Industry application

First, the industry profile

    The electronic pattern machine is a highly intelligent automatic sewing unit, which is mainly used for processing complex shapes of patterns or blanks on bags, shoes and hats. The process of processing these complex patterns is difficult or impossible to accomplish with a manual or ordinary sewing machine. The emergence of the electronic pattern machine has fundamentally solved this problem. The electronic pattern machine generally adopts the thread take-up, stab and hook line mechanism of the sewing machine head (controllable on the upper shaft), plus the controllable X and Y feeding mechanism, and the complicated graphic input required by the programming function of the human-machine dialogue Automatically complete the automatic sewing of a pattern after the sewing material is clamped once. The use of efficient automated production equipment to reduce the dependence of enterprises on labor has become the development trend of traditional manufacturing industries such as clothing, luggage, shoes and hats. It is also driven by this situation that in recent years, the demand for electronic pattern machines has risen rapidly and the prospects are broad. Today, more and more domestic companies are investing in R&D and production of electronic pattern machines.

    Although the current domestic electronic pattern machine has considerable gaps in performance and quality stability compared with foreign brands, with the obvious cost performance advantage and thoughtful after-sales service, the market share of domestic electronic pattern machines is rapidly increasing.

Second, the application of Begerda servo on the electronic pattern machine

    The electrical control part of the electronic pattern machine is mainly composed of the main control box of the pattern machine, the man-machine interface, the X/Y stepping drive, and the direct drive motor (AC, DC servo motor). At the request of a flower pattern machine manufacturer in Guangdong, Beigeda electrical engineer helped the installation and commissioning to replace its original Japanese products. In response to customer requirements and in-depth analysis of the working principle of the electronic pattern machine, we chose our customers for our customers. SD series high speed small inertia servo system: SDB08NK8+80SM-M0230MAL

    First, the wiring is correctly wired according to the electronic control wiring diagram provided by the manufacturer, and then input relevant control parameters, such as control mode, command pulse input mode, electronic gear ratio numerator/denominator, output electronic gear ratio numerator/denominator, motor rotation direction. Power-on, the motor is not correct, the speed is even, the parking is not in place, the sound is soft; through the full communication with the company's electrical engineers, it is known that most of the domestic electronic pattern machine manufacturers use Japanese and Korean AC servo systems. The AC servo has not yet set a precedent for mature application on the electronic pattern machine, which has inspired the enthusiasm of Bergerda engineers. Finally, after analyzing the real-time data, the corresponding position proportional gain, position feedforward, speed proportional gain, and speed integral time are adjusted. After repeated tests such as constants, the final customer was very satisfied with our debugging results, and we placed multiple orders on the spot.

    At present, the customer's application is in good condition, and the order has been continuous. At the same time, we have also cooperated deeply with other brands of pattern manufacturers to form a good reputation in the whole industry.

Third, summary

By using the Bergerda servo system, the production efficiency and process level of the luggage, shoe and hat manufacturers are greatly improved. At the same time, it has greatly improved the comprehensive cost performance of domestic electronic pattern machines, further shortened the gap with imported brand pattern manufacturers, and expanded the share of domestic pattern machines in the market competition.
