Machine provides multiple sleeving options
can be used to improve container security and increase consumer
Sleever International said its Powersleeve Evolution 4 uses servo-driven technology and up to 12 motion control cards to add a range of sleeves at speeds of up to 24,000 bottles per hour for the single-headed version. Dual-headed systems can add sleeves to up to 48,000 bottles per hour with a movement accuracy of up to a 10th of a millimeter, the company claims. The machine operates through a technique where the floating sheath is opened, rotary synchronized multi-blades then cut, with the sleeves then ejected and attached to pre-positioned packaging. The packaging is moved into position by simple, double, or turned-over scrolling. Containers with diameters of 190, 130, 65 and 16mm can have sleeves added, with heights between 30 and 320mm. Materials including polyvinyl chloride (PVC), polyethylene terephthalate (PET) and thermoplastic elastomer (TPE) with thicknesses between 30 and 120 micrometers are compatible with the machine, the company claims. The Powersleeve has fewer components than existing products and has a smaller footprint, taking up less floor space in the plant, claims Sleever. Components for North American versions are made by Allen Bradley, while European models use Siemens servomotors. Operators can complete format changeovers in under 20 minutes, while maintenance costs are reduced because the diagnostics display of incidents are preventative maintenance reminders, the manufacturer claims. Optional equipment and functions can be added to construct bespoke systems to suit specific needs. These include a synchronized and graduated marking and coding system and various feeders and conveyers. Sleever International manufactures turnkey sleeving solutions, including single- and dual-head shrink-wrappers, steam shrink, infrared and hot air applicators, for customers from the food, drinks and cosmetics markets worldwide.
