Limitations of Material Handling : While evaluating a material handling system its disadvantages must also be considered. An effective layout involves least material handling and less costly material handling equipments. These movements do not add value to the product but they do add value to the cost Material handling is an integral part of any industrial activity. Control Principle: Control production and inventory through materials handling equipment. Conveyor belts are used for horizontal transportation. Systems Concept for Materials Handling : Systems concept for materials handling means, adopting a materials handling system from overall optimisation point of view. These principles of material handling are useful in all the fields may it be engineering, office or elsewhere.
Material Handling is concerned with motion, time, quantity and space. These periods could be long-term, or short-term in order to allow a suitable build-up of stock or finished items. This will reduce the idling of machine. These devices increase output, improve quality, speed up the deliveries and therefore, reduces the production cost. Alternative systems should then be evaluated from all angles including financial, physical, safety, acceptance by the management and operators, and its effects on working, safety and overall environment. Industrial Engineering: a Cost and economy studies, b Work-study, c Operation research, d Systems engineering, and e Facilities designing.
Functions of Materials Handling: The basic function of material handling is to choose most appropriate materials handling equipment which is safe and can fulfill material handling requirements at the minimum possible overall cost and to choose production machinery and assist in plant layout so as to eliminate, as far as possible, the need of materials handling. The plan should be developed in a team approach, with input from consultants, suppliers and end users, as well as from management, engineering, information systems, finance and operations. Various departments are located such that the material handling is minimized. Principles Related to Planning: 1. Storage space, both active and dormant, is a major consideration in any building as space costs money.
This general objective can be further subdivided into specific objectives as follows : i To reduce the costs by decreasing inventories, minimising the distance to be handled and increasing productivity. Quantity - dictates the type and nature of the material handling equipment and also cost per unit for the conveyance of the goods. Not only cost, majority of production time is also consumed in handling materials before, during and after the manufacture. Material handling equipments should periodically be resorted to check up repairs and maintenance. Material Load Oriented Systems: a Unit handling system. The materials management department can make use of one of the methods of forecasting that gives productive results to the organization. Such systems are also usually created from a variety of units.
Space requirement are greatly influenced by the Material Handling flow pattern. Material Handling has the responsibility of being sure that each location continually receives the correct quantity of parts. Economic Factors: The cost of material handling equipment, operating costs, repair and maintenance costs, taxes, insurance and depreciation costs are considered for economic analysis. To employ mechanical aids instead of manual labour to accelerate material movements. Thus, an effective control on inventory is a must for smooth and efficient running of the production cycle with least interruptions.
The components and parts can be assured for reliability by their size and dimensions within tolerance limits. Product Design and Development: The product sales can be boosted with its range and functionality. This is a large, automated device that comes complete with racks, shelves and aisles. This helps in improving the productivity. Purchasing Department: To facilitate in deciding the size of order, packaging, packing and transportation system from suppliers place to the plant. Determine, how to move the material i. A thorough survey should then be made considering the systems approach.
Their inventory control is the responsibility of the materials management department, production department and the sales department. Stores Department: Handling and storage of materials and supplies is determined by the characteristics of the items and the nature of storage methods. Equipment Oriented Systems: a Industrial Truck Systems: Platform trucks and skids, fork trucks and pallets, and tractor-trailers. In general, the functions of good materials handling system include: a Using the principles of centralization, unit load or cartelization, aim at moving optimum number of pieces in one unit. Any inefficient section creates a bottleneck that will have an effect on all other sections of the system further down the production line.
In the plant: i If materials are to be moved by hand operated or power trucks, passages are provided for their operation. Some items can be driven, while others — such as pallet trucks — simply add mobility to the materials that are being handled. On the basis of these experiences facts, systematic approach and other ideas, certain principles have been developed. These functions assist in the accomplishment of the aforesaid basic, and primary and secondary objectives of material management. Material Quality Control: The quality of the finished products manufactured will depend upon the quality of raw material used to manufacture those products. The main objective of the efficient materials handling is to decrease the costs. It is, therefore, necessary to hold inventories of various kinds to act as a buffer between supply and demand for efficient operation of the system.
Partner with the experts at Bastian Solutions to solve your automation inspection needs. Motion Principle: The handling equipment should be kept in motion i. These trucks have a variety of characteristics to make them suitable for different operations. Examples include using gravity to assist in material movement, and employing straight-line movement as much as possible. This is so since majority of production time is consumed in handling materials before, during and after the manufacture. Transporting the load, and 3. The materials handling problem must be studied at the time of planning of various machines and tools to be required and before the erection of factory building.
