Synchronism between product and
sealing unit.
A 1:1 synchronism between sealing
unit and the product is achieved via
the straight line with the slope 1 in
the cam disc. During the motion,
the sealing unit remains above the
same position on the product.
Fast prepositioning of the sealing
unit to the basic position.
Standstill of the sealing unit in basic
position (modulo: 110 ~ 0).
8.2.5 Cams (TO_OutputCam)
Precise position control of an output, for example, a valve, can be carried out via
the cam technology object. Thus, an accurately positioned product job can be
achieved on the tool via the nozzle.
In example application introduced here, the cam is assigned to the positioning axis
technology object, i.e. the conveyor belt. This makes precisely positioned
processing of the tool possible.
8.3 Programming of the processing stations
In the following chapters the function blocks of the individual processing stations
are displayed in code sections and the programming realized there is explained in
more detail. The blocks are already included in the example application.
8.3.1 Joint data management
Basis of the program concept implemented in this example application is the joint
data management of the application. All units access the data of this example
application. The data, i.e. the positions of the individual products on the conveyor
belt are saved with additional management information in the form of a table in the
"ProductPositionTable” data block.
The "ProductPositionTable” data block has the following configuration:
