Tasks Completed:
- Discussed the pros and cons of mounting positions--transmission/chassis or hopper
Pros on Chassis --> (Over CIM motors)
- Better protection
- Less pain!!!
- More secure
Cons on all Chassis
- 3" marker limit - which makes our first design fail.
- Difficult access
- Less clearance and more cramming
- Difficult wiring
- Larger chance of shorts
Pros on Mounting on Hopper
- Lots of space
- Small chance of shorts because of space
Cons for Mounting on Hopper
- Weight concerning large guage wire
- If mounted on lexan, unstable
- If tipped, electronics could get damaged
Height of CRio
- Need 6.5" minimum - 8" maximum Data cable from CRio Digital Side car
Sensors at Top of conveyor and bottom of conveyor
Currently have 1
Banners are functional - Can be used.
To do - Investigate OMRONs (Order from Digikey? 16.81 in onsies) - 11mm sensing distance - Is this good enough?
Detectable distance (See Note.) 11 ¦ 2 mm (Black paper and OHP paper) 11 ¦ 8 mm (White paper)
Non-detectable distance (See Note.) 20 mm (Black sponge) 45 mm (White paper)
Helpful Links to Sensor pages, ect.
Digikey Omron Reflective Sensor
Talked about photoreflective vs. Photo reflective "beam break" sensors
How a reflective Sensor functions
Tasks In Progress:
- Process on choosing mount locations-- Chassis or Hopper
Tasks to Complete:
- Talk to Mechanical 1/2 for status on Chassis, do we still have a 3" limit? WE NEED DIMENSIONS.
- Aquire transmission dimensions
- Hybrid design..? Some on Chassis and some on Hopper?
Images & Additional Updates:
(Use the upload file button on the toolbox to the left to upload the file, then insert an image using the button above. Sizing can be done using the length/width pixel size)
