Abstract

A roller conveyor in an as such known manner includes a plurality of driven rollers disposed in two parallel tracks. With each driven roller a drive motor is associated. From a first voltage source a first set of the driven rollers is supplied, wherein a second voltage source is provided, from which a further set of the driven rollers is supplied. This arrangement offers a high degree of redundancy in the event of the failure of individual components of the roller drive, thereby guaranteeing an emergency operation in such a situation.

Claims (17)

1. A roller conveyor comprising:

a plurality of driven rollers disposed in two parallel tracks;

a plurality of drive motors for driving the rollers;

at least one voltage source, from which the drive motors are supplied;

an emergency operation system including:

a separate drive motor operatively connected to one of the plurality of driven rollers;

a first voltage source operatively connected to a first set of the driven rollers; and,

at least one further voltage source operatively connected to at least one further set of the driven rollers; and,

a means for directionally stabilizing goods transportation, wherein driven rollers disposed on the same track are operatively connected to different voltage sources.

2. The roller conveyor of claim 1 , wherein two voltage sources are provided.

3. The roller conveyor of claim 2 , wherein driven rollers supplied from different voltage sources are disposed on the same track.

4. The roller conveyor of claim 3 , wherein the drive motors are 24 volt motors.

5. The roller conveyor of claim 3 , wherein the drive motors are hub motors, which with the driven rollers form a sub-assembly.

6. The roller conveyor of claim 2 , wherein the drive motors are 24 volt motors.

7. The roller conveyor of claim 2 , wherein the drive motors are hub motors, which with the driven rollers form a sub-assembly.

8. The roller conveyor of claim 1 , wherein the drive motors are 24 volt motors.

9. The roller conveyor of claim 8 , wherein the drive motors are hub motors, which with the driven rollers form a sub-assembly.
