Chuck
Mandren opening and closing movement is performed with an hydraulic cylinder. Scissor mechanism is used up to 5 tons of roll weight, then cam mechanism is used. Works between 480 and 540 mm as standard. Diameters can be changed according to customer demand. Designed and manufactured in such a way that the deflection at the end of the mirror does not exceed 3 mm when the coil is loaded and centered.
Servo Driven Coil Side Supports
The servo motor controlled coil side support arms are moved by a hydraulic cylinder, such as the upper thrust arm and the rear support arm, and aligned with the coil.
It approaches the coil from both sides by means of screw shafts operating in the opposite direction.
A "side support unit" is provided as standard in the opener. The latter is priced as an option if desired.
Coil Car
The movement of the coil car towards the opener is provided by an electric motor placed in the car. Rack and pinion gear is used for position accuracy. The electric motor is driven by an inverter. It slows down as it approaches the target and allows it to be positioned in the correct position.
Caliper Disc Brake
The decoiler has a rotating disc mounted on the mandren. The amount of sagging of the opened sheet is continuously measured from the bottom. Decoiler speed and disc brakes are controlled by taking this precaution into account. This ensures that there is always enough material in front of the feeder
Control System
PLC & Motion Control : Siemens
• PLC: Siemens S7-1500 series
• HMI: Siemens KPT900
• Servo motor drivers: Siemens
• AC motor inverter: Sew, Siemens ABB or equivalent
Optional: Handwheel
The handwheel and drive servo motor are controlled manually and precisely.
Useful when the control panel is far from the press table and control is difficult in tool setting setups.
