Semi-Automatic Metal Bucket and Tin Can Packaging Line 65-290mm Dia 60-420mm H 20-50 cans/min

This semi-automatic metal bucket and tin can packaging line handles cans and buckets with diameters from 65 to 290 mm and heights from 60 to 420 mm, at a production speed of 20–50 cans per minute depending on model and product dimensions. The line combines forming, seaming, filling-ready positioning, labeling, and stacking subsystems into a compact layout for medium-volume production. Key benefits include flexible size adjustment, durable stainless-steel construction, user-friendly controls, and easy maintenance. Typical applications include paint, chemical, lubricant, food, and industrial packaging. Optional modules and after-sales support make the system adaptable to specific product and regulatory requirements.

Product Details

Product Overview

The Semi-Automatic Metal Bucket and Tin Can Packaging Line is designed for medium-volume manufacturers who require reliable production of metal containers with diameters between 65 mm and 290 mm and heights between 60 mm and 420 mm.
Throughput: 20–50 cans/min (actual speed varies with can size, seam type, filling method, and operator skill).
Typical industries: paints and coatings, lubricants, adhesives, chemicals, food oils, and aerosol-free metal packaging.

Key Features

Size Flexibility: Fast-change tooling and adjustable guides accommodate a wide diameter and height range without major modifications.
Modular Design: Core modules can be reconfigured or expanded—seamer, top cap feeder, positioning table, labeling station, and stacker.
Robust Construction: Food-grade or industrial stainless steel contact parts; corrosion-resistant finishes for harsh environments.
User Interface: PLC control with touchscreen HMI for recipe storage (settings per can size) and simple troubleshooting prompts.
Safety & Compliance: Emergency stops, safety guards, and interlocks. Designed to meet CE and relevant regional safety standards upon request.
Low Maintenance: Easy-access bearings, quick-change sealing elements, and diagnostic indicators reduce downtime.

Standard Components and Functions

Feeding & Positioning Table

Manual or semi-automatic can loading, servo or motor-driven indexing table.
Adjustable clamps and centering devices to handle various diameters.

Seaming/Top/Bottom Processing Unit

Precision seaming head for reliable double-seam integrity on tinplate or lacquered substrates.
Adjustable seaming parameters to match material thickness and seam profile.

Filling Preparation & Transfer

Infeed conveyor and transfer arms stage cans for filling or lid application (line can be integrated with a separate filling machine).
Optional magnetic or vacuum hold-down to stabilize lightweight or empty cans.

Labeling Station (Optional)

Wrap-around or front/rear labeling modules compatible with pressure-sensitive or shrink labels.
Encoder synchronization for accurate placement at high speeds.

Stacking and Packing

Mechanical or pneumatic stacking into pallets, trays, or conveyors for secondary packing.
Accumulation buffer to decouple upstream and downstream operations.

Electrical & Control System

PLC-based control with touchscreen HMI, recipe management, and fault logging.
Standard industrial sensors, photoeyes, and safety circuits.

Technical Specifications (Representative)

Diameter range: 65–290 mm
Height range: 60–420 mm
Speed: 20–50 cans/min (dependent on format and configuration)
Power supply: 380V/50Hz (customizable)
Air consumption: specified based on optional pneumatic modules
Materials: SUS304/SUS316 stainless steel contact surfaces, carbon steel frame with powder coating
Machine footprint: depends on module set; typical semi-automatic line requires 6–15 m2

Installation and Site Requirements

Foundation: level concrete floor with anti-vibration pads recommended.
Space: allow clearance for operator access, maintenance, and infeed/outfeed conveyors.
Utilities: electrical supply, compressed air (dry, oil-free), and optional vacuum or inert gas lines depending on product.
Environmental: indoor environment free of extreme dust and corrosive fumes; ventilation recommended for solvent-based products.

Operation Workflow

Configure machine recipe on HMI for selected can size and seam parameters.
Load tooling and adjust guide rails and clamps for diameter and height.
Feed empty cans to the positioning table manually or with a hopper.
Transfer cans to seaming station; perform seaming and any required lid application or crimping.
Move cans to labeling and stacking stations; collect finished units for packaging.
Monitor sensors and HMI for alarms; stop line for jams or defective cans.

Maintenance and Spare Parts

Daily: clean contact surfaces, check alignment, and inspect seals and o-rings.
Weekly: lubricate bearings, check conveyor belts and chains, verify sensor alignment.
Monthly: inspect seaming rollers, fasteners, and motor coupling; tighten and replace wear parts as needed.
Recommended spare parts: seaming rollers, gaskets, bearings, belts, photoeyes, and PLC fuses.

Safety Guidelines

Train operators on emergency stop procedures and lockout/tagout before maintenance.
Ensure all guards and interlocks are engaged during operation.
For hazardous products, provide appropriate ventilation and PPE for operators.
Follow local electrical and safety codes for machine installation.

Optional Upgrades and Accessories

Automatic can unloader and palletizer
Integrated filling machine (piston, pump, or gravity fillers) for liquid products
In-line inspection systems (leak test, seam inspection, label inspection)
Inkjet or laser coder for date/lot coding
Explosion-proof electrical components for solvent-based product lines
Remote monitoring and IoT connectivity for production metrics

Packaging and Delivery

Machines are typically disassembled for shipping and packed with protective covers and corrosion inhibitors.
Installation and commissioning can be provided by factory-trained technicians.
Lead time varies with customization level; standard module delivery often within 6–10 weeks, customized lines quoted separately.

After-Sales Support

Training for operators and maintenance staff during commissioning.
Technical documentation including operation manual, spare parts list, electrical schematics, and maintenance schedule.
Warranty terms and optional extended maintenance contracts available.
Remote technical support and on-site service options.

Ordering Information

Provide required can dimensions (diameter, height, material), target speed, product type (viscosity, solvent), and desired modules (labeler, filler, coder).
Request a line layout and quotation including installation, commissioning, and training services.

This semi-automatic packaging line delivers a balance of flexibility, reliability, and cost-efficiency for manufacturers transitioning from manual methods to higher throughput while retaining ease of operation and maintenance.
