Definitions

  • the present invention relates to a device for driving a wobble body according to the preamble of patent claim 1.
  • CH patent 500,000 describes a device for generating a wobbling movement. This consists of a body which the inventor Paul Schatz calls an "oloid" in his book “Rhythm Research and Technology” (Stuttgart 1975). According to CH-A1 500 000, this oloid is driven by an endless belt on which the oloid is placed.
  • a device is known with which a body is also set in a tumbling motion.
  • the type of wobble is completely different from what is meant here.
  • a cylinder body is rotated uniformly about its longitudinal axis.
  • This first cylinder body is designed in such a way that it is suitable for receiving a second, essentially likewise cylindrical body.
  • the longitudinal axes of the two cylinder bodies now intersect at a certain, predetermined angle.
  • the longitudinal axis of the second cylinder body used - which is generally proposed as a drum-shaped receptacle for mixed material or the like - describes a double cone about the longitudinal axis of the first cylinder body in the course of one revolution of the first cylinder body.
  • the center of gravity of the contents moves both radially and axially with respect to the center of the receptacle. Because of the uniformity of the rotation of the second cylinder axis about the first, however, the movement characteristics of both the receptacle, the contents and its center of gravity are completely different from those envisaged here.
  • the object on which this present invention is based is to create a drive for an oloid body which overcomes the disadvantages mentioned and is equally suitable for oloids within a large dimensional range.
  • FIG. 1a, b schematically show an oloid in different layers on an endless belt 2 which rotates in the direction of the arrow with a uniform movement.
  • the horizontally running band 2 three levels E1, E2, E3 are erected in the spirit, which run vertically, that is perpendicular to the horizontal plane.
  • the levels E1, E2 flank the endless belt 2 and are parallel to its direction of movement; the third level E3 is both perpendicular to the horizontal plane and on the levels E1, E2.
  • the oloid If the oloid is initially at rest in its stable equilibrium position on band 2, its line of contact lies in the line of intersection of the horizontal plane (or band 2) with plane E3. Furthermore, the oloid has a longitudinal axis which, in the said equilibrium position, also extends in the plane E3 and pierces the planes E1, E2 in two points, the penetration points D1, D2.
  • the penetration points D1, D2 of the longitudinal axis 3 of the oloid on the planes E1, E2 each describe an oval curve K1, K2.
  • the sizes and shapes of the oval curves K1, K2 depend on the lateral spacing of the planes E1, E2 from the respective edge of the band 2nd
  • Fig. 1a shows three positions of the oloid 1 during a full rotation about the - not spatially fixed - longitudinal axis 3; In Fig. 1b this number is reduced to two for the sake of clarity, the top and the lowest extreme position of the intersection points D1, D2 indicate.
  • An oloid-shaped hollow body 4 which is designed, for example, as a mixing vessel and has a closable opening 5, lies on a roller carpet 51.
  • the roller carpet 51 consists of a plurality of short free-running rollers 52 with mutually parallel axes of rotation, the direction of which is perpendicular to the plane of the drawing in FIG. 2a and parallel to that in FIG. 2b.
  • the axes of the rollers are thus perpendicular to the two levels E1, E2.
  • the direction of these planes E1, E2 is referred to as the direction of movement of the wobble body.
  • the hollow body 4 is constructed differently from the oloid shape, in such a way that a segment is cut off in each case, and a, for example, hollow shaft 6 passes through a surface 7 that cuts off the segment at right angles.
  • the contact line resting on the roller carpet 51 in the two extreme positions of the hollow body 4 is thus somewhat shortened. This allows the roller carpet 51 to be made so much narrower that the shaft 6 can be led out to the side.
  • an endless belt 2 is also in accordance with the invention, but the belt is only moved passively, as is also the case for the roller carpet 51. This embodiment variant also applies to the second exemplary embodiment according to FIG. 6.
  • Fig. 1a with K1, K2 oval curves are realized as oval guide rails 8, only one of which is shown, since - provided the lateral distances from the roller carpet 51 are the same, and the hollow body 4 along the center line of the roller carpet 51 moves - are congruent.
  • the shaft 6 is actively guided along the guide rail 8 by means of a carriage 9, as described in detail with reference to FIG. 3.
  • the carriage 9, which is only shown schematically in FIG. 2, is shown in detail in FIG. 3.
  • the guide rail 8 naturally differs in shape from the shape of the oval curves K1, K2, since this is valid for mathematical axes; the distance of the axis of rotation of the shaft 6 from the limits of the guide rail 8 is to be considered.
  • the guide rail 8 is mounted in a strong frame 11 by means of four spring joints 10 in such a way that it can compensate for the influence of the tolerances mentioned in the vertical direction .
  • the number four is not essential to the invention; six or eight such spring joints 10 can also be provided.
  • FIGS. 5a, b Said active guidance of the carriage 9 along the guide rail 8 is described in detail in FIGS. 5a, b.
  • the elements entered in FIGS. 2a, b and designated by the numbers 58, 59 are related to this.
  • the carriage 9 shown in plan view in FIG. 3 a, in partial longitudinal section in FIG. 3 b, consists of a frame 12, which carries two guide wheels 13, for example, with ball bearings with grooves 14. These encompass the guide rail 8.
  • the carriage 9 can therefore move in the plane defined by the guide rail 8.
  • the frame 12 carries a swivel joint 19, the axis of rotation of which is perpendicular to the tangent to the guide rail 8.
  • a plate 20 is rotatably fastened to the frame 12 by means of the swivel joint 19.
  • This plate 20 carries a transverse axis 15, by means of which a guide body 16 is pivotally mounted.
  • the transverse axis 15 is perpendicular to the axis of the swivel joint 19 and has the direction of the tangent to the guide rail 8.
  • the shaft 6 is rotatably and longitudinally displaceable, which is indicated in Fig. 3b by arrows.
  • a roller chain 53 rotates in the guide rail 8, the cross section of which is shown in FIG. 3b.
  • the carriage 9 is driven by this roller chain 53.
  • the frame 12 of the carriage 9 is connected via a pin 54 to the axis of a roller 55 of the roller chain 53 mentioned.
  • FIG. 4 A variant of the carriage 9 shown in FIGS. 3a, b is shown in FIG. 4.
  • the carriage 9 is supplemented by a third guide wheel 18 which is carried by a frame part 22 connected to the frame 12 by a hinge joint 21.
  • the frame part 22 is pressed away from the frame 12 by a spring 17; the third guide wheel 18 thus remains in frictional engagement with the guide rail 8.
  • FIG. 5a, b the roller chain 53 and its drive in connection with the guide rail 8 are shown; in Fig. 5a partially in section, in Fig. 5b in a partially broken plan view.
  • a drive gear 56 is let into the guide rail 8 at one point - for example, at the bottom right of the guide rail 8 in FIG. 2a. This is driven by a motor 58 via a gear 57.
  • Each of the two oval-shaped guide rails 8 carries such a drive consisting of the elements 56, 57, 58.
  • the two motors 58 are fed by a controlled power supply, which is shown schematically in FIG. 2a and is designated by the number 59.
  • the controlled power supply 59 can be designed, for example, in the manner known from CH patent application 849 / 92-6.
  • program control of the motors 58 designed as incremental motors can also be provided, which takes into account the strongly non-uniform movement of the carriages 9.
  • the location-speed profile of the motor 58 can therefore be permanently stored in the numerically controlled power supply 59.
  • Setpoint / actual value comparison of the position of the motor is state of the art and need not be described here.
  • the geometrical forced travel caused by the guide rail 8 from the first exemplary embodiment is replaced by a two-coordinate control consisting of a vertically movable and driven slide 60 and a horizontally movable and driven slide 61.
  • the slide 60 runs in the manner of rails 64 provided frame 11.
  • the slide 60 forms the guide for the slide 61.
  • a ball 62 is mounted in the slide 61, which forms the bearing for the shaft.
  • the drives (not shown) of the carriages 60, 61 are fed by a controller 63 in which the location-speed profile is stored.
  • the drives are the slides to accommodate construction and shape tolerances 60, 61 equipped with sensors that modify the setpoint profile in the controller 63 from the comparison of applied and permissible forces, as is known from robotics.
  • the hollow body 4 runs on the roller carpet 51 as in the first exemplary embodiment.
  • a variant, not shown, for both the first and the second exemplary embodiment is a free-running endless belt that runs over two rollers, which then takes the place of the roller carpet 51.
  • Frames 11 with rails 64, slides 60 and 61 with ball 62 are, of course, duplicated, analogous to the first exemplary embodiment according to FIGS. 2a, b, since a frame 11 is fastened on each side of the roller carpet 51.
  • both the carriages 60 and the carriages 61 move essentially in opposite directions in order to give the shaft 6 that movement which causes the hollow body 4 to wobble.
  • a skeleton body 66 formed from partially bent rods 65, as shown in plan and elevation in FIGS. 7a, b. Therefore, a simply designed vessel 67, for example a commercially available chemical drum, can be fastened in the interior of the skeleton body 66 with rods 68 and bands 69.
  • the shaft 6 can also be hollow. Then the device according to the invention is also suitable for mixing liquid or solid materials in the flow-through method.
  • the shaft 6 is provided at each end with a rotary feedthrough known per se. With such rotary unions, several components can be added; Furthermore, the introduction of measuring probes for pressure, temperature, pH and other parameters is possible without any problems.
