Description

  The invention relates to a method for the manufacture of a package according to the preamble of claim 1. Furthermore, the present invention also relates to an apparatus for performing this method.

The package to be manufactured is made up of a foldable packaging material which is supplied as a continuous strip of material in the range of the processing or packaging machine and from which the cutting for the package is cut off. This packaging material is provided with a fold line for forming a fold edge portion, particularly a package edge portion, formed by material deformation based on the material thickness and / or shape stability. Usually this is also true for packaging materials having a material weight much greater than 100 g / m ² (paper). Paperboard having a material weight preferentially of about 140 g / m ² or more is a problem. Blanks made from this material are provided with punched or cut lines for defining folds and / or perforations for creases. Such a blank can preferably be formed according to an example based on German patent application 1020111055.9.

  The treatment of continuous strip material is the subject of US Pat. The application required for blank processing is applied by assigning to one blank in a continuous band range. This blank is then separated from the strip and fed to the packaging process. The above example relates to the manufacture of a soft package for tobacco. For the manufacture of a package consisting of a paperboard blank, i.e. a box with a lid for cigarettes, continuous band processing is also known (Patent Document 2). Here too, stamping and punching are performed in the region of the material strip, after which the manufactured blank is separated from the strip. On the other hand, deformation or punching, cutting and punching takes place in this blank immediately after separation of the blank.

German Patent Invention No. 69400120 European Patent No. 08880909

  The object of the present invention is to further develop the production of blanks made of packaging materials that can be folded and have increased shape stability with respect to paper, and in particular the accuracy in the execution of applications (stamping, punching). It is based on improvement.

  In order to achieve the object, a method according to the invention having the features of the characterizing part of claim 1 is carried out.

  The present invention is based on the recognition that after separation of the blank from the strip, applications with higher accuracy and higher efficiency can be applied to this blank. The separated blanks are preferably fed continuously to the application facility. In that range, the fold line is made by punching and punching for the folds, controlled by the printing marker. The manufactured blank is subsequently fed to a folding facility, in particular a folding turret. Depending on the purpose, the (outside) printing is done in a strip of material in the area of the print section or in the packaging machine according to the design of the package.

  The apparatus comprises a device for feeding a strip of material to a cutting or punching member for separating the blank, and a blanking unit and a punching unit, preferably a slotting roller and a cutting roller, and a punching unit and punching. And a delivery facility for supplying the unit.

  The characteristic is in the drive part of the several member of an apparatus. In particular, the conveying members such as the preceding roller, the conveying roller, and the direction changing roller are driven by individually controllable servo motors. The punching unit and punching unit (application equipment) are connected in particular to a central mechanical drive which is the “spindle”.

It is a figure similar to FIG.9 and FIG.10 which shows the detailed part of a launch tool. FIG. 6 is a detailed view of the packaging machine corresponding to FIG. 5 for a modified embodiment.

  Other features of the method and apparatus are described in detail below with reference to the drawings.

The technology can be used for packages comprising or comprising at least one blank 10, preferably made of thin paperboard. A special application is a modified soft package or soft cup package (FIG. 1) with an outer package 11 made of paperboard, which application has a material thickness or material strength of 140 g / m ² . . The illustrated example is a cigarette package, in which a cigarette block having an inner blank or an aluminum foil blank forms a closed cigarette block 12. The cigarette block is open on the upper side and is arranged in a cup-shaped outer package 11. On the open side of the outer package 11, the tobacco block 12 protrudes slightly from the outer package 11. A laterally-oriented band seal 13 extends over the end face side of the package.

  The unfolded blank 10 shown in FIG. 3 is for the front side wall 14, the back side wall 15, the closed side wall 16, and the side wall 19 formed by the edge pieces 17, 18. The edge pieces 17 and 18 are formed. Specially, a bottom wall 20 is formed. The bottom wall portion is composed of a trapezoidal inner piece 21, a triangular intermediate piece 22, a side piece 23 in the range of the side walls 16 and 19, and an outer covering piece 24. Essentially, the surface of the bottom wall portion 20 is covered outside.

  The blank 10 according to FIG. 3 or other implementation has a number of applications. In the embodiment shown, the deformation of the material of the blank 10 is important, in particular the multiple creasing stations for the formation of the longitudinal edge 25 and the multiple creasing for the formation of the lateral edge 26. It is. Long edge 25 in a parallel arrangement defines blank areas 14-18 and forms a vertical package edge. The lateral edge portion 26 defines a boundary with respect to the bottom wall portion 20 of the package wall portions 14 to 18. The typed lines 25 and 26 end at intervals in the range of the intersection. Therefore, each creasing station has a predetermined length.

  Other applications exist in the range of the bottom wall 20 or the edge strip with the folds 21-24 of the bottom wall 20. The fold pieces 21, 22, and 23 are defined by intersecting fold lines 27 and 28 in an oblique direction. These can be formed as pre-scheduled material breaks, especially perforations. The fold lines 27 and 28 are arranged at an acute angle with respect to each other and intersect each other in the range of the back package corner (after the outer package 11 is completed). A covering piece 24 which is assigned to the front side wall part 14 or arranged in an extension thereof is defined laterally by a cutting line or a punching line 29. Both linear punching lines 29 extend to an extension of the longitudinal edge 25 defining the front side wall 14.

  Furthermore, in this embodiment, the front side wall part 14 is provided with a (decorative) shaping, and here is provided with an emblem 30 formed as a launching part that protrudes outward in particular for the material of the blank 10. (FIG. 1).

  One feature is the manufacture of the blank 10 in the range of packaging machines. In the present embodiment (FIG. 4), the packaging machine shown schematically for the production of cup packages, which has so far been a “soft cup package” configuration, is important. The core equipment of such a packaging machine is a folding turret 31 having a receiving part for each one blank 10 and a folding device (mostly not shown) for folding the blank 10. Here, the accommodating portion is a plurality of folding rods 32, that is, a hollow body having a rectangular shape in cross section while being arranged in parallel with the axis, and the folding rod accommodates the blank 10 to be folded outside.

  A special cutting facility 33 is assigned to the packaging machine. This cutting equipment is supplied with a material strip 34 which is in particular a paperboard strip. The material band 34 is pulled out from a bobbin (not shown) in accordance with the purpose. In the range of the cutting equipment 33, the plurality of blanks 10 are separated from the material band 34 along with each other, and supplied to the packaging machine or the folding turret 31 after processing.

  The cutting facility 33 (FIG. 5) essentially transfers the band guide 35, the separation unit 36 for separating the blank 10 from the material band 34, the application facility 37, and the blank 10 to the folding turret 31. And a delivery facility 38 for this purpose. These units are arranged functionally continuously.

  Preferably, the material band 34 that is completely printed on one side according to the package design is supplied to the edge control unit 40 via the direction change roller 39, and in this range, the material band 34 that is continuously conveyed has its longitudinal length. Accurate orientation with respect to the edge.

  Following this, the material strip 34 reaches the range of the separation unit 36. This separation unit is constituted by a cutter roller 41 having a counter cutter 42 fixed here. An adjustment unit is provided in front of the separating device formed in this way, and this adjustment unit controls the separation part accurately with respect to printing, in particular on the basis of a printing marker attached to the material strip 34. . The drive part of the material band 34 adjusted with respect to the operation of the separating device is constituted by a band roller 43 having an opposing pressing roller 44. The precise feed movement of the band 34 by the band roller 43 is effected by a print marker reader 45 which recognizes the position of the print marker in the area of the turning roller 46 and sends a control signal to the band roller. It transmits to 43 drive parts. Thereafter, the precise positioning of the separation part for the blank 10 is controlled. The belt roller 43 is driven by a servo motor 47 controlled by a printing marker reader 45.

  The blank 10 with (complete) printing is supplied to the application facility 37. Following the separation equipment 41, 42, a blank is received by a conveyor, here a delivery roller 48 formed as a suction roller. This transport device is also controlled to ensure that the blank 10 is delivered to the application facility 37 in the correct relative position. A blank separation edge is detected by the edge sensor 49, and thereafter, the drive unit of the transfer roller 48 is controlled by the servo motor 47 in the same manner.

  In the range of the application equipment 37, different material deformations and punching are performed in the blank 10 (FIG. 3). For this purpose, the application equipment 37 is provided with a plurality of different tools corresponding to the respective applications and for performing deformation and / or punching during the conveyance of the blank 10.

  In the embodiment of FIG. 5, there are provided two processing tools that rotate in parallel with the axis, ie, a forming roller or a discharge roller 50 and a cutting roller 51 (following in the conveying direction). The ejection roller 50 includes a plurality of protrusions that are ribs 53 extending in the circumferential direction and a rib portion 53 extending in the circumferential direction along the circumference. Due to this surface configuration of the launch roller 50, a groove-like deformed portion or recess for forming the longitudinal edge portion 25 on the one hand and the lateral edge portion 26 on the other hand is formed on the blank 10. The launch roller 50 cooperates with a counter member, here a counter roller 54. The counter roller 54 has a peripheral surface that is smooth, that is, does not have a recess in the range of the launching member, in accordance with the purpose. Thereby, the punched material deformation essentially occurs only by pressing the material of the blank 10 (FIG. 9). The blank 10 is preferably positioned in the area of the application equipment 37 so that the inner side faces the application equipment, in particular the ejection roller 50 and the printed outer side is in close contact with the counter member or counter roller 54. ing.

  The next second application tool is a cutting or punching tool for performing separate cutting, perforation or the like. In this embodiment of the blank (FIG. 3), the cutting cutter 55 that is parallel to the axis or oriented in the lateral direction is for forming the punching line 29 and the perforation cutter 56. These cutting members or punching members are arranged in a relative position, which corresponds to the corresponding shape of the blank 10, here the range of the bottom wall 20. In order to form the folding lines 27 and 28, a plurality of corresponding rows of the plurality of perforation cutters 56 arranged at intervals are arranged around the cutting roller 51 with respect to each perforation line.

  The processing rollers 50, 51 are adapted to the role of the individual application with regard to form and dimensions. The ejection roller 50 includes a rib 52 and a rib portion 53 in the range of the cylindrical roller portion 57. Outside the roller portion 57, the diameter of the launch roller 50 is reduced. Correspondingly, the cutting roller 51 here comprises a narrow roller part 58 arranged at the edge, this roller part comprising cutting tools 55, 56 on the outer surface.

  The movements of the members are coordinated with each other in terms of (transport) speed. In accordance with the purpose, the delivery roller 48 is driven at a higher conveying speed than the material band 34 in the range of the separation unit 36. In order to separate the blank 10 from the separating unit 36, it is reasonable to increase the speed of the delivery roller 48 by 4%. Each member of the application equipment 37 again has a conveying speed that is preferably 8% greater than the delivery roller 48. This also applies to the rotational speed or conveying speed of the rollers 50, 51 and 54 in the embodiment of FIG.

  In addition to the technically negotiated application, the application facility 37 can cause a decorative deformation, here the emblem 30. For this purpose, a corresponding protrusion 59 having the contour of the emblem 30 is arranged on the outer surface of the launch roller 50. In the present embodiment, the correspondingly formed recess 61 is assigned to the protruding portion 59 of the ejection roller 50 in the range of the counter member which is the outer surface of the counter roller 54 here.

  One characteristic is that in the embodiment based on FIGS. 5 and 6, (two) application facilities 50 and 51 are assigned to a common counter roller 54. The ejection roller 50 and the cutting roller 51 are arranged so as to cooperate with the counter roller with a shift in the circumferential direction of the counter roller 54. The cooperating rollers 51, 52, 54 are preferably driven individually, in particular on the basis of geared coupling to the central mechanical drive. A plurality of bevel gears 60 are symbolically assigned to the members in order to show their geared connection with the mechanical drive (main shaft).

  The blank 10 having the above-described application is individually and continuously conveyed along the blank path 62 following the application equipment 37 and delivered to the supply roller 63. The supply roller is formed as a suction roller and is coupled to a central mechanical drive. An intermediate roller 64 that takes over the blank 10 from the blank path 62 and abuts the periphery of the supply roller 63 by an outer guide and corresponding direction change is disposed in front. The intermediate roller 64 is also a member for accurately delivering the blank to the supply roller 63 at the same time. As a result, the supply roller is provided there with a relative position matched to the folding turret 31 or folding bar 32. For this purpose, another edge sensor 65 is assigned to the intermediate roller 64 for the detection of the lateral edge of the blank 10. The edge sensor 65 controls a servo motor 47 as a driving unit for the intermediate roller 64. Delivery of the completed blank to the folding turret 31 is performed by an appropriate and known method.

  7 and 8 schematically show a developed view (FIG. 7) of the outer surface of the ejection roller 50 on the one hand and a developed view (FIG. 8) of the outer surface of the cutting roller 51 on the other hand. The situation in the range of the roller parts 57, 58, respectively, is shown. It can be seen from FIG. 7 that two blanks 10 having an appropriate interval in the circumferential direction of the ejection roller 50 are accommodated based on the corresponding dimensions. Therefore, at full rotation, two blanks 10 are provided in the application. The roller portion 58 of the cutting roller 51 is correspondingly formed and measured (FIG. 8).

  Here, the formation of tools or operating means of the application equipment, which are rollers 50, 51, 54, is exemplarily shown in FIGS. FIG. 9 shows the formation of a launch roller 50 having a protrusion or rib 52 and a counter roller 54 having a smooth surface. This alternative is illustrated in FIG. Here, the ribs 52 are assigned groove-shaped recesses 66 of corresponding dimensions but having a rounded cross-sectional shape. The material of the blank 10 is pressed into the recess 66 during the formation of the folded edges 25, 26 under deformation and formation of deeper grooves in the material.

  From FIG. 11, it can be seen that the cutting tool and the punching tool of the application equipment 51 are formed in a cutter shape having a sharp cutting edge. This cutting edge completely penetrates the material of the blank 10 until it contacts the outer surface of the counter roller 54.

  FIG. 12 shows details for launching the blank 10 for the addition of the emblem 30, for example. A mold member 67 (removable) is attached around the launch roller 50. This mold member is provided with a projecting portion and a recessed portion in accordance with the launch portion to be formed. Correspondingly, the outer surface of the counter roller 54 is provided with a protrusion 66 or a recess 66 that fits the mold member 67.

  An alternative arrangement for the device according to FIG. 5 is shown in FIG. The same or similar members in the apparatus are given the same reference numerals. The difference particularly relates to the formation of the application facility 37. Counter rollers 68 and 69 are assigned to each application facility, that is, the ejection roller 50 on the one hand and the cutting roller 51 on the other hand. This unit is therefore composed of four rollers 50, 51 or 68, 69 which are parallel to the axis. The blank 10 is conveyed through the application equipment 37 thus formed along a horizontal path. Transmission of material deformation or punching and punching / cutting proceeds in the same manner as described above.

  Advantageously, all application runs are in a blank 10 separated from a material strip 34. However, for technical reasons, it is also conceivable to carry out individual applications, for example stamping and / or punching, in the region of the material strip 34, or to perform other or most applications in individual blanks.

  The present technology is particularly suitable for different shaped packages or boxes for tobacco packages as long as the package part (outer package) consists of thin paperboard. A box with a folding lid for cigarettes can also be produced as described above.
