Safe protective system for color sorter

Abstract

The invention discloses a safe protective system for a color sorter. The system comprises a main controller, an electric controller, a photoelectric switch, a current sensor, an indicator light, a voice prompting module and a thyristor module, wherein the photoelectric switch is mounted at a closing side of a safe protective door of the color sorter; the current sensor and the thyristor module arecorrespondingly connected to a power supply loop of the color sorter; signal output ends of the photoelectric switch and the current sensor are correspondingly connected to a signal input end of themain controller; a signal output end of the main controller is correspondingly connected to the signal input end of the electric controller, the indicator light and the voice prompting module; the signal output end of the electric controller is connected to a controlled end of the thyristor module. With the adoption of the system, the closing state of the safe protective door can be automaticallydetected; in case that the safe protective door is not closed normally, a light alarming signal and a voice alarming signal are immediately sent, and the power supplying loop is timely cut off, so that the color sorter can be stopped, and as a result, the potential risk is avoided.

Description

technical field [0001] The invention relates to the field of color sorters, in particular to a safety protection system for a color sorter. Background technique [0002] The color sorter is a device that uses photoelectric detection technology to automatically sort out the different-color particles in the granular material according to the difference in the optical characteristics of the material. At present, color sorters are widely used in the fields of bulk materials or packaging industrial products, food quality testing and grading. [0003] Before the color sorter is turned on, the operator usually needs to check whether the safety protection door is closed normally. The color sorter can only be turned on after confirming that the safety protection door is normally closed. However, due to subjective forgetting and human judgment errors, when the safety protection door is not closed normally , Operators often turn on the color sorter, or even forcibly turn on the color ...

[0003] Before the color sorter is turned on, the operator usually needs to check whether the safety protection door is closed normally. The color sorter can only be turned on after confirming that the safety protection door is normally closed. However, due to subjective forgetting and human judgment errors, when the safety protection door is not closed normally , operators often turn on the color sorter, or even forcibly turn on the color sorter, thus causing safety hazards
