Decentralization by Kollmorgen: efficiency in a compact, modular design<\/p>\n

AKD-N decentralized drives and CDDR motors by Kollmorgen are the core of the innovative OMET Xflex X5, a printing solution with the best returns on investment in terms of market result of narrow web printing of labels and flexible packaging. High quality, and on any materials.
\nMore than 50 years of \u201cpassion for innovation\u201d, curiosity, a desire to learn and explore the world to understand market trends and customer demands, just as it did back in 1963, building its first machines for tissue and labels. OMET is today a group of five companies mainly involved in the design and construction of machines for printing and converting of labels and flexible packaging, and design and construction of machines used to make paper napkins.
\nOMET Printing Division is the group\u2019s company specialized in producing printing machines using combined narrow and medium web technologies, characterized by their operative flexibility, production efficiency on all types of runs, versatility in the use of different materials to be printed and in offering customized configurations to satisfy every customer\u2019s need. After decades of experience and innovation in the printing market, OMET machines combine simplicity of use with low rejection rates, rapid work changes efficiency and reliability over time. But what exactly do OMET machines produce? Labels of all types, plastic films, folding cardboards and special applications.<\/p>\n

The Lecco-based company has won a leading role on the world market over time, and today boasts more than 1,600 installations all over the world. Customers range from small printers to labellers and major multinationals producing and printing flexible packaging.<\/p>\n

How have the paths of OMET and Kollmorgen crossed to mark the start of a highly successful collaboration?<\/strong>
\nIn 2014, OMET visualized the need to design and produce second generation machines. Thus began the search for the most appropriate partner, which became an extremely competitive benchmark, involving various potential suppliers.
\nAt the end of the selection, the Lecco-based company opted for Kollmorgen as its solution provider, not only as being best able to fulfil all requests but also the one able to implement technological innovations: the first development was to be a new machine whose quality of print and flexibility lay somewhere between the mechanical solution of the model X4 and the fully servo-driven X6 series.<\/p>\n

\u201cOMET is a global company and it has chosen a global partner in the form of Kollmorgen\u201d, says Fabio Massari, Senior Sales & Key Account Manager of Kollmorgen Italy.Other important targets included the reduction in the size of the electric cabinet and the volume of cables, modular production of the machines, standardization of the field bus, reduction of components, not to mention important matters like energy saving and print precision.
\nAnother challenge to be overcome in the development of the new machinery came in the form of the maintenance of existing automation software and, if absolutely necessary, a minimum impact of changes in respect of time to market and the safeguarding of R&D costs. Essential characteristics those are fundamental to the project\u2019s success and meeting the demands of customers are ever more meticulous and challenging.
\n\u201cIn addition to offering OMET the guarantee of being able to fully satisfy all needs, Kollmorgen has also introduced a new Direct Drive motor that can eliminate the Gear Marks effect,\u201d – Fabio Massari, Senior Sales & Key Account Manager of Kollmorgen Italy, explains – \u201cand allows for the development of an innovative hybrid\/semi-motorized machine. OMET has also considerably improved use of components relative to drives and safety, eliminating most of the electric cabinet and reducing cable length by around 70%\u201d.
\nThe Motion Control specialist has responded to the need for efficiency, a compact, modular design and safety, by using AKD-N servo drives, Direct Drive Cartridge DDR motors and KSM safety modules.<\/p>\n

Efficient and compact: Direct Drive Cartridge CDDR Servomotors and AKD-N Drives<\/strong><\/h4>\n

In order to reduce or eliminate the mechanical kinematics, Direct Drive Cartridge CDDR servomotors have been used, together with AKD-N decentralized drives. The CDDR motors enable a direct control of movement, without using mechanical transmissions, which resulted in reduction of maintenance, need for spare parts, and safeguards the precision level of the entire machine over time. Motor assembly is fast, involving reduced cogging, with a built-in high-resolution sinusoidal encoder and continuous torque up to 510Nm.<\/p>\n

The AKD-N decentralized servo drive is Kollmorgen\u2019s proposal to design more efficient machines, more simply, which can combine innovative technology and exceptional performance with an extremely compact design. Thanks to the robust structure and protection grade IP67, the AKD-N Kollmorgen decentralized servo drives can be positioned close to the motor, reducing cabling, and thereby reducing the dimensions of the electric cabinet. Plug-in connections, free choice of motor, assembly at the most appropriate point, as well as a wide range of functions: by using decentralized AKD-N servo drives, even complex Motion Control architectures can be developed, based on EtherCAT field buses. The system offers everything needed for the design of new generation machinery, without giving up on simplicity. The hybrid cable with a diameter of just eleven millimeters (patented system) integrates the power supply, safety (STO) and the EtherCAT field bus. The connection to the motor is also simplified with just a single cable for power, brake control and feedback. By Doing so, more than 80% of machine cables are saved.<\/p>\n
