Definitions
- the invention relates to a method and a device for cleaning the underside of footwear and the wheels of shopping carts, wheelchairs, strollers and the like in the entrance area of highly frequented public facilities, such as sales facilities, administration and business buildings, medical stations or other buildings with public traffic and defined purity requirements.
- a support frame made up of parallel bars or strips is arranged in a frame into which rows of bristles standing upright are clamped or glued.
- devices of this type have a certain overall height, they are embedded in specially designed floor recesses in the entrance area of the building, the brushes on the top being approximately flush with the surface.
- the cleaning brushes are fixed, free-running or motor-driven. Since the relatively rigid bristles can also penetrate depressions in the sole profile, they clean more intensively than mats.
- DE 4447498 AI suggests one shoe sole cleaning device based on rotating brush belts, the cleaning brushes of which are automatically cleaned by attacking counter-brushes during operation.
- the device includes a large number of parallel, motor-driven cleaning brushes that extend transversely to the walking direction of the pedestrians. To remove stubborn dirt in a targeted manner, the brush belts are guided past fixed counter brushes or rotating brush wheels outside the tread plane.
- the proposed measure undoubtedly increases the cleaning effect and extends the maintenance intervals.
- a device for cleaning wheels is known from WO 95/23715.
- This device comprises a platform which can be driven over a ramp and has a trough-shaped depression.
- a cleaning device made of brush segments is arranged on the base of the depression, while the sloping side surfaces have opposite pairs of rollers. At least one roller can be driven by a motor in order to set the wheels in rotation during the cleaning process.
- the retail chains strive for a high customer throughput.
- the above-mentioned thorough cleaning devices are, however, only time-consuming to pass. They limit customer throughput and ultimately ultimately sales.
- the invention was therefore based on the object of providing a method and a device which do not have the abovementioned disadvantages and in particular have a long-lasting high cleaning action even under adverse weather conditions and intensive use.
- the advantage of a long-lasting high cleaning effect is achieved by using a cleaning mat that is endless and rotates between at least two deflection rollers.
- the mat acts at least partially as a step surface and absorbs solid and liquid contaminants, while in a spaced-apart backflow
- This section can be removed by mechanical, pneumatic, thermal or other suitable treatment of the mat.
- a cleaning device with a circumferential cleaning mat is embedded in such a way that a tread surface is created flush with the surrounding floor or slightly lowered, while the dirty mat is treated on the opposite side of the floor opening facing away from the tread surface for the purpose of cleaning it .
- the cleaning devices include devices for removing the applied dirt and those for expelling the liquid absorbed by the mat.
- Mechanical, hydraulic and / or pneumatic actuating means act on the mat to remove the dirt and dirty water adhering to the surface.
- the former includes, for example, dirt-wiping doctor blades, cleaning brushes
- the latter can be brush belts running back and forth or rotating roller brushes, tapping or vibrating devices, suction nozzles and the deflecting rollers leading in a meandering or zigzag shape.
- Cleaning using liquid can be carried out by means of liquid jets emerging continuously or temporarily from nozzles or by contacting a liquid bath in such a way that at least the mat pile is temporarily immersed in the liquid.
- Water serves as the cleaning liquid wedge, to which detergents or other additives can be mixed.
- Pneumatic actuating means are to be understood as nozzle arrangements which blow dirt and moisture out of the carpet pile by means of compressed air.
- the simultaneous exposure to the web with ultrasonic vibrations can promote the process of dirt and moisture separation.
- the moisture remaining in the mat after completion of these cleaning stations is then expelled thermally by heat flow, radiation or exposure to microwaves.
- pile cleaning on an electrostatic basis is also possible.
- the dust particles are extracted from the mat, which is electrostatically charged in a suitable manner, when it passes through a counter electrode.
- the cleaned and dried mat can finally be guided past a device, for example a rotating brush roller, which straightens and loosens the pressed-on fibers again.
- a device for example a rotating brush roller, which straightens and loosens the pressed-on fibers again.
- one or more tensioning rollers are arranged at a suitable point, for example in the area of the cleaned and dried mat.
- At least one of the deflection rollers or guide rollers arranged in the underfloor area is designed as a tensioning device.
- the entire weight of the people and cars is transferred to the cleaning device via the mat. It is therefore necessary to support the mat in the area of the tread so that it does not sag or become overloaded.
- the cleaning mat rotates at a barely perceptible speed in the majority of applications, in the simplest case it can slide over a support plate which is locked in the frame or surface in the entire area of the tread. The forces exerted by stepping on are then diverted into the ground via this plate and the device frame.
- the edges thereof are equipped with an additional insert which has a profile or perforation and is operatively connected to drive elements on at least one of the deflection rollers.
- An alternative embodiment of such a support system which is preferred according to the invention makes it possible, however, to combine the function of supporting the circumferential mat in the area of the step surface with the function of its transport in an advantageous manner.
- This is achieved according to the invention with the aid of a belt conveyor.
- a transport belt runs around between the mentioned deflection rollers. It is equipped with a non-slip surface on its surface.
- the conveyor belt and cleaning mat run in parallel in the area of the deflecting foils and the upper run.
- the mat is supported on the belt due to the action of the tensioning device and the loads that occur. Thanks to the non-slip covering, the belt simultaneously transfers its feed to the mat and drives it.
- the conveyor belt is a link belt made of articulated interlocking plate links.
- the belt consists of parallel slats arranged perpendicular to the conveying direction, which are fastened on toothed belts or roller chains.
- the circumferential belt strap can slide completely or in sections on or in guide rails.
- the band can also be a reinforced elastomer band, which is releasably connected to the cleaning mat in the form of a Velcro fastener or non-releasably by gluing or the like. Cleaning mat and belt strap merge to form a functional unit.
- the belt band absorbs the feed and tensile forces, and the attached or flocked pile layer absorbs dirt particles and moisture.
- the mediating adhesive layer for anchoring the pile serves at the same time to cushion and insulate sound emissions from the drive and cleaning units in the underfloor area.
- At least one of the deflection rollers preferably that in the direction of rotation in front of the tread, is driven. If the feed force is to be transmitted by frictional engagement, then at least the drive roller has one non-slip coating, e.g. a rubber jacket.
- the belt webbing can of course also run at a suitable point via an additional drive roller or a drive pinion.
- the cleaning device is electronically controlled and equipped with internal and external sensors.
- the integrated control device has programs for summer and winter operation as well as a time control for busy and light traffic times.
- the internal sensors measure dirt and moisture in the mat leaving the step surface. Their output signals control the feed rate and the intensity of cleaning and drying the mat.
- Dirt and dirty water accumulating in the cleaning device can either be collected in collecting containers or discharged via a drain on the floor.
- the strips on the longitudinal edges simultaneously hold the mat edges on the conveyor belt and also serve as a guide for the wagon wheels.
- walk-on cover strips overlap or adjoin the deflecting area of the cleaning mat. In the former case, they are chamfered towards the mat to ensure easy opening and closing.
- the walk-on cover strips of the longitudinal and end faces form at least part of the cover that can be removed for maintenance purposes.
- the entire cleaning device is completely integrated in a frame and is inserted as a structural unit in a prepared, appropriately dimensioned floor opening in the entrance area of the building and fixed there.
- a preferred embodiment is based on the concept of modular construction. Components to be subdivided according to their function in the drive, deflection and cleaning unit can be combined with one another in any way and thus allow adaptation to the requirements of the most varied of applications. This leads to a universal applicability of the cleaning device according to the invention far beyond the area of the sales facilities.
- the cleaning device according to the invention has a practically unlimited absorption capacity, since again and again a cleaned and dried clean running mat is provided.
- the saturation of dirt and water that occurs with conventional mats does not occur even after a long period of operation and adverse weather conditions. Therefore, a constant and good cleaning effect is guaranteed for a long time. This ease of maintenance saves costs for the provision of personnel for cleaning or replacing the mats that are laid out.
- the mat Due to the at least approximately flush arrangement with the surrounding floor, the mat is also very easy to overcome for shopping trolleys, strollers, wheelchairs, buggies etc. and therefore does not represent a restriction of customer throughput even in highly frequented sales facilities that can only be entered with shopping trolleys.
- the invention is not limited to sales facilities. It can be used in front of or in any type of business building or other public facility with heavy traffic. Since cleaned and loosened cleaning mat is constantly supplied during traffic, it always gives off a pleasant appearance.
- the modular design allows great flexibility through retrofitting or retrofitting. Individual modules can be exchanged or supplemented with little effort.
- the invention In addition to preventing the entry of dirt and moisture, the invention also opens up a possibility for improving hygiene in rooms equipped with it.
- the circumferential mat is not only permanently adherent Get rid of dirt and moisture, but treat them further.
- Such further treatment can consist, on the one hand, of intensifying the cleaning effect by applying a detergent.
- the mat can be impregnated with a disinfectant liquid after the cleaning steps have been completed.
- a disinfectant liquid In medical facilities, such as hospitals, or in research and production facilities with high cleanliness requirements, this also makes it possible to reduce the entry of germs through the soles of shoes or the wheels of trolleys in addition to dirt.
- These agents can be applied in a manner known per se by means of rotating brushes or spray devices.
- the arrangement of the cleaning device is not limited to horizontal floors. It can also be integrated into a ramp for cars and wheelchairs.
- Equipping or linking the device with modern measuring, control and regulating devices allows a wide variety of driving styles. In this way, different modes can be specified for busy or light traffic periods, for summer or winter operation, etc.
- internal sensors allow operation depending on the actual level of dirt in the cleaning mat, while external sensors can be used to detect sudden weather fluctuations. kung (surprising strong thunderstorms or the like) can be reacted to immediately and before the mat is overloaded.

- the area of the cleaning mat (10) serving as a tread surface is lowered by up to 10 mm with respect to the surrounding floor (20).
- the rounded guardrails (30) on the side this results in a guide for the shopping trolleys.
- At the longitudinal ends are slightly wedge-shaped limiting strips (40) attached. They are intended to avoid the drawing in of coarse particles and to facilitate the entry and exit of the wagons. These slopes are equipped with an anti-slip surface (50) to increase grip on wet shoes and tires.
- the cleaning mat (10) is designed as an endless belt which rotates below the floor level between at least two deflection rollers (60) and (70), at least one of which is driven, at a speed of approximately two meters per hour. To convey the mat (10) and at the same time in the area of the tread
- the device has a support which is based on a circumferential webbing (90). and transport system, as shown schematically in Fig.2.
- FIG. 3 An embodiment of the support and transport system based on a chain link belt is shown in detail in FIG. 3.
- the deflection roller (60) located behind the tread surface (80) in the direction of transport is connected to a drive motor via a chain or gear transmission.
- the endless mat (10) lies on the slats (150) of the webbing (90) in the area of the upper run. This area forms the step surface (80) of the cleaning device according to the invention.
- the load applied by the customers entering the tread surface (80) of the device and the shopping cart is transferred from the cleaning mat (10) to the belt (90).
- the guide rails (120) on both sides prevent the chain links (130) from sagging by taking up the load and introducing them into the frame via supports (100).
- the former can be provided with an anti-slip covering (50).
- FIGS. 4 and 5 illustrate an embodiment of the support and transport system based on a plate link belt.
- the link belt (90) consists of plate links (150) made of metal, for example aluminum, or another suitable material, which are arranged in an articulated manner and engage in the articulated direction.
- the band (90) slides over a support plate (370) or bilateral guide rails (120) in order to absorb the impacts. As already mentioned, this prevents sagging of the tread surface (80) and also relieves the bearings of the deflection rollers (60), (70).
- the band (90) is guided in rails almost continuously during the entire circulation.
- the flat outer surface of the plate members in turn has an anti-slip covering (50) to increase the adhesion with the mat (10) lying thereon.
- the opposite inner surface is equipped with a web to increase the bending strength.
- the deflection rollers (60) and (70) are equipped on their jacket with a corresponding profiling, so that the webs of the belt members (150) engage in recesses in the deflection rollers and thus transmit the drive torque, as shown in FIG. 4 can be seen.
- the cleaning mat (10) which is sewn, hooked, glued or zipper-like to an endless web, is longer than the belt strap (90).
- the band (90) and mat (10) separate on the deflection roller (60) under the influence of the guide rail (160) or due to the effect of gravity. Detached and at a distance from the conveyor belt (90), the mat (10) passes through a number of treatment stations (170), (180), (190) for the purpose of cleaning and drying it, and at the latest on the deflection roller (70) to the belt belt ( 90) to be pressed.
- dirt and moisture sensors (200) and (210) check the degree of contamination and moisture penetration of the mat (10) leaving the tread surface (80).
- the output signals of these sensors (200) and (210) control the feed speed of the mat (10) and the intensity of cleaning and drying. The greater the contamination found, the higher the feed speed and the more intensive the cleaning. By increasing the feed rate, cleaned dry carpet is supplied more quickly.
- the mat (10) passes through a dirt wiping device in the form of a wiping plate and / or a roller brush (170) in a first treatment stage, which mechanically remove adhering dirt.
- the rotary movement of the roller brush is applied by a separate, preferably electric motor drive unit. Alternatively, it can also be generated from the feed movement thereof, with the cooperation of a roller that is in contact with mat (10) or belt (90).
- the dirty water carried on the surface and in cavities is removed.
- the mat (10) is pressed out in the nip of a calender (180).
- Remaining residual moisture is expelled in a subsequent heating stage (190).
- a warm air blower or a radiant heater serve as a source of thermal energy.
- the warm, moist air is released into the surroundings via ventilation slots (220).
- it has proven to be advantageous to recover the released moisture via a condensation device (230) and to supply it to a collecting container (240).
- a temperature sensor (250) controls the temperature in this area.
- a tensioning roller (270) is arranged at a suitable point, preferably in the area between the cleaning devices and the deflection roller (70).
- the tensioning system ensures that the mat (10) on the deflection rollers (60), (70) and in the area of the tread surface (80) lies tight on the conveyor belt and runs reliably through all treatment stations.
- Dirt and water can be collected in possible containers (240) and (280).
- a floor drain can drain dirt and water.
- Mat (10) and band (90) are detachable or, as sketched in Fig. 8, non-detachably connected to each other.
- a detachable connection which includes sewing, Velcro or hook / eye connections, makes it easier to replace a worn cleaning mat while maintaining the less stressed webbing.
- Such a cleaning sliding belt 500 made of a combination of three components is shown in detail in FIG. It comprises a pile layer (510), a carrier web (540) and a mediating adhesive layer (550).
- the pile (510) consists of a mesh fabric (530) that receives resistant bristles (520).
- the carrier web (540) transmits the drive torque and absorbs the tensile forces that occur.
- Mesh (530) and bristles (520) are anchored in the adhesive layer (550). It is elastic and sufficiently flexible to cushion the impacts and to compensate for the changing pressure and tensile loads on the pulleys. It also insulates sound emissions from the treatment stations. Flame retardants or other additives which influence the strip properties in the desired manner are incorporated in the adhesive layer (550).
- Band (500) slides in the area of the tread surface (80) over a support plate (370) which rests on cross members (380) and struts (390). The forces acting on entering and driving onto the tread surface (80) are introduced into the device frame via the support plate (370) and the cross members and struts (380) and (390) mentioned.
- the area of the support plate (370) acted upon by the belt has the lowest possible coefficient of friction.
- This can be achieved in a manner known per se by an appropriate surface treatment. This includes both friction-reducing coatings and useful structuring of the plate surface, in particular honeycomb-shaped arch structures. The latter simultaneously increase the section modulus against deflection.
- the cleaning sliding belt (500) loaded with dirt and / or moisture leaves the tread surface (80) via deflection roller (70) and first goes through an arrangement at different levels of fixed and loosely mounted rollers (320) ._The rollers (320) are arranged so that that the continuous belt (500) experiences a multiple deflection.
- rollers 320 are loosely supported. Under the action of a spring, which can also be a gas pressure spring, they press elastically against the continuous web (500) and tension it to compensate for changes in length due to temperature and humidity fluctuations. If necessary, they also have a dampening effect on load spikes in the drive system.
- Moisture and dirt sensors (200) and (210) downstream of the waizen section (320) check the degree of soiling and moisture penetration of the web (500) before entering the further treatment stations 170, 180, 190, 310, 330, 340, 450 and / or 460. Control their output signals, as already mentioned elsewhere, the intensity of the subsequent treatment and the feed speed of the web.
- the mat (500) passes through a suction device (310).
- a nozzle arrangement covering the entire web width which can be operated with a brushing / tapping device (330) or an ultrasound scanner. action can pull dirt and moisture out of the carpet.
- a magnetron can be arranged in the subsequent thermal treatment stage, which acts on the moist cleaning sliding belt 500 with microwaves.
- the dielectric medium water absorbs the incident radiation and evaporates. Appropriate shielding prevents unwanted radiation emissions.
- the tread surface (80) and boundary strips (30) and (40) are level with the surrounding floor. If necessary, they end flush with the carpet with the help of an elastic lip.
- the boundary strips (30) and (40) are parts of the cover. For maintenance and repair purposes, they are detachably or hingedly connected to the housing frame, whereby a gas pressure spring or a spindle motor can assist opening.
- FIG. 7 The embodiment shown in FIG. 7 is characterized in that the entire cleaning device can be folded out of the bottom opening.
- Your support frame is rotatably mounted in a bearing (420). This allows the cleaning device to be folded up as a whole for the purpose of emptying the collecting containers (240) and (280), for maintenance or repair purposes. This means that all device components are easily accessible.
- Gas pressure springs (400) or spindle motors in turn support the lifting movement.
- the concept of the modular construction preferred according to the invention is shown schematically in FIG.
- the entire device is modular, consisting of essentially three functionally different grain sizes. components - a drive module, a deflection module and one or more cleaning modules.
- the drive module receives the drive roller (60) and the drive unit including its control unit (350).
- the deflection module essentially consists of the deflection roller (70) and the tensioning device (320).
- the cleaning modules (630) comprise the treatment stations (170, 180, 190, 310, 330, 340, 450, 460) for removing the applied dirt and for expelling the absorbed liquid. Both modules with only a single cleaning unit are provided, as well as modules that combine two or more treatment steps that complement each other, such as tapping and vacuuming, brushing and vacuuming or drying and straightening or loosening the pile.
- Each module (610,620,630) is a self-contained unit and equipped with its own supply connections for the integrated treatment facilities. Of course, it also has all the elements of the support structure (support, struts, support plate, etc.).
- this can be the connection of a drive module (620) and a deflection module (610).
- a drive module 620
- a deflection module 610
- one or more are placed between these modules (610) and (620)
- An external moisture sensor (290) is connected to the cleaning device. This is located outside the building and reports, for example, a rain shower directly to the control device.
- the status of the device can be read off via a display and control element (300).
- This device (300) can also be used to enter the corresponding opening times of the supermarket, at which the device automatically switches on or off.
- the control element (300) can, for example, be permanently installed at the supermarket information desk. But it can also be portable. After programming or reading the status, the control element is separated from the cleaning device and stored in a safe place. A radio connection is also conceivable.
