Definitions

  • the invention relates to a bag machine for the production of bags of paper material according to the preamble of claim 1 and a method for the production of bags of paper material according to the preamble of claim 9.
  • Pouch machines usually initially comprise an unwinding device in which web-shaped paper material is withdrawn. The material is then fed in a transport direction of the actual bag machine. In a first processing step, which is carried out in a corresponding station, the web material is provided with transverse perforations or cross sections, so that lines of weakness arise.
  • a cutting and / or perforation tool is usually applied to a rotating shaft. This tool dips into the sheet-like material, which runs over a counter roll, whereby the lines of weakness arise. Along these lines of weakness, the paper material can be separated into sections. The distance between two lines of weakness thus determines the length of the bag.
  • the separation into sections is usually carried out after passing through a hose forming station, in which the side regions of the web-shaped paper material to form an overlap region turned over and in which the facing sides of the overlapping area are joined together, for example by applying a suitable paper glue.
  • the wall of the tubing comprising the longitudinal seam formed in this way is generally referred to as the upper wall of the tubing or of the tubing section. Accordingly, the other wall is referred to as the bottom wall.
  • the gusseting is preferably carried out together with the actual tube formation. Prior to folding into the hose, the subsequent overlap area must be covered with adhesive, such as starch glue, for a permanent connection.
  • the hose in the separating device is consequently separated along the weakening lines to form hose sections.
  • a single line of weakness can only have perforations, but it can according to the above-mentioned DE 35 29 746 A1 also include smooth cuts.
  • a weakening line comprises a plurality of sections which, as seen in the transport direction, occupy different positions, ie are offset from one another. The course of the weakening line is chosen so that the forward end of the lower wall projects beyond the leading end of the upper wall. In this way it is possible, in the further processing process, to fold over the lower wall onto the upper wall, so that the inner side of the lower wall comes to rest on the outer side of the upper wall. For the actual bottoming the part to be folded is provided with glue before folding. At the trailing, open in the later bag end, the upper wall then dominates the lower wall.
  • a section of the upper wall is additionally removed before or during the separation process to individual tube sections, so that even at the trailing end of the lower wall projects beyond the upper wall.
  • the part of the one wall projecting beyond the other wall is called a tab.
  • the wall whose trailing end is the tab referred to as the first wall, this being irrespective of whether the wall is the upper or the lower wall.
  • bags are produced for numerous applications. If a good to be transported filled in the bag, such a bag is usually closed. Often, after filling, the upper end is often simply turned over, folded several times or rolled. In order to avoid an independent resetting of these folds, these folds are often secured with an adhesive film strip which is applied by hand. It has been recognized that adhesive film strips are often out of reach when needed. Therefore, bags are known on which an adhesive surface has already been applied to an outer wall during the manufacturing process.
  • the protective layer protecting the adhesive surface for example a coated piece of paper that has little adherence, must be peeled off and the open end of the bag must be turned once so that the outer wall subsequently rests on itself or on the flap the adhesive surface rests. It is important to ensure that the end of the bag just exactly covers the adhesive surface. If the end has been folded over too short, areas of the adhesive surface are not covered. If, on the other hand, the ending has been folded too far, the end itself is not fixed. Therefore, the bag can be unintentionally reopened, for example, when it gets stuck on other objects.
  • the DE 43 14 685 A1 proposes a machine and a method for the production of bags, so that the bag no longer have the disadvantages mentioned.
  • a device for applying adhesive surfaces is provided on the paper material in the machine, with each of which an adhesive surface can be applied to a portion of the paper material, which is the other wall facing side of the tab in the finished bag.
  • the adhesive surface is applied to the side of the tab that represents the extension of the inside of the wall.
  • the object of the present invention is therefore to propose an apparatus and a method with which the adhesive surfaces can be very easily applied to the material.
  • the means for applying the adhesive surfaces is thus upstream of the tube forming device.
  • the paper material is still present as a web, so that all areas of this web are still accessible.
  • the entire surface can be reached, which later forms the insides of the bag walls.
  • the adhesive surfaces can be easily placed on the later inside.
  • the position of the adhesive surfaces is still freely selectable, since there are no geometric restrictions.
  • the position can be varied transversely to the web transport direction. This variation is particularly important when producing bags in which, as described above, the lower wall projects beyond the upper wall both at the front and at the trailing end.
  • a special feature in the said arrangement and procedure, ie the application of the adhesive surfaces before the formation of the tube, is that the adhesive surfaces are arranged before the separation of the tube into Schlauchabschrtitten within the tube.
  • the web runs on a roller which serves as a counter-blade to a cutting and / or perforating knife. Therefore, it is conceivable to apply the adhesive surfaces during the introduction of the weakening line.
  • the device for applying the adhesive surfaces of the apparatus for introducing the weakening line can optionally be done, so only if there is a need for such a device. This can also be done later.
  • the said device is very easy to reach and therefore very easy to maintain.
  • the web-shaped paper material passes through a glue application device, with which a glue trace is applied to the later covering area.
  • the material runs over a roller, which represents the counter layer for the glue application.
  • the device for applying adhesive surfaces may also be provided, which also uses the roller as a counter-surface. Therefore, it is of particular advantage to provide the device at this point.
  • a particularly preferred embodiment of the invention includes that the means for applying adhesive surfaces is synchronized with that of the device for generating the lines of weakness.
  • a start pulse is generated when introducing a weakening line.
  • a control device calculates the time at which the application of the adhesive layer has to be started and / or terminated. If necessary, the size of the adhesive layer is taken into account, for example, when so-called labels are to be used.
  • the adhesive surface is preferably applied in the region of the tab which is not covered by the gussets. So this is the part of the flap that is free of gussets.
  • the perforation contour so be designed that there is no gusset in the area of the adhesive surface.
  • the possibility of extending the adhesive surface also on the part covered by the side folds is also feasible and not detrimental. It can also be fixed gussets, which gives the bag closure extra durability.
  • At least parts of the device for applying adhesive surfaces are transversely displaceable.
  • two guides can be provided transversely to the transport direction of the web.
  • a motor-driven spindle-nut combination can be provided.
  • Fig. 1 shows sheet-like paper material 1 before the actual tube formation, which is guided in the transport direction x through the bag machine.
  • perforations 2 have already been introduced, which extend substantially transversely to the transport direction x. It can be seen that sections of the perforations in the transport direction x are arranged at different positions. Thus, the portion 2a is shifted relative to the sections 2b in the transport direction.
  • the longitudinal lines indicate the L jossfalzkanten 3 at. It can be seen in the figure that the offset of the sections 2a and 2b takes place in the region of these folded edges.
  • the fold lines 4, around which the web-shaped material is folded during tube formation when puncture-side bags are to be produced, are also shown in dotted lines.
  • the surface 5 denotes the inner side 5 of the lower wall.
  • the surfaces 6a and 6b represent the inside of the upper wall after the formation of the tube.
  • adhesive surfaces 7 are shown on the surface 6a.
  • the adhesive surfaces 7 are mounted on the paper material in such a way that, viewed in the transport direction x, they lie completely in front of the perforation section 2 b. However, it should also be relatively little surface between the adhesive surface 7 and the portion 2b, so that adhesive surface 7 and section 2b adjoin one another.
  • An adhesive surface 7 may additionally or alternatively be arranged on the surface 6b.
  • the double arrow y indicates that the adhesive surface can be displaced transversely to the transport direction x, if necessary, and can therefore be arranged at any desired location.
  • FIG. 2 shows the tube forming process.
  • the sheet-like paper material 1 is turned over.
  • the web edges 8a, 8b are guided by the guide elements so that they are placed on the surface 5, wherein folds along the Leksfalzkanten 3 arise.
  • the need for inserting gussets is known in the art and therefore will not be described here.
  • the extent of the adhesive surface 7 in the transport direction x is at most equal to the difference in the positions of the sections 2a and 2b. In this way, the adhesive surface is limited to the region of the tab 10, which in the FIGS. 3 and 4 becomes clear.
  • the FIG. 3 shows the tube 9, after which it has been separated into tube sections.
  • This separation is usually carried out in that the tube is passed through a first nip.
  • the rollers of a further nip following in the transport direction and having at least one length of hose section away from the first nip are driven at a higher speed than the rollers of the first nip. If the rollers of the further nip detect the leading end of the tube 9, this tears along the weakening line or perforation 2.
  • the leading end of the tube section which consists of at least one lower surface extension 5, is folded over and on the upper one Wall, which includes the surfaces 6a and 6b, fixed.
  • the folding edges 3 now form the longitudinal sides of the bag 11.
  • the projection of the perforation section 2a of the surface 5 and the perforation section 2b now delimit the tab 10, on the inside of which the adhesive surface 7 is now arranged.
  • FIG. 4 shows the same bag as the FIG. 3 , only turned around the longitudinal axis, so that the underside is visible.
  • FIG. 5 schematically shows a bagging machine 20 according to the invention.
  • the sheet-like paper material 21 is wound on a roll in the unwinding station 22 and is guided from there via deflection rollers 23 into the perforation station 24, not shown.
  • the web-shaped material passes onto a counter-roller 25.
  • This roller serves as a counter-position for the labeling station 26.
  • This station there is a roller 27 with a band, on which individual labels are applied, which are adhesive on both sides.
  • This tape is unrolled cyclically from the roll 27.
  • a single label is applied to the sheet-like paper material 1 at a predicted time.
  • the label for pressing the label in this case serves the pressing member 29, which is formed like a roll in the illustrated embodiment.
  • the tape which now carries no more labels, is then wound up on the roll 28 and can be disposed of there.
  • the sheet-like paper material provided with labels as described then passes into the hose forming station 30 (not shown in detail) and then into further stations for the production of the bags.
  • the rollers and rollers of the labeling station 26 are preferably drivable independently of the rest of the machine.
  • the drive is preferably controlled by the control of the bag machine.
  • a separate encoder for the drive is also
  • the labeling station can be provided as an optional attachment, which can be placed on the side walls of the machine frame of the bag machine.
