Abstract
A weighing system for material suspended from a rail or trolley. The system includes a transition track between the regular track and the weighing track to avoid oscillation of pressure on the weighing track which causes difficulty in rapidly arriving at a proper weight. The transition track is biassed away from the weighing track so as not to cause a false weight reading. It also includes a novel trolley moving mechanism for moving the trolley as it passes over the weighing mechanism.
Claims27
A system for weighing a load on a trolley comprising a divided main track, trolley means rolling in one direction on said main track, weighing means for a weighing track section bridging the division in said main track section , weighing means for measuring the weight on said weighing track seciton, a transition support section between said main track and said weighing track section, said rolling of said trolley means in said one direction defining an entrance end and a discharge end of said transition support section and an entrance end of said weighing track section, said entrance end of said transition support section being in contact with and rockingly supported on a part of said main track at a pivot line not further in said one direction than vertically below the entrance end of said transition support section, said discharge end of said transition support section being formed to engage and to be supported by said entrance end of said weighing track section.
A system for weighing a load on a trolley comprising a divided main track, a trolley rolling in one direction on said main track, a weighing track section bridging the division in said main track, a scale being able to measure the weight on said weighing track section, a transition support section between said main track and said weighing track section, said rolling of said trolley in said one direction defining an entrance end and a discharge end of said transition support section and an entrance end of said weighing track section, said entrance end of said transition support section being rockingly supported on a part of said main track about a pivot line not further in said one direction than vertically below the entrance end of said transition support section, said discharge end of said transition support section being formed to engage and to be supported by said entrance end of said weighing track section.
A system for weighing a load on a trolley comprising:
- a. a divided main track;
- b. a trolley rolling in one direction on said main track;
- c. a weighing track section bridging the division in said main track;
- d. a scale being able to measure the weight on said weighing track section;
- e. a transition support section between said main track and said weighing track section, said rolling of said trolley in said one direction defining an entrance end and a discharge end of said transition support section and an entrance end of said weighing track section, said entrance end of said transition support section being rockingly supported on a part of said main track, said discharge end of said transition support section being formed to engage and to be supported by said entrance end of said weighing track section;
- and
- f. a spring biasing said discharge end of said transition support section away from said weighing track section until the weight of said trolley on said transition support section overcomes said spring bias.
A system for weighing a load on a trolley comprising:
- a. a divided main track;
- b. a plurality of trolleys rolling in one direction on said main track;
- c. a weighing track section bridging the division in said main track;
- d. a scale being able to measure the weight on said weighing track section;
- e. a primary transport system positioned to engage said plurality of trolleys to move said trolleys along said main track;
- and
- f. an auxiliary transport system engagable with an individual one of said plurality of trolleys to move said individual trolley along said weighing track section at a linear speed slightly greater than the motion along said main track so as to disengage said individual trolley form said primary transport system while said individual trolley is on said weighing track section.
