The robot-injection molding machine interface is designed according to the directives of
Euromap67, which states:
Unless otherwise noted, the signals, which are maintained during the described function.
2.6.1.1 The Injection Molding Machine Output Signals
Contact No.
Function
ZA1
ZC1
Emergency stop channel 1
The emergency stop switch of the injection molding machine is used to interrupt
the emergency stop circuit of the robot.
ZA2
ZC2
Emergency stop channel 2
The emergency stop switch of the injection molding machine is used to interrupt the
emergency stop circuit of the robot.
ZA3
ZC3
Safety system active channel 1
For protecting against hazardous motions of the robot. The switch is closed when the safety
system of the injection molding machine is active.
ZA4
ZC4
Safety system active channel 2
For protecting against hazardous motions of the robot. The switch is closed when the safety
system of the injection molding machine is active.
ZA5
Optional
Reject
The signal is HIGH when the molded piece is a reject. The switch is closed when the tool is
open and must remain HIGH at least until
“
close tool enabled
”
(see pin contact No.A6).
ZA6
Mold closed
HIGH signal when tool closing has been completed, the signal
“
close tool enabled
”
is no
longer necessary (see pin contact No.A6).
ZA7
Mold open
HIGH signal if the mold opening position is equal or more than the required position.
Inadvertent alteration to mold opening stroke smaller than that required for the robot to
approach must be impossible.
ZA8
Optional
Mold at intermediate position
HIGH signal when the mold opening has reached the specified intermediate position and
remains HIGH until the mold is completely open. the signal may be used in two ways:
1) The mold stops in the intermediate position, whereupon a signal is sent to the robot.
Complete opening of the IMM takes place through the signal
“
complete mold opening
enabled
”
(see pin A7).
2) The IMM transmits the signal, but does not remain in the intermediate position.
Signal is LOW when the intermediate.
ZA9
Signal voltage robot 24V DC
ZB2
Fully automatic mode injection molding machine
HIGH signal, when operating the injection molding machine tighter with the robot is possible.
ZB3
Ejector back position
HIGH signal when the ejector is back, regardless of the position of the movable tool plate.
