Die Cast Robot Tending Automation - Midwest Engineered Systems

The Challenge

Midwest Engineered Systems provided a die-cast robot tending automation machine for a hardware manufacturer.  MWES was asked to provide the customer with a FANUC robot to tend a new Frech Die Cast Machine. The factory automation system was also tasked with loading the cast part into a Trim Press. In addition, MWES had quoted additional automation and services to make a complete automation system. The challenge of this project was to achieve an 18 second part to part cycle time.

The Solution

  • Fanuc Robot – This includes M710iC/50 Fanuc robotic arm with R-30iB Mate Controller, DCS Position & Speed Check, ASCII Program Loader, Soft Float, and PC Interface.
  • Robot Accessories – The equipment includes a robot EOAT with a pneumatic gripper system, cable harness, and robot mounting base
  • Part Verification Stand– This includes a stand and sensor array for part presence after the extraction process has been completed.
  • Dunk Quench System – The equipment includes a welded stainless steel tank, heat exchanger, HP Pump, all necessary controls for the system, all necessary valves, and all necessary piping and filtering.
  • Cooling Conveyor, Scrap Conveyor and Chutes – Integration of conveyors and chutes into the system.
  • Motorized Turntable – Integration of a turntable allowed parts to accumulate. This meant the Die-Cast and Robotic Part Extraction process could continue if the operator were to step away for a few minutes. In addition, the Turntable part accumulator allowed for efficient use of floor space.
  • Safety Features – This includes black mesh safety guarding, safety interlock door access, RAG stack light and emergency stop button. The safety solution supplied met the requirements set forth by ANSI/RIA R15.06-2012.
  • Controls System – electrical enclosure, electrical panel, power transformers for 480VAC – 120VAC, over current protection, contactors, Allen-Bradley CompactLogix PLC w/Ethernet, Allen-Bradley Panelview Plus Compact 1000 machine interface, electrical control interface for all system I/O, conveyor motor starters or drives, wire way, terminal blocks, fusing, and safety system interface.

Impact to the Customer

  • Higher quality results
  • More efficient and quicker part to part cycle time (18 seconds or less) with higher throughput
  • Improved operator safety
  • Improved error recovery
  • Improved equipment maintainability
  • Improved scrap recovery (MWES Scrap Recover System fed scrap directing back to the furnace)
  • Lights out operation improved overall system OEE
  • Improved floor space utilization
