Definitions

  • the invention relates to a weaving machine according to the preamble of claim 1.
  • a loom of the type mentioned is known from DE-PS 625 733.
  • the regulator i.e. the goods take-off device is stopped and the downshift transmission switches the shedding device and the control device, which are formed from the dobby and a card prism, back.
  • Such a configuration of the device for picking weft is only suitable for slow-running weaving machines and nevertheless contains the risk that when the weaving machine is restarted, weaving points are visible in the web.
  • the object of the invention is to design a weaving machine of the type mentioned at the outset in such a way that it is possible to search for a weft in a fast-running weaving machine without the risk of defects in the web.
  • control options and the response speed are significantly improved by the electronic design of the control device.
  • the connection of the control device with the downshift transmission enables the automatic downshift transmission to be controlled exactly automatically, so that it can be automatically optimally adjusted to the respective shot search process. It is also possible, when switching back the goods take-off and possibly the chain lowering and / or when Switching back the web program to take into account adjustable correction factors.
  • the electronic switching back of the weaving program when the shedding device runs forward has the further advantage that the shedding device can be designed according to optimal high-performance aspects that can prevent a return.
  • An embodiment of the weaving machine according to claim 4 is also particularly advantageous in order to prevent the downshift transmission from running on and thus to increase the precision of the weaving machine.
  • An embodiment of the weaving machine according to claim 5 is particularly advantageous since it is then not necessary to uncouple the goods take-off device and, if appropriate, the warp let-off device from the main drive of the weaving machine.
  • a particularly advantageous embodiment of such a superposition gear is described in claims 6 and 7.
  • An embodiment of the weaving machine according to claim 8 and in particular according to claim 9 is advantageous, since it enables fully automatic operation of the weaving machine.
  • the shedding device can be designed as a treading device, but it is preferably designed as a dobby according to claim 11.
  • Figures 1 to 4 show a first embodiment of a weaving machine, a warp let-off device 2, a goods take-off device 4, a shedding device 6, a main drive 8 with a drive motor, not shown, a downshift gear 10 connected to the warp let-off device 2 and the goods take-off device 4, and an electronic Has control device 12.
  • a reed 14 and a weft insertion element 16 are connected to the main drive 8 in a manner not shown in detail, for example, from CH-PS 633 331.
  • the warp let-off device 2 contains a warp beam 18, the shaft 20 of which is driven by a worm gear 22.
  • the warp threads 24 pass from the warp beam 18 via a match beam 26 to the shafts 28 of the shedding device 6, which serve to form and change the warp shed 30.
  • the weft insertion element 16 engages periodically in the warp pocket 30.
  • the registered weft thread is attached to the fabric edge 32 by means of the reed 14.
  • the woven fabric 34 is stretched over the draw boom 36 and pulled off and rolled up on the fabric tree 38.
  • the goods take-off device 4 containing the pull boom 36 and the goods tree 38 is driven by a regulating gear 40.
  • a secondary drive shaft 46 is connected to the main drive 8 via bevel gears 42, 44 to drive the warp let-off device 2, the goods take-off device 4 and the shedding device 6.
  • This carries a gear 48, which drives a drive wheel 52 for the warp let-off device 2 and the take-off device 4 and a drive wheel 54 for the shedding device 6 via a toothed belt 50.
  • the shedding device 6 contains a dobby 56, the drive shaft 58 of which is optionally connected to the drive wheel 54 with the interposition of a clutch 60.
  • the Dobby 56 which is constructed and controlled, for example, according to EP-OSen 0 056 098 and 0 068 139, has shaft rockers 62, which are each connected to a shaft 28 via a lever drive 64.
  • the drive wheel 52 for driving the warp let-off device 2 and the goods take-off device 4 is connected via the downshift gear 10 designed as a superposition gear to a drive shaft 66 which drives the worm gear 22 of the warp let-off device 2 on the one hand and the regulating gear 40 of the goods take-off device 4 on the other hand.
  • the drive wheel 52 is arranged on a bearing sleeve 68 which is rotatably mounted on the drive shaft 66.
  • the bearing sleeve 68 protrudes into a housing 70 and carries a gear 72 with which a planet gear 74 meshes.
  • the latter is rotatably arranged on a shaft 76 which is rotatably mounted in a planet carrier 78 which in turn is rotatably supported on the drive shaft 66.
  • a further planet gear 80 is connected in a rotationally fixed manner to the shaft 76 on the shaft 76.
  • the second planet gear 80 meshes with a gear 82 which is arranged on the drive shaft 66 in a rotationally fixed manner.
  • the planet carrier 78 is designed as a worm gear and contains on its periphery a worm gear 84 which cooperates with a worm gear 86, the drive shaft 88 of which is connected to an auxiliary motor 90.
  • the worm gear formed from the worm gear 84 and the worm wheel 86 is preferably designed to be self-locking.
  • the downshift transmission 10 is also equipped with a braking device 92 to prevent overrun.
  • the brake device 92 has a friction disk 94, which is arranged on the drive shaft 88 in a rotationally fixed manner, with which a friction disk 96, which is arranged in a rotationally fixed manner in the housing 70, interacts.
  • a pin 98 arranged on the friction disk 96 engages in a groove 100 in the housing 70, which is parallel to the drive shaft 88 and prevents rotation of the friction disc 96.
  • a biasing spring 102 biases the stationary friction disk 96 against the friction disk 94 connected to the drive shaft 88.
  • the drive shaft 66 is interrupted by means of a clutch 104 on the part going to the warp let-off device 2.
  • This clutch is designed, for example, as a claw clutch, which can be switched via a shift lever 106 and an actuating device 108, so that the drive of the warp let-off device 2 can be switched off if necessary.
  • the weaving machine is equipped with the electronic control device 112, which is connected on the one hand to the dobby 56 of the shedding device 6 and on the other hand to the auxiliary motor 90 of the downshift transmission.
  • the electronic control device which is expediently provided with a processor, enables the weaving program to be switched back when the weaving machine runs forward, so that the dobby 56, which is driven in the forward direction, executes a reversing movement sequence.
  • the control device controls the auxiliary motor 90 of the downshift transmission 10, so that the warp let-off device 2 and the goods take-off device 4 can be switched back for the purpose of searching for weft threads.
  • the downshift transmission also has the advantage that the goods take-off device 4 and optionally the warp let-off device 2 can be moved forward or backward even when the weaving machine is at a standstill.
  • FIG. 5 shows the weaving machine of FIG. 1, but the downshift transmission 10a is not driven by an auxiliary motor but by the main drive 8 of the weaving machine.
  • a secondary drive shaft 112 is connected to the main drive 8 via a clutch 110, which drives the drive shaft 88 of the downshift transmission 10a via a toothed belt drive 114.
  • the rest of the structure of the downshift transmission 10a corresponds to that of FIGS. 3 and 4.
  • the clutch 110 is configured, for example, as a dog clutch, a shift lever 116 being connected to an actuating device 118, which in turn is connected to the electronic control device 12.
  • This downshift gear 10a can only be actuated when the main drive 8 is running.
  • FIG. 6 shows a further downshift transmission 10b, which in turn is arranged on the drive shaft 66.
  • the drive wheel 52 connected to the main drive 8 is in turn rotatably arranged on the drive shaft 66 via the bearing sleeve 68 and projects into a housing 120 which in turn is rotatably supported on the bearing sleeve 68 via a bearing 122 and on the other hand via a bearing 124 on the drive shaft 66 is.
  • a bevel gear 126 which meshes with a second bevel gear 128, which is rotatably mounted in the housing 120, is fastened to the bearing sleeve 68 within the housing 120.
  • This second bevel gear 128 in turn meshes with a third bevel gear 130, which is arranged on the drive shaft 66 in a rotationally fixed manner.
  • a worm wheel 132 is fastened coaxially to the drive shaft 66, which interacts with a worm 134, the drive shaft 136 of which is connected to an auxiliary motor 138.
  • a braking device 140 serves to prevent the overrun of the downshift transmission 10b.
  • the mode of operation of the downshift transmission 10b is similar to that of the downshift transmission 10 of FIGS. 3 and 4.
  • the function of the planet carrier of the downshift transmission 10 is carried out by the housing 120 in the downshift transmission 10b.
