Abstract
Containers are conveyed past an apparatus for inspecting the bottom of the containers for contamination, flaws and foreign bodies. To that end, the containers are fed into the inspection apparatus by a first conveyor, and guided out of the inspection apparatus on a second conveyor, in which a gap is left between the first and second conveyors, within which the containers are not supported, at least not over the whole of their under surface. The containers on the first conveyor, within the gap and on the second conveyor are guided by side guidance apparatus and are conveyed under dynamic pressure, at least within the gap.
Claims19
A method for conveying a plurality of containers past an inspection apparatus for inspecting a bottom side of a plurality of containers comprising the steps of:
- feeding the container into the inspection apparatus by means of a first conveyor;
- guiding the container out of the inspection apparatus on a second conveyor;
- leaving a gap between the first and second conveyors within which the containers are at least partly unsupported and within which the containers are inspected;
- guiding the containers on the first conveyor, within the gap, and on the second conveyor by a side guidance apparatus;
- conveying the containers at least within the gap under dynamic pressure;
- and
- wherein the dynamic pressure is a mutual pressure of the containers sufficient to hold the containers within the gap between the first and second conveyors so that the friction between the containers pressing against each other prevents the containers from sliding vertically with respect to each other.
A device conveying a plurality of containers past an inspection apparatus for inspecting a bottom of the containers comprising:
- a first conveyor for guiding a plurality of containers having a bottom surface into an inspection apparatus;
- a second conveyor for guiding a plurality of containers from the inspection apparatus;
- wherein a gap is left between the first and second conveyor within which the containers are at least partly unsupported on the bottom surface and in which the inspection apparatus inspects the containers within the gap;
- at least one side guidance apparatus extending on both sides of the first and second conveyors and the gap, wherein the side guidance apparatus permits the containers to be conveyed under dynamic pressure;
- and
- wherein the dynamic pressure is a mutual pressure of the containers sufficient to hold the containers within the gap between the first and second conveyors so that the friction between the containers pressing against each other prevents the containers from sliding vertically with respect to each other.
