The motor comprises a main motor body and a take-up motor body. The servo driver comprises a first servo driver body and a second servo driver body. The mechanical structure comprises a paying-off wheel, a wire connection part and a take-up wheel. According to the tension control system of the wire drawing machine, the tension control system with the PLC as the core is designed, has a better control effect, is high in responding speed and small in over-adjustment, and has higher accuracy and stability and can meet the requirement for constant tension of the wire drawing machine.
Description
Technical field
The present invention relates to draw bench technical field, particularly relate to a kind of draw bench tension control system.
Background technology
Draw bench is the major equipment producing continuous fiber goods, its radical function is the fiber that the liquid flowed out leting slip a remark is drawn into certain fineness, and in certain winding displacement mode, its rule winding is become the cake of particular requirement, move back solution for next procedure, Split Down becomes marketable yarn or for weaving.
Draw bench, in take-up process, keeps the constant of tension force suffered by fiber yarn to be the essential condition ensureing follow-up quality of item.The quality and performance of fibre is closely related with the technological parameter in its production process again.A large amount of research and practice proves, in drawing process, tension force selects improper or tension force control instability, the loss of strength 20% ~ 30% of fibre can be made, and suitably and pulsation-free tension force can improve the application stress of fiber, give full play to the high powerful feature of lamination coating, fortifying fibre goods bear the ability of interior pressure, improve its fatigue resistance.If overtension, then between draw bench bobbins and jockey pulley, fiber yarn because of stressed excessive and be affected, even can be pulled off.Otherwise, if tension force is too small, then can form the phenomenon such as loose wire, sleave between jockey pulley and bobbins again, have a strong impact on the normal operation of production, reduce labor efficiency.Although traditional mechanical type controls automatically, pneumatic type controls automatically and hydraulic pressure drive control system simple and be easy to realize, the high dynamic response ability of this system, high precision and high-stability requirement cannot be met.
Summary of the invention
The present invention is intended to solve the deficiencies in the prior art, and provides a kind of stable, easy to operate draw bench tension control system.
The present invention for achieving the above object, by the following technical solutions: a kind of draw bench tension control system, is characterized in that, comprise PLC, motor, servo-driver, tension pick-up, ccd image sensor, preamplifier filter, A/D converter, physical construction, motor comprises main motor, take-up motor, servo-driver comprises the first servo-driver, second servo-driver, physical construction comprises actinobacillus wheel, wiring part, take-up pulley, actinobacillus wheel is connected with wiring part, wiring part is connected with tension pick-up, tension pick-up is connected with take-up pulley, the output of tension pick-up is connected with ccd image sensor, and the output of ccd image sensor is connected with preamplifier filter, and the output of preamplifier filter is connected with A/D converter, the output of A/D converter is connected with PLC, PLC respectively with the first servo-driver, second servo-driver is bi-directionally connected, and the output of the first servo-driver is connected with main motor, and the output of main motor is connected with wiring part, and the output of the second servo-driver is connected with take-up motor, and the output of take-up motor is connected with take-up pulley.
The invention has the beneficial effects as follows: it is the tension control system of core that the present invention devises with PLC, and this control system has good control effects, its response is fast, overshoot is little, has higher precision and stability, can meet the requirement of draw bench to identical tension.
Accompanying drawing explanation

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, a kind of draw bench tension control system, is characterized in that, comprise PLC, motor, servo-driver, tension pick-up, ccd image sensor, preamplifier filter, A/D converter, physical construction, motor comprises main motor, take-up motor, servo-driver comprises the first servo-driver, second servo-driver, physical construction comprises actinobacillus wheel, wiring part, take-up pulley, actinobacillus wheel is connected with wiring part, wiring part is connected with tension pick-up, tension pick-up is connected with take-up pulley, the output of tension pick-up is connected with ccd image sensor, and the output of ccd image sensor is connected with preamplifier filter, and the output of preamplifier filter is connected with A/D converter, the output of A/D converter is connected with PLC, PLC respectively with the first servo-driver, second servo-driver is bi-directionally connected, and the output of the first servo-driver is connected with main motor, and the output of main motor is connected with wiring part, and the output of the second servo-driver is connected with take-up motor, and the output of take-up motor is connected with take-up pulley.
In winding process, wire drawing with constant speed from actinobacillus wheel out afterwards through wiring part, tension pick-up, be finally wound on take-up pulley.In wire drawing winding process, gather drawing tensile force by tension pick-up to change, export tension force and transfer to PLC after ccd image sensor, preamplifier filter and A/D converter, PLC produces control signal by software algorithm process and exports to the first servo-driver and the second servo-driver, to control the rotating speed of main motor and take-up motor, reach the object controlling tension force.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that method of the present invention is conceived and technical scheme is carried out; or directly apply to other occasion, all within protection scope of the present invention without improving.
