Definitions

  • the present invention relates to a web edge control device for film processing Machines that work in time and after precise film length measurements are controlled as described in the preamble of claim 1.
  • the film processing machines are used today in different sectors of the Technology applied, e.g. in the paper industry, in the packaging industry etc. Such machines often include about certain functions of the machine, such as. to cut or fold a film into sections of equal length, or one to position moving film in certain positions, etc., according to exact Control film length sections. This is very often the case with packaging machines used where preprinted foils are used, where the preprint must always appear in exactly the same place. In so-called bag packaging machines it is also about making bags of constant size or length.
  • the object of the present invention is to solve the problems mentioned by the displacement of the film edge disadvantages caused a simple, cheap and propose a safe solution, which in particular relies on controlling the situation can dispense with the film roll on its axis.
  • the edge position adjustment device is a rigid unit with the Forms print mark reader, it is now sufficient to provide that the edge position adjustment device the lateral adjustments of the film edge, by hand or automatically controlled, can follow to achieve that automatically the print mark reader is always placed correctly in relation to the print mark, which always means ideal conditions are given for reading the print marks. Because the edge position adjustment device and the print mark reader are very close together and in common are moved laterally to follow the migration of the edge Adjustment of the position of the print mark without any delay compared to the detection the displacement of the edge, which however can be the case if one the determination of the peripheral position at a location, i.e. removed from the film roll Place, makes.
  • Fig. 1 is an application of the inventive device in a bag packaging machine shown.
  • inventive Furniture can also be used on other production machines where a sheet of paper, plastic or metal is processed, provided that the Problem of lateral migration of the film is present and inventive Way can be solved.
  • Fig. 1 you can see, referred to in the transport direction of the packaging film, with 1 the film roll, with 2 a film storage made of dancer arms, with 3 a Foil conveyor pair 3 formed from two rollers 4 and 5.
  • Foil conveyor pair 3 delivers measured film sections and is used by the inventive web edge control device controlled. It is driven with a servo motor, not shown.
  • the so-called cross-locking device is also designated, which has the task of the hose after it has passed through the funnel 14 with the Filling product was filled and by the longitudinal closure device, not shown was closed with a longitudinal seam for its closure, as a finished bag to seal and separate from the hose.
  • A is used for the separation operation Knife 15.
  • FIGS. 2 and 3 In order to explain the invention in more detail, FIGS. 2 and 3 must now be used.
  • the web edge control device is in its structural details shown, it should be noted that in Fig. 3 the device, from purely illustrative Reasons shown in the opened position opposite the film web 9 is.
  • the film edge is shown at 16.
  • the edge 16 there are printing marks 17 attached to each other at regular intervals.
  • a print mark reader which in any way, e.g. optically with colored brands or capacitive with magnetic signs etc., the mark 17 can determine.
  • two sensors are designated, which with corresponding elements, preferably optical elements (but other elements are also conceivable) on the Presence - namely sensor 19 - or the absence - namely sensor 20-der Film web 9 react.
  • the edge position adjustment device 6 can follow the lateral displacement of the film web 16, this function of By hand, e.g. a handwheel, as will be explained later, or automatically, by means of a separate servo motor, and that the print mark reader 18 rigidly coupled to a unit with the edge position adjustment device 6 is.
  • the print mark reader 18 is always opposite the film edge 16 is automatically placed correctly and is therefore always able to print mark 17 reliably determine and trigger the corresponding function of the machine.
  • the film roll 1 can in principle assume any lateral position and also the width tolerances the slide doesn't matter.
  • the Edge position adjustment device 6 and the print mark reader 18 on a common, carrier 21, which is laterally adjustable and displaceable relative to the film edge 16 are fixed.
  • the carrier 21 can e.g. the shape of an adjustable and removable plate exhibit.
  • the one carrying the edge position adjustment device 6 and the print mark reader 18 Carrier 21 is equipped with a threaded spindle 22, which is equipped with a handwheel 23 can be operated in the sense of a displacement of the carrier 21 in a lateral direction, or in the opposite direction, opposite the film edge 16.
  • a threaded spindle 22 which is equipped with a handwheel 23 can be operated in the sense of a displacement of the carrier 21 in a lateral direction, or in the opposite direction, opposite the film edge 16.
  • an acoustic or optical signal transmitter (not shown in the figures) is present is which receives signals from the edge position adjusting device 6 and accordingly responding. This measure is generally intended to help staff.
  • the lateral displacement of the film edge 16 outside a certain tolerance limit by one of the two sensors 19, 20 of the edge position adjusting device 6 is determined and that subsequently an appropriate acoustic for the staff or optical signal is triggered by the signal generator.
  • This solution is also a simple variant of the invention, which the constant presence of the operating personnel conditionally. But it has the advantage of simplicity and a price advantage compared to other solutions.
  • the adjustment of the position of the edge position adjusting device 6 and the print mark reader 18 automatically follow the lateral migration of the film edge.
  • the carrier 21 with a - in the figures not shown - motorized drive for its displacement in a lateral direction or is equipped in the opposite direction to the film edge and that the drive automatically for a movement in or out through the edge position adjustment device is controlled.
  • the Sensors 19 and 20 of the edge position adjustment device 6 in the transverse direction of the film web have a mutual distance a (see FIG. 3) of 0.5 ⁇ 2 mm, preferably 1 mm. Experience has shown that this results in sufficient path control precision.
  • the web edge control device to be applied to a bag packaging machine.
  • the machine contains a pair of feed rollers 3, one from format shoulder 8, Format tube 10 and film take-off belt 11 formed format part, as well as a cutting apparatus 14 for separating the film web 9 after the formation and filling of the Bag.
  • a cutting apparatus 14 for separating the film web 9 after the formation and filling of the Bag.
