摘要： A multiple weighing apparatus with dual acting hopper gates mechanism comprises a feeding device conveying articles to be weighed and packed to a weighing section of the apparatus. The articles which are transferred into the weighing section are weighed and a portion of which having a desired weight is then allowed to move into a packing section to be packed therein. Each pack of the articles will have a desired weight. The weighing section comprises a plurality of pool hoppers and weighing hoppers controlled by a central controller. Each of the hoppers comprises a body having therein a space for receiving the articles and a discharge port closable by two gates. A Stephenson III type six-bar mechanism is adapted to operate the gates with the gates being the output links thereof. A pushing rod which is controlled by the central controller is used to move the input link of the six-bar mechanism to open the gates. A returning spring is provided in ,such a way that when the gates are opened, potential energy is stored therein and when the pushing rod is retracted back, the potential energy of the spring is released to move the gates back to the closed position.
