Linear feeders convey oriented components from bowl feeders over short or relatively long distances, thereby creating a buffer storage. They enable a consistent flow of orientated components from the bowl feeder to escapement devices creating product accumulation prior to a machine or handling unit.
Misorientated components are returned to prefeeders via a chute and vibration tray. In addition to horizontal conveying of components, linear feeders can be used to handle irregular supplies of parts from upstream equipment, creating a buffer store and smooth flow for further processes.
Sizes can be up to 3 metres long and are available to suit every possible application. RNA linear feeders share bowl feeder drive units multi magnet design, are robust, compact and virtually maintenance free.
Apart from pure transportation tasks, linear feeders also act as buffer and accumulation lines. Even if their feeding is incomplete or irregular, component parts can be continuously supplied by the preceding sorting installation for the following processing stage.
Besides, linear feeders enable a sorting free of lateral oscillation (linear sorting lines). These sorting lines can also be installed as multi-tracks, in order to achieve a higher sorting efficiency. Parts that have been sorted out are led back to the preceding feeding system via so-called sorting hoppers which are activated by the linear feeder as well.
Linear feeders also serve as a drive for bulk hoppers to stockpile mass-produced parts. Thanks to the way they are constructed, the advantage of these vibratory hoppers in comparison to other hopper systems is that they guarantee a trouble and gap-free material flow, plus they allow for large filling weights.
The linear feeders by RNA reach high feeding capacities and fulfil their tasks even on long feeding lines and under critical conditions.
