Definitions

  • the invention relates to a rolling device for winding rolls, with a bearing element, two arranged on the bearing element supporting elements for two-sided rotatable mounting a winding roll, wherein the two support elements are mounted so movable along the bearing element, that changes relative to each other the movement between the two support elements between them , and a drive device for moving the two support elements along the bearing element.
  • Material webs in particular paper webs in the paper processing industry, are generally delivered in the form of large, heavy winding rolls and stored. When processing such material webs on appropriate machines, these webs are removed from the winding rolls.
  • These processing machines are therefore provided with corresponding unwinding devices, in which the winding rollers are rotatably supported on both sides on two bearing elements arranged on a bearing element. In this case, usually the winding roll during unwinding axleless between the two support elements clamped and held by these.
  • the support elements are mounted on the bearing element towards and away from each other movably.
  • a rolling device for large paper rolls which has a frame with four stands and two side rails and at least one rolling bar and two support arms, each with a clamping head.
  • the support arms are horizontally movable transversely mounted on the rolling bar and coupled together via a common threaded spindle such that a first drive for a common opposite transverse displacement of the support arms and a resulting change in their distance from each other for receiving bobbins with different width and a second drive for a common rectified transverse adjustment of the support arms without changing the distance from each other for relative positioning of the winding roll in the processing machine provides.
  • both sides of the frame traction means preferably in the form of ropes, belts or chains, provided which are attached to two spindle nuts of a second horizontally arranged threaded spindle, so that the rolling bar is suspended on the frame via the traction means.
  • the rotation of this second threaded spindle takes place by a third drive.
  • the EP 0 289 749 B1 and the corresponding one US 4,895,314 A disclose a device for unwinding a web of material from a roll, in particular a large paper roll for the paper processing industry.
  • this known device For rotatable mounting of a winding roll, this known device has two support arms, which are mounted together on a pivot shaft.
  • this known device is also provided with a drive device which has a threaded spindle, by means of which the support arms are movable in the transverse direction.
  • a Swivel drive for pivoting the support arms about the pivot shaft and a further drive provided to move the pivot shaft together with the support arms horizontally in the web running direction.
  • a similar rolling device for large paper rolls is described, which comprises two support arms which are mounted together on a pivot shaft.
  • the support arms are provided with clamping heads, which are designed to be retractable to accommodate new bobbins can.
  • the DE 42 19 518 A1 discloses a device for feeding roll-shaped material to an adhesive preparation station.
  • This known device which is provided in particular for receiving unrolling large paper rolls, has a frame with at least four stands, which are interconnected by two longitudinal members. Between the longitudinal members at least one traverse movable in the transverse direction is provided on the two support arms are arranged horizontally transversely movable by means of two trolleys.
  • the known unwinding devices require a rather complicated drive device in order to be able to realize all desired adjustment functions.
  • the invention has for its object to realize in a device of the type mentioned, the drive device with a simple construction, which nevertheless offers all adjustment options.
  • the solution according to the invention provides a mechanically simple and cost-effective design of the drive device with full functionality of a so-called pick-up unwinding, which thus offers all possible adjustments.
  • This is inventively achieved in that at least one traction means is arranged on the bearing element and mounted movably along the bearing element and at least one support element optionally moves along the traction means or can be arranged in relation to this stationary.
  • at least one engagement means is provided on that support element, which releasably locks the support element on the traction means. This results in a mechanical anchoring of the support element on the traction means, which causes a stationary arrangement of the support element on the traction means.
  • the support elements can then only be moved together due to a movement of the traction device along the bearing element and thus can not open unintentionally. If, on the other hand, the engagement means are released, the associated support element can be moved relative to the traction means and along the bearing element and thus adjusted, wherein the adjustment is possible independently of the other support element. Due to the fact that the supporting elements can only be moved together by the locking mechanism on the traction element when the traction element moves along the bearing element, it is a further advantage that the distance between the carrier elements remains constant during such a movement and therefore such an adjustment is also advantageous for an adjustment of the position of the recorded winding roll with respect to the desired web path in a machine can be used. Accordingly, the invention allows for structurally particularly simple, but at the same time effective way both the possibility of adjustment to different roll widths as well as the adjustment of the position of the recorded winding roll.
  • the invention essentially requires only simple and inexpensive mechanical elements. With the help of the invention can over conventional constructions Furthermore, a substantial cost reduction can be achieved, in particular in a basic version in which a manual operation is possible in a simple manner and is dispensed with any automation and the associated costly installation and maintenance of electronic components. Nevertheless, the construction according to the invention offers the advantage of upgrading to complete automation.
  • the currently most commonly required automation level is automatic side edge control, which adjusts the position of the already taken up take-up roll with respect to the web path; while the recording of the winding roll and the necessary adjustment of the distance of the support elements from each other takes place manually.
  • Such an automatic side edge control can be adapted with the invention with little effort, since only a single drive is needed.
  • the invention can be carried out preferably in two variants, in a first variant in which one of the two support elements provided with the rotatably mounted engagement means and the other support member is fixedly coupled to the traction means, and in an alternative second variant, at which on each of the support elements at least one rotatably mounted engagement means is provided.
  • the latter second variant allows more flexibility in setting to different roll widths. In principle, however, all adjustment options can also be realized with the first-mentioned variant.
  • a particularly preferred embodiment of the invention is characterized in that the engagement means is rotatably mounted about an axis of rotation, preferably approximately at right angles, to the direction of movement of the traction means and is engaged with the traction means such that the engagement means moves along the traction means during rotation moves and thereby a relative movement of the support element is given and locked at standstill, the support member on the traction means.
  • the rotatable mounting of the engagement means thus allows movement of the support member relative to the traction means, with the engagement means running along the traction means. If the engagement means by external action, be it manually or by a drive, set in rotation, this causes the engagement means repels the traction means and thus set the support member against the traction means in motion.
  • the distance of this support member relative to the other support member can be changed and adjusted to the width of the male winding roll in a simple manner.
  • the engagement means in the standstill this and thus the support member is locked to the traction means, which takes place in particular after receiving a winding roll.
  • the releasable locking is realized in that the rotatably mounted engagement means either on the one hand rotates freely or is driven in rotation and is held to the other for the lock at a standstill.
  • the traction means is designed as a flexible traction means, which circulates endlessly in a development of this embodiment.
  • the traction means not only structurally particularly simple form, but also arrange very compact.
  • the engagement means may be a roller and always a portion of the traction means are engaged with at least a portion of the circumference of the roller.
  • the role of the traction means can be wrapped in sections.
  • the traction means may be a rope or belt.
  • the traction means is a toothed belt and the engagement means is a gear or pinion whose teeth engage in the spaces between the teeth of the toothed belt.
  • the traction means is a chain and the engagement means is a gear or pinion whose teeth engage in the chain links of the chain.
  • the traction means should be at least partially movable along a substantially straight line. Since usually the two support members are provided for two-sided rotatable mounting a winding roll about its axis of rotation, should be directed approximately parallel to the axis of rotation about that substantially straight line along which the traction means is at least partially movable.
  • the drive device has at least one arranged on the bearing element drive for a driven movement of the traction means along the bearing element.
  • the drive device for a driven rotation of at least one engagement means comprise at least one arranged on the associated support member drive, which has a brake in a development of this embodiment to hold the engagement means when needed at a standstill.
  • electric motors are used as such drives.
  • the support members each have a bearing pin for rotatably supporting a winding roll, wherein the bearing pins are directed with their free ends facing each other and coaxial with each other.
