Definitions

  • the present invention relates to a method and device for assembling industrial packaging.
  • packaging boxes with eight side wall panels are used.
  • these packaging boxes have an octagonal shape.
  • the octagonal packaging boxes, also referred to as "octabins" are supplied in a folded, flat position and can therefore be stored without taking up much space.
  • the packaging boxes When the packaging boxes have to be used, they are unfolded and provided with one or more bases, for instance a base on the underside and a base (lid) on the top side.
  • the octagonal shape of the packaging box provides optimization of the available space when the octagonal box is transported on a pallet in combination with a rigid construction, so that the products remain well protected.
  • the packaging boxes are generally constructed from a package sleeve and one or two separate bases which can be arranged in unfolded position on the package sleeve.
  • Embodiments are however also known (such as, among others, the so-called "ready for use” octabin of applicant) in which the package sleeve is provided with a base which folds out simultaneously with unfolding of the package sleeve.
  • assembly machines which are built up of a number of sections, wherein each section performs one or more predetermined operations.
  • the package sleeves are for instance supplied, in a second section the package sleeves are unfolded to some extent, in a third section the packaging is unfolded further, in a subsequent section the package sleeve is tilted, and so on.
  • Such known assembly machines have large dimensions (length and width of several tens of metres) and are expensive.
  • a further drawback of the known assembly machines is that the package sleeves are subjected to relatively great forces and shocks during the assembly, which adversely affects the quality of the packaging.
  • the known assembly machines are suitable for one determined type of packaging box.
  • other assembly machines must be used, or the existing machines must be considerably modified.
  • An object of the present invention is to provide a device and method in which the above stated drawbacks are obviated.
  • this object is achieved in a device for assembling industrial packaging which in use has a polygonal cross-section, comprising:
  • the supply means, unfolding means and discharge means are herein combined to form a single, articulated (robot) arm and stationary receiving element.
  • the robot arm is provided with a gripper element with which the package sleeve can be picked up, tilted and placed on a receiving unit.
  • the package sleeve can be unfolded in co-action with a second gripper element provided on the receiving unit.
  • the same arm with gripper unit is then used to carry the unfolded package sleeve to a desired position in the collection area, where further operations can take place. Practically the whole assembly of the package sleeve can therefore be performed with a minimum number of components, thus enabling an extremely compact and low-maintenance setup.
  • the area occupied by the device (assembly area), as well as the storage area (area in which the package sleeves and bases are stored and the pallets are optionally collected) and the collection area to which the assembled packages and optionally the pallets are taken, need only cover an area of ten by ten metres or less. Because the device further exerts as many natural movements as possible on the package sleeve, there are (practically) no physical impacts on the packages.
  • the device comprises base arranging means for arranging at least one base part in the unfolded package sleeve.
  • base arranging means can be provided as an additional unit, but in a further embodiment the base arranging means are formed by the above stated arm, wherein the control means are adapted to displace the first gripper unit to a supply of base parts, to grip a base part, to displace a base part to the unfolded package sleeve and to slide the base part into the unfolded package sleeve.
  • the assembly construction can be further simplified by making use of the components already applied for assembly of the package sleeve.
  • the first and/or second gripper unit are provided with one or more suction mouths with which a package sleeve can be suctioned fixedly onto the arm or the receiving element. This manner of gripping the package sleeve, and optionally a package base, prevents the surface thereof being damaged.
  • the first gripper unit is also provided with engaging means for engaging a pallet. It is hereby possible, with the same arm with which the package sleeves are picked up, to also displace the associated pallet from the storage area to the correct collection area.
  • the arm, and in particular the first gripper unit thereof can be displaced to a supply of pallets, wherein the gripper unit engages and then displaces the pallet to the collection area.
  • the pallet is then ready for placing of an assembled packaging thereon.
  • the receiving unit is provided with an aligning provision for placing in the correct lateral position a package sleeve placed on the receiving unit.
  • the receiving unit is preferably provided with a number of, preferably four or more, pivot arms which are displaceable between a position releasing the package sleeve and a position resting against the inside of the unfolded package sleeve when it is placed on the receiving unit, for the purpose of placing the package sleeve in the correct unfolded position, for instance when the first gripper unit is released from the package sleeve in order to pick up for instance a base part.
  • package sleeves are known which are already provided beforehand with an fold-out base.
  • the base When the package sleeve is unfolded by the first and second gripper unit, the base automatically comes to lie in a more or less flat position.
  • the receiving unit is provided according to a preferred embodiment with a third gripper unit, preferably provided with one or more suction mouths, for the purpose of gripping the base and displacing the base to the correct, unfolded position. This ensures that, in such a packaging provided with an fold-out base, the base is always placed in the correct position after assembly.
  • a method for assembling industrial packaging which in use has a polygonal cross-section, comprising of:
  • the package sleeve is further embodied such that a polygon is defined in an unfolded position, wherein the number of corners equals eight, which results in an octagonal box.
  • the number of corners can however also be a multiple of eight.
  • the packaging is preferably manufactured from corrugated board with a thickness between five and twenty-five millimetres, preferably between ten and fifteen millimetres. Such a material in combination with said material thickness provides a sufficiently strong construction, which can furthermore be readily processed and can be recycled after use.
  • the height of the box typically varies between one and two metres, and the volume thereof varies between two and three thousand litres.
  • the assembly device 1 shown in figure 1 is constructed from a robot arm 2 and a separate receiving unit 10.
  • Robot arm 2 comprises a foot 4 arranged on a ground surface and consisting of a lower part 4' and an upper part 4" rotatable relative thereto.
  • An articulated arm 5,5' is arranged on foot 4.
  • Arm 5,5' can be displaced up and downward in known manner by the drive means (not shown).
  • Rotatable part 4" of the foot can likewise be rotated with drive means (not shown) so that the arm can rotate relative to the ground surface.
  • Other embodiments of a robot arm can also be envisaged.
  • Gripper unit 7 is herein mounted on arm 5' such that using drive means (not shown) the gripper unit is rotatable relative to the arm (P 1 ) and also pivotable relative to arm 5' (P 2 ).
  • Robot arm 2 is connected to a remotely placed control unit 25 with which the different components of robot arm 2 can be controlled. Owing to this embodiment of robot arm 2 the gripper unit can be guided under the influence of control unit 25 to any desired position within a predetermined radius from foot 4 in order to lift and displace a random object.
  • Gripper unit 7 is provided on the underside with a number of suction cups 8 connected to a compressor (not shown).
  • the compressor can provide an underpressure such that an object is suctioned fixedly onto gripper unit 7.
  • suction cups 8 the object can be fixed to gripper unit 7 without the surface of the object herein being damaged, which enhances the quality of the packaging product.
  • the suction cups are used to pick up relatively light objects in the form of a package sleeve and/or a package base.
  • gripper unit 7 is provided with four gripping arms 9 (two of which are shown in figure 1). These gripping arms 9 take a pivotable form so that these can engage a pallet two by two.
  • Assembly device 1 further comprises a receiving unit 10 which is constructed from a frame 13 on which a lying part 14 and a standing part 15 are arranged.
  • a receiving unit 10 which is constructed from a frame 13 on which a lying part 14 and a standing part 15 are arranged.
  • an endless conveyor belt 17 on which a package sleeve can be placed.
  • a rod 18 which extends transversely thereof and which functions as a stop for a package sleeve arranged on conveyor belt 17.
  • Also provided in standing part 15 is a number of suction cups 16 which are connected to a generator (not shown) in similar manner as the above stated suction cups 8.
  • suction cups 16 can suction a package sleeve fixedly to the standing part 15 of receiving unit 10.
  • suction cup 20 with which a base of a special packaging, provided with a base, can optionally be fixed in a correct position.
  • suction cup 20 can be omitted.
  • Two retaining members 21 are finally shown.
  • Four or more retaining members will in practice be provided on lying part 14.
  • Retaining members 21 are embodied so as to be pivotable relative to lying part 14. In the starting position (full line) the retaining members extend substantially horizontally, while in the retaining position (broken lines) the retaining members are rotated upward into a vertical position. In this position they can hold a folded-open package sleeve in the opened position, as further set forth below.
  • FIG 1 further shows that receiving unit 10 is connected to the above mentioned control unit 25 with which the different components of the receiving unit can be controlled together with the components of robot arm 2.
  • Figures 2a to 21 show the embodiment of figure 1 in the different stages of the assembly of the packaging.
  • Figure 2a shows the initial stage in which arm 5 of robot arm 2 is displaced to a pallet supply.
  • the pallet gripping arms 9 have pivoted outward so as to be able to engage two mutually opposite edges of the upper pallet (p).
  • the pallet is thus engaged, lifted and displaced by rotation of robot arm 2 in order to set down the pallet at a different position, also referred to as collecting position (figure 2b).
  • collecting position (figure 2b).
  • arms 9 are pivoted inward once again, as shown clearly in figure 2b.
  • Gripper unit 7 of robot arm 2 is then moved to a supply of package sleeves (h) (figure 2c).
  • the gripper unit is pressed against uppermost sleeve h, whereafter suction mouths 8 suction the relevant sleeve fixedly to gripper unit 7.
  • the arm then lifts the fixedly suctioned package sleeve h, tilts it to a vertical position (figure 2d) and places it on receiving unit 10 (figure 2e).
  • the gripper unit places package sleeve h on endless belt 17 and releases the package sleeve. In this situation the package sleeve is enclosed between suction cups 8 of gripper unit 7 and suction cups 16 of receiving unit 10, but the intermediate distance is such that the package sleeve is free to move in lateral direction.
  • Endless belt 17 is driven (in direction P 3 ) and displaces the package sleeve in lateral direction until at a given moment it comes to lie against stop 18. The package sleeve is thus correctly aligned relative to receiving unit 10.
  • suction mouths 8 After suction mouths 8 have once again gripped package sleeves h, gripper unit 7 presses the packaging unit tightly against suction mouths 16 provided in the standing part 15 of receiving unit 10. Suction mouths 16 are then activated so that the package sleeve is held fast on two sides by the suction cups. On the left-hand side (in figure 1) the sleeve is held fast by suction mouths 8 of gripper unit 7, while on the right-hand side the sleeve is held fast by suction mouths 16 of receiving unit 10 (figure 2f).
  • FIG. 2g shows the final position, in which the package sleeve is fully unfolded and the packaging has therefore obtained a form of octagonal cross-section.
  • the above mentioned retaining members 21 are pivoted upward under the control of control unit 25 until they come to lie against the inner side of the walls of the package sleeve.
  • gripper unit 7 releases package sleeve h, it remains in the octagonal form as a result of retaining members 21.
  • Gripper unit 7 is then displaced to a supply of bases in the storage area and grips the uppermost base b by means of suction cups 8.
  • the gripper unit displaces the base to a position above the package sleeve (compare figure 21) and subsequently pushes the base downward so that the base is displaced into the packaging from above.
  • additional means with which the base can be placed at the correct position in the package sleeve for instance in the form of a pusher which protrudes into the package sleeve at the top and which pushes the base downward further until it has reached roughly the bottom end of package sleeve h.
  • retaining members 21 are no longer necessary to hold the package sleeve in the octagonal form. Retaining members 21 are therefore pivoted downward until they extend horizontally.
  • gripper unit 7 once more grips the package sleeve provided with a base (compare figure 2j) and displaces it to the collection area where the previously placed pallet (p) is waiting, as shown in figure 2k.
  • Gripper unit 7 places the package sleeve provided with a base on the pallet and releases itself from the sleeve in order to begin a subsequent cycle (figure 21). The combination of pallet and packaging is now ready to be transported to the filling space where the packaging can be filled with products.
  • a base is arranged beforehand in some embodiments of the package sleeve. In this embodiment of the packaging the steps of picking up and arranging the separate base in the package sleeve are therefore unnecessary. The base will also automatically unfold after unfolding of a package sleeve.
  • a number of extra suction mouths 20 are provided. These suction mouths are suctioned fixedly to the base of the packaging and displace it until the base is located in the correct position.
