Method and apparatus for package labeling

Abstract

Labels are positioned within selected labeling regions on packages processed by a packaging system or carried by a package conveyor by means of horizontally shifting a package labeler relative to packages to be labeled in response to package dimensions which define the edges of the packages. Label positioning is illustrated in an integrated packaging machine wherein packages are weighed, wrapped and labeled. Packages are weighed at an input tray of the machine and at least one horizontal package dimension is measured and represented by package signals as a package is transported to an elevator, which raises the package into a section of wrapping material which is then wrapped about the package as one or more labels are applied. A price labeler positioned over the elevator generates price labels for the packages in response to weight signals. A label applicator also positioned over the elevator receives and applies labels to the packages as they are being wrapped. The label applicator is shifted horizontally in response to the package signals to position labels on the packages within selected labeling regions. The label positioning method and apparatus of the present invention are generally applicable and may be used to apply any labels, for example, hi-lite information labels or price labels to packages.
