Abstract
A curved belt conveyor having a generally planar ring shaped belt supported and guided for movement along a closed path of travel having first and second generally parallel, spaced apart runs with an inner peripheral edge of the belt substantially defining an arc of the circle about a predetermined center. In accordance with the present invention, the inner peripheral edge of the belt is engaged by a plurality of guide rollers, each of which is mounted for individual independent movement radially of the arc described by the inner peripheral edge. The rollers are resiliently biased radially outwardly against the edge of the belt.
Claims5
In a curved conveyor having a generally planar ring shaped belt, and means for supporting the belt and for guiding the belt along a closed path of travel having first and second generally parallel, spaced apart runs with an inner peripheral edge of the belt substantially defining an arc of a circle about a predetermined center, the improvement in said supporting and guiding means comprising a plurality of guide roller means for engaging said inner peripheral edge of said belt, means mounting said roller means adjacent said arc and for individual independent movement radially of said arc, and means operatively connected with said mounting means and said roller means for resiliently biasing each of said roller means radially outwardly against said edge of said belt, said means for resiliently biasing said roller means comprising a plurality of leaf spring means, each said leaf spring means having spaced end portions for rotatably supporting an adjacent pair of said roller means, and means for stationarily supporting each of said leaf spring means at points thereof intermediate said end portions.
In a curved conveyor having a generally planar ring shaped belt, and means for supporting the belt and for guiding the belt along a closed path of travel having first and second generally parallel, spaced apart runs with an inner peripheral edge of the belt substantially defining an arc of a circle about a predetermined center, the improvement in said supporting and guiding means comprising a plurality of guide roller means for engaging said inner peripheral edge of said belt, means mounting said roller means adjacent said arc and for individual independent movement radially of said arc, and means operatively connected with said mounting means and said roller means for resiliently biasing each of said roller means radially outwardly against said edge of said belt, said means for resiliently biasing said roller means comprising a plurality of race means, corresponding in number to the number of said roller means, each said race means rotatably supporting a corresponding one roller means, and a plurality of spring means corresponding in number to the number of said race means, each said spring means being disposed within a corresponding one race means.
