Linear Vibratory Feeder

The device is for the feeding of small magnetic cores to a test station. The device feeds a broad sheet of cores to the test point, assures an ample supply, and eliminates the need for grooves or other discontinuities.

In drawings A and B, feed tray 1 and return tray 2 are inclined with opposite slopes and connected by chutes so that a recirculating path is provided. Tray 1 is suspended on leaf springs 3 and 4 and tray 2 is suspended on springs 5 and 6. Both trays are connected by flexure springs 7 and 8 to single moving coil actuator 9. An AC in a moving coil is tuned to the resonant frequency of the system to maintain the vibration of .001'' to .002'' amplitude. The suspension springs are inclined from the vertical as in conventional vibratory feeders to provide a vertical as well as a horizontal vibration which feeds objects on trays incrementally.

When a quantity of cores is placed in either tray, the vibrating action tends to spread them into a single layer which moves uphill incrementally. In tray 1, a stream of cores flows to and around the periphery of a pickup device 10 such as the vacuum disk, where cores can be picked for testing. Surplus cores proceed by way of deflector 11 and chute 12 to neighboring tray 2. Here the core stream is raised to deflector 13 and chute 14 to be returned to tray 1 for another pass around the pickup station.
