Definitions

  • the invention relates to a device for loading and / or degassing of containers to be sealed with a film, in which in particular food or the like are housed, with an acting on the outer surface of the film and this airtight sealing with the edge region of the container sealing plate and to a method for loading and / or degassing of containers.
  • such devices are used to create a vacuum in containers and consist of a lifting cylinder, which transfers the containers into a space which is hermetically sealed to the outside. After the containers are introduced individually or in a certain number in this room, the room is evacuated, so the air contained in it is completely sucked off. Subsequently, the container under negative pressure with a film, which acts on the sealing plate, hermetically sealed. As soon as the film protruding from the container is separated by a cutting device, the lifting cylinder moves back onto the conveyor belt transporting the containers and these are moved on. The next batch of containers then passes onto the lifting cylinder and the evacuation process is repeated.
  • an evacuation room is provided, which increases the total investment costs, because such spaces are airtight complete to ensure their functionality.
  • the containers are to be lifted off the assembly line and transferred to a separate space to be hermetically sealed. Even such transport measures increase the cost of equipment considerably.
  • the interior space formed by the film and the container can be evacuated by means of a snorkel, it is advantageously possible to dispense with a space which is hermetically sealed off from the outside in order to produce the negative pressure in the containers. Rather, the air can be sucked into the interior of the container through the snorkel and the film serves as a limitation for the Volume content of the container.
  • the total space to be evacuated is much smaller than in the known prior art. This means that such a smaller volume than in the prior art can be evacuated very quickly or filled with the stored food preserving gas, whereby the cycle times for evacuation and for filling the container are significantly increased over the prior art and at the same time decreases the necessary gas consumption.
  • the evacuation or the gassing process is optimized so that even during the sealing of the container with the film, the interior of the container is degassed or filled with gas. Once the snorkel is then pulled out between the film and the edge region of the container, this not yet sealed area is sealed airtight by the seal stamp, so that the film is now fully sealed airtight at the edge region of the container and therefore the sealing or the Degassing process is complete.
  • FIG. 1 shows a device in the initial state for loading and / or degassing of containers to be sealed with a film, in which a foodstuff is arranged, with a sealing plate, a sealing stamp and a snorkel which projects into the interior of the container and with a valve, FIG. in which the snorkel is insertable, in front view,

  • FIG. 1 shows a device 1 for loading and / or degassing of a container 2, the edge region 3 is to be welded airtight by a film 4.
  • the interior, which is therefore bounded by the container 2 and the film 4, should be hermetically sealed after evacuation or gassing and thus reliably protect a food 5 stored therein from bacteria, fungi and other foreign bodies.
  • each mold plate 6 receives one of the containers 2, which are thus arranged in an assembly line.
  • the food 5 is already used inside the Behaiters 2.
  • the mold plate 6 is now supplied together with the container 2 a sealing station, which consists essentially of a sealing plate 7 and a feed device 8 for vertical movement of the sealing plate 7.
  • the sealing plate 7 is thus moved perpendicularly in the direction of the open side of the container 2.
  • FIG. 1 and 4 it can be seen that between the container 2 and the sealing plate 7, a clamping device 17 is provided, which consists of deflection rollers 18, between which the film 4 held under bias and parallel to the open side of the container 2 and aligned is.
  • the sealing of a partial section of the edge region 3 of the container 2 is represented by the sealing plate 7.
  • the sealing plate 7 is therefore moved in the direction of the container 2 and is about 90 to 95% on the edge region 3 and thus pushes the film 4 on this.
  • the sealing plate 7 has a the edge portion 3 of the container 2 associated recess 14, through which a clearance between the edge 3 of the container 2 and the sealing plate 7 is formed.
  • the snorkel 11 is connected to a suction device 12 and a gassing device 13, so that either the interior of the container 2 and the film 4 is closed, can be evacuated or gassed, for example with a the food preserving gas.
  • the foil 4 acts as a partition wall between the surroundings and the interior of the container 2. Furthermore, the sealing takes place through the sealing plate 7 and Degassing or fumigation through the snorkel 11 almost simultaneously, whereby a temporal optimization of the gasification or degassing and sealing is guaranteed.
  • the sealing plate 7 is returned to its starting position according to FIG. 3, at the same time a sealing stamp 15, which is arranged laterally next to the sealing plate 7, is pressed onto the edge region 3 the snorkel 11 is used so far, so that the film 4, which is not yet welded to the edge region 3, is now vulcanized by the sealing die 15 on the edge region 3 of the container 2. Consequently, after completion of this operation, the entire edge portion 3 of the container 2 is airtightly connected to the film 4 and arranged inside the container 2 food 5 is separated airtight from the outside environment.
  • the recess 14 of the sealing plate 7 is formed such that its inner contour is adapted to the outer contour of the snorkel 11. It can be provided that the snorkel 11 has a sealing ring in the region of the recess 14, by means of which an additional sealing takes place. Usually, however, the film 4 will thus nestle between the outer contour of the snorkel 11 and the inner contour of the recess 14, thereby ensuring an airtight seal in the region of the recess 14 and the snorkel 11.
  • the film 4 is first pressed by this onto the not yet sealed edge region 3 of the container 2, so that within this short period no or only very small proportions of air particles can flow through this opening into the interior of the container 2 , Immediately after the snorkel 11 off In this area has been moved out, the seal stamp 15 is delivered and pressed.
  • the cutting blade 9 is moved in the direction of the film 4, so that it is separated laterally adjacent to the edge region 3. Since the film web is dimensioned larger than the surface of the container 2, remain next to the container 2 film sections exist, is ensured by the fact that the film 4 can be moved by one cycle to airtight to seal the subsequent container 2 to be sealed.
  • FIG. 1 can also be seen that in a partial region of the wall of the container 2, a valve 21 can be inserted into which the snorkel 11 can be inserted and thus communicates with the interior of the container 2.
  • the interior of the container 2 can also be evacuated and / or gassed by the valve 21.
  • a funnel 22 is provided on its outer periphery, by means of which the delivery of the snorkel 11 into the center of the valve 21 is controlled.
  • the valve 21 is therefore opened by the snorkel 11 and once it has been pulled out of the valve 21, again hermetically sealed.
  • the interior of the container 2 is evacuated by the inserted into the valve 21 snorkel 11.
  • the snorkel 11 may be formed as a tube, as a semi-elliptical beak piece or as an insert with a flat rectangular cross-section to ensure that the film 4 rests against the outer contour of the snorkel 11 and thus reliable fumigation and / or evacuation of the interior of the container. 2 is vorappelbar.
  • the film 4 may also be formed as a metal stamped board, which is placed piecewise on the container 2 before the seal.
