ABSTRACT:
A workstation (1) in an assembly line for placing components onto workpieces is associated with a conveyor (3) for conveying the workpieces into and out of workstation (1). A component placer (6) places components from a component feeder (5) onto the workpieces. Controller (4) controls conveyor (3) and component placer (6) and determines placement operations for a workpiece. Information may be provided by a preceding workstation to controller (4) to determine the operations. When an idle status signal from a subsequent workstation is received, controller (4) determines information on how much of the operations have been executed or unexecuted by workstation (1). This information, associated with the workpiece, is then provided to the subsequent workstation when the workpiece is conveyed to the subsequent workstation. Thereafter, workstation (1) provides an idle status signal to the preceding workstation to request for another workpiece.
