(54) METHOD FOR TRANSPORTING FERROMAGNETIC MATERIALS

I

Invented refers to the transport technique and can be used to transport small-sized parts, as well as loose ferromagnetic materials, such as fobed chips.

The known method is transported by non-conductive liquids and materials by means of a traveling magnetic field and direct current, which generates moving waves Z on the surface of an electrically conducting fluid.

The disadvantage of the method is the electrolyte energy increasing costs for overcoming the sliding friction with the material on the gutter walls. In addition, the implementation of the method requires additional material costs, for example, for a hydraulic system.

The closest technical solution to the present invention is a method for moving ferromagnetic materials, which consists in the movement of materials by a running magnetic field created by alternate switching on of electromashites 2.

However, the existing transport method does not allow the orientation of materials (bodies.

details) in the process of transportation and requires increased electrical energy costs for overcoming the sliding friction between the transported body and the shell.

The purpose of the invention is to reduce energy costs by eliminating sliding friction using the kinetic energy of the transported material and ensuring reorientation of the material during transportation without using additional means.

This goal is achieved in that the electromagnet switches in pairs through one with opposite polarity in each pair, then disconnect one electrical socket in each pair from the side opposite to the direction of movement of the material, and include previously not included electromagnet, forming regular pairs with opposite polarity.

Moreover, the previously non-included electromagnets include when the transported material reaches the maximum value of the kinetic energy. 3 In addition, the nearest electromagnets in the adjacent pairs include with the same polarity. Fig, 1 shows the placement of the parts with the included electromagnets; in fig. 2 same, with the electromagnet off in each pair from the side opposite to the movement of the part; in fig. 3 - the same, when enabled; in fig. 4 - placement of bulk materials with electromagnet on; in fig. 5 - the same, with the electromagnet off in each pair from the side opposite to the bulk material; in fig. 6 - the same, with the electromagnet previously turned off. B) tsvami N and S denotes the pole position of the included magnets. The method of transporting ferromagnetic parts is as follows. When electromagnets 1 and 2 are connected with opposite polarity, the transported parts 3, supplied to the non-magnetic chute 4, are oriented along its upper wall, occupying a certain position (Fig. 1). Then, when electromagnets 1 are disconnected, part 3, held by electromagnets 2, under the effect of The seals make a tiny-figurative movement in the direction of the disconnected electromagnets 5. When the kinetic energy of the transported parts reaches its maximum value (Fig. 2), electromagnets with polarity opposite to that of ektromagn there 2. 3 Details of inertia extend the lower position and under the action of electromagnets Ack are pulled into the position poTsazanioe FIG. 3. Further transportation of parts from the position (Fig. 3) is carried out similarly. The magnitude of the magnetic field strength and the distance between the electromagnets is selected depending on the mass and dimensions of the parts being transported. Transportation of ferromagnetic materials using the proposed method is determined as follows. When electromagnets 1 and 2 with opposite polarity are turned on, the transportable bulk ferromagnetic material b (for example, crushed chips) fed into the non-magnetic chute 4 is oriented along the magnetic forces; the electromotive headlines of the 1 and 2 headings have shown the position shown in FIG. 4. Further transportation of material 6 from the position shown in FIG. 4, is carried out similarly to the transportation of the part. Thus, the use of the proposed method makes it possible to combine operative transportation of parts with their orientation and fixation in the desired position in the process of performing technological operations without using any additional means. In addition, a small-shaped walking movement of parts along a transport chute, in comparison with known methods, eliminates sliding friction of parts on the gutter walls and reduces the magnetic field strength by using the kinetic energy of the parts being transported and, consequently, reducing energy costs for transporting parts with the same parameters. The use of the proposed method for transporting bulk ferromagnetic materials makes it possible to meter the material being transported approximately equal in mass to the portions and regulate the portion size by varying the magnetic field strength, and the number of portions delivered per unit of time, by changing the speed of its movement. In addition, the proposed method due to the action of centrifugal force arising in the process of matiform movement of the transported material, such as crushed chips, effectively separates non-ferromagnetic impurities, such as coolant and non-ferrous metal chips.
