System for controlling feeders of a package assembly apparatus

A system for use in connection with a package assembly line, wherein the package assembly line has a piece feeder, a component feeder, and a transport, wherein the transport is divided into transport spaces, wherein the piece feeder is arranged to feed a first piece to a first transport space, wherein the piece feeder is arranged to feed a second piece to a second transport space, wherein the component feeder is arranged to feed a first component to the first transport space, wherein the component feeder is arranged to feed a second component to the second transport space, wherein the first component has a first component identifier thereon, wherein the second component has a second component identifier thereon, wherein the first piece has a first piece identifier associated therewith, and wherein the second piece has a second piece identifier associated therewith, the system comprising:

• storing means for storing the first and second piece identifiers in a piece data file;
• detecting means for detecting the first component identifier from the first component as the first component is fed by the component feeder toward the first transport space;
• comparing means for comparing the detected first component identifier to the first piece identifier;
• and,
• list re-sequencing means for re-sequencing the first and second piece identifiers in the piece data file if the first component identifier fails to match the first piece identifier.

A system for use in connection with a package assembly line, wherein the package assembly line has a piece feeder and a component feeder, wherein the piece feeder is arranged to feed pieces to a transport of the package assembly line, wherein the component feeder is arranged to feed components to the transport of the package assembly line so that the components and the pieces are combined into packages, and wherein the components have corresponding component identifiers thereon, the system comprising:

• storing means for storing a piece data file having piece identifiers;
• detecting means for detecting a component identifier from a component;
• comparing means for comparing the detected component identifier to a corresponding piece identifier;
• and,
• means for modifying the piece data file if the detected component identifier fails to match the corresponding piece identifier.
