ABSTRACT:
The present invention provides a conveyorized system for weighing and labeling products in packages and having multiple conveyor sections each of which is driven by an individual variable speed motor. A computer is supplied and connected to each of the variable speed motors. The computer contains data relating speed of operating each motor for a particular package style in the computer memory. An operator inputs a package code to the computer, which locates the package information stored in memory and signals the variable speed motors as to the desired speed for each conveyor. Similar information is maintained in the computer memory for each package as to dimensions, such that the computer signal output includes commands to several servo motors which are connected to adjust spacing between vertical control belts to accommodate the package and the positioning of a label applicator to suit. A further control involves a pair of sensors placed near the exit of the system to detect a blockage of package flow and, through computer programmed analysis, command an input conveyor to adjust operating speed accordingly.
