Definitions

  • the invention relates to a method and a device for aligning eyes of tableware elements for weaving machines.
  • Such devices and methods are primarily for the centering of the eyes of strands known in weaving machines be used.
  • the eye is then centered important if a thread is drawn through the eye should, because this is done, for example, by pulling devices, which at high speed is a pull-in needle Shoot through the eye with a warp thread. If there is one between the eye and the pull-in needle Touching it can damage the cord or the pulling process be disturbed.
  • the pull-in process but usually takes place outside the weaving machine.
  • the invention as characterized in the claims is, therefore, the task solves one method and one To create a device that allows the position of a Eye in a tableware element more precisely and at Correct need.
  • the sensor can act as a thorn be formed, which is movable across the eye on a sled is arranged, or as a light barrier that is transverse to Eye arranged and is formed switchable.
  • the sensor is also a switchable mechanical guide for the tableware element and a device for moving the tableware element assigned in its longitudinal direction.
  • Fig. 1 shows - in a view of an inventive Device according to a first embodiment, with mechanical Detection of the position of the eye - as a tableware element here a strand 1 partially cut and from the Seen from the side, with eyelets 2, 3 and one eye 4.
  • the strand is located in the retracted position in a retractor as is known for example from EP 0 500 848.
  • Two clamping devices 5, 6 and two clamping devices 7, 8 for moving the tableware element in its longitudinal direction are arranged along the strand 1, the clamping devices 5, 6 clamp or fasten the strand 1 after them by the clamping devices 7, 8, which in the eyelets 2, 3rd intervene, is positioned. All of the items listed above are known per se.
  • a Centering device 10 arranged with a sensor 11, the is attached to a carriage 12 which is inclined on a Level 13 is movably supported by a drive 14.
  • the sensor is designed as a mandrel and on a rocker 15 attached, which is rotatably mounted about an axis 16.
  • the Rocker 15 has a contact point 17 for a switch 18 on that is stored in a fixed position.
  • the clamping devices 5, 6 and the clamping device 8 have each have a drive 19, 20, 21 on the lines 22, 23, 24 are connected to a control unit 25. Also the Drive 14 is connected to control unit 25 via a line 26 connected.
  • Fig. 2 shows a top view of the rocker 15 as part of an inventive 1, with the Contact point 17, the sensor 11, which is shown here as a mandrel and a more visible side guide here 27, 28 for the strand. From the size relationships shown here shows that the strands in this case in the area of the eye should be very narrow.
  • FIG. 3 shows a view of a device according to the invention, according to a second embodiment, with optical Detection of the position of the eye.
  • sensors 30, 31 are included in themselves in a known manner from one source 37 and one Receiver 38.
  • a switchable mechanical lateral fork-like guide 32 is provided, since the sensor does not exert any forces on the strand 1.
  • FIG. 4 shows part of a device according to the invention, 3, with the guide 32 with the strand 1 and the beams of the light barriers 30, 31 in one view, which is rotated by 90 ° compared to the view in FIG. 3. It can be seen here that the guide 32 for much wider Eyes or braids. It is clear that the one shown Guide 32 also in the embodiment according to FIG. 1 mechanical scanning of the eye can be provided, and vice versa.
  • FIGS and 4 show two spatial views of an integral part 60, according to a preferred variant of a second Embodiment. While the sensors in FIGS and 4 are designed as light barriers Optical fibers 40, 41 selected (not shown). Like the sensors 30, 31 in the form shown in FIGS. 3 and 4, The first variant here is the sensors 40, 41 in two to each other parallel planes as shown of the bores 42 and 43, which these light guides 40, 41 record, is recognizable. These two light guides are available a common or two individual light sources 50 (not shown), in connection and direct it from this Light source or that emitted by these light sources Light on.
  • the light source 50 can be laser diodes, incandescent lamps and other light generating electrical components and doesn't necessarily need to be on the same level as the light guides to be arranged. While the light barriers 30, 31 preferably in two parallel to each other, inclined planes are arranged (Fig. 3) the light guides 40, 41 - at least in the direction defining the emitted light beam or light beam Area - in two horizontal, parallel to each other Levels.
  • the mode of operation of the invention is as follows:
  • the strands 1 or crockery elements are supplied on devices such as are known for example from EP 0 500 848. Such devices are, for example, part of a pull-in device and have holding means 34 which are arranged all around and bring the tableware element into a pull-in position in a manner known per se. This retraction position is also shown in FIGS. 1 and 3 for the strand 1. If the retracted position is reached, the strand 1 is tensioned by lifting the holding means 34 by the tensioning device 8 against the spring force of the tensioning device 7 and clamped by the clamping devices 5, 6, which is caused by the control unit 25, which causes the strand 1 to arrive suitable sensors have been reported.
  • the drive 14 is set in motion via the line 26, so that the slide 12 with the rocker 15, the guides 27, 28 and the mandrel or sensor 11 aligns the eye 4 from the outside and from the inside.
  • the sensor passes through the plane of the eye (here perpendicular to the plane of the drawing) and the mandrel 11 is finally located above the lower edge of the eye 4.
  • the control unit 25 outputs a signal via line 24 which controls the drive 21 in this way that the holding means 34 is shifted further upward in the longitudinal direction of the strand 1.
  • the lower edge of the eye 4 abuts the mandrel 11 and moves it upward, which is possible because of its or the mounting of the rocker 15 about the axis of rotation 16.
  • the contact point 17 moves away from the switch 18, so that the latter reports this to the control unit 25 via a line 35.
  • the upward movement of the strand 1 is limited by the tilted rocker 15. If the mandrel 11 does not hit the lower edge of the eye 4, there is also no corresponding signal, which means that the strand 1 is too worn out, that is to say damaged. However, if the signal described above is emitted by the switch 17, the clamping devices 5, 6 which have been loosened previously can be tightened again and the carriage 12 can be moved back by the drive 14. Then the eye is precisely aligned and the retraction process can be carried out. So far the centering of the eye 4 as it is carried out with the device according to FIG. 1.
  • the centering with the device according to FIG. 3 has several Steps up that are exactly the same as described above expire.
  • the difference is that with the Extending the guide 32 no mechanical sensor in the eye 4 is retracted.
  • the light barriers act as sensors 30, 31 switched on when extended, and the strand 1 centering outside, guide 32 across Illuminate eye 4 through.
  • the two light barriers 30, 31 check the position of the eye 4 in the vertical or longitudinal direction the strand 1. If both beams of the two light barriers 30, 31 present, i.e. are not interrupted so the position of the strand is good and the pulling-in process can kick off.
  • control unit 25 applies discrete signals are driven, which consist of that there is a signal or not, like this for the Switch 17 or light barriers 30, 31 applies.
