The Problem...
Disposal of the Stiff Scrap Matrix
Carton Master of the Midwest, Inc., planned to install a new narrow-web
folding carton press to produce a large volume of small folding cartons
at their plant in Hamilton, Ohio. The roll-fed press is specifically
designed for printing and diecutting high-quality, short-run folding
carton jobs. The primary responsibility of the press operator is to
maintain product quality. Disposal of the stiff scrap matrix needed
to be virtually automatic and as noiseless as possible, to allow the
operator to concentrate on the press, not on scrap removal.
The Solution...
A Pneumatic Scrap Handling System
A
pneumatic scrap handling system, was installed that tool the 16 3/4"
wide scrap matrix directly from the press, cut it into pieces so that
it could easily be conveyed and baled. The conveying air is filtered
and returned back into the plant. The heart of the system is a BloApCo
Model 5SC Trim Cutter "rail-mounted" with a BloApCo Model 25-4 Material
Handling Fan and located in a pit directly in line with the press discharge.
The scrap matrix is drawn directly into a rectangular pick-up duct,
through a silencer, into a trim cutter and fan, to a cyclone mounted
above a closed door baler. Uniform scrap pieces produced by the BloApCo
trim cutter yield denser bales, saving haulage costs. The conveying
air is returned to the plant through two large filter bags for an energy-efficient
system.
Because the scrap
handling system is installed below floor level, the press operator does
not have to be concerned with scrap disposal, the noise level is reduced,
and the area is clear, simplifying general access and maintenance.
