Definitions

  • the invention relates to a method and a device for producing a single or multi-layer valve sack made of paper or film with a self-closing valve.
  • Paper valve sacks are widely used for packaging powdery or granular goods.
  • the spreadable or flowable material can be filled using automatic filling systems can be introduced, and the valve, which closes itself after the filling due to the pressure effect of the filling material, makes an additional operation for closing the filled sack mostly superfluous, or additional sealing leaves applied are considerably relieved by the self-closing properties of the valve.
  • the cross-bottom valve bag is of great importance. While the sewn sack on the one hand offers the advantage of inexpensive manufacture, there is the disadvantage, however, that such a sack is not absolutely tight. On the other hand, the cross-bottom valve sack has good tightness, but it is more expensive and requires more material to manufacture.
  • the invention has for its object to provide a method and a device using conventional sack machines, as possible, with which such proposed side gusset valve bags can be produced inexpensively with the valve inserted into the longitudinal seam of the bag hose.
  • Claim 2 specifies an advantageous further development of the inventive concept according to Claim 1, by means of which an adaptation of the manufacturing process to different format sizes of bags can be ensured.
  • a device according to the invention for the production of said bags with a self-closing valve is characterized in claim 3; and the further subclaims indicate advantageous configurations of the manufacturing device according to the invention.
  • a valve manufacturing unit is arranged above the material web guide in which is produced from a supply roll from paper valves and is fed into the open, pre-glued blind path positioned in defined areas.
  • the prefabricated paper valves are contacted with the pre-opened open sack track and, after the valve has been applied, the sack track with valve passes through a pressure section with which the supplied valve cuff is securely bonded.
  • FIG. 1 shows a basic illustration of a transport device for a sack track with a device arranged above it for producing a valve sleeve; 2 to 6 basic representations of partial areas of the device for producing the valve sleeve and FIG. 7 serves to illustrate the individual method steps in the manufacture of a valve sleeve.
  • a sack path 1 which can be referred to as an open sack path in a single-layer sack or which represents the inner sack path in the case of a multi-layer sack, is first deflected on a roller 4 and pre-glued in a glue status B in the area of the subsequent valve applications.
  • the glue station B consists essentially of a glue pan 5, a scoop 6 and an applicator roller 7 suitable for a format-based glue application.
  • a deflection roller 3 in turn ensures a deflection of the open blind web 1.
  • a valve or a valve sleeve 24 is applied and when a pressure roller pair 18 passes through, the blind web 1 and the applied valve sleeve become pressed together for an intimate bond.
  • a deflection roller at the intermediate product discharge or at the transition to a Sac Accordingly, the manufacturing machine reaches the open blind path with the valve attached.
  • a conveyor belt 17 runs around in the area of a pressing station 13, and a cylinder_erl3b, which at the same time ensures the application of the valve sleeve 24 to the open blind path 1, serves on the opposite side of a cylinder 13a as a deflecting roller for one or several conveyor belts 17.
  • valve shaping and application device to be described below comprises the following structural units:
  • a roll 22 represents the material supply roll for a valve path 8, from which the valve sleeves 24 are produced, as will be described in more detail.
  • a traction mechanism is outlined, which ensures that the valve train 8 is transported in format.
  • a cross cutter 9 with a cutting knife 14 which is attached to an upper roller 9a, a lower roller 9b acting as a counter pressure roller, the valve path 8 after the
  • a pulling group 21 ' serves for the further transport of the valve blades 24' which occur one after the other, and the roller groups 10, 11, 12 successively perform a first folding, area-by-area gluing, a second folding and folding the valve blades 24 'into one Valve 24 in the form of the number "9" and finally the transfer of the finished valve sleeve 24 to the transfer cylinder 13b already mentioned.
  • FIG. 2 first illustrates the operation on the isolated valve sheet 24 * when it reaches the folding group 10.
  • the lower folding cylinder 10b carries two folding flaps 16a and 16b, which are controlled via cams and control cams 15a, 15b ' .
  • 2 further shows that the isolated valve sheet 24 'has been grasped by the front folding flap 16a of the folding cylinder 10b just behind the leading paper edge, so that a front flap 24a of the valve sheet 24' has erected.
  • FIGS. 3 and 4 solely with the glue application roller 11c. 1 shows, however, that the glue unit 11 also has a glue box 11a and a scoop roller 11b.
  • FIG. 4 it can be seen that when the folding cylinder 10b is turned further, the folding flap 16a has now opened, while the folding flap 16b has now gripped the still open valve leaf 24 ', due to the inherent stiffness of the paper to erect a flap 24b comes, which in turn angled in the opposite direction carries the backward inclined tab 24a.
  • the valve sheet 24 ′ which is still open, passes through the nip 31 between the folding cylinder 10b and a gripper drum 12, the tab 24b now leading is completely folded over, the tab 24a being open the glue track 23 comes to rest.
  • the valve which is still lying flat, but in principle already 9-shaped, is now fully folded.
  • the gripper drum 12 now grips with the gripper 25 the valve sheet 24 'on the folding drum 10b, and finally, as shown in FIG. 6, the finished valve sleeve 24 is transferred from the gripper drum at the point of contact of the rollers 12 and 13b 12 on the transfer cylinder 13b.
  • a gripper finger 25 (not shown in detail) must open at this transfer point; at the same time, the flat-lying valve sleeve 24 is easily grasped by a fine needle 20, which is attached to the transfer cylinder 13b, and the actual transfer of the finished fold.
  • the valve sleeve 24 to the transfer cylinder 13b is provided by a suction cup 19, which is connected to a vacuum pump, which is not shown in more detail.
  • the vacuum is switched off by the suction cup 19, so that, supported by the belt or belts 17, the valve sleeve 24 is transferred from the transfer cylinder 13b to the previously described one with the gluing unit 5, 6, 7 in sections remindlei te sack track 1 can be done.
  • the upper folding cylinder 10a preferably has two folding knives (not shown in more detail) which, when the open valve sheet 8 passes through the nip 30 between the two folding cylinders 10a and 10b, ensure that the valve sheet 8 of the two folding flaps 16a and 16b is in the lower one Folding cylinder 10b is detected.
  • a clock control is to be provided in such a way that the folding flaps 16a and 16b each before entering the nip 30
  • the valve manufacturing unit can therefore also be equipped with two folding knife cylinders, so that the folding cylinder 10a has only one folding knife with which the secure gripping of the valve sheet 8 by the folding flap 16a can be ensured.
  • the separated valve sheet 24 * which is gripped only in this way with a folding pliers, then only passes through the glue station 11 before the gripping of the valve sheet 24 'is ensured by the folding pliers 16b with a second folding cylinder (not shown in more detail).
  • a second folding cylinder not shown in more detail
  • FIG. 7 again illustrates the individual process steps for producing the 9-shaped valve in perspective single images.
  • FIG. 7a shows the valve sheet 24 'which is still unfolded but has already been separated from the valve track 8, as it passes through, for example, in the region of the train station 21'.
  • 7b illustrates the valve sheet 24 'after the first folding in the folding flap 16a of the folding cylinder 10b, the front flap 24a being formed.
  • FIG. 7 c shows the valve sheet 24 ′, which has been pre-folded once, with the front flap 24 a after passing through the glue station 11, which has carried out the application of the glue track 23.
  • 7d finally shows the valve sheet 24 'after the second folding in the folding flap 16b, so that the valve sheet 24 * with the large tab 24b and the small tab 24a can now be clearly seen.
  • the valve 24 finished in FIG. 7e is finally applied to the blind web 1 provided with the glue traces 26 according to FIG. 7f, and FIG. 7g shows the open blind web 1 with the valve 24 applied, as is the combination of the blind web 1 with valve 24 after passing through the pressure roller pairs 18.
  • a clock control can be provided for the valve manufacturing unit such that, for example, the further transport of the separated valve sheets 24 'by the train group 21 is synchronized with the changeable sack size.
