Automatic Rotary Ampoule Sticker Labeling Machine
High-Precision Labeling for Sterile Lines
The Harsiddh Automatic Rotary Ampoule Sticker Labeling Machine (HASL-300R) is the premier solution for high-speed pharmaceutical packaging. By utilizing a rotary star-wheel indexing system, the machine ensures that fragile ampoules are gripped at three points during labeling for maximum stability. This system is designed for “tray-to-tray” operation, allowing for vertical loading and collection, which significantly reduces the risk of glass breakage compared to traditional slant-hopper systems.
Reliable Operational Workflow
The machine provides a continuous, high-efficiency labeling cycle:
- Vertical Loading: Ampoules are fed into the in-feed hopper or directly from trays into the conveyor in a vertical position.
- Star-Wheel Indexing: A feed worm transfers the ampoules to the rotary star-wheel, which carries them securely through the labeling zone.
- Label Application: As the sensor detects an ampoule, the servo-controlled applicator releases the label precisely onto the rotating container.
- Secondary Pressing: A synchronized pressing unit ensures the label is firmly adhered and perfectly aligned around the circumference.
- Discharge & Collection: Labeled ampoules are automatically collected in the out-feed tray in a vertical position, ready for final inspection or secondary packaging.

Frequently Asked Questions
How does the machine ensure the label is applied perfectly straight on the ampoule?
Precision is maintained through a synchronized Wrap-Around station. As the ampoule rotates within the star-wheel, it comes into contact with a motorized foam-lined "pressing belt." This belt spins the ampoule on its own axis while the label is dispensed, ensuring the sticker wraps smoothly without wrinkles, bubbles, or "spiraling" (skewed alignment). The machine achieves a placement accuracy of ±0.5mm.
Can the machine handle different ampoule sizes (e.g., 1ml vs. 10ml)?
Yes. The machine is highly versatile and can accommodate standard glass ampoules from 1ml to 25ml. To switch between sizes, the operator simply changes the Star-Wheel and adjusts the height of the labeling head. The PLC-based Touchscreen HMI allows you to save specific speed and timing "recipes" for each ampoule size, making batch changeovers fast and repeatable.
What quality control features are integrated into the Rotary Labeler?
To comply with stringent pharmaceutical "Track and Trace" regulations, the Harsiddh Rotary Labeler includes:
"No Ampoule – No Label" System: Electronic sensors prevent label wastage if a pocket in the star-wheel is empty.
Integrated Coding: Compatibility with Thermal Inkjet (TIJ) or Laser coders to print Batch Nos. and Expiry Dates.
Vision Inspection & Rejection: An optional high-speed camera can verify label presence and code legibility. Any defective ampoule is automatically diverted into a "Reject" bin via a pneumatic pusher without stopping the machine.
What are the key cGMP and safety features of this model?
As a cGMP-compliant unit built for sterile environments:
Material Integrity: All contact parts are made of SS 316L, and the main frame is SS 304 with a high-polish finish for easy sanitization.
Safety Enclosure: The moving rotary parts are protected by a toughened glass cabinet with safety interlocks.
Automatic Synchronization: The speed of the in-feed, star-wheel, and labeling head are all digitally synchronized via a centralized PLC to prevent glass breakage or jamming.
