Abstract

The present invention relates to a System for automatic evaluation of preforms, characterized in that it provides an inspection system, to which preforms are supplied, a weighting system, downward the inspection system, and a selection system, downward the weighting system, said preforms being transferred from the inspection system to the weighting system with a set orientation.

Claims

1. System for automatic evaluation of preforms, said system providing an inspection system, to which preforms are supplied, a weighting system, downward the inspection system, and a selection system, downward the weighting system, said preforms being transferred from the inspection system to the weighting system with a set orientation, said system being characterized in that a support is provided downward the system for transferring performs, substantially an elongated V shaped support, having an inner groove on correspondence of V vertex, permitting contacting perform tip and stabilizing its oscillations due to the fall impact, preform resting within said groove, terminating passage from a substantially vertical position to a substantially horizontal position.

2. System according to claim 1, characterized in that said inspection system provides a supply system and a tunnel, along which preforms advance following a path in correspondence of which cameras for observing preforms are provided.

3. System according to claim 1, characterized in that transfer of preforms from inspection system to the weighting system is realized by a channel comprised of plastic material cannulae.

4. System according to claim 3, characterized in that said channel provides eight cannulae.

6. System according to claim 1, characterized in that said guide is comprised of crystalline polymeric material, preferably an acetalic resin, and particularly polyoxymethylene or POM-C, and it is coated with nitrilic rubber or anti-oil strips.

7. System according to one of the preceding claims claim 1, characterized in that, at the end of said guide, it is provided a stop system or blades, rotating according to the preform advancement direction within the weighting system, along a belt, to stop preform arriving from the guide and, after weighting, supplying it to the selection system.

8. System according to claim 1, characterized in that said weighting system provides a load cell on masse, particularly masse weighting 60 kg, resting on anti-vibration elements, so as to eliminate all low frequency vibrations.

9. System according to claim 1, characterized in that said preform selection system is of the pneumatic type.
