Product Introduction‌

The ‌Automatic Stacking High Level for Bag Hot selling Rotot Palletizer Stacking‌ is an advanced industrial automation solution designed for efficient and precise palletizing of bagged products across various industries.This high-level palletizer is engineered to transport bags to a specified height, where they are systematically arranged, grouped, and stacked onto pallets according to pre-programmed PLC sequences. The machine is particularly suited for handling large bags of materials such as fertilizer, flour, cement, rice, chemical raw materials, and feed stuffs, with a capacity ranging from 20–50kg per bag.

Key competitive advantages include:

• High Efficiency‌: Capable of processing 40–230 bags per minute, depending on bag dimensions and stacking patterns.

• Adaptability‌: Compatible with various bag sizes (65–280mm length × 30–160mm width) and materials, including woven polypropylene and paper bags.

• Smart Integration‌: Features a touch-screen interface for easy operation and real-time monitoring, with PLC-controlled synchronization for seamless stacking.

• Cost-Effectiveness‌: Priced competitively at 11,000–50,000 per unit, offering rapid ROI through reduced labor costs and energy-efficient operation.

The machine’s modular design, constructed from durable SUS304 stainless steel, ensures compliance with ISO 9001 and CE standards, making it suitable for hygienic environments in food and pharmaceutical applications.

Operating Instructions‌

Pre-Production Setup‌

1. Bag Feeding Configuration‌

   Align the conveyor system to feed bags into the palletizer.Adjust photoelectric sensors to detect bag positioning accurately.

2. PLC Programming‌

   Input stacking parameters (e.g., layer count, pattern) via the touch-screen HMI.Test with 10–20 empty bags to verify alignment.

3. Pallet Loading‌

   Place empty pallets on the outfeed conveyor, ensuring they are centered and level.

Production Workflow‌

1. Bag Transport‌

   Bags are conveyed to the lifting mechanism, which elevates them to the stacking height.

2. Pattern Formation‌

   The rotary arm arranges bags into predefined patterns (e.g., 5 bags per layer, 6 layers per pallet).

3. Pallet Discharge‌

   Completed pallets are conveyed out for wrapping or storage, while empty pallets are automatically fed in.

Maintenance Protocols‌

Daily‌: Clean residual dust from sensors and conveyors;inspect sealing jaws for wear.

Weekly‌: Lubricate chain drives with food-grade grease;calibrate load cells.

Monthly‌: Replace worn belts;inspect electrical connections and pneumatic lines.

Troubleshooting & FAQs‌

Common Operational Issues‌

1. Misaligned Bags‌

   Cause: Incorrect sensor calibration or conveyor speed mismatch.

   Solution: Recalibrate photoelectric sensors and adjust conveyor speed synchronization.

2. Inconsistent Stacking‌

   Cause: PLC program errors or mechanical wear in the rotary arm.

   Resolution: Review and update PLC logic;inspect arm bearings for wear.

3. Pneumatic System Failures‌

   Cause: Air leaks or pressure fluctuations.

   Fix: Check and tighten pneumatic fittings;ensure compressor output is stable at 0.6MPa.
