<p>An apparatus for the oriented feeding out of caps provided with pull-zones usually comprises a disc which can rotate at high speed, onto the plane working surface of which the caps are dropped. By the rotation of the disc the caps are moved to the periphery of the disc where they are made to slide along a stationary wall. Through the movement over the disc and the contact with the wall the caps are oriented, and correctly oriented caps are removed subsequently by means of guide plates via an opening in the wall, to be conveyed further to a capping machine. The collection of the caps by means of the guide plates and the feeding out through the limiting opening in the wall, however, sometimes causes deformations which prevent the feeding out. The apparatus in accordance with the invention has instead of the wall provided with openings a guide rail in the form of a continuous ring which is arranged at such a distance above the surface of the disc that the cap is allowed partly to slide in under the guide rail. However, the lug on the cap prevents the cap from passing wholly under the guide rail. At a point along the periphery a radially movable feeding out element is provided which engages with the passing caps and withdraws them via the space between the disc and the guide rail, with a short-time deformation of the pull-lug.</p> |
