Description

The present invention relates to a spray station of a cleaning machine for cleaning containers according to the preamble of claim 1. Furthermore, the present invention relates to a cleaning machine with at least one such spray station.

A not inconsiderable proportion of the beverages entering the market is offered in reusable glass or plastic containers. The containers to be cleaned with the injection station according to the invention are preferably reusable containers. To clean these containers for their reuse, so-called container cleaning machines are used within the bottling plants of the beverage industry. Such cleaning machines for cleaning reusable containers are known in the art in various designs.

Versions are widely used in which the containers are received in so-called bottle cells. Several of these bottle cells are arranged in a row of so-called bottle carriers. These bottle carriers - or container baskets called - in turn are held on two endless circulating transport chains, by which they are guided by several, in the transport direction successive treatment stations. As a rule, these transport chains are permanently driven.

The supply of the container to a cleaning machine is done by a so-called task, the removal of the container by a so-called levy. The period between two feeds or deliveries is called the work cycle. The transport chain is maintained for an extended period of time, i. driven at a preferably constant speed over a plurality of work cycles away.

The treatment of the container within the cleaning machine is carried out essentially in so-called immersion or Laugebädern different temperatures and - to complete the treatment - within so-called spray zones, which comprises at least one, preferably several in the transport direction in series injection stations. Within these spray zones u.a. the interior of the corresponding container received in the container basket repeatedly ejected to completely remove foreign bodies or even lye residues from the interior of the container. Furthermore, at the spray stations but also the outer circumferential surface of the container is cleaned, in particular cums. For complete cleaning of the container sufficiently large periods for Laugebehandlung and / or the spray zones are needed.

Within the cleaning machines, several types of spray nozzles have become known, e.g. for rotating sprays or a rotating cleaning jet, in which the spray jet by a rotating valve or nozzle assembly follows the container, immovably rigid sprays which are fixed and stationary, and movable spraying, which perform on a movable, a forward and backward movement element are arranged and thus the transport movement of the container at least temporarily - namely preferably during the loading of the corresponding container with the cleaning jet - follow.

It must be ensured in particular that after passing through a container through the spray zones no residues of the sometimes aggressive treatment liquid or cleaning liquid, for example, the treatment liquid of the applied Laugebäder, (more) attached to or in the respective container.

As mentioned above, the containers are often reusable containers, which are to be filled again with a liquid filling material after the cleaning. Remains of treatment or cleaning liquid in the container to be refilled then it should be avoided.

In the figures, 1 is a cleaning machine for cleaning containers 2 or the like is shown in a side sectional view. In particular, the containers 2 It is designed as a reusable container, for example, PET or glass bottles. In the case of a housing 3 formed interior 4 the cleaning machine 1 is a transport system 5 provided with which the container to be cleaned 2 be moved through different treatment zones, from a bottle inlet 6 (Task), inter alia, by a first, a cleaning liquid, such as alkaline water containing immersion bath 7 , then through a second, a cleaning liquid, such as lye, containing immersion bath 8th and by various spray stations provided in a spray zone 9 , in which each of a spraying of the bottle outer and inner surfaces with spray jets of cleaning fluids and finally done with pure water, so that the cleaned container 2 with the transport system 5 finally to the bottle outlet (delivery) or to the bottle delivery 14 reach.

The transport system 5 consists in the manner known to those skilled in a variety of transport direction A adjoining bottle baskets moving with circulating transport chains 15 , each of which at the in 2 By way of example, embodiment shown greatly simplified shown three perpendicular to the transport direction A juxtaposed bottle cells or container cells 16 having. In every container cell 16 is a container, especially a bottle 2 , Preferably centered so recorded that this with its container mouth 2.1 essentially congruent with an opening 17 at the otherwise substantially closed end of the respective container cell 16 lies.

The transport system 5 has several deflections in the 1 generally with 18 - 22 are designated and of which the diversion 19 completely within the dipping bath 8th located. When passing the diverter 19 are the containers formed as bottles 2 with its bottle axis, in particular bottle axis FA oriented radially or approximately radially to the horizontal axis of this deflection, in such a way that the container mouths 2.1 and also the openings 17 the container cells moving past there 16 facing this axis.

In the 1 is the movement or transport direction of the container baskets 15 in the area of spraying relative to the spray station 9 with the arrow A indicated. Each container basket 15 forms several receptacles or container cells 16 necessary for receiving the respective container 2 serve and perpendicular to the transport direction A of the transport system 5 consecutively in the respective container basket 15 are formed. Such container baskets 15 are also referred to as bottle baskets.

The spray station according to the invention 9 the cleaning machine 1 for cleaning the containers 2 includes at least one spray nozzle 30 with at least one cleaning jet 31 for applying the in the transport system 5 , in particular in the container basket 15 with his respective after bottomed container mouth 2.1 taken container 2 with a cleaning and / or treatment liquid. In this case, the orientation of the through the spray nozzle 30 generated cleaning jet 31 relative to the cleaning container 2 in the area of the spray station 9 during the loading of the container 2 be predetermined with the cleaning liquid.

More in detail, the injection station according to the invention 9 in particular for internal injection or internal cleaning of the containers 2 be educated.
