Part Delivery System in Automated Industry | Automated Assembly | ENGINEERING STUDY MATERIALS Parts Delivery at Workstations Typical parts delivery system at a workstation consists of the following hardware components: 1. Hopper - container for parts 2. Parts feeder - removes parts from hopper 3. Selector and/or orientor - to assure part is in proper orientation for assembly at workhead 4. Feed track - moves parts to assembly workhead 5. Escapement and placement device - removes parts from feed track and places them at station Automated Assembly Systems 18. Parts Delivery System at Station Automated Assembly Systems 19. Vibratory Bowl Feeder Most versatile of hopper feeders for small parts Consists of bowl and helical track ◦ Parts are poured into bowl ◦ Helical track moves part from bottom of bowl to outlet Vibration applied by electromagnetic base Oscillation of bowl is constrained so that parts climb upward along helical track Automated Assembly Systems 20. Vibratory Bowl Feeder Automated Assembly Systems 21. Selector and/or Orientor Purpose to establish the proper orientation of the components for the assembly workhead Selector ◦ Acts as a filter ◦ Only parts in proper orientation are allowed to pass through to feed track Orientor ◦ Allows properly oriented parts to pass ◦ Reorients parts that are not properly oriented Automated Assembly Systems 22. Parts Selection and Orientation (a) Selector (b) Orientor Automated Assembly Systems 23. Feed Track Moves parts from hopper to assembly workhead Categories: 1. Gravity - hopper and feeder are located at higher elevation than workhead 2. Powered - uses air or vibration to move parts toward workhead Automated Assembly Systems 24. Escapement and Placement Devices Escapement device ◦ Removes parts from feed track at time intervals that are consistent with the cycle time of the assembly workhead Placement device ◦ Physically places the parts in the correct location at the assembly workstation Escapement and placement devices are sometimes the same device, sometimes different devices Automated Assembly Systems 25. Escapement and Placement Devices (a) Horizontal and (b) vertical devices for placement of parts onto dial- indexing table Automated Assembly Systems 26. Escapement and Placement Devices Escapement of rivet-shaped parts actuated by work carriers Automated Assembly Systems Escapement and Placement Devices Two types of pick-and-place mechanisms for transferring base parts from feeders to work carriers Automated Assembly Systems assembly system performance is limited by the parts delivery system rather than the assembly process technology Component quality has an important effect on system performance - poor quality means Jams at stations that stop the entire assembly system Assembly of defective components in the product Automated Assembly Systems Quantitative Analysis of Assembly Systems 29. As the number of stations increases, uptime efficiency and production rate are adversely affected due to parts quality and station reliability effects The cycle time of a multi-station assembly system is determined by its slowest station By comparison with a multi-station assembly system, a single-station assembly cell with the same number of assembly tasks has a lower production rate but a higher uptime efficiency Automated Assembly Systems Quantitative Analysis of Assembly Systems Tags: part delivery system in automated industry,delivery part,material handling,automation jobs,automation (industry),automation,robotics,robot,material handling in hindi,material handling equipment,material handling system,material handling safety video,material handling and plant layout,part delivery system,hopper,part feeding devices,part feeder,part feeder mechanism,part feeding systems,part feeding,escapement and placement devices,work part transfer mechanismpart delivery system in automated industry,delivery part,material handling,automation jobs,automation (industry),automation,robotics,robot,material handling in hindi,material handling equipment,material handling system,material handling safety video,material handling and plant layout,part delivery system,hopper,part feeding devices,part feeder,part feeder mechanism,part feeding systems,part feeding,escapement and placement devices,work part transfer mechanism #Engineering_Study_Materials
