YASKAWA GP50 (Payload: 50kg, Reach: 2061mm)

Process Overview

This deployment was implemented at Yuhan-Kimberly’s Chungju Plant, delivering an integrated solution that combines a Yaskawa industrial robot with a strapping-cut workbench to automate depalletizing + strap cutting.

The customer pursued a depalletizing system to reduce labor costs and operator fatigue, and showed strong interest in automating strap cutting and strap discharge to further maximize cost savings and operational efficiency.

The solution handles mixed carton sizes by aligning (squaring) cartons, cutting and removing straps, and then feeding cartons into the case packer. This improves throughput and consistency in both carton infeed and strap removal, while reducing physical strain on operators and enhancing workplace safety.

Project Background and Objectives

At Yuhan-Kimberly’s Chungju Plant, cartons arriving on pallets were previously broken down manually and then loaded one-by-one into the case packer. The work was highly repetitive, and manual strap removal using knives created a persistent risk of safety incidents.

The objective of this project was to minimize reliance on manual labor by automating the entire process—from depalletizing through case packer infeed—and to achieve lights-out (unmanned) operation for strap cutting. This enables improved operator safety, reduced fatigue and staffing burden on the floor, and more stable, repeatable plant operations.

구성요소

로봇	Yaskawa GP50 Industrial Robot: A high-speed, high-precision 6-axis articulated robot optimized for palletizing/depalletizing operations. It can automatically pick, place, and transfer a wide range of products, making it well-suited for industrial automation.
주변기기	Carton Aligner + Strap-Cutting Station: A workbench system that squares/aligns cartons of various sizes, then cuts and evacuates strapping. Safety Light Curtain + Perimeter Fence: Visually separates the operator zone from the robot cell. If an operator enters the depalletizing area, the system immediately stops motion to ensure safety.

작업순서

STEP 1.	An operator loads a pallet of stacked cartons into the designated loading position
STEP 2.	The operator selects the carton “recipe” on the HMI (OP panel) and starts the cycle
STEP 3.	The robot depalletizes bundled cartons per the selected recipe and transfers them to the alignment/strap-cutting station
STEP 4.	The station squares the bundle using servo drives and pneumatic cylinders
STEP 5.	The system cuts the straps while the cartons are securely clamped in position
STEP 6.	A hook mechanism captures and discharges the cut straps
STEP 7.	The station re-squares the bundle to prevent misalignment during cutting
STEP 8.	The robot feeds individual cartons to the case packer infeed one by one.

특장점

Key Features

Flexible handling across multiple carton sizes: Alignment and strap cutting can be performed regardless of carton size, supporting up to 27 carton size variants.
Flexible inbound conditions: Even if the number of strapped cartons on the pallet varies by load, the operator can simply enter the required conditions on the HMI (OP panel), and the robot can execute depalletizing accordingly.

Deployment Benefits

Higher productivity: Depalletizing and strap cutting are automated, increasing operation speed and reducing operator fatigue.
Lower operating cost: Process automation enables labor reduction and more efficient operations.
Improved safety: Safety light curtains, safety mats, and laser scanners help minimize accident and hazard risks during operation.

도입효과

주요지표	This depalletizing and strap-cutting automation solution deployed at Yuhan-Kimberly’s Chungju Plant delivered meaningful improvements across productivity, safety, and workforce utilization. Previously, the process required 2–3 operators to manually break down palletized cartons and remove strapping after automation, the cell could be operated with a single operator primarily monitoring the system, resulting in a labor reduction effect of over 50%.
도입기업 피드백	The customer commented, “By deploying the depalletizing robot, not only was the operator’s physical workload reduced, but logistics efficiency also improved significantly. With the safety system well implemented, operators feel more secure and can stay focused on their work.”

Yuhan-Kimberly's Choice! Fully Automated Depalletizing and String Cutting 📦

Process Overview This implementation case, implemented at Yuhan-Kimberly's Chungju factory , combines a Yaskawa industrial robot with a string cutting workstation to achieve automated depalletizing and string cutting. The client introduced the depalletizing system to reduce labor costs and work fatigue, and expressed strong interest in automating rope cutting and discharge to maximize cost savings and efficiency. This solution sorts and cuts boxes of various sizes before feeding them to the case packer, improving the efficiency of the box feeding and rope cutting processes, while also reducing the physical burden on workers and ensuring safety. Project Background and Objectives At Yuhan-Kimberly's Chungju factory , the process of dismantling palletized boxes and loading them into case packers individually was entirely manual. This process was highly repetitive and presented a constant risk of safety accidents due to the use of knives during the removal of the twine. The goal of this project was to automate the entire process, from depalletizing to loading into the case packer, minimizing human dependence. Furthermore, by unmanning the twine cutting process, we aimed to ensure worker safety, reduce fatigue and on-site personnel burden, and ensure stable plant operations.
