Seems that the backguage would be pretty simple, you would need an extension table to hold up the guide rods or rails and the cast iron backguage. You'll need a hefty center acme screw or ballscrew....probably 11/2 inch diameter. I would also consider some sort of dashpot arrangement to soften the blow to the backguage from an agressive feeder. Simplistically you could use an input screen where you entered the backguage settings either via a keyboard, a decade switch arrangement, etc. This could all be driven by a single board computer (PIC or ??).
You didn't mention any tolerange or range of setting? |
