Such oscillatory arrangements or vibrating tables are set in oscillation by vibration generators or vibratory drives. To enable the swing, the vibrating tables or racks are usually placed or stored on elastic spring elements.

The respective function is influenced by various parameters, in particular decisively by the direction of oscillation, the form of oscillation and the oscillation speed. There are several ways to influence these parameters. Known is the rotation of imbalances of the vibrator from a stable state, which results from a self-synchronization. A mechanical adjustment by means of drag balancing or coupling of the imbalances by transmission is also possible.

In the figures, the same reference numerals are used for the same and similar components, and the corresponding or similar functions, properties and advantages arise, even if a repeated description is omitted.

Fig. 1 shows a schematic side view of a proposed oscillating arrangement 1, which preferably carries or forms a proposed vibrating table 2.

The vibrating arrangement 1 or the vibrating table 2 serves in particular for compacting bulk material 3, as in FIG Fig. 1 indicated schematically. The bulk material 3 may be, for example, sand, concrete or the like.

Depending on the intended use, the vibrating arrangement 1 or the vibrating table 2 can have a vibrating plate 4 with or without laterally upstanding edges and / or other possibilities for fixing or fastening goods to be vibrated, for example, molds filled with bulk material or the like , In the illustrated example, the vibrating plate 4 is shown with a laterally upstanding edge in a schematic section to show by way of example the bulk material 3 as a vibrating good.

The oscillating arrangement 1 preferably has a frame 5 with a plurality of vibration generators 6 for generating a schematically indicated oscillatory movement 13.

The vibrating arrangement 1 or the vibrating table 2 or the frame 5 is preferably mounted swinging by means of spring elements 7, as in Fig. 1 indicated schematically. As spring elements 7 in particular correspondingly formed springs, preferably coil springs used.

The spring elements 7 carry the frame 5 in particular on the underside and / or preferably extend vertically. However, other spring arrangements are possible.

Fig. 2 shows a perspective view of the proposed oscillating arrangement 1 without shaker or table top. 4

The frame 5 is preferably at least substantially rectangular, cuboidal or cube-shaped, wherein the vibration generator 6 are preferably arranged on the outside of the frame 5 on the side surfaces 11 of the frame 5 or introduced.

The frame 5 preferably has an at least substantially rectangular or square outer contour in horizontal section, in particular in a section parallel to its upper side 12 or to the table top 4 or under the table top 4, on.

The upper side 12 of the frame 5 may possibly also form the table top 4.

Preferably, the frame 5 is formed at least substantially frame-like and / or provided with a central recess or opening. If desired, bulk material 3 to be compacted or other goods to be vibrated may also be received by the frame 5 or in its recess.

The oscillating arrangement 1 has a plurality of, preferably four, vibration generators 6. However, it is also possible to provide more vibration generators 6; for example, the vibration arrangement 1 can also have six or eight vibration generators 6. For example, two vibration generators 6 can then be arranged on one side of the frame 5 together or next to each other and aligned as required parallel or coaxial or obliquely or perpendicular to each other.

Preferably, the vibration generator 6 are arranged in pairs on opposite sides in particular of the frame 5 and / or aligned in parallel.

The orientation generally relates in particular to the axes of rotation of the vibration generator 6 or imbalances.

In the first embodiment, the vibration generators 6 are preferably at least substantially horizontal or horizontally aligned or arranged.

Preferably, two vibration generators 6 are aligned in a first, in particular horizontal, direction and two other vibration generators 6 in another, in particular perpendicular, second, in particular horizontal, direction. This can be particularly preferably realized by the outside arrangement on the frame 5.

The vibration generator 6 preferably have asynchronous or synchronous motors. Alternatively, the vibration generator 6 may also comprise or be formed by magnetic drives.

The vibration generator 6 preferably have unbalance motors or are formed thereby. The vibration generators 6 are particularly preferably unbalanced motors, that is to say electric motors with driven shafts which carry imbalances.

More preferably, said directions or orientations of the vibrators 6 refer to the axis position of shafts that rotate and carry imbalances for generating vibration.

Alternatively, unbalance exciter cells can be used, which are driven accordingly.

Next come also magnetic drives or other linear drives into consideration, which can be used as a vibrator 6. The linear movements then preferably run in the direction of the preferred orientation or arrangement of the respective vibration generator 6.

The vibration generator 6 or drives can optionally be rigidly or elastically attached to the frame 5. If necessary, the coupling can be performed differently hard in different directions, for example by using a leaf spring. In the longitudinal direction of the leaf spring is then the Vibration generator 6 or drive with the frame 5 practically rigidly connected. In the normal direction of the wide side of the leaf spring, the coupling is soft. In the direction of the narrow side of the leaf spring, the coupling is hard and the drive and the frame 5 oscillate with the same amplitude.

The control or regulation of the vibration generator 6 is preferably carried out electronically.

Magnetic drives or other linear vibration generator 6 can be controlled or regulated accordingly.

Preferably, the vibration generator 6 can be controlled or regulated in such a way that the vibration arrangement 1 or the vibration fish 2 can be moved in all three spatial directions, that is to say a vibration movement 13 can be generated in all three spatial directions.

Alternatively or additionally, a rotational oscillation of the oscillating arrangement 1 or of the vibrating table 2 is possible, in particular alternatively around a vertical or horizontal axis of rotation or about an arbitrary spatial axis. Preferably, therefore, the vibrating arrangement 1 or the vibrating table 2 can also move rotationally about all three spatial axes or oscillate about them.

The relative position of the imbalances of the vibration generators 6 or the relative oscillation of the vibration generators 6 is set and controlled or regulated in such a way that the desired vibration behavior or the desired vibration movement 13 is achieved.

For example, when the oscillator 6 is switched on and / or switched off, it initially works in such a way against one another that at least essentially no oscillation occurs, in particular that the oscillation amplitudes of the different oscillator 6 compensate each other, preferably in pairs. Thus, when starting up and / or shutting down an undesired oscillation when driving through natural resonances of the oscillating arrangement 1 or the vibrating table 2 can be avoided.

Only when reaching or exceeding a desired speed, in particular when reaching the nominal or working speed, then the unbalance in such a way adjusted relative to each other that the desired swinging motion 13 is generated.

The relative position of the imbalances can be selectively controlled or regulated. For example, a control or regulation of the relative position of the imbalances via a corresponding control of the vibration generator 6 and of motors of the vibration generator 6 take place.

Alternatively or additionally, a determination of the (relative and / or absolute) position of the imbalances can also be made by means of sensors, not shown.

Thus, a swinging movement 13 of the oscillating arrangement 1 or the vibrating table 2 can be determined or controlled or regulated.

Alternatively or additionally, a detection and optionally control or regulation of the oscillatory movement 13 of the oscillating arrangement 1 or the vibrating table 2 by means of vibration sensors not shown and / or by non-contact measurement of the position of the vibration assembly 1 and the vibrating table 2 and the table top 4 and / or by detecting the load or movement of the spring elements 7 are determined.

Particularly preferably, the oscillating movement 13 of the oscillating arrangement 1 or of the vibrating table 2 can be changed during operation.

Preferably, the vibration generator 6 are provided with mounting plates 8 and connected via this with the frame 5 and attached to the side surfaces 11. However, other constructive solutions are possible.

Fig. 3 shows in a similar perspective view a preferred, optional skew of one or more vibrators 6th

Particularly preferably, one, several or all vibration generator 6 are pivotally mounted or held on the frame 5 and fixed in its pivotal position, tiltable in the representation example to the horizontal or obliquely adjustable. In this way, an optimal adjustment of the oscillatory movement 13 can take place. Particularly preferably, the vibration generators 6 can be set in pairs or on opposite sides in the same direction or opposite obliquely.

Particularly preferably, the vibration generators 6 are alternately inclined in the opposite direction around the circumference of the frame 5 and / or in each case by the same angular amount.

Particularly preferably, the frame 5 and / or one of the respective vibration generator 6 associated mounting plate 8 curved slots 9 for pivotal adjustment of the respective vibration generator 6. The slots 9 are penetrated by preferably corresponding screws 10, in particular so that the respective vibration generator 6 with its mounting plate 8 fixed - so rotatably - on the frame 5 and its side surface 11 is set. This allows a simple construction and a simple adjustment. However, other constructive solutions are possible.

According to the proposal, an independent inclination of the vibration generator 6 is generally possible. In particular, therefore, only a single vibration generator 6 can be set obliquely independently of the other vibration generators 6 or tilted at a different angle.

Hereinafter, further embodiments of the proposed oscillating arrangement 1 will be explained in more detail with reference to the further figures, the previous statements and explanations in particular corresponding or supplementary apply, even if a description thereof is omitted.

Fig. 4 shows in a to Fig. 2 corresponding perspective view of a proposed oscillating arrangement 1 according to a second embodiment. In the second embodiment, two vibration generators 6 arranged on opposite sides are preferably vertical, that is to say they are oriented at least substantially vertically. The second direction is therefore preferably vertical here. Otherwise, the previous statements and explanations to the first embodiment preferably apply correspondingly or in addition.

Fig. 5 shows a proposed oscillating arrangement 1 according to a third embodiment. Here, the vibration generators 6 are at least substantially parallel and / or in pairs at least substantially in a row or coaxially arranged. This makes it possible, in particular, to switch over from purely rotary to translatory oscillatory motion of the oscillating arrangement 1 or of the vibrating table 2 and vice versa.

In the third embodiment, the vibration generators 6 are preferably arranged or fastened via their attachment plates 8 on an upper side 12 of the oscillating arrangement 1.

Preferably, the vibration generator 6 at least substantially a common plane, here horizontal plane arranged.

Preferably, the vibration generator 6 are aligned at least substantially horizontally. This is also realized as needed in the first embodiment.

Preferably, the at least substantially coaxially arranged vibration generator 6 are pivotable relative to each other, more preferably about vertical pivot axes. The pivoting is preferably again on curved slots 9, as already explained.

Incidentally, in the third embodiment, the other embodiments and explanations to the first embodiment preferably apply correspondingly or in addition.

Particularly preferably, the oscillating arrangement 1 or the frame 5 is designed such that the vibration generator 6 optionally in the various in the Fig. 1 to 5 shown alignments or configurations can be attached or aligned. For this purpose, the frame 5 preferably has corresponding fastening options, preferably both on the side surfaces 11 and on the upper side 12.

Fig. 6 shows in a perspective, partial view of a proposed screening device 14 with a proposed oscillating arrangement 1 according to a fourth embodiment.

The screening device 14 or oscillating arrangement 1 has a preferably at least substantially rectangular and / or elongated frame 5 with opposite longitudinal sides 15.

The screening device 1 preferably has at least one sieve bottom 16, which is arranged in particular in the frame 5 or between the longitudinal sides 15.

In the illustrated example, the oscillating arrangement 1 has at least two pairs of mutually opposite oscillation generators 6, that is to say at least four oscillation generators 6.

The vibration generator 6 are arranged in pairs coaxially and / or opposite to the frame 5 and the longitudinal sides 15.

In particular, each vibration generator 6 is flanged to the associated longitudinal side 15.

Preferably, each vibration generator 6 penetrates the associated longitudinal side 15 or extends on both sides of the longitudinal side 15 in order preferably to minimize or avoid tilting or bending moments acting on the longitudinal side 6 about the longitudinal extension direction in the respective longitudinal side or side wall. In particular, each vibration generator 6 extends with its imbalance shaft through the associated longitudinal side 15, ie on both sides of the longitudinal side 15 or has two unbalanced shafts arranged on opposite sides of the longitudinal side 15 and in particular mechanically coupled through the longitudinal side 15. Accordingly, it is sufficient for each vibration generator 6 preferably a single drive or motor. However, in principle, other constructive solutions are possible.

The vibration generators 6 are preferably arranged or aligned in a common, in particular horizontal plane.

Fig. 7 shows the proposed screening device 14 or oscillating arrangement 1 in a schematic side view.

The sieve device 14 or oscillating arrangement 1 or the frame 5 is preferably mounted swinging again via spring elements 7.

The proposed screening device 14 or oscillating arrangement 1 can be operated, for example, so that no (preferred) promotion of the bulk material 3 (in Fig. 6 and Fig. 7 not shown for reasons of simplification) takes place in a certain direction. Alternatively or alternatively, a conversion or adjustment can be made that a promotion of bulk material in a in Fig. 7 schematically indicated conveying direction 17, in particular in the longitudinal direction, takes place.

The pairs of opposing or coaxially arranged vibration generators 6 are preferably spaced apart in the longitudinal direction or conveying direction 17, as in FIG Fig. 7 indicated.

If necessary, the pairs of vibration generators 6 can also be arranged in each case in the region of an end and / or application region 18 and / or delivery region 19 of the screening device 14. Specifically, a pair of vibrators 6 are assigned to one end or to the feed area 18 and another pair of vibrators 6 to the other end or the discharge area 19 of the screening device 14, respectively.

The mutually opposite or mutually coaxially arranged vibration generator 6 are preferably synchronously, in particular without phase offset (with respect to the imbalances) operated. The coupling takes place here in particular by a corresponding control or regulation or electronically. However, in principle, a mechanical coupling is possible.

The pairs of oscillators 6, which are offset in particular in the longitudinal direction or in the conveying direction 17, can optionally be operated with the same direction of rotation 20 or opposite directions of rotation 20, in each case particularly preferably with the same speeds or rotational speeds, with a corresponding electrical or electronic coupling or corresponding regulation or control is provided.

Particularly preferably, the sieve device 14 or oscillation arrangement 1 is designed or operated such that the pairs of oscillation generators 6 are operated or operable with a predetermined or adjustable phase offset (with respect to the imbalances), wherein the phase offset is preferably infinitely adjustable or adaptable and, if necessary can also be set to "zero" or switched off.

Particularly preferably, the sieve device 14 or the oscillating arrangement 1 can be operated in such a way that a greater conveying speed results in the region of one end or application region 18 and a smaller conveying velocity for the bulk material in the region of the other end or delivery region 19. This is achieved in the same direction operation of the pairs of vibration generators 6 by a corresponding phase offset, in particular caster of the first in the conveying direction 17 pair of vibration generators 6 with respect to the subsequent pair of vibration generators 6.

In particular, at least substantially elliptical oscillatory motions 21 and 22 can be achieved, as in FIG Fig. 7 indicated, wherein the oscillating motion 21 in the region of the first end or task area 18 has a major less inclined to the horizontal axis and thus in the conveying direction 17 larger oscillating component and the oscillating motion 22 in the region of the second end or discharge area 19 a more inclined to the horizontal main axis or Main oscillating component and thus has a smaller acting in the conveying direction 17 vibrating component. It can thus be achieved that bulk material 3 given off in the feed area 18 is conveyed away more quickly from the feed area 18 and is conveyed more slowly in the discharge area 19 or is screened better or longer.

The aforementioned vibration behavior can be supported by appropriate choice or adaptation of the spring or damping properties of the spring elements 7.

Basically, the screening device 14 can also be or form another oscillating device, ie it can not be used for screening, but for conveying bulk material 3 or for other purposes, or be designed for this purpose. In particular, it can also be, for example, a conveying device or conveyor trough, cooling device or the like. In place of the sieve tray 16 then, for example, a conveyor bottom, a conveyor trough or the like is provided. The previous remarks and explanations then apply in particular accordingly. Particularly preferably, in this case too, operation in the sense described, if necessary also with different conveying speeds, can take place via the conveying path or conveying direction 17 by correspondingly different oscillatory movements 21 and 22.

Incidentally, also in the fourth embodiment of the swing assembly 1, the previous embodiments and explanations to the other embodiments preferably apply correspondingly or in addition.

Fig. 8 shows a fifth embodiment of the proposed oscillating arrangement 1. Here are several, in particular three vibration generator 6 arranged around a recess 23 of the frame 5 around. This allows a particularly compact design.

The recess 23 can serve, in particular, for receiving bulk goods 3 (not shown) or other goods, such as cast parts or the like.

Alternatively or additionally, the oscillating arrangement 1 according to the fifth embodiment can also carry or be coupled to a vibrating plate 4, a conveyor trough or another device to be vibrated.

If necessary, other components or components can be mounted on the frame 5 or this oscillating arrangement 1 or be set in vibration, for example, a conveyor trough, screening device or the like, not shown.

In the illustrated example, the vibration generators 6 are preferably aligned parallel to each other.

In the exemplary embodiment, two vibration generators 6 are preferably arranged on opposite sides of the frame 5 and / or next to the recess 23, a vibration generator 6 or the third vibration generator 6 preferably being arranged therebetween and / or below the recess 23.

The active or rotary axes of the vibration generator 6 preferably extend horizontally and / or parallel to the central axis or longitudinal axis of the recess 23.

The frame 5 is formed in the third embodiment, in particular stand-like or block-like.

The frame 5 is here preferably provided with downwardly and / or outwardly projecting feet 24, in particular of a rubber buffer or the like trained spring elements 7 are supported or supported swinging. However, other constructive solutions are possible.

The previous statements and explanations to the other embodiments apply in particular according to or in addition to the fifth embodiment.

In general, it should be noted that the proposed oscillating arrangement 1 allows a modular design.

For example, a plurality of oscillating arrangements 1, in particular for driving, in particular, a vibrating table 2, a conveying channel, a screening device 14 or the like, can be combined. Furthermore, several vibrating tables 2, screening devices 14 or the like can also be combined. The individual oscillating arrangements 1 or oscillation generators 6 can then be operated synchronously or asynchronously and / or with desired phase offsets and / or specific or different oscillatory movements 13, 21, 22.

With the proposed vibration arrangements 1 or according to the proposal coupled vibrators 6 can be different modes of vibration 13, 21, 22, in particular at least substantially linear, circular, elliptical or any other, especially closed waveforms forming waveforms realize.

Preferably, both the phases, ie phase offsets, as well as the frequencies, ie rotational speed or vibration frequencies, can be controlled or controlled.

If necessary, one or more sensors or the like for detecting the oscillatory motion or control or regulation of the oscillatory motion 13, 21, 22 can be used.

Individual aspects and features of the various embodiments can be implemented independently of each other, but also in any combination.
