Definitions

  • the invention relates to a method, a device and a system for washing mattresses, in particular foam mattresses, according to the preambles of claims 1, 15 and 28, respectively.
  • a washing installation for mattresses is known from EP 0157252, in which the mattresses are passed one after the other through a plurality of tubs filled with liquids and are washed, disinfected, rinsed and dried. A special design effort for guiding and mechanical processing of the mattress is required.
  • the invention has for its object to provide a method for washing mattresses, which can be easily adapted to different requirements with regard to the treatments to be carried out, the amount and type of mattresses and enables the washing of a higher number of mattresses in the same time. Furthermore, a device is to be created which is suitable for carrying out the method and is structurally simple, and a system is to be made available which can be operated with the aid of the device according to the invention using the method according to the invention and with high performance and economy.
  • the mattress to be treated is treated in a walking device, the underside of which is only in the wash bath or just above it, while the liquid is applied to the top from above.
  • the device according to the invention makes it possible to assemble a system in a modular manner and to adapt it to the particular circumstances.
  • the device can be used for washing, disinfecting or rinsing. These processes can be carried out in succession in the same device in the bath changing process, so that a single device is sufficient for smaller systems.
  • several devices of the same type can be arranged one behind the other and / or in parallel and operated in continuous operation, a different time requirement for the different treatment processes being able to be compensated for.
  • the device shown schematically in Fig. 1 consists of a trough-shaped container 1, the internal dimensions of which are adapted to the largest mattress format to be treated.
  • a liquid 2 in the container which can be a washing, disinfecting or rinsing liquid.
  • a circulation conveyor in the form of a belt 3 is arranged in the container below the liquid level 2a and is guided around two deflection rollers 4, 5, at least one of which is driven.
  • the height of the conveyor unit formed by the belt and the deflecting rollers can be adjusted with respect to the liquid level 2a by means not shown.
  • Of the Liquid level is set via an overflow 32. The height of this overflow can be adjusted accordingly.
  • the mattress 6 to be treated On the belt 3 is the mattress 6 to be treated, which has the shape of a flat cuboid and can be provided with a cotton cover.
  • a flexing roller 7 is mounted, which extends over the entire width of the belt 3.
  • the fulling roller 7 can be moved in both directions over the length of the belt and is connected to a rotary drive which can be switched in both directions of rotation.
  • a drive for the linear reciprocation can also be present. Both their speed of rotation and the speed of the back and forth movement are adjustable.
  • the height of the flexing roller 7, which can be automatically adjusted to different mattress thicknesses, is adjusted in the manner shown that the mattress 6 is compressed or compressed below the roller.
  • the flexing roller 7 then rolls on the mattress 6 and continuously rolls it through.
  • the mattress is held immovably by the belt 3.
  • the flexing roller is moved into the right end position, while the mattress is inserted on the left side of the ball.
  • driving the fulling roller 7 it is prevented that the mattress 6 is shifted when starting the fulling roller.
  • the fulling roller rolls up on the mattress.
  • a liquid distribution system is located above the milling roller 7.
  • This can be designed in the form of a surge shower 8 with a slot-shaped outlet opening extends parallel to the rolling roller 7 located below.
  • the surge shower 8 is guided in a frame-like holder in such a way that it moves together with the flexing roller 7 and specifically supplies the liquid to the area just rolled.
  • Another preferred embodiment consists in the manner shown of a flat housing, the underside of which is provided with a large number of bores. Due to the liquid emerging from the holes, the mattress underneath is irrigated evenly over its entire surface.
  • a ball shower can also be provided, from which the liquid is sprayed over a larger area.
  • a further possibility of supplying and distributing the liquid consists in guiding the liquid into the interior of the rolling roller 7, which then has to be designed as a perforated roller, so that the liquid is fed directly to the rolled area.
  • the liquid is removed from the container 1 and fed with a pump 9 through a line 10 to the liquid distribution system, from where it returns to the container 1 in the circuit.
  • two press or squeeze rollers 11, 12 are arranged, which form a gap between them for the passage of the mattress, the mattress being largely dewatered by this liquid soaked up.
  • the gap is located above the liquid level 2a and its width can be adjusted.
  • the press rolls are coupled with a suitable drive, which can act on one or both rolls.
  • a plurality of storage containers 13, 14, 15 are arranged below the container 1, from which everyone can hold the entire contents of the trough-shaped container 1.
  • a line 16 and a valve 17 the liquid is supplied from the container 1 into one of the storage containers 13, 14 or 15, and a line 18 and a pump 19 are used to fill the container 1 from one of the storage containers Container 1, like the storage containers 13, 14, 15, is connected to a channel drain 33.
  • the mattress 6 to be treated is inserted into the device from the left side in FIG. 1 and placed on the belt 3 with the front edge.
  • the belt then transports the mattress 6 in the direction of the arrow 34 into the position shown in the drawing.
  • the fulling roller 7 is in its right end position.
  • the upper run of the belt 3 is set at such a height that the inserted mattress is not completely immersed in the liquid, but only with its underside.
  • the immersion depth depends on the thickness and density of the mattress and is dimensioned so that the mattress does not float in the liquid, but remains on the belt due to its own weight.
  • the fulling roller 7 is rotated to the left by the drive in the manner shown in dashed lines and moved to the left.
  • the own rotary drive of the flexing roller causes the roller to roll on the mattress, compressing it underneath and not shifting it to the left.
  • the mattress is held by the belt.
  • the pump 9 is switched on, so that liquid from the container 1 passes through the line 10 is pumped to the surge shower 8, which is located in the manner described above the fulling roller.
  • the flexing roller 7 presses the mattress 6 together in the manner shown and squeezes the absorbed liquid out of the compressed area.
  • liquid is again sucked up from the container 1.
  • liquid is supplied from above from the surge shower 8. In this way, the mattress is tumbled and, at the same time, alternately squeezed and relieved with an abundant supply of fluid, so that there is a thorough flooding.
  • the mattress After pressing, the mattress is fed to the next treatment step.
  • the device according to the invention can be used in different ways in the context of an overall system for treating mattresses.
  • a single device of this type is sufficient, which is then operated using the bath changing process.
  • the mattress 6 is introduced in the manner described the container 1 filled with a washing liquid and the mattress washed. After completion of this process, the washing liquid is drained through the line 16 and the valve 17 into the reservoir 13.
  • the flexing roller 7 can be guided over the mattress one or more times with the pump 9 switched off and the washing liquid drained off in order to squeeze out as much of the liquid as possible.
  • the belt 3 can also be raised or the flexing roller can also be lowered in order to achieve better drainage.
  • the pump 19 is switched on in order to pump disinfectant liquid from the storage container 14 into the container 1 through the line 18.
  • the treatment is then carried out in the same way,
  • FIG. 2 An example of such a system is shown schematically in FIG. 2.
  • three individual devices of the type shown in FIG. 1 are arranged in series, through which the mattresses pass one behind the other.
  • the mattresses are inserted into the first device 20 and subjected to a first washing treatment and then transferred successively to the devices 21 and 22, in which they are then disinfected and rinsed. From the device 22, the transport takes place in a further device for drying.
  • the washing is not carried out in the bath changing process, but in the countercurrent process, i.e. the washing liquid is conveyed from one device to the next by pumps 23 and 24 and lines 26 and 27 against the direction of transport of the mattresses and leaves the first device through an overflow 29.
  • the pumps 25 supply the shower with line 28 via liquid. If the devices 20, 21, 22 are installed at different heights, the liquid can be conveyed through a natural gradient and the pumps 23 and 24 can be dispensed with.
  • the individual devices can also be operated in a different way than explained in connection with the bath changing process.
  • the belt 3 and the dewatering rollers are not stopped, but continue to be operated, during the flexing of the mattress 6 by the flexing roller 7, so that the mattress moves slowly through the device and is treated continuously.
  • the transport speed of the belt and the dewatering rollers must be noticeably lower than the linear speed of the flexing roller. With this mode of operation, a completely continuous operation of the system is possible.
  • FIG. 3 A further possibility of arranging several devices in an overall system is shown in plan in FIG. 3. This system takes into account the fact that disinfection generally takes more time than washing.
  • the system outlined in Fig. 3 as an example consists of a device marked with "W” for washing the Mattresses, two “D” devices for disinfection, one with “S” devices for rinsing and two devices with "T” devices for drying.
  • the individual devices W, D, D, S can also be arranged one behind the other, as shown in the right part of FIG.
  • the two disinfecting devices work in parallel and are loaded alternately by the washing device W, so that the increased time requirement is compensated. Or they work one after the other, with the mattress in each disinfection device D only staying half of the disinfection time.
  • the mattresses are directed from the rinsing device S to the dryers arranged here in parallel.
  • the individual devices are not spatially arranged in a row, but partly separated from each other. Depending on the local conditions, they can also be located in different rooms.
  • the mattresses are transported from one device to the next by suitable conveyors 30, 31 which e.g. can be designed as a lifting belt.
