Whether it's the front, middle or end of the line, HPT has the right system to ensure that you make the most of your capital equipment. HPT's front-of-line automated systems are some of the most advanced, reliable and cost-effective solutions in the world. We have extensive experience in destacking ferrous and non-ferrous metals of varied geometries for a range of press applications. We manufacture new and rebuild existing systems of all types and sizes.
Some of the styles of destacker that HPT specializes in:
Pogo Style: Programmable,
overhead array of vacuum cups mounted on independently or gang
fired pogo arms lift single sheets off of a stack until the
blank is stripped off onto an overhead magnetic or vacuum transfer
belt. The belt then feeds the blank into a blankwasher or directly
onto a gauging table.
Shuttle Style: Shuttle style
destackers consist of a programmable, overhead transfer being
either inline or perpendicular (T-configuration) to line flow
where the shuttle retrieves a blank from a fanning station and
deposits it onto a transfer conveyor to feed it forward to washing
and gauging stations. HPT's fastest shuttle destacker employs
a linear induction motor (LIM) that drives the shuttle carriage
and lifter head using magnetic field technology that was originally
developed in Europe to drive high-speed magnetically levitated
HPT is well versed in the design and manufacture of all of the critical modules of a sound destacking system, including:
Crane Saver: Heavy-duty
conveyors designed to precisely index large, full pallets of
Lift Tables: Heavy-duty
hydraulic lifts designed to incrementally index pallets as blanks
are depleted from a stack.
Sheet Fanners: Flexible
arrays of fanners that employ magnetics, forced air or other
means of separating and isolating a single blank from a stack
for easy, repeatable retrieval by a lifting head or robot.
Suction Lift or Lift Head:
An integral part of any destacker, which engages a blank staged
at a sheet fanning station and removed it for transport to the
next operation. Typically these heads are made up from a series
of vacuum cups.
Continuous Run Forks: A
series of tines, much like those on an eating utensil that it's
named after, the fork. These tines are spaced to fit into the
lifting holes (slots) on a pallet, normally reserved for the
forks on a lift-truck. The tines hold the stack of steel so
that the pallet can be lowered and removed and a new, full pallet
put in place underneath, allowing a continuous run of blanks.
Gauge Station: Just prior
to the blank being loaded into the press, a gauge station positions
the blank to ensure that it's properly loaded into the forming
die. HPT makes use of traditional gauging methods as well as
advanced magnetic positioning that is free of contact from end-stops
and side crowders. The gauge station also, sometimes incorporates
a transfer conveyor prior to the positioning station that allows
for the queuing of blanks.
Reject Station: An infrequently
used station to capture blanks determined to be 'rejects' through
a manual intervention or in the rare event of a double-blank
