Modeling of Electromechanical Needle Gripping System
Original language description
This paper deals with the modelling of an electromechanical needle gripping system using an electromagnet. The system will be part of a special sew-ing machine for creating a decorative stitch. To sew this type of stitch, a special floating needle is used, which two mechanical systems of needle bars pass through the sewn material in such a way that a perfect imitation of a hand stitch is created. The proposed electromagnetic control of the needle gripping is intended to replace the existing mechanical system, which generates high levels of vibra-tion and noise. This largely contributes to the total noise level of the sewing ma-chine, which needs to be reduced. In this work, a mathematical model of the nee-dle bar is proposed for the Matlab Simulink environment. The model describes the mechanical parts of the needle bar and the links between them, the kinematic excitation of the needle bar, the electromagnet that is used to control the grip and release of the needle in the needle bar, and the electrical circuit that supplies the electromagnet.
