Definitions

  • the invention relates to a device for producing reclosable tubular bags after the Preamble of claim 1, as for example from the EP 0 410 126 A1 has become known.
  • a device for producing reclosable tubular bags after the Preamble of claim 1 as for example from the EP 0 410 126 A1 has become known.
  • the clockwise working known device is during the Standstill phase of the film feed Sealing tape section on the flat top of the film web attached to. Then the flat film web is inserted Hose shaped.
  • the fastener tape section over the entire surface Sealed inside of the hose.
  • the fact that the Sealing tape section during the standstill phase of the Foil feed must be fed and attached is the Performance of the known device is limited because the Cycle time from the time required to attach the Closure tape section depends. Furthermore, one continuous operation with the known device not possible.
  • the inventive device for producing reclosable tubular bags with the Features of claim 1 has the advantage that it enables particularly high performance.
  • a synchronous movement of the transverse seam sealing device and the device for attaching and attaching the Closure tape can be achieved if the two Facilities are coupled together.
  • known per se Tubular bag pack 1 has an upper transverse seam 2, one lower transverse seam 3 and one in the middle of a side surface running longitudinal seam 4. Slightly below the top one Cross seam 2 is a section 5 of a reclosable Band 6 arranged.
  • the band 6 has two positive interacting parts 7, 8, of which one part 7 in two areas 11, 12 with one inside 13, and the other part 8 with an area 14 with the opposite inner side 15 of the tubular bag pack 1 is connected by sealing.
  • the upper transverse seam 2 is preferred as so-called peel seam formed.
  • it would be however also conceivable between the upper transverse seam 2 and the Volume 6 form a weakened area so that the corresponding upper section of the tubular bag pack 1 is easy to tear open or tear off.
  • tubular bag pack 1 takes place schematically on one in Figures 3 and 4 shown, continuously working vertical Tubular bag machine 17.
  • the tubular bag machine 17 has for forming the tubular bag packs 1 from one Packing material web 18 has a shaped shoulder 19, which in the usual way is connected to a shaped tube 20.
  • Below the The shaped shoulder 19 is on the shaped tube 20 Longitudinal seam sealing device 21 for forming the longitudinal seam 4 arranged.
  • Is located below the shaped tube 20 still an up and down movable cross seam jaw housing 22 with two cross-seam sealing jaws 23 which can be moved relative to one another, 24.
  • the transverse seam sealing jaws 23, 24 serve to form the Cross seams 2, 3, areas 11, 14 of the Band 6 against the inside 13, 15 of the Tubular bag packs 1 are sealed over the entire surface.
  • the stock roll shown are used in addition to those in system contact preferred bands 25 located with the shaped tube 20 continuously driven preferred rollers 26, 27 and Deflection pulleys 28.
  • a horizontally movable Feed roller 29 in the inlet area to the shape shoulder 19 provided that a format adjustment with respect to different Lengths of the tubular bag packs 1 allows.
  • the tubular bag machine 17 has on the packaging material web 18 a special device 30.
  • the in the area of a horizontal feed path of the Packing material tape 18 arranged device 30 has a a stepper motor 31 driven, stationary Roll pair 32, 33 on.
  • the side and above the Packing material strip 18 arranged roller pair 32, 33 pulls one at a time in accordance with the width of the bag 1 corresponding section 5 of volume 6 of one Supply roll 35 from. That of the roller pair 32, 33 pulled tape 6 is from a guide cassette 36th immediately above the packaging material web 18 and aligned, the longitudinal direction of the band 6 perpendicular to the packaging material web 18 and its feed direction 37.
  • the guide cassette 36 consists of two elements 38, 39, between which a separator 40 for cutting off the Section 5 of the tape 6 is arranged.
  • Section 5 is placed over the packaging material web 18 that on both sides section 5 each with a packaging material web area 41 a width of slightly longer than L / 4 (depending on the Bag shape) remains.
  • the element 39 is designed such that the area 12 of part 7 the element 39 on the side facing the shaped shoulder 19 protrudes laterally.
  • a synchronous horizontal movement of the two Sealing jaws 44, 45 with the continuous To cause feed movement of the packaging material web 18 is Fastening device 43 with the transverse seam jaw housing 22 coupled.
  • the coupling takes place, for example, by means of a Timing belt 46, which is guided over a deflection roller 47.
  • the toothed belt 46 causes the sealing jaws 44, 45 at a downward movement of the transverse seam sealing jaws 23, 24, which with the feed rate from the Packing material web 18 molded hose is carried out with the same speed and in sync with that of the Guide cassette 36 facing end position in its other Bring end position.
  • the tubular bag machine 17 described above works as follows: The of the preferred rollers 26, 27 continuously pulled-off packaging material web 18 passes over the deflection rollers 28 and the feed roller 29 to the mold shoulder 19.
  • the mold shoulder 19 places the two edge-side packaging material web areas 41 forming a hose against each other, the Packaging material web areas 41 in the area of the longitudinal seam 4 overlap.
  • the overlapping area is on the further
  • the conveying path of the packaging material web 18 to the longitudinal seam 4 is sealed.
  • the transverse seam sealing jaws are located below the shaped tube 20 23, 24 move against each other if that Cross seam jaw housing 22 moved down.
  • sections 5 of volume 6 to the Packing material web 18 takes place in two steps: during the above mentioned downward and upward movement of the Cross seam jaw housing 22 is driven by stepper motor 31 each have a section 5 of length L in the element 39 of the Guide cassette 36 inserted by the Separating device 40 is separated from the belt 6. Essential is that section 5 is separated from tape 6 if the fastener 43 in its the Guide cassette 36 facing end position. Now the two sealing jaws 44, 45 against the film web 18 move so that the area 7 of section 5 in System contact with the sealing jaw 44 and the top of the Film web 18 arrives. This takes place immediately in the Wait when the cross seam jaw housing 22 den top reversal point has passed.
  • the Fastening device 43 In the subsequent Downward movement of the cross seam jaw housing 22 is the Fastening device 43 by means of the toothed belt 46 in the Feed direction 37 moves, the against each other driven sealing jaws 44, 45 section 5 from the Pull out element 39 of guide cassette 36. While this movement of the fastening device 43 is the Area 7 of section 5 under the influence of heat and Pressure sealed against the top of the packaging material web. The Sealing process is before reaching the lower turning point of the transverse seam jaw housing 22 ended, whereupon the two Sealing jaws 44, 45 can be opened again. In the subsequent upward movement of the cross seam jaw housing 22 the fastening device 43 becomes tension spring 48 back into the end position facing the guide cassette 36 brought back, whereupon the operations as above repeat as described.
