Three Installation Methods For The Photoelectric Switch Of The Guding Machine

The web guding machine is a professional correcting device for the bag cutting machine and the printing machine. It is based on the electric eye tracking transmission signal to the web controller. The controller then outputs the correcting signal to the stepping motor at the bottom of the guiding  machine. The motor drives the screw at the bottom of the machine to move. The effect of correcting the deviation is achieved! The following describes the three installation methods of the photoelectric switch of the web guiding machine.
Three installation methods of the photoelectric switch of the guide machine: 1. Double switch single side control. The photocell is placed on one side of the material. The edge of the material is placed in the insensitive area of the photosensor. Advantages: The control error is small, and the position of the photoelectric head can be unchanged when the material width changes.

2. Single switch single side control. When the single-sided single-switch control is performed, the photo-electric head is placed on one side of the material. The edge of the material is placed under the photosensor spot. Advantages: The control error is small, the debugging is simple; when the material width changes, the position of the photoelectric head can be unchanged.

Disadvantages: If the edge is damaged, the tracking will force the material to tear. When the material is finished, the actuator will run to the limit position; without the balance point, the motor will rotate continuously.

3. Double switch bilateral control. Two photoelectric switches are placed on both sides of the material to keep the two photo heads in the same state. Advantages: If the edge of the material is broken, or the material is finished, it will not affect the operation. Disadvantages: Photoelectric corrector manufacturers believe that if the material width changes frequently, it is necessary to change the position of the photoelectric head frequently. If the distance between the optical axes of the two photoelectric heads is different from the material width, a correction error will occur.
