Industrial Weighing

The invention consists in a machine for checking weight accuracy, and in other machines for industrial weighing, which use two or more scales instead of only one. The scales must be similar and loaded consecutively with the mass to be checked.

The scales are equipped with a device adapted to calculate the detected weight on an average. This average weight value has regularly proven to be statistically more precise than values detected by only one scale: this is the industrial invention.

The invention consists in providing the machines which are already equipped with weighing systems (static and dynamic machines for weight control,weight selecting machines, weight filling machines, weight distributing machines, etc) of several scales arranged in sequence, so that the same quantity is successively weighed by each scale; the weight values thus obtained are then averaged by means of a suitable computer which supplies the result of these averages for each weighed mass.

To give an example, reference is made to the machines for the automatic weight control referred to by the metric law as "weight selecting machines".

Such machines are mainly composed of: a conveyor spacer of the objects to be weighed, of a scale, of an electronic system for detection and comparison with one or more acceptable preset values and of an output conveyor equipped with or without a device used for the separation of non-accepted objects.
