EP3299159B1 - Method and device for producing shoulder boxes - Google Patents

Description

The invention relates to (cigarette) packs of the cap box type, namely to their manufacture using a method according to the preamble of claim 1. Furthermore, a special device is used to implement the method.

Cap boxes usually consist of a base part, a cover part and a frame (also called "shoulder") which is fixed within the base part and runs around it and which bears against and protrudes from the base side walls such that the cover part encompasses the frame when the package is closed. Bottom part and cover part can be connected to each other by a hinge strip ( US 5,938,018 ). An outer wrap, in particular made of paper or the like, is predominantly used in practice for completely or partially encasing the base part and cover part.

The focus here is on merging the base part and the frame. The aim is to increase the production process and the device for implementing the same in terms of performance so that a sufficient number of packs can be produced in the unit of time.

A method with the features of claim 1 is used to achieve this object.

The device therefore works with several, in particular with three coordinated and synchronously running production lines, each of which produces a cap box. The design and mode of operation of a slide-in station, that is to say an assembly for bringing the base part and the frame together, are of importance. This is connected to the erected floor side walls after insertion into the base part, preferably by gluing. The units from the base part and frame then arrive in a merging station in which the cover part is placed on the base part. The partial packs are then fed to a wrapping station for attaching a preferably complete outer wrapper or an outer wrapper.

An innovative core of the present technology - preferably in connection with multi-lane production - is that the frames are fed to a frame unit in a flat, i.e. folded-up formation - with upright positioning. During the standstill phase of the frame, preferably in an erection level that is offset downward from the plane of the feed, the frame is brought into the square shape according to the package, preferably by movable (suction) organs that grip the frame by grasping (outside) two of them pull apart opposite frame sections, preferably in connection with a deformation reducing the outer dimensions. The frame prepared in this way is transferred by downward movement to the base part provided in a lower level.

A special feature is that the bottom part of the pack has side walls, that is to say bottom side walls which are not (directly) connected to one another in the area of the pack corners. Rather, the frame is provided on the outside with glue, in particular with a strip of glue running all around, which enables a permanent, dimensionally stable connection to the individual bottom side walls. The frame therefore creates the three-dimensional shape of the base part.

The cigarette pack of the cap box type to be produced consists of a bottom part 10 and a lid part 11. The bottom part 10 forms a bottom wall 12 and (upright) bottom side walls 13 on the one hand and 14 on the other hand. The bottom side walls (13, 14) are pivotally connected to the bottom wall (12). For completion, the floor side walls (13, 14) are erected and stabilized in this position.

In an analogous manner, the cover part 11 is designed with a cover wall 15 and cover side walls 16.

To complete the package, a shoulder or a frame 17 running around it is arranged in the base part 10. This consists of mutually opposite frame sections 18, 19. The closed frame 17 is inserted into the base part 10 and connected to the (erected) bottom side walls (13, 14) by gluing. These are then fixed in the packaged position. In the present case, the frame 17 is provided all around with glue or with a continuous glue strip 20, which establishes the connection with the inside of the bottom side walls 13, 14. The frame 17 is made preferably from an elongated, folded strip, the ends of which are connected to one another in the region of a frame corner by a tab 21.

To connect the bottom part 10 and the lid part 11, the unit consisting of the bottom part 10, the lid part 11 and the frame 17 is preferably completely surrounded by an external fold 22. This blank, which is made of paper or the like, is connected to the free outer sides of base part 10 and cover 11 by (full-surface) gluing.

A compact, high-performance manufacturing system is schematically shown in Fig. 3 shown. In a (first) processing station, namely a merging station 23, the base part 10 and frame 17 are provided, folded according to the package and connected to one another. The units 24 thus created from base part 10 and frame 17 are fed to a further processing station for stabilizing the connection between base part 10 and frame 17, in the present case a fixing turret 25, which in particular has the task of the (glue) connection between base wall 10 and frame 17 to stabilize. There follows a lid station 26 for feeding separately prepared lid parts 11 and for uniting them with the units 24.

The package, which in principle is completed, is then transferred to a wrapping unit 27 for attaching the outer wrap 22 to the packages. The unit 27 consists of organs for attaching the outer blanks 22 to the packs, in particular by placing them on the top wall 15 by means of transfer rollers 28. These are assigned to cut magazines 29 for the outer blanks 22 with separating members 30 and glue units 31 for applying glue to the blanks 22. The packs with the outer wrap 22 are then fed to a folding station 32, in which the outer wrap 22 is finished, so that a cap box in the embodiment according to FIG Fig. 2 arises. The finished packs are then transferred to drying units, in particular to drying turrets 33 and, after leaving them, are transported away on a packing line 34.

The production facility is designed such that the individual folding and working steps for several packs are carried out simultaneously in the range of several, preferably three, parallel production lines. The processing units, namely in particular folding and conveying members, are arranged in a corresponding number next to one another, and are driven coaxially and synchronously in the case of rotating members. Accordingly, there are several, in particular three packs with each work cycle completed. The material to be processed, namely bottom part 10, cover part 11 and frame 17, is preferably supplied in the same or the same number of cycles to the respective units in the axial or axially parallel conveying direction, that is to say transversely to the (three) production lines.

The union station 23 consists of two special units, namely a frame assembly 35 and a floor assembly 36. The frame assembly 35 serves to prepare the frames 17 and to transfer them to a ready-made floor part 10, in particular by moving the frame 17 downwards. The floor assembly 36 is used for preparation of floor parts 10.

The blanks for the base part 10 are removed from a base magazine 37 and - transversely to the direction of the production lines - conveyed to the base unit 36 by a base conveyor 38. The blanks of the bottom part 10 removed from the bottom magazine 37 by a removal member are (first) fed to a folding unit. This essentially consists of a folding shaft 39 and a stamp 40. By moving the stamp 40 downward, the blank (10) is pushed downward through the correspondingly designed folding shaft 39, the bottom side walls 13, 14 being erected. The floor part 10 thus prepared is placed on the floor conveyor 38, namely between suitably arranged drivers 41 of a belt conveyor. The drivers 41 stabilize the upright bottom side walls 13 pointing transversely to the conveying direction.

The pre-folded bottom parts 10 are taken over by the bottom conveyor 38 by a preferably identical transfer conveyor 42 and fed to the union station 23. The transfer conveyor 42 is arranged above the plane of action of the floor conveyor 38 and accordingly detects the floor parts 10 with a lower strand.

In the union station 23, the base parts 10 are transferred to a main conveyor 44, which is also designed as a belt conveyor and has drivers 41 arranged at exact intervals from one another. The main conveyor 44 extends in the direction of the production lines for the packs. In the present case, a corresponding number (three) of main conveyors 44 are arranged in parallel next to one another, each with the same number of matching and synchronously operating units.

The bottom part 10 is removed from the conveyor 42 in the merging station 23 and, in particular, is transferred to the main conveyor 44 by a downward movement. In the combination station 23, up and down movable stamps 45 are effective, which, with elongated pressure bars, grasp the bottom wall 12 of the bottom part 10 on both sides of the belt of the transfer conveyor 42 by downward movement, remove it by downward movement from the transfer conveyor 42 and transfer it to the main conveyor 44. The main conveyor 44 transports the prepared floor parts 10 into the area of the frame assembly 35.

The frames 17 are fed separately and independently of the base parts 10 of the union station 23 or the frame assembly 35. The movements are coordinated.

The closed frames 17 are folded, that is to say lying flat, by a frame conveyor, namely a frame belt 46, to the unit 35. The conveyor 46 preferably consists of a single belt which rotates in a horizontal plane with an upright belt position and correspondingly arranged drivers 47. These each convey a frame 17, which is likewise positioned in an upright plane, into the region of the unit 35. The conveyor 46 is a schematically shown gluing station 47 upstream, in the area of which glue is applied to the flat folded frames 17 on the outside, namely in particular the glue strip 20.

Part of the conveyor path for the (glued) frame 17 are fixed guide rails 48 on both sides of the movement path of the frame 17. The guide rails 48 are arranged or dimensioned such that they are located outside or above the area of the glue strips 20 ( Fig. 5 ).

The drive of the frame belt 46 is controlled in such a way that a frame 17 is kept ready in the area of the frame assembly 35 in a horizontal plane and aligned with a base part 10 in a plane offset downwards ( Fig. 5 ). The frame 17 rests on a movable (horizontal) base, in the present case on a (divided) table 49.

For further processing, the frame 17 is removed from the feed level ( Fig. 5 ) in a standing up level ( Fig. 6 ) moved or lowered. For this purpose, the base or table 49 is withdrawn. The frame 17 is moved out of the area of the frame belt 46, specifically by moving downwards by means of an up and down movement Pressure element 50, which has a fork-shaped head and engages the frame 17 at an upper, free edge. The pressure member 50 is preferably designed such that guide webs 51 are arranged on both sides of the elongated frame 17. The frame 17 is inserted into a position between the guide webs 51 during transport into the frame assembly 35 ( Fig. 7 ). The actual pressure element 50 is located above the guide webs 51.

In the raising level of frame 17 ( Fig. 6 ) the frame 17 rests on a support member, in the present case on a horizontal stop plate 52 which consists of two sections 53 arranged at a distance from one another. The frame 17 lies - in the flat folded position - with end regions on the sections 53 ( Fig. 7 ). After the (horizontal) erection, the frame 17 is in a push-off position above a passage opening 64 delimited by the sections 53 of the stop plate 52. This lies exactly above the prepared base part 10 ( 8, 9 ).

Shaping elements are effective in the deformation plane for the frame 17, which is defined here by the stop plate 52. To erect or unfold the frame 17 into the functional, three-dimensional structure, erection organs are effective which grasp and pull apart two opposing frame sections, in the present case the longer frame sections 18. These are each gripped on the outside by movable folding members and moved into a position by corresponding movement pulled apart from each other, whereby the frame 17 is moved into the square contour. These folding members are preferably suction heads 54 which engage the frame sections 18 on the outside thereof. The relevant sections 18 are held on the suction heads 54 by suction air. These are taken from a recording position ( Fig. 7 . Fig. 8 ) in a spaced end position ( Fig. 10 ) emotional. The frame 17 thereby receives its shape in accordance with the package.

Each suction head 54 is designed as an elongated, web-like suction member with a plurality of suction bores 55 lying next to one another in a row. These are connected to a vacuum source via connecting channels and connecting channels. The frame section 18 in question is grasped and held over a greater, preferably central, length by the suction head 54 formed in this way.

The suction heads 54 are connected - preferably as a web projecting on one side - to a holding and actuating member, in the present case to an upright support rod 56 is connected to a rotary drive (not shown). By rotating the upright support rod 56, the suction head 54 is pivoted, namely from a receiving position (dash-dotted in Fig. 10 ) in the stop or end position (also Fig. 10 ). The frame 17 is folded into the square position. The support rod 56 also contains a longitudinal connection bore for the suction bores 55. The suction heads 54 are accordingly first brought into a starting position (dash-dotted lines in FIG Fig. 8 . Fig. 10 ). Then, after the frame sections 18 have been gripped, the suction heads 54 are moved in opposite pivoting movements into the end position according to FIG Fig. 10 emotional.

When the frame 17 is erected into the shape in accordance with the package, the frame 17 is deformed such that the outer contours are smaller than the corresponding dimensions of the base part 10. The (deformed) frame 17 can thus be inserted into the base part 10 without constraint.

In the present case, the deformation consists in that the free frame sections 19 are deformed inwards, that is to say they receive an inwardly shaped arcuate structure ( Fig. 10 ). As a result, free end regions of the frame section 18, in particular outside the effective range of the suction heads 54, are simultaneously drawn inward, including the corners formed between the sections 18 and 19, with a corresponding reduction in the outer contour of the frame 17.

The aforementioned deformation is brought about by shaped pieces which are effective on the outside of the frame sections 19, in particular by (upright) stop bolts 57 on both (outer) sides of the frame 17 or the sections 19. The action of the stop bolts 57 is preferably such that that during the opening or folding movement of the frame 17 by the action of the suction heads 54, the frame sections 19 are pressed against the - inwardly displaced - stop bolts 57, so that according to FIG Fig. 10 the deformation takes place through the unfolding process.

The stop bolts 57 can be moved downwards with the frame 17 into a lower position for transferring the (deformed) frame 17 to the base part 10 ( Fig. 11 ). The stop bolts 57 then return to the starting position by moving upwards 8, 9 back, that is to say in the plane for folding a (subsequent) frame 17. The frame 17 set into the base part receives through the restoring forces in the material of the frame 17 have the final rectangular shape, bearing against the erected floor side walls 13, 14.

The stop bolts 57 are arranged on a common support that can be moved up and down, preferably on a frame-shaped lifting support 58. This is attached to a common lifting rod 59 below the movement path of the base part 10. The lifting support 58 preferably consists of two lateral, bracket-like support arms 60, each with a horizontal support leg 61, on the underside of which a (downward-directed) stop pin 57 is attached.

The downward movement of the frame 17, preferably in accordance with the contour Fig. 10 , is effected by the lifting support 58 - while maintaining the shape of the stop bolts 57. The frame 17 is moved downward to the end position within the base part 10 by the support legs 61 and / or the stop bolts 57 and / or the suction heads 54 ( Fig. 11 ). The frame 17 is now released. The suction heads 54 are vented and then return to the (upper) starting position. Furthermore, the lifting beam 58 with the stop bolts 57 is moved into the upper starting position ( 8, 9 . Fig. 12 ) moved back by corresponding upward movement of the lifting beam 58. The (deformed) frame 17 is released by the upward movement of the lifting beam or the stop bolt 57. Due to the existing material tension, this takes on the correct, in particular rectangular shape (dash-dotted representation in Fig. 13 ).

When the stop bolts 57 move upwards, it is ensured that the frame 17 is held in the position in the base part 10. For this purpose, movable stop pieces 62 are moved into a holding position, bearing against an upper, free edge of the frame 17 ( Fig. 13 ). The stop pieces 62 preferably come into effect in the area of the frame sections 18 after the suction heads 54 have been withdrawn from the holding position. The stop pieces 62 are preferably rotated (about a vertical axis) into the operative position in the area of the frame sections 18 ( Fig. 13 , solid lines) and can be moved out of this operative position (dash-dotted lines in Fig. 13 ). The rotary movement is effected by belt drive or by (toothed) belts 63, which are driven synchronously with the other movement sequences and cause a corresponding rotary movement of the stop pieces 62.

The units 24 formed in the frame assembly 35 from the base part 10 and the frame 17 can be completed in this area by pressing together the frame sections 18, 19 and the associated base side walls 13, 14. In the present exemplary embodiment, the bottom side walls 13, 14 are in an inclined position during this phase ( Fig. 11, Fig. 12 ). A wedge-shaped gap is formed between the frame sections 18, 19 on the one hand and the side walls 13, 14 on the other hand. A special design of the drivers 41 of the main conveyor 44 ensures that the base parts 10, but also the units 24 on the conveyor 44, are secured against lifting, specifically by means of a nose-shaped projection 65 on the free edges of the drivers 41. The somewhat obliquely directed one Projection 65 is suitable for supporting free edges of the (obliquely directed) bottom side walls 13, 14.

The units 24 are subsequently - after leaving the main conveyor 44 - completed by pressing the bottom side walls 13, 14 against the frame sections 18, 19, in particular in the fixing turret 25. <B> LIST OF REFERENCES: </ b> 10 the bottom part 41 takeaway 11 cover part 42 Transfer conveyor 12 bottom wall 44 main conveyor 13 Bottom side wall 45 stamp 14 Bottom side wall 46 Rahmengurt 15 cover wall 47 gluing station 16 Lid sidewall 48 guide rail 17 frame 49 table 18 frame section 50 pressure member 19 frame section 51 guide web 20 glue strips 52 stop plate 21 flap 53 Through opening 22 outer wrapper 54 suction head 23 union station 55 suction bore 24 unit 56 supporting rod 25 Fixierrevolver 57 stop pin 26 cover station 58 lifting beam 27 wrapping unit 59 lifting rod 28 transfer roller 60 Beam 29 blank magazine 61 supporting leg 30 separating element 62 stop piece 31 glue assembly 63 belt 32 folding station 64 Through opening 33 drying turret 65 head Start 34 packing sheet 35 frame assembly 36 floor unit 37 floor Magazine 38 floor conveyor 39 folding shaft 40 stamp
