Definitions

  • the invention relates to sleeve receiving body for the axleless tensioning of winding sleeves made of hard or soft materials in axially exciting reels and unwinds for material webs that can be inserted into the winding sleeve on both sides, consisting of a device for receiving insertable clamping heads with driver devices, a conical part to prevent a vertical displacement of the winding tube and a torque transmission device on the tube holder body, which represents an annular surface.
  • Mechanical or pneumatic expansion shafts such as those from Tidland Machine Compagny, Camas, USA or Schlumpf AG Steinhausen / Switzerland or Double E. Compagny Inc. Brockton, USA are inserted into the winding tube from the side and then enlarged in diameter, so that their outer surfaces press radially against the inner surface of the winding tube and thus enable the transmission of the torque. Due to the large contact area of the expansion shaft with the sleeve, gentle treatment of the sleeve with safe transmission of the torque is possible. These expansion shafts are heavy, unwieldy and expensive to manufacture and, if they are inserted into the sleeve on both sides, require wide sweeping coils.
  • Another known device transmits the torque from the machine to the winding sleeves by means of conical clamping heads which are pressed into the winding sleeves on both sides.
  • the cones of the clamping heads are often roughened on their surface or provided with radial teeth.
  • the torque is transmitted by the teeth of the cones penetrating into the edge of the sleeve, which is usually considerably damaged and expanded when using cardboard winding sleeves. After a few rolling operations, the cardboard winding tube becomes unusable due to abrasion on the edges.
  • This method can be used when the cardboard winding tubes are used once in companies that do not significantly interfere with abrasion and dust, but not if no dust is allowed to arise during winding or unwinding, such as e.g. B. in the photo industry.
  • the torque is transmitted essentially radially from the mandrel to the cardboard tube with a weakly conical part, the smallest diameter of which is equal to the inside diameter of the cardboard tube.
  • the sleeve material is compressed from the inside by the weakly conical part.
  • a collar-shaped projection is provided which compresses the tube material from the outside. From this version it can be seen that the sleeve edge is clamped between the two cones and the torque is transmitted at least in the case of new sleeves.
  • the edge of the sleeve itself becomes conical, so that additional means such as radial projections or expandable mandrels must be used.
  • a winding tube receiving body with a conical and a cylindrical part which is pressed into the winding tube up to a collar.
  • the winding tube holder body only has the task of supporting the winding tube in a centered manner and is mounted on ball bearings.
  • the web wound on the winding tube is driven or braked by driven rider rollers which rest on the web.
  • the invention has for its object to find an easy-to-use device that can be used without causing abrasion and dust in axially exciting reels and unwinds, is inexpensive and can also serve to transport the winding material without damaging the winding tube and To carry winding material from and to the processing machine also with hoists.
  • the sleeve receiving body according to the invention can also be produced very inexpensively in large quantities and only costs one Tenth of the price of the comparable mechanical or pneumatic expanding winding device.
  • the sleeve receiving bodies can be made from a wide variety of materials, such as made of plastic or metals such as zinc, aluminum, steel, by casting or turning and possibly subsequent mechanical processing.
  • the sleeve receiving bodies can also be used to transport the webs into and from the processing machine.
  • the sleeves are protected from damage at the mostly protruding, very sensitive ends and the material to be wound can be safely removed. Damage caused by pressure and without being touched.
  • the advantageous design of the tube holder body with a smaller outside diameter than the inside diameter of the winding tube allows easy and quick insertion into the tube and also the extraction.
  • this cylindrical part of the tube holder body bears the weight of the material to be wound, whereby the tube bends somewhat. It was found that the play between the sleeve and the receiving body can be 0.25 to 0.5 mm, so that the corresponding diameters differ by 0.5 to 1 mm. No tools are therefore required to insert and remove the sleeve receiving body.
  • the conical widening of the sleeve receiving body between the cylindrical part and the driving end face centers the winding tube to the axis of the clamping head and thus prevents the winding sleeve from moving vertically or working against the sleeve receiving body when the axial thrust of the clamping heads acts and the material to be wound is unwound or unwound.
  • This inventive design of the sleeve receptacle avoids the possibility of abrasion or dust formation.
  • the torque of the processing machine is transmitted via the clamping heads and the sleeve receiving body to the end ring surfaces of the winding tube.
  • the sleeve receiving body has a corresponding circular surface. It is astonishing that even a smooth circular ring surface can transmit considerable torques.
  • the end faces of the sleeve receiving body that transmit the torque can be coated with a friction-increasing agent, glued, vulcanized or applied in another way.
  • a friction-increasing agent is different types of rubber, plastic discs or other materials with rough surfaces.
  • the end face of the core holder body can be provided with a toothing, creasing or with pins, the teeth or grooves being directed radially and towards the end surface of the winding core and thus pressing into the end face of a cardboard winding core used.
  • the driving end face forms a positive toothing, so that the transmission of even the highest torques is possible and material webs of the order of several tons in weight can be processed safely.
  • the winding tube 1 shows an embodiment of a tensioning device.
  • the winding tube 1 carries the winding material 2, which can consist of a material web of any length and width and is to be unwound from the winding tube 1 or wound onto it.
  • tube receiving bodies 3 are inserted from both sides. In this way, the end faces of the winding tube are protected.
  • the tube holder body 3 is provided with a device into which clamping heads 4 of the processing machine or holding heads of the transport or storage means are inserted axially from both sides, so that the winding tube is not damaged and handling is possible without touching or damaging the winding material.
  • the axial force is transmitted via the circular surfaces 8 of the tube holder body 3 to the end faces 8 of the winding tubes while exerting the axial clamping forces 6.
  • Fig. 2 shows one side of the clamping device on an enlarged scale.
  • the material to be wound 2 is carried up or down on the winding tube 1 via the tube receiving body 3 by the clamping heads 4.
  • the clamping head 4 engages with a round conical part 10 in corresponding central conical bores of the sleeve receiving body 3.
  • the material web 2 is now centered and supported on an imaginary axis.
  • a round cone 10 is not sufficient to transmit very high torques, so that additional means are required.
  • a round disk 5 with one or more driver bolts 11 is attached to the clamping head 4, which in turn engage in bores 12 of the sleeve receiving body 3 and allow safe torque transmission to the sleeve receiving body 3.
  • the clamping head 4 can be equipped with a square cone, which engages in a corresponding recess in the sleeve receiving body and takes on both the task of centering and that of torque transmission.
  • a polygonal cone up to a round cone 10 with axial grooves can be used, depending on the type of task with regard to torque transmission and centering (not shown).
  • FIG. 3 shows in section A of FIG. 2 the force transmission point from the sleeve receiving body 3 to the end face 8 of the winding tube 1.
  • This transfer surface 8 on the sleeve receiving body 3 can be smooth or provided with radially extending grooves or teeth 14.
  • pointed elevations in the direction of winding sleeve 1 could be attached to the ring surface 8, which penetrate into it when axial pressure is applied and when a cardboard winding sleeve 1 is used.
  • the end face 8 can also be provided with a friction-increasing material in order to improve the non-positive connection between the winding sleeve 1 and the sleeve receiving body 3 if high torques are to be transmitted.
  • the slope 7 shown centers the winding tube 1 and prevents vertical beating during the winding process.
  • a cardboard winding tube 1 can be easily compressed by the bevel 7, but the pulling out and insertion of the tube receiving body 3 is not made difficult.
  • metal winding sleeves 1 they can be slightly tapered on the inside, so that they can easily be pushed onto the conical part of the sleeve receiving body 3.
  • the cylindrical part 9 of the sleeve receiving body 3 takes up the weight of the webs, the winding tube 1 resting against the sleeve receiving bodies 3.
  • the gap width 13 must therefore not be chosen too large and should preferably be 0.25 to 0.5 mm, so that the weight of the material web can be absorbed without substantial deformation of the winding tube 1 and at the same time an easy insertion and removal of the tube receiving body 3 is possible in a relieved state.
  • the sleeve receiving body 3 can be made from a variety of materials as needed. If 2 cardboard tubes 1 are used for winding webs, it is advantageous to produce the tube receiving bodies from hard plastics or from metals.
  • the torque transmission surface 8 of the sleeve receiving body 3 is expediently made of softer material, such as e.g. Hard rubber, Vulkolan, polyurethane and others, or provided on its torque transmission surface 8 with such a material ring 14.
