Friction drive device, cross-belt sorting machine and cross-belt sorting system

Abstract

The invention discloses a friction drive device, a cross-belt sorting machine and a cross-belt sorting system. The friction drive device comprises at least one pair of drive wheels keeping a micro-clearance and provided with parallel axes, wherein the two drive wheels can be rotatably arranged on an installation plate and are driven by one same motor so as to self-rotate; and the self-rotation directions of the two drive wheels are opposite. The friction drive device with the scheme is ingenious in design and simple in structure; through arranging a special belt driving mechanism, one motor drives the two drive wheels to rotate, so that compared with an existing friction drive structure, one motor is omitted, the equipment cost is greatly reduced, meanwhile, the energy consumption of the single motor is low compared with the operation energy consumption of two motors, and meanwhile, a transmission mechanism is low in maintenance and replacement cost.

Description

technical field [0001] The invention relates to the field of logistics sorting, in particular to a friction drive device, a cross-belt sorter and a cross-belt sorting system. Background technique [0002] The cross-belt sorter is a commonly used sorting equipment in logistics sorting. It is connected by the main drive belt conveyor and the trolley (referred to as "trolley") carrying a small belt conveyor. When the "trolley" moves When reaching the specified sorting position, turn the belt to complete the task of sorting and sending out the goods. [0003] The existing trolley drive method is often the way of motor + sprocket + chain. On the one hand, the trolley needs to be connected to the chain, which increases the difficulty of assembly. On the other hand, due to the pitch limit of the chain, the gap between the trolleys is relatively small. large, resulting in a reduction in the number of trolleys; and, due to the limited number of power points, in order to ensure suffi...

Problems solved by technology

[0003] The existing trolley drive method is often the way of motor + sprocket + chain. On the one hand, the trolley needs to be connected to the chain, which increases the difficulty of assembly. On the other hand, due to the pitch limit of the chain, the gap between the trolleys is relatively small. large, resulting in a reduction in the number of trolleys; and, due to the limited number of power points, in order to ensure sufficient driving force, the length of the chain often needs to be controlled within a reasonable range, and the limitation of the chain length hinders the extension of the loop , is not conducive to line expansion

[0004] There are also some cross-belt sorters that are driven by friction-driven power, such as the Chinese patent application number 201720689640.7, which uses two motors to drive the two rollers to rotate respectively, so that it is located between the two rollers. Although this structure solves the deficiency of chain drive, it needs two motors, which increases equipment cost and energy consumption.
