——The correction light curtain adopts the principle of infrared light blocking, and the purpose of correcting the strip is
achieved by automatically controlling the correction device for the amount of light blocking of the strip. ——LC correction light curtain is divided into three categories: precision correction, online correction, and online centering. Each system includes a pair of high-resolution light curtains and two signal cables
——Output mode: RS485 communication, analog quantity, switch quantity.
Correction light curtain detection.
Mode 1: Single set of unilateral detection - polarization correction light curtain: a set of
polarization correction light curtain detects one cluster edge to realize the correction effect.
Mode 2: Two sets of unilateral detection-polarization correction light curtains: a set of polarization correction light curtains are used on both sides to detect the two cluster edges at the same time, and each outputs corresponding signals to realize the correction effect.
Mode 3: Single set of bilateral detection - centering light curtain: use a set of correction light curtain to detect two cluster edges at the same time, the detection position of the light curtain is only valid at both ends, and the detection of the middle part is invalid
(that is, the blind area) and outputs the same one signal to achieve deviation correction effect. ——LC series polarization
correction light curtain is specially applied to corrugated paper equipment, the main function is to prevent the paper from
deviating Real-time correction can greatly reduce the deviation of waste in the production process.
