automation
At the top of the machine is a stack of punched cards that would be fed into the loom to control the weaving pattern. This method of automatically issuing machine instructions was employed by computers well into the 20th century.
Automated production lines move parts through a series of workstations using a specialized transfer system designed to coordinate the movement and positioning of workpieces. These systems ensure that parts are accurately delivered to each station for specific processing or assembly operations.123
Common mechanisms used to facilitate this movement include:
- Conveyor Systems: Various conveyor devices, such as belt conveyors, monorail trolleys, and floor-mounted chain or cable systems, are used to transport materials and workpieces between stations.24
- Transfer Machines: These are landmark systems in automation that move workpieces to the next workstation and precisely position them for the next machine tool.2
- Handling Mechanisms: In pressworking lines, specialized handling mechanisms transfer partially completed parts from one press to the next.1
- Programmable Control: Modern lines utilize programmable logic controllers to manage the timing, sequencing, and coordination of these transfers, ensuring the line operates efficiently with parts being processed simultaneously at each station.1
