Patent ID: 8317011

Claim:
An apparatus for feeding containers to a downstream processing unit, which receives the containers with a distance between them, comprising: an infeed worm, by which a required distance between the containers is settable via a length of the infeed worm, wherein at an input end of the infeed worm the containers arrive in contact with each other and at an exit end of the infeed worm adjacent containers are spaced apart by the required distance; a groove formed along the length of the infeed worm; and first and second drivable conveyor belts which are arranged in such a way with respect to the infeed worm that the containers are in simultaneous contact with the groove of the infeed worm and with the first and second driveable conveyor belts, wherein: the first conveyor belt at the input end of the infeed worm has a lower velocity in the direction of transport than the second conveyor belt at the exit end of the infeed worm; the first and the second conveyor belt are arranged in parallel; and the directions of transport of the first and of the second conveyor belt are tilted by an angle with respect to an axis of rotation of the infeed worm and the containers reach the input end of the infeed worm via the first conveyor belt, wherein: a pitch of the infeed worm increases from the input end of the infeed worm to the exit end of the infeed worm; the infeed worm is arranged such that the increase in the pitch of the infeed worm causes the containers to be increasingly pushed onto the fast moving second conveyor belt; and, the containers exit the infeed worm at the exit end on the second conveyor belt.
