System for cyclic operation of self-running objects

A system for cyclicly operating a plurality of self-running objects said system comprising:

• a. a first reservation means for receiving empty ones of said self-running objects;
• b. a first working stage including a plurality of first working units for receiving empty self-running objects and for loading said self-running objects with a product produced by said working units;
• c. a second reservation means having a plurality of reservation stations corresponding to said working units for receiving said self-running objects with said products thereon from said first working stage;
• d. a second working stage including a plurality of second working units for receiving said self-running objects with the products thereon, performing a second operation on said products and returning said products to said self-running objects;
• e. central control means;
• and
• f. guide means interconnecting said first reservation means, said first working stage, said second reservation means, and said second working stage for guiding the movement of said self-running objects and for carrying control signal between said central control means and said self-running objects, wherein said guide means comprises a first common guide line extending from said first reservation zone towards said first working stage, a first plurality of guide lines branching from said first common guide line each of said guide lines passing through a first working stage and a second reservation stage, a second common guide line interconnecting said first plurality of guide lines to a second plurality of guide lines each of said second plurality of guide lines passing through one of said second work stages, and a third common guide line coupled between all of said second plurality of guide lines and said first reservation means, wherein said guide means forms a continuous loop for guiding said self-running objects.
