Definitions

  • the invention relates to a sealing device for sealing packaging according to the preamble of claim 1 and a method for operating such a sealing device.
  • Detergents or dishwashing detergents for domestic use are increasingly being packaged in water-soluble packaging in the form of powders or liquids.
  • the packaging is made of water-soluble film and contains a unit dose of detergent or dishwashing liquid.
  • the filled and sealed packaging unit is placed in the washing machine or dishwasher. Upon contact with water, the foil packaging dissolves and releases the contents in the intended quantity.
  • a base film web and a cover film web which are formed from water-soluble films, are used.
  • the base film is usually deep-drawn into appropriate matrices under the influence of heat and vacuum.
  • the molding process creates troughs in the base film, which are filled with the filling material.
  • a cover film is then sealed onto the base film. By sealing both films, the filling material in the molds is enclosed. Finally, the sealed packaging units are separated from the connected film strips so that they can be used individually by the user.
  • water sealing can also be considered for sealing such packaging.
  • moistening units with a felt roller are used, by means of which water is applied to the cover film.
  • the moistened felt roll rolls on the water-soluble film web, which dissolves its surface.
  • the cover film with a dissolved surface is then pressed onto the prepared base film using a pressure roller, with the dissolution of the film surface causing a seal.
  • Arrangements and procedures of this type are, for example, from GB 2 475 538 A known.
  • flatbed machines are used in which format plates with molded matrices are moved around in a manner similar to a conveyor belt and thereby carry out a horizontal movement during the process steps relevant for deep drawing, filling and sealing.
  • larger output quantities per unit of time are possible because one or more format plates, each with several matrices, can go through a process step at the same time.
  • the latter requires that the individual process stations are comparatively far apart from one another along the horizontal movement path.
  • the electromechanical spray system moistens the cover film web on the circumference of the pressure roller, i.e. just before the sealing point. Nevertheless, a certain section of film remains between the moistening point and the sealing point, which can dry out in the event of a machine shutdown and lead to the consequences described above when the machine is subsequently restarted.
  • the invention is based on the object of developing the generic sealing device in such a way that improved restart behavior is achieved.
  • the invention is also based on the object of specifying a method for operating such a sealing device, which avoids the formation of defective packaging when restarting after a machine shutdown.
  • the moistening unit has a moistening roller and a spray device for the water-containing liquid, the moistening unit being switchable between a first operating state and a second operating state.
  • the moistening roller acts on the cover film web at a roller moistening point.
  • the spray device in the feed area acts on a spray section of the cover film web located between the roller moistening point and the sealing point.
  • the cover film web in the first operating state, is wetted with the water-containing liquid by means of the moistening roller in the feed area at the roller moistening point, guided to the base film running horizontally on the flatbed machine and vertically pressed and sealed with it at the sealing point by means of the pressing device.
  • the sealing device is put into a second operating state.
  • the spray section of the cover film web located in the feed area between the roller moistening point and the sealing point is wetted with the water-containing liquid by means of the spray device.
  • the sealing device is then returned to the first operating state and wetting is resumed using the moistening roller.
  • the cover film web is guided with its wetted spray section to the base film running horizontally on the flatbed machine and is vertically pressed and sealed with this at the sealing point using the pressing device along the spray section.
  • the basic idea is therefore to use the moistening roller known and proven from drum machines in normal operation in a flatbed machine and to accept the comparatively large distance between the roller moistening point and the sealing point. This ensures reliable and uniform moistening of the upper cover film web in normal operation using simple means.
  • the problems described at the beginning when the machine is temporarily stopped and when the machine is subsequently restarted are solved by using the spray device. When restarting and shortly before the transition to normal operation, the dried film area is at least approximately completely moistened again and thus brought into a sealable state. This renewed moistening takes place in the feed area, in which the cover film web is fed to the pressing device from top to bottom.
  • the spray section extends at least approximately from the roller moistening point to the sealing point. This ensures that the dried film section can be completely moistened again with moisture and can therefore be sealed properly without any gaps in the moistening and thus gaps in the sealing quality.
  • the spray device has a spray nozzle for dispensing the water-containing liquid in a jet fan and is designed to cover the entire spray section by means of the jet fan.
  • the width of the spray fan ensures that re-moistening of the entire spray section is completed in just a single operation. The short time required for this contributes to the homogeneity of the moisture state achieved, to a rapid resumption of normal operation and to a seamless transition of the re-moistened film section to the normally moistened cover film web.
  • the spraying device comprises an individual spray nozzle mounted on a carriage, which can be moved transversely to the cover film web by means of the carriage is. In conjunction with uniform water delivery, this allows uniform wetting to be achieved with minimal effort.
  • a nozzle with intermittent piezo delivery can be provided to generate a pulsating spray grid.
  • the spray nozzle can preferably be acted upon by the water-containing liquid from a pressure source and is designed for the continuous delivery of the water-containing liquid. In this way, a homogeneous water film can be created using commercially available and inexpensive assemblies.
  • the feed area is designed to, in the second operating state, feed the cover film web at least along the larger part of the spray section at an angle of 70° to 110° and in particular at an angle of 80° to 100° to the horizontal, i.e. at least approximately vertically lead.
  • the plane of the cover film web in its spray section is therefore at least approximately orthogonal to the plane of the horizontally guided base film web.
  • the spray direction is, on the one hand, approximately perpendicular to the spray section, which ensures effective wetting, and, on the other hand, approximately parallel to the base film, which means that it experiences practically no unintentional moistening.
  • the pressing device is positioned at the sealing point in the first operating state and away from it in the second operating state.
  • the sealing device has a stretching device which acts on the cover film web in the spray section in the second operating state. After the pressing device has been removed, it is possible by means of the stretching device to bring the cover film web starting from the sealing point completely into the upright position and to keep it stretched there in a flat state. This enables an exact Re-moistening right up to the sealing point without affecting the lower base film web. As a result, the sealing process can continue seamlessly.
  • the moistening roller is preferably lifted off the cover film web. This helps ensure that re-moistening can be carried out directly up to the roller moistening point without the moistening roller being in the way. After reapplying the moistening roller, a seamlessly moistened film surface is created.
  • Fig. 1 shows a side view of a section of a flatbed packaging machine for producing packaging units from a deep-drawn base film web 1 and a cover film web 2 sealed onto the base film web 1.
  • the packaging units are filled with dishwashing liquid, detergent or the like.
  • the packaging machine has several processing stations, but is in Fig. 1 For the sake of simplicity, only a section is shown in the area of its sealing station with the sealing device according to the invention. This is preceded by a deep-drawing station (not shown) and a filling station. The sealing device shown is followed by a separating station and a removal station.
  • a cover film web 2 is then applied and sealed to the base film web in the sealing station shown here using the sealing device according to the invention, as a result of which a multi-layer web with individual filled, tightly closed film cavities is created. These are cut out as packaging units in the separating station already mentioned and finally removed from the format plates 18 in the removal station for further use.
  • the sealing device according to the invention has a moistening unit 4 for wetting the cover film web 2 with the water-containing liquid 3.
  • Water is added here as a water-containing liquid Surfactants provided. But tap water can also be useful.
  • the moistening unit 4 includes a moistening roller 8 and a spray device 10, both of which are designed and provided for applying the water-containing liquid 3 to the cover film web 2.
  • the sealing device according to the invention further has a pressing device 5, which is designed and provided for vertical pressing and sealing of the cover film web 2 moistened by means of the moistening unit 4 with the base film web 1 at a sealing point 6.
  • the pressing device 5 is designed as a laminating roller, which rests in a line at the sealing point 6 on the format plates with the package of base and cover film webs 1, 2 in between with vertical pressure.
  • printing stamps or the like can also be used.
  • the cover film web 2 which was previously moistened and thus dissolved on its surface, is sealed onto the base film web 1 in a materially bonded manner.
  • the sealing device has a feed area 7 in which the cover film web 2 is fed from top to bottom to the pressing device 5, i.e. essentially transversely to the conveying direction 17 of the format plates 18 with the base film web 1.
  • the humidification unit 4 acts on the cover film web 2 in this feed area 7.
  • the moistening of the cover film web 2 takes place in the feed area 7, i.e. where the cover film web 2 is moved from top to bottom.
  • a stretching device 16 holds the cover film web 2 in position within the feed area 7 and in the stretched state under longitudinal tension.
  • Fig. 1 shows the sealing device according to the invention in a first operating state in which a normal, continuous sealing process is carried out.
  • the spray device 10 is passive. Rather, the moistening is carried out solely by means of the moistening roller 8, which is designed here as a felt roller and rests on the surface of the cover film web 2 in the feed area 7 at a roller moistening point 9.
  • the roller moistening point 9 can be linear.
  • the cover film web 2 lies above a small wrap angle on the moistening roller 8, so that the roller moistening point 9 has the shape of a narrow but flat strip.
  • the moistening roller 8 partially projects from above into a water bowl 19 filled with the liquid 3.
  • the moistening roller 8 absorbs the liquid 3 and releases it at the roller moistening point 9 onto the cover film web 2, distributed over its entire width.
  • the moistening roller 8 may be sufficient for the moistening roller 8 to simply roll on the surface of the cover film web 2 without its own drive.
  • the moistening roller 8 preferably has its own drive, by means of which it rotates in the opposite direction to the withdrawal direction of the cover film web 2.
  • the cover film web 2 moistened in this way is now continuously removed in normal operation, fed to the pressing device 5 and sealed as described above.
  • the sealing device is switched to a second operating state according to the operating method according to the invention, which in Fig. 2 is shown.
  • the switchover can take place while the machine is at a standstill or immediately afterwards when the packaging machine is restarted.
  • the sealing device is thus placed in a state in which the moistening roller is initially passive when the machine is restarted and in which the spray device already mentioned is used instead.
  • the spray device 10 acts on one in the feed area 7 spray section 11 of the cover film web 2 lying between the roller moistening point 9 and the sealing point 6.
  • the pressing device 5 is positioned at the sealing point 6 in the first operating state and away from it in the second operating state.
  • the laminating roller starting from the operating position of the first operating state ( Fig. 1 ) moved or pivoted to the top right, whereby the sealing point 6 is no longer covered in the second operating state, but is released upwards.
  • the stretching device 16 now holds the cover film web 2 in position and under longitudinal tension in the entire feed area 7, and in particular in a spray section 11 described in more detail below.
  • “held in position” here means that in the second operating state the cover film web 2 is guided at least along the larger part of the spray section 11 at an angle ⁇ of 70° to 110° and preferably of 80° to 100° to the horizontal.
  • the stretching device 16 is relative to the operating position Fig. 1 move to the right so far that it is positioned exactly above the sealing point 6 and thereby guides and holds the cover film web 2 in the feed area 7, namely in the spray section 11, at an angle ( ⁇ ) of approximately 90 ° to the horizontal.
  • the repositioning of the pressing device 5 and the stretching device 16 also causes a repositioning of the cover film web 2 in the feed area 7 to the right, i.e.
  • the moistening roller is still in the second operating state Fig. 2 compared to the first, normal operating state Fig. 1 including its water bowl 19 raised to such an extent that the section of the Cover film web 2 between the previous roller moistening point 9 and the sealing point 6 is exposed in the horizontal direction towards the spray device 10.
  • the spray section 11 extends as shown Fig. 2 at least approximately, here even completely from the roller moistening point 9 to the sealing point 6.
  • the spray device 10 has a spray nozzle 13 for dispensing the water-containing liquid 3 in a jet fan 12.
  • the opening angle of the jet fan 12 and the distance of the spray nozzle 13 to the cover film web 2 are coordinated with one another in such a way that the spray section 11 is completely covered by the jet fan 12 in relation to the longitudinal direction of the second film web 2.
  • spray nozzles can be arranged next to each other. This would open up the possibility of moistening the spray section 11 along the entire width of the cover film web 2 with a single spray blast using overlapping, cone-shaped jet fans 12.
  • a single spray nozzle 13 is provided, which is shown in the front view Fig. 3 is presented in additional detail. Accordingly, the spray nozzle 13 is mounted together with an associated control unit 22 on a carriage 14 and by means of this carriage 14 on a guide rail 20 according to a double arrow 21 transversely The cover film web 2 can be moved in the longitudinal direction.
  • the control unit 22 includes a needle valve, not shown, and is responsible for setting and maintaining a specific flow rate of the water-containing liquid 3 through the spray nozzle 13.
  • a pressure source 15 is provided for the water-containing liquid 3, from which the spray nozzle 13 is acted upon and fed with the water-containing liquid 3 through the control unit 22.
