Abstract

A roller conveyor with a plurality of rollers (3, 6, 13) which are held in a frame (2), which rollers are assigned to several sections (4), and a drivable and brakable roller (13) is assigned to each section (4) which is coupled with the other rollers (3) of the same section (4). In order to enable a simple arrangement, it is provided that the drivable and brakeable rollers (13) are each held on a fixed axle (15) on which a drive roller (6) is also held and which can be coupled with the drivable and breakable roller (13) by way of an electromecanical clutch (18′, 23′), which roller on its part is provided with an electromechanical braking device (18, 23).

Claims

1. A roller conveyor comprising a frame, several sections of rollers held in the frame;

each section comprising a plurality of support rollers, a drivable and brakable roller coupled to the support rollers, and a drive roller;

a common axle rotatably supporting the drive roller and the drivable and brakable roller;

a first switchable electromechanical clutch connecting the drivable and brakable roller to the drive roller; and

a second switchable electromechanical clutch connecting the drivable and brakable roller to a braking drive.

2. The roller conveyor of claim 1, wherein the first electromechanical clutch comprises a ring magnet which is held non-rotationally on the axle and magnetizes the drive roller, a friction lining on a side of the drive roller facing the drivable and brakable roller, and an armature non-rotationally connected to the drivable and brakable roller and held axially displaceably thereon for contact with the friction lining.

3. The roller conveyor of claim 1, wherein the second electromechanical clutch comprises a ring magnet which is held non-rotationally on the axle and has a pole face provided with a friction lining, and an armature non-rotationally connected to the drivable and brakable roller and held axially displaceably thereon.

4. The roller conveyor of claim 1, comprising a common revolving drive belt driving the drive rollers of the several sections.

5. The roller conveyor of claim 1, comprising belts operatively connecting the drivable and brakable roller of each section of rollers with the support rollers thereof.
