Definitions
- the present invention relates to a weaving machine.
- the Web ⁇ machine for example, has a dobby or a jacquard.
- Jacquard machines are used to create any pattern in connection with weaving or knitting machines.
- Dobby machines are used to produce coarser patterns, especially in connection with weaving machines.
- the weaving machine has, in an advantageous embodiment, a basic machine.
- a warp beam is playing interchangeable at ⁇ .
- the Jac ⁇ is quardmaschine or the dobby, by means of a propeller shaft of a basic machine or by its own drive with egg ⁇ nem transmission which may also include a separate rate main shaft driven.
- the shaft or Jacquard machine is connected directly or via gear or electronic synchronization with the main shaft of the loom.
- the electronic synchronization with respect to the main shaft corresponds to the principle, for example, of an electronic vertical shaft in a printing machine.
- the term of the line shaft by ⁇ failed det only in the fact that the concept of the main shaft it is mixed in looms typically applies and the term vertical shaft in printing machines. From the concept of the main shaft The technical function is the same.
- the main electronic ⁇ wave serves as the electronic line shaft, bringing about a synchronized movement ⁇ guide.
- the cardan shaft or the gearbox are expensive and subject to wear.
- a compartment opening time is inversely proportional to a main shaft speed of the loom and thus determined only by this.
- a certain shed opening angle is given.
- the object of the present invention is to overcome the disadvantages described above. It is advantageous ge ⁇ geous to allow a compact design as well as the wear of mechanical parts of the loom zuu ⁇ reduce. Furthermore, it is an object of the present invention to increase the compartment opening time.
- a loom according to the invention which has a shank ⁇ machine or a jacquard machine, wherein the Web ⁇ machine with the dobby or weaving machine with the Jacquard machine by means of an electronic main shaft ge ⁇ coupled, the dobby or the Jacquard machine on a direct drive ,
- the dobby or Jacquard machine are therefore driven directly.
- di ⁇ rect drive it is possible th to a transmission to verzich ⁇ .
- This cost is einsparbar and a compact Bauwei ⁇ se possible.
- Another advantage is that a gear is subject to wear and this wear is now no longer given. This can increase the operating time of the weaving machines.
- a hitherto usual connection of the Jacquard machine via a cardan shaft with a main shaft of the loom is therefore eliminated.
- Achieving the synchronism of the loom or basic machine with the dobby o- or the jacquard machine is ensured by means of an electronic main shaft.
- the electronic main shaft ⁇ it enables an electronic synchronization of drives in both the loom and in the dobby or in the Jacquard machine.
- the direct drive is a torque motor.
- the torque motor is powered by a feders.
- the torque motor is coupled via a geeigne ⁇ te control means of an electronic cam to a main shaft of the loom.
- the electronic cam can be designed in such a way that a compartment opening angle is greater than a construction with a mechanical drive of the jacquard machine or dobby.
- Weft thread (eg strength, inertia, roughness, ...) oppose.
- a 1: 1 coupled Dobby the relative compartment opening time is always the same, that is with the ⁇ He heightening the main shaft speed, the absolute shed opening time is getting smaller. If the dobby in the win ⁇ angle range in which the subject is changed, spinning faster and rotates more slowly in the open shed area, the relati ⁇ ve shed opening time is increased so that this only at a height ⁇ ren main shaft speed, the critical minimum Schussein-'s contribution period reached , Since the warp threads are more heavily loaded in this method due to the faster change of subject, the parameters relating to the method are to be optimized.
- both ei ⁇ ne magnification is meant the maximum angle as well as an increase in the time in which an angular range sufficient er ⁇ is that enables the shot of weft threads.
- the increase in the shed opening time is the speed of the loom Anlagenge ⁇ be enlarged, so that this operates ef ⁇ maschineiver.
- This improvement is co-founded in the elimination of the transmission as a mechanical means for implementing a speed.
- To increase the shed opening time is advantageously a corresponding adapted electronic ⁇ cal cam in the control of the loom and / or stored in the control of the jacquard and / or in the Steue ⁇ tion of the dobby.
- the control of the weaving machine is either separate from the controls of the jacquard machine or the dobby or the controls are integrated in one device.
- the control of the direct drive he follows ⁇ example by means of the control of the loom or jacquard or the dobby.
- the concept of control here includes both control as well Rege ⁇ control tasks.
- the Schaftma ⁇ machine or Jacquard machine has no gearbox.
- a gearless driving of the Jac ⁇ quard machine or the dobby is made possible.
- shed opening angle of the dobby or Jacquardma ⁇ machine is by means of an electronic cam striking flow ⁇ bar.

- the Schaftma ⁇ machine 7 is provided for the movement of shafts 5, wherein the dobby is in turn driven by signals.
- the shafts 5 belong to the weaving machine.
- the dobby 7 is rotationally connected to the main shaft of the weaving machine; on the output side, the dobby is translationally connected to the individual shafts. Which shaft has to be raised or lowered in the current revolution of the weaving machine and dobby is given by the electrical control of the dobby.
- the weaving machine has an operating device 9, egg ⁇ ne control 11, a reed 17 and a cloth tree 15 for rearing up woven goods 13.
- a shed 3 is formed by the warp deflected by the shafts.
- the view according to FIG. 2 shows a shed opening angle ⁇ 23.
- the shed opening angle 23 results from the angle of warp threads 41 that are spanned. In the case of a jacquard machine all warp threads are raised or lowered individually. The lifting and lowering is controlled by means of a controller.
- the shafts ⁇ NEN thereto to span the shed. For simple fabrics, for example, only two shafts are needed, for higher quality fabric several shafts can be used.
- the shafts are reciprocally moved up and down resulting in a shed opening.
- the specialist opening is synchronized to the web process.
- the synchronization was carried out according to the prior art by means of direct coupling with the main shaft of Web ⁇ machine and is now often accomplished by means of an electronic main shaft.
- the synchronization takes place with an electronic main shaft by means of a bus system.
- a jacquard selection unit which is mounted on a support frame, selectively lifts individual warp threads over harness threads, thus enabling a more flexible shed and weave pattern.
- the Jac ⁇ quardmaschine for example, has its own Steue ⁇ tion / control, which is data-technically coupled to the actual weaving machine for the purpose of data exchange.
