Recycling centre 'baled out' by CSL
August 1st 2010 Conveyor system increases throughput
and reduces reliance on lift trucks
One of UK's fastest-growing waste management companies
specialising in recycling waste paper collection and
processing, recently appointed Conveyor Systems to
design and install a handling system to transport and reject
under/oversized large bales of paper prior to entering a stretch
hooding machine.
Premier quality paper material is collected and sorted at the
MRF, baled and film wrapped to protect the content for shipping
back to recycling. CSL installed two heavy duty powered roller
conveyors to transport compressed loads of paper from two
balers operating
adjacently,
positioned at either
side of a dividing
wall. The new
conveyors were
mounted onto
existing loadcell
weighing platforms
and an ink-jet
system printed the
registered weight onto the side
of the bale.
A 90 degree triple chain
transfer diverts and combines
the flow of bales onto a main
feed conveyor that is
interfaced with the stretch
hooder and an inverter turns
the loads 180 degrees. At this
point, the bale size and weight
is automatically checked prior
to entering the film wrapping
machine and any over or
undersized bales are removed
by forklift to be returned for
recycling. Conveyor Systems
provided the mechanical and
electrical installation,
including building of the
control panels and PLC. A light curtain provides a safety zone
around the stretch hooder for protective access and
maintenance.
After the bales have been checked for accuracy of dimensions
and weight, they pass through the stretch hooder to be film
wrapped and come to an end stop on the conveyor. Once a second
bale butts to the first, the two bales are removed for shipping by a
forklift clamp that is less susceptible to damaging the outer film.
A spokesperson for the customer said: "The system has been
handling 1.5m long bales weighing 1200kg and at speeds of one
bale per 30 seconds. It increased efficiencies in throughput and
reduced forklift activity
considerably." More articles from Conveyor Systems Limited: |
