Problems solved by technology

The intermediate correction and guidance system is mainly composed of photoelectric sensors, controllers, and actuators. The photoelectric sensors detect the edge position or the position of the marking line to pick up the position deviation signal, and then output the position deviation signal to the controller. The controller performs logic operations to generate The control signal is used to control the actuator to correct the deviation when the material is running. The patent number applied by the inventor is 02221638.3. The DC servo photoelectric automatic deviation correction device has a single function, the controller uses an analog circuit, and the control accuracy is not high.

Abstract

The invention comprises a photoelectric sensor, a micro computer ratio controller and an intermediate error-correcting guiding unit. Said micro computer ratio controller comprise: a setting circuit, a edge line selecting circuit, a signal equalizing amplifier circuit, a positive and negative signal control circuit, a signal processing circuit, a manual auto-neutralizing circuit, a power amplifier circuit, a single chip controlling circuit, a display circuit. The input of the setting circuit is connected to the panel and is used for setting the control mode and outputting the driving signal to the single chip control circuit; the single chip control circuit receives the driving signal and outputs the indication signal to the edge line selecting circuit, signal equalizing amplifier circuit; positive and negative signal control circuit and manual auto-neutralizing circuit.

Description

technical field [0001] The invention relates to the precision control of coil materials, in particular to an intermediate correction and guidance system realized by applying sensor technology and single-chip microcomputer technology Background technique [0002] In the mechanical equipment of packaging, printing, textile, papermaking, plastics, printing and dyeing industries, in order to ensure the processing quality, improve productivity and reduce waste, it is necessary to perform intermediate correction and guidance on the coil. The intermediate correction and guidance system is mainly composed of a photoelectric sensor, a controller, and an actuator. The photoelectric sensor detects the position of the edge or the position of the marking line to pick up the position deviation signal, and then outputs the position deviation signal to the controller. The controller performs logic operations to generate The control signal is used to control the actuator to correct the devia...
