Description

one

This invention relates to staphycosis.

Conveyor drives are known, for example, a flow line, in which for the reception of translational motion an electric source of movement is used, for example, a linear electric motor. These electric motors consist of a primary part, equipped with a coil with windings, and a short-circuited, rhetorical part, of which one part is fixed and the other is not moved by the motive force due to the power impulses emanating from the nervous part.

With the help of linear electric motor, the vehicle is driven. For this purpose, they are supplied with a nervous part that moves along a guide formed by a fixed secondary part. When using such a drive, a transport device must be equipped with an aggregate that generates electrical energy, and it becomes difficult to supply electric current to the moving windings.

For moving vehicles over a short distance, a linear electric motor is used, acting on the reverse working liner. To do this, coils with windings that are located symmetrically relative to each other are fixed as the terminal part in the zone of movement. In the air gap between these skins, in the event of their excitation, the secondary part is moved, which is made in the form of a loses body, with one of its ends protruding over the roller table so that it can be suspended by a trailing rope. The coils for accelerating the secondary section are connected to a temporary current network, and for braking it to a direct current network. With

this tends to quickly enough to inform the secondary section of a high speed or to slow it down on a certain part of the path. However, when using this device it is not possible to stop several parts after

the passage of the defined portion of louty in predetermined positions.

The aim of the invention is to keep the satellites independent of each other, controlled directions and independent, equal amount of movement economically and without negative impact on the environment.

For this, at each addressee, at least, one primary part of the linearity of the engine and a combination of switches acting on the primary parts of the engine and on the satellites are installed.

The primary parts of the linear motor are installed inside the addressees, one at a time,

and groups.

The primary parts of a linear electric motor arranged in groups are arranged in parallel or a boat with an angle to each other or parallel and a boat with an angle.

In this case, two switches are located before and two after the primary parts of the linear motor.

FIG. 1 shows a part of the transport line with possible arrangements for the arrangement of linear electric motors with a satellite used to install and fix the workpiece therein; in fig. 2 - a rough installation of a satellite in a predetermined position with a crowbar; on the switches located on the surface of the transport device (section along A - A on the Fig. 1); pas figs. 3-precise satellite installation.

The transport line consists of separate sections 1-5, of which the latter is made in the form of a specific section (intersection. Each of these sections also has level surfaces 6 and rolling surfaces 7 for satellites to be transported, as well as deeply located surfaces 9 for fastening the primary parts 10-18 of the linear motors used.

Linear motors are known, so their primary parts 10-18 in FIG. Figures 1 and 2 are indicative of a linp. Pa figs. 3 shows their constituent parts, namely, the main body 1-8, the parts 19 of which, having a jagged shape, form magnetic poles, between which winding 20 is located.

On the underside of each satellite 8, at least one secondary part 21 is attached, which interacts with various nervous parts 10-18 according to the principle of action of a linear electric motor, namely those that fall within its field of action.

Each secondary part 21 consists of at least one plate 22 made of a material with high electrical conductivity, a plate 23 made of a material with high magnetic conductivity for magnetic closure. Both plates for starting and braking of the lower parts are made longer with each of the primary parts 10-IS.

Pa drawings show some possible arrangements for the placement of primary parts. These options can be reconciled with the real conditions, but for this it is necessary that the satellites 8 move irreproachably. Since the satellites are expedient to perform the same, the masses being moved by them are under the strong action of these satellites, they mainly determine the position of the center of gravity of the inner tube 8. A possible extremely shifted position of the center of gravity may require that in order to reduce the resulting torques , in one direction, respectively, there were two primary parts parallel to the middle, such as I, 12, 14, 15, and 16, 18, and in the middle in the other direction, one primary part, 10, 17, and 13, respectively. Section 5 ne esecheni should be sufficient for both directions and therefore both provided with two parallel primary portions 16, 18 and one average initial part 17. -When it is necessary that one of the existing primary sections 10-18

has always been covered by the secondary part 21. To do this, a group of secondary parts 21 is provided on the lower side of each satellite 8 (Fig. 3).

FIG. 2 shows how satellite 8 through

the primary parts 16 and 18 fall into the intersection section 5. On the lower side of the satellite, the secondary section 21 is located. On the rolling surface of the intersection section 5, switches Si-54 are installed.

FIG. 3 above the primary part 18, the secondary part 21 is partially depicted. In the plate 22 of this part of a material with high electrical conductivity, two strips 24 of material with high magnetic conductivity are laid. Both strips are located symmetrically to the middle of the plate 22. The width of each of these strips is larger than the width of the grooves between the parts 19. The distance between the middle of the strips 24 corresponds to the distance between the middle of two opposite poles of the primary parts 10-18.

In the quiescent state, satellite 8 is in the middle position in section 4 and both of its parallel secondary parts are located

in the middle over the primary parts 14 and il5. In this position, satellite 8 is displaced when the windings 20 of the primary parts 14 and 15 are excited as a result of their connection to the AC network. This is done

using a control device that contains a motion program. When the windings 20 are energized, each primary part 14 and 15 produces a moving electromagnetic field, which is characterized by the distribution of the poles of the primary parts 10-18 and has a synchronous speed corresponding to the frequency of the electric current in the network. Due to this, eddy currents are induced in the respective secondary parts 21 of the satellite 8, which, in accordance with the known physical regularity, cause the secondary parts 21 to move and, thus, the satellite 8 moves in the direction of the moving electromagnetic field.

In this case, the braking caused by the friction forces acting on the satellite 8 prevents the secondary parts 21 from receiving the speed of the moving electromagnetic field. To guarantee the case

The speed of the satellite 8 must not exceed a certain value. Thus, the primary parts 10-18, when excited, are driven by pulses. The duration of the pulses required

to achieve the desired speed depends

from the masses that need to be transported, the lengths oTpesKOiB of displacement, as well as the energy loss that may occur during this displacement.

In order to reduce the loosened effects, it is necessary to equip the base with 7-pump surfaces for satellites 8 as well as guide surfaces 6. It is most appropriate to move satellites 8 on an airfoil. The duration of the impulses, necessary for the prevention of movement, can be determined by means of a computational mask and then transmitted to the control device. Thus, if satellite i8 is to move at a certain speed from section 4 to section 5, the primary parts 14 and 15 are connected to the calculated time IK of the inepeMOHiioro current network. Having received the acceleration due to the appearing force impulse, the Satellite 8 intercepts through the primary parts 16, 17, 18 of the intersection section 5.

Switches from 5 to S serve to bring the satellite: 8 over. Some area, such as part 5, to the state. Approaching satellite: 8 first passes over both switches Si and Sy, when switch 5z operates, primary parts 16 and 18 are actuated to move the satellite -8 in the opposite direction, due to which secondary parts 21 are countercurrently braked. The duration of the action of this counter-force can be calculated using a computational mask in order to exclude movement in the direction opposite to the original movement. If satellite 8 reaches now switch 5-. then the switches Si and S4 are actuated at the same time, and the AC winding of the primary parts 14, 15 is connected to the DC source. Using the obtained fixed magnetic field, the satellite is affected by a non-directional inhibitory effect. If this process is inhibited. the satellite 8 does not stop, then after the Si switch is released, the primary parts 14, 15 are reconnected to the AC network so that a moving magnetic field is formed, the direction of which is opposite to the direction of movement of the satellite 8. This countercurrent is produced until the satellite 8 It will not turn on both switches Si and S4 again, which will lead to the inclusion of DC braking.

Power pulses with alternating direction, the reciprocating movement of the satellite 8 and, eventually, its coarse stop in the boundaries that are defined by the switches Si and S. The stationary magnetic field, resulting from the actual direct current, takes away from Ontnika 8 energy until it reaches a quiescent state. In order to achieve an exact average position, stripes 24 are used, with the help of which an accurate satellite stop is achieved.

8 in section 5. The selected width and placement of these strips 24 determine that they stop, respectively, over the two different poles of the primary parts. These poles are formed by the excitation of the winding 20 with a constant current. The magnetic field that occurs in this case tends to be in such a state when its lines of force have a minimum length, i.e. when these lines of force enter a plate

23 not through the plate 22, but through the strips 24, as a result of which a closed magnetic magnetic circuit is formed. This arrangement of lines of force contributes to the development of forces that cause strips 24 to move in more

favorable, in terms of magnetic field lines, position. Consistent with this desire, the expedient placement of the strips 24 in the secondary part 21, and thus also on satellite 8, leads to an exact stopping of the satellite in the Ho-XQ position.
