Definitions

  • the present invention relates to a device for cleaning boxes for beverage containers.
  • the invention will be described with reference to a bottle box cleaner, but it should be noted that the device according to the invention can also be used for cleaning other boxes for beverage containers, for example, boxes for cans and the like.
  • a device for washing or cleaning of containers is known.
  • This device has a second cleaning unit, which is provided for cleaning the interior of the device.
  • This second cleaning unit thus at least partially allows self-cleaning of the device.
  • a return channel for the cleaning agent is also provided in devices known from the prior art. If necessary, after passing through filter devices, the cleaning agent returns to the flow channel via this return channel.
  • the present invention is therefore based on the object to improve a self-cleaning process for a device for cleaning boxes. In addition, the removal of contaminated cleaning agents should be improved.
  • the inventive device for cleaning boxes for beverage containers has a housing and a bottom, wherein in an interior of the housing at least one is provided from the bottom limited first flow channel along which the boxes are moved by means of a flowing through this flow channel cleaning agent in a conveying direction.
  • at least partially separated from the first flow channel return channel is provided in which the cleaning agent is guided in a return direction, wherein the return channel is bounded by the bottom.
  • the bottom in the region of the return channel preferably has downwardly directed discharge openings for discharging the cleaning agent.
  • a flow channel delimited by the bottom is understood to mean a flow channel that is bounded by the bottom in one direction and, for example, in a second direction by a housing wall or an intermediate wall.
  • a total of a channel for the cleaning agent is formed and this detergent flows through this channel and thereby moves the crates with.
  • the bottle crates are treated by the cleaning agent, for example prepurified.
  • an immersion bath is formed by the flow channel, along which the crates are guided.
  • the return duct is also bounded by the floor, for example by the floor and two side walls.
  • the inventive arrangement of discharge openings in the return channel it is possible to dissipate impurities also on the return path.
  • a filter is often arranged in front of the return channel, but this filter is often chosen so coarse to ensure the necessary flow cross sections that fine dirt particles can get into the return channel. By means of the bottom openings according to the invention, these particles can also be removed from the return channel.
  • a return channel can also be provided with recesses and openings preferably a return pipe ie the channel can be designed as a tube.
  • a channel is thus understood to mean both a channel open to one side and a closed tube.
  • discharge openings would not be provided in the bottom, but these openings would be arranged in the said return pipe.
  • This pipeline can in turn lead to branching channels.
  • the openings in the return channel are closable or to the openings close to discharge lines and valves.
  • the device preferably has a cleaning unit for self-cleaning of the device.
  • the present invention is further directed to a device for cleaning boxes for beverage containers, wherein the device comprises a housing and a bottom and wherein in an interior of the housing at least one of the bottom limited first flow channel is provided along which the boxes by means of a be moved by this flow channel flowing detergent in a conveying direction. Furthermore, a return passage, which is at least partially separated from the first flow passage, is provided, in which the cleaning agent is guided along a return direction, wherein the return passage is bounded by the bottom in one direction.
  • the device has a cleaning unit for self-cleaning of the device, wherein the cleaning unit has a plurality of cleaning nozzles.
  • At least one of these cleaning nozzles has a stationary body (arranged opposite the device) and a spray head arranged rotatably relative to this body.
  • the spray head it is also possible for the spray head to be arranged stationary relative to the base body, but to permit an exit of a cleaning agent entering it in substantially all directions lying in the circumferential direction. It is possible that on the round body a spherical head is arranged with a plurality of openings and from this head, the cleaning agent passes through these individual openings and thus also exits in all directions with respect to the spray head.
  • Such spray heads are also referred to as static spray balls and also allow radiation of the cleaning agent in all radial directions of the cleaning nozzle. This spray ball can additionally be made rotatable.
  • the said cleaning unit is preferably designed as a separate cleaning unit, that is to say the device has a first cleaning unit for cleaning the boxes itself on and a second cleaning unit for cleaning the interior of the device.
  • a bypass could be arranged in a supply line for the cleaning unit and optionally different cleaning agents are sent to the cleaning unit. More specifically, it would be possible for the same cleaning nozzles, which in normal operation clean the boxes, to be cleaned in a special cleaning cycle for the device, for example for the housing inner walls or the bottom of the device.
  • the body of the cleaning nozzles is stationary and thus are from the DE 10 2004 058 150 A1 swiveling cleaning nozzles not necessary.
  • the cleaning nozzles according to the invention can be produced much cheaper and nevertheless allow a largely comprehensive interior cleaning of the device according to the invention.
  • the individual cleaning nozzles can be arranged at the most different areas in the interior of the device and in particular such that they are also suitable for a floor cleaning.
  • a particularly favorable internal cleaning of the device according to the invention is possible.
  • the cleaning nozzles are arranged pivotally or rotatably in their entirety.
  • two different and separate cleaning units are provided, one cleaning unit is used to clean the boxes and the other cleaning unit for internal cleaning of the entire device.
  • the rotatable arrangement of the spray head according to the invention relative to the base body allows all-round cleaning, even if the base body is not moved.
  • the return direction and the conveying direction are opposite, that is, the bottle crates are moved in the first conveying direction, which is preferably rectilinear and the cleaning agent is returned in the return direction, which runs counter to the conveying direction.
  • the discharge openings are arranged in the return channel in itself funnel-shaped downwardly narrowing first bottom depressions. These bottom depressions allow a more efficient removal of the remaining after a cleaning process in the device cleaning agent.
  • the depth of the bottom recess increases in the return direction. Preferably, the depth increases steadily, with most preferably the opening at the lowest point of the bottom recess is arranged.
  • the openings are arranged such that the cleaning agent can pass through the opening in the return direction. In this way, a particularly simple removal of the liquid is achieved without diverting the flow direction.
  • the nozzle is arranged so that the liquid jets generated by the respective nozzle can impinge obliquely on the bottom depression or the walls of this bottom depression.
  • the bottom recess thus acts as a collector for remaining after a cleaning process liquid.
  • the device has a second flow channel and the return channel is arranged between the first flow channel and the second flow channel.
  • the beverage crates are guided in two parallel rows through the immersion bath and the respective recirculating streams are jointly, that is, through a common return channel out.
  • further return channels can also be provided on the respective outer sides of the flow channels.
  • the device has separation walls for separating the individual channels, that is to say the flow channels and the return channel.
  • These partitions are particularly preferred closed walls and fixed to the ground.
  • the partitions may in principle also have closable openings.
  • the discharge openings according to the invention make it possible to carry out the partitions closed in their entirety, which is not only less expensive is, but also increases the reliability, since for example by the operator closing the partitions can not be forgotten.
  • the base in the region of the flow channel to drain openings for discharging the cleaning agent.
  • these discharge openings are also preferably arranged in funnel-shaped downwardly tapering second bottom depressions, which also act here as collection devices arranged.
  • the depth of the second bottom depressions increases in the conveying direction. That is, the depth increases in the opposite direction in contrast to the first bottom recesses in the region of the return channel.
  • the second bottom recesses are offset from the first bottom recesses in the flow direction.
  • the bottom in an end region of the flow channel has a further discharge opening for discharging the cleaning agent.
  • This further discharge opening serves to discharge liquid, which drops when transporting the crates, for example, in higher conveyor paths.
  • dirt is removed from a (circulating) filter belt filter.
  • This further discharge opening is preferably arranged in a substantially symmetrical base recess, particularly preferably in its center.
  • the spray head of the nozzle has two separate outlet openings. Particularly preferably, these two outlet openings are arranged on opposite sides of the spray head. One of the two outlet openings allows a liquid outlet to the side and obliquely downwards and the other outlet opening allows the liquid to escape to the side and obliquely upward.
  • the spray head is designed such that the exiting liquid with respect to a longitudinal direction of the nozzle in an angular range between 0 ° and 180 °, preferably between 20 ° and 160 ° can escape.
  • the liquid can be directed to the respective adjacent walls in a space surrounding the spray head area.
  • the cleaning nozzle is made in its entirety from a plastic. It is particularly preferred to use PTFE as the plastic. Such a nozzle is cheaper to manufacture than metal nozzles commonly used for such purposes. Also, in such a plastic nozzle, the spray head can be moved more easily with respect to the nozzle body by the cleaning agent flowing therethrough. Preferably, the spray head of the nozzle is mounted relative to the main body of the nozzle by means of a sliding bearing. This also achieves a particularly simple embodiment of the spray nozzle. It is further noted that a plastic nozzle is also relatively insensitive to calcifications. More specifically, it has been shown in elaborate studies that in particular high-precision metal nozzles are less suitable for the present purpose. Conversely, when using the nozzle, it is also not crucial whether the exit of the jet is precisely defined with respect to its direction.
  • the sliding bearing allows a certain bearing clearance of the spray head relative to the spray nozzle.
  • the flow paths for the cleaning agent in the interior of the spray head are designed such that even particles present in the cleaning fluid can escape through the nozzle. All too fine nozzles would prevent passage of particles present in the cleaning fluid and would therefore be rather unsuitable for the present application.
  • the intended bearing clearance allows a smooth running of the spray head relative to the base body and also a smooth running, if, for example, foam passes through this spray head. Any loss of accuracy in the spraying process may be accepted in view of the intended application.
  • the depth of at least a first bottom recesses and preferably all bottom recesses increases in the conveying direction. This appears initially unusual, since the first bottom depressions is arranged in the return channel and in this return channel, the flow direction of the water in the direction opposite to the conveying direction and therefore deepen the first bottom wells against the flow direction. However, this procedure offers considerable advantages, which will be explained in more detail with reference to the figures.
  • the present invention is further directed to a floor for a device of the type described above.
  • This floor has a plurality of discharge openings and discharge openings, wherein these discharge openings and discharge openings are respectively arranged in funnel-shaped first and second bottom recesses of this floor.
  • the first bottom depressions are arranged one behind the other in a longitudinal direction of the bottom and also second bottom depressions are arranged one behind the other in the longitudinal direction of the bottom.
