Definitions

  • the invention relates to a clamping cone for receiving a wound roll of material carrying sleeve in a roll changer according to the features of claim 1.
  • clamping cones are motor introduced into the sleeves of the material rolls and usually automatically clamped by means of jaws to ensure optimum torque transmission to the sleeve.
  • different winding tubes are used in the prior art, which have different inner diameters.
  • 3-inch and 6-inch cores which are mentioned here by way of example as different types, are widespread.
  • a mandrel which is provided for sleeves with different diameters.
  • This mandrel has in the axial direction one behind the other lying several different sized recordings, which can be brought to bear on the inner circumference of the roll of material and whose diameter is variable in a certain range.
  • the change in the diameter of the recordings is made by clamping jaws, which are adjustable in the radial direction to the outside.
  • clamping jaws designed as a piston actuator is provided with conical piston sections. With axial displacement of the actuator, a radial adjusting movement of the clamping jaws takes place.
  • a disadvantage of this solution is that due to the axial extent of the clamping jaws through the successively arranged recordings, a different control of the roller support arms and a larger (wider) construction of the roll changer is required. In order to be able to take up the largest roll width, the support arms must first be moved apart until the roll of material fits in between. This requires a greater travel than the clamping cones with only one shot.
  • the DE 34 39 628 A1 discloses a reel, with a spreadable segments having drum, on which an expandable sleeve is attachable to adapt to different coil inner diameter.
  • the US 2001/0054667 A1 shows a holding mechanism for paper roll tubes with different inner diameter.
  • the FR 768 300 A shows a clamping shaft for large variants of the diameter.
  • the invention has for its object to provide a clamping cone for receiving a wound roll of material bearing sleeve in a reel changer.
  • the advantages achieved by the invention are, in particular, that the adjustment of the clamping cone for different types of tube material rolls can be done very easily and without major changeover times on the roll changer. Furthermore, the clamping cone has no substantially greater axial extent than the clamping cones previously used, which facilitates threading the uprights. In addition, this can be maintained the previous design and control of the roll changer.
  • a clamping cone comprises an inner cone and an outer cone which can be attached to it.
  • the inner cone is designed to accommodate a roll of material of a small first type (3-inch winding tube, sleeve inner diameter 3 inches or 75 mm). It comprises a plurality of circumferentially distributed inner clamping jaws, which are preferably radially adjustable. In a preferred embodiment, four internal clamping jaws are provided.
  • the outer cone is designed as an adapter and pushed onto the inner cone, so that now a roll of material of a large second type (6-inch winding tube, sleeve inner diameter 6 inches or 150 mm) can be raised.
  • the outer cone preferably also comprises a plurality of outer clamping jaws distributed on its circumference, which are radially adjustable for better sleeve tension. In a preferred embodiment, four outer clamping jaws are provided in the outer cone.
  • the clamping cone is preferably arranged in a reel changer of a rotary printing press.
  • Fig. 1 shows an inner cone 01, which is attached to a roller support arm 02 of a not shown in this view reel changer.

  • the toggle mechanism 04 operates in the manner by a control axis 06 is displaced in the axial direction.
  • Adjusting elements 07 which are movably mounted on the adjusting axis 06, engage in bulges 08 of the inner clamping jaws 03 and stretch by sliding along the bulges 08 of the inner clamping jaws 03 like a screen, whereby the inner clamping jaws 03 are moved in the radial direction to the outside.
  • clamping mechanism can also be embodied in other ways, for example by an axial movement of an actuating piston with conical piston sections, which interact with correspondingly shaped sections of the clamping jaws.
  • a leaf spring package 05 is z. B. from at least one leaf spring 09 and an additional leaf spring ( Fig. 5 ).
  • a centering cap 12 is provided, which facilitates threading of a material sleeve of a roll of material during Aufachsvorgang by their conical shape.
  • An ejector 13, z. B. Auswerferility 13 with a detachable inner part 14 is provided on Rollentragarm 02 to realize an ejector for empty material sleeves, which will be explained later in more detail.
  • Fig. 2 shows a spatial representation of the inner clamping jaw 03.
  • the bulges 08 are already described radial adjustment of the inner clamping jaws 03 by means of the toggle mechanism 04.
  • At the cone base body 11 facing end surfaces of the inner clamping jaw 03 each have a groove 16 is provided, in which the inner leaf springs 09 mounted in the State intervenes.

  • the inner leaf spring 09 is preferably made of a flat metal band, which is biased arcuately. It can also summarized several leaves (spring layers) with different lengths and biases to a leaf spring package which is held together by a common heart bolt and spring clips. By inserted plastic flakes or lubrication with grease, the friction is reduced when the ends of the layers move by length change during compression against each other.
