Definitions

  • the invention relates to a reel changer for a printing press and in particular to an automatic reel changer for a web-fed rotary printing press with the features of the preamble of claim 1.
  • a reel changer which carries a first (old) winding reel and a second (new) winding reel on a two-armed winding reel support which can be pivoted by a drive motor.
  • the old winding reel In the normal unwinding position of the winding reel support, the old winding reel is in the upper position and is driven or braked by a belt drive regulated by a control device so that a predetermined constant tension is established during unwinding.
  • the winding roll holder is swiveled so that the old winding roll is in the lower position.
  • a residual winding roller brake designed as an induction brake takes over the tension control via a further control device. In the upper position there is now a new winding roll with an adhesive tip.
  • the new roll is brought to the intended unwinding speed by means of the drive and control devices. Then the running web is pressed against the new winding roll, so that when the adhesive tip of the new winding roll runs through, the running web is glued to the new web, and the old web is separated from the new web that is now running.
  • the control of the individual steps of the winding roll change takes place by means of a computing device, to which web impulses and adhesive mark impulses are supplied by various sensors. It is assumed that each winding roll is unwound to a predetermined residual roll size, expressed as a predetermined final winding roll diameter. An automatic reel change is therefore not possible if the reel is only partially unwound. Another disadvantage is that the beginning of the path in the new roll to be clamped must be provided with an adhesive.
  • a job change often also means a change of the winding roll, since a substrate with different properties, e.g. with a different weight or format, or a completely different printing material is required. As a result, it may be necessary to replace winding rolls before they are completely unwound, and to stick winding rolls together without taking their properties into account.
  • the object of the invention is therefore to provide a reel changer in which the application of an adhesive can be automated and thus carried out at the latest possible time. Furthermore, an automatic roll change should be able to be carried out without restriction due to the properties of the successive printing material rolls and regardless of the degree of unwinding of the roll being processed.
  • the roll changer shown schematically in Fig. 1 has a two-armed roll change frame 1, which is designed to receive a first roll 2 of a web-shaped printing material to be unwound and a second roll to be unwound, the replacement roll 3, and which is pivotable on a horizontally extending axis, as Belt drive designed first drive and braking device 4 for the roll 2 being processed, a web pressing and separating device 5 for pressing the web of the roll 2 being processed against the beginning of the web of the replacement roll 3 to be subsequently unwound during the gluing process, an adhesive application device 6, a traversing device 7, which is arranged at a variable distance from the roll change frame 1 and by means of which the adhesive application device 6 can be brought into different positions, in each case a second drive and brake integrated in the respective arm of the roll change frame 1 Device 8 or 9 for driving the printing material roll clamped in as a replacement roll 3, a position feedback device 10 integrated into the respective arm of the roll change frame 1 for emitting an electrical signal when the replacement roll 3 has reached
  • the control device 11 continuously receives and ascertains signals from the evaluation device 13 which correspond to the length of the unwound web from this the current remaining length of the printing material web of the roll 2, referred to below as the remaining roll length, when the first remaining length has been reached or after an unwinding length determined by the print job has been completed, the control device 11 generates a signal which triggers the roll change.
  • the first remaining roll length is determined by the control device 11 from a second remaining roll length, taking into account the unwinding speed of the printing material web and taking into account the working speeds of the individual device parts.
  • the second remaining roll length is the length of printing material remaining on the roll being processed, in which the web being processed is to be glued to the new web and then cut off. This length is equal to the specified minimum remaining roll length.
  • the data required for this are input via the operating device 12 either manually or as a machine-readable data record.
  • the required data can be given as direct dimensions, as coded data or in another suitable manner, either on an order basis or as data for a sequence of orders.
  • the reel change essentially comprises the steps of swiveling the reel change frame 1 such that the reel 2 comes into a lower reel change frame position and at the same time the other reel 3 occupies the upper reel change frame position, applying an adhesive to the beginning of the roll 3 by means of an adhesive application device 6, whereby the beginning of the web is characterized in a manner that can be detected by the control device 11, for example by a marking element inserted into the roll, of accelerating the roll 3 to the unwinding speed, of pressing the running printing material web 14 onto the roll 3 for the purpose of adhering the web 14 of the roll 2 at the beginning of the roll 3 and the subsequent separation of the web roll 2 from the no longer running web of the roll 3.
  • the application of an adhesive takes place in the form of the spraying of adhesive by means of an adhesive spray head 6, which moves from one end of the roll to the other end of the roll over the surface to be sprayed parallel to the roll axis with the aid of a traversing device 7 containing a motor and a position detection device can be.
  • the adhesive spray head 6 is alternately switched on and off in such a way that on the previously cut and releasably fastened on the top roll position of the roll 3 web beginning of the roll 3 in cooperation with a rotation of the roll 3 by the second drive and braking device 9 an adhesive surface pattern is obtained which saves the belt course of the belt drive 4.
  • the beginning of the web of the roll 3 can also be provided with an inactive adhesive which is controlled in a controlled manner by means of an agent to be sprayed by the spray head 6 or by irradiation, e.g. with UV light.
  • the adhesive or the activating agent can already be sprayed on when the roller 3 is still in the lower position.
  • the control device 11 after generating the signal which triggers the roll change, causes the roll change frame 1 to pivot so that the replacement roll 3 comes to the upper position, and at the same time controls a drive and braking device 8 arranged on the arm of the roll change frame 1 carrying the roll 2, so that it maintaining the unwinding speed of the roll 2 takes over as soon as the roll 2 runs out of the effective range of the belt drive 4.
  • a drive and braking device 8 arranged on the arm of the roll change frame 1 carrying the roll 2, so that it maintaining the unwinding speed of the roll 2 takes over as soon as the roll 2 runs out of the effective range of the belt drive 4.
  • the roll 3 When the roll 3 is in the upper roll changer position, it is driven and arranged on the arm of the roll change frame that supports it
  • the braking device 9 is rotated until the beginning of the path of the roll 3 is in a starting position for the application of the adhesive. Then the adhesive described above is applied by means of an adhesive spray head 6.
  • the control device 11 controls the belt drive 4 so that the roll 3 is brought to the required unwinding speed.
  • a signal is output by the evaluation device 13 to the control unit 11.
  • the control device 11 controls the web pressing and separating device 5 in order to glue the running web of the roll 2 to the beginning of the web of the roll 3 and then to separate it from the now running printing material web.
