Figure 3.6.7 Function of initial position adjusting
Empty pack skip function
ASDA-A2 uses the feature of motion command overlap. With the assistance of the controller, it
can skip the empty pack. The inertia produced by mechanism when stops instantaneously
should be considered. Thus, when in high speed or heavy load, this function is not suitable for
operation. See Figure 3.6.8. This function can deal with the problem of one empty pack or more
than one empty pack. The prerequisite is to properly arrange the photoelectric switch of empty
pack sensor 1 and 2. When the flying shear is at 0 degree or a proper position (the reference
point for detection), empty pack sensor 1 might detect if there is any package on chain conveyor.
If it is in situation 1, it means no empty pack. One empty pack is shown in situation 2. If there is
more than one empty pack, then it is in situation 3. Thus, the condition of detecting empty pack
should be:
No empty pack: (Signal of E-cam is at 0 degree) AND (Empty pack detection 1)
One empty pack: (Signal E-cam is at 0 degree) AND (NOT Empty pack detection1)
More than one empty pack: ((Situation 2 ) OR (Situation 3)) AND (Empty pack detection1) AND
(NOT Empty pack detection2)
