A continuous continuous packing machine for packing groups of articles in paperboard boxes, and a method for adjusting the composite profile of the loader parts of a loader to the drum to correspond to the profile of the articles to be loaded

摘要

continuous motion packaging machine for packing article groups into cartons, drum loader, method for adjusting the composite profile of the impelling faces of a drum loader to match the profile of the articles to be pushed, and drum loader for moving groups of sequential stall articles into adjacent open boxes a step-step drum cadenced magazine for a packaging machine has a front magazine arm assembly and a rear magazine arm assembly. Each loader arm assembly has a loader arm, which supports a loader face at one end, and the loader arm is extendable and retractable on guide rails. one loader arm is driven in a downstream direction by a first set of endless chains, and the other is driven by a second set of endless chains. one of the endless chains may have its cadence advanced or retarded relative to the other to move the loader arms farther or closer as they move downstream. This moves the loader faces farther or closer to each other, and the loader faces have interlocking claws when the loader faces are joined together. thus, a composite face of the magazine having a predetermined area may be formed by moving the magazine arm assemblies closer or further apart from one another. The composite face of the magazine is sized in each case to correspond to groups of articles such as beverage cans of different sizes and / or different configurations.
