Abstract
A checkweighing station includes a weigh platform mounted on a load cell which in turn is mounted on a rotatable shaft so that the entire assembly can be rotated to tilt the platform in one direction for an acceptable weight of a weighed item and in another direction for a rejected weight or weight of a different catgegory. A memory device can determine a trend and make adjustments in a production process.

Checkweighing apparatus for accepting or rejecting items by weight comprising a weigh station in a fixed stationary location including a platform at said fixed stationary location having an area for holding an item to be weighed, a load cell under said platform, said load cell for generating a signal as a function of weight of an item on said platform, and a controller including a motor responsive to said signal for tilting said platform and said load cell to remove said item from said platform at said fixed stationary location when said item is outside of a desired weight range and returning said platform to its original position.
Checkweighing apparatus for accepting or rejecting items by weight comprising a weigh station in a fixed stationary location including a platform at said fixed stationary location having an area for holding an item to be weighed, a load cell mounted on a beam under said platform, said load cell for generating a signal as a function of weight of an item on said platform, and a controller responsive to said signal for tilting said platform and said load cell to remove said item from said platform at said fixed stationary location when said item is outside of a desired weight range and returning said platform to its original position.
Checkweighing apparatus for accepting or rejecting items by weight comprising a weigh station in a fixed stationary location including a platform at said fixed stationary location having an area for holding an item to be weighted, a load cell under said platform, said load cell for generating a signal as a function of weight of an item on said platform, said load cell being mounted substantially directly under its point of attachment to said platform, and a controller responsive to said signal for tilting said platform and said load cell to remove said item from said platform at said fixed stationary location when said item is outside of a desired weight range and returning said platform to its original position.
Weighstation apparatus for accepting or rejecting items by weight comprising
- (a) a substantially horizontal platform for holding items to be weighed
- (b) a beam supporting said platform at a first end thereof
- said beam including a single point load cell and being mounted on a pivot at a second end, said load cell for generating a signal as a function of weight of an item on said platform, and
- (c) means responsive to said signal for tilting said platform and said beam on said pivot when said item is outside of a desired weight range and returning said platform to its original substantially horizontal orientation, said platform, said beam, and said means for tilting being fixed in a stationary location.
