Abstract

The feeding device comprises a horizontal circular singling disc, which rotates continuously or intermittently and has a peripheral crown of recesses acting as article receiving pockets. The surface of the singling disc is subdivided into a first, larger article-receiving portion acting as feed reservoir for the articles which are fed at random thereinto, delimited by a fixed circumferential side wall extending over a circumferential arc around the periphery of the singling disc, and by a fixed partition wall extending across the surface of the singling disc, and into a second smaller article-delivery portion lying outside of the feed reservoir. At the interior of the feed reservoir there is mounted a distributor dish having the shape of an asymmetrical flat or truncated cone. The distributor dish is cased to perform rotary oscillations parallel to the surface of the singling disc, about an axis which coincides with the axis of rotation of the singling disc. In this manner, the articles fed into the feed reservoir are gently stirred so as to prevent clogging and to permit easy accommodation in the respective receiving pockets.

Dependent claims

A device for feeding articles in orderly succession for further processing, comprising

(a) a horizontally disposed, circular disc having a crown of recesses spaced along its circumference for receiving said articles;
(b) means for rotating said disc;
(c) the surface of said disc being subdivided into
(i) a larger receiving portion acting as a feed reservoir completely enclosed by a fixedcircumferential side wall extending along the periphery of said disc, and a fixed partition wall extending across the interior of said disc;
and
(ii) a smaller delivery portion located outside of said feed reservoir;
(d) a distributor dish of generally conical shape which covers a portion of said receiving portion and has an arcuate circumferential portion adjacent to the inner periphery of said crown of recesses, said distributor dish presenting, in top plan view, the approximate shape of a sector with rounded corners, the arc of said sector being concentric with the rotation axis of said disc and extending close to the inner periphery of said crown of recesses, and the radial edge of said sector located upstream in the direction of rotation of said disc being curved in a convex manner, while the radial edge of said sector located downstream in the direction of rotation of said disc is curved in a concave manner;
and
(e) means for driving said distributor dish in a rotary oscillating path in a plane parallel to the surface of said disc about a vertical axis;
(f) whereby said articles fed into said feed reservoir are agitated sufficiently to prevent clogging of said reservoir and to facilitate their orderly reception in said recesses.
