The sewing work can work in a situation where there is no under-thread by mistake. This leads to defective products and economic losses. To solve this problem, there is a need for a device for detecting the remaining amount of under-thread and transmitting it to an operator. Fig. 3 shows the sensing signal configuration for system design to detect the residual under-thread amount and the system configuration diagram to control it by linking it. The orange block shows the status of the warning lights, the PLC, the touch screen, and the main brake, while the blue block indicates each sensor and control signal for control.

Maintenance Scheduling of the Embroidery Machines Based on Fuzzy Logic Marius Baban Department of Industrial EngineeringUniversity of Oradea Oradea, Romania mbaban@uoradea.ro Calin Florin Baban Department of Industrial EngineeringUniversity of Oradea Oradea, Romania cbaban@uoradea.ro Edit Toth (Kiss) Doctoral School of Engineering SciencesUniversity of Oradea Oradea, Romania keditke85@gmail.com Abstract—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.Keywords— schedule, sewing needles, embroidery machines, fuzzy logic I.INTRODUCTIONThe embroidery machines are complex equipment with a single or multi-heads, which are controlled through PLC. In the case of embroidery machines, the sewing needles largely influence the quality of the manufactured products. Considering the influence of sewing needles on the quality of textile products, the existing works presented in the literature aimed to study the penetration force of the needles in the textile material the influence of the sewing needle temperature on the textile material and the influence of the vibrations of the embroidery machine .

The wear of sewing needles is characterized by the changing of the size and shape of the needle, and the displacement of the needle axis relative to the vertical direction. Due to the wear of sewing needles, at high vibrations during the operation of the embroidery machines, there is wrinkling of the material on which the embroidery pattern is applied and breaking of the sewing thread can occur so that the embroidery machine has to be stopped. It is necessary to reposition the sewing needle with 6-10 stitch steps behind the trajectory to follow and the embroidery machine should be restarted. When the embroidering process restart, an overlap of the sewing thread occurs. Therefore, because of the wear of sewing needles defects appear on the embroidery surface of the product, the availability and thus the productivity of embroidery machines decrease, while the manufacturing costs are rising know more
