[specific embodiment]
Will further understand the present invention through following embodiment.
Preparation facilities as shown in Figure 1 comprises servomotor 3,7,8 and motor servo driver, tension pick-up 4, PMAC controller 6 and the composition such as guide system, core, steeping vat, creel that can conduct many glass fibres side by side.
Servomotor 3 is provided with encoder; One group of friction roller moves up and down on the leading screw 13 upper rails drive steel plate; Encoder connects PMAC controller 4; The tension error signal that draws in the PMAC controller 4 is delivered to the motor driver on the servomotor 3, and motor driver is installed on the servomotor 3, by the work of motor driver control servomotor 3
The friction roller of stationary roll frame 12 and moving mill frame 11 all is the cylindrical metal roller, and wherein 3 metallic roll are connected on the top moving mill frame 11, and steel plate is connected with leading screw 13, and leading screw 13 is connected with servomotor 3, and on leading screw 13 next doors two limit valves is housed.Other one group of friction roller is made up of 4 metallic roll, is connected on another piece stationary roll frame 12, and stationary roll frame 12 is connected with fixed frame.
When obtain initial tension (for example through walking around a pair of friction roller) through the glass fibre of steeping vat after to obtain tension force through two groups of friction rollers between; The tension signal that is transmitted by PMAC controller 4 determines two groups of distances between the friction roller, and the state (for example contact-making surface angle, transfer rate) of glass fibre between two groups of friction rollers.
Wherein hold glue in the steeping vat 2 and should be in the water-bath, for example keep 60 ℃ of constant temperature.
The tension signal that tension pick-up 10 records enters into PMAC controller 5; Compare computing with the tension value of setting; Export of the output corresponding torque of the corresponding signal of telecommunication, constitute the Tension Control that a complete closed-loop system realizes glass with control friction roller motor.
The guide structure belongs to state of the art in the filament-wound device; Can comprise a small machine, horizontal Control Shaft, leading screw and on Yarn-guiding mouth; Described horizontal Control Shaft and leading screw keep horizontal parallel, and the two ends of horizontal Control Shaft are connected on the leading screw biside plate and are fixed on a below of mouth body frame.One end of leading screw connects servomotor, the fiber after Tension Control during through Yarn-guiding mouth servomotor control down with reciprocal back and forth the moving of core width.
The 5 control constant linear velocity operations of PMAC controller, the guide motor carries out accompany movement according to the position feedback of spindle motor, and those skilled in the art can rationally arrange the inlet angle of glass fibre (yarn) according to technological requirement.In order to satisfy process requirement of equipment, need program and tension value carried out the control of real-time continuous and the motion of guide motor during to diverse location in main axis rotation.
During operation, at first, core is installed, equipment carries out program initialization, glass fibre pretension, starting drive.
Make through the friction roller group between yarn roller 1 and the steeping vat 2 to make glass fibre have initial tension, can more help to make the abundant impregnation of fiber like this.
Secondly, tension pick-up 10 is measured tension value on the fiber behind the impregnation, sends PMAC controller 5 to, and PMAC controller 5 provides tension control signal through calculating and sends the driver of the servomotor 3 of tension regulating system to.
Fiber is through tension pick-up 10 and velocity sensor 9; Tension pick-up 10 and velocity sensor 9 record the tension value on the fiber and walk yarn speed, and this signal is transferred to PMAC control cabinet 5, through a series of calculating; Obtain fiber tension value and velocity amplitude; And itself and preset value compared, confirm existing error, PMAC control cabinet 5 with this error propagation to servomotor 3.
Then; The displacement and angle, the length of silvalin bundle on stationary roll of friction roller 11 on the servo driver drives servomotor 5 control leading screws 13; Change the contact area between friction roller and the fiber, make the preset value of tension force and tension force of fiber in error range.
The control signal that provides through PMAC controller 5 drives moving up and down of friction roller on the servomotor 3 control leading screws 13.Servomotor judges that whether the actual tension value is greater than the tension force preset value; If greater than one group of friction roller 11 being connected with leading screw 13 move up; Distance between two groups of friction rollers diminishes, angle increases; Fibre length between two groups of friction rollers shortens, and fiber is pine slightly, thereby its tension value is reduced until being returned to preset value.
If the actual tension value is less than the tension force preset value, the one group of friction roller 11 that then is connected with leading screw 13 moves down, and the fibre length between two groups of friction rollers increases, and the angle between fiber and the friction roller reduces, and makes that tension value increases to preset value on the fiber.Through notifying two groups of friction rollers 11, fibre length and the contact angle between fiber and the friction roller between 12; It is the contact area between friction roller and the fiber; Control fiber tension, make fiber tension in system's running, be in all the time with the tension force preset value within the scope that error allows.
The change of tension force can be regulated through press-down type or top uncoupling type, like Fig. 3, shown in 4.
At last, fiber is transferred to mould core (not drawing among the figure) through Yarn-guiding mouth 2 with glass fiber yarn.
In tension controller 4, can change the friction roller that leading screw 13 drives into upwards walk about contact area, thereby increase the tension force of fiber with increase glass fiber yarn and friction roller, as shown in Figure 4.
Perhaps alternatively adopt the design of cam-type; With bent axle and go up crank, friction roller is replaced with cam, opens a smooth groove of goose egg shape on the cam, because the continuous rotation of cam; Make the change of the contact area of fiber and friction roller; Thereby the change fiber tension makes itself and tension force preset value in the allowable error scope, and is as shown in Figure 5.
Perhaps alternatively adopt the rotary design of central shaft; By one group of four friction roller; Wherein middle two friction rollers are coupled together by an axle and can in the shaft diameter scope, rotatablely move with this axle; Change the contact area between fiber and the friction roller with this, thereby change the tension force on the fibre bundle, as shown in Figure 6.
Or adopt crank type design alternatively; Through yarn being placed the homonymy of friction roller, and at bent axle of this side configuration, the several cranks of configuration on the bent axle; Connect friction roller respectively; These friction rollers are followed bent axle and are moved up and down, so that the contact area of glass fiber yarn and friction roller changes, thereby make in the scope that tension value and preset value on it remain on allowable error as shown in Figure 7.
Through above-mentioned composition; Fiber tension can be realized real-time Monitoring and Controlling in the device among the present invention; And required tension value of each stage is stored in the PMAC controller in advance, the tension condition that in the Wiring apparatus running, can come the real time altering fiber according to the preset tension value of difference.Device of the present invention can be used for producing the fiberglass type leaf spring, the tension force in process of production of the tension adjustment leaf spring through changing glass fibre, and generation manufacture process and properties of product with the adjustment leaf spring have good flexibility and suit property.
