With the in the 3-13 illustrated device 10 For example, product blocks from groups of products wrapped in an inner blank can be packed in an outer blank.

This is explained below on the basis of special product groups, namely cigarette groups 11. These presently essentially cuboid cigarette groups 11 from in the present case three superimposed rows of cigarettes are in in itself in an inner blank 12 wrapped and surrounded by this. Together with this interior blank 12 make up the cigarette groups 11 a (substantially cuboid) product block or cigarette block 13 ,

The interior blank 12 is usually made of thin material, such as Stanniol. With the device 10 become the finished cigarette blocks 13 in a folding box 14 or Hinge lid pack packaged. This happens in a special way, as will be explained later.

Such a folding box 14 , see. 1 , has a box part 15 for receiving the cigarette blocks 13 and one on the box part 15 over a line joint 18 hinged lid 16 , Part of such a folding box 14 , namely the box part 15, is in this case further a so-called collar 17 ,

The folding box 14 is from a flat folding or packing blank 19 made of (thin) cardboard. This folding blank 19 forms by folding lines in a conventional manner individual areas or areas for a box front wall 20 the folding box 14, a box back wall 21 and inner box part side flaps 22a, 22b and outer box part side flaps 23 ,

The box part side lobes 22a . 22b . 23 form corresponding, double-layered box side walls 24 of the folding box 14 , These sidewalls 23 . 24 form the (upright) (longitudinal) narrow sides of the essentially cuboid folding box 14 ,

To form the lid 16 has the folding cut 19 via a lid front wall 25 and a lid end wall 26 , For the formation of lid sidewalls 27 over inner lid side flaps 28 and outer lid side flaps 29 ,

In continuation of the inner lid side lobes 28 lid lids extend 30a . 30b that with the lid side lobes 28 are connected and in the finished folding box 14 on the inside of the lid end wall 26 issue.

At the lid-corner lobes 30a . 30b each opposite or opposite side are on the inner box part side lobes 22a . 22b in continuation of the same floor corner lobes 31a . 31b arranged. These lie with the finished folded pack 14 at the box part bottom wall 32 at.

With the device according to the invention 10 , which forms part of a cigarette packaging machine known per se, becomes the folding blank 19 (at least partially) around the respective cigarette block 13 folded. The production of the cigarette blocks 13 takes place in another, not shown here part of the packaging machine in a conventional manner, so that will not be discussed further.

The individual folding steps, to which this is mainly the case in the present invention, are shown schematically in FIGS 2a-2c shown.

In the embodiment of the 3-13 the device 10 first described below are by means of a (in this case in an upright or vertical plane rotating) transfer conveyor 33 , in this case a rotary (cyclically) driven transfer turret, individual cigarette blocks 13 together with adjacent or resting collar cut 17 to a transfer station 34 promoted.

For this purpose, previously upstream at a collar station 35 of the transfer conveyor 33 one after the other collar trimmings 17 by means of a slide-in element 36 , in particular collar stamp, in on the circumference of the transfer conveyor 33 located bags 37 pushed in, in this case radially or from the radial direction coming (this can also be different).

At a downstream supply station for cigarette blocks 38 the transfer conveyor 33 are perpendicular to the conveying direction of the same, in the present case also radially (this can also be different) the cigarette blocks in the respective collar 17 already having, respective bag 37 promoted.

At the transfer station 34 then the handover of the unit from the cigarette block takes place 13 and (on or Aufliegendem) collar 17 in a prepared bag 39 a radially arranged opposite, in the same (in this case also upright or vertical) rotating or rotating (cyclically) driven folding turret 40 ,

The transfer conveyor 33 and the folding turret 40 are presently arranged in a common vertical plane in which they rotate together; but they can also be arranged or rotate in a horizontal plane.

The handover of the cigarette block 13 with collar 17 to the folding turret 40 takes place under entrainment and partial folding of the outer folding blank 19 , as will be described later. The part of the folding blank 19 surrounded cigarette block 13 is then in the connection of the folding turret 40 with collar 17 up to another extension station 41 promoted, on the way there are still further folding operations are performed, which will not be discussed here.

The partially or possibly already completely finished folding box 14 will be at the unloading station 41 through a pusher 42 for further handling in the packaging machine (further handling is known) pushed out in the radial direction.

What the supply of the individual, to take with you at the transfer station 34 prepared folding blanks 19 to the folding turret 40 are concerned, they are previously upstream of the transfer station 34 in each case individually (intermittently) at a feed station for folding blanks 43 one after the other, one bag each held there 39 the folding turret 40 conveyed. In the present case, this is done by means of a rectilinearly movable supply member 44 , For example by means of a punch member having suction means / suction openings, which are controlled acted upon by negative pressure.

The feeder 44 promotes the folding blanks 19 radially to the pockets 39 and put these on / on recording surfaces 64 on / on, located on radial outer sides of axially extending pocket walls 45 the respective bag 39 are located.

In the present embodiment, the axially extending pocket walls 45 bound together with a transverse to this extending pocket bottom 65 a (substantially cuboid) receiving space 46 the respective bag 39 for each receiving a cigarette block 13 (including folding cut 19 as well as collar 17 ).

The dimensions of the recording room 46 can be roughly the outer dimensions (width / length / depth) of a cigarette block 13 correspond.

The folding blanks 19 become so on the receiving surfaces 64 put on that in each case an inside box part side flap 22a . 22b on each one (with respect to the bottom of the pocket raised or radially further outwardly arranged) receiving surface 64 to come to rest.

The lid front wall 25 and the lid end wall 26 forming folding blank sections on the one hand and the chess section bottom wall 32 On the other hand, as well as the chess part front wall 20 forming portions project axially on both sides over the bag 39 time.

The folding blanks 19 be on the respective bag 39 or at the receiving surfaces 64 held or fixed by means of the receiving surfaces 64 associated holding means.

In the present case, these are in particular at the Aufnameflächen 64 ending or in this opening, with negative pressure from a vacuum source acted upon suction ports 47th

In addition, every bag has 39 present two pairs of the receiving surfaces 64 laterally limiting, radially opposite the receiving surfaces 64 outwardly projecting blank side holder 66, between which the respective folding blank 19 sits, and at a distance that is about the Width of the folding blank 19 corresponds, are arranged on the pocket walls 45.

The blank page holders 66 have holding surfaces 66a to make sure that the folding blank 19 is fixed in rotation or in the circumferential direction on both sides during the rotation of the folding turret.

The one with a folding blank 19 provided pockets 39 become by rotation of the folding turret 40 downstream to the transfer station 34 promoted.

Especially the axially over the bag 39 protruding, the lid front wall 25 and the lid end wall 26 bildend or the chess divide bottom wall 32 as well as the chess section front wall 20 forming Faltzuschnittabschnitte be during this rotational movement by two on the outer circumference of the folding turret 40 along a circular arc piece extending, axially spaced, parallel outer holder 48 out.

At the transfer station 34 is by means of a transfer device 49 each along a straight line conveyor 50 a cigarette block 13 with collar 17 taking along the folding blank 19 from the current in the area of the transfer station 34 located bag 37 of the transfer conveyor 33 in a likewise at the transfer station 34 arranged, the bag 37 immediately opposite bag 39 the folding turret 40 promoted. Details of the involved organs of the transfer facility 49 will be explained later.

As part of the handover - and this is particularly important - both the inner box part side lobes 22a . 22b as well as the lid and bottom corner lobes 30a . 30b respectively. 31a . 31b by means of a folding device 67 folded.

The folding device 67 includes on both sides of the conveyor line 50 one side flap folding member 51a, 51b, respectively. The sidelobes folding organs 51a . 51b are each movable (synchronously) driven and each have a movable folding part 53 ,

The two folding parts 53 the lateral lobe folding organs 51a . 51b are also opposite each other on both sides of the conveyor line 50 arranged.

The free ends of the folding parts 53 each have a substantially continuous, uninterrupted folding surface 63 on.

The width of the uninterrupted folding surfaces 63 is at least half, preferably at least 2/3 of the width of the narrow side of the cigarette block 13 , Ideally, the width corresponds approximately to the narrow side width.

Next is the width of the folding surface 63 at least 1/3, preferably at least half the depth of the cigarette block 13 provided receiving space 46 the pocket 39 the folding turret 40 ,

In the present case, this is compared to the Seitenlappenfaltorgan 51b upstream side flap folder 51a and in particular its folding part 53 formed so that a radially inwardly facing side of the folding part on the outer circumference of the folding turret 40 along a circular arc piece and can be guided along it, which adjoins the circular arc or to the circular arc piece along which the (stationary) outer holder 48 runs.

In this case, the folding part 53 along its associated circular arc piece back and forth, namely on the corresponding side of the conveyor line 50 on the conveyor line 50 be moved to and from this.

In an analogous manner along a further, similar circular arc on the outer circumference of the folding turret 40, but on the other side of the conveyor line 50 , The folding part 53 of the other, further downstream Seitenlappenfaltorgans runs 51b ,

Along the circular arc can correspondingly the folding part 53 of the side lobe folder 51b be moved back and forth, namely on its associated side of the conveyor line 50 on the conveyor line to or from this path.

The aforementioned training of Faltteile 53 leads, among other things, that the folding parts 53 on the section covered by them on the outer circumference of the folding turret 40 the function of the (stationary) outer holder 48 take over and according to the above, axially projecting areas of Faltzuschnitts 19 to lead.

The sidelobes folding organs 51a . 51b in the present case each have a rotating, for example by means of a servomotor driven transmission gear 52 on, that the respective folding part 53 drives and is designed such that the aforementioned movements are carried out along the respective circular arc pieces.

The sidelobes folding organs 51a . 51b and in particular their respective folding part 53 serve to the inner box part side lobes 22a . 22b together with the top and bottom corner tabs 30a . 30b respectively. 31a . 31b in a first folding step in the in 2 B shown way to fold about 90 °. In particular, such that the inner box part side tabs 22a, 22b respectively at their associated narrow side of the (cuboid) cigarette block 13 issue.

The folding device 67 also has separate Ecklappenfaltorgane driven independently of the Seitenlappenfaltorganen 51 a, 51 b driven 54a . 54b , These are used to fold the lid corner flaps 30a . 30b or floor corner tabs 31a . 31b by 90 ° relative to the box part side tabs of the in 2 B shown position in the in 2c shown position, so that the lid corner flaps 30a . 30b or floor corner tabs 31a . 31b on the end wall or the bottom wall of the cigarette block 13 to lie or lie there.

For this purpose, the Ecklappenfaltorgane have 54a . 54b each via a transmission gear 55, with the rotation of a shaft of a motor (servomotor) in pivotal movements of two Ecklappenfaltteilen 56 every corner flap folder 54a . 54b be transferred to the corner lobes 30a . 30b respectively. 31a . 31b fold accordingly.

The movements of the two Ecklappenfaltteile 56 every corner flap folder 54a . 54b be synchronous to both sides of the conveyor line 50 in parallel, correspondingly spaced planes, each also parallel (at a distance) to the plane of rotation of the folding turret 40 are arranged.

Another special feature concerns the transfer device 49 ,

The folding turret 40 is a first (not with this co-rotating) slide 57 assigned to the transfer device 49. This first slider 57 is in the region of the transfer station 34 along the conveyor line 50 movable back and forth.

He serves among other things, the folding blank 19 in the area of the transfer station 34 from the bag 39 the folding turret 40 towards an opposite with the cigarette block 13 and the collar 17 equipped bag, also located in the area of the transfer station 37 of the transfer conveyor 33 to move. For this purpose, it has a direction transverse to the conveying direction or conveying path 50 arranged conveyor part 59 with a corresponding slide surface, during the aforementioned conveying movement on the folding blank 19 is present, in the present case at the later back wall 21 the folding box 14 forming section of the blank 19 ,

The first slider 57 furthermore has retaining means 62 that the cut 19 to fix on this (can). In the present case, these are in turn suction openings, which can be acted upon by negative pressure of a vacuum source.

Next is for a later (counter) movement of the cigarette block 13 with collar 17 taking along the blank 19 in the direction of the corresponding bag 39 the folding turret 40 the transfer conveyor 33 in the area of the transfer station 34 a movably driven, along the conveyor line 50 movable back and forth (but not with the transfer conveyor 33 co-rotating) (second) slider 58 assigned to the transfer device 49, which in this case also transversely to the conveying path 50 extending conveyor part 60 having.

The conveyor part 60 has a slider surface, which during the conveying movement towards the bag 39 the folding turret 40 on the collar 17 and / or the cigarette block 13 is present. Concretely on the collar 17 and / or the side of the cigarette block 13 that later on the front wall 20 the folding box 14 is present (front side).

The slider 58 or its conveying part 60 Incidentally, at opposite ends has holding means or holding parts 61 , which are arranged at a distance from each other, which is approximately the longitudinal extent of the cigarette block 11 equivalent. The holding parts 61 serve to a bottom and a header folding of the inner blank 12 hold the cigarette block 11 during the conveying movement, so that they do not move apart or unfold.

The concrete process of handing over the cigarette block 13 taking along the folding blank and the collar 17 as well as the folding by means of folding device 67 is as follows:

In each case retracted to a starting position slider 57 . 58 will be the next bag 39 the folding turret 40 with overlying folding blank 19 by turning the folding turret 40 to the transfer station 34 rotates, cf. 9 ,

Parallel or synchronous to this is the next pocket 37 of the transfer conveyor 33 with cigarette block 13 and collar 17 also to the transfer station 34 rotates.

Once two bags 37 . 39 are directly opposite or aligned with each other or possibly already (briefly) before, the Seitenlappenfaltorgane 51a . 51b , in particular their respective folding parts 53 , in each case in opposite directions from the conveyor line 50 moved away in a first, retracted (pass) position, in which the clear distance between the free ends of the folding parts 53 or the respective folding surfaces 63 wider than the folding blank 19 (width folding blank 19 = Distance between the outer edges of the two inner box part side lobes 22a . 22b of the folding blank 19 ).

In this first position of the folding parts 53 becomes the first slider 57 with retracted slide 58 in the direction of the opposite pocket 37 of the transfer conveyor 33 moved, cf. 10 , He takes or his conveyor part 59 the folding cut 19 with and moves it to the one in the opposite pocket 37 located cigarette block 13th

Specifically, as in 2a shown the box part back wall 21 the folding box 14 forming area of the folding blank 19 pack-like at the back of the cigarette block 13 is present.

For a safe guidance of the blank 19 become the holding means 62 of the slider 57 subjected to negative pressure.

In the next step, cf. 11 , the folding parts become 53 the lateral lobe folding organs 51a . 51b each synchronously toward each other in the direction of the conveyor line 50 moved to a second position, namely a folding position.

The respective folding surfaces 63 the folding parts 53 extend in the fold position shown in substantially parallel, spaced-apart planes on both sides of the conveyor line 50 and limit or form as a result a folding channel. The aforementioned levels are perpendicular to the plane of rotation of the folding turret 40 ,

The distance between the two folding surfaces 63 from one another in the folded position corresponds approximately to the width of the receiving space in the present embodiment 46 the pocket 39 or the width of a cigarette block 13 , Or the width of the folding blank 19 reduced by the width of the box part side lobes 22a . 22b ,

In this folding position pushes the second slider 58 the cigarette block 13 including collar 17 as well as overlying or adjacent folding blank 19 towards the opposite pocket 39 of the conveyor 40 ,

Synchronously, the first slider moves 57 in the same direction, so that the cigarette block 13, the collar 17 and the folding blank 19 between the two slides 57, 58 and are guided by them together.

The inner box part side tabs 22a . 22b are doing along the of the folding parts 53 the lateral lobe folding organs 51a . 51b limited or formed folding channels out, whereby they are folded by about 90 ° and create the narrow sides of the cigarette block 13, see. also 11 ,

During this process, the separately driven Ecklappenfaltorgane already 54a . 54b each also synchronously from a first, retracted position, cf. 11 , transferred to a second position, wherein they in the context of the transfer, the corner tabs 30a, 30b and 31a, 31b in the in 2c Fold shown way, cf. above. This will put the corner lobes 30a . 30b . 31a . 31b to the respective bottom or head folding of the cigarette block 13 on, whereby a unfolding of the same is prevented.

After the cigarette block 13 with the collar 17 and the cut 19 was passed to the folding turret 40 and the corner lobes 30a . 30b . 31a . 31b folded by the Ecklappenfaltorgane 54a, 54b, the second slider 58 the transfer conveyor 33 retracted to its retracted position, cf. please refer 12 , At the same time, the lateral flap folding organs drive 51a . 51b or their folding parts 53 together or towards each other in a third (leadership) position and form in this together on the circumference of the folding turret 40 an outer guide or outer wall for the cigarette block 13 with the collar 17 ; in particular their respective radially inwardly facing, along the respective circular arc piece extending side of the respective folding part 53 , see. the comments above. This is how the cigarette block gets 13 with the collar 17 on the circumference of the folding turret 40 by the Seitenlappenfaltorgane 51a . 51b , in particular by their folding parts 53, supported and upon further rotation of the folding turret 40 guided on the circumference.

The 14-16 show a further embodiment of the present invention. Functionally identical components are provided with the same reference numerals, as in the embodiment of 3-13 ,

Significant difference to the embodiment according to the 3-13 is that the blanks 19 at the feed station for folding blanks 43 not on receiving surfaces on radial outer sides of the pocket walls 45 the folding turret 40 be applied or applied to this, but that this by means of a corresponding stamp in the recording room 46 the bags 39 be pressed in, so the back wall 21 of the folding blank 19 rests on the bottom of the bag and the inner box part side tabs 22a, 22b already prefolded upright on the insides of the respective upright pocket walls 45 ,

The cut 19 Holding means in the bag (suction openings for applying negative pressure) of the pockets 39 are correspondingly not arranged on the radial outer sides of the pocket walls 45, but on the respective pocket bottom of the respective pocket 39. Accordingly, in this embodiment, neither receiving surfaces 64 necessary still blank page holder 66 or holding surfaces 66a ,

Next can also on the between the feeding for folding blanks 43 and the transfer station 34 arranged outer holder 48 be waived.
