Definitions
- the present invention relates to a vibratory conveyor according to the preamble of claim 1.
- Such vibratory conveyors are used in many industries, for all sorts of materials, as far as they are even conveyed by a vibrating conveyor.
- the pourable materials are discharged onto a conveyor element, usually a conveyor trough, which then performs a cyclic forward / upward movement with a corresponding return - the vibration - whereby the individual particles of the material are thrown forward and at the same time slightly thrown.
- the conveying element carries out the return flow before the particles rest on it again, so that with the next forward / upward movement the particles can be conveyed one step further.
- Vibratory conveyors have correspondingly a vibrating carrier arrangement for the resting on her, for example, depending on the material or other criteria designed, exchangeable conveying element, wherein the carrier assembly is offset by a drive assembly in the desired vibration.
- the drive arrangement of the vibrating conveyor (reaction forces) also oscillates, with the result that the bearing of the vibratory conveyor must be formed by, for example, elastic supports or feet in order to reduce the vibration vibrations of the drive arrangement introduced into the ground, otherwise considerable noise generated and adjacent machinery or equipment can be disturbed.
- Vibratory conveyors in particular those with a conveyor trough are difficult to design, are largely produced on the basis of empirical findings and compared in trial with the material to be conveyed in terms of frequency and throw angle.
- a disadvantage of the known vibratory conveyor relates to the time-delayed controllability of the output at the end of the conveyor element or the conveyor flow mass, which drifts more or less constantly without regulation, either because of the irregular filling of the conveyor element or other influences, which is particularly important in the gravimetri- Dosage (if a vibratory feeder is placed on a scale) is problematic, but also creates problems with volumetric dosing.
- FIG. 2 shows two diagrams for the flow of the bulk material in a vibratory conveyor according to FIG.
- Fig. 4a shows schematically the subdivision of the conveyor trough of a vibrating conveyor
- FIG. 5a is a view of a vibratory conveyor according to the preferred modification of the first embodiment of Figure 3b,
- FIG. 5b is a view from the side of a functional unit of the vibrating conveyor of Figure 5a in detail
- Figure 5c is a view obliquely from below of the functional unit of Figure 5b
- FIG. 6 schematically shows a second embodiment of a vibrating conveyor according to the invention
- FIG. 7 a shows schematically the geometric conditions according to the invention in the second embodiment according to FIG. 6, using a two-mass model
- FIG. 7b shows, schematically with reference to a two-mass model, the geometrical conditions according to the invention in the second embodiment according to FIG. 6 in a preferred modification
- Fig. 8a is a view of a conveyor trough of a vibrating conveyor undergoing deformation vibration during operation
- Fig. 8b is a diagram schematically showing a modification for compensating for the deformation vibration of Figs
- FIG. 1 shows schematically a vibrating conveyor 1 according to the prior art, which is mounted on the substrate 2 via a bearing arrangement 3 with elastic feet or supports 4a, 4b, and which has a drive arrangement 5, which via a translational Vibra- tionschulsan Aunt 6 a vibrating carrier assembly 8 drives on which a here designed as a conveyor trough 9 conveyor element is arranged with a rear end 10a and a front end 10b.
- the vibratory motion assembly 6 is generally considered to be a designed lel Entry, here with in operation always the same deforming and synchronously moving leaf springs 7a and 7b as the handlebar of the parallel guide.
- the conveying channel 9 is loaded via a filling channel 11 at the rear end 10a with bulk material 12 (cereals, pharmaceutical products, plastic granules and powders of all kinds or metallic materials of all kinds, etc.), which at the front end 10b of the vibrating conveyor 1 is delivered.
- bulk material 12 cereals, pharmaceutical products, plastic granules and powders of all kinds or metallic materials of all kinds, etc.
- the drive arrangement 5 generates the vibratory movement of the carrier arrangement 8 in a known manner, which is guided via the leaf springs 7 a, 7 b, so that the carrier arrangement 8 moves in a translatory, cyclical motion (the vibratory movement) in the direction of the drawn arrows 13 a relative to the drive arrangement 5.
- 13b executes.
- the leaf springs 7a, 7b are shown in the figure in a deflected position, while the dashed line position corresponds to its rest position (between the two deflected positions).
- the vibratory movement is slightly inclined with respect to the conveying direction 14, this inclination corresponds to the throwing angle at which the vibrating conveyor 9 throws the bulk material to be conveyed forward.
- the drive assembly 5 is exposed during operation to the reaction forces of the carrier assembly 8, with the result that it itself is subjected to a vibratory motion in inverse proportion of the masses of the carrier assembly 8 and its mass - this vibration vibration of the drive assembly 5 is reduced via the elastic supports 4a, 4b introduced into the ground 2, so that disturbing noise and the surrounding equipment disturbing vibrations only reduced or no longer disturbing.
- Figure 1 shows a vibratory conveyor 1 with a vibrating in operation carrier assembly 8 for a conveyor element or a conveyor trough 9 in which material to be conveyed 12 is conveyed, with a drive assembly 5 for the support assembly 8 and a bearing assembly 3, the vibration vibrations of the vibratory conveyor 1 reduced into the underground.
- the vibration conveyors of this type have the disadvantage of being difficult to control, since the output mass flow of the bulk material 12 changes only slowly when the operating parameters change and the desired, new value is reached stably only after a few seconds (see FIG ). This is disadvantageous for the control, not only when a highly constant operation, as is the case for example in pharmacy, but also when the promotion is to be driven precisely along a ramp.
- Figure 2 shows two diagrams 20 and 25 for the flow of the bulk material in the conveyor trough 9 of the vibratory conveyor 1 ( Figure 1) according to a simulation of the applicant, wherein the flow of the bulk material 12 at the front end 10 b ( Figure 1) of the conveyor trough is shown.
- the graphs of Figure 2 show the ratios with an increase in flow rate with an increase in mass flow of about 0.012 kg / s to 0.031 kg / s.
- the diagrams are based on a simulation calculation by the Applicant, which is confirmed by measurements, but can advantageously be used for direct comparison with the vibratory conveyor according to the invention (see Figure 4b).
- the curve 21 shows the speed v x in the conveying direction 14 (FIG. 1) of the bulk material 12 (as mentioned above at the front end 10b of the conveyor trough 9, see FIG. 1) over the time in seconds (s).
- the vibratory conveyor is operated at a lower delivery rate.
- the delivery rate is increased, with the bulk material velocity v x rising practically without delay from the previous one (section 22) to the new, stable velocity in the time segment 24, s. the discontinuity in the time segment 23, in which the change of the speed v x takes place to the new value.
- the diagram 25 shows the mass flow kg / s in the conveying direction 14 ( Figure 1) of bulk material 15 at the front end 10b of the conveyor trough 9.
- FIG. 1 schematically shows a first embodiment according to the invention of a vibratory conveyor 30 which can be controlled virtually instantaneously, ie whose mass flow at the front end 10b of the conveyor trough 9 reaches the stable value after the change of the delivery rate immediately, virtually without delay (see the diagrams of FIG. 4b).
- the drive arrangement 5, the translatory vibration movement arrangement 6 with two leaf springs 7a, b shown here in their rest position, as well as the carrier arrangement 8 with the conveying element 9 designed here as a conveyor trough 9, are visible. It is also possible to provide instead of the leaf springs 7a, 7b, for example, a rigid, parallel to each other running handlebars having Parallelogrammation, in which case the drive for the vibratory motion must be designed accordingly, since the restoring forces of the leaf springs 7a, 7b missing.
- the bearing arrangement 3 has two rigid links 33a and 33b, which are articulated on the ground 2 via articulation points 34a, 34b and on the drive arrangement 5 via articulation points 35a, 35b, are always aligned parallel during operation, and thus form a parallelogram guide Form parallel guide, which connects the drive assembly 5 with the substrate 2.
- the means are provided which have a parallel guide provided in the bearing arrangement (3), preferably a parallelogram guide with two rigid links (33a, 33b).
- the articulation points 35a, 35b reciprocate on a curve 36a, 36b, corresponding to the double arrows shown.
- the geometry of the links 33a, 33b is designed such that in the rest position of the leaf springs 7a, 7b (shown in the figure), the tangent to the curves 36a, 36b in the articulation points 35a, 35b is essentially an incline.
- the arrows 37, 38 not only show the direction of the vibration movement, but also the force acting on the carrier arrangement 8 by the drive arrangement 5 (arrow 38) and the reaction force acting on the drive arrangement 5 (arrow 37).
- the drive assembly 5 can freely perform a vibration vibration, which is triggered by the reaction forces arising during the drive of the support assembly 8, here in the same direction (the vibration direction), but in push-pull to this.
- the substrate 2 is now decoupled from this vibration vibration, since the drive assembly 5 can move against this unrestrained in the direction of vibration thanks to the formation of the bearing assembly 3.
- the forced operation prevents tilting of the drive assembly 5 relative to the substrate 2 due to the torques generated during operation. These moments are caused by the distance of the centers of gravity 31,32 perpendicular to the direction of vibration (according to the arrows 37,38) and are introduced by the rigid links 33a, 33b in the ground 2, but cause little disturbing noise nor the environment disturbing vibrations.
- the means for suppressing the deviation are preferably designed to suppress in operation a tilting movement of the conveying element (which is designed as a conveying trough 9 in the embodiments shown) in a vertical plane lying in the conveying direction 14.
- the vibrating element can be of any desired design, for example as a plate or tube, as the person skilled in the art envisages with regard to the conveying needs in the specific case.
- the upper articulation points of the links of the bearing assembly 3 are arranged on the support assembly 8, and not on the drive assembly 5, in which case the deflection of the handlebars is greater, since the amplitude of the vibrating movement of the conveyor trough. 9 due to their smaller mass is greater than that of the drive assembly 5.
- the vibration vibrations are equally effectively decoupled from the ground 2, and introduced the same moments in this, as is the case in the embodiment of Figure 3a.
- the means for suppressing the deviation have a bearing arrangement 3 which comprises the vibratory conveyor 40, 60, 90, 100 (see also the following figures) for a positively guided, substantially translatory movement in the direction of the throwing angle (arrow 38). supports the carrier assembly 8 and wherein preferably the bearing assembly 3 engages the drive assembly 5.
- FIG. 3b shows a vibratory conveyor 40 as a preferred modification of the first embodiment of the invention shown in FIG. 3a.
- the drive arrangement 5 is modified by the distribution of its mass, for example by the arrangement of an additional mass 41, such that its center of gravity 42 lies on a straight line which passes through the common center of gravity 32 of the support assembly 8 with the conveyor trough 9 (preferably filled according to operation) and parallel to the direction of vibration, ie has a slope in the amount of the throw angle.
- the distance between the centers of gravity 32,42 on a perpendicular to the direction of vibration is substantially zero, ie there are no more tilting moments.
- the background 2 is thus not only decoupled from the vibration vibrations of the vibrating conveyor 40, there are also no tilting moments introduced into it.
- the tilting moments are already substantially reduced if the slope of the straight line from the throw angle preferably 20 ° or less, for sensitive environment particularly preferably 10 ° or less and, for an interference-free environment to keep, more preferably 5 ° or less, and most preferably essentially corresponds to the throw angle, if the vibration vibrations of the drive assembly 5 and also all vibration moments from the ground 2 to be decoupled.
- the person skilled in the art will keep the deviation from the throw angle smaller for a conveying element which is long in the conveying direction 14 than for a short conveying element.
- the means for suppressing the deviation have an arrangement of the center of gravity of the carrier arrangement with the conveying element resting thereon and the center of gravity of the drive arrangement on a straight line in the direction of the throwing angle, the direction of the straight line preferably being 20 ° or less from the throwing angle , more preferably 10 ° or less and most preferably 5 ° or less deviates from the throwing angle, and most preferably substantially corresponds to the throwing angle.
- FIG. 4a shows a longitudinal section through the filling channel 11 and a conveyor channel 9 of a vibration conveyor, wherein the bulk material 15, which is conveyed in the conveyor channel 9 by vibration movements, emerges at its front end 10b.
- the conveyor trough 9 is conceptually divided into 4 sections i, ii, iii and iv.
- the bulk material 15 flows from the filling channel 10 through each section i, ii, iii and iv until it is discharged from the conveyor channel 8.
- FIG. 4b shows two diagrams 45 and 55 for the flow of the bulk material 12 in the conveyor trough 9 of FIG. 3a according to a simulation by the applicant, the dynamics of the bulk material 12 being illustrated in the four sections i to iv.
- the graphs of Figure 4b show the ratios for an increase in feed rate with an increase in mass flow of about 0.008 kg / s to 0.025 kg / s.
- the diagram 45 shows the velocity v x in the conveying direction 14 (FIG. 1) of the bulk material 15 in each of the four sections i to iv (FIG. 4 a), namely according to the curve 46 in the section i, the curve 47 in the section ii, the curve 48 in section iii and curve 49 in section iv.
- the delivery rate is increased, with the bulk material speed increasing in all sections i to iv simultaneously and practically without delay from the previous (time section 50) to the new, stable speed (section 51), s. the discontinuities in the curves 46 to 49 in the period 52nd
- the change in the velocity v x of the bulk material 12 in the conveying direction 14 (FIG.
- the graph 55 shows the mass flow kg / s in the conveying direction 14 (Figure 3a) on bulk material 12 in each of the four sections i to iv ( Figure 3a), namely according to the curve 56 in section i, the curve 57 in section ii, the curve 58 in section iii and curve 59 in section iv.
- the mass flow shows virtually the same value in all sections i to iv.
- the mass flow increases simultaneously and without delay in all sections i to iv, in contrast to the prior art (diagram 25 of FIG. 2) also in section iv, i. at the front end 10b of the conveyor trough 9 ( Figure 4a).
- the time interval 51 in which the change in the mass flow takes place in section iv has fallen from about 3.5 s to less than 1/10 s, in contrast to the prior art (see diagram 25).
- the massively improved behavior of the mass flow in section iv (FIG. 4a) with a change in delivery rate as mentioned above is due to a deviation of the vertical component of the vibratory movement of the vibratory conveyor during operation of the vibratory conveyor the front end of the conveyor element 10 b suppressed from that of the rear end 10 a, ie in comparison with the prior art for good controllability is partially or substantially completely reduced.
- This (essentially avoided according to the invention) switching takes place slowly, in the range of seconds, and has the consequence that the mass flow also changes slowly in a vibration conveyor according to the prior art according to FIG.

Also visible are the drive assembly 5, its center of gravity 42 and the leaf springs 7a, 7b, which connect them to the carrier assembly 8.
- the centers of gravity 32, 42 lie on a straight line (indicated by the arrows 91, 92) whose inclination corresponds to the throw angle (to relieve the figure, a possible additional mass 41 (FIG. 3 b) is omitted), so that no tilting moments occur during operation of the vibrating conveyor 90 arise.
- the bearing assembly 3 has schematically shown, elastically deformable supports 93a, 93b, which decouple by their elastic deformation of the ground 2 of vibration vibrations of the drive assembly 5.
- the supports 93a, 93b are designed to suppress a deviation of the vertical component of the vibratory movement of the front end 10b of the conveying element 9 formed as a conveying channel 9 from that of the rear end 10a.
- FIG. 7a schematically shows the geometry and the configuration of the supports 93a, 93b of the vibration conveyor 90 of FIG. 6:
- Dashed lines indicate the drive assembly 5 and the carrier assembly 8, with their focal points 32,42.
- the center of gravity 32 of the carrier assembly 8 also preferably comprises the mass of the discharge element omitted for the relief of the figure, which is particularly preferably filled operationally.
- the centroids 32, 42 are on a straight line in the direction of the throwing angle, more preferably with an accuracy of 5 ° or less, i. most preferably substantially in the direction of the throw angle.
- the double arrow 94 symbolizes this straight line, and shows the movement of the centers of gravity 32,42 in push-pull operation towards each other and away from each other. This eliminates a tilting of the vibratory conveyor 90 due to the vibration movement, although it is mounted freely movable relative to the substrate 2.
- bearing points 96a, 96b are provided, on which the spring units 93a, 93b attack.
- the spring units 93a, 93b each have a horizontally oriented elastic spring 97a, 97b, which face each other, such that their lines of action coincide and go through the center of gravity 42.
- a vertically oriented elastic spring 98a, 98b is provided, each with a vertical line of action. All the springs 97a, 97b, 98a, 98b are arranged between the base 2 and its associated bearing point 96a, 96b and have the same spring constant.
- the center of gravity 42 is located in the middle between the bearing points 96a, 96b.
- the conveying element arranged thereon likewise vibrates in a translatory manner at the throwing angle, so that during operation of the vibrating conveyor a deviation of the vertical component of the vibrating movement of the front end of the conveying element from that of the conveyor rear end despite the resiliently deflectable in all directions deflection of the drive assembly 5 is suppressed.
- These means preferably have an arrangement of the center of gravity 32 of the carrier arrangement 8 with the conveying element resting on it and the center of gravity 42 of the drive arrangement 5 on a straight line in the direction of the throw angle, wherein the slope of the straight line from the throw angle is particularly preferably 10 ° or less and very preferably 5 ° or less deviates from the throwing angle and most preferably corresponds substantially to the throwing angle.
- these means further preferably have a modified bearing arrangement 3 with two, in the conveying direction 14 spaced, resiliently effective bearing units 93a, 93b, which are supported on the substrate 2 and engage the drive assembly 5 in bearing points 96a, 96b, each bearing unit 93a, 93b is effective in the horizontal and in the vertical direction with the same spring constant and the straight line, on which the centers of gravity are 32,42, a connecting line between the bearing points 93a, 93b essentially borrowing intersects in the middle.
- FIG. 7b shows a corresponding vibratory conveyor 100 with a drive arrangement 5 whose center of gravity 42 does not lie on the carrier, but on the straight line defined by the double arrow 94 which intersects the carrier 5 in the middle.
- the spring units 93a, 93b are formed the same as those of the vibratory conveyor 90 of Fig. 7a.
- This embodiment is also according to the invention, since it has the same characteristics as the vibration conveyor 90 of Figure 7a with respect to the vibratory movement of the conveyor element.
- An advantage of the vibratory conveyor 100 is that the restriction "center of gravity 42 in the middle between the connecting straight line of the bearing points 96a, 96b" is omitted for the design of the drive assembly 5, since the center of gravity only on the straight line in the direction of the throw angle through the center of gravity of the support assembly 8 preferably together with the conveying element 9) must lie.
- This can simplify the construction of the drive assembly 5.
- at least one of the bearing points 96a, 96b on the bearing assembly 5 slidably (horizontally and / or vertically) is formed. Then, in the specific case, with a given center of gravity 42 of the bearing arrangement 5, the person skilled in the art can simply move the bearing points 96a, 96b so that the geometric relationships according to FIG. 7a or 7b are maintained, namely the straight line in the direction of the throwing angle on which the center of gravity points 32 , 42, the connecting line between the bearing points 96a, 96b cuts in the middle.
- the drive arrangement may comprise a mass element, which is preferably arranged adjustably in the conveying direction 14 on the drive arrangement 5 such that the center of gravity 42 of the drive arrangement 5 can be predeterminedly changed in its position.
- the center of gravity 42 can be brought to the going through the center of gravity 32 of the support assembly straight line in the direction of the throw angle (which intersects the connecting line between the bearing points 96a, 96b in the middle).
- the throw angle of the support assembly 8 may be adjustable, for example by adjustable on the support assembly 8 engaging leaf spring holders 67a, 67b ( Figure 5a).
- an adjustable throwing angle together with an adjustable mass element, is also advantageous in an embodiment according to FIGS. 3 a to 5 c.
- FIG. 8 a shows a view of a conveying element designed as an elongate channel conveyor 105 for a vibratory conveyor 30, 40, 60, 90, 100 (FIGS. 3 a to 7 b) according to the present description.
- the vibration conditions vibration frequency, vibration amplitude, length, formation of the cross section, etc.
- an excitation in the resonant frequency of the conveyor element may in operation even with a pure translation of the support assembly 8 to deformation vibrations in a region 106 of the conveyor trough 105 shown here, which result in a cyclical deflection of the conveyor trough 105, so that their front end 107b opposite the rear end 107a in accordance with the double arrow 108 swings up and down.
- FIG. 8b shows a vibratory conveyor 110 which is modified with regard to such a deformation oscillation of the conveyor element 105.
- the vibratory conveyor 110 is fundamentally the same as the vibratory conveyor 40 of FIG.
- the articulation point 112a is now arranged to be adjustable on the support assembly 8 and now set slightly shifted in the conveying direction 14.
- the vibration movement arrangement 111 which, in addition to the vibration movement in the direction of the throwing angle, causes a rotation of the carrier arrangement 8 according to the double arrow 116.
- the person skilled in the art can now suitably adjust the articulation point 112a (or, depending on the dynamics of the vibration conveyor 110, one or more of the articulation points 112a, 112b, 113a, 113b) in any direction (by simulation or experiments) such that the Deformation vibration 108 is at least partially compensated by the rotation 116.
- the articulation points 34a, 34b, 35a, 35b of the links 33a, 33b can be adjusted (or the length of a link 33a, 33b) to compensate for the deformation vibration 108 of the conveyor trough 105.
- the use of a vibrating motion arrangement 111 preferably appears, since then only the smaller mass of the carrier arrangement 8 with the conveying trough 105 has to be rotated during the vibration.
- the means for suppressing the deviation (116) are formed, during operation, a deflection of the front end (107b) of the conveying element (105) by a deformation oscillation 108 by a rotational movement superimposed on the vibratory movement of the carrier assembly (8) at least partially compensate.
- the means for suppressing the deviation preferably have an operable guidance of the carrier arrangement 8 on the drive arrangement 5 by a vibration movement arrangement 111 which, during operation, causes a translational and rotary relative movement of the carrier arrangement 8 with respect to the drive arrangement 5, wherein the vibration movement arrangement 111 is preferred Leaf spring assembly 114a, 114b is formed.
- the vibration movement arrangement 116 has links 114a, 114b which are articulated at one end to the carrier assembly 8 and the other end to the drive arrangement 5 via articulation points 112a, 112b, 113a, 113b are, wherein at least one of these articulation points 112a, 112b, 113a, 113b is arranged adjustable in the conveying direction 14 or in another direction on the support assembly 8 or on the bearing assembly 5.
