PDF Download, 0,50 MB 0,50 MB Krones Cantronic Quality control for beverage cans

High production output with comprehensive can inspection

It is easy to lose track if every second 33 cans pass by rapidly. Not with Cantronic, because this can inspector detects even smallest contaminations at this speed. The cans and the machine just profit alike from this speed: The cans, because they reach the point of sale at best quality, the machine, because malfunctions caused by faulty cans are excluded.
You can rely on the product quality and line efficiency always being at an optimum state. Because trust is good, control is better, the Cantronic constantly monitors itself.

Your benefitsOpenClose

  • Precise quality control

    The high-resolution basic camera detects even smallest contaminations and irregularities. With the patented auxiliary camera you can even detect creases and dirt in the neck area which are very hard to find.

  • High line efficiency

    Damaged or deformed cans are significant safety risks for the bottling line which can lead to machine standstills and machine damages. Cantronic sorts out all “risky” cans thus increasing the overall line efficiency by approximately 5 %.

  • High degree of operational

    The Cantronic rejects fallen-over containers automatically and monitors itself continuously. Thus malfunctions can be prevented right from the start.

  • Protected access

    Transponders protect the device from undesired access.

  • Uniform operating concept

    All Krones machines are equipped with a uniform operating concept for maximum user friendliness.

  • Remote diagnostics and remote service

    The remote service provides specialist consultancy and service around the clock. If required, a Krones technician can access your inspector via a secured data line. This way, parameter settings, software updates and malfunction analyses can be performed cost-efficiently and quickly.

Figures, data, facts - Method of operationOpenClose

Method of operation

 The can interior – base, wall and flange – are inspected by a highresolution CCD camera. An optional special camera allows for the detection of wrinkles and dirt in the neck area of 202-type cans. The sensitivity of the inspection unit can be variably adjusted to any can type. Faulty containers are rejected immediately and conveyed to a collecting bin via pusher.
