Definitions

  • the present invention relates to a traversing device for reciprocating a longitudinal thread over a stroke length with two debris of at least one endless belt running in opposite directions between the stroke reversing regions, the at least one belt being guided over deflection rollers to form the debris and the thread being passed through a driver on each belt can be moved back and forth alternately along a thread plane over a driver distance of the stroke length, and a drive device is provided for driving the at least one belt.
  • a known device of the type mentioned above (eg CA-PS 642'286) has drivers on the belt through which the thread is passed directly.
  • the belts or the axes of rotation of the deflection rollers of the same are arranged offset with respect to one another, as a result of which the thread in the stroke reversal area when transferred from the respective leading thread driver is released before it is taken over by the opposite thread driver.
  • the thread swings freely in the air, which is disadvantageous because, for example, its direction of movement is no longer secured.
  • Such a device requires an adjustment to the duration of the "standstill" of the thread at its stroke reversal point, so that a quick release and a quick take-up can take place by the opposite thread driver and thus the standstill time and thus an edge build-up is reduced to a minimum.
  • the thread impinges upon the take-over of the thread driver taking over, whereby the thread is locally impermissible and therefore undesirably stressed.
  • each belt has at least one driver and a thread guide is provided for the thread guided in the thread plane and can be moved along the same in at least one traversing direction by means of the at least one driver, and that a baffle is arranged as a catcher for the thread guide in each stroke reversing area, the thread guide being released by the driving driver in the stroke reversing areas and crashes into the baffle in free flight and changes its direction of travel and is only driven by the opposing driver after it has collided with the baffle.
  • the traversing device advantageously not only quickly reverses the thread guide and thus the thread, but also mechanically takes over the impact through the baffle and thus relieves the driver of the impact, with the thread at the points of reversal at the same time is led positively.
  • each belt can have at least one driver.
  • the thread guide can then be moved back and forth alternately by means of one or the other driver, wherein the thread guide can be transferred from the one driver to the other opposing driver in the stroke reversal areas.
  • the thread guide can also be drivable in both traversing directions by one and the same driver.
  • the thread guide is preferably guided in a guide parallel to the rubble.
  • the deflecting roller of the one belt that emits the thread guide can be arranged set back with respect to the respective baffle wall with respect to the deflecting roller of the other belt that takes over the thread guide.
  • the thread guide can have two guide surfaces for the driver and two impact surfaces with which it can impact the impact wall.
  • the stroke length preferably extends parallel to the axis of rotation of a bobbin receiving the thread if the traversing device is provided, for example for winding the thread.
  • the axes of rotation of the deflection rollers of the one belt are seen in relation to the deflection rollers in the lifting direction the other belt is preferably arranged offset, whereby the release of the runner from the driver can take place in an advantageous manner.
  • the deflection roller for the driver delivering the thread guide is preferably arranged within the distance between the two baffle walls.
  • an endless belt 1 is guided over the same radii r2 and r3 having pulleys 2 and 3, either the pulley 2 or the pulley 3 can be driven.
  • the belt 1 has a running direction A.
  • the deflection rollers 2 and 3 are located within a lifting range B, in which a thread 4 is to be moved back and forth, which runs along a thread plane E and is to be wound up (not shown).
  • Between the pulleys 2 and 3, ie in the stroke area B are Debris 5 and 6 of the belt 1.
  • a driver 7 fastened on the belt 1 engages on a guide surface 8 of a thread guide 10, which is located on a guide rail 11 which extends as far as the housing walls 12 and 13.
  • the guide surface 8 and a further guide surface 9 are formed on the thread guide by a recess 14 in the same.
  • the thread 4 runs through an eyelet 15 in the thread guide 10.
  • the deflection rollers 2 and 3 are arranged in respective stroke reversal areas E.
  • the thread guide 10 is driven by the driver 7 in the running direction A of the run 5.
  • the driver 7 is deflected by the belt running over the deflection roller 2 and releases the thread guide 10, which hits the housing wall 12 in free flight as a baffle.
  • the thread guide 10 changes its traversing direction and, after its impact on the baffle 12, returns to the area of the driver 7, which now begins its movement on the run 6 when it rotates around the deflection roller 2 .
  • the driver 7 can engage the guide surface 9 of the thread guide 10 and drive it in the direction of arrow F.
  • the impact plane D is present on the housing wall 13 and is also reached there when it is reached of the stroke reversal area E there is a free flight of the thread guide 10 after release by the driver 7, an impact of the thread guide on the baffle 13 and a re-engagement of the driver 7 in the guide surface 8.
  • the thread guide 10 and thus the thread 4 are shifted over the stroke range B in constant change
  • the baffle 12 with the impact plane D is arranged at a distance G from the center plane H of the deflection roller 2, at which the driver 7 takes over the thread guide 10, that is to say the receiving deflection roller, when viewed in the direction of travel F. It is assumed that the driver 7 leaves the thread guide 10 at point P1 and e.g. takes over at a point between the points P2 and P3 or at the point P3 on its route around the pulley 2.
  • the distance G is e.g. depending on the distance K of the driver 7 from the center plane H in its takeover position between the points P2 and P3 for the thread guide 10th
  • the belt idlers 23 and 27 can be driven by a drive roller 28 and 29, respectively.
  • the drive roller 28 rotating in the direction of arrow L drives the belt 20 in such a way that a run 30 thereof runs in the direction of arrow M.
  • the drive roller 29 rotating in the direction of arrow N drives the belt in such a way that a strand 31 thereof has a running direction P which is opposite to the running direction M.
  • the debris 30 and 31 face each other.
  • the driver 7 which in turn can engage guide surfaces (not shown) of a thread guide 32 and can move it back and forth in the running direction M or P over the stroke range E.
  • the thread guide 32 is in turn seated on a running rail 33 which is located between baffle walls 34 and 35.
  • the thread 4 in turn runs through an eyelet 36 of the thread guide 32, which thread is moved through the stroke range E by the back and forth movement of the thread guide.
  • the baffle 34 is again arranged with an impact plane Q at a distance G from the center plane H of the deflection roller 25, which takes over the thread guide, in which the parameter already described above can be included.
  • the distance of the baffle 35 from the center plane of the guide roller 22 can be be true.
  • the deflection roller 21 around which the driver 7 runs when the thread guide 32 is released i.e. the deflecting roller 21 emitting the thread guide 32 is arranged with its center plane R at a distance S from the center plane Z of the accepting deflecting roller 25.
  • This distance S is e.g. depending on the path diameter U of the circumferential path of the driver 7 around the receiving deflection roller 25 and the distance K of the takeover position of the driver 7 from the center plane H of the receiving deflection roller 25.
  • a belt 40 can be guided over two deflection rollers 41 and 42 and driven by means of a drive roller 43, so that a run 44 receives the running direction T.
  • Another belt 45 is arranged with its run 46 opposite and parallel to the run 44 of the belt 40.
  • the belt 45 is guided over deflection rollers 47 and 48 and driven by a drive roller 49, so that its run 46 receives a running direction U which is opposite to the running direction T of the run 44.
  • the deflection rollers 41, 42 and 47, 48 are in turn located between two housing walls 50 and 51, between which a guide rail 52 for a thread guide 53 extends, the deflection rollers 41 and 47, or 42 and 48, with their axes of rotation DA in each case a level V face each other.
  • the thread guide 53 is opened by a driver 54 the belt 40 and a driver 55 on the belt 45 as in the embodiments described above in a stroke reversal area between the housing walls 50 and 51 to and fro. In this way, a thread (not shown) guided through an eyelet 56 of the thread guide 53 can be moved over the stroke range.
  • the thread guide 53 is released by the respective driver 55 in the stroke reversal area and can impact in free flight against the baffle walls formed by the housing walls 50 and 51.
