ROVI Getaktetes Prüf- und Sortiersystem für Serienteile
Indexing system, handling systems & robots

ROVI is an inspection system with a rotary indexing table, which positions each individual part in front of one or several sensor units. The system has been designed for parts with complex geometries or very high inspection requirements. In addition to surface and geometrical defects, the system can also detect defects on threads.

Typical inspection tasks for a ROVI system are, for example, seals which have to be stretched or squeezed in order to find hidden fissures, or parts with specific threads, sealing areas, tooth flanks or undercuts that have to be inspected with a very high resolution or even line by line.


Suited for parts made of different materials such as metal, plastics, rubber & other elastomeric compounds, silicone, sintered metal.

Indexing table

Rotary or linear system that individually positions each part in front of or underneath the sensors.

Optical inspection

High-resolution image capture for a reliable inspection of surfaces and geometric elements, as well as threads.


Fully automated feeding and separation of parts, for example with ascending conveyors or bowl feeders.


Bunkers with different capacities are available for improved autonomous times.

Customized solutions

Pick and place units and handling robots are available for special inspection tasks that cannot be handled by a standard system.


Parts are classified and sorted as OK or NOK parts. Statistics include data for the entire system, as well as for individual sensors.


OK parts can be diverted automatically to a box changer or packaging system.


Technical information at a glance:

  • Dimensional check and defect inspection on all surfaces (top, bottom, lateral)
  • Throughput up to 1.800 parts per hour
  • Optimized for part sizes from OD 15mm - 100mm
  • Measuring accuracy from ± 1μm 
  • Sorting of inspected parts into up to 8 sorting channels
  • Robust machine design and use of high-quality technical components
  • Powerful multi-core processors for very high inspection speeds 
  • Closed design for maximum cleanliness inside the inspection system; this is a requirement for many applications in the medical packaging industry

Your advantages in daily production:

  • Continuous and reliable optical inspection and sorting showing no signs of fatigue
  • Documented quality including generation of the relevant process data, e.g. statistics for the entire system or individual sensor units, process data acquisition, or status exchange via OPC-UA.
  • Modular system suited for a large variety of parts with different sizes, shapes, and material characteristics.
  • 100% Inspection
  • Highly precise measurement and surface quality check in one system, stretching and squeezing of elastic parts is possible

Glass table inspection systems from NELA are available in several – customized – versions:

Depending on the characteristics of your parts and on the inspection requirements, the ROVI system may be designed as a rotary or a linear transfer system. If needed, handling systems or robots can be added. Each part is picked up individually and is transported along or underneath the inspection sensors. In the pick-up units, the part can be rotated in all directions for a highly precise inspection from all sides. Elastic parts can be squeezed or stretched to detect hidden defects such as cracks or fissures. Sorting can be realized with paddles or air nozzles; an integration with other production equipment or packaging stations is possible upon request.

Careful handling along the entire inspection and sorting process guarantees that parts are not damaged.

Our sales team is happy to receive your enquiry or call and will recommend the appropriate system for your application, depending on geometry, size, material, and inspection requirements.
