Material handling innovations for a better future

Material handling innovations for a better future

Material handling in manufacturing sector refers to the movement of any kind of material/load within the limits of shop floor or at the most to the transportation vehicles or warehouses.

Textile mills face a number of issues with the movement of raw materials such as cotton, yarn, and fabric from one department or machine, or floor, to another. Not only does the transportation of materials consume time and resources, but there are also various challenges in ensuring that the material is handled safely, efficiently, and economically.

Textile mill consumes a huge amount of raw material for conversion of raw material to final products. The mills are using a large number of machines and processes. During conversion of raw material to end product; material moves from one department to other, one machine to other machine and from one floor to other. Day by day, production of each machine is going up. To achieve the target of production, the mill management is facing the challenge of safe, efficient and economical material handling.

Material handling is an art and science of conveying, elevating, positioning, transporting, packaging and storing of materials, starting from the time, the raw material (such as fibres for spinning unit or yarns for weaving/ knitting unit and fabrics for wet processing or garmenting units) enters the mill gate and goes out of the mill gate in the form of finished products; it is handled at all stages within mill boundaries such as within and between raw material stores, various section of production department, machine to machine and finished product stores. A material may be handled even 50 times or more before it changes to finished product. It has been estimated that average material handling cost is roughly 10 to 30 per cent of the total production cost depending upon product to process.

By saving in the material handling cost, the cost of production can be reduced considerably. Material handling involves the movement of materials, manually or mechanically in batches or one item at a time within the plant. The movement may be horizontal, vertical or the combination of these two. Material movement adds to the cost but not to the product value. The ideal mill would have an absolute minimum of materials handling and more use of mechanical material handling equipments. The shortage of labour and increasing wages cost demand the most efficient use of labour.

Typical handling tasks are picking and orderly placing of fabric parts. Main concerns are: robust and reliable grasping of limp parts without damages and accurate positioning for the following manufacturing operations guaranteeing the quality of the final product. The development of robotic systems to carry out tasks involving soft and limp material is challenging and few reliable systems exist most of which narrowly oriented to specific tasks. Skills involved may comprise tactile and vision although material properties can be taken into account to achieve intrinsic grasping robustness.

A.T.E. has also tied up with Godrej & Boyce Mfg. (Material Handling Division) to provide effective solutions for material handling and warehouse management. This will help textile mills reduce manpower, increase the speed of material movement, improve productivity, minimise the production cost, raise handling capacity, and ensure safety.

At the time of new garment factory set up or improvising production system and factory layout, material handling system is taken into account for better factory performance and smooth material flow. A right material handling system across the factory departments reduces material transportation time, waiting time at work and delays.

Cutting table unloading is considered a reference task because it is a necessary step in an automated garment manufacturing process today and it involves all main handling issues: picking from flat a thin soft part without own stable shape, lifting up, displace, deliver to further manufacturing operations with required position accuracy and complying with quality requirements.

The robotic system is developed to carry out automatic unloading of fabric parts laid down in single layer on the stiff flat surface of a cutting table. The cut parts can be made of different material: wool, linen, cotton and artificial fibres, can have various shape, are very thin, soft and are generally porous. Attention has to be given to possible damages to the high quality garment costly material during picking and handling tasks.

Auto guided vehicles (AGVs) are the newest trend in material handling. AGVs are portable robots, which follow a prefixed path for navigation. They can tow the material stored on trailers and trolleys attached behind them or can store the material on the overhead beds for conveyance. They are used to transport loads in a manufacturing facility or a warehouse, where repetitive movement of material is required with little or no human interaction. Now a days, they are deployed in nearly every industry including automobile, food, pharmaceuticals and textiles, their scope ranging from handling raw materials to finished products.

AGVs are 100 per cent autonomous requiring no human interaction at all. Due to this the chances of errors are reduced manifolds. Unlike the traditional forklifts, pallet trucks etc they require very low maintenance. The standard AGV range at Rucha Yantra LLP includes Tugger/Tow type AGVs, Unit load carriers, Tunnel Type or Flat Bed AGVs and Mobile Assembly Conveyor AGVs. The Flat Bed AGV is the most suited product for a textile industry. It is designed in such way that it is extremely compact and low height – even less than 300 mm. This makes it very easy to slide under a trolley carrying a 100 meter cloth roll and lift it easily without requiring any manual help. It ensures completely automatic load carriage, from say spinning mill to weaving mill including automated picking and placing of the pallets, carts or trolleys.

The specialised mechanism of the AGV bed allows to transport yarns, bobbins, cloth and carpet rolls of up to 500 kg without the need of any hooking or tying. This saves manual time and effort making 100 per cent automation possible. As we know textile companies have very noisy environment due to several machines operating at the same time. The Flat Bed AGV can work seamlessly in such noisy as well as high temperature environment. Additionally, it deploys two collision detection sensors, one at front and other at rear side while ensuring complete 360 degree protection against safety incidences on factory floor. Due to inherent flexibility and accuracy, it is also ideal alternative to the heavy stationary conveyors or gantries on assembly lines occupying permanent spaces.

This flat bed AGV comes in two variants based on navigation technology requiring no floor and structural modifications – coloured path guidance technology which is three times more flexible and lower in maintenance than traditional magnetic tape or laser based navigation or a more advanced SLAM based Natural Navigation based technology which relies on static natural features in the environment and does not need additional navigation aids like tapes, reflectors, etc. This makes it easier to accommodate in the tight spaces in a textile company.

Samir Gandhi, Director of Gandhi Automations, had this to say: “The demand for material handling automation and equipment has increased exponentially over the past few years. It is because of the increasing production capacity, reducing man hours and meeting deadlines. Now with more and more companies streamlining their processes the use of material handling equipment’s for any industry is a must. The demand for such automation is the need for the hour; to deliver faster, hassle free loading/ unloading and reducing supply chain operating costs. How efficiently materials move through a manufacturing or warehouse facility will affect the cost of production as much as any other part of the supply chain. Given its importance, companies have found ways to leverage technology to improve this process. Because most manufacturing companies’ internal processes are only visible to employees, a lot of people are unaware of how common and advanced the technology involved with the many parts of the production process really is.”

He added, “In future we feel technology advancement combined with material handling equipment’s will change how logistics and supply chain management companies’ function. Looking at the current situation at hand, the future of material handling sector looks very promising as it is not just helping companies perform better but also save money whilst increasing their production capacity.
