Q.1

Can Crusher:

A can crusher is a device used for crushing aluminum soda, soft drinks and beer cans for easier storage in recycling bins. Most of the recyclers don’t require you to crush cans, if you do recycle a lot, your normal bin may fill up quickly. The can crusher gives you extra space by flattening either single or multiple cans. The first can crusher was of course the human foot. People often stomped on cans to flatten them down either for recycling or for greater space in the garbage can. This could sometimes hurt if the foot did not come down properly on the can. But now there are lot of can crushers available in the market. The simplest, usually about 10 US dollars (USD) have you crush a single can at a time, by pulling on a lever that brings weight down on the can until it is crushed nearly flat. For about 20 USD you can find can crusher devices that will flatten numerous cans at the same time. This type of can save time, especially if crushing the can by hand.

Features of can crusher:Can crushers are powered by different methods, but all share similar features. Cans are deposited or placed into a chamber outfitted with a device that crushes the cans. The device can be a disk that smashes the cans from above, a metal unit that gives the cans a two-sided "hug" to crush them, or a massive, mechanical chamber that crushes cans on an assembly line.

Various type of Can Crushers available in the market:-

Can crushers have become important item these days. It is commonly used for the purpose of smashing and flattening soda cans. However, nowadays, it is used for various other purposes as well. Many people prefer to have beverages in aluminum cans.A can crusher helps in recycling of hard metals like aluminum. It not only saves space but time and money too. In the market, we can find both plastic and metal can crushers, sometimes even a mixture of both. Such devices made of recycled plastics arealso available in the market, these are environment friendly. Hand and foot can crushers are manually functioned, but ones operated by foot are definitely easier and of fun. Here it should be mentioned that hand can crusher work in a more organized way and does not create a mess as the ones done by foot do.

Can crusher can be of many types according to how they works; it can be mechanical, hydraulic, pneumatic and magnetic. Hydraulic can crusher work without the use of water and certainly are devoid of any sound or calibrations. But mostly the ones we commonly find in the market are electronic. There are various companies like Ontario limited, Alan Ross Machinery Corporation, Can Cycler equipment, Inc, etc. that have steadily taken up this recycling objective through the products that they sell, and can crusher is one of them.

The various types of can crushers is given below:

I. Hand Operated Can Crusher:

This type of can crusher is operated by hand manually. These type of can crusher made of wood and metal or plastic also.

Q.3

Material consideration and their properties:

I. Cast iron:Cast iron is an alloy of iron and carbon, and is popular because of its low cost and ability to make complex structures. The carbon content in cast iron is 3% to 4.5% by weight. Silicon and small amounts of Manganese, Sulfur, and Phosphorus are also present in it. The products of cast iron exhibit reasonable resistance against corrosion. It is neither malleable nor ductile, and it cannot be hardened like steel. It melts at about 2100 ºF, and has either a crystalline or a granular fracture.

Types of cast iron:

white iron grey iron ductile iron malleable iron

Properties of Cast iron are:

Tensile Strength:Different varieties of cast iron are used in the construction of machines and structures. Cast iron having a tensile strength of 5 tons per square inch, or less, is of no value for the purpose where strength is required. This type may however be used for balance weights, foundation blocks, or for purposes where weight alone is of consequence. Some varieties of cast iron show a tensile strength as high as 19 tons per square inch, but on an average, the strength is 7 tons per square inch. Addition of vanadium can increase the strength of cast iron.

High Compressive Strength:Compressive strength is defined as the ability of a material to withstand forces which attempt to squeeze or compress it. Cast iron shows high compressive strength, which makes it desirable for use in columns and posts of buildings. The compressive strength of gray cast iron can be almost as high as that of some mild steels.

Page 25: Can crusher file by Rohit Dhiman

Course work -2|25

Low Melting Point:Its melting temperature ranges from 1140 ºC to 1200 ºC. Nowadays, many advanced melting, alloying and casting methods are being used, which can bring the new irons formed, in competition with steel.

Resistance to Deformation:Cast iron structures show resistance to deformation and provide a rigid frame. However, if one part of the casting after the iron is poured into the molds, is very thin, and another very thick, the problem of the structure breakdown becomes prominent. The reason for this is when the thin part cools first and contracts, the thick part which cools down afterward causes stress in the thin part, offering sufficient force to break it.

Resistance to Oxidation:Rust is formed by the reaction of iron and oxygen, in the presence of water or air moisture. It leads to the corrosion of iron and its alloys, and any iron mass in presence of water and oxygen, can eventually convert into rust and later disintegrate. As cast iron offers resistance to oxidations, it provides a solution to the problem of rust.

Specification of cast iron:

Density 7.8 g.cm-3 at 20°CMelting point 1536 °CBoiling point 2861 °CAtomic mass 55.85 g.mol -1

Heat of fusion 13.81 kJ·mol−1

II. Steel:Steel is composed primarily of iron with carbon as the major alloying element. The greater the percentage of carbon, the stronger and stiffer the steel. High-carbon steels are generally infeasible for use as workpiece materials in sheet metal forming because of their high resistance to permanent or plastic deformation. Most automotive stampings are produced from low-carbon steel, containing less than .15% carbon. In some applications resistance to plastic deformation is desired, e.g., in springs.The type of steel are given below:

Page 26: Can crusher file by Rohit Dhiman

Course work -2|26

Cold Rolled Steel As with most metals the alloy composition, heat treatment and any mechanical processing (rolling in this case) are all important in determining material behavior. The "drawing quality" steels are processed to produce uniform deformation up to large deformations (deformation and uniform deformation is discussed in detail below). One such deformation behavior improving process is used in "aluminum killed" steel. Aluminum is used to remove oxygen from the steel and so minimize the deleterious effects of oxygen on the extent of deformation which can be imposed and on the uniformity of deformation. Steels are available in 1/4 hard, 1/2 hard and full hard conditions.

Spring Steel has a high "elasticity," that is, a large amount deformation can be imposed before the material takes on a permanent set or plastic deformation is produced. These ideas are covered in detail below.

Stainless Steels contain alloying additions of nickel and chromium. Their cost is high,but because of their fine surface appearance and resistance to corrosion, they are used in forming special parts. Stainless steels with various heat treating tempers are commonly available.

Properties of steel:

Strength

Yield strength:Yield strength is the most common property. The primary designation relates to the yield strength, e.g. S275 steel is a structural steel with a specified minimum yield strength of 275 N/mm².

Toughness:

It is in the nature of all materials to contain some imperfections. In steel these imperfections take the form of very small cracks. If the steel is insufficiently tough, the 'crack' can propagate rapidly, without plastic deformation and result in a 'brittle fracture'. The risk of brittle fracture increases with thickness, tensile stress, stressraisers and at colder temperatures. The toughness of steel and its ability to resist brittle fracture are dependent on a number of factors that should be considered at the specification stage.

Page 27: Can crusher file by Rohit Dhiman

Course work -2|27

Ductility:-

Ductility is a measure of the degree to which a material can strain or elongate between the onset of yield and eventual fracture under tensile loading.

Weldability:-

All structural steels are essentially weldable. However, welding involves locally melting the steel, which subsequently cools. The cooling can be quite fast because the surrounding material, e.g. the beam, offers a large 'heat sink' and the weld is usually relatively small. This can lead to hardening of the 'heat affected zone' (HAZ) and to reduced toughness. The greater the thickness of material, the greater the reduction of toughness.

Specification of steel:

Modulus of elasticity, E 210,000 N/mm²Shear modulus, G E/[2(1 + ν)] N/mm², often taken as

81,000 N/mm²Poisson's ratio,v 0.3Coefficient of thermal expansion, α 12 x 10-6/°C (in the ambient temperature

range).

Q.5

Assembling of Can Crusher: In the assembly of can crusher various manufacturing processes are involved which are given below:

1. The first step is draw the free hand sketch of the model on the paper to ensure that the concept will be successful. After this, the sketched model is converted into solid modelingand drawing using solidworks.

2. I collect the raw material for the can crusher such as angle arms for base, sheet metal for the hood of gearbox, bushes for providing support to the two rotating shafts, gears, handle for operating.

3. The next step is the measuring and marking of the material with the help of a vernier caliper, measuring tape and try square for flatness checking. Scriber is used for the marking.

4. After measuring and marking the extra material removed by machining from the work piece with the help of lathe machine. Cutting of the raw material with the help of power hacksaw.

5. After cutting process, the base frame of the can crusher is made with angle arm by the welding process. The legs of the base have a washer welded to the bottom for the purpose of mounting on table.

6. On the base frame, I place a cylinder or sleeve having a two cuts one is on top, for inserting cans and other is on the bottom for the ejection of crushed can automatically. The sleeve is mounted on the base frame with the help of nuts and bolts.

7. After sleeve mounting, a gear box pillers are made with angle arms and welded on the base frame. The two bushes are mount on the base frame and two are mount on the piller of the gearbox. The driven(crank shaft) shaft moves in base frame lower brushes and the driving shaftmoves in upper

bushes. The driven(crank) shaft is fitted with balance weight which provides smooth reciprocating motion to the piston and takes less effort of worker.

8. The driving gear(pinion)is welded on the driving shaft and the driven (bull)gear is welded on the driven(crank) shaft. The two gears are chain wheel gears and the power is transmitted by the chain from the driving gear to driven gear. The driving power is given by the handle manually, the handle is mounted on the driving shaft with the help of nut and bolt.

9. On the sleeve upper cut a hopper is welded made of round iron bars. The purpose of hopper is to hold the auxiliary cans.

10.The piston is placed in the sleeve and join to the crank shaft with the help of connecting rod. The piston face is tapered from front, this provides automatic lift to the another can and prevent the can from bending.

11.The gearbox is covered with the sheet metal hood or cover and hinge on one

Automation and Further Modifications In Can Crusher:

Page 43: Can crusher file by Rohit Dhiman

Course work -2|43

Automation:Automation is the use of machines, control systems and information technologies to optimize productivity in the production of goods and delivery of services. The correct incentive for applying automation is to increase productivity, and/or quality beyond that possible with current human labor levels so as to realize economies of scale, and/or realize predictable quality levels.

Advantages of automation:The main advantages of automation are:

Increased throughput or productivity. Improved quality or increased predictability of quality. Improved robustness (consistency), of processes or product. Increased consistency of output. Reduced direct human labor costs and expenses.

Application and purpose of automation:

Automation used in operations to reduce cycle time. Automation is used where a high degree of accuracy is required. Replacing human operators in tasks that involve hard physical or

monotonous work. Replacing humans in tasks done in dangerous environments (i.e. fire, space,

volcanoes, nuclear facilities, underwater, etc.) Performing tasks that are beyond human capabilities of size, weight, speed,

endurance, etc. Economic improvement: Automation may improve in economy of

enterprises, society or most of humanity. Reduces operation time and work handling time significantly. Frees up workers to take on other roles. Provides higher level jobs in the development, deployment, maintenance and

running of the automated processes.In this project, the further modification points are described below:

1. Make it Motor or Engine driven instead of handle driven:The handle used in this can crusher takes more effort of the worker. For reducing this effort the motor and engine can be used for the crushing operation. The motor’s or engine’s output shaft is connected to the can crusher input shaft with the help of chain wheel gears and V-belt pulley drive. The

Page 44: Can crusher file by Rohit Dhiman

Course work -2|44

motor speed is controlled by the regulators. The motor should be run at a speed that it takes less time for Can crushing and protects the worker from any injury. An Emergency switch is put on the top of the frame to stop the motor immediately. The engine used for this purpose is of small single cylinder

engine. The engine’s output shaft is connects to the can crusher’s input shaft with the help of V- belt pulley drive or with the help of spur and helical gears. The speed of the motor for this purpose is 1000-1500 rpm. The below given figure shows the motor or engine for this type of can crusher:- (a) Motor (b) Engine

2. Use of Bearing instead of Bushes: The bearing and bushes provides mechanical support to the rotating shafts of can crusher. Friction occurs more in bushes as compared to the bearings. Bearing provides smooth and steady operation to can crusher’s shafts while mitigating friction. The ball bearing are suitable for the shafts of can crusher for power transmission. Ball bearings transmits high power with no jerks and frictionless operation. The two views of ball bearings are shown below:-

Course work -2|47

better speed and torque during the run of can crusher and provides better crushing of cans in less time and less effort.

The given figures shows the CAD drawings of flywheel:-

Flywheel

Force volume change:

A force acting on all particles (volume elements) of a given body and proportional to the mass of the particles. A force can change the volume of an object. Some objects are not very compressible. In case of can crushers, if the volume inside the can is higher, then more force is required to crush a can but if the volume inside the can is less, then less force is required to crush a can. The given figure shows the change in volume of Can after applying force:

Page 51: Can crusher file by Rohit Dhiman

Course work -2|51

The can has air pressure exerted on it both from outside and inside and those forces are responsible for the can's subsequent demise.

Newton's second law deals with the sum of the forces. As long as the forces inside and outside are balanced and equal, the can undergoes no change. When the forces are unbalanced, changes in the shape of the metal can and will take place.

As the Can collapses, the volume of the Can decreases. The pressure of a gas is related to the volume of its Can. At some point the diminished volume results in an adequate pressure inside the Can to prevent continued collapse.

Force required to crush a can:In this project (Can crusher)

Mass of the object(m)= 18kg

Distance travel by the piston in the sleeve or cylinder(d)= 12inch or 0.3048m

Time(t)= 4sec

Then,

velocity(V)= distance/time

Velocity(V)= 0.3048/4

V= 0.0762m/sec.

Page 52: Can crusher file by Rohit Dhiman

Course work -2|52

Hence,

acceleration(a)= velocity/time

acceleration(a)=0.0762/4

acceleration(a)= 0.01905m/sec2

we know,

Force(F)=ma {according to newton’s second law}

Therefore,

Force(F)=(18)*(0.01905)

F=0.3429N or (342.9)*10−3N

Hence

Force required to crush a can is 0.3429N or 342.9mN(approx.)

How Steel is better than Wood:

- Steel framing material is significantly stronger than wood. In fact, it has the highest strength-to-weight ratio as compared to wood.

- Steel's strength and resiliency is higher than wood.- Individual members of a wood-frame react differently and in varying

degrees to climactic changes. The wood movement due to climatic changes are expansion, contraction, warping, twisting, etc.

- Steel framing won't burn and add fuel to a fire..- steel framing allows greater flexibility during design, construction and

remodeling.- Steel products are all engineered to strict standards of strength and

consistency.- steel is the most recycled material in the world. More steel is recycled than

paper, aluminum, glass and plastic combined.- The steel is rot proof, termite proof, crack proof, split proof, warp proof, non

toxic and not fuel for fire as in case of wood.

How Cast iron is better than Wood:

- Cast iron is a brittle form of iron which is higher in compression than wood. It has a relatively low melting point, good fluidity, castability, excellent machinability and wear resistance. Cast irons have become an engineering material with a wide range of applications, including pipes, machine and automotive parts.

- Cast iron retains high strength in fires, despite its low melting point. It is usually around 95% iron, with between 2.1-4% carbon and between 1-3% silicon. It does not corrode as easily as steel.

Crushing Rate:Crushing rate may be defined as the number of cans crushed per unit time ‘or’ the rate at which cans are crushed.

In this project,

Time taken to crush a single can= 4sec.

Then,

Number of cans crushed in one hour=3600/4

Number of cans crushed in one hour= 900Cans.

Therefore,

Total can crushed in one hour is 900 with manual operation.

Hence,

The Crushing Rate is 900cans/hr.(approx.)

Engineering Aspects:Engineering aspects consider the ways in which systems engineering can both be used to promote effective responses to the technical aspects of contingency events. Engineering aspects gives information about the appearance, features, ergonomic safe to operator analysis and working principles.

Working Principle: This project is works on the principle of reciprocating engine i.e. the rotary motion of the handle is converted into to and fro motion of the piston but the difference is, the engine converts heat energy into mechanical energy with the help of fuel but in this can crusher human effort gives a to and fro motion to the piston with the help of crank shaft and connecting rod. Crank shaft converts rotary motion into reciprocating motion of the piston with suitable leverage or gear system. The hopper hold the cans. This can crusher reduces the size of can up to 85-90%. There is a ejection space in front of sleeve from which crushed can is ejected by the reciprocating motion of the piston.

Innovation:The process of translating an idea or invention into a good or service that creates value or for which customers will pay.

To be called an innovation, an idea must be replicable at an economical cost and must satisfy a specific need. Innovation involves deliberate application of information, imagination and initiative in deriving greater or different values from resources, and includes all processes by which new ideas are generated and converted into useful products.

In this project, the innovation is done by using motor or engine as a driving member as discussed above ‘further modification.’ If we using a motor as a driving member than speed regulators are used for controlling the speed of the motor. In case of engine a gearbox is used for providing variation in speed and torque. An emergency switch is also needed near the operator to stop the can crusher in case of any accident.

In this can crusher we use helical gears for the purpose of smooth power transmission and noiseless operation.

Observation:

During the market survey, I found that there are various types of can crushers available in the market such as hand operated can crusher, foot operated can crusher,pneumatic, hydraulic and electric can crusher. But out of these can crushers hand operated and foot operated can crusher are mostly used due to there less cost and less effort for operating.

Page 55: Can crusher file by Rohit Dhiman

Course work -2|55

These can crusher smashes the cans from 12oz to 17oz.This market survey enabled me to study the wide range ofcan crushers and compare them on varying factors such as the raw materials used, the functions such as operating principle, specifications and cost. During this survey, I see various design of different type of can crushers. In the market various designs are available they are efficient, soundless and takes less effort of operator or having facility of wall mounting or mounting on table.The market survey helped me in understanding the individual parts and also functioning of the hand and foot operated can crusher to some extent.

Conclusion:

From the observation, I conclude that there are lots of type of Can crusher available in the market. I notice that there are different design. Out of all the Can crushers I take hand operated reciprocating can crusher and make free hand sketch on the piece of paper and analyze the design, and makes its drawing in solid works. After this by using suitable manufacturing process assemble the can crusher. This project provides the knowledge about the manufacturing process and different designs of leverage and power transmission with the use of v- belt drive or gear mechanism. This project is quite successful and able to meet the all requirements.
