However, labels are often not affixed to the bottle around its entire circumference, so the outline of the bottle must also be located where no label is applied

Embodiment Construction

[0051] figure 1 It is a schematic diagram for explaining the present invention. The figure shows only one image acquisition device 6 provided for the bottle 10 to be inspected. figure 1 Radiation devices are not shown. The reference numeral 20 designates a housing which has an overall distinguishable background 12 which is located behind the container 10 in the viewing direction from the image acquisition device 6 . The image acquisition device 6 is here able to monitor the area bounded by the edges R1 and R2.

[0052] Thus, the image capture device 6 simultaneously captures the light-colored area 12a and the dark-colored area 12b of the background 12 . In the control area 14, the light area 12a merges into the dark area 12b. When a dark container is detected, it is contrasted with a light area (especially a white area) 12a of the background 12 behind it. However, if a light-colored container containing light-colored liquid is used, the image acquisition device 6 will als...

Abstract

The invention relates to a device for detecting the outer surface of a container, comprising a radiation device (2) for irradiating light onto a container (10) to be detected, and a conveying device (4) for transferring the container (10) to the radiation device (2) ), and the image acquisition device (6) that collects the image of the container (10) illuminated by the radiation device (2), and the background (12) positioned at the rear of the container (10) relative to the image acquisition device (6), the container ( 10) Can be imaged relative to the background, wherein the background (12) has light areas (12a) and dark areas (12b) in contrast to the light areas (12a).

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for containers. Background technique [0002] In the field of the beverage processing industry, it is often necessary not only to check the filled containers or the containers themselves to be filled, but also the labels affixed to these containers. Thus, the labels which may have some defects such as warping, tearing or the like will be detected by this method. [0003] In this context, inspection devices are known from the prior art, in which the containers to be inspected are conveyed by means of a conveyor belt and inspected from many sides, for example using deflection mirrors. A special problem is encountered here for so-called metal tags, the desired reflections of which are partially canceled (unintentionally) during monitoring by the polarizing filter. [0004] German Patent No. DE 199 04732 A1 discloses a container inspection machine. The containers to be insp...
