Technical Documentation G.Mondini S.p.A. Tray Sealer TRAVE-350
3
Sealing Station.
Once the trays are positioned in the sealing tool,
the lower part is raised and the sealing process
starts. High sealing force and consistency of
sealing parameters are critical to guarantee the
same seal characteristics tray after tray. The
TRAVE-350 is equipped with a high duty system
which is of an electromechanical type. A rod-crank
system is controlling the motion up and down of
the sealing tool, keeping an absolute control of the
tool position while still very fast. The sealing force
can reach 2200 Kg. Main characteristics of this
solution are smoothness, high speed, very high
consistency in sealing force, very high accuracy in
positioning and extremely low maintenance.
Tooling.
Each tray foot print has its own tool, but different
tray heights are handled in the same tool.
The construction is completely in anodised
aluminium and all parts are machined from a single
piece to reach the best accuracy in sealing pressure
distribution. Each tray cavity supports the base of
the sealing edge with a T section gasket to recover
from different thickness in the packaging material.
The location of the tray is as accurate as possible,
due to tray size consistency, to reach the best
results in seal location and film trimming. Sealing
plates are made of aluminium-bronze, to keep the
sealing temperature consistent in all contact points,
the sealing profile varies according to the specific
packaging material, it also contributes to remove
contamination from the sealing area. Heating is
provided by an element cast into aluminium. This
solution provides a long lasting heater plate and a
very accurate sealing temperature control: plus or
minus five degrees between each point.
Out feed.
A policord belt takes the sealed trays out of the
guarding in a straight line.
