Definitions

  • the invention relates to a folding device with a first longitudinal folding device, a cross cutting device and a collecting cylinder, which is followed by a transport device comprising a belt conveyor system for forwarding the stacked copies to a second longitudinal folding device, and to a longitudinal perforating device which cooperates with parts of the transport device by a copy longitudinal perforation generated in the position of the second longitudinal fold fixed in relation to one another.
  • Such a folder is known from DE-AS 25 12 368.
  • the folded copies after the collecting cylinder are taken over by an additional transfer cylinder forming part of the transport device and transferred to a belt line which represents a further part of the transport device and which leads to the second longitudinal folding device.
  • a perforating roller carrying a perforating knife is attached to the transfer cylinder, in which a perforating groove ring is integrated.
  • the serrated perforating knife in cooperation with the perforating grooved ring, creates a perforated toothing on all of the folded copies lying one above the other at the height of the second longitudinal fold, as a result of which they are to be firmly connected.
  • the perforating device, the collecting cylinder and the transfer cylinder are stored in a first machine frame.
  • the second longitudinal folding device is arranged in a separate second machine frame. An attitude of the location of the second longitudinal fold on the center of the specimen requires an adjustment of the perforating knife and the perforating ring in addition to an adjustment of the second longitudinal folding device.
  • EP 0 257 390 A1 discloses a folding device of a non-generic type with a first longitudinal folding device, a cross-cutting device and a collecting cylinder, to which a transport device comprising a belt conveyor system for forwarding the stacked copies to a second downstream longitudinal folding device is arranged, and with a longitudinal perforating device which cooperating with parts of the transport device, the specimens are fixed in their position relative to one another by a longitudinal perforation created at the height of the second longitudinal fold.
  • the belt conveyor system has a perforating knife roller and a perforating grooved roller which is arranged to be adjustable together with the second longitudinal folding device.
  • the collecting cylinder is part of a cross folding device and interacts with two folding cylinders. His grippers mesh with the jaws of the folding cylinders.
  • Another folding device of a different type is known from EP 0 068 341 A4. It contains a folding jaw cylinder with means for lifting out folding products in order to transport them away via a belt guide.
  • the invention has for its object to develop a generic folder with a more compact structure so that an adjustment of all units involved in the second longitudinal fold is possible in one operation.
  • lifting fingers is in principle already known in connection with folding jaw cylinders, for example from DE-PS 31 24 639.
  • FIG. 1 denotes a former.
  • a paper web 2 which may already be multilayered due to previous longitudinal cutting and or overlapping of the cut web parts, is drawn over this by means of two pairs of pull rollers 3 and 4 and thereby receives its first longitudinal fold.
  • the paper web 2 is divided into individual sections 201 to 206 by a pair of cutting cylinders 5.
  • the sections 201 to 206 are accelerated to the speed of a subsequent collecting cylinder 10 in an acceleration device, which comprises two belt conveyor systems 6 and 7, their guide and deflection rollers, which are not described in more detail, and belt drive rollers 46, 47 and two tear-off rollers 8 and 9.
  • the belt conveyor systems 6 and 7 are aligned perpendicularly tangentially to the periphery of the collecting cylinder 10.
  • the belt conveyor system 6 accompanies the web section on the left-hand side until shortly before the tangent point with the collecting cylinder 10.
  • the collecting cylinder 10 is equipped in FIG. 1 with double grippers 11, three systems of which are evenly distributed around the circumference. Double gripper systems are known prior art (see, for example, the specialist book by A. Braun, Atlas des Drawing and Illustrations réellees, Frankfurt am Main, 1960, pp. 86/87) and are therefore not explained in more detail here.
  • the double grippers 11 each grasp a web section 201, 202, 203 at the front edge by means of their shorter gripper fingers and guide it up to a transfer point 12 around the collecting cylinder 10.
  • the collecting cylinder 10 can, depending on the number of desired copies lying one above the other, also make several revolutions in which the longer gripper fingers of the double grippers 11 each take over a further web section 204, 205, 206 and in this way a plurality of layers of web sections 201, 204; 202, 205; Feed 203, 206 together to transfer point 12.
  • the transfer point 12 are above the belt conveyor system 7, axially offset from the belts of the latter Locking tongues 13 arranged. These close the paper path at the transfer point 12 during the collection and release it in cycles when the collection is complete and the transfer is to take place.
  • the specimens between the transfer point 12 and the takeover point 15, at which the belts of the belt conveyor system 7 run tangentially to the collecting cylinder 10 are guided by guide tongues 16 surrounding the collecting cylinder 10 at a short distance.
  • the collecting cylinder 10 also has a lifting finger 14 in the vicinity of each of the double gripper systems 11.
  • the lifting fingers 14 are each axially offset behind the double grippers 11 in the direction of rotation of the collecting cylinder 10. They are in the applied state under the front edge of the folded copies and, as soon as they swing out at the transfer point 12 from the periphery of the collecting cylinder 10 when the double grippers 11 open and the locking tongues 13 open, run ramps for the folded copies.
  • the opening and closing of the double grippers 11 and the movement of the lifting fingers 14 are controlled in a known manner by roller levers running on control cams. Since these actuating mechanisms have long been known to those skilled in the art of folder construction, they are neither shown nor described in detail here.
  • the belt conveyor system 7 is guided closely around the part of the collecting cylinder 10 between the takeover point 15 and the transfer point 12 and thereby holds the specimens held by the double grippers 11 in contact with the collecting cylinder.
  • the web sections lying one above the other are pressed down at the transfer point 12 by the lifting fingers 14 out of the opening double grippers 11 and placed on the belt conveyor system 7 with the closing tongue 13 pivoted away.
  • a further belt conveyor system 17 is brought up to the transfer point 12 from above, which, together with the belt conveyor system 7 running below, conveys the specimens from the transfer point 12 in a narrow manner from both sides.
  • the belt conveyor systems 7 and 17 are subsequently passed between two pairs of belt guide and drive rollers 18, 19 and 20, 21.
  • roller pair 22, 23 arranged, the upper roller 22 is designed as a perforating knife roller and the lower roller 23 is provided with a perforating groove ring into which the perforating teeth of the perforating knife are immersed.
  • the lower roller 23 also serves to guide the belt. This can be seen better in detail from FIG. 2.
  • the belts of the one designated by 7 are guided down around the roller 21 and then back over several deflection and tensioning rollers to the start of the acceleration path in the vicinity of the drive cylinder 47.
  • the belts of the system 17 are guided upwards around the roller 20 and then back to the transfer point 12 via a plurality of deflection and tensioning rollers.
  • Further belt conveyor systems are available for transporting the folded copies through the perforation rollers 22, 23 and for further transport to a longitudinal folding device.
  • the folded copies are thus supported on their underside by three belt conveyor systems 24, 25, 26, of which the first 24 are guided around the roller 19 on the right-hand side, the second 25 around the roller 23 on the right-hand side and the third 26 around the roller 21 on the right-hand side.
  • the belt conveyor systems 24, 25, 26 run parallel on their remaining route up to the deflection and tensioning rollers behind the second longitudinal folding device.
  • the belts of a belt conveyor system 27 are guided around the roller 18 on the right-hand side from above and the belts of a further system 28 are guided around the roller 20 on the right-hand side from above.
  • Both belt conveyor systems 27, 28 run parallel to the deflection and tensioning rollers behind the second longitudinal folding device.
  • the folded copies conveyed by the belt conveyor systems 7, 19 and 23 on the underside and 17 and 27 on the top by the rollers 22, 23 equipped with perforating knife and grooved ring and perforated in the stretched position are made by the belt conveyor systems 24, 25, 26 and 27 respectively , 28 of the second longitudinal folding device. Due to the perforation at the level of the second longitudinal fold that follows, the superimposed copies are fixed in their position relative to one another.
  • the second Longitudinal folding device consists of a folding knife cylinder 29 and a pair of folding rollers 30.
  • the specimens pressed by the extending folding knife of the folding knife cylinder 29 between the folding rollers 30 and provided with a second longitudinal fold by the latter are finally picked up by a paddle wheel 31 and deposited by the latter on a delivery belt 32.
  • the pairs of pull rollers 3, 4, the pair of cutting cylinders 5 and the collecting cylinder 10 are mounted in machine side walls 33 of the machine main frame.
  • the second longitudinal folder, i.e. the folding knife cylinder 29 and the pair of folding rollers 30 are mounted together with the tape guide and drive rollers 18, 19, 20, 21, the perforating knife roller 22 and the perforating grooved roller 23 interacting with the latter in an auxiliary frame 34.
  • the auxiliary frame 34 is mounted within the main machine frame so that it can be moved perpendicular to the second longitudinal fold.
  • the subframe 34 is moved in suitable horizontal guides 37, 38, 39 and laterally arranged vertical guides 40, 41 via a spindle 43 which is actuated by means of a handwheel 42 and is mounted in a bearing block 44.
  • This bearing block is connected to a side wall 33 of the machine main frame via a cross member 45.
  • the subframe 34 can, however, also be moved by means of an electric motor which is strongly reduced by means of a multi-stage gear.
  • other known means are also available to the person skilled in the art, e.g. a hydraulic or pneumatic motor or piston.
  • the decisive advantage of the arrangement of the longitudinal perforating device and the second longitudinal folding device in the auxiliary frame 34 is that both devices can move synchronously during operation and can thus be adjusted to the center of the folding copy coming from the former.
  • the perforating knife roller 22, the roller 23 cooperating with it and the others Tape guide and drive rollers 18, 19, 20, 21 are arranged so that their spacing from one another is adjustable for adjustment to the respective thickness of the fold.
  • the perforating knife roller 22 and the upper tape guide and drive rollers 18, 20 are preferably mounted in adjustable eccentrics 48 shown in FIG. 2 using the example of the perforating knife roller 22.
  • the double grippers 11 shown in FIG. 1 on the collecting cylinder 10 can - as shown in FIG. 3 - also be replaced by pin needles 35 '.
  • all other parts analogous to Fig. 1 are provided with the same reference number and an additional index " ⁇ ".
  • the number of gripper or pinpoint needle systems on the collecting cylinder 10, 10 ' can be variably determined in coordination with the format lengths. For example, five puncture needle systems 35 'are shown in FIG. 3, as a result of which the reference numbers for the illustrated track sections increase to 201' to 208 '.
  • the lifting fingers 14' are designed such that they surround a puncture needle 35 'in the manner of a fork. 1, when using puncture needles 35 'instead of the guide tongues 16, a further belt conveyor system 36' is used to guide the specimens in the upper half of the collecting cylinder when collecting.
