3. Overview of previous lecture Bulk material handling –Definition, examples, applications Bulk material handling equipments –Belt conveyer (Principle, uses/ application, types, material, design considerations) –Bucket elevator/ bucket conveyer (Principle, types, applications) –Screw conveyers (definition, principle, types etc.) –Vibratory conveyers (definition, working principle, applications, advantages) –Material feeding and metering methods (uses, devices)

4. © mmjan 2014 Bulk Material Handling Vehicle bulk conveyor systems –Such systems consist of conveyors that can be moved easily so that they can be used for loading and unloading of bulk material from vehicles like Trucks Rails Aircrafts

5. © mmjan 2014 Bulk Material Handling Vehicle bulk conveyer systems –Consists of Conveyer systems (belts, rollers etc.) Driving mechanism (motor, gears, pulleys etc.) Control cabinet (electronics, sensors, transducers etc.) Transportation modes (wheel carriages, trucks etc.)

8. © mmjan 2014 Marine Bulk Material Handling Marine handling equipments –Those equipments which are used for handling of material related to sea or ocean –These may include transportation to or from Directly from sea From islands Ships Ports –Marine equipments handling are also used in material stockyards

9. © mmjan 2014 Marine Bulk Material Handling Products associated with marine may include –Mining (coal, iron, sulfur, etc.) –Import export bulk materials (grains, wheat, etc.) –Chemical plants (chemical processing) –Petroleum products –Food products –Ship breaking industries

10. © mmjan 2014 Marine Bulk Material Handling Material handling equipments is performed by –Cranes –Conveyers –Elevators –Rails –Containers –Lifters

18. © mmjan 2014 Packaged material handling Packaged materials are those materials that cab be easily packed in single units Few examples are –Food items –Medicines –Glassware –Industrial products –Electronics

19. © mmjan 2014 Packaged material handling Pallets and palletizing operations –These are unit load formation equipments –The objective is to use recyclable material for the product containers –Such material handling consist of Boxes Cartons Crates Totes Bags Packets

20. © mmjan 2014 Packaged material handling Pallets –Pallets are probably the most common platform for moving unit loads. –Perhaps the most obvious area of concern associated with the use of pallets today involves cost and quality –Poor quality pallets annually cost industry billions of dollars in the form of Product damage, Lost productivity, and Damaged handling

21. © mmjan 2014 Packaged material handling Pallet construction –A pallet consist of Top deck/ slat Bottom deck/ slat Blocks Stringer board (support/ connector) Plates Guide ways for fork liter forks Guide ways for hand-trucks forks

22. © mmjan 2014 Packaged material handling

23. © mmjan 2014 Packaged material handling Pallet construction –Size of pallet is specified by its depth (i.e., length of its stringers or stringer boards) and its width (i.e., length its deckboards)—pallet height (typically 5 in.) is usually not specified – 48 × 40 in. (1200 × 1000 mm) pallet is most popular in the US (27% of all pallets—no other size over 5%) because its compatibility with railcar and truck trailer dimensions; e.g., the GMA (Grocery Manufacturers of America) pallet is four-way and made of hardwood –1200 × 800 mm “Euro-Pallet” is the standard pallet in Europe –Single-face pallets are sometimes referred to as “skids”

24. © mmjan 2014 Packaged material handling Pallet material –A key decision affecting the overall life cycle cost of pallets is the materials used in their manufacture –The pallet materials include Wood Pressed wood fiber Corrugated fiberboard Plastic Metal

25. © mmjan 2014 Packaged material handling Wooden pallets Corrugated fiberboard

26. © mmjan 2014 Packaged material handling Pressed wood fiber pallets

27. © mmjan 2014 Packaged material handling Plastic pallet Metal pallet

28. © mmjan 2014 Packaged material handling Advantages of using different material pallets –Wooden pallets are sold each year than any other type due to the versatility, low cost, biodegradability and recyclability of this material –Pressed wood fiber is a combination of wood fibers and organic resins which eliminates the need for nails and enables the molding of pallets into more space efficient designs

29. © mmjan 2014 Packaged material handling Advantages of using different material pallets –Disposable, corrugated fiberboard pallets can be made of recycled paper materials and provide a light weight, low cost alternative for one way shipping when loads do not need to be stored outdoors –Durable plastic and metal pallets may provide the low cost alternative over the full pallet life cycle despite their high initial cost Both of these materials are recyclable, can be sanitized for clean applications, and can be used in the most demanding applications

30. © mmjan 2014 Packaged material handling Some of the tradeoffs associated with different pallet construction materials medicines agriculture

31. © mmjan 2014 Packaged material handling Palletizing –It is the process of stacking the product to form a unit load –Palletizing operation may be through the following methods Manual Automated /robotic

32. © mmjan 2014 Packaged material handling Manual palletizing

33. © mmjan 2014 Packaged material handling Automated/ robotic method

34. © mmjan 2014 Packaged material handling Pallet positioner –It is a tool which fulfills the ergonomics requirements of an operator –It consist of a turn-table, drive mechanism, damping system and control device –It can be operated Manually Hydraulically Motorized
