Title: Packaging system for producing pouches

Description:
FIELD OF THE INVENTION 
     The invention relates to a packaging system for producing pouches having a compartment and made from a first water-soluble foil and a second water-soluble foil. 
     BACKGROUND OF THE INVENTION 
     The invention is based on the insight that the known packaging systems are not able produce high quality pouches holding different materials. 
     SUMMARY OF THE INVENTION 
     The invention has the objective to provide an improved or alternative packaging system. This objective is reached by a packaging system for producing pouches having multiple compartments and made from a first water-soluble foil and a second water-soluble foil, which packaging system comprises;
         a mould conveyor to move multiple moulds in a conveying direction along an endless trajectory, such as a circular trajectory, wherein each mould faces outwards and has a first suction chamber, a second suction chamber, and a support surface surrounding and extending between the first and second suction chamber,   a suction device configured to suck the first foil into the first suction chambers and the second suction chambers, and wherein the mould conveyor moves each mould along;
           a first foil supplying device configured to position the first foil on the support surface of the mould and over its first and second suction chamber, after which the suction device sucks a first part of the first foil extending over the first suction chamber into the first suction chamber to form a first compartment of the pouch and sucks a second part of the first foil extending over the second suction chamber into the second suction chamber to form a second compartment of the pouch,   a powder filling device configured to fill the first compartment with a powder,   a further filling device configured to fill the second compartment with a further powder or a liquid,   a second foil supplying device configured to position the second foil on the first foil and over the filled first compartment and the filled second compartment in order to from the pouch which holds the powder in the first compartment and the liquid or further powder in the second compartment, and wherein
               the powder filling device comprises;

     The powder filling device is configured to fill the first compartment with the powder in a very accurate manner. Due to this, no or little powder will end up on the first foil located outside the first suction chamber. This is essential because if (too much) powder is located on the parts of the foil covering the support surface of the mould, this has a negative effect on the sealing between the first and second foil. A good sealing is required to avoid that the content of the first and second compartment remain separated from each other and to avoid that the pouches will leak from the first and second compartment to the outside world. In addition to this, it is essential that during the filling of the first compartment, no (or very little) powder ends up in the second compartment in order to avoid contamination.

The heat of the second heated roller  92  already takes care of part of the sealing process. The third heated roller  93  rolls over the second foil  6  in order to finish the sealing process. 
     The  FIGS. 13A-H  show operation steps that are performed on one of the moulds  8 .  FIG. 13A  shows one mould  8  of the row  15  of  FIG. 3 . Said mould  8  is moved along the endless trajectory  10  by the mould conveyor  7 , more specifically the drum  40 . In  FIG. 13B , the first foil  5  is positioned on the support surface  13  of the mould  8  and over its first and second suction chamber  11 ,  12  by the first foil supplying device  16 . After that, the first part  21  of the first foil  5  is sucked into the first suction chamber  11  to form the first compartment  3  of the pouch  2  and the second part  22  of the first foil  5  is sucked into the second suction chamber  12  to form the second compartment  4  of the pouch  2  ( FIG. 13C ). 
     The powder filling device  25  is used to fill the first compartment  3  with the powder  26 . Due to the accurate filling by the powder filling device  25 , no or little powder  26  will end up on the first foil  5  located outside the first suction chamber  11 . This is essential because if (too much) powder is located on the parts of the foil covering the support surface  13  of the mould  8 , this has a negative effect on the sealing between the first and second foil  5 ,  6 . A good sealing is required to avoid that the content of the first and second compartment  3 ,  4  remain separated from each other and to avoid that the pouches will leak from the first and second compartment  3 ,  4  to the outside world. In addition to this, it is essential that during the filling of the first compartment  3 , no (or very little) powder  26  ends up in the second compartment  4  in order to avoid contamination. 
     The further filling device  28  is used to fill the second compartment  4  with the liquid  29  ( FIG. 13E ). 
     In  FIG. 13F , the second foil  6  is positioned on the first foil  5  and over the powder  26  in the first compartment  3  and the liquid  29  of the second compartment  4  by the second foil supplying device  17 . The seal between the first foil  5  and the second foil  6  is created by the sealing unit  31  which is integrated in the second foil supplying device  17 . The first cutting unit  37  and the second cutting unit  38  of the cutting device  36  make subsequently the cuts along the first cutting slits  65  and the second cutting slits  66 , respectively ( FIG. 13G ). 
     In  FIG. 13H , the pouch  2  holding the powder  26  in the first compartment  3  and the liquid  29  in the second compartment  4  is removed from the mould  8 . 
     The  FIGS. 14A-C  show views in perspective of the packaging system  1 . In  FIG. 14A , the drum  40  is located in the operating position  82  relative to the main frame  81 . In  FIG. 14B , the drum  40  is partly removed from the packaging system  1 . In  FIG. 14C , the drum  40  is completely removed from the packaging system  1 . The drum drive  45  is visible. The drum drive  45  comprises a gear wheel  68  which engages a gear rack  69  (see  FIG. 15B ) provided on the drum  40 . Also the suction device  14  is shown. 
     The  FIGS. 15A-B  show views in perspective of the drum  40 . The drum  40  is only supported by the drum frame  83 . The drum frame  83  comprises first coupling members  84  which can be coupled with cooperating second coupling members  85  connected to the main frame  81  when the drum  40  is positioned in the operating position  82 . The coupled first and second coupling members  84 ,  85  hold the drum  40  in the operating position  82 . 
     The drum  40  is provided with drum suction openings  54  located in a second circular configuration  43  ( FIG. 15B ). Each drum suction opening  54  is in fluid communication with the first and second connector of row  15  of moulds  8 . In  FIG. 15C , also the suction device  14  is shown. The suction device  14  is positioned relative to the drum  40  as it would when the drum  40  is located in the operating position  82 . 
     The  FIGS. 16A and 16B  show the suction device  14 . The suction device  14  comprises a suction mouth  48  which is in fluid communication with a low pressure via a fluid duct  73 . In use, the suction device  14  is located at a fixed suction position  50  relative to the drum axis  41 . The drum suction openings  54  are positioned to be received by the suction mouth  48  when the drum  40  is rotated. The first and second suction chambers  11 ,  12  of each row  15  of moulds  8  are in fluid communication with one of the drum suction openings  54 . For each row  15  of mould  8  its suction opening  54  is positioned relative to the suction mouth  48  such that said suction opening  54  is received by the suction mouth  48  after said row  15  of moulds  8  has passed the first foil supplying device  16  and before said mould has reached the powder filling device  25 .
