Abstract
A method for real-time measuring the thickness of the planar fibre product and the orientation of fibres features that a light beam is perpendicularly emitted on to the surface of said planar fibre product, and two groups of scattered signal receivers, which are mutually perpendicular and respectively connected to signal transmission system and in turn signal processing system are arranged at the same side of incident light beam. The sum of two signals is the real-time density coefficient of said product and their difference is the real-time orientation of fibres.
Description
Technical field
The invention belongs to the application of light, particularly utilize the scattering of light principle the thickness of fiber assembly planar products and the detection of the fiber degree of orientation.
Background technology
The fiber assembly planar products, the degree of orientation that as the surface density of non-weaving cloth, paper is usually said thickness and fibr tissue plays crucial effect to the physical performance index of product, they also are directly connected to the economic benefit of product, produce specification product, promptly how within the specific limits with every control indexes, dynamic, the real-time thickness of production product and the means of the fiber degree of orientation of detecting at first should be arranged, and in time the adjusting process parameter is reduced to minimum with production loss.At present, there is data to show, existing dual mode testing product thickness, a kind of radioactive isotope tester that on production line, is provided with, the huge injury that this radioactive material confrontation human body and environment cause has fundamentally limited promoting the use of of product; Another kind of with transmittance or principle of reflection, with incident intensity coefficient and transmitted light or intensity of reflected light index contrast as the coefficient of estimating product thickness, this method can only detect product thickness, can not the detection fibers degree of orientation, and range of application is restricted.
Technical scheme
The object of the invention is to invent a kind ofly carries out the method for the Real-time and Dynamic Detection object thickness and the fiber degree of orientation with light to the fiber assembly planar products, both pollution-free, convenient again, and stable performance, dynamic response are good.
The present invention is at a branch of directional light of vertical direction incident on detected fiber assembly planar products plane; Arrange orthogonal two groups of scattered light signal receivers at the incident light source homonymy, wherein one group parallel with product direction of motion, and the acceptance angle of scattered light signal receiver and product plane are 15～85 degree angles, another group is vertical with product direction of motion, and the acceptance angle of this group scattered light signal receiver and product plane are 15～85 degree angles; Above-mentioned two groups of scattered light signal receivers connect signal transmission system respectively, signal transmission system is connected with signal processing system, real-time bulkfactor two groups of signal numerical value and that be described product, the difference of two groups of signal numerical value are the real-time degree of orientation coefficient of described product fiber.
The present invention adopts the thickness and the fiber degree of orientation of light scattering determining fiber assembly planar products, by signal transmission system and disposal system, the coupled computer screen display, can observe thickness, change curve and the fiber degree of orientation, the change curve of product intuitively, adjust the raw materials for production import by control again, can in time detect, control in real time the product thickness and the fiber degree of orientation, to guarantee that production quality control is in scope of design.
Simultaneously, the acceptance angle of two groups of scattered light signal receivers of the present invention and the angle on planar products plane are respectively 30 degree, purpose be make two groups of signal numerical value and be in simultaneously with difference and be fit in the numerical analysis scope, it is more true to nature to detect the dynamic response effect.
