Definitions

  • the generic packaging machine is from the prior art, for example DE2421531A1 , known. Increasingly high quality requirements are being placed on such packaging machines these days. At the same time, the respective packaging has to be produced more and more cheaply.
  • the present invention relates to a packaging machine.
  • This packaging machine is preferably a so-called FFS packaging machine, i. H. a so-called form-fill-seal packaging machine.
  • a web of material is transported in cycles along the packaging machine. With each cycle, a format consisting of several packaging cavities is formed into a web of material, usually a web of plastic film, for example by deep-drawing, and after the respective packaging cavity has been filled with a packaged good, they are sealed in a sealing station with an upper web of material, which is in usually also is a plastic film web, closed. The upper web of material is connected to the lower web of material in particular by sealing.
  • the packaging trays are now degassed and gassed according to the invention, with a certain vacuum, d. H. a certain negative pressure is generated in the packaging cavity. During gassing, gas exchange takes place in the packaging cavity, i. H.
  • the atmosphere of the packaging tray is at least partially replaced by a replacement gas.
  • This gas exchange can follow a degassing of the packaging tray.
  • the replacement gas can be, for example, nitrogen, carbon dioxide, argon or oxygen or a mixture of these or other gases.
  • the packaging machine has a gassing and degassing means with which the individual packaging cavities of a format can be gassed and degassed individually. It is preferably possible to gas and degas all packaging cavities differently. This makes it possible to individually take account of the conditions prevailing in the respective packaging tray. Consequently, the degassing and/or gassing time can be shortened, as can the volume that is removed from the packaging tray during degassing or blown into the packaging tray during gassing becomes, can be reduced. As a result, the respective packaging can be produced more cheaply and/or faster and/or with higher quality. Furthermore, the negative pressure generated in the respective packaging trough or the amount of gas supplied to the respective packaging trough can be recorded and precisely logged, which can be of great importance in quality monitoring.
  • the gassing and degassing means are provided as a unit.
  • Such a format has at least one column, one column having a plurality of packaging troughs arranged transversely to the direction of transport of the lower material web.
  • Such a format preferably has a plurality of such columns, which are arranged one behind the other in relation to the transport direction of the lower material web.
  • a format also has several rows of packaging troughs, which are arranged parallel to the transport direction of the lower web.
  • shut-off element for example a valve
  • this shut-off element it is possible, for example, to individually determine the volume of gas that is removed from the packaging trough or blown into the packaging trough.
  • the packaging machine has a measuring device, preferably one measuring device per packaging cavity, one measuring device per row and/or one measuring device per column of a format with which the pressure and/or the concentration of at least one gas component in the /the packaging cavities can be determined.
  • the packaging machine according to the invention is provided with a control that controls, for example, the shut-off element.
  • this regulation takes place on the basis of one or more signals from the measuring device.
  • the packaging machine has a means with which the filling level of the packaged goods in the respective packaging trough and/or the filling quantity of the packaged goods within the respective packaging trough can be determined.
  • the shut-off device will then be regulated as a function of this measurement signal, to individually regulate the gas volume that is taken from or supplied to the respective packaging tray.
  • the gassing and degassing means is preferably a replacement part that is replaced when the format is changed. With this preferred embodiment of the present invention, it is also possible to exchange the gassing and degassing means when there is a format change, so that a gassing and degassing means adapted to the respective format can be used.
  • the gassing or degassing means is preferably provided by means of a quick-release fastener on the packaging machine according to the invention.
  • FIG 1 shows the packaging machine 1 according to the invention, which has a deep-drawing station 2 , a filling station 7 and a sealing station 19 .
  • a web of material 8 here a web of plastic film 8, the so-called lower web, is pulled off a supply roll and transported intermittently along the packaging machine according to the invention from right to left. In one cycle, the material web 8 is transported further by one format length.
  • the packaging machine has two transport means, in the present case two endless chains each, which are arranged to the right and left of the film web. At least one gear wheel is provided for each chain both at the beginning and at the end of the packaging machine, around which the respective chain is deflected. At least one of these gears is driven.
  • the gear wheels in the input area and/or in the output area can be connected to one another, preferably by a rigid shaft.
  • Each transport means has a large number of clamping means which clamp the web 8 in the infeed area 26 and transmit the movement of the transport means to the lower film 8 .
  • the clamping connection between the means of transport and the web 8 is released again.
  • the packaging troughs 6 are formed into the film web 8.
  • the lower tool 4 is arranged on a lifting table 5 which, as symbolized by the double arrow, can be adjusted vertically. Before each film feed, the lower tool 4 is lowered and then raised again.
  • the packaging cavities are then filled with the packaged goods 16 in the filling station 7 .
  • the subsequent sealing station 19 which also consists of an upper tool 12 and a vertically adjustable lower tool 11, an upper film 14 is materially attached to the web 8, preferably by sealing.
  • the upper tool and/or the lower tool are lowered or raised before and after each film transport.
  • a certain negative pressure is generated in the filled packaging tray and/or a gas exchange takes place. The generation of the negative pressure or the gas exchange preferably takes place while the respective packaging tray is located within the sealing station, preferably immediately before the sealing tools 11, 12 are pressed against one another.
  • the upper film 14 can also be guided in transport means or transported by transport chains, with these transport means then only extending from the sealing station and possibly downstream. Otherwise, the statements made regarding the means of transport for the lower film apply.
  • the finished packages are separated, which in the present case takes place with the cross cutter 25 and the longitudinal cutter 27 .
  • the cross cutter 25 can also be raised or lowered with a lifting device 9 .
  • FIG 2 shows the sealing station of the packaging machine according to the invention, in which a web of upper film is sealed onto the filled packaging trays 6 .
  • the packaging cavities which have not yet been sealed with a cover film are provided with the reference number 6, while the packaging cavities which have already been sealed are provided with the reference number 6'.
  • this packaging machine works in cycles, with a format 15, which in the present case consists of three rows 24 and three columns 18 of packaging trays, being transported further by a certain amount, in particular by the length of the format 15, with each cycle .
  • the transport direction is symbolized by an arrow.
  • air is sucked out of the packaging cavities before the respective packaging cavities are closed with the cover film.
  • this degassing means 17 is designed in such a way that the volume of gas that is removed from the respective packaging tray can be regulated individually.
  • the packaging machine according to the invention has a gassing means 13 which can be constructed identically or similarly to the degassing means 17 .
  • the gassing agent too, it is possible to set the gas quantity supplied to the respective packaging tray and/or the gas composition supplied to the respective packaging tray individually.
