Way back in the mid-90s I worked a couple summers at a factory and one of the jobs there was using a machine like this. Now things may have changed in the 30 years since then but it basically just vibrated to get the screws to go down the V. Sometimes one would get through misaligned and you just threw it back in the hopper. Sometimes it would get jammed and you had to spend a couple minutes unclogging it. The screwdriver just had a trigger on it to make it spin. The bit was magnetized so if you got it close to lined up with the screw then it would put the screw in the slot correctly.
