Description
How it works
The bi-directional accumulation table is a mass flow buffer that sits alongside the main line. When downstream equipment stops or slows, such as during a labeller roll change or a filler adjustment, containers back up on the line. A fill sensor detects the backup and starts the table chain, which moves away from the line and draws containers onto the table. Once capacity returns, the chain reverses and returns the containers to the line in a controlled flow.
Normal production
During normal operation, products pass by on the main line and the table stays empty. The table only takes product when the line backs up, so it adds no disruption to the regular flow.
Loading and unloading
-> When the line fills, containers are pushed across the table infeed and the chain carries them away from the line. The table fills gradually across its full surface.
-> When downstream capacity becomes available, the chain reverses and returns containers to the line at a controlled rate.
Fill level sensors on the guide rails tell the control system when to load, hold or unload.

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
- Buffer empty or filled cans and bottles before packing or downstream handling.
- Buffer between process equipment and packaging equipment to allow changeover time
Build options
| Width and length | Width up to 3000 mm. Max lenght depends on the load carried |
|---|---|
| Frame material options | Frame AISI 304 as standard, painted steel or AISI 316 on request. |
| Guide rails | Guide rails and fill level sensors to suit the container. |

| Food-grade option | Sanitary package with NSF H1 registered oil and washdown surface protection as an option. |
Characteristics
Strengths
- Simple and reliable design
- Large buffer capacity in a compact footprint
Limitations
- First in, last out. The last containers loaded are the first returned, so it does not suit processes that need strict batch order.
