Definitions

  • the invention relates to a method for cleaning surfaces, in particular Traffic areas with a heterogeneous, preferably paved surface, by means of a self-picking pneumatic sweeper, the one or several suction shafts are assigned, which with a broom as well as side brushes interacting the dirt in the area of a receiving Move the suction shaft and a device for performing the method.
  • OS 16 58 419 provides information on this by introducing a suction head which has devices which deflect the pressure of the suction flow and its direction. In this case, however, an air jet is generated from a nozzle, which exerts a loosening pressure on the surface to be cleaned, is deflected there in a parallel direction, reaches a suction nozzle and is thereby deflected back into the suction head.
  • DE OS 24 46 728 discloses a self-picking sweeper which has a suction shaft and a suction head attached to it. The suction head has an attachment on its underside that runs flat and parallel to the surface to be cleaned. The approach is flexible and can be adjusted in its position.
  • OS 25 03 694 provides a hint for the gentle cleaning of soiled areas. Even if from another area of application, this solution gives the expert a hint to clean soiled areas, which can be traffic areas, without destroying their heterogeneous structure.
  • the document discloses a sweeper, if only for carpets, the sweeper roller is mounted in the body of a sweeper.
  • the device is moved on rollers which are covered with drive belts, the middle part of the run wrapping around the sweeping roller and thereby causing it to rotate.
  • the rotation of the sweeper roller running clockwise or anti-clockwise depending on the direction of movement of the sweeper, loosens the dirt from the surface to be cleaned and throws it tangentially into the sweeper. From there it can be removed by opening the collector of the sweeper.
  • the principle of the solution shown shows a careful cleaning of the traffic area, but does not make a mandatory solution, since the arrangement in a suction device and its practical operation is not recognizable.
  • EP 19 192 now discloses the design of a suction head which allows the air of the suction flow to be sucked horizontally into the suction head in three directions, but the disadvantage of the known technique which is shown is not eliminated, since the suction flow is probably to the side and behind and in front of the suction head seen in the direction of travel of the sweeping device, can be sucked in, but then deflected and unrestrained into a vertical suction flow, the effective range of which is projected approximately perpendicularly onto the traffic area.
  • the solution according to EP 367 276 has the same disadvantage.
  • the disclosed configuration of the suction nozzle of a motor-driven hand-held vacuum cleaner indicates that the intake air is drawn in horizontally in the region of the nozzle and is deflected in such a way that the effect of the vertical vector on the influence on the traffic area is minimized.
  • the solution shown is unsuitable to be included as a functional component in a sweeper.
  • the invention has for its object a method for cleaning surfaces, especially of traffic areas, with a heterogeneous, preferably paved Surface, by means of a self-receiving, pneumatically working Sweeper to which one or more suction shafts are assigned, which with Broom brush or side brush interacting, sweeping in the area of a receiving suction shaft and a device for carrying it out of the procedure to create an intensive cleaning of the traffic areas is possible without destroying their structure.
  • the object is achieved by a method with which the sweepings are moved by means of a horizontally directed suction flow into the suction mouthpiece of the suction shaft, guided in the suction mouthpiece over a horizontal support, received above the support, and with the rising vertical suction flow deflected from the horizontal direction is detected and transported into the dirt hopper.
  • the horizontal support is arranged on the lower suction opening of the suction head opening against the traffic area, between the traffic area and the entry area of the air of the vertical suction flow, the traffic area being shielded from the vertical suction flow and the only above the suction nozzles directed horizontal sweep across the pavement, the debris sucks into the suction shaft.
  • the suction mouthpiece carries a closure part at its lower suction opening, which closes the suction mouthpiece against vertical entry of a suction flow and its action on the structure of the traffic area and has lateral openings through which the suction flow directs horizontally , directed parallel to the traffic area, picks up the dirt.
  • a sensible embodiment is formed so that the closure part is designed as a support, on the inside of which the debris sucked into the suction nozzle in the horizontal suction stream is deposited and entrained by the suction stream that rises vertically above it in the suction shaft and reaches the garbage container.
  • the invention is expediently designed if the support on the sides on which the suction mouthpiece cooperates, lateral suction openings are formed, in the direction of the traffic surface, has bevels which ensure an effective absorption of the sweepings in the horizontal suction flow.
  • An advantageous embodiment of the invention can thus be made available that the closure part encloses the suction mouthpiece and in its horizontal support has an opening which extends largely transversely to the working direction and into which a rotating, roller-shaped sweeping brush is arranged, which sweeps the sweepings through the opening in moved the interior of the suction head onto the support in the area of the vertically rising suction flow.
  • the invention is expediently further developed if the sweeping brush closes the opening as far as possible against the action of the vertical current, so that its parts are not detached.
  • the method and the device advantageously allow surfaces to be cleaned whose structure is heterogeneous. This applies in particular to traffic areas whose ceiling is not made of concrete or bituminous coverings, but has a paved surface. Paving of various types, both as a cuboid and as a mosaic pavement, can be found in a large part of older cities and also in districts that have retained their historical character or were subsequently designed for tourist reasons.
  • sweepers with the device equipped according to the invention can now drive over such surfaces in a suction and sweeping manner without the disadvantageous consequences, as indicated in the prior art, without damaging the structure of the paving. Because the suction head is closed on its lower face, the vertically sucking stream of pneumatically operating sweepers has lost its adverse effect on the structure of the paving. The pad now closes the suction head in the direction of the traffic area that has been passed.
  • the suction flow is deflected in a horizontal direction by the closing effect of the support, whereby the horizontal direction is not a component of the vertical suction flow, but the suction flow with its full effect, now enters the suction head horizontally through the side openings, sweeps over the horizontal support and then deflects into a closed vertical suction stream that transports the sweepings placed in the horizontal direction vertically from the support in the rectified suction flow into the sweepings container.
  • the occlusive effect of the support means that only a horizontally acting suction stream comes into contact parallel to the surface to be cleaned and therefore no longer injures the joints of the paving even when the cleaning operation is in progress. The dirt is no longer removed, but drawn into the suction head over the paved surface.
  • the cleaning effect is intensified by the fact that the roller-shaped broom rotates, picks up the debris in the course of rotation in the tangential direction, transports it through the opening onto the support part and presents it to the vertical suction flow which acts here unchecked. It is apparent to the person skilled in the art that a significant solution has been found to arrange the method and the device according to the invention on the suction mouthpieces of sweepers already in operation and to retrofit the machines in this way. No inventive effort is required to make this invention detachable and removable, so that the sweeper can be used again for robust sweeping operation if required. It is also easily possible, in an advantageous embodiment of the invention, to minimize or completely stop the suction air flow and to use the sweeping brush in a rotating manner to clean the traffic area.
  • Fig. 1 shows the inventive design of the pad 9 in its arrangement in a suction mouthpiece 1 of a pneumatic sweeper.
  • the edition 9 is attached in the lower region of the suction mouthpiece 1 and closes the Area of the suction mouthpiece 1, which is inclined towards the traffic area 14, completely.
  • the support 9 is arranged directly in front of the opening of the suction shaft 2 and shields the vertical suction jet from acting on the Traffic area to be cleaned 14. Because the suction jet is no longer vertical can rise from the lower opening of the suction nozzle 1, none adverse erosion of the surface to be cleaned 14.
  • the side surfaces of the suction mouthpiece 1 are arranged by Openings 7; 8 in the area of the side edges of the support 9 and the flaps 15 open.
  • the openings are 7; 8 nozzle-shaped and can be expanded by opening the flaps 15.
  • the directional arrows 4 show the direction and the course of the Suction current on the side openings 7; 8 in the suction nozzle 1 horizontal entry.
  • This horizontal direction allows a sweep the plaster surface 14 when the suction flow passes over the suction mouthpiece 1, without violating their structure, because the vertical suction flow through the one below Edition 9 is kept away from the pavement surface 14.
  • the invention avoids any erosion of the traffic area 14, regardless of whether it is a paved traffic area 14 or one closed ceiling interrupted by parting or false joints.
  • FIG. 2 shows in a Top view the possibility of enlarging the openings 7, 8, so that their dimension be designed efficiently from the area of slot-shaped nozzles can. Furthermore, the view specifically shows the horizontal feed area 4 of the Suction flow and its course over the traffic area 14.
  • the representation according to Fig. 3 shows a similar design and view of the suction mouthpiece 1 as in Fig. 2, but here the suction mouthpiece 1 is a roller broom 3 downstream.
  • the roller broom 3 is under the sweeper in a known manner arranged and has a direction of rotation opposite to the direction of travel of the sweeper 6.
  • the broom 3 brushes continuously in one operation its inclination, the debris in the area of the suction nozzle 1, is there the rear side of the suction mouthpiece 1 is opened so that the broom 3 in a formed tangentially to its surface, the debris into the suction nozzle 1 can transport. Due to the trailing arrangement of the broom 3 is collected by the sweepings in the area of the suction mouthpiece 1 Sweeping swath, led to the rear of the suction nozzle 1 and now sucked in in a known manner.
  • this configuration represents that by shielding the lower surface of the suction nozzle 1 through the pad 9 of the horizontally directed suction flow and thus its component acting in the area of the broom 3 with the broom 3 corresponds very effectively and is now gentle on only one horizontal plane sweeping and sucking the traffic surface is cleaned. Because the components of the suction flow also makes sense on the front and on the side surfaces of the suction mouthpiece 1 act, the amount of horizontal to be recorded Sweepings advantageous over the entire intake area of the suction mouthpiece 1 distributed.
  • Fig. 4 shows the view slightly offset from Fig. 3 as a side view. The representation shows that the debris from all sides horizontally in the suction nozzle 1 retracted and over the pad 9 in a vertical direction in the suction shaft 2 is pulled.
  • FIG. 5 shows the suction mouthpiece 1 in a similar position as Fig. 3.
  • the roller broom 3 in the direction of travel of the sweeper upstream of the suction mouthpiece 1.
  • the roller broom 3 now places the swath from the transverse transport direction in front of the opened suction opening 11. It makes sense the opening 11 is enlarged by lifting the flap 15 and thus adapted to the amount of dust from the sweepings.
  • the flaps 15 are operated in different ways to partially to change the inlet cross-sections 11 for the horizontal air flow.
  • Fig. 6 presents the training of FIG. 5 in a side view.
  • FIG. 7 shows a variation of the basic idea of the Solution according to the invention in a side view in section.
  • Edition 9 is here formed as a closure part of the suction mouthpiece 1 and encloses its periphery Completely. To carry out the cleaning process is here in the horizontal Edition 9 of the closure part an opening 12 is arranged, which is against the traffic area 14 extends.
  • the opening 12 probably leaves the action of the vertical Suction flow, however, the following can be determined here with this variation:
  • a sweeping brush 13 it can be extremely gentle
  • the traffic area 14 can be cleaned by making the suction flow strong throttled or brought to a complete standstill.
  • it is Debris for exposure to the vertical suction flow for transport into the debris container placed in the suction shaft 2.
  • this type of application not limited to cleaning without suction or its reduction of traffic areas. Even if the full intensity of the suction flow this embodiment can be used.
  • the rotation of the sweeping brush 13 still lifts the debris to the inside the edition 9, supported by the full suction flow that is now through the opening 12 could enter the suction mouthpiece 1.
  • the opening works 12 upstream sweeping brush 13 as a brake for the speed of the suction flow.
  • the sweepings are countered at full speed by the suction flow the bristles of the sweeping brush 13 are pulled and moved in a rotating manner.
  • the suction flow becomes tired in the density of the bristles of the sweeping brush 13 and becomes thereby slowed down, so that here the horizontal component with full force of the suction flow acts, but in the area of the sweeping brush 13 in the transition into his vertical direction the intensity slowed down and the adverse erosion effect of the vertical suction flow is eliminated.
