Embodiment
The principle of work of this sensor is described for towel blank rip cutting equipment below.Towel blank rip cutting equipment arranges to stitch 2 corresponding floating cutters 6 with each rip cutting on blank transfer path, floating cutter 6 generally comprises floating mount 16, the lateral driver device of floating mount and the cutting motor 11 that is arranged on floating mount 16, floating mount 16 is fixed in the frame 7 of towel blank rip cutting equipment by horizontal rail 8, and the output shaft of cutting motor 11 is provided with and stitches 2 corresponding blades 18 with the rip cutting of towel blank.The lateral driver device of floating mount adopts traversing motor M and pinion and rack, and traversing motor M is fixed on floating mount 16, and its output shaft is connected by the frame 7 of pinion and rack with towel blank rip cutting equipment.
Referring to Fig. 1-Fig. 2, the utility model comprises CPU, optical transmitting set 19 and optical receiver 17, optical transmitting set 19 is installed on the below of towel blank, form primarily of the multiple light emitting diodes be distributed in transparent shell (as glass tube), be connected with power supply by current-limiting resistance R3 after multiple light emitting diode is connected in series.Due to light emitting diode arrangement density comparatively large (centre distance is 8mm), quantity is more, therefore also they can be divided into some groups, is connected after the light emitting diode often organized is connected in series by current-limiting resistance with power supply.The optical receiver 17 of multiple floating cutter shares an optical transmitting set 19, and therefore the length of transparent shell should be not less than the width of towel blank.
When seeking gap working sensor, multiple light emitting diode is lighted simultaneously, the thickness of rip cutting seam 2 and raphe transection 3 place towel blank is less, light can pass, and other part thickness is larger, light is difficult to penetrate, therefore stitch with rip cutting 2 and the corresponding photoelectric tube of raphe transection 3 can receive light, the photoelectric tube at other position can not receive light.The parameter of the first resistance R1, the second resistance R2 and potentiometer W is rationally set, just can judges the position of rip cutting seam 2 according to the output level of each signal condition unit.In figure 6, when certain photoelectric tube is in joint-cutting place, after it receives light, resistance diminishes, the inverting input level of operational amplifier F is higher than in-phase input end level, operational amplifier F output low level, when photoelectric tube is not in joint-cutting place, its resistance is very large, the inverting input level of operational amplifier F is lower than in-phase input end level, and operational amplifier F exports high level.
If the spacing of photoelectric tube is larger, a photoelectric tube and rip cutting may be only had to stitch 2 relative, if this photoelectric tube is the photoelectric tube of corresponding with blade (being in same plane) just, illustrate that blade and rip cutting are stitched 2 relative, otherwise illustrate that blade deviate from rip cutting seam 2, need to adjust.If the photoelectric tube now receiving light is positioned on the left of the photoelectric tube corresponding with blade, CPU exports signal to the right, the right side of longitudinal seam has been partial to by the blade of the current floating cutter of prompting controller, need the position of adjustable blade left, if the photoelectric tube receiving light is positioned on the right side of the photoelectric tube corresponding with blade, CPU exports signal to the left, and the left side of longitudinal seam has been partial to by the blade of the current floating cutter of prompting controller, needs the position of adjustable blade to the right.
If the spacing of photoelectric tube is less, multiple photoelectric tube and rip cutting may be had to stitch 2 relative, if the photoelectric tube both sides of corresponding with blade (being in same plane) have the photoelectric tube of equal number to receive light, illustrate that blade is relative with the center line that rip cutting stitches 2, do not need to adjust; Otherwise illustrate that blade deviate from the center line of rip cutting seam 2, need to adjust.If the quantity receiving the photoelectric tube of light on the left of now corresponding with blade photoelectric tube is greater than the quantity on right side, illustrate that blade is positioned at rip cutting and stitches on the right side of 2 center lines, need the position of adjustable blade left, CPU exports signal to the right; If the quantity receiving the photoelectric tube of light on the right side of the photoelectric tube corresponding with blade is greater than the quantity in left side, illustrate that blade is positioned at rip cutting and stitches on the left of 2 center lines, need the position of adjustable blade to the right, CPU exports signal to the left.
Obviously, the spacing of photoelectric tube is less, and accuracy of detection is higher, the photoelectric tube close-packed arrays in this device, and the centre distance of adjacent photo pipe is 6mm, and accuracy of detection can meet split requirement completely.
When there is dislocation in the rip cutting seam before and after raphe transection, because the sensing range of optical receiver 17 is wider, cross joint (raphe transection) afterwards rip cutting seam be still within sensing range, therefore floating cutter can automatic tool preset, and without the need to artificial participation, so just substantially increase production efficiency.
The lateral adjustment device be made up of adjusting slider 12, adjusting bolt 13, control hand wheel 14, regulating sleeve 15 is for adjusting the lateral attitude of optical receiver 17, rotate control hand wheel 14, adjusting slider 12 can be made relative to regulating sleeve 15 transverse shifting (adjusting bolt 13 is connected with adjusting slider 12 and regulating sleeve 15 by the screw thread that rotation direction is contrary), so just the photoelectric tube mediated in optical receiver 17 can be adjusted in the plane at blade place, this photoelectric tube is carried out position detection as benchmark.
In Fig. 4-Fig. 6, what the lateral driver device of floating mount adopted is traversing motor M and pinion and rack, corresponding, in Fig. 6, the output port of CPU receives the input end of motor drive module QD, motor drive module QD controls the sense of rotation of traversing motor M according to the cutter head shifted signal that CPU provides, and realizes the automatic tool preset of floating cutter.
