SK 1202HS “High speed”
It is the model specifically designed for high-speed productions, up to 270 packs per minute in double lane. The new SK 1202HS is equipped with a newly conceived shrinking tunnel, using an innovative system to manage air flows which lets hot air evenly distribute on all sides of the pack. This system allows getting superior quality packages from the aesthetic point of view.
The film-cutting system is equipped with brushless motors and assures higher efficiency and precision in the machine operations. The automatic format change adjustment device at the machine infeed considerably simplifies all the operations to be executed when a format change takes place, since it dramatically reduces the operator’s manual activity and, consequently, the probability of errors and damages.
The SK “HS” series also features a highly ergonomic “pit-type” blank magazine, whose capacity can be expanded by additional modules, which can be loaded automatically through robots.

1In the machine infeed zone, a group of guides accurately lines up the loose containers carried by a conveyor belt featuring low-friction chains made of thermoplastic material. In the pack formation zone, the containers are clustered in the required format through electronically synchronized pins, operating in continuous motion.
2In P and T models, a corrugated cardboard pad or blank is picked from the blanks magazine by a rotary picker composed of a group of vacuum suckers. The pad or the blank moves along the blank climb and places itself underneath the group of products in transit with the long side leading.
3In the tray former, special mechanical devices fold the blank’s front and rear flaps. The side flaps are sprayed with hot melt glue and then folded, thus forming the tray.
4The unwinding of the film reels, placed in the lower part of the machine, is controlled by a dedicated device ensuring the film precise and constant tensioning. Before the pack enters the shrinking tunnel, the film is wrapped around the container batch and overlapped at the base of the pack.
The innovative “Easy-Load” system allows the automatic loading of the cardboard blanks magazine and features considerable advantages from an operating and functional point of view; in fact, the operator can easily load the cardboard blanks, stacked horizontally in uniform groups, because the feeding belt of the cardboard blanks magazine is positioned at the same working height as the packer's infeed belt, rather than under it.
More in detail, the new system patented by SMI is made up of a series of conveyor belts, fitted with motorized mats, which feed the packer's cardboard blanks magazine; the cardboard blank stacks are carried on these belts up to the area in which they are translated and then continue up to the collection system at case/shrink packer infeed.
Thanks to specific sensors, the layout and feed of the cardboard blanks on the conveyor belts fitted with the motorized mats and their loading into the packer's magazine is, in fact, fully automated.
Therefore, the innovative solution devised by SMI eliminates the disadvantages related to the traditional loading of the cardboard blanks magazine, which force the operator to bend his/her body continuously to place the blanks in the bottom part of the machine.
The technology used in the "Easy-Load" magazine also features the great advantage of ensuring fluid and constant picking operations with a wide range of cardboard blanks having a thickness between 0.5 mm and 5 mm.
The TS stacks on two or more layers clusters of plastic, metal , cardboard or glass containers both clustered in cardboard trays or pad and loose (this latter solution solely for fit-in type cans). This device can be installed on all SMI packers, with the exception of MP series.
It consists of an electronic stacking device operating in continuous motion, which achieves an output rate up to 60 packs per minute according to the machine model and to the product handled.
Pack collations can vary according to the container shape, capacity and size; in general, the most requested collations are: 4x3 and 6x4. It is available both for single and for double lane production.
After coming out of the trayformer, two or more packs are stacked by means of a Cartesian coordinate system.
Before the pack enters the shrinking tunnel, the film is wrapped around the products and overlapped at the base of the pack.
The Easy-Open system can be installed both on the SK shrinkwrappers and on the CM combined packers. It consists of a device piercing the film during the cutting operation, in order to create the required mark.
It can pierce two types of marks, “I”-shaped and “H”-shaped, and is available both for single and double lane production. Thanks to the Easy Open system, the customer’s level of satisfaction is definitely improved, because of the easier opening of the pack.
Moreover, this application does not require any specific packaging materials and, therefore, allows to obtain eye-catching packs without additional costs.
SMI customers can now upgrade their SK and CM packers with an innovative film welding device. The “film welding device by heated blade” joins the edge of the film reel about to end with the beginning of the new reel while the machine is running, with no need to stop production. The machine slows down and the film (printed or neutral with reference mark) is automatically joined; the machine is immediately back to running at full pace.
The new system allows dramatic cuts on energy and maintenance costs compared to traditional hot sealing method, as there are no more sealing rollers to be kept at a consistent temperature. The sealing precision of printed film or neutral film with reference mark is higher, with +/-10mm margin from the reference mark. The "film welding device by heated blade" can handle also no-collant film.
