Sound Control from actiOn feed systems...

A vibratory feed system can be the source of noise that distracts and disrupts employee concentration and generally has a negative effect on the work environment. The folllowing types of sound control are currently the most popular ways to make improvements.

Sound Enclosure

Usually sheet metal, lexan or plexiglass with structural support surrounds the equipment. The interior is covered with a sound-absorbing foam. Several panels are designed for access to the equipment inside the enclosure.

Sound Cap

An area currently being developed by actiOn feed systems is placing a partial cap over the top and sides of the feeder. Testing reveals that the majority of the sound waves eminating from the feed bowl rise straight up and out from the tooling areas.

Sound Cap & access cover

The sound cap addresses this source of noise while allowing much greater access to bowl for necessary routine maintenance or any service required. This is accomodated by simply lifting the cap off its stands (for smaller applications), or raising the top assembly support brackets (on larger caps). We estimate that sound can be reduced by from 5-20 decibels using this method along with an appropriate coating.

Double Bottoms

Another sound reduction tool is the double bottom. There are two levels welded into the bottom of the bowl and the air space is filled with sand, tar or other sound deadening material. If the bowl is ‘skirted’ (an angled piece welded in under the track, usually used to help prevent part jams between tracks), this can be capped and filled as well, offering a greater measure of noise reduction as the parts travel up the track.

Coatings

Coatings can also help reduce overall noise levels. Click here for more coatings information.
