Material Handling • The primary material handling objective is to efficiently move large quantities of inventory into the factory and finished goods out of the factory /warehouse and also facilitate movement within the factory • Handling is divided into • Receiving • In storage handling • Shipping Material handling is the short distance movement that takes place in or around a building such as plant or warehouse.
Unloading the incoming material from transport vehicle • Moving the unloaded material to assigned storage place in the factory • Lifting the material from storage place during order picking • Moving material for inspection, packing, from 1 machine to another • Loading the boxes / cartons on to transport vehicle Material Handling Stages
Objectives Of Material handling- • To increase the cube utilization by using the height of the building and reducing the need for aisle space as much as possible. • To improve operating efficiency increase of load per move will result in fewer moves • To improve the service levels by increasing the speed of response to customer needs • Reduce the manufacturing cycle time through faster movement of materials • Contribute to the better control of flow of material in the factory • Safety in movement of the materials
Specialized handling equipment is required for loading/unloading bulk materials such as for solids, fluids, or gaseous materials. The guidelines/principles of material handling systems are: • Equipment for handling and storage should be as standardized as possible. • When in motion, the system should provide maximum continuous flow.. (c) In selecting handling equipment, the ratio of deadweight to payload should be minimized. • Whenever possible, gravity flow should be incorporated in the system design. • Reduce handling as much as possible • The handling systems can be classified as under: - Manual • Mechanized • Semi automated • Automated Detailed Information refer http://dcm-reality.blogspot.in/
Material Handling Manual Trolley Versatile For smaller loads For short distance
Mechanized Systems • Forklift Trucks • Forklift trucks can move loads of master cartons both horizontally and vertically. • A pallet or slip sheet forms a platform upon which master cartons are stacked. • Most effectively utilized in shipping and receiving and placing merchandise in a predetermined storage space. • Common sources of power are propane gas and electricity. B Cranes C Conveyors • Conveyors are classified according to power, gravity or roller/belt movement. • Portable gravity style roller conveyors are often used for loading and unloading. .
Forklift • Manual or mechanized • Portable • Large distance travel • Medium & large loads handling • Vertical movement Material Handling (mechanised)
Overhead Crane Carry heavy loads Continuous duty Size shape no bar Material Handling
Semi automated system supplements a mechanized system by automating a specific handling requirements. Semi automated material handling is a mixture of mechanized and automated handling. • Automated-Guided Vehicle Systems • Performs similar kind of handling function as a mechanized tow tractor with a trailer. • The essential difference is that an AGVS does not require an operator and is automatically routed and positioned at destination with intervention of the operator. • Typical AGVS equipment relies on an optical or magnetic guidance system. • In the optical application, tape is placed on the factory/warehouse floor, and the equipment is guide by a light beam that focuses on the guide path. • A magnetic AGVS follows an energized wire installed in the floor. • The primary advantage is the elimination of a driver and newer AGVS use video and information technology to follow paths without the need for fixed tracks.
Automated Handling • Though operates faster and more accurately, requires high degree of capital investment and complex to operate. • Most automated systems are custom deigned and constructed for each application. • The system is connected to the computer for programming the equipment operations material pickup route packing and loading instructions Automatic Storage and Retrieval System (ASRS) • High rise handling systems are fully automated from . • The components of this system are storage racks, storage and retrieval equipment and control systems. • The high rise are the vertical storage racks up to the height of 120 feet. The storage and retrieval machine travels back and forth with the primary objective of moving products in and out of storage.
