Definitions

  • the present invention relates to a handling device for closing outer bottom flaps of an outer packaging with the features of independent claim 1.
  • the invention relates to the production of a carton outer packaging, in particular to the production of an RSC carton.
  • cardboard outer packaging can be understood to mean outer packaging that is produced from suitable cardboard blanks.
  • the RSC stands for "regular slotted carton", and it is the typical box construction with four flaps or bottom flaps at the bottom box opening and four flaps or top flaps at the top box opening.
  • the bottom flaps or top flaps with the shorter side length are referred to as the smaller flaps or flaps.
  • the bottom flaps or top flaps with the longer side length that create the box length are called the main flaps.
  • the main tabs meet in the middle, where they can be glued together with a plastic or water-activated tape, for example.
  • the carton blank is first folded into the box construction with the top and bottom box openings open, and an overlapping side flap is glued, forming a parallelepiped open on both sides. Then the smaller inner bottom flaps with the shorter side length are folded inwards until they are arranged essentially perpendicularly to the respectively connected side wall.
  • the outer surfaces of the correspondingly folded smaller inner bottom flaps are usually provided with an adhesive or the like. Now the larger outer bottom flaps or main flaps are folded in the direction of the smaller inner bottom flaps and pressed against them, so that the larger outer bottom flaps or main flaps stick to the smaller inner bottom flaps get connected. According to the devices known in the prior art, the larger outer bottom flaps of cartons are actually closed by means of pivotable flaps.
  • a flap is required for each larger outer bottom flap to be closed, with each flap being driven by its own pneumatic cylinder or another suitable drive.
  • each cylinder must be adjusted separately.
  • two flaps and two suitable drives are required to close the larger outer bottom flaps of each carton. If several boxes are to be processed at the same time, the number of flaps and drives required increases accordingly.
  • the patent specification DE 43 25 181 C2 describes a handling device in which at least for the two outer surfaces of an end face there is a folding device which has a pre-folding unit for each outer flap, which bends and pivots each outer flap around its fold line without bringing the outer flap to rest against the inner flaps; and a common closing unit, the actuation of which brings the two angled outer links into contact with the inner links.
  • a first step the outer flaps are only bent around their fold line and enclose an angle of about 20 to 30 degrees with the inner flaps, for example.
  • the outer link plates which have already been angled, are brought into contact with the inner link plates.
  • This movement component can be applied by a ram, which is adjusted essentially vertically to the plane of the inner straps.
  • the separation of the adjustment required for complete folding into two movement components which are aligned essentially orthogonally to one another enables short adjustment paths for each movement component.
  • the JP 2014 162216 A discloses a generic handling device for closing outer bottom flaps of an outer packaging, the handling device comprising a holding device for a mounted cardboard blank, an adhesive application device and a closing module with a closing unit with two horizontally movable slides for closing the outer bottom flaps.
  • the invention relates to a handling device that includes at least one holding device for a mounted cardboard blank.
  • a mounted carton blank is to be understood in particular as a pre-glued carton blank which, after being mounted, forms a box shape with two opposite openings, with the two openings being flanked by open bottom flaps or top flaps. Folding lines are formed between the bottom flaps or top flaps and the side walls of the carton blank, which enable the bottom flaps or top flaps to be folded over or folded in in a controlled manner. This is particularly preferably an RSC cardboard blank.
  • bottom flaps is not to be understood in particular as being restrictive in relation to the arrangement in the finished product.
  • a carton blank that is closed at the bottom and manufactured using the handling device described here can then be tilted by about 90° and loaded and closed from the side, so that the flaps referred to as bottom flaps within the present application are arranged laterally in the finished product.
  • At least one adhesive application device is provided with which, for example, glue or another suitable adhesive can be applied to the outsides of folded-in inner bottom flaps in order to glue them to the subsequently folded-in outer bottom flaps.
  • a suitable adhesive is applied with the adhesive application device in the area of the contact point or contact line of the two folded-in outer bottom flaps.
  • the two outer bottom flaps are connected to each other with an adhesive strip.
  • a closure module which comprises at least one closure unit, is provided for folding in the outer bottom flaps.
  • the closing unit includes two sliding elements designed to be movable relative to one another in a horizontal plane.
  • the sliding elements comprise spring-loaded support elements.
  • the holding device provides first holding devices for clampingly holding inner side surfaces of the mounted carton blank.
  • the first holding devices brace themselves between the insides of two opposing side walls of the mounted cardboard blank.
  • the holding device comprises at least one second holding device for folding in and/or holding the at least one inner bottom flap of the mounted carton blank.
  • suction devices such as suction cups, suction cups that can be subjected to a vacuum, or the like.
  • the carton blank is in particular pulled up over a connecting link, with the inner bottom flaps being folded in.
  • the second holding devices attach to the folded-in inner bottom flaps in order to hold the cardboard blank that has been pulled open.
  • the second holding devices suck on the - usually two - inner bottom flaps and pull them in the direction of the interior space formed between the side walls of the mounted carton blank, as a result of which the inner bottom flaps are folded in and held by 90° along the fold lines.
  • a method for closing outer bottom flaps of an outer packaging is disclosed.
  • the carton blanks are provided as pre-glued flat blanks in a magazine or similar and must first be drawn into the box shape that is open on both sides.
  • cardboard blanks that have already been mounted can also be provided for the method.
  • the mounted carton blank is gripped by the first and/or second holding means of the holding device described above, with the inner bottom flaps being folded in beforehand or simultaneously or directly thereafter along the fold lines by 90° towards the interior of the box shape.
  • an adhesive can be applied at least in regions to the outer side surfaces of the folded-in inner bottom flaps.
  • the carton blank prepared in this way is arranged between two sliding elements of a closing unit.
  • the mounted carton blank with the inner bottom flaps folded in is first arranged between two sliding elements of a closing unit and the outer bottom flaps are closed.
  • Adhesive application device the adhesive are applied to the outer side surfaces of the folded inner bottom flaps.
  • the prepared carton blank is arranged in particular between the two sliding elements of the closing unit in such a way that a floor level formed by the folded-in inner bottom flaps is located directly on or slightly above a support level formed by the upper side of the sliding elements.
  • the outer bottom flaps of the prepared carton blank can now be closed by folding them in by 90° along the respective fold line by moving the two sliding elements of the closing unit towards one another in a horizontal plane which is formed directly below the bottom plane of the outer packaging formed by the folded-in inner bottom flaps.
  • the two sliding elements are each moved towards one another at the same relative speed until they essentially abut one another.
  • no adhesive is applied to the outer side surfaces of the inner bottom flaps.
  • the folded-in outer bottom flaps are closed by means of an adhesive tape or the like along a contact line formed between the two folded-in outer bottom flaps.
  • the adhesive application device can now apply an adhesive tape or the like from below.
  • the sliding elements can be moved towards one another again and, if necessary, the carton blank can also be pressed from above against the preferably spring-loaded contact surface of the sliding elements by a downward movement of the holding device.
  • an embodiment of the method can provide a combination of adhesive application to the outer side surfaces of the inner bottom flaps and adhesive application to the folded-in outer bottom flaps.
  • the closure module comprises a plurality of closure units, each with two sliding elements designed to be movable relative to one another in a horizontal plane, so that a number of carton blanks that corresponds to the number of closing units can be processed simultaneously within the closing module.
  • the sliding elements of all closing units can be arranged in a common horizontal plane, so that the upper sides of all sliding elements lie in a common support plane.
  • At least the sliding elements of a closing unit are arranged in a motion-coupled manner on a common drive mechanism in such a way that, at the same time as the first sliding element of the closing unit moves in a first direction, a counter-movement of the second sliding element of the closing unit takes place in the opposite direction. so that the sliding elements of a closing unit move either towards or away from each other at the same relative speed. Due to the coupled movement of the two sliding elements, the two outer bottom flaps of a carton blank are folded over or folded in at the same time, with only a single drive being necessary.
  • the sliding elements of all closure units - as described above - are arranged in a motion-coupled manner on a common drive mechanism, so that only a single drive is required for the simultaneous processing of several carton blanks, which means that the closure module can be manufactured cost-effectively .
  • the drive mechanism can comprise at least one circulating conveyor arranged on a drive means with an upper run and a lower run, with one of the sliding elements of a closing unit being arranged on the upper run of the conveyor and the other sliding element of the closing unit being arranged on the lower run of the conveyor. Since the direction of movement of the lower run is opposite to the direction of movement of the upper run in a circulating conveyor, the arrangement of the sliding elements described causes the sliding element of a sealing unit arranged on the upper run to move in the opposite direction to the sliding element of the sealing unit arranged on the lower run.
  • the drive mechanism can preferably comprise two conveying means guided in parallel and arranged on the drive means via a common drive shaft.
  • the sliding elements are each arranged between the two funding means and each attached to the two funding means.
  • the sliding elements are particularly preferably arranged alternately on both sides on the upper strand of both conveyors or on both sides of the lower strand of both conveyors.
  • An electric motor, a servo drive or the like is provided as the drive means for the conveying means.
  • the at least one preferably circulating conveying means is a toothed belt, for example.
  • a large number of sliding elements and thus a large number of closing units can be operated via a single servo drive or another suitable drive means.
  • Such a central drive allows in particular a simplified, synchronous start-up of the handling device.
  • the capping speed of a plurality of capping units can be easily adapted to a new product, in particular a new RSC. Cardboard cutting, to be customized.
  • the sliding elements can be positioned at different points on the circulating conveyor.
  • the sliding elements of all closing units can also each have their own drive, with the drives being controlled via a control device in such a way that the sliding elements of a closing unit can each be moved in opposite directions and/or that adjacent sliding elements of adjacent closing units can be moved in opposite directions.
  • the sliding elements have spring-loaded support elements that form the support surface for the outer bottom flaps of the outer packaging.
  • a uniform force distribution is achieved by the springing of a large number of support elements, which in particular enables excess adhesive, for example glue, to be pressed out uniformly between the inner and outer bottom flaps.
  • the excess glue can be removed in particular via a removal device.
  • Each closing unit is preferably assigned a removal device, for example a glue suction device or the like.
  • a transport device for transporting away carton blanks that are closed at the bottom can also be arranged below the at least one closing unit.
  • the carton blanks, which are closed at the bottom can be set down on the transport device by moving the sliding elements of the respective closing unit in a direction away from each other.
  • guide elements can be provided for the controlled setting down of the carton blanks, which are closed at the bottom, on the transport device.
  • first guide elements can be formed below the sliding elements and further second guide elements can be provided on the sliding elements.
  • the first guide elements are designed, for example, as oblique guide plates parallel to the transport device and largely orthogonal to the sliding elements of the closing unit(s). The inclined guide plates reduce the impact energy of the carton blanks, which are closed at the bottom, on the transport device, which means that the carton blanks can be prevented from falling over.
  • the arrangement of a transport device that feeds the carton blanks, which are closed on the bottom side, for further processing below the at least one closing unit is particularly space-saving. While the carton blank closed on the bottom side is thrown onto the transport device, the holding device can already grip the next mounted carton blank and prepare it for the closing of the outer bottom flaps by retracting the inner bottom flaps. As a result, the throughput of processed carton blanks can be increased, since the holding device does not have to move the carton blank, which is closed on the bottom side, to a transport device and deposit it there.
  • the carton blanks, which are closed at the bottom can also only be dropped in certain processing schemes. For other processes, it can make sense to move the carton blanks, which are closed at the bottom, to another conveyor for further processing with the holding tool or holding device.
  • the holding device holding the carton blank performs a slight downward movement in the direction of the spring-loaded support surface of the sliding elements that are placed one on top of the other.
  • the 1 shows a schematic of a process sequence 1 for producing an outer packaging 120 open on one side, in particular an RSC outer packaging.

  • a third method step Vc in the embodiment of the method shown here, an adhesive 130 is applied at least in regions to the outsides of the folded-in inner bottom flaps 103.
  • a fourth method step Vd the outer bottom flaps 104 are folded in using a closure module 10, which is described in detail below, and the Outer packaging 120 formed in this way, which is open on one side, is fed to further processing via a transport device 16 assigned to the closure module 10 .

  • the outer packaging is fed to a packaging module, for example, in which the outer packaging is filled with items and, if necessary, sealed.
  • the outer packaging which is closed on the bottom by the infeed movement of the pressure strips 20a, 20b of a pair of slides 25, can be released by moving the pressure strips 20a, 20b of the pair of slides 25 away from one another and can be set down on the transport device 16 arranged below the adjustment mechanism 11.
  • First guide elements 17 , 18 can be provided on the substructure 12 so that the outer packaging does not tip over or twist when it is placed on the transport device 16 .
  • second guide elements 24 can be arranged to support the pressure strips 20a, 20b.
  • the outer packaging is guided on the transport unit 16 by lateral guide elements 18 .
  • the first guide elements 17 arranged above the lateral guide elements 18 are designed in particular as an inclined surface in order to advantageously reduce the impact energy of the outer packaging on the transport device 16 and thereby prevent the outer packaging from falling over.
  • the entire process flow, in particular the further transport of the outer packaging to the subsequent packaging modules, can be optimized in terms of time by directly depositing the outer packaging, which is closed on the bottom side.
  • a closure module 10 For folding the outer bottom flaps 104 of a carton blank 101 by an infeed movement of two sliding elements or pressure bars 20a, 20b, a closure module 10 can also be used without a substructure 12 according to FIG 10 be used.
  • a closure module 10 has a base 12 according to FIG Figures 9 and 10 up
  • the outer packaging which is closed on the bottom side
  • the bottom side The closed outer packaging can be brought into a desired orientation by rotating the gripping device 50, for example the outer packaging can be rotated by 90°.
  • the bottom-closed outer packaging is set down on a transport device 16 of the lower part 12 of a closure module 10, it can also be provided that, after the outer bottom flaps 104 have been closed and pressed on, the bottom-closed outer packaging is first rotated, in particular a 90° rotation, before the Outer packaging is deposited onto the transport device 16 by a movement of the pressure strips 20a, 20b of the pair of slides 25 directed away from one another.
  • This rotation can also be brought about in particular by a rotation of the gripping device 50 holding the outer packaging during the entire folding and closing process.
  • the bottom-sealed outer packaging can now be filled directly with articles, for example bottles, with an outer packaging combined article combinations, for example baskets, trays, shrink packs, multipacks, filled with bottles or the like in a downstream packaging module. Provision can also be made for dividing elements, for example compartments, to be inserted into the outer packaging first, and then for the articles to be filled.
  • a large number of outer packages can be processed at the same time with the aid of a single drive.
  • the number of outer packages that can be closed in parallel corresponds to the number of slide pairs 25 that are coupled to one another in terms of drive technology. Since only one drive has to be controlled, such a closure module 10 can be put into operation easily. In particular, such a closure module 10 can be quickly and easily adapted to a new product when there is a product change. For example, the respective speed and the respective time interval at which the toothed belts 31, 32 are driven must be set via the control device in order to set the appropriate spacing of the pressure strips 20a, 20b of the pairs of slides 25 before the outer bottom flaps 104 of the outer packaging 101 are closed.
  • the necessary spacing results from a width of the outer packaging 101 to be arranged between the pressure strips 20a, 20b of the respective pair of slides 25.
  • the closing speed can be adapted to the respective outer packaging 101.
