The main purpose of using a material handling system is to ensure that the material in the right amount is carefully delivered to the desired destination at the right time at minimum cost. The material handling system ensures the timely delivery of desired quantity of material at desired location with minimum cost and maximum safety. Material handling is not a manufacturing process but involve substantial amount of product cost and labor. Due to daily invention of new technologies material-handling equipment are undergoing continuous automation.

Wide ranges of material handling equipment are available in the market and it is difficult to select best one for industries requirement. A material handling system should be chosen in such away so that to reduce manufacturing cost and avoid interruption and damage. On the other side right selection and planning of MH improves productivity, efficiency and profit of a company.

This paper focuses on the key points of the material handling equipments. In this paper an attempt is made to set some guidelines for selecting the best material handling system for a particular task out of available ones. It is technique used to deliver the right goods safely, to the right place and time and at the right cost.

Combining the handling process means carryout other value adding processes such as Inspection, painting, cleaning while material is moving. Various material handling Equipments should be well installed and mentioned for smooth and continuous flow of material. Activity of material handling equipment before implementation first carry its criteria, specific industry match the particular product. We functions performed by MH equipment can be classified into four broad categories, that is, a transport, b positioning, c unit formation, and d storage.

Usually, all the MH functions are composed of one or more combinations of these four primary functions.

Equipment in transport category simply moves materials from one point to another, which includes conveyors, industrial trucks, cranes, and so forth. Unlike transport equipment, positioning equipment is usually employed at workstations to aid machining operations. Robots, index tables, rotary tables, and so forth are the examples of this type of equipment. Unit formation equipment is used for holding or carrying materials in standardized unit load forms for transport and storage and generally includes bins, pallets, skids, and containers.

Storage equipment is used for holding or buffering materials over a period of time. In the Asian countries like India, most of the industrial outcomes depend on automation.

Automation is the major need of any material handling system. In any industry, automation in material handling system becomes essential as it influences production rate.

A number of key words such as automation, material handling equipments and Just in Time material supply were used to search the potential literature. All rights reserved by www. In order to conduct an extensive and comprehensive search of the literature, we selected above mentioned keywords which are closely related to the objectives of our research. The modernization of automatic handling system is considered after therefore, the literature search was limited to studies published after All retrieved papers were stored and duplicates were removed.

Papers with the same titles or the same authors and same paper published in journals or conference proceedings were also removed. At the end of this process, only few papers were selected for the review study. Selection of Relevant Papers In the first stage of screening, papers written in English were scanned for keywords in the titles, abstracts and resulting 77 papers were selected for further review.

In the second stage, two investigators related to the field of automation have independently reviewed the full-text published papers for their relevance to the objective of this review. Pravin Kumar Sharma 1 The focus of this research is in the area of Selection of Material Handling Equipment in Pump industry to reduce manufacturing cycle time, and cost of manufacturing.

Various Material Handling Equipments are used in different shops of Pump industry. For selecting appropriate Material Handling Equipment, it is felt that some Multi Criteria Decision Making Methods must be used due to their ability of converting a complex problem to a paired comparison.

These methods are based on some relative Criteria and Sub-criteria. For solving these problems, some criteria Material, Move, and Method are selected.

The main conclusions drawn from this study are that, Method criteria is more important for selecting Material Handling Equipment, and Conveyor System is more efficient and accurate Equipment for Handling the Material in shop floor of any Pump industry. Today various Pump industries are present in India for manufacturing variety of Pump. In Pump Industry proper and accurate handling of material is very necessary for reducing cost of manufacturing, and manufacturing cycle time.

It is also important for increasing the capacity of production, and for improving the working conditions.

For selecting the best equipment, certain Multi Criteria Decision Making Methods based on different criteria and sub-criteria are employed. These methods based on pair wise comparison matrices and after calculating the weights of all selected alternatives, it can be concluded that, the Method criteria is more important for selecting Material Handling Equipment, and Conveyor System is more efficient and accurate Material Handling Equipment for any Pump Industry.

Nandkumar Patil 2 Material-handling system can be define as movement, handling, storage and controlling of materials throughout the manufacturing process. Helical compression springs are generally used to absorb the energy due to the impacts and to form a flexible link which deflects under loading and restore the objects to the normal position where the disturbing forces are removed.

The author concludes that, by using this material handling system we can transfer material from one place to another place without external power. This material handling equipment can save time, money and labor cost. The cost of this material handling equipment is comparatively less. In this section, we will introduce the seven basic types of MHDs. In other words, conveyors should be consid- ered only when the volume of parts or material to be transported is large and when the transported material is relatively uniform in size and shape.

Depending on the application, there are many types of conveyors— accumulation conveyor, belt conveyor, bucket conveyor, can conveyor, chain conveyor, chute conveyor, gravity conveyor, power and free conveyor, pneumatic or vacuum conveyor, 10 Materials Handling System Design roller conveyor, screw conveyor, slat conveyor, tow line conveyor, trolley con- veyor, and wheel conveyor.

Some are pictured in Figure 1. Our list is not meant to be complete, and other variations are possible. For example, belt con- veyors may be classified as troughed belt conveyors used for transporting bulky material such as coal and magnetic belt conveyors used for moving ferrous material against gravitational force.

For the latest product information on con- veyors and other types of material handling equipment, we strongly encourage the reader to refer to recent issues of Material Handling Engineering and Modern a Figure 1. These publications not only have articles illustrating use of the material handling equipment but also numerous product advertisements. With operator-friendly touch-screen con- trols, they palletize at the rate of a hundred cases per minute see Figure 1.

There are several trucks in the market with different weight, cost, functionality, and other features. Hand truck, fork lift truck, pallet truck, platform truck, counter- balanced truck, tractor-trailer truck, and automated guided vehicles AGVs are some examples of trucks see Figure 1. They are also capable of moving like the human arm and can perform functions such as weld, pick and place, load and unload see Figure 1.

Some advantages of using a robot are that they can perform complex repetitive tasks automatically and they can work in hazardous and uncomfortable environments that a human operator cannot work.

The disadvantage is that robots are relatively expensive. The first system was installed in , and the technology continues to expand. AGVs can be regarded as a type of specially designed robots. Their paths can be controlled in a number of different ways. They can be fully automated or semiautomated. AGVs are becoming more flexible with a wider range of applications using more diverse vehicle types, load transfer techniques, guide path arrangements, controls, and control interfaces.

They can also be embedded into other MHDs. A sample of AGVs and their applications are illustrated in Figure 1. Because the space above the machines is typi- cally utilized only for carrying power and coolant lines, there is abundant room to transport bulky material. The movement of material in the overhead space does not affect production process and worker in a factory. However, they offer a number of advan- tages, such as low labor and energy costs, high land or space utilization, high reliability and accuracy, and high throughput rates.

Wallace Products Corp. For example, decreasing the number of Figure 1.

The methodology illustrated in Figure 1. All these six questions are extremely important and should be answered satisfactorily. Very often, when the material and move aspects are analyzed thoroughly, it automatically uncovers the appropriate material handling method. For example, analysis of the type and characteristics of material may reveal that the material is a large unit load on wooden pallets.

This suggests that a fork lift truck would be a suitable material handling device. Even further analysis of the method may tell us more about the specific features of the fork lift truck.

Apple, Jr. Most of the studies have focused on material handling equip- ment optimization, rather than the entire material handling system. Sujono and Lashkari proposed a multiobjective model for selecting MHDs and allo- cating material handling transactions to them in flexible manufacturing system FMS design.

Their study is an extension of the Paulo et al. The main differences from the previous mod- els are the new definition of the variables and the introduction of a new variable that links the selection of a machine to perform manufacturing operation with the material handling requirements of that operation. In addition, they include all the costs associated with material handling operations and suboperations, and the complete restructuring of the constraints that control the selection of the material handling equipment and their loading, in the objective function.

Their model is presented as follows.

A 5 for Wet means that the piece of equipment is best suited to handle parts with a very high rating of product variable t. A 0 means, do not allow this piece of equipment to handle parts with product variable t.

And a 0 means that the part type exhibits a very low level of the key product variable t. The second part of the objective function computes the overall compat- ibility of the MH equipment. As a result, the formulation of the problem is a multiobjective model seeking to strike a balance between the two objectives.

There are nine constraints in this model: 1. They are involved in various stages of the sourcing, production, and distribution of goods, from raw materials through the finished goods.

The true value of ware- housing lies in having the right product in the right place at the right time.

Thus, warehousing provides the time-and-place utility necessary for a company and is often one of the most costly elements. Therefore, its successful management is critical. Because additional paperwork and time are required to store items in storage spaces and retrieve them later when needed, the JIT manufacturing phi- losophy suggests that one should do away with any kind of temporary storage and maintain a pull strategy in which items are produced only as and when they are required.

That is, they should be produced at a certain stage of manufacturing, only if they are required at the next stage. JIT philosophy requires that the same approach be taken toward components received from suppliers.

The supplier is considered as another previous stage in manufacturing. However, in practice, because the demand is continuous, that means that goods need to be always pulled through the supply chain to respond to demand quickly. The handling of returned goods is becoming increasingly important e. In many cases, the need to provide better 6 Warehousing 25 service to customers and be responsive to their needs appears to be the pri- mary reason. To achieve economies of scale in production, transportation, and handling of goods, it is often necessary to store goods in warehouses and release them to customers as and when the demand occurs.

Goods are received from order picking stock in the required quantities and at the required time to the warehouse to meet customer orders. For example, goods can be received from suppliers as whole pallet quantities, but are ordered by customers in less than pallet quantities.

In some cases, warehouses ship goods to customers and therefore are in direct contact with them. So, a ware- house can serve as a customer service facility and handle replacement of damaged or faulty goods, conduct market surveys, and even provide after sales service. For example, many Korean electronic goods manufac- turers let warehouses handle repair and do after sales service in North America. Sometimes manufactured goods are stored in warehouses to protect them against theft, fire, floods, and weather elements because warehouses are generally secure and well equipped.

Safety codes may not allow storage of hazardous materials near the manufacturing plant. Because no manufacturing takes place in a warehouse, this may be an ideal place to segregate and store hazardous and contaminated materials.

In many warehouses after picking, goods are brought together and consolidated as completed orders ready to be dispatched to customers. This can involve packing into dispatch outer cases and cartons, and stretch- and shrink- wrapping for load protec- tion and stability, inspecting, and testing.

Here, inspection and testing do not add value to the product. Reach mechanisms and outrigger arms that straddle and support a load can be used in addition to the just the counterbalance of the truck. On a turret truck, the forks rotate during stacking, eliminating the need for the truck itself to turn in narrow aisles. An order picker allows the operator to be lifted with the load to allow for less-than-pallet-load picking. Automated guided vehicles AGVs are industrial trucks that can transport loads without requiring a human operator.

Positioning equipment is used to handle material at a single location. As compared to manual handling, the use of positioning equipment can raise the productivity of each worker when the frequency of handling is high, improve product quality and limit damage to materials and equipment when the item handled is heavy or awkward to hold and damage is likely through human error or inattention, and can reduce fatigue and injuries when the environment is hazardous or inaccessible.

Material-handling equipment

Unit load formation equipment is used to restrict materials so that they maintain their integrity when handled a single load during transport and for storage. If materials are self-restraining e. A pallet is a platform made of wood the most common , paper, plastic, rubber, or metal with enough clearance beneath its top surface or face to enable the insertion of forks for subsequent lifting purposes.

Storage equipment is used for holding or buffering materials over a period of time. The design of each type of storage equipment, along with its use in warehouse design, represents a trade-off between minimizing handling costs, by making material easily accessible, and maximizing the utilization of space or cube. The use of racks becomes preferable to floor storage as the number of units per item requiring storage decreases.

Similarly, the depth at which units of an item are stored affects cube utilization in proportion to the number of units per item requiring storage. Pallets can be stored using single- and double-deep racks when the number of units per item is small, while pallet-flow and push-back racks are used when the units per item are mid-range, and floor-storage or drive-in racks are used when the number of units per item is large, with drive-in providing support for pallet loads that cannot be stacked on top of each other.Standardization means less variety and customization in the methods and equipment employed.
