Abstract
Abstract A method for measuring out and filling of pourable goods into packaging containers and an apparatus which functions according to this method are proposed. In order to attain high filling output especially in the case of voluminous goods, or goods having a low specific weight, a feeding apparatus for the packaging containers is assigned one after another a plurality of weighing devices each having one dispensing device. The weight values of the first partial quantities measured out and filled into the packaging containers are added up in a computer (S I-S II, ΣI+II-ΣI+II+III), which directs the last dispensing device to furnish the remaining deficient quantity.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
134 words
A method for filling packaging containers with a quantity of pourable goods, measured out by weight, comprising the steps of: sequentially measuring out of a plurality of first partial quantities belonging to one package unit one after another; weighing, one after another, of the measured out first partial quantities belonging to one package unit; storing and summing up the weight values of the first partial quantities belonging to one package unit in a computer; sequentially filling of the first partial quantities belonging to one package unit into a container after being weighed; comparing the summed-up weight values of the weighed partial quantities belonging to one package unit with a set-point value; and measuring out at least one other partial quantity equal to the ascertained missing weight value and the filling thereof into the container.
Claim 2
Independent Claim
134 words
A method for filling packaging containers with a quantity of pourable goods, measured out by weight, comprising the steps of: sequentially measuring out of a plurality of first partial quantities belonging to one package unit one after another; weighing, one after another, of the measured out first partial quantities belonging to one package unit; storing and summing up the weight values of the first partial quantities belonging to one package unit in a computer; sequentially filling of the first partial quantities belonging to one package unit into a container after being weighed; comparing the summed-up weight values of the weighed partial quantities belonging to one package unit with a set-point value; and measuring out at least one other partial quantity equal to the ascertained missing weight value and the filling thereof into the container.
Claim 3
Dependent Claim
37 words
A method as defined by claim 1, wherein the filled total quantity is made up of at least three partial quantities measured out and filled one after another, with the weight of each becoming smaller each time.
Claim 4
Dependent Claim
43 words
A method as defined by claim 1 or 2, wherein in the weight values of the partial quantities are fed the form of digital signals into a multistage computer, which after summing the signals controls the measuring out of the last partial quantity.
Claim 5
Dependent Claim
45 words
A method as defined by claim 1, wherein one signal at a particular time pertaining to a predetermined total quantity is added to a signal already present in a summing memory and then is passed along to a next subsequent summing memory of the computer.
