Definitions

  • the invention relates to a traversing device according to the preamble of patent claim 1.
  • two endless belts each rotating over two idler rollers, are arranged in such a way that one strand of one belt is guided parallel to one strand of the other belt at a short distance.
  • the guide rollers of one belt and the guide rollers of the other belt are arranged coaxially or with offset parallel axes next to one another, that is to say in such a way that the guide roller of one belt and the corresponding guide roller of the other belt face one another on one side.
  • a single circumferential belt is present. This forms the one, longer strand between two outer guide rollers and the other, shorter strand of the traversing area between inner guide rollers. All the guide rollers lie in one plane and, if you look in the direction of movement of one of the dreams, in a row one after the other.
  • the outer guide rollers are arranged at a relatively large distance from one another. In the space between the two outer idlers - closely adjacent - an inner idler is assigned.
  • the inner guide rollers guide the shorter strand on a distance that corresponds approximately to the center distance of the two inner guide rollers and defines the maximum possible traverse stroke, at a short distance parallel to the oncoming longer strand.
  • the course of the belt is approximately S-shaped, so that the belt rests with one side surface on the outer and with the other side surface on the inner idler. The drivers sit on a narrow edge of the belt.
  • DE-OS 36 27 544 also describes a belt changer with a single belt which is guided over outer and inner guide rollers. These are arranged similarly to the device described above, but the belt between the outer guide roller and the associated inner guide roller is guided in the form of a reversing loop via an additional deflection roller. All roller axes are parallel, so that the belt - as in the device described above - runs in one plane. This plane is parallel to the plane of the traversing triangle.
  • a device which is described in US Pat. No. 3,333,782 differs from this, inter alia in that the axes of the different rollers are slightly inclined to one another.
  • the two strands of the traversing area are not exactly parallel, but intersect at a very acute angle. This is to facilitate the transfer of the thread at the end of the traversing area.
  • this arrangement does not change the fact that in this device, too, the four guide rollers, viewed in the direction of movement of one of the strands, are essentially arranged in a row one behind the other.
  • the belt is upright in relation to the level of the traversing triangle and the drivers sit on a narrow edge of the belt.
  • the belt rests with one side surface on the outer, with the other side surface on the associated inner guide roller.
  • the traversing stroke i.e. the spool length
  • the traversing stroke can obviously not be greater than the distance on which the two strands run parallel or almost parallel to one another. This distance is equal to the center distance of the two inner idlers, i.e. the shorter run defines the traversing stroke.
  • the roll diameter cannot be chosen arbitrarily small.
  • the minimum permitted roller diameter depends on the type of belt and is specified by the belt manufacturer.
  • the belt changers belonging to the state of the art have considerably longer lengths and the resulting coil spacings than with changers, which are equipped, for example, with reverse thread shafts.
  • DE-OS 37 39 850 deals with the last discussed problem and describes a traversing device in which at the two ends of the traversing area two guide rollers with parallel axes in a plane are arranged mirror-symmetrically next to one another, so that the two dreams passing through the traversing area are the same are long.
  • Each of the two idler rollers is assigned a laterally arranged deflection roller.
  • the belt is looped around both guide rollers and the part of the belt connecting the two guide rollers is guided at a short distance from or behind the two guide rollers.
  • the entire rotation of the belt lies on one level.
  • the overall length / traversing stroke ratio is considerably more favorable than with the other belt systems.
  • it has the disadvantage that it is very bulky in the direction transverse to the traversing movement in a plane parallel to the traversing triangle. As a result, their possible uses are limited, and the fundamentally existing advantage cannot always be fully exploited for design reasons.
  • Japanese Laid-Open Specification 51-96 546 also discloses a belt traversing device of the type mentioned at the outset, with two strands which are moved in opposite directions in the traversing region and each end is guided by guide rollers.
  • the strands are connected via deflection rollers arranged within the traversing area in such a way that the belt is twisted in the area of the reversing loops of the strands in each case in the manner of a spatial gear.
  • the invention has for its object to provide a traversing device of the type specified in the preamble of claim 1, which is a very compact unit both in terms of width and depth.
  • the belt lies on all the rollers over which it is guided with the toothed inside. There is no counter-curvature at any point in the cycle.
  • the drivers sit on the outer surfaces of the belt.
  • the belt strands pass through the traversing area in a flat position, that is to say the outer surface is at least approximately parallel to the plane of the traversing triangle.
  • the arrangement specified in claim 2 has advantages in operation because the lines on which the drivers move in the traversing area lie close together.
  • the combination of features of claim 3 is particularly suitable for ensuring an exact thread transfer at the reversal points of the traversing area.
  • the indication contained in claim 1 that the guide rollers are arranged "side by side” does not exclude that they are offset according to claim 3, for example by a piece which corresponds approximately to the radius of the guide roller.
  • the formation of the driver according to claim 4 has the advantage that the driver - compared to the double wedge-like used mostly in other belt systems Carriers - practically cause no local stiffening of the belt and have only a very small mass, this improves the smoothness.
  • FIG. 1 and 2 show two views of an embodiment from two mutually perpendicular directions.
  • 3 and 4 show schematic views according to arrows VII and VIII of FIG. 1.
  • each guide roller 24 to 27 is mounted on its own axis.
  • the axes of the guide roller pairs 24, 25 and 26, 27 are inclined and intersect at an obtuse angle in the projection according to FIGS. 3 and 4.
  • the axes of the two guide rollers 24, 25 as well as the axes of the two guide rollers 26, 27 in the direction in which the strands 35, 36 extend are offset from one another by a distance which corresponds approximately to the radius of a guide roller.
  • the axes and the holding members of the guide rollers 24 to 27 have not been shown in FIGS. 1 to 4; for example, they can be attached to the base plate 23.
  • the guide rollers 24, 25 as well as the guide rollers 26, 27 are arranged next to one another and face one another on one side.
  • the toothed belt 33 wraps around the guide rollers 24 to 27 each in an angular range of 180 °.
  • the drivers 34 are designed as thin pins and protrude obliquely from the outer surface of the belt 33, so that they are aligned perpendicular to the plane of the traversing triangle as they pass through the traversing area, as can be seen from FIGS. 3 and 4.
  • the geometric axes of the deflection rollers 28, 29 are arranged at right angles to the direction in which the strands 35, 36 extend and, in the representations according to FIGS. 3 and 4, coincide with the bisector of the obtuse angle that the axes of the guide rollers have Include 24, 25 and 26, 27, respectively.
  • the reversing loops 37, 38 overlap in such a way that the deflecting roller 28 belonging to the reversing loop 37 of the pair of idler rollers 24, 25 is closer to the other pair of idler rollers 26, 27 than the deflecting roller 29 belonging to the reversing loop 38 thereof.
  • the idler rollers 26 , 27 a slightly smaller diameter than the guide rollers 24, 25, so that the two reversing loops 37, 38 lie in separate planes. These two levels are parallel to the level in which the two dreams 35, 36 run.
  • the deflection roller 29 sits on the shaft 31 of a drive motor 32.
