Definitions

  • the invention relates to a method for automated filling of a bag according to the preamble of claim 1 and a filling device according to the preamble of claim. 7
  • stand-up bags In practice, filling devices for bags, in particular stand-up bags, have proven themselves.
  • stand-up pouches or carry-bags are popular because of their environmentally friendly lightweight packaging. Moreover, these can be recloseable via special valves or twist-off closures located on a neck of the bag, and are also efficient and easy to handle from a logistical point of view.
  • Such stand-up pouches are therefore preferably used for liquid, pasty or else for lumpy foods or hygiene articles.
  • the stand-up pouches are typically fed into containers of the filling device and then guided by a conveyor to a filling station, filled and then closed by means of a lid or a cap. Subsequently, the sterilization is usually carried out by a thermal pasteurization or thermal sterilization and packaging in containers.
  • the filling station is arranged in a sterilized room, which is kept permanently sterile, that in the sterile room one or more arms are arranged, remove the attached to the respective bag lid before filling or unscrew and after filling again Apply to the bag, a fully automated method for filling the bag is provided, which can be accomplished without expensive sterilization and manual operations.
  • the sterile space is separated by walls from the environment and at least one transition region, which is for example designed as a lock, door, brush seal, revolving door or the like, through which the bag or bags by the conveyor in these are on or ausbringbar.
  • the sterile space is preferably kept in a slight or slight overpressure by means of aeration, so that the sterilized air flows out of the sterile space essentially through the transition area.
  • the overpressure can be accomplished by means of a ventilation, which sucks the air from the environment and cleans or sterilizes by means of a filter or membranes.
  • a ventilation which sucks the air from the environment and cleans or sterilizes by means of a filter or membranes.
  • the pore size of the filters or membranes are sized smaller than the size ratios of germs, bacteria, viruses.
  • the driven arm removes the lid of the bag and preferably positions it so that it is conveyed together with the bag by the conveyor in the sterile room.
  • the driven arm has for this purpose a gripper, which can detect the lid and removes it by a screw or lifting movement of the opening of the bag.
  • the powered arm may further include a sensor that detects the number of revolutions, torque or force to ensure proper closure of the bag after filling.
  • the intermediate storage serves to transport the lid, so that it is moved together with the respective bag by the conveyor.
  • the intermediate storage can also be easily replaced by a bypass.
  • one or more air nozzles can be arranged.
  • An air nozzle can inflate or blow-through the bags prior to filling by means of sterile air, so that the inner sides of the bag which lie adjacent to one another on delivery are separated from one another.
  • the inner sides of the bag are namely due to adhesion forces in the delivered state to each other.
  • one or more filling stations can be arranged along the conveyor, which proportionally introduce the medium into the bag.
  • the filling station has for this purpose a filler neck, which introduces the medium into the bag through the opening of the bag.
  • the filler neck can simultaneously discharge the air displaced by the medium from the bag.
  • one or more further air nozzles or nozzles can be provided, which blow out or spray the lid and the filled bag before closing in order to possibly also remove residues of the medium.
  • the lid is received by the driven arm or its gripper and positioned in front of the air nozzle for blowing or spraying.
  • the air nozzle or the nozzle can be arranged in or on the intermediate storage or bypass in order to optimize the filling process and to increase the filling capacity of the system.
  • the nozzle may spray a disinfecting medium, for example, hydrogen peroxide-impregnated air, liquid peracetic acid or the like.
  • the air nozzle or nozzle may also be connected to the conveyor be moved and spray through a passage opening in the intermediate storage from below the lid or spray.
  • FIG. 1 is a filling device 1 for filling of individual bags 2, preferably stand-up bags or carry-bags shown.
  • the bags 2 have a bag opening 5, through which the medium 7 in the interior of the bag 2 can be filled.
  • the opening 5 of the bag 2 is formed for example as a neck with a thread 39 or a plug 40 and closed by means of a cover 6 described in more detail below.
  • the opening 5 is typically welded to the bag and can be arranged at one of the corners of the bag 2 - as a so-called corner pouch - or in the middle of the bag 2 - as a so-called center pouch.
  • the bags 2 sterile closed with the lid 2 are the filling device 1 at an insertion station 22, respectively.
  • the insertion station 22 has a placement device 25, which feeds containers 3 or isolated bags 2 to a conveyor 21.
  • the conveyor 21 conveys the bags 2 from the insertion station 22 into a sterile space 10 of the filling device 1 and brings them out after completion of the filling process by a filling station 23 from the sterile room 10 and conveys them to a removal station 24th
  • the sterile space 10 is enclosed by one or more walls 14 and held by a vent 31 continuously in an overpressure relative to the environment 8.
  • the overpressure in the sterile chamber 10 causes leakage through it to exclusively cause the sterile air 33 to flow from the sterile room 10 into the environment 8. An influx or penetration of contaminated air 9 in the sterile room 10 is thus prevented.
  • the ventilation 31 is provided with a filter system 32 which cleans or decontaminates the air 9 sucked from the environment 8 and ensures the sterility of the air 33 in the sterile room 10.
  • the conveyor 21 is designed carousel-shaped. First, the sterile closed with the lid 6 bags 2 are transferred to the carousel 21. The bags 2 are isolated by a positive or non-positive holder 14 is locked to the conveyor 21. The conveyor 21 is then rotated stepwise or clocked, so that the bags 2 are moved sequentially to perform the individual process steps in the sterile room 10.
  • FIG. 2 the schematic representation of FIG. 2 the individual process steps in the sterile chamber 10 of the filling device 1 can be seen.
  • the lid 6 of the sterile bag 2 is initially unscrewed or withdrawn by means of a mechanically driven arm 11. Subsequently, the lid 6 is positioned next to the bag 2 on the conveyor 21 or an intermediate storage 26.
  • the mechanical arm 11 has for this purpose a gripper 12 which can grasp the lid 6 and pulls it off from the opening 5 of the bag 2 by means of a screwing and lifting movement.
  • the holder 13 of the conveyor 21 forms a kind of counter bearing for the driven arm 11 so that the bag 2 is not twisted in the conveyor 21 during unscrewing or is positioned unchanged when the cover 6 is removed.
  • the bags 2 are opened by means of a jet from an air nozzle 34 with decontaminated or sterile air 33.
  • a jet from an air nozzle 34 By injecting the compressed air into the bag 2, the adhesion forces between the two superimposed inner sides 4 of the bag 2 are separated, so that the filling in the subsequent process step at a filling station 23 is trouble-free and particularly quickly feasible.
  • a filler neck 16 is inserted into the opening 5 of the bag 2, which injects the medium 7 to be filled into the bag 2 and optionally removes or sucks the air 33 displaced by the medium 2 from the bag 2.
  • the bag 2 is to be closed with the lid 6. This is done by the mechanically driven arm 11, which engages the lid 6, which was initially positioned next to the bag 2 on the conveyor 21, and this screwed onto the bag 2 and this touches.
  • the mechanical arm 11 detects the position of the lid 2 relative to the opening 5 of the bag 2 to check a proper closing of the bag 2.
  • one or more passage openings 27 can be introduced or incorporated, which make it possible for the air nozzle 34 or the nozzle 35 to blow off the cover 6 from below with sterile air 33 or a sterilization medium 41.
  • a sterilization medium for example, air 33 enriched with hydrogen peroxide, liquid peracetic acid or the like can be used.
  • the bag 2 then leaves the sterile room 10 through the transition region 15 and is supplied to the removal station 24.
  • an ejector 18 is arranged in the sterile room, which dissolves the bag 2 of the holder 13 of the conveyor 21 and transferred into the transition region 15.
  • the transition region 15 is formed in this embodiment as a vertical channel. Accordingly, the bags 2 are ejected from the holder 13 of the conveyor 21 from the sterile room 10 and leave this falling through the vertical channel.
  • the conveyor 21, for example, be designed as a chain or belt conveyor and catches the filled bag 2 and takes over the transport to the removal station 24th
  • FIG. 3 an alternative embodiment of the method for filling the bag 2 can be seen.
  • the lid 6 is initially received by the mechanical arm 11 of the conveyor 21 or the intermediate bearing 26 and held in front of one or more nozzles 34.
  • the lid 6 is then blown separately or together with the opening 5 of the bag 2 with sterile air 33 and only after this step, the bag 2 is closed with the lid 6.
  • the lid 6 and / or the opening 5 of the bag 2 can be sprayed by means of a nozzle 35 with a degermination medium 41.
  • the filling process may be divided into a plurality of filling stations 23 arranged in series along the conveyor 21, each filling station 23 proportionately filling medium with one of the filler neck 16 into the bag.
  • An alternative embodiment of the filling device 1 is the FIG. 4 to see that provides a linear guidance of the bag 2 through the sterile room 10.
  • the movement through the conveyor 21 of the bag 2 can be clocked, that is, carried out sequentially or continuously.
  • the continuous movement of the bags 2 in the sterile room 10 can be accomplished by movably mounted mechanically driven arms 11 and air nozzles 34 and filling stations 23.
  • the bags 2 can be seen in three different states, namely partially closed, opened and completely closed.
  • the openings 5 of the bags 2 are designed as plugs 40, but the one explained below is transferable.
  • the bags 2 are supplied in the partially closed state as a single bag 2 or in containers 3 through the placement device 25 of the filling station 22 of the filling device 1.
  • the lid 6 and the opening 5 of the bag 2 on a hygiene barrier 37 which is characterized in that on the one hand the bag 2 is sealed sterile and on the other hand, the cover 6 can be removed from the bag 2 nondestructive.
  • a seal 38 is typically attached to the lid 2, which is destroyed when the lid 6 is opened by the consumer.
  • the partially closed state indicates that the seal 38 is non-destructively removable from the bag 2 with the lid 6.
  • the closed state of the bag 2 is characterized in that the lid 6 is applied by the driven arm 11 to the opening 5 of the bag 2 and the bag 2 is thus sealed.
  • the seal 38 is to move over the hygiene barrier 37 whereby the seal 38 in the manner of an undercut or a door latch surrounds this.
  • a proper closure of the bag 2 can thus be accomplished by the driven arm 11 in a variety of ways.
  • the cover position, the force curve during application of the cover 6, the number of revolutions in the screwing of the lid 6 with a thread 39 or the like may be detected.
  • one or more abutment surfaces 36 may be integrally formed on the opening 5 of the container 2, through which the bag 2 rail-shaped by the conveyor 21 can be performed.
  • the contact surfaces 36 at the opening 5 of the bag 2 allow a wrench-like locking by the holder 13 can be done so that the bag 2 when screwing the lid 6 with a thread 39 does not follow the rotational movement and thus the positional loyalty of the bag 2 in the conveyor 21 is given during the transport of the bag 2.
  • the abutment surfaces 36 serve for the horizontal storage of the bag 2 on the conveyor 21.
  • FIG. 6 schematically shows the provision of the sterile bag 2.
  • they are bag 2 together with the opening 5 and the lid 6 made separately from each other and then brought together so that the partially closed state of the bag 2 is present.
  • the bags 2 are sterilized in the partially closed state and packaged in containers 3.
  • the sterilization can be carried out by means of ⁇ -rays or comparable processes and from different irradiation directions.
  • the intermediate storage 26 can be easily replaced by a bypass.
  • the driven arm 11 which removes the cover 6 from the bag 2 thus transfers the cover 6 to the bypass, which in turn conveys it to the driven arm 11 which re-applies the cover 6 to the bag 2.
  • the intermediate bearing 26 or the bypass can also be dispensed with by removing the cover 6 from a bag 2 and placing it on a bag 2 that has just been filled.
  • one or more air nozzles 34 or nozzles 35 can also be arranged, which blow or spray the lid 6 over one or more cycles.
  • the filling process of the bags 2 is accelerated since the cover 6 does not have to be pivoted in a blow-out position by the driven arm 11 in a complicated manner.
