Mitsubishi Electric FA products
Roll to roll application
Coater/laminator
Mitsubishi Electric offers a line-up of optimum products for each manufacturing process.
When the inverter is used along with other suitable Mitsubishi products, efficient and highly reliable control can be performed for more large-scale facilities.
Unwinding section
The unwinding shaft rotation speed is con-
trolled to keep the dancer roll position con-
stant, by which in turn a constant film tension
is maintained. Also, the unwinding shaft can
be changed without stopping the line.
Feeding section
The feeding section feeds the workpiece at
a constant speed using feedback from the
36
tension sensor.

Reference shaft
The reference shaft determines the line
speed from the measured value of the
dancer roll position. It also sends commands
to each section.
Accumulator
By installing the accumulator in the pro-
cessing line, the reserve portion of the ma-
terial can be temporarily accumulated, and
the roll on the winding shaft can be replaced
without stopping the unwinding shaft.
Feeding section
Winding section
High precision torque control is enabled by
using feedback from the tension sensor.
Tension change due to mechanical loss
can be prevented. Even if the film feed
speed increases or decreases, the tension
applied to the film is maintained constant.
By adjusting the tension on the workpiece,
it is possible to avoid imperfections such
as wrinkles or deformation caused by the
increase in winding diameter.
