Rubber Grommets / Vibration Dampeners

All vibratory bowl feeders have some sort of vibration dampeners below so that the vibrations are not transferred to the base on which the vibratory feeder is mounted. Vibratory feeders have to be bolted properly to the base so that they do not shift or move during working. Most vibratory bowl feeder manufacturers provide rubber grommets or rubber pads below the vibratory bowl feeders for isolating the vibrations from the base. However, most vibratory bowl feeder manufacturers use the rubber pads itself for providing mounting for the vibratory feeders. There is M6 / M 8 / M10 threading (depending upon the size) which can be used. However, the problem in this type of arrangement is that the bowl feeder has to be mounted from the bottom, relating to increased work for the operator / assembler. Secondly, as the rubber pads are exposed, there is the chance of oil / water / coolant seeping upto it and reducing their life. As against this, some vibratory part feeder manufacturers (like Elscint) provide a separate base plate after the rubber pads, which not only further isolate the vibration but also provides top mounting which is very easy to use. The rubber isolating parts are also enclosed inside the counter mass, providing them much needed protection so that their life increases.
