Abstract

A vibratory feeding system includes a hopper, a tray and a vibrator. The hopper is disposed above the tray so that components can flow from the hopper to the tray. The vibrator is mounted to the tray, so that the tray can be vibrated to move components along the tray. The tray can have a v-groove along which the plurality of components can flow. The tray can also have a plurality of sections that are separated by steps. The plurality of components flow down the steps as they move along the tray. The vibration, the v-groove and the steps cause the components to be singulated as they flow along the tray. A plurality of shedders can be mounted to the tray to create a path through which the components flow. The shedders can regulate the flow of components from the hopper and/or assist in singulating the components.
