pieces from these belts. The PLC synchronizes the
two work cycles, thus allowing each pair of robots
to pick alternately the valve body to be processed
from the feeder and to place the pieces already
processed on the same unload belt, thus filling it on
four parallel lines. Such a solution allows users to have
always pieces ready to be picked on the edge of the
belt and to collect at least 36 finished parts in case
of long picking interruptions at the end of the belt. In
case of malfunctioning or maintenance interventions,
it is possible to stop half of the plant on one of the
redundant parts and to enter the area safely. Here
are two optical barriers that separate the two pairs
of robots from the shared area with belt loading/
unloading areas. The two pairs of robots are equipped
with multitasking software and double multi-move
cabinets. The solution with four robots allows for a
machine time of 1.65 min for each pair of robots, then
0.825 min/piece. The guaranteed cycle time is 0.9
min/piece, while the efficiency level reaches 98% on 3
shifts.
The work cycle, in detail
Going into detail on the several process stages, the
operator loads the elements on the feeder and allows
the motor to move towards the machine inner part.
Here, the Robot1 of one of the cells picks the piece
from the belt with the first gripper and places it on the
processing tool for a very first brushing and deburring.
Once this process is completed, the Robot1 goes to
the Robot2 clamping station, picks with its second
gripper the possible piece already processed, places
the piece with the first gripper and then comes back
