Abstract
Abstract A conveyor system for conveying planar panels in single file. The conveyor system can be used for receiving panels from bulk storage to a workstation. The conveyor system includes a conveyor belt apparatus located to receive the panels at its upstream end from the bulk supply device. A panel turning device is located at the downstream discharge end of the conveyor device for receiving the panels from the conveying device and redirecting them into the inlet end of a chute. An accumulative device is located over the conveyor to maintain a steady supply of panels to the chute. A photo cell control at the chute controls the number of spacers stacked in end-to-end relationship in the chute.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
173 words
A conveyor system for conveying planar panels comprising: a conveyor belt apparatus having a top flight upon which the planar panels rest and are conveyed; accumulator means located along the top belt flight in brushing contact with the planar panels on the top belt flight; a vertical panel receiving chute located proximate the downstream end of the conveyor belt apparatus; and, panel turning means located between the downstream end of the conveyor belt apparatus and inlet end of the chute for receiving panels from the conveyor belt apparatus and redirecting them downwardly into the inlet end of the chute comprising: a brush wheel located between the downstream end of the conveyor belt apparatus and the inlet end of the vertical chute; and, an endless belt apparatus having one flight which extends over a portion of the top conveyor belt flight at the downstream end of the conveyor belt apparatus, curves around a portion of the perimeter of the brush wheel, and extends downwardly a distance to the inlet end of the vertical chute.
Claim 2
Dependent Claim
173 words
A conveyor system for conveying planar panels comprising: a conveyor belt apparatus having a top flight upon which the planar panels rest and are conveyed; accumulator means located along the top belt flight in brushing contact with the planar panels on the top belt flight; a vertical panel receiving chute located proximate the downstream end of the conveyor belt apparatus; and, panel turning means located between the downstream end of the conveyor belt apparatus and inlet end of the chute for receiving panels from the conveyor belt apparatus and redirecting them downwardly into the inlet end of the chute comprising: a brush wheel located between the downstream end of the conveyor belt apparatus and the inlet end of the vertical chute; and, an endless belt apparatus having one flight which extends over a portion of the top conveyor belt flight at the downstream end of the conveyor belt apparatus, curves around a portion of the perimeter of the brush wheel, and extends downwardly a distance to the inlet end of the vertical chute.
Claim 3
Dependent Claim
90 words
The conveyor system of claim 1, further comprising: control means at the vertical chute and operatively associated with the conveyor belt apparatus and endless belt apparatus of the panel turning means for deactivating first the endless belt apparatus and then a period of time later deactivating the conveyor belt apparatus when the level of panels in the chute is at a first preselected position, and for reactivating the conveyor belt apparatus and endless belt apparatus of the turning means when the level of panels drops below a second preselected position.
Claim 4
Dependent Claim
42 words
The conveyor system of claim 1, wherein the accumulator means comprises a brush disposed over the top belt flight with the bristles depending toward the top belt flight a sufficient distance to make contact with the panels on the top belt flight.
