Position Detection of Bags on a Conveyor Belt with Retro-Reflex Sensors

For the distribution of small objects such as bags on conveyor belts, it is necessary to detect their position along the entire conveyor belt width in the direction of transport. This is the only way to ensure that the speed of the belt can be adjusted and the objects conveyed correctly to the next station. To this end, several retro-reflex sensors with focused laser light, which do not influence each other, are mounted above the conveyor belt between two belts. The reflectors are located in the gap between the belts. All switching signals are collected via connection boxes and further processed via a control system.

Universal Retro-Reflex Sensors

Universal retro-reflex sensors are suitable for the detection of glossy, chrome-plated or reflective surfaces thanks to the polarization filter. They work with red light or laser light. Objects are detected by interrupting the light beam between the sensor and the reflector.
