How To Operate The Special Electric Eye Of Photoelectric Guide System?

Today's correction system manufacturers tell you how to operate the photoelectric sensor for photoelectric correction system?

Because the photoelectric switch is set, the detection distance meets the requirements. According to the wrapping paper you are using, refer to the light source selection guide table below, determine the light source to switch on and off (take green as an example), and then decide whether the output mode is bright or dark based on the needs of your photoelectric correction system. Finally, adjust the sensitivity according to the following three steps (the output is activated in the following way, the packaging is marked with light colors and the back is dark).

 (1) Move the wrapping paper so that the light spot falls on the back area behind the mark. Turn the sensitivity backwards to the end, and then slowly rotate it clockwise until the indicator just turns on. Remember the position of the potentiometer at this time (point A).

 (2) Move the wrapping paper so that the light spot falls in the center of the mark. At this time, the indicator light is on, and then slowly turn the adjustment knob counterclockwise until the indicator light just goes out. Remember the position of the twist at this time (point B ).

 (3) After completing the above two steps correctly, twist the potentiometer to the middle C position of the two points A and B, and the adjustment is completed. The larger the distance between the two points A and B, the larger the color difference is, and the more stable the detection is. However, there must be at least one grid distance between points A and B, otherwise the detection will be unstable.

The high-precision MYJP series cardboard polarizing light curtain is suitable for high-precision detection and measurement. Including precision correction, online correction, online similar detection and measurement. The improvement of the control accuracy of the cardboard to the light curtain greatly reduces the trimming margin of the cardboard and improves the input and output rate of the paper material.

Cardboard centering light curtain (cardboard polarizing light curtain) principle:

It includes at least two sets of detection mechanisms, programmable controllers, and deviation correction motors on the base paper rack, which are respectively installed to detect the horizontal position and offset of the paper material. Under the control of the controller, the paper material is detected for the horizontal position and offset, and the data of the detected horizontal position and offset is transmitted to the programmable controller, and the programmable controller detects the detected horizontal position and offset. After the amount is compared and calculated, the control correction instruction is output to the correction motor, and the horizontal position of the paper material is moved to align the paper material vertically.

The main detection methods of the series of cardboard light guides are:

1. Single set of unilateral detection-polarizing light curtain

2. Two sets of unilateral detection-polarizing light curtain

3. Single set of bilateral detection-centering light curtain.
