Definitions

  • the invention relates to a sealing device for sealing packages of the type specified in the preamble of claim 1 and to a method for sealing packages by means of such a device.
  • detergents or dishwashing detergents for domestic use are packaged in the form of powders or liquids in water-soluble packaging.
  • the packages consist of water-soluble film and contain a unit dose of the washing or rinsing agent as a product.
  • the filled and sealed packaging unit is placed in the washing machine or dishwasher. Upon contact with water, the film packaging dissolves and releases the contents in the quantity provided.
  • a base film and a cover film are used, wherein the base film or the cover film are formed from a water-soluble film web.
  • the base film is thermoformed under the action of heat and vacuum in corresponding matrices.
  • the molding process creates depressions in the base film, which are filled with the filling material.
  • a cover sheet is sealed onto the base film.
  • the sealing of both films the filling material contained in the molds is enclosed.
  • the sealed packaging units are separated from the coherent film webs so that they can be used individually by the user.
  • a water seal is also possible.
  • water is applied to the cover sheet by means of a moistening unit, for example a felt roll.
  • the moistened felt roll rolls on the water-soluble film web, whereby its surface is dissolved.
  • the covering film with a loosened surface is then pressed onto the prepared base film by means of a pressing device, the dissolution of the film surface causing a sealing.
  • Arrangement and method of this type are for example from the GB 2 475 538 A known.
  • a disadvantage of such a water-sealing process is that the amount of water applied is difficult to meter by means of the felt roll. If the water application to the water-soluble film is too great, followed by a too pronounced dissolution of the film and thus an undesirable reduction in the film thickness. As a result, the film or later the individual packages may tear in the further course of production. If, however, the amount of water applied is too small, there will be insufficient dissolution of the film surface, so that the two films do not connect properly. The packaging can consequently be leaking. But even if it is possible to set and maintain a suitable amount of water for the current operations, an adaptation to changing conditions is difficult to achieve. In the applicator roll or felt roll saturation is observed, which leads to a change in the order amount and also to contamination of the roller during the production process. This results in a deterioration of the seal. A regular machine standstill for roll change is inevitable.
  • the invention has the object of developing a generic sealing device such that an improved liquid application is achieved on the water-soluble film web.
  • the invention is further based on the object of specifying a method for sealing packages, by means of which a better metered moistening of the water-soluble film web can be carried out.
  • the moistening unit of the sealing device as a spraying device for contactless spraying of the liquid on the formed water-soluble film web and positioned at a distance from the water-soluble film web.
  • the water-soluble film web is first fed to the device, wherein a base film and / or a cover film of the packaging is formed from the water-soluble film web.
  • the spraying device which is positioned at a distance from the water-soluble film web, water-containing liquid is sprayed onto the water-soluble film web.
  • the cover film is guided onto the base film and pressed with this by means of a pressing device in the wetted state with the liquid and sealed.
  • the invention is based on the basic idea that no mechanical contact of the film with the moistening unit is dispensed with, and that, instead, the water-containing liquid intended for dissolving the film surface is sprayed in contactlessly.
  • the application of the liquid can be adjusted so precisely and repeatably in terms of quantity and areal distribution by means of the spraying device that the desired degree of surface solution is exactly hit, and consequently a uniform sealing takes place along the entire film surface. This can also be reacted in a simple manner to changing boundary conditions, such as batch fluctuations in the film thickness or the like. In the production process.
  • Another advantage is that the moistening unit is not in direct contact with the cover sheet, so that a mechanical impairment is avoided.
  • the conveying speed of the film determines the rotational speed of the rolling thereon roll of felt and thus very difficult to control or adaptation of the water supply
  • the delivery rate of the sprayer completely independent of the movement of the film.
  • the injection process and thus the moistening of the film can be easily turned off without the cover sheet thinning excessively under an excessively high amount of liquid or even ruptures. Re-commissioning can be done without replacing the slides.
  • This also includes the possibility of being prepared at the previous standstill, but first seal off unsealed packaging units without creating the scrap. The risk of machine pollution is reduced.
  • the spraying device comprises an electromechanical spraying system with a series of outlet nozzles for non-contact spraying of the liquid onto the water-soluble film web.
  • This may be a bubble jet or piezo print head known, for example, from inkjet printheads.
  • it is preferably an electromechanical spray system with solenoid valves, whereby water or water-containing liquids in a suitable amount, speed and distribution over a suitable distance high quality can be applied to the film web.
  • the electromechanical valves allow the generation and application of sufficiently large drops of water. In the water supply, a suitable high pressure can be applied, which then larger spraying distances can be bridged.
  • the opening times of the valves and the number of spray pulses are adjustable and can be adapted to the film speed.
  • the nozzles are available with suitable diameters and can be selected depending on the application.
  • an electromechanical spray system allows in particular a variety of adjustments to the particular situation. For example, it is not limited to spray the respective film over the entire surface with liquid. Rather, the individual outlet nozzles or solenoid valves can also be individually controlled and actuated individually, which allows the dispensing of the liquid in the form of any defined patterns. For example, it is possible to limit the moistening to certain sealing contours, while the remaining film sections remain dry. As such, the film is protected, while at the same time sensitive fillings are protected from moisture. In the case of machine downtime and restart, the spray head can be swiveled to re-humidify specific areas. In this way, following a machine downtime, a virtually seamless seal can be achieved without powder or other ingredients escaping and causing dirtying the machine. Bad parts can easily be discarded without good parts being affected.
  • the sealing device comprises a squeegee having a doctor edge for wiping off the excess liquid from the water-soluble film web. Excess liquid may be removed from the cover sheet by means of the squeegee. The liquid remaining on the cover foil is distributed by means of the doctor blade in such a way that a uniform liquid film is formed on the cover foil, which improves the homogeneity of the foil seal.
  • a gap having a defined gap width is formed between the doctor edge and the film web.
  • the squeegee comprises a suction device for sucking off the excess liquid stripped off the squeegee edge.
  • the stripped and then aspirated liquid can for example be fed into a separate collection container or back into the liquid container.
  • the injection device is surrounded by a housing, wherein on the housing a spray window for the directed application of the liquid is formed on the water-soluble film web.
