Turntable air-sweeping type tobacco sorting system controlled by PLC (Programmable Logic Controller) control system

Abstract

The invention provides a turntable air-sweeping type tobacco sorting system controlled by a PLC (Programmable Logic Controller) control system. The turntable air-sweeping type tobacco sorting system comprises the PLC control system, a tobacco transfer device for transferring tobacco, a tobacco detecting device for detecting appearance information of tobacco on the tobacco transfer device, and a sorting device; the tobacco detecting device detects the appearance information of the tobacco on the tobacco transfer device and transmits the appearance information to the PLC control system, and then the PLC control systems controls the sorting device to sort according to the received information; a solenoid valve is controlled by the PLC control system to be switched on and off so as to control a nozzle to sweep air; the PLC control system also controls a three-phase motor to stop as well as controls the solenoid valve to sweep air according to the information received from the tobacco transfer device, and thus the tobacco can be swept into a collection box. With the adoption of the turntable air-sweeping type tobacco sorting system, the tobacco sorting speed is increased; and the PLC control system controls the sorting system to realize automatic sorting of the tobacco, so that the reduction of the labor cost is achieved.

Description

technical field [0001] The invention relates to a tobacco leaf sorting device, in particular to a turntable air blowing tobacco leaf sorting system controlled by a PLC control system. Background technique [0002] Tobacco is an important economic crop and occupies an important position in my country's agricultural production. Flue-cured tobacco is an important raw material for the cigarette industry, and the quality of its tobacco leaves directly affects the process formula and production quality of tobacco leaf products. Traditional tobacco leaf sorting operations are usually completed by professionally trained sorting personnel, relying on their professional skills, senses, vision and touch, which consume a lot of resources and a large amount of labor; the sorting process is labor-intensive and efficient. Low, and the sorting personnel are easily affected by factors such as environmental conditions, emotions, and experience, and cannot sort the tobacco leaves to a specifi...
