Definitions

  • the invention relates to a device for cleaning containers of the type explained in the preamble of claim 1.
  • the invention finds particular application in the cleaning of bottles or other beverage containers prior to their filling with beverages.
  • the containers should be visually clean and shiny, on the other hand, the containers should be brought to a hygienically perfect condition before filling in order to avoid contamination of the beverage with microorganisms as far as possible.
  • the label or the like marking agent and the adhesives for their attachment must also be removed without residue.
  • This demanding cleaning process is carried out in a variety of cleaning stations, which must pass through the container in succession.
  • cleaning stations include, for example, Lauge awarenessen different design, and then rinsing treatments in which only water is used as a cleaning liquid.
  • the known construction has hitherto been used for rinsing the containers after they have undergone various lye treatments.
  • the principle of water recycling was both between a subsequent cold water catch basin and a previous hot water catch basin and between a subsequent hot water tank and a second previous Hot water tank used.
  • a disadvantage of this embodiment is the relatively low degree of dilution that the recycled water exerts on the more heavily polluted water supply in the collecting container of the previous cleaning station, since the recirculated water is always mixed with the entire volume of water of the previous cleaning station.
  • the invention has for its object to provide a device for cleaning containers, which offers a more effective use of the cleaning fluid used.
  • the object is achieved by the device described in claim 1 and by the method described in claim 8.
  • This particularly relates to cleaning stations, which have a collecting container for used cleaning liquid from which the cleaning liquid for spraying the container is removed continuously and in which the cleaning liquid is collected again after the spraying.
  • These collecting containers have a relatively large receiving volume, so that the proportion of the diluting, clean cleaning liquid from the subsequent cleaning process with respect to the volume fraction of the cleaning liquid circulated in the previous cleaning process is increased particularly strongly during the inventive return to the supply line.
  • the return line preferably opens via an overflow, which unfolds a collecting effect.
  • the return line leading to the pump ensures uniform mixing.
  • a filter ensures that coarse dirt can be filtered out of the collecting container.
  • the supply of fresh water to replace the carried by the container from the cleaning equipment detergent or other losses is preferably carried out again on the return of already used cleaning liquid from the last rinse.
  • the invention is applicable in any cleaning system in which a plurality of cleaning stations are provided, which use the same type of cleaning liquid.
  • the Fig. 1 shows section of a device 1 for cleaning containers 2.
  • the container 2 can be of various types, but are preferably beverage containers and in particular beverage bottles.
  • the device 1 can be designed as a single-end or double-end cleaning machine and is connected in the illustrated embodiment of a filling machine for filling the container 2 with beverage, but can be used wherever containers must be cleaned very clean and / or hygienic.
  • the containers 2 are arranged on one of the conventional conveying devices 3, the conveying device 3 transporting the containers 2 through the device 1 in the conveying direction F, preferably continuously.

It can be rinsed in the second cleaning station 4.2 with hot water at a first temperature in the third cleaning station 4.3 with hot water at a second, lower temperature in the fourth cleaning station 4.3 with cold water and in the fifth cleaning station 4.5 with fresh water.
  • the invention is not only used for rinsing containers 2 with water but everywhere where multiple rinses are to be performed with a cleaning liquid of the same kind.
  • the first four cleaning stations 4.1 to 4.4 each contain a collecting container 5.1 to 5.4, which are arranged below the conveyor 3. Each cleaning station further contains an injection device 6.1, 7.2, 7.3, 7.4 and 7.5 supplied with cleaning agent by a supply line 6.1, 6.2, 6.3, 6.4 and 6.5 for tapping the containers 2.
  • the injection device 7.1 to 7.5 may have any suitable configuration and contains in the illustrated embodiment in the cleaning stations 4.1 to 4.4 each an upper nozzle or nozzle group 8, the cleaning liquid from above or in the container 2, and a lower nozzle or nozzle group 9, the Cleaning liquid from below or into the container 2 injected, as z. B. in the EP 1 144 016 is described.
  • Each of the supply lines 6.1 to 6.4 contains a pump 10.1 to 10.4 and a pump upstream filter 11.1 to 11.4. Pump 10 and filter 11 are conventional.
  • the final cleaning station 4.5 in the conveying direction F serves for rinsing with fresh cleaning agent, in particular fresh water, and contains only the lower nozzle or nozzle group 9, but can be provided with upper and lower nozzles analogously to the other injection devices.
  • the last cleaning station 4.5 does not contain a catch tank but a gutter or catch plate 13 which is inclined to collect the collected cleaning liquid.
  • the last in the conveying direction F cleaning station 4.5 in turn has a supply line 6.5, which is connected to a fresh water source and to an injection device 7.5 leads, which contains only the lower nozzle or the lower nozzle group 9 in the illustrated embodiment.
  • cleaning liquid is gradually returned from downstream cleaning stations to upstream cleaning stations, in which use of the fresh cleaning agent is expedient and necessary in order, for.
  • a return device 12 cleaning liquid is gradually returned from downstream cleaning stations to upstream cleaning stations, in which use of the fresh cleaning agent is expedient and necessary in order, for.
  • the fresh cleaning agent is expedient and necessary in order, for.
  • these are the fourth, with cold water, and the third and the second cleaning station, both of which work with hot water.
  • the return device 12 contains in each case a return line 12.1, 12.2 and 12.3, wherein the return line 12.1 is a flow connection between the fifth and the fourth cleaning station 4.5 and 4.4, the return line 12.2 a connection between the fourth cleaning station and the third cleaning station 4.3 and the return line 12.3 a flow connection between the third cleaning station 4.3 and the second cleaning station 4.2 creates.
  • the return line 12.1 is arranged with its orifice 14.1 at or in the vicinity of the lowest point of the channel 13, while the orifices 14.2, 14.3 of the return lines 12.2, and 12.3 arranged in the associated collecting container 5.4 and 5.3 and are designed as an overflow, the same time Level of the respective collection container 5.3 or 5.4 determined.

  • Return lines of the type described can also be provided between the second collecting container 5.2 or the first collecting container 4.1 and further upstream collecting containers, provided that they work with the same cleaning agent or if mixing of the cleaning agents of the different cleaning stations does not bother. Furthermore, only selected cleaning stations from a group of working with detergent of the same kind stations can be connected to a return line
  • connected to the overflow 14.3 line 15 leads either in a disposal facility or for further use of the withdrawn detergent, for example, to exploit the heat content of the cleaning liquid from the second cleaning station 4.3 or the like.
  • the collecting container 5.1 of the first cleaning station 4.1 is provided with an overflow 14.5, which is connected to a line 16 through which the liquor located in the collecting container 5.4 (in the illustrated embodiment) either deducted for disposal or, analogously to the above Return device in the rinsing area, is used again in a previous cleaning step.
  • the containers 2 are passed through the device 1, so that they first enter the first cleaning station 4.1 and are treated there with cleaning liquid from the collecting container 5.1. Then, the containers gradually pass through the second, third and fourth cleaning stations 4.2 to 4.4, in which they are each treated with the cleaning agent from the associated collecting container 5.2 to 5.4, respectively via the associated supply line 6.2 to 6.4 of the associated sprayer 7.2 to 7.4 (effected by the pumps 10.2 to 10.4) is supplied. Subsequently, the containers 2 reach the cleaning station 4.5 in the illustrated embodiment, in which they are rinsed clean with a surge of freshly supplied detergent, in the illustrated embodiment with a fresh water surge on the supply line 6.5 and the nozzle 9.
  • the here again dripping from the containers 2 detergent passes through the channel 13, the mouth 14.1 and the return line 12.1 in the supply line 6.4 of the previous cleaning station 4.4 and thinned there by the pump 10.4 extracted from the collecting container 5.4 detergent.
  • the cleaning agent passes over the container 2 and drips again into the collecting container 5.4. If the level in the collecting vessel 5.4 of the fourth cleaning station 4.4 rises to overflow 14.2, then the cleaning agent is returned from the collecting vessel 5.4 via the return line 12.2 into the supply line 6.3 of the previous cleaning station 4.3 and arrives there in the detergent stream passing through the pump 10.3 the collecting container 5.3 of the third cleaning station 14.3 is sucked off.
  • the diluted detergent in this way then passes into the sprayer 7.3 and is passed over the container 2. Subsequently, the cleaning liquid drips back into the collecting container 5.3.

Then the cleaning liquid drips back into the collecting container 5.2. If the level in the second collecting container 4.2 is exceeded, cleaning agent can be removed via the overflow 14.4 and the line 15.
  • the volume of the supply line 6 is substantially smaller than the volume of the associated collection container 5, a much more effective mixing or dilution with a higher ratio factor can take place through the here recirculating return line, as would be the case, for example, if an overflow between the collection containers with each other would exist. Since normally the cleaning agent from the subsequent cleaning stage is not so heavily polluted or so heavily loaded with the cleaning liquor as the cleaning agent from the previous cleaning station, the recirculation via the recirculation line will result in an improvement, i. Dilution that reaches the cleaning fluid of the previous cleaning stage.
  • a direct overflow 17 between suitable cleaning stations 4 are provided, but preferably only become effective when the return line is overwhelmed and there is a risk of leakage.
  • a safety overflow 17.1, 17.2, 17.3 can z. B. between the channel 13 and the fourth collecting container 5.4 and between the collecting containers 5.4 and 5.3, and 5.3 and 5.2 are provided.
  • the invention can also be used in other cleaning devices in which cleaning liquid should be optimally utilized.
