PRODUCTS 51 PET planet insider Vol. 15 No. 04/14 www.petpla.net Vision inspection systems and preform domes Several producers have developed new preform dome designs, the common ones being EcoBase with a rocket form or Capello Design with an oval dome design. Each of these preforms can provide weight savings. Further advantages include improved technical characteristics of the bottle or a better matter distribution on the bottle bottom and energy savings, with the preform domes being heated up more quickly. Yet for vision inspection systems these new geometric measurements represent a challenge as the previous inspection algorithms were all based on the conventional ball shape preform domes. Intravis, supplier of preform inspection systems, offers turn-key solutions for customers. Its preform inspection systems Sample Pre- Watcher and PreWatcher III are designed to be updated according to requirements and are able to integrate a new technical drawing of the customer’s preform into the algo- rithm. This enables accurate measurements of the new preform designs. The algorithm ensures the camera does not require re-alignment for every new preform length. Once set up, the software is also able to measure parameters like deviations and contaminations without changing the camera position. Updates for any geometric measurements can be integrated into existing systems in the field. www.intravis.com Past 28,000 Siapi says that it is the first company in the world to manu- facture a two-stage linear blower that can produce more than 28,000 PET bph. The milestone has been passed on Siapi’s range of SDxx two-stage machines (xx indicates the number of cavities, from six to 20, arranged on two parallel presses). The machine’s star loading system sorts the heated preforms into the two presses and a new automation system runs and controls the machine movements that have been designed to be simple make it possible to produce PET containers at very high speeds. The range of two-stage linear blowers extends to eight models. They can be used to produce containers of 9l at a speed of 7,200bph, 4l at 10,600bph, 3l at 12,800bph, 2l at 15,200bph, 1l at 22,800bph, to half litre containers produced at over 28,600bph. It can process necks of up to 45mm and, exceptionally, up to 55mm for the larger 8l and 9l formats. Siapi says that the SDxx range can accommodate up to six of the 10 technology options available for its two-stage linear blowers. The new line extends Siapi’s model range to 36. www.siapi.it
