Definitions

  • the invention relates to a thread conveying device for a weaving machine according to the preamble of claim 1.
  • Thread conveyors for a weaving machine are in large numbers, e.g. known from DE 3408515C and WO 97/00342.
  • the conveyor surfaces are designed as conveyor belts or conveyor drums.
  • the conveyor drums can have a continuous cylinder surface or can be formed from rods which are arranged parallel to the circumference of the drum axis.
  • Such thread conveyors are known for constant delivery quantities as well as for adjustable ones. It is disadvantageous that the thread to be conveyed always interacts with the conveying surface at the same point. In the course of operation, this leads to the thread being cut or buried into the conveying surface, as a result of which faultless thread conveying is no longer guaranteed, in particular if the thread is held on the conveying surface with pressing means and / or is under tension.
  • DE-C-527468 discloses a thread layer designed as a grooved drum for a winding machine, in particular a cross-winding machine.
  • This grooved drum is used for the positioned winding of a thread on a spool core and gives no suggestions for its use for guiding a thread in the thread conveying device of a weaving machine.
  • the object of the invention is to improve a thread conveyor device of the type mentioned.
  • the conveying surface is assigned a grooved drum which leads the thread back and forth transversely to the conveying direction with a helical groove loop which leads the thread back and forth transversely to the conveying device, it is prevented that the thread always lies in the same place on the conveying surface, but instead moves back and forth across the conveying direction.
  • Digging in and thus running-in marks of the thread in the conveying surface are prevented or, in the worst case, only occur after a considerably longer operating time. This results in a thread conveying device which ensures a faultless delivery of the thread over a long period of operation, thereby avoiding errors in weaving and in the fabric.
  • the grooved drum can have its own drive, which enables the speed of the grooved drum to be set individually.
  • An embodiment according to claim 3 is particularly simple, according to which the grooved drum the conveying surface rests and can be driven by the latter by means of frictional engagement.
  • the embodiment according to claim 4, which has an extremely simple structure, is particularly preferred. Care will preferably be taken to ensure that the circumference of the grooved drum is not an integral multiple of the length of the conveying surface, so that the thread comes into engagement with the conveying surface at constantly changing areas in order to further prevent the thread from running into the conveying surface.
  • the conveying surface can be configured according to claim 7 as a conveyor belt or according to claim 8 as a conveyor drum.
  • the thread conveying device can be used to supply an auxiliary thread, a catching thread or, in particular, a weft thread on a weaving machine, in particular a needle-weaving machine.
  • Figure 1 shows a thread conveyor with a
  • Figure 2 shows a thread conveyor with a
  • Figure 3 shows the thread conveyor of the figure
  • FIG. 1 shows a first thread conveyor device with a driven conveyor drum 2, the jacket of which is designed as a conveyor surface 4.
  • a thread 6 to be conveyed is first passed over a grooved drum 10 which is arranged on a pivotable boom 12 and is biased against the conveying drum 2 by means of a spring 14.
  • the circumferential groove drum 10 is provided with a helical groove loop 16, in which the incoming thread 6 is guided back and forth over the conveying surface 4 of the conveying drum 2.
  • the thread 6 wraps around the conveyor drum 2 over a certain area and is removed from the conveyor drum 2 by means of a guide drum 18.
  • the depth of the grooved loop 16 can be designed such that the thread 6 to be conveyed is not completely received in the grooved loop, but projects beyond the circumference of the grooved drum 10, so that the grooved drum prestresses the thread 6 against the conveying surface 4 of the conveying drum.
  • the grooved drum 10 is driven by frictional engagement with the conveyor drum 2.
  • FIGS. 2 and 3 show a further thread conveying device in which the conveying surface 4a is formed by a conveying belt 30 which is guided over a drive roller 32 and a deflection roller 34.
  • the thread 6, coming from a bobbin 36, is guided over a thread brake 38 and then continues over a grooved drum 10a, which feeds the thread 6 to the conveyor belt 30 in a reciprocating manner.
  • a pressure roller 40 presses the thread on the inlet side against the conveyor belt 30 and a take-off roller 42 guides the thread away from the conveyor belt 30 again.
  • the grooved drum 10a moves the thread by the amount X transversely to the conveying direction over the width of the conveyor belt 30, as can be seen in particular from FIG.
  • the grooved drum is freely rotatable and is driven by the thread 6.
  • such a grooved drum can be adjusted in the axial direction or can additionally be moved back and forth in order to further change the path of the thread.
