With over 32,000 visitors from over 24 countries, Expopack, held in Mexico City, is the gateway to the entire South American packaging market and transformation industry. Over 850 exhibitors will be meeting up in the Mexican metropolis from 24th to 27th June to show off their best packaging and food & beverage processing machines. Among them, of course, will be the SACMI Group, exhibiting on stand 3402.
Taking centre-stage will be the advanced Sacmi-developed vision systems, which will be presented to potential customers by Sacmi Mexico personnel and the Group’s sales force. More specifically, Sacmi will be exhibiting a PVS-2, an innovative machine developed by the SACMI Imola automation and control systems division.
The machine can detect any kind of defect on preforms and also interacts with the line to block any production errors immediately. The main advantage of the PVS-2 model – compared to the tried and tested PVS-1 – lies in the possibility of being able to install it in line, next to the press. Able to analyse up to 2000 preforms per hour, it uses a sampling system that withdraws preforms at set intervals and returns them to the production cycle where free from defects. If, instead, they are faulty, a warning is triggered so the operator can pause production.
All PVS models can manage, with great flexibility, various preform formats and diameters. Able to be connected to any mould controlled by just about any model of injection machine, PVS vision systems detect a wide range of defects, from contamination and dirt to crystalline formations, from container deformity to dimples and holes at the injection point, from bubbles and opacity to colour drift. The PVS-2 can be used downstream from the press or configured as a standalone quality control lab machine.
SACMI Labelling S.p.A. will be presenting the Opera 200 Roll Fed, a continuous roll-fed labelling machine with a pressurisation system for empty bottles with partial or wrap-around labelling that provides output rates of up to 36,000 bph.
It features two independent roll supports, complete with film tension control; during unwinding the film is guided by an automatic, continuous vertical position correction system. The film drive roller is controlled by an independent servomotor that corrects the film feed rate on the basis of the effective position of the label step. Cutting, instead, occurs on a roller equipped with a rotating cutter that acts against a static blade. A suction roller then transfers the labels to the bottle without any slippage. Hot melt adhesive is then applied on the initial tract of label and overlapping flap by a steel glue roller that reduces glue consumption.
The labelling process is, then, simpler because it no longer depends on the label material or the characteristics of the transfer roller.
Like all SACMI Labelling machines, the Opera 200 has been designed to provide the operator with trouble-free access to main parts and make cleaning and maintenance as easy as possible; it can also be equipped with automatic roll splicing to allow continuous operation.
