Definitions

  • the invention relates to a loom with a warp beam and a drive means, particularly a warp beam gear wheel for it, whereby the warp beam has a warp beam flange and a detachable connection is provided between the warp beam flange and the drive means.
  • Such looms having spur gear or wave gear clutches are known.
  • the clutches are disengaged mechanically or hydraulically.
  • solutions are known from EP 1 057 912 and DE 197 24 150 wherein the drive torque moment is transmitted through switchable spur geared clutches.
  • Both solutions have the disadvantages of a costly construction and a complicated operation. As a result the time needed for a warp beam exchange is prolonged. Further, there is the danger of a damage to the machine and to the product due to an improper operation.
  • the present applicant has realized already a space saving solution for looms by screwing the drive means, for example in the form of a gear wheel, directly to the warp beam shaft or to the warp beam tube and to remove the gear wheel with the warp beam from the loom with each warp beam exchange.
  • This makes the further transport of the warp beam more difficult.
  • the change of the warp beam gear wheel form the old to the new warp beam presents, in addition to extra work efforts, also a danger of injury to the worker when handling the loose, heavy warp beam gear wheel.
  • the object of the invention to provide a loom of the type described, which has a compact and rugged construction, which assures a highly loadable, durable and free of play transmission of the torque moment onto the warp beam and which makes possible a simple exchange of the large and heavy warp beam. Furthermore, the invention shall prevent damages to persons and equipment that could be caused by operating errors while exchanging the warp beam.
  • the drive means preferably a warp beam gear wheel, according to claims 1 and 5
  • the drive means is connectable with the warp beam by means of one or more screws, whereby the screws are operable through holes in the frame wall.
  • the term “holes” in this context is intended to include for example bores and openings of any shape and size and lateral notches in the frame wall.
  • the number and dimensions of the screws are so selected that a safe transmission free of play of the torque moment from the drive means to the warp beam flange is assured.
  • the operating of the screws through the holes in the frame wall makes possible a very close positioning of the drive means to the frame wall and thus a compact construction. On the one hand the compact method of construction saves construction space, while, on the other hand it increases the stability of the drive.
  • the screw tightening and screw loosening of the warp beam can be performed from the outer side of the frame wall, which is substantially simpler and safer than an operation on the inner side.
  • the drive means is mounted in a frame wall positioned on the drive side.
  • the warp beam can also be mounted through the drive means on its driven side in the frame wall as long as it is screw connected with the drive means.
  • the described close arrangement is an advantage for a stable, long life mounting of the drive means in the frame wall, because due to the close axial spacing between the drive means and the mounting position, the forces to be taken up by the bearing are also relatively small, particularly when the drive means is unscrewed from the warp beam.
  • the meshing of the gear wheels exists unchanged also during a warp beam exchange.
  • This feature permits close gear teeth tolerances and the gear teeth are subject to a small wear and tear. In turn, this feature also assures in this point a durable torque moment transmission substantially free of play. During the production no costly manufacturing measures are necessary, which would permit an axial displacement of the gear wheels relative to each other, while however minimizing play in the circumferential direction.
  • a support is arranged on the side of the warp beam at the drive means.
  • the support rotates with the drive means.
  • the support can for example be constructed as a pair of support bearings on which the warp beam supports itself during installation as well as during removal as long as it is not connected to the drive means.
  • This intermediate support makes easier, above all, during installation of the warp beam, the alignment of the threaded holes in the warp beam flange, with the holes in the drive means and thereafter the screwing-in of the screws.
  • an additional intermediate support structure for example in the form of a separate support frame, is no longer required.
  • Markings are advantageously provided on the drive means and on the drive facing side of the frame wall for a simple and safe operational sequence of the warp beam exchange. These markings indicate to the operator when the mentioned support assumes a warp beam holding position. In connection with support roller bearings this would be, for example, a lower position in which the warp beam rests on the support rollers. These markings may be visually seen or they may be electronic markings, for example, which are sensed by sensors that are connected, in a signal transmitting manner, with the loom control. The sensors signal to the loom control when the drive means stands in a position suitable for an installation of the warp beam or for removal of the warp beam. The control can generate for an operator a respective display for example on a display panel. A visible marking is advantageously so secured to the loom that it is clearly recognizable from different positions, when the drive means is in a position suitable for installing and for removing of the warp beam.
  • connection can be released and bolted only in one angular position, suitable for the warp beam exchange, of the drive element which is arranged about the common rotational axis.
  • the suitable angular position is in turn predetermined by the arrangement of the support.
  • a preferred possibility of this securing can be achieved by a hole pattern with an asymmetric arrangement of the through holes in the drive means, a respective arrangement of the holes in the frame wall and by a small spacing between the drive means and the frame wall.
  • the holes in the frame wall are for example through holes having a diameter insignificantly larger than that of the screw heads and if these through holes are arranged in the frame wall in accordance with the same hole pattern as the through holes in the drive means, then the screws can be screwed-in and -out only when the hole pattern in the drive means is in that angular position in which it is congruent with the hole pattern in the frame wall. In this angular position, the support stands in a warp beam holding position.
  • the asymmetric arrangement includes various kinds of asymmetries.
  • these are arrangements in which all the holes have the same spacing from the central axis but are arranged with different angles relative to each other.
  • these are holes which are arranged with different spacings from the central axis while having the same angular spacing from each other.
  • these are holes which are arranged with different spacings from the central rotational axis and with different angles from each other.
  • the described securing is advantageously realized in that the screwing-in and the screwing-out of the screw through the frame wall and through the closely spaced and arranged drive means, into and out of the warp beam flange is preferably possible only when the hole in the drive element s positioned exactly opposite to a respectively shaped hole in the frame wall.
  • a further preferred embodiment of the invention provides that more threaded holes are provided in the warp beam flange than holes arranged in the drive means.
  • One or more screws are preferably constructed as dowel screws for centering the warp beam relative to the common rotational axis.
  • the head of the at least one screw is smaller than the hole in the frame wall.
  • the drive means with the screws is arranged so close to the frame wall that each screw not screwed-in reaches necessarily with its head into the hole of the frame wall.
  • an energy storing means is operatively connected to and arranged with each screw, particularly a compression spring. The compression spring pushes the screw in a direction opposite to its screw-in direction into the holes of the frame wall.
  • the compression spring bears against a shoulder on the inner surface of the hole in the drive means.
  • the screw is secured by a securing element, for example a securing ring.
  • the securing element cooperates with a limit stop provided on the drive means, for example in the form of a fitting bushing arranged on the inner circumference of the respective hole in the drive means.
  • the securing element holds the at least one screw in a predetermined end position. In this way each not screwed-in screw is pressed against the limit stop by the energy storing means and held in this predetermined position.
  • Each screw is so dimensioned that it withstands the torque moment of a driving motor. That means, that a not screwed-in screw blocks the drive of the warp beam in that the screw bears against the inside of the respective hole in the frame wall.
  • a switch-off protector provided at the motor switches the motor off when blocking occurs. In this way damages to the loom and to the product are avoided. Such damages could otherwise occur during operation with not screwed-in screws and a warp beam only partially secured.
  • FIG. 1 shows a side view of the driven side of the warp beam
  • FIG. 2 shows a view of the driven side of the warp beam with the drive elements
  • FIG. 3 shows a sectional view of the drive elements of the warp beam according to section plane C-C in FIG. 1 ;
  • FIG. 4 shows an enlargement of a detail D in FIG. 3 .
  • FIG. 1 shows a side view of the driven side of the warp beam 2 with four screws 6 and four holes 4 . 1 in the frame wall 4 .
  • a loom 1 of the type described is provided with a warp beam 2 and a motor 7 for driving the warp beam.
  • the holes 4 . 1 and the screws 6 are arranged in accordance with an asymmetric hole pattern.
  • the heads of the screws 6 in the drive means 3 are visible through the holes 4 . 1 in the frame wall 4 .
  • In the shown angular position of the drive means 3 all screws 6 can be screwed-in and screwed out. This is not possible in any other angular position of the drive means 3 , because in that case not all or no screws 6 at all can be inserted and withdrawn through the holes 4 . 1 in the frame wall 4 .
  • the warp beam 2 comprises substantially a warp beam tube 2 . 1 , a warp beam flange 2 . 2 and warp beam discs 2 . 3 arranged on the warp beam tube.
  • the warp beam discs serve as lateral limits for the warp threads not shown.
  • FIG. 2 shows only the warp beam disk 2 . 3 on the driven side of the warp beam.
  • the warp beam flange 2 . 2 can be constructed as a one piece construction with the warp beam tube 2 . 1 or it can be a separately produced element rigidly connected to the warp beam tube. Separately produced warp beam flanges 2 . 2 make it possible to use differently formed warp beam tubes 2 . 1 whereby a warp beam flange 2 . 2 is adapted to the respective warp beam tube and can itself be used advantageously as an adapter element.
  • FIG. 2 further shows a motor 7 rigidly secured to a drive side frame wall 4 .
  • the motor drives a motor pinion not shown for driving a drive means 3 constructed as a gear wheel.
  • the drive means 3 is bolted to the warp beam flange 2 . 2 .
  • the warp beam flange 2 . 2 is, in turn, rigidly secured to the warp beam tube 2 . 1 .
  • FIG. 2 is equipped with a support 8 in the form of support bearings which are laterally secured to the drive means 3 .
  • a support 8 in the form of support bearings which are laterally secured to the drive means 3 .
  • the second support bearing is secured to the drive means 3 behind the visible support bearing and with the same spacing to the rotational axis 5 .
  • the two support bearings form together a rest for the warp beam flange 2 . 2 .
  • the support 8 holds the warp beam 2 in an installation position and in a removal position, however, while the warp beam is not bolted to the drive means 3 .
  • the temporary supporting of the warp beam 2 on support bearings 8 is, above all, advantageous during the installation of the warp beam 2 because the warp beam 2 can thus be rotated with a little energy input about its rotational axis into an angular position suitable for screwing-in the screws 6 .
  • FIG. 3 shows the assembled parts of the warp beam drive in a sectional view along the section plane C-C in FIG. 1 .
  • the drive means 3 is connected to the warp beam flange 2 . 2 by screws 6 .
  • the warp beam flange 2 . 2 is a separately produced element which is rigidly connected to the warp beam tube 2 . 1 .
  • the drive means 3 , the warp beam flange 2 . 2 and the warp beam tube 2 . 1 are thereby arranged around the common rotational axis 5 .
  • FIG. 3 also shows the closely spaced, space saving arrangement of the warp beam flange 2 . 2 , of the drive means 3 and of the frame wall 4 to one another. This arrangement is made possible first of all by the holes 4 . 1 in the frame wall for screwing-in and screwing-out the screws 6 .
  • FIG. 4 shows in an enlarged portion one of the screw connections between the drive means 3 and the warp beam flange 2 . 2 .
  • the screws 6 are operable through the holes 4 . 1 in the frame wall 4 and through the holes 3 . 1 in the drive means 3 for screwing into the warp beam flange 2 . 2 .
  • the warp beam 2 can be rigidly connected with the drive means 3 and separated from the drive means 3 .
  • each screw 6 is operatively connected to the drive means 3 by a compression spring 9 arranged on the circumference of the screw shaft.
  • the compression spring 9 bears against a shoulder 3 . 3 on the inner surface of the hole 3 . 1 and displaces the not screwed-in screw 6 opposite to the screw-in direction.
  • the screw 6 is secured by a securing ring 10 so that the compression spring 9 cannot push the screw 6 completely out of the hole 3 . 1 of the drive means 3 .
  • the securing ring 10 is arranged at the shaft circumference of the screw 6 and limits the displacement distance of the screw 6 by bearing against a fitting bushing 11 forming a stop.
  • the bushing 11 is pressed into the hole 3 . 1 of the drive means 3 .
  • This arrangement of the securing ring 10 and of the fitting bushing 11 also prevents that a screw 6 which is not screwed-in can fall out, for example due to vibrations.
