Noise in the workplace is becoming an increasingly important issue these days and it is hard to avoid the constant advertisements from compensation lawyers seeking clients for hearing loss claims.
Vibratory feeders have a reputation for being noisy, but at RNA our feeders include a number of features to mitigate against this problem.
Our drive units offer high performance, but with minimal referred vibration and so low noise levels; most of the time avoiding the need for costly and bulky enclosure, although there can be supplied for particularly noisy parts.
Our coating department can provide special finishes and acoustic coatings to reduce noise. Polyamide bowls and rotating centres can provide similar benefits.
The RNA range of drive units are also available in CSA/UL approved versions, we are the only European manufacturer to offer this as a standard option.
RNA polyamide bowls have low friction and can be specially machined to customer’s specifications and are easily reproduced. They also have a low noise level.
Rotating Centres (SRL) are used: 1. to relieve pressure on the bowl drive unit 2. to keep vibration of components to a minimum 3. to reduce noise level.
Coating minimises wear and tear, reduces noise and damage to components. Coatings can be selected according to the application.
Sound Cover reduces noise and protects against dust and contamination.
Where RNA really excel at is supplying its standard drive units as a tooled system, a typical system comprises of a vibratory bowl feeder and linear feeder combined with a mechanical part separation at the end of the linear system. The Control of Noise at Work Regulations 2005 (the Noise Regulations) came into force for all industry sectors in Great Britain on 6 April 2006.
