Print-Apply Labeling System

Legi-Air 4050E

Energy-efficient all-rounder for high-speed applications in logistics and manufacturing

Reduced compressed air consumption and low wear
Large selection of applicators, tamps and print modules
Also ideal for cartons of different heights on the conveyor belt
Dispensing cycle rate up to 240 labels/min
Achieves print speeds of up to 400 mm/s
Label size min. 12.5 x 7 mm, max. 160 x 210 mm

The Legi-Air 4050E is a rugged, compact print-apply labeling system with a wide range of options. Thanks to a consistently modular design and more than 1,500 applicator variants, the system can be tailored to your specific application. The many available and very robust applicators support any labeling position and speed. Print engines from all leading manufacturers are available for printing the labels.

The industrial labeling system is designed with no scheduled-wear maintenance parts. Components are replaced only as needed. Only the installed print engine must be serviced in accordance with the respective manufacturer’s specifications.

Legi-Air 4050E comes with an optional n-controller that is OPC UA-compatible (Open Platform Communications United Architecture). This industry 4.0 interface enables advanced connectivity with other devices and the exchange of information that goes beyond simple signals. If required, a bad-tag reject arm is available, which automatically ejects faulty labels and removes them from the conveyor line. A housing specifically designed for integration in harsh production environments with high dust exposure, humidity, and/or low temperatures is also available.

Legi-Air 4050E reduced compressed air consumption

The modulated vacuum reduces compressed air consumption by up to 80 % and integrated sensors permanently measure the pressure. If necessary, the valve technology adjusts. The pneumatics are easily accessible outside the system and the two compressed air circuits are colour-coded for better differentiation. The motorised operation of the winder and unwinder means that the integrated print module wears less, while at the same time the prints are extremely precise.

Whether single-sided, double-sided or corner wrap application - a wide range of applicators and tamps are available for applying labels to products, packaging and pallets. Single-sided pallet labeling with an extra-long dispensing stroke or the labeling of uneven product surfaces is also possible. The Quick Change option is available for a very quick change to a different label size.

Cardboard boxes of varying heights with shipping labels

In combination with our SL applicator—an intrinsically safe servo linear applicator with a consistently lightweight design—Legi-Air 4050E is ideal for high-speed labeling with varying product heights and shapes in logistics. It uses a high-precision distance sensor that determines the distance to the product without contact and then automatically adjusts the applicator's extension path so that the label is always applied at the optimum distance.

The Legi-Air 4050E is easy to operate via the multilingual 7" LCD touch display. Fault diagnostics, productivity, maintenance status and events can also be viewed.

The print & apply labeling system can be combined in all variants with a wide range of print modules from well-known manufacturers. Replacing one print module with another is possible at any time without difficulty. For programming and printing smart labels, an RFID print module is available. This supports all current RFID standards (UHF).
