The Can Crusher Group 12 Stanley Andrews Brandon Jefferson
Motivation
•Wanted to incorporate more electrical design into the idea of the “Can Crusher”
•Use pneumatic cylinders (3 pneumatic cylinders in this project)
•Thought it would be something different from previous senior design projects
Objectives• Step 1: Can or water bottle is placed into the trash can. Can/Water
bottle enters hopper and waits for it to be identified by the optical and reflective sensor.
• Step 2: Rotary cylinder rotates the object and sends it down the ramp. • Step 3: Sorter determines route of the object based on feedback from
the sensors. • Step 4: If object is a water bottle, the pneumatic cylinder will extend,
adjusting the direction of the sorter• Step 5: If the object is an aluminum can, it will be routed towards a
push cylinder and crushed• Step 6: Push cylinder crushes the aluminum cans and sends remains to
the storage bin• Step 7: Process continues until storage sensor alerts operator that
storage bin is 90 %filled.• Step 8: Once storage reaches 90%. Can crusher goes into “Stop”
mode. Items from storage bin, can then be removed.
Features• Fully automatic can crusher and sorter • Detect when an object is placed in the hopper• Be able to distinguish between an aluminum can
and a water bottle • Sort the water bottle into a separate storage bin
from the aluminum cans• Be able to crush the aluminum cans and put into
storage bin • Detect when the storage bins are full • Have three different modes “Standby”,
“Operational”, “Stop”
Hopper
Hopper
• Where the bottle and cans will be placed • Be able hold 16.9 FL oz. water bottle
and 12 - 16 oz. aluminum cans • Two sensors will mount to detect the
object inside the hopper
Sensors
•Parallax Ultrasonic Sensor•Reflective Optical Sensor
Parallax Ultrasonic Sensor
• Part a) is the ideal circumstance you would want to be in. The sensors should be facing the object on a level plane

Reflective Optical Sensor• Get the best results (peak
operating distance) at 2.5 mm
• One of the challenges will be to get it close enough to the object stored in the “hopper”
Aluminum Cans/ Water bottles
Terms of Service
•We ask that all contents are empty •All objects must be placed horizontally in
the hopper•By default system will be in “standby
mode”, once an object is placed inside, the system will go into operational mode
•If storage bin is full no objects can be placed into the system

Design Overview
Sorter• The idea is called the “Swinging lid”
• Uses pneumatic cylinder to be able to “swing” the lid and alter the objects path
• Routes Aluminum Cans to Can Crusher
• Routes Water bottles to storage bin
Motors/ Air CompressorElectric motors Air Compressor
Pros • Uses Standard Outlet • Option to convert AC to DC • Very Compact and small to
maneuver and place anywhereCons• Most motors only have one
speed• No way to speed up or slow
down the project• Very Expenses for high power
motors• Only can
Pros• Uses a Standard Outlet• Able to adjust the air pressure • Ability to control the speed of the
motor by the PSI• Option to convert AC to DC• Not to expensive economy for the
budget• Can use air solenoid valves that can
control of a multiple operated air pressure components
Cons• Tank will have to be refilled when low
on air • Will need multiple air hoses• Very big hard to hide and maneuver • Very loud when filling up the tank
