Method for the acoustic control of bottle fill levels

Abstract

The invention relates to a method of controlling the fill level (6) of containers (4). The inventive method involves the reflection of an acoustic signal which is emitted by an acoustic transmitter / receiver device (7), said device being disposed above a single-line flow of containers (4). The method is characterised in that it comprises the following: during an data acquisition step, one or more standard containers (4A) with a known fill level (6) are brought under the acoustic transmitter / receiver device (7); after the emission of acoustic signals, the reflection signal(s) corresponding to the opening and the level (6) of the contents in said standard container (4A) are detected; and, during the subsequent steps for controlling containers (4) with an unknown fill level (6), the deviation(s) in the reflection signals are compared to the stored standard deviation(s), said reflection signals corresponding to the opening and the level (6) of the contents (5) in the container.

Description

technical field [0001] The invention relates to a method of controlling the filling level of a container by reflecting an acoustic signal emitted by an acoustic emission-receiving device placed above a single line of said container. [0002] The invention relates to the field of equipment manufacturing, and aims to ensure the control of the filling state of the content of the sports container. Background technique [0003] Various devices and various methods are known to ensure this control. [0004] In general, these methods are adapted to the nature of the container (bottle, flask, tin box, canister...) as well as the nature of its content (liquid, powder...). [0005] The first solution is by means of an operator responsible for visually controlling the level of content in the container. [0006] For this purpose, the operator must clearly distinguish the level to which the contents of such containers have reached, which makes this method unsuitable for opaque container...

AI Technical Summary

Problems solved by technology

[0013] Also, because of these fluctuations, state-of-the-art methods and apparatus do not allow proper control of the fill level of a container whose contents have a certain degree of fluidity, especially when the container is in motion

[0014] In particular these methods and devices do not adequately ensure control over the fill level of bottles containing liquids, especially wine
