Definitions

  • the invention relates to a method for preparing a printing material web roll for the flying roll change and a device for carrying out this method.
  • Web-fed rotary printing presses such as those used in newspaper printing, have one - or usually even several - roll changers to enable uninterrupted printing by automatically attaching a new or replacement printing material web roll to a roll that is being developed and is to be replaced.
  • the beginning of the new roll can only be reliably adhered to the roll in progress if the respective new roll has been prepared in a suitable manner. As a rule, this preparation takes place manually, either with the roll already clamped in the roll changer or at a separate work station away from the printing press.
  • DE 38 11 138 A1 discloses a method for mechanically treating the end section of rolled-up paper.
  • a paper roll is clamped in a paper feed device of a paper processing machine.
  • a cutter is placed against the peripheral surface of the paper roll and move across to cut several paper turns as a scrap.
  • the committee is taken up by a reception center.
  • Two knives located on either side of the paper end section are moved transversely to the center while the paper is rewound to form a V-cut.
  • Glue is applied along the paper cutting edge.
  • the paper end is wound back onto the paper roll. The procedure can be performed while the machine is running.
  • the rolls prepared according to the known methods for preparing a printing material web roll for the flying roll change partly have a complex geometry of the start edge of the web and a correspondingly complex geometry of the adhesive pattern for the adhesive bonding.
  • stickers or adhesive strips can only be applied with a correspondingly high outlay.
  • mechanical and in particular automatic preparation of a printing material web roll is only possible to a limited extent and only with a correspondingly high outlay on equipment.
  • the invention has for its object to prepare a substrate roll for the flying roll change so that in addition to the advantage of a simple geometry of the web start of the substrate roll, and thus a simple geometry of the adhesive application, the possibility is given with other adhesives than stickers or adhesive strips get along, and that a high level of security against unintentional detachment of the web start of the reel is guaranteed during the fast run in the reel changer.
  • FIG. 1 shows a schematic illustration of a roll changer with a device according to the invention for preparing a printing material web roll.
  • the detachment of the outer, damaged or deformed layers of the roller 4, which is generally required, is carried out by hand or by means of a device specially designed for this purpose, but this is not of importance for the present invention and is therefore not considered further here.
  • "preparation” is understood only to mean cutting a leading edge of the web, creating a predetermined breaking line or tear line, and applying a holding adhesive and a connecting adhesive.
  • the adhesive is applied so that the beginning of the web can be glued to the outermost layer of the web roll to be wound.
  • the connecting adhesive is applied in such a way that it is possible to glue the printing material web to be replaced to the new printing material web with undiminished processing.
  • a roll 3 of web-shaped printing material which is being developed and a new roll 4 of web-shaped printing material which is provided as a replacement roll are clamped onto a roll changer frame 1 with swivel frame 2 which is known per se.
  • a device designated overall by reference number 5, which is described in more detail below, is attached to the roll change frame 1 in such a way that it can be brought up to the new roll 4 in preparation for this. However, it can also be designed as a device which can be moved freely with respect to the roll change frame 1. To carry out the roll preparation, the movable device 5 is brought into a position which is fixed in relation to the roll change frame 1.
  • FIG. 2 shows a schematic illustration of a first device according to the invention for preparing a printing material web roll 4, from which a web 41 is to be unwound, in a first way according to the invention.
  • the position of the web 41 is shown as follows: during the cutting and perforating process, it has the position shown in broken lines and identified by the reference number 41a, while during the application of the adhesive it has the position shown by the solid line and indicated by the reference number 41 .
  • a base plate 6 of the device 5 has an upper surface 61 on which the web 41 of the new roll 4 to be prepared rests during the adhesive tip preparation process.
  • a knife bar 7 is embedded in the surface 61 transversely to the unwinding direction of the new roll 4 so that only the cutting edges of a cutting knife 8 and a perforating knife 9 protrude from the surface 61.
  • the cutting knife 8 and the perforating knife 9 are arranged on the cutter bar 7 at a distance a (see FIG. 3) from one another and parallel to one another.
  • a pressing device 10 is arranged above the cutter bar 7 and both on the cutter bar 7 and movable along it, in a manner known per se and therefore not shown in detail.
  • the pressing device 10 has an elastic roller 11, for example a rubber roller.
  • the base plate 6 has an adhesive application plate 12 which is flush with the surface 61 and has an upper surface 121.
  • the surface 121 is provided with a holding adhesive groove 13, the width of which is preferably smaller, but in no case greater than the distance dimension a.
  • a pressure roller 14 can be lowered onto the holding adhesive groove 13 and can be moved along it.
  • the width of the pressure roller 14 is smaller than the width of the holding adhesive groove 13.
  • a connecting adhesive application roller 15 is also arranged so that it can be lowered onto it and moved along it so that between the a small space remains between the two rollers 14 and 15.
  • connection adhesive application roller 15 can be, for example, an adhesive tape dispenser for double-sided adhesive tape or an application roller for liquid adhesive.
  • both rollers are mounted in a common, lowerable frame 16 in order to make the axial distance between the two rollers as small as possible.
  • the section of the surface 121 adjoining the holding adhesive groove 13 from the cutter bar 7 and the section of the surface 61 adjoining it are provided with an anti-adhesive layer 17.
  • the cutter bar 7 and the adhesive application plate 12 can be formed as a single element.
  • the elastic roller 11, the pressure roller 14 and the connecting adhesive application roller 15 can also be mounted in a common, movably or movably arranged holding element, so as to cut the web edge 42, perforate and apply the adhesive in a single operation and without being able to partially wind up the web 41.
  • FIG. 3 shows a greatly simplified perspective illustration of the knife bar 7 with the cutting knife 8 and the perforating knife 9 as well as the rubber roller 11 of the device 5 shown in FIG. 2.
  • the knife bar 7 and the rubber roller 11 can also be modified from the embodiment described with reference to FIG be arranged at an angle of less than 90 ° to the unwinding direction of the web 41. Instead of a straight cut edge, the start of the web is then given an oblique cut edge.
  • the pressing device 10 can have a bar made of elastic material, for example made of rubber, which presses the printing material over the entire web width onto the two knives and thus produces the cut and the perforation.
  • FIG. 4 shows, in a simplified perspective illustration (FIG. 4 a) and in a partial side view (FIG. 4 b), a printing material web roll 4 prepared in a first way according to the invention by means of a device of the first exemplary embodiment , the connection adhesive 19 required for gluing the old web to the new web and the perforation 43 which enables the new web to be torn off safely and free of damage after it has been glued.
  • the preparation of the adhesive tip of the new roll 4 with the device 5 shown in FIGS. 2 and 3 is carried out essentially in the manner described below.
  • the web 41 is unwound from the roll 4 and placed on the base plate 6 so that the web 41 completely covers the adhesive application plate 12 and the base plate 6.
  • the pressing device 10 located at one end of the cutter bar 7 is lowered onto the cutter bar 7 to such an extent that the rubber roller 11 presses on the cutters 8 and 9.
  • the web 41 is provided with a straight cutting edge 42 and a perforation 43 running parallel to the cutting edge 42 in a single operation by the pressure of the rubber roller 11.
  • the web 41 is wound onto the roll 4 by a predetermined web length. This length is dimensioned such that the cutting edge 42 comes to rest on the edge of the holding adhesive groove 13 facing the cutter bar 7. At the same time, the perforation 43 comes to lie on the surface 121 in the area corresponding to the space between the two rollers 14 and 15.
  • both adhesives are applied in a single operation: Pressure of the roll 14, a holding adhesive 18 located in the holding adhesive groove 13, is applied to the underside of a section 44 of the web 41 delimited by the cutting edge 42 and the perforation 43, and on the other hand, a connecting adhesive 19 is applied to the upper side of the section by the roll 15 44 applied from the area of the web 41 adjoining the perforation 43.
  • the holding adhesive and the connecting adhesive can be either of the same or of a different dosage form.
  • both adhesive tapes and spreadable or sprayable adhesives can be used.
  • the adhesiveness of the two adhesives can be different. However, both adhesives must have the property of bilateral adhesion.
  • the new printing material web roll in the roll changer is driven with a belt engaging on the circumference of the roll, it is expedient not to provide the area of the beginning of the web in which the belt touches the roll with the connecting adhesive 19. If the drive is made with several belts, several areas must be left out accordingly.
  • a modified design of the perforation in the cut-out area or in the cut-out areas is advantageous for belt drives. If you keep the continuous perforation shown in Figure 4 and leave it alone with an interrupted adhesive line, then when the perforation is torn, there is usually an uneven transfer of force to the tearable position of the printing material and thus uncontrollable tears in the area of the belt position or Belt positions. Triangular, round and, preferably, trapezoidal perforation courses have proven to be an advantageous design of the perforation in the belt area.
  • the web 41 is completely wound onto the printing material web roll 4.
  • the non-stick layer 17 prevents the adhesive applied to the underside of the web 41 from sticking to the surface 121 of the adhesive application plate 12 or to the surface 61 of the base plate 6.
  • winding the adhesive beginning of the web 41 of the web 41 means known per se, such as, for example (not shown) non-stick pressure rollers, ensure that the web 41 is wound without air entrapment and that the web start is secure and over the full width of the web on the roll 4 is glued.
  • the cutter bar 7 and the associated pressing device 10 on the one hand and the adhesive application plate 12 and the associated connecting adhesive application roller 15 on the other hand can each be designed to be pivotable.
  • one or the other pair of devices is pivoted into a position corresponding, for example, to the position of the knife bar.
  • the cutter bar 7 and the adhesive application plate 12 can be combined to form a single element, the perforating knife 9 and possibly also the cutting blade 8 being designed to be countersunk in the cutter bar 7 in order to ensure the dimensioning and guidance of the Not having to determine pressure roller 14 so precisely that contact of pressure roller 14 with one or the other of the two knives 8 and 9 is reliably prevented.
  • This modification of the exemplary embodiment also includes Combine pressing device 10 and the connecting adhesive application roller 15 to form a device which can be moved together over the printing material web.
  • the pressing device 10 and the connecting adhesive application roller 15 are axially aligned with one another, whether they are arranged axially parallel and one behind the other, whether they are arranged axially parallel but overlapping to one another or whether they are arranged in another suitable manner. Likewise, it is immaterial whether the pressing device 10 leads or lags the non-axial alignment during the movement from one web edge to the other web edge of the connecting adhesive application roller 15, whether - seen in slow motion - first cut and then adhesive is applied or vice versa. As a result, even in this development of the device according to the invention, the essential advantage of not having to first move the pressing device 10 and the connecting adhesive application roller 15 into an initial position is retained.
  • FIG. 5 shows the elements of a device for preparing a printing material web roll in a second embodiment according to the invention, insofar as this device differs from the device according to FIG. 2.
  • features which are shown and described and which correspond to the corresponding features of the device according to FIG. 2 are provided with the same reference symbols.
  • the cutter bar 7 has, instead of the perforating knife 9, a pair of perforating knives formed from two similar and offset-arranged knives, designated by the reference numerals 91 and 92.
  • the cutter bar 7 is composed of a first cutter holder 71 which is fixedly arranged in the base plate 6 (see FIG. 2) and a second cutter holder 72 which is adjustable relative to the cutter holder 71. While the first knife holder 71 has the first knife 91 in addition to the cutting knife 8, the second knife holder 72 has the second knife 92.
  • the first knife 91 is correspondingly arranged at a distance a from the cutting knife 8 and parallel to it.
  • the second knife 92 is arranged at a distance b (see FIG. 8) from the first knife 91 and parallel to it. Due to the adjustability of the second knife holder 72 relative to the first knife holder 71, the distance b between the two knives 91 and 92 can be set so that the desired perforation pattern of the perforation 43a, which is formed by the partial perforations 431 and 432, can be obtained.
  • FIG. 6 shows a simplified perspective illustration of a printing material web roll prepared by means of a device of the second exemplary embodiment in a second way according to the invention.
  • the adhesive 18 holding the start of the roll on the roll, the connecting adhesive 19 required for adhering the old web to the new web, and the perforation 43a which enables the new web to be torn off safely and without damage after the adhesive has been applied are clearly recognizable.
  • FIG. 7 shows different perforation patterns of the perforation 43a, which can be obtained with a device according to the second exemplary embodiment by a corresponding choice of the knife geometry.
  • the cuts made alternately by the first knife 91 and the second knife 92, viewed in the cutting direction , next to each other (A), with a distance (B) or overlapping (C).
  • FIG. 8 shows different perforation patterns of the perforation 43a, which can be obtained with a device according to the second exemplary embodiment.
  • the different perforation patterns in the embodiment according to FIG. 8 are obtained with knives of the same pitch but different distance b.
  • FIG. 9 shows, in a simplified side view of the preparation device, a change which can be carried out in the two exemplary embodiments described above, according to which the holding adhesive 18 is not applied by means of the holding adhesive groove 13 and the associated pressure roller 14. Instead, the holding adhesive 18 is applied by an application device 20 to the outermost layer of the printing material web roll to be prepared.
  • the size and arrangement of the surface section of the outermost layer to which the holding adhesive 18 is to be applied is to be determined in such a way that the section 44 of the beginning of the web delimited by the cutting edge 42 and the perforations 43 or 43a has this surface section after the web 41 has been wound up completely covered on roll 4.
  • the pressure roller 11 and the connecting adhesive application roller 15 can be attached to separate holding and guiding elements, which can be moved separately or together, on a common holding and guiding frame, as shown in FIG. 9, or in be arranged in any other appropriate manner.
  • the pressure roller 11 and the connecting adhesive application roller 15 are axially aligned with one another, whether they are arranged axially parallel and one behind the other, or whether they are axially parallel but overlapping.
  • a motor 21 is disclosed in FIG.
  • the motor 21 serves, in the manner described above, to partially and completely wind the web 41 onto the printing material web roll 4.
  • Figure 10 shows a further development of the device shown in Figure 9, the difference between the two devices essentially consists only in that the cutting knife 8 and the perforating knife 9 are mounted in a movable or movable holder 74 and that a pressure plate 75 on which the knives 8 and 9 are pressed, is arranged in the base plate 6.
  • the adhesive application can be carried out in accordance with FIG. 2 or FIG. 9.
