Tray handling.
To
avoid
tray
shaking
and
excessive
deceleration and acceleration of the product
inside the tray, the handling is extremely
smooth and accurate.
Trays are moved from the smart belt to the
sealing station through moving arms, which are
gripping the group from the side. These arms
are controlled by a servomotor system, whose
main characteristics are smoothness, high speed,
consistency, accuracy and extremely low
maintenance and by a long-stroke pneumatic
piston for the rotation to allow a very good
smoothness and a wide range of settings.
Film unwinding and waste rewind.
Film saving and reliable continuous run are at
the base of the development of the system
incorporated in this tray sealer. The reel is
positioned on a cantilever shaft which is
connected to a servomotor. Film is kept in
tension through several shafts, which are
supported both sides to avoid any misalignment.
A dancing bar keeps a constant tension on the
film during the unwinding.
The film is pulled through the tool via two
counter rotary rollers, controlled by an electrical
motor, which allows smooth pulling to reach the
maximum waste savings. A clutch controls the
tension on the continuous running film waste
rewind.
