A
t Sibeg, official Coca-Cola bottler of Sicily (Italy), ACMI was in charge of the projection, installation and commissioning of a highly flexible bottling line with a filling speed of 60.000 cans per hour. The term flexibility refers to the capability of the line of adapting to the numerous formats along with the possibility of inserting future formats without the need of carrying out any mechanic modifications. At the present moment in time, a total of four different types of cans are handled on the line: 330 ml, 500 ml, 330 ml “sleek” and the small 150 ml “slim”. The typology of the four cans are multiple and account for a total of nine formats, the line however is already predisposed for handling a series of future formats which will lead to a total number of 35 formats. The line is equipped with two shrink wrappers Fenix model, and is capable of forming packs in the following formats: 3x2, 4x3, 4x2 and 6x4. Thanks to a specific system of conveyors, the cans that arrive from the filler may be channeled towards a single shrink wrapper, or first to one machine and then onto another in order to cover all of the desired formats: packs with cans only, cans on trays, groups of more than one pack (over packing). The two shrink wrappers are equipped with an automatic film change over mechanism which does not require operator intervention in any way. In a time lapse of approximately ten seconds, the machine passes from the terminated spool reel to the new reel in a completely automatic manner. This implies great functioning autonomy, as the operator has all the time necessary to substitute the terminated spool with a new spool reel without interfering with the productivity of the machine. In the course of the last biennium ACMI has greatly improved the shrink wrapping oven aspect of energy saving, for this reason ACMI can offer the market a machine at the forefront of technology. The engineers of the shrink wrapping department have orientated their efforts in optimising the resistances of the oven, individuating new material to be used on the pack conveying belt, as well as improving the air flow inside the oven and applying automatic rolling shutters which allow the oven to reach the desired heat in less time maintaining a constant level of

heat even without product presence. All of these features lead to a saving in functioning costs along with further improvement of the quality of the shrink wrapped pack. The palletisation phase is guaranteed by the Twisterbox® layer formation system along with the high level model Faster palletiser that can reach a production speed of 13.000 packs per hour with the configuration of 330 ml “sleek” cans 3x2. The palletisation group is positioned alongside the depalletiser Faster D 200, making it a very compact installation which is rationalised in space. The Twisterbox is a two module system with new concentric closing carbon pliers that guarantee improved speed and agility in handling the product, flexibility of product selection and maximum delicacy when manipulating the product. All of the format changeover operations are commanded by means of a touch screen operators panel and do not require any type of mechanic
intervention. Another innovation presented by ACMI is the rotating ring pallet stretch wrapper model Vortex which mounts an electronic pre-stretching device capable of pre-stretching film to a value of 400%. Thanks to the electronic commanding of all of the parameters, this pre-stretching system may be programmed to adapt to the degree of film pre-stretching at each phase of wrapping optimising the primary material with a cost saving benefit. The specific projection allows elevated wrapping speeds to be reached thus the machine productivity at the current moment is unequaled in the market place. If we add the automatic change-over of the prestretching group as installed on the Sibeg line, the overall result is extraordinary. The stretch wrapper can be equipped with an anti-dust top cover device or a “waterproof” device and can mount spools with a height of 500, 750 and 1000 mm.
