8 years ago Input conveyor to pull coins up from hopper area: All new laser cut design. A conveyor on an angle to allow the doubled coins to slide off Only 19.2mm wide to stop larger coins from traveling up the conveyor. Not a multi coin sorter. Larger coins can just be picked off by hand.

8 years ago I’m really happy with the first laser cut direct drive (non-gear) conveyor build. Very low cost, easy to build, powerful, and quiet. It’s like $2-4 for parts!
Time redesign the conveyor again: Cut shaft on last builds. Start saving the conveyors on wall. Design for the new 3/16 spacers Go back to a 30mm belt thin frosted. Make the more bearing hole for the 280 motors. Make it easier to put the belt on. The top has to be acrylic because of the 2mm, and the coins could be backlighted. Drill out the bore holes as they are not square and tapered Push motor plate in so there is more drop off clearance Round some corners Cut the middle side rail mirrored so the two counteract each other, also cut it so the clean side faces out.
Changes To Add Solenoid: Top Plate has to be notched for the solenoid rod. Draw the solenoid. Solenoid plate is 6mm screwed into the side rail. Mount it so it wants to angle up. 15mm hole spacing 7mm from end Mounting plate needs to be around 7.5mm lower than conveyor.

8 years ago That worked awesome. Not sure there is much a different between the input and spacing coveyor. I need to build the others first and work back to this one.

8 years ago This is done. It needs to be used in the system and documented
The conveyors work great for in house testing. This is about getting them into people’s hands for testing. All new laser cut, 3D printed, or sourced parts
They need to be easy to make and work with a single frame setup.
Put bearings in them? They are really cheap and might allow for lower cost motors, but I am not sure about this. I really just want to test the system out in the wild before making too many improvements.
Test running on the 1/4” shaft coming off the motor with just tape for a pulley.
I bet I could make an all laser conveyor and zip tie, or even glue the bearings in. I can see 1/8 or ¼ wood pinned.
The gears motors are highest cost part in the system. They conveyors could be designed with DC motors and run straight with no gear reduction, or have an even smaller motor with a single belt reduction. I don’t think this is worth doing at this point.
This issue is really the same as The hopper Issue.
