Abstract
Containers which are wider than they are high are delivered to a pair of belts spaced to support the container below its widest upper edge. The containers are delivered to the belts by a chute which delivers the containers in one of two orientations either bottom leading or bottom trailing relative to the conveyor direction.
Claims4
Method of orienting open ended containers which are a surface of revolution about the intended vertical axis thereof, said containers being shaped so that their largest diameter is located at the open end, and so shaped that their maximum vertical dimension is less than said largest diameter, comprising the steps of:
- providing a pair of belts each of which is arranged to provide a flight to partly support such a container below said largest diameter,
- said flights being arranged to be parallel, directed in the same travel direction and spaced to support diametrically opposed portions of said largest diameter,
- causing said belts to operate so that each of said flights move in the travel direction,
- delivering such containers downwardly toward said belt flights, in one of two orientations, i.e. with the bottom of the container leading or trailing in the direction of belt travel so that the downwardly leading surface of the largest diameter of a container will pass between said belt flights and then contact both said flights,
- the angle of delivery of such containers being selected with a range so that the plane of the portion of largest diameter intersects said flights along a line approximately perpendicular to the travel direction and the slope of such planes is from the vertical to directions downward and rearward relative to the travel direction.
Method of orienting open ended containers surrounded by a rim which are a surface of revolution about the vertical axis thereof, whose rim is the largest diameter about said axis and whose vertical dimension is less than the diameter of said rim and whose centre of gravity is displaced from said rim, comprising the steps of:
- providing a pair of belts each of which is arranged to provide a flight to support the rim of such a container,
- said flights being arranged to be parallel, designed to be moved by said belts in the same travel direction and spaced to support diametrically opposed portions of said rim,
- causing said belts to operate so that said flights move in the travel direction,
- delivering such containers downwardly toward said belt flights, in one of two orientations, i.e. with the bottom of the container leading or trailing in the direction of belt travel, so that the outer surface of said rim will pass between said belt flights and then be halted by the flights at opposed points of contact,
- the angle of delivery of said containers being selected within a range, so that the planes of the portion of largest diameter intersect said flights along a line approximately perpendicular to the travel direction and the slope of such planes is from the vertical to directions downward and rearward relative to the travel direction.
