 embroidery machine - vssewingmachine

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.

The 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 [1,2], the influence of the sewing needle temperature on the textile material [3, 4] and the influence of the vibrations of the embroidery machine [5]. 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
 

 
 
Acomputerised embroidery machine, the Memory Craft 200 E is ideal for embroidering up to 140 X 140 mm designs. Multiple font sizes are available for each font to design monograms and a USB Port helps import customized designs. Along with this the free Digitizer Jr V5 software allows one to edit existing designs and making select custom designs. 73 built in designs and a backlit LCD screen help scale up one’s creativity.  View More
