Definitions

  • the invention relates to a drive unit for a mixing and / or kneading machine with at least one tool rotating in a container and also rotating about its own axis, the tool being mounted eccentrically and approximately parallel to its axis of rotation, the rotation of the Rotary body sets the tool in a rotary motion and the driving force acting on the rotating rotary body from a drive motor via a reduction, which has a planetary gear, can be transmitted to the tool, which also rotates about its own axis, that is rotatably connected to a planet gear of the planetary gear, which rolls on a sun gear arranged coaxially to the axis of rotation of the rotating body.
  • Vertical kneading machines are already known, for example with two kneading tools arranged on approximately parallel shafts, one of which is centrally located and is rotated in the kneading container by the other kneading tool.
  • the kneading tools also rotate on their own axis.
  • the kneading tools are equipped with blades, the enveloping circles of which intersect; the speed of rotation of the two kneading tools is so matched that their blades do not touch each other.
  • Vertical kneading machines of this type have proven themselves, for example, when mixing liquid, solid and plastic materials to form tough, plastic or doughy masses.
  • the self-rotation of the kneading tools and the rotational movement of at least one kneading tool is accomplished by a drive motor which sets the rotating basket into a rotational movement via a toothed ring arranged on the outside of a rotating basket.
  • the rotating tool In the interior of the rotating basket, the rotating tool is mounted eccentrically and can be rotated approximately parallel to the axis of rotation of the rotating basket. Due to the rotation of the rotating basket, the eccentrically mounted kneading tool rotating in the container is also set into its circulating movement. Due to a reduction, which has a planetary gear, the driving force of the drive motor is also used for the self-rotation of the kneading tools.
  • a planet gear provided on the shaft of the rotating kneading tool rolls on a sun gear arranged coaxially to the axis of rotation of the rotating basket.
  • a sun gear arranged coaxially to the axis of rotation of the rotating basket.
  • the internal rotation of the rotating kneading tool is converted into a different internal rotation of the centrally arranged kneading tool, however, with regard to the blades intersecting in their respective enveloping circle.
  • the low-viscosity components are often premixed in separate mixers in order to shorten the mixing time.
  • This separate premixing can have a disadvantageous effect, in particular in the case of dangerous, for example explosive or harmful substances, since additional risks and work for the operating personnel arise during the transfer.
  • a rapid orbital movement with high viscosities of the product to be treated also has a disadvantage because too much drive power is required to push the product in front of the rotating kneading paddle. It would be advantageous to have a slow orbital movement with high self-rotation of the kneading tools in order to use the available power as effectively as possible for an intensive kneading process.
  • a change in the rotation of the rotating body or the rotational movement of the tool also changes the speed of its own rotation; the ratio of these two speeds practically always remains the same. It is not possible in this way alone to achieve a desired high speed with a simultaneous slow rotation of the tool and vice versa. If the sun gear is additionally driven via the additional drive, the drive forces overlap and the natural speed of the rotating tool can be increased, for example, while its rotating speed remains the same or may even be reduced. In this way, for example, the stirring or kneading performance of the machine can be easily adapted to the viscosity of the product to be treated.
  • a laborious and complicated exchange of gears or gear parts, for example, can also be dispensed with, such as premixing in separate mixers.
  • the sun gear serves as an output of the additional drive in the planetary gear and is preferably lockable.
  • a sun wheel serving as an output of the additional drive in the planetary gear enables a particularly simple design of the mixing and / or kneading machine according to the invention.
  • the tools that intersect in the enveloping circles of their blades can have strong shear stress fields in the gap between them generate the kneading blades and above all promote the kneading performance of the mixing and / or kneading machine according to the invention.
  • An advantageous development according to the invention provides that a tool arranged coaxially to the axis of rotation of the rotating body is provided, which is in drive connection with at least one rotating tool, and that the central tool is non-rotatably connected to its own sun gear, which with an additional planet gear interacts at least one rotating tool.
  • the tool which is arranged centrally and coaxially to the axis of rotation of the rotating body, is also set to rotate by the rotation of the rotating tool.
  • a further planetary stage is provided for this purpose, the additional planet gear of the rotating tool driving the own sun gear of the central tool.
  • the mixing and / or kneading machine according to the invention can also be designed such that a tool arranged coaxially to the axis of rotation of the rotating body and preferably two tools rotating in the container around the centrally arranged tool are provided.
  • the direction of rotation of the additional motor is reversible and / or its speed is preferably continuously variable.
  • the additional drive can be designed as a motor, in particular as an electric motor, preferably as a DC motor.
  • the speed of such an electric or DC motor could easily be over Change potentiometer.
  • a preferred embodiment according to the invention provides that the additional motor and preferably also the drive motor is designed as a hydraulic motor, the speed of which can be adjusted particularly simply by changing the hydraulic oil supply.
  • a further embodiment of the drive unit according to the invention can consist in that both drive motors, that is to say the additional drive and the drive motor, can be changed in their speed. As a result, the overall working speed within the mixing and / or kneading machine can also be influenced.
  • a drive control which couples the control of the drive motor and the auxiliary drive at least in such a way that when the speed of the rotary movement of the tool (s) rotating in the container is reduced or increased, the self-rotating speed of the tools also changes reduces or increases with a constant ratio of the speeds to each other.
  • a particularly simple stirring and / or kneading machine could have a drive control, for example, in which the control of the two drives is forcibly coupled in such a way that, for example, a slowdown in the rotating movement of at least one rotating tool also slows down the rotational speed of all Tools leads. The ratio of these speeds could be preselected using additional switches, for example.
  • the drive control has two adjustment options, one of which responds to both drives in the same way in terms of their speed, that is to say accelerates or slows down at a constant Ratio of the speeds to each other, while the other adjustment option serves to change the ratio of the speeds of the two drives to each other.
  • the one setting option of the drive control enables simple handling of the drive unit according to the invention, the ratio of the speeds can be changed slightly using the other setting option and, for example, adapted to the viscosity of a product to be mixed.
  • the kneading machine 1 shows a stirring and kneading machine designated as a whole, which is also referred to here briefly as a "kneading machine".
  • the kneading machine 1 for example, liquid, solid and plastic materials can be mixed to form tough, plastic or doughy masses.
  • the kneading machine 1 has three tools 3 arranged in a container 2, the outer tools 3a rotating in the container 2 around the centrally arranged tool 3b. All tools 3 also rotate on their own, vertically aligned axis. From Fig. 1 it is clear that the outer tools 3a are mounted eccentrically in a rotating body 4 and approximately parallel to its axis of rotation.
  • the rotating body 4 has a ring gear 5 on its outside, which is connected to a ring gear 6 a drive motor 7 combs. With the help of the drive motor 7, the rotating body 4 can be set in rotation, which is simultaneously converted into a circular movement of these tools by the eccentric arrangement of the outer tools 3a.
  • the rotating body 4 practically forms the web of a planetary gear 8.
  • the driving force of the drive motor 7 can also be transmitted to the tools 3a rotating about its own axis via a reduction device which has the planetary gear 8.
  • the tools 3a each have a planet gear 9, which roll on a sun gear 10 arranged coaxially to the axis of rotation of the rotating body 4.
  • the self-rotation of the rotating tools 3a is transmitted via a second planetary stage 11 to the centrally arranged tool 3b, which only rotates about its own axis.
  • the central tool 3b is rotatably connected to its own sun gear 12 of the second planetary stage 11, which cooperates with the additional planet gears 13 of the two rotating tools 3a.
  • the tools 3 have blades 14 at their ends arranged in the container 2, which intersect in their enveloping circles.
  • the second planetary stage 11 is reduced so that the blades 14 of the tools 3a and 3b do not touch each other.
  • An advantageous reduction ratio of the natural speeds between the central tool 3b and the rotating tools 3a is, for example, 1: 2.
  • the speed ratio between the self-rotation of the outer tools 3a and their orbital movement remains practically constant.
  • this ratio usually fluctuates in the range from approximately 1: 1 to approximately 4: 1.
  • the viscosity and / or the consistency of the product to be treated changes during processing.
  • the sun gear 10 of the planetary gear 8 of the kneading machine 1 is rotatably supported and has its own additional drive 15 for the rotation of the kneading tools 3. If the sun gear 10 is additionally driven via the additional drive 15, then the driving forces of the additional drive 15 and the drive motor 7 are superimposed.
  • both the drive motor 7 and the auxiliary drive 15 are designed as hydrostatic drives. These drives have the advantage that they can be infinitely adjusted by changing the hydraulic oil supply and can absorb torques even when the machine is at a standstill. If both the drive motor 7 and the auxiliary drive 15 are supplied by a common pump unit, the sum of the drive powers and thus also the maximum power to be transmitted by the reduction gears can be limited in a simple manner. The torques can in turn be limited by a pressure limitation on the drive motors 7, 15 and thus also the maximum torque resulting from the superimposition of the two drive motors.
  • the rotational movement of the outer tools 3a can also be reduced in relation to a high intrinsic rotation of all the tools 3 if the available power is as effective as possible, for example for an intensive kneading process of a product with a high viscosity.
  • High revolving movements would otherwise result in the product being pushed forward in front of the blades 14 of the tools 3, in a corresponding reduction in the output effective for the kneading process, and possibly in a build-up of the product up to the sealing area 16 of the tool shafts, which is particularly the case with the processing of explosive products is particularly dangerous and undesirable.
  • the blades 14 Since the intrinsic rotation ratio of the tools 3a to the centrally arranged and counter-rotating tool 3b, for example 2: 1, does not change even when the speed ratio of the rotational movement of the outer tools 3a to the intrinsic rotation of all tools 3 does not change, the blades 14 also touch the tools 3 never, even though their enveloping circles intersect.
  • FIG. 1 a table with 23 operating states of the kneading machine 1 is attached in FIG.
  • the sun gear 10 of the planetary gear 8 has 23 teeth, the planet gear 9 of the rotating tools 3a in the planetary gear 8 25 teeth, the sun gear 12 of the second planetary gear 11 32 teeth and the planet gears 13 of the second planetary gear 11 16 teeth.
  • the blades 14 of the rotating tools 3a rotate relative to the rotating body 4, regardless of the input and output speeds, always twice as fast as that of the centrally arranged tool 3b.
  • the sun gear 10 and the planet gears 9 need not necessarily be designed as gear wheels, it is important in the second planetary stage 11 that the arrangement of the blades 14 of the tools 3 does not change with respect to one another and the planet gears 13 and its sun gear 12 are therefore expediently meshing with one another Gears are formed. This avoids that the cutting tools 3 in the enveloping circles of their blade 14 touch each other.
  • the direction of rotation, considered relative to the rotating body 4, the tools 3a on the one hand and the centrally arranged tool 3b is always in opposite directions. In Fig.
