• to measure the axis of bottles
• to control the tolerances
• to sort out faulty containers
• to process the measured values and provide statistics.

Measuring Principle
The mechanical and optical part is similar to the device IDM(C):
The bottles are illuminated through their bottom by some LED- light sources as far as a measuring position is reached, which is determined using a further camera at the bottom. A special lens projects the image of the neck onto the optoelectronic receiver.
It is designed on the base of some CCD-row sensors.
The output signals of these sensors are evaluated in a special microcomputer. It provides the signals to sort out the faulty containers as well as some statistics. The measured values are displayed using a special display unit based on LED-diodes.

Structure
The device permits a simple arrangement on the conveyor belt. The bottle is transported using a bottom belt as well as the finish support belt at their neck. It is easy to maintain and can be combined with other testing systems.

Service and Operation
Particular emphasis was placed on operator convenience: The installation can be done easily and an adjustment is not required even after job changes.

Specifications

• maximum inside diameter of the neck: approximately 30 mm (standard)
• Speed of measurement: up to 300 /min
• Accuracy of measurement: 0.1 mm

• The device works in a contactless manner without wear.
• There is no need of mechanical gauges.
• Any rotation the bottle is not required.
• The device can be used at bottles with a circular cross section as well as at a wide scale of non-circular containers.
• A measured value, not just a test result passed/not passed is provided. This way trends can be detected as soon as possible.

The opening of the bottle is displayed at the 
sensor star. If it is not in the center, 
the bottle axis is perpendicular.
