Definitions

  • the invention relates to a weft stretching and detection device for Jet looms, the device on the exit side of the weft insertion channel a reed is arranged and together with the reed on the leaf bar of the Loom is mounted.
  • EP 0 716 171 A2 discloses a weft stretching and detection device for jet looms in which the weft stretching takes place in a technical unit and in which any long weft or weft breakage is detected and the signal generated is transmitted to a weaving machine control system in a signal-transmitting manner.
  • the weft thread to be stretched by means of a flowing medium is directed from the weft thread insertion level, which forms the first arrangement level for a weft thread guide channel in the known device, into a weft thread guide channel lying in a second arrangement level, which corresponds to the stretching of the weft thread.
  • the weft thread stretching is deactivated, the weft thread is inserted into a weft thread guide channel present in the device downstream of the weft thread insertion channel and, if necessary, stretched by the air flow of an existing nozzle device without deflecting the weft thread.
  • the known device has the disadvantage that each arrangement level in each case requires a weft monitor and that because of the less favorable air flow conditions in comparison to the weft insertion channel of the reed an additional nozzle device (not shown) for stretching the weft thread is necessary in the first arrangement plane of the weft thread guide channel.
  • the object of the invention is to provide a device for optionally redirecting stretching Detecting the weft thread incorrectly entered in the shed of a weaving machine create one over the device known from the prior art has a simpler structure, achieves greater functional reliability and is easier to handle is.
  • the weft stretching and detection device consists of a first technical unit, which is the deflecting stretching of the weft thread causes, and consists of a second technical unit that is relative to the first technical Unit on the sheet bar of the weaving machine together with a single one Weft monitor is slidably arranged, the weft monitor arriving of an incorrect weft thread and a corresponding electrical signal Loom control unit, not shown.
  • the advantage is that the device only requires a weft monitor that the Set up on the middle section of that existing in the first arrangement level Thread guide channel of the known device is dispensed with, as a result of which the invention Furnishing is lower in mass, and that ultimately with just a single adjustment second technical unit, which has a single weft monitor, the The stretching behavior of the weft threads can be adjusted relatively quickly. It should also be mentioned that in the context of functional tests of the invention trained facility was recognized that with the waiver of the middle section none of the thread guide channel extending in the first arrangement level Impairment of the weft flight goes hand in hand. Rather, the size of the energy accelerating the weft thread is still sufficient to in the event of a weft break, the torn weft length in the first or to detect the second arrangement level of the second technical unit.
  • the input is in the first Arrangement level lying weft guide channel biconical. So that will ensures that the weft in question is unimpeded in the
  • the second technical unit can enter the weft guide channel.
  • the weft stretching and detecting device does not consist, as is known from the prior art, of a unit in a common unit connected to the sheet bar of the weaving machine with integrated devices for stretching and detecting a weft thread, but according to the invention consists of one first separate technical unit 1a with means 4, 5, 5a and 6, 6a, 6b for stretching a weft 11 correctly inserted into the weft insertion channel 2a of a reed 2 and from a second separate technical unit 1b with means 10 for guiding and detecting an incorrectly in the weft insertion channel 2a of the reed 2 inserted weft 11, both technical units being arranged downstream of the weft insertion channel and the second technical unit 1b being adjustable on the sheet bar 3 relative to the first technical unit 1a.
  • the weft stretching and detection device 1 can dispense with thread guidance in the first arrangement level between the first technical unit 1a, that is to say the weft stretching device, and the second technical unit, that is to say the weft thread detection device.
  • the thread guide 9 lying between the technical unit 1a and the technical unit 1b can, as is known per se, be designed as a telescopic tube. If a thread guide is dispensed with in the first arrangement level between the first technical unit 1a and the second technical unit 1b, the input 7a of the thread guide 7 is biconical in a further embodiment of the invention.
  • the only weft monitor 10 monitoring both arrangement levels in the technical unit 1b can be a generally known weft monitor, so that there is no need to go into this in greater detail.
  • FIG. 2 the separate one held in the sheet bar 3 by means of a clamping piece 3a technical unit 1a with the integrated weft stretching device 5, 5a, 6, 6a shown.
  • the second technical unit 1b which is adjustable relative to the first technical unit 1a, is shown in FIG.
  • the technical unit 1b is connected to the sheet bar 3 in the same way as the technical unit 1a.
  • the biconical design of the entrance 7a of the thread guide 7 is clearly visible here.
  • the relative adjustability of the technical unit 1b is indicated in FIG. 1 by means of the double arrow 12.
