Cartesian manipulators are used in textile applications, instead of robots, when manipulations of yarn bobbins or fabric rolls are required, limited to uses associated with less movement in the space or when large radius of action are required in the plan. Also in these cases the insertion of Cartesian manipulators in textile plants allows to replace man in repetitive and alienating activities and in complex and demanding jobs.
With great precision, speed and robustness, in most cases they are associated with suitably sized portal structures to serve the required work area and are they equipped with customized gripping devices.
The use of manipulator is therefore recommended when:
the semi-finished product to be handled must be taken from certain positions which are identified by means of fixed work coordinates
the movements to be performed in the same station are not excessive and require limited movement in the space (associated with 3 degrees of freedom)
the semi-finished product to be handled is particularly heavy and large radius of action are required
the semi-finished products to be handled are palletized or must be depalletized
high flexibility is not required from the system in which they are inserted
