Abstract
Abstract First and second compound chutes constituting a collecting chute assembly each comprises an outer chute of inverted, bisected frusto-conical shape having a semicircular upper opening and a semicircular lower opening, and an inner chute of inverted, bisected conical shape disposed within the outer chute via a partitioning plate. The overall chute assembly is of inverted frusto-conical shape and is constructed by uniting the compound chutes by bringing their respective partitioning plates into face-to-face contact, the assembly defining two discharge routes. At the lower ends of the chutes, one discharge route communicates the inner chute of the first compound chute with the outer chute of the second compound chute, and the other communicates the inner chute of the second compound chute with the outer chute of the first compound chute. Weighed articles introduced into the inner chute of one of the compound chutes will be guided into the outer chute of the other compound chute to join weighed articles introduced directly into the outer chute, the combined articles being discharged from said outer chute to a point outside the system. The arrangement is such that time required for articles to be discharged from both discharge passages is approximately the same. Furthermore, a collecting chute for collecting weighed articles discharged from an automatic weighing system is divided into left and right sections and has an inner article receiving portion defining an opening and an outer article receiving portion defining an opening at the upper end thereof, and two article discharge portions provided side-by-side at the bottom end thereof. The left and right sections each include an upper, outer chute and a contiguous lower, outer chute, an upper, inner chute and a contiguous lower, inner chute, and a discharge chute contiguous to the lower, outer chute. The left lower, inner chute has an outlet which extends solely into the right lower, outer chute, and the right lower, inner chute has an outlet which extends solely into the left, lower outer chute, thereby communicating the left and right lower, inner chutes with the right and left discharge chutes, respectively. The upper, outer chutes and the upper, inner chutes are capable of being disassembled into plural component parts.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
118 words
A method of collecting weighed articles discharged from a combinatorial weighing system in which first and second compound chutes, each comprising an outer chute and an inner chute, are combined into a unitary body, comprising the steps of: discharging weighed articles into the outer chute of the first compound chute and the inner chute of the second compound chute, or into the outer chute of the second compound chute or the inner chute of the first compound chute; discharging the weighed articles from two discharge routes defined by the first and second compound chutes; and separately collecting and recovering the weighed articles from each discharge route and separately discharging the collected and recovered articles to an external point.
Claim 2
Independent Claim
118 words
A method of collecting weighed articles discharged from a combinatorial weighing system in which first and second compound chutes, each comprising an outer chute and an inner chute, are combined into a unitary body, comprising the steps of: discharging weighed articles into the outer chute of the first compound chute and the inner chute of the second compound chute, or into the outer chute of the second compound chute or the inner chute of the first compound chute; discharging the weighed articles from two discharge routes defined by the first and second compound chutes; and separately collecting and recovering the weighed articles from each discharge route and separately discharging the collected and recovered articles to an external point.
Claim 3
Independent Claim
328 words
An apparatus for collecting weighed articles discharged from a combinatorial weighing system having a plurality of weighing hoppers from selected ones of which the articles are released following weighing, comprising: a collecting chute assembly which includes first and second compound chutes each comprising an outer chute of inverted, bisected frusto-conical shape having a semicircular upper opening and a semicircular lower discharge opening, and an inner chute of inverted, bisected conical shape disposed within said outer chute and having a semicircular upper opening and an opening at a lower end thereof, said first and second compound chutes of said collecting chute assembly being united such that the diameters of the semicircular upper openings of the inner and outer chutes of said first compound chute coincide with the diameters of the semicircular upper openings of the inner and outer chutes, respectively, of said second compound chute, and such that the diameter of the semicircular lower discharge opening of said first compound chute coincides with the diameter of the semicircular lower discharge opening of said second compound chute; prescribed ones of the plurality of weighing hoppers releasing weighed articles selectively into (a) the outer chute of said first compound chute and the inner chute of said second compound chute, and (b) the outer chute of said second compound chute and the inner chute of said first compound chute; first discharge port means communicating with the lower discharge opening of the outer chute of said first compound chute and with the opening of the inner chute of said second compound chute, for gathering the weighed articles released by the prescribed weighing hoppers into the last-mentioned outer chute and inner chute; and second discharge port means communicating with the lower discharge opening of the outer chute of said second compound chute and with the opening of the inner chute of said first compound chute, for gathering the weighed articles released by the prescribed weighing hoppers into the last-mentioned outer chute and inner chute.
Claim 4
Independent Claim
328 words
An apparatus for collecting weighed articles discharged from a combinatorial weighing system having a plurality of weighing hoppers from selected ones of which the articles are released following weighing, comprising: a collecting chute assembly which includes first and second compound chutes each comprising an outer chute of inverted, bisected frusto-conical shape having a semicircular upper opening and a semicircular lower discharge opening, and an inner chute of inverted, bisected conical shape disposed within said outer chute and having a semicircular upper opening and an opening at a lower end thereof, said first and second compound chutes of said collecting chute assembly being united such that the diameters of the semicircular upper openings of the inner and outer chutes of said first compound chute coincide with the diameters of the semicircular upper openings of the inner and outer chutes, respectively, of said second compound chute, and such that the diameter of the semicircular lower discharge opening of said first compound chute coincides with the diameter of the semicircular lower discharge opening of said second compound chute; prescribed ones of the plurality of weighing hoppers releasing weighed articles selectively into (a) the outer chute of said first compound chute and the inner chute of said second compound chute, and (b) the outer chute of said second compound chute and the inner chute of said first compound chute; first discharge port means communicating with the lower discharge opening of the outer chute of said first compound chute and with the opening of the inner chute of said second compound chute, for gathering the weighed articles released by the prescribed weighing hoppers into the last-mentioned outer chute and inner chute; and second discharge port means communicating with the lower discharge opening of the outer chute of said second compound chute and with the opening of the inner chute of said first compound chute, for gathering the weighed articles released by the prescribed weighing hoppers into the last-mentioned outer chute and inner chute.
