Brief description of the drawings
Fig. 1 is automatic deviation rectifying device application schematic diagram.
Embodiment
The utility model is described in further detail below by embodiment combination accompanying drawing.
This example provides a kind of automatic deviation rectifying device of sheet material, by designing photoelectricity electric eye automatic tracing sheet material edge, realizes
The automation adjustment of photoelectricity electric eye, saves manpower, and the dynamic correcting of sheet material, prevents sheet material from shifting.
Specifically, the application schematic diagram of the automatic deviation rectifying device of this example is as shown in figure 1, automatic deviation rectifying device includes reflector
1st, photoelectricity electric eye 2, governor motion 3, controller 4 and drive mechanism 5, wherein, reflector 1 and photoelectricity electric eye 2 are respectively arranged at plate
The heteropleural of material 6, and, at least part of reflector 1 is exposed on the outside of the edge of sheet material 6, and photoelectricity electric eye 2 receives reflector exposed parts
Reflected light and reflected light be converted into electric signal sent to controller 4, in this example, reflector 1 is arranged at the lower section of sheet material 6, light
Electric eye 2 is arranged at the top of sheet material 6；The output end of governor motion 3 is connected to photoelectricity electric eye 2, and input is connected to controller 4.
By above-mentioned design, before sheet material 6 moves, photoelectricity electric eye 2 can be controlled to be automatically adjusted to the edge of sheet material 6,
Adjustment is participated in without artificial, the preferred scheme of this example is：Photoelectricity electric eye 2 first receives 100% reflected light of reflector 1, then
100% reflected light is converted into electric signal, is such as converted into 12V voltage signal, then the half of reflector 1 is exposed into plate
On the outside of the edge of material 6, half is blocked by sheet material 6, using the relative position of reflector 1 and sheet material 6 as reference position, and by photoelectricity
Electric eye 2 is in the electric signal that is fed back during the reference position as reference electrical signal, i.e. reference voltage signal is 6V, controller 4
Controlling to adjust mechanism 3 according to the instruction for finding the edge of sheet material 6 drives photoelectricity electric eye 2 to move, and and if only if, and photoelectricity electric eye 2 receives
When reflected light is 50%, photoelectricity electric eye 2 is in the edge of sheet material 6, at this moment, the voltage that the photoelectricity electric eye 2 that controller 4 receives feeds back
Signal 6V, now, controller 4 control to adjust mechanism 3 and photoelectricity electric eye 2 are positioned at into the edge of sheet material 6, so as to reach photoelectricity electric eye
The purpose of 2 adjust automaticallies.
It should be noted that the conversion of the optical signal of this example to electric signal belongs to existing photoelectric conversion technique, it is ability
Known to field technique personnel, controller 4 is built-in with control circuit, to realize the specific control to governor motion 3, such as passes through control
Circuit processed sends high level signal, or low level signal to governor motion 3, and governor motion 3 is according to high level signal or low level
Signal enabling works.Such as, the governor motion 3 of this example is servo motion module, specially a kind of high-precision screw mandrel servo motion mould
Group, photoelectricity electric eye 2 are fixed on the moved end of servo motion module.
During sheet material 6 moves, the bin needed for sheet material 6 includes winder and unreeling machine, enters by taking the winding of sheet material 6 as an example
The process of row explanation dynamic correcting：Because before the movement of sheet material 6, controller 4 has stored reference electrical signal, with reference to electricity
Exemplified by press signal be 6V, if because the interference of outside causes sheet material 6 to wander off, it is assumed that sheet material 6 is towards the exposed lateral deviation of reflector 1
Move, then the shading amount of reflector 1 increases, and accordingly, the reflection light quantity for the reflector 1 that photoelectricity electric eye 2 receives reduces, photoelectricity electric eye 2
The voltage signal of feedback is less than 6V, and controller 4 calculates the exhausted of sheet material 6 according to the feedback voltage signal and reference voltage signal of reception
To offset, then, controller 4 sends instruction control drive mechanism 5 and moves adjustment winder 7 by absolute offset values, until receiving
The edge of the sheet material 6 of volume keeps neat, and during being rectified a deviation in sheet material 6, controller 4 controls to adjust mechanism 3 and drives photoelectricity
Electric eye 2 follows the trail of the reflected light of reflector 1, is not in the situation that photoelectricity electric eye 2 is all blocked by sheet material 6 therefore, accordingly,
Also be not in the phenomenon of hysteresis correction.
It should be noted that the detailed process that controller 4 calculates absolute offset values is：First calculate the actual survey of photoelectricity electric eye
The error amount of voltage signal and reference voltage signal is measured, is formed further according to the helical pitch parameter of the error amount and servo motion module
Coefficient make product, you can calculate absolute offset values；Certainly, the calculation procedure that specific calculating process is related to is equal
It is existing calculation procedure, such as the program of calculation error value, exactly calculates the absolute difference of two values, the calculation procedure is
Well-known to those skilled in the art, therefore, the controller 4 of this example is in function in realizing certain, even if being related to computer
Program, it is also existing computer program, is not related to the improvement of computer program.
Further, when drive mechanism 5 controls winder 7 to be moved according to absolute offset values, in order to obtain winder 7 in time
Mobile displacement whether reach absolute offset values, the automatic deviation rectifying device of this example also includes displacement transducer, displacement transducer
Preferably mechanical displacement sensor, the moved end of displacement transducer are connected with the winder 7 of sheet material 6, the fixed end of displacement transducer
It is connected with drive mechanism, the actual mobile displacement of the winder 7 of measurement is fed back to controller 4, controller 4 by displacement transducer
It can determine whether winder 7 is moved by absolute offset values according to the value of feedback of acquisition, if it is not, controller 4 continues control driving
Mechanism 5 drives winder 7 to move, and to realize that winder 7 is accurately adjusted by absolute offset values, further, drive mechanism 5 includes electricity
Hydraulic servo and hydraulic cylinder；The input of electrohydraulic servo valve is connected with controller 4, and output end and the hydraulic cylinder of electrohydraulic servo valve connect
Connect, the fixed seat of hydraulic cylinder is connected with the fixed end of displacement transducer, and electrohydraulic servo valve is under the control of controller 4, band hydrodynamic pressure
Cylinder driving winder 7 coordinates the correction process of displacement transducer completion sheet material 6.
Use above specific case is illustrated to the utility model, is only intended to help and is understood the utility model, and
Not limiting the utility model.For the utility model person of ordinary skill in the field, according to think of of the present utility model
Think, some simple deductions, deformation can also be made or replaced.
