Definitions

  • the present invention relates to a method and arrangement for feeding packaging blanks erected in an erecting machine from the erection position under a form chamber in the erecting machine, where an erecting plunger inside the erected blank relinquishes the blank to an underlying delivery conveyor for further horizontal conveyance to a filling and sealing sta ⁇ tion, and where the erected blank may have a lid hingedly attached to its rear side wall, this lid being in an upright, vertical attitude as the erected blank is fed downwards to the delivery conveyor, the lid being in the same plane as the rear side wall.
  • the mechanisms In the erecting machines at present on the market there is a considerable problem with the mechanisms transferring the ready-erected blanks from the form chamber down to a convey ⁇ ing means for taking them to a filling and sealing station.
  • the transferring mechanisms at present comprise separate suction cup means, which grip the erected blank and guide it downwards from the chamber to the conveying means.
  • the object of the present invention is to obviate the dis ⁇ advantages of the already known arrangements and apparatus of the kind mentioned, and to provide a method and arrangement with apparatus for conveying the ready-erected packaging blanks from the form chamber in an erecting machine and down to a conveyor which will deliver them to a filling and seal ⁇ ing station without unnecessary operational breakdowns, even for very high machine speeds, while the arrangement and apparatus for carrying out the method is simple and reliable in the construction and disposition of its parts.
  • the advantage may also be mentioned that the downward movement of the blanks can take place at the rate required to suit the pitch of the flights of the feed con ⁇ veyor intended to take the erected blanks sideways from the erecting machine for further operations such as filling and sealing.
  • great flexibility in setting up formats, as well as reliability of operation are afforded by the inventive method arrangement.
  • FIG. 1 a schematic, perspective view (Fig. 1) and partial side view (Fig. 2) illustrate an arrangement and apparatus for carrying out the method in accordance with the invention.
  • the object of the arrange ⁇ ment and apparatus is to feed ready-erected blanks 1 from their ejection position 2 under a form chamber 3 in an erecting machine.
  • an erecting plunger 4 inside the erected blank 1, and when the latter is relinquished by the plunger 4 it is transferred to an underlying delivery conveyor 5 for horizon- tal conveyance of the erected blank 1 to an unillustrated filling and sealing station.
  • Transfer of the erected blank 1 from the form chamber 3 to the feed conveyor 5 takes place with the aid of a vertically disposed vacuum conveyor 8, which includes at least one vertically moving belt 9, the rear side wall 6 attached with upstanding lid 7 of the erected blank being urged against the belt 9 with the aid of vacuum from a vacuum box 10 included in the conveyor 8.
  • the belt 9 is implemented, inter alia, with large friction at its conveying surface, and is intended to provide controlled feed of the erected blank downwards from the form chamber 3 until the bottom 11 of the erected blank comes into contact with the upper surface 12 of the delivery conveyor 5. Substantially simultaneously with this contact the side wall 6 and attached lid 7 are automatically released from the belt 9 with the aid of cunieform means 20 on either side of the belt.
  • the delivery conveyor 5 is pro ⁇ vided with consecutive flights 13, which bear against one of the side walls 14 of the erected blank 1 for moving it in a horizontal direction.
  • the latter may include a vacuum box 21 with holes 22 in the upper surface 12 (see Fig. 2) , suction then keeping the erected blanks down on this surface.
  • the vacuum conveyor 8 is disposed with its extension in a vertical direction, its upper portion 15 in juxtaposition with the lower part of the form chamber 3, and its lower portion 16 in juxtaposition with the upper surface 12 of the conveyor 5.
  • the conveyor 8 includes a vacuum box 10.
  • At least one timing drive type of endless belt 9 has its part facing towards the erected blank extending over and along the box, which has a slit coacting with holes 17 at given spacing in the belt 9 for providing the suction urging the side wall and lid of the erected blank against the belt.
  • the slit in the vacuum box is not illustrated on the drawing.
  • the invention method of feeding erected blanks from the form chamber 3 in the erecting machine is as follows. As soon as the plunger 4 that erected the blank in the chamber 3 has relinquished it, its rear side wall 6 and attached lid 7 are sucked against the belt 9 of the vacuum conveyor 8. The erected blank 1 then moves downwards in a controlled manner until its bottom 11 comes into contact with the upper surface 12 of the delivery conveyor 5, when the erected blank is automatically released from the vacuum conveyor 8.
  • the auto ⁇ matic release is enabled either by the effect of the vacuum retaining the erected blank being less than the lateral dis ⁇ placement force exercised by the delivery conveyor 5, or with the aid of cunieform members 20 disposed on either side of the belt 9 at the lower portion 16 of the conveyor 8.
  • the erected blank 1 After its release from the conveyor 8 the erected blank 1 is fed to a filling and sealing station, not illustrated on the draw ⁇ ing, by the flights 13 of the conveyor 5 in combination with sucking the bottom 11 of the erected blank 1 against the upper surface 12 of this conveyor, or solely by suction grip on the bottoms of the erected blanks.

Abstract

L'invention se rapporte à un procédé et un agencement d'alimentation en ébauches (1) d'emballage, montées dans un appareil de montage, à partir d'une position d'éjection (22) sous une chambre de formage (3) située dans l'appareil. Dans cette position, un piston de montage (4), qui se trouve à l'intérieur de l'ébauche, libère celle-ci afin de la transférer vers un transporteur d'alimentation sous-jacente (5) qui va la transporter horizontalement vers un poste de remplissage et de scellement. Pratiquement au moment même où elle est libérée, l'ébauche montée (1) est saisie par un transporteur (8) à vide, connu en soi, qui comprend au moins une bande (9) à déplacement vertical. Une paroi latérale (6), et, éventuellement, un couvercle (7) fixé à la verticale à la paroi de l'ébauche, sont poussés contre la bande afin d'être déplacés de manière régulée vers le bas, jusqu'à ce que le fond (11) de l'ébauche entre en contact avec la surface supérieure (12) du transporteur d'alimentation (5) presque en même temps que l'ébauche est automatiquement libérée du transporteur (8) à vide, afin d'être transportée à l'horizontale par le transporteur (5) vers un poste de remplissage et de scellement.
