The standard for automation in machine construction today is still the classic PLC. There are many different options for connecting sensors and actuators to the controller. Most requirements are readily met with the 750 I/O-SYSTEM and 767 SPEEDWAY series. This also applies to the field of specialized machine construction, where modular solutions are required.
Specialized machine construction takes place whenever it is not possible to use standard machines, such as CNC machining centers, in production. Machines are created that frequently perform a great variety of production steps, which are then also combined with measurement and testing technology. Typical examples are joining and mounting steps during assembly of complex products – such as outsourced parts for automobile construction. Specialty machines are always designed and built for a particular task. To allow a certain degree of flexibility and repeatability with such machines, despite their specificity, they are frequently subdivided into individual modules – called “cells” – each of which performs one specialized process. A workpiece conveyor system ensures a smooth automatic progression between the individual cells. This also simplifies integration of any required manual work stations into the sequence.
