Secondary packaging machines
SMI designs and manufactures a wide range of fully automatic machines for the secondary packaging of rigid containers such as plastic and glass bottles, jars, cans, cardboard cartons and many others.
The Smiflexi models allow you to package in multiple pack formats using the following materials:
- Shrink film with or without corrugated cardboard pad/tray, with production speeds up to 450 packs per minute (working in three lanes);
- Corrugated cardboard wrap-around boxes or trays with or without film, standard and extra-large sizes, with octagonal or rectangular bases and edges of the same height or different heights, with production speeds up to 80 packs per minute;
- Cardboard sleeves, “OTT” or “NT” versions (bottle neck inside or outside the packaging), with production speeds up to 300 packs per minute.
All Smiflexi automatic packers are equipped with the MotorNet System®, latest generation automation and control system that allows flexible, quick and precise operations thanks to fiber optic wiring and Ethernet and drives with independent axes.
Thanks to MotorNet System®, the machine operator can easily handle all the phases of the packaging process and rapidly switch from one pack format to another according to production requirements.
Format change is simple and fast as it only involves the editing of the machine’s working parameters via the operator panel (POSYC) and, only in some cases, the replacement of a few mechanical parts.
SMI's new ERGON series of SK shrinkwrappers
This new series of machines is based on advanced technical concepts applied to both the design and the manufacturing, which allow to further increase the machines' flexibility and considerably facilitate their management and maintenance operations.
The SK series renovates!
The innovations introduced by SMI on the new ERGON series of SK shrinkwrappers concern each functional section of the machine, with a special consideration for maintenance cost reduction and energy saving.
The new packers of the SK ERGON series stand out for the innovative rounded line of safety guards and for the new grigio Orobie (gray) color.
The rounded shape ensures more room inside the machine, which allows the installation of motors (featuring low energy consumption) on the outside, for an easier access in case of maintenance interventions by the line operator.
Moreover, the safety doors' closing system is equipped with a hydraulic damper, which slows down the closing stage and ensures highest safety standards, since in the final step the door is accompanied smoothly avoiding abrupt slamming.
A new design marked by ergonomics
The ergonomic and functional structure of the frame of the new SK ERGON packers allows the operator to easily carry out all the activities related to the use and maintenance of the system, in full compliance with highest safety standards.
There is no contact between the moving components and the packaged product because the threaded shafts, on which the guide and chain adjusters slide, are housed in a safe environment that protects them from dirt and dust.
Furthermore, SMI shrinkwrappers do not use geared motors as they are driven by brushless motors (controlled by digital servo-drives), which are connected directly to the drive shafts, with the consequent advantage of reducing energy consumption, noise levels and maintenance.
New heat-shrinking tunnel
The technological innovation applied to the new SK ERGON has also affected the fundamental element of a shrinkwrapper: the heat-shrinking tunnel.
SMI heat-shrinking tunnels boast cutting-edge technical solutions that allow reducing energy consumption and ensure the utmost environmental compatibility of the processes.
Thanks to the precise analysis of thermodynamic phenomena generated by the shrink process, SMI tunnel distributes hot air flows in an efficient and homogeneous way on the pack, thus ensuring its excellent quality at the end of the process.
Special fans, positioned in the tunnel at regular intervals, fix the pack's shape and stiffness. At the outfeed, an optional belt joins the tunnel up with conveyor belts; the junction is ventilated to ensure the right thermal transition of the pack.
The ergonomic frame of the shrink tunnel lets the operator work easily during maintenance and cleaning operations.
A special meter placed externally ensures an immediate and detailed online monitoring of energy consumption, also available on the machine control panel.
The distribution board of the tunnel features a double forced ventilation system.
