Definitions

  • the invention relates to a device for molding or preforming blanks for packs, in particular folding boxes with rounded or polygonal longitudinal edges, the blanks being able to be fed to a molding station with at least one molding unit consisting of a molding plate with shaping longitudinal edges and movable molding tools, in particular elongated molding rollers the movable molds can be moved along edge regions of the mold plate while deforming the blank, in particular from the underside of the mold plate to the top.
  • Folding boxes - also called hinge-lid packs - are a widely used form of packaging for cigarettes.
  • Hinged boxes for cigarettes have recently been increasingly used, the upright longitudinal edges of which are rounded, beveled or polygonal.
  • the manufacture of such packs requires pretreatment of the blanks, namely preforming them in the area of the longitudinal edges.
  • US 4,708,704 shows and describes an example of a device for shaping or preforming blanks for hinged boxes.
  • the present invention relates to a further development or improvement of the device according to US Pat. No. 4,708,704 or similar shaping devices for blanks.
  • the invention has for its object to provide a device of the type mentioned in such a way that a higher performance is achieved when molding or preforming the blanks.
  • the device according to the invention is characterized in that the movable molds, in particular mold rollers, can be lifted sideways from the mold plate after execution of a shaping movement cycle and can be returned to the starting position along a movement path running at a distance from the mold plate.
  • the shaping tools namely shaping rollers
  • the shaping tools perform an up and down movement in the region of the lateral rounded or trapezoidal shaping edges of the shaping plate
  • the shaping tools are moved out of the area of the shaping plate after completion of a shaping work cycle and with a clear Distance from this moved back to the (lower) starting position. This saves considerable time. If the form rollers are lifted off the mold plate in the upper position, the blank processed by preforming can already be transported away and a subsequent, unprocessed blank can be brought into position. When the molding tools have reached the starting position, the blank to be machined can already have reached the required position on the underside of the molding plate.
  • the advantage is a significantly reduced cycle time of the forming station.
  • a mechanical gear for actuating the shaping rollers, said gear mechanism being pivotable and opening and closing there is movably mounted angle lever for the forming rollers and two actuating gears acting in a coordinated manner.
  • unfolded blanks 14 on the underside are taken from a customary blank magazine 13 one after the other.
  • a dispenser 15 which is customary in practice is used for this.
  • the folding turret 17 can be designed in the manner described in US Pat. No. 4,084,393.
  • a forming station 18 is arranged upstream of the folding turret 17 in the region of the cutting path 16. In the area of the longitudinal edges 11, 12 are preformed in the area of the otherwise flat, unfolded blank in the sense of a rounding. The preformed blank is then fed to the folding turret 17 on the blank web 16 and processed in a conventional manner.
  • the molding station 18 is equipped with at least one molding unit 19. This consists of a fixed mold, namely a mold plate 20 and two movable molds, namely mold rollers 21 and 22.
  • the mold plate 20 is formed with lateral, longitudinally extending mold edges 23, 24 which correspond to the contour of the longitudinal edge 11, 12 to be produced. In the present case, the shape edges 23, 24 are therefore round.
  • the molding plate 20 is adapted to the dimensions of the blank 14. Lateral areas of the same protrude laterally beyond the mold plate 20 in the starting position. These are the side flaps 25, 26 which are customary in a blank 14 for folding boxes 10. These are pressed against the mold edges 23, 24 during the preforming of the blank, so that in the region between the side flaps 25 and 26 on the one hand and a central region of the Blank 14, the rounded longitudinal edges 11 are formed.
  • the blank 14 is conveyed on the blank web 16 by transport rollers 27 into the molding station 18, specifically in such a way that the blank 14 lies below the molding plate 20.
  • the blank is pressed against the underside of the molding plate 20 by suitable holding members, in particular suction members (not shown).
  • the blank 14 assumes the position shown in FIGS. 2 and 3.
  • 20 conveyor disks 43 are assigned to the mold plate. In the present case, these are arranged on the molding plate 20 itself.
  • the conveyor disk 43 enters with a lower region into a longitudinal slot 44 at the end of the molding plate 20.
  • the conveyor disc 43 acts with an additional, arranged below the mold plate 20 Conveyor disc (not shown) together.
  • One of the conveyor disks 43 is arranged in close proximity to the transport rollers 27. Thus, a guide through several organs is provided for the transfer of the blank 14 to the mold plate 20.
  • the form rollers 21, 22 are effective. These are in a starting position below the molding plate 20 and also below the blank 14.
  • the molding rollers 21, 22 are now along a first circular movement path 28 along the contour of the molding edges 23, taking the protruding parts of the blank 14 into an upper, in Fig. 3 dash-dotted position moves.
  • the areas of the longitudinal edges 11, 12 are placed under pressure on the mold edges 23, 24.
  • the shaping rollers 21, 22 return to the starting position, namely below the shaping plate 20.
  • the shaping plates are moved along a movement path 29. This is chosen so that the forming rollers 21, 22 move sideways from the upper end position and then downwards and finally back to the starting position.
  • the sideways movement of the shaping rollers 21, 22 causes them to come completely out of the area of the shaping plate 20 or of the blank 14.
  • the deformed blank 14 can be removed and a new, flat blank 14 can be fed. This can already be in the working position according to FIG. 2 when the forming rolls 21, 22 reach the starting position (solid lines in FIG. 3).
  • the movement of the forming rollers 21, 22 along the differently designed movement paths 28, 29 is achieved by a special gear.
  • the shaping rollers 21, 22 are arranged at the upper ends of an angle lever 30.
  • the shaping rollers 21, 22 are arranged at the upper, free end of an upright leg 31.
  • a lifting drive 33 acts on a leg 32 which is oriented horizontally in the starting position. In the present case, this consists of a link 34 which can be moved up and down and which is articulated the free end of the leg 32 on the one hand and with an actuating lever 35 on the other hand. The latter is moved up and down in the vertical plane in a pivoting sense.
  • crank 36 with a crank arm 37.
  • the crank 36 is concealed behind the angle lever 30.
  • This is connected to the crank arm 37 in the region of a pivot bearing 38, the pivot bearing 38 being in the region of the connection of the two legs 31, 32.
  • a stationary crank bearing 39 lies above it.
  • crank 36 The transmission formed by the crank 36 is primarily responsible for the sideways movements of the forming rolls 21, 22. This movement is superimposed on the upward movement of the link 34.
  • the crank arm 37 executes a reciprocating movement in the vertical plane, which is indicated by an arrow 40.
  • the connection point between the handlebar 34 and the leg 32, namely a pivot bearing 41, moves along a complex movement path 42 which has approximately the shape of an "8".
