Problems solved by technology

[0003] As a rule, the light-emitting units emit light of the same spectrum and therefore of the same color, which is why the inspection device cannot always obtain reliable inspection results for bottles designed in different colors
Thus, despite the presence of deposited rust, it is possible for a bottle to pass through the inspection unit as a "good" bottle and the downstream rejection unit, even though the bottle in question should actually be separated due to the presence of contamination
If such bottles were to enter a later production process, this would result in unhelpful downtime, since the filled product would be undesirable from a hygienic point of view due to possible exposure to these contaminants.
If such a bottle reaches the consumer, the producer of the product or the manufacturer of the system may further suffer serious losses

Embodiment Construction

[0023] In the different figures, the same parts are always indicated with the same reference numerals and are therefore always described only once. exist figure 1 and image 3 In , the beam paths of the mirror images are indicated using dotted lines and no reference numerals are provided separately.

[0024] figure 1 Shown is an inspection device 1 for monitoring bottles 2 or similar containers. Hereinafter, bottle 2 or similar container is generally designated as bottle 2 . The bottle 2 can be made of transparent or translucent material, preferably glass, or translucent plastic, such as PET. As a few examples, the material or glass of the bottle may eg be blue, green or brown.

[0025] Bottle 2 has a bottom and side walls. The mouth 3 is arranged opposite to the bottom. Using the inspection device 1 , preferably the mouth 3 of the bottle 2 is inspected, preferably after it has been cleaned of eg contaminants, such as scale 4 .

[0026] In this respect, this can also b...

Abstract

The invention relates to an inspection device (1) for monitoring bottles (2) or similar containers, comprising at least one lighting unit (6) and at least one camera (7), wherein the at least one lighting unit (6) is arranged above the bottle (2) to be examined. In order also to be able to examine bottles (2) of different colours, and in order to be able to detect, for example, also rust deposits (4) reliably, according to the invention the lighting unit (6) is designed as a light source circuit board (6), the light sources (8) of which emit light that can be changed at least in colour to a bottle colour determined in the region of a bottle mouth (3), wherein the light sources (8) are arranged in radially spaced light source rings (9), each concentric about a midpoint of the light source circuit board (6), and emitted light is coupled at least partially into the interior of the bottle mouth. By means of LEDs, light modulated in colour at least to the bottle colour is expediently coupled into the inner wall of the bottle mouth (3).

Description

technical field [0001] The invention relates to an inspection device for monitoring bottles or similar containers, comprising at least one lighting unit and at least one camera, wherein the at least one lighting unit is arranged above the bottle to be tested. Furthermore, the present invention also relates to a method for inspecting an empty bottle, particularly a method for inspecting the mouth of a bottle using the inspection device. Background technique [0002] Such bottles or similar containers can be used for liquids, such as beverages. Such containers can be made from transparent or translucent materials, such as glass, or translucent plastics, such as PET. In particular, the glass bottles can have different colours, mentioned only as examples, such as brown and green, but also a blue bottle color. When the bottles or similar containers are empty, preferably after they have been cleaned, they are guided by the conveyor device through the inspection device. It is kn...
