Definitions

  • the present invention relates generally to the treatment of continuous surfaces, and more particularly to the treatment of large-area continuous surfaces. Still more speciffically the invention relates to a method of treating largearea continuous surfaces, and to an apparatus for carrying out the method.
  • the present invention aims to overcome the disadvantages existing in the art.
  • the present invention has an an object to provide an improved method of treating continuous large-area surfaces.
  • a further object of the invention is to provide an apparatus for carrying out the novel method
  • one feature of my invention resides in a method of treating continuous surfaces according to which I first subject successive surface portions to a cleaning treatment, establish an evacuated volume of space contiguous with each freshly cleaned surface portion while I subject the next successive surface portion to the cleaning treatment, and applying a protective coating to the respective freshly cleaned surface portion within the evacuated volume of space.
  • My apparatus comprises a cleaning device which will be described in more detail subsequently, and one or more containers having an open side facing and fluid-tightly contacting the surface being treated, these containers being evacuated.
  • the purpose of such evacuation is two-fold, namely on the one hand it allows the apparatus to adhere to the surface which is being treated, even if the surface is underwater, and on the other hand the fact that the space contiguous with a respective surface portion undergoing treatment is evacuated, provides for improved efficiency in coating.
  • the vapor pressure existing in the evacuated space is so low that a very rapid drying effect is obtained which if desired, or if necessary, can be further improved by the use of drying means, such as infrared radiators or other drying devices.
  • drying means such as infrared radiators or other drying devices.
  • the surface-or rather the surface portionbeing treated has imparted to it an elevated temperature and this, in conjunction with the fact that the protective coating material is usually heated to substantially C. at high pressure, further aids in rapid hardening of the applied layer of coating.
  • FIG. 1 is a fragmentary partly sectioned side elevational view illustrating an apparatus according to the present invention
  • FIG. 2 is a plan view of the apparatus of FIG. 1;
  • FIG. 3 is a detail view, on an enlarged scale, of the apparatus shown in FIGS. 1 and 2.
  • the apparatus comprises two cleaning devices 1 and 2. These are located at opposite ends of the apparatus and in this embodiment the apparatus can move in opposite directions with the respectively leading cleaning device 1 or 2 being used for effecting cleaning or successive surface portions in the path of the apparatus.
  • the apparatus can move in opposite directions with the respectively leading cleaning device 1 or 2 being used for effecting cleaning or successive surface portions in the path of the apparatus.
  • it is possible to provide only a single clean device.
  • FIG. 1 shows that the cleaning device 1, which is thus representative of both of the cleaning devices, comprises a high pressure spray conduit 3 which is fed with water under high pressure, and guide baffles 4 and 5 which extend forwardly from the conduit 3 and engage the surface S which is to be cleaned.
  • the cleaning device 1 which is thus representative of both of the cleaning devices, comprises a high pressure spray conduit 3 which is fed with water under high pressure, and guide baffles 4 and 5 which extend forwardly from the conduit 3 and engage the surface S which is to be cleaned.
  • Water under high pressure, or another suitable cleaning fluid is ejected from the conduit 3 of the respective cleaning device against a respective surface portion of the surface S, and serves to clean such surface portion.
  • sealing cylinders 6 and 7 Located intermediate the cleaning devices 1 and 2, as most clearly shown in FIG. 2, are sealing cylinders 6 and 7 which contact the surface S and roll along the same when the apparatus is in use.
  • the rollers 6 and 7 are driven, for instance via an oil motor 8.
  • the pinion gear 9 of the motor 8 cams with a gear wheel 10 which is mounted on the shaft 11 which latter in turn is rigid with the associated cylinder 6 or 7.
  • each shaft 11 further carries at opposite axial ends of the respective cylinder 6 or 7 two profiled rollers 12 around which there is trained an endless belt 13.
  • These belts are located at opposite lateral sides of the apparatus, as evident from FIG. 2.
  • the outer circumference of each of the rollers 12 is provided with a guide groove and the belts 13 are each provided with a projection received in the guide groove so as to locate each belt in predeter mined position with respect to associated rollers 12 and to prevent it from axial shifting relative to these rollers.
  • a portion 14 of each belt 13 extends axially beyond the respective rollers 12 and inwardly towards the singleor, as in the illustrated embodiment, the several-evacuable containers 15, 16, 17, 18, 19 and 20.
  • each endless belt 13 cooperates with a stationary sealing means 21 provided on the evacuable containers, aridadditionally with a sealing strip 49 which is also secured to the evacua-ble containers.
  • the material of the sealing means 21 and the sealing strip 49 can of course be chosen so as to be compatible with the material of the respective endless belt 13, or at least the portion 14 thereof, in the sense of obtaining minimum friction and thereby a long service life of the thusrovided seal. It is emphasized that if the surface S has uneven portions, this will not adversely affect the justdescribed sealing arrangement because such uneven portions will act only upon the outwardly directed major surface of the respective belt 13 which passes over them. No strain is exerted upon the sealing arrangement per se.
  • the evacuable containers 15-20 each have an open side facing the surface S to be treated. They may be of very different cross-sectional configurations, for instance in the illustrated embodiment they are of trapezoidal cross section. Strips 22 of rubber or synthetic plastic elastomeric material connect the adjacent containers to one another, that is the container 15 to the container 16, the container 16 to the container 17, and so on, so that the adjacent containers are articulately secured to one another.
  • the containers 15, 16, 17, 18 and 19 are each provided with shafts 23 (two of which are shown) which extend transversely to the elongation of the apparatus, that is transversely to the direction of movement of the apparatus.
  • the shafts 23 turnably carry supporting plates 24 which in turn are provided with supporting rollers 25.
  • the upper and lower stringer of each belt 13 are supported by the rollers 25 and the latter press the lower stringer 13a against the surface S which is to be treated.
  • the endless belt 13 together with the cylinders 6 and 7 constitute a sealing frame which assures that the containers 15-20-once evacuatedcan be maintained in evacuated condition.
  • the shaft 23 it is emphasized that while these extend across the entire width and laterally beyond the respective containers 15-19, it is also possible to provide only short shaft sections extending laterally from opposite sides of the respective containers, and also to modify the roller arrangement by providing the supporting plates 24 with more than two supporting rollers.
  • FIG. 2 shows that a plurality of evacuating conduits 26, 27, 28, 29, 30 and 31 are each associated with one of the containers 15-20. All of the conduits 26-31 communicate with an exhaust conduit 32 which, in the illustrated embodiment, is composed of a plurality of elasticfor example of corrugatedconduit sections or hose sections each of which has its opposite ends fluid-tightly connected with a tubular connector whose interior not only communicates with the respectively associated sections, but also with the interior of the respective conduits 26-31, or rather with the interior of that particular one of the conduits with which it is associated.
  • the tubular connectors are identified with reference numerals 33, 34, 35, 36, 37 and 38 respectively and, as shown in FIG. 2, each communicate with one of the conduits 26-31.
  • FIG. 2 shows that one such possibility resides in the provision of a pair of cylinder-and-piston arrangements 39 and 40, preferably of the double-acting type, of which the arrangement 39 is associated with the containers 15 and 16 and the arrangement 40 is associated with the containers 19 and 26.
  • These arrangements 39 and 40 permit selection of the direction of movement of the apparatus during its operation.
  • a curved connecting portion 42 connects the terminal section of the exhaust conduit 32 with an injection nozzle 43 to which water or another liquid is supplied under high pressure through the inlet 44 in the direction of the arrow.
  • This arrangement operates on the well known ejector principle in that the stream of water under pressure which passes through the nozzle 43 creates a suction, aspirating air from the interior of the containers 15-20 and evacuating the same.
  • FIG. 1 shows that the containers 15-20 may be provided in their interior with drying means alone, with an applicator device in conjunction with drying means or, and this is not particularly illustrated, with an applicator device by itself.
  • the container 15 which is closest to the cleaning device 1 is provided only with a drying device 45 in form of an infrared radiator or the like.
  • the container 20, which is directly adjacent the cylinder 7, is provided with a similar drying device.
  • the container 16, which is arranged subsequent to the container 15, that is which is downstream of the container 15 if the apparatus in FIG. 1 moves towards the left, is provided with a similar drying device 46 and additionally with an applicator device 47 for applying the coating material to the surface S.
  • the container 17 is provided with a drying device 48 analogous to the devices 45 and 46.
  • Container 18 is provided with a drying device (not illustrated) similar to the one in container 17, and container 19 is outfitted in the same manner as container 16, namely with a drying device similar to the one identified with reference numeral 46 in FIG. I, and with an applicator device similar to the one identified with reference numeral 47 in FIG. 1.
  • the apparatus is intended to be capable of performing its intended function with equal facility regardless of whether it moves towards the left-hand in FIG. 1, or towards the right hand side. For this reason it is essentially a mirror-symmetrical construction.
  • the illustrated device is exemplary only and it is possible, for example, to utilize only a single or two of the containers.
  • a single container may contain the devices 46 and 47 shown in conjunction with the container 16 in FIG. 1.
  • two containers are used, then the leading one which is directly adjacent the respective sealing cylinder 6 or 7,
  • the container 15 may be either outfitted in the same manner as the container 15, that is with the drier 45, whereas the next one may be outfitted in the same manner as the container 16 in FIG. 1, while the leading container may be outfitted analogously to container 16 in FIG. 1 and the trailing one or next following one may be outfitted in the same manner as the container 17 in FIG.1.
  • the construction according to the present invention as well as the method according to the invention, are characterized by great versatility, and by the fact that they are capable of treating large surface areas rapidly and thoroughly, particularly with respect to the application of the protective coating.
  • the apparatus according to the invention will be lifted in suitable manner so that it will be juxtaposed with the surface to be treated.
  • a crane or other lifting device can be utilized, and this may be located on the structure having the surface which is to be treated, or it may be located spaced from the structure, for instance on a dock if the structure is a ship.
  • Other possibilities include the use of holding magnets which are tiltably mounted and whose contacting of the surface to be treated-and current supply if they are electromagnets-can be controlled in dependence upon pressure conditions in the sense that the magnets are caused to grip the surface to be treated in the event that the vacuum in the various containers should collapse and in order under such circumstances to prevent the apparatus from falling off the surface S.
  • a method of treating upright surfaces comprising the first step of cleaning a portion of an upright surface; the second step of juxtaposing an open side of an evacuable container in seal-tight relationship with the thus cleaned surface portion; the third step of evacuating said container so that the same adheres to and is suspended on said surface; the fourth step of applying a coating to said cleaned surface portion through said open side of the evacuated container; and the fifth step of freshly cleaning an adjacent portion of said surface contemporaneously with at least one of said second through fourth steps.
