Definitions

  • the invention relates to a device for shaping or preforming blanks for hinged boxes with rounded or polygonal longitudinal edges, with a forming station, in which the blanks are shaped by movable shaping tools, in particular by shaping rollers in connection with shaping plates, and then transported on.
  • Folding boxes - also called hinge-lid packs - are a common type of pack for cigarettes. Such folding boxes have recently been designed with rounded upright longitudinal edges or with bevelled, polygonal longitudinal edges.
  • the invention has for its object to further develop and improve a molding unit of this or other type in such a way that a higher performance in the molding or preforming of blanks for packages is achieved.
  • the device according to the invention is characterized in that the molding station has at least two molding units with molding tools, with means for alternately feeding blanks fed one after the other into the molding station to one and the other molding unit.
  • the performance of the device or of the entire packaging machine is increased according to the invention in that the shaping processing of the blanks in the shaping station is carried out simultaneously or overlapping on several blanks.
  • two complete molding units are arranged laterally next to a conveyor track for the blanks, approximately in the same plane as these, to which blanks are alternately fed by transverse movement. During the molding of a blank by one molding unit, a subsequent blank is fed to the other molding unit.
  • molding tools of one and the other molding unit for receiving a blank, in particular a molding plate are moved transversely. In a middle position will be first a shaped blank is delivered, namely transported on and then a new blank is added.
  • the molding tools can advantageously consist of a molding plate with shaping longitudinal edges and movable molding rollers.
  • the exemplary embodiment of a device or part of a packaging machine shown in the drawings relates to the production of hinged boxes 10 with rounded longitudinal edges 11, 12 in accordance with US Pat. No. 4,753,383.
  • a blank 13 is used, which also in U.S. 4,753,383.
  • the blank 13 is preformed in the area of the longitudinal edges 11, 12. Strip-shaped areas of the blank 13 between side tabs 14, 15 on the one hand and a central part of the blank on the other hand are shaped into a round shape.
  • the pre-treated blank 13 is then fed to a suitable packaging machine.
  • a folding turret 16 is shown as part of the packaging machine, which can correspond to the folding turret shown in US Pat. No. 4,084,393.
  • a shaping station 17 is arranged upstream of the packaging machine or the folding turret 16 for shaping or shaping pretreatment of the blank 13.
  • the unfolded blanks 13 are taken from a customary blank magazine 18 below, in the present case by a so-called unwinder 19.
  • the blanks 13 are then placed at predetermined intervals along a blank web 20 in a horizontal or in a slightly sloping (inclined) plane in the conveying direction Forming station 17 supplied.
  • conveyor elements namely first conveyor rollers 21 and second conveyor rollers 22, are arranged in the region of the cutting path 20.
  • the conveyor rollers 22 facing the forming station 17 are also coding elements for the blank 13.
  • molding tools which deform the longitudinal edges 11, 12 of the blank 13 during a current standstill phase with the formation of curves.
  • These molding tools are, on the one hand, a stationary molding tool, namely a molding plate 23 with lateral shaping, in the present case semicircularly rounded longitudinal edges 24, 25.
  • the cross-sectional rounding of these longitudinal edges 24, 25 corresponds to the rounding of the longitudinal edges 11, 12.
  • two movable molding tools work together, namely elongated molding rollers 26 and 27. These are arranged in a stationary manner, but are movable.
  • the molding tools described above, namely molding plate 23 and two molding rollers 26, 27 form a molding unit 28, 29.
  • the shaping takes place within this molding unit 28, 29 in such a way that the blank 13 is fixed to the underside of the molding plate 23 by abutting it .
  • the shaping rollers 26 are moved from a lower starting position below the shaping plate 23 and below the blank 13 with entrainment of the side tabs 14, 15 around the longitudinal edges 24, 25 of the shaping plate 23 while rolling on them up to the top (Fig. 4).
  • the areas of the blank 13 to be rounded are pressed against the longitudinal edges 24, 25 and are given the round shape.
  • the shaping rollers 26, 27 then return to the starting position below the shaping plate 23.
  • the preformed blank 13 can now be transported further, namely to the folding turret 16.
  • the molding station 17 is equipped with two molding units 28, 29, each of which has a complete set of molding tools.
  • the molding units 28, 29 lie on both sides of the cutting path 20, which accordingly runs between the molding units 28, 29.
  • the supplied blanks 13 are successively fed to one and the other molding unit 28, 29 by a sideways movement (arrow 30 or 31), deformed and then moved back according to arrow 32 or 33 into the middle position, that is to say into the blank web 20.
  • the cut treated in each case is then transported away, inter alia by a central conveyor roller 34.
  • the mold plates 23 in the exemplary embodiment shown can be moved transversely as part of each mold assembly 28, 29.
  • a receiving position in the middle of the molding station 17, that is to say in the cutting path 20 an unshaped blank 13 is fed to the respective molding plate 23, specifically in the region of the underside of the molding plate 23.
  • the blank is here applied to a contact surface 35 of the molding plate 23. This is provided on the underside with holding members for fixing the blank 13.
  • the suction members 36 are effective on the underside, namely on the contact surface 35, and are subjected to negative pressure from above.
  • the mold plates 23 therefore also fulfill the function of a blank holder.
  • the mold plates 23 have a double function as a mold and blank holder.
  • the molding plate 23 With the blank 13 fixed in this way, the molding plate 23 is moved sideways to the associated molding unit 28 or 29. In this sideways position next to the blank web 20, the shaping is then carried out in the manner described.
  • the transverse movements of the mold plates 23 of the mold assemblies 28, 29 are coordinated with one another.
  • the two mold plates 23 of the mold assemblies 28, 29 are connected to one another.
  • a bridge 38 is provided, the upright legs 39, 40 of which are connected to the upper side of the mold plates 23.
  • the bridge 38 can be moved laterally as a unit. Corresponding movements of the bridge 38 therefore lead to a simultaneous movement of the two mold plates 23.
  • One mold plate 23 is therefore always moved out of the associated mold assembly 28, while the other mold plate is moved into the associated mold assembly 29.
  • the bridge 38 is connected to a push rod 41 which is slidably mounted in a supporting wall 42.
  • the free end of the push rod is connected to an actuating member, in the present case with a feeler roller 43, which runs in a cam groove 44 of a control member 45 driven in rotation.
  • the reciprocating movements of the push rod 41 are generated by the rotary movement of the cylindrical control member 45.
  • each mold plate 23 is assigned upper and lower guide rollers 46, 47. In the present case, these are arranged on the mold plates 23 themselves.
  • the upper guide roller 46 enters with a lower region into a slot 48 at the end of the mold plate 23. Bearing webs 49 on the upper side of the mold plate 23 carry this guide roller 46.
  • the lower guide roller 47 is also connected to the mold plate 23 in a manner not shown in detail via a pin 56.
  • the guide rollers 46, 47 are arranged in close proximity to the conveyor rollers 22, so that in this area the transfer of the blank 13 a guide through several organs is given to the mold plate 23.
  • a sheet plate 50 is located below the molding plate as part of the cutting path 20. This is provided with a longitudinal slot 51 at least in a partial area.
  • the untreated blank 13 fed to the forming station 17 is first deposited on this web plate 50. There is a small distance from the underside of the molding plate 23, namely the contact surface 35. By acting on the suction elements 36, the blank is lifted off the web plate 50 and placed on the contact surface 23.
  • a special feature relates to the removal of the blanks 13 treated by deformation.
  • a pushing element acts on a rear edge 52 of the blank 13 in question, which pushes the blank 13 on the web plate 50 (after being deposited by the form plate 23) until it is gripped by the conveyor roller 34, which cooperates with a counter roller, not shown.
  • the pushing-off element is a pushing fork 53 which can be moved back and forth. This grips the rear edge 52 of the blank with upper ends 54 and conveys this in the direction of the blanking path 20. The ends 54 enter into grooves 55 on the underside of the molding plate 23 .
