Abstract
In this project I am going to make this fully automatic by using electronics equipment like sensors,
microcontroller, IC’s etc. along with mechanical components due to which crushed cans or bottles are need not
to segregate from bin and also machine will not run idle. After all process has been done, this crusher may
help us to understand the fabrication and designing process as well as electronics equipment that involved in
this project. After the design has complete, it was transformed to its real product where the design is used for
guideline. Crushers are major size reduction equipment used in mechanical and allied industries which crushes
different types of soft and hard materials. The can or bottle crusher machine is widely used in beverage
industries or in scrap dealers shop to reduce the volume of the cans/bottles. Hence in this design and analysis
of various parts are necessary. The Electric Motor and a microcontroller make up the backbone for this project.
Overall, this project involves processes like design, fabrication and assembling procedures. This project is
mainly about generating a new concept of can/bottle crusher that would make easier to bring anywhere and
easier to crush the can or bottle.
Introduction
A can crusher can be defined as “A device used for crushing aluminum cans or plastic bottle for easier storage
in recycling bins thereby giving you extra space by flattening of cans”. This project consists of designing and
fabrication of an automatic can/bottle crusher machine. In order to reduce the waste, we planned to create a can/bottle crusher that will reduce the volume of aluminum cans/plastic bottles by approximately seventy
percent by which transportation volume will increase and transportation cost will reduce. Can crushers are
primarily used to save space and for recycling. Also the purpose of this project is to understand the
fundamental knowledge of design and mechanism by using fulcrum system and a simple mechanism property.
A mechanical can/bottle crusher machine is basically one of the most aid able machines. It helps to reduce the
pollution of the environment. Thus helps to create a better place to live in, apart from that, this can/bottle
crusher can actually be the future mode of recycles apart from the recycle bins. It can be placed everywhere, in
the park, houses, restaurants, malls, canteens even in cars. Using a similar type of a design from the diagram
below, but with an added bin below the can crusher concept of recycling can be applied. In this project,
development of a recycle bin can/bottle crusher so the cans might crush as flat and look as symmetrically as
possible and inserted the bin. The designs are an environment friendly and use simple mechanism properties.
The design is so done that the knowledge of designing, mechanism and forces. The study of manufacturing was
very important in order to carry out this project to ensure that what are needs to do. This project is about
designing and fabricating the Recycle Bin Can/Bottle Crusher Machine to help people easy to crush the can as
well as bottle and bring anywhere. This project involves the process of designing the different parts of this
crusher machine considering forces and ergonomic factor for people to use. After the design has completed, it
was transformed to its real product where the design is used for guideline. This project is mainly about
generating a new concept of can/bottle crusher that would make easier to bring anywhere and easier to crush
the can or bottle. This machine is developed solely for the purpose of recycling as plastic bottles are harmful to
environment and aluminum to plants growth. Many people recycles items like paper, glass, and aluminum,
While these efforts are a vital part of the process, the true recycling path continues long after recyclables are
collected from household bins or community drop-off centers etc. Collecting, processing, manufacturing, and
purchasing recycled products create a closed circle or loop that ensures the value of recycling. Recycling
is a series of activities that includes the collection of used, reused, or unused items that would otherwise be
considered waste, sorting and processing the recyclable products into raw materials, and remanufacturing the
recycled raw materials into new products.
2. Concept
This machine is basically works on the principle of Single Slider Crank Mechanism which is the heart of this
machine and it converts rotary motion into a reciprocating machine to crush the Cans/Plastic bottles. In this,
link 1 is fixed and link 2 which is a crank is rotating about fixed link 1 and converts this rotary motion into the
reciprocating motion of slider (corresponds to the link 4) by means of connecting rod which corresponds to the
link 3. This is the inversion of single slider crank which is obtained by fixing link 1.
Working Principle
In this, as the motor rotates the motor is having a smaller pulley connected to its shaft, the smaller pulley
through the v-belt is connected to secondary pulley (Larger pulley) on another shaft which rotates it. Another
i.e. third pulley (Smaller pulley) is mounted on the same shaft next to the secondary pulley, and is connected to
the fourth pulley (Larger pulley) which is on the main shaft by means of v-belt. This arrangement has been
done solely for the purpose of reduction of speed. Except that there also automation has been done, such as
there I have placed a sensor until and unless sensor senses the obstacle (i.e. a Can/ Plastic bottle) the machine
will not start. After machine gets started the power of electric motor is transmitted to the slider mechanism
through belt and pulley arrangement and rotary motion of crank is converted into the reciprocating motion of
slider thus Cans/Plastic bottles will get crushed. There is a separating bin which is placed beneath a crushing
tray to collect the crushed cans/ Plastic bottles also there is a sensor of metal detector type to store the plastic
bottles and cans separately.
Metal Detector
This metal detector circuit electronic project is based on transistors and will provide an visual indication using
a LED and an acoustic sound that will inform you when a metal is detected. This detector must be powered
from a simple 9 volt battery an it needs some little adjustments. To adjust this circuit you need to power it on
and move it away from any metal object .You must turn RV2 potentiometer fully clockwise and RV2
potentiometer anti-clockwise. With SW1pressed you must turn RV1 anti-clockwise until the LED is about to
light and all further sensitivity adjustments should now be done by turning RV2. To set maximum sensitivity,
turn RV2 until the LED is weakly lit. The brightness of the Led indicates the distance and the size of the metal
object detected .The L1 and L2 coil must be on the same support that must have a 8mm diameter. L1 has 120
turns from 0.3mm Cu wire and L2 has 43 turns from 0.3mm Cu wire.
TSOP Sensor
The TSOP 1738 is a member of IR remote control receiver series. This IR sensor module consists of a PIN
diode and a pre amplifier which are embedded into a single package. The output of TSOP is active low and it
gives +5V in off state. When IR waves, from a source, with a centre frequency of 38 kHz incident on it, its
output goes low. Lights coming from sunlight, fluorescent lamps etc. may cause disturbance to it and result in
undesirable output even when the source is not transmitting IR signals. A band pass filter, an integrator stage
and an automatic gain control are used to suppress such disturbances. TSOP module has an inbuilt control
circuit for amplifying the coded pulses from the IR transmitter. A signal is generated when PIN photodiode
receives the signals. This input signal is received by an automatic gain control (AGC). For a range of inputs,
the output is fed back to AGC in order to adjust the gain to a suitable level.
Conclusion
From the above study, it is observed that by arranging different mechanical components along with electronic
components machine can be made automatic one to crush the Cans as well as plastic bottles solely to reduce
the volume. Thus human efforts can be reduced as well as time also, because sorting system is installed there to
separate the bottles and cans to reduce the human fatigue. As above results shows that the volume can be
reduced to a large extent i.e. near about seventy percent volume can easily be reduced, thus transportation
volume can be increased and transportation cost can be reduced to a large extent and these can be reuse.
