  • Kettbaumwelle and Kettbaumtechnikrad braced against each other, but this solution has the disadvantage of a complex construction. Another disadvantage arises from the axial displacement of the warp beam in relation to the driving pinion at each disconnection of the drive connection. This sliding connection between the drive pinion and Kettbaumtechnikrad requires a certain initial game in the

  • the drive means e.g. screw in the form of a gear directly on the Kettbaumwelle or Kettbaumrohr and remove the gear at each Kettbaumcic with the warp beam from the loom.
  • this complicates the further transport of the warp beam.
  • the change of Kettbaumtechnikrades from the old to the new warp beam is in addition to the additional work and a further risk of injury to the operator when handling the loose, heavy Kettbaumtechnikrad.
  • the invention is therefore an object of the invention to provide a loom of the type described, which has a compact, sturdy construction, a highly resilient and permanently play-free transmission of torque on the warp tree ensures and allows easy change of the large and heavy warp beam. Furthermore, the invention is intended to prevent personal injury and property damage as a result of operating errors during the warp beam change.
  • the drive means preferably a warp gear, according to claims 1 and 5 by means of one or more screws connected to the warp beam, wherein the screws are to be operated through recesses in the frame wall. Holes and openings of any shape and size as well as lateral cuts in the frame wall are understood here as recesses.
  • the screws are designed in number and dimensions so that a safe and backlash-free transmission of torque from the drive means is ensured on the Kettbaumflansch.
  • the operation of the screws through the recesses in the frame wall allows a very close arrangement of the drive means to the frame wall and thus a compact design.
  • the compact design saves to a space and on the other hand increases the stability of the drive. In particular, in high-speed looms so that the tendency to vibrate is advantageously minimized.
  • the fixing and unscrewing of the warp beam can be done from the outside of the frame wall, which is much easier and safer than an operation from the inside.
  • the drive means is mounted in a drive-side frame wall.
  • About the drive means and the warp beam can be stored on the drive side in the frame wall, as long as it is bolted to the drive means.
  • the described close arrangement is advantageous because with a small axial distance between the drive means and the bearing and the forces to be absorbed by the bearing are relatively low, especially if the drive means is unscrewed from the warp beam ,
  • the drive-side engagement of the gears remains unchanged even when Kettbaum lymphosar.
  • This allows close tolerances in the teeth, and the teeth are subject to low wear, which in turn ensures a permanent almost backlash-free transmission of torque even at this point.
  • no complex manufacturing measures are necessary, which allow axial displacement of the gears against each other, but minimize the game in the circumferential direction.
  • this is accommodated in an eccentrically arranged bore in the drive means, wherein the Kettbaumflansch is centered and fixed by at least one further, with the Kettbaumflansch and the drive means operatively connected element in the common axis of rotation.
  • This element is e.g. a passport or a dowel pin.
  • a support kettbaum mass on the drive means with this mitbedorfd arranged.
  • the support may for example be designed as a pair of support bearings on which the warp beam is supported both during installation and removal, as long as it is not connected to the drive means.
  • This intermediate storage facilitates, especially when installing the warp beam, the alignment of the threaded holes in the Kettbaumflansch on the holes in the drive means and then screwing the screws. Despite the high weight of the warp beam can be this rotate on rotatable support bearings with little effort. An additional intermediate storage device, for example in the form of a separate storage rack is thus no longer required.
  • the markers may be both visually detectable markers and electronic markers which may be e.g. be detected by signals transmitted to a controller of the loom connected sensors.
  • the sensors signal the controller when the drive means is in a suitable position for installation and removal of the warp beam.
  • the controller may then provide the operator with e.g. Generate a corresponding display on a control panel.
  • a mark to be visually detected is advantageously attached to the loom so that it is clearly recognizable from various positions when the drive means is in a suitable position for installation and removal of the warp beam.
  • connection can be released and screwed only in an angular position of the drive element arranged around the common axis of rotation for the warp beam change.
  • the appropriate angular position is again given by the arrangement of the support.
  • a preferred possibility of this protection can be achieved by a drilling pattern with an asymmetrical arrangement of the through holes in the drive means, a corresponding arrangement of the recesses in the frame wall and by a small distance between the drive means and the frame wall.
  • the recesses in the frame wall are designed, for example, as through holes which have only a slightly larger diameter than the screw heads, and if these through holes are arranged in the frame wall according to the same hole pattern as the holes in the drive means, the screws can only be screwed in and out when the drilling pattern in the drive means is in the angular position in which it is congruent with the drilling pattern in the frame wall. In this angular position, the support is in a position holding the warp beam.
  • asymmetrical arrangement various types of asymmetry are understood here.
  • holes that are arranged at different distances from the central axis of rotation and at different angles to each other are understood here.
  • the described protection is advantageously realized by the screwing and unscrewing of the screw through the frame wall and the closely arranged drive means in and out of the Kettbaumflansch is preferably only possible if the Hole in the drive element is exactly opposite a correspondingly shaped recess in the frame wall.
  • a further preferred embodiment of the invention provides that in the Kettbaumflansch more threaded holes are arranged as holes in the drive means.
  • one or more screws are preferably designed as fitting screws.
  • the head of the at least one screw is smaller than the recess in the frame wall.
  • the drive means with the screws is arranged so close to the frame wall, that any screw not screwed with its screw head forcibly into the recess of the frame wall protrudes.
  • any screw not screwed far enough protrudes into the corresponding recess to block any further rotational movement of the drive means in each case is on each screw operatively connected to the screw energy storage means, in particular a compression spring arranged.

  • the compression spring is supported on a shoulder on the inner surface of the bore in the drive means.
  • a securing element for example a securing ring.
  • the securing element cooperates with an end limit provided on the drive means, for example a fitting bush arranged on the inner circumference of the respective bore in the drive means, and holds the at least one screw in a predetermined end position. Each unscrewed screw is thus pressed by the energy-storing means against the end limit and held in this predetermined position.
