Accumulator
Inverter
Motor with encoder
The rotation speed of the motor with
encoder can be changed easily and flexibly
by the inverter according to the commands
sent from a programmable controller or the
winding diameter calculation unit.
Programmable controller
The programmable controller is used for
administration of the winding/unwinding con-
trol of the material, data collection, inverter
operation command transmission, parameter
change, and other operations.
Reference shaft
AC servo
The torque/speed control function of the
AC servo enables stable line speed control.
Tension detector
The tension detector is used with the
full-automatic tension controller or a ten-
sion meter to calculate the tension signal.
Powder clutch
Torque is controlled for unwinding the material
according to the tension controller output.
Operation/display
Unwinding section
Tension controller
Using the material tension measured by
the tension detector, a constant tension
is kept for winding by automatic control.
Human-machine interface (HMI)
The HMI units are used to operate the
connected devices, visualize the line
condition, or indicate the faults.
Winding diameter calculation unit
Highly accurate winding diameter calcu-
lation is performed, which enables the
control of the taper tension or the slip
rotation speed of the powder clutch.
