Definitions

  • the present invention relates to a film removal device for the packaging film in a packaging machine as described in the preamble of claim 1.
  • a driven foil feed roller pair which is controlled for the conveyance of precisely measured film sections or lengths.
  • These are real measuring and conveyor rollers, which have a servo motor are driven. Because of its leading function, the servo motor also referred to as a "master" motor.
  • the film is placed over a, from format shoulder and format tube formed part of the format where the flat film is formed into a tube which spans the format tube.
  • driven film take-off belts - which is the pair of film take-off belts form - the film tube is conveyed along the format tube.
  • the general task is to ensure that the packaging film between the film feed roller pair - which also performs a measuring function - and the pair of film removal rollers, i.e. along the format tube, always remains taut and does not form folds. Wrinkling namely means the manufacture of bags that are discarded as unusable need to be closed as they cannot be closed properly.
  • Fig. 1 those occurring in the present invention are purely schematic Working elements of a bag packaging machine shown. Not everyone else necessary elements (e.g. the frame of the machine, the closing tools, etc.) have been deliberately omitted so as not to burden the presentation unnecessarily.
  • the present application is one of six filed simultaneously Registrations by the same applicant covering the different aspects of a show modern bag packaging machine and which used to help can be obtained in order to obtain an overall representation of such a machine.
  • Fig. 1 denotes the roll with the packaging film, while 2 the Foil itself is called.
  • the film roll 1 is mounted on an axis 3 and rotates freely, but maybe slightly braked, on the same.
  • 4 is a so-called "Foil storage” called, which can have different shapes and in Case shown from a pivotable lever 5 with two pulleys 6 and out there are three deflection rollers 7 mounted in the frame.
  • the lever 5 is in two different positions are drawn to show how, by its pivoting around the axis 8, the path to be described by the film 2 can change. This Changing the length of the path serves to gradually promote the slide through the following conveyor elements (see later) compared to the continuous To compensate for funding by the film roll 1.
  • a driven Foil feed roller pair shown, which consists of a driven roller 10 and consists of an entrained pressure roller 11.
  • the pair of rollers 9 will According to the invention with a servo motor 12 (purely schematically in the drawing with a square) for the controlled conveyance of precise film sections driven.
  • a servo motor 12 (purely schematically in the drawing with a square) for the controlled conveyance of precise film sections driven.
  • the control of the servo motor 12 can e.g. as in the parallel application entitled "Web Edge Control Device for film processing machines, in particular packaging machines ".
  • film 2 follows in the direction of transport Format shoulder 13 and format tube 14 existing format part 15, the function of which Conversion of the flat film 2 in a film tube around the tube 14 is.
  • the product to be filled is filled into the film tube by a funnel 16, while the bag is sealed with means not shown, i.e. is closed.
  • the advance of the film 2 along the format tube 14 is by means of two (in Fig. 1, however only one of them visible) pressed against the format tube 14, driven Film take-off belts 17, which together form a pair of film take-off belts 18, accomplished. All of this is state of the art and is used in many bag packaging machines carried out in practice.
  • the invention is now characterized in that the film feed roller pair 9 with a servo motor 12 for a precise section length with precise, highly dynamic Drain profile is driven - which means that the servomotor 12 is a has low reaction inertia - and that the pair of film straps 18 with at least one torque-controlled motor 19 is driven.
  • each of the two, the pair of film straps 18th forming film take-off belt 17 driven by a torque-controlled motor 19 is, of course, in this case, the two motors 19 strict to each other have to run synchronously.
  • the only decisive factor in the sense of the invention is the fact that the torque-controlled Motor 19, or the two torque-controlled motors 19, is able or are, the trigger belt 17 of the pair of film trigger belt 18 opposite the Packaging film 2 always in advance, regardless of the feed height of the Feed roller pair 9 to get and thus - without compared to the film 2 slide - continuously pull on them.
  • the film take-off belt 17 which is constantly be pressed against the format tube 14 - in such a way that they are not opposite the Slide 2 can slide - exert a constant pull on the packaging film 2, and even when the film take-off belt 17 is at a standstill and even if, like provided according to a further embodiment of the invention, the pair of film straps 18 is currently in an upward movement with respect to the tube 14 located.
  • the The tensile force of the at least one motor 19 of the pair of film take-off belts 18 is greater than the friction of the packaging film 2 on the format shoulder 13, summed up with the Friction of the film take-off belt 17 and added up with a certain power reserve - which is the tension force of the film 2 when the film feed roller pair 9 stands still, corresponds.
  • the choice of the tensile force of the torque-controlled motor 19 thus depends on the existing friction between slide 2 and sliding surfaces (on the Shoulder 13 and on the format tube 14) and between film 2 and the film take-off belt 17 and can be done with a suitable choice of materials and properties the slide 2 can be influenced. It is up to the specialist to determine the tractive force of the at least one motor 19 based on practical experience and more suitable Determine measurements so that the inventive conditions - namely the permanent Tension on the film without sliding the film take-off belt 17 - can be achieved.
  • the torque-controlled motor 19 must run ahead of motor 12 and never run behind, i.e. stand back. By the requirement of this preferred variant always fulfills this condition.
