Abstract
Abstract A product conveying assembly for installation, for example, in a market check out stand receives products selected for purchase and brought by a customer in a buggy or cart and orderly end delivers them to a checker in the immediate location of a product code scanner, a key-in cost entry register, a scale, and/or bagging location. The customer places the products being purchased on a circular rotation product receiving and delivering belt, which has its central portions rotatably supported for rotation about a vertical support, rotatably mountable on a market check out stand. Over half but not all of this circular rotation product receiving and delivering belt is slidably guided on a support mountable on a check out stand. Further, this belt, beyond the slidable guiding support, is folded under as multi-directional rotational guides, such as omni wheels, are mounted on a shaft in turn mountable on a check out stand, to guide at least one side of this folding circular rotation product receiving and delivering belt, beyond the end delivery of a customer's products to a checker. Movement of this belt around the vertical support and over the omni wheels, occurs as a driving wheel assembly, mountable on the check out stand, rotatably bears against and rotates tangentially against the respective top and bottom peripheral surfaces of the folded under portion of the circular rotation product receiving and delivering belt.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
144 words
A conveyor assembly comprising a flexible disc shaped circular belt folded over under itself to form an upper product carrying run and a lower run, said upper run being substantially larger than said lower run and including the center of said circular belt, means confining said belt for rotation about a fixed vertical axis extending through said center, a stationary support underlying a substantial portion of said upper run, means drivingly engageable with said belt for imparting rotation to said belt about said axis, and guide means engageable along the folded portion of said belt connecting said upper and lower runs to maintain said belt in predetermined folded configuration during rotation thereof, said means confining said belt for rotation about said axis comprising a part secured to the upper run of the belt at the central region of said belt extending about said center.
Claim 2
Dependent Claim
144 words
A conveyor assembly comprising a flexible disc shaped circular belt folded over under itself to form an upper product carrying run and a lower run, said upper run being substantially larger than said lower run and including the center of said circular belt, means confining said belt for rotation about a fixed vertical axis extending through said center, a stationary support underlying a substantial portion of said upper run, means drivingly engageable with said belt for imparting rotation to said belt about said axis, and guide means engageable along the folded portion of said belt connecting said upper and lower runs to maintain said belt in predetermined folded configuration during rotation thereof, said means confining said belt for rotation about said axis comprising a part secured to the upper run of the belt at the central region of said belt extending about said center.
Claim 3
Dependent Claim
37 words
The conveyor assembly defined in claim 1 wherein said guide means is disposed only at one side of a plane containing said axis and extending at right angles with respect to said folded portion of the belt.
Claim 4
Dependent Claim
28 words
The conveyor assembly defined in claim 2 wherein said guide means comprises a set of omni rollers revolvable about a horizontal axis between said upper and lower runs.
Claim 5
Dependent Claim
81 words
The conveyor assembly defined in claim 2 wherein said guide means is disposed between said upper and lower runs and comprises a set of rollers and roller support means, said support means being mounted for rotation about a horizontal axis extending between said upper and lower runs, and said rollers being mounted on said support means for rotation about nonparallel axes which are spaced from said horizontal axis and which are contained in a common plane normally intersecting said horizontal axis.
Claim 6
Dependent Claim
37 words
The conveyor assembly defined in claim 2 wherein said guide means comprises a multidirectional roller assembly mounted between said upper and lower runs to engage the surface of said folded portion that faces toward said vertical axis.
Claim 7
Dependent Claim
98 words
The conveyor assembly defined in claim 1 wherein said guide means is disposed between said upper and lower runs and comprises a set of rollers and roller support means, said support means being mounted for rotation about a horizontal axis between said upper and lower runs, and said rollers being mounted on said support means for rotation about non-parallel axes which are non-intersecting with respect to said horizontal axis and which lie in a common plane normally intersecting said horizontal axis, said rollers being engageable with the surface of said folded portion that faces towards said vertical axis.
Claim 8
Dependent Claim
38 words
The conveyor assembly defined in claim 1 wherein said guide means comprises a set of omni rollers arranged between said upper and lower runs for engaging the surface of said folded portion that faces toward said vertical axis.
Claim 9
Dependent Claim
27 words
The conveyor assembly defined in claim 1 wherein said means imparting rotation to said belt comprises a rotatably-mounted, motor-driven member engaging the lower run of said belt.
Claim 10
Dependent Claim
35 words
The conveyor assembly defined in any one of the preceding claims 1-8 inclusive wherein said means drivingly engaging said belt is located at a position where it engages only the lower run of said belt.
Claim 11
Dependent Claim
27 words
The conveyor assembly defined in any one of the preceding claims 1-8 inclusive wherein said part is mounted on a shaft for rotation about said vertical axis.
Claim 12
Dependent Claim
45 words
The conveyor assembly defined in any one of the preceding claims 1-8 inclusive wherein said part is mounted on a shaft for rotation about said vertical axis and is disposed on the underside of said upper run to provide a support for said central region.
Claim 13
Dependent Claim
60 words
The conveyor assembly defined in any one of the preceding claims 2-5 inclusive wherein said means imparting rotation to said belt causes said upper run to revolve about said vertical axis in a pre-selected direction such that products carried on said upper run are discharged from the belt on the side of said plane where said guide means is located.
Claim 14
Dependent Claim
43 words
The conveyor assembly defined in claim 1 wherein said part is in the form of a plate mounted on a shaft for rotation about said vertical axis, said plate being positioned on the underside of said upper run to support said central region.
Claim 15
Dependent Claim
19 words
The conveyor assembly defined in claim 1 wherein said upper and lower runs are in parallel spaced apart relation.
