Another two sensors are for cutting skip and empty pack skip:
ļ The signal of cutting skip sensor only needs to be sent back to cutter axis. And the signal
can enter via any DI. The DI needs to be set to trigger PR and enable macro instruction via
PR writing function so as to prevent the missing cutting.
ļ The signal of empty pack skip sensor needs to be sent back to the master first. Usually, the
detection of preventing empty pack will be conducted in previous packs. The sensor is
normally installed in some distance from the packing materials. When the sensor detects
the empty pack, the master has to be in charge of calculating the package difference
between sealing and cutter axis. When the empty pack is in sealing and cutter axis, the PR
procedure of empty pack skip of two slaves will be triggered. Signals can enter into the
drive via any DI. However, the DI has to be the one which can trigger PR. This DI needs to
trigger macro to stop film feeding axis and cutter axis when the empty pack reaches the
position. Until the next package enters the operation zone, two slaves start to operate.
Thus, it can save the packaging materials. The empty pack skip function of Delta Servo
System can apply to single or multiple packs. However, when applying this function, the
capability of the machine should be taken into consideration. The operational speed for
some machines does not suitable for this operation. For example, if the machine runs at the
speed of 3000 rpm and the package is only 4 centimeters long. Users need to consider
whether it is feasible.
