For the double multi-position cylinder A-B, we also define that,

while the cylinder C stops by tightening or inserting obstacles in the continuation of the objects’ 

translation, during the time that the routing of each object lasts. The sensors {c, d, e} are placed 

correspondingly in the three conveyor belts {1, 2, 3} for detecting the pass of an object and in order 

to initiate the release from C cylinder of the next one. The individual operational specifications 

are as follows:

  1. When an object reaches the code reading point, the piston C is extended in order to stop the 

translation of the incoming objects.

  2. At the same time as (1), the cylinders A and B are taking the positions corresponding to the 

recognized code.
