Definitions

  • the present invention relates to a container cleaning machine according to independent claim 1 and a cleaning method for containers with a container cleaning machine according to independent claim 8.
  • Container cleaning machines are basically known from the prior art. These include a suitable transport device for the containers to be cleaned, such as bottles.
  • the transport device can include one or more receptacles, also called container cells, into which the containers can be placed and transported by the container cleaning machine.
  • Known container cleaning machines usually include at least one cleaning bath in which a cleaning fluid is kept, into which the containers are completely or partially immersed in order to be cleaned.
  • the technical problem to be solved is to provide a container cleaning machine and a cleaning method for containers with which the removal of even more aggressive dirt or labels can be achieved with the lowest possible energy expenditure and/or construction effort.
  • the container cleaning machine for cleaning containers, such as bottles, comprises a cleaning bath and a transport device for transporting containers through the cleaning bath, the cleaning bath having at least one injector nozzle for causing a flow of a cleaning fluid in the cleaning bath along an outflow direction from the injector nozzle in the direction of a container transported through the cleaning bath.
  • the injector nozzle can preferably work according to the Venturi principle and can therefore release more cleaning fluid from an outflow opening of the injector nozzle in the outflow direction than was supplied to the injector nozzle via a pump, for example.
  • the injector nozzle can be connected via a screw cap or other fastening means to an outflow opening of a fluid circuit for the cleaning medium present in container cleaning machines.
  • the container cleaning machine further comprises a suction for suctioning cleaning fluid from the cleaning bath and wherein the injector nozzle is arranged such that the outflow direction of the flow from the injector nozzle is in the direction of an outflow opening of the injector nozzle Suction is running.
  • the suction can also be used to remove contaminants, such as detached labels or dirt from the container.
  • the transport device runs between the injector nozzle and the suction, so that the flow hits a container transported by the transport device.
  • the outflow direction forms an angle with a transport plane of a container in the transport device in a region in which the flow hits the container transported through the cleaning bath.
  • the angle is particularly preferably between 5° and 85°, or between 20° and 75°, or between 35° and 65°.
  • the transport device comprises a plurality of receptacles for receiving a container, the receptacles comprising an inflow opening and an outflow opening and the flow in the direction of the inflow opening in an area in which the flow hits the container transported through the cleaning bath Recording progresses.
  • This embodiment ensures that cleaning medium can flow completely around the containers even in the receptacles, which improves the cleaning result.
  • the injector nozzle can be arranged pivotably mounted on an oscillating shaft.
  • the shaft can be designed as a hollow shaft and alternatively or additionally have transverse bores, whereby cleaning fluid can be supplied to the feed area of the injector nozzle. Due to the oscillating movement of the shaft, the outflow opening can accompany the container to be cleaned in the transport direction for a short period of time. In this way, the impact angle between the direction of flow of the cleaning fluid and the container to be cleaned can be changed and the treatment time can be increased. This improves the cleaning result.
  • the cleaning method according to the invention for containers, such as bottles, with a container cleaning machine comprising a cleaning bath and a transport device for transporting the containers through the cleaning bath, the cleaning bath having at least one injector nozzle for causing a flow of a cleaning fluid in the cleaning bath along an outflow direction from the injector Nozzle in the direction of a container transported through the cleaning bath, includes applying cleaning medium to the containers through the injector nozzle at least partially during the transport of the containers through the cleaning bath.
  • This process can improve the cleaning results of containers.
  • the container cleaning machine further comprises a suction which sucks cleaning fluid out of the cleaning bath, and wherein the injector nozzle is arranged such that the outflow direction of the flow from the injector nozzle runs in the direction of an outflow opening of the injector nozzle for suction.
  • Contaminants can thus be reliably removed from the container and simultaneously drawn off from the cleaning fluid in the cleaning bath.
  • the transport device runs between the injector nozzle and the suction and the flow hits a container transported by the transport device.
  • the outflow direction forms an angle with a transport plane of a container in the transport device in an area in which the flow hits the container transported through the cleaning bath.
  • a force component can also be caused by the flow of the cleaning fluid tangentially to the surface of the container, so that the cleaning result is improved.
  • the angle is between 5° and 85°, or between 20° and 75°, or between 35° and 65°
  • the transport device comprises a plurality of receptacles for holding a container, the receptacles comprising an inflow opening and an outflow opening and the flow in an area in which the flow hits the container transported through the cleaning bath in the direction the inflow opening of the receptacle runs.
  • This design of the injector nozzle allows a large amount of cleaning fluid to be transferred to the container.
  • the injector nozzle can be arranged pivotably mounted on an oscillating shaft.
  • the shaft can be designed as a hollow shaft and alternatively or additionally have transverse bores, whereby cleaning fluid can be supplied to the feed area of the injector nozzle. Due to the oscillating movement of the shaft, the outflow opening can accompany the container to be cleaned in the transport direction for a short period of time. In this way, the impact angle between the direction of flow of the cleaning fluid and the container to be cleaned can be changed and the treatment time can be increased. This improves the cleaning result.
  • cleaning fluid is supplied to the injector nozzle via the feed area and exits from the outflow opening via the intake area and the outlet area, the amount of cleaning fluid emerging from the outflow opening being at least 2 times, or at least 3 times, or at least 4 times, or at least 5 times the amount of cleaning fluid supplied via the feed area.
  • the forces acting on the container to remove dirt and/or labels can be particularly advantageously increased without increasing the amount of cleaning fluid actively supplied to the nozzle, for example by a pump, so that the energy required to be applied can be kept as low as possible.
  • Fig. 1 shows a container cleaning machine 100 according to one embodiment.
  • the container cleaning machine is basically designed as already known from the prior art.
  • the container cleaning machine 100 can thus be arranged between a feed device 150 for containers, such as bottles, 130 and a discharge device 160 for cleaned containers 130.
  • Feeding device 150 and removal device 160 can, for example, be designed as mass transporters in which the uncleaned containers 130 or the cleaned containers are transported in a disordered manner.
  • a transport device 102 also extends within the container cleaning machine 100, by means of which the containers 130 can be transported, preferably individually and in an orderly manner, from the feed device 150 to the discharge device 160.
  • the containers can be cleaned during their transport along the transport device 102.
  • the container cleaning machine 100 includes a cleaning bath 101, which can be filled with a cleaning fluid 140, for example water (such as heated water) or an acidic solution or a basic solution. This is basically known from the prior art.
  • the containers 130 which are to be supplied with the cleaning fluid in the cleaning bath, can be guided through it "upside down" (as shown schematically here).
  • the container cleaning machine 100 can also include other devices for cleaning, such as further cleaning baths or spray devices for applying a cleaning medium or water or the like to the containers.
  • At least one, preferably a plurality of injector nozzles 111 to 113 are arranged in the cleaning bath 101, each of which can cause a flow of a cleaning fluid within the cleaning bath 101 in such a way that the cleaning fluid leaves the injector nozzle 111 to 113 in an outflow direction and is discharged in the direction of a container 130 transported through the cleaning bath.
  • a flow of cleaning fluid is effected by means of the injector nozzle 111 - 113 in the direction of the container to be cleaned, so that it is not only drawn by the cleaning fluid 140 within the cleaning bath, but also an additional cleaning effect due to the acting forces due to the applied flow the surface of the container is exerted.
  • the at least one injector nozzle 111 to 113 is connected to a fluid circuit 114, which mixes the cleaning fluid 140 in the cleaning bath 101, in order to be supplied with the cleaning fluid.
  • a fluid circuit 114 which mixes the cleaning fluid 140 in the cleaning bath 101, in order to be supplied with the cleaning fluid.
  • the container cleaning machine further comprises one or more suction devices 131 to 133, via which cleaning fluid 140 can be sucked out of the cleaning bath 101.
  • the suction units 131 to 133 can be designed as pumps and feed the extracted cleaning fluid 140, for example, to a collecting container 103, via which it is then fed via line 115, for example to the fluid circuit 114, optionally after filtering and/or after cleaning to remove contaminants and in particular labels removed from the containers, can be fed to be used again in the cleaning bath for cleaning containers.
  • the injector nozzle 111 and the suction 131 are arranged relatively such that the outflow direction of the flow from the injector nozzle 111 runs in the direction of an outflow opening of the injector nozzle 111 to the suction 131.
  • This relative arrangement can be implemented between an injector nozzle and a suction.
  • the transport device runs between the injector nozzle 111 and the suction 131, so that in some embodiments It can be provided that the transport device 102 extends through the cleaning bath 101 in such a way that the injector nozzles 111 to 113 (if a plurality is provided, but in any case at least one injector nozzle 111) are arranged on one side of the transport device are and the one or more suction devices 131 to 133 are arranged on the opposite side of the transport device.
  • Fig. 2 shows a further schematic view of a cleaning bath 101 of a container cleaning machine, as already referred to Fig. 1 was described.
  • the containers 130 are guided in receptacles 221 through the cleaning bath 101 and preferably also through the entire container cleaning machine 100.
  • Such recordings are generally known. They include an inflow opening 222, which usually coincides with the opening of the container 130 to be cleaned, and an outflow opening 223, which is located on the opposite side of the receptacle, so that it is in the area of the bottom of the container.
  • the outflow opening 223 can be realized by perforating the bottom of the receptacle 221, particularly if no large (larger than 1cm 2 ) contamination of the container is to be expected.
  • These receptacles 221 ensure safe transport of the containers in the container cleaning machine and at the same time cleaning fluid can flow around the containers in these receptacles.
  • the outflow direction 271 to 273 of the cleaning fluid from the injector nozzles 111 to 113 is selected so that it corresponds to a transport plane T 1 to T 3 in the area in which the respective injector -Nozzle 111 to 113 caused flow of cleaning fluid hits the container, includes an angle ⁇ 1 to ⁇ 3 .
  • This can be achieved reliably by using receptacles 221 and ensures that a targeted flow of cleaning fluid into the receptacles 221 is effected.
  • this embodiment and in particular the arrangement of the injector nozzles such that an angle is formed between the transport planes T 1 to T 3 and the respective outflow direction 271 to 273 can also be present in embodiments in which no previously described receptacles 221 are provided .
  • the angle between the outflow direction 271 to 273 and the transport plane of a container in the transport device in a region in which the flow hits the container transported through the cleaning bath is preferably between 5 ° and 85 °. This ensures that the flow reliably flows around the container 130 even in the receptacle 221 and that a force acting tangentially along the surface of the container is also exerted on the container. This tangentially acting force and the force acting perpendicularly on the surface of the container can together promote a cleaning result of the container.
  • the angle is particularly preferably between 20° and 75° and in particular between 35° and 65°.
  • An angle of 45 ° +/- 10 ° has proven to be particularly advantageous because, when choosing the appropriate angle, the force acting perpendicular to the surface of the container and the force acting tangentially to the surface of the container are essentially the same size, which is what is to be achieved The cleaning result is even more beneficial.
  • Fig. 3 shows an embodiment of an injector nozzle based on the Venturi principle.
  • this is screwed, for example, via a screw thread 390 to or in a wall of the cleaning bath 301, with a supply line 311 being able to supply cleaning fluid to the injector nozzle 300 as part of the fluid circuit 314.
  • a pump 312 can be provided in the supply line 311 as part of the fluid circuit 314, which conveys cleaning fluid in the arrow direction 316 shown.
  • the injector nozzle 300 initially comprises a feed area along the illustrated direction of movement 316 of the cleaning fluid, which is essentially formed by the feed line 311 and includes an opening 319.
  • the cleaning fluid emerges from the supply line 311 and enters a feed area 313, which is at least partially open to the cleaning bath 301.
  • This means that the inner region of the intake area 313 is fluidly connected to the cleaning bath 301, so that cleaning fluid 317 from the cleaning bath 301 is drawn into the intake area 313 by the Venturi effect, which is caused by the cleaning fluid flowing in the direction 316.
  • the feed area 313 can be connected to the feed area or the feed line 311 via suitable connecting elements 315, which are shown in the cross-sectional drawing here can be seen, but do not completely seal off the intake area in a liquid-tight manner, so that, as already discussed above, cleaning fluid 317 from the cleaning bath 301 can penetrate into the intake area 313.
  • the feed area tapers in the flow direction 316 of the cleaning fluid, so that the diameter tapers from an initially large diameter, which is preferably at least 10%, particularly preferably at least 50% larger than the diameter of the outlet opening 319 of the feed area 311, to a smaller diameter.
  • This smaller diameter can optionally be larger than or equal to the diameter of the outlet opening 319 of the feed area 311.
  • An outlet region 320 can then be provided, the diameter of which increases from the tapered end of the feed region 313 to the outflow opening 321, from which a quantity of cleaning fluid 318 then emerges.
  • the amount of cleaning fluid 318 flowing out is greater than the amount of cleaning fluid 316 emerging from the outlet opening 319 of the feed area 311.
  • the amount of cleaning fluid 318 can be at least twice as large or at least three times as large or at least four times as large, preferably at least five times as large as the amount of cleaning fluid emerging from the outlet opening 319 of the feed area.
  • the injector nozzle is arranged pivotably mounted on an oscillating shaft.
  • the shaft can be designed as a hollow shaft that carries cleaning fluid and can alternatively or additionally have transverse bores, whereby cleaning fluid can be supplied to the injector nozzle.
  • the shaft represents part of the supply line 311 and is supplied with cleaning fluid via the pump 312.
  • the shaft (and thus the injector nozzle) is pivoted back and forth via a suitable drive, so that the outflow opening 321 accompanies the container to be cleaned in the transport direction for a short period of time and then returns to a starting position for treating a following container. This further improves the cleaning result.
