Definitions

  • the present invention concerns a method for packing articles, liquid or loose material in film bags which are conveyed through a filling station in a continuous web of bag items, wherein the bag openings are kept open for reception of articles after which the bags are closed and separated from the web, by which method the bag web initially and along its opening edges is brought into guiding connection with guide means adapted for retaining and guiding peripheral areas at the opposing bag opening edges along a conveyor path through the filling station, as in connection with this passage the guide means force the bag opening edges apart for successive opening of the bags in the filling station, and then, after filling the bags, joining the bag opening edges for closing the bags, by which method the opposing bag opening edges are mutually unfolded and by which method the bag web is brought to engage the guide means by being conveyed on a support rail, the guide means ensuring retention of the bag web along the conveyor path through the filling station.
  • the invention furthermore concerns an apparatus for performing such a method, including:
  • the invention further concerns a bag web for use by such a method and in such an apparatus, the bag web including a contiguous series of bag items separated by a number of slits extending from a bottom edge of the web to a point below a upper edge of the web, the lateral edges of the webs being closed by welds, and where the bag web includes a central support region extending longitudinally of the bag web, the support region connecting bag items that are disposed side by side transversely of the web.
  • EP-696997 A basic example of this technology is mentioned in EP-696997 in which it is stated that the opposite upper edge areas of the bag item web is made with bent peripheral parts formed by grooves for drawing in on conveyance bars which have a mutual expansion for producing an opening of the bag items in the direction of conveyance, such that these can be filled, for example through a superjacent funnel, whereafter the conveyance bars are narrowed against each other again for temporary closing of the filled bag items. These may then be closed finally by welding below the said duct parts, after which these are cut off and the items are mutually separated.
  • the channel parts there may be used edge thickenings that may be received in slotted guide tubes for corresponding conveying of the bag items.
  • EP 1 087 890 is described a technique which uses a simplified flat bag web as said opening edge is merely closed when the web is introduced on a single carrier bar and is continuously cut open in a station whereby the thereby upright peripheral strip parts are unfolded in order to be laid down on opposite chains.
  • These strip parts are made in advance with a row of holes which are moved down onto upwardly pointed holding studs on the carrier chains during folding down whereby a safe carrier and propelling engagement is achieved without any special profiling of the opening edges.
  • EP 1 451 069 discloses a similar technique.
  • edge strip parts will also be made in advance with a row of holes which are moved down on upwardly directed holding studs on the carrier chains during folding down such that a secure carrier and propelling engagement is achieved without any special profiling of the opening edges.
  • the bag web is conveyed with a series of bag items that are positioned in longitudinal direction and filled successively.
  • a further object of the invention is to indicate a bag web of bag items enabling a high filling rate and cheap production of the bags.
  • this object is achieved by a method of the kind mentioned in the introduction, and which is peculiar in that the bag web is provided with a central support region extending longitudinally of the bag web, the central support region formed as an entirely or partially closed channel, and where the central support region connect bag items that are disposed side by side transversely of the web, the central support region being conveyed on the support rail along the conveyor path through the filling station, and that peripheral areas at the outermost opposite bag opening edges of two juxtaposed bag items are brought in guiding connection with the guide means.
  • An apparatus according to the invention is peculiar in that the support rail extends along the conveyor path through the filling station for supporting the bag web at a central support region extending longitudinally of the bag web and connecting bag items that are disposed side by side transversely of the web, as the support rail is adapted for being received in the entirely or partially closed channel in the central support region of the bag web.
  • a bag web according to the invention includes a central support region extending longitudinally of the bag web and connecting bag items that are disposed side by side transversely of the web, and which is peculiar in that the central support region is formed as an entirely or partially closed channel, and that the peripheral areas at the outermost opposite bag opening edges of two juxtaposed bag items are adapted to be brought into guiding connection with guide means.
  • This central support region is supported on the support rail which is known from the technique in the two European patents EP 1 087 890 and EP 1 451 069 . It is only necessary to extend such a support rail so as to extend along the conveyor path through the filling station for supporting the two juxtaposed bag webs in the filling station. Bag items from each of the two rows will be supported by the common central guide rail at their common central support region, and supported by the guide means at each of the peripheral areas at the outermost opposite bag opening edges of two juxtaposed bag items.
  • the central support region is formed as an entirely or partially closed channel, a more secure guiding of the bag web is achieved. Furthermore is achieved the advantage that different weights of the two juxtaposed bag items will not draw the web askew.
  • a channel at the central support region it becomes possible to fill the two juxtaposed bags with different weight. They can also be filled at different times. The requirements for positioning of filling funnels and similar filling equipment will therefore be more flexible than in a situation where simultaneous filling of two juxtaposed bags has to be performed.
  • the guide means can thus be designed according to the above described prior art techniques as well as the peripheral areas of the bag items can be designed according to the prior art techniques. There is only need for modifying the filling station in a way so that it e.g. has two filling units that fill the two juxtaposed bag items simultaneously.
  • Carrier chains or similar in the guide means can therefore be moved through a course wherein in the filling station they will draw the two outermost bag edges apart in such a way that the two juxtaposed bag items are caused to open in order to enable filling of products into the two bag items from above or possibly from the side.
  • the bag edges can then be guided together again for the purpose of final closing and cutting off of the filled bag items.
  • the guide means will typically be drawn apart such that the cut off bags can be gripped and moved away, or just fall down upon a conveyor belt.
  • the method may be peculiar in that the peripheral areas at the outermost opposite bag opening edges of two juxtaposed bag items are joined by welding or welded together with the central support region.
  • the method may be peculiar in that the peripheral areas at the outermost opposite bag opening edges of two juxtaposed bag items are joined by welding or welded together with the central support region.
  • the method may be peculiar in that the peripheral areas at the outermost opposite bag opening edges of two juxtaposed bag items are free peripheral areas. This simplifies the bag making itself, though the free peripheral areas put greater demands on guidance during conveying of the bag web through the apparatus.
  • the apparatus may be peculiar in that the support rail includes an endless band, belt or similar for supporting the bag web.
  • the bands or belts may thereby contribute to the conveying of the bag web.
  • the apparatus may be peculiar in that the filling station includes a first and a second filling unit, or alternatively includes a displaceable filling unit for filling the two juxtaposed bag items.
  • the choice of filling unit depends on whether it is the same articles that are filled into both bags, or alternatively whether the advantage achieved by the invention by the option of filling different articles into two bag items conveyed in parallel is utilised.
  • the apparatus may be peculiar in that the guide means include conveyor chains with projecting parts projecting freely from the conveyor chains and which can engage perforations or holes in respective peripheral areas, a guide channel that can engage a bead in respective peripheral areas, guide rails that can engage a channel in respective peripheral areas, or squeezed chains or belts that can engage respective peripheral areas by friction.
  • the guide means include conveyor chains with projecting parts projecting freely from the conveyor chains and which can engage perforations or holes in respective peripheral areas, a guide channel that can engage a bead in respective peripheral areas, guide rails that can engage a channel in respective peripheral areas, or squeezed chains or belts that can engage respective peripheral areas by friction.
  • the bag web may be peculiar in that the peripheral areas at the outermost opposite bag opening edges of two juxtaposed bag items are joined by welding or welded together with the central support region.
  • the bag web may be peculiar in that the peripheral areas at the outermost opposite bag opening edges of two juxtaposed bag items are joined by welding or welded together with the central support region.
  • the bag web may be peculiar in that the peripheral areas at the outermost opposite bag opening edges of two juxtaposed bag items are free peripheral areas. This simplifies the bag production.
  • the bag web may be peculiar in that the bag web is formed of a film web which is folded about folding lines in longitudinal direction of the bag web, the folding lines disposed with a spacing largely corresponding to one fourth of the width of the film web from each side edge of the film web for forming the two juxtaposed bag items.
  • the two juxtaposed bag items can thus advantageously be made from one film web without any need of combining several film webs.
  • the bag web may be peculiar in that the peripheral areas of the bag web at the outermost opposite bag opening edges of two juxtaposed bag items are each provided with a series of perforations for the guide means in an apparatus according to the invention. Secure and firm gripping of the peripheral areas is hereby achieved.
  • the bag web may be peculiar in that the peripheral areas of the bag web at the outermost opposite bag opening edges of two juxtaposed bag items are each provided with a longitudinal bead for engaging the guide means in an apparatus according to the invention.
  • the guide means will include a channel or a chain which by friction can grip around the bead.
  • the bag web may be peculiar in that the peripheral areas of the bag web at the outermost opposite bag opening edges of two juxtaposed bag items are each provided with a longitudinal channel for engaging the guide means in an apparatus according to the invention.
  • the guide means will include guide rails that can be received in the channels and thereby provide secure guiding of the peripheral areas.
  • Fig. 1 shows prior art and serves to illustrate a principle for designing peripheral areas at the outermost opposite bag opening edges and guide means adapted to retain and guide the peripheral areas at the opposing bag opening edges.
  • Fig. 1 is shown that from a supply roll 2 a film material web 4 can be unrolled, consisting of a double film folded around a bottom edge 6 and joined along the upper edge by a simple welding 8, without any foldings or thickenings of any kind. Therefore, it may also be a tubular film.
  • a series of slits 10 that extend from the bottom edge 6 up to a point below the upper edge 8 so that the web appears with mutually separate bag items 12, the side edges of which closed by weldings 14.

  • peripheral areas 40 of the web are penetrated by a single row of perforations 18.
  • the support bar 20 has an upwardly projecting cutter member 24 which by advancing the web will continuously cut the upper edge of the latter, and thereafter is arranged a continuing carrier system consisting of opposing parallel chain runs 26 that are made with upright holding studs 28 for engaging holes 18 in respective top parts of the web that are laid out at both sides, and by a pressing roller 30 which after threading the film web in provides for drawing down the said unfolded upper edge areas of the web 4 towards the firmly supported carrier chains 26 for horizontal bearing against the top sides of the latter, and thereby under pivoting down of the holes 18 in such a way that the holes 18 are pivoted down and engage over the chain studs 18.
  • the pressing roller 30 has turned-in grooves 32 for enabling free passage of the outer end parts of the chain studs 28, and in these grooves there are embedded transversely positioned studs (not shown) which like a cogwheel can interact with the chain studs 28 for automatic synchronous driving of the pressing roller 30.
  • the opposing upper edge parts of the web 4 will then be securely anchored to the carrier studs 28, and the carrier chains may then be guided through a desired course for successive opening of the bag items as indicated by 34, whereby they can be filled by a filling apparatus 36 disposed above the open bag item and for closing the items after filling thereof.

  • Fig. 2 shows an apparatus according to the invention, wherein a bag web with two juxtaposed bag items 12 is used. At the outermost peripheral areas 40, the bag items 12 are penetrated by perforations 18 that enable fastening to the retainer studs 28. At the bag sides which are disposed close to each other, the peripheral areas of the bag sides are formed of a central support region 42 extending longitudinally of the bag web. The central support region 42 is placed on the support rail 20. According to the invention, the support rail 20 is extended compared with the length shown in Fig. 1 . The support rail 20 will therefore extend along the conveyor path through a filling station 44 where the filling apparatus 36 is provided.
