Definitions

  • the invention relates to a clamping head for a slitter-winder and winding machine and a slitter-winder and winding machine with winding levers, to each of which a clamping head is rotatably mounted.
  • Wound cutting and winding machines are known for winding webs, in particular of plastic films and metal foils, to wound rolls.
  • the webs are wound on sleeves, which are held at both ends by a retracted into the sleeve clamping head.
  • each chuck is rotatably mounted on a winding lever.
  • a tensioning device for winding core which contains a plurality of radially adjustable in a cage tubular segment-shaped clamping segments, which are arranged around a pin with equilateral polygonal cross-section. Between the pin and the clamping segments rotatable support elements are arranged, of which the clamping segments are moved in a force exerted on the pin torque in the radially outward direction into a clamping position.
  • Slitter and wrappers must be equipped to handle sleeves of different sizes.
  • the machines In a change of format, the machines must be converted as quickly as possible to chucks with a different diameter.
  • the invention is based on the object to provide a clamping head, which is quickly replaced, even at high working speeds of the slitter and winder guarantees an exact concentricity of the sleeve and is able to automatically tension even sleeves with slightly varying inner diameter and to center.
  • the design of the clamping head with a central support hub which has a polygonal-hub profile shaped bore, makes it easy to postpone the clamping head on a correspondingly shaped profile and attached to the winding lever shaft journals and secure there.
  • polygon profiles derived from an equilateral triangle are used for both the hub and the journal.
  • the polygon connection has the advantage that when a torque is introduced, the play between the hub and the shaft journal is eliminated by a slight rotation and thus the clamping head is ideally centered on the shaft journal.
  • the attachment of the clamping head to the shaft journal by means of a central clamping screw which extends through the polygonal bore in the hub and carried in a threaded introduced in the center of the shaft journal threaded bore.
  • a central clamping screw which extends through the polygonal bore in the hub and carried in a threaded introduced in the center of the shaft journal threaded bore.
  • the carrier has a plurality of concavely curved outer surfaces, and in the inside of each jaw sliding cylinders are mounted radially inwardly projecting, each slide on a concave outer surface or roll and thereby change the distance of the clamping jaws from the center of rotation of the clamping head.
  • each clamping jaw on two sliding cylinders which are arranged at a distance from each other on an outer surface circumferentially movable.
  • the curvatures of the outer surfaces are designed so that all clamping jaws move in a rotational relative movement of the support hub by the same amount in the radial direction.
  • the clamping heads are exactly centered during clamping.
  • each clamping head on its outer side on a flanged wheel, which is mounted on the one hand limited rotatably mounted on the support hub, on the other hand, rotatably connected to each jaw.
  • the rotationally fixed connection between the flanged wheel and the clamping jaws causes their radial expansion during rotation of the flanged wheel by a sleeve.
  • the radial expansion of the jaws is also guaranteed if they do not rest on the inside of the sleeves.
  • the slitting and winding machine shown in detail in Figure 1 is used for winding webs, in particular of plastic films or metal foils, to bobbins.
  • the webs are wound on sleeves 1, which are held at both ends of a retracted into the sleeve 1 chuck 2 during winding.
  • Each chuck 2 is rotatably mounted on a winding lever 3.
  • the rotary drive is an electric motor 4 which is fastened to one of the winding levers 3.
  • the required torque is introduced into the chuck 2.
  • Wound cutting and winding machines must be able to wind on sleeves 1 with different inner diameters.
  • the clamping heads 2 When changing the sleeve format, the clamping heads 2 must be replaced with clamping heads 2 with adapted outer diameter. The replacement of the clamping heads 2 should be possible quickly and without much effort, it is essential that even at high speeds an exact concentricity of the sleeve 1 is guaranteed.
  • a shaft journal 5 is rotatably mounted, on which the clamping head 2 is pushed, which has an adapted designed central bore 6.
  • the clamping head 2 is a so-called expansion clamping head whose outer surface is formed by a plurality of tubular segment-shaped clamping jaws 10 which are mounted radially displaceable.
  • three clamping jaws 10 are arranged circumferentially around the carrier 7.
  • the carrier hub 7 has a plurality of outer surfaces 11, which are curved concavely in cross-section in example 6, on which the clamping jaws 10 are supported.
  • the clamping jaws 10 are each supported by supporting elements which slide or roll on the outer surfaces 11.
  • Gliding cylinders 12 are preferably mounted protruding radially inwards in the inside of each clamping jaw 10, which slide or roll on a concave outer surface 11 and change their spacing and thus also the spacing of the clamping jaws 10 from the center of rotation 13 of the clamping head 2 ,
  • each sliding cylinder 12 is rotatably mounted in a clamping jaw 11.
  • each clamping jaw 10 has two sliding cylinders 12, which are arranged at a distance from each other on a separate outer surface 11 are circumferentially movable. The curvatures of the outer surfaces 11 are so designed that all jaws 10 move in a rotary relative movement of the support 7 by the same amount only in the radial direction.
  • Each clamping head 2 has at its the winding lever 3 facing outside a flange 14, which is mounted on the one hand limited rotatably mounted on the support hub 7, on the other hand rotationally fixed to each jaw 10 is connected.
  • the rotationally fixed connection is effected in the exemplary embodiment in each case by a guide pin 15 which projects into a slide guide introduced into the 10 sliding guide, so that only a radial, but no circumferential relative movement of the clamping jaw 10 is possible.
  • the clamping jaws 11 themselves or at least one sliding cylinder 12 per clamping jaw 11 can be made longer and protrude with its end into an inserted into the inside of the flanged wheel 14 slotted guide to prevent a circumferential relative movement.
  • a disc-shaped cover 16 On the inside of the clamping head 2 is closed by a disc-shaped cover 16 which is screwed by means of screws 17 to the carrier 7. In the center of the lid 16 is a through hole 18 through which a tool for tightening and loosening the clamping screw 8 can be moved.
  • the invention offers the great advantage that clamping heads 2 with different diameters and different immersion depths - ie different clamping head widths - can easily be fastened on the shaft journal 5 for different sleeves.
  • the different clamping heads 2 have a uniform polygon bore 6, so that they can be fastened on the same shaft journal 5.
  • a uniform polygonal connection between the carrier hub 7 and the shaft journal 5 mounted on the winding lever 3 is used for all clamping heads 2.
