Deviation detection of bag making machine

Bag Making Machine is a machine for making various kinds of plastic bags or other material bags. Its processing range is plastic bags of different sizes, thicknesses and specifications, with plastic bags as the main products. However, deviation may occur in use. Let's take a look at it
In the process of material transportation, due to uneven force, uneven thickness, traction roller roundness and other reasons, the horizontal position deviation may occur, so the on-line deviation detection should be carried out in time.
In the early stage, the speed of Bag making machine was not high, and the material deviation was adjusted by the operator according to the actual field observation.
The photoelectric sensor has the advantages of simple structure, stable performance, high precision, fast response, etc. now the photoelectric sensor is used to track the boundary of different color areas on the edge of packaging materials, read out the offset between the actual position of the strip and the set position, convert the offset into electrical signal, amplify, compare, calculate and analyze, and then send the command to the servo controller to control the motor Drive the guiding mechanism to return the strip to the set position to achieve the purpose of automatic tracking and adjustment.
