Problems solved by technology

[0005] The disadvantage of this machine concerns the time required to perform the measurements
In addition, the machine has the disadvantage that no additional dimensional measurements can be made other than the weight of the container when it is empty
Although this document is able to measure the volume of the liquid contained inside the bottle, the technique described in this document has the same disadvantages as the patent application US2014 / 211980

Embodiment Construction

[0064] The invention provides a method of determining the capacity of a glass container 1 , such as a bottle, jar or flask (flask) made of glass. From figure 1 As can be seen in , a container 1 is a hollow object, conventionally comprising a bottom 2 from which rises a body 3 extending to a neck 4 terminated by an annular portion 5 defining an opening or mouth , which enables the container to be filled or emptied. The capacity of the container 1 is the volume of liquid contained by the inner surface Sf of the wall of the container when the container is in static equilibrium under the force of gravity with its base standing upright on a horizontal plane (referred to as the mechanical support surface Pp).

[0065] The full capacity of the container 1 corresponds to the volume of liquid that fills the container up to the "ring" plane Pb containing the ring 5 of the container. The nominal capacity Cn of the container 1 corresponds to the volume of liquid that fills the container...

Abstract

The invention relates to a method for ascertaining the capacity of containers (1), wherein a plurality of radiographic images (I) of the container are acquired from different viewing angles by a computer-assisted x-ray tomography apparatus (10). According to the invention, the radiographic images are analyzed in order to: build a computer model (M) of the container from the radiographic images; ascertain the inner surface (Sf) of the computer model of the container; superimpose a fill level plane (Pn) on the computer model of the container parallel to the support plane and at a nominal distance (Hn) from the vertex of the computer model of the container; calculating the inner volume of the computer model of the container, said inner volume being defined by the inner surface (Sf) of the computer model and the fill level plane (Pn), the result of said calculation being the filling capacity (Cn) of the container.

Description

technical field [0001] In a general sense, the invention relates to the technical field of inspecting the dimensions of glass containers, and more particularly to measuring the capacity of said containers. Background technique [0002] The capacity of a container is the minimum volume of liquid that the container holds if the container is filled to the rim or up to a determined height below the surface of the annular portion of the container. Regulatory or administrative requirements make it necessary to know exactly the capacity of the container. The actual capacity of the container must correspond to the capacity marked on the container, which may for example be etched on the container or written on a label affixed to the container. [0003] Variations in the method of manufacturing the container lead to variations in its capacity. For a constant volume of glass, if the volume of the mold increases due to wear, the internal volume of the container will increase. At a co...
