This is my latest project at work. The project started with a machine that dropped round bottles into a bottle handling container called a puck. With a round bottle, no in-feed screw was needed to run the machine. We quit running the round bottles on Line1, so we moved the machine to Line4. This line is currently running a n oval, 1.7 oz. Old Spice Red Zone Body Wash, and a semi round 2.0 oz. Olay bottle. I had to retrofit a drive unit, from a junked machine, on this machine to feed the bottles into the star wheel. Once the bottle is engaged by the star wheel, they travel 90° then drop off of a plate into a puck. The pucks are fed with their own star wheel & timed to the bottle handling star wheel.
Th plates on which the bottle handling parts were designed by me, using TurboCAD & the bottle handling parts were all designed & manufactured by me, except the in-feed screw, on my 4 X 8 CNC router. here are some pics.
