what is a fully automatic palletizer?

The fully automatic palletizer is an automated equipment at the end of the production line, which neatly stacks bagged, boxed, and barreled materials on pallets according to the set stacking type. It can be connected to packaging and conveyor lines to achieve unmanned palletizing, which is widely used in the fertilizer, feed, chemical, and grain industries.

The three mainstream categories of fully automatic palletizing machines (most commonly used in fertilizer factories)

1. High level palletizer (gantry/layer palletizer)
Principle: The materials are first arranged layer by layer on the high-level grouping platform, and the entire layer is stacked in one go with a pressure bag mechanism. The bags are tightly packed without collapsing
High production capacity: bagged organic fertilizer and compound fertilizer can reach 2000-3000 bags/hour
Advantages: fast speed, orderly stacking, simple mechanical structure and easy maintenance
Disadvantages: Poor flexibility, difficult to change product specifications and machines; Large land area and sufficient floor height required; Suitable for large-scale stable production of a single product (fertilizer preferred)
2. Four axis palletizing robot (articulated robotic arm palletizing machine)
Principle: Multi joint robotic arm single point grasping, fixture can be quickly replaced (bag gripper, vacuum suction cup, clamp plate)
Capacity: 800-1200 bags/hour, capable of connecting multiple production lines simultaneously
Advantages: Strong flexibility, changing specifications only requires switching programs; Small footprint, friendly renovation of old workshops; Bags, boxes, and buckets can all be coded
Disadvantages: High speed is not as good as high speed; The maintenance requirements for reducers and servos are higher; Suitable for mixed production of multiple varieties and specifications
3. Column palletizer (low-cost and simple model)
Three axis servo column structure, X/Y/Z linear motion, low cost, simple structure
Medium production capacity, suitable for small and medium-sized factories, limited budget plan
Addendum: Collaborative palletizing robot (Cobot) does not require safety fences, has a small load capacity, and is suitable for light loads and small batches.

The overall composition of a fully automatic palletizing machine

Conveyor feeding section → Shaping and flattening mechanism (essential for bagging) → Grabbing/grouping mechanism → Tray warehouse (automatic tray supply) → Electric control+HMI touch screen → Safety protection fence matching can be added: automatic film wrapping machine, tray conveyor line, AGV docking

Suitable materials and industries for fully automatic palletizing machines

Bagged: organic fertilizer, compound fertilizer, feed, flour, cement, mineral powder (key points for your fertilizer equipment)
Packing: Food, beverage, and daily chemical cardboard boxes
Barrel/barrel material: chemical drum, lubricating oil drum
Other: woven bags, film bags, feed ton bags

The core advantages of fully automatic palletizing machine

1. Replace 4-6 palletizers to solve the difficulty of recruiting heavy bags and the risk of work-related injuries
2.24-hour continuous operation, uniform stacking type, conducive to warehousing and loading
3. Integrate packaging, screening, and coating production lines to achieve full automation of the entire line
4. HMI touch screen setting stack type, layer number, and staggered mode, easy to operate

Selection reference for fully automatic palletizing machine (fertilizer industry)

Large output, only making one type of formula fertilizer all year round → Priority given to high-level palletizers
Multiple product specifications, frequent bag changes, multiple production lines → Four axis palletizing robot
Small and medium-sized fertilizer factories with limited budgets and low output → Column palletizer

Key parameters of fully automatic palletizing machine (procurement focus)

Single bag load: commonly 25kg, 40kg, 50kg
Hourly production capacity and allowable bag size range
Tray specifications: 1200 × 1000/1100 × 1100mm
Gas source: 0.5-0.7MPa; Power supply 380V
Fixture form: Clamp bag type (fertilizer bag anti breakage bag is crucial)

Matching of fully automatic palletizing machine

Organic fertilizer production line is generally equipped with: automatic packaging scale → conveyor → fully automatic palletizing machine → film wrapping machine
