Abstract
An automatic combinatorial weighing apparatus includes a double collection chute assembly disposed in delivery paths for passage of articles to be weighed. The double collection chute assembly includes an inner collection chute having an outlet and a pair of outer collection chutes having respective outlets, the outlets being connected to timing hoppers, respectively. Articles flow down the inner and outer collection chutes at as equal speeds and in as equal times as possible, the speeds being increased as much as possible, due to valleys created by flat plates which form the chutes. To prevent an increase in noise produced by hitting engagement of the articles with the chutes as the articles flow down the chutes at high speeds, a vibration damper having a vibration-restriction damping capability is disposed in an area of the delivery paths for damping the vibration to suppress the noise.
