Description
How it works
The recirculating accumulation table is a mass flow buffer that keeps the line running through short downstream stops. Two chain fields run in opposite directions under a loop of angled guide rails. Containers either cross the table and leave, or turn at the diverter and circulate until the line takes them again.
Normal production
When the line downstream runs normally, containers travel straight across the table from infeed to outfeed. The table adds nothing to the flow.
Recirculation
When downstream capacity is full or the outfeed gate closes, the diverter guides containers into the loop. They circulate around the table in an oval path and accumulate without back line pressure and without stopping. Upstream equipment keeps running until table is full.
Single filing
At the outfeed the containers are brought back into single file and handed to the next conveyor. A motorised roller at the outfeed reduces the risk of jamming on containers that need it.
Configurator price includes
-> Table assembly AISI304
-> Low friction plastic chains
-> Gear motors
-> Assembly and test run at our workshop
Not included
-> Motorised roller at the outfeed. It reduces the risk of jamming and is not needed for every container.
-> Pneumatic outfeed closing system.
-> Custom 1+1 infeed and outfeed modules to match an existing line.
-> Motor wiring, sensors and control. We can add a control panel to your order on request.
-> Installation on site unless agreed otherwise.
Information required for quotation
The configurator above covers width and length. To quote the actual figure we also need the following.
-> Container type, diameter, height and weight, and whether it is full or empty.
-> Line speed in containers per minute.
-> Required buffer capacity, in containers or in minutes of line output.
-> Available floor space and infeed height
Typical applications
- Buffering empty or filled bottles or cans before packing or downstream handling
- Buffer between process equipment and packaging equipment to allow changeover time
Build options
| Size | Width up to 3000 mm. Max lenght depends on the load carried |

Characteristics
Strengths
- Simple and reliable design
- Infeed can be on any side. This allows for better placement in room
Limitations
- Outfeed single filing speed is limited
- Not suitable for products with high center of gravity that can tip easily
- The centre chains wear unevenly, because they carry recirculating product more of the time.
