Light Duty Variable Pressure Live Roller Accumulator Conveyor, Roach Model 138VP

Roach Model 138VP accumulates goods safely with a 2-1/2% minimum backpressure. The basic design eliminates complicated adjustments.

Minimum pressure conveyors are typically comprised of a belt-driven roller conveyor with some type of adjustment to allow the drive of rollers to be increased or reduced. Belt-driven roller conveyors with knurled thumb spring adjustability lower and raises the belt driving against the rollers carrying the product. This ensures that when the product is driven together at the end of the line, the pressure of the upstream boxes does not crush the first carton to reach the end.

Features

• Safe transports of goods
• Transports loads up to 100 lbs per foot
• Simplest method ever devised for accumulating cartons, boxes, etc.
• Reversible
• Packages of uniform weight can be accumulated temporarily using pneumatic package stops

Applications

• Used to transport and accumulate cartons or unit loads so that they are efficiently queued and fed into sorting, wrapping, palletizing, strapping or various other processes
• Manufacturing
• Distribution
