Description

The invention relates to a blister packaging machine with a filling station for filling cup-like depressions of a bottom foil with a filling material, wherein the filling station is arranged in an interior of a containment. Furthermore, the invention relates to a method for cleaning such a blister packaging machine.

In the prior art blister packaging machines are known, which are designed for packaging objects in blister packs. Here, e.g. made of a thermoformable band blister packs, the blister packs having well-like depressions into each of which an article or a product, such as e.g. a pharmaceutical tablet is inserted. Subsequently, the filled cup-like or shell-like depressions are sealed airtight with a sealing film or cover film, for example by gluing or welding.

Usually, a blister packaging machine has a forming station in which a bottom film is provided with cup-like or cup-shaped depressions by means of a forming tool or the like. Here, the depressions are molded into the bottom films accordingly. Subsequently, the shell-like or cup-like depressions are filled in a filling station of the blister packaging machine with an article or a corresponding filling material. After the supply of the filling material, the filled bottom film is fed to a sealing station of the blister packaging machine, so that the bottom film is supplied with a cover film and sealed with the bottom film, so that the filled product is enclosed in the well-like depressions.

In addition, for example, under the name CP 500 a blister packaging machine of MediSeal GmbH is known.

Furthermore, blister packaging machines are known which have a so-called containment, wherein within the containment the wells or receptacles of a bottom foil with a filling material, for. As pharmaceutical products, are filled.

A containment blister packaging machine is used, for example, for packaging tablets such as tablets. Hormone preparations or the like, used, for example, to protect the burden on the operator from dust and the production environment from permanent contamination or accumulation of components of the drugs.

The containment of a blister packaging machine is designed, for example, as an insulator, as a lock or as RABS (Restricted Area Barrier System). Alternatively, the containment is also designed as a chemical / pharmaceutical or biotechnical safety workbench. Such devices with a containment are adapted to treat sterile goods, which are not allowed to get contaminating particles from the outside or into the material to be treated, or to treat pharmaceutical goods in which no particles are allowed to enter the external environment.

Based on this prior art, the object of the invention is to improve the handling of a containment blister packaging machine in a simple manner.

This object is achieved by a blister packaging machine with a filling station for filling cup-like depressions of a bottom foil with a filling material, wherein the filling station is disposed in an interior of a containment, which is further developed in that a controllable and movable cleaning device for the containment is arranged in the containment wherein a control device is connected to the cleaning device, so that the movements of the cleaning devices in the interior of the containment for cleaning the interior and for cleaning the filling station or parts thereof are controllable or controlled, wherein the cleaning device has at least one movable and controllable cleaning nozzle, wherein the cleaning nozzle can be acted upon by a cleaning medium from a cleaning medium reservoir, and wherein the cleaning device has at least one movable and controllable blown air nozzle, wherein the at least one Blasluftdüse with a drying medium, in particular air, from a drying medium supply can be acted upon.

The invention is based on the idea that for cleaning a blister packaging machine, in particular for cleaning the interior of the containment, in which a filling station is arranged, a cleaning device, in particular in the form of a cleaning robot with a movable arm, is provided, so that more difficult in the containment accessible places are accessible and thereby further an operator-free, automatic cleaning of the interior of the containment and the filling station provided therein, eg a metering device is enabled. For example, on a movable arm of a cleaning robot, e.g. a flushing device and / or drying device mounted, whereby the containment is cleaned inside in a controlled manner.

Due to the controlled guidance of the movements of the cleaning device with this control device, the internals, eg a filling station, are targeted bypassed inside the containment, whereby it is still possible due to the controlled guidance of the movement of the cleaning device predetermined locations in the interior of the containment targeted and automatic Way to clean. As a result, the cleaning process as a result of predetermined cleaning steps and cleaning programs is advantageously reproducible, so that after the production of a batch of filled blister packs, a standardized cleaning process is performed so that subsequently the blister packaging machine is operated for a production of blister packs with another filling.

In addition, the cleaning time and / or the drying time can be reduced by the controlled, in particular programmed, cleaning of the interior of the containment. In addition, the need for cleaning medium, such as water and cleaning agents as well as on a drying medium, such as dry air, is reduced accordingly, which also reduces the cost of the cleaning process.

In particular, the blister packaging machine is designed for the production of pharmaceutical blisters and optionally their cartoning. In this case, the well-like depressions of a provided, in particular continuous, bottom foil are filled, for example, with solid products for peroral application, such as, for example, tablets, dragees, capsules and the like. The filling of the wells of the bottom foil with these solid products takes place here in a shielded against the environment of the machine containment. The containment is here preferably designed as RABS (Restricted Area Barrier System) or insulator or the like.

By means of the cleaning device, it is also possible to carry out both a wet cleaning of the interior of the containment and a dry cleaning of the containment.
