Dosage system of solid products for packing machines

Abstract

Dosage system applied to automatic packaging machinery, capable of measuring the mass of solid products in bulk and adjusting the final mass of the package to be baled, so that the average masses of each package result in a value pre-established, as well as the standard deviation of the masses average result in a value within a tolerance range previously defined.

1 . A dosage system for the packaging of solid products said system comprising packaging machinery comprising a primary mass meter ( 2 ) in communication with a volumetric feeder ( 1 ) and a secondary mass meter ( 3 ) in communication with particle selector ( 4 ) which enable the continuous adjustment of the mass of the packages that are being sequentially formed by the packaging machinery, to keep the standard deviation of the mass of the packages formed with a predetermined range. 
     
     
         2 . The dosage system of  claim 1 , further comprises a device for measuring the individual mass of the particle of the solid product to be packed in a packaging machinery, said system further comprising a means for determining the difference in mass for a given package in relation of the desired value for compensation throughout the batch to be packed in said packaging machinery. 
     
     
         3 . The dosage system of  claim 1 , wherein communication between the primary mass meter ( 2 ) and the volumetric feeder ( 1 ) occurs through a specific computer application that adjusts the volume the volume of material obtained from the volumetric feeder ( 1 ), to provide a mass previously established for each package. 
     
     
         4 . The dosage system of  claim 1 , wherein communication between the secondary mass meter ( 3 ) and the particle selector ( 4 ), occurs through a specific computer application that adjusts the amount of particles contributed by said particle selector ( 4 ) to provide the mass of previously established for each package. 
     
     
         5 . The dosage system of  claim 1 , said system further comprising a means for enabling the reuse of material disposed during correction procedures of the mass of the package before the formation of said package, directly in the packaging process, minimizing operating waste and, consequently, the costs of the packaging process.
