Abstract
A checkweighing device, checkweighing systems employing one or more checkweighing devices, and methods of operation thereof. The checkweighing devices are designed for installation between parallel, spaced apart and vertically offset infeed and outfeed conveyors. Each checkweighing device includes a weighing cell with a weighing platform; a slide chute and at least one sorting gate for directing items either to the outfeed conveyor or to a discard receiver; and a power-actuated rake for sweeping incoming items from the infeed conveyor to the weighing platform, and sweeping weighed items from the weighing platform to the slide chute. While in no way limited to such a use, exemplary checkweighing device, system and method embodiments are well-suited for automatically checking the individual weights of small articles of high value, and/or other items that need to be weighed with high accuracy.
