Tension control system






 






(1)     The menu function enables storage and reading of 4 types of operation data.






(2)     The optional memory cassette enables reading of operation data and writing of data in the other STC-858A tension controller.






(3)     The controller has a weak excitation function for powder clutch / powder brake.






This function will improve the torque rising operation in low-speed operation mode or during the initial start-up of machine.

Semi-automatic tension control system, STC-858B tension controller





STC858B tension controller is a full digital tension controller with high precision and multi-function which to match up  tension detector to form a closed-loop tension controller system an then receives the signal from LS series tension detector after intelligent PID operation processing  internally, regulating implementing structure and to auto  matically control the tension of the long material at the unwinder, feed reel, and winder.







STC858B tension controller uses a new graphical LCD display which Chinese and English display clearer and  then generates a control voltage of 0 to 24V DC to control the powder clutch/brake and the hysteresis clutch/brake, or generates the torque command voltage of 0 to 10V to send to the servo amplifier.


















Features







Using 32-bit high speed CPU, Graphical LCD display, with human interface design which is very easy to operation.





Support thickness accumulation (need one proximity switch or encoder, need input thickness of material)





Speed ratio method (need two proximity switch or encoder, no need input thickness of the material)





Supports ultrasonic detectors (no settings are required after calibration of the detector)Two reel exchange.





Double 24V/4A input, can directly drive two brake/clutch





Can output 0-10V, 4-20mA drive inverter/servo motor.





Easy installation and commissioning, the tension calibration process is simple.





Support standard Modbus communication protocol, all parameters are open, and it is very convenient to connect PLC/touch screen.





Parameters protection by password, avoid inadvertent modification

Sunrise Group LOAD CELL









FUNCTION





Sunrise Group the load cells used for web tension control. The inner ring in the form of a bi-directional strip ensures centered mounting of the ball bearing. The radial forces created by the web unbalance the strain gauges linked together to form a measuring bridge on the inner ring. This leads to an analog output signal proportional to the web tension.







AREA OF USE





Sunrise Group the load cells can be used for web tension control in practically all processing plants where web-type materials are processed or finished. In front of processing stations, in particular, it is of fundamental importance that the web is transported with a continuous web tension.







FEATURE





1. Low hysteresis

2. Temperature compensation

3. Full-bridge strain n resistance

4. Excellent linearity and stability

5. Apply to idler roller and live round roller detecting

6. With maximum overloading to 500% of rated loading











APPLICATION





With a 90¡ã horizontal-vertical wrapping angle on the measuring roller and a horizontal measuring direction, optimum web tension measurement is assured. Only detection of the bearing forces on both sides by the tension sensor can prevent incorrect measurements caused by the web moving sideways and asymmetrical web tension distribution.
