Dual-Station Screwdriving Automation -- 2

I need to cut our current assembly cycle time by at least 60 %, so I’m commissioning a fully-automatic, dual-station screwdriving cell for a line that builds small stamped automotive components. The system must handle machine screws no larger than M3, feeding, positioning and torquing them with zero human intervention once a part is loaded. While one nest is running the drive sequence, the second must sit idle and safe for the operator to unload and reload, guaranteeing continuous flow.

Core expectations
• Clean, jam-free screw-feed mechanism built for small machine screws
• Two independent stations with light-curtain or similar guarding for safe concurrent loading
• Programmable torque and depth control with live feedback and error-flagging
• Cycle-time proof demonstrating the promised 60 % reduction versus our current manual method
• All mechanical drawings, electrical schematics, PLC/HMI code, and a complete BOM ready for procurement and build
• Remote acceptance support plus clear commissioning instructions

I’m flexible on control platforms—Siemens, Allen-Bradley or Omron are welcome provided spare parts are readily available in Europe—but insist on open, non-password-protected code. If you have experience with miniature screw feeders, servo-driven Z-axes and poka-yoke verification for automotive parts, I’d like to review a brief proposal, lead time and any similar projects you have already delivered.
