Flexible Feeder with Recirculating Conveyor for Medical Vial
Jump to: System Specifications || Quote Request Form
This Flexible Feeding solution was designed to feed double and singly wrapped medical vials for robotic selection at 100 parts per minute.

Performance Feeders’ Vertical Prefeeding Elevator, with a Lexan cover to reduce particulate, housed a bulk supply of both styles of vials.

The unoriented vials were transferred from the prefeeding elevator onto a belt conveyor for robot inspection. Vials not selected by the robot were dropped onto a second cleated belt conveyor and returned them to the hopper to recirculate.
The Performance Feeders Controls team wired the system for a low-level bin sensor to detect a low bulk parts supply and a stack light to alert machine operators of the need for additional parts in the hopper. This simple and economical flexible feeding system was built for seamless integration.
