Foreign bottle detection
An additional module can be installed in front of the machine for detecting foreign containers, which have a different contour, height, diameter, and colour than the product container. Here, the camera takes an image of the lateral contour. Thus, foreign containers can be determined and rejected systematically. This inspection module also provides the possibility of scuffing and colour detection. |
Base inspection /inner sidewall inspection
The camera takes an image of the container base, which is evenly illuminated by a flash lamp. The automatic, electronic exposure control also guarantees a uniform image brightness, and continuously high image quality with containers of different transparencies. Worn PET containers can be detected through stress cracks on their bases. A second camera inspects the inner sidewall through the container opening using this illumination unit. This is especially important for large-surface permanent labels (ACL). |
Sealing surface inspection
The sealing surface is illuminated from above via a dome-shaped array of LEDs. The system processes glass and PET containers with neck finishes for crowns, screw caps, or other closures, and it registers even the smallest chips in the sealing surface area. Due to the system ' s high sensitivity, scuffing of the sealing surface and certain cracks in the glass can be detected. With PET containers, the carrier ring can be monitored, and the neck can be inspected for bent or deformation (ovality). |

Residual liquid inspection
The detection of residual liquid in containers is by means of two independently operating systems : A broadband infrared system detects all liquids, e.g. oil residues, whereas a high frequency technology guarateens maximum security. For an optimum protection of the bottling line, a separate residual liquid detection unit at the converyor (in front of the filler) is reecommended .

Sidewall inspection
In two inspection stations, high-resolution CCD cameras inspect the bottle wall all-around (360 0 ) . Several images of each camera enable large overlapping areas between the image sections. The LED wall illumination provides an even light distribution, and has a long shelf life, low power consumption , and very little warmth creation.
With an additional set of filters, the film residues can be securely detected. With glass bottles, scuffing can be detected as of a defined width, and large-surface cracks can be registered in the sidewall area. |
Vario stations
The vario stations, which are prepared by standard, inspect the lateral neck finish, detect base cracks, or perform a full thread inspection, depending on the customer's requirements.
The lateral neck finish inspection checks the mouth piece of the crown bottles for contamination , cracks, and chips below the sealing surface. The base illumination and base camera are positioned below the container base for detection container base chippings. The full thread inspection takes a spiral image of the screw thread with special optics. Thus, the interruption lengths of damages can be measured, or coarseness can be accurately detected and evaluated. |
Lateral neck finish inspection for PET bottles
A lateral neck finish inspection unit for PET bottles can be fitted at the machine discharge.
All sides of the neck finish are inspected by a camera and an optical system. The lateral neck finish area including
the neck ring and the vent slots is inspected for contamination and damage.
