Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, the film take-up of the present embodiment, comprise rolling support 11, winding motor and rolling-up mechanism, rolling-up mechanism comprise opposing parallel setting close to roller 12 and rolling steel pipe core 13, bearing 14 and rolling support 11 sliding block joint are sat by the first band in two ends close to roller 12, rolling steel pipe core 13 is fixedly connected with rolling support 11 by steel pipe iron core support 15, and the center of circle of fixing rear rolling steel pipe core 13 is on same level line with the center of circle close to roller 12, first band is sat bearing 14 and is provided with Laser emission receptor 21 near the side of rolling steel pipe core 13, steel pipe iron core support 15 is provided with the bevelled mirror 22 corresponding with Laser emission receptor 21.Rolling support 11 is also provided with the cylinder 10 paralleled with oil cylinder 17, and the rod end and first of cylinder 10 is with and is sat bearing 14 and be fixedly connected with, and this cylinder 10 sits the stability of bearing 14 linearly slide rail 16 movement for improving the first band, avoid it to tilt.The conveniently data display of Laser emission receptor 21, rolling support 11 is also provided with Warning light, and this Warning light is connected with the control system in film take-up.
In the present embodiment, rolling support 11 is provided with line slide rail 16, and the bottom that bearing 14 sat by the first band is arranged on line slide rail 16 by slide block, and its top is fixedly connected with rolling support 11 by oil cylinder 17.This oil cylinder 17 can promote under the effect of actuating unit the first band sit bearing 14 linearly slide rail 16 move forward and backward.
The conveniently even rolling of film, rolling-up mechanism also comprises jockey pulley 18, and this jockey pulley 18 is held by the second band seat axle 19 and is arranged on close to immediately below roller 12.
Rolling support 11 is provided with the line slideway 111 and ball-screw 112 that parallel, line slideway 111 is by being fixed on slide block on rolling support 11 and rolling support 11 sliding block joint, ball-screw 112 is by being fixed on screw slider on rolling support 11 and rolling support 11 is rotationally connected, inside because of screw slider is provided with the screw thread matched with ball-screw 112, and the end of ball-screw 112 is connected with winding motor, so ball-screw 112 rotates under the effect of winding motor and then drive rolling support 11 to move forward and backward.
Working process: winding motor drives ball-screw 112 to rotate, the screw slider be fixed on rolling support 11 drives rolling support 11 to move back and forth, and line slideway and slide block are auxiliary fixing and guiding movement.Rolling support is 11 under the motion of ball screw 112, and close close to roller 12 and rolling steel pipe core 13, oil cylinder 17 promotes the first rolling bearing units 14 under systemic effect, and then promotes to fit close to roller 12 and rolling steel pipe 13.The laser beam irradiation of now Laser emission receptor 21 transmitting is on the bevelled mirror 22 of rolling steel pipe core support 15, bevelled mirror 22 by laser beam reflection on Laser emission receptor 21, form range finding distance, concrete data are presented on the display instrument of film take-up.Range finding distance close to roller 12 two ends ensures in nominal error scope ± 1mm.In Laser emission receptor 21 works, real time data contrast is close to the range finding distance at roller 12 two ends, and the error at two ends is in ± 1mm, and the Warning light be arranged in film take-up does not work.As real time data contrast appearance >=2mm, will trigger alert lamp, prompting increases oil cylinder working-pressure in time, till Warning light is eliminated.The effect of this pinch device is because of close to the restriction of roller 12 its length, causes changing close to roller 12 and rolling steel pipe core 13 parallelism, affects the rolling of film; Utilize ranging device based on laser phase method to adjust parallelism close to roller 12 and rolling steel pipe core 13 in time, thus reach and film compression processed online and do not affect film quality, meet manufacturing technique requirent, saving floor time increases production capacity.
Laser phase method range finding groundwork: as shown in Figure 2, ranging phase method by measuring the phase displacement φ produced after modulated light wave elapsed time t, thus tries to achieve the distance D that light wave passes by.As shown below, A point represents the launch point of modulated light wave, B point represents tested reflecting surface, A ' represents the acceptance point of light wave after tested surface reflection, distance between A and A ' 2 is exactly the distance that light wave is passed by, it equals 2 times of testing distance D, and in figure, φ just represents the phase displacement of light wave in roundtrip.
Light wave phase place in communication process is constantly change, represents optical wavelength with λ, then often propagate a wavelength, and phase place is change 2 π just.So the pass that distance D, light wave come and go between phase displacement φ and optical wavelength λ is:
D＝λ/2*φ/2π(1)
Definition λ/2 are for surveying chi length L, and φ/2 π is equivalent to the number of the long L of survey chi comprised in D.If make Ω=2 π N+ △ Ω, the N mantissa that to be positive integer or 0, △ Ω be less than 2 π in Ω in formula, then can be written as in (1) formula:
D＝L*[N+△Ω/π](2)
But the complete cycle issue N of phase displacement can not determine to draw, and can only measure wherein less than the phase displacement mantissa △ Ω of 2 π.In formula (2), if tested distance D is less than survey chi length L, then can determine D, and when D is greater than L, N is unascertainable, such D also just can not determine, causes Multiple solution.In order to address this problem, the survey chi that several length is different can be adopted in apomecometer, by they with the use of, make bigness scale chi with longer survey chi, make accurate measurement chi with shorter survey chi, so both can ensure the monambiguity measured, higher range accuracy can have been ensured again.Survey the corresponding modulation frequency τ of chi L for one, its pass is:
τ＝C/2L(3)
Phase laser distance measurement has direct modulation frequency mode and the indirect modulation frequency mode of continuous print two kinds of dispersion.In order to ensure necessary range accuracy, when the survey chi measurement of system just by two length, it is higher that the frequency of accurate measurement chi must be selected, and be generally tens MHz to tens MHz, and bigness scale chi is generally a hundreds of kHz, determined by the ranging of system and precision.The direct modulation frequency mode of dispersion be directly provide accurate measurement chi, bigness scale chi frequency for measuring, but like this span that regulates of system frequency is large, high to the requirement of system electronics, degree of stability is poor, realizes difficulty high.Just there is not these shortcomings in the indirect modulation frequency mode of continuous print.Its principle is: when with f1 and f2 two modulation frequencies, modulated light wave goes to measure same distance respectively, the phase displacement of two ripples is:
Ω1＝2πf1t＝2π(N1+△N1)
Ω2＝2πf2t＝2π(N2+△N2)
The difference of its phase place is:
△Ω＝Ω1－Ω2＝2π[(N1－N2)+(△N1－△N2)]
＝2π(N+△N)(4)
In formula:
N＝N1－N2
△N＝△N1－△N2
If when measuring this distance with difference frequency (f1-f2) as the modulating frequency of light wave, its phase displacement is:
△Ω’＝2π(f1－f2)t＝2π[(N1－N2)+(△N1－△N2)]
＝2π(N+△N)(5)
From formula (4), formula (5), to same distance do phase method measure time, the phase displacement that the difference of the phase displacement that two modulation frequencies are found range respectively equals to find range with the difference frequency of these two modulation frequencies and obtains.Even the value of (f1-f2) equals the frequency of bigness scale chi, and its phase displacement just can be calculated by two frequency f 1 with the order of magnitude and f2, overcomes the defect of the direct modulation frequency mode of dispersion.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
