Definitions

  • the invention relates to a clamping head for a web wound on a sleeve with a support arm and a mandrel arranged therein and insertable into the sleeve.
  • Clamping heads of this type are used, for example, to fix a paper web roll in roll changers of web-fed rotary printing machines.
  • the invention has for its object to provide a generic chuck that has a simple structure, Space-saving ejector for the sleeve of a developed web, which does not require its own drive.
  • a clamping head according to the invention is characterized in that, despite the arrangement of an ejector, it enables a very rigid mounting for the mandrel, since the support arm and thus the front bearing for the mandrel can be advanced far towards the tip of the mandrel, but without the Travel to adjust the side edge of the web to be unwound from the roll is restricted inadmissible.
  • FIG. 1 An embodiment of the invention is shown.
  • the drawing shows a longitudinal section through the essential parts of a clamping head according to the invention.
  • the clamping head comprises a support arm 1.
  • the support arm 1 can be firmly connected to a fixed side wall or to the arms of a roller star.
  • a gearwheel 2 is rotatably mounted in the support arm 1, the teeth of which are connected to a rack 3 of a bearing bush 4 comb.
  • the bearing bush 4 is guided axially displaceably in the support arm 1.
  • the gear 3 can be operated in a manner not shown either by hand or by means of a servomotor.
  • a mandrel 6 is rotatable by means of a front roller bearing 5 and a further roller bearing, not shown, but is axially immovable relative to the bearing bush 4.
  • the free end of the mandrel 6 protruding from the bearing bush 4 is provided with spreading jaws 7 known per se, not shown in more detail, for fixing a slid-on sleeve of a web roll.
  • An end face 8 of a clamping ring 9 forms a stop for the sleeve to be pushed on.
  • the support arm 1 has an end face 10 with a plurality of cylindrical recesses 11. Three cylindrical recesses 11 are expediently provided.
  • a guide pin 12 with a cylindrical head 13 of larger diameter protrudes through each of the cylindrical recesses 11.
  • the guide bush 14 has at its end facing the support arm 1 an annular, inwardly extending extension 16. With the inner surface of the extension 16, the guide bush 14 is slidably mounted on the guide pin 12.
  • the annular extension 16 also forms an abutment for one end of a helical compression spring 17 which surrounds the guide pin 12. The other end of the compression spring 17 is supported on the head 13 of the guide pin 12.
  • the inner diameter of the ejector ring 18 is only slightly larger than its outer diameter facing the end face 8 of the clamping ring 9. It is smaller than the outer diameter 19, indicated by dashed lines, of a sleeve to be ejected.
  • the end face 20 of the ejector ring 18 is also shown in the position in which the mandrel 6 is extended as far in the direction of the arrow "a" as is necessary for clamping a sleeve of a web roll.
  • the compression spring 17 ensures that the ejector ring 18 rests on the end face 21 of the bearing bush 4 in a force-fitting manner and thus a constant distance "c" is always maintained so that the static ejector ring 18 can never start on the rotating sleeve of a web roll.
  • This configuration makes it possible to move the mandrel 6 to adjust the side edge of the web to be unwound by a certain path in the direction of the arrow "a" or "b” without the ejector ring 18 exerting an axially acting force on the clamped sleeve.
  • the mandrel 6 is moved by means of the toothed wheel 2 over the toothed bearing bush 4 in the direction of arrow "b".
  • the ejector ring 18 stops and begins to exert a force acting in the stripping direction on the sleeve.
  • the mandrel 6 now continues until the edge 23 of the mandrel disappears under the end face 20 of the ejector ring 18 and thus a reliable stripping of the sleeve is ensured.
