In-line continuous checkweigher

Claim 1

In a high speed check weighing system, a frame including a platform, drive means mounted on said frame beneath said platform near the receiving end of said platform, support means carried by said frame adjacent the discharge end of said platform. endless conveyor means being disposed over said support means and said drive means and having a horizontally disposed article-supporting portion, a vertical support member included as part of said frame having a connecting arrangement at the bottom thereof, and a weight sensor having a mating connector on top thereof disposed to receive said connecting arrangement for indicating the weight of the entire endless belt checkweigher as well as the commodities transported thereover, wherein said weight sensor includes a proving ring and means disposed in different horizontal planes attached to the portions of said sensor which is adopted to deflect under weight loads to eliminate all readings except those along a single load line.

Claim 3

A system for continuously moving commodities as well as for accurately check weighing such commodities as they are transported at high linear velocities, comprising in combination; a T-shaped framework; said framework including a horizontally disposed platform suitable to support a moving belt thereon; a roller member disposed at the discharge end of said platform both to support commodities and said belt; a drive roller disposed at the receiving end of said platform disposed to be driven by a drive train supported on said framework; a drive motor, a drive train including a plurality of gear stations and drive chain for connecting to said drive roller; a third idler roller; an endless belt conveyor disposed on said drive roller, said roller member, saod platform, and said idler roller; a vertical member forming part of said T-shaped framework having a connecting arrangement at the bottom thereof comprising exclusively a beam, and a weight sensor arranged to be located under said T-shaped framework and connected thereto via said connecting arrangement for indicating the weight of commodities as differences detected in the weight of said entire belt checkweigher while commodities are being transported thereover.

Claim 4

A system for continuously moving commodities as well as for accurately check weighing such commodities as they are transported at high linear velocities, comprising in combination; a T-shaped framework; said framework including a horizontally disposed platform suitable to support a moving belt thereon; a roller member disposed at the discharge end of said platform both to support commodities and said belt; a drive roller disposed at the receiving end of said platform disposed to be driven by a drive train supported on said framework; a drive motor, a drive train including a plurality of gear stations and drive chain for connecting to said drive roller; a third idler roller; an endless belt conveyor disposed on said drive roller, said roller member, saod platform, and said idler roller; a vertical member forming part of said T-shaped framework having a connecting arrangement at the bottom thereof comprising exclusively a beam, and a weight sensor arranged to be located under said T-shaped framework and connected thereto via said connecting arrangement for indicating the weight of commodities as differences detected in the weight of said entire belt checkweigher while commodities are being transported thereover.
