Analysis Of How The Winding Machine Achieves Precise Parking

Analysis of how the Winding Machine achieves precise parking
We usually use the Winding Machine generally have a numerical control system control equipment running state, lap preset, step control, speed adjustment, accurate parking are the basic common function, in which the precise parking function is very important in the winding process One of the functions, it can make the spindle to achieve precise positioning in the process of winding the taps, shop insulation paper and other ancillary processes are needed with this function, then the modern Winding Machine is how to achieve accurate parking?
       The method of realizing the precise stopping of the Winding Machine spindle has the following two realization principles:
       1, the spindle system to install the brake, the common types of brakes are electromagnetic, pneumatic, friction and other categories, including electromagnetic brake is the most widely used, it has a large braking torque, fast response time, easy installation And other characteristics, by the controller system control signal occurs, the brake signal to lock the spindle, to achieve accurate parking.
       2, the use of spindle inertia pre-control and inverter DC braking to achieve accurate spindle spindle, the realization of the principle of the need to control the system spindle inertia pre-control, the spindle power cut off in advance, the use of inertia coupled with the inverter DC brake Spindle to achieve accurate parking.
 Winding Machine widely used with electricity, mining machinery, furniture processing and other industries, for the general equipment. Through the on-line machine production site calls, most of the current use of the JG series ring Winding Machine there is a large security risk, once the improper operation, not only the winding void, and may cause serious damage to the human finger. In order to reduce the rejection rate of the windings wing to increase safety, add Winding Machine protection device is very necessary.
        Recently there is a phase for the JG series ring Winding Machine security risks developed a Winding Machine protection system to be successful. This protective device according to the operator's hand's general position, the degree of danger, the Winding Machine for intelligent deceleration, has reached the purpose of security protection. Winding Machine safety protection device with intelligent, low cost, small size. Control more accurate, etc., have a very good economic benefits and the development prospects of fire.
   Winding Machine intelligent protection device design requirements of the system: ① improve the quality of the winding to reduce the safety accident; ② the entire control system is simple, low cost, small size; ③ according to ergonomic requirements to install the system.
      Through the investigation and analysis, the project identified by modifying the foot governor, in order to reduce the Winding Machine speed, improve the safety of Winding Machine. The operating principle of the pedal governor As with the sliding rheostat working principle, the governor is to change the resistance value of the external control circuit of the Winding Machine inverter, and then change the voltage of the voltage across the control circuit of the Winding Machine. Change the winding inverter output circuit frequency size, to change the Winding Machine click speed. Therefore, to determine the pedal speed control loop, the installation of Winding Machine protection system, according to different degrees of risk fleeing different resistance to change the speed of the Winding Machine motor, that is, the loop line speed.
      When the operator's hand enters the hazardous area, the infrared light emitted by the reflector is reflected in the receiver, the infrared sensor feeds the low signal to the logic chip, and then the logic control chip is based on the Input signal position, through the microcontroller or logic to determine the control signal output to the relay down module, so that different resistance of the resistor string into the foot speed control circuit, and then change the voltage ratio of the pedal device, thereby reducing the Winding Machine frequency of the inverter to achieve the effect of reducing the speed of the winding motor to ensure the safety of the operator, the operator of the textile operation due to improper operation, causing damage, effectively improve the safety of Winding Machine.
