Photoelectric Sensor In Logistics

Project Description:

Photoelectric Sensor Has Been Widely Used In The Logistics Transmission Line

As an indispensable “sense” in the automation equipment, the photoelectric sensor has been widely used in the logistics transmission line and plays an important role in judging the size of the workpiece, checking the stacking height, controlling the liquid level, counting the products, checking the quality, cutting the fixed length, checking the small materials and so on.


Photoelectric sensor has been widely used in the detection of materials. For example, on a machine tool automatic processing line, materials are transported on a feeding line, and diffuse reflection or counter-emission photoelectric sensor is fixed at the outlet side of the feeding line. When materials enter the detection area, they block the beam from the transmitter and trigger the switch, feedback to the control system a signal, so as to
give the manipulator a feeding instruction, manipulator to perform feeding action.

  1. Application of Dimension Inspection

The reflection plate type sensor calculates the pulse duration of the material box in its detection area to judge the length of the box.

  1. Application of material stacking height detection

The height of a layer of material is detected by setting the corresponding height of each layer of material on both sides of the transmission line. A plurality of photoelectric sensors are superposed and placed in turn, and the detection distance can reach several meters.

  1. Application of liquid level control

A diffuse reflection photoelectric sensor with optical fiber is installed on both sides of the beverage transmission line as a counter to detect the liquid level in the transparent bottle body. If there is no liquid at the height of the sensor set, the switch will not be triggered.

  1. Application of product count and quality inspection

In the sensor with a counter so that the photoelectric sensor has a counting function, such as the number of paper detection, through the logistics line of the number of beer detection.
