Definitions

  • the invention relates to an apparatus for packing articles or bundles of articles, comprising means for continuously feeding the articles to be packed in spaced apart relation, means for the continuous supply of a continuous web of packing material, means for wrapping said material around the articles, means for advancing the wrap, means for adhering the longitudinal sealing seam portions to each other, and means for forming the transverse sealing seams and severing these seams.
  • Such an apparatus is known from US-A-3420035 and is called a flow pack apparatus.
  • US-A-3397505 discloses a perforating device in a packaging machine for developing a series of slits extending in the longitudinal direction, adjacent the folded edge of a folded web, which slits assist the subsequent opening of the folded web, said perforating device comprising two rollers driven in synchronism and of which one roller is formed by a serrated roller knife and the other roller provides an anvil.
  • a perforated line is produced in the web which extends in parallelism with the direction of advance of the web.
  • the rotational velocity of the two rollers driven in synchronism should be adaptable to the varying velocities of the web of packing material at the movement at which the perforating knife cooperates with the anvil, since the perforating knife together with the anvil should have nearly the same velocity as the web of packing material during their cooperation, as otherwise the web of material would tear.
  • a perforating device is provided consisting of two rollers driven in synchronism, of which the one roller is provided with at least one perforating knife and of which the other roller is provided with at least an anvil for cooperating with the perforating knife, and means for guiding the web of packing material between said rollers.
  • rollers are in driving connection with each other, while one of said rollers is in driving connection with a crank mechanism the connecting rod of which is coupled at its other end to a second crank mechanism which is in driving connection with a driving shaft of the packing apparatus, one of the crank mechanisms being mounted for displacement so that the axis of the pivot shafts of the two crank mechanisms may be displaced in parallel relation with respect to each other.
  • the driving shaft is coupled to the second crank mechanism by means of a chain, means being provided for adjusting the position of the second crank mechanism with respect to the driving shaft. In this way the location at which the perforation line is formed on the packing material may be adjusted.
  • the packaging material is coated by a fusible sealing agent which agent is subsequently heated for sealing by fusion the perforations.
  • the package comprises a sheet of packing material enclosing the article, said material being closed by means of a longitudinal sealing seam 1 and two transverse sealing seams 2 and 2'.
  • a perforated line is indicated formed in the packing material and extending around the article except for the upperside along which the longitudinal sealing seam extends.
  • a cap-shaped portion 4 may be torn off.
  • the perforated line 3 may be folded downwards along a pivot line extending in the plane where the perforated line does not extend, so that the article 5 may be removed from the package, while the exposed portion of the article if eatable may be bitten off, whereafter the cap-shaped portion 4 may be folded back again.
  • the device for producing a perforated line in the web of packing material comprises two rollers 6 and 7 of which the roller 6 is provided with a perforating knife 8 capable of cooperating with an anvil 9 in the roller 7.
  • the perforating knife 8 is supported within the roller 6 through taps 10 by springs not shown.
  • the rollers 6 and 7 are journaled in the arm 11 fixed to the upright 12 of the packing apparatus.
  • On said upright 12 a further arm 13 is fixed in which a roll of packing material 14 is supported. From said roll 14 the web packing material 15 is guided through guiding means 16, 17 and 18 between the rollers 6 and 7 and thereafter over the guiding means 19 and 20 to the proper packing portion of the packing machine.
  • the rollers 6 and 7 are connected with the shafts 21 and 22 respectively on which intermeshing gears 23 and 24 are provided.
  • the ends of the shafts 21 and 22 are supported in the arm 25, through which the shaft 21 continues and is coupled with a first crank 26.
  • Said first crank 26 is driven by the connecting rod 27, the other end of which is connected with a second crank 28 being driven through the chain sprocket 29 and the chain 30 by the driving shaft 31 (see fig. 7).
  • the second crank 28 is provided with a stub axle 32 received for displacement in the plate 33, in which said stub axle 32 is fixed by the nut 34 so that after releasing said nut 34 said stub axle can be shifted up and down by means of the screw 35 with the actuating wheel 36, by which the axis of the pivot shaft of the second crank 28 can be displaced in parallel relation with the pivot shaft of the crank 26.
  • cranks 26 and 28 The operation of the cranks 26 and 28 is illustrated schematically in fig. 6, in which the first crank is indicated by the line 26', the second crank by the line 28' and the connecting rod by the line 29'.
  • the axis of rotation of the second crank is M and that of the first crank N.
  • By rotating the second crank 28' its end a moves along the circular path 37, in which the movement of the crank is uniform as indicated by the points b, c w, x, which points are equally spaced apart, while for covering the distance between each two points the same time is necessary.
  • the end a' of the crank 26' will move along the circular path 38 and will be positioned at the moments determined by the points a, b .... w, x at the points a', b' ....
  • rollers 6 and 7 are not driven directly through the crank mechanism 26, 27 and 28 but through a deceleration mechanism, for example consisting of intermeshing gears, which deceleration mechanism is arranged between the crank mechanism 26, 27 and 28 and the driven shaft 21 so that along two or more parts of complete revolution the rollers 6 and 7 obtain the velocity distribution produced by the crank mechanism 26, 27 and 28 as shown in fig. 6, so that two or more perforating knifes and cooperating anvils can be mounted in the rollers 6 and 7 respectively.
  • a deceleration mechanism for example consisting of intermeshing gears
  • the chain sprocket 29 is driven through a chain 30 by the driving shaft 31, said driving shaft making a complete revolution for each product passed through the packing apparatus.
  • the chain 30 is guided through two fixed guiding wheels 37 and 38 along two displacable guiding wheels 39 and 40 to the chain sprocket 29.
  • the guiding wheel 39 is journaled in a pivotable arm 41, which arm can be moved up and down by means of the threaded rod 42 and the actuating wheel 43.
  • the guiding wheel 40 is supported in a pivotable arm 44 to which a spring 45 is fixed, by which the guiding wheel 40 is always maintained in engagement with the chain 30.
  • the position of the guiding wheel 39 is varied, by which also the guiding wheel 40 is displaced and the chain sprocket 29 is rotated with respect to the driving shaft 31, by which the locations where the perforated lines are formed onto the packing material can be adjusted.
