Description
Technical field
The present invention relates to a kind of apparatus and method of monitoring the strip material density anomaly, particularly a kind of apparatus and method of harmless continuous monitoring strip material density anomaly.
Background technology
The density anomaly of strip material weight quality for product in commercial production plays critical effect.Present stage, the monitoring method for the strap-like objects density anomaly mainly was divided into two kinds: a kind of is that object is diminished sampling at random, then through the density to the samples weighing computing object, the density anomaly of judgment object again.This method is the sampling monitoring that diminishes that needs artificial participation, can not reflect the density anomaly of whole object, can only estimate the roughly Density Distribution situation of object according to the sampling density value.Another kind method is to metal band-shaped material and the homogeneity of the real-time monitored density of radiometric method that adopts; Though this method can realize can't harm continuous detecting and degree of accuracy is higher; But cause damage because radioactivity is known from experience the people, energy requirement is higher simultaneously, can't extensively apply in the commercial production.
Summary of the invention
The present invention aims to provide a kind of "dead" and can accomplish the apparatus and method of continuous non-destructive monitoring strip material density anomaly.
The present invention realizes through following scheme.
A kind of device of harmless continuous monitoring strip material density anomaly; Comprise measuring unit, division circuit and computer equipment; Described measuring unit the includes electronic-weighing equipment from bottom to up---axis of rolling---abutment ring---motor; The axis of rolling is upright on the electronic weighing device; Motor is connected with the axis of rolling through abutment ring, and motor gives the power that the axis of rolling laterally rotates and do not give power longitudinally through abutment ring, and the assurance axis of rolling does not exert an influence for the relative weight of measured strip material (be strip material to pressure that electronic weighing device produced); The electronic-weighing equipment of said measuring unit is connected with division circuit through data line, transmits the relative weight data to it; The motor of said measuring unit is connected with computer equipment with division circuit respectively through data line, realizes the motor control signal to the working time of division circuit transmission motor data and receiving computer equipment respectively; Division circuit is connected through data line or wireless mode with computer equipment, realizes that the data that division circuit is calculated transmit to computer equipment; Division circuit adopts existing associated electronic device commonly used to get final product, and computer equipment then adopts existing routine to possess signal reception, data processing, control and shows that the equipment of output function gets final product.
More accurate for the monitoring result that makes above-mentioned monitoring device, this device also comprises the flattening roller parts, in order to the strip material of leveling measurement.
A kind of method of harmless continuous monitoring strip material density anomaly; Adopt the device of above-mentioned harmless continuous monitoring strip material density anomaly; The driven by motor axis of rolling rotates; Set the constant linear velocity value and keep by connected computer equipment, the control signal of setting value is sent to motor, strip material is moved with the uniform linear velocity coiling axis of rolling through data line; The relative weight data that are continuously winding in the strip material on the axis of rolling that electronic-weighing equipment will obtain are sent in the division circuit through data line, and then be sent in the division circuit through data line the working time of motor.The volume of material relative density=material relative weight/material, material volume=length of material * material width * material thickness is for every coil strip material of measuring; Its thickness is consistent with width setup; Therefore the volume of this roll of material just is proportional to the length of material, because linear velocity has been set at constant speed, is motor working time so length is proportional to the coiling time again; Just volume is proportional to the coiling time, i.e. the time of motor movement.Therefore division circuit is after receiving relative weight data and motor movement time data; By formula: relative weight/run duration is calculated and is obtained relative density; The relative density signal is sent to the coupled computer equipment that connects; Computer equipment changes according to the relative density signal monitoring relative density that receives, if relative density does not change, then the output signal of division circuit is exactly the level of approximation straight line; If relative density changed in certain time period; Then export signal and just demonstrate corresponding fluctuation variation, computer equipment is converted into relative density by above-mentioned principle with the relative density signal and changes oscillogram output, from oscillogram, just can observe the variable density situation of strip material.
Also can in computer equipment, set the higher limit and the lower limit of relative density in advance, when the relative density value that records exceeds higher limit or is lower than lower limit, send the density anomaly alerting signal.
For making monitoring accurately, strip material is before being wound to the axis of rolling, earlier through the flattening roller leveling.
Compared with prior art, the present invention has following obvious advantage:
1. do not adopt radioactivity equipment in apparatus of the present invention, environmental friendliness is widely used.
2. monitoring device of the present invention and method can be implemented the density anomaly monitoring to strip material on the one hand under lossless case, can realize the automatic monitor for continuously of density anomaly on the other hand and possess the Realtime Alerts function.
3. monitoring device of the present invention and method are to the similar strip material of more detected consistent in density; Elder generation's manual work records their absolute density value; Again according to the relative density value that records; Just can set up the relation curve or the conversion formula of such strip material relative density and absolute density, can also calculate the absolute density value of such other strip material in view of the above in real time.
