PETpla.net Insider 10 / 2013

TRADE SHOW PREVIEW 60 PET planet insider Vol. 14 No. 10/13 www.petpla.net Flexible delabelling Sorema, a division of Previero S.r.l., will be exhibiting its patent-pending Delabeller, which is designed to remove sleeve labels in post consumer PET bottle recycling lines. Sorema says that its system can be easily installed in any recycling lines processing between 600 and 12,000kg/h. The company states that it offers low energy consumption along with easy and cost-effective maintenance and spare parts. As well as delabelling, the Sorema technology can also undertake the dry pretreatment of mixed bottles or rigid packaging. The machine can open the materials and sepa- rate contaminants from the surface, as with sleeve labels, and it can be integrated with an aerodynamic separator in order to achieve efficient separation of light and bulky mate- rials. The first Sorema delabelling system was installed early in 2013 in a US recycling plant. www.sorema.it Preform inspection system The Intravis PreWatcher III is the latest release in their line of high- speed pre- form inspec- tion systems. With its space saving design this system can integrate into the production line to perform a comprehensive inspection of each preform for defects. Unlike its predecessor, the PreWatcher III is self-con- tained with a high-tech centrifugal feeding unit already included in the inspection system. By combining both the feeding unit and the inspection system, Intravis is able to fit the system into 8m² of floor space with a maximum height of only 2.5m. The new PreWatcher III can inspect preforms at speeds of up to 72,000ph. To ensure optimal preform presentation to the cameras, the preforms are separated by the VT wheel then picked up by individually rotating vacuum plates. The newly developed top sealing surface inspection with colour camera and bicolour multi- angle lighting detects scratches and notches in the mouth area without being distracted by possible parting lines. While the technology of the predecessor was adapted for the inspection of the injection gate point, the device performs side wall and thread inspection with a total of 6 high-resolution cameras. These cameras take various precise images while the preform is rotating, thus creat- ing a roll out image of the preform surface for the image processing system. The patented background suppres- sion method suppresses the image from the rear side of the preform on translucent preforms, enabling the system to see and evaluate contamination, streaks, scratches, unmelts, oil splashes etc. At the same time the geomet- ric characteristics, as well as the wall thickness, of the preform are being measured. Virtually all thread dimen- sions are measured by the cameras particularly aligned to the thread area. Simultaneously, the cavity numbers are being read, allowing for sorting of preforms by mould cavity numbers or creating cavity-related statistics. This works also for opaque preforms. To complete the inspec- tion, detection of colour deviation in the l*a*b* colour space as well as the transmission in the UV and IR wave- lengths is accomplished using a spectrometer. All refer- ences are taught through a training program. Tolerances for all measured values may be defined via the touch screen of the completely updated and cutting-edge user interface. Preforms that do not meet these requirements are removed from the production process and the remain- ing good preforms are counted. The PreWatcher III cannot only be integrated behind an injection moulding machine but can also be used offline for batch inspection of large preform batches. Intra- vis offers the necessary downstream equipment such as octabin or gaylord tipper, bunker and diverter for the pack- aging of the inspected good preforms. These components are optimally suited for the system and are controlled by the PreWatcher III interface. www.intravis.de Sorema Hall 9 Booth D41, D55 New drying control The Conair Group’s new DC-T TouchView control will be part of a central-drying cell that includes a W300 Carousel Plus desiccant dryer and a four-hopper ResinWorks system, equipped with the Conair Drying Monitor. The DC-T Touch- View dryer control has an eight-inch-diagonal graphical touch-screen interface designed to provide operators with complete system information at a glance, including current and historical temperature data. The ResinWorks system combines multiple hoppers with integral air manifolds, duct- ing and wiring on a single platform. Conair is also exhibiting its FLX loading control, an entry-level plastic-resin-convey- ing system that was recently expanded to handle up to 128 loaders and 40 vacuum conveying pumps. Also networked at the K Show will be a TrueBlend TB-250 gravimetric blender, which offers throughputs of up to 431 kg/h. TrueBlend blenders are available in sizes to a maximum throughput of 5443kg/h. The four hoppers on the blender will be equipped with Access loaders and a Filterless loader. Conair’s new EP1 and EP2 Series of portable chillers will be represented by the EP1A-03 air-cooled model with onboard process fluid pump and tank. Another product making its first appearance at the K Show is an NCF-819 super-tangential granulator, part of a new line of machines with smaller footprints. An ATC dual-spindle coiler, which is designed for winding small, flexible extrusions, will provide an example of the company’s downstream solutions. www.conairgroup.com Conair Hall 10 Booth J59 Intravis Hall 11 Booth A58
