Definitions

  • the present invention relates to a floor cleaning machine, in particular a scrubbing or polishing machine, with at least two horizontally suspended roller brushes which are driven to rotate about their longitudinal axis and which perform a rotation which overlaps their rotation and oscillates in opposite directions in the horizontal direction.
  • the invention relates to a floor cleaning machine, in particular a scrubbing or polishing machine with a chassis and at least two cleaning units suspended thereon, each of which has at least two deflecting rollers which can be rotated about their horizontally oriented longitudinal axes, at least one of which is driven in rotation, and one which rotates around them Include cleaning tape.
  • a machine designed as a polishing machine of the type mentioned is known from US-A-4,499,624. It has two polishing rollers arranged next to each other in parallel, which oscillate and rotate in opposite directions. The known machine does not have a chassis; rather, the entire weight of the machine rests on the two polishing rollers. Through the overlapping Rotation and oscillating movement of each polishing roller should improve the polishing performance.
  • a major disadvantage of the known polishing machine is that it lurches about its vertical axis during operation. Because the oppositely oscillating movement of the rollers creates an opposite reaction moment acting on the machine body. This is not only due to the acceleration forces for the two polishing rollers. The friction between the polishing rollers and the surface to be processed also increases the torque.
  • the known machine is therefore practically unusable in those applications in which heavy roller brushes are to oscillate at not only a low speed and / or a surface is to be processed which, in particular due to its roughness, opposes the oscillating movement of the roller brushes with a high frictional force.
  • roller cleaning machines are known and used in the prior art, in which the roller brushes only perform a rotation, but not an oscillating movement. They serve the wet or dry cleaning of floors, especially in halls, offices, shops, but also outdoors.
  • the roller brush (s) or the deflection roller (s) around which the cleaning belt rotates are driven by means of a drive motor or by means of a mechanical coupling with the wheels of the chassis, in particular using a belt drive.
  • the drive motor for the roller brush (s) or the deflection roller (s) can be fed via a cable from the power supply or via an on-board energy supply, in particular in the form of accumulators.
  • larger machines are pushed by the operator or have a travel drive; in the second case, the floor cleaning machine can be designed as a self-propelled machine.
  • the present invention has for its object to provide a floor cleaning machine of the type mentioned, in which the machine does not roll around its vertical axis.
  • the risk that the floor to be cleaned burns when the cleaning machine stops moving should be minimal and at the same time there should be a good cleaning effect.
  • this object is achieved in floor cleaning machines according to the preamble of claim 1 in that the roller brushes are suspended from a chassis and two of them are arranged rotating about the same axis.
  • the arrangement of the roller brushes provided according to the invention results in a complete mass and moment compensation, which is a Vibration of the machine and a lurching around its vertical axis are suppressed.
  • Another advantage of scrubbing machines designed according to the invention can be compared to one conventional machines call higher cleaning performance due to the constantly changing direction of attack of the bristles against the dirt adhering to the floor.
  • This higher cleaning performance of the scrubbing machines according to the invention compared to those according to the prior art means that in the floor cleaning machines according to the invention the contact pressure of the roller brush on the floor can be reduced, which in turn enables the reduction in the power required to drive the roller brush. This results in a longer operating time with one battery filling in a particularly advantageous manner in the case of network-independent machines than in conventional machines.
  • Another advantage of the floor cleaning machine according to the invention is that the boundaries of the processed area do not become apparent as a sharp edge on the floor. Because the limits of the processed strip are "frayed" according to the amplitude of the oscillating movement of the roller brush; the intensity of the tillage decreases within a narrow edge strip, the width of which corresponds to the amplitude of the oscillating movement. This will make the Conventional machines suppressed banding on the floor.
  • roller brushes are particularly preferably suspended on the chassis in such a way that their axes of rotation run transversely to the working direction of the machine, the direction of the oscillating movement likewise running transversely to the working direction of the machine, in the axial direction of the roller brushes.
  • the roller brushes can also be arranged at an angle to the working direction of the machine, and the direction of the oscillating movement can form an angle with the axial direction of the roller brushes.
  • the advantageous effects of the floor cleaning machine according to the invention are particularly pronounced when the maximum speed of the oscillating horizontal movement of the roller brushes essentially corresponds to the peripheral speed of the bristle ends.
  • the direction of movement of the bristles on the floor changes within an angular range of 90 °, namely 45 ° at an angle to the circumferential direction.
  • the drive which sets the roller brushes in oscillating movements, can be realized in different ways. Particularly in the case of small machines, it is expedient to mechanically couple the oscillating movement of the brushes to their rotation, since in this case a separate drive motor is not required for the oscillating movement; In the case of larger machines, it is conversely advantageous to provide separate drive motors for the oscillating movement and the rotation of the brushes, because the two movements can then be changed independently of one another to adapt to the floor to be cleaned, the degree of contamination and the like.
  • at least one cam disk with axial cams is connected to each roller brush, which cam roller runs on a counter cam fixedly arranged on the chassis. This represents a particularly simple and robust technical implementation.
  • eccentric drives or crank drives In the sense of the above subdivision, these can either be driven by separate motors, or else they are mechanically coupled to the drive motor for rotating the brushes. In both cases, the eccentrics or cranks can act, for example via connecting rods, on a frame that receives the roller brushes and that oscillates with them and is guided in the chassis in horizontal guides.
  • mount the roller brushes in a rotationally fixed but axially displaceable manner on brush shafts which are in turn rotatably but axially fixedly mounted in the chassis. In this way, the oscillating masses can be minimized.
  • the above-mentioned object is achieved in floor cleaning machines with at least two cleaning units, which comprise a cleaning belt rotating around deflection rollers, in that the deflection rollers of two cleaning units are each arranged to rotate about the same axis and perform an opposing oscillating movement in the horizontal direction .
  • the advantages described above, which result with regard to the cleaning action of the bristles of roller brushes, apply correspondingly to the circumferential pads and bristles of cleaning belts.
  • the features specified in the subclaims with reference to claim 1 can be correspondingly transferred to the floor cleaning machine according to claim 11 and also lead here to advantageous refinements with the same advantages as are obtained with floor cleaning machines having roller brushes.
  • the entire cleaning units are expediently suspended from the chassis in an oscillating manner.
  • a frame in which the deflection rollers are mounted is guided in horizontal, transverse guides in the chassis.
  • a separate drive motor is preferably provided on each frame, which drives the oscillating movements of the frame of the cleaning unit.
  • the cleaning units or the roller brushes can additionally perform an oscillating pivoting movement about a vertical pivot axis.
  • a pivot bearing with a vertical bearing is expediently provided for each brush or cleaning unit Swivel axis provided, which is slidably mounted in a horizontal guide in the chassis. Pivotal movement and horizontal translational movement are expediently coupled to one another by forcing both movements from the same drive.
  • FIG. 1 shows the top view of a floor cleaning machine according to the invention designed as a polishing machine with two roller brushes with the covering removed
  • FIG. 2 shows the top view of a floor cleaning machine according to the invention with two cleaning units each comprising two deflection rollers and a rotating pad.
  • the front wheel 2 is mounted in bearing blocks 3 fixedly mounted on the base plate; the two rear wheels 4, on the other hand, are mounted in steering brackets 5, which are articulated on the base plate so as to be pivotable about a vertical axis 6.
  • a rectangular cutout 10 is provided in the base plate.
  • an electric motor 11 is built on the base plate.
  • the energy required for its operation is provided by three accumulators 12, which are also built on the base plate.
  • the drive shaft 13 is coupled to the drive of the electric motor 11 and is mounted in the two bearing blocks 14 built on the base plate.
  • the drive shaft 13 is coupled to the brush shaft 8 via a belt drive which comprises a toothed belt 15 which rotates around a pulley which is fixedly connected to the drive shaft 13 and to the brush shaft 8.
  • the roller brushes 9 are connected to the brush shaft 8 in a rotationally fixed but axially displaceable manner, for which purpose the brush shaft on the one hand and the cores of the roller brushes on the other hand each have corresponding multi-groove profiles.
  • crankshaft 19 is driven by the drive shaft 13 via a bevel gear 21, so that the crankshaft and the drive shaft have a fixed speed ratio to one another.
  • the crank pins of the crankshaft 19 are arranged offset by 180 ° with respect to one another, so that the two roller brushes 9 are displaced in opposite, oscillating movements on the brush shaft 8.
  • the floor cleaning machine shown in FIG. 2 differs from that according to FIG Fig. 1 essentially in that instead of two roller brushes two cleaning units 22 are provided, each of which comprises two deflecting rollers 23, 24 and a cleaning belt 25 rotating around them.
  • the rear deflection rollers 23 are rotatably but axially displaceably guided on the rear deflection roller shaft 26, as was described in connection with the roller brushes according to FIG. 1; the rear deflection rollers 23 are thus driven by the drive motor 11.
  • the link rings 16 are also firmly connected to them, as was described in connection with FIG. 1.
  • the front deflection rollers 24 are rotatably and axially displaceably mounted on the common front deflection roller shaft 27. They have the same dimensions as the rear deflection rollers 23. They are each connected to them via a coupling rod 28 in such a way that they follow the movement of the rear deflection rollers in their axial direction.
  • the ends of each coupling rod 28 are placed on the outer ring of roller bearings, the inner ring of which is firmly connected to the outer end face of the respective deflecting roller.
  • the cutout 10 in the base plate 1 is enlarged in accordance with the larger dimension of the cleaning units 22.
  • a projection carries the front bearing block 20 of the crankshaft 19 and the middle bearing block 29 for the front deflecting roller shaft 27.
  • the ends of the front deflecting roller shaft 27 are supported in the two outer bearing blocks 30.
  • the cleaning belt 25, of which the upper run has been omitted to clarify the structure of the cleaning units in the right cleaning unit, is designed as a pad known in the prior art.
  • the structure of the floor cleaning machine according to FIG. 2 corresponds to that of the machine shown in FIG. 1, so that reference can be made to the corresponding explanations and explanations.
