Embodiment Construction

[0038] figure 1 An embodiment of an inspection method 100 for closure control of containers is shown as a flow chart. The individual method steps 101 to 112 described below are shown.

[0039] Firstly, in step 101 , the closed container is conveyed to an inspection device and the tightness and / or correct seating of the closure is checked with subsequent method steps 102 to 112 . During the inspection, it is conceivable that the individual closed containers are either stopped at a fixed inspection position relative to the optical three-dimensional measuring sensor or are continuously transported forward.

[0040] In a subsequent step 102 the container is at least partially photographed with its closure by means of an optical three-dimensional measuring method. The optical three-dimensional measuring method can be, for example, a stereoscopic three-dimensional measuring method, in which the container with its closure is at least partially photographed from two different image ...

Abstract

The invention relates to an inspection method (100) for the closure control of containers, in particular for bottles, in which the closed containers are conveyed (101) by means of a conveying device and correspondingly applied to the containers by means of an inspection device The tightness and / or correct placement of the closure is checked (102-108), characterized in that, by optical three-dimensional measurement methods, the inspection device at least partially senses (102) the container and its closure and generates (103 ) three-dimensional data, in particular three-dimensional points, three-dimensional line elements and / or three-dimensional area elements, and the three-dimensional data are processed (104‑107) by evaluation means and derived therefrom (108) regarding the tightness of the closure and / or or the conclusion of correct placement.

Description

technical field [0001] The invention relates to an inspection method for closure control of containers having the features of the preamble of option 1, and an inspection device having the features of the preamble of option 12. Background technique [0002] In inspection methods for closure control of containers, closed containers are generally conveyed by a conveying device and checked with an inspection device for the tightness and / or correct seating of the closures applied to the containers. [0003] For example, in known methods, the crown cap is vibrated by means of electromagnetic pulses so that conclusions can be drawn about incorrectly seated crown caps from the vibration behavior. However, this method is only suitable for metal closures. [0004] It is likewise known to use a camera to photograph the closure logo from above or the closure together with the container neck from the side. Closed containers were also photographed simultaneously in the camera image from...
