High Speed Centrifugal Feed System for Medical Product
Featuring a vertical elevating prefeeder and high speed gravity roller tracks, this centrifugal feed system was developed to feed and orient medical product in excess of 800 ppm and built to run 24/7 in a continuous production environment, while using the smallest footprint possible and preserving the integrity of the parts being fed.
The vertical elevating prefeeder reduced the floorspace requirement, allowed an operator to load product at an ergonomic level and metered the product into a centrifugal feeder.
A level sensor in the bowl signaled the pre-feeder to turn off when bowl was full of product.
The centrifugal bowl feeder pre-oriented product in an end to end, at random fashion using various mechanical sweeps and air jets.
The parts discharged from the centrifugal bowl feeder to high speed gravity roller tracks which performed the final orientation of the product.
Oriented product was qualified as various sensors controlled the speed of the system, allowing the feeder to speed up or slow down based on the queue level of the product.
Glass fiber sensor array on gravity rollers monitored part level in the track to prevent parts from backing up into the bowl.
The discharge track held a queue of oriented parts for presentation to the customer’s assembly system.
Video Demonstration
This short video demonstrates a vertical elevating prefeeder and high speed gravity roller tracks, this centrifugal feed system was developed to feed and orient medical product in excess of 800 ppm and built to run 24/7 in a continuous production environment, while using the smallest footprint possible and preserving the integrity of the parts being fed. The vertical elevating prefeeder allowed an operator to load product at an ergonomic level and metered the product into a centrifugal feeder, which separated and singulated the product into a random front to back pre-orientation and discharged them into precision orienting gage rollers which performed the final orientation of the product and carried it to the customer’s downstream application.
