Definitions

  • the invention relates to a method for clamping a weft thread in a jet loom, in particular air jet loom, according to the preamble of claim 1.
  • the invention further relates to a clamping device on a weaving machine, in particular air jet machine according to the preamble of claim 11.
  • the invention also relates to a jet loom according to the The preamble of claim 22.
  • a device for entering a weft thread is provided in the shed on a jet loom, which consists of a block of Hauptblasdüsen with connected mixing tubes.
  • a clamping device is provided, by means of which the weft thread located in the mixing tube is held straight in alignment before it is introduced into the shed.
  • Each of these clamping devices has an actuator located outside the mixing tube, which can be pneumatically or piezoelectrically actuated and deformed. Characterized a connected to the actuator clamping member is placed in a tilting or pivoting movement.
  • the clamping member engages in the mixing tube and clamps with its free end the weft thread against an abutment located on the mixing tube.
  • the embodiment of the actuator in the form of an elastomeric bellows, which is directly connected to the clamping member.
  • a spring or a bending elastic holding element can influence the respective position of the clamping member.
  • the clamping member itself can be elastically deformed.
  • the known clamping devices according to the DE 10 2004 036 996 B3 are already constructed of modular units of two clamping devices; several can do this Module units are combined into a block. Nevertheless, relatively little space is available for the individual clamping unit.
  • the holding force of a pneumatically actuated holding device is dependent on its size. If the dimensions must be small, the holding power is limited. The same applies to a hydraulic or piezoelectric actuation of the actuators.
  • the compressibility of the controlling air flows is still disturbing. This leads to a delayed Ans prech the clamping device.
  • the clamping member is set in the transition from its clamping position to the release position and vice versa in vibrations, so that particularly fine weft threads are no longer reliably clamped timely.
  • the delayed response of the clamping devices can already lead to disturbances in the weaving process at today's speeds of up to 1000 U / min in modern weaving machines.
  • the clamping member is located there similar to a non-return valve at the outlet of the mixing tube, where it is pivotally mounted on a hinge located outside the mixing tube and is retracted by a tension spring also located outside in the outlet opening of the mixing tube.
  • a weft thread is clamped against a shoulder which forms part of the outlet opening.
  • the blowing air flow of the main blowing nozzle which introduces the weft threads is intended to open the clamping member against the action of the spring and thereby release the clamped weft thread.
  • an exact, fast-running and precisely controllable transition from the clamping position into the release position can not be expected because the control of the clamping member inseparably linked to the transport of the weft thread.
  • the invention has for its object to provide a method and a clamping device of the initially mentioned type with which in a simple, compact design, a reliable holding power can be achieved in conjunction with an accurate response, so that a nearly trouble-free weaving operation even at high speeds the weaving machine is possible.
  • Claim 22 is directed to a jet loom having the clamping device according to the invention.
  • an amplification of the clamping force of the movable clamping member is achieved by an additional magnetic force. Since the holding and clamping force is applied essentially by the magnetic force, the components for operating the clamping device can be dimensioned smaller despite safe operation. It is thus a particularly compact design possible, so that the main blowing nozzles and mixing tubes can be arranged advantageously and as straight as possible weft yarn guide is guaranteed up to the weft insertion channel of the reed.
  • the amount of reinforcing magnetic force is advantageously adapted to the properties of the weft thread, so that an additional clamping is ensured without significantly affecting the quality of the weft thread at the nip.
  • the magnetic reinforcement is designed such that the release of the movable clamping member from its clamping position initially inhibited, but its approach to the clamping position is accelerated.
  • the holding force of the movable clamping member is magnetically reinforced in its release position. If further measures are taken to the fact that the release of the clamping member initially inhibited from its release position, but its approach to the release position is accelerated, so that overall the dynamic behavior of the clamping member in the mixing tube is influenced very beneficial.
  • the magnetic force acts on the clamping member in the first end position until the actuating force originating from the actuator is built up on the clamping member, which is larger than the attracting magnetic force. If this point is reached, then the clamping member goes almost abruptly in the second end position. As well When approaching the respective second end position, an acceleration is achieved by the attractive magnetic force.
  • the method may be performed by actuating the actuator hydraulically or piezoelectrically.
  • control of the actuator by means of a separate pneumatically acting control fluid.
  • the magnetic reinforcement in the clamping position and / or the release position of the clamping member can be made permanently magnetic in a particularly simple manner.
  • the permanent magnetic amplification is temporarily canceled by a controlled electromagnet.
  • z. B. reduces the release force for releasing the clamping member controlled from its end positions or canceled and operated the clamping device with a further lower pressure.
  • the magnetic amplification is generated by at least one electromagnet.
  • the control of the solenoid (s) is then incorporated into the loom control.
  • the clamping force can be adjusted during operation to changed yarn properties or operating conditions. If, for example, a sensitive weft yarn is processed, then the magnetic force the electromagnet and thus the clamping force of the clamping member are set to a lower value, and damage to the weft yarn at the nip are avoided.
  • Robust yarns with a smooth surface can be processed with a high clamping force to ensure that the yarns are held securely despite the smooth surface.
  • the temporal occurrence of the magnetic force to various operating conditions such as different speeds of the loom can be adjusted.
  • the invention made possible by the particularly compact design of the associated clamping device makes it possible to make the magnetic reinforcement of the clamping member at each point of Hauptblasdüse and mixing tube.
  • a particularly advantageous possibility is that the weft thread is clamped in the mixing tube, as that of the aforementioned DE 10 2004 036 996 B3 is known.
  • clamping device is provided as an advantageous development that the magnetic reinforcement is carried out by at least one holding magnet in cooperation with the clamping member not only in the clamping position, but also in the release position of the clamping member.
  • the embodiment is particularly preferred with a pneumatically actuated actuator, which is designed as Elastomer bellows, which is pneumatically controlled and deformed by overpressure, pressure equalization with respect to the environment or negative pressure and is deformed with the clamping member such that the pneumatic deformation of the elastomer bellows Tilting or pivoting movement of the clamping member for the transition from the clamping position to the release position or vice versa causes.
  • the clamping member may be attached directly to the elastomer bellows.
  • the actuator formed as Elastomer bellows is deformed or deformed by air as the actuating means, resulting in the tilting movement of the clamping member.
  • the Tilting movement when releasing the clamping member from the clamping position or the release position inhibited by the magnetic force and accelerated when approaching the clamping member to the respective opposite position by the magnetic force.
  • the reinforcing magnetic force is particularly advantageous because it not only prevents delays caused by the compressibility of the air. In addition, delays are avoided, which are caused by the resistance with which the elastomer bellows opposes in its deformation of the pneumatic actuating force. In addition, such an elastomer bellows will be deformed at least in one end position and therefore constantly oppose the clamping or holding force in this end position an opposing force; because the elastomer bellows strives to return to its undeformed initial shape.
  • the installation of the holding magnets causes the clamping member is held securely in one of the end positions even in the unpressurized state. This ensures, for example, in the release position that the clamping member does not hinder the free passage through the Hauptblasdüse and the mixing tube by being always held by the magnetic force outside the conveying air flow.
  • clamping member is arranged at a position of the mixing tube and the actuator is located outside the mixing tube, so there is a compact design, in which on the one hand the main blowing nozzles and the clamping devices can be combined in blocks.
  • the structural design in detail while in the DE 10 2004 036 996 B3 already described detailed solutions are taken advantage of.
  • the subdivision of the mixing tube in a longer initial section and a much shorter end portion is not just an emergency solution that will allow the engagement of the clamping member in the mixing tube.
  • the significantly shorter end portion of the mixing tube causes, above all, that the free end of the Weft thread after cutting the registered weft thread section can not collide with the clamping device and therefore does not strike back. By dividing the mixing tube thus takes place a decoupling of the clamping device from the thread end.
  • the arrangement of two clamping devices each with directly adjacent mixing tubes to a module unit in a first plane not only brings the advantage of compact design, but also makes it possible that at least one holding magnet can be used together for each two clamping devices; because those from the DE 10 2004 036 996 B3 known and adopted module unit causes the beginning and end portions of the mixing tube closely adjacent and mirror images of each other.
  • the actuators are provided on the outside of the mixing pipe sections; therefore, a holding magnet located between the mixing tube sections of both clamping devices may optionally be effective for both clamping devices.
  • Fig. 1 shows by way of example of a jet loom, a block 17 with four main blowing nozzles 1, to which the mixing tubes 2 connect. Via the connections 13, the main blowing nozzles 1 are supplied with compressed air, which serves to introduce the weft threads 3.

  • the weft yarns 3 through the main blowing nozzles 1 and through the mixing tubes 2 therethrough not shown weft insertion channel of a reed and thus supplied to the shed.
  • the mixing tube 2 is divided into a longer initial section 2.1 and a comparatively shorter end section 2.2. The separation point between the beginning and the end section 2.1, 2.2 is located within the clamping devices, of which in Fig. 1 a common, four clamping devices comprehensive module unit 18 can be seen.
  • the relevant weft thread 3 After leaving the end section 2.2 of the associated mixing tube 2, the relevant weft thread 3 passes into the shed, is struck by the reed at the binding point and cut off by a scissors located between the end section 2.2 and the fabric edge. Beforehand, however, the weft thread 3 is clamped in the mixing tube 2 by its associated clamping device located in the modular unit 18, so that it does not spring back into the mixing tube 2.
  • the block 17 and the module unit 18 are mounted on a common base plate 4, which serves for attachment to the sley, not shown, of the jet loom.

  • the chamber 10 is connected via a supply line 20 to the valve 16, which is a pneumatic valve in the present example.
  • the unillustrated control unit of the weaving machine controls the electromagnetically operable valve 16 and thereby can pressurize the chamber 10 of the actuator 6 with air, which is under pressure or is pressureless to the environment.
  • the clamping member .7 is connected, which is designed as a lever with a long lever arm 7.1 and an angled short lever arm 7.2.
  • the clamping member 7 is inserted into a slot which is formed in the elastically deformable actuator 6.
  • the angled short lever arm 7.2 is opposite to an engagement opening 8, which separates the mixing tube 2 in an initial section 2.1 and an end section 2.2. Beginning section 2.1 and end section 2.2 are connected to each other by an abutment 9.
