This application discloses an automation system whereby a number of different machines, test stands, and the like, previously operated as separate machines or installations, are grouped together with the aid of an accumulator conveyor system into a unitary system operating substantially as a single machine, with the operators merely loading and unloading workpieces at a predetermined place or station. The application discloses as a particular example an installation for combining into a single installation a number of test stands and machines directed to testing automobile engines, as well as operations related to such tests, such as filling the engines with oil, balancing the engines, hot-run testing the engines, removing rejected engines from the installation and directing them to repair stands and the like, and dynamometer load testing. The construction utilizes the nonpositive accumulator conveyor such as disclosed in detail in our copending application identified below. In some of its aspects the present invention relates to an improved method of automating industrial plants or portions thereof formerly composed of a large number of independent units, machines or devices, as single systems.
