Robotic Work Cell Implementation

INSTRUCTIONS:

A company that manufactures kitchen products wants to add a set of plastic bowls to the product line. The set would have four bowls with diameters of 6, 8, 10, and 12 inches with a max weight of 5 lbs. Develop an implementation plan and design a robotic cell layout that would include a robot to unload finished bowls from a plastic injection machine , trim excess mold material from the bowls using a trim press, present the bowls to a vision system for quality/defects inspection and place the finished bowls on an exit conveyor and the rejected parts into a reject bin. A single mold die is used for all four bowls. The systems will be a fully automated system. 1. Document all assumptions made ( cell layout, cycle times, mixed products/batch production , etc) 2. Select the robotic arm from fanuc.com and indicate which robot selection criteria were used in the selection process. 3. List vendor names, models, and description for all machines 4. Draw a top view of the cell illustrating the footprint of all machines and the work envelope of the robot. 5. Develop a list of sensors to support the production cell design . Include the model number and type, work cell condition to be sensed. 6. Select the most appropriate end-effector/ gripper for the application and justify the selection. The tooling should be capable of handling the 6- and 8-inch bowls two at the time. Include all calculations associated with the sizing , weight and lifting power. Document all assumptions and vendor selection. 7 . Specify the work-cell control architecture and integration of the robot controller with the other cell control devices like PLC, sensors, machine vision, HMIs, safety systems, etc. 8. Develop a chart showing the operational sequence including the tasks graph illustrating the program flow : all translation point data ( programmed locations), the motion variables ( gripper conditions/state, delays , speed) use at every point and the logic used to make decisions during the program execution. 9. Develop a safety strategy for the cell : risk assessment, hazard reduction, hardware selection ( gates/interlock devices, light curtains, safety mats etc. ) 10. Draw a high-level graphical user interface for controlling and operating the cell 11. Develop a list of all possible faults and alarm events that would require human intervention and the actions required to mitigate these errors ( faulty sensor, translation point is off a few mm, conveyor not running, etc ) 12. Analyze the quality requirements for the bowl production and identify how the vision system can be used for inspection. 13. Identify and present the befits of automating vs manual operation of the cell ( financial/ROI , quality, safety, etc) References : Use the course material and textbooks, https://www.robotics.org, robot vendors websites ( Fanuc, robotiq, abb, denso, universal robots, etc) .
