Combined forked sensor

20 November 2020

LEUZE HAS introduced what is reported to be the world's first combined forked sensor. The GSX combines the advantages of light and ultrasonic sensors and is particularly suitable for labeling machines used in the packaging industry.

Affixing labels of various shapes, sizes, and materials on products and packaging by means of a labeling machine is one of the fundamental tasks carried out in the packaging industry. For its precise positioning the label has to be safely and reliably detected – even at high conveyor speeds. This task is performed by forked sensors, which house the transmitter and receiver in a single device and ensure high operational safety. These devices are not only very sensitive, they are also easy to mount and do not require any alignment. Until now, Leuze offered two forked sensor models for this purpose: light and ultrasonics. A new version that combines light and ultrasonics is now available. Leuze is thus adding another world's first to their product
range and rounds off their assortment.

The GSX fork sensor is 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. This increases the machine throughput and avoids downtime. Even labels made of inhomogeneous cavitated BOPP material can be reliably detected through the optical operating principle. The forked sensor is especially well suited for applications in which various types of labels need to be detected. Until now, this often required several different forked sensors. The user saves not only space, but also additional time and costs of installation. The new forked sensor can be quickly and easily set up via the teach button in order to teach the label-carrier combination. Only one universal mounting position is required for all objects.

The GSX features an IO-Link interface, enabling quick and easy configuration. The interface can be used to enable remote teaching, or to lock the buttons, among other things. In addition, recipe management facilitates easy format changeovers when replacing rolls. This means that re-teaching is not necessary when changing rolls to a different label format. The format is changed quickly by selecting the appropriate parameter set for the corresponding label format. This parameter selection is directly carried out on the labeling machine via the HMI. It saves not only setup time, but it also increases the production volume and makes the system more economical.
