Definitions

  • the invention relates to a method for manufacturing packaging units in a tubular bag forming, filling and sealing machine, which method contains vertically conveying disk-shaped products, which lie one above the other in portion stacks, and wrapping them with a film web being conveyed parallel to the products by means of a film take-off device, wherein the film web, in order to form a film tube, is provided with a longitudinal sealed seam by means of a longitudinal sealing device and subsequently with transverse sealed seams above and below the portion stack by means of a transverse sealing device being driven by a transverse sealing drive device independently of the film take-off device and moving in the same direction as the film web while the sealing device contacts the film web for sealing purposes.
  • the film web initially being fed to a molding shoulder as a flat element is shaped, by means of the molding shoulder, into a plastic tube which has an overlapping longitudinal joint, and which serves for receiving products being conveyed to the film web in a fashion parallel thereto and lying one above the other in a portion stack.
  • transverse sealed seams are formed by means of a transverse sealing device for manufacturing a packaging unit that in each instance receives one or more portion stacks lying one behind the other in a row in the conveying direction.
  • One possibility of avoiding this undesired wedge effect is to maintain a sufficiently large space between the portion stacks being arranged in the film tube, in the conveying direction of the film web, when creating the transverse sealed seams, such that the tensile stresses that arise when creating the transverse sealed seams are reduced and thus the radial stress acting on the cookies also become correspondingly smaller.
  • a corresponding reduction of the filling degree of the individual packaging units and an increase in the consumption of film web are connected with this, such that, apart from a deterioration in the productivity of the production device, an increase in the manufacturing costs is also the result.
  • the present invention is therefore based on the task of proposing a method for manufacturing packaging units in a tubular bag forming, filling and sealing machine, which method allows for packaging that is gentle on the product at a high productivity of the production facility.
  • the transverse sealing device carries out a vertical movement relative to the film tube in the direction opposite the movement direction of the film tube while the sealing device contacts the film tube for sealing purposes.
  • an accumulation of the film tube results from the superposition of the vertical relative movement, which takes place in the direction opposite the movement direction of the film tube, the accumulation being located in the region between the transverse sealed seam and the portion stack being arranged above the transverse sealed seam. Said accumulation leads to the film tube remaining substantially free of tensile stresses in the region of the lower end of the respective packaging unit and to a limp bag gusset being formed.
  • the film tube is preferably cut through in the region of the transverse sealed seam, simultaneously to the transverse sealed seam being formed, it is avoided that, due to the accumulation, increased tensile stresses can arise in the region of the upper packaging end of the packaging unit being arranged below the transverse sealing device.
  • the relative movement of the transverse sealing device is effected by means of a retardation of the vertical movement of the transverse sealing device since the film web can thus be conveyed continuously and at a constant speed in the tubular bag forming, filling and sealing machine by means of the film take-off device and the required relative movement can thus be effected via a corresponding kinematic control of the transverse sealing device alone.
  • the movement distance s that is covered by means of the relative movement of the transverse sealing device is smaller than the space a between the transverse sealing device and the portion stack being arranged above the transverse sealing device.
  • FIG. 1 shows a transverse sealing device in a starting phase of contacting the film tube for sealing purposes
  • FIG. 2 shows the transverse sealing device being illustrated in FIG. 1 in a final phase of contacting the film tube for sealing purposes.
  • FIG. 1 shows a lower end of a film tube 12 being formed in a tubular bag forming, filling and sealing machine for wrapping disk-shaped products 11 lying one above the other in a portion stack 10 .
  • the film tube 12 by means of a film take-off device not being illustrated in more detail in FIG. 1 , is conveyed in the vertical conveying direction 13 to a transverse sealing device 14 , which comprises two sealing tools 15 , 16 being driven via a movement transmission that is not illustrated in more detail, such that the same rest, with sealing surfaces 17 , against the film tube 12 being arranged between the sealing tools 15 , 16 while contacting the film tube for sealing purposes, said contact being illustrated in FIG. 1 .
  • the sealing tools 15 , 16 are in a portal position which is illustrated in FIG. 1 in dash and dot lines, and in which position the sealing tools 15 , 16 are moved apart, such that the film tube 12 , with the products 11 being received therein, can pass through the sealing tools 15 , 16 of the transverse sealing device 14 .
  • the movement drive of the sealing tools 15 , 16 is formed such that the sealing tools 15 , 16 , in their sealing position being illustrated in FIG. 1 , are moved, by means of a drive device not being illustrated in more detail, in the conveying direction 13 of the film tube 12 while contacting the film web for sealing purposes. Afterwards, the sealing tools 15 , 16 are moved back into the portal position and around the movement path being performed in the conveying direction 13 during contacting for sealing purposes in the direction opposite the conveying direction 13 of the film tube 12 , in order to be transferred, in a subsequent sealing process for creating a transverse sealed seam 18 , into the sealing position being illustrated in FIG. 1 again.
  • the film tube 12 is cut through in the region of the transverse sealed seam 18 by means of a cutting device 19 being integrated into the transverse sealing device, such that a packaging unit 20 being defined in its length by two adjacent transverse sealed seams 18 is torn off from the film tube 12 .
  • the products 11 being illustrated in FIG. 1 by way of example are sandwich-like cookies, which receive a cream filling 23 between surrounding cookies 21 and 22 .
  • the cream filling 23 of the products 11 being fed to the tubular bag forming, filling and sealing machine immediately after a baking process is still relatively soft, such that radial stresses acting on the sandwich cookies 21 , 22 can easily lead to a deformation or to the cream filling 23 oozing out of the product 11 .
  • the sealing tools 15 , 16 of the transverse sealing device 14 in a final phase of the contacting for sealing purposes, carry out a relative movement subsequently to an at least partially material connection of film web portions 28 , 29 that rest against one another, for forming the transverse sealed seam 18 , said relative movement having a movement path s, in order to move the sealing tools 15 , 16 from the starting phase of the contacting for sealing purposes being illustrated in FIG. 2 in dash and dot lines in relation to the film tube 12 in the direction opposite the conveying direction 13 of the film tube 12 .
  • said relative movement is carried out by a retardation of the transverse sealing device 14 being moved in the same direction as the film tube.
  • the movement distance s being covered by means of the relative movement of the transverse sealing device 14 is smaller than the space a between the transverse sealing device 14 and the portion stack 10 being arranged above the transverse sealing device 14 .
  • folding pushers 27 , 28 are provided in each instance above and below the transverse sealing device 14 , being pivotable into the film tube 12 at an angle to the conveying direction 13 of the film tube 12 , and allowing for a defined formation of a gusset fold, such that the film web portions lying opposite to one another, in the region of the bottom gusset, lie one above the other in a fanfold fashion and such that a correspondingly defined formation of the transverse sealed seams is possible.
