Abstract: Disclosed is a collecting chute into which articles weighed by a plurality of weighing machines are discharged for delivery to a subsequent processing step. The collecting chute comprises an upper chute including a plurality of discrete chute members corresponding to the plurality of weighing machines, and a lower chute disposed below and engaging with the upper chute. A bracket which can be freely attached to and detached from a frame is affixed to each discrete chute member at the central portion thereof, and each chute member is provided at its lower end with a pin for engaging a hole formed in the upper edge of the lower chute.

Abstract: Disclosed is a combinatorial weighing apparatus for combining weight values of articles to-be-weighed respectively placed on a plurality of juxtaposed weighing machines, selecting a combination of the articles having a weight equal or closest to a target weight and delivering the selected articles. Such combinatorial weighing apparatus comprises pushing members which can move frontward and backward on respective bowls of the plurality of juxtaposed weighing machines, a driver unit which selectively moves the pushing members frontward and backward, these pushing members corresponding to the weighing machines with the selected batches of the articles placed thereon, and a conveyor which is disposed along the juxtaposed weighing machines and which conveys the batches delivered by the pushing members.

Abstract: A weighing apparatus of the type which weighs articles through use of a load cell having strain gauges attached thereto, the apparatus including a sealed vessel filled with a liquid of a specific gravity greater than unity for housing the load cell which is immersed in the liquid, a diaphragm provided on the sealed vessel so as to close an opening formed in a portion of the vessel, a supporting member for supporting a container carrying the articles to be weighed, and a connecting member for mechanically connecting the supporting member with a load-receiving portion of the load cell through the intermediary of the diaphragm.

Abstract: An automatic weighing apparatus with a dispersion feed apparatus comprising a plurality of feed troughs adapted to be separately vibrated and radially arranged around the outer periphery of a dispersion table which performs spiral reciprocating vibratory motion, the feed troughs being separately vibrated at predetermined times to feed articles to associated weighing units.

Abstract: A combinatorial weighing system designed for weighing out a desired number or weight of articles, wherein groups of articles are respectively weighed by a plurality of weighing machines, combinatorial addition is performed on all or a fixed number of possible combinations for weighed values obtained, a particular combination whose combination value is equal or the closest to a set value is selected, and articles are discharged from the weighing hoppers corresponding to the selected combination. It is contemplated to improve performance of this system by ensuring that groups of articles successively discharged from the weighing hoppers are collected separately one from the other without intermingling. To that end, an intermediate shutter is provided in a collecting chute.
