From Dorner Conveyors
The Alpine Conveyor is a compact spiral configuration commonly used as an accumulation or elevating buffer zone between machines or as a process step for cooling or drying. It can also be used for line balancing or product changeover purposes.
Alpines can be configured as an elevating/ lowering system with a single or double serpentine configuration. Uses include an in-line accumulator with entry and exit at different levels, or an in-line or off-line accumulator with entry and exit at the same level.
Direction is determined by the product, belt selection, and product rate.
In-Line vs. Off-Line:
If an Alpine is to be used as a buffer, it needs to be determined if in-line or off-line is desired. If in-line is used, all normal production flow goes through the Alpine and would be accumulated upon a storage signal.
Typically, a stop device is required. Off-line has traffic flow around the Alpine and diverts into accumulation as needed.
