The packaging industry uses labels of various formats, sizes, materials, and textures that are affixed to products and packaging by means of labelling machines.
The accuracy of the label placement is important in this process. Label placement describes the precise positioning of the label on the product or packaging, even at high conveyor speeds.
To achieve this kind of high label placement accuracy, it is critical that the labels are reliably detected. This is where fork sensors come in.
Fork sensors combine transmitter and receiver into a single device and therefore feature high operational reliability. They are characterized by simple mounting without the need for alignment as well as high sensitivity.
The Leuze GSX Fork Sensors are the world’s first sensor of its kind and combines the two detection methods of ultrasonics and light in a single housing. It brings together the advantages of both principles and can be used very flexibly.
It reliably, quickly, and precisely detects a wide range of labels, regardless of their material and surface characteristics.
Even labels made of inhomogeneous cavitated BOPP material can be reliably detected through the optical operating principle.
The fork sensor is thus especially suitable for applications where a wide range of labels need to be detected, which, in the past, frequently required the use of multiple different sensors.
Advantages for you
The reliable detection of labels of a wide range of materials and textures ensures high machine throughputs and prevents downtime.
No reconfiguring of the sensor is required when switching label rolls. The shorter setup times result in higher production volumes.
Quick and easy setup of the sensor through simply teaching in of the label/carrier combination via the teach button. Only one mounting position is required for all objects.
Reliable operation even in case of contamination and variations in terms of label/carrier materials through automatic readjustment of the switching threshold.
IO-Link for easy integration of additional functions in the machine control, e.g., easy format change for roll replacement through recipe management, remote teaching of the sensor, or locking of the buttons.
