Ampoule Visual Inspection Machine

The Ampoule Visual Inspection Machine manufactured by Technogen Enterprise is a semi-automatic pharmaceutical inspection system designed to assist trained operators in visually examining sealed liquid-filled ampoules. The equipment supports inspection for visible foreign particles and apparent glass-container defects by combining high-speed ampoule spinning, controlled illumination and magnification.

The machine is intended for the inspection of compatible glass ampoules containing pharmaceutical or injectable formulations. The described inspection targets include glass fragments, dirt particles, black particles, filter-medium residues and visible cracks. As the system uses human visual assessment, detection performance depends on the inspector, viewing conditions, product characteristics and the inspection method.

The equipment incorporates six ampoule spinning assemblies. During inspection, rotation produces motion within the liquid, helping suspend or move visible particles so the operator can distinguish them against the inspection background. The spinning speed is adjustable according to the container and liquid properties.

A magnification arrangement provides an overall viewing magnification of approximately 1.75×, with localized magnification up to 3×. Two 18 W magnifying lamps, each described as providing approximately 1800 lumens, illuminate the inspection area and support simultaneous viewing of six ampoules.

The machine uses tray-based ampoule loading and a synchronized transport arrangement. A reflex photoelectric sensor mounted at an aluminium starwheel supports container separation and positioning. Separate variable frequency drives are specified for the main machine and ampoule spinning mechanism.

The stated inspection capacity is 50–60 ampoules per minute, corresponding to approximately 3000–3600 ampoules per hour under suitable conditions. Actual output depends on inspection duration, product quality, operator judgment and the frequency of repeat inspection.

An operator-actuated ejection switch supports rejection handling. The machine is equipped with two counters, one monitoring total production and the other recording rejected ampoules. A repeat-cycle arrangement allows containers to undergo additional inspection when required.

The machine has a premium stainless steel matt-finished body and uses AISI 304 stainless steel in the specified construction. It accommodates stated ampoule diameters of 10–15 mm and heights of 55–125 mm, with suitable change parts required for different container configurations.

Technogen Enterprise manufactures, supplies and exports pharmaceutical inspection equipment from Ahmedabad, Gujarat, India, providing operator-assisted visual inspection solutions for manufacturers requiring controlled ampoule presentation, lighting and counting functions.
