Abstract
An improved belt supporting and guiding apparatus enabling belt travel in other than a linear path wherein there is a base frame and a second frame mounted on the base frame; the second frame has center, left and right portions with surfaces which together define a belt support surface delimiting a concavity that is shaped other than as a constant arc of a circle so that rotation of the second frame on mounting rollers is about an instant center whose spatial location changes constantly.
Claims12
An improved belt supporting and guiding apparatus for use in a conveyor system having a base frame and a continuous belt to move material in a horizontal plane along a non-linear path from a loading site to a discharge site, said supporting apparatus comprising:
- (a) a second frame mountable for rotation on the base frame and having a center portion and left and right side portions which extend upwardly and outwardly from the center portion, and wherein said second frame center portion and left and right side portions comprise (i) substantially linear main body parts having longitudinal and transverse dimensions;
- and (ii) a flange that extends outwardly from the main body part of each of the second frame portions in a direction substantially normal to the direct of the transverse dimension thereof;
- (b) rollers mounted for rotation within the second frame to receive the continuous belt;
- and
- (c) means movably connecting the base frame to the second frame at locations on the left and right side portions thereof so that variation in longitudinally directed belt tension will cause the second frame to rotate on the rollers about an instant center whose spatial location changes constantly during rotation of said second frame.
A conveyor system comprising:
- (a) a base frame;
- (b) a continuous belt to move material in a horizontal plane along a non-linear path from a loading site to a discharge site;
- (c) a second frame mountable for rotation on the base frame and having a center portion and left and right side portions which extend upwardly and outwardly from the center portion and wherein the center portion and left and right side portions comprise
- (1) substantially linear main body parts having longitudinal and transverse dimensions;
- and
- (2) a flange that extends outwardly from the main body part of each of the second frame portions in a direction substantially normal to the direction of the transverse dimension thereof;
- (d) rollers mounted for rotation within the second frame to receive the continuous belt;
- and
- (e) means movably connecting the base frame to the second frame at locations on the left and right portions thereof so that variation in longitudinally directed belt tension will cause the second frame to rotate on the rollers about an instant center whose spatial location changes constantly during rotation of the second frame.
