Definitions

  • the invention relates to a method for dosing a paste-like, thixotropic detergent into an especially commercial washing machine by means of a dosing device.
  • Paste-like, essentially water-free detergents are mainly used in commercial laundries. Examples of such pastes are described in DE 38 26 110 AI and in DE 37 19 906 AI.
  • the advantages lie in the high washing power as a result of the high concentration of washing-active components compared to powder-form washing agents, since washing-inactive additives which only serve to condition the washing agent are not necessary here.
  • a barrel is provided as a storage container for the pasty detergent in this prior art.
  • a plate that is movable in the barrel and closes close to the barrel walls which is also called a follow-up plate, lies on the paste and enables conveyance via a simple pipeline with a suction pump (DE 37 19906 AI and DE 38 26 110 AI).
  • the removal process is suitable for pastes with a viscosity at around 75,000 to 90,000 mPa s.
  • a stirrer below the follower plate is proposed in G 93 14 591, which liquefies the paste located immediately below the follower plate and thus makes it easy to convey.
  • the follower plate according to the prior art does not exert any pressure on the paste.
  • the paste is only conveyed using a particularly powerful suction pump.
  • the use of such an expensive pump is only economical with relatively large containers.
  • a device for the almost complete emptying of flexible disposable containers filled with fluids is known from DE 42 18 297 A1.
  • the relatively flat bag which is wedge-shaped in cross section, has an outlet opening on its upper side. To empty it, it is placed between two plates and the outlet opening is connected to a pipe. The plates are moved against each other by means of a pressure cylinder and the fluid contained in the container is pressed out.
  • this removal method is not suitable for bags filled with thixotropic paste, since the pressure acting on the entire top of the container is generally not sufficient to completely and sufficiently liquefy the paste.
  • the known method for emptying the flat bags is also not suitable for exact dosing, since the movement of the plates is in a non-linear and complicated connection with the volume pressed out.
  • the present invention has in particular set itself the goal of enabling the use of pasty detergents in the OPL area ("on premise laundry") in an economical manner.
  • Containers of 5 to 10 1 corresponding to 7.5 to 15 kg of detergent are typically used here.
  • the known metering methods for pasty detergents have so far only been designed for larger containers, are correspondingly expensive and are not suitable for use in the OPL area. Powder detergents with the disadvantages described above are therefore used in the OPL area.
  • block detergents in this area of application. To introduce this detergent into the washing machine, water is sprayed onto this block at a temperature of about 50 to 60 ° C. and part of the detergent is dissolved. The temperature mentioned is required in order to release a sufficient amount of detergent from the detergent block in a reasonable time. Disadvantage g in this process is the need to keep hot water ready. If the washing liquor is heated up in the washing machine, this leads to the need for an additional device for hot water preparation.
  • the invention also aims to achieve the following objectives. Refilling the paste into a dosing container should not be necessary. The paste should be taken directly from the sales container or a part of the sales container, exactly dosed and at the same time washed into the washing machine. Direct contact of the operating personnel with the product, which is highly caustic due to the content of metasilicate, should be avoided as far as possible.
  • the method should in particular be tailored to the needs of smaller commercial laundries and laundries in smaller hotels and homes (OPL).
  • OPL hotels and homes
  • the invention seeks to create a particularly cost-effective way of using paste-like detergents.
  • This object is achieved according to the invention in the method mentioned at the outset by placing the sales container or a portion thereof filled with the detergent in a receptacle of a dosing device and opening on the underside in a first method step, and the detergent volume-controlled from above in the second method step Pressurized and in the third process step, the paste emerging on the underside is washed into the washing machine with water.
  • volume-controlled is to be understood here as a control depending on the target volume of the paste emerging from the container.
  • the paste is not sucked off according to the invention, but is pressed out of the container from above.
  • this emptying method is sufficient to allow a sufficient amount of paste to be metered precisely and to leave the container quickly enough.
  • a plastic bag filled with the detergent in particular a stand-up pouch, is removed from a cardboard drum belonging to the packaging and placed in the receptacle of the metering device.
  • the container can be changed very quickly, the adjustment container is very easy to clean if it is dirty, and a product change is simplified.
  • the plastic bag is first placed in a standing cylinder and then placed in the receptacle of the metering device.
  • the stand cylinder is removed from the receptacle together with the still partially filled plastic bag, and a new stand cylinder with a different product is inserted into the receptacle.
  • the sales container consisting of a cartridge with a cartridge base that can be moved in the cartridge cylinder, is inserted with the opening facing downward into the receptacle of the metering device.
  • the part of the sales container surrounding the detergent in particular the plastic bag or the cartridge, consists of a material which is resistant under the conditions of customary commercial washing processes. After emptying, the temperature, chemical and water-resistant material can be washed in the washing machine, if necessary after being cut. In this way, product residues are removed from the packaging material and used according to their purpose. The cleaned packaging material can be recycled or simply disposed of.
  • the necessary relatively low excess pressure can be applied to the paste in process step 2, in which pressure is applied to a plate resting on the paste.
  • the plate can already be contained in the sales container, namely in the plastic bag. It is also possible, however, to first open the sack and place the plate on the paste.
  • a simple solution to the environmental problems of the packaging is achieved if the plate also consists of a material which is resistant under the conditions of normal commercial washing processes. With the relatively small containers used in the OPL area, it is possible to wash this plate, whose diameter can be, for example, about 20 cm, in the washing machine and dispose of it in the same way as the plastic bag, which is resistant to the washing processes.
  • polyethylene can serve as such material.
  • the volume-controlled application of pressure to the detergent from above can be done in different ways.
  • the cartridge base or the plate is moved downward by a controllable drive and in particular a threaded spindle by a defined stroke corresponding to the desired paste volume to be metered in.
  • a lifting cylinder can also be used as the drive.
  • the volume taken up by the detergent in the receptacle can be reduced in a defined manner by metering the same volume of a liquid, in particular water, into the space between the plastic bag.
  • the plate already mentioned can rest on the paste.
  • the cartridge base can also be moved downwards in a corresponding manner.
  • the paste has a very high viscosity and a high proportion of non-ionic surfactants
  • a water jet is directed onto the paste strand emerging from the receptacle and is thus divided into individual pieces.
  • a gel forms on the surface of the paste strand, which prevents the entry of further water and the dissolution of the paste strand.
  • the paste is broken down into small, rapidly distributing and dissolving particles by the action of shear forces before the nonionic surfactants swell to form the viscous, gel-like mass.
  • the paste emerging at the bottom of the receptacle is mixed with water immediately after the outlet and only then washed into the washing machine together with the water, optionally by means of a feed pump.
  • a feed pump is not required if only a single washing machine is to be supplied.
  • the paste mixed with water can then flow from a metering device mounted above the washing machine due to gravity via a vertical line into the dispenser or directly into the washing machine. If several washing machines are supplied with the paste via a single metering device, the paste mixed with water can be fed to the respective machine via a feed pump.
  • the feed pump below the mixing container can be used as a simple, inexpensive pump, e.g. B. as a small centrifugal pump.
  • the invention also relates to a device for dosing thixotropic, highly viscous detergent pastes, which are preferably used in commercial laundries, with a mixing container with a water connection and a line from the mixing container to one or more washing machines.
  • the device has a receptacle for the sales container or the part of the sales container filled with the detergent, an opening in the lower region of the receptacle and means for generating a pressure and a defined volume reduction in the upper region of the receptacle.
  • the mixing container is located below the opening.
  • Opening the sales container is made easier if the opening in the lower region of the receptacle is designed as an upwardly projecting mandrel. To open the sales container, it is sufficient to insert the container into the receptacle.
  • the complete emptying of the sales container designed as a sack is facilitated by a fastening device for releasably clamping the edge of the sack at the upper edge of the receptacle.
  • the fastening device can be designed as a clamping ring or snap lock for a lid of the receptacle or the like.
  • the pressure provided according to the invention for pressing out the paste can be exerted on the paste in different ways.
  • a lockable cover of the upwardly open receptacle and a pressure pad attached below the cover and movable by a controllable drive away from the cover by defined strokes are provided for this purpose.

Pumps of this type are manufactured in motor vehicle technology as delivery pumps for windshield washer water in large numbers and inexpensively. If a certain volume of paste is to be metered in, the pump presses the same volume of liquid, for example water, into the upper region of the receptacle. An exact, simple and inexpensive dosage is possible in this way.
