In the article a construction of robotic stand for cutting the groove in head of cylindrical screw was presented. A technological post is composed of selected module of the robot type PR-02, vibratory feeder and milling unit for groove cutting. The existing control system was modernized by application the OPLC controller. The necessary construction changes were described and the control algorithm was proposed which can be also used for an assembly operation. In a summary the advantages of using the modern control system as well its influence on operational reliability and flexibility of programming maintenance were highlighted.

Artykuł prezentuje metodę tworzenia i sterowania wirtualnymi trójwymiarowymi modelami (3D) stanowisk wytwarzania z wykorzystaniem sterowników PLC. Przedstawiono możliwości budowy modelu wirtualnego przez zaprojektowanie elementów 3D, nadawanie więzów ruchowych, wprowadzanie wewnętrznej logiki działania pojedynczych urządzeń jak i rozbudowanych stanowisk wytwarzania w aplikacji CATIA/DELMIA. Następnie przedstawiono procedurę sterowania modelem w czasie rzeczywistym za pomocą zewnętrznego sterownika PLC GE Fanuc RX3i. Ideę sterowania oparto o wykorzystanie typowych protokołów komunikacyjnych stosowanych w sterownikach PLC oraz serwera OPC KEPServerEX, jako elementu pośredniczącego. Działanie procedury sterowania przetestowano na zbudowanym modelu 3D gniazda obróbkowego wyposażonego w tokarkę CNC, manipulator portalowy oraz zmieniacz palet i magazyn regałowy. Eksperymenty praktyczne potwierdziły efektywność proponowanej metody.

The paper presents a method to create and control virtual three-dimensional models (3D) of manufacturing systems with the use of PLCs. The possibilities of building a virtual model by using of 3D elements, introducing motion transmission constraints and the internal logic of individual devices or more complicated manufacturing systems in the CATIA/DELMIA application are presented. Then the procedure of the real time control of the virtual model using the external GE Fanuc RX3i programmable logic controller is introduced. The idea of control is based on the use of standard PLC communication protocols and the OPC server (KEPServerEX) as an interface application. The control procedure was tested on a 3D model of manufacturing cell equipped with a CNC lathe machine, gantry manipulator, pallet changer and a pallet rack storage system. Practical experiments confirmed the efficiency of the developed method.

Purpose: The aim of this work was to design and build a laboratory stand dedicated for didactic and research purposes connected with a Fluidic Muscle. The stand is placed at the Electropneumatic and PLC controllers Laboratory [10,11,12] of the Institute of Engineering Processes Automation and Integrated Manufacturing Systems of the Faculty of Mechanical Engineering of the Silesian University of Technology, Gliwice, Poland. Design/methodology/approach: The stand was designed and visualised by utilisation of professional CAD software - CATIA and a fluidic muscle was chosen according to a MuscleSIM programme of FESTO company. Findings: The device integrates the elements which are indispensable determinant of contemporary industry and the main aim of its construction was to bring closer conceptions and ideas connected with the construction and the outworking of the fluidic muscle, problems of proportional pressure control, visualisation and control of the industrial processes as well as making possible of carrying out the investigations and experiments on these elements. Research limitations/implications: The module structure of the research stand gives possibility to make its further development by adding extra modules that can be easily mounted on plates, which will make possible the implementation of series of individual positions controlled by one PLC. Thanks to the applied system of visualisation, switching among synoptic screens is possible. The visualisation represents every separate module of the stand and so, with the help of one operator position, gives possibility to control every chosen module of the whole device. Originality/value: The mechatronic didactic and research device introduced in the paper represents the new approach to the problem of visualisation and control of the fluidic muscle and constitutes the perfect tool of the aided didactic process in the Institute's laboratory.
