The system comprises a controller for controlling the running of a DC motor of an uncoiling or coiling device, an encoder capable of collecting running state information of the DC motor, and a PLC module that can conduct centralized processing of running parameters and output control signals to the controller. A motor number-of-revolution signal output end of the encoder is connected to a number-of-revolution signal collection module, a signal output end of which is connected to the PLC module. The system can produce relatively accurate, stable and linear coil diameter signals in a strip production equipment control system. And the system is simple in composition and low in implementation cost.
Description
Technical field
The utility model relates to a kind of detection system and detection method that band coil diameter is detected of being used in the equipment such as aluminium strip (paper tinsel) rolling equipment, paper making equipment, hoisting equipment.
Background technology
In the production of band, for uncoiling, the coiling process of band, the real-time coil diameter of band is that production run is controlled the definite important evidence of parameter.For example, in the rolling equipment of aluminium strip (paper tinsel), the Measurement accuracy of coil diameter is the assurance that coiling tension is effectively controlled, and it has determined that can coiling machine work and batch the quality of effect, is directly connected to production and the product quality of milling train.In existing band production equipment, coil diameter signal obtain general employing laser range finder, ultrasonic range finder, the device such as linear potentiometer is measurement coil diameter directly.But, laser range finder, ultrasonic range finder, linear potentiometer is subject to environment (temperature, illumination, vibrations, distance, position etc.) impact larger.In detection, tend to occur fluctuation, dead band, the signal of detection can not be linear.Have influence on greatly coil diameter quality.Cause sometimes great adverse consequences.Certainly, have powerful laser range finder, ultrasonic range finder is affected by environment less, and still, price comparison is high, economical not.
In the control system of the batching of most of band production equipments, uncoiling, conventionally can use scrambler to gather the tach signal of direct current generator, but the foundation that scrambler is only controlled as rotating speed.And scrambler not only can detect the rotating speed of motor accurately, and can accurately detect the number of turns that motor rotates in certain period.The control system of the batching of existing band production equipment, uncoiling is not used to this detected parameters of scrambler.
Summary of the invention
Technical problem to be solved in the utility model is provide a kind of and can in the control system of band production equipment, produce relatively accurate, stable, linear coil diameter signal, and system to form the band coil diameter detection system simple, implementation cost is low.
Band coil diameter detection system of the present utility model includes controller for the running of the direct current generator of uncoiling or taking-up equipment is controlled, can gather the scrambler of direct current generator operating condition information, can focus on and to the PLC module of controller output control signal operational factor; The output terminal of the motor rotating cycle signal (Z signal) of described scrambler is connected to a lap signal acquisition module, the signal output part of lap signal acquisition module is connected to PLC module, for PLC module, according to lap signal, calculate band coil diameter, as controlling foundation.
Described lap signal acquisition module and controller are integrated in the DC transformer that a model is DCS 800 (ABB AB's product).
Advantage applies of the present utility model exists: 1, relatively existing detection method has reduced the equipment investments such as laser range finder, ultrasonic range finder, linear potentiometer, directly utilize the scrambler in original DC motor control system to gather lap signal, greatly reduce equipment cost; 2, testing process is not subject to temperature, illumination, and the impact of the running environment such as vibrations, accuracy of detection is high; 3, utilize the DC transformer of DCS 800 of ABB AB as controller and lap signal acquisition module, simplified system formation, further reduced cost.
Accompanying drawing explanation
Fig. 1 is systematic schematic diagram of the present utility model.
Embodiment
As shown in the figure, this system include controller for the running of the direct current generator of uncoiling or taking-up equipment is controlled, can gather direct current generator operating condition information scrambler, can focus on and to the PLC module of controller output control signal operational factor; The output terminal of the motor rotating cycle signal (Z signal) of described scrambler is connected to a lap signal acquisition module, the signal output part of lap signal acquisition module is connected to PLC module, for PLC module, according to lap signal, calculate band coil diameter, as controlling foundation.Lap signal acquisition module and controller are integrated in the DC transformer that a model is DCS 800 (ABB AB's product); By the A+ of the scrambler of 8 lines, A-, B+, B-, Z+, Z-, U+, 0 each signal output part access DCS 800 DC transformer input ends, Z signal is wherein motor rotation circle lap signal.In this system operational process, in PLC module, calculate in accordance with the following methods current coil diameter: first according to the initial band THICKNESS CALCULATION on drum diameter and reel, obtain initial coil diameter Dcs, the thickness of strip H that combination is reeled again, the motor rotating cycle Njq that scrambler collects and the no-load voltage ratio i of wheel box, calculate current coil diameter Ddq; Current coil diameter Ddq=Dcs+Njq/i * 2H while batching, current coil diameter Ddq=Dcs-Njq/i * 2H during uncoiling.
Claims (2)
1. a band coil diameter detection system, include controller for the running of the direct current generator of uncoiling or taking-up equipment is controlled, can gather direct current generator operating condition information scrambler, can focus on and to the PLC module of controller output control signal operational factor; It is characterized in that: the output terminal of the motor rotating cycle signal of described scrambler is connected to a lap signal acquisition module, and the signal output part of lap signal acquisition module is connected to PLC module, for PLC module, according to lap signal, calculate band coil diameter.
