Sheet Winding Device (Winding Section) Case Study of Prevention of Sheet Damage and Sagging by Automatic Adjustment Of Tension
Issue
Preventing Sheet Sagging and Damage (Winding Section)
Conventional Equipment
Winding process for sheet manufacturing equipment using an induction motor.
- Application
- Winding of packaging sheets, tapes, films, and paper rolls
Conventional Problems
- The increase in winding diameter causes changes in the load and winding speed, which resulted in sagging and damage to the sheet
- Wanting to install a tension controller and torque detector, but unable to do so due the high costs
Solution
Torque Motor TM Series
Optimal Motor Characteristics for Winding, Enabling Automatic Winding at the Proper Tension
Equipped with the characteristics required for winding, the TM Series allows the sheet to be wound at the proper tension from start to finish without sustaining damage.
Specific Application Examples
No Need to Adjust Torque During Winding
Torque motors feature sloping characteristics, with low torque at high speed and high torque at low speed. They move quickly at the beginning of winding when the load is light, and can produce a good amount of torque at low speed near the end of the winding process when the load is larger.
Achieves Low-Cost System Configuration
The list price of the TM Series (Torque Motor and Power Controller) ranges from 19,300 JPY~34,400 JPY.
More cost-effective than using tension controllers and torque detectors.
Easy Torque Setting with Dedicated Power Controller
One of the components, the power controller, is used in torque setting.
3 setting methods can be selected: Internal Torque Potentiometer, External Torque Potentiometer, and DC Voltage Control.
