Definitions

  • the invention relates to a winding machine according to the preamble of claim 1.
  • Such a 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 lateral 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 lateral surface of the roller remains.
  • a similar device has become known from DE-AS 29 30 474.
  • 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.
  • 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 invention is based on the object of designing a winding machine in accordance with the preamble of claim 1 in such a way that, in the case of stiff, heavy types of paper, the separating device bends or its parts is prevented, and that no impermissibly high forces act on the joint between the blade support and the plate; in any case, it should be ensured that the web is properly separated.
  • the separating device shows a finished wound roll 5 resting on two support rolls 3 and 4 of a support roll winding machine.
  • the incoming web 6, which partially wraps around the support roll 3, has not yet been separated from the finished roll 5.
  • a separating device has already been brought up between the two support rollers 3 and 4 in the gusset formed between the support rollers 3 and 4 and the winding 5.
  • the separating device consists of a bar 7 guided on both sides, which has a pivotably arranged blade carrier 8 at its upper end, to which a tear-off blade 9 is screwed.
  • In the blade support 8 are spaced from the tear-off blade 9 screwed holding members 10 screwed distributed over the blade width.
  • the holding members 10 carry on their ends facing the support roller 3 felt pads 11.
  • the blade support 8 can by means of lateral Linkage 12, which engage on levers 13 fixedly attached to the carrier, are pivoted against the support rollers 3 (FIGS. 2 and 3). In this operating position, the holding members 10 clamp the web 6 firmly against the support roller 3, while a small gap s remains between the tear-off edge of the blade 9 and the web 6. Only when the winding 5 is moved by the squeezing roller 14 over the second support roller 4, the web 6 comes to rest against the tear-off edge of the tear-off blade 9, which can be toothed in a manner known per se as a perforated edge. The web 6 tears off the finished roll 5 and the latter can be conveyed on.
  • a vacuum is applied within the support roller 3, which holds the separated fabric web through holes 15 in the support roller jacket, so that the tear-off blade 9 can be pivoted away from the fabric web and the entire separating device can be lowered again in order to provide space for a new winding core to be inserted into the gusset create, which then holds the incoming web against the support roller 3.
  • the web 6 is glued to the winding core in a manner known per se, for example by an adhesive strip applied to it.
  • the blade carrier 8 is designed as a double lever. It comprises two lever arms 8a and 8b, as can be seen from Fig. 3. It is articulated on beam 7 (also called “plate” above) - see joint 20. Lever arm 8b has a support surface 21. This is slightly beveled with respect to the longitudinal axis of blade carrier 8, in such a way that in the operating state according to FIG 3 - thus at the moment of cutting - more or less fully abuts against the lateral surface 22 of the supporting roller 4. When the winding 5 is ejected from the winding bed, as shown in FIG. 2, a tension occurs in the web 6 between the blade 9 and the pressing roller 14.
