Because of the wear of the sewing needles of embroidery machines defects can appear on the embroidery surface of the product. Therefore, it is necessary to schedule the moments of replacing the sewing needles of the embroidery machines based on the anticipation of their failure moments. Within this framework, the purpose of this study is to develop a fuzzy decision system for determining the moment of replacing of the sewing needles of embroidery machines, considering their amplitude of vibrations measured on the three axes of the Cartezian coordinate system
it is necessary to schedule the moments of replacing the sewing needles of the embroidery machines based on the anticipation of their failure moments. In the past years, through the development of different types of sensors, the scheduling of the replacement of components has been moved from a statistical approach to a condition-based maintenance . Modern diagnostic techniques use sensors that determine the state of the equipment by comparing the signals received from the sensors at a given moment with signals corresponding to their good functioning status .
This study describes some
possibilities of setting up an adaptive control method for an
electromagnetically actuated presser-foot in an industrial high-speed
sewing machine. The control of fabrics feeding in sewing machines is
difficult not only because of the complexity of relations between the
intervening variables (material properties, sewing speed), but also
because in many operations a varying number of material plies are
crossed. This implies that the reference for the controller has to be
adapted dynamically. Several methods, using PID and/or fuzzy logic
control, have been tried and are described in this paper. A preliminary
sewing test is able to provide data to tune the controller variables.
With these adaptation techniques, the machine would be able to
automatically adapt its feeding system according to the material being
sewn.
On the other hand, the wear of sewing needles is a complex process and its estimation is influenced by a certain uncertainty. In such situations, the fuzzy logic can be used to schedule the moments of performing the replacement of the sewing needles actions of textile machines . In this framework, the purpose of the present paper is to develop a fuzzy decision system for determining the moment of replacing of the sewing needles of embroidery machines, considering the amplitude of vibrations of embroidery machines measured on the three axes of the coordinate system OXYZ.
