Definitions

  • the invention relates to a winding machine according to the preamble of claim 1. Reference is made to DE 41 28 095 A1.
  • a similar winding machine has become known from DE 31 09 587 C2.
  • the aim is to take measures to prevent the blade from damaging the drive surface of the roll wrapped in the web when the web is cut.
  • the blade carrier is assigned a holding member which can be supported on the paper web and thus on the outer surface of the roll wrapped in the web at the moment of cutting, so that a certain minimum distance between the cutting edge of the blade and the outer surface of the roller remains.
  • the holding member cooperates with a narrow edge provided with recesses with a perforating blade provided with corresponding recesses, which is moved towards the holding member essentially in the circumferential direction of the support roller at a distance from its surface.
  • a separate bracket and a separate swivel drive are required for both the holding member and the perforating blade.
  • DE-OS 26 38 368 relates to a winding machine in which a separating device is brought up from above via one of the two support rollers to the paper web to be cut, and which therefore belongs to a different genus.
  • a pneumatic unit is used for the introduction.
  • the winding machine according to the mentioned DE 41 28 095 A1 solves a particular problem that appears particularly unpleasantly with heavy, stiff types of paper. If the finished winding roll is ejected from the winding bed, so that the web to be cut rests under tension on the cutting edge of the blade, this exerts a force on the blade, and thus on the blade carrier and on the entire web cutting device.
  • the web separator generally consists of a machine-wide plate that is supported at both ends. This plate and possibly the blade carrier are bent due to the aforementioned force. If the blade is no longer particularly sharp, this can result in the bend not cutting through the web at all.
  • the problem is solved in that the blade carrier is designed as a double lever, one end of which supports the blade and the other end (support end) of which supports the blade carrier on the lateral surface of the carrier roller free of the web during the cutting process of the blade, so that a self-locking storage of the blade carrier takes place.
  • the winding bed which is formed between the two support rollers is limited in its upper region by the outer surface of the roll. If the roll has a large diameter, it does not extend so far into the Space between the two support rollers; however, if it has a small diameter, it extends further down into the space between the two support rollers. The height of the space between the two support rollers in the area of the winding bed is therefore different, depending on whether it is a roll with a large or a small diameter.
  • the separating device When the separating device is brought into position, it has to be moved a certain distance upwards, namely so far that the blade carrier can be tilted into the inclined position, one end of the blade-carrying end facing the web of material, while the other, so-called support end, is supported against the outer surface of the non-web-wrapped roller.
  • the entire separating device - together with the blade carrier - can be lowered somewhat again. This means that the cutting device must be moved to a slightly higher position than is necessary for the cutting work before cutting the web. With regard to the limitation of the space between the two support rollers, this can become critical for rollers with a small diameter; the height of the room is then no longer sufficient.
  • the invention has for its object to design a winding machine according to the preamble of claim 1 such that the winding bed height can be better used by the separating device does not have to be raised so far, so that even with smaller rolls, proper operation is guaranteed.
  • FIG. 1 two carrier rollers 3 and 4 of a carrier roller winding machine can be seen.
  • a finished paper roll 5 rests on the support rollers.
  • the incoming web 6, which partially wraps around the support roller 3, has not yet been separated from the finished roll 5.
  • a separating device has already been brought up between the two supporting rollers 3 and 4 in the gusset formed between the supporting rollers 3 and 4 and the winding 5.
  • the separating device consists of a bar 7 guided on both sides, which has at its upper end a pivotably arranged blade carrier 8, to which a tear-off blade 9 is screwed.
  • the rotatably mounted jacket is provided with a large number of bores 15. A vacuum can be applied inside. Carrier roller 4, however, asked for a closed outer surface.
  • FIG. 2 shows further details of the entire machine, in particular the contour of the paper web 6 when the paper roll 5 is ejected. Individual positions of the paper roll are shown in dashed lines and identified by I, II and III.
  • Fig. 3 again shows the rollers 3 and 4, and in the cutout.
  • the blade carrier 8 has the blade 9 at one end, while its other end has a support surface 21.
  • the blade carrier 8 is connected to the supporting structure 7 by means of a connecting member 40.
  • joints 41 and 42 are provided. It can now be clearly seen that the blade carrier 8 can be moved into a tilted position, even without the entire separating device - including the supporting structure 7, the connecting member 40 and the blade carrier 8 - being able to be raised to a higher level.
  • the blade support 8 can namely pivot due to the action of the link 40 already when starting up in the tilted position.
  • the joint 42 does not necessarily have to rest on the blade-side end of the blade carrier 8. Rather, this joint could also be moved a little further towards the center of the connecting link.
  • the support structure 7 does not have to consist of a single beam, but z. B. can be a latticework.
  • the connecting member 40 - shown in the form of a rod in this side view - is in fact conceivable as a plate or as a plurality of parallel rods. The same applies to the blade carrier 8.
  • FIG. 4 illustrates three positions that the blade carrier 8 and the connecting member 40 can assume.
  • position 1 the entire unit, consisting of support structure 7, blade carrier 8 and connecting member 40, is moved into the basic position.
  • Position 2 is an intermediate position.
  • Position 3 is then the working position in which the paper web is finally cut.
  • the adjustment mechanism comprises a pneumatic unit, with cylinder 50, piston rod 51 and pivot lever 52.
  • the pivot lever 52 engages blade carrier 8 or is located in its extension.
  • Fig. 5 illustrates the various forces that occur during the cutting process.
  • the invention can also be used advantageously if the distance between the cutting edge of the blade 9 and the outer surface of the roller 3 is greater. Distances of several centimeters are conceivable.
  • the angle between the connecting member 40 and the longitudinal center plane through the roller 5 need only be minimal. It is even conceivable that the connecting member 40 is absolutely vertical at the moment of cutting.
