Abstract
A combinational weighing device comprises a plurality of weighing cells and corresponding associated weighing hoppers (W.sub.1 . . . W.sub.10) and an outlet-side transfer device (5) for supplying weighed products into a package to be arranged therebelow. In conventional manner a controller (6) has an input connected with the output of the load cells and an output connected to respective drives for the closable outlets of the weighing hoppers. The drives of the outlets of the weighing hoppers are controlled in such a manner that a corresponding subcombination of several weighing hoppers is selected for forming a total amount to be supplied into a package. In order to increase the speed in cases where the individual weights of the articles differ by a sufficiently small amount the controller is designed to be switched to a second operational mode wherein the controller drives the outlets of the weighing hoppers so that each weighing hopper can be selected independently of the other weighing hoppers. This considerably increases the weighing speed.
