De-nest, handle and present filled glass vials/prefilled syringes for inspection

In Takeda's sterile fill-finish lines, filled primary containers (thin-walled glass vials, ampoules, and prefilled glass syringes) must be removed from their nests/trays and presented individually for visual inspection (particulates, cracks, fill level, cosmetic defects), then re-nested. The objects are fragile, slippery when wet/siliconized, and held to sub-millimeter pocket tolerances in nests. The task sits between filling/stoppering upstream and packaging/AVI downstream, and is high-volume parenteral output. It is hard for a robot because each pick must avoid glass-to-glass and glass-to-tool contact that chips or micro-cracks the container, while reliably seating the unit back into a tight nest pocket; vision alone cannot confirm a safe, non-damaging grasp. Industry inspection systems explicitly engineer their de-nest/inspect/re-nest handling to prevent glass-to-glass contact, underscoring the difficulty. We identified this through our own research; we have not confirmed the specifics with the customer directly. This page is our researched read — a starting point for that conversation.
