Jck57's Full Auto Scanner Scheme #6

Built a scanner? Started to build a scanner? Record your progress here. Doesn't need to be a whole scanner - triggers and other parts are fine. Commercial scanners are fine too.

I've made this alternative circuitry of your idea. If it is not correct or changes are made, I can exchange the image.

Awesome work, dmoura. This drawing will make wiring it up much easier. Relay pin schematic:

Nice work with the revision, dmoura. :D I have all the components here. I just need to make the cams that trip the microswitches.

Hooked up motor relays without any microswitches. For testing I used push buttons to turn the relays on and off.

I think the mechanical complexity should be reduced by adding a separate actuator to raise and lower the whole thing. One gearmotor rotates the part that has both the wedge and flipper. As the wedge comes into position over the book the gearmotor stops and the other actuator lowers the wedge to the book.

A way to separate the rotating from the wedge raising and lowering operations. The bottom driven gear is attached to the axial cam that raises and lowers the whole assembly. The top driven gear rotates the wedge assembly. Of course the problem is making gears. Is there an easier way to accomplish the same thing?

Been looking for a cheap and easy way to convert servo rotary to linear motion. Saw this linkage on a lathe. Thinking of a small drawer slide and a hardware hinge.

Model for intermittent gear drive. By adding separate wheels, I can modify spur gears by simply removing some cogs. One input set can drive two alternating output sets by mounting the output shafts on opposite sides.
