The model Process Cell simulates a process cell with an integrated circular store,
as used for example in industrial metal cutting processes. The process cell consists
of a rail leaded carriage with a conveyor belt, two slewing tables with conveyor
chains, a vertical milling machine and three conveyor belts. The different means
of transport are arranged in a closed circuit. Mechanical switches control the end
positions of the moveable conveying units and inductive proximity switches check
positions of parts. The simulated process shows a part being brought into the circular
store, then being clockwise transported to the vertical milling machine, where it
gets machined, and finally being brought out to a discharge station. The unmachined
part is laid onto the conveyor belt and is brought to the rail leaded carriage.
The carriage brings it to the next conveyor belt. There the part is transported
to the slewing table, which executes a 90°-turn (+C-direction) to bring the part
to the next conveyor belt. This conveyor belt transports it to the milling machine.
The upright housing executes a motion along its –Y-direction to draw near
the part. The spindle starts rotating and gets moved along its –Z-direction
to intimate a machining sequence. After finishing this sequence, the upright housing
and the spindle are brought back to their starting position and the machined part
is conveyed to the second slewing table that brings it back again onto the first
conveyor belt, ready to be withdrawn.
