Definitions

  • the invention relates to a method and a device for protective gas purging of containers, in particular for Food, according to the preamble of claim 1 and the Claim 7.
  • Containers can in a known manner in a vacuum chamber evacuated and then with a protective gas, for example nitrogen.
  • a protective gas for example nitrogen.
  • DE 42 24 919 A1 and DE 42 24 920 A1 are also Process for oxygen-free packaging in one multi-compartment menu tray with a flat cover known in which the air inside the container is flushed out with a protective gas.
  • the protective gas occurs e.g. between the compartments of the menu tray perpendicular to the Cover is made by and at a short distance to Menu tray cover held parallel to the filling opening distracted.
  • the protective gas flows between the Cover and the menu tray radially in all directions outside against the edge of the filling opening.
  • a Sealing device sealed gastight For the most common container types, such as. B. cans, this is Procedure not applicable.
  • the invention is therefore based on the object, defects of To fix the state of the art. So a procedure and a device can be proposed with its Use a protective gas purge of various types Types of containers, such as cans, is made possible. moreover this is compared to the evacuation and subsequent Gassing with a protective gas with a much lower one time can be done. Last but not least one Inert gas purging of containers can be proposed several stations, in particular arranged in a ring is assigned to a processing station for containers.
  • a container When in connection with the invention of a container is a container be at least a rigid or semi-rigid wall having.
  • cans are to be understood by this be an essentially tubular wall exhibit. This wall is gas-tight at one end completed and at the other end via a closure element to be sealed gas-tight.
  • protective gas flows into one Walls limited channel and on the other hand from this out again.
  • the container with its Filling opening through a wall delimiting the channel to the flowing shielding gas in such a way that in the edge area the protective gas essentially parallel to the filling opening The area of the filling opening flows in and out in a directed manner.
  • the protective gas Depending on the speed and amount of flowing protective gas and the duration of the protective gas purging gas is displaced from the can by the protective gas. Thereby a given residual oxygen or Residual water vapor content in the tank reached or be undercut.
  • a device for recording the Oxygen content for example in the interior of the Container, provided, can via a feedback with the actuators that control the flow of inert gas, the specified value for the residual oxygen content self-regulating can be set.
  • the wall of the channel opposite the filling opening can be designed so that at least part of the Shielding gas, advantageously essentially in one Direction in the channel flows over the filling opening.
  • the inflowing and the outflowing protective gas also have Advantage overpressure or underpressure over the Environment. This way the speed of the flowing shielding gas without significant pressure increase in the Containers can be increased.
  • a device has several walls on that limit a channel. Flows into this channel protective gas on one end and off again on the other.
  • a the Flow-limiting wall of the channel has an opening to which a container is brought with its filling opening is.
  • the channel points for the inlet and outlet openings for the Shielding gas in the edge area of the filling opening. It flows the protective gas parallel to the surface of the filling opening the edge area on and off.
  • the one directed through the chamber Shielding gas flowing in and out comes through the filling opening in contact with gas inside the container. Thereby is gas from the interior of the container by protective gas replaced.
  • Form the channel and the interior of the container a purging chamber in which the protective gas purging takes place.
  • An embodiment of the invention essentially sees one gap-shaped, horizontally arranged channel for the one and outflowing shielding gas.
  • the channel is through a upper and lower wall bounded.
  • a washable Container is attached to the through a recess in the lower wall flowing shielding gas can be brought up.
  • the container is perpendicular to the flow direction of the Shielding gas through the recess in the wall to the Shielding gas flow introduced.
  • Such a device for Inert gas flushing can be made relatively flat and as a result also on existing processing stations for containers be installed.
  • the inert gas flow is introduced Containers over the outside of their tubular wall connected to the bottom wall. This will keep them Inside of the tubular wall and the front with the filling opening for any machining processes accessible.
  • the tightness of the connection can be determined by a Sealing lip can be guaranteed, the circumferential on the tubular outside.
  • a further development of the invention provides for several Stations that process containers in the same cycle, one Assign device for protective gas purging, which over spans several stations. This can, for example rinsed out a can at a protective gas flushing station and to another station under a protective gas atmosphere, for example a capping station, without ambient air getting into the can. Can too with its distributed over several stations Inert gas purging the purging process to several Stations, possibly also on the conveyor line between these stations. The result achievable advantages are obvious.
  • stations arranged in a ring can pass through a channel for the flowing protective gas, the for example, the lower wall is movable and the upper wall is stationary, simple and reliable Way with a device for protective gas purging become.
  • Another embodiment of the invention sees - for example designed in the form of two perforated disks - a movable one lower wall and a movable upper wall in front.
  • the two Perforated disks are placed against the center, wedge-shaped spacers kept spaced from each other and together with the spacers essentially form the channel guiding the inert gas flow.
  • Figure 1 shows a processing station for as cans trained container, at which no closer to several shown stations processed cans in the same cycle become.
  • the processing station has a table top 1, the stations and one designed as a rotary star 4 Funding an embodiment of a device for protective gas purging 5 according to the invention, which flushes out cans with protective gas at three stations.
  • the device for protective gas purging 5 shows here Upper housing 7 a perforated disc 8 rotatable about the axis of rotation 3 and a dashed line that is not visible in FIG. 1 drawn lifting device.
  • Lifting device has a lifting ramp 13 and at one end at the other end a descent ramp 14 for lifting one sealing can or for lowering one with a Closure element 22 provided can.
  • the two ramps 13 and 14 are - based on the direction of rotation of the rotary star 4 - arranged in the area before or after the upper part 7 and over a curved rod that is rectangular Cross-section connected.
  • the perforated disc 8 here has the shape of an annular disc, in which eight regularly arranged recesses 10 are provided. In each of the recesses 10 is in each case a box can be inserted.
  • the perforated disc 8 is above that Rotary star 4 coaxial to this in one by the height of the Cans predetermined distance from the table top 1 arranged.
  • Figure 1 covers the perforated disc 8, the outer contour of the Rotary star 4, which is shown in dashed lines.
  • the Rotary star 4 and the perforated disc 8 lead around the axis of rotation 3 the same rotary movements.
  • Cans when transported from one station to the next the lifting ramp 12 or the Absenkrampe 13 pass, are in the recesses 10 pushed in or out. This movement of the Can relative to the perforated disc 8 is perpendicular to Direction of delivery directed.
  • the cans are made by the Rotary star 4 and the guardrail 6 out.
