Definitions

  • the invention relates to a contactor for a loom with the features of the preambles of claims 1 or 14, in particular for a shuttle loom for producing a fabric with both sides woven edges, and a weaving method and a loom with such a shooter.
  • the shooter carrying a shovel through a shed stands with changing handover from one side of the loom to the other constantly in connection with at least one machine part of the loom, during a transfer period with a left and a right handover part.
  • the firing coil stores a weft thread, which is to be alternately laid between the sides of the machine through the shed.
  • the control of the weft yarn is a problem not only in weft insertion for the production of wide fabrics, because of increasing quality requirements even with narrow fabrics. Often, in known methods, the weft thread is too heavily loaded or unclean woven, because the weft thread is uncontrolled or unwound too slowed.
  • the object of the invention is to make the weaving method or machine parts of the loom more economical and / or to improve the quality of the fabric.
  • a contactor according to the invention according to a first variant has an actively drivable trained on the firing spool drivable with a drive which is intended at least for two influences of the firing coil, namely either to accelerate a weft delivery or delay.
  • Such a drive allows the use of standardized weft rolls, in particular for receiving a commercial yarn or Rovingrolle with cardboard or plastic core, so Umwickelvone are avoided. Incoming damage to the yarn or other wound materials are prevented. Elaborate thread compensation devices or thread brakes are not required, since the settlement can be controlled by means of the drive. It can even preventive process steps or courses are implemented, where previously only a reaction to shooter movements has occurred. A controlled or regulated Interaction of the shooter drive with the Schussspulenantrieb is possible. For example, according to a method according to the invention, the firing coil is accelerated in advance in order to avoid high thread tensions during the acceleration phase of the plug-in contactor. There are large weft inventories manageable.
  • the drive is arranged as a particular single drive stationary on the plug contactors.
  • a drive for the firing coil is arranged on each of the transfer parts.
  • the drive is an electric servo drive or a pneumatic drive, in particular designed as a friction wheel drive.
  • Such drives are available at low cost and easy to integrate in controls.
  • the firing spool has a spool holder for receiving a standardized weft thread roll, which itself can be frictionally driven from the inside inwards according to an embodiment of the invention.
  • the drive for the firing coil acts directly and thus torque-transmitting, in particular torque-controlled, on a friction wheel or a sleeve.
  • the friction wheel preferably rolls up at least temporarily an impeller of the firing coil.
  • the sleeve receives the spool holder for torque transmission in coaxial alignment, in particular without mechanical intervention.
  • the connecting parts are formed as a single carriage with internal, aligned in the weft direction guide holes for receiving a guide device, which guides the tension roller in the weft insertion direction movable.
  • the tension roller is aligned with its axis of rotation in the warp direction.
  • the weft thread particularly preferably passes through a housing which surrounds at least the shute coil at least partially surrounding it.
  • the pluggable according to the second variant according to the invention has a firing spool aligned in the warp direction, whereby the pluggable according to the first variant advantageously also has a firing spool aligned in the warp direction.
  • This orientation is particularly advantageous when weaving a so-called carbon roving, because deflections and twists are completely avoided.
  • the advantage of the alignment of the quill alone is sufficient, as far as quality standards are concerned, so according to a drive gem. If necessary, the first variant can also be dispensed with.
  • the alignment of the idler in the warp direction is also advantageous for automated weft exchange because of better accessibility.
  • a weaving machine equipped with a plug-in contactor according to the invention preferably controls the drive of the plug-in contactor in dependence on weft yarn tensiones measured via the weft bobbin or in dependence on travel / time specifications.
  • a weaving method according to the invention preferably controls the drive of the contactor in dependence on the weft tension.
  • FIGS. 1 and 2 The same components are the embodiments overarching provided with the same reference numerals. Not all figures are all reference numerals in order to give a better overview.
  • the Figures 1 and 2 show a first embodiment of a contactor 10, 10.1 according to the invention with a aligned in a warp direction 23 weft coil 12, 12.1.
  • the firing spool 12. 1 is fastened on one side to a carriage 32 with an axis 19, so that a standard weft roll 17 arranged rotatably on it can be unwound.
  • the weft roll 17 can be pulled into a free working space, so that an automated change of such weft rolls is possible.
  • the carriage 32 is always slidably received by at least one transfer part 5, 6 of a loom not shown in weft insertion 21, because as usual a transfer through a gap 37, 37.1 must be ensured with constant engagement of at least one weaving machine part, if certain qualities and process certainties are required.
  • the transfer parts 5, 6 have the plug contactors 10 facing stops 33, 34 on which ajar the contactor can preferably be locked, for example, magnetically, after the transfer from a first side of the machine 25 to the other 26 is done.
  • the firing coil 12.1 the carriage 32 facing an impeller 11 that rotates together with the firing coil, so take a torque and can deliver to the firing coil.
  • Friction wheel drives 30, 30.3 for a rolling contact with the impeller 11 on the transfer parts 5, 6 are arranged on the left and right of the firing spool 12.1.
  • friction wheel drives 30.3 driven friction wheels 35 are then in contact with the impeller 11 and can then in particular If the carriage 32 is secured against one of the stops 33, 34, this torque is transmitted to the firing coil in a manner dependent on the weft tension voltage or controlled according to travel / time specifications.
  • the left stop 33 facing the carriage 32 consists of a left connection part 15 with a corresponding receiving device.
  • the carriage has a further receiving device, adapted to the right handover part 6, of a right-hand connection part 16.
  • the guide device 31 is gem. first embodiment of pins that are guided positively in the movement of the carriage 32 in guide holes of the carriage 32. Pins and pilot holes are aligned in the weft insertion direction.
  • the firing spool 12.1 has on the axis 19 rotatably a spool holder 18 which serves to receive the stardized weft roll 17, on which a weft thread 20 is stored.
  • a spool holder 18 which serves to receive the stardized weft roll 17, on which a weft thread 20 is stored.
  • commercially available yarn or roving rolls with cardboard or plastic core can be picked up and handled in a controlled manner as a success of the invention. Saved are thread compensation and / or deflection as well as the otherwise necessary Umwickelluie known pluggable.
  • Fig. 3 shows a second embodiment of a pluggable 10.2 according to the invention, which receives a weft in the direction of insertion 21 aligned weft coil 12.2.
  • the spool 12.2 changes with its single spool holder 18.2 from a left 25 to a right 26 sleeve 36 when the direction of movement of the shooter 10.2 changes.
  • the sleeves 36 are arranged on the plug shooters 10.2 facing ends of the transfer parts 5, 6 and have the respective machine side facing stops 33.2, 34.2, against which the recorded shooting coil 12.2 is at least indirectly lockable.
  • the sleeves 36 are therefore to be understood as a further form of a guide device 31.2, which has always led the shooters 10.2 over the gap 37, 37.2 away.
  • the sleeves 36 are non-positively driven by a respective servo drive 30.1, which is arranged on the respective transfer part 5, 6.
  • Fig. 4 shows a third embodiment of a pluggable 10, 10.3 invention comparable to the first embodiment.
  • the difference is mainly in the design of the drive 30, in the present case as a pneumatic drive 30.2.
  • This embodiment could be used in explosion-proof rooms.
