13 Claims, 8 Drawing Figures PATENTEDumHm SHEET 2 [1F 5 PATENTEDHAR 2 71973 SHEET 30F 5 APPARATUS FOR SORTING PARTICULATE ARTICLES CROSS REFERENCES TO RELATED APPLICATIONS A continuation-in-part of applicants earlier filed application, Ser. No. 135,225, filed Apr. I9, 1971, now U.S. Pat. No. 3,669,260, and entitled dMETHOD OF SORTING PARTICULATE ARTICLES.
BACKGROUND OF THE INVENTION 1. Field of the Invention Increasing attention is being given to apparatus for sorting particulate matter such as coins, shells, pills, and the like. Recent inventors have evolved a plurality of rotating devices which centrifugally discharge articles to be counted from the edges of the rotating plane. Traditionally, centrifugally discharge d articles are forced through a stationary exit aperture and thence counted, as they are tangentially ejected. A primary shortcoming of utilizing stationary exit apertures is the tendency of such devices to become jammed with the article, necessitating shutdown for clearing of the aperture in order to continue counting.
2. Description of the Prior Art SUMMARY OF THE INVENTION According to applicantsAutheville suggests inclining the rotating discs so as to affect a measure of control. However, his discharge gates are stationary and, it is submitted, subject to jamming.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a vertical sectional view ofa proposed form of the apparatus showing a feeding hopper mounted upon a rotating inner disc, adjacent with the outer rotating top gauging ring and outer rotating lower support ring;
FIG. 2 is a top plan thereof;
FIG. 3 is a fragmentary vertical section of a modified gauging ring which has curvate apertures in the lower surface of its vertical wall, configured as the cross-section of the articles being counter;
FIG. 4 is a fragmentary perspective, slightly enlarged, showing the feeding of round articles such as pills through the curvate apertures in the gauging ring;
FIG. 5 is a fragmentary vertical section of a modified method of counting, wherein the top gauging ring and lower support ring discs are rotated simultaneously by means of a single peripheral belt;
FIG. 6 is a top plan thereof;
FIG. 7 is a fragmentary transverse section of a modified and concave rotating inner plate; and
FIG. 8 is a fragmentary transverse section of a modified and convex rotating inner plate. Y
DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1 there is illustrated a device for counting particulate articles according to the present method and including a baseplate 10 and an intermediate plate 12 secured to each other by a plurality of threaded bolts 14, 16, 18 and 20 having suitable washer'and nut elements. The entire assembly may be angled or tilted with respect to the vertical as an assistance in sorting by adjustment of baseplate 10 with respect to these threaded bolts.
Inner rotating discharge plate 44 is mounted upon hub 45 which is seated in bearings 62, 64, 66, 68 and driven rotatably by means of belt 50. An outer support ring 36 is supported upon rotating cradle 38, which is driven by means of belt 40 at a speed identical to the rate of rotation of discharge plate 44 or variant therewith. Gauging ring 34 is supported above outer discharge ring 36 by means of a plurality of drive pulleys 24 including groove 32, engaging the edge 33 of gauging ring 34. Pulley 24 is driven by the belt 30 and may be supported upon shaft 28 having bearings 28 and 70. The belt 30 may be used to drive pulley 24 at speeds consistent with belt 40 and 50 or at variance therewith, according to the gravitational characteristics or configuration of the articles being counted. As illustrated in FIG. 1, there is a stationary outer baffle 72, supported upon base 74, resting upon plate 12, and extending vertically so as to overlap aperture 42 defined between top gauging ring 34 and support or discharge plate 36.
As illustrated in FIG. 2, plate 72 includes at one side tangential slot 82 defined by outer edge 86 and rounded inner shoulder 84. As will be apparent, articles centrifugally discharged through aperture 42 are thrown through slot 82 which may be horizontal, alternatively inclined downwardly or upwardly (as illustrated in phantom in FIG. 5) adjacent a photocell or similar counting device 83-85.
In FIGS. 3 and 4 there is illustrated variant gauging ring having curvate apertures 88 in the lower face of the inner wall of the gauging ring. Round'articles, such as pills 9 0 are admitted through the apertures 88, only as they are aligned in the desired vertical position,
which may be the position selected for counting by ture only when they are on their sides conversely, arti- I cle 92 is not centrifugally discharged, since it is vertically upright. As will be apparent, the height off the gauging ring with respect to the outer support ring in all modifications of the invention may be varied by adjustment of plate 12 upon thread bolts 14, 16, 18 and 20.
In FIG. 7 a modified inner plate 104 with a concave profile is illustrated and in FIG. 8 there is illustrated a further modification wherein inner plate 106 has a convex profile.
