In Fig. 14 it is shown that the variable impedance 126 is connected in series with the vertically arranged electromagnet 6. Adjusting the impedance 126 the phase relationship between current and voltage at the magnet 6 varies. As a result, the phase relationship in the operation of the vertically arranged electromagnet with respect to the horizontally arranged electromagnets is 7, 8 changes. When adding the impedance 126, it may also be necessary to vary the gate voltage for the silicon rectifier 120 in order to achieve a desired deflection or a desired stroke of the conveyor obtained, which can be a straight line of adjustable length and inclination or an elliptical trajectory of adjustable size, eccentricity and inclination can act. The control of the impedance 126 therefore changes the magnitude of the applied voltage. Therefore An adjustment via the variable resistor 124 may be necessary in order to correct the voltage applied to the silicon rectifier 120. The voltage applied to the vertically arranged electromagnet 6 can be returned to their original size so that the desired one exerted on the conveyor housing

Funding movement is achieved, or so that one in one achieved optimal conveying conditions for a specific application.

The oscillation or vibration amplitude of the independently controlled horizontally and vertically arranged shaker can be adjusted by changing the resistance 124, whereby a regulation of the conveying angle of the vibratory conveyor is also possible at any moment in order to ensure the effective conveying movement to achieve the respective funding conditions.

Adjusting the impedance 126 affects the phase relationship between current and voltage across the electromagnet 6, while the phase relationship of current and voltage to the electromagnets 7 and 8 remains constant. Ss This results in a change in the hoop relationship between the vertical vibration direction and the horizontal vibration direction in the operational area, which means different resulting · oscillation paths of the conveyor housing can be achieved, so that in any Application case the optimal delivery rate can be achieved for a given application.

notices that there are different types of rules applicable here there to add the desired vibration to the case mass cause. These types of rules all serve to achieve one of the main objectives of the invention, that therein exists, effectively and selectively, the phase relationship of the currents through the vertical and horizontal magnets to change in order to achieve a change in the desired path of the oscillation movement of the conveyor housing. For example, one can use the entire control loop for the silicon leveler for both the horizontal and the also omit the vertical shaker and still receive an alternating current at the shaker · With this a two-mass oscillating system for alternating current is also implemented. It is now only necessary that Regulate the respective sizes of the individual types of vibration see below. This can be done by a shunt control with variable, the solenoid coil, as shown in Hg. 16, control transformer connected in parallel be realized. If a pulsating DC voltage is used, a variable resistance can be used connected in parallel to the respective rectifiers of the vertical and horizontal control equipment.

is connected in series with the vertical shaker.

Furthermore, for example, either the horizontal or one of the control loops for the silicon rectifier can be omitted in the case of the vertical shaker. The resulting excitation current is then rectified for one of the two electromagnetic coils of the shaker, while the other coil of the shaker generates the desired movement. The regulation of the amplitude of the silicon rectifier is only intended for one type of oscillation, while an 'alternating current shunt control, as described above, is provided for the second mode of oscillation. This scheme works with the impedance 126 for the regulation of the operated phase either in the vertical or in the horizontal Type of vibration together.

From the preceding part of the description it can be seen that the invention comprises a regulation or control of the oscillating movement of a two-mass Sohwingsystem in which various vibration exciters are provided, which cooperate with a flexible coupling.

- Can change the delivery rate / by either the vertical or horizontal component or by changing both components and their phase relationship at the same time. Such an attitude of the Vibration components create an alternation of the the resulting oscillating motion transmitted to the conveyor housing. The resulting swinging motion can be like this be selected so that an optimal delivery rate is achieved with delivery-level delivery conditions »This is Regardless of whether the optimal resulting movement runs along a straight line, variable length and inclination with respect to the conveyor trough or track, or whether there is an elliptical trajectory of adjustable size, eccentricity and inclination.
