Abstract
Abstract A conveyor structure of the roller type includes an alignment device for maintaining relatively flat objects in aligned positions with respect to each other. The device includes a plurality of second rollers disposed between the rollers of the conveyor, the second rollers being eccentrically rotatable about axes extending longitudinally or perpendicular to the axis of the first rollers. The second rollers move upwardly between the first rollers to engage the flat underneath surface of articles traveling on the conveyer to lift them up and to move them laterally into engagement with a positive stop position to one side of the conveyer, whereby the objects are then relatively aligned with respect to each other.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
169 words
A conveyor including a frame having horizontally spaced longitudinally extending frame members, a plurality of longitudinally spaced conveying roller members journalled on said frame members about generally horizontal and transversely extending axes and defining a conveying surface adapted to support the lower sides of objects carried thereupon, means for maintaining said objects in alignment on said conveyor comprising shifting means being extendable above said conveying surface for shifting the objects axially of said rollers above said conveying surface, and aligning means comprising a support along one side of said frame and a plurality of guide rollers rotatably mounted on the support on substantially vertical axes, said plurality of rollers projecting below the plane of said conveying surface to define a generally vertical aligning surface positionable to substantially intersect said conveying surface along the path of movement of said objects for supported sequential aligning engagement of each of the objects, thereby essentially obviating obstructive jamming of the objects by said aligning means as the objects move along the conveying surface.
Claim 2
Dependent Claim
169 words
A conveyor including a frame having horizontally spaced longitudinally extending frame members, a plurality of longitudinally spaced conveying roller members journalled on said frame members about generally horizontal and transversely extending axes and defining a conveying surface adapted to support the lower sides of objects carried thereupon, means for maintaining said objects in alignment on said conveyor comprising shifting means being extendable above said conveying surface for shifting the objects axially of said rollers above said conveying surface, and aligning means comprising a support along one side of said frame and a plurality of guide rollers rotatably mounted on the support on substantially vertical axes, said plurality of rollers projecting below the plane of said conveying surface to define a generally vertical aligning surface positionable to substantially intersect said conveying surface along the path of movement of said objects for supported sequential aligning engagement of each of the objects, thereby essentially obviating obstructive jamming of the objects by said aligning means as the objects move along the conveying surface.
Claim 3
Dependent Claim
23 words
The invention according to claim 1, and means mounting said aligning means and positioning said aligning means translationally axially of said conveying rollers.
Claim 4
Dependent Claim
27 words
The invention according to claim 2, and said mounting means comprising means for angularly positioning said aligning means about one of a plurality of spaced vertical axes.
Claim 5
Dependent Claim
16 words
The invention according to claim 3, and said vertical axes being spaced longitudinally along said conveyor.
Claim 6
Dependent Claim
16 words
The invention according to claim 3, and said vertical axes being spaced laterally of said conveyor.
Claim 7
Dependent Claim
30 words
The invention according to claim 2, and said mounting means including slotted fastener means releasably securing said alignment means in its respective positions for angulating and translating said alignment means.
Claim 8
Dependent Claim
150 words
A conveyor including a frame having horizontally spaced longitudinally extending frame members, a plurality of longitudinally spaced conveying roller members journalled on said frame members about generally horizontal and transversely extending axes and defining a conveying surface adapted to support the lower sides of objects carried thereupon, means for maintaining said objects in alignment on said conveyor comprising, means for shifting the objects axially of said rollers above said conveying surface, aligning means comprising a support along one side of said frame and a plurality of guide rollers rotatably mounted on the support on substantially vertical axes and projecting below the plane of said conveying surface along the path of movement of said objects for sequential engagement by each of the objects, and said shifting means comprising a cylindrical hub and a tire formed of a material of softer quality that will reduce wear on the objects to be conveyed.
Claim 9
Dependent Claim
150 words
