Title: Apparatus for producing cigarette packs provided with coupons

Description:
BACKGROUND OF INVENTION 
   The invention relates to a method of producing (cigarette) packs which are provided with at least one blank, in particular with a coupon which is folded a number of times, the blanks or coupons being produced by a coupon-production means and fed to a packaging machine. The invention also relates to an apparatus for implementing the method. 
   During the production of cigarette packs, it is desirable or necessary for the latter to be provided with separate blanks. These may be (tax) revenue stamps which are to be applied to the pack in accordance with regulations. Alternatively or additionally, printing carriers, namely coupons, may be added to the pack. These may be folded a number of times in order to increase the size of the surface areas which can carry printing. The design and method of producing such folding coupons is known in principle. The operations of introducing coupons and other printing carriers into a container, namely into a magazine, and of fitting this in a magazine carousel in the region of the packaging machine also belong to the prior art (EP 1 125 843 A1). The coupons are removed one after the other in the downward direction from the shafts and fed to the packs. 
   SUMMARY OF THE INVENTION 
   The object of the invention is to coordinate the handling of the blanks or coupons with the production of the packs such that the necessary quantity of coupons is automatically made available, with little manual intervention, to the packaging machine. 
   In order to achieve this object, the method according to the invention is characterized by the following features:
         a) following the coupon-production means, the coupons are introduced into containers—magazines—to form stacks,   b) a number of containers, with correspondingly designed coupons, which corresponds to a batch of (cigarette) packs which is to be produced are provided with a marking, in particular with a readable (bar) code,   c) in the region of the packaging machine, the marking or the bar code of a container—magazine—is checked in respect of correct assignment, in particular by a reader.       

   Accordingly, the special feature of the invention is that the coupons produced in a coupon-production means assigned to a plurality of packaging machines are collected, and introduced into magazines, in the immediate vicinity of the packaging machines. The magazines are supplied to the packaging machine, as required, by a conveyor, in particular by a transporting vehicle. 
   According to the invention, a separate coupon arrangement thus comprises a coupon-production means, a distributor system for the coupons and a filling station. A plurality of coupons are produced simultaneously in one operating cycle, in a state in which they are distributed in the transporting direction, with the result that individual coupons following one after the other arrive at the filling station and are introduced into a respective magazine which is kept for this purpose. 
   One special feature resides in the coordinated control of the coupon arrangement, of the conveyors and of the packaging machines by preferably a central computer. The latter receives the data regarding the (cigarette) packs which are to be produced. The requirements for packaging material and coupons are determined therefrom. The computer then controls the production of the coupons and the availability thereof in accordance with the requirements for each packaging machine.

   DETAILED DESCRIPTION OF DRAWINGS 
   The exemplary embodiments illustrated in the drawings involve the production of (cigarette) packs and the production and handling of blanks, namely coupons  11  which are folded a number of times and are made of paper or similar material. The packs are produced and provided with the blank or coupon  11  in the region of a packaging installation  12 .  FIG. 1  shows a configuration with two packaging installations  12 . Each of these packaging installations  12  comprises a packer  13  and a machine for applying an outer wrapper made of film, a so-called cellophane wrapper  14 . In this case, the pack may be designed such that the coupon  11  is applied to the outside of the pack and a film is folded, with the coupon  11 , around the outside of the pack. 
   The packaging installation  12  is assigned an arrangement for producing and handling the coupons  11 , namely a coupon arrangement or assembly  15 . The latter is separate from the packaging installation  12 , in particular is spaced apart therefrom, but such that the coupons  11  can be fed to the packaging installation  12  via expedient conveying paths. 
   The coupon arrangement  15 , which is common, in particular, to a plurality of packaging installations  12 , essentially comprises a production subassembly, namely a coupon-production means  16 , a distributor system  17  and a filling station  18 . In the region of the filling station  18 , the blanks or coupons  11  are introduced into elongate containers, namely into shaft-like magazines  20 , to form coupon stacks  19 . These magazines, in turn, are transported to the packaging installation  12  and are kept there in the region of the packer  13  for processing purposes. In the case of the present exemplary embodiment, each packer  13  is assigned a magazine carousel  21 . The filled magazines  20  are inserted into the same. The packer  13  removes the coupons  11  one after the other from the magazines  20  in accordance with pack production. The magazine carousel  21  is preferably designed in accordance with EP 1 125 843. 
   In the case of the present exemplary embodiment, the coupons  11  are formed in a number of layers by corresponding folding. For this purpose, a web  22  of the material, in particular made of paper, is led through a folding subassembly  23  and folded a number of times in the region of the same. The folding subassembly  23  is known as a buckle folder. The web  22  is prepared by preliminary folding and by way of the folding subassembly  23  such that following the folding subassembly  23 , in the region of a severing means  24 , in each case four coupons  11  which are located one beside the other in the direction transverse to the conveying direction are produced simultaneously, to be precise by three severing cutters  25  located one beside the other. 
   The simultaneously produced (four) coupons  11  are transferred to the distributor system  17  immediately upon completion. This distributor system comprises a plurality of interacting endless conveyors and directing means. Coordination results in the coupons  11  being transported separately, that is to say individually, one after the other and then being distributed, to form coupon stacks  19 , over (two) filling subassemblies  26 ,  27  of the filling station  18 . 
   Each of the coupons  11  located one beside the other is assigned a conveyor, namely a receiving belt  28 ,  29 ,  30 ,  31 , on the outlet side of the coupon-production means  16 . On the one hand, these conveyors move the coupons  11 , during transportation, from a horizontally oriented starting position into a vertical position on the outlet side. For this purpose, the receiving belts  28  . . .  31  are twisted, namely with horizontally oriented deflecting rollers on the inlet side of the coupons  11  and upright deflecting rollers on the outlet side. 
   Furthermore, the relative position of the coupons  11  is changed during transportation, to be precise by virtue of different conveying characteristics and/or conveying speeds of the receiving belts  28  . . .  31 . Deceleration or acceleration results in the coupons  11  being offset in the transporting direction, with the result that the simultaneously fed (four) coupons  11  arrive one after the other on the outlet side of the belts  28  . . .  31 . In the case of the example shown, the border-side receiving belt  28  is driven at a lower speed than the adjacent receiving belt  29 , etc. 
   Following the receiving belts  28  . . .  31 , the coupons  11  are combined by intermediate conveyors  32 ,  33 , in the first instance, on two conveying paths. In each case two coupons  11 , in the present case those from the receiving belts  28 ,  29 , are fed to the common intermediate conveyor  32  and the coupons  11  from the other two receiving belts  30 ,  31  are fed to the second intermediate conveyor  33 . The intermediate conveyors  32 ,  33  have two pairs of endless conveyors on the entry side, these endless conveyors converging, that is to say coming together, in the conveying direction. The coupons  11 , which arrive one after the other in each intermediate conveyor  32 ,  33 , are transferred to a common collecting conveyor  36  via connection conveyors  34 ,  35 , which likewise converge in relation to one another. This collecting conveyor is designed analogously to the intermediate conveyors  32 ,  33  and leads the coupons  11 , which arrive in two paths, by way of converging conveying paths into a common movement path, and to an entry conveyor  37  of a distributor  38 , which is designed in a particular manner. This distributor transfers the incoming coupons  11  alternately to one filling subassembly  26 ,  27  or the other in order to form the coupon stacks  19 . 
   The distributor  38  is designed in a particular manner and has the task of feeding the individually arriving coupons  11 , which follow one after the other, to one filling subassembly  26 ,  27  or the other of the filling station  18 . For this purpose, the entry conveyor  37  (comprising two upright belts butting against one another) is followed by two diverging conveying units, namely (pairs of) transfer conveyors  39 ,  40 . Each of these transfer conveyors  39 ,  40  leads (indirectly) to a filling subassembly  26 ,  27 . The transfer of the coupons  11  from the entry conveyor  37  to one transfer conveyor  39 ,  40  or the other can be adjusted, to be precise preferably in a controlled manner in accordance with requirements. For this purpose, a diverter or a directing means  41  is arranged in the region where the coupons are transferred to the transfer conveyors  39 ,  40 , namely in the region of a gap which is produced here. The directing means  41  is of more or less triangular design here and can be pivoted about a vertical axis of rotation. This results in lateral guide surfaces which, depending on the position of the directing means  41 , connect the entry conveyor  37  to one transfer conveyor  39 ,  40  or the other in order to guide the coupons  11  correspondingly. 
   The filling station  18  and, in particular, the filling subassemblies  26 ,  27  constitutes/constitute a special feature. In the region of the filling station  18 , on the one hand, the coupon stacks  19  are formed and introduced into the magazines  20 . Furthermore, the filled magazines  20  are transferred to a conveyor in order to be transported to one packer  13  or the other. 
   In the case of this exemplary embodiment, the coupon or magazine conveyors are designed as transporting carts  42 ,  43 . These run on wheels and, here, can be displaced by hand. Each transporting cart  42 ,  43  comprises an undercarriage  44  and a bearing means for the upright magazines  20 , comprising a bearing plate  45  and upright, lateral supporting walls  46 , which are arranged in a U-shaped manner, such that a side which is directed toward the filling subassemblies  26 ,  27  is open. The magazines  20  are positioned in rows one beside the other on the bearing plate  45 . A quantity of magazines  20  or coupons  11  which corresponds to the respective requirements is fed to the respectively predetermined packer  13  with the aid of the transporting cart  42 ,  43 , in the present case by way of an operator (machine controller). The latter inserts the magazines  20  into a magazine carousel  21  in the region of the packer  13 . 
   The filling station  18  is designed such that two transporting carts  42 ,  43  can be positioned one beside the other. 
   The conveyors or transporting carts  42 ,  43  are also intended for returning empty magazines  20  (transporting cart  42  in  FIG. 4 ). The filling station  18  and/or the filling subassemblies  26 ,  27  operates/operate so as to accommodate empty magazines, by removal from the transporting cart  42 . The filled magazines  20  are guided back and set down on the bearing plate  45  of the other transporting cart  43 . For this purpose, the filling station  18  is assigned a lifting and conveying arrangement, namely a gantry-type conveyor  47 . The latter comprises two spaced-apart longitudinal members  48 ,  49 , laterally alongside the parking position of the transporting carts  42 ,  43 . A transverse member  50  can be displaced, in accordance with the double arrow, on the fixed longitudinal members  48 ,  49 . In one of the end positions ( FIG. 4 ), the transverse member  50  is directed toward the filling subassemblies  26 ,  27 . A means for accommodating the magazines  20  is fitted on the transverse member  50 , to be precise such that it can be displaced in the longitudinal direction of the transverse member  50 , that is to say transversely to the longitudinal members  48 ,  49 . The accommodating means comprises an upright carrying arm  51 , which is fitted on the transverse member such that it can be moved up and down and can be displaced in the transverse direction. The carrying arm  51  has a securing means for a respective magazine  20  at the bottom end. In the case of the present exemplary embodiment, the securing means comprises a transversely projecting leg  52  and a (clamping) holder  53  which is arranged at the end thereof and is intended for gripping the magazine  20  laterally. The holder  53  or the leg  52  can be rotated about a vertical axis of the upright carrying arm  51 , with the result that different angle positions are possible for the purposes of accommodating the magazine  20 , and setting it down, in a precisely positioned manner. 
   Empty magazines  20  are fed one after the other to one filling subassembly  26 ,  27  or the other and correspondingly filled magazines  20  are taken back and set down on the relevant transporting cart  42 ,  43 . During this transportation of the magazines  20 , the transverse member  50  is displaced along the longitudinal members  48 ,  49 , the carrying arm  51  is adjusted on the transverse member  50  as required and, finally, for precise positioning, the leg  52  with holder  53  is pivoted. 
   The empty magazines  20  are set down on an underlying surface  54  of the filling subassembly  26 ,  27 , namely on a bottom supporting plate. The set-down position is selected such that the magazine  20  can be gripped and transported away by a conveyor of the filling subassembly  26 ,  27 . This is a magazine conveyor  55 , which comprises two endless belts which are spaced apart one above the other. These are arranged centrally within the filling subassembly  26 ,  27  and transport the magazines  20  one after the other along a U-shaped movement path, the magazines  20  being supported for sliding action on the underlying surface  54 . The magazine conveyor  55  or the belts thereof has/have carry-along elements, namely in each case two carry-along elements  56 ,  57  which are spaced apart from one another in accordance with the transverse dimensions of a magazine  20 . In each case one magazine  20  is positioned between these carry-along elements. An all-round guide wall  58  is provided as an outer guide, the magazines  20  butting with sliding action against this guide wall during transportation. The guide wall  58 , which runs along both sides, is open, and set back, on the side which is directed towards the gantry-type conveyor  47 , with the result that it is possible for the magazines  20  to be transferred to the magazine conveyor  55  and/or set down on the underlying surface  54 . 
   The empty magazines  20  are transported into the filling region by a strand of the magazine conveyor  55 , to be precise in the region of a returning conveying path of the magazines  20 , in the case of the exemplary embodiment according to  FIG. 4  in each case in the region of outer movement paths. The cyclically transported magazines  20  here pass into the region of a filling location  59  beneath one end of introduction conveyors  60 . These follow the transfer conveyors  39 ,  40  and cause the coupons  11  to be fed to the magazine  20  which is kept in the filling location  59  in each case. The introduction conveyors  60  are formed by a corresponding arrangement of deflecting rollers such that, during transportation, the coupons  11  are rotated back into an essentially horizontal relative position. The coupons  11  are introduced directly into the respective magazine  20  by a filling conveyor  61 , which comprises two interacting belts which are guided over a plurality of deflecting rollers and of which a top belt has a horizontal sub-region extending into a top introduction opening of the magazine  20  and the other belt has an upright supporting section extending in the region of an upright sub-opening of the magazine  20 , with the result that each coupon  11  is guided precisely between two belts and is deposited in the magazine  20  to form a coupon stack  19 . The incoming coupons  11  here are conveyed in the direction of an upright magazine wall located opposite the inlet side. A sensor  62  checks the correct introduction of the coupons  11  or the correct feed of the same. 
   Accordingly, the coupon stack  19  formed in the magazine  20  is built up from above, the coupons  11  within the magazine  20  resting on a lowerable support. This is formed by (two) upright supporting push rods  63 , which, via openings in a bottom wall of the magazine  20 , are moved upward within the latter and, during the filling operation, are lowered from a top, starting position, as the degree of filling in the magazine  20  progresses, until the magazine  20  has been filled completely. For the filling operation, the (initially empty) magazines  20  are raised, using lifting push rods  64 , from the plane of the underlying surface  54  to a higher-level platform  65 . Processing means, that is to say the filling conveyor  61 , are positioned such that the magazines  20  have to be raised, in relation to the feeding plane, to the level of the platform  65 . The lifting movement takes place relative to the magazine conveyor  55 , namely relative to the two belts of the same. The difference in level for the magazines  20  is caused by the relative position of processing means, in particular by the position of the filling conveyor  61 . The lifting movement of the magazine  20  results in the latter passing directly and precisely into the filling position alongside and/or beneath the filling conveyor  61  ( FIG. 6 ). 
   The filling operation within the magazine  20  is monitored from the outside, to be precise by sensors  69 ,  70 . These check the correct position of the coupons  11  and the progression of filling in the top region of the magazine. The sensors  69 ,  70  are directed onto the coupon stack  19  via openings  71  in an upright side wall of the magazine  20 . Any incorrect positioning of the coupons  11  in the magazine  20  triggers an error signal. 
   Following the filling location  59 , the filled magazines  20  are fed by the magazine conveyor  55  to a closure station  66 . In the latter, the filled magazines  20 , which are open on the top side, are (partially) closed by having a closure means, namely a closure strip or a tape  67 , applied. This is necessary because the magazines  20 , for use in the packer  13 , are turned such that the open side, which is directed upward during filling, is turned downward for removal of the coupons. The closure means or the tape  67  is removed for this purpose. 
   Arranged in the region of the closure station  66  is a tape subassembly  68  which is designed, and operates, in a particular manner and is intended for applying the closure strip or the tape  67 . 
   The tape  67  is preferably designed such that it is anchored in a releasable manner by adhesive bonding on the outside of mutually opposite upright walls of the magazine  20 . In order for the tape  67  to be easily removed by being pulled off (manually), a leg  73  is formed at one end of the tape  67  by folding over, to be precise by folding over one tape end through 180°. This leg  73  is connected to the magazine  20  in the top region by adhesive bonding. The tape  67 , which extends transversely over the open side of the magazine  20 , is fastened, likewise by adhesive bonding, on the opposite side of the magazine  20  by way of a downwardly directed endpiece  74 . An adhesive-free gripping tab  75  allows the tape  67  to be removed, in particular, manually when the filled magazine  20  is opened for the first time. 
   A tape subassembly  68  for applying the strip or tape  67  constitutes a special feature. The tapes  67  are provided on a carrier band  78  which is pulled off from a reel  77 , to be precise above the movement path of the magazines  20 . The tapes  67  are designed such that areas of glue are applied to opposite sides, at the end regions in each case, for the purpose of connecting the leg  73  and the endpiece  74  to the magazine  20 . On account of the design of the tape  67 , the areas of glue are located on opposite sides of the tape  67 . The empty carrier band  78  is wound as an empty reel  79 . The carrier band  78  is guided around a press-on roller  80  and deflected from a downward direction into an upward direction. In the region of this deflection, the tape  67  is transferred to the magazine  20 , to be precise in a functional sequence according to  FIGS. 9 to 12 , with continued conveying movement of the magazine  20 . The latter is moved past the tape subassembly  68 , and receives the tape  67  in the process. 
   The press-on roller  80  is fitted on a pivotable carrying lever  81 . The latter is biased into a certain starting position ( FIG. 9 ), in a direction counter to the incoming magazine  20 , by a (tension) spring  82 . The relative positions of the carrying lever  81  and the press-on roller  80  are selected such that a top border region of the incoming magazine  20  comes into contact with the press-on roller  80  and pivots the carrying lever  81 , with continued movement counter to the biasing of the spring  82 , counterclockwise about a rotary bearing  83 , namely in the conveying direction of the magazine  20 . In this case, in the first instance, the leg  73  with the adhesive layer is pressed onto the magazine  20  ( FIG. 10 ). Thereafter, as pivoting of the carrying lever  81  continues, the press-on roller  80  moves along the top side of the magazine  20 , pressing on the tape  67  in the process. In an end position of the press-on roller  80  and carrying lever  81  ( FIG. 11 ), the carrying lever  81  is freed and is moved back into the starting position by the spring  82  ( FIG. 12 ). 
   The operation of applying the tape  67  is then completed by a pressure-exerting roller  84 . The latter is mounted in a stationary manner on a pivoting lever  85  above the movement path of the magazine  20 . The pivoting lever  85  can be moved by a drive, namely by a motor  86 . The latter executes, via a shaft, a (controlled) pivoting movement of the pivoting lever  85 , the pressure-exerting roller  84  being pressed onto the tape  67  in the process. The movement of the pivoting lever  85  and thus of the pressure-exerting roller  84  are controlled such that, in an end position ( FIG. 12 ), the pressure-exerting roller  84  folds the endpiece  74  of the tape  67  over a top edge of the magazine  20  into an upright plane, the endpiece  74  with the adhesive being pressed onto the upright side wall of the magazine  20  in the process. 
   In the region of the tape subassembly  68 , the magazines  20 , which are open at the top, are assigned a holding-down means. This is formed by two endless belts  87 ,  88  which grip the magazine  20  at peripheral regions of the open side ( FIG. 8 ). The preferably driven endless belts  87 ,  88  cause the coupons  11  stacked in the magazine  20  to be pressed down counter to a material-induced restoring force of the folded coupons  11 . 
   It is particularly important to integrate production and handling of the coupons  11  in the production process of the packs. A basic precondition for this is the labelling or marking of the magazines  20  with coupons  11  of a certain configuration. The marking takes place in the region of the detachable closure means, namely of the tape  67 . In particular a readable code, for example a bar code, is applied to the tape  67  by printing. For this purpose, the filling station  18  is provided with a printer  89  above the movement path of the magazines  20  following the closure station  66 , for the purpose of printing the (bar) code on the tape  67 . 
   The processing machine, that is to say the packer  13 , is provided with a reader  90  for the code on the magazine  20  or on the tape  67 . The reader  90  is positioned, in particular, in the region of the magazine carousel  21 , with the result that accuracy is checked at this location, namely prior to the coupons  11  being introduced into the packer  13 . 
   In order to integrate coupon production in a (central) control means of the packaging installation, the coupon arrangement  15  or the coupon-production means  16  is connected to a central control unit  91 . The latter is likewise connected to the packaging installation  12 . The production of a certain type of (cigarette) pack including associated coupon  11  is entered as a program into the central control unit  91  or into a computer of the same. Accordingly, the quantity of packaging material, pack contents and the quantity of coupons  11  which are to be produced are calculated. The packaging material is made available to the machines. Furthermore—in advance of production of the packs—coupon production is initiated, the quantity of coupons  11  which are to be produced being predetermined and the printer  89  being activated in order to apply the code. Finally, the quantity of coupons  11  which is necessary for the relevant batch of packs is kept on one or more transporting carts  42 ,  43 , where possible in a separate store in the vicinity of the machines. At the beginning of pack production, the coupons  11  or magazines  20  are called up and the transporting carts  42 ,  43  are fed to the machines or the packer  13  in accordance with the quantity which is to be produced. The magazines  20  may also be transported by way of automatically operating vehicles, to be precise either ground-level vehicles or transporting equipment which can be displaced on overhead conveyors. It is also the case that the magazine carousel  21  and the reader  90  are connected to the control unit  91 , with the result that detected errors in the region of the magazines  20  lead directly to an error signal being triggered. In the case of automatic conveying arrangements for the coupons or magazines, it is also possible for the conveying installations to be connected to the control unit  91 . Furthermore, it is alternatively or additionally possible for codes to be applied to the transporting cart  42 ,  43  itself, to be precise even such information as can be read directly. Corresponding marking cards or other data carriers may be produced directly by the printer  89  and applied to the transporting cart  42 ,  43 .
