In the drawings, a preferred application is shown, namely the manufacture of packages of the type folding carton for cigarettes. This type of package consists of box part 11 and lid 12. The box part 11 has a box front wall 13 and a box rear wall 14, which are connected to each other via a bottom wall 15. The lid 12 includes a lid front wall 16, a lid rear wall 17, and a lid end wall 18 therebetween.

Side walls of the pack, namely the box part 11 on the one hand and the lid 12 on the other hand, each consist of two completely or partially overlapping folding flaps. On the box front wall 13 are laterally outboard box side flaps 19 and on the box rear wall 14 are lateral inside box side flaps 20 are attached. Correspondingly, in the region of the lid 12 on the lid front wall 16, outer lid side tabs 21 and inner lid side tabs 22 are attached to the box rear wall. The blank is folded so that the associated side tabs 19 and 20 on the one hand and 21 and 22 on the other cover each other and are connected by glue together to form the side walls. Furthermore, in the present case, a collar 82 is arranged in the package 10.

The schematic in Fig. 4 illustrated device as part of a packaging machine for producing cigarette packs of the type folding box consists of a folding turret 23, a subsequent (straight) transport path 24 and a transfer turret 25th

Contents of the pack 10 is a cigarette block 26 in the form of a cigarette group wrapped in an inner blank. The cigarette block 26 is enveloped in the area of the folding turret 23 in a blank for the pack 10. The largely finished pack 10 is ejected in the radial direction from pockets of the folding turret 23 and transferred to the transport path 24.

Upon entry of the packs 10 in the transport path 24 of the folding process for the blank is largely completed, except for the outer side tabs 19, 21. These extend like a wing in an upper, horizontal plane with upward facing box front wall 13 and lid front wall 16. The inner side lobes 20 and 21 are already folded into an upright plane to rest on the contents of the package, ie the cigarette block 26th

In the region of the transport path 24, the packs 10 are transported at a distance from each other by an endless conveyor. This is designed as a belt conveyor 27, as a toothed belt. On the free side drivers 28 are arranged, each detecting and transporting a pack 10 in the region of the rear bottom wall 15. The packs 10 lie with their longitudinal extent pointing in the conveying direction on the belt conveyor 27 and / or on a longitudinal direction of the transport path 24 extending guide profile 29.

Also at the top of the pack 10 24 guide and support members are provided in the region of the transport path. The laterally directed folding tabs, namely box side tabs 19 and lid side tabs 21, rest on legs 30 of the guide profile 29. Furthermore, guide rails 31 extending in the conveying direction are arranged on the upper side of the packs 10 and hold the packs 10 in the exact position on or in the conveying track 24.

The packages 10 are preferably transported continuously along the transport path 24. In this case, folding flaps are provided with glue, in the present case, the upright inner box side flaps 20 and lid side flaps 22. Thereafter, the package 10 is ready folded, namely by folding the box side flaps 19 and lid side tabs 21 until it rests against the associated side tabs 20, 22. The now finished package 10 is transferred to the forming unit, namely to the transfer turret 25th

In the area of the transport path 24 several glue stations are set up. The device is adapted to transfer two different types of glue to the package 10, namely cold glue on the one hand and hot melt (hotmelt) on the other. A first glue station 32 is used to transfer hot glue. A second sizing station 33 following in the conveying direction is set up for the transfer of cold glue.

In the present exemplary embodiment, the first glue station 32 has two glue units 34, 35 on both sides of the transport path 24. The glue units 34, 35 have glue nozzles 36 for transferring glue dots 37 onto the package 10. A special feature is that the glue portions are dispensed in a horizontal direction and transferred to an upright folding flap 20, 22.

The second glue station 33 in the present case also consists of two glue units 40, 41 on both sides of the transport path 24 for the transfer of individual glue spots 42 of another type of glue, namely cold glue. The glue units 40, 4 of the second glue station 33 are designed or arranged such that two superimposed rows of dots 38, 39 of the glue are produced. As compared to the FIGS. 2 and 3 it can be seen that in packs 10 with a smaller number of layers of cigarettes in the cigarette block 26, only one row of dots 38 is attached by appropriate control of the glue units 40, 41.

The glue points 42 of the first glue station 32 are mounted in a lower plane relative to the transport path 24. In particular, the glue spots 42 of hotmelt are applied between glue points 37 of the point row 38, ie adjacent to a free edge for connection to the side flaps 20, 22 certain outer side lobes 19,21.

The glue points 37, 42 can during the stoppage of the packs 10 by the appropriately trained glue units 34, 35; 40, 41 are transmitted. in the In the present case, the glue spots 37, 42, however, by the glue units 34, 35; 40, 41 transferred during the movement of the packs 10 on the side lobes 20, 22.

Subsequent to the glue station 33, the packs 10 reach the region of a folding station with folding members, which in the present case are designed as folding switches 43 on both sides of the conveying track 24. The shaped, rail-like Faltweichen 43 cause the side tabs 19, 21 are folded down during transport to the complete abutment against the side flaps 20, 22. The finished package 10 is conveyed away.

A special feature of the device is that the glue units 34, 35 on the one hand and glue units 40, 41 on the other hand can each be moved in pairs in one or more cleaning positions.

The glue units 34, 35 of the glue station 32 for the application of hot glue can be moved in the vertical direction, or substantially transversely to the transport path 24, namely in a cleaning position below the transport path 24. This cleaning position is in Fig. 7 shown. On the other hand shows Fig. 6 a glue application position of the glue station 32. In dashed lines is in Fig. 6 the cleaning position according to Fig. 7 indicated.

The glue units 34, 35 are mounted in the present case on a common, not shown in detail, support means 44, which is movable in the present case by means of a pneumatic cylinder 45 as a drive in the vertical direction. Of course, other drives come into question for this purpose.

The two glue units 34, 35 are supplied via hot glue lines 46 with hot glue. In this case, both the hot glue lines 46 are insulated or heated and the hot glue connections 47 of the hot glue lines 46 on the glue units 34, 35.

In the cleaning position according to Fig. 7 are the two opposite glue units 34, 35 with their nozzle tips 48 facing each other and on in Essentially the same height arranged. Between the glue units 34, 35 and the nozzle tips 48, a stationary collecting element 49 is arranged. The collecting member 49 serves to receive glue portions of hot glue, which are delivered in the cleaning position of the two glue units 34, 35 in order to prevent clogging of the glue units 34, 35. The collecting element 49 is arranged at a distance from the mutual nozzle tips 49 and prevents the mutual glue units 34, 35 from polluting each other with glue portions.

The catcher 49 has in the present case a wall-like shape with a substantially vertical extent. In cross section ( Fig. 7 ) side walls of the collecting organ 49 also converge downwardly converging. In this way, the glue dispensed by two glue units 34, 35 run on both sides of the collecting organ 49 down and drip from there into a collecting means 50, in particular in the form of a hot glue drip tray.

The hot glue collecting tray as collecting means 50 is mounted on guides 51, so that they can be pulled laterally out of the device to empty the tub and clean.

Another special feature is that the two glue units 34, 35 with respect to their relative position relative to the packs 10 and the transport path 24 are adjustable. On the one hand, the glue units 34, 35 are adjustable in the horizontal direction. This is done via adjusting screws 52. In this way, the lateral distance 53 of the glue units 34, 35 with respect to the packs 10 is adjustable. Furthermore, adjusting screws 54 for adjusting the height of the glue units 34, 35 are provided.

Another special feature is that the glue units 34, 35 are provided with an insulation 55, which also includes the area of the nozzle tips 48. To this end, the nozzle tips 48 are elongated over conventional nozzle tips, i. these protrude further out of the glue unit than usual. In this way, it is possible to arrange the insulation 55 also in the area surrounding the nozzle tips 48.

In order to prevent the glue portions emitted by the glue units 34, 35 from settling on the catching element 49, provision can furthermore be made for the catching element 49 to be designed to be heatable. For example, a central heating device 56 may be provided in the collecting element 49, which heats the walls of the collecting element 49 and thus prevents cooling and settling of hot glue in this area.

The two glue units 40, 41 can also be moved from an (upper) glue application position into a (middle) first cleaning position. This first cleaning position is in Fig. 8 shown. In this cleaning position, the glue units 40, 41 are below the transport path 24. Again, a collecting member 57 is provided for Kaltleimportionen that like the collecting organ 49 is positioned for the Heißleimportionen between the glue units 40, 41 and from the glue units 40, 41 delivered Leimportionen fields.

Below the collecting element 57, in turn, a collecting means 58 is provided for cold glue, for example in the form of a cold glue collecting tray, which can be pulled laterally out of the device in order to empty and clean them. A special feature of this drip tray is that it has a C-shaped floor plan and is angled twice starting from the area between the glue units 40, 41. The bottom of the collecting means 58 is formed inclined over the course, so that the collecting means 58 in the area between the glue units 40, 41 has only a small amount, but then increases continuously over the course. In this way, the collecting means 58, despite the small space in the area between the glue units 40, 41 overall a sufficient volume.

The glue units 40, 41 are also still in a further (lower) second cleaning position movable, which is in the present case below the first cleaning position. This (lowest) cleaning position is in Fig. 8 indicated by dashed lines. There are the glue units 40, 41 and their nozzle tips 48 on a pair of stationary rotatable cleaning rollers 59, which are driven synchronously via a common drive 60 and preferably made of foam. The cleaning rollers 59 is associated with a pair of other cleaning rollers 61, which are also rotatably mounted below the first cleaning rollers 59 and abut the cleaning rollers 59 and thus indirectly driven by the drive 60 with. The cleaning rollers 61 are immersed in a container 62 with a cleaning agent 63, in particular water, for cleaning the glue units 40, 10 or the cleaning rollers 59.

Also, the container 62 with the cleaning agent 63 is mounted laterally removable from the device. For this purpose, guide pins 64 are provided on which the container 62 is displaceably mounted in the longitudinal direction.

The height adjustment of the glue units 40, 41 success via a two pneumatic cylinders 65, 66 accordingly Fig. 9 , On the upper side and partly laterally, the pneumatic cylinders 65, 66 are each covered by protective devices 67, 68, so that they can be avoided by glue. Also, the glue units 40, 41 are mounted on a common support means to simultaneously move both organs together between the positions can.

The glue units 40, 41 do not necessarily have to be moved in the vertical direction. It is also conceivable to pivot the glue units 40, 41, as already described for the glue units 34, 35.

Another detail is in Fig. 10 shown. Accordingly, each glue unit 40, 41 for cold glue on two glue nozzles 69, which are arranged offset in the conveying direction of the packs 10 at a distance from each other and in height. The offset 70 of the nozzles, the two rows of points 38, 39 are generated.

Another special feature is that all the organs for gluing the packs 10 and for cleaning the glue units 34, 35; 40, 41 is connected to a common unit. The unit comprises in particular the glue units 34, 35; 40, 41 the drives for moving the glue units 34, 35; 40, 41 between the stations and the collecting device 49, 57 and collecting means 50, 58 and the container 62 with the cleaning rollers 59, 61st

All necessary organs are arranged in or on a common drawer 71. The drawer 71 is longitudinally displaceably mounted with double-sided rails 72 between pairs of sliding shoes 73, so that the drawer with the entire unit can be pulled laterally out of the device without the relative position of the individual members being changed relative to one another. On the underside, the drawer is supported by strips 76 on a machine bed 77. Independently of this, the collecting means 50, 58 and the container 62 can be pulled out laterally relative to the unit.

In order to prevent unintentional opening or pulling out of the drawer 71, a detent 79 is provided which works together with the longitudinal guide of the drawer 71. The drawer 71 can be locked accordingly in the retracted position, for example by a corresponding locking member.

Another functional detail is the supply of power to the glue units 34, 35; 40, 41. The power supply is bundled to a distribution box 74 laterally in or on the drawer 71. From the distribution box 74 from the individual units are supplied via power lines 75 with power.

Furthermore, a device for aligning folding flaps of the package 10 in the region of the lid 12 is arranged in the region of the glue units 40, 41, namely an aligner shaft 78. The aligning shaft 78 is arranged upstream of the glue units 40, 41, so that the cold glue is applied to the aligned folding flaps can. The operation of the aligner shaft 78 results from DE 100 31 319 A1 ,

The device described so far in its essential parts functions as follows: In the event of an interruption of the operation of the device, the glue units 34, 35; 40 41 moved to the cleaning position. For the glue units 34, 35 for the application of hot glue, this means that they are moved into the cleaning position for the delivery of glue portions below the transport path 24. The glue units 40, 41 are also moved to this position. Furthermore, the glue units 40, 41 can still be moved into the second cleaning position in contact with the cleaning rollers 59. This is done in accordance with a corresponding programming of a machine control for the device. The selection of the cleaning position to be approached can be made dependent in particular on the duration of the interruption.

Furthermore, it is possible for the operator of the system to cause a manual triggering of the delivery of glue portions by corresponding control buttons 80, 81 are actuated.
