RNA explains how to maintain feeding equipment

Properly maintaining RNA Automation feeding equipment will give the user maximum value for money.

Equipment that is run on a 24/7 basis leaves little time for preventative maintenance.

Equipment should be inspected prior to beginning a production run.

If the equipment is new, the manual should always be read before operating the machine.

The utility services (voltage, compressed air and electrical equipment) should be checked before running the equipment, as ancillaries such as sufficient air-supply are often overlooked.

In the case of a bowl feeder, the internal lining should be clean and free of dust.

The operator should have a checklist available if possible and be familiar with the operating instructions supplied.

RNA supplies clear instructions with each feed system with pre-set parameters documented as a quick reference-guide.

OEM spare parts are available off the shelf, but spares should always be carried for unforeseen problems and users should be aware of fitting procedures.

If a problem occurs, off-the-shelf spare parts allow the user to schedule a replacement.

Mick Keane, technical director of RNA, has further advice on protecting and maintaining bowl feeding-systems.

'Machine cleaning is often a standard requirement in the pharmaceutical and food industries.

'In fact, all feeding systems will benefit from regular cleaning to improve the reliability and life-span.

'Debris and dust on the component tracks will greatly decrease the performance of the feeder; in this case, cleaning a feeder is essential at the start of a production run.

'RNA can provide simple dust covers or even full acoustic covers to protect the equipment.

'Check the bowl top is tightened down correctly and that the area surrounding the feeder is clean and tidy.

'Any cables should be fastened securely and away from edges of the machine.

'Spring packs and coils should be periodically checked; cracked or rusted spring-packs should be replaced immediately.

'Coils should be set at the correct factory tolerances as set out in the manual.

'RNA dive units are low amplitude and as a result have low noise characteristics: any increase in noise levels should be investigated immediately.

'Most special-purpose machines perform in different ways.

'Training helps the operator achieve maximum machine performance and take ownership of the equipment.

'To meet production goals and maximise equipment investment, operators should be involved at the beginning of the project, even at the concept of the system.

'Scheduling a maintenance plan focuses on setting-up core maintenance tasks and ensures the machine's performance.

'A maintenance plan can include routine inspection, testing and performance trials and cost analysis,' he added.
