  • Patent number: 6213707
    Abstract: Cardboard cartons are delivered to a soft-drink-can packaging line in boxes. The boxes are placed on a box-conveyor, from which the boxes are tranferred one by one into a bucket. The bucket holds the box while the box is overturned. In one version, the overturned box with the items inside is then moved to a magazine, where the box is pulled clear. In another version, the bucket is opened and the box pulled clear, and then the bucket is re-orientated before the items are transferred onto the magazine. The apparatus is mounted on a frame which includes uprights to which the major components can be clamped in place, allowing the apparatus to be adapted to existing machinery.
