Abstract

Improved assembly perfected for bagging and automatic weighing of powdery products, which being constituted from a scale and conveyor by traditional worm screw, essentially characterized in that on the platform of the scale is installed a frame that supports a hollow cylindrical portion on whose edge lower is the mouth of the sack to be filled, which receives the product, for example flour, through the tubular conduit in which there is the conveyor shaft or spindle, whose conduction has the particularity of disposing in its discharge chute, of an auxiliary chamber in which an agitator has been installed that is moved by a motor independent of the one that rotates the flour transporting spindle, both motors being governed by switches for this purpose, mounted on the mobile arm of the scale, so that when reaching the same a position next to the one of coincidence with the "faithful", jumps the switch of the motor main, thus paralyzing the spindle so that the filling of the bag continues to exactly complete the weighing, by the amount of product that at that time existed in the auxiliary chamber or reservoir of the hopper, whose agitator stops working, and therefore supply product, when the arm of the lever coincides with the index of the faithful, that is, when the weighing has been completed.
