Abstract

An automatic discharge system permits the counting and discharge of measured quantities of similar articles. The system includes a set of substantially identical discharge modules arranged in a series. Each discharge module is connected to a counting device which counts a measured quantity of articles and discharges the articles into a container, upon command. Each discharge module also includes a microprocessor, the microprocessors of the discharge modules being identically programmed. Each microprocessor receives inputs from the microprocessors in adjacent modules, anad transmits signals to the adjacent microprocessors, such that signals propagate up and down the series. A central control unit issues a 'step' signal which propagates up the series. Each time a microprocessor receives such a 'step' signal, it records a 'turn'. Each microprocessor is programmed to cause its associated counter to dump articles on one or more predetermined 'turns'. The control unit also receives signals from the last module in the series, and is programmed not to issue another 'step' signal until it has received confirmation that all modules in the series are ready for the next 'turn'. The control unit can be actuated manually, such as by a foot pedal, or automatically, such as by an automatic bagging maachine. In another embodiment, the first discharge module and control unit are combined into one module. In still another embodiment, the modules discharge articles on a 'when ready' basis, and they do so only one at a time.
