Defect Detect System For Glass Bottles

img

Puretronics is proud to present Bottle Inspection System in collaboration with QVision Italy. It is a modular vision system, which can be equipped with one or more standard inspection modules; each module is dedicated to specific controls, in order to detect the typical defects of this kind of production. Standard modules are available for the inspection of bottle and vials (with circular symmetry, uniform color, without printing or decorations). The system can be installed on existing production lines, if necessary technical requirements are fulfilled, or it is possible to offer «turnkey» solutions, supplying the vision system complete of a proper mechanical transportation unit.

This product line includes also a special system for the on-line inspection of bottles bundles, enclosed in heat-shrink film (“QVision-HeatShrink Bundles Control”). The inspection software is fully owned by QVision-Tech. It is therefore possible, on request, to provide customized versions, together with dedicated hardware configurations, to meet specific customer needs.

  • Features
  • QVISION-B-SIDE : For the inspection of the external side surface of the bottle. The acquisition unit uses four cameras, installed at 90° each other. The unit is installed on a conveyor belt, with bottles moving aligned and spaced. Typical defects that can be detected with this unit are: contaminations/dirty on the external side surface.
  • QVISION-B-TOP : For the inspection, with a top-view, of the opening of the bottle/vial. The optics and the lighting system used for this module, are designed to properly highlight the typical defects on the bottle opening (as missing material, deformation, contamination, ovality, flashes that occlude the opening). This module can be installed either on a conveyor belt or on a star-wheel.
  • QVISION-B-BOTTOM : For the inspection of the bottom surface of the bottle/vial. Usually this inspection is performed with a bottom view, while vials move supported by two side belts, in order to have the bottom surface free for observation. Typical defects that can be detected with this unit are: contaminations/dirty.
  • QVISION-B-HSB : Inspection of the proper packing of vials, arranged in multiple rows, wrapped in heatshrink transparent film. The inspection is usually performed while packs move on a roller conveyor, with a line-scan camera and a backlight system.
Defects :

The three modules “Side”, “Top” and “Bottom” are available also for the inspection of PET preforms. In this case a special handling system can be supplied, because of the particular geometry of the preforms.
