Abstract
Abstract A weighing system includes a weighing apparatus composed of distributive table, a plurality of radial supply troughs disposed around the peripheral edge of the distributive table for being supplied with articles to be weighed from the distributive table, a plurality of weighing units supporting respective openable weighing hoppers for weighing articles supplied to the weighing hoppers, at least one of the distributive table and the radial supply troughs having a slide surface slanted radially outwardly to a large extent for allowing the articles to slide thereon, each of the radial supply troughs having a radially outer distral end disposed one of the weighing hoppers, and a collection chute disposed below the weighing hoppers. A liquid drain device is disposed at the distal end of each of the radial supply troughs. A shutter is interposed between each of the radial supply troughs and a corresponding one of the weighing hoppers. The radial supply troughs are supported on respective vibrators which are supported by detachable coil springs on a base plate. The weighing apparatus also includes a device for transmitting an output signal through space when the articles supplied to the distributive table reach a prescribed amount.
