- Cleaning machines for containers in particular container cleaning machines for bottles used in the beverage industry, are well known. For example, a not inconsiderable proportion of the beverages that are sold are offered in reusable containers made of glass or plastic, which is why the bottles and similar containers have to be cleaned before each use cycle. To clean these containers for their reuse, the above-mentioned cleaning machines are used within the bottling plants, which are known to those skilled in the most varied designs.
- Such container cleaning machines have several treatment zones between a container task and a container discharge, through which the bottles or containers are moved with a machine-internal conveyor.
- Widespread are embodiments in which the containers are individually received in so-called container cells or bottle cells or bottle baskets of the machine-internal conveyor during the cleaning phase and several of these container cells or bottle cells are arranged in a row.
- the bottle cells are held on endlessly circulating transport chains, by which they are guided through several treatment zones or treatment stations that follow one another in the transport direction. As a rule, these transport chains are permanently driven.
