This Slant Disc Feeder was designed to feed a plastic medical part. The customer required a low-speed rate of 5 parts a minute and an affordable, cost-effective solution.
Space constraints contributed to the design challenges of this machine.
A vibratory system might have been a first choice feeding solution for this low part rate application. However, the bottle size would have increased the footprint of the machine outside the space allotted.
The vertical design of the system created a space-saving layout and the use of the Slant Disc Feeder rather than the vibratory feeder, reduced noise in the production environment. Simple controls logic was used, and no PLC was required.
Bulk product was supplied from an elevating prefeeder into a slant disc feeder bowl on the demand of a bowl level sensor which monitored the level of the product in the system.
Stainless steel construction with FDA compliant materials
Product was carried in pockets on the outside diameter of the disc and misoriented product was rejected back into the feeder bowl.
Properly oriented product was carried out of the bowl and into a gravity track into a star wheel mechanism which transferred the product to the customer’ s assembly equipment.
Product oriented for the customer’s receiving equipment.
