Method for filling bags (1) with metered quantities (QP) of bulk products (P1;P2), characterized in that it comprises the following steps:
a) providing a first container (B11) and a second container (B21) having an assigned total volume;
b) dividing up each container (B11;B21) into two respective half-volumes (B11a,B11b;B21a,B21b), each half-volume being designed to feed product to a first station (R1) or a second station (R2) for filling bags (1), so that each container has a half-volume connected to the first station (R1) and a half-volume connected to the second station (R2) of the two stations (R1;R2);
c) providing a first predefined metered quantity (QP) of product (P1) inside the first container (B11) by dividing up the metered quantity (QP) of product into two quantities (Q1P1,Q2P1) equal to approximately half the metered quantity, each fed to a respective half-volume (B11a,B11b) of the first container (B11);
d) conveying a bag (1) to the first filling station (R1) ;
e) filling the bag (1) with the quantity (Q1P1) of product of the first half volume (B11a) of the first container (B11);
f) providing a second predefined quantity (QP2) of product (P2) inside the second container (B21), dividing up the metered quantity (QP2) of product into two quantities (Q1P2,Q2P2) equal to approximately half of the metered quantity, each fed to a respective half-volume (B21a,B21b) of the second container (B21);
g) moving the bag (1) to the second filling station (R2);
h) filling the bag (1) with the quantity (Q2P1) of product contained in the second half-volume (B11b) of the same first container (B11);
i) conveying a second bag (2) to the first filling station (R1);
j) filling the second bag (2) with the quantity (Q1P2) of product (P2) supplied from the first half-volume (B21a) of the second container (B21) ;
k) moving the second bag (2) to the second station (R2);
l) filling the second bag (2) with the second quantity of product (Q2P2) supplied from the second half-volume (B21b) of the same second container (B21);
m) feeding a new metered quantity of product (P1) to the first container (B11) with division into the two half-volumes (B11a,B11b) for a further dispensing cycle;
n) conveying the first bag (1) to the sealing station (S) and from here to the exit (113) ;
o) continuing the cycle with the steps (c-n) for the second or following bags. |
