Article counting and stacking apparatus

Claim 2

Article handling apparatus comprising in combination means for delivering a column of articles to a discharge point, a wheel for transporting articles to a conveyor, said wheel having means for holding articles thereto and being positioned with the outer surface thereof at said discharge point, a pick off wheel of smaller diameter than said transporting wheel for removing articles from said delivery means and positioning them on said transporting wheel, means for driving said wheels such that said pick off wheel is rotated in the same direction as said transporting wheel, said pick off wheel being positioned with the axis of rotation thereof passing through said transporting wheel between said discharge point and the axis of rotation of said transporting wheel, said pick off wheel being substantially tangent to said transporting wheel at said discharge point.

Claim 3

Apparatus according to claim 1 wherein said transporting and pick off wheels are positioned in side by side relationship.

Claim 4

Apparatus according to claim 2 wherein said pick off wheel is rotated faster than said transporting wheel.

Claim 5

Apparatus according to claim 2 wherein said article holding means are vacuum ports in the outer surface of said transporting wheel.

Claim 6

Apparatus according to claim 3 wherein said pick wheel is formed with a set of spaced teeth arranged in discontinuous manner around its periphery so as to transfer articles to said transporting wheel in clearly defined groups.

Claim 7

Apparatus according to claim 5 wherein the second through last tooth is equally spaced from the preceeding tooth and the first tooth is spaced a substantially larger distance from the preceeding last tooth of the set.

Claim 8

Apparatus according to claim 3 wherein said transporting wheel is driven by a tubular shaft and has a ring gear mounted thereto, a stationary shaft extends through said tubular shaft, an arm extends from said stationary shaft adjacent said ring gear, said pick off wheel is pivotally mounted on said arm, and a gear mounted to said pick off wheel engages said ring gear to drive said pick off wheel.

Claim 9

Apparatus according to claim 7 wherein a pair of transporting wheels are positioned on each side of said pick off wheel and mounted on aligned tubular shafts, a stationary shaft extends through each of said tubular shafts, said inner ends of said stationary shafts being interconnected by a crank member for accomodating said pick off wheel, and a pair of gears mounted to said pick off wheel on a common shaft and engaging each of said ring gears, one of said transporting wheels being driven by its tubular shaft and the other transporting wheel being driven through said ring gears and said gears mounted on said pick off wheel.

Claim 10

Apparatus according to claim 1, including a horizontal conveyor extending beneath said transporting wheel to receive a first layer of articles therefrom, a second transporting wheel spaced from said first transporting wheel along said conveyor, a second means for delivering a column of articles to a discharge point adjacent to the outer surface of said second transporting wheel a second pick off wheel for removing articles from said second feed means and depositing them on said second transporting wheel, said second transporting wheel being positioned at least two article thickness above said conveyor and being synchronized with said first transporting wheel to stack a second layer of articles on the first layer of articles.

Claim 11

Apparatus according to claim 9 wherein both of said transporting wheels are provided with vacuum ports in their outer surfaces to hold articles thereto, said pick off wheels are formed with a set of spaced teeth arranged in discontinuous manner around their periphery so as to transfer articles to said transporting wheels in clearly defined groups and to form stacks of clearly defined groups of articles upon said conveyor.

Claim 12

Article handling apparatus comprising in combination means for delivering a column of articles to a discharge point, a wheel for transporting articles to a conveyor, said wheel having means for holding articles thereto and being positioned with the outer surface thereof adjacent to said discharge point, a pick off wheel of smaller diameter than said transporting wheel for removing articles from said delivery means and depositing them on said transporting wheel, means for driving said wheels such that said pick off wheel is rotated in the same direction as said transporting wheel, said pick off wheel being positioned with the axis of rotation thereof between said discharge point and the axis of rotation of said transporting wheel, a horizontal conveyor extending beneath said transporting wheel to receive a first layer of articles therefrom, a second transporting wheel spaced from said first transporting wheel along said conveyor, a second means for delivering a column of articles from said second feed means and depositing them on said second transporting wheel, said second transporting wheel being positioned at least two article thickness above said conveyor and being synchronized with said first transporting wheel to stack a second layer of articles on the first layer of articles.

Claim 13

Article handling apparatus comprising in combination means for delivering a column of articles to a discharge point, a wheel for transporting articles to a conveyor, said wheel having means for holding articles thereto and being positioned with the outer surface thereof adjacent to said discharge point, a pick off wheel of smaller diameter than said transporting wheel for removing articles from said delivery means and depositing them on said transporting wheel, means for driving said wheels such that said pick off wheel is rotated in the same direction as said transporting wheel, said pick off wheel being positioned with the axis of rotation thereof between said discharge point and the axis of rotation of said transporting wheel, a horizontal conveyor extending beneath said transporting wheel to receive a first layer of articles therefrom, a second transporting wheel spaced from said first transporting wheel along said conveyor, a second means for delivering a column of articles from said second feed means and depositing them on said second transporting wheel, said second transporting wheel being positioned at least two article thickness above said conveyor and being synchronized with said first transporting wheel to stack a second layer of articles on the first layer of articles.

Claim 14

Apparatus according to claim 11 wherein both of said transporting wheels are provided with vacuum ports in their outer surfaces to hold articles thereto, said pick off wheels are formed with a set of spaced teeth arranged in discontinuous manner around their periphery so as to transfer articles to said transporting wheels in clearly defined groups and to form stacks of clearly defined groups of articles upon said conveyor.
