Definitions

  • the invention relates to a roller consisting of a rotatably mounted Carrier mandrel and a mountable on this carrier mandrel and again removable, preferably with at least one coating provided, sleeve.
  • WO 01 / 30547A1 describes that rolling with push-on sleeves are known from flexographic printing.
  • the pod will pushed onto a carrier body by an air cushion between Sleeve and carrier body is generated.
  • the carrier body can be used as So-called air cylinders are designed with air outlet openings its surface.
  • Sleeves are known from flexographic printing, their flexible surfaces do not have the print motif, but as a cushioning intermediate layer serve to comparatively hard printing plates, which the actual Wear print motifs to record.
  • WO 01/30574 are also two-part sleeves, with a Sleeve core which is mounted directly on the carrier cylinder and with a of which separate outer sleeve, which has the surface, described.
  • a core of the sleeve is supported by compressed air driven cylinder and can be removed from it become.
  • the sleeve core consists of a shrinkable material.
  • a material like that from commercially known so-called heat shrink tubing is known, used.
  • the core of the pod is deliberately undersized compared to the cylinder on which the sleeve will be used later should be the necessary clamping forces after exiting the compressed air supply.
  • the invention is therefore based on the object of security against Increase relative movement of the sleeve to the carrier mandrel.
  • At least one Fixing device for non-rotatable and releasable attachment of the Sleeve is provided on the carrier mandrel.
  • the Fixing device is the sleeve in axial as well Fixed and held in the circumferential direction in its position. Even pods with soft and thick-walled coatings are even at high Speeds fixed in their position on the carrier mandrel. This increases the Occupational safety and guarantees an error-free machining process.
  • the inner diameter of the sleeve if this is removed from the carrier mandrel, is smaller than that Outside diameter of the carrier mandrel. This measure will achieves that the position is maintained by the clamping forces that occur the sleeve in addition to the use of the fixation device is improved. It is also conceivable that the inside diameter of the Sleeve, if this is removed from the carrier mandrel is not smaller than that Outside diameter of the carrier mandrel is. In this case, the position the sleeve on the carrier mandrel alone by the fixation device held. This measure allows much cheaper sleeves to be produced.
  • the fixation device has shaped elements that in engaging correspondingly adapted counter elements of the sleeve are arranged.
  • a Form fit between the fixing device and the sleeve. at the shaped elements can be, for example, rectangular pins act on the key-lock principle in rectangular Recesses are arranged engagingly in the sleeve:
  • the fixing device as Retaining ring with an axially engaging in the face of the sleeve Gearing is formed.
  • the toothing takes over the function here a key, which in corresponding recesses (lock) of the Front side of the sleeve is designed to engage.
  • the retaining ring can be attached using a Torque support is rotatably connected to the carrier mandrel.
  • a Torque support is rotatably connected to the carrier mandrel.
  • Form elements interlocking with the counter elements in a wedge shape are trained.
  • the tips of the parts are advantageously blunted.
  • the wedge-shaped form elements mesh with one another without play also have a leadership role in the introduction of the form elements into the counter elements.
  • flanks of the teeth of form elements and Counter elements lie against one another essentially without play.
  • At least one screw preferably a fitting screw is provided, which the front of the Retaining rings penetrates and by means of a thread with the end face of the Carrier mandrel is screwable.
  • the described configuration of the Torque support as a screw is structurally advantageous and therefore inexpensive.
  • At least one union nut is provided as a torque arm which can be screwed onto an external thread on the carrier mandrel, whereby a pressure of the union nut on the sleeve and thus the Sleeve is made on the end face of the support dome.
  • the Torque is transmitted from the carrier mandrel to the sleeve the fixation device laterally pressed onto the support dome, and / or by an additional torque arm, for example by Dowel pins that determine the angular position of the sleeve relative to the support dome.
  • the carrier mandrel and thus also the sleeve is cylindrical.
  • the Carrier mandrel is conical, for example conical Retrofit carrier mandrels with a fixation device.
  • the two fixation devices are, one on each end of the Sleeve arranged.
  • the invention also relates to a method for fixing a sleeve a carrier mandrel.
  • the sleeve is advantageously pressed onto the carrier mandrel by means of compressed air reared.
  • compressed air is often flexible Expand the sleeve before it can be pulled over the carrier mandrel. After removing the compressed air, the clamping action of the sleeve occurs Carrier mandrel.
  • the electrical leakage resistance, especially between Work surface and support mandrel is variable, preferably by choice a material of the fixing device is variable.
  • a material of the fixing device is variable.
  • the appropriate length of the Creepage distance, as well as from the manufacture of the fixation device a correctly chosen material combination of electrically insulating and electrically conductive materials and the positioning of high-resistance elastomer materials in the field of coating the Sleeve that there is no rollover between the ESA coating and the components of the Fixation device comes.
  • the required Insulation restricted to a defined resistance range represent without the electrically conductive layers of expensive CFRP materials, as usual today, must be used.
  • roller loads from Conveyed goods are picked up and / or delivered to this.
  • the number of loads can be selected, for example, by selecting the Control the material of the fixation device.
  • Figure 1 is a roller 1, consisting of a support mandrel 3 and sleeve 2 shown thereon.
  • the sleeve 2 has one Coating 13, the working surface 4 for transport, for Printing, etc. of material webs, not shown, is used.
  • the sleeve 2 and the carrier mandrel 3 cylindrical.
  • the sleeve 2 is by means of a fixation device 5 rotatably connected to the carrier mandrel 3.
  • the fixing device 5 consists essentially of a retaining ring 6, which extends over its circumference has uniformly distributed axial shaped elements 7.
  • the shaped elements 7 engage in the end face of the sleeve 2, the corresponding as Counter elements 8 designed recesses.
  • form and counter elements becomes one Form fit between fixation device 5 and sleeve 2.
  • the retaining ring is non-rotatably connected to the by means of torque supports 9 Carrier mandrel 3 connected.
  • torque supports 9 are in this Embodiment screws used, the front of the Penetrate retaining rings 6 and with at least one thread 10 in the Front side of the support mandrel 3 can be screwed.
  • the shaped elements 7 on the retaining ring 6 are rectangular designed. These shaped elements 7 also engage in corresponding ones Counter elements 8 in the sleeve 2, whereby a positive connection between Fixing device 5 and sleeve 2 is made.
  • FIG 4 is the fixation device 5, consisting of retaining ring 6 and Shaped elements 7 shown in Figure 3.
  • the front Threads 10 can be screwed into the carrier mandrel 3.
