Abstract
Food cans are slid across a vertically-oscillating weigh platform while being guided by contacting means bearing against their upstream side surfaces. The contacting means comprise a pair of rollers rotatable about an axis transverse to the direction of sliding motion of the cans, and bearing against the vertical side surfaces of the cans above the bottom bead of the can. This avoids the indentations formed in the lug contactors of the prior art after many contacts with the bead of the can, and thereby improves the weighing accuracy.
Claims6
In a system for slidingly conveying across a vibratory weighing platform a train of containers each to be weighed as it slides across said platform and each having a peripheral flange portion adjacent the bottom thereof extending horizontally outward from at least the upstream side of said container, comprising chain means moving horizontally below the top of said platform, and contacting means mounted on said chain means for contacting the upstream sides of said containers as they move across said platform, the improvement, wherein:
- said contacting means comprises a contactor extending upwards from said chain means and adapted to extend around said flange portion without contacting it and into contact with an upstream side portion of said container which is located adjacent but above said flange portion.
