Definitions

  • the invention relates to a break off system for paper cutting machines, which allows cutting perforated paper bags in desired dimensions without forming camber.
  • the purpose of the invention is to provide a break off system for paper bag cutting machines, which eliminates the prior art drawbacks and performs quick cutting operation.
  • Purpose of the invention is to allow cutting paper bags in desired lengths, by means of the mandrel break off system.
  • Another purpose of the invention is to provide proper paper bag cutting operation without the need of an additional part, by means of the mandrel break off system.
  • Figure 1 provides a perspective view of the paper bag production line.
  • Figure 2 provides a top perspective view of the paper cutting machine. On this figure, the break off system is marked as detail A.
  • Figure 3 provides a bottom perspective view of the paper cutting machine. On this figure, the break off system is marked as detail A.
  • Figure 4 is a top view of detail A in the break off system according to the present application.
  • Figure- 5 is a bottom view of detail A in the break off system according to the present application.
  • Figure 6 is a side section view of the paper cutting machine. On this figure, the components of the break off system are marked as detail B.
  • Figure 7 is a view of detail B in the break off system according to the present application.
  • Figure 1 provides a perspective view of the paper bag production line. If it is desired to provide the paper bag with any press thereon, then the paper is transferred to a press unit (B) following the winding-unwinding unit (A).
  • the invention relates to a break off system (40) to be used in paper cutting machines (50) found in the breaking off unit (E) to allow cutting perforated paper bags in desired sizes without forming camber.
  • FIG. 2 provides a top perspective view of the paper cutting machine (50).
  • Figure 3 provides a bottom perspective view of the paper cutting machine (50).
  • the break off system (40) is marked as detail A.
  • Said break off system (40) comprises, in its most general form, a moving mandrel (20), which applies force on perforated papers to ensure compression during breaking off, carries the perforated paper by means of the rotational motion, and moves on the vertical plane, a fixed mandrel (21 ), which applies force on perforated papers to ensure compression during breaking off, and carries the perforated paper by means of the rotational motion, a lower breaking off mandrel (22) ensuring cutting of perforated papers by means of the rotational motion thereof, at least one breaking off surface (23), which is positioned on the lower breaking off mandrel (22), and breaks off perforated papers by means of increasing friction, a lower breaking off mandrel (24) ensuring cutting of perforated papers by means of the rotational motion thereof, a bump formed
  • Figures 4 and 5 are top and bottom views of detail A in the break off system (40) according to the present application.
  • the moving mandrel (20) is found below and the fixed mandrel (21 ) is found above.
  • these structures can also be preferably configured such that the moving mandrel (20) would be above and the fixed mandrel (21 ) would be below.
  • the way of operation of the system is as follows: During paper bag production; perforated pressed papers which come from moulding is fed into the mandrel system (40) of the invention in order to ensure breaking off operation, by means of the lower pulling mandrel (10) and the upper pulling mandrel (1 1 ).
  • the perforated paper advances between the fixed mandrel (21 ) and the moving mandrel (20), by means of the fixed mandrel (21 ) and the rotating motion provided by the moving mandrel (20), and reaches below the upper break off mandrel (22).
  • the moving mandrel (20) moves upward on the vertical plane within a bearing (34). Said movement of the moving mandrel (20) is ensured by means of a motion mechanism (33) that operates with the power provided by a drive component (30). Due to paper basis weight difference, the rotation adjuster (8) is rotated by manual adjustment, and the pressure is increased or reduced by moving the moving mandrel (20) in the vertical plane by means of the motion transmission component (7) and the motion mechanism (33). If the basis weight of the paper is high, then the pressure is reduced, and if the basis weight of the paper is low, then the pressure is increased.
  • the perforated paper is broken off (torn) at the perforation area due to the difference of rotation of the lower breaking off mandrel (24) and the upper breaking off mandrel (22).
  • the breaking off surfaces (23) found on the upper breaking off mandrel (22) contact the bump found on the lower breaking off mandrel (24), and said bump supports breaking off by providing resistance on the perforated part in between, the perforated part can be separated (broken off) without formation of a camber.
  • FIG 6 is a side section view of the paper cutting machine (50). All the details of the paper cutting machine (50) are given on this figure.
  • the broken off paper bag is transferred to the next operation via a conveyor (60) in order to apply adhesive at the tip thereof and be folded. While the paper advances on the conveyor (60), the adhesive is applied by means of an adhesive application system (70) and simultaneously, folding operation is performed on a drum (80). After the adhesive is applied and the paper bag is folded, it is stacked on the collection table (90).
  • Figure 7 is a view of detail B in the break off system according to the present application.

Abstract

L'invention concerne un système de déchirure (40) pour massicots (50), comportant, dans sa forme la plus générale, un mandrin mobile (20), qui applique une force sur des papiers perforés pour assurer une compression pendant la déchirure, achemine le papier perforé au moyen d'un mouvement de rotation, et se déplace sur le plan vertical, un mandrin fixe (21), qui applique une force sur les papiers perforés pour assurer une compression pendant la déchirure, et achemine le papier perforé au moyen du mouvement de rotation, un mandrin de déchirure inférieur (22) assurant la découpe des papiers perforés au moyen de son mouvement de rotation, au moins une surface de déchirure (23), qui est placée sur le mandrin de déchirure inférieur (22), et déchire les papiers perforés au moyen d'une augmentation du frottement, un mandrin de déchirure inférieur (24) assurant la découpe des papiers perforés au moyen de son mouvement de rotation, un bossage formé sur ledit mandrin de déchirure inférieur (24), un mécanisme de mise en mouvement (33) fournissant audit mandrin mobile (20) le mouvement de rotation et le mouvement requis pour la compression dans le plan vertical, un palier (34) permettant le mouvement dudit mandrin mobile (20) dans le plan vertical, un dispositif de réglage de rotation (31) ajustant la pression que le mandrin mobile (20) applique sur le mandrin de déchirure (22) en fonction du grammage du papier, un élément de transmission (32) permettant la transmission du mouvement réalisé par le dispositif de réglage de rotation (31) au mécanisme de mise en mouvement (33), et au moins un élément d'entraînement (30) fournissant l'énergie requise audit système de mandrin (40).
