Ranges of application of sorting manipulators

Piątkowski T., Szempruch J.

Vol. 6, no 3

235-244

In the paper the applications ranges of sorting manipulators of unit loads (cubiform objects – e.g. postal packages) transported on conveyors in the continuous manner are presented. The exploitation properties of manipulators have been assigned on the basis of numeric optimization of the sorting process. Theoretical models (indispensable for optimization) include the development of physical phenomena occurring while interaction between the object and manipulator actuators. The reaction forces of impact character appearing between the object and the working element of manipulator are defined by means of modified non-linear Kelvin model. The frictional proprieties of the object are modelled by the non-linear friction coefficient using B-spline curve of third degree. The kinematic structures of the manipulators (taken into consideration during research) are representative technical solutions of currently applied methods of impulse exertion directing the objects on the new transports lines in the logistic centres.
