Abstract
A method of oriented feeding of nonmagnetic current-conducting components is proposed, wherein an alternating magnetic field is set up, whose induction vector is normal to the desired direction of feeding. Components are introduced into this field, one by one, and at least one closed current-conducting loop is secured in the magnetic field so that its plane is normal to the induction vector of the field and offset with respect to the geometrical center of the component introduced into the field in the direction of feeding. Oriented feeding is effected under the action of electrodynamic forces induced in the alternating magnetic field as a result of the interaction of the overlapping current circuits induced by the magnetic field in the components and in the current-conducting closed loop. The device for carrying out the proposed method comprises a source of an alternating magnetic field and a sectional plate arranged in the working area of this field, each plate section including an electric coil. The device is also provided with a control panel including a set of contacts corresponding in number to and arranged in the same manner as the plate sections. Each coil has one of its terminals connected to a respective control panel contact, and the other coil terminal is grounded.
