain. The linear motor structure design is complex and the production accuracy is high. And the defect of high energy consumption of the equipment; the connection structure of the chain and the trolley components mostly adopts the way of transition connection blocks, and the movement track at the semicircle at the head and tail ends is irregular, which is easy to generate impact noise; the tensioning method of the chain is currently mostly adopts the overall The frame adjustment method, if the chain stretches after a period of use, the anchor bolts need to be removed, and then the overall frame is tensioned in translation, which is not only cumbersome but also affects the accuracy of the equipment in the later stage; the middle frame mostly uses a welded frame, and the processing accuracy is poor Moreover, the cost is high, etc., especially for the drive transmission, which has a greater impact on the structure

[0003] For example, the application number is 201910829998.9, which discloses a new type of linear cross-belt sorter, including a frame, a sorting trolley, a drive chain, a driving sprocket and a driven sprocket, and the sorting trolley is carried by the front row of load wheels and the rear row. The wheel is placed in the ring guide rail, the guide rail is fixedly connected to the frame, the driving chain is hinged to the middle of one end of the sorting trolley, the driving chain is sleeved on the driving sprocket and the driven sprocket, and the driving sprocket and the driven sprocket can respectively It is rotatably installed at both ends of the frame. The wheelbase of the front row of load-bearing wheels is smaller than that of the rear row of load-bearing wheels. Shaped section guide rails, the inner guide rails include two straight line section guide rails and descending arc section guide rails on the upper and lower layers that are disconnected from each other. The two ends of the frame are driven by two driving sprocket structures. The structure is relatively complicated, the stability is not high enough, and the vibration noise is relatively large.
