  • For the treatment in particular cleaning or washing of mats, such as floor mats or similar textile fabrics, it is desirable to increase the throughput of such devices while at the same time lowering the costs for the treatment or cleaning. It is particularly desirable to provide an at least partially and, if possible, fully automated device or system, by means of which a large number of textile fabrics, in particular mats or carpets, can be treated, in particular cleaned, with high quality in a comparatively short time.

Similar to what was described above for the mechanical cleaning station 80, the wet cleaning station 90 also has a feed opening and a discharge opening in the housing 91 in order to enable a defined feed and discharge for the textile fabrics.
  • a spray device 94 with a plurality of nozzles 92 arranged, for example, on a common carrier 96 is shown.
  • a cleaning fluid 95 can be applied to the nozzles.
  • the nozzles 92 are offset transversely to the conveying direction F or arranged at a distance from one another. The distance between the nozzles 92 is determined by the emission characteristics of the nozzles.
  • the nozzles 92 spray a comparatively wide-ranging jet onto the textile fabric 5.
  • the individual jets fan out onto the textile fabric 5 and form an effective area 98 there.
  • the respective active area 98 of each nozzle 92 is the area on the textile Flat structure 5, which is wetted by a nozzle 92 with liquid or is pressurized.
  • the arrangement of the nozzles 92 is selected as a function of their emission characteristics in such a way that, transversely to the conveying direction, a plurality of active areas 98 adjoin one another at least seamlessly or are arranged so that they overlap at least in some areas. In this way, the entire mat 6 or the textile fabric 5 can be completely wetted with a cleaning fluid 95 or subjected to a high-pressure jet.
  • the nozzles 92 or the spray device 94 can be pivoted with respect to a pivot axis S on the housing 91 of the wet cleaning station 90 .
  • the spray angle can be changed as required in order to achieve an optimal cleaning result.
  • the spraying device 94 has two nozzles 92, which are also arranged in a number of ways transversely to the conveying direction F. However, their radiation characteristics differ from those of the nozzles 92, which are shown in 29 are shown.
  • the nozzles 92 in 30 and 31 The spraying device 94 shown has an effective area 98 that is significantly smaller in terms of surface area.
  • the nozzles 92 can, for example, direct a jet that is concentrated onto the fabric 5 or onto the mat 6 . A significantly higher cleaning effect can be achieved.
  • the individual nozzles 92 or the spray device 94 are movably mounted in the housing 91 so that the entire surface of the flat structure 5 can be treated with the cleaning fluid 95 .
  • the individual nozzles 92 can be movement-coupled to one another via a common carrier 96, for example. In this respect it is only necessary to move the carrier 96, on which the nozzles 92 are arranged, for example transversely to the conveying direction F back and forth. With a continuous back and forth movement of the spray device 94 results in the simultaneous transport of the fabric 5 along the conveying direction F over the Time an approximately V-shaped effective range. In the longitudinal direction, however, the individual legs of the V-shaped effective area are arranged in an overlapping manner.
  • a further movable mounting of several nozzles 92 is shown. These can be moved continuously and comparatively slowly in a direction transverse to the conveying direction. The nozzles 92 are then reset abruptly, so that the individual active areas 98 are irradiated or irradiated at an angle, as it were, according to the conveying speed of the mats 6 or the textile fabrics 5 .
  • a further embodiment of a spray device 94 is shown, in which the individual nozzles 92 are arranged so as to be rotatable relative to the housing 91.
  • circular effective areas 98 result, which are successively acted upon by the cleaning fluid 95 .
  • the circles or thickness of the circular rings, which correspond to the effective area 98, are adapted to the conveying speed of the mats 6 or fabrics 5 in such a way that the individual effective areas 98, which are achieved as a result of a circular movement of the nozzles 92 in relation to the fabric 5, in the conveying direction F and/or overlap at least in regions transversely thereto, so that the entire surface of the fabric 5, and therefore of the mat 6, can be exposed to the cleaning fluid 95.
  • Figure 33 is shown in a side view that the spray device 94 is preferably arranged below the conveying path 31 and that the nozzles 92 are aligned obliquely upwards, typically with a directional component opposite to the conveying direction F on the mat pile 8 of a mat 6 pointing downwards.
  • the nozzles 92 can be pivoted and adjustable with respect to a pivot axis S. In this way, the application angle or the angle of impact on the mats 6 or fabric 5 can be adjusted as needed or optimized.
  • Excess or running down cleaning fluid 95 is collected in the collecting tank 99 and can be fed to a water and washing media treatment 22 .
  • the spray device 94 with its nozzles 92 to be directed onto the outer radius of a deflection device 70 of the conveyor device 30 .
  • the mass web 8 can be spread open due to this outward curvature in order to improve a cleaning effect.
  • FIG 35 another exemplary embodiment of a wet cleaning station 90 with a housing 91 is shown. Inside the housing 91 there is a cleaning basin 93 which is at least partially filled with a cleaning fluid.
  • the conveyor device 30 extends in a meandering manner through the cleaning tank 93 with a plurality of deflection devices 70, 70', 70". Multiple turns in the area of the deflection devices 70, 70', 70" result in an additional mechanical force and/or cleaning effect on the fabrics 5 or on the mats 6.
  • the embodiment of Figure 36 also shows the embodiment of FIG 31 similar wet cleaning station 90.
  • at least one or two of the deflection devices 70 are movably mounted in the housing 91.

  • a nozzle 92 is directed towards the outside of a deflection device 70 within the cleaning basin 93 .
  • the mat pile 8 can be spread open, so that an increased cleaning effect can also be achieved here.
