Abstract

The invention relates to a roller arrangement (7) for a stowing roller conveyor, comprising a stationary roller axle (20) arranged in a support frame (4) of the stowing roller conveyor, with a driving roller (9) and a conveying roller (10) adapted to be driven and/or braked, if necessary, being rotationally supported on said roller axle; as well as a clutch system (12) arranged between said driving and conveying rollers and comprising clutch components (14, 15) adjustable in relation to one another via a setting device (13), whereby at least one of the clutch components (14, 15) is axially adjustably arranged on the roller axle (20) and adjustable against at least one spring element (36), from a switching position in which it is engaged, into a switching position in which it is disengaged, and whereby the first clutch component (14) is drive-connected with the conveying roller (10), and the other clutch component (15) with the driving roller (9). A setting device (47) for setting a force of contact pressure to be adjusted between the clutch components (14, 15) depending on the weight of the piece goods (14), is arranged between the conveying roller (10) and the first clutch component (14). Furthermore, the invention relates to a stowing roller conveyor in which the roller arrangement (9) as defined by the invention is arranged.

Dependent claims

A roller arrangement (7) for conveying piece goods (18) along a stowing roller conveyor (1), comprised of a stationary roller axle (20) arranged in a support frame (3) of the stowing roller conveyor (1);

a driving roller (9) and a conveying roller (10) adapted to be driven and/or braked, if need be, rotationally mounted on said roller axle;
as well as a mechanically actuated clutch system (12), particularly a friction clutch system arranged between said rollers (9) and (10), said clutch system comprising clutch components (14, 15) adjustable against one another via a setting device (13);
whereby at least one of the clutch components (14, 15) is axially adjustable against the action of at least one spring element (36), from a switching position in which such component is engaged, into a switching position in which it is disengaged, and the first clutch component (14) is drive-connected with the conveying roller (10), and the other clutch component (15) with the driving roller (9);
and coupling surfaces (43, 44) of the clutch components (14, 15), such surfaces facing each other, are supported against one another by a force of contact pressure in the switching position in which they are engaged, wherein a self-adjusting setting device (47) is arranged between the conveying roller (10) and the first clutch component (14) adjustable on the roller axle (20), said setting device comprising at least two transmitting elements (42, 48;
117, 118) engaged via a tooth system (49) and adjustable against one another in the axial and/or peripheral directions in relation to the roller axle (20);
the first clutch component (14), in the presence of a relative movement between the conveying roller (10) and the first clutch component (14), is automatically adjusted toward the other clutch component (15) in the peripheral direction of said conveying roller, and in the axial direction relative to the roller axle (20);
and the coupling surface (43) of the first clutch component (14) is pressed against the coupling surface (44) of the other clutch component (15) with a force of contact pressure set depending on the weight of the piece goods (18) transported by the conveying roller (10), until slip-free friction grip is reached between the two clutch components (14, 15).

A roller arrangement (7) for a stowing roller conveyor (1), comprising a stationary roller axle (20) arranged in a support frame (2) of the stowing roller conveyor (1);

a driving roller (9) and a conveying roller (10) adapted to be driven and/or braked, if necessary, and rotationally supported on said roller axle;
as well as a mechanical clutch system arranged between said driving and conveying rollers, said clutch system comprising clutch components (87, 88, 89) adjustable relative to one another via a setting device (13), wherein the first clutch component (87) is formed by the conveying roller (10) with a coupling surface (90) arranged concentrically in relation to the longitudinal center axis (56) of the roller axle (20);
the second clutch component (88) is formed by the driving roller (9) or a driving roller (108) drive-connected to said roller (9);
and the third clutch component (89) arranged between the first and second clutch components (87, 88) is formed by a transmitting roller (91);
and said transmitting roller (91), the latter being eccentrically supported and adjustable from a switching position in which it is disengaged, into a switching position in which it is engaged, and drive-connected in the latter switching position with coupling surfaces (90, 93) of the first drive-connected with the first and the second clutch components (87;
88);
or one of the coupling surfaces (90;
93) of the first and second clutch components (87;
88) is formed eccentrically to the longitudinal center axis (56) of the roller axle (20) of the first clutch component (87).
