Definitions

  • the present invention relates to a device for winding or unwinding continuous, in particular flaking, flexible sheet-like structures, preferably printed products to or from a roll.
  • the ring-shaped winding core in the case that it is driven, is the driven part of a friction gear and the supporting wheels serving as bearings, on which the inside of the winding core rests, are at the same time the driving part of the friction gear.
  • the winding core of the known device has inwardly projecting side flanges, which to a certain extent form a flange with the end faces of the Support wheels, but also the guide wheel interact.
  • the winding core and, in particular, the spacing of its side flanges from one another must be adapted to the thickness of the support wheels and the guide wheel, which in turn cannot be designed as rollers.
  • the thickness of the carrying wheels and that of the guide wheel must correspond and, moreover, the end faces of all wheels must each lie in one plane if they are to meet the side flanges of the winding core of their role as wheel flanges.
  • the winding core in the previously known device for lifting the winding core from the carrying wheels, the winding core must first be lifted perpendicularly at least by the radial dimension of the side flanges before the winding core can be removed in the axial direction. This vertical lifting requires considerable effort, in particular when the winding core is fully wound.
  • the side flanges - as mentioned - have to be adapted to the thickness of the wheels, and on the other hand, the outer surface of the wheels should be adapted to the format of the surface structure to be wound, so that they are as large as possible directly or indirectly on the outer surface of the winding core are supported.
  • the winding core can be purely hollow-cylindrical, i.e. approximately in the form of a flangeless tube section, which facilitates the removal of the winding core and its better adaptation to the width of the fabrics.
  • the idler wheels nor the guide wheel - apart from their interaction with the inside of the winding core - should be able to be dimensioned independently of the design of the winding core, the constant axial position of the winding core still being guaranteed during its rotation.
  • the proposed device has the features specified in the characterizing part of patent claim 1.
  • the winding core also experiences an axial movement component during its rotation, which, depending on the direction of rotation of the winding core and on the side of the steering deflection
  • the winding core either urges the stop arrangement, which fixes its axial position, or it removes the winding core from the stop arrangement, which significantly simplifies the removal of the winding core. A few degrees of angle are sufficient for the steering deflection of the guide wheel.
  • a motor 11 drives a deflection roller 16 of a ribbon conveyor 17 via a chain 12, a countershaft 13, a transmission 14 and a further chain 15.
  • the ribbon conveyor 17 is supported by a rocker-type frame, not shown, which can be pivoted about the axis of rotation of the deflection roller 16 and is always connected to the outer circumference of a winding core 19 by means of a gas spring 18. of a winding 20 being formed thereon urges.
  • the ribbon conveyor 17 leads to the winding, not shown, flexible sheets, respectively. promotes such fabrics when unwinding the roll.
  • a supply roll 22 for a Winding belt 23 driven which in turn passes through the ribbon conveyor 17 in the area of its contact point on the winding core 19 or on the winding 20 and is wound up in the course of winding up the sheet-like material (not shown) supplied by the ribbon conveyor, or when the winding 20 is unwound the supply roll 22 is wound up.
  • a further chain 24 leads from the countershaft 13 to a winding gear 25 with an automatically infinitely variable transmission ratio.
  • a further chain 26 leads to two support wheels 28, 29, which are connected to one another via a chain 27 and rotate in the same direction, on which the winding core 19 is mounted and which - if driven - drive the winding core 19 in a frictional manner in the same direction of rotation.
  • the support of the winding core 19 is supplemented by an essentially freely rotatable guide wheel 30, which can be raised and lowered and, in the lowered position, also interacts with the inside of the winding core 19 and then not only an unwanted lifting of the winding core 19 from one of the carrying wheels 28, 29 prevents, but can also contribute to increasing the frictional engagement between them and the inside 19a of the winding core 19.
  • the wheels 28, 29 and 30 thus ensure a central position of the winding core 19 in all cases.
  • FIG. 2 shows the carrying wheel 28 and the guide wheel 30, which is shown in solid lines in the engagement position with the smooth inside 19a of the winding core. Part of the outline of the winding 20 is shown in dash-dot lines.
  • the support wheel 28 is wedged on a shaft 31, which in turn is rotatably mounted in a bearing housing 34 in two roller bearings 32, 33.
  • the bearing housing 34 is fixedly flanged to one side of a vertical side wall 35 of the machine frame, the end of the shaft remote from the supporting wheel 28 passing through this wall 35 and having the chain wheels 36 and 37 receiving the chains 26 and 27 wedged.
  • the bearing and arrangement of the carrying wheel 29 corresponds to that of the carrying wheel 28.
  • the guide wheel 30 is also keyed on a shaft 38, which is first rotatably supported in a bearing housing 40 via a spherical roller bearing 39.
  • the bearing housing 40 is flanged onto an annular plate 41, which in turn (see FIGS. 3 and 4) is anchored to a carriage 42.
  • This carriage 42 which is highlighted in FIG. 3 by a thick border, is displaceably guided by ball bushings 43 (FIG. 2) on two parallel columns 44 and 45, so that the steering axis of the bearing housing 40 is thus radially displaceable with respect to the winding core 19, specifically in one Recess 44 'present in the side wall 35.
  • a fluidic unit 45 ′ is used to raise and lower the bearing housing 40, the piston rod 46 of which is articulated in the middle of the slide 42 via a universal joint 47 (FIG. 2).
  • the carriage 42 is substantially U-shaped. It encompasses a bearing plate 48, which in turn is held between the legs of the carriage 42 by pins 49, 50 (FIG. 4) which are flexible on opposite sides so that they do not line up with the columns 44, 45 with respect to the carriage 42 parallel direction, but only at right angles to it.
  • the piston rod 52 of a further fluidic unit 53 is articulated on the plate 48 at 51, the cylinder of which is articulated at 55 at the end of an arm 54 projecting laterally from the carriage 42.
  • a pin 56 is anchored on its side opposite the articulation point 51 and engages in a guide piece 57 fastened to the slide 42.
  • Another spherical roller bearing 58 is mounted in the bearing plate 48, in which the end of the shaft 38 remote from the guide wheel 30 is mounted. Since the bearing plate 48 and thus also the self-aligning roller bearing 58 can be displaced transversely to the direction of the columns 44, 45, the shaft 38 can be pivoted within a limited angular range around the center of the pivot roller bearing 39, or, in other words, this center corresponds to a steering axis 59 , around which the guide wheel 30 can be deflected. 4, the outline of the undeflected guide wheel 30 is shown in full line, whereas the outline is dash-dotted in the two possible end positions of the deflection.
  • the winding core 19 is placed on the carrying wheels 28, 29 in such a way that the end faces of the winding core 19 assume the position indicated by dash-dotted lines in FIG. 4 with 19 '.
  • the winding core 19 is then set in rotation by the support wheels 28, 29 such that the inside of the winding core, on which the guide wheel 30 acts, moves in the direction of the arrow 60.
  • the winding core 19 is not yet exactly positioned in the axial direction. It is now sufficient to move the bearing plate 48 upward in FIG. 4 so that the axis of rotation of the guide wheel 30 indicated by dash-dotted lines is pivoted counterclockwise by a few degrees about the steering axis 59, the guide wheel 30 receiving a corresponding steering deflection.
  • the guide wheel 30 now gives the winding core 19 a component of movement in the direction of the arrow 61 in FIG. 4.
  • the winding core 19 thus migrates towards the side wall 35 during rotation, that is to say to its correct axial position.
  • the correct axial position is now determined by an arc-shaped stop rail 62 which (see FIG. 2) is fastened to the bearing housing 40 of the shaft 38 and can therefore be raised and lowered with it, the stop rail being concentric with the winding core placed thereon.
  • the stop rail 62 can also be arranged displaceably and fixably along the bearing housing 40.
  • the An Impact rail 62 can also be provided freely rotatable stop rollers, whose axes of rotation are directed radially to the wound core.
  • the guide wheel 30 with its shaft 38 is always freely rotatable and the steering deflection of the guide wheel 30 is achieved by acting on the unit 43, the fact that the steering axis 59 is outside the center plane of the guide wheel 30 lies, are used to effect its steering deflection in other ways.
  • Such an embodiment is outlined in FIG. 5.
  • the end of the shaft 38 passing through the side wall 35 is mounted here via a roller bearing 63 in a bearing sleeve 64 which can be displaced transversely to the columns 44, 45 in a manner similar to the bearing plate with respect to the slide 42.
  • the shaft 38 is extended via the roller bearing 63 and carries a part 66 of an electromagnetic brake 67 via a ball bearing 65, which part is secured against rotation by a guide bracket 68 overlapping the slide 42 without being prevented from being displaced transversely.
  • the other part 69 of the brake 67 is wedged on the free end of the shaft 38 (on the right in FIG. 5).
  • the shaft 38 remains axially parallel to the axes of rotation of the support wheels 28, 29 due to the action of the pins 49, 50, and no axial movement component is imparted to the winding core 19.
  • the brake 67 is actuated, the braking of the guide wheel 30 causes it to follow the winding core 19 rotating in the direction of movement 60 and thus causes the steering deflection about the steering axis 59.
  • the braking force is to be dimensioned such that the guide wheel 30 is not prevented from rotating, but is only inhibited.
  • the guide wheel 30 is again axially parallel to the support wheels 28, 29.
