COSAW combines the simplicity of wheel and belt
conveyor designs into a zero pressure accumulator. As
one of the very first zero pressure conveyor designs,
this former Unex product provides proven reliability and
durability for a variety of applications for any product
conveyable on skate wheel. Its mechanical linkage makes
installation simple and easy to maintain.
The 4' wide V-bottom belt eliminates shortcomings
associated with belt tracking and allows lengths up to
200 feet. Product weights up to 75 pounds per foot
moving at speeds up to 300 hundred feet per minute are
possible. Our standard unit features axle reinforcing
channels that prevent axle deflection making it ideally
suited for impact loading applications, such as high
speed pick lines. In addition, the standard wheel
capacity has been upgraded to 100 pounds each. The drive
allows for varying power requirements up to 2 horsepower
and more belt pull than many competitors.

|How the accumulation works
The 4' belt is supported by pressure wheels every
12". When the weight of a conveyed item causes the
sensing wheels to depress, two sets of pressure wheels
are lowered, disengaging the belt from the items in the
zone behind it.
When Box A rests on Sensing Wheel #1 (SW1), both sets
of Pressure Wheels #1 (PW1) will lower. Box C will then
come to a stop, depressing SW2, eliminating drive over
PW2 and causing Box D to stop.
When the case stop is lowered, Boxes A and B will
resume travel. When Box B clears Sensing Wheel #1, the
belt will re-engage Box C which will also resume travel.
When Box C clears Sensing Wheel #2, Box D will re-start.
This creates a 'singularity action' into accumulation
and when resuming transportation.
