Definitions

  • the present disclosure relates to a machine and a method for producing packaging inserts, and especially to an arrangement related to the components and method for forming the partition walls of the packaging insert.
  • US4894113 discloses a method of forming a wall in a packaging insert, wherein the distance between the wall to be formed and a previously formed wall is defined by the size of a first pressing device arranged between the previous wall and the location of the wall to be formed.
  • the height of the wall to be formed is defined by the size of a wall forming member around which the insert material is formed when a second pressing device is pressed towards the first pressing device with the wall to be formed in between.
  • the second pressing device is lifted to allow the previous wall to pass and the insert material and the previous wall are moved a distance being the size of the first pressing device plus the thickness of the wall forming member.
  • this is achieved by a method for producing a packaging insert by forming at least one partition wall from an insert material using a first pressing device and a second pressing device, the method comprising the steps of transporting the insert material along an axis A, holding the insert material in a fixed position by the second pressing device, moving the first pressing device along axis A to a distance D from the second pressing device corresponding to the double intended height of the partition wall, holding and moving the insert material by means of the first pressing device toward the second pressing device along axis A such that the insert material is pressed between the first and the second pressing device into an erect position forming a partition wall, after formation of a partition wall, lifting or moving the second pressing device as to allow the formed partition wall to pass the second pressing device, and moving the insert material and the formed partition wall along the axis A a distance selected as distance between the formed partition wall and a subsequent partition wall to be formed.
  • the method for producing a packaging insert may be performed using only one piece of insert material to produce packaging inserts of different sizes using only one machine and with a limited amount of production steps.
  • the first pressing device may take hold of the insert material by pressing and thereby push the insert material along axis A as it moves along this axis.
  • the second pressing device may be in a fixed position such that when the first pressing device moves the insert material toward the second pressing device, the insert material is pressed between the two pressing devices into an erect position.
  • the first pressing device When taking hold of the insert material, the first pressing device may be fully retracted from the second pressing device, at a distance D corresponding to the double intended height of the partition wall to be formed.

Lifting the second pressing device 3 allows the partition wall 5 to pass underneath as the insert material 6 is transported along the axis A by the gripping device 4, corresponding to step 102 of fig. 1 .
  • the axis B can be placed upstreams from the axis B illustrated in fig. 5 , i. e. on the part of the second pressing device that is closest to the first pressing device, to allow for a rotation in the opposite direction of R B as to save space and allow the gripping device to grasp a formed partition wall further upstreams.
  • the gripping device 4 is controlled by two linear motors 41, 42 where the first linear motor 41 controls the movement in the Y direction and the second linear motor 42 controls the movement in the X/X' directions.
  • the gripping device 4 is arranged to fix the position of the partition wall 5 to a bottom material 7. Further, it is arranged to seize a partition wall 5 and move the insert material 6 along the axis A in the X direction. The movement transports the insert material 6 along the axis A such that a distance between the most recently formed partition wall 5 and the planar surface 3a second pressing device 3 corresponds to the distance between two consecutive partition walls 5.
  • the gripping device 4 comprises two linear parts extending perpendicular to axis A, in parallel to the direction Y.
  • the gripping device 4 may be described as a parallel gripper.
  • fig. 5 shows the retraction along axis A in the X' direction of the first pressing device 2, as it retracts back to the open position (illustrated in fig. 2 ).
  • the bottom material 7 is fed from a paper tray 12, schematically shown in fig. 5 .
  • Fastening means such as glue or adhesive is applied on the side facing the insert material 6 by the gluing means 10.
  • the bottom material 7 and the insert material 6 are fastened to each other by the gripping device 4 pressing the formed partition wall 5 on the insert material 6 toward the bottom material 7.
  • the insert material 6 and the bottom material 7 can alternatively, or as complement, be fastened to each other by sewing or stapling or a combination of the presented alternatives.
  • sewing and/or stapling can be performed at ends of a packaging insert comprising one or more formed partition walls 5.
  • the gluing device 10 may be removed and replaced by a sewing or stapling device 9.
  • a cutting device 8, exemplified in fig. 6 is arranged downstream in relation to the pressing devices 2, 3 and the gripping device 4, and is configured to cut the insert material 6 with formed partition walls 5 into packaging inserts at desired lengths.
  • the cutting device 8 comprises a cutting arm 83 to which a blade 81 is mounted and two cutting tracks 82a, 82b.
  • the cutting device 8 extends along an axis C, around which the cutting arm 83 can perform a rotation Rc.
  • the blade 81 is also rotatable R K in the plane of axis C.
  • the cutting device 8 has two cutting positions 82a, 82b in order to facilitate cutting close to or on either side of a partition wall 5.
  • the cutting positions 82a, 82b are chosen by 180 degree rotation of the cutting arm 83 around axis C and the distance between them corresponds to the thickness of the cutting arm 83.
  • the cutting device 8 can be arranged with the cutting arm 83 extending in parallel with the extension plane of the insert material 6, or alternatively perpendicular to said extension plane.
  • the blade 81 may in one embodiment be arranged to cut the insert material 6 in an angle slightly less than 90 degrees. The blade 81 can thereby easier cut close to a partition wall without interfering with the partition wall.
  • Fig. 7 illustrates a further alternative cutting device 8' which comprises two blades 81a, 81b.
  • the two blades 81a, 81b are arranged on a pivoting arm 84 which is rotatable around the axis D.
  • the axis D extends in parallel with axis A.
  • the cutting device 8' is moveable along axis A to provide cutting at a desired location.
  • the blades 81a, 81b and the pivoting arm 84 are further moveable in a direction perpendicular to axis A so as to provide the cutting action onto the insert material 6.
  • the blades 81a, 81b are inclined relative to the insert material 6 and axis A, providing an angle slightly less than 90 degrees, for instance in the range 70-89 degrees. As seen in fig. 7 , the blades 81a, 81b are inclined such that one of the blades 81b provides an inclination in one direction, and the other blade 81a an inclination in the other direction when in contact with the insert material 6. This provides inclined blades enabling cutting action close to a partition wall 5 in either direction.
  • the pivoting action of the pivoting arm 84, thereby selecting blade 81a, 81b, may be controlled by a motor, or directly affected by the movement of the cutting device 8', such that movement in one direction across the insert material 6 provides cutting action by one blade 81a, and movement in the opposite direction across the insert material 6 provides cutting action by the other blade 81b.
  • the cutting device 8' may comprise corresponding cutting tracks 82a, 82b as the cutting device 8.
  • the stapling device 9 is arranged to staple the insert material 6 to the bottom material 7.
  • the staples can be positioned on the insert material 6 in proximity to the angle between the partition wall 5 and insert material 6.
  • the stapling device 9 can be replaced by a sewing device, configured to sew the two materials 6, 7 to each other.
  • Fig. 8 illustrates an embodiment of the device 11 for blowing or poking the insert material 6 in the form of a pushing unit 90.
  • the pushing unit 90 comprises a frame 92 configured to be arranged such that the insert material 6 extends through an opening 96 of the frame 92.
  • a blade 94 is arranged at a bottom section 93 of the frame 92 .
  • the blade 94 may comprise a knife with a sharp edge and/or teeth for perforating the insert material.
  • the pushing unit 90 further comprises a sub-frame 95 to which the blade 94 is attached.
  • the sub-frame 95 is configured to be moveable in the direction Y when the insert material 6 extends through the frame 92.
  • the blade 94 will thereby push the insert material 6 in the direction Y.
  • the pushing unit 90 is further moveable along axis A to be positioned at the half distance D.
  • the pushing unit 90 will facilitate the formation of a partition wall. If the blade 94 is sharp and/or provided with teeth, the folding of the insert material 6 to form a partition wall 5 is further facilitated.
  • a linear motor may be arranged to move the sub-frame 95 in the direction Y.
  • Another linear motor may be arranged to move the pushing unit 90 along axis A to the desired position.
