In the process of material transmission, due to various reasons such as uneven force, uneven thickness, roundness of traction roller and so on, the position deviation in the horizontal direction may appear, so the online deviation detection should be carried out in time.
At the early stage, the speed of bag-making machine was not high, and the material deviation was manually adjusted by the operator according to the actual observation on the spot.
Because the photoelectric sensor has simple structure, reliable performance, high precision and fast response, we use photoelectric sensor edge different color area dividing line of packaging material tracking, readout strip actual location and setting the position offset, the offset is converted to electrical signal amplification and to compare, after operation and analysis, Send instructions to the servo controller to control the motor drive correction guide mechanism, the strip will be returned to the set position, to achieve the purpose of automatic transmission tracking adjustment.
