Иообретение относитс к области автомй тической загрузки технологического оборудовани и может быть использовано дл активного контрол и сортировки различных по форме и размерам асимметричных деталей. The invention relates to the field of automatic loading of technological equipment and can be used to actively control and sort various asymmetric parts of various shapes and sizes.

Известны способы фиентации немагнитны токотфовод ших деталей с различной эквивалентной проводимостью коннов под воздействием электродинамических сип, возникающих при взаимодействии магнитных полей ин дуцированных в детали токов с основным магнитным полем.Known methods of fientation are non-magnetic to the current-to-water parts with different equivalent conductivities of horses under the influence of electrodynamic sip, arising from the interaction of magnetic fields of currents induced in the part with the main magnetic field.

Предложенный способ отличаетс от известных тем, что на индуцируемый в детали контур тока воздействуют магнитными дополнительньис контуров токов, индуцируемых тем же магнитным полем и расположенных симметрично и параллельно плоскости контура индуцируемого в детали тока с частичным перекрытием его, по крайней мере , с одного конца детали.The proposed method differs from those known in that the current circuit induced in the part is affected by magnetic additional current circuits induced by the same magnetic field and arranged symmetrically and parallel to the plane of the current induced in the part with partial overlap of it at least at one end of the part.

Это позвол ет уменьшить энергозатраты и увеличить чувствительность процесса.This reduces power consumption and increases the sensitivity of the process.

На фиг. 1 показано возникновение несимметричности силового воздействи дл асимметричной детали; на фиг. 2 - устройство дл реализации предложенного способа.FIG. Figure 1 shows the occurrence of a force asymmetry for an asymmetric part; in fig. 2 - a device for implementing the proposed method.

Биметаллическую пластинчатую деталь 1 помещают в переменное магнитное поле. По противоположным асимметричным концам детали помещают короткозамкнутые витк -контуры 2-5 перпендикул рно вект1 ру индукции и на одинаковом рассто нии от соответствующих асимметричных концов детали. Как в контурах 2-5, так и в детали 1 навод тс индукционые токи 1 Д,, ij, Сц и Lg примерно о ииаковой фазы.Bimetallic plate part 1 is placed in an alternating magnetic field. At the opposite, asymmetrical ends of the part, short-circuited loops 2-5 are placed perpendicular to the induction vector and at the same distance from the corresponding asymmetric ends of the part. Both in circuits 2–5 and in part 1, induction currents 1 A ,, ij, Sc and Lg induce approximately the ionic phase.

Claims

It is known that equally directed currents are attracted, while oppositely directed currents are repelled. When the phase angle coincides, all currents are directed to the same direction at any time. With a small phase mismatch, the mean values of the currents lii-D-Sitii MLj averaged over any half-period coincide in direction. Therefore, currents Ts1-5 always attract one to the other. And since the short-circuited contours 2-5 are rigidly fixed, only a part can mix. Due to the different conductivity of the material of the part 1, the current loop L is always a few times confused towards the end of the part with the best conductivity, and the force interaction between the contours is inversely proportional to the square of the distance. Therefore, part 1 at the position shown in FIG. 1, is more strongly attracted to contours 2 and 5 and, with a corresponding magnitude, the field quickly moves towards these contours. Due to the gained speed, the part passes the equilibrium position and leaves the magnetic field. In the device for carrying out the proposed method, a magnetic field is obtained between the flat poles 6 and 7 of the electromagnet and the closed contours 2-5 of the magnetic field in the grooves of the magnetic core. This will significantly reduce the magnitude of the air gap and reduce energy loss. In the case of a plate-like (thin) part, short-circuited turns can be placed only on one of the flat poles. For relatively thick parts, short-circuited coils, it is more expedient to place an electromagnet on an obop ionium. The field with radial symmetry has the most universalism, which can (roughly) be made with. Cylindrical with symmetrically stimulated kg1Gotko.closed loops, rasangshzheinymi). the limiting circumference of the poles is 6 to 7. Such a floor can be obtained in zazorg1X O-shaped, f-shaped and others in the form of electromagnets. The invention of the method of orientation of non-magnetic conductive parts with different equivalent conductivity of the ends under the influence of electrodynamic forces arising from the interaction of magnetic fields induced by parts of the currents with the main magnetic field, so that, in order to reduce energy consumption and an increase in the sensitivity of the process, the current contour induced in the detail is affected by the magnetic fields of the additional current circuits induced by the same magnetic field and located symmetrically but also parallel to the plane of the contour of the current induced in the part with its partial overlap, at least from the end of the part.
