CHECKWEIGHING DEVICE, SYSTEM, AND METHOD OF OPERATION

摘要

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.

主权项

1. A checkweighing device for installation and use between an infeed conveyor and an outfeed conveyor that are arranged in parallel, spaced apart at a horizontal distance, and vertically offset relative to each other, wherein the infeed conveyor has a transport surface located at a higher level than a transport surface of the outfeed conveyor, the checkweighing device comprising:
a weighing cell with a weighing platform; a power-actuated rake; and a slide chute comprising at least one sorting gate, the slide chute adapted to direct items either to the outfeed conveyor or to a discard receiver; wherein, in the installed state of the checkweighing device between said infeed conveyor and outfeed conveyor:
the weighing platform is arranged laterally adjacent to and substantially level with the transport surface of the infeed conveyor,the slide chute adjoins an opposite side of the weighing platform and leads to the outfeed conveyor, andthe rake is arranged to move in a direction transverse to the direction of transport of the infeed conveyor, so as to perform the functions of sweeping incoming items from the transport surface of the infeed conveyor over to the weighing platform, and sweeping items that have been weighed from the weighing platform to the slide chute.
