ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a bucket and a product stuffer utilising the bucket.
BACKGROUND OF THE INVENTION
Product stuffers are known which push a sheaf of products from an open-ended bucket into a carton. While these are suitable where the sheaf of products has a height no greater than the height of the carton, they cannot be used to stuff a sheaf of products into cartons having a lesser height than the sheaf.
SUMMARY OF THE INVENTION
The present invention provides an open-ended bucket with co-operating features on opposed walls which re-orient products in a sheaf of products so that the height of the sheaf is changed. This can, for example, be used to tilt products in a sheaf of upstanding products over to form a sheaf of shingled products so that the sheaf of shingled products can be stuffed into a carton having a height less than the height of the sheaf of upstanding products.
Accordingly, the present invention comprises a bucket comprising: first and second substantially opposite walls extending between an open inlet end and an open outlet end, each of said walls having cooperating features arranged such that a sheaf of products moved through said bucket in a direction from said inlet end to said outlet end is urged by engagement with said features to twist about an axis substantially parallel to said direction, thereby to reorient the products as they are moved through the bucket.
