This is for packaging and bottling machines.
The main movement of the is in a single direction of rotation.
The linear speed is constant during movement, or varies slowly in relation to the machine rate. The positioning of the outputs is the same for each .
Parts arrive periodically:
-
One part for each cycle. All the parts should enter systematically for the same position angle value in each cycle (mechanical problem).
-
There can be active on several cycles.
-
Certain grouping operations, for example, may be performed in a single cycle (one cycle in 4, for example).
In this type of application, means a usage value. The recipe groups together the data required for the module to control the machine for a series of parts. The recipe can be modified or completely changed by the PLC application.
Two types of can be used, single-turn or multi-turn. The number of turns is not necessarily a power of 2.
Example of a cyclical axis
A cycle is made up of 1024 pulses and corresponds to the distance between two parts. The complete machine cycle is performed over 8 cycles. The start of the cycle (arrival of the part) is offset by 50 pulses in relation to the machine 0.
Reflex operations on parts:
Point 0 of the machine is defined when the tool box and the conveyor are synchronized (indexes facing).
