Say Goodbye to Material Breakage and Counting Errors: Experience High-Efficiency Special Vertical Packaging

The Automatic Special Vertical Packaging Machine (Bucket Chain & Counting Series for Fragile Materials) is an industrial-grade, high-efficiency automation assistant designed to solve special packaging pain points such as fragile material breakage, difficulty in automatically dosing irregular parts, inaccurate piece counting for precision items, and severe impact in traditional drop chutes.

LANTU Machinery introduces core models including Bucket Chain Manual/Semi-Automatic Conveyor Vertical Packaging Machines and High-Precision Photoelectric/Vision Counting Vertical Packaging Units. Featuring low-drop flexible inclined feeding chutes, manual/automatic bucket chain dumping mechanisms, and highly sensitive multi-channel photoelectric counting units, paired with high-precision servo film pulling and pneumatic/servo horizontal sealing systems, the equipment acts like a precise and gentle material packaging expert. Whether handling extremely fragile snacks like egg rolls, biscuits, rice cakes, freeze-dried foods, and potato chips (e.g., 10g–500g pillow bags/gusseted bags) or industrial and pharmaceutical products requiring strict piece/unit counting like capsules, pills, fasteners, small screws, plastic clips, and electronic components, it achieves flexible conveying, precise counting/manual feeding, automated bag forming, and flat sealing in one seamless operation—ensuring zero breakage, accurate counting, and tight sealing.

As an original manufacturer of packaging machinery, LANTU Machinery has simplified the complex fully automatic vertical process—bucket chain synchronized dumping/photoelectric counting, flexible chute buffering, film pulling & forming, horizontal/vertical sealing, and coding—into an operation as simple as using a smartphone. Operators simply set the target count/bag length on the PLC touchscreen, place materials into the bucket chain or pour them into the counting disk, and the machine automatically performs photoelectric counting/synchronized dumping, film pulling, bag forming, and sealing before smoothly outputting finished bags. With bag widths ranging from 50mm to 250mm, this series significantly shortens packaging workflows while saving labor, time, and costs.

Choosing a reputable source manufacturer is crucial for your return on investment. LANTU Machinery’s proven flexible inclined feeding and multi-channel photoelectric counting technologies, combined with robust reliability and industry-leading film utilization, ensure smooth, zero-breakdown operation on your special vertical packaging lines.

Pneumatic Anti-Clamping Buffer Doors: Equipped with pneumatic buffer doors at the bucket dumping and counting discharge ports to ensure smooth material entry without compromising seal areas.

2. Bag Forming and Sealing-Cutting System

Precision One-Piece Bag Former: Crafted from 304 stainless steel with mirror polishing, ensuring smooth film passage without scratching and crisp bag shaping.

Dual/Single Servo Drive Control: Utilizes servo motors to control film pulling and sealing actions with rapid response, guaranteeing smooth film transport without tracking offset over millions of cycles.

PID Smart Temperature Control & Anti-Clamping Sensors: Vertical and horizontal sealing jaws feature independent PID smart temperature modules paired with rebound sensors to completely eliminate seal leaks and cutting damage.

Multi-Functional Auxiliary Bag Units: Standardized with gusseting devices, hole punchers (round/Euro hole), chain bag cutters, and gas-flushing/exhaust ports to accommodate diverse packaging needs.

3. Intelligent Control and Safety Protection System

Siemens / Mitsubishi PLC Central Control: Industrial-grade multi-core CPU control providing stable operation, strong anti-interference capabilities, and support for 10 languages.

Photoelectric & Signal Interlock Control: Millisecond-level seamless interlock between bucket chain dumping or counting signals and film pulling/sealing; no film pulling without material, auto-pause on empty bags.

Fully Enclosed Safety Guard Doors: Heavy-duty 304 stainless steel frame equipped with transparent safety doors that automatically pause operation when opened, complying with GMP and food/pharma hygiene standards while ensuring operator safety.

Key Factors to Consider When Purchasing a Special Vertical Packaging Machine

To help you choose the best machine for your production line, consider the following key selection criteria:

Material Physical Properties (Bucket Chain vs. Counting Type):

Extremely fragile, irregular shapes, or requiring manual multi-item combination placement: Select Bucket Chain Vertical Packaging Machine;

Uniform shapes, free-flowing, requiring exact piece counts (e.g., 10 pcs/bag, 50 pcs/bag): Select Photoelectric/Vision Counting Vertical Packaging Machine.

Target Bag Dimensions and Maximum Film Width:

Bag Width 50mm–150mm: Select Small Special Model;

Bag Width 100mm–250mm: Select Medium Special Model.

Film Material & Thickness: Composite films (OPP/CPP, PET/PE) use standard heated sealing jaws; single-layer PE film requires a dedicated PE film impulse sealing system.

Target Capacity (BPM): Choose bucket stations or multi-channel counting disks based on speed requirements (e.g., 20–60 bags/min).

Special Functional Modules: Nitrogen gas flushing, date coding (ribbon/laser), gusset forming, or Euro hole punching.

Frequently Asked Questions (FAQ)

Q1: What manual operation scenarios are suitable for bucket chain vertical packaging machines?

A: Ideal for irregular items that cannot be fed automatically via vibratory bowls, long fragile snacks (like egg rolls), or mixed packaging scenarios requiring workers to manually place 2–3 different parts (e.g., screw + nut + washer) into a single bucket.

Q2: How is counting accuracy guaranteed on counting packaging machines?

A: We utilize multi-channel high-sensitivity photoelectric sensors and beam-overlap algorithms to distinguish closely spaced or fast-falling items; paired with over-feed alerts and under-count rejection interfaces, ensuring 99.9% counting accuracy.

Q3: How difficult is adjustment when changing bag sizes or materials?

A: Extremely simple. Buckets and bag formers feature quick-release structures. Simply adjust bag length and counting parameters on the PLC touchscreen, with full specification changes taking under 10 minutes.
