Definitions

  • the invention relates to a method and a device for decontaminating objects with a waterproof surface, in particular coated pillows.
  • the system also includes an economically working equipment processing system.
  • the decontamination solution liquor is continuously circulated and prepared during the cleaning process.
  • the rinsing water is also returned to the decontamination boiler.
  • washing and rinsing in a single wet cabin results in a high degree of economy with little equipment Effort.
  • the repetition of the washing and rinsing processes and the change in position of the objects carried out ensures that the entire surface is subjected to a treatment and that no inaccessible support points are formed.
  • the subsequent drying in the drying cabin enables the objects to be available again immediately after the wet treatment.
  • the relative position of the objects is also changed several times during drying, so that no moisture remains at support points.
  • the change in position in the wet cabin is particularly advantageous when the objects are introduced into a turning basket which turns the objects into different relative positions and when the objects are sprayed with the washing liquid and the washing liquid through the turning basket.
  • a spray bar arrangement can be used for this purpose, which is moved over the turning basket.
  • An optimal change of position results when the objects are turned through 180 ° between two washing or rinsing processes. Depending on the application, however, smaller turning angles or intermediate positions would also be conceivable.
  • the objects are preferably also turned in a turning basket and blown through the turning basket with heated air.
  • the device according to the invention has a very simple structure and is therefore user and maintenance-friendly.
  • a treatment device for washing and rinsing the objects and a turning device for turning the objects are arranged in the wet cabin.
  • a drying cabin, which contains a drying device, is connected to the wet cabin.
  • a transport device is available, which ensures the transport of the objects through the wet cabin and through the drying cabin.
  • the treatment device for washing and rinsing is preferably a spray bar arrangement which is mounted so as to be displaceable transversely to the direction in which the objects are fed.
  • Cross can mean at right angles to the feed direction or at an angle to the feed direction.
  • arched movements would also be conceivable.
  • the advancement of the spray bar arrangement enables an intensive, linear treatment of the objects.
  • the detergent source and the detergent source are each connected to a separate spray bar arrangement.
  • the cleaning and rinsing takes place in separate runs immediately one after the other.
  • the exposure time of the decontamination solution can be chosen freely, as can the fresh water consumption.
  • a particularly high degree of rationalization results from the fact that the swiveling reversing basket is formed in the wet cabin with a receiving opening, at least by means of the transport device in a first operating position an object can be inserted into the turning basket and the same object can be carried out from the turning basket in a second operating position.
  • the reversing basket can be loaded and emptied automatically. This is made even easier by the fact that the reversing basket is formed by parallel longitudinal profiles which extend in the transport direction, the longitudinal profiles forming parallel basket planes, between which an object is held.
  • the transport device is a conveyor belt with a plurality of parallel individual belts or round profiles arranged offset to the longitudinal profiles, one basket level below the upper run of the individual belts in the first and in the second operating position.
  • An object can be moved into the reversing basket with the conveyor belt and extended in the same way in the second operating position. There is no direct friction of the objects on the turning basket.
  • a turning basket and an identical transport device can also be arranged in the drying cabin.
  • Nozzles for blowing the objects through the turning basket are preferably arranged under the conveyor belt in the drying cabin.
  • Figure 1 shows a relatively highly schematic device according to the invention, which essentially consists of a hermetically closable wet cabin 2 and a drying cabin 3, which adjoins the wet cabin.
  • a supply station 25 which is provided with a conveyor belt, is used to provide and supply contaminated pillows.
  • a housing 17 delimits the two cabins 2 and 3, the entire arrangement resting on a machine frame 42.
  • An entry door 18 which can be raised vertically.
  • An intermediate door 19 which can be raised in the same way separates the wet cabin 2 from the drying cabin 3, and finally an identical exit door 20 is provided at the exit of the drying cabin.
  • the decontaminated cushions are passed through the opened exit door 20 to a removal station 33, which leads, for example, to a transport container.
  • the doors 18, 19 and 20 can of course be controlled separately, so that sequential actuation is possible.
  • the equipment preparation system with fleet tanks, circulation pumps, boilers, controls, etc. is not shown.
  • a turning basket 6 is pivotally mounted about a pivot axis 14. Details of this swivel basket can be found in FIGS. 5 and 6.
  • the basket consists of two parallel basket levels 9 and 9 ', which are formed by parallel longitudinal profiles 10.
  • the basket is loaded through a receiving opening 8. Between the two Basket levels 9, 9 'are arranged on both sides of side profiles 32. These serve to guide the objects from the side.
  • the pivot axis 14 is mounted on both sides of the housing 17 in bearings 35, 35 '.
  • the drive takes place via a drive device, not shown here, for example via a stepper motor and a suitable gear.
  • the transmission contains, for example, a chain wheel 34, which is mounted on an output shaft 43 via a slip clutch 16.
  • the slip clutch protects the system from damage in the event of an accident on the reversing basket.
  • the output shaft is mounted in a bearing 36 in the machine frame and the connection to the swivel axis 14 takes place via a universal joint coupling 37.
  • the transport into the turning basket 6 or out of the turning basket 6 takes place via a conveyor belt 11 which has a plurality of parallel individual belts 44 (FIG. 5). These individual belts are offset from the longitudinal profiles 10 of the turning basket 6 and in the two operating positions I and II the basket levels 9 and 9 'lie below the level of the upper run 12 of the individual bands 44. Obviously, a pillow 1 can initially be so without touching the turning basket 6 are introduced in this. Washing and rinsing in the two operating positions I and II also takes place practically without touching the turning basket and only lying on the individual belts 44.
  • the turning basket 7 in the drying cabin 3 and the associated conveyor belt 13 are designed practically exactly the same as described above in connection with the wet cabin 2.
  • a treatment device for washing and rinsing is arranged transversely displaceably above the turning basket 6 in the wet cabin 2. Details of this can be seen in FIGS. 1 and 3.
  • the treatment device consists of a first spray bar arrangement 4 and a second spray beam arrangement 5.
  • the two spray beam arrangements are separately connected to a detergent source 38 or to a detergent source 39.
  • a flexible hose guide 24 ensures that an undisturbed supply of the liquids is possible in any position.
  • the spray bar arrangements 4, 5 are displaceable between the two rest positions R on both long sides of the device. In these rest positions, the spray bar arrangements lie outside the swivel range S of the turning basket 6.
  • a pulling device 23 is provided for the drive.
  • each spray bar arrangement has an individual section 40 and 41. These individual sections extend over the turning basket in the operating position I or in the operating position II. Control valves can be provided which direct the washing liquid or the rinsing liquid only into the individual section under which the turning basket 6 is located. At the bottom of the wet cabin II there is a collecting trough 21, via which the washing liquid or the rinsing liquid is discharged and fed to the equipment preparation system via a lifting pump. An exhaust air fan 22 is also connected to the wet cabin II, by means of which the vapors which form in the wet cabin 2 can be extracted. This is particularly important when the entrance door 18 is opened so that no disturbing immissions can occur.
  • collecting tubes 30 are arranged under the conveyor belt 13 at right angles to the direction of transport T. These manifolds are provided with individual air nozzles 15, which are directed upwards. The manifolds 30 are supplied with hot air via feed lines 29. This hot air is generated in a heat exchanger 27 which is fed with ambient air via a hot air fan 26. The heat exchanger is connected to an existing steam supply network via a steam connection 28, so that the ambient air can be heated. The exhaust air saturated with moisture from the drying cabin 3 is extracted and disposed of by an exhaust air fan 31.
  • the device according to the invention operates approximately as follows: A maximum of six pillows 1 are provided on the loading station 25. The first two are automatically inserted into the wet cabin 2 or into the reversing basket 6, for which purpose the entrance door 18 must be opened automatically. After closing the entrance door 18, the spray bar arrangement 4, 5 moves over the turning basket 6, which is still in the operating position I. A weak alkali of, for example, 60 ° C. is sprayed onto the pillows 1 from the detergent source 38. The special arrangement of the spray nozzles ensures optimal coating of the surface. As soon as the spray bar arrangement has reached a rest position R, the turning basket is turned into operating position II. The same process is now repeated, it being evident that the side of the pillow which previously formed the contact surface is painted.
  • the washing process can be repeated several times, the operating position always changing between the washing processes.
  • the rinsing process takes place, with fresh water being sprayed onto the pillows from the rinsing agent source 39 with relaxing agent, for example at 80 ° C.
  • both sides of the pillows are alternately treated by swiveling the reversing basket.
  • the turning basket is in the Operating position II, so that its receiving opening 8 faces the intermediate door 19. This is now opened and automatic actuation of the conveyor belts 11 and 13 leads to a transfer into the drying chamber 3 or into the turning basket 7.
  • the turning basket is pivoted several times while hot air is blown out of the nozzles 15 against the pillows.
  • the wet cabin 2 is of course already loaded with a new pair of pillows.
  • the dried pillows are removed from the drying cabin 3 and transferred to the removal station 33.
  • the hot air drying takes place at a temperature of approx. 90 ° C.
  • the system could also be used for objects other than pillows.
  • heat and / or cold storage materials welded into bags for medical purposes or plastic parts of all kinds can also be decontaminated.
  • the configuration of the turning baskets would have to be adapted to the respective circumstances.
