More Information
Summary:A combination weighing and counting apparatus includes a plurality of vibrating feeders (1) arranged and mounted on a support frame and adapted to be electrically powered from an alternating current source to transport articles, a plurality of weighing hoppers (28) for measuring respective weights of the articles (M) supplied from the vibrating feeders (1), and a combination selecting device for combining weights or numbers of the articles supplied to the weighing hoppers and for selecting a combination of the articles (M) which falls within a tolerance range. To minimise vibration of the support frame so that any undesirable reduction in weighing accuracy can be suppressed, there is provided a feeder drive control device (42) for driving substantially half of the vibrating feeders (1) at a driving phase remaining vibrating feeder.
