The Fosber Terminal Stacker System provides the most versatile combination
of stacking possibilities. The Terminal is designed to stack sheets at high
speeds and full height stacks, bundles or a combination of both. Modular
design of the support structure allows for complete lay-out flexibility
and for ease of installation. The electrical and pneumatic requirements
for wiring, piping and cable ducts are integrated into the design of the
support structure. Even the support structure for each individual delivery
belt is of modular design. The PVC belts all have an integrated V-profile
on the underside located on each side of the belt. The V-profiles run in
anti-skew grooves which physically prevent any lateral movement of the belts
even during phases of acceleration. Each stacker outlet is fitted with three
or more belts with individual PLC commanded speed control. The Terminal
stacker has three main sections: The Braking Section - is composed of a
series of brushes which apply adjustable pressure on the sheets. This slows
down and shingles the sheets exiting the cut-off knife. The applied pressure
and number of brushes activated are automatically controlled according to
the type of production. The Separation Section - separates the stream of
shingled sheets, corresponding to end of stack or end of order. Precise
separation is accomplished via a fixed or moving clamp system, which guarantees
separation even in cases of severe warp or coated (slippery) sheets. At
separation the lower interrupt bar raises while the upper lowers; thus,
holding back the first sheet of the new stack or order. The old stack (or
order) is then gently accelerated away. The Stacking Section - consists
of an upper expulsion roll group, a motorized conveyor elevator deck and
a motorized self-positioning backstop with encoder control. The elevator
deck is gently and linearly lowered via a DC motor , which allows sheet
by sheet descent, keeping a constant angle of the sheet onto the stack.
The features of the Terminal stacker combine to provide excellent presentation
of the finished stack. |
