Abstract

In a delivery device small parts (15) in the nature of studs, bushes, pins and suchlike are conducted by means of a perpendicularly displaceable strut (6) into a transportation channel (11) from a sloping collection area (1). The strut (6) slides along a retaining and dividing wall (3) and has an upper narrow side 6a which slopes obliquely downwards towards the retaining and dividing wall (3). Owing to the obliquely downwards directed slope of the upper narrow side (6a) the small parts (15) become reliably lodged on the retaining and dividing wall (3) when the strut (6) is located in its lower operating position (FIG. 2). In the upper operating position the small parts (15) slide obliquely downwards over the retaining and dividing wall (3) into the transportation channel (11). A metering plate (7) with projections and gaps, located on the strut (6) in its upper region, determines how many small parts (15) are to be conducted into the transportation channel (11) each time the strut (6) is lifted. The transportation channel (11) has a compound receiver profile, for example, a segment of a circle (13) starting from the upper side, out of which a rectangle (14) protrudes downwards. In …
