The wrapped synchronous velocity control device of a kind of winding machine
Technical field
The utility model relates to the electrical machine equipment control setup that a kind of wires and cables industry produces winding wire product, the wrapped synchronous velocity control device of especially a kind of winding machine.
Background technology
In existing winding wire lapping device, haulage speed controller controlled winding line haulage speed, wrapped speed controller controls wrapped speed, and when haulage speed can be kept to stablize with wrapped velocity-stabilization, lay of lapping can keep stable.The interference that wrapped speeds control is subject to is few, when adopting driven by servomotor wrapping mechanism, easily accomplish wrapped velocity-stabilization, but winding wire traction element mechanical drive is more complicated, is difficult to keep haulage speed to stablize, and causes lay of lapping uneven.
Summary of the invention
The purpose of this utility model aims to provide the sync control device of the wrapped speed of a kind of winding machine.
The technical scheme that the utility model is taked is: the wrapped synchronous velocity control device of a kind of winding machine, be made up of PLC, servo-driver, servomotor, man-machine interface, haulage speed sensor, wrapped speed sensor, RS-485 bus, it is characterized in that: man-machine interface is connected with PLC by RS-485 bus; The output signal of haulage speed sensor delivers to the Speed Setting input end of servo-driver; The output signal of wrapped speed sensor delivers to the code device signal input end of servo-driver; Servo-driver is communicated with PLC by RS-485 bus 700; Servo-driver output drive signal drives servomotor to rotate.
Described man-machine interface is MT506SV3 touch-screen.
Described PLC is Delta DVP14ES00R2.
Described servo-driver 200 adopts Delta ASDA-B2 type servo-driver.
Described servomotor is Delta ECMA type servomotor.
Described haulage speed sensor is DC tachometer generator.
Described wrapped speed sensor adopts Delta encoded servo device MH4-25LN65CAD.
The beneficial effects of the utility model are, adopt winding wire haulage speed large for inertia as principal velocity, after lay of lapping is given, wrapped speed preset value keeps fixed proportion relation with actual winding wire haulage speed, even winding wire haulage speed changes, wrapped speed can make corresponding change, thus keeps the stable of lay of lapping.

Detailed description of the invention
With reference to Fig. 1, described winding machine wrapped synchronous velocity control device is made up of PLC 100, servo-driver 200, servomotor 300, man-machine interface 400, haulage speed sensor 500, wrapped speed sensor 600, RS-485 bus 700.PLC 100 is the CPU224 of S7-200 series, is the control core of described device; Man-machine interface 400 adopts MT506SV3 touch-screen, is connected with PLC 100 by RS-485 bus 700, for controling parameters setting and the state of a control display of described device; Haulage speed sensor 500 is for measuring the haulage speed of winding wire, and adopt DC tachometer generator to test the speed, the analog voltage signal of output delivers to the Speed Setting input end V-REF of servo-driver 200; Servomotor 300 is Delta ECMA type servomotor, rotates for driving wrapping mechanism; Wrapped speed sensor 600 is for measuring wrapped speed, and wrapped speed sensor 600 adopts Delta encoded servo device MH4-25LN65CAD, and it exports the code device signal input end CN2 delivering to servo-driver 200; Servo-driver 200 adopts Delta ASDA-B2 type servo-driver, is communicated, realize the exchange of status information and control information by RS-485 bus 700 with PLC 100, and output drive signal drives servomotor 300 to rotate simultaneously.
The synchro control of wrapped speed controls servo-driver 200 by PLC 100 and realizes.Servo-driver 200 is operated in speed follower state, and haulage speed is principal velocity, and wrapped speed is from speed, and Speed Setting comes from the voltage of Speed Setting input end V-REF; Principal velocity and carried out optimum configurations to determine by PLC 100 pairs of servo-drivers 200 from the proportionate relationship between speed.
In PLC, RS-485 bus is utilized to carry out data communication and information exchange is the routine techniques that those skilled in the art grasp.
