Abstract
The invention provides a coil gathering station coil length measuring system based on distance measuring sensors. The system comprises a coil loading car and signal reflection boards located on the two sides of the car respectively. One side of the coil loading car is provided with a movable arm, and the other side of the coil loading car is provided with a fixed arm. The first distance measuring sensor is installed at the position of a movable shaft of the bottom of the movable arm. The measuring direction of the first distance measuring sensor faces the fixed arm. A second distance measuring sensor is installed at the position, on one side of the movable arm, of the coil loading car. The measuring direction of the second distance measuring sensor is opposite to that of the first distance measuring sensor. An existing encoder and four proximity switches are omitted for controlling the coil loading car. When the movable arm of the coil loading car carrying coils is completely opened and the movable arm is at the initial position, the distance between the movable arm and the fixed arm of the coil loading car is constant, and the length of the coil can be obtained by subtracting the distance obtained after the movable arm clamps the coil and walks from the constant distance.
