Definitions

  • the invention relates to a device for cleaning a sponge disc having a sponge with a container for cleaning liquid and with means arranged outside the cleaning liquid for supporting the sponge when squeezing out.
  • Such devices are used in particular for cleaning sponge disks, which are provided for washing freshly grouted tiles on a wall or floor.
  • the sponge disc usually has a handle mounted on a board and the sponge on the side of the board facing away from the handle.
  • a device known from practice has two rollers attached to the container with cleaning liquid as a means for supporting the sponge when it is squeezed out. For cleaning, immerse the sponge disc in the cleaning liquid and then roll it over the rollers. Here, a pressing force required to squeeze out the sponge is applied by hand. This process is repeated several times until the sponge is thoroughly cleaned.
  • cleaning the sponge with the known device is very time-consuming and often takes just as much time as washing the tiles. To avoid a remaining gray haze on the tiles, wash the tiles and clean the sponge as quickly as possible.
  • a cleaning of the sponge disc while washing the tiles with a second sponge disc is with the known device not possible without additional help.
  • the invention is based on the problem of designing a device of the type mentioned at the outset in such a way that it cleans the sponge disk particularly reliably without requiring the attention of a person washing the tiles.
  • This problem is solved according to the invention in that it has pressing means for generating a required pressing force when squeezing the sponge and a conveying device for moving the sponge disk from the cleaning liquid to the means for supporting the sponge and into a removal position located outside the cleaning liquid.
  • the sponge disc is simply placed in the container with the cleaning liquid.
  • the sponge in the sponge disc absorbs cleaning fluid.
  • the conveyor moves the sponge disc to the means for supporting the sponge, where the force required for squeezing is applied, and finally to the removal position.
  • This process can be repeated any number of times until the sponge disc is thoroughly cleaned. Since this cleaning process requires little or no attention, the tiles can be washed off with a second sponge during this time.
  • the soiled sponge disc is then placed in the cleaning liquid and the clean sponge disc is removed from the removal position. Thanks to the invention, a particularly large area of grouted tiles can be washed off by a person in a very short time. Since the device applies the pressing force required to squeeze out the sponge, the cleaning of the sponge disk takes place particularly fatigue-free.
  • the device according to the invention is suitable for cleaning an almost arbitrarily designed sponge disc, which has, for example, a particularly absorbent sponge or one with a relatively thin fleece.
  • the sponge disc can also have a handle on its top, a long handle for cleaning the tiles while standing, or the like.
  • the conveyor could be driven, for example, with a hand crank or a lever.
  • a hand crank or a lever you have to briefly interrupt the washing of the tiles. An interruption of the washing can be avoided according to an advantageous development of the invention if the device has an electric motor for driving the conveyor.
  • the conveyor could, for example, have a plurality of rollers arranged in a row and driven by the electric motor.
  • the sponge is reliably gripped by the conveying device and moved to the means for supporting the sponge.
  • the conveyor device consists of a few components and is structurally particularly simple if the conveyor device has at least one conveyor belt.
  • the means for supporting the sponge and the pressing means are structurally particularly simple if, as means for supporting the sponge, they have at least one squeezing roller or a conveyor belt and as pressing means a pressure roller arranged at a short distance above the squeezing roller or the conveyor belt having.
  • the sponge disc is removed from the conveyor moved to the squeezing roller and thereby pressed by the pressure roller against the squeezing roller or the conveyor belt.
  • the cleaning liquid squeezed out of the sponge runs down the squeezing roller or past the conveyor belt.
  • sponge disks of different thicknesses can be cleaned if the distance between the pressure roller and the conveyor belt or the pressure roller is adjustable.
  • the sponge disc is cleaned particularly thoroughly if it has a spray system for spraying the sponge with cleaning liquid.
  • used cleaning liquid is separated from clean cleaning liquid if the device has a guide of the cleaning liquid squeezed out of the sponge into a second container separated from the container with cleaning liquid. This directs dirty cleaning fluid squeezed out of the sponge into the second container. As a result, the cleaning liquid remains largely clean and is refilled if necessary.
  • the device has a control device that switches the electric motor for moving the sponge disc several times into the cleaning liquid and for the means for supporting the sponge. Tests have shown that repeating the cleaning process two or three times is sufficient to reliably clean the sponge disc.
  • the device can be produced inexpensively if the conveyor belt is made of plastic.
  • the conveyor belt is characterized by high stability if it has a chain made of metal links.
  • the sponge disc inserted in the cleaning liquid is captured particularly reliably by the conveyor belt if the conveyor belt has knobs pointing upwards for taking the sponge disc with it.
  • a plurality of knobs can be provided which hook into the sponge and carry the sponge disc with it.
  • a few particularly long nubs can also be provided which engage behind the sponge disc. The distance between the knobs should be larger than the sponge disc is long.
  • the sponge disc is securely positioned with respect to the pressure rollers if a guide rail for guiding the sponge disc is arranged on the side next to the conveyor belt and / or the pressure roller.
  • the control of the electric motor is particularly simple if it has sensor elements designed to switch the electric motor as a function of the position of the sponge disc.
  • Sensor switches that can be actuated by the sponge disk can be used as sensor elements, for example.
  • the sensor elements are insensitive to contamination if the sensor elements are used to detect the position of a magnet arranged in the sponge disc are trained.
  • reed contacts are suitable as sensor elements.
  • the device 1 shows a device arranged in a container 1 filled with cleaning liquid for cleaning a sponge disc 3 having a sponge 2.
  • the device has a conveyor device 4 with a plurality of conveyor belts 5, 5a and an ejection roller 6. Above the conveyor belts 5, 5a and the ejection roller 6, three pressure rollers 7 - 9 arranged in a row are arranged.
  • FIG. 2 shows that three pressure rollers 7-12 are arranged on each side of the device.
  • the pressure rollers are arranged on a rocker 13 in their height and their inclination adjustable.
  • the conveyor belts 5 have a plurality of knobs 14 on their upper side and are driven by rollers 16, 17 mounted in a frame 15 of the device.
  • One of the rollers 17 of the conveyor belts 5, 5a is driven by an electric motor 18 via a V-belt 19.
  • the frame 15 has in its end regions each have a limit switch 20, 21, the signals of which are fed to a control device 22 of the electric motor 18.
  • the sponge disc 3 is guided laterally by a guide rail.
  • the sponge 2 absorbs cleaning liquid. Then the sponge disc 3 actuates the lower limit switch 21, whereby the electric motor 18 is switched on. The switching of the electric motor 18 can either take place after a predetermined delay time or immediately.
  • the sponge disc 3 is then moved out of the cleaning liquid by the conveyor belts 5, 5a to the squeezing roller 6.
  • the pressure rollers 7-12 press the sponge disc 3 against the pressure roller 6 and thus the cleaning liquid out of the sponge 2.
  • the pressure rollers 7-12 are inclined slightly in the direction of the pressure roller 6. This ensures simple threading of the sponge disc 3 and continuous squeezing of the sponge 2.
  • the electric motor 18 continues to move the sponge disc 3 until it reaches the upper limit switch 20.
  • the electric motor 18 is then switched over and moves the sponge disk 3 back into the cleaning liquid. This process is repeated two to three times.
  • the upper limit switch 20 then switches off the electric motor 18.
  • the sponge disc 3 remains in the position in contact with the upper limit switch 20. This position characterizes the removal position in which the cleaned sponge disc 3 can easily be removed by the device. If a second sponge disc is placed in the cleaning liquid, its sponge soaks up the cleaning liquid and reaches the conveyor belt 5. After the sponge disc in the removal position has been removed, the electric motor 18 is started and the second sponge disc is cleaned.
  • FIG. 3 shows a device according to the invention with a spray system 24 for spraying the sponge disk 3 with cleaning liquid.
  • the spray system 24 has a feed pump 25 arranged in the container 1 and a spray nozzle 26 arranged below the conveyor belt 5.
  • the conveyor belt 5 consists of chains 27 with metal links 28 and is driven together with the ejection roller 6 by the electric motor 18 via a chain 29 without slippage.
  • a sensor element 30, 31 are arranged, which are designed to detect the position of the sponge disc 3.
  • a magnet 32 is arranged in the sponge disc 3.
  • the sensor elements 30, 31 generate an electronic signal with which the feed pump 25 and the electric motor 18 of the conveyor belt 5 and the squeezing roller 6 are switched. As a result, the position of the sponge disc 3 is detected regardless of contamination.
  • a further container 33 is arranged below the squeezing roller 6 and holds cleaning liquid squeezed out of the sponge 2 of the sponge disk 3.
