Definitions

  • the invention relates to a device for winding material webs on winding tubes with mutually aligned, rotatably mounted support pins in a machine frame, which at their mutually facing ends have mandrels for moving into the winding tubes and for bracing them, and each with a retaining, axially are displaceable bearing sleeve, and with a drive for the reciprocating process at least one of the opposing trunnions.
  • turret winder with circumferential drive in which a shaft mounted in the machine frame is provided in pairs with opposing and offset by 180 degree support arms, at the free ends of which aligned trunnions are arranged between them the inner ends of the mandrels attached to the winding sleeves are held.
  • the trunnions In order to put the winding tubes on the mandrels of the rotatably mounted trunnion and to be able to remove the finished wound rolls, the trunnions must be axially displaceable so that they can be moved apart so far that the tubes and Free the winding rolls from the thorns.
  • a device of the type mentioned in which the supporting pin supporting the mandrel is rotatably mounted in a bearing sleeve which is axially displaceably guided in a bore of a supporting arm of a roller changing device, so that the supporting pin is extended and so can be drawn far that the mandrel almost completely immersed in the bore of the support arm.
  • This known device may work satisfactorily if the width of the winding tubes and winding rollers corresponds approximately to the distance between the support arms, so that the trunnions for mounting the winding tubes and removing the winding rollers only have to be axially displaced by a length which is one or two times the length of the Match thorns.
  • the diameter of the mandrel or adapter piece must not be greater than the diameter of the bearing sleeve in order to be able to immerse the mandrels in the holes in the support arms when the support pins are moved apart. If larger mandrels or adapter pieces were used, it would no longer be possible to roll rolls which, with their width, exploit the full distance between the support arms, because the usable distance would then be reduced by the length of the mandrels.
  • the object of the invention is therefore to provide a device of the type mentioned, which allows the winding of different width winding rolls without inadmissible deflections of the support pins should be feared in particular when pressure rollers or pressure tapes act on the circumference of the winding rolls.
  • this object is achieved in a device of the generic type in that the trunnion is axially displaceable but non-rotatably guided in the bearing sleeve, which in turn is axially displaceable but non-rotatably guided in a bearing bush which is rotatably mounted in the machine frame.
  • the trunnion can be made thinner without fear of inadmissible deflections, since it is guided in the bearing sleeve, which is also designed to be extendable, so that the free length of the trunnion can be reduced considerably without thereby reducing the distance, by which the mandrel can be extended.
  • the trunnion and the bearing sleeve are telescopically, so to speak, extendable from the bearing bush rotatably mounted in the machine frame, so that the mandrels carrying the winding sleeves or winding rollers can be extended to different lengths for adaptation to winding sleeves of different lengths, the free length of the trunnions being guided by their guide in the bearing sleeves, which are able to absorb larger bending forces due to their diameter, are reduced.
  • the diameter of the trunnions can be kept smaller than the smallest diameter of the winding sleeves which can be fastened on their mandrels
  • pressure rollers or pressure tapes can be used for winding winding rollers of different widths, the width of which is adapted to the greatest possible width of the winding rollers.
  • the support pin is expediently mounted in a ring which is connected to a spindle nut into which a spindle mounted in the machine frame and provided with a rotary drive and running parallel to the support pin is screwed.
  • a spindle drive With this spindle drive, the trunnion can be moved in a simple manner.
  • the support pin is provided with an axial bore in which an actuating rod for the clamping device of the mandrel is guided, and that the actuating rod can be moved back and forth by a piston which is in one end with the supporting pin connected cylinder is guided, which is provided for the supply and discharge of pressure medium with a rotary union.
  • the spindle nut forming a retaining pin for the bearing ring is expediently guided in a longitudinal slot of a guide tube which is firmly connected to the machine frame.
  • This The guide tube is also a protective tube for the trunnion.
  • the bearing sleeve is connected at the end to disks which are provided with central bores for the passage of the trunnion and that at least one compression spring is clamped between the outer edge of the inner disk and the bush, both of which push apart seeks.
  • This configuration ensures that when the trunnion is retracted into the space designated for holding the winding sleeves, the bearing sleeve is first extended before the trunnion extends out of the bearing sleeve over the remaining insertion distance of the mandrel.
  • the possible displacement path of the bearing sleeve relative to the bearing bush is limited by stops. These stops are formed by the disks.
  • the edge of the outer disk of the bearing sleeve is expediently supported as a stop on the end edge or the outer end face of a feather key screwed thereto.
  • a support wall of the machine frame is connected on its inner side to a protective tube, the diameter of which corresponds approximately to the diameter of the inner disk and which is so long that the mandrel can be fully inserted into it.
  • a protective tube the diameter of which corresponds approximately to the diameter of the inner disk and which is so long that the mandrel can be fully inserted into it.
  • the mandrel is expediently interchangeably attached to the inner end of the trunnion.
  • the mandrel can thus consist of an adapter piece that has different diameters of the winding tubes is adjusted.
  • the diameter of the protective tube is dimensioned such that mandrels and adapter pieces of the largest diameter can also be inserted therein.
  • the invention can be implemented in a centrally driven reversing winder, in which two supporting pins aligned in pairs with each other with these bearing sleeves and bearing bushes are arranged in opposing disks, which are rotatably mounted in corresponding circular recesses on opposite side walls of the machine frame.
  • the frame-shaped machine frame 1 has two side walls 2, 3, each of which is provided with a cutout 4.
  • the two side walls 2 and 3 have an annular extension 4 ', which is encompassed by the collar 5 of a hollow disc 6 with the interposition of a ball bearing 7.
  • the collar 5 is occupied by external teeth 5 'which engage an intermediate wheel 8.
  • the latter meshes with a pinion 9 of a motor 10 which is firmly connected to the frame 1.
  • the motor 10 is only on one side of the frame 1, while on the side of the frame opposite the motor a pinion 9 corresponding second pinion 9 'is provided, which is connected via a synchronous shaft 11 to the rotary motor 10.
  • a drive motor 12 can also be seen from FIG.
  • This drive motor 12 serves to drive the winding head 13, the winding head 14 lying opposite the winding head running freely.
  • Another drive motor 15 is provided on the other side of the frame 1. This motor serves to drive the winding head 16, wherein the winding head 17 opposite this winding head 16 can also be freely rotated.
  • a traversing motor 18, 19, 20 and 21 is assigned to each winding head 13 to 17. Apart from the drive of the head 13 by the motor 12 and the drive of the head 16 by the motor 15, all end windings 13 to 17 are of identical design. For this reason, only the end winding 13 assigned to the drive motor will be explained in more detail below with reference to FIG. 2.
  • the drive motor 12 is flanged to the outer wall 22 of the hollow disc.
  • a toothed belt pulley 25 is placed on the motor shaft 24 between the two walls 22 and 23 of this hollow disk 6.
  • the toothed belt 26 of this toothed belt pulley 25 engages around a ring gear 27 which is placed on a retaining ring 28.
  • the retaining ring 28 is connected via ball bearings 29 to a carrier 30 which consists of two parts and is fixedly connected to the walls 22 and 23.
  • the retaining ring 28 encompasses a sleeve 31 which has a groove 32.
  • a key 33 engages in this groove and is screwed to the retaining ring 28.
  • the sleeve 31 is consequently axially displaceable relative to the retaining ring. This axial displacement is facilitated by two annular bearings 34 and 35.
  • two ball bushings 36 and 37 are inserted on the end face, which carry a holding pin 38 called a sleeve.
  • the latter has a groove 39 running in the axial direction, into which a feather key 40 engages.
  • the key 40 is fixed screwed to the sleeve 31.
  • the groove 39 is not continuous, it ends on the right-hand side of the sleeve 38 at point A in relation to the figure.
  • the sleeve 38 has a central bore 41 through which a rod is passed.
  • This rod rests on its end protruding from the sleeve on the right-hand side against one leg of a tensioning lever 43, the other leg of which rests against a tensioning part 44 of an adapter piece 45. If the rod 42 is consequently moved to the right, the tensioning lever 43 presses against the tensioning part 44 of the adapter piece 45, as a result of which the sleeve 46 pushed onto the adapter piece 45 is tightened.
  • the rod 42 is connected at its left end to a piston 47 which is slidably mounted in a housing 48. The piston is moved by blowing compressed air into the cylinder chamber 50 via the rotary connection 49. The piston 47 is reset via compression springs 51.
  • the housing 48 is seated on the left end of the sleeve 38.
  • the sleeve 38 is encompassed by a bearing 52 which is held by a holder 53.
  • This holder is connected to a threaded nut 54 which projects through the slot 55 to the outside of a protective tube 56 connected to the carrier 30.
  • a threaded spindle 57 is screwed into the threaded nut 54 and is rotatably mounted at one end in a bracket 58 connected to the protective tube 56 and at the other end in the carrier 30.
  • a toothed belt pulley 59 is seated on the threaded spindle 57 and is connected to the belt pulley 61 of the travel motor 18 via a toothed belt 60.
  • This traversing motor 18 is firmly connected to the left wall 22 of the hollow disc 6.
  • the sleeve 31 has a cover 62 and 63 on each of the two end faces. This cover is intended to prevent the ball bushings 36 and 37 as well as the groove 32 and the bearing 35 Add dirt.
  • the cover 63 closes a protective tube 64 connected to the carrier 30 towards the front.
  • a compression spring 65 is provided, which is supported on the one hand on the retaining ring 28 and on the other hand on the cover 63.
  • the traversing motor 18 is switched on in such a way that the threaded nut 54 moves to the left in the direction of arrow B. This also moves the quill 38 to the left. The point A, the groove 39 reaches the key 40 and lies against it. During the further movement of the sleeve 38 to the left, the sleeve 31 is consequently moved to the left together with the two covers 62 and 63 via the parallel key 40.
  • the inner diameter of the protective tube 64 is dimensioned such that even with the largest possible adapter piece 45 it can move into the interior of the protective tube 64. The previously supported winding roll 66 is then moved down.
  • the extension movement of the sleeve 38 and the extension of the sleeve 31 supporting the sleeve are then carried out in an analogous manner.
  • the drive motor 12 can then be switched on, causing the quill to rotate to form a new winding roll.
  • each finished winding roller 66 is generally removed from the winding device when it has the lower layer shown in FIG. 1.
  • a new winding roll 67 is already formed by the two upper winding heads 16 and 17.
  • the rotary motor 10 is switched on, so that the hollow disc 6 is rotated relative to the fixed frame 1 until the winding heads 13 and 14 shown in FIG have shown upper winding heads 16 and 17 rotated by 180 degrees.
