Description of drawings
Fig. 1 is the structure principle chart of system of the present invention.
Embodiment
As shown in Figure 1, fixed frame 5, correlation optical fiber head group and the counter-controller that is attached thereto 10 constitute complete block material counter.It is firm that the optical fiber head group is installed in rigidity, and on the accurate in size fixed frame 5, fixed frame 5 is installed on the support of production line 7 again.Slightly not rocking of streamline support can impact counting.The installation site of fixed frame 5 can be chosen in the moisture, the powder that are subjected on streamline or the material simultaneously influences smaller position.The optical fiber head of bottom may be affected when some on-the-spot mounting condition is poor, this drawback can by in the counter-controller to the monitoring of light intensity, cross low the warning by light intensity, need to remove surperficial rubbish prompting and solve.
Wherein, the optical fiber head group of described correlation comprises the launching fiber head 1,3 that respectively has the row setting of one's own and receives optical fiber head 2,4.
It is horizontal that the optical fiber head of described one-tenth row is walked hopper along material, or vertically, or oblique unidirectional setting; Or the optical fiber head of described one-tenth row is the two-way settings that intersect vertically substantially.For example, among Fig. 1, form vertical optical fibre set, constitute light plane network longitudinally by launching fiber head 1 and reception optical fiber head 2.Form horizontal optical fibre set by launching fiber head 3 and reception optical fiber head 4, constitute horizontal light plane network.Laterally with light plane network longitudinally, add advancing of 7 materials on the production line, formed the stereoscanning network.
The light emission angle 8 of ordinary optic fibre head is bigger, adopts the correlation method can realize the point-to-point connection of light 9, and refraction, the diffraction that emission light is produced in traveling process enters the influence that receives optical fiber head and can drop to minimum.
Spacing distance between each optical fiber head of described every row optical fibre set is less than 1/4 of the minimum dimension of lump material, and the quantity of optical fiber head can cover width and the height that production line is walked hopper simultaneously.
Optical fiber head adopts small-bore optical fiber head (φ 3 and following), and the principle of choosing is below 1/10 of single material minimum dimension for the optical fiber head diameter.
The light source that adopts in the optical fiber is the light source of single wavelength, does not contain the light source of this wavelength in natural light and the common light substantially.Some novel light may contain the composition of this light source of part, if influence surpasses the proportion of the order of magnitude of light resolution in the counter-controller, then replaceable this environment light.
When the material surface is that minute surface or material are the easy colors that reflect such as white, refinement light reception sleeve 15 on the optical fiber head 2 and 4 can received, the inwall of sleeve will absorb the non-perpendicular light that the overwhelming majority produces because of refraction, diffraction, and what reception optical fiber head 2 and 4 received mainly is the vertical light of launching fiber head 1 and 3 emissions.

The information of photoelectric signal processor is sent to counting algorithm processor 12.But counting algorithm processor record, the length, width of the current material of accumulative total, highly and the blank distance between the material, time that material passes through, by calculating horizontal vertical physical dimension information, material gait of march and time information, calculate the information such as effective length and width height, volume of the current material that passes through, the lump material sample information of preserving with plurality of specifications lump material sample data memory block 16 contrasts.Comparative information comprises that thin material, two-fold material information, triple-lap material, doubly-linked material, three connect material and other connects material, two 3 (four material) material, three or four material information such as (five material) more.In actual applications, by cooperating with the reasonable of upper production line, only with wherein part comparison information and the precision of counting can be brought up to ten thousand/more than, far surpass the accuracy of detection of fluid.
Possesses the automatic abstraction function of sample characteristics in the counter-controller 10.Before to a kind of new lump material counting, must be by the lump material sample of some.Sample must single only pass through.The quantity of choosing sample is mainly considered the neat appearance degree of material, and whether the attitude on streamline is regular, the counting precision of requirement etc.Simple mode is to choose to require the sample size over half of counting precision denominator to get final product, as requires 1/10000 precision, and then the sample size of freely choosing more than 5000 gets final product.Another kind of mode is to choose to be tending towards two extreme typical samples on the material profile, and the sample size that this mode is chosen can reduce in a large number.
The switching of production line production material is sent instructions by upper system, is sent to counter-controller by bus communication and carries out.
Count information after treatment is sent to upper system by the upper system communication processor 13 in the counter-controller, and upper system can put the case number of elements according to the count information statistics that receives, reject the speed of substandard products or control production line.When the material on the production line passes through the count detection critical point, optical fibre set is with the physical dimension information of the current material of advancing of the velocity sweeping of microsecond level, the effective length and width height that comprises current material, and with the time of passing through, synchronous driving is to counting algorithm processor, the real-time accumulated above-mentioned information of APU.After current material passed through, APU calculated by information such as the high aggregate-value of material length and width, mean value, adhesion degree value, overlapping degree values.Then with internal memory in the sample information of preserving compare, the count results of comparison is sent to upper system by upper system communication processor.
Adopt simple in structure, the fiber optic network that reliable correlation optical fiber constitutes, form the counting critical point in the suitable position of production line, the lump material that passes through is carried out stereoscanning on the profile, after information after will scanning be sent to counter-controller 10, controller is compared the scanning information received and the sample information of internal record, determine the number of elements of the current lump material that passes through, can obtain simultaneously some additional information, if any the lump material of external packing empty bag whether, whether lump material is incomplete or the like, offers the upper system of production line and does bad part eject and use.
