Ball ejection equipment with ball infeed

摘要

The equipment consists of a frame (12) in the shape of a truncated pyramid. The top of the frame has four sides on which the four sides (24) of a basket, for the balls, can be hinged together. The underside of the basket incorporates a guide (28) which feeds balls, one at a time, to a ball ejector mechanism (14,18). The ball ejector mechanism consists of a cylinder in which a pneumatically operated plunger is driven against a ball which is supported on a ring (20) at the top of the cylinder. The cylinder is mounted on a pivot (16) so that the angle, at which the balls are ejected, can be adjusted. The sides of the basket for the balls can be swung down to cover the ejector mechanism.
