Example: Packing Piece Goods

Description
Packing is started as soon as a folding box from conveyor 1 is in the correct position. The 24
V control signal controls the pusher and, when the compartmentalized conveyor is in
operation, pushes the piece goods into the folding box. Each pulse corresponds to a
complete movement of the pusher. The next movement of the pusher begins at the next
pulse from the pulse train.
The number of items that have to be packed corresponds to the number of output pulses.
The 2PULSE generates the 24 V control signal on its digital output DO with the number of
pulses you have specified. After the piece goods have been packed, the folding box is
moved on.
Counting begins from the start again when a new folding box passes the initiator.
