Abstract
An inspection device and an inspection method for detecting foreign bodies in a filled container, and having at least one inspection camera, a transport device for the at least section-by-section linear transport of the container and at least one vibration device for vibrating the container, where foreign bodies in the containers can be set in motion without complicated acceleration and retarding of the container and the movements can be registered and compared as single images by the inspection cameras even with a stationary camera position. The construction of the device is less space-consuming and less complicated than for machines of the rotary type and the detection of foreign bodies is more reliable than with conventional machines of the linear type.
Claims13
Inspection device for detecting foreign bodies present in a filled container in a vicinity of a container bottom, comprising:
- a) at least one inspection camera arranged such that it can take dark-field images of the container bottom from below;
- b) a transport device for the at least section-by-section linear transport of the container;
- c) at least one vibration device for vibrating the container and setting the foreign bodies in motion;
- and
- d) at least one illumination device located below the transport device and below the vibration device, wherein the illumination device irradiates the container sideways such that the foreign bodies in the vicinity of the container bottom are irradiated.
Inspection method for the detection of foreign bodies present in a filled container in a vicinity of a container bottom, comprising:
- a) linear transporting the container at least section-by-section with a transport device;
- b) vibrating the container side wall with a vibration device to set foreign bodies into motion located on the container bottom;
- c) irradiating the container sideways with an illumination device located below the transport device and below the vibration device such that the foreign bodies in the vicinity of the container bottom are irradiated;
- and
- d) acquiring light which has been deflected on the foreign bodies and taking dark-field images of the container bottom from below.
