Description

Automatic tester tester of fibre diameter homogeneity
Up to now, domestic and international fiber evenness, the particularly detection means of raw silk evenness, still the seriplane test method of at first reinstating based on the U.S..Its main points be with the raw silk sample in accordance with regulations burst shake and be around on the special blackboard, the reference standard model is with its uniformity coefficient of artificial visually examine, as one of important indicator of raw silk quality and grade.This ancient method restricts because of being subjected to factors such as human body situation, eyesight difference, and its inaccuracy is conspicuous.For trying to achieve improvement, the evenness testing machine that Wu Site type evenness test instrument that existing at present Uster, Switzerland (USTER) company produces and the raw silk inspection of Japanese Yokohama are manufactured experimently.
Wu Site evenness test instrument is used capacitor and is obtained detection signal as sensor, is mainly used in cotton spinning and detects, and detects still under test to raw silk.Its problem is that testing result is not consistent with sight (blackboard approach) assay, and differentiation is big and detection speed is also slower, is about a thirtieth of artificial sight detection.Japan's Yokohama evenness testing machine is then made sensor with resistance strain gage, the monofilament tension variation of promptly getting under certain elongation is a detection signal, its detection speed higher though (can examine 25 threads simultaneously) but its apparatus structure is huge, testing result is same bigger with the not consistent difference of sight (blackboard approach) detection.Above-mentioned two pick-up units also require to use under the constant temperature and humidity condition, and promptly all harsh to the environmental requirement condition, general factory is difficult for accomplishing.
Task of the present utility model is: formulate a kind of fiber evenness automatic detection device that does not rely on the traditional blackboard method of giving full play to the again strong point of human eye.This device comprises darkroom 1, blackboard 2, detects dolly 3, the sample of signal of fiber evenness and multiplying arrangement 4, electric light source 5, chromacoder 6, power supply 7, traction motor and control device 8 thereof, microcomputer 10, printer 11, track 12, travel switch 13, instrument stand 14, cable 15, carrier tape traction adhesive 16 and driving wheel group 17 etc. partly.On the blackboard 2 in accordance with regulations burst shake around measured object fiber 9(such as raw silk) side stand rearways is loaded in the darkroom 1 (for the darkroom component part), press control knob, starting traction motor 8, detection dolly 3 promptly is pulled in darkroom 1 middle orbit, 12 upper edge blackboards 2 and advances, until its terminal, by travel switch 13(tongue tube) control Huan Xiang And returns the original place automatically, stops by another travel switch (tongue tube) control.Be contained in the fiber evenness sample of signal that detects on the dolly 3 and multiplying arrangement 4 promptly in dolly 3 advances process along blackboard 2 after electric light source 5 irradiates lights, tested fiber 9 reflected light are obtained Guang Dian Xin And amplification, reach chromacoder 6 through cable passage 15, convert the electric signal that is suitable for microcomputer 10 inputs by this device to and after microcomputer 10 is handled, be printed as the test basis of testing result file as tested fiber by printer 11.Microcomputer 10 is started working simultaneously with sample of signal and multiplying arrangement 4, detects once end, and microcomputer draws testing result immediately, and All Time is 7 seconds.
Of the present utility modelly be characterised in that one detects dolly 3 and the sample of signal of fiber evenness and multiplying arrangement 4, the detection evenness of being shaken the tested fiber (containing cotton, silk and regenerated fiber) on the blackboard 2 automatically in darkroom 1.Neither be subjected to the restriction of human eye factor not to be subjected to the , And that influences of ambient light to draw testing result immediately again through MICROCOMPUTER PROCESSING.Not only consistent substantially with artificial sight (blackboard approach) testing result but also artificial sight detects greatly accurately, rapidly, and can require to be equipped with different microcomputers according to difference and form accurate and universal device.
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Accompanying drawing 1 is this device installation diagram, and 1800 millimeters of darkroom 1 length are wide 450 millimeters, high 620 millimeters, be positioned on the instrument stand 14 of same length and width, its trailing flank, bottom surface and biend are that 0.5 millimeter movable iron plate is formed by thickness, and operating surface is then hidden by blackboard 2 and forms.The sampling of fiber evenness photosignal and multiplying arrangement 4 and symmetrical two electric light sources of installing 5 are housed on the detection dolly 3 in the darkroom 1.Tested fiber 9 its illumination angles on this light source irradiation blackboard 2 are 45 to 60 degree, after the 4 picked-up Xin And amplifications of fiber 9 reflected light confession sample of signal multiplying arrangement, supply with the chromacoder 6 that is placed on the instrument stand 14 through cable passage 15, print the assay file by printer 11 after microcomputer 10 is handled through still being defeated by after its conversion by cable 15.7 of power supplys are public by each instrument, and electric therebetween connection is finished by cable passage 15.Dolly 3 is driven by traction motor and control device 8 thereof through carrier tape traction adhesive 16 and driving wheel group 17, by determining that speed 0.2 meter per second moves until terminal at track 12 upper edge blackboards 2, by the 13 control commutations of tongue tube travel switch, stop by another tongue tube control by return reposition And with speed.The skeleton of darkroom 1 and instrument stand 14 is welded by 20 * 20 * 2 equal angles.
