INTRODUCTION
SCOPE OF PROJECT:
Today automation used in every industrial and many other application such as loading ,shifting the material in various application point and also transferring the material from one place to another place for saving time ,cost ,labor work, and do not cause any damage to the material while shifting the material.
Scientific automation includes integration of additional functions in the software PLC. In addition to sequential control, motion control and control technology, the software PLC also includes measurement technology and other components
INTRODUCTION ABOUT PROJECT:
In various section there is a problem of availability of space for shifting the material or transferring the material from down side to upside so we here use to shift the material from down to up by pneumatic cylinder. First off all the material is loaded on conveyor belt that loaded material moves towards the flat platform which situated on pneumatic cylinder. The pneumatic cylinder applying the pressure to move the material upward direction, then there is one another pneumatic cylinder which place horizontally in front of second conveyor belt .The second pneumatic cylinder push the material on second conveyor belt which pass the material at target point .
INTRODUCTION ABOUT CONVEYOR:
The belt consists of one or more layers of material they can be made out of rubber. Many belts in general material handling have two layers. An under layer of material to provide linear strength and shape called a carcass and an over layer called the cover. The carcass is often a cotton or plastic web or mesh. The cover is often various rubber or plastic compounds specified by use of the belt. Covers can be made from more exotic materials for unusual applications such as silicone for heat or gum rubber when traction is essential.
Material flowing over the belt may be weighed in transit using a belt weighter. Belts with regularly spaced partitions, known as elevator belts, are used for transporting loose materials up steep inclines. Belt Conveyors are used in self-unloading bulk freighters and in live bottom trucks. Conveyor technology is also used in conveyor transport such as moving sidewalks or, escalators as well as on many manufacturing assembly lines. Stores often have conveyor belts at the check-out counter to move shopping items. Ski areas also use conveyor belts to transport skiers up the hill. A wide variety of related conveying machines are available, different as regards principle of operation, means and direction of conveyance, including vibrating screw conveyors, pneumatic conveyors, the moving floor system, which uses reciprocating slats to move cargo, and roller conveyor system, which uses a series of powered rollers to convey boxes or pallets.Conveyors are used as components in automated distribution and warehousing. In combination with computer controlled pallet handling equipment this allows for more efficient retail, wholesale, and manufacturing distribution. It is considered a labor saving system that allows large volumes to move rapidly through a process, allowing companies to ship or receive higher volumes with smaller storage space and with less labor expense.Rubber Conveyor Belts are commonly used to convey items with irregular bottom surfaces, small items that would fall in between rollers (e.g. a sushi conveyor bar), or bags of product that would sag between rollers. Belt conveyors are generally fairly similar in construction consisting of a metal frame with rollers at either end of a flat metal bed. The rollers allow weight to be conveyed as they reduce the amount of friction generated from the heavier loading on the belting. Belt conveyors can now be manufactured with curved sections which use tapered rollers and curved belting to convey products around a corner. These conveyor systemsare commonly used in postal sorting offices and airport baggage handling systems.
Belt conveyors are the most commonly used powered conveyors because they are the most versatile and the least expensive. Product is conveyed directly on the belt so both regular and irregular shaped objects, large or small, light and heavy, can be transported successfully. These conveyors should use only the highest quality premium belting products, which reduces belt stretch and results in less maintenance for tension adjustments. Belt conveyors can be used to transport product in a straight line or through changes in elevation or direction. In certain applications they can also be used for static accumulation or cartons.

What Is a Permanent Magnet?
A piece of iron or steel which produces a magnetic field
Found in nature as magnetite (Fe3O4) lodestones
Magnetic field causes the permanent magnet to attract iron and some other materials
Two ends of the permanent magnet are usually designated North and South
Opposite magnet ends attract and like magnet ends repel
What Is an Electromagnet?
Electromagnets behave like permanent magnets…
… but their magnetic field is not permanent
Magnetic field is temporarily induced by an electric current
