Definitions

  • the present invention relates to a method for using the bottom seam on a Folding organs equipped pouch packaging machine manufactured stand pouch fold and pin to the bottom and a device for carrying out the Method as defined in the preamble of claims 1 and 2, respectively.
  • Stand-up pouches are, in the sense this invention, such bags, which, starting from a flexible film web, on a likewise known bag packaging machine equipped with folding members getting produced. They are characterized in that they have a flat bottom have, in the sense of a footprint, and are therefore able to stand upright Take position and keep stable. Bag packaging machines like those for the production of such stand-up pouches are best in practice known, as well as the corresponding stand-up pouches. It’s machines, which are also known in the patent literature (see, inter alia, DE-C 303 1399) and are equipped with special folding elements.
  • Such bag packaging machines basically consist of a housing in which the working elements are fixed.
  • the most important organs are the film web feed with film roll and guide and conveyor roller, the so-called format set with filling tube for filling the product in from a flexible film web to be manufactured bag and a shape shoulder, about which the film web is pulled to form a tube, a Longitudinal closing device to produce the longitudinal seam of the bag and a Cross closure device to create the cross seam, i.e. the bag too closure.
  • these organs which are present in every bag packaging machine are, come, in the case of the production of stand-up pouches, additional, too known folding organs, which have the function of the bag after the filling tube to deform and give it a rectangular footprint.
  • the end of the filling tube is not round (as is usual for normal "pillow bags"), but shaped rectangular, which helps to produce the stand-up pouch. That is all however state of the art and is carried out in practice on an ongoing basis and therefore needs not to be explained in detail here.
  • the present invention is concerned not with the formation of the stand floor and with the necessary facilities in a bag packaging machine, which must be considered known, but specifically with the folding and tacking of the bottom seam to the bottom itself, so that the bottom results as flat as possible and the bottom seam does not interfere when placing the bag on a surface. It is about So here it’s just a matter of tacking the bottom seam to the bottom of the bag.
  • the bottom seam is folded using sliding plates or with an air jet (so-called air allocation). With this method it is possible fold the bottom seam, but not pin it to the bottom of the bag.
  • the expert knows from a known bag packaging machine (so-called Butler 3 from PMB-UVA, NL), a reassembly and attachment technology, which is that after the cross-lock device is made the bottom seam and the previous bag has been dropped, the entire format set is pneumatic is lowered onto the cross-locking device.
  • the closing device is warm, the bottom seam is folded over and tacked to the bottom, because the film material becomes thermally soft (it is usually a Plastic film).
  • the present invention aims to overcome the above drawbacks of the prior art To fix technology and to propose a method and the corresponding device, which is the production of a perfectly folded and tacked bottom seam allow a stand-up pouch, and this without restrictions on the production of Machine and with high precision the movements of the elements involved Machine.
  • the machine should also be simple and cheap.
  • the main feature of the invention is in the vertical movement of the locking tools between one lower closing position and an upper tacking position and vice versa. Thanks this movement - and assuming a systematic folding of the bottom seam - you can attach the bottom seam precisely and quickly to the bottom of the bag without - as known from the prior art - lower the entire format set and to have to lift.
  • Fig. 2, 1 is the shoulder of a so-called format set 2, on which the Packaging film is converted from a flat film to a tube. 3 with a funnel is designated, which with the filler tube 4 below connected is.
  • the hopper 3 receives the material to be packaged from the balance (not shown) and forwards it to the filler pipe.
  • the filler pipe 4 is open at the bottom and can have a square cross section in its lower part exhibit; this is not a requirement if the machine is for normal production Pillow bags are provided.
  • the machine as in the case of the present Invention
  • the filler tube 4 at its lower, open end 5 a rectangular cross section, because to create better conditions for a stand-up pouch.
  • the cross section of the filler tube changes from its upper part to its lower part gradually from the round to the rectangular shape.
  • this is for the present invention is not relevant.
  • the entire format set 2 is fixed on a yoke 6, which has two vertical supports Columns 7 (only one of them is visible) connects to one another and no further shown frame of the machine belongs.
  • the longitudinal closing device 9 consists essentially of two tools, one heated, vertical lying tool 11 and a fill pipe counter holder 12.
  • the two tools 11 and 12 lead a common, opposite movement to the filling pipe 4 out. Their function is to seal the longitudinal seam of the bag. All of this is conventional and has nothing in common with the present invention.
  • the method, like the tools 11 and 12 of the longitudinal closing device synchronously with one another moving to and from each other is not critical to the present invention.
  • the transverse closing device 10 is also, in principle, of conventional construction, to however to a point which plays a crucial role in the context of the present Invention plays and therefore deserves special attention.
  • the cross locking device 10 basically consists of two horizontal, heated tools 18 and 19 conventional design with folding elements, which are in a horizontal Plane can be moved to and from each other using suitable drive means. These tools 18 and 19 can also be equipped with guides, racks and pinions, similar to the tools 11 and 12 are driven. For them, too, is the way they are driven to the closing movement, not essential to the invention, provided it is an efficient and low-mass method.
  • the cross closure device 10 has means for movement of the cross locking tools also in the vertical direction to open and close Downward movement, is equipped. This, to the actual closing movement in The horizontal level additional movement is critical to the realization of the inventive goals, as will be shown later.
  • a preferred type of this additional movement device is shown in Fig. 1 as an example.
  • the tools 18 and 19 are with horizontal guides (only the guide 20 of the tool 19 is, however, shown in Fig. 1), which in one Carriages 21 are let in.
  • the carriage 21 is a plate which in the two vertical, parallel guides 8 is guided.
  • With two pinions, not shown, which engage in a corresponding rack of each guide 8 can now Carriage 21 by means of a motor 22 up and down, that is up and down, be moved by motor.
  • This vertical movement of the locking device 10, which are basically realized with other drive methods can, is critical in the present invention as it is closer to be explained. It is understood that such an up and down movement with drive means other than those described can be implemented, the described Solution, as experience has shown, offers the important advantage of mass poverty.
  • Figures 2a and 2b show in a detailed representation the specific for Forming a stand-up pouch necessary for the machine's work organs: this affects above all the cross-closure device 10, which must be equipped with folding members.
  • FIGS. 2a and 2b show the cross-locking device in the open state.
  • the locking tools are further designated, while with 23 and 24 the folding organs are indicated.
  • the folding members move transversely to the closing tools 18 and 19, driven by suitable drive elements in synchronism with the Closing tools 18 and 19.
  • the folding corners 25 form the for molding of the bottom of the next bag folds, while the folding fingers 26 upside down fold the previous filled bag. This technique of forming a stand-up pouch is known to every specialist and does not need to be specifically explained here.
  • FIGS. 3a and 3b 18 and 19 The folding members 25 and 26 and the closing tools are shown in FIGS. 3a and 3b 18 and 19 in the closed position, i.e. during the sealing of the Bottom seam of the next bag and the top seam of the previous bag, shown.
  • FIGS 4a to 4h now serve to explain the inventive method steps. Only the elements necessary to describe the process are shown are, the folding members 23 and 24 (with the folding fingers 26 and the folding corners 25) have also been omitted because they are narrow, as shown in Figures 2 and 3 are connected to the transverse locking device 19 and in particular their must follow vertical movement.
  • the procedure relates to the reallocation and Attach the bottom seam to the bottom of a stand-up pouch and therefore does not fall into it Concerning the formation of the stand-up pouch itself. This happens namely after conventional Type and is not the subject of this invention.
  • FIG. 4a shows the first step of the method.
  • the Bottom 27 of the next stand bag 28 to be refilled, folded and closed, what together - in one go - with the folding and closing of the Head seam 29 of the previous stand-up pouch 30 already filled occurs. Doing so a connecting web 31 between the previous stand-up pouch 30 and the next stand-up pouch 28 is formed.
  • FIG 4b shows the second step of the method.
  • the cutting knife 32 which is installed in the cross-closure device 10
  • the Connecting web 31 separated.
  • the two standing bags 28 and 30 are separated with the transverse closing device 10 closed.
  • FIG. 4c shows the third step of the method. This consists in the repatriation of the Knife 32 in its starting position (i.e. from right to left in Fig. 4c) at still closed transverse locking device 10. In this position, the previous one Stand-up pouch 30 still held.
  • the cross-locking device is now 10 opened, with which the previous standing bag 30 freed and dropped becomes. It has already disappeared in FIG. 4d.
  • the step is that one of the two locking devices (e.g. tool 18 in Fig. 4d) in the sense of its Distance from the other tool. It arises immediately, between the two tools 18 and 19, one gap, at least as large as the bottom seam width.
  • Fig. 4g Now comes the next process step, which is shown in Fig. 4g. Now will the cross closure device 10 is fully open, i.e. tools 18 and 19 are shifted in the opposite direction by a total distance (s), which is greater than the width (b) of the stand-up pouch 28. The bag 28 is now lowered in the closing position of the head seam and with the one to be filled Material filled, with which his head seam to lie in the position shown in Fig. 4a comes.
  • the cross-closure device 10 is again used lowered to its initial position and the cross-locking tools 18 and 19 are closed, so that the situation of Fig. 1a is reached again.
  • the cycle can with start closing the next top and bottom seam again.
  • the advantage of the inventive method lies in the fact that for the reallocation and tacking the bottom seam only small masses can be moved along small paths must, and this without having to move (lower) the format set 2.
  • the result is a higher output of the machine with a perfectly tacked bottom seam.
  • the device for performing the method has a format set 2 and a longitudinal closing device 9, which in the lower zone of the filling tube 35, is placed parallel to the axis of the tube and is equipped with means to the Longitudinal closing tools 11 and 12 a counter-rotating and synchronized To give movement to form the longitudinal seam. It also has a cross locking device 10, which is in the immediate vicinity of the free end 5 of the filling tube 35 is placed and equipped with means to the cross-locking tools 18 and 19 an opposing and synchronized movement up and down to Issue formation of the transverse seam of the bag, the transverse seam being both the head seam of the next bag as well as the bottom seam of the previous bag. Both are made at the same time, as is clear from the description of the method evident.
  • the device also has conventional folding members 23, 24 to create a flat one To produce the bottom of the bag 27.
  • These folding organs are immediately above and below on the cross locking tools 18 and 19 attached.
  • the inventive feature of the device now consists in the fact that the Means 20 for the opening and closing of the locking tools 18, 19 also one smooth and synchronized movement of the individual tools 18 and 19 allow - to perform the process steps of FIGS. 4e and 4F - and further in that means 22 are also provided for the entire cross-locking device 10 to move up and down vertically.
  • These means 22 can, in addition to the engine, other Include items such as gears, racks, etc.
  • each cross-locking tool 18, 19 with its own drive (not shown) for the opening and Movement is equipped, with all guides 20 together in one and movable carriage 21 are housed.
  • the drive of the cross locking tools 18 and 19 can be made using known means such as pneumatic or hydraulic Cylinder / piston systems (not shown) can be realized.
  • each guide 20 as a rack (not shown) is formed and by means of its own toothed pinion (also not shown) is opened and closed.
  • the vertical up and down movement of the locking device 10 a Distance of less than 6 mm.
  • the bottom seam length which only must be sufficient to cover the bottom seam length (strictly speaking, only part of the bottom seam length, since at the moment the bottom seam 34 is attached to the bottom 27, the bottom seam is already inclined by approximately 45 ° - see Fig. 4f) tacking on the floor plays one important role with regard to the rapid execution of the movement and thus to the Delivery of the bag packaging machine.
