Automated Systems
An automated system is differentiated from a semi-automatic assembly fixture in that the operator is not presenting inputs, parts or materials, on every cycle. Instead, components are automatically presented via parts feeders, reel fed indexers or bulk dispensing so that the machine rate is determined by the slowest assembly/test step in the process.
The assembly process itself can be anywhere from a single operation to a series of sequential operations so that on each cycle, each operation is performed on a sequentially built up final assembly and then at some final station, the completed assembly is released.
Stations can include any/all of the operations outlined in the Assembly Fixtures applications listing but can also include test stations, reject stations and other operations which assure that "good" assemblies are produced on a predicable rate.
Machine intelligence is typically controlled via a central Control, PLC or PC Based, along with an HMI which allows the operator to monitor and control any number of parameters. Extensive inputs such as limit switches, safety interlocks, part presence sensors as well as input materials availability sensors, enable the machine to call for parts replenishments as well as assure crash proof machine sequencing. Upstream and Downstream "handshakes" with conveyors or other equipment also enable this type of system to be fully integrated to the total process.
Automated systems are most successful when the input components are well controlled and the process itself is well defined. It's often prudent to prototype and model undefined process steps with a Semi-Automated Fixture prior to full automation.
