Definitions

  • the present invention relates to a holder for a device for optical quality monitoring of a woven web on a weaving machine, comprising a holder, the monitoring device extending over the entire width of the woven web according to the preamble of patent claim 1.
  • Devices of this type are known, for example, from US Pat. No. 4,728,800, WO 95/16909, CH-675,306 or in particular also from EP-A-1,249,530.
  • Such devices are used in particular for optical quality monitoring of a textile web directly on the weaving machine.
  • Such errors can be, for example, broken threads in the warp or weft threads, stains or other optical errors that deviate from the normal weave image.
  • the captured images must be as possible high contrast and sharp. Achieving a high-contrast and sharp image requires optical scanning as close as possible to the web. Accordingly, such devices are held directly on the loom and in contact with the woven fabric.
  • JP-A-09 '78' 444 shows a web inspection device according to the preamble of claim 1, which is held in contact with the woven web in the area between a take-off roller and the winding of the web.
  • JP-A-09 '78' 444 shows a web inspection device according to the preamble of claim 1, which is held in contact with the woven web in the area between a take-off roller and the winding of the web.
  • Attaching the monitoring device in the area between the take-off roller and the winding of the web onto a goods tree or on a large dock is particularly useful here.
  • this area In this area there is usually a deflecting or spreading roller, which smoothes the woven material web before winding it up.
  • This area is relatively distant from the point of production of the woven textile web. Vibrations and Vibrations of the textile web itself are less here. Since the web is also brought into contact with the monitoring device, the relative movements are reduced with the exception of the feed of the web. Due to the indirect mounting of the monitoring device according to the invention via two pivot axes, the vibrations are also transmitted indirectly and thus in a reduced manner. By means of these deflection points, the vibrations are no longer transmitted directly and, in addition, the bearing of the monitoring device on the woven material web can be precisely adjusted and, moreover, it can be pivoted away for maintenance work without having to dismantle the inspection device.
  • FIG. 1 shows a perspective partial view of a weaving machine on which a monitoring device is held by means of the holder according to the invention.
  • FIG. 2 again shows a perspective view of another weaving machine with an alternative arrangement of the monitoring device
  • Figure 3 shows a constructive alternative to a mounting of the monitoring device on a loom.
  • FIG. 4 serves to explain the preferred mounting position of the monitoring device.
  • FIG. 1 and 2 each show a weaving machine 1 in a perspective partial view.
  • the textile fabric web produced thereon is designated by 2.
  • An optical monitoring device 3 is arranged on the weaving machine 1 in order to determine any defects on the web 2 that occur during production.
  • This monitoring device which stretches across the entire width of the web 2, scans the textile web, for example by means of scanners or other optical sensors. In order to obtain a picture that is as flawless as possible and thus a correctly functioning quality monitoring, it is essential where such a monitoring device 3 is arranged on the weaving machine 1.
  • the monitoring device 3 is arranged relatively shortly before the winding of the web 2 on a goods tree 10, namely in the area 6 between a take-off roller and the winding on the goods tree or the large dock , A spreading or deflection roller located here is smoothed the textile web before winding.
  • the Warrenbah ⁇ 2 also has a desired tension.
  • the optical monitoring device 3 lies directly on the web 2.
  • the wall of the monitoring device 3 facing the material web has corresponding windows, behind which optical sensors, for example scanners, are arranged and protected by a transparent layer.
  • FIG. 4 shows a schematic partial section through a weaving machine. After the actual weaving point, the finished textile web is conveyed by means of a mostly driven take-off roller 30.
  • the material web 2 is applied to the take-off roller 30 via a breast boom 31 and then via one or more deflection rollers 32 in.
  • FIG. 2 shows an alternative in which, on another weaving machine 1, the monitoring device 3 is arranged in front of the spreading roller or deflection roller 33, viewed in the transport direction of the textile web 2.
  • the monitoring device 3 is arranged in the area of the take-off roller and the goods tree 10, or the large dock. It is preferred to mount the monitoring device 3 in the vicinity of the spreading roller 33 or the deflection roller 32 arranged here instead, provided that these are present on the weaving machine.
  • the spreading roller 33 is mentioned, a deflecting roller which is instead present in this area should also be meant.
  • the term proximity should be understood to mean that between the point of contact of the optical monitoring device and the . Touch location of the 'no further spreading roller or rollers webmaschineneigene Run the bars in contact with the textile web 2.
  • the mounting of the monitoring device 3 according to the invention is designated 5 overall. It comprises an axis 7, which is arranged on the monitoring device 3, and a second, parallel axis 8, which is arranged on the weaving machine 1.
  • the axis 7 on the monitoring device 3 is usually formed by two retaining bolts 13. These two retaining bolts 13 lie on a straight line which represents the axis 7.
  • the axis 8, which is mounted on the weaving machine 1, can be a crossbeam which is already present on the weaving machine or a piece of pipe which is fastened to the machine by means of a base 18.
  • the holder 5 has a sleeve 12, which is formed from two half-shells 11 and can be clamped on the axis 8 in a stable position.
  • the design with two half-shells 11 also allows installation on continuous axes of different diameters already present on the machine.
  • One of the two half-shells 11 is connected in one piece to the swivel arm 9.
  • the axis 7 of the monitoring device 3 is supported in this swivel arm 9, which in this embodiment has a bearing housing 14.
  • the bearing housing 14 essentially consists of a cheek in which the axis 7 of the monitoring device 3 'is pivotally mounted.
  • a clamping bolt 15 which passes through the housing 14 rests in an arcuate elongated hole 16, by means of which the monitoring device can be locked in a certain angular range relative to the web 2 so that it can be pivoted about the axis 7.
  • the holder 5 over two axes 7, 8 gives the monitoring device 3 great freedom of adjustment relative to the web 2.
  • the monitoring device directly on the weaving machine 1 with bases. This would , however, transmit the vibrations of the weaving machine directly to the monitoring device 3, as a result of which the optical image would be deteriorated.
  • the vibrations are transmitted less directly and the vibrations still occurring are additionally insulated by the textile web on which the monitoring device 3 rests.
  • the holder according to the invention consequently not only realizes an optimized arrangement with great freedom of adjustment of the monitoring device relative to the textile web 2, but also improves the optical result at the same time, since vibrations are transmitted less directly.
  • the bearings can of course also be provided with corresponding bearing materials, which additionally lead to vibration absorption.
  • FIG. 5 An alternative form of the holder 5 is shown schematically in FIG.
  • the monitoring device 3 is located
  • the swivel arm 9 consists essentially of a double-sided clamping bracket.
  • the swivel arm 9 is made from a rod. This rod has two bearing bores 19, each of which is penetrated diametrically by a longitudinal slot 20.
  • the swivel arm 9 can be locked on the one hand in an adjustable angular position with respect to the weaving machine 1 and on the other hand in an adjustable angular position with respect to the monitoring device 3. Accordingly, the monitoring device 3 can in turn be pivoted more or less towards the textile web 2 and, on the other hand, the monitoring device can be arranged at a relative angle to the web 2. Both directions of movement are of eminent importance for optimal optical scanning of the web 2.
