Detection of labels and splices on a material web

Ultrasonic sensing evaluates the passage of sound through the material between the emitter and receiver. On labelling equipment, it helps distinguish the label area on the carrier web; when processing rolls, a suitable version can detect splices and glued sections. Selection starts with what change the sensor is to report.

Example assembly for label detection: Pepperl+Fuchs ULB-18GM50-255-2E3.

ULB for labels, UGB for web splices

What to compare before ordering

Prepare a sample of the label, carrier or splice and data on the highest web speed. Compare the smallest gap, the position of the web in the measuring space and the sensor response time. Printing and colour are not the same limitation for ultrasonic evaluation as for the optical principle; verify the usability of the specific combination of layers on a sample.

When wiring, verify the PNP or NPN output, contact logic, pulse length and Teach-in procedure. With a split assembly, maintain the relative position of the heads and the compatibility of its parts.

Can a label sensor also be used for roll splices?

There are separate ULB and UGB series in the range for the two tasks. When changing the application, compare the evaluated states and the relevant manual.

Manufacturer's documentation: ULB – etikety and UGB – web splices.

Selection questions

What should be sent for assessment of a label sensor?

A label sample together with the carrier web, the smallest gap between labels and the highest line speed. The whole combination of layers, the web guidance and the required output to the control system are important.

How to choose between the ULB and UGB series?

Choose ULB for detecting labels on a carrier, UGB for detecting splices in a material web. For both series, verify the specific material, response and electrical design according to the complete order code.

Selection and technical consultation
