Definitions

  • Car conveyors employed in car washing machines are usually mechanical and they are based on the use of a chain or equivalent, which conveys the car at a constant speed from one washing phase to the other.
  • Conveyors of this kind are complex and expensive, in addition to which it has been found in practice that they are easily damaged and that they expose the workers to danger.
  • Endeavours have therefore been made to introduce simpler and less dangerous conveyors.
  • One such is a tube which is flattened under the wheel so that it is fully closed and into which a liquid under pressure is supplied.
  • transverse ridges On the upper wall of the tube transverse ridges have been provided, which under the car wheel are urged into a corresponding grove in the lower wall of the tube, thereby sealing the tube to be closed at this point.
  • the ratio of the propagating force and lifting force is low.
  • a car conveyor according to the invention is characterized in that the tube has been formed of hollow, wedge-like sections which have been placed one in the other and attached to each other by their outer edges so that in the tube chambers are formed, and that at the narrower end of the wedge-shaped part there is an aperture for conducting the pressure medium from one chamber to another.
  • a conveyor of this kind has, above all, the advantage of reliability in service and that as a pressure medium also a gas, such as compressed air, may be used.
  • the ratio of the propulsive force and the lifting force is also substantially higher than in any structures of prior art.
  • the parts constituting the tube are conical. It has found to be particularly advantageous if the parts constituting the tube are oblique cones, the apertures at their narrower end lying closer to the lower surface of the conveyor than to its upper surface. Each such chamber forms a stop of appropriate shape, which efficiently pushes the car wheel and at the same time the entire car forwardly.
  • one may also form the tube of membranes which have been attached to each other and to the lower surface of the conveyor so that they constitute chambers.
  • the chambers are wedge-shaped and such that with their aid the most efficient car-transporting force possible is obtained.
  • FIG. I shows wedge-like parts, of which the elastic tube has been formed
  • FIG. 2 presents the elastic tube, with the wedge-like parts mutually joined
  • FIG. 3 shows a car conveyor in elevational view and partly in section
  • FIG. 4 shows the section along the line lV-IV in FIG. 3,
  • FIG. 5 shows the section along the line VV in FIG.
  • FIG. 6 shows the car conveyor at the point where the car wheel resides, as seen from the side and sectioned
  • FIG. 7 shows schematically the car conveyor and the car, viewed from above
  • FIG. 8 presents another embodiment in schematical presentation
  • FIG. 9 shows the wedge-like part according to a third embodiment.
  • each part 4 is composed of a conical portion 11 and a cylindrical portion 12. The free outer edge of these, 5, attaches tightly to the juncture 13 of the conical and cylindrical portions of the next part.
  • an aperture 15 opening to one side has been formed for introduction of pressure medium into the tube 2 in the part 14 .
  • the narrower end of the exit part 16 has been shaped as a downwardly opening exit port 17. All parts except this exit part 16 have at their narrow end an aperture 7.
  • FIG. 2 these parts 16, 4 and 14 have been joined, whereby in the interior of each part a separate chamber 6 is formed.
  • the pressure medium proceeds from the introduction part 14 towards the exit part 16, passing from the chamber 6 through the aperture 7 into the corresponding chamber of the next part.
  • FIG. 3 a car conveyor having a plurality of zones has been shown.
  • the pressure medium is introduced through the aperture 15 at the initial end of the zones, and it escapes through the apertures 17 at the ultimate ends of the zones.
  • FIG. 4 there is seen the supply duct 18, through which the pressure medium is conducted to the zones, and the exit duct 19, through which the pressure medium escapes.
  • a protective carpet 10 has been placed upon the elastic tube 2, and topmost there are guiding borders 20, which keep the car wheel centred upon the conveyor.
  • FIG. 6 the situation is depicted in which the car wheel 3 has flattened the tube 2 to full closure.
  • Pressure medium is then introduced through the supply aperture 15 at the initial end of the zone into the chamber 6, whereby the pressure of the pressure medium urges the wheel in forward direction.
  • pressure medium passes through the aperture 7 into the chamber formed by the next wedge-like part, which pushes the wheel further, thus transporting the car forwardly.
  • the pressure medium proceeds from one chamber into the next as the wheel 3 moves forward, until it emerges through the exit port 17 of the exit part at the end of the zone. Simultaneously, however, the next zone has already commenced to move the car forwardly.
  • the car conveyor has been formed of one zone only.
  • the pump 21 then supplies pressure medium to the initial end of the conveyor.
  • FIG. 8 there are several zones, and the pump 21 supplies pressure medium to the initial end of each zone.
  • Valves 22 are used to regulate the amount of pressure medium going to each individual zone.
  • FIG. 9 an alternative design has been presented for forming the tube 2.
  • the conical and cylindrical parts one may use membranes 9, of which the upper sides and sides of the chambers 6 are formed.
  • the lower surface 8 of the conveyor serves as lower part of the tube, the tube 2 composed of the membranes 9 being tightly pressed against it.
  • Car conveyor in particular one intended for a car washing machine, which moves the car with the aid of stops pushing against the wheels on one side at least and which consists of an elastic tube flattening under the car wheel to full closure, into which tube a fluid pressure medium is conducted so that the stop moving the car wheel is formed of the inflating tube, wherein the improvement comprises that the tube has been composed of hollow wedge-like parts, which have been placed one into the other and joined at their outer rims so that within the tube chambers are formed, and that at the narrower end of the wedge-shaped part there is an aperture for conducting the pressure medium from one chamber to the other.
  • Car conveyor according to claim 1 characterized in that the parts constituting the tube are conical.
  • Car conveyor according to claim 1 characterized in that the parts constituting the tube are oblique cones, the apertures at their narrower end lying closer to the lower surface of the conveyor than to its upper surface.
  • Car conveyor according to claim 1 characterized in that the tube has been composed of membranes attached to each other and to the lower surface of the conveyor so as to form chambers.
  • Car conveyor according to claim 1 characterized in that the tube has been divided into at least two consecutive zones, to each of which pressure medium can be separately conducted.
  • Car conveyor according to claim 1 characterized in that upon the tube a protective carpet has been placed.
