Definitions

  • the invention relates to a method according to the preamble of claim 1 and a device for performing the same according to the preamble of claim 13.
  • the initially open folding blank is inserted transversely into the packaging section running in the longitudinal direction of the packaged goods movement, so that its main folding lines run transversely to the longitudinal direction.
  • the folding blank experiences an abrupt deflection of movement when it engages with the packaged goods, which drastically limits the maximum processing speed.
  • a relative movement is required between the folded blank and the packaged goods after the first contact to complete alignment, which can result in problems with high-speed machines and sensitive packaged goods.
  • the main parts of the folded blank After aligning the folded blank with the packaged goods, the main parts of the folded blank have to be folded around the main folding lines, which at least partially requires accompanying folding aids and can place a considerable load on the packed goods, which also limits the maximum processing speed.
  • relatively large longitudinal distances between the individual folding blanks and groups of packaged goods are required in the packaging section, so that the main parts of the folding blank can be folded unhindered about the main folding lines running transversely to the longitudinal direction. All of these measures limit the maximum working capacity of a continuously running machine can also be converted to different packaging sizes only in a very complex manner.
  • the present invention is therefore based on the object of designing a method and a device of the type mentioned in such a way that, in high-performance operation, packaged goods can be packaged very quickly and gently in such wrapping packages. In addition, a relatively easy adaptability to different packaging sizes should be ensured.
  • the invention is based on the idea of feeding the folding blanks to the packaging line in such a way that the main folding lines run in the longitudinal direction of the packaging line.
  • the feed is also largely fluid, that is to say at a feed position essentially without deflection of the movement of the folded blank and without a speed difference to the packaged goods.
  • a method of the type mentioned is characterized by the features listed in the characterizing part of claim 1. Since the folded blank is only brought into engagement with the packaged goods in an aligned form after the movement component corresponds to the packaged goods speed, relative movements between these parts are completely avoided and gentle handling of the packaged goods is ensured even with an extremely fast operating process.
  • the side feed has the advantage of easy access. Since the folding blank is already pre-folded in an L shape when the packaged goods are first handled, the packaging section itself can be shorter. The folding over of the main parts of the folded blank to run in the longitudinal direction of the packaging line H auptfaltlinien is relatively simple and can be performed much gentler on the packaged goods even with fast operation.
  • the method according to the invention is also suitable for the high-performance range if relatively sensitive packaged goods are to be packaged.
  • L-shaped pre-formed folding blanks are removed from a stack by being gripped at their upright sections and then fed laterally.
  • This has the advantage that the folding blank does not have to be folded over during the feeding and thus there is a simple operating sequence in this regard.
  • it would of course also be possible to separate and feed unfolded folding blanks arranged vertically in a stack, which is compared to feeding from a stack of unfolded folds arranged horizontally blanks has the advantage of a smaller bulk in the Z ujan- tion.
  • the possibly pre-folded L-shaped folding blanks are pivoted about a vertical axis during feeding by about 90 ° to 180 °.
  • the movement component of the folding blank can be adapted particularly well to that of the packaging line by pivoting the folding blank into the feed position.
  • the folding blank can preferably be guided on a circular path, the tangent of which opens into the packaging section.
  • a device of the type mentioned which is used to carry out the method is also distinguished according to the invention by the features listed in the characterizing part of claim 13. Accordingly, the device has a vertical support for the packaged goods groups ending at or behind the feed position and a lower-lying vertical support for the bottoms of the folded blanks and the packaged goods groups located thereon, which begins before or at the feed position.
  • the conveyor for the folded blanks inserts them laterally so that they come to rest at the feed position under the respective packaged goods group and on the lower vertical support.
  • the packaged goods groups then move from the higher vertical support to the bottoms of the folded blanks supported on the underside, whereby these parts to be combined have the same movement component and are not exposed to any relative transverse displacement.
  • the stationary fold then ensures links for folding around the main folding lines and the moving folding links for folding over the front flaps, with stationary devices attaching closure means for closing the packaging.
  • Such a device is comparatively simple and enables gentle packaging in high-performance operation.
  • the laterally arranged conveyor ensures good access, that is to say practically unhindered loading with folding blanks.
  • the device used for further transport from the feed position should expediently have a speed corresponding to the speed of the upstream means, although it would also be possible in principle to have a somewhat higher speed. However, this would lead to an impact load on the packaged goods groups and folding blanks, so that exact speed synchronization is more favorable.
  • Such chain conveyors are easy to implement and can be configured to be centrally adjustable with regard to a size-changing change in their carrier distances.
  • an exact speed synchronization can be achieved without slipping of the individual parts, which is particularly important for high-performance operation.
  • the sliding tables of the vertical supports should preferably be at least partially designed with longitudinal guides in order to ensure precise alignment and guiding of the moving parts and dimensional stability of the still unwrapped wrapping, which is of great importance for high-performance operation.
  • the conveyor designed as a revolving chain conveyor should preferably be L-shaped folded Faltzu baine this will capture to vertical sections and engage in the feeding position, ER to the folding blank or over a certain distance in the longitudinal direction of the V pack to move range, before the transport thereof all the way from the chain conveyor for further transporting taken. If these two chain conveyors, like the one for feeding the packaged goods groups, have the same speed of movement in the longitudinal direction, this results in a completely uniform transport takeover in connection with an extremely gentle handling of the folded blank and the packaged goods.
  • the swivel angle for the folding blank can be changed in a range from 90 ° to 180 °.
  • the stack buffer for the L-shaped pre-folded folding blanks enables batch-wise delivery of horizontally flattened folding blanks with continuous removal of the L-shaped folding blanks from the intermediate storage, i.e. for continuous high-performance operation.
  • the device according to claim 23 has a central adjustability of all or individual elements that come into engagement with the folding blank, adaptable to the respective packaging size.
  • This is particularly simple for all stationary links, such as the folding links for the sections of the folding blank to be folded around main folding lines and the fixed glue heads.
  • a central adjustability of the moving parts on the chain conveyors is possible, for example, in that drivers are attached to different chains, the mutual relative assignment of which can be changed, so that the mutual distances are variable.
  • the device according to claim 25 has five stationary glue heads, namely one for the outside of the further long side and two each for the tabs on both long sides.
  • Such an arrangement ensures a sufficiently secure closure of the wrapping and also enables the glue heads to be adjusted in size.
  • the device has a straight-line packaging section 10, within which the packaged goods 14, in the present case upright bottles, move in the longitudinal direction 12.
  • the packaged goods 14 are first fed by means of a packaged goods conveyor 16, for example a conveyor belt, in order to then be separated and transported on by means of a device 18.
  • the device 18 is designed as a chain conveyor, which, with individual conveyor arms, detects 20 groups of packaged goods 23, each with twelve bottles in the present case, and moves it forward in the longitudinal direction on a vertical support 22 in the form of a sliding table provided with side guides.
  • the packaged goods are held on a side guide of the sliding table by means of a link (not shown), which in turn ends in the area of a feed position 24 for folding blanks.
  • the conveyor arms 20 move in the longitudinal direction 12 until they fill the respective group of packaged goods 23 have constantly pushed from the sliding table 22 onto a lower-side folding blank that is moving with the same speed component.
  • folding blanks 28 are first stacked.
  • S be ta- pel with a forklift or the like batch delivered.
  • These folding blanks 28 for a wrapping package closed on all sides have a bottom 30 with straps 32 on both sides, a long side 34 with straps 36 on both sides, a cover 38 with straps 40 on both sides, and a longitudinal flap 42, also referred to as an industrial flap, and a further long side 44 with straps 46 on both sides.
  • the folding blanks 28 are then transferred, depending on requirements, into a buffer store (not described in more detail), in which they are pre-folded and stacked in an L-shape.
  • a separator 50 ensures that the L-shaped folding blanks 48 are occasionally pushed out laterally, which in turn are guided to the feeding position 24 by means of a device 52 designed as a chain conveyor for feeding the folding blanks 48.
  • the chain conveyor has individual grippers 54, which grip the folding blank 48 at an upright, front-side section, namely according to FIGS. 1 and 3 at the loops 36 and 40, and pull it out of the stack.
  • the chain conveyor has three deflection wheels 56, 58, 60, which are arranged so that the grippers 54 pivot the folding blank 48 into the feed position 24 and from there move over a short distance in the longitudinal direction 12 at the speed of movement of the packaged goods groups 23 and then release.
  • the Folded blank 48 pivoted in the area of the feed position 24 so that its bottom 30 comes to lie exactly under the respective packaged goods group 23, namely below the vertical support 22 and above a vertical support 70, which is also to be explained and is also designed as a sliding table, on or in front of the Feed position 24 begins and extends in the longitudinal direction 12 to the end of the device.
  • the vertical support 70 belongs to a device 62, which also has a chain conveyor, for the further transport of the folding blanks 48 and groups of packaged goods 23 located thereon.
  • This device 62 has drivers 64 which are moved in the longitudinal direction and which are arranged at a mutually adjustable distance and can be pivoted about horizontal axes.
  • the drivers 64 of the chain conveyor located under the vertical support 70 reach through longitudinal slots 72 of the sliding table shown in FIG. 4 and come into a transport engagement according to FIG. 2 with the tabs 32 on the bottom 30 of the folding blank 48.
  • the front flap 32 of the bottom 30 is pivoted up slightly by one or two drivers 64 (see FIG.
  • the device 62 for further transport preferably has a guide wall 74 which is vertically attached on one side to the sliding table or the vertical support 70 and which guides the longitudinal side 34 of the folding blank 48 via slide rails 76.
  • the further longitudinal side 44 and the lid 38 of the folding blank 48 are folded over in succession or at the same time by means of stationary folding aids.
  • arm-shaped, adjustable folding members 78 and 82 are used, the relative position or shape of which changes in the longitudinal direction 12 of the packaging section 10 such that, due to their external engagement with the further longitudinal side 44 and the cover 38, these members move the folding blank 48 around the main folding lines swivel.
  • the folding members 78 and 82 are each assigned a stationary, but adjustable, and also arm-shaped counter bearing 80 and 84, which extends in the longitudinal direction 12 and which is overhung at its end pointing in this longitudinal direction.
  • the abutments 80, 84 mentioned lie on the inside of the folding blank 48 in such a way that the packaged goods are in front of one is protected against its load.
  • the counter bearings 80 and 84, which are mounted in a floating manner at one end, can then leave the tubular wrapped wrapping on the rear face thereof.
  • the further longitudinal side 44 After the further longitudinal side 44 has been folded over, it is glued in its upper region by means of a stationary, also adjustable glue head 86, so that the longitudinal flap 42 of the cover 38 is folded over by means of a fixed but adjustable folding member 88 and a fixed but adjustable counter bearing 90 the other long side 44 can be glued.
  • the folding member 88 and the counter bearing 90 are formed similarly to the folding members 78, 82 and counter bearing 80, 84.
  • the tabs 36 and 46 on both long sides are glued by means of pairs of mutually superposed, fixed, but adjustable glue heads 92.
  • the L ash 32 by the grippers 64 easily released so that it can again slightly open, so that the glue-coated flaps can be folded 36 and 46th
  • the pivotable carriers 64 again ensure that the flaps 32 of the base 30 are completely folded over similar to how the drivers 64 are pivotable about horizontal axes and come into engagement with the tabs 40.
  • a finished, all-round wrapping package 102 with a packaged product group 23 is created.
  • the size of this group can be easily changed with a suitable selection of a suitable folding blank by adjusting the members that come into engagement with the group and the folding blank accordingly , which is preferably done via a central adjustment.
  • the pivoting angle when feeding the folding blanks can be changed approximately in the range between 90 ° and 180 °.
  • the folded blank can be stacked in a completely vertically flattened form and then pre-folded in an L-shape during the feeding.
  • Another feeding option is that the folding blanks are fed to the feeding position 24 at an acute angle to the packaging section 10 of the feeding position 24 essentially without pivoting on a largely straight path in such a way that here too there is at least an extensive adjustment of the movement components.
  • the tabs can also be attached by clipping or the like instead of gluing.
