Definitions

  • the invention relates to a method and a device for scanning the edge of the goods in a weaving machine and a weaving machine with such a device.
  • DE-A-3 435 391 discloses that the edge positioning of a video camera is captured.
  • another method which is based on the preamble of claim 1, e.g. a feeler shifted in the warp direction and the Edge of goods determined by an output signal, when the sensor has passed the edge of the goods.
  • This method has the disadvantage that the scanning too a predetermined point in time and that Assumption that the movement of the goods edge is completed is.
  • the invention has for its object a method to improve the scanning of the edge of the goods, in which the goods edge movement during the standstill of Loom is scanned.
  • This method is advantageous all movements of the goods edge during the Downtime of the weaving machine e.g. at Bug fixes found.
  • the reset of the The edge of the goods can be done immediately and then the Loom to be started.
  • the probe is advantageously in the bottom of the Fabric web introduced because this places the Probe organ inside the tissue web and with one minimal distance from the edge of the goods is made possible.
  • An apparatus for performing the method is according to the invention by the features of claim 5 featured.
  • a housing 1 In a housing 1 are a stylus 2, an electromagnet 3, an inductive Displacement sensor 4, a one-armed lever 5 and a tension spring 6 arranged.
  • the electromagnet 3 has an armature part 7.
  • the Lever 5 is hinged at one end to a housing wall 8 and lies on the anchor part 7.
  • the stylus 2 is on attached at one end to the lever 5 and is in one Elongated hole 9 guided in a second housing wall 10.
  • Position sensor 4 interacts.
  • a stylus 23 In a housing 21 are a stylus 23 a two-way air cylinder 23rd and a contact arrangement 24 are arranged.
  • the impression cylinder 23 has a piston 25 and is via two hose lines 26 with a compressed air source, not shown connected.
  • the stylus 23 is at one end with the Piston 25 connected and at the other end in an elongated hole 26 guided in a housing wall 27.
  • the contact arrangement has two contacts, the contact surfaces of which are at a distance are arranged to each other.
  • the stylus 22 is between the contact surfaces, the distances between the stylus and the contact surfaces are the same.
  • the weaving process may be due to operational problems in the Weaving machine or defects in the threads to be woven to be interrupted.
  • the lever 5 is pivoted and the needle in the Fabric web 18 driven.
  • the Elongated side surfaces a guide that a lateral Deflection of the stylus restricted.
  • the position of the in the stylus inserted with respect to the Position sensor is in the zero position Machine control saved.
  • Interruption of operation of the weaving machine becomes the position of the Due to different causes and Operations e.g. by automatically relaxing the tissue and the warp threads changed.
  • the device is in a weaving machine on the Weaver stand in front of reed 17 and below Fabric web 18 arranged so that the stylus 2, 22 is close the goods edge 19 can be inserted into the fabric web 18 (Fig. 1).
  • a particular advantage of the device described is also that when used with Air looms, as is known during the Weft thread stop, the edge of the goods from the weft insertion channel is covered, can be used unhindered.
  • the stylus 2 is one Actuator 3 connected to the stylus 2 in insert the fabric web 18 and with a displacement sensor 3 inductively coupled to the displacement of the goods edge 19th to eat.
