The EyeBeverage Scratch Inspector inspects the abrasion (scuffing) of glass bottles during production. Bottles which exceed the threshold are discharged.
Detection of Scuffing-rings
Because a real problem of glass bottles is the so called “scuffing-rings”. Those milky-white rings occur on the edges of the bottles, when they clash together on the conveyor belt. In the progress micro scratches occur on the surface, which do no harm the function of the bottle, but do not look aesthetically appealing.
The cycle time of a glass bottle is defined through different characteristics. First the bottles are automatically inspected. The criteria for the sorting are:
- damage on the mouth piece
- not cleanable contamination (e.g. foreign material)
- the degree of scratching (scuffing; scratches, scrub marks, other surface damage)
The Scratch Inspector inspects the scuffing on the edge of the bottle. A signal for discharge is issued, as soon as the bottle exceeds the degree of scuffing.
Integration into a Tracker-System
The system is available as compact unit, with all components for a fast integration into a machine. It can be integrated into an existing tracker system. The interface adaption is very easy and already adjusted to the different machines.
If there is still no tracker board integrated, an EyeTrack board can be used. It was especially developed to monitor the delay between the inspection signal and the discharger and to guarantee that in the channel of the good parts are only inspected products. The system can either be connected to an encoder or a facility trigger and issue either an inspectin trigger or the discharger trigger.
The delay between inspection position and the discharge is set on the user interface.
