Method for Adjustment of System for Filling of Big Bags, and System for Filling of Big Bags

Abstract

A system for filling of big bags of various heights with material and a method for adjusting thereof, wherein a big bag is to be placed with its filling spout around an outer pipe and the bottom of the big bag rests on and underlying surface. The outer pipe is telescopically engaged to a feed pipe. The feed pipe is in sections extendible. The feed pipe is designed to fill a determined quantity of material in a vertical stream from an overlying dosage unit via the outer pipe and down into the big bag. The feed pipe at its upper connection includes at least one radial continous interface surface design to attach to another feed pipe's downward facing rim or to the underside of the dosage unit.

What is claimed is: 
     
         1 . A system for filling of one or more big bags with material, the system comprising:
 a feed pipe having a bottom rim;   an outer pipe, wherein the outer pipe is telescopically attached to the feed pipe, and wherein the outer pipe is movable to a position corresponding to the height of the big bag;   an underlying surface configured to support the bottom of the big bag;   an overlying dosage unit coupled to the feed pipe and configured for storage of the material;   wherein a connection of the feed pipe to the overlying dosage unit has a radial continuous interface surface that is attached to a bracket on the overlying dosage unit;   wherein the feed pipe coupled to the overlying dosage unit is configured to add a measured amount of the material in a vertical stream from the overlying dosage unit via the outer pipe and into the big bag;   wherein the system is configured for retaining a neck of the big bag in an airtight seal around the feed pipe having the telescopically attached outer pipe; and   wherein the system is configured to adjust the distance between the bottom rim of the feed pipe and the overlying dosage unit when changing from a big bag having a first height between the underlying surface and the neck of the big bag to a different height big bag having a second height between the underlying surface and the neck of the big bag.   
     
     
         2 . The system according to  claim 1 , wherein the feed pipe having a bottom rim is a plurality of feed pipes each having a bottom rim and each configured to attach to the outer pipe;
 wherein the plurality of feed pipes comprises at least a first feed pipe of a first length and a second feed pipe of a second length, wherein the first feed pipe is attached to the bracket on the overlying dosage unit, and the first feed pipe is exchangeable with the second feed pipe;   wherein the first feed pipe and the second feed pipe are exchangeably attached to the bracket on the overlying dosage unit; and   wherein the system is configured to adjust the distance between the bottom rim of the feed pipe attached to the bracket on the overlying dosage unit and the overlying dosage unit when changing from a big bag having a first height between the underlying surface and the neck of the big bag to a different height big bag having a second height between the underlying surface and the neck of the big bag by removing the first feed pipe from the bracket on the overlying dosage unit and attaching the second feed pipe to the bracket on the overlying dosage.   
     
     
         3 . The system according to  claim 2 , wherein the feed pipe coupled to the overlying dosage unit is removably attached to the bracket on the overlying dosage unit, and on the bracket there is at least a movable part for securing of the feed pipe coupled to the overlying dosage unit to the bracket. 
     
     
         4 . The system according to  claim 2 , wherein each of the plurality of feed pipes includes a bottom section of a predetermined length along with none, one or several continuous inserted sections between the bottom section and the overlying dosage unit. 
     
     
         5 . The system according to  claim 1 , wherein the feed pipe having a bottom rim comprises several sections, where the length of the feed pipe can be changed by changing the number of intermediate pipe sections between the overlying dosage unit and a bottom section of the feed pipe;
 wherein the system is configured to adjust the distance between the bottom rim of the feed pipe and the overlying dosage unit when changing from a big bag having a first height between the underlying surface and the neck of the big bag to a different height big bag having a second height between the underlying surface and the neck of the big bag by removing or adding one or more of the intermediate pipe sections to the feed pipe.   
     
     
         6 . The system according to  claim 5 , wherein the feed pipe is removably attached to the bracket on the overlying dosage unit, and on the bracket there is at least a movable part for securing of the feed pipe to the bracket. 
     
     
         7 . The system according to  claim 5 , wherein the bottom section of the feed pipe has a predetermined length along with one or more continuous intermediate sections between the bottom section and the overlying dosage unit. 
     
     
         8 . The system according to  claim 1 , wherein movement up and down of the outer pipe during a filling cycle is facilitated by an elevator placed along the feed pipe coupled to the overlying dosage unit, and wherein the elevator runs up to the bracket on the underside of the overlying dosage unit.
