My original thought consisted of a V shaped channel, with the bottles standing up right. Pressure would be maintained by a string lasso being wound in by a motor. It would probably work, but even adding that I wasn’t counting the load area, due to its general characteristics, I’m not super happy with the footprint or gestalt.
This brings me to thinking vertical.Have the bottles in a tilted rectangular hopper with the output rotating out and down. It might look dope but I’m pretty sure it’ll be more work. One of my co-workers pointed out the silliness of the project for two score bottles a month at most, but there’s a principle to it. At the end of the loader have two rubber wheels, one on the bottom pulling the bottles in, and the one on the top will push bottles out, kinda like a vacuum feed on a printer.
As long as I have the filling automated, any which way is fine by me.
