Konstruktion och programmering av lerduvekastare
This degree thesis is based on an assignment from BEOMAT in Storfors. BEOMAT is a company that constructs and sellsclay pigeons to both the national and international market.Our main purpose with this paper is to find a solution/system that can replace the expensive and space demandingOlympic trap facility. Our solution will replace fifteen clay pigeon throwers with one automatic thrower whosimulate all throwers together. The system will be provided with an appropriate control system for mass productiontherefore this system needs to be user-friendly so no previous knowledge is required.Totally 405 different throw coordinates will be stored in the programme in nine different subprograms. According tothe Olympic-rules the throwers should coincidence within certain specified conditions, this will be solved with anrandomizer in the programme. The equipment needs to be able resist all outdoor weathers since it is going to beinstalled outside. The software has to be enabling to update so the thrower can be reprogrammed or updated for anyspecific requirements, regulatory reforms etc.In addition, the reader gets an insight into general aims and problems we encountered and resolved during along theway. Thereafter various forms of clay pigeon shooting are presented to give the reader a general picture of how thesport is executed. Finally we describe our actions, the selection of the equipment and also a little about theprogramming of both PLC and display.The PC control system that was assembled on the clay pigeon shooter earlier did not was a good solution with ourrequirements. The old system was replaced with PLC model EC-4P-221-MRAD1 with an external steering display.
