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 unstable 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.
  • the belt 2 shows a first exemplary embodiment of a device according to the invention.
  • an oloid-shaped hollow body 4 which is designed, for example, as a mixing vessel and has a closable opening 5.
  • the hollow body 4 is constructed somewhat differently from the oloid shape, in such a way that one segment is cut off and a hollow shaft 6, for example hollow, passes through a surface 7 that cuts off the segment at right angles.
  • the contact line lying on the belt 2 in the two extreme positions of the hollow body 4 is somewhat shortened. This allows the band 2 to be made so much narrower that the shaft 6 can be led out laterally.
  • the guide rail 8 is mounted in a strong frame 11 by means of four spring joints 10 so that it has the influence in the vertical direction can compensate for the tolerances mentioned.
  • the number four is not essential to the invention; six or eight such spring joints 10 can also be provided.
  • the compensation in the horizontal direction is applied by slipping on the endless belt 2.
  • 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 only 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.
  • 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 supported 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 shows an elevation again from one side
  • FIG. 5b shows a view from above.
  • a slide 59 runs in each frame 11 and is freely movable in the horizontal direction.
  • the two slides 59 each carry a bearing body 23 which can be rotated about the vertical axis and which contains a sliding bearing for a rod 24 which is axially displaceable through both bearing bodies 23.
  • the rod 24 is fastened to a head 25 which can be rotated about the vertical axis. This sits on a swivel arm 26 rotatable about the vertical axis, the bearing 28 of which is fastened on a crossmember 27 which connects and stabilizes the two frames 11.
  • the shaft 6 is rotatably supported in a ball 29 and axially displaceable; said ball 29 rotates in a carriage 60 which is vertically freely movable on carriage 59.
  • the positive guidance caused by the rod 24 ensures that the hollow body does not run away horizontally with the belt 2, but instead executes its own wobbling movement.
  • the rod 24 By mounting the rod 24 on the swivel arm 26, the transverse movement of the center of gravity of the hollow body 4 is absorbed.
  • a skeleton body 31 formed from partially bent rods 30, as shown in FIGS. 6a, b in plan and elevation. Therefore, a simply designed vessel 40, for example a commercially available chemical drum with rods 32 and bands 33, can be fastened inside the skeleton body 31.
  • 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.
  • the oloid hollow body 4 lies - as in the first exemplary embodiment - on the driven endless belt 2 moving in the direction of the arrow.
  • the shaft 6 runs through the described guide bodies 16, which are connected by means of joints 34 to a push rod 35 each are.
  • the push rods 35 each run horizontally in a bearing 36 which, carried by a carriage 37, can carry out a vertical movement.
  • the carriages 37 are guided on two vertical rails 38 by means of rollers 39.
  • the ends of the push rods 35 facing away from the hollow body 4 are also provided with joints 34, which allow both rotational and pivoting movements with respect to the push rods 35, and in turn are articulated on guide bodies 16.
  • a rod 41 slides through these last-mentioned guide bodies 16, to the center of which a joint 42 is fastened, the other part of which can be rotated about an axis 44 in a pivot bearing 43.
  • the fixed part of the pivot bearing 43 is fixed to a guide 45 which slides on a vertical rod 46.
  • the guide bodies adjacent to the shaft 6 describe the oval curves K 1, K 2 described in FIG the push rods are forced on each other via the rod 41.
  • the vertical movement of the geometric center of gravity of the hollow body 4 is made possible by the guide 45 sliding on the rod 46.
