Definitions

  • the invention relates to a single-strand control device for a loom provided with shafts according to the preamble of claim 1.
  • DE-OS 22 04 815 now describes a single strand control device of the type mentioned, in which separate drives are required to drive the individual coupling means which control the individual strands, as is customary for jacquard machines. This results in complicated and expensive individual strand control devices which are unsuitable for retrofitting in weaving machines with shafts, both in terms of construction volume and in terms of economy.
  • the object of the invention is to provide a single heald control device which, in particular, can also be retrofitted to weaving machines with shafts, is distinguished by a simple structure and enables a large variety of variations.
  • the object is achieved by the single strand control device according to claim 1.
  • the solution according to the invention makes a separate drive of the individual strand control device unnecessary, which results in a particularly simple construction of the individual strand control device, which is not only inexpensive, but in particular also requires a small construction volume, so that there is the possibility of subsequent installation in a weaving machine with shafts.
  • this design provides the further significant advantage that the control properties of the shaft device can be used in addition to the control properties of the selection device of the single-strand control device, so that there is a greater number of control options for the single-strand control device without additional effort.
  • the control of the boards is preferably carried out according to claim 4.
  • the engagement and disengagement of the control lug is improved by an embodiment according to claim 5.
  • a particularly flat and compact design of the selection device of the individual strand control device results from claim 6.
  • several such assemblies can be arranged next to one another.
  • Figure 1 shows a
  • the selection device 2 contains coupling means 8, which are designed as circuit boards 8 and can be controlled by means of electromagnets 10 according to FIG. 5 or electromagnets 12 according to FIG. 6. These electromagnets are connected to an electronic pattern control device 14. Harness threads 16 are connected to the top of the boards 8, which are guided downward via deflection rollers 18 and further via a bar-shaped guide board 20 to the individual strands 22. The latter are biased downward, for example, by means of springs 24.
  • Strand eyes 28 arranged in the individual strands 22 serve to guide threads 28 lying in the warp direction, which are generally warp threads, but in certain cases also can be individually fed threads for special tasks, such as auxiliary threads for tying weft loops of a needle loom.
  • the selection device is described in more detail in FIGS. 4 and 5.
  • the circuit board is mounted in a housing 30 of the selection device 2 so as to be displaceable in the vertical direction.
  • a driver nose 32 which interacts with a knife 34 1 , 34 2 of a knife device 36, the latter being coupled to the shaft drive 4.
  • the circuit board 8 1 is locked in an initial position which corresponds to the extreme position of the knife 34 1 , 34 2 of the knife device, which is opposed to the pretensioning of the individual strands 22 and the harness thread 16. Accordingly, the circuit board 8 1 can only follow the movement of the knife 34 under the influence of the pretensioning of the wire if the latched state has been released, as is indicated by dash-dotted lines in FIGS.
  • a control lug 28 which is arranged on a pawl 40 1 which is pivotably mounted in the housing 30 and is biased against the circuit board by means of a spring 42, is used to latch the circuit board 8 1 in place .
  • On the control lug 38 and on the recess of the detent stop 44 bevels 46, 48 are provided on the side opposite the detent surface, which facilitate the engagement or disengagement of the control lug 38 on the detent stop 44.
  • the electromagnet 10 1 which interacts with the pawl 40 and pulls it back against the bias of the spring 42, serves to release the catch.
  • the board 8 i can then follow the knife 34 1 , 34 2 of the knife device 36 in accordance with the pretensioning of the strand.
  • the circuit boards 8 are designed as flat strips, three circuit boards 8 1 , 8 2 , 8 2 being combined to form an assembly 49 1 , 49 2 , 49 2 , in which the circuit boards lie side by side. Accordingly, there are also three electromagnets 10 1 , 10 2 and 10 2 arranged one above the other, which actuate the three pawls 40 i , 40 2 and 40 3 arranged one above the other.
  • the electromagnets are designed as flat magnets, their thickness corresponding to three times the board pitch T. This results in extremely flat assemblies that can be strung together as required.
  • Figures 4 and 5 show three such assemblies.
  • the knife device 26 can have two knives 34 1 and 34 2 , which can be controlled in the same cycle or in a different cycle.
  • the driver lugs 22 point in the corresponding direction of the knife 34 2 .
  • FIG. 6 shows a modified embodiment of the device for latching the circuit board 8, the control lug 28 being arranged on an armature 50 which is slidably mounted in the electromagnet 12.
  • the armature 50 has a stepped part 52, around which a spring 54 is arranged, which is supported on a housing cover 56 of the electromagnet 12 and biases the armature 50 against the circuit board 8.
  • This arrangement is characterized by a particularly simple construction, which, however, requires a somewhat greater lateral height than the device in FIGS. 4 and 5.
  • the shaft drive 4 consists of a treading device which contains a driven shaft 58, on which cams 60 are fastened.
  • Two-armed levers 62 which are connected to the knife device 36 via connecting members 64, act on these cams.
  • the knives 34 of the knife device 36 can be suspended analogously to the shaft frame.
  • the cams 60 of the shaft drive 4 are optionally adjustable on the shaft 58 so that the control of the individual strands can be varied further.
  • FIG. 2 shows a further exemplary embodiment of a single-strand control device, which essentially corresponds to the exemplary embodiment of FIG. 1, but with boards 8 1 , 8 2 assigned to two different knives 34 1 and 34 2 being connected to one another via a connecting thread 60.
  • a block and tackle device establishes the connection between the sinkers 8 1 , 8 2 and at least one harness thread 72, the connecting thread 66 being guided over a deflection roller 68 to which a further deflection roller 70 is connected, via which the harness thread 72 is guided.
  • This harness thread 72 is fixedly attached to a frame at one end 74.
  • the other part 76 of the harness thread 72 is in turn guided via a deflection roller to the bar-shaped guide board 20 and connected to a single strand 22.
  • the individual strand 22 executes a movement according to the so-called double stroke principle, ie one stroke per weft insertion.
  • FIG. 3 shows a further exemplary embodiment of a single-strand control device, in which the knife device 36 is connected directly to a shaft frame 80.
  • the shaft frame has an attachment 82 which acts directly as a knife, which interacts with the driver lugs 32 of the plates 8.
  • the shaft frame 80 is connected to a drive device 86 via a lever gear 84. Otherwise, the mode of operation of this single-strand control device corresponds to the single-strand control device already described above.
  • Figures 7 and 8 show the arrangement of the Individual heald control device according to FIG. 2 in a weaving machine, whose shaft drive device 88 is formed from a shaft drive 4 designed as a tread device, to which various shaft frames 90 are connected.
  • the shaft drive 4 has a drive shaft 58 to which cams 60 are fastened. Double-armed levers 62 act on these cams, which are connected via connecting links 64 on the one hand to the shaft frame 90 and on the other hand to the knives 34 of the knife device 36.
  • the stem frames 90 are suspended via biasing springs 92 in a frame 94 for the stem frames.
  • the assemblies of the selection device 2 are also fastened to this frame 94.
  • two boards 8 1 and 8 2 which are driven by two different knives 34 1 and 34 2 of the knife device 36, are connected to one another via a connecting thread 66.
  • This connecting thread is guided analogously to the embodiment of FIG. 2 via a deflection roller 98 on the frame 94 to the deflection roller 68, which is connected to the deflection roller 70 for the harness threads 72.
  • One end 74 of the harness threads 72 is fastened to the frame and the other part 76 is guided via an upper guide board 98 and the lower bar-shaped guide board 20 to two individual strands 22 1 , 22 2 .
  • two interconnected boards 8 1 , 8 2 control single strand threads 22 1 and 22 2 according to the principle of double-stroke control.
  • FIG. 8 also shows how the shaft frame 90 and the individual strands 22 1 , 22 2 control the threads 28 to form a warp pocket.
