Abstract
The invention relates to a device and a method for checking the leak tightness of deformable containers. The device comprises a probe that can be brought in contact with a container in a probing motion, a drive unit for the probe, and a measuring apparatus coupled to the drive unit and/or the probe for determining the container leak tightness by evaluating the probing motion. For said device, according to this disclosure, a sensor element adapted to detect motion of the sensor element is arranged on the probe, and that the measuring apparatus coupled to the sensor element is designed to record a time curve of the probing motion.
Claims14
A device for checking the leak tightness of containers under internal pressure, comprising:
- a probe that can be brought into contact with a deformable container in a probing movement;
- a drive unit for the probe and a measuring device coupled to the drive unit and/or the probe for determining the container leak tightness by evaluating the probing movement;
- a sensor element arranged on the probe and adapted for the detection of a movement of the probe;
- and
- a processor configured to, during operation of the device, switch off or decouple the drive unit from the probe after an initial drive phase, whereby at least during the contact of the probe with the container, the probe is directed against the container without any driving forces, whereby the probe is freely flying before contacting the container;
- wherein the measuring device coupled to the sensor element is configured to detect a course of the probing movement over time.
