Solutions & Stories

Executive Summary

Client Profile: A large-scale pharmaceutical manufacturer with a diverse portfolio of solid dose products (SKUs).
Challenge: Independent operation of blister packaging and cartoning machines created speed mismatches, frequent stoppages for manual buffering, and reliance on error-prone manual feeding and verification, leading to compliance risks, low overall line efficiency, and broken data chains.
Our Solution: A fully synchronized "Blistering-Inspection-Intelligent Cartoning" integrated line featuring smart buffering, coordinated control, and 100% automated handling.
Key Impact: Achieved unmanned continuous production from blister to carton, increasing overall line efficiency by over 40%, eliminating quality risks from manual intervention, and establishing an end-to-end digital traceability chain.

The Core Pain Point: Disconnected Processes, Dual Loss of Efficiency & Quality

1. Efficiency Bottleneck: Speed mismatch between high-speed blister machine and cartoner required intermediate stacking or manual transfer, causing intermittent machine idling or waiting.

2. Quality & Compliance Risks:

   • Manual insertion of leaflets and cartons risked omissions or errors.

   • Matching different batch/lot blister cards to the correct cartons relied on visual checks, creating mix-up risks.

   • Defective blister cards (empty pockets, missing tablets) could flow downstream, causing packaging waste or customer complaints.

3. Data Silos: Separate data from blister and cartoning processes made it difficult to form complete packaging batch records and complicated audit trails.

4. High Space & Labor Footprint: Intermediate buffer areas and numerous operator stations occupied valuable cleanroom space and increased management costs.

Our Integrated Solution

We built a synchronized production cell centered on an Intelligent Central Dispatching System, safeguarded by High-Precision Vision Inspection, and connected via Flexible Robotics.

1. Intelligent Buffering & Coordinated Scheduling System

• Dynamic Buffer Tower/Matrix: Replaces traditional flat buffer zones with a vertical or matrix-style storage system. It receives blister cards from the blister machine and automatically feeds them to the cartoner on-demand following a FIFO principle, based on the cartoner's rhythm.

• Synchronization Control Engine: Continuously monitors the running status, speed, and fault signals of both the blister machine and cartoner. Automatically adjusts the speed or activates buffer mode for one side if the other stops (for changeover or fault), preventing jams or idle running.

• Smart Replenishment Alert: Automatically sends a replenishment request to the warehouse when carton or leaflet levels fall below the set threshold.

2. End-to-End Vision Inspection & Quality Gating

• In-line Blister Inspection Station: Before entering the buffer, a high-resolution camera performs 100% in-line inspection of each blister card. Checks include: Blister Integrity (ruptures, seals), Content Presence/Absence (missing or extra tablets), Cosmetic Defects, and critical Print Verification (product name, batch number, expiry date).

• Intelligent Rejection: Defective blister cards are automatically marked and rejected into a scrap bin. Qualified cards proceed orderly into the buffer system. Key quality data (defect type, count, location) is uploaded in real-time.

• Final Verification Station: At the carton entry point, a vision system performs a final match-check, ensuring the blister card information corresponds exactly with the carton and serialization code (if applicable) to prevent any batch mixing.

3. Robotic Flexible Cartoning Cell

• High-Speed Delta or Collaborative Robots: Precisely pick the specified number of blister cards (e.g., 1 or 3) from the buffer, simultaneously pick a folded leaflet, and gently place both into the pre-opened carton.

• Adaptive Gripping: Vision-guided systems assist robots in precise positioning, adapting to different blister card sizes and configurations.

• High Flexibility Design: Quick change-over of robot end-effectors and program calling allows easy adaptation to various product specifications with minimal changeover time.

4. Unified Central Control & Traceability Platform

• Single-Pane-of-Glass Monitoring: Real-time overview of the blister machine, inspection station, buffer system, robots, and cartoner—displaying status, efficiency, and alarms on one screen.

• Automatic Electronic Batch Record Linking: The system automatically links the blister card's batch number, production time, and inspection results with the final carton's case code and serialization data, generating a complete packaging batch record with one click.

• Performance & Waste Analytics: Accurately tracks output, yield, and downtime for each segment, identifying efficiency bottlenecks and primary causes of waste to support continuous improvement.

Key Features & Optional Extensions

• Modular Design: Clients can implement in phases based on their current setup (e.g., start with "Blister + Inspection," then integrate cartoning).

• Extendable to Case Packing & Palletizing: This integrated line can seamlessly connect to automated case packers and palletizing robots, forming a complete end-of-line packaging solution.

• Compliant with Global Regulations: System design adheres to GMP requirements, with data management meeting FDA 21 CFR Part 11 and EU GMP Annex 11.
