A robotic case erector automatically unfolds, forms, and bottom-seals corrugated cartons from flat blanks using a robot arm. It feeds erected cases to filling lines, boosting productivity, minimizing manual handling, and ensuring consistent output for food, pharmaceutical, and consumer product packaging.
The Robotic Case Erector is a fully automatic carton forming machine that utilises a high‑performance 6‑axis industrial robot and a flexible end‑of‑arm tool to automatically pick up flat cartons, open them, fold the bottom flaps, and seal the bottom in one continuous process. With an erecting speed of 5–30 cases per minute, it accommodates a wide range of carton sizes with tool‑free changeover. The system integrates seamlessly with mainstream PLC controls and can be easily connected to existing packaging lines. Widely used in food, beverage, e‑commerce, pharmaceutical, and daily chemical industries, the machine offers stable operation, low noise, significantly reduced labour dependence, and greatly improved packaging efficiency – making it an ideal choice for end‑of‑line automation.

Sharply Reduce Box Opening Labor Cost
Traditional production lines need dedicated workers to continuously open flat cartons, consuming heavy manpower. The box erecting machine automatically completes carton picking, unfolding and bottom locking. It replaces repetitive manual work, solves the problems of difficult recruitment and high labor expenses, and helps enterprises optimize staffing structure.
Stable High Efficiency & Continuous Uninterrupted Operation
Freed from restrictions of operator physical strength and proficiency, the equipment maintains stable box-forming speed for long-duration continuous operation. It ensures consistent supply of empty cartons for packing stations, eliminates production bottlenecks caused by slow manual box erecting, and improves overall automation line throughput.
Uniform Carton Forming & Standardized Packaging Foundation
Manual box opening often leads to skewed cartons, uneven bottom folding and loose locking. Adopting servo positioning and standardized mechanical folding structure, the machine delivers neat, square and firmly locked cartons. Stable carton shape creates favorable conditions for subsequent product loading, sealing and handling, lowering packaging abnormality rate.
Smooth Connection With Back-End Packaging Equipment
The erected empty cartons can be directly conveyed to case packers, carton sealers and other downstream machines, realizing full automatic linkage from carton unfolding, product filling to sealing. It is a key front-end device to build fully automated packaging workshops.
Wide Carton Adaptability & Convenient Size Switching
Support stepless adjustment for multiple regular carton specifications. When switching product batches, operators can finish parameter and mechanical position adjustment quickly without complicated disassembly. One machine serves multiple packaging specifications to satisfy diversified production demands.
Complete Safety Mechanism & High Operational Reliability
Equipped with carton shortage detection sensor, overloading protection and safety grating. It automatically triggers alarm and pause under abnormal conditions to prevent jamming and equipment damage. The heavy-duty welded frame and mature vacuum feeding system guarantee long-term stable running in industrial environments.
Automatic vacuum suction feeding, pick flat cartons continuously from storage bin
Automatic carton opening, bottom flap folding and interlocking forming
Adjustable mechanical structure to fit various sizes of regular corrugated cartons
Servo drive system, accurate positioning, low vibration and stable forming
Carton lack alarm function, remind operators to replenish flat cartons timely
Reserved docking interface, easy to connect with automatic packing, sealing and conveying equipment
This automatic box erecting machine serves as front-end core equipment for automated packaging lines, designed for mass continuous carton forming. It is compatible with most standard corrugated cartons and widely deployed across multiple industries:
E-commerce & Logistics Warehousing
