  • the feed 3 further comprises a guide wall 31, 33 arranged at a respective lateral end 27, 29 of the deflection roller 5, which is designed and shaped to deflect the packaging material web in the direction of the deflection roller 5 and thus into the interior of the packaging material production machine 1.
  • the top view in Figure 2 essentially shows the compactness of the packaging material production machine and its housing contour.
  • the packaging material production machine has its widest area in the area of the feed 3 and tapers from there increasingly towards the delivery device 11.
  • the guide wall 33 protrudes against the conveying direction of the packaging material web over the extent of the deflection roller 5.
  • the guide wall 31, 33 comprises guide surfaces 35, 37 which are convex in the direction of the deflection roller 5 and are used for the continuous feeding and deflection of the packaging material web towards the deflection roller 5 and thus into the interior of the packaging material production machine 1.
  • Figure 3 shows a side view of the packaging material production machine 1. From this it can essentially be seen that the guide wall 31, 33 covers the deflection roller 5. This is therefore arranged in the slipstream of the deflection roller 31, 33. It can also be seen that the guide wall 31, 33 protrudes over the roller in the opposite direction to the conveying direction and also protrudes in a direction transverse to it, in particular in the vertical direction, over the extension of the deflection roller 5, so that the guide wall can reliably deflect the packaging material web particularly flexibly and independently of the position of the packaging material web to be conveyed.
  • the guide 3 comprises a pair of rollers 39, 41 forming the deflection roller 5, which are mounted so as to rotate freely, for example, as indicated by the rotation centers R3g and R41.
  • These can, as can be seen by way of example in Figure 3, be arranged one above the other in the vertical direction or can be arranged in relation to one another in such a way that the lower roller 41 in relation to the vertical direction protrudes relative to the roller 39 in relation to the conveying direction of the packaging material web.
  • Figure 4 shows an exemplary embodiment of a packaging material production machine according to the invention in which the feed 3 has, instead of rotatably mounted rollers, rigid guide surfaces 43, 45 which form a conveying gap 47 between them through which the packaging material web can reach the interior of the packaging material production machine 1.
  • Figures 5 and 6 show further exemplary embodiments of packaging material production machines according to the invention, which differ from one another with regard to the feed 3.
  • the difference between the two embodiments lies in the dimensioning of the lateral guide walls 31, 33, which are significantly smaller in Figure 6 than in Figure 5.
  • Both embodiments have in common that the guide wall 31, 33 forms a lateral end section of the rollers 39, 41 and in particular a section between a lateral housing wall of the Packaging material production machine on which the rollers 39, 41 are mounted, and a bearing gap at the lateral front end of the rollers 39, 41 is covered by the guide wall. This can prevent packaging material from becoming tangled or lost in the area of the bearing gap.
  • Figures 7 to 10 show various designs and views of a packaging material production machine in which the cover part 15 is omitted.
  • This shows another important aspect of the present invention, according to which all functional components of the packaging material production machine 1 are arranged or fastened to the base part 17 and are supported by it.
  • Lateral boundary walls 49, 51 are arranged downstream of the feed 3 in the conveying direction, which serve to additionally guide the packaging material web.
  • funnel wall sections 53, 55 are provided, which, according to Figure 7, are arranged at a distance from the boundary walls 51, 49 in the conveying direction, but can also merge into them or be formed in one piece with them.
  • the funnel wall sections 53, 55 delimit a conveying path between them, which increasingly and in particular continuously tapers or reduces in size in order to finally feed the packaging material to be processed centrally to the forming device 9.
  • the forming device 9 has a pair of conveyor wheels 57, 58, of which one conveyor wheel 57 is visible in Figure 7.
  • the conveyor wheel 57 is driven by a motor-gear arrangement 59 in order to actively convey the packaging material and in particular to remove it from the packaging material supply.
  • a funnel cover 61 is also provided, which limits the conveying path upwards opposite the base part 17.
  • the funnel cover 61 can also extend against the conveying direction up to approximately the level of the feed 3.
  • the design according to Figure 8 differs from the design according to Figure 7 with regard to the feed 3.
  • the feed also has a pair of rollers, whereby the lower roller 41 is offset against the conveying direction in relation to the upper roller 39. This is indicated by a line between a vertical V and a connecting line A between the rotation axes R39 and R41 is indicated.
  • the guide wall 31, 33 according to Figure 8 is equipped with a deflection funnel wall section 63, 65, which ensures that packaging material passing laterally past the feed 3 is nevertheless guided to the roller pair 39, 41.
  • a pair of in particular free-running conveyor rollers 67, 69 with a vertical axis of rotation are provided, on which the packaging material is additionally diverted in a concentrated manner towards the center.
  • Figure 9 shows a rear view of the embodiment of the packaging material manufacturing machine according to Figure 8 and shows the second conveyor wheel 58 of the conveyor wheel pair of the forming device 9.
  • the delivery device 11 comprises two shaft walls 71, 73 which are essentially perpendicular to the conveying direction and whose leading edges are shaped to form tear-off prongs or teeth 13.
  • Figure 10 belongs to the design of the packaging material production machine according to Figures 8 and 9 and shows the conveyor wheels 57, 58 of the forming device 9 rolling against each other. Due to the rolling contact, which is indicated by the reference number 75, packaging material can be reliably and constantly conveyed through the packaging material production machine and thus packaging material products can be manufactured which can finally be removed via the discharge device 11.
  • FIG 11 shows schematically the conveying path, which is indicated by reference number 77, of the packaging material web through the packaging material manufacturing machine 1.
  • a further funnel section is formed from two opposite housing walls 79, 81, which form a narrowed channel section by forming a shoulder 83, 85 each. This creates a reliable transfer of the packaging material web to the hopper walls 53, 55 is ensured.
  • FIG 12 shows a schematic horizontal configuration of the packaging material production machine 1, in which a horizontal line is indicated by the operating symbol H.
  • the feed 3 is arranged in relation to the remaining components, in particular the forming device 9 and in particular its conveyor wheel 57, 58, such that an angle ß results between the horizontal H and a conveyor path line F indicating the conveying direction.
  • the packaging material web is conveyed towards the lower deflection roller and partially deflected by it before the packaging material leaves the roller 41 at a contact end point 87.
  • a connecting line between the contact end point 87 and a rotation center Rg of the deflection device is at an angle ß in the range of more than 0° to a maximum of 10° relative to the horizontal H.
  • a tip of the at least one tear-off tooth 13 is arranged to project inwards relative to an outer contour of the housing 15.
  • each tear-off tooth 13 including its tip is arranged flush with the outer contour of the housing 15 and/or does not protrude outwards beyond the silhouette of the housing 15.
  • the tear-off teeth 13 project by a few millimetres, preferably by 2, 3 or 5 millimetres including the respective tear-off tooth tip, against the conveying direction F into the interior of the housing 15, so that the manual handling of the packaging material production machine 1 is improved.
  • the tearing and/or cutting device has two rows of tearing teeth 13 spaced apart from one another.
  • the clear width between the rows of tearing teeth 13 is smaller than the clear width of the housing opening, which corresponds to the tearing and cutting device or to the dispensing device 11.
  • the tips of the tearing teeth 13 thus protrude into the housing interior, while on the other hand the packaging material is safely grasped and severed by the tear-off teeth 13 even if the strand of packaging material is pulled very strongly to the side at an angle of more than 70 degrees and obliquely with respect to the conveying direction F.
  • the packaging material production machine 1 Because the essential basic elements of the packaging material production machine 1 are designed as sheet metal elements, it is possible to use different materials. According to an exemplary embodiment of the packaging material production machine 1, steel components are used. These can be connected to one another in a material and/or form-fitting manner and offer the advantage of superior robustness while optimizing the wall thicknesses. According to another embodiment of the packaging material production machine 1, aluminum components are used and offer the advantage of weight optimization. According to another embodiment of the packaging material production machine 1, plastic components are used, which offer advantages such as production optimization when they are thermally formed or molded. According to another conceivable embodiment of a packaging material manufacturing machine 1, different materials are used which, in contrast to the material-locking joining methods, are now joined to one another according to a positive-locking and/or material-locking (adhesive) joining method.
  • the guide wall 31, 33, as well as the boundary wall 49, 51 and the funnel wall section 53, 55 are connected to one another and/or form a one-piece molded part or form a molded part composed of several parts. Overall, this improves the stability of the packaging material manufacturing machine 1.
