Document Type and Number:
Japanese Patent JP2000501174
Kind Code:
A
Abstract:
One or more concentric rings of component seats are rotatable about the rings' center. The seats are uniformly angularly spaced and the rings are incrementally rotated, the increment of rotation being the angular space between adjacent seats. The rings are inclined at an angle and a stream of components is poured onto the rings as they are rotating. Stationary fences adjacent to outboard sides of the seats, confine unseated components to tumble randomly, due to gravity, over empty seats passing through arcs of the rings' rotation paths. The random tumbling results in seated components. In the paths of the rotating rings are electrical contactors for coupling the components to a tester. Preferably there are five contactor stations to permit five different kinds of tests to be performed simultaneously. Tested components pass beneath an ejection manifold which defines a plurality of ejection holes which register with a set of seats each time the ring is rotated an increment. Ejection tubes are coupled to the ejection holes. The components are ejected from their seats by blasts of air from selectively actuated, respective pneumatic valves. Due to the blast of air and gravity, the ejected components travel down the tubes and are directed into sorting bins according to a tube routing plate. The stream of components can be selectively directed to each fence in response to a signal from a detector indicating that the fence is deprived of components. Sensors detect seated components that were not ejected by the ejection manifold.
