Readers make sense of 2D barcodes
To complement and extend the functionality of its extensive range of barcode readers and vision systems Leuze Mayser has added a series of two-dimensional code readers.
The new VSU 15 system provides label manufacturers with the easiest and most reliable operation available, enabling up to 10 lanes (or channels) to be tracked independently.
Each channel requires separate ultrasonic transmitter and receiver sensors to monitor high-speed label throughput.
During the ultra-fast detection process signals are constantly forwarded to a central evaluation unit where they are analysed before being sent to the labelling machine's master controls.
The new VSU 15 ultrasonic system is also one of the fastest with response times allowing throughput speeds of up to 120m/min with a gap width between labels of only 2mm.
A key feature of the new development is a dynamic teach-in mode that allows the unit to be set to match the sensing needs required for plain, transparent and even metallised labels.
With this contactless system every track is monitored individually and independently from the other tracks, a Leuze patented multiplex process incorporated in the central amplifier module eliminates mutual interference between the ultrasonic sensors.
In developing the new system Leuze has chosen to use an extremely small sensor of just 12mm diameter.
It enables label manufacturers to adopt the new system for detecting a whole range of label sizes, even miniature formats.
Another significant benefit of ultrasonic technology is improved machine reliability since the gap between transmitter and receiver can be set to a much greater distance in comparison with systems that use capacitive technology.
Capacitive systems need a much smaller gap which can easily become clogged should a label peel from its web, build-up of dust and label adhesive may also impede performance, all factors that could result in downtime whilst the sensors are cleaned.
The new VSU 15 from Leuze Mayser overcomes these difficulties.
It also offers the benefit of being able to track labels made in virtually any material - foil, paper, opaque, transparent etc. Request a free brochure from Leuze Mayser ...
