Definitions

  • the invention relates to a packaging machine for packaging goods to be disposed of according to the first part of patent claim 1.
  • Such a packaging machine is known from DE-A-3 231 221. This has a hinged lid over the opening of the bag. On one side of the bag, a single film blank or a film web is arranged, which can be pulled over the bag opening after filling by means of pull chains, so that the inside of the bag can be closed with the film pulled over it.
  • a packaging machine is known from EP-A-0 299 821 in which individual filled containers are passed through a sealing station together with a cover film.
  • This sealing station has an upper part which is connected to a vacuum source for lifting the cover film.
  • the object of the invention is to provide a vacuum packaging machine of the type described above with a simplified structure create with which the goods to be disposed of can be easily packaged without pollution of the environment.
  • the vacuum packaging machine is designed as a so-called chamber machine. It comprises a housing 1 with a Container space 2 for receiving a bag, a lid 3 for closing the container space, an operating panel 4 and foot switches 5, 6.
  • the container space 2 is formed by a cylindrical container 7 which extends essentially vertically downward from the upper side of the housing and is closed with a bottom on its underside.
  • the opening of the container space is surrounded by a ring 8.
  • the lid 3 is connected to the housing 1 on its rear side 9 so that it can pivot about a pivot axis 10.
  • retaining bolts 11, 12 are provided on the surface facing the cover for receiving the edge of the bag.
  • Retaining bolts 13 are also arranged in the cover on the side opposite the pivot axis 10, that is to say on the opening side.
  • the cover 3 has on its two sides extending transversely to the pivot axis 10 and parallel to the side edges 14, 15 of the upper side of the housing 1 extending side walls 16, 17. These are shaped in such a way that, in the manner best seen in FIGS. 1 and 2, they laterally limit or seal the space between the top of the container space and the inside of the cover when the lid is open.
  • the inside of the cover has a suction opening 19 which extends across the entire opening. This is connected via a hose 20 to a vacuum pump 21, which in turn is connected on the output side via a hose 22 to a filter 23, the output side of which leads back into the interior of the housing. Housing and associated lid are sealed so that when the lid is closed, the inside of the container is hermetically sealed from the outside.
  • a pneumatically operated stamping device 25 designed as a piston-cylinder device is provided on the bottom side of the container space 2.
  • the cylinder is fixed in the housing. Its stamp, which extends into the container space 2 on the bottom side, has a plate 26 on the front side which extends essentially perpendicular to the direction of the axis of the cylindrical container space 2.
  • the piston-cylinder device is designed in such a way that the plate can be moved from the retracted position shown in FIG. 2 into the advanced position indicated by dashed lines.
  • the lid is held in the closed position by the negative pressure generated inside the container.
  • a locking device (not shown) can also be provided, which locks it in the hermetically closed position.
  • the opening of the cover is pivoted upward by an opening angle ⁇ of approximately 30 degrees to the lower part by releasing the negative pressure or releasing the locking device by a device not shown in the filling position shown in FIG. 2.
  • Large parts can also be placed in the waste bag via the opening width that is released as a result.
  • the lid with the device not shown is pivoted up to an angle ⁇ of about 65 degrees relative to the lower part, so that the package containing the waste product can be easily removed.
  • the preferred embodiment of the bag 27 used with the machine is shown in FIG. 8.
  • the actual bag part 28 has a round edge and a rectangular collar 29 welded to it. This is a Rectangular film cut with a circular opening 30.
  • the collar 29 is fixedly connected to a cover part 43 via a fold 31 or is formed integrally therewith.
  • the cover part 43 can be folded onto the opening and welded to the collar.
  • the collar has two holes 32, 33 arranged opposite one another on the edge side adjoining the fold 31 and corresponding holes 34, 35 on the free side opposite the fold.
  • the cover part 43 itself has corresponding holes 36, 37 on its free edge side opposite the fold edge.
  • the holes 32 to 35 are arranged geometrically according to the position of the retaining bolts 11-13.
  • the retaining bolts 11-13 are guided in associated bolt guides 38-40.
  • the bolts 11, 12 guided in the ring 8 are firmly attached to the housing.
  • the bolts 13 guided in the part 55 forming the inner surface of the cover are prestressed with the aid of compression springs 41 each lying in a blind hole on the base in the position shown in FIG. 6 projecting beyond the inner surface of the cover.
  • the head of the bolts is conically turned outward in the manner best seen in FIG. 7 and has a backward rotation 42.
  • the waste bag shown in FIG. 8 is inserted with its bag part 28 into the container space 2, and the collar and the cover part are hung with their holes 32-37 into the associated bolts, as best shown in FIGS. 2, 3 and 6 can be seen. It is thereby achieved that the bag is held firmly in its position both in the closed state and in the open state, and in particular the cover part 43 of the bag always lies against the inside of the cover opposite the opening 30 of the bag part and prevents this inside from being soiled.
  • the sealing device used to weld the parts of the bag part 28 or collar 29 and cover part 43 which are not connected to one another can be seen in particular from FIGS. 4 and 5.
  • a groove 45 is provided in the surface 44 facing the inside of the cover, the contour of which corresponds to the desired sealing seam, as can be seen from FIG. 5.
  • a heater 46 designed as a tubular heating element is provided in this groove.
  • the resistance element 47 is insulated in a thin metal tube 48 with a total thickness of approximately 4 mm.
  • the tubular heating element is held in the groove by conical disks and can expand both radially and axially when heated. There is therefore no need for a clamping device, as is usually used for welding with pulse bands.
  • tubular membranes 49-51 on the underside of the ring, which can be actuated via a compressed air source 52 in such a way that the ring 8 in the direction of arrow 53 from the one in FIGS. 3, 4 and 6 shown lowered position is raised to the sealing position shown in Fig. 7.
  • an abutment 54 made of an elastomer is provided on the inside of the cover.
  • the tubular heater 46 and the abutment 54 act together for welding the collar 29 and the cover part 43 of the bag.
  • the heads of the retaining bolts 13 are pressed back into the bolt guides in the manner shown in FIG. 7.
  • the ring 8 simultaneously slides over the bolts 11, 12 so that they are in the bolt guides disappear. This will push the collar off the bolts.
  • the controller 24 is connected on the one hand to the control panel 4 and the foot switches 5, 6 and on the other hand to the vacuum pump 21, the device releasing the open position of the cover, the sealing device, the stamping device and optionally the locking device.
  • the open position of the bags shown in FIG. 1 is first used in such a way that the connecting edge of the collar and cover part extends essentially parallel to the rear pivot axis 10, as can best be seen from FIG. 2.
  • Holes 32 - 37 are hooked into the retaining bolts.
  • the control is designed so that when the chamber lid is closed, the interior in the housing and container space, and thus in particular inside the bag, is evacuated to a predetermined value of preferably about 700 mbar.
  • the evacuation by means of the vacuum pump 21 prevents gases from escaping from the goods to be packaged.
  • the specified negative pressure is maintained when the lid is closed by appropriate control and restored after each intermediate filling.
  • the locking of the lid 3 is released by actuating the foot switch 5.
  • the suction at the suction opening 19 is switched on, so that the air is sucked off above the opened bag. This ensures that the operator does not come into contact with contaminated suspended particles and gases when the lid is open and nothing is released into the environment.
  • the lid closes automatically as soon as the foot switch 5 is released.
  • the atmosphere in the chamber and bag interior is then evacuated to the specified value as described above.
  • the evacuation is first continued to a predetermined target value so that the desired vacuum prevails inside the bag.
  • the ring 8 is lifted over the tube membranes 49-51, and the sealing device 46-48 seals it.
  • the interior of the chamber is first vented.
  • the stamping device 25 is controlled in such a way that the bag is compressed via the plate 26 before or during the ventilation process in order to reduce its volume and to achieve a desired compact shape.
  • the lid can then be opened.
  • the lid is opened - in this case with the vacuum pump switched off - and the finished sealed package can be removed and replaced with a new bag to be hung in.
