ALritma is a high performance self-adhesive label applicator designed to be integrated into packaging lines where production speed and reliability are primary needs. ALritma labellers are based on an innovative mechanical structure which can match great sturdiness with versatility.
It is available in three versions, S, M and L, for label widths up to 100, 200 and 300 mm. respectively. The label driving group has been designed to exploit the stepper motor features to the full, by guaranteeing an accurate label positioning even at the highest production speeds; the side access has made the web threading easier.
The label applicator is controlled by a powerful microprocessor, with a display "Touch Screen", which allow for the running of advanced functions by relieving the operator from complicated mechanical adjustments and considerably speeding up the format changeovers.
In more detail, the following functions are available:
pre-dispensing adjustment in tenths of mm
speed adjustment by 0.1 m/min.
labelling delay adjustment in mm.
acceleration/deceleration ramp adjustment
storing of different labelling formats
automatic recovery of a missing labels
progressive and regressive pieces counter
automatic removal of double detection
shift register between product sensor and label positioning point
end-of-roll alarm and web break alarm
contact for connection to other systems
In addition to the sophisticated standard devices, ALritma labellers can be equipped with an
array of options which increase its range and performance:
supplementary unwind unit
powered unwind unit for larger reel up to 400 mm
hot foil printing unit
label sensor for transparent material labels
pneumatic and air-blow applicators
checking device for near end of reel
checking device for performed product labeling
no-stop electronic device for sequentially-placed applicators
control of automatic speed adjustment, via encoder
pre-set for serial Interface connection to a PC
The characteristic feature of ALritmaT labellers are that it can integrate all SATO thermal transfer printing systems (and also DATAMAX and ZEBRA) that allow to print in real time batches, sell-by dates, bar codes, progressive numbering and graphics, etc., as well as to identify and decorate products by opening up an extremely wide range of options.
Finally, where linear speeds, production rates, autonomy and labelling precision are peculiar elements for functioning of systems with high investment value it is available a model particularly performing version of the ALritma (model of proved reliability during the 5 years of its spread on the world market) called ALritmaXtra: is stronger and harder in the structure than the starting model; and it is also equipped with a 350 mm diameter unwind unit and an oversized and motorised rewinder unit for the silicon paper, to get more working autonomy: crucial characteristic, this, above all when at 60 m/min (80 options) linear speeds and 800 pieces/min cruising rate, the unwind exhaustion happens quickly. In extreme cases it´s possible to resort also to a - no-stop - device between two labelling machines in cascade connection, that allows the unwind change without stopping the line. The ALritmaXtra machine body is IP55 and the control box is anti water INOX.
ALRITMA X is equipped with an enlarged 400 mm diameter unwind unit and an oversized rewinder unit for the silicon paper, for increased range and reduced downtime. It can reach label feed speed of up to 40 m/min (thanks to a new, powerful stepper motor driver board) and is available for label widths of 100 and 200 mm.
The advanced version of the ALritma X is fitted with an HP (high performance) kit made up of a motorized rewinder unit for the silicon paper as well as an innovative “push-pull” label web drive system. In this configuration the unit can reach 90 m/min at a cruising rate of 900 labels/min., with high positioning accuracy even when the product transit speed varies. This version is particularly suited to huge workloads, such as on rotary labellers, especially in applications using printers/markers with their checking devices.
The ALritma X includes numerous technological innovations, the result of ALTECH experience in manufacturing over 5,000 ALritma units.
Among these are:
the facilitated paper insertion system (with cantilevered rollers);
the compact size (albeit with a 400 mm unwind unit), the double-effect pre-unwinding system;
the push-pull drive system;
the compact rewinder unit for the silicon paper with brushless motor and gearmotor buried in the unwind plate;
the silicone paper removal system integrated into the paper driving disc;
the checking device for near end-of-reel and rewinder full, with new ultrasound sensors;
the reel blocking system through an expansion mandrel;
the IP55 rated machine body;
and the compact control box with a touch screen interface.
Thanks to its professional resources, ALTECH can provide a qualified technical advisory service for any labelling problem, developing designs for complete plants and offering guaranteed maintenance and assistance for all the installations.
