Ryson Vertical Accumulation Buffer

The Ryson Vertical Accumulation Buffer is an efficient use of overhead space.

Overhead space is efficiently used for overhead dynamic storage or buffering while preserving valuable floor space.

The Ryson Vertical Accumulation Buffers utilize one reversible spiral or combine two or more spirals for up and down movement. Most conveyable products can be handled, including bottles, cans, pails, bags, bundles, totes, containers and wrapped or unwrapped items.

The accumulation buffers build on the already proven Ryson Spiral technology featuring low maintenance and long life. The buffers are available with 8”, 12” 16”, 20” or 24” wide slats and can be delivered in powder coated, stainless steel or washdown versions.

Dynamic Buffering

The Ryson Accumulation Buffers can be used to provide dynamic storage where products need time for cooling, drying or curing. Additional dynamic buffer storage capacity can be obtained by adding pairs of spirals.

The Ryson Accumulation Buffers can also be used to take up surges between manufacturing processes and can provide dynamic buffering during shorter production or packaging line interruptions. This will reduce downtime and increase productivity. Some products can be merged back into the production or packaging lines directly from the accumulation buffer while others will need additional merging devices – depending on type of product and speed of operation.

Robotic Buffer System

The Ryson Spiral Conveyor can be used in conjunction with a robotic pick and place module for dynamic buffering.

Modular Design

Ryson Vertical Accumulation BufferAn innovative modular design allows Ryson to customize with ease and modify in the field to accommodate emerging needs. All spirals are made to order and are available in 4 basic configurations ( A, B, C and D), accommodating most requirements relating to the location of the in and out feed tangents. All configurations can operate up or down in a clockwise or counterclockwise rotation and custom configurations are available. Call us with your specific needs.


Most of our spirals are shipped without controls because they are normally integrated into an overall conveyor control system. The spirals always include an inverter duty gear motor and two proximity sensors, one for the automatic chain tensioner and the other for the overload protection device.

A Variable Frequency Drive (VFD) is required for the proper operation of the spiral. Ryson offers several controls options including :

  • Stand alone control panel with interface capabilities
  • Prewired motor disconnect
  • Proximity sensors prewired to a central junction box
  • Prewired missing slat detection sensors.
