Konstruktion och programmering av lerduvekastare

Sammanfattning: This degree thesis is based on an assignment from BEOMAT in Storfors. BEOMAT is a company that constructs and sells clay 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 demanding Olympic trap facility. Our solution will replace fifteen clay pigeon throwers with one automatic thrower who simulate all throwers together. The system will be provided with an appropriate control system for mass production therefore 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 to the Olympic-rules the throwers should coincidence within certain specified conditions, this will be solved with an randomizer in the programme. The equipment needs to be able resist all outdoor weathers since it is going to be installed outside. The software has to be enabling to update so the thrower can be reprogrammed or updated for any specific requirements, regulatory reforms etc. In addition, the reader gets an insight into general aims and problems we encountered and resolved during along the way. Thereafter various forms of clay pigeon shooting are presented to give the reader a general picture of how the sport is executed. Finally we describe our actions, the selection of the equipment and also a little about the programming 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 our requirements. The old system was replaced with PLC model EC-4P-221-MRAD1 with an external steering display.
