Accumulation Conveyors

When designing a conveyor system for your business, there will no doubt come a time when you decide you’ll need some sort of accumulation functionality. Thomas Conveyor & Equipment company is here to help! An accumulation conveyor can be used in a conveyor system prior to sortation, when merging product together, or at the end of the line where an operator will unload.

What sets an accumulation conveyor apart from other powered conveyors?

They assist in the control of the rate of flow of products through a production process. Rather than a continuous flow of products like other powered roller conveyors, the accumulation conveyor starts and stops the movement of loads automatically, allowing for storage and metering or batch advancing of loads. This is often achieved using accumulation zones, sensors, air valves and brakes.   The conveyor’s powered roller uses motorized rollers to drive the conveyors eliminating the need for drive belts, chains or line shafts.

There are a variety of designs and customizations to consider when designing your accumulation conveyor, including the amount of pressure (zero to variable pressure), and the size and weight of the materials being conveyed (light, medium, or heavy-duty). No matter your needs, Thomas Conveyor can work with you to design a system specific to your industry. Call us today to speak with an application engineer and view all of our accumulation conveyors below.

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

Light Duty Variable Pressure Live Roller Accumulation Conveyor which can transport up to 100 lbs. per foot with a  2-1/2% minimum backpressure. One of the simplest methods for accumulating cartons, boxes, etc., its basic design eliminates complicated adjustments found in other conveyor systems.

Medium Duty Variable Pressure Live Roller Accumulator Conveyor, Roach Model 196VP

Roach Model 196VP variable pressure accumulator conveys medium weight goods safely and with minimum backpressure. In a distribution or manufacturing operation, accumulation conveyors are commonly used to transport and accumulate cartons or unit loads so that they are efficiently queued up and fed into sorting, wrapping, palletizing, strapping or other processes.
