Definitions
- the invention relates to a labeling machine for applying labels to vessels, for example bottles or cans, using cold glue, comprising a glue supply device.
- the supply of cold glue required for labeling takes place discontinuously, for example by filling in cold glue obtained from the glue manufacturer and filled into storage and / or transport containers.
- the cold glue typically used consists of 50 to 80% water, which in principle can also be obtained as a raw material in the work area of the labeling machine and is therefore unnecessarily transported from the glue manufacturer to processing. This creates significant unnecessary transport costs and environmental concerns.
- the finished cold glue also has a limited shelf life, for example about 6 months from production. When the cold glue is not used up, it has to be disposed of, which is disadvantageous both in terms of price and ecologically.
- due to the short shelf life of the cold glue especially after the storage and transport containers have been opened, the containers cannot be too large, which contributes to the amount of packaging waste and the frequency of deliveries.
- the shelf life can be improved in principle by adding preservatives, but this is also associated with costs and ecological concerns, so that it is preferable to keep the amount of preservatives used low.
- the glue supply device for producing the cold glue is designed from several components, in particular at least one liquid and one solid component, so that the cold glue required for applying the labels is processed, especially mixed together , the components can be manufactured.
- One advantage of such a labeling machine is that the transport volume for the solids or concentrates required for a certain amount of cold glue is significantly lower than for this amount of finished cold glue. Water, which makes up a large proportion of the cold glue, can then be obtained from the water supply that is usually available on the factory premises fed to the labeling machine. This saves transport costs and storage costs.
- preservatives do not necessarily have to be added or only a smaller amount of them and larger packs (based on the effective amount of cold glue) can be used without the risk of glue. Significantly increase rejects. This also means that there is less packaging waste.
- the claimed device is advantageous both for cost reasons and from an ecological point of view.
- Cold glue can therefore be freshly produced at any time on site, i.e. on the company premises in the area of the machines where the labeling operation takes place, and used and consumed promptly, if necessary even immediately after production.
