Operation and Control System
?
Signals from robot system to the
injection moulding device.
Cl. mould SET
Sets the signal to the IMM – Enable tool (TL)
close. The robot system sets the signal to logic
”1” to indicate to the IMM that the mould can be
closed. It is important that the robot is outside of
the mould halves so as to avoid collisions
occurring. This signal is reset by ”Mould closed”
in the PCS.
Op. mould SET
Sets the signal to the IMM – Enable tool (TL)
close. The mould is opened automatically after
completion of the cooling cycle. This prevents
the casting from cooling down completely and
becoming stuck inside mould. The closing plate
opens until it reaches the ”TL at intermediate
stop” position. The robot enters the machine
and grips the casting. In the case of extremely
deep moulds, e.g. for barrel-shaped vessels, the
machine should be allowed to open the mould
further after gripping it. To do this, the robot
signals to the injection moulding machine that
the mould can be opened further by setting the
”Enable TL open” signal to logic ”1”. The
machine then pulls the long core out of the
barrel-shaped vessel and activates the ”Tool
open” signal when it reaches the end position.
The ”Enable TL open” signal is reset by the ”TL
open” signal in the PCS.
Ej. back SET
Resets the IMM signal – Enable ejector back.
The robot system sets the signal to logic ”1” to
indicate to the IMM that the ejectors can be
retracted. This signal is reset by ”Ejector is
retracted” in the RPS.
Ej. forw. SET
Resets the IMM signal – Enable ejector forward.
The robot system sets the signal to logic ”1” to
indicate to the IMM that the ejectors can be
moved forward. This signal is reset by ”Ejector
is forward” in the RPS.
Cp. rem. SET
Resets the IMM signal – Enable core pullers
removal. The robot system sets the signal to
logic ”1” to indicate to the IMM that the core
pullers can be moved to the removal position.
This signal is reset by ”Core pullers in removal
position” in the RPS.
Cp. in SET
Resets the IMM signal – Enable enter core
pullers. The robot system sets the signal to logic
”1” to indicate to the IMM that the core pullers
can be moved to the feed position. This signal
is reset by ”Feed in ejectors” in the RPS.
