Operation and Control System

Signals from injection moulding
machine to robot system
Start H if 1 (wait 1) L1
Wait for the signal from the IMM ”Mould open”,
”Activate Start Handling” if the signal is ”0” or ”1”.
The system then jumps to a label. The IMM
signals to the robot system that the mould is
fully open by setting the signal to logic ”1”. In
many removal procedures the robot cannot
enter the IMM until this signal has been given.
Close mould if 1 (wait 1) L1
Wait for the ”Mould closed” signal from the IMM.
If the signal is ”0” or ”1” the system then jumps
to a label.
The IMM signals to the robot system that the
mould is fully closed by setting the signal to logic
”1”. In many removal procedures the
combination of the ”Tool open – Start handling
procedure” and ”Tool closed” signals provides
an additional safety feature to prevent the robot
from colliding with the mould.
Ej.forw. if1 (wait1) L1
Wait for the ”Ejectors forward” signal from the
IMM. If the signal is ”0” or ”1” the system then
jumps to a label. The IMM signals to the robot
system that the ejectors are fully extended by
setting the signal to logic ”1”. This signal is
frequently used so that the casting is not gripped
until the ejectors have moved it to the furthest
forward position. is The sprue grippers, for
example, cannot grip the sprue until the casting
has been correctly positioned by the ejectors.
Ej.bk. if1 (wait 1) L1
Wait for the ”Ejectors retracted” signal from the
IMM. If the signal is ”0” or ”1” the system then
jumps to a label. The IMM signals to the robot
system that the ejectors are fully retracted by
setting the signal to logic ”1”. This signal is
frequently used to prevent the robot from being
raised out of the tool area before the ejectors
have been withdrawn from the casting.
Autom. if1 (wait 1) L1
Wait for the ”Machine in Automatic mode” signal
from the IMM. If the signal is ”0” or ”1”, the
system then jumps to a label.
The IMM signals to the robot system that it is in
”Fully Automatic” mode by setting the signal to
logic ”1”. In the token program this signal is
used, for example, to prevent the robot from
moving between the two mould halves before
the machine is operating in ”Fully Automatic”
mode.
