Development of a mechatronic thread trimmer

In the production of clothing and footwear, machine tools and semi-automatic machines are widely used. Sewing enterprises and factories of art products are partially equipped with single-needle semi-automatic embroidery machines with microprocessor control modules. Their main equipment is non-automated universal lockstitch sewing machines, chain sewing machines, zigzag stitch machines, in which embroiderers manually move the hoop with the workpiece during the embroidery process. One of the promising areas for improving sewing processes and multi-color embroidery is their automation through the use of mechatronic modules in the equipment used and semi-automatic embroidery machines. On equipment with mechatronic modules, the main operations are performed automatically, which reduces their labor intensity and improves the appearance of products due to higher stitching accuracy. The possibility of simultaneous maintenance of several semi-automatic machines by one operator increases labor productivity. A method for designing a mechatronic module for a thread trimming mechanism is proposed, which is based on calculated and experimental recommendations when designing new semi-automatic embroidery machines or upgrading those used in industrial enterprises.
