For example, rubber, which is generated electromagnetically by taking advantage of eonsonic effects. Bas vibration behavior of such structures is very much influenced by their shape and the properties of the material used.

For this purpose, it is necessary that even with larger numbers of Schwiiigkopplern the composition of the elastic material is kept exactly constant, Furthermore, materials whose elastic properties are necessary can not change by aging. In addition, wear on the contact surfaces and cracks in the material and on the attachment and force introduction points between the elastic material and the metal during operation over an extended period of time may not result in changes in the oscillation behavior of the coupler. The mentioned requirements are hardly realizable. In addition, mistakes on the Koooler, which can affect his / her behavior, can not be corrected afterwards.

The aim of the invention is at Tereinzelungs- ^and: I'raiis ~ orteinrichtungen with electromagnetically energized. Schwinger to reduce the technological effort, to ensure a high operational reliability and to avoid the disadvantages that result from impairments of function due to manufacturing tolerances, aging and wear.

L * 4 L Ό OU /

Oscillator, aging and wear are not adversely affected and the vibration behavior can be influenced by adjustment possibilities. "

According to the invention this is achieved in that the oscillator for conveying sheet-like objects consists of a lever which is mounted at one end in a pivot point, and two coil springs which are arranged with respect to the fulcrum tangent to the lever and between which it is clamped , The armature of the electromagnet is attached to the lever »At the end opposite the pivot point of the lever: a friction pad is replaceable if required. consolidates, in front of which the sheet-shaped object is guided resiliently perpendicular to the transport direction.

The distance of the coil springs to the pivot point is adjustable and thus the natural frequency of the vibrator adjustable. Instead of Schraubenfedem also part of the adjacent to the pivot rigid bending lever or the entire lever may be formed as a leaf spring, which is clamped variable in their length.

The spring-loaded guide of the sheet-shaped object in front of the friction lining is present when the sheet-like article to be transported is part of a stack having suspension properties. When using the vibrator for transport, individual sheet-shaped objects in the sheet-like object bearing surface at the point at which the friction pad engages, a recess may be present. Ss is also possible to make this surface of a soft elastic material * Unwanted movements due Vibrations or the weight of the sheet-like object can be avoided if it is guided between the stack or the supporting surface and stops or holding elements and thus is displaced only by the friction lining.

The TransOort of the sheet-shaped object comes about so that he in transporting the vibrating friction during transport

Direction by the frictional force resulting from contact is carried along «The oblique division of the lever, the sheet-like object is thereby also by a small amount perpendicular-to 'Iransportrichtung moves» He evades the friction lining spring. If the friction lining swings back again, the leaf-shaped object can not follow fast enough, the contact with the friction lining is lost and it essentially retains its position. Overall, the direction of movement is in the transport direction »

Coil springs 5, lever 12 and armature 3 form a mechanical oscillator whose natural frequency by ".League and moment of inertia of the components lever 12 with various attachments and armature 3 i £ L their arrangement to the fulcrum 4 and the spring constant of the coil springs 5 and their distance from the fulcrum The natural frequency of the system can be adjusted as required by varying a distance a of the helical springs 5 around the fulcrum 4 and thus compensating for manufacturing tolerances instead of the arrangement of lever 12, fulcrum 4 and helical springs 5 described here it is also conceivable to use a leaf spring or a combination of a short clamped leaf spring 15 and a rigid lever 17 (see also Figure 3) .Figure 3, the Einstellmcglichkeit the natural frequency can be adjusted by changing the clamping length of the leaf spring 15 or a To achieve weight Io, the longitudinally displaceable in the longitudinal direction of the lever 17 or the leaf spring 15 a is subordinate.

The size of the natural frequency in comparison with the excitation frequency has a great influence on the function of the oscillator in the transport of sheet-like objects such as labels, documents, banknotes and record carriers. Thus it is necessary for the natural frequency to lie within the excitation frequency large vibration amplitudes and thus to achieve a sufficiently large transport speed. However, if the natural frequency is above the excitation frequency, then the amplitude of vibration collapses very quickly under load and the delivery rate is insufficient, -this initially in resonators of this type and this form of load werden.die natural frequency at zero load increases higher. Sin favorable behavior of the vibrator is achieved when the natural frequency is slightly below the excitation frequency. An increasing load then leads to a larger oscillation amplitude, which effectively counteracts obstacles in the transport of sheet-shaped objects such as cracks, unevenness, kinks *

A friction lining 8, for which rubber was used in the exemplary embodiment, is fastened to the side of the lever 12 (FIG. 1) opposite the sheet-like object 9 by means of a rivet 7. Attachment is also possible in other ways, for example by gluing The friction of the mating between the friction lining and the sheet-like object is substantially greater than that between the sheet-like objects with one another.

The friction lining 8 fastened to the lever 12 performs a movement in the form of a circular arc, as shown in FIG. ¹ , 3... * 0 ¹ QgT ¹ τ ¹ HΉQj ^ X ^ p P * 3 WS "* S ^ ^ IL SG ~ "^ * ¹ ^ CIS SJP" ~ ^ S ^ ^ jT * γίοτ ^^ ρη ^ S'CüT ' » D ^ r ^ d V ¹ -! λ V ·. j ^ *] "I ^ * 7" Ij.

Available forces and the effect of mass and air resistance of the sheet-shaped object 9 of the movement of the friction lining 8 does not follow. The contact between the friction lining 8 and sheet-like object 9 is interrupted and the sheet-like object remains practically in place when the lever 12 swings back provided in Figure 2, which prevent with the help of low Reibkrafte the movement of the sheet-shaped objects. The frictional force between the friction lining and the sheet-like article 9 must be substantially greater than that between the sheet-like article 9 and the stop 13 or the holding elements 14. "This can also be achieved if 14 friction rollers are used instead of the stops 13 or the holding elements. which are smooth in the transport direction of the sheet-shaped article 9, but contrary to the direction of transport »

Overall, the sheet-like object 9 is moved in the swinging of the lever 12 in the direction of transport indicated in Figure 2 «

Between the mechanical oscillator and machine frame springs 6 are attached as shown in Figure T * They are to prevent the transition of vibrational energy to the Ziaschinengestell * Moreover, it is achieved by these springs 6, that the pressing force of Reibbelases 3 to the b-lattfcrmigen objects 9-only slightly changes , if the stack is positioned inaccurately on the oscillator, because the oscillator can dodge.
