ブリスター包装機用フィーダーの選び方? 6 医薬品包装ソリューション用フィーダー

導入: In the blister pack packaging process, the feeding system determines the overall efficiency of your line. Forming and sealing stations often get the most attention, but the feeder is the real bottleneck that controls production output.

Pharmaceutical cGMP manufacturing faces common pain points: high empty cavity rates at high speeds, tablet breakage, dust buildup, and long changeover times that cut into effective production hours. Choosing the wrong blister machine feeding system not only increases material waste and inspection rework rates, but also creates a capacity bottleneck for your entire production line.

1. Brush Feeder

仕組み: As the standard configuration on most general-purpose blister packing machine models, the brush feeder uses rotating soft brushes to sweep material at a steady pace. Material falls into blister holes by gravity, and excess material automatically recirculates back into the system. No custom molds are required, making it highly versatile. A three-stage dust and static elimination system is available as an optional upgrade for uncoated plain tablets that generate heavy dust.

長所:

• Suitable for multi-product flexible production, no frequent part changes needed
• シンプルな構造, 低い故障率, easy disassembly and cleaning, meeting cGMP manufacturing cleaning standards
• Low buying and maintenance cost, fits multi-spec small and medium batch production.
• Gentle feeding action, less likely to crush regular tablets or standard hard capsules

短所:

• Brushes are wear parts; long-term use causes bristle loss, requiring regular replacement
• High-speed operation can scratch coated tablets or damage aluminum foil
• Stability drops during high-volume mass production, increasing the chance of empty cavities and missing material

に適しています: Round tablets, oval coated tablets, 噛むことができるタブレット, standard hard capsules.

Not suitable for: Fragile tablets, ソフトカプセル, or hard capsules requiring oriented arrangement.

2. Waterfall Guide Rail Feeder

Jinlu Packing’s Waterfall Guide Rail Feeder holds national patents. Its multi-layer waterfall layout delivers fast feeding speed, with built-in vibration and dust removal functions. The feeder’s height can be adjusted front and back, and mold replacement is done simply via handwheels. This feeder boasts wide versatility. It works well for standard round tablets and capsules, and is also compatible with square tablets and other special-shaped tablets.

仕組み: Uses fixed parallel guide rails. Material slides smoothly down by gravity, automatically arranging into a single column and dropping precisely into blister cavities.

• Extremely high feeding accuracy, reaching 99.97%
• No squeezing or friction throughout the process, effectively preventing capsule or tablet breakage and powder loss, with high yield rates
• Stable operation with low dust generation, suitable for clean rooms
• Clear material path, easy for routine inspection
• No complex transmission parts, easy to maintain and clean

短所:

• Customized rails required for each product specification, higher cost
• Sticky coatings can build up and cause bridging jams

に適しています: ハードカプセル, 楕円形の錠剤, もっと. Can be configured on both flat-plate like DPP 270 マックス, DPP 370 Ultra, and roller-plate like DPH 190 Pro, DPH 270 Max machines. It is the preferred choice for mature fully automatic blister packaging machine production lines and meets cGMP manufacturing requirements.

3. Vibratory Track Feeder

仕組み: Uses electromagnetic vibration to drive the track and feed material at a steady pace. Vibration frequency and amplitude are adjustable, achieving orderly single-column material delivery. It eliminates stacking jams and delivers precise feeding matched to the machine’s traction rhythm.

長所:

• Adjustable parameters, adaptable to pharmaceuticals of different weights and friction levels
• Continuous and stable feeding, solves bridging and jamming issues
• Gentle feeding without hard squeezing, suitable for fragile coated tablets and soft capsules, with high yield rates

短所:

• Slight noise during long-term operation; high-frequency vibration mildly affects equipment stability
• Ultra-lightweight or highly sticky materials may feed unevenly
• Parameter re-adjustment required after product changeover, requiring some operator skill

に適しています: Various tablets, コーティング錠, ソフトカプセル, and vegetarian hollow capsules.

4. Rotary Drum Feeder with Guide Rails

仕組み: Uses a custom rotating drum with precision-machined grooves. It picks up a single pharmaceutical dose per groove, synchronized with the blister film traction rhythm, delivering material at fixed points and times for high-precision quantitative filling.

長所:

• Strong feeding synchronization and precise positioning, extremely low empty cavity and missing material rate
• Good stability and strong anti-interference during continuous mass production
• Compact structure saves space, suitable for integrated automated packaging solutions, with high packaging consistency

短所:

• Custom-machined exclusive mold, single-specification for single product; multi-product changeover is costly
• Pharmaceutical residue can clog and cause malfunctions
• Irregular, oversized, or undersized materials are prone to crushing damage
• Feeding rhythm is relatively slow

に適しています: Standard round tablets with uniform dimensions, regular tablets.

Not suitable for: ソフトカプセル, 不規則な錠剤, or fragile pharmaceuticals.

5. Spring Feeder

仕組み: Uses a rotating helical spring with fixed pitch spacing to separate individual doses. It continuously pushes material to the feeding station. Simple structure with stable transmission, suitable for continuous feeding of small granular pharmaceuticals.

長所:

• Strong conveying capacity, suitable for small tablets, blister packs for pills, and spherical granules
• ドライ, non-sticky materials are less likely to jam or clog
• Speed syncs with main machine for simple control

短所:

• Spiral pushing can wear tablet coatings and damage appearance
• Cannot adapt to soft, easily deformable soft capsules, which are prone to crushing damage
• Feeding rhythm is relatively slow

に適しています: Round tablets, square tablets, 等. Mostly used on low-to-medium speed small and medium-sized blister pack machine equipment.

6. Capsule Orientation Feeder

仕組み: A dedicated feeding structure for hard capsules. Through orientation channels and an automatic flipping and sorting mechanism, it corrects capsule posture and unifies orientation. Inverted or misaligned capsules automatically recirculate for re-sorting, completely solving the capsule inversion problem.

長所:

• Achieves oriented arrangement of hard capsules, meeting visual inspection and precision packaging requirements
• Eliminates inverted defective products and rework
• No hard squeezing, capsule shells are less likely to crack or break, suitable for high-end cGMP standard production lines

短所:

• Highly specialized, only suitable for hard capsules
• Parts must be changed for different capsule specifications
• Larger equipment footprint, higher purchase and commissioning costs

に適しています: Gelatin hard capsules and vegetarian hollow hard capsules. It is the configuration for high-end capsule-specific blister packaging pharmacy production lines.

結論

The six types of blister machine feeding system each have their own suitable applications – there is no universal one-size-fits-all model.

• Brush feeders offer high cost-effectiveness and suit multi-product flexible production.
• Waterfall guide rail feeders balance high speed, 安定性, and aluminum foil protection, making them the mainstream mass production choice.
• Rotary drum feeders suit single-product high-precision production.
