[0001] The present invention relates to a drive unit capable of driving and forcibly guiding a container along a curved path in one plane, and to a method for processing raw materials, in particular mixtures, in a container driven and forcibly guided along a curved path using the drive unit. [Background technology]

[0002] The drive has the advantage that it moves the container in a forced guided reciprocating motion along a path curve, preferably with only a rotary drive and rotary bearings, in particular without a linear drive. In an optional embodiment, the drive does not comprise linear guides or connecting link guides. Summary of the Invention [Problem to be solved by the invention]

[0003] The object of the present invention is to provide an alternative drive which allows a reciprocating movement along a curved path and which preferably comprises a rotary motor and optionally does not comprise a linear drive. [Means for solving the problem]

[0004] The present invention solves the problem by the features of the claims and in particular by means of a drive which comprises a first lever linked to a fixed first swivel bearing, a second lever linked to a first connected bearing opposite the first swivel bearing of the first lever and with a container holder attached opposite the first lever, a third lever linked to the fixed second swivel lever and a fourth lever linked to a second connected bearing opposite the fixed second swivel bearing of the third lever and with a container holder attached opposite the third lever, wherein the fixed first swivel bearing and the fixed second swivel bearing are fixed relative to each other at a distance from each other or rotatably around the same pivot axis, and at least one, preferably all, of the second and fourth levers are rotatably linked to the container holder. One or all of the second and fourth levers are pivotally (also called rotatably) linked to the container holding portion, such that the second and fourth levers are displaceable relative to each other in the container holding portion, and the container holding portion is attached to the second and fourth levers.

[0005] Since the fixed first swivel bearing and the fixed second swivel bearing are fixed relative to each other, they form fixed bearings at a distance or with a fixed bearing with a fixed pivot axis at a distance or with a fixed bearing with a common pivot axis for the first lever and the second lever pivotably linked to the first lever and for the third lever and the fourth lever pivotably linked to the third lever. The second and fourth levers form floating bearings in the container receptacle relative to the fixed bearings.

[0006] Each of the first and second levers and each of the third and fourth levers are driven by an eccentric drive, which for example has a separate rotary motor or a common rotary motor with an interposed transmission. Each of the first and second levers and each of the third and fourth levers can be linked with an eccentric drive, which is preferably arranged stationarily or displaceably relative to the first and second swivel bearings. Here, the first eccentric drive is linked to the first lever or to the second lever, and the second eccentric drive is linked to the third lever or to the fourth lever. Preferably, the first eccentric drive is linked to the first lever and the second eccentric drive is linked to the third lever. Each eccentric drive can then be linked to a lever by means of a connecting link guide attached to the lever, the connecting link guide extending at least partially along the lever, and a drive pin driven by a rotary motor for movement along a circular path or for circular movement being guided in the connecting link guide.

[0007] The drive unit that reciprocates the container storage unit along the curved path preferably includes a first lever linked to a fixed first swivel bearing, a second lever linked to a first coupling bearing opposite the first swivel bearing of the first lever and having the container storage unit attached opposite the first lever, a third lever linked to a fixed second swivel bearing, and a fourth lever linked to a second coupling bearing opposite the fixed second swivel bearing of the third lever and having the container storage unit attached opposite the third lever. and a lever (8) of the type described above, in which the fixed first swivel bearing and the fixed second swivel bearing are fixed relative to each other at a distance from each other or rotatably around the same swivel axis, at least one of the second lever and the fourth lever is rotatably linked to the container receiving part, and the device has a first eccentric drive part connected, for example linked, to one of the first lever and the second lever, and a second eccentric drive part connected, for example linked, to one of the third lever and the fourth lever.

[0008] The first coupling bearing that pivotally links the first lever to the second lever is a floating bearing, and the second coupling bearing that pivotally links the third lever to the fourth lever is a floating bearing.

[0009] The second lever has a container receptacle mounted opposite the first lever, preferably at a third pivot bearing. The fourth lever has a container receptacle mounted opposite the third lever, preferably at a fourth pivot bearing, the third and fourth pivot bearings being mounted at the container receptacle at a distance from each other or with a common pivot axis. Optionally, the container receptacle is rigidly connected to the second lever opposite the first lever, and the fourth lever is pivotally linked to the pivot bearing at the container receptacle.

[0010] Preferably, the swivel axes of the first and second swivel bearings, the swivel axes of the first and second combined bearings, and the swivel axes of the third and fourth swivel bearings are arranged parallel to one another.

[0011] The first and second swivel bearings and the first and second eccentric drive parts can be mounted in a fixed position on a common frame, the first and second combined bearings and the container receiving part are movable relative to the frame, and the container receiving part is preferably guided only by a second lever linked to the first lever and a fourth lever linked to the third lever.

[0012] The first and / or second eccentric drive can each be formed by a rotary drive with an eccentric drive arm, the drive arm of the first eccentric drive being pivotally connected, for example, to one of the first and second levers and the drive arm of the second eccentric drive being pivotally connected to one of the third and fourth levers.

[0013] Alternatively, the first and / or second eccentric drive can each be formed by a rotary drive formed with a displaceable drive pin in a guide, the drive pin being driven by the rotary drive, in particular along a circular path or in a circular movement. At least one or both of the eccentric drives can comprise a connecting link guide extending along a lever driven by the eccentric drive and a drive pin guided in the connecting link guide and driven by a rotary motor.

[0014] Optionally, the first and second eccentric drives are driven by a common motor, preferably with a gearing, more preferably the gearing is switchable to drive the eccentric drives at a constant or variable speed ratio relative to each other. Preferably the gearing is a belt transmission or a friction wheel transmission.

[0015] The first and second eccentric drives can each be driven by a motor, one or both of which are controlled to drive the eccentric drives at a constant or varying speed ratio with respect to one another. Alternatively, the first and second eccentric drives can be driven by a common, controlled, fixedly mounted rotary motor with a gearing, which is preferably configured to vary the gear ratio and / or the phase shift for both eccentric drives with respect to one another.

[0016] The drive according to the invention is driven by two rotary motors with eccentric drives or one rotary motor with gearing and a cam and has the advantage, for example in one embodiment, of not having a linear drive or linear guide or connecting link guide.

[0017] The drives are configured to drive the reciprocating motion of the container receiving part for reciprocating motion of the container along a path curve at a rotation frequency of one or both eccentric drives, which may be the same or different, e.g., at least 1 Hz. The path curve of the reciprocating motion is generated by superposition of motions along two axes, each having a different frequency and / or with a phase shift of the rotation frequencies of the eccentric drives, over a path along each axis of, e.g., preferably, at least 2.5 mm, at least 1 cm, at least 2 cm, or at least 3 cm or at least 10 cm, e.g., up to 50 cm, up to 30 cm, up to 20 cm, or in a shorter path of up to 10 cm.

[0018] The reciprocating movement of the container receptacle may extend over a distance of, for example, at least 1.5 mm, preferably at least 3 mm, preferably at least 1 cm, preferably at least 2 cm, or at least 5 cm, at least 10 cm or at least 15 cm, for example up to 50 cm, up to 30 cm, or up to 20 cm. More preferably, the eccentric drive for the reciprocating movement of the container is harmonically controlled along a path curve. The reciprocating movement may be nonlinear and sinusoidal, loop-like or arcuate, preferably extending along a path curve that is preferably in a plane or two-dimensional, since in general a reciprocating movement along a nonlinear axis of movement, preferably a path curve that may be a Lissajous figure or a hypocycloid, promotes an even and intensive mixing of the components of the compound contained in the container attached to the container receptacle, even for components of the compound that have similar or identical specific weights. Since each axis of movement itself may extend linearly or arcuately, it is possible to produce a nonlinear movement of the container consisting of a superposition of movements along two axes of movement.

[0019] The container receptacle is brought into a reciprocating motion along at least one path curve, which can be generated by superposition of reciprocating motions along at least two axes positioned at an angle to one another, preferably two of which lie in the plane of the cross section of the container to be mounted in the container receptacle, and which are performed along each axis at different frequencies and / or with a phase shift. The path curve can be generated by superposition of reciprocating motions along two or three axes at different frequencies and / or with a phase shift, and comprises a series of path segments, at least one of which, preferably all of which, comprises or consists of exactly one complete reciprocating motion along an axis along which a reciprocating motion with a lower frequency is performed, and superimposed reciprocating motions with a higher or the same frequency, each optionally with a phase shift, along one or more other axes, where the lower frequency of the complete reciprocating motions forms the frequency of the series of path segments, where at least one of the eccentric drives, preferably both, is controlled to rotate at a frequency. For each path segment, the frequency ratio of the reciprocating motion along the two axes is preferably at most 1:20 or at most 1:15 or at most 1:10, at most 1:4 or at most 1:3, more preferably 1:1 to 1:2, even more preferably greater than 1:1 to 1:2 or 1:1.5, for example having a frequency ratio of 1:1,001 to 1:2 or 1:1.5.

[0020] In the path curves which can be generated by superposition of reciprocating motions along two axes at different frequencies and / or with phase shift of the rotation of the eccentric drive, the axes are preferably in the plane of the cross section of the container to be attached to the container receptacle. In general, the linear or arcuate axes of motion are preferably perpendicular to each other. In general, the path curve does not include a rotation of the container receptacle or the container about its own axis.

[0021] Typically, the device is configured to propel a container receptacle for a container along a curved path formed by the superposition of reciprocating motions of at least two linear axes superimposed on one another and angled relative to one another, the reciprocating motions along the axes being performed at different frequencies and / or out of phase. The axes along which the superimposed reciprocating motions run at different frequencies and / or out of phase form the curved path along which the reciprocating motion of the container receptacle and the containers attached thereto is performed.

[0022] By movement of the container receptacle along the path curve, the apparatus is configured to accelerate the components in the container relative to the container, such that solids and / or liquids contained in the container as components are sheared against the container wall by acceleration and by movement along or against the container wall, thereby being intensively mixed.

[0023] Since the path curve can be set (adjustable) or predefined with different frequencies and / or phase shifts of the mutually superimposed movements along the axis, the device is configured for reciprocating movement of the container receptacle and the container attached thereto along the path curve, and for relative movement of the component or a mixture thereof with respect to the container.

[0024] Typically, the container receiver and the container therein are not rotationally driven, more preferably not rotatable or are rotatably linked about their central axis by, for example, at most 30° or at most 20° or 10°, and not fully rotatable. Typically, and preferably, the container is only propelled in a reciprocating motion along a path curve.

[0025] A settable or predefined path curve with different frequencies and / or phase shifts of the mutually superimposed movements along at least two axes accelerates the mixing of the solids and / or liquids as components and the container attached to the container receptacle relative to the container receptacle. Due to the reciprocating movement of the container, the components in the container and the mixture thereof are propelled into motion relative to the container wall.

[0026] The angles of entry and exit of the solids and / or liquids and mixtures thereof can be determined relative to the vessel wall by the path curve. Optionally, furthermore, the device is configured to move the vessel receptacle and the vessel therein along the path curve with settable acceleration and speed or with predefined acceleration and speed. The device is configured for a settable or predefined path curve and / or settable or predefined acceleration and / or settable or predefined speed along the path curve of the reciprocating motion, so that the solids and / or liquids and mixtures thereof are propelled with settable or predefined acceleration and / or settable or predefined speed relative to the vessel, allowing a predefined or continuous adaptation of the method to the solids and / or liquids and mixtures.

[0027] In general, the path curve can be formed of at least two superimposed individual vibrations, and preferably the path curve resembles a path curve that can be generated by superimposition of reciprocating motions along at least two linear or arcuate axes of motion at different frequencies and / or out of phase. Reciprocating motions along a path curve that resembles reciprocating motions along superimposed mutually orthogonal linear or arcuate axes of motion have different frequencies and / or are out of phase with respect to each other. Therefore, in general, the path curve does not have a circular path.

[0028] The frequency difference may be, for example, 0.01 Hz and / or 0.01-900%. The phase shift of the reciprocating motion along the linear axis may be, for example, 0.01-180°, preferably 1-179° out of 360° corresponding to a complete reciprocating motion. In this case, 0.01-180° of a complete reciprocating motion of 360° is equivalent to 0.0028-50% of a complete reciprocating motion, and 1-179° of a complete reciprocating motion of 360° is equivalent to 0.28-49.7% of a complete reciprocating motion.

[0029] In this case, the linear or arcuate axes of movement are, for example, perpendicular to one another or at another angle, for example between 5 and 85°, in particular in the plane of the cross section of the container and / or perpendicular to the central axis of the container attached to the container receiving part. Optionally, the path curve comprises at least one straight line portion, the end of which is, for example, a vertex of the path curve, at which the solids and / or liquids and mixtures thereof are accelerated by or against the container wall.

[0030] To set (adjust) different frequencies and / or phase shifts of the superimposed reciprocating movements along at least two axes of movement, said reciprocating movements can be related to one another by a transmission or a link guide and driven by a motor. In this case, the motor-driven transmission, which sets the reciprocating movements along the path curve, can have a fixed (constant) or adjustable gear ratio between the superimposed movements along each axis and can be, for example, a continuously or steplessly switchable transmission. Optionally, the transmission can be subject to slip, for example a belt drive, or can be a friction transmission.

[0031] The driven rotational speed of the gearing which propels one or both of the eccentric drives is preferably at least 1 Hz, preferably at least 2.5 Hz, preferably at least 5 Hz, preferably at least 7 Hz, for example up to 50 Hz, up to 40 Hz, up to 30 Hz, up to 20 Hz or up to 10 Hz, where the driven rotational speed of the gearing is the same as the frequency of the reciprocating motion.

[0032] Alternatively, the reciprocating motion along each axis of motion can be driven by a separate motor, with the lower driven rotational frequency forming, for the purposes of the present invention, the frequency of the reciprocating motion as well as the frequency of the series of path segments. In all embodiments, the rotational frequency of each drive motor can be controlled and can be set fixed (constant) or can be variable over the duration of the method.

[0033] The device then allows a path curve to accelerate the components solids and / or liquids and mixtures thereof in a predefined direction towards a target location on the vessel wall, where the geometry of the vessel and its inner wall can be supported in relation to the path curve of the mixing process, so that the path curve can be set depending on the shape and size of the vessel cross section.

[0034] Optionally, the apparatus is configured to modify the path curve of the reciprocating motion and / or the acceleration and / or speed of the reciprocating motion during the method, e.g. by setting (adjusting) in a first step a reciprocating motion along a first path curve and with a first acceleration and speed, and subsequently by setting (adjusting) in a second step a reciprocating motion along a modified path curve and / or with a modified acceleration and / or speed.

[0035] Further optionally, in a first stage the reciprocating motion is a linear reciprocating motion and in a second stage the reciprocating motion is a reciprocating motion along a path curve that transitions into one another, where the path curve can be defined, for example, by a gearing that drives the movement of the container.

[0036] The device allows for predefined or dynamically changeable and oriented acceleration of raw material relative to a container as a process product by setting (adjusting) the path curve and acceleration of the container's reciprocating motion.

[0037] In one embodiment in which the container may be controllably propelled into a linear reciprocating motion in a first stage, the apparatus is configured to move solids and / or liquids and mixtures thereof perpendicular to the container wall with a controllable acceleration that is much greater than the acceleration of gravity and thus essentially independent of the acceleration of gravity, e.g., at least 15 m / s 2 , preferably 25 m / s 2 , preferably at least 50 m / s 2 Or at least 100 m / s 2 Or at least 200 m / s 2Or at least 350 m / s 2 , e.g. 500m / s 2 It has a maximum acceleration of up to

[0038] Typically, the device will have a speed of at least 20 m / s 2 Or at least 100 m / s 2 , e.g. at least 200 m / s 2 , preferably 1000 m / s 2 Up to 300m / s 2 The method may be arranged to accelerate the container receiver and the container attached thereto along the path segment, for example at an apex of the path segment, with an acceleration maximum of up to 100 .mu.m.

[0039] The container receiving portion and the container attached thereto preferably have a velocity of at least 0.5 m / s 2 or at least 1 m / s2 or at least 2 m / s 2 , at least 3.5m / s 2 , preferably at least 60 m / s 2 , preferably at least 100 m / s 2 , at least 150 m / s 2 , at least 160m / s 2 , at least 200m / s 2 , e.g. 300m / s 2 or 450 m / s 2 Up to 260m / s 2 Up to 250m / s 2 The container is propelled into a reciprocating motion along each of the two axes with an acceleration maximum of up to 0.5 m / s, preferably at least 2 m / s, preferably at least 3.5 m / s, for example up to 10 m / s or up to 20 m / s or up to 6 m / s, for example 3-4 m / s, respectively along one of the axes, preferably along each of the axes, where the distance of the movement along at least one axis, preferably along each axis, is for example 0.1-24 cm.

[0040] The container receptacle and the container attached thereto can be propelled into a reciprocating motion extending along each axis over a distance of, for example, at least 1 mm or at least 2.5 mm, at least 1 cm, preferably at least 2 cm, or at least 5 cm, at least 10 cm or at least 15 cm, for example up to 100 cm, 50 cm or up to 20 cm, respectively. More preferably, the reciprocating motion of the container is harmonic. The reciprocating motion of the container receptacle is non-linear in a first stage, and in general the path curve is non-linear and may be, for example, sinusoidal, loop-like or arcuate, preferably extending along a so-called Lissajous figure or hypocycloid, preferably in a plane or two-dimensional. Preferably, the reciprocating motion is linear in a first stage and along at least two mutually transitioning non-linear path segments in a second stage, said path segments each forming at least one vertex for the path curve. This is because, in general, movement along a non-linear path curve, e.g., a path curve in which each path segment has at least one vertex, promotes collision of solids and / or liquids and mixtures thereof, e.g., perpendicular to a container wall and movement along the container wall.

[0041] Preferably, the reciprocating motion comprises a reciprocating motion along a path curve comprising at least two, preferably at least three, more preferably at least four different path segments each having at least one apex and preferably transitioning into one another in a time sequence, preferably program-controlled. Each axis of motion along which motion is superimposed onto the path curve can itself extend linearly or arcuately, so that it is possible to produce a non-linear motion of the container receptacle along a series of path segments consisting of a superposition of motions along two axes of motion. The apexes of the path segments and the portions therebetween are determined by the frequency difference and / or phase position of the superimposed reciprocating motions along the at least two axes. In general, the device can be configured to change the frequency difference and / or phase position during the reciprocating motion.

[0042] The invention will now be explained more precisely with reference to the drawings. [Brief description of the drawings]

[0045] 1 shows an embodiment of the drive according to the invention, which extends between a fixed first pivot bearing 1 and a fixed second pivot bearing 2 on the one hand, and a floating bearing on which a container receptacle 3 is mounted. A first lever 4 is pivotally linked to the first pivot bearing 1, and at its end opposite the first pivot bearing 1, a second lever 5 is pivotally linked by means of a first connecting bearing 6. At its end opposite the first connecting bearing 6, the second lever 5 is connected to the container receptacle 3, preferably pivotally linked thereto. A third lever 7 is pivotally linked to the second pivot bearing 2, and at its end opposite the second pivot bearing 2, a fourth lever 8 is pivotally linked by means of a second connecting bearing 9. At its end opposite the second connecting bearing 9, the fourth lever 8 is connected to the container receptacle 3, preferably pivotally linked thereto. Generally, the second lever 5 and the fourth lever 8 can be attached to the container storage section 3 by the second lever 5 and the fourth lever 8 being linked to each other at the fourth pivot joint section 10 and the container storage section 3 being attached to the axis of the fourth pivot joint section 10 or to one of the second lever 5 and the fourth lever 8.

[0046] In the embodiment shown, the drive comprises two eccentric drives 11, 12 each with a controlled rotary motor 13, 14. The first eccentric drive 11 comprises a fixedly mounted first rotary motor 13 which is coupled to the first lever 4 by means of an eccentric first drive arm 15, which drives the first lever 4 for pivoting about the first pivot bearing 1. The second eccentric drive 12 comprises a fixedly mounted second rotary motor 14 which is coupled to the third lever 7 by means of an eccentric second drive arm 16, which drives the third lever 7 for pivoting about the second pivot bearing 2. The first rotary motor 13 and the second rotary motor 14 are preferably arranged in a fixed position by being mounted on a frame to which the first and second pivot bearings 1, 2 are also mounted.

[0047] 2 shows in detail the fourth pivot joint 10, at which the second lever 5 and the fourth lever 8 are linked to one another. The container receptacle 3 can be rigidly connected to the second lever 5 at a fixed point 17, whereas the fourth lever 8 is not directly connected to the container receptacle 3 but is in particular freely pivotable relative to the container receptacle 3.

The second eccentric drive is driven by a second rotary motor 14, which drives a second drive pin 21 along a circular path. The second drive pin is guided in a second guide 20 extending along the third lever 7, so that the circular movement of the second drive pin 21 drives the third lever 7 to pivot about the second pivot bearing 2. A frame 23 is shown diagrammatically, on which the first and second pivot bearings 1,2 and the first and second eccentric drives 11,12 are mounted. [Explanation of symbols]
