MATERIAL HANDLING AND STORAGE SYSTEM[1]
Defined as the art and science of moving, packing and storing of substances in any form.
Also MH and Storage is the efficient short-distance movement of goods that usually takes place within the confines of a building such as a plant or a warehouse or between a building and a transportation agency.
OBJECTIVES[1][2]
Main objective is to reduce the number of units as well as the overall cost of material handling and equipment and reducing the distances through which the materials are handled or storage.
The other objectives:- To provide better control of the flow of materials. Lower unit material handling and storage costs. Improved working conditions and greater safety in
movement of materials.
IMPORTANCE OF MATERIAL HANDLING AND STORAGE SYSTEM[2][3]
Material Handling and storage are increases effectiveness of in plant layout by reducing the cost.
These movements do not add value to the product but they do add value to the cost.
Function of production control.Concerned with scheduling of production
control.
Factors affecting the Selection of Materials Handling& Storage Equipment
Production problem
Human element involved
Capabilities of the handling equipment available
AFFECTING FACTORS[3]
Production ProblemVolume of Production to be
maintained
Layout of plant & building facilities
Class of materials to be handled
Equipments
Factors
Adaptability
Speed
Space requirements
Supervision required
EnvironmentCost
Ease of Maintaince
Power
Load capacity
Flexibility
TYPES OF MATERIAL HANDLING AND ITS EQUIPMENTS[4]
1. Equipments oriented systems a) Convey or Systemsb) Fork lift truck c) Industrial truck system
2. Material Oriented Systemsd) Unit handling systeme) Bulk handling systemf) Liquid handling system
EquipmentsConveyors
◦ Belt conveyors, Chain conveyors, Roller conveyors, bucket conveyors, screw conveyors, pipeline conveyors, vibratory conveyors, chute or gravity conveyors.
Cranes, Elevators and Hoists◦ Cranes – overhead rails or ground rails or
wheels◦ Elevators – between floors – vertically◦ Hoists - vertically, horizontally – limited area –
electric or chain hoist
Roller Conveyor- Boxes , large parts or units loads roll on top of a series of rollers mounted on a rigid frame.
These are overhead devices used for moving varying loads intermittently between points within an area.
2. Cranes, Elevators and Hoists
Cranes – Devices mounted on overheard rail or ground wheels or rails .They lift, swing and transport large and heavy materials
TYPE OF STORAGE SYSTEM AND ITS EQUIPMENTS[4]
Automated storage and retrieval system(ASRS or AS/RS):-
An automated storage and retrieval system (ASRS or AS/RS)
consists of a variety of computer-controlled methods for
automatically placing and retrieving loads from specific storage
locations.
An automated storage/retrieval system (AS/RS) is a storage system
that performs storage and retrieval operations with speed and
accuracy under a defined degree of automation.
Equipments
Products such as pallet racking, shelving, carts, etc. belong to storage.
A pallet is the structural foundation of a unit load which allows handling and storage efficiencies.
HOUSEKEEPINGStorage areas must be kept free from accumulation of
materials that create hazards from:
◦ Tripping
◦ Fire
◦ Explosion
◦ Pest harborage
ESSENTIAL OF GOOD MATERIAL HANDLING OR STORAGE SYSTEM[1][2]
Efficient and safe movement of materials to the desired place.
Timely movement of the materials when needed.
Supply of materials at the desired rate.Storing of materials utilizing minimum space.Lowest cost solution to the materials
handling activities.
DISPOSAL OF WAST MATERIAL[5]
An enclosed chute must be used
when dropping material more than
20 feet outside of a building.
When debris is dropped through
holes in floors without the use of
chutes.
Area must be enclosed with
barricades.
Warning signs must be posted at
each level.
ENVIRONMENTAL CONDITIONS[6]
