Manipulator for Instant Noodle Packaging Film Rolls

In instant noodle manufacturing plants, the process of changing packaging film rolls is one of the factors directly affecting packaging productivity. Heavy BOPP/CPP film rolls not only pose challenges for lifting and installation but also increase machine downtime, the risk of occupational accidents, and material damage rates.

To solve this problem, lift assist manipulators are becoming the solution chosen by many businesses. With automatic load-balancing technology, the device helps lift and lower film rolls quickly, accurately, and safely, thereby optimizing OEE (Overall Equipment Effectiveness), reducing operating costs, and building a more modern working environment.

Challenges in manual film roll loading

Modern instant noodle packaging lines can operate at speeds of hundreds of packets per minute. However, the efficiency of the entire system will be significantly affected if the film roll changing and loading process cannot keep up with the production pace. Handling film rolls manually not only increases machine downtime but also entails many risks regarding safety, quality, and operating costs. Below are common challenges that factories frequently face:

Risk of Musculoskeletal Disorders (MSDs)

BOPP/CPP film rolls used in the instant noodle industry usually weigh from 20 kg to over 150 kg. During the roll change process, operators must perform lifting, rotating, pushing, and aligning actions in awkward postures, requiring significant physical effort and continuous repetition.

In the long term, this increases the risk of musculoskeletal disorders (MSDs) such as back pain, herniated discs, spinal degeneration, and shoulder or wrist injuries. This is also one of the common causes leading to a decline in labour productivity and an increase in costs related to occupational health and safety.

Increased downtime, affecting OEE

In a continuous production environment, every minute of downtime directly affects output. When changing film rolls manually, workers often spend a lot of time lifting, moving, and precisely aligning the roll core onto the packaging machine shaft.

This process not only prolongs roll change time but also increases downtime, causing production interruptions and reducing the Overall Equipment Effectiveness (OEE) index of the line.

Increased risk of material damage and waste generation

Packaging film is a high-value material and highly sensitive to mechanical impacts. During manual lifting or when using non-specialised support equipment, film rolls are prone to incidents such as collisions, dented paper cores, surface scratches, or telescoping.

These damages not only affect packaging quality but can also cause the entire film roll to be discarded, increasing raw material costs and the scrap rate in production.

Pressure on human resources and operating costs

The job of changing film rolls often requires the coordination of 2–3 people, along with certain health and experience requirements. The strenuous and potentially risky nature of the work makes it difficult for many businesses to recruit and retain personnel for this position.

Besides direct labor costs, businesses also face training costs, replacement personnel costs, and the risk of production interruptions when there is a shortage of experienced labor. This is a significant management challenge for factories aiming for a lean and efficient production model.

Lift Assist Manipulators: A breakthrough solution for instant noodle packaging machines

To overcome the limitations of manual lifting methods, more and more food and packaging factories are choosing to apply lift assist manipulators in the film roll changing process. This is not just an ordinary lifting device but a smart assist system designed to support operators in handling heavy loads safely, accurately, and efficiently.

Thanks to automatic load-balancing capability combined with specialized gripping mechanisms, the manipulators make lifting, moving, and installing film rolls easier, while significantly reducing downtime and the risk of material damage.

Zero Gravity Technology – Near-weightless lifting

The highlight of modern manipulators lies in their Zero Gravity (automatic load balancing) technology. The system automatically detects and precisely balances the weight of the film roll, keeping the load stable throughout the operation.

Unlike traditional electric hoists that must be controlled by buttons, operators can directly manipulate the load by hand with very little force. Even film rolls weighing tens to hundreds of kilograms can be lifted, lowered, pulled, pushed, or rotated gently and accurately.

As a result, aligning the film roll into the correct position on the packaging machine shaft becomes faster, significantly reducing installation deviations and minimizing the risk of collision during operation.

Specialized gripping mechanisms for packaging film rolls

Each type of film roll has different sizes, weights, and core structures. Therefore, manipulators can be equipped with various specialized gripping mechanisms to ensure safe lifting and maximum material protection.

Expanding Mandrel

• This is the most common and effective solution for BOPP/CPP film rolls. The gripping mechanism is inserted inside the roll core; then the jaws expand and securely fix it from the inside.
• This method helps keep the film roll stable during lifting without contacting the material surface, minimizing the risk of scratches, deformation, or telescoping.

External gripper with protective pads

• For film rolls not suitable for the core gripping method, the system can use an external gripping mechanism with precisely controlled clamping force.
• Contact surfaces are equipped with specialized pads that protect the paper core and the film roll surface, while maintaining stability during movement and installation.

Flexible for any factory layout

One of the outstanding advantages of manipulators is their customizability according to the actual conditions of each factory.

• Floor-mounted manipulators: The device is installed on a fixed column, suitable for areas with wide workspaces or needing to serve multiple packaging machine positions within the same operating zone.
• Ceiling-mounted manipulators: The system is suspended on aluminum or steel rails above the production area, completely freeing up floor space. This is a suitable choice for factories with high equipment density or those requiring optimized movement flows for forklifts and personnel.

Thanks to the ability to design flexibly according to the actual layout, lift assist systems can be easily integrated into existing lines without affecting production activities, while contributing to building a more modern, safe, and efficient working environment.

Economic benefits of applying manipulators

Investing in a manipulator system is not just about equipping an additional lifting device, but a solution to comprehensively optimize the loading process on the packaging line. The values brought can be measured directly through productivity indicators, operating costs, and the level of occupational safety in the factory.

Increase roll change speed, improve equipment effectiveness (OEE)

In a continuous production environment, machine downtime for film roll changes is one of the factors directly affecting output productivity. With automatic load-balancing technology, manipulators help operators perform lifting, moving, and installing operations for film rolls faster and more accurately than manual methods.

Roll change time is significantly shortened, contributing to reduced downtime and maintaining stable operation of high-speed packaging machines. As a result, businesses can improve their Overall Equipment Effectiveness (OEE) index, optimize line capacity, and enhance their ability to meet production plans.

Optimize operating costs and improve investment efficiency

Besides productivity benefits, manipulators also bring clear economic efficiency in the long term. Reducing dependence on manual labor helps businesses save labor costs, while limiting incurred expenses related to workplace accidents, resignations, or training replacement personnel.

In addition, precise operation capabilities minimize the risk of damaging film rolls, reducing scrap and raw material losses. These are important factors that help shorten the payback period and increase investment efficiency for businesses.

Build a safe and ergonomic working environment

Instead of directly supporting film rolls weighing tens or hundreds of kilograms, operators only need to control the device with very little force. The entire load is received and balanced by the assist system throughout the operation.

This helps eliminate heavy lifting movements, reduces the risk of musculoskeletal disorders (MSDs), and significantly improves working conditions for employees. A safer and friendlier working environment also contributes to improving employee engagement and reducing staff turnover rates in the factory.

Minimize material damage and improve production quality

Specialized gripping mechanisms are designed to suit the characteristics of packaging film rolls, helping to keep the load stable throughout lifting and installation. As a result, the risk of impact, core denting, surface scratching, or telescoping is minimized.

Better control of input material quality not only reduces scrap but also contributes to maintaining the stability of the packaging process, ensuring finished product quality and reducing production costs.
