Bar Manipulator

Hello

I would like to design a bar manipulator whose size is less than 1mm diam and the length varies between 50 and 120mm.
In order to allow the imagination, I will not give information on the solutions already realized or envisaged.
The purpose of this manipulator is to make the bar fit into a spindle and then machine it. The spindle has toolings that long changes to FCT of the bar diam range.

To put material in the charger, a small box the size of a cigarette pack is envisaged. You have to load every minute and it must be as fast as possible to avoid downtime.

We have already encountered problems with bar jamming in the area that supplies the manipulator.

thank you in advance for your ideas :slight_smile:

To help with the jamming and speed issues, you could design a small vibration-assisted feeder that gently moves the bars into place, one at a time. Pair it with a simple escapement or mini gate that lets each bar drop into the manipulator cleanly. Using low-friction materials like PTFE in the guide channels can really help avoid sticking. For the loader, imagine a vertical cartridge (like a cigarette pack) where bars are stacked and gravity helps feed them down smoothly. A small spring-loaded or pneumatic pusher can then transfer each bar into the spindle area quickly and reliably. This setup should make loading faster and reduce jams without overcomplicating the system.
