Loginspect: Empty bottle inspection

Logistics and Controls

Loginspect : Checking of quality, untactness and cleanliness of empty containers.


Linear empty bottle inspection system.
Modular inspection system, installed before the filler, to inspect the surfaces of empty bottles and jars made of either glass or PET. It checks that containers are in good condition and clean, free of foreign matter and liquid residues

The sidewalls are inspected to detect foreign matter, contaminants and breakage and to check the degree of scuffing. Two separate modules: the first one at the infeed also checks the profile of the bottle; the other one at the outfeed carries out a more complete check of the walls as the bottle is rotated inside the machine: the independent motorization of the belts allows the bottles to be rotated with a constant angle, irrespective of their diameter.

New multi-camera system: enables the walls to be inspected with unprecedented quality and resolution, without using mirror systems.

This identifies bottles with residues of water in the bottom, by means of a special high-frequency sensor. It is particularly sensitive to small traces of caustic soda. A special bottle guide enables the maximum sensitivity to be obtained even with diameter variations in the bottles.


The bottle finish is inspected
for breakage or scuffing on the sealing surface.
A particular angled light enables highlighting of the inner and outer edge of the bottle finish and also the tiniest breakages. 


The thread is inspected to identify breakages or scuffing, by means of a special optical unit that enables the entire length of the thread to be displayed as a pale spiral on a black background. The image is expanded and spread on a plane to check it effectively from the processing software. 


  • Stainless steel frame and panels. 
  • The main module moves the containers by gripping them at the side by means of 4 special belts with an elastic contact surface. The firm grip of these belts enables the bottom and the lip of the container to be inspected effectively. 
  • Machine base free of obstructions for easy and quick sanitation. 
  • All the lighting systems are with high efficiency pulsed LEDs, to guarantee maximum reliability, long life and image repeatability over time. 
  • High-end industrial PC with touchscreen monitor: no hard disk and no UPS needed. 
  • Motorized adjustment of the height of the cameras and the width of the belts, which are the only mechanical adjustments necessary for the expansions.
  • Size changeover: there is no need to replace mechanical parts.
