Title:
瓶の充填レベルの音響制御
Document Type and Number:
Japanese Patent JP2005511436
Kind Code:
A
Abstract:
A method of controlling the fill level of containers involves the reflection of an acoustic signal which is emitted by an acoustic transmitter/receiver device with the device disposed above a single-line flow of containers. In the method, during an data acquisition step, one or more standard containers with a known fill level are brought under the acoustic transmitter/receiver device. After the emission of acoustic signals, the reflection signal(s) corresponding to the opening and the level of the contents in the standard container are detected. During the subsequent steps for controlling containers with an unknown fill level, the deviation(s) in the reflection signals are compared to the stored standard deviation(s), the reflection signals corresponding to the opening and the level of the contents in the container.
