Empty bottle inspector

Bottle separation
A motor-driven, light-barrier controlled star wheel ensures an optimum and exact form of bottle separation at the inlet.

Servo drive
Special conveyor belt with synchronous running provide exact positioning in front of the individual inspection stations. The conveyor belt softgrip protects the containers to the best possible extent.

Machine head
Simple, motor-driven height adjustability from a precision counter for every bottle and container size.

Detection systems 
Deployed here are the latest high-resolution CMOS cameras with gigabit/Ethernet USB 3.0 interfaces. They create an optimum detection with a band width in excess of 100 Mbyte/s and an 8 bit colour depth.

Image processing
The tailored hardware and software of the machine-internal, fanless compact industrial PCs ensure a maximum quality of detection.

Inspection stations
The mouth, sealing surface, base and residual liquid inspection stations installed in the machine head are flexibly adapted to requirements and are both activatable and disengageable.

360° side wall inspection
A special Fresnel lens station at the bottle inlet and outlet. By rotating the bottle by 90° in the belt station and the telecentric parallel see-through, cracks, impact marks, scuffing, paper residue and film are reliably detected all round the bottle with a 360° overlap.

Base inspection
An anti-reflection/shadow bottom-up is used for an all-over base inspection. This permits low-density foreign matter, such as foils and glass splinters, to be detected.

Thread detection
The XPlorer² thread detector examines screw tops over the entire thread geometry, whether there is only one thread or several. Various mirrors are used to process the thread pitches and to examine any critical signs of wear or damage.

Sealing surface and mouth inspection
The entire mouth is imaged and analysed as to faults. Nicks, flaking, damage, stress cracks, rust stains and deposits are automatically registered.

Faulty bottle ejection
The specification determines whether a KS pusher or a KS linear ejector gently ejects faulty bottles out of the production process.

Control panel
The touch screen has a self-explanatory user interface, an unlimited sorter pre-selection and a vision/traceability function. It can be flexibly installed at the machine inlet or outlet.
