Sorting device of automatic logistics conveying line

Abstract

The invention discloses a sorting device of an automatic logistics conveying line. The sorting device comprises a light-weight swing arm rotating with a rotating shaft as the axis. The light-weight swing arm is connected with a crank-link mechanism driving the light-weight swing arm to swing. The crank-link mechanism is connected with a motor. When the light-weight swing arm is in a shrinkage state, the connecting point of a driven rod and a crank of the crank-link mechanism is not located at the dead point position of the crank-link mechanism. According to the sorting device, due to the fact that the motor serves as a power source and control is conducted through a PLC system, the sorting precision and efficiency can be improved, no special air source is needed, the structure is simpler, and the light weight is achieved on the premise that the strength of the swing arm is guaranteed. Furthermore, the position of the connecting point of the driven rod and the crank is controlled when the swing arm is in the shrinkage state, the resistance at the dead point position of the crank-link mechanism can be utilized for making the swing arm decelerate in the retraction process, and stopping of the crank-link mechanism is facilitated. Meanwhile, the influence of internal force of the dead point position on starting of the crank-link mechanism can be avoided, and the crank-link mechanism can be conveniently driven to be started.

Description

technical field [0001] The invention relates to a sorting device, in particular to a sorting device for a logistics automatic conveying line. Background technique [0002] The automatic control system of the logistics conveyor line is mainly through the automatic identification function of the system and the conveyor line system to automatically and flexibly transport the items from one location to another accurately with the best path and the fastest speed, thus completing The space-time transfer of materials realizes the rapid classification and shipment of items. [0003] After the items are input through the assembly line, manually paste barcodes on various items, weigh them, and then input the barcodes of these items into the management system through a handheld barcode laser scanner. The management system compares each received barcode with the built-in After checking the standard and confirming the conveying route, it is then conveyed through the conveying line. When...

Problems solved by technology

[0005] This method has the following disadvantages, 1), the sorting speed cannot be accurately controlled, which affects the diversion and sorting efficiency, and the sorting error rate is high; 2), the suspension arm of the pneumatic actuator is not strong enough, and the speed and The swing angle is fixed and unchangeable; 3) It is necessary to set up a special air source for air supply. When the cylinder is working, the noise is large, the later maintenance is difficult, and the maintenance cost is high.
