Professional Solution for Automatic Valve Bag Sleeving Machine (Dry-Mix Mortar)

I. Core Requirements Analysis

• Bag Type Compatibility: Valve bags (square/round bottom), standard 20-50kg sizes (e.g., 500×350×100mm).

• Material Characteristics: Dry-mix mortar with high dust emission, poor flowability, requiring moisture-proof sealing.

• Automation Target: Full automated process (bag picking → opening → sleeving → positioning → sealing) at ≥600 bags/hour.

II. Key Equipment Components

1. Bag Storage System:

• 3D bag rack (1000+ bag capacity) with servo-driven robotic arm/vacuum suction cup dispenser.

• Photoelectric sensor ensures single-bag separation to prevent doubling.

2. Bag Opening Mechanism:

• High-pressure air nozzle + mechanical fingers combo, opens valve mouth in 0.5s.

• High-sensitivity pressure sensor verifies opening success.

3. Sleeving & Positioning Module:

• 6-axis robot (≥10kg payload) with vision system (CCD camera + AI algorithm), ±0.5mm accuracy.

• Adaptive gripper for multi-bag types (PE-coated/paper-plastic composite).

4. Sealing Unit:

• Heat-sealing/ultrasonic sealing (200-400℃ adjustable) with leak detection (vacuum test).

5. Dust Control:

• Localized negative-pressure hood + pulse-jet dust collector, ≤5mg/m³ dust concentration (OSHA compliant).

III. Technical Innovations

• Adaptive Sleeving: Force-feedback robot adjusts gripping force (5-20N adjustable) to prevent tearing.

• Self-Diagnostics: PLC-based HMI displays real-time error codes (e.g., low stock, sealing temp anomaly) with remote O&M support.

• Quick-Change Design: Modular grippers + parameter memory, bag-type changeover <5 mins (pre-loaded parameters required).

IV. Performance Specifications

V. Industry Applications

• Building Materials Group: Replaced manual sleeving, achieved <0.5% failure rate + 70% labor cost reduction.

• Specialty Mortar Project: ATEX-certified explosion-proof model for epoxy mortar packaging.

VI. Selection Guide

• Cost-Effective Option: Chinese OEM (e.g., Dongguan brands) ~¥250-400k, 400 bags/hour.

• Premium Option: European imports (e.g., Haver & Boecker) ~¥800k-1.2M, 1000 bags/hour with 3D vision alignment.
