After separation of workpieces (cube halves) from
the Magazine Units to the Belt Conveyor their material properties and orientation
are determined. Subsequently workpieces can be sorted onto three slides or moved
forward to the end of the Belt Conveyor. There the cube halves are picked up by
a Handling Unit and moved to the Pneumatic Press. In the Press Unit bothe cube halves
are joined together. Subsequently the Handling unit again fetches the manufactured
cube and forwards it to the ASRS where the cube is stored by the rack feeder.
system uses workpieces made of aluminium, white and black plastic and spring pins
for joining the cube halves.
The mechatronic system consists of 3 base plates
(T-slotted AL-profile plates) which are equipped with the following mechatronic
2 Pneumatic Service Units, 2 Magazine Units, Belt Conveyor,
Sorting Unit (for material testing and sorting), Handling Unit with vacuum suction,
Pneumatic Press, ASRS with rack feeder. The mechatronic system is controlled by
two SIMATIC S7-314C-2PN/DP programmable logic controllers (PLC) and two SIMATIC
TP700 Comfort HMI color touch panels. Both PLCs are connected via ProfiNet. The
ProfiBus interface on board the PLCs may be alternatively used to teach and evaluate
ProfiBus communication instead ProfiNet.
With little effort the system can
be separated mechanically and electrically in two segments. Both controls work independantly
and each control takes care only of the connected system part.

The mechatronic system is provided fully assembled, programmed, tested and ready
