Tension Control, Edge Position Control, DC Motor Drive Expert Solution
“ High precision Edge Position Control System ” is to control material’s edge and let the edge position be the same position in the production process of material and is suitable for the edge position control of materials, which have neat edge and without burrs, such as thin films, papers and other materials.
The figure is the configuration diagram of Edge Position Control System in feeding process, the figure shows that the edge position of material is detected by an edge position detector with high-sensitivity, high-resolution, sending edge error detection signal to digital edge position controller, after signal processing, output driving signal to drive device (An electric cylinder showed in the figure), which moves the material’s frame, and achieve the purpose of edge position control of materials.
【 Video 】 Operation of Edge Position Control System ：
To demonstrate the application of Edge Position Control system in plastic inflation machine; It makes the edge position of the plastic bag be unchanged in the transportation process and the reel of finished product is flat and solid.
The performance introduction of Edge Position Control System ：
Edge Position Control System could monitor and control textile or plastic machine, which is producing strip-like object, for keeping edge in correct position and the whole roll of product is ordered and solid when winding is completed.. The Application of web Edge Position Control System :
Edge Position Controller is used for controlling the edge position of material in the process of Unwinding, Central Guiding, and Rewinding, the following Figure is the figure of assemble and installation of Edge Position Controller in the Unwinding system, it explains and shows that the edge position of material is detected by Photoelectric Sensor, generating a position-tolerance signal, and it is passed to Edge Position Controller for processing, after computing, Edge Position Controller sends a driving signal to a drive unit (this example is hydraulic cylinder), which moves the frame of feeding unit, then getting the purpose of Edge Position Control of material.
