Definitions

  • the invention relates to a device for unrolling or rolling up web-like or tape-like materials such as paper, foils, textiles or the like.
  • motor-driven winding shafts that are rotatably supported on at least one side in sliding bearings and that can be individually moved and positioned along a self-contained guideway are.
  • the winding shafts are individually movably guided and positioned in a rigid guide frame. You will need drive motors for the winding process and for positioning. In the known device, only short free web lengths occur in an advantageous manner, a flying reel change and thus a continuous mode of operation being possible nonetheless. With the great variability of the control and individual positioning of the winding shafts, the design and costs are not insignificant.
  • At least one rotationally drivable guide drum forming the guideway is provided, on which the sliding bearings are freely displaceable, that the sliding bearings are provided on the guiding drum and can be operated independently of each other and that the axis of rotation of the in each case a winding shaft which is fixed to a definable winding position of the guideway is provided with a correspondingly actuated holding device which fixes the machine.
  • At least the winding shafts involved in the winding process and the removal process of the finished wound roll can also be moved and positioned independently of one another in this structurally simpler device.
  • Positioning drives individually assigned to the individual winding shafts are not necessary, since the positioning drives fixedly arranged on the machine frame can shift any or several of these winding shafts.
  • the guideways designed as guide drums and the machine frame serving as the bearing point can be constructive be very simple. Nevertheless, a variable and individual winding process is possible, in which long free web lengths can be avoided, which can lead to wrinkles and a course of the edges with stretchable materials.
  • a single, rigid guide drum is arranged on an outwardly extending drive shaft in the lateral region of the winding shafts outside the path of the materials to be wound. This simplifies the drive device for the single guide drum in a special way.
  • a more variable construction is achieved in that a single guide drum consisting of an inner and an essentially concentric outer area is arranged in the lateral area of the winding shafts outside the path of the materials to be wound, that one area is designed to be drivable independently of the other area, that the sliding bearings are preferably guided so that they can move freely between the areas and that on each sliding bearing these are optionally provided with fixing devices which fix the inner or outer area.
  • the inner ring can be machine-fixed and the outer ring drivable, for example via an externally acting drive.
  • Those sliding bearings that have to be positioned stationary can be fixed on the fixed inner ring, while the sliding bearings to be transported are fixed on the rotating outer ring.
  • the latter In order not to overload the one-sided bearing points due to the great weight of a completely wound roll, the latter is guided on a guide segment which essentially extends from the winding position to a removal position for rolled-up material and which guides the free end of the winding shafts mounted on one side in sliding bearings. When the removal position is reached, it can be pivoted or moved to enable easy removal of the roll.
  • At least one guide gripper which is pivotally driven about the axis of rotation of the guide drum, is expediently designed to be adjustable radially to this axis of rotation for gripping one winding shaft in each case.
  • the guide gripper or grippers are moved axially against the winding shaft located in the winding position, the end of the guide gripper which grips the winding shaft being preferably designed as a half bearing, while the counterbearing is formed on one winding shaft side by the guide drum and on the other winding shaft side by the guide segment will.
  • two guide grippers in the area of the two ends of the winding shafts have proven to be particularly favorable.
  • the winding shafts are rotatably supported on both sides in sliding bearings guided on two guide drums.
  • the guide segment and the guide grippers can thus be omitted. Both the unwinded and the wound winding shafts are safely supported on both sides in every position.
  • the two guide drums are arranged on a common, continuous drive shaft. If the continuous drive shaft in the middle area between the two guide drums proves to be disruptive, these can also be arranged on separate drive shafts, each of which runs outward and are synchronously coupled to one another in terms of drive, in particular via a coupling shaft arranged parallel to the axis of rotation, which is connected to the two separate drive shafts or is connected to the two guide drums via synchronous drives.
  • the space between the two drums can thus be fully utilized, that is to say that larger rollers can be formed with a relatively small diameter of the guide drum.
  • the guide drums each consist of an inner and an essentially concentric outer area, that an area is designed to be motor-driven independently of the other area, and that the sliding bearings are preferably freely displaceable between these areas are guided and that on each sliding bearing this is optionally provided on the inner or outer fixing fixtures.
  • One of the two areas preferably the inner area, can be fixed in a machine-fixed manner, or both areas can be designed to be driven by a motor independently.
  • the fixing to one of these areas in the winding position can serve as a holding device that fixes this winding shaft in a machine-fixed manner.
  • a separate holding device can thus advantageously be omitted.
  • the optional fixation on the inner or outer area allows a large variability of independent movements of the individual winding shafts. This can be increased further in that the inner and / or outer regions are additionally designed to be drivable independently of one another.
  • the already described advantages of one-sided mounting of the winding shafts in a guide drum consisting of two areas naturally occur additively here.
  • the winding shafts are expediently releasably connected to the sliding bearings from both sides, so that the rollers can be removed together with the winding shafts or corresponding areas of the winding shafts.
  • Axles which are axially displaceable and can be displaced in axial engagement with the winding shafts are particularly suitable for this purpose, at least the sleeve on the drive side forming a rotationally fixed connection.
  • the holding device which fixes the axis of rotation of the winding shaft in the winding position can preferably consist of a bearing device which can be moved at the end against the rotating end of the winding shaft and, if required, additionally from a machine-fixed holding device for the opposite end. With the holding device actuated and the locking devices released, the drum or the drums can rotate independently of the fixed position and can move other winding shafts. As already stated, such a holding device can also be dispensed with if the winding shafts are supported on both sides and the guide drums consist of two areas.
  • these sliding bearings are provided with guide rollers which roll on the guide drum or the guide drums.
  • Each sliding bearing is preferably provided with at least 8 guide rollers, each with a guide track in pairs grasp the guide drum or support yourself in pairs on parallel guideways.
  • Friction brakes or locking elements which engage in structured braking surfaces are suitable as locking devices.
  • a machine frame 10 consists of a drive side 11, a bearing side 12 arranged parallel thereto, and a connecting part 13 between the drive side 11 and the bearing side 12. Further areas required for the stability of the machine frame 10, such as a support part are not shown for simplification.
  • a guide drum 14 is drivingly connected to a hollow shaft 15, which extends outward from the guide drum 14 through the drive side 11. On the outside it will driven by a drive motor 16.
  • the guide drum 14 has a double T-profile on average, the outer, curved profile surface 17 forming a guide track. In the exemplary embodiment, this guideway is circular, but it can also be oval or a polygon with rounded corners for special purposes.
  • sliding bearings 18 are freely displaceably supported by guide rollers 19. These are eight of these guide rollers 19, each of which enclose the profile surface 17 in pairs in the region of the outer edges thereof. At both longitudinal ends of the sliding bearing 18 holding plates 20 are attached, which carry the guide rollers 19. Since these holding plates 20 overlap the profile surface 17, the sliding bearings 18 are thereby fixed in the axial direction. To reduce friction, the contact paths between the holding plates 20 and the profile surface 17 can also be provided with rollers in a manner not shown.
  • angular locking devices 21 extend to the inside of the profile surface 17. There they are provided with a friction lining 22 which is pressed against the inside of the profile surface 17 when the locking devices 21 are actuated, so that the respective sliding bearing 18 is fixed to the guide drum 14.
  • the guide rollers can for example also be supported in pairs on the parallel inner sides of the guide drum 14.
  • the locking devices can in principle also act on another surface of the guide drum 14 which acts as a friction surface.
  • the actuation can take place pneumatically, for example, or via eccentrics.
  • Winding shafts 23 are rotatably mounted in the sliding bearings 18 and can be set in rotation by drive motors 24 flanged to the outside on the sliding bearings 18.
  • Winding sleeves 25 can be pushed onto these winding shafts 23 from the free end, onto which the material to be wound can be wound and laterally pushed out together with the respective winding sleeve as a finished roll.
  • a drive shaft 26 runs through the hollow shaft 15 and is mounted in a bearing 27 at the end on the bearing side. It is driven from the outside of the drive side 11 by a drive motor 28.
  • two guide grippers 29 are adjustably mounted radially to the axis of rotation of the drive shaft 26. The adjustment can, for example, in a manner not shown Form pneumatically or via servomotors.
  • the outer ends of these guide grippers 29 are designed as half bearings 30 and can accordingly encompass the winding shaft 23 on one side, on both sides of the winding tube 25 positioned on it.
  • a guide segment 31 is pivotally mounted about a stopping point 32.
  • This guide segment 31 is essentially designed as a 1/4 circle segment which has a curvature corresponding to the guide path of the winding shaft around the guide drum 14 and can be determined parallel to this guide path.
  • the free end of a winding shaft 23 can be brought into abutment against this guide segment 31 by means of the guide gripper 29 arranged at the corresponding point, so that it represents a counter bearing and the winding shaft can be guided along this guide segment 31.
  • a holding device 33 which has a bearing device 34 designed as a tip bearing that can be moved against the free, rotating end of the winding shaft.
  • a holding device (not shown or not shown in the drawing) for the drive motor 16 or the sliding bearing 18 of the winding tube 25 in the winding position is provided. In this way, a winding tube can be stored on both sides in the winding position independently of the guide drum 14.
  • This winding position is seen from the bearing side 12 in the horizontal plane of the drive shaft 26 to the right of the latter, while the removal position is located vertically below this drive shaft 26.
  • the web or band-shaped material 35 to be rolled up is located in a manner not shown on a supply roll and is fed to a motor-driven winding shaft which is in the winding position via guide rollers 36, only one of which is shown schematically in FIG. 4. It is essential here that the guide rollers are arranged close to one another or the last guide roller 36 is arranged close to the winding shaft in the winding position in order to avoid free web lengths. From a certain roll diameter of the resulting roll, this winding shaft is gripped by the guide grippers 29, the holding device 33 is released and the further rotating winding shaft moves downward along the guide track, so that there is no collision between the enlarging roll and the guide roller 36. The free path length can always be kept to a minimum.
  • the web-shaped material 35 is divided into three individual webs in the region of the guide rollers 36 by a longitudinal cutting device, so that three rolls are produced from one web.
  • a longitudinal cutting device is described in the prior art specified at the outset. Of course, such a subdivision can also be omitted or another longitudinal division.
  • the subsequent winding shaft is pushed into the winding position by actuating its locking devices 21 and by rotating the guide drum 14. If it reaches this, it is gripped by the holding device 33, and the locking devices 21 can be released again.
  • This winding shaft is now accelerated to the required winding speed with the aid of its drive motor 24.
