Abstract
A coin sorter in which a sorting head is positioned over a rotating pliable disc and wherein coins are sorted by the combination of an inwardly or outwardly extending tapered edge and a series of pins generally positioned in an outwardly extending line spaced from the tapered edge. The spacing between the line of pins and tapered edge changes with radial dimension, whereby coins of different diameter are urged over the tapered edge by pins at different positions. The coins are then captured between the head and pliable disc and rotated to exit positions which are unique for each coin about the outside of the sorting head.
Claims10
In a coin sorter for sorting coins of a multiplicity of diameters having a plate including a side closely facing a rotating, generally planar, resilient disc, said plate having an opening through which coins are loaded onto said disc and defining an interior edge thereof, said plate having an outer edge forming boundaries of said plate, and said side of said plate being configured with lands and recesses which vary in shape and vary in clearance from said disc, the improvement comprising:
- one of said lands of said plate having an elongated edge in a region between said edges of said plate, said elongated edge extending through differing radaii and differing angular positions with respect to rotation of a radial line about the center of rotation of said disc, and at least a substantial length of said elongated edge being an inclined edge which is inclined generally toward, and in the direction of, rotation of said disc;
- a plurality of coin deflection regions, discrete ones of said regions being differently spaced from said inclined edge as a function of the difference in diameters of coins to be sorted, whereby a coin of a discrete diameter is rotated by said disc and moved to a position where it is engaged between one of said deflection regions and said inclined edge and is thereby urged by said rotating disc across said inclined edge and thereby captured by said one of said lands and at a discrete radial position which differs for coins of different diameters;
- and
- said outer edge of said plate having portions varying in distance from the center of rotation of said disc and selectively cooperating with the radius of the paths of rotation of said coins of a multiplicity of diameters;
- whereby coins of different diameters are discharged from said sorter at different positions along said outer edge of said plate.
