Palletizer for pellets particles grain granule powder solid
A bag palletizer is an automated or semi-automated machine designed to stack bags (such as cement, flour, fertilizer, food products, or other bulk materials) onto pallets in an organized and stable manner for storage or transportation.
Key Features of a Bag Palletizer:
Automated Stacking – Places bags in precise patterns (e.g., interlocking or column stacking) to maximize stability.
High-Speed Operation – Can handle hundreds or even thousands of bags per hour, depending on the model.
Robotic or Mechanical Arm – Some use robotic arms, while others have gantry or layer-forming systems.
Adjustable Patterns – Customizable stacking configurations (e.g., 5-bag layers, brick patterns).
Compatible with Various Bags – Works with different sizes (10–50 kg bags) and types (paper, plastic, woven polypropylene).
Integration with Conveyors – Often part of a larger packaging line, receiving bags from filling machines.
Optional Features – May include stretch wrapping, weighing systems, or pallet dispensers.
Types of Bag Palletizers:
Robotic Palletizers – Use robotic arms for flexible, high-speed stacking.
Gantry Palletizers – Use overhead cranes for heavy-duty applications.
Low-Level Palletizers – Workers feed bags at waist height for semi-automation.
High-Level Palletizers – Drop bags from above for faster operation.
Industries That Use Bag Palletizers:
✔ Construction (cement, sand, dry mix)
✔ Agriculture (fertilizer, animal feed)
✔ Food & Beverage (flour, sugar, grains)
✔ Chemicals (powdered detergents, minerals)
In the process of packaging and palletizing grains and concentrated feeds, efficient, dustproof and durable automated equipment is required to ensure production efficiency and product quality. The following are special equipment and system solutions for grain concentrated feed packaging and palletizing:
I. Key equipment in the packaging process
1. Quantitative packaging machine
Applicable materials: granular grains (corn, wheat, soybeans, peas, peanuts, melon seeds), powdered concentrated feed, mixed feed.
Equipment selection:
Electronic quantitative packaging scale (25-50kg/bag): high-precision weighing (±0.2% error), suitable for granular feed.
Valve bag packaging machine (dust-proof design): used for powdered concentrated feed (such as soybean meal, fish meal).
Open bag automatic bagging machine: used with a sewing machine, suitable for large-capacity packaging (40-80kg).
2. Sealing and marking equipment
Automatic sewing machine: sealing feed woven bags (moisture-proof and leak-proof).
Heat sealing machine: used for sealing lining film bags (such as mold-proof feed).
Inkjet printer/labeler: print production date, batch number, nutritional information table.
3. Conveying and sorting system
Belt conveyor (with dust removal device): transport packaging bags to the palletizing area to reduce dust.
Bag shaping machine: ensure that the packaging bags are flat and easy for robots to grab.
2. Core equipment in the palletizing process
Robot palletizing system (articular robot):
Features: high flexibility, suitable for multi-specification packaging (such as 20kg-50kg different bag types).
Clamp:
Plywood clamp (strong versatility, suitable for woven bags).
Suction cup + clamp combination (prevent feed bag damage).
2. Auxiliary equipment
Pallet automatic feeder: convey wooden/plastic pallets (standard size of 1200×1000mm).
Wrapping packaging machine: fix the pallet body with PE film to prevent moisture and loose bags.
Metal detector (optional): ensure that the feed is free of metal impurities.
III. Typical Workflow
Packaging Section:
Feed → Quantitative Packaging Scale → Automatic Bagging → Weighing → Sewing/Sealing → Coding → Transport to Palletizing Area
Palletizing Section:
Bags → Bag Reversal and Forming → Robot/High-Level Palletizer → Automatic Stacking → Wrapping → Finished Goods Shipped Out
