Description

The wrapped tenslator of a kind of winding machine

Technical field

The utility model relates to a kind of electrical machine equipment control device of wires and cables industry production winding wire product, the wrapped tenslator of especially a kind of winding machine.

Background technology

The wrapped tenslator of existing winding machine is mainly used 2 kinds of methods below: magnetic powder cluth tenslator, need speed adjustment unit (as frequency converter, servomotor) and tension force controller, poor linearity, failure rate is high, maintenance cost high (often will change magnetic), magnetic powder brake/magnetic powder cluth poor reliability; Directly closed-loop tension control device, needs speed adjustment unit, tension force controller and tension pick-up, and tension force control is steady, and tension force is visual, easily vibrates but debug tension system when bad.

Summary of the invention

The purpose of this utility model aims to provide a kind of wrapped tenslator of winding machine that does not adopt magnetic powder cluth, do not need tension pick-up.

The technical scheme that the utility model is taked is: the wrapped tenslator of a kind of winding machine, is made up of Programmable Logic Controller, man-machine interface, wrapped tep reel tachometer generator, servo-driver, servomotor.Man-machine interface is connected with Programmable Logic Controller by RS485 bus; The pulse signal of wrapped tep reel tachometer generator output is connected to the input pulse counter input of Programmable Logic Controller; The torque of Programmable Logic Controller output is connected to the input of servo-driver to determining voltage signal; The voltage input end of servomotor is connected to the voltage output end of servo-driver.

Described man-machine interface model is MT506SV3 touch-screen, described Programmable Logic Controller is the Delta DVP-10SX that includes D/A converter, described wrapped tep reel tachometer generator is Hall element, described servo-driver is Delta ASDA-B2 type servo-driver, and described servomotor is Delta ECMA type servomotor.

The beneficial effects of the utility model are, apparatus structure is simple, man-machine interaction intuitive and convenient, and all building blocks are all ripe general industrial control products; Without tension pick-up, adopt the mode that changes servomotor output torque to realize indirect permanent tension force control, device reliable and stable work.

Embodiment

With reference to Fig. 1, the wrapped tenslator of winding machine described in the utility model is made up of Programmable Logic Controller 1, man-machine interface 2, wrapped tep reel tachometer generator 3, servo-driver 4, servomotor 5.Programmable Logic Controller 1, for including the Delta DVP-10SX of D/A converter, is the control core of described device; Man-machine interface 2 is selected MT506SV3 touch-screen, is connected with Programmable Logic Controller 1 by RS485 bus, shows for control setting parameter and the state of a control of described device; Wrapped tep reel tachometer generator 3 is Hall element, and the pulse signal of output is connected to the input pulse counter input of Programmable Logic Controller 1, for measuring the rotating cycle of wrapped tep reel; Servomotor 5 is Delta ECMA type servomotors, and object is to drive twining package tape disc spins; In Programmable Logic Controller 1, the torque of D/A converter output is connected to the input of servo-driver 4 to determining voltage signal, and servo-driver 4 is selected Delta ASDA-B2 type servo-driver; The voltage input end of servomotor 5 is connected to the voltage output end of servo-driver 4.

Wrapped tension force control is realized by the control program in Programmable Logic Controller 1; Servo-driver 4 is operated in torque control model, realizes torque closed-loop control servo-driver 4 is interior; In wrapped tep reel external diameter one timing, the torque of controlling servomotor is constant, the constant tension of band; In the time that wrapped tep reel external diameter changes, only need the output torque of corresponding change servomotor, accomplish indirect permanent tension force control.As shown in Figure 2, concrete steps are wrapped tension control method:

Step 1, inputs the primary datas such as the original outer diameter, film band thickness, band tension force of wrapped tep reel;

Step 2 is read in the twining package tape disc spins number of turns from input pulse counter;

Step 3, according to the external diameter of the original outer diameter of wrapped tep reel, film band thickness, the current wrapped tep reel of twining package tape disc spins number of turns calculating;

Step 4, calculates given torque and exports servo-driver to according to the external diameter of current wrapped tep reel and given tension force, returns to step 2.
