Auxiliary equipment for blister packaging machines are crucial components in building efficient, stable, and automated production lines. They surround the core machine, handling pre-processing, post-processing, quality control, and production support, collectively improving overall production efficiency, product quality, and automation levels. The following are the main categories of auxiliary equipment and their detailed descriptions:
I. Pre-processing and Feeding Auxiliary Equipment
These devices are responsible for accurately and precisely delivering the products to be packaged to the blister machine's filling station in optimal condition.
1. Lifting Feeder/Vacuum Feeder:
- Function: Lifts and transports products (such as tablets and capsules) from drums or bags to the main machine's hopper using vacuum or mechanical means, reducing manual handling and dust exposure, especially suitable for large-volume production.
2. Dust Removal and Screening Machine (Granulator):
- Function: Removes fine powder, fragments, and dust from the product using a vibrating screen and aligns the products (such as capsules). The core function is to improve filling accuracy, reduce false positives in inspection, and keep the molds and sealing areas clean, which is crucial for products that easily generate dust.
3. Precision Counting Feeding System:
- Function: Replaces simple vibrating hoppers, using multi-stage vibrating plates, counting screws, or servo-driven precision guides to achieve high-precision, low-wear, directional, and orderly arrangement and supply of products. This is especially necessary for fragile or easily sticky products such as irregularly shaped tablets and soft capsules.
II. Online Quality Inspection and Control Equipment
These are the "eyes" and "brains" for achieving high-quality automated production, directly integrated into the production line.
1. Blister Online Leak Detection Machine (Vacuum Decay Method or High-Voltage Discharge Method):
- Function: 100% online detection of the sealing integrity of each blister pack, identifying leaks such as micro-holes and cracks. This is a key quality control device for sterile or high-barrier products (such as aluminum-plastic-aluminum blister packs) in the pharmaceutical industry, far exceeding the reliability of manual sampling.
2. Online Weighing and Rejection Machine (Checkweigher):
- Function: After cutting, it performs high-speed dynamic weighing of each blister pack to accurately determine whether there are missing, extra, or fragmented products, and automatically rejects unqualified products. It is a powerful tool for weight difference control. Metal Detector/Foreign
3. Object Detector:
- Function: Detects and removes metal impurities or other foreign objects (such as glass, minerals, etc.) that may be mixed into the product. This is an essential step for food and drug safety.
4. Vision Inspection System (AI Vision):
- Function: High-resolution cameras combined with AI algorithms can perform complex inspections: appearance defects of pharmaceuticals (damage, cracks, chipped edges), printing quality (batch number, expiration date clarity, position), blister pack forming defects, foreign objects in the sealing area, etc.
III. Post-Processing and Packaging Equipment
Completes the subsequent processing and packaging of blister packs.
1. Cartoning Machine:
- Function: Automatically folds and inserts blister packs, instruction manuals (and sometimes medicine bottles, etc.) into cardboard boxes. This is a core piece of equipment connecting inner and outer packaging. It can achieve high-speed, unmanned operation.
2. Pillow Packaging Machine/Three-Dimensional Transparent Film Packaging Machine:
- Function: Secondary packaging of single or multiple blister packs using composite film or shrink film to form retail units. It features moisture resistance, good display characteristics, and low cost.
3. Automatic Case Packing and Palletizing System:
- Function: Includes case erector, case packer, case sealer, strapping machine, and robotic palletizer, achieving fully automated downstream logistics from finished boxes to shipping cases and then to pallets.
IV. Production Support and Auxiliary Systems
Ensures stable operation of core equipment and production compliance.
1. Cooling Water Circulation System (Chiller):
- Function: Provides stable, controllable temperature circulating cooling water for the forming molds and cooling rollers of the blister machine. This is crucial for ensuring blister pack forming quality and increasing production speed.
2. Compressed Air System:
- Function: Provides stable, dry, and clean compressed air for pneumatic components (cylinders, vacuum generators, etc.) and cleaning and purging of equipment. Requires an air storage tank, dryer, and precision filter.
3. Waste Material Rewinder or Shredder:
- Function: Automatically rewinds or shreds the edge waste (plastic film and aluminum foil) after die-cutting, facilitating centralized processing and maintaining a clean work environment.
4. Central Monitoring and Data Acquisition System (SCADA/MES):
- Functions: Connects all equipment on the production line, monitors operating status in real time (speed, temperature, faults), collects production data (output, yield rate, downtime), and generates electronic batch records to meet GMP data integrity and production traceability requirements.
Summary:
Modern blister packaging production lines have evolved from standalone machines into highly integrated systems. When selecting auxiliary equipment, comprehensive planning should be based on product characteristics, capacity targets, regulatory requirements (such as GMP, FDA), and return on investment (ROI). A well-designed "main machine + auxiliary equipment" system can maximize the achievement of intelligent manufacturing goals such as "reducing manpower, improving quality, increasing efficiency, and ensuring traceability." When planning a new line, it is recommended to communicate in depth with the main machine manufacturer or system integrator for overall solution design.
