Definitions

  • the invention relates to a device for producing blanks for collars in hinged boxes with rounded or polygonal longitudinal edges, the blanks being able to be separated one after the other from a material web and fed to a molding station in which the collar between molds during a standstill phase with the formation of rounded or polygonal edges a collar front wall and collar side tabs is deformable.
  • a collar is part of a hinged box - also called a hinge-lid pack.
  • This type of pack is widely used for cigarettes.
  • Such a folding box usually consists of a box part and a lid. The latter is pivotally connected to the box part in the region of a rear wall.
  • a collar consisting of a collar front wall and angled collar side tabs is arranged, which partially protrudes from the box part and is enclosed in the closed position by the lid.
  • Hinged boxes with rounded, beveled or polygonal longitudinal edges have recently been found. In the folding boxes designed in this way, the collar must also be adapted to the geometric shape. Edges formed between the collar front wall and the collar side tabs must therefore be rounded or polygonal.
  • the invention is concerned with a further development or alternative to this known device.
  • the invention has for its object to propose measures by which the manufacture or pretreatment of the collar can be accelerated by shaping the edges without loss of quality.
  • the device according to the invention is characterized in that the blanks in the area of the molding station can be transported by a blank conveyor passing through the molding station, in particular by an endless conveyor, on the conveying path of which the blanks rest and which temporarily positions the blanks in the area of the molding tools.
  • a belt conveyor is suitable as an endless conveyor for the collar blanks.
  • the belt conveyor is driven intermittently in such a way that a longer standstill phase occurs in the area of the molding tools, in particular on a molding plate.
  • the edges are shaped by correspondingly pivoting or folding the collar side flaps using suitable shaping tools, in particular shaping rollers. The cut is then transported on by the belt conveyor.
  • the blanks are conveyed through one and the same blank conveyor through the entire forming station.
  • Holding elements acting from above fix the blanks, especially in the area of the molding plate.
  • These holding members are preferably an upper belt rotating with the belt conveyor, the lower strand of which rests as a pressure strand on the upper side of the blanks.
  • pressure elements acting against the pressure strand are provided at least in the region of the molding plate, in particular elastic pressure elements. As a result, the blank is stably positioned in the area of the molding tools.
  • the illustrated embodiment of a device is set up for processing, namely for preforming, blanks 10 for collars in hinged boxes.
  • Collars or their blanks 10 usually have a special, characteristic shape which results from the plan view in FIG. 2.
  • Such a blank 10 consists of a central collar front wall 11 and collar side flaps 12, 13 extending on both sides. In the position in a package in a folding box, the collar side flaps 12, 13 are formed at a right angle to the collar front wall 11 . This creates (upright) edges 14, 15 between the aforementioned cut parts.
  • the edges 14, 15 should be designed to be correspondingly rounded for a hinged box with rounded longitudinal edges.
  • a corresponding preforming takes place in the area of a Forming station 16 of the device.
  • the blanks 10 are separated one after the other from a continuous material web 17 made of thin cardboard.
  • the material web 17 passes through a cutting unit 18.
  • this consists of two rollers, namely a cutting roller 19 and a counter roller 20.
  • the blanks 10 separated with the characteristic contours are gripped following the cutting unit 18 by conveyor rollers 21 which are driven at the same speed as the rollers of the cutting unit 18.
  • the individual blanks 10 are taken over by acceleration rollers 22. These are driven at a noticeably higher speed than the conveyor rollers 21. As a result, the blanks are accelerated. This creates a larger distance between the successive blanks.
  • the blanks 10 are transferred from the acceleration rollers 22 to the forming station 16.
  • the blanks 10 are transported by a blank conveyor 38, in particular by an endless conveyor, namely by belt conveyors arranged in the middle. It is a lower belt conveyor 23 and an upper conveyor 24 arranged above it, which is preferably designed and dimensioned in the same or similar manner as the belt conveyor 23.
  • An upper conveyor strand 25 of the belt conveyor 23 and a lower pressure strand 26 of the upper conveyor 27 lie along the Conveyor line to each other.
  • the blanks 10 are received between the conveyor strand 25 and the pressure strand 26, with the collar front wall 11 or a part thereof.
  • the aforementioned endless conveyors are driven at the same speed as the accelerating rollers 22.
  • deflection wheels 27, 28 are arranged at a distance from the accelerating rollers 22 which is somewhat smaller than the dimension of the blanks 10 in the conveying direction. These are accordingly detected between the deflection wheels 27, 28 before they are released by the acceleration rollers 22.
  • the blanks 10 are conveyed through the forming station 16 by the blanking conveyor 38 consisting of belt conveyor 23 and top conveyor 24.
  • Belt conveyor 23 and upper conveyor 24 are driven so that in the area of molding tools there is a longer standstill phase for the blanks 10 for shaping the edges 14, 15.
  • the molding tools consist of a stationary molding plate 29 and movable molding tools, namely molding rollers 30 and 31. These work in the manner described in DE 41 02 005. To shape the edges 14, 15, they are moved sideways from an upper position and then downward, bearing against the mold plate 29 or at round mold edges 32, 33. In FIG. 3, the lower end position of the mold rollers 30, 31 is shown in broken lines.
  • the form plate 29 is provided with a central, longitudinally extending recess 34 for carrying out this processing of the blanks.
  • the conveyor run 25 of the belt conveyor 23 runs such that it is approximately flush with the form plate 29.
  • the blanks 10 should be positioned in a fixed relative position.
  • belt conveyors 23 and upper conveyors 24 are designed with a surface that has a high coefficient of friction.
  • conveyor run 25 and pressure run 26 lie against one another with increased pressure.
  • a contact pressure is exerted on the pressure strand 26, specifically by means of pressure members in the form of leaf springs 35 arranged above it.
  • the blanks 10 deformed in the manner described are moved back into an extended position during further transport, specifically by lateral guide members (not shown) on which the collar side tabs 12 slide.
  • the blanks 10, which are shaped back into an approximately flat position, are taken over by pull-off rollers 36 following the belt conveyor 23. These transfer the blanks to a cross conveyor 37 for forwarding the blanks 10 to the packaging machine, preferably in accordance with DE 41 02 005.
  • the cutting conveyor 38 consisting of belt conveyor 23 and upper conveyor 24 is driven in cycles.
  • the drive is transferred to the (larger) deflection wheels 27, 28.
  • the movement characteristic is designed so that in the present case three blanks 10 are accommodated in the area of the belt conveyor 23.
  • Each blank 10 accordingly passes through three holding positions in the area of the forming station 16 or the blanking conveyor 38.
  • the holding phase reduces the distances between the successive blanks as shown in Fig. 2.
  • the device is expediently driven by a stepping transmission which is known in principle and is commercially available.
