Definitions
- the present invention relates to a plant for treating floors.
- the invention is particularly concerned with cleaning floors, but also other treatment processes, such as coating with liquid care products or other treatment liquids.
- the invention is directed to a system which on the one hand has a motor-driven device, which is referred to below as a mobile device and carries out the actual treatment, and on the other hand has a base station which is used to regenerate the mobile device at certain intervals.
- the mobile device thus moves in a motor-driven manner over the floor area to be treated and returns to the base station at certain intervals in order to be regenerated.
- the present invention is based on the technical problem of specifying a technically improved system of this type.
- the invention relates to a system in which the base station has a motor-driven transport device which is designed to transport the mobile device for regeneration into the base station and to transport it out of the base station.
- the invention is also directed to a method for wiping floors.
- the principle on which the invention is based is therefore to equip the base station with a motorized device for transporting the mobile device in and out, although the mobile device itself is motor-driven.
- the base station according to the invention is provided with its own motor mechanism, the transport device.
- the mobile device can thus be brought into a specific position without having to take into account the structural design of the base station and the structural design of the mobile device and its drive itself that the mobile device is in the suitable position with the aid of its own drive must be able to reach.
- the transport device of the base station according to the invention can also lift the mobile device, for which the drive will not be able in many cases.
- the transport device in the base station can, if desired or required, apply relatively large forces which the motor drive of the mobile device, which is supplied, for example, by an electric battery or the like, does not, or only with a generous design which is otherwise not necessary this drive, can muster.
- the mobile device preferably has a wiping textile with which it wipes the floor for cleaning or for other reasons.
- the regeneration then preferably includes cleaning the wiping cloth or exchanging the wiping cloth for a cleaned or a new wiping cloth.
- the term "wiping textile" is to be understood in a very general manner and can include all possible fiber-based flat products with which a floor can be wiped. So it can be nonwovens, rags, fur-like or paper-like textiles and others.
- the base station contains an inclined plane on which the regeneration of the mobile device takes place and to which the mobile device is therefore brought by the transport device. The inclined plane can ensure better accessibility to the underside of the mobile device and thus make it easier to clean or replace a wiping cloth or to regenerate it in some other way.
- the motor-driven transport device of the base station contains at least one, preferably two levers, which are designed to grip the mobile device. The gripped mobile device is then pulled or lifted into the base station by the levers.
- the one or two levers are preferably provided with a mechanism which latches on appropriately designed receptacles of the mobile device when it is gripped.
- the latching should preferably be released again in the further course of the transport of the mobile device into the base station, the levers being able to serve to guide the transport process in the base station even after the latching has been released.
- the locking mechanism can be a spring-mounted pin coupling.
- the coupling pins can have a corresponding
- the coupling pins are provided on the levers and the receptacle with the
- the spring-mounted coupling pins can by another mechanical device in the base station or by an inclined plane on the device of the base station with the
- the base station preferably cleans the mobile device by passing it over a squeezing roller, through which the cleaning liquid still contained in a wiping textile or previously applied for cleaning the wiping textile is pressed out of the wiping textile, so that the associated dirt is also removed. This also applies to the squeezing out of treatment liquids that are not used for cleaning.
- the squeezing roller is pressed onto the mobile device with a preferably adjustable pressure.
- the squeezing roller can be mounted eccentrically or the guide devices for the mobile device can be adjustable relative to the squeezing roller.
- cleaning fluid is used which is recycled in the base station, that is to say has already been squeezed out at a previous point in time.
- the base station can have a filter, in particular a continuous filter, for the cleaning liquid.
- the new moistening can serve, on the one hand, to repeat and improve cleaning by pressing out again. Secondly, it may be desirable to moisten the wiping textile a little or to actually wet it before wiping the floor again. It is particularly preferred that the cleaning system can also carry out a two-stage or multi-stage wiping process, in that the mobile device first wipes relatively wet and then absorbs the liquid still on the floor by wiping rather dry.
- the base station can be provided with an additional device which enables a wiping text to be replaced by changing it from one
- Adhesive fastener (so-called Velcro or similar) is removed from the mobile device. Then use a new or cleaned wiping cloth continued to work, which is reapplied to the adhesive fastener. In this embodiment, this is done automatically by the base station.
- the degree of soiling of the floor to be cleaned, the wiping cloth used, the cleaning liquid in the base station and / or the filter for the cleaning liquid can be measured and monitored, which is preferably done optically or optoelectronically.
- the invention is also directed to the mobile device for wiping flat surfaces, in which the drive, when the device is moved by the drive, lies within a path width covered by the wiping surface.
- the drive is therefore arranged within a path width covered by the wiping.
- the drive does not interfere outside the web width detected during wiping, for example if wiping is to be carried out just along a bottom edge.
- the invention enables the wiping surface to come into a relatively small distance from this edge or to wipe without such a distance, because the drive, for example a wheel running as a drive part between the track width detected by the wiping and the bottom edge, within the detected Web width is arranged.
- the drive will lie above the surface to be wiped.
- the drive is preferably arranged above the wiping surface, but in principle it can also be arranged in front of or behind the wiping surface in the direction of movement, as long as it remains in the web width.
- the invention thus also offers the possibility of providing a relatively wide wiping area in relation to the size of the device, which is also essentially determined by the drive.
- the wiper device according to the invention preferably has narrow and long external dimensions in the sense of a projection onto the surface to be wiped, that is to say a significantly larger extension in one direction than in a second direction perpendicular thereto.
- the numerical ratio of the dimensions of the longest and the narrowest side is preferably at least 2: 1, more preferably at least 2.5: 1 and in the best case at least 3: 1.
- a preferred basic form of the device in the projection onto the surface to be wiped is a narrow one long rectangle. Narrow, long external dimensions on the one hand allow a relatively large web width and on the other hand not too large overall
- the device can be used very flexibly when driving through narrow passages or when wiping narrow corners.
- the named external dimensions of the device are caused by the wiping surface, that is to say the wiping surface forms the edges of the device in the plane of the surface to be wiped or at least essentially corresponds to these.
- the wiping surface that is to say an exchangeable wiping cover, protrudes on one or more sides over other parts of the device and thus on the one hand enables particularly good wiping along floor edges and on the other hand forms a protective abutting edge.
- other abutting edges can also be provided, which are not formed by the wiping surface itself.
- abutting edges equipped with sensory properties can also be provided in order to indicate an automatic control of the wiping device to an impact on an obstacle and thus to trigger corresponding control reactions.
- the wiper device preferably moves forward in such a way that one and the same long side points forward during a wiping run. It is then wiped with the maximum possible web width and, on the other hand, the dirt pushed together during cleaning is pushed in front of it. This preferably also applies during and after cornering, so that the wiper device leaves no wiping strips in corners or curves.
- the wiping device can first drive with the long side mentioned as far as the stop on the opposite edge, then move back, turn 90 ° in the direction of the future direction of travel (so that the long side described now follows in the future direction of travel front)), in this rotated position, drive along the edge to the corner again and then continue in the new direction from the corner.
- a journey with the front long side in the corner would be converted into a drive with the same front long side out of the corner in the new direction of movement.
- the wiping surface moves in an oscillating manner with respect to the rest of the device, for example oscillates or circles in one or also in two (horizontal or vertical) directions with respect to a base of the device. This means that the mechanical impact on the ground can be increased without having to run over the same track several times.
- a further embodiment of the invention provides for the wiping device to be equipped with a wiping surface not only on one side but on two opposite sides. The device can then be turned by the intervention of a user or automatically in order to be able to continue with the second wiping surface.
- the wiping surface is continuous, that is, forms a coherent surface in the mathematical sense.
- it is preferably in the sense of the direction of movement behind those touching the ground Parts of the drive closed so that there are no traces of wheels, drive belts and the like.
- wheels or belts are therefore preferably provided within the wiping surface or in the sense of the direction of movement in front of it or a part of it.
- the invention is also directed to an improved drive for moving the device over a surface, which has a flywheel that is movable and motor-driven relative to a base of the device and is designed to drive the device by moving the flywheel relative to the base, by at In some of these movements, static friction holding the device on the surface is overcome by inertia of the centrifugal mass and not in another part of these movements, the movements of the centrifugal mass relative to the base as a whole being iterative.
- Mass inertial forces are used, which arise from relative movements between a flywheel and a base that forms the fixed component of the device. In certain phases, these inertial forces result in a static friction holding the device on the surface on which it is to move being overcome. In other phases, however, the inertia forces should not overcome static friction. In the following, we shall speak in simplified terms of movement phases and phases of detention. Depending on the reference system, inertial forces are transferred to the base by the movements of the flywheel, which partly move it and partly let it adhere to the surface. In other words, the movements of the flywheel lead to a reaction of the base because the overall system tries to correspond to the conservation of momentum. However, the conservation of momentum is disturbed by the friction between the device and the surface.
- the base remains on the surface in the sticking phases, while it moves on the surface in the movement phases. It is preferably a sliding or sliding movement, with corresponding static friction in the grip phases in wheel bearings or between wheel surfaces and the surface, it could also be a rolling movement during the movement phases.
- the wiper device only touches the surface to be wiped with the wiping surface because no wheels, drive belts or the like have to be used.
- flywheel is part of the device and should not be used up by the drive concept according to the invention. Although an energy coupling will be necessary to generate the movement, the flywheel mass should be preserved as such in contrast to recoil drives such as rocket drives or jet drives.
- the invention thus enables sliding or rolling locomotion without coupling between the drive and the transport surface. This can be of interest, for example, if a positive or non-positive connection with the transport surface is difficult to produce, for example on very smooth surfaces, or if contact between the drive and the surface is not desired in the cleaning device according to the invention.
- an energy store in particular a mechanical spring
- the acceleration phase provided for overcoming the static friction can be facilitated by the energy store with correspondingly large forces, and the motor drive itself can only be used for feedback.
- the drive could press the flywheel against the spring force and thereby tension the spring, whereupon the drive is switched off and the spring is allowed to accelerate the flywheel relatively violently.
- rotary movements between the flywheel and the base are also possible. Circular movements are preferred. Two cases are conceivable in the case of the rotary and in particular the circular movements, which in principle could also occur in a mixed manner.
- the actual conservation of momentum in the sense of the linear momentum i.e. in the sense of the centrifugal forces, can be exploited.
- the conservation of angular momentum can also be used, in which the base experiences an angular momentum when the angular momentum of the flywheel mass is changed. If the case of linear momentum conservation is in the foreground, the flywheel mass be arranged eccentrically with respect to the rotational movement.
- the flywheel is meant in the sense of the center of gravity and not necessarily in its physical form.
- an increased acceleration of the flywheel could be used in certain areas of the track, for example in the case of non-circular tracks such as sun or planetary tracks
- the angular momentum acting on the base for example when the direction of a concentric rotation of the flywheel changed.
- a "jerk" of the base can be created, which overcomes the static friction for a certain movement phase.
- the movement phases that is to say the “jerk movements of the base” generated by the inertial masses
- the static friction is also overcome in the context of "regressions”, which, however, lead to a less backward movement than the desired forward movement.
- the flywheel drive could briefly overcome the static friction limit even with inertial forces that are basically acting in the wrong direction. If the static friction limit in the desired direction is overcome for a longer time or at a higher speed, this does not in principle stand in the way of locomotion according to the invention.
- the device can become heavier or lighter at times and possibly also in places, in other words, they can be pressed onto the surface by appropriate inertial forces or relieved of gravity.
- inertial forces that remain constant in terms of amount in the movement phases can cause the device to slide due to components opposing the gravitational force, and stick in phases of sticking due to components acting parallel to the gravitational force.
- the flywheels are preferably gimbally suspended from the base. This can serve to tilt the planes of rotation in the sense just described. Furthermore, in contrast to a fixed, unchangeable tilting, a corresponding adjustment of the cardanic suspensions can also be used to adjust the size of the static friction between the device and the surface and also to compensate for any directional dependencies of this static friction, for example in the case of aligned wiping textiles.
- the gimbal is preferably adjusted by motor and can in particular also take place automatically, in that the device tests the start of the movement phase to a certain extent and adjusts itself automatically to an optimal propulsion for given rotational movements by adapting the tilting.
- the device moves step by step above the surface with translatory individual steps when the device is aimed for straight movement.
- an angular momentum component acting on the base is exploited in that one end of the device serves as an axis of rotation, to be precise, by "weighting” it by an angular momentum component acting on the base parallel to the surface.
- an opposite end of the device can serve as the axis of rotation and an oppositely directed and acting on the base angular momentum, i. H.
- a component perpendicular to the surface can be used for a corresponding second step.
- the device would, for example, move alternately step-by-step with a right and a left side and thereby rotate about the other side.
- the angular momentum components can be generated either by tilting rotating gyroscopes or - less preferably - by accelerating or braking such gyroscopes.
- the device according to the invention does not necessarily have to be free from other drive or steering influences.
- it may also be desirable to provide an operator with an influence on the movement for example by applying a style for steering or also for supporting the movement.
- a motorized mop with style would make it easier for a cleaning person to slide the mop over the surface to be cleaned on the one hand, and on the other hand the mop could in addition, it is much heavier and therefore more effective in terms of cleaning effect than a conventional manually operated mop.
- an autonomous and automatically moving cleaning device with the flywheel drive described is preferred.

- Fig. 1 shows a schematic diagram for a flywheel drive according to the invention.
- 1 denotes a wiping device for wet wiping and thus cleaning floors in the household or in other interiors. It is shown in Fig. 1 as a simple cuboid.
- the wiper device 1 rests on a floor 2 and faces it with a wiping surface 3.
- a flywheel 4 which is only symbolically shown here, is provided, which is horizontally movably supported in a manner not shown. In the present case, it is driven by a drive motor 6 via a lever linkage 5, which is also only symbolic, against the force of a spring 7.
- the drive motor 6 thus tensions the spring 7 up to a certain point, whereupon a trigger mechanism releases the flywheel 4 from the force decouples the drive motor or unlocks the drive motor 6.
- the spring 7 can then accelerate the flywheel 4 relatively quickly, namely to the left in Fig. 1.
- there is a reaction force on the base ie the remaining wiper device 1, which accelerates the wiper device 1 to the right against the static friction between the wiping surface 3 and the floor 2 in the sense of FIG. 1.
- the movement of the flywheel 4 by the drive motor 6 could be used as a flywheel movement for the movement phase; the wiper device 1 then moves gradually to the left.
- the spring 7 is used here only as an energy store in order to bring the flywheel 4 back into the starting position for a new acceleration by the drive motor 6.
- the spring 7 represents energy storage devices of any type, which can also be electrical (capacitors), for example. It should be clarified that the energy for the return of the movement does not necessarily have to come from the drive motor 6.
- FIG. 2 shows a very similar model case, in which the same reference numerals as in FIG. 1 are used. The difference between the mechanism shown in FIG. 2 and that from FIG. 1 is the tilting of the movement path of the flywheel 4 against the horizontal by the angle.
- FIGS. 1 and 2 Another alternative to the functions shown in FIGS. 1 and 2 is to have the flywheel 4 and the spring 7 as a linear oscillator perform a natural oscillation by the drive motor 6, preferably in a state close to resonance.
- the desired adhesion phases and sliding movement phases already result due to the different influence of the static friction in the two reversal points of this vibration.
- the flywheel 4 could, for example, be braked relatively hard at one of the two reversal points, for example by an elastic wall (not shown) or another comparatively harder spring. There would then be correspondingly large retarding forces with which the static friction can be overcome.
- Fig. 3 illustrates another embodiment of a flywheel drive.
- flywheels 4a and 4b are provided, which are mounted eccentrically and rotatably.
- the axes of rotation of this rotary movement are designated by 8a and 8b.
- the two flywheels 4a and 4b rotate synchronously and in opposite directions. It can be seen that the planes of rotation and the axes of rotation 8a and 8b are inclined.
- the synchronous rotary movements of the flywheels 4a and 4b are simultaneously at the top (shown in FIG. 3) and bottom apex. At the top vertex, the centrifugal forces add up with a gravitational vertical component and a horizontal component.
- the horizontal components are labeled Fi and the vertical components are labeled F 2 .
- the inclined centrifugal force on the other hand, with Fz.
- the centrifugal forces can thus move the wiper device, designated 9 here, to the right by a certain sliding distance.
- the centrifugal forces also add up, but here they increase the resulting force from the gravity of the wiper device 9 and the vertical component of the centrifugal forces, which is essential with respect to static friction. Due to the opposite rotation of the two centrifugal masses 4a and 4b, the inertial forces in the remaining area of the respective tracks at least partially compensate, so that the static friction is not exceeded there either. Rather, the sliding phase only affects a certain temporal environment of the state from FIG. 3.
- the wiping device 9 can be achieved in these lowest vertices just remain due to static friction.
- the iterative sliding phases can thus be achieved by a continuous circular movement of the flywheels.
- Fig. 4 shows the standstill phase.
- the centrifugal masses are at the lowest apex of the respective circular movement.
- FIG. 5 shows a further wiper device 10 with a flywheel drive, which is shown only symbolically here, and which corresponds to the explanations for FIGS. 3 and 4.
- An electronic control 11 with a microprocessor for program control of the wiper device, a memory, an evaluation device for position and acceleration sensors or for collision sensors, which are arranged on the side edges of the wiper device 10 but are not shown, and an electronics for monitoring the with are symbolically drawn 12 designated power electronics, which controls the charging and discharging processes of electric accumulators and the motor drives of the flywheels 4a and 4b.
- the electrotechnical details of such a control are readily clear to the person skilled in the art. The focus of the invention is rather on the functioning of the flywheel drive.
- the wiping device 10 from FIG. 5 also shows not only a wiping textile 13 on its underside, the underside of which forms the wiping surface currently being used, but also a further wiping textile 14 on the top that is not used in the state shown.
- the wiping device 10 can thus either be used by the user by hand or by a base station, which will be explained later, in order to be able to continue wiping with the second wiping textile 14 if the other wiping textile is dirty or used up.
- the wiper device shown here has a numerical ratio of the edges in the projection onto the floor of approximately over 3: 1. This makes it easy to clean tight spaces and, on the other hand, to achieve effective web widths on large areas.
- FIG. 6 illustrates a top view of a gimbal mounting of the flywheels 4a and 4b from FIGS. 3 to 5.
- 9 and 10 is the "fixed" base the corresponding wiper device indicated.
- the line of sight is from above to the floor level.
- a first axis of rotation 15 holds a first gimbal ring 16, to which a second axis of rotation 17 is attached, which is rotated by 90 ° to the first axis of rotation 15.
- the second axis of rotation 17 holds a second cardiac ring 18, on which the flywheel 4a or 4b is rotatably mounted about the axis of rotation 8a to 8b.
- the motor drive of the flywheel mass 4a or 4b is preferably carried out by electric motors provided in the cardan bearings or else by flexible shafts which are brought in from motors fixedly attached to the base 9, 10, but are not shown in the drawing.
- the gimbal bearing with the axes 15 and 17 can be adjusted by servomotors, also not shown, via lever linkages with levers attached to the rings 16, 18 on the axes of rotation 15 and 17, respectively.
- the wiping device 9, 10 can adapt to different friction conditions between the respective wiping textiles or other wiping surfaces and different floors by adjusting the rotational speeds and the rotational planes, even if these are direction-dependent .
- the electronic control 11 can detect when the wiper device 9, 10 is moving and, for example, by increasing the tilting of the rotation planes, strive for a state in which the static friction is overcome in phases and still exists in phases.
- the wiper devices 9 and 10 can move in any horizontal direction as a result of the gimbal mounting.
- the wiping device 9, 10 can also be rotated about a vertical axis by, for example, reducing the centrifugal forces of the flywheels at maximum gravity-reducing Vertical component are opposite or the overlays with the gravitation on both be different are.
- any overlays from rotary and translatory movements can also be achieved.
- angular momentum For an angular momentum drive one would have to protrude in Fig. 3 and the following figures instead of the eccentrically suspended centrifugal masses gyroscope with a concentric center of gravity.
- Their angular momentum could, for example, be essentially horizontal and, due to jerky changes compared to the original position, could act as an angular momentum acting on the base with a vertical direction. This vertical angular momentum could turn part of the wiping device. If at the same time an angular momentum component with a horizontal direction provides weight to one end, this could serve as an axis of rotation for a pivoting movement of the wiper device. Subsequently, a further step could be taken with the direction of rotation reversed and the weight applied to the corresponding other end of the wiper device, so that here too there is an iterative means of locomotion.
- the drives described are all arranged inside and above the wiping surface.
- Fig. 7 shows a further rotary movement of a flywheel 19.
- the flywheel 19 is mounted eccentrically in a planet gear 20, the
- the planet gear 20 runs on a fixed sun gear 22, with the center of the planet gear one
- Circular path describes, the focus 21, however, a dashed line
- FIG. 8 shows another example of a basic possibility of a flywheel drive.
- a wiper device is symbolically indicated at 25 in plan view.
- a bearing 26 is provided therein, in which an eccentric crescent-shaped flywheel 27 is rotatably guided.
- a movement of the flywheel 27 can be achieved via a lever linkage (double crank with joint) 28 via a motor connected to point 29. This movement is uneven at a uniform engine speed and accordingly likewise leads to an inertial drive of the wiper device 25 with sliding phases and sticking phases.
- Fig. 9 shows an alternative drive, so no embodiment for a flywheel drive.
- a wheel drive is provided within a wiper device 30 and is arranged within the wiper surface (corresponding to the wiper device 30 in the plan view from FIG. 9), in which two wheels 31 and 32 can be driven independently of one another and rotated relative to the wiper device 30.
- the wheels are shown in two different positions, but there are two wheels in total.
- the wiping device 30 can be transported with its wiping surface over the floor, any direction of movement and also rotations of the wiping device 30 being caused by speed differences between the wheels 31 and 32 and by motorized adjustment of the angle of the axes of rotation of the wheels 31 and 32 relative to the wiping device 30 around their own axis. It must be ensured that the frictional connection between the wheels 31 and 32 and the floor in relation to the sliding friction of the wiping surface on it is sufficiently high.
- FIG. 9 illustrates in particular that an arrangement within the wiping surface is also possible with this drive, and any traces on the floor which may be caused by the wheels 31 and 32 can be wiped away regardless of the direction of movement.
- the wiping area is namely a closed area around the drive.
- the wiping surface in particular in connection with the wheel drive, provision can be made for the wiping surface to rotate in relation to the drive or to vibrate in another way in order to increase the mechanical cleaning effect.
- a flywheel can also be used for this.
- the flywheel drives can of course be supplemented accordingly in the various examples.
- FIG. 10 shows a front view of a wiping device 33 which has a wiping textile 34 which projects beyond the lateral edge of the actual wiping device 33.
- This wiping textile 34 serves as edge protection and furthermore limits the dimensions of the wiping device 33 in the projection onto the floor. This allows particularly efficient wiping along wall edges without the risk of damage due to the wiping device 33 bumping.
- the wiping devices according to the invention can, of course, also have corresponding impact protection edges, independently of wiping textiles, which can also take over senor tasks to inform the already mentioned electronic control 11 of a collision with an obstacle.
- FIG. 11 shows a basic diagram of one shown in the viewing direction of FIG. 10
- the distance between squeezing rollers 36 and 37 or between squeezing rollers 38 and 37 is adjustable so that the force with which the wiping textile 34 is squeezed out can be determined in a suitable manner.
- the squeezing rollers 38 press on the wiper device 33 itself and the squeezing rollers 36 on the protruding edges of the wiping cloth 34, the squeezing rollers 37 forming a counter bearing.
- the expressed cleaning liquid flows downwards in the manner indicated.
- FIG. 12 shows a somewhat more specific training example for the base station, which is designated 39 here.
- the wiper device 33 from FIG. 10 or, for example, also the wiper device 10 from FIG. 5 or the wiper device 9 from FIG. 3 can be moved into the position shown on the left in FIG. 12 with the aid of its own drive. There they are gripped by two levers 40, which can be tilted by a motor in the manner shown.
- resiliently mounted pins which are explained in more detail below, are engaged behind undercuts in the grooves 41 which can be seen in FIG. 12 on the respective front regions of the longitudinal sides of the wiper device 33.
- the levers 40 can grip the wiper device 33 and lift it in a tilting manner, as a result of which the front end of the wiper device 33 is guided between squeezing rollers 42 and 43.
- the squeezing rollers 42 and 43 pull the wiper device 33 further upward at an angle, the insertion pins disengaging from the catches and instead continuing to run in the grooves 41 as a guide.
- the wiper device 33 is transported in this way to an inclined plane 44, the squeezing rollers 42 and 43 expressing residual moisture in the wiper textile 34.
- the cleaning liquid running off flows through a continuous filter 45 into a
- the transport of the wiper device 33 is supported by a further transport roller 49.
- a fresh water tank 50 is provided, which contains clear fresh water for rinsing, for example for a final wipe cleaning, and can accordingly be connected to the nozzle 48 in a manner not shown.
- the cleaning system can perform a multiple, initially wet and then drier wiping in the manner already described.
- the oblique movement of the wiper device 33 on the level 44 enables the wiper device 33 to be easily transported into the base station 39 with the aid of the motor-driven lever 40.
- the underside and thus the wipe textile 34 of the wiper device 33 are accessible and space for the components described below Level 44 created.
- the hydraulic unit on the flow filter 45, dirty water tank 46 and nozzle 48 and fresh water tank 50 can also be completely removed as a module.
- the distances between the rollers 42 and 49 with respect to the rollers 43 can also be adjusted in order to ensure optimum pressing and a sufficient frictional connection for the transport.
- the residual moisture in the cleaning textile 34 can also be adjusted.
- the setting can be made, for example, by eccentrics in the axis of rotation bearings.
- FIG. 13 illustrates the latching mechanism already mentioned for gripping the wiper device 33 by the levers 40.
- On the lower left one of the two levers 40 can be seen, which carries at its end a pin 52 which is spring-mounted by a spring 51.
- FIG. 13 is reversed in relation to FIG. 12.
- the groove 41 already mentioned has an undercut 53 in its initial region, that is to say in the vicinity of its right end in FIG. 12 and the left end in FIG. 13, into which the pin 52 can snap.
- the Locking is facilitated by a bevel 54 at the beginning of the groove 41.
- the disengagement from the undercut can take place either by means of a similar incline with the aid of the forces exerted by the squeezing rollers 42 and 43 or with the aid of a further mechanical disengagement, which is indicated here by the motor-driven fork 55. This can grip the pin 52 and pull it outward from the undercut 53. The pin 52 then slides along the groove 41 as a guide.
- a base station can also be designed to provide a wiper device with two wiping textiles (cf. 5) to rotate by 180 °.
- FIG. 14 shows schematically that the base station 39 can also be used to replace the wiping text 34 in a second department, if necessary.
- FIG. 14 shows how the wiping textile 34 is pulled off two rollers 56 and 57 by Velcro fasteners (not shown in more detail) on the lower surface of the wiping device 33 and placed in a container 58. 15, conversely, shows how the or a fresh wiping textile 34 can be removed from a container 60 by a pressure roller 59 and applied to the adhesive closure.
- the wiping device 33 is transported in an oblique direction, comparable to the explanations for FIG. 12.
- a lever mechanism corresponding to the explanations for FIG. 12 can also be used.
- the various motorized movement steps in the base station 39 can be controlled by light barriers or similar sensors. As soon as the wiper device 33 is gripped, the typical current profiles of the electric motors involved can also be used in order to draw conclusions about the respective movement phases. Furthermore, as already mentioned earlier, optical evaluations of the degree of soiling of the floor, the wiping cloth, the cleaning liquid in the wiping textile or also in the container 46, the degree of soiling of the filter 45 and the like can be used.
- the base station 39 can be programmable to certain
- Wiping textiles can also contain transponders that are read in the base station.
- the electronic control 11 of the wiping device which can possibly also be reprogrammed by an electronic control of the base station, can control the wiping device (in whatever specific design), taking into account known data relating to room dimensions and floor characteristics, or data determined during previous trips. The user can also specify the rooms to be cleaned and thus call up known data records or enter essential characteristics of such rooms.
- the wiping device can carry out an automatic position determination, for example by known odometric methods, in that the movement distances and directions are determined and thus the current positions are determined. A position can of course also be determined in a different way, for example using laser measuring systems.
- the wiping runs are preferably S-shaped with preferably the same leading longitudinal edge. This means that large areas can be cleaned with just a few trips and little overlap of the web widths recorded. The movement already described, with the front edge always remaining the same, also prevents dirt strips from being deposited in curves or corners.
