Accumulation Conveyor


Accumulation conveyors allow cases to queue up on a conveyor in between processes. It has become as ubiquitous to conveyor systems as belt conveyors. Without the ability to accumulate containers from process to process the entire system could only move as fast as its slowest process.

Accumulation conveyors are typically driven by chain or a small belt but can also be driven by a 24v roller. In the case of the first 2 the dive mechanism runs continuously, and photo eye sensors actuate an air bladder to raise or lover the drive train to connect with the rollers. The 24v style accumulation conveyor the drive roller turns on and off to stop a single case in a zone.

Accumulation conveyors can be zero contact or zone to zone contact. With both options the sensors look upstream of the zone being controlled. If a product is in this zone the (meaning the current zone cannot move forward) the drive apparatus drops out and allows the case to stay in the zone, while still allowing the rest conveyor behind it to run. This allows a queueing of the conveyor until such time as a process downstream accepts the product on the conveyor and the cases move forward.

Why an Accumulation Conveyor Makes Sense for your Operation

Accumulation is a requirement for almost any conveyor system. Cases need to queue up prior to a merge, sorter, or routing into a put away or picking process. Without accumulation conveyor the throughput of all systems would be greatly reduced. They decouple the processes downstream from the upstream and allows both to process as efficiently as possible.


Accumulation conveyors have some of the following features:

  • Photo eye accumulation senses product
  • Solenoids control troll to air mechanisms
  • 9 dia. rollers carry product
  • Varying speeds a release logic types


Operations benefit from Accumulation conveyor by providing the operations the following:

  • Buffers product in between processes
  • De-couples processes allowing each to be efficient
  • Queues up product to merge lines together
  • Creates High Throughput rates by bunching product together


Accumulation conveyor works in any application. The hardware can be configured for small or large parcels, corrugate or bags, and for low or high sortation throughput.

  • Zone routing systems
  • Batch based pick-to-put system
  • Sortation systems
  • E-commerce pack out systems

Why Work with Conveyco

Conveyco has been applying conveyor to order fulfillment systems for over 40 years. Our engineering department can apply Accumulation conveyor correctly to minimize capital expense while keeping the system functioning as needed. Accumulation conveyor systems are often an afterthought, but our engineering team understand the importance of doing things correctly, and the pain that is caused by improper design. Conveyco has spent decades building relationships with the best in breed conveyor lines to allow a wide array of tools curated to pick the manufacturers that best fit each application. There is a fine line between minimizing costs without giving away functionality. Each situation is different, and Conveyco knows where conveyor capital is best spent, and where the opportunities for value engineering exist.
