Claims7
Machine for feeding containers to be processed by a processing unit, which comprises an accumulation conveyor (3), located upstream of the processing unit and driven by a first motor means (8), and a feeder conveyor (4), which feeds containers to the accumulation conveyor (3) and is driven by a second motor means (13), wherein the machine further comprises:
- a first sensor (5) adjacent the feeder conveyor (4), for detecting, a container (1);
- and a control unit, which controls the first motor means (8) such that a desired gap (11) is created between two adjacent containers (1) on the accumulation conveyor (3), and that the speed of the accumulation conveyor (3) and of the feeder conveyor (4) are equal during at least a partial handing over of the container (1) from the feeder conveyor (4) to the accumulation conveyor (3).
