This year LITA celebrates 50 years of activity thus priding itself on a further significant achievement. The reaching of this milestone demonstrates the validity of the industrial policy set and is also satisfying for all those customers who have chosen LITA over the years. The quality of execution of the machinery, the care with which it is designed and especially its reliability are an excellent guarantee for those needing to make an important investment.
For example LITA is able to boast a large number of machines installed more than 30 years ago and still operating satisfactorily. The staff employed by LITA for the design and execution stages are highly qualified and constantly committed to applying the most modern technologies in search of innovative solutions aimed at making the systems more efficient and long lasting. The streamlined structure with which the production system is organised allows the company to maintain a high degree of flexibility to be able to easily adapt its models to its customers’ needs. The market for consumable products is
undoubtedly becoming more demanding and consequently production facilities must be able to adapt quickly, even and especially in the case of installations already in place. The design of each model is fully developed with latest generation CAD programs in 3D environment and is being constantly developed and improved in order to improve the product, always focussing on maintaining a competitive sale price. The range of palletising and de-palletising systems offered by LITA covers the needs of the most diverse industrial sectors of production and the relative requirements of automation.
Thanks to the 18 models of machines available and their extreme flexibility of configuration, the right solution is always close at hand. The fields of application of LITA machines are very extensive. The main ones are the food and drinks sectors, as well as the chemicals, cosmetics and pharmaceuticals industries. In production there are models suitable for low speed lines, generally used for high value-added products, and others that meet the high production capacities of mass consumption products.
LITA systems are found installed and working at the plants of internationally renowned clients throughout the world, although there is a greater presence in Europe. Currently nearly 80% of sales are intended for the foreign market. In particular the United Kingdom and France are the major references.
PASTA IN PALLET-BOX
In terms of innovation, LITA always operates at the highest levels and the particular attention to researching solutions that meet the specific needs of customers is once again demonstrated with the realisation of a palletising system for bags of pasta in pallet-box.
The system installed at a major Turin manufacturer was specifically designed to handle 5 kg bags of pasta, primarily intended for the catering and associated sectors in a variety of formats with a production speed of 25 bags/minute using an anthropomorphic robot. In order to ensure adequate protection during transportation, this type of product is normally inserted into pallet-boxes, that is, into large trays with sides of height 700mm, resting on pallets.
In order to be able to fit the packages into the container at the required rate, a special pick-up system was designed to manipulate 2 stacked bags per cycle. To obtain this arrangement of the products at the pick-up point, the system is equipped with a 2 level conveyor system. A box centring device is also provided to ensure precise positioning during the filling stages.
JOLLY ROBOT PALLETISER
The palletisation robot JOLLY model is a cartesian axis portal with 4 degrees of freedom. The mechanics entirely in aluminium, combined with slides on precision linear guides make the system extremely agile, fast, and accurate. The vertical rod is built with a set of telescopic slides enabling significant movement while minimising bulk height. The system also remains rigid with total extension, ensuring excellent positioning accuracy.
In the basic version, movements are driven by asynchronous motors controlled by vector inverters, with controlled axes and positioning encoders. There are several pick-up devices, both with suction and with mechanical gripper, possibly also equipped for interlayer and empty pallet pick up.
Graphic and intuitive operator interface, with the reporting of faults and displaying of machine functions. Ability to program simply new formats from the panel supplied. Adjustments to the format change are automatic.
Machine configurations executable according to requirements, for service on single lines or with multiple pallet positions. Production speeds of up to 10 cycles/minute, with the ability to perform multiple pick-ups depending on the processing format. In the version, created with synchronous brushless motors managed by digital drives, it reaches 15 cycles/minute.
