Definitions

  • the invention relates to a web feed device for paper roll change in rotary printing machines according to the preamble of claim 1.
  • This device has a large overall height, since the frame holding the rollers is rotatably mounted in the center. This means that the required minimum overall height for the previously known reel changing devices is predefined for given reel diameters. In general, however, compact units are often required in order to keep the converted space for the machine system as small as possible. This roll changing device cannot be used in the case of existing old structures with low room heights. In addition, enclosed space is expensive.
  • a low-type roller changing device in which the rollers to be changed are moved by means of swivel arms about horizontally arranged swivel shafts.
  • the paper web to be changed ie new paper web
  • This adhesive press is described in US Pat. No. 4,170,506 and can only connect the paper webs when the rolls are at a standstill.
  • the amount of paper required for ongoing production is meanwhile removed from a paper web storage which is formed by tensioning rollers and is located above the gluing press.
  • This device for paper web connection which carries out the gluing process only when the paper rolls are at a standstill and which has a paper web storage device, is disadvantageous in that the paper web storage device has only a limited storage capacity. This principle cannot be used in high-performance rotary printing presses due to the resulting loss of productivity.
  • the invention has for its object to provide a web feed device for paper roll change in rotary printing presses with low height and flying roll change in a simple design for high-performance rotary printing presses.
  • the advantages of the present invention consist in particular in the fact that a paper feed device for flying reel changes has been created, which has been designed without a pit, with a considerably low overall height.
  • the use of a paper memory during the roll change is not necessary even during production.
  • Fig. 1 shows the front view of the web feeding device, wherein one of the two side walls 1; 2 of the machine frame has been omitted.
  • the side walls 1; 2 take support arms 3; 4, which is pivotable and with bearings 6; 7 can be provided.
  • At the end of the support arms 3; 4 are each on a mandrel 8; 9 stored paper rolls 11; 12, which are designed with motors, not shown, for the roller drive and for the roller braking.
  • the support arms 3; 4 have their working position in the horizontal.
  • the side walls 1; 2 each have a first guide plate 13, which guide strips 14; 16 has on which adhesive trolley 17; 18 are movable in the direction of arrow X.
  • Fig. 1 shows the adhesive carriage 17 in the rest position and the adhesive carriage 18 in the working position.
  • the adhesive carriage 18 has left the position 18 'shown in dashed lines in the direction of the arrow X and takes the position shown in solid lines on the paper roll 11 in the adhesive position.
  • the adhesive carriage 17; 18 are on the guide rails 14; 16 each in the direction of the mandrels 8; 9 of the paper rolls 11; 12 movable.
  • the side walls 1; 2 have a second guide plate 19 and a guide roller 21, a dancer roller 22 and a pair of pull rollers 23. Another guide roller 24 and deflection rollers are arranged in the first cross member 13.
  • the adhesive carriage 18 is in the working position, ie the gluing roller 54 presses the paper web 67 of the paper roll 12 which is coming to an end against the new paper roll 11.
  • the adhesive carriage 18 consists of two plates 28; 29, only the plate 28 being shown in FIG. 2.
  • the two plates 28; 29 are, according to FIGS. 2 to 5, seen at right angles to the plate surfaces and in the direction of movement X, at the corner points of the plates 28; 29 located paper guide spindles 31; 32 connected.
  • the travel spindle 39 and the shafts 34; 36 have a cam roller 41 at each end, which is guided in an upper guide bar 16.1 and a lower guide bar 16.2 of the guide bar designated as a whole 16 and serves to ensure the stability of the adhesive carriages 17; 18.
  • the drive gears 37; 38 of the adhesive carriage 18 are above the shafts 34; 36 each with a rack 44 in operative connection.
  • the rack 44 is firmly connected to the upper guide bar 16.1.
  • the drive gears 37; 38 mesh with another gear 46, which is rotatably connected to the shaft 47 of an electric drive motor 48.
  • the motor 48 has an electrical connection 49.
  • 31 pivot levers 52 are attached to the bearing pin of the paper guide roller, which receives the axis 53 of the adhesive roller 54.
  • the pivot lever 52 has an articulation point 56 for the piston of a working cylinder 57.
  • the articulation point 56 is designed by a fork head 58 with bolts.
  • Another articulation point 59 for the working cylinder 57 is located on the plate 28.
  • a knock-off knife 61 for the paper web 67 can be actuated by further working cylinders 63 via pivoting lever 62.
  • the working cylinder 63 is also designed as a fork head and is connected to the pivot lever 62 at the pivot point 64 and to the plate 28 at the pivot point 66.
  • the working cylinder 57; 63 are preferably designed as pneumatic working cylinders.
  • the way it works is as follows.
  • the paper web 67 leaves the paper roll 12 according to FIG. 1 and runs over the guide rollers 24; 21, via the dancer roller 22 and the pair of pull rollers 23 for further processing in the subsequent units.
  • the paper roll 11 is rotated and accelerated by known means until the peripheral speed of the paper rolls 11; 12 is the same.
  • the adhesive carriage 18 moves from the position 18 'in the direction of the mandrels 8 of the paper roll 11 and takes the paper web 67 running off the paper roll 12 with it, so that it now via the paper guide spindles 32; 31 and the adhesive roller 54 arranged between them runs and only then comes to rest against the guide roller 24 described above.
  • the paper roll 11 has on its outer paper web a known adhesive preparation 68, for example with glue, onto which the adhesive roller 54 receives the pulse for connecting the paper webs after scanning a reflective film 69 by means of a photocell (not shown). After the connection has been made, the remaining web is separated from the paper roll 12 by the knock-off knife 61. The adhesive carriage 18 moves back to the starting position 18 '. The paper web 67 now continues from the paper roll 11 via the guide roller 24, as already described. Instead of the expired paper roll 12, a new, not shown, full paper roll 12 'can be received, which can be connected to the paper roll 12' after the paper roll 11 has run out by actuating the adhesive carriage 17 in the direction of the mandrels 9 of the paper roll 12 '.
  • a known adhesive preparation 68 for example with glue
  • the control of the paper roll change can be done by hand or by the computer of the printing device.
  • a flying paper roll change is thus carried out in a simple manner at full production speed with a significantly lower overall height and without the use of a paper store.
