Definitions

  • the present invention relates to a device and a method for weft insertion on a rapier loom. It is provided that two weft threads depending on the pattern optionally enter simultaneously in a shed, these weft threads remain separated from each other during the weft insertion.
  • the weft thread is struck in a known manner by a reed to the already existing tissue, the warp threads are placed in a weaving dependent new position, so that a new weaving cycle can begin with a new weft insertion in a new shed.
  • a particular weft yarn can be selected from such a weaving machine from a number of different weft yarns kept ready on the supply reels for each weaving cycle depending on the weaving pattern, presented to the handler and entered into the shed.
  • Such a device for pattern-dependent selection and presentation of weft threads is for example from US 4785856 A known.
  • the DE 1710292 A1 describes a device consisting of a Bringer gripper and a Holer gripper with which weft threads can be entered into a shed.
  • the grippers consist of a gripper head and a gripper bar, which are alternately advanced by a gear in the shed and pulled back. It gripper heads are used, the Hold weft with clamping levers. These clamping levers are opened by a control device for receiving or releasing the weft thread or closed by spring force.
  • the selected weft thread is presented to the bringer rapier head, the selected weft thread is brought into the movement path of the bringer gripper at an angle to the weft direction.
  • the guide element consists of a crescent-shaped guide opening in the main body of the Bringer rapier head.
  • the clamping lever of the Bringer rapier head is opened at the time of the original and closed again after picking up the weft thread.
  • the Bringer rapier head is provided with an element-to-leadership and with a member for clamping the weft thread, so that between these two elements a weft thread portion exposed in the gripper head, which is of a clamp of the holer gripper can be detected.
  • the detection of a weft thread by means of a Bringer gripper head is also possible by the weft thread is drawn into a spring-loaded clamp, without this being opened by means of a control device.
  • a technique discloses, for example, the EP 0 441 099 A1 .
  • the open leadership of the weft thread consists of a bent sheet metal, which is integrated into the main body of the Bringer rapier head.
  • the means for clamping the weft thread consists of a spring-loaded clamp with clamping parts which are shaped such that they form an insertion funnel, in which the weft thread is clamped, once it has been brought by the selection and presentation device in the movement path of the Bringer gripper.
  • Between the open guide and the clamp again creates a free section of the weft thread, which can be detected by the transfer to the Holer gripper of this. In the After transfer, the clamp is not opened, but the weft thread is pulled out of the closed clamp.
  • the EP 1135548 shows a Bringer-Geiferkopf, clamped in the two weft threads to be entered at the same time by a common terminal in the Bringer rapier head, but guided in different slot-like opening contours in the Bringer rapier head and thus partially separated during weft insertion.
  • the EP 0 695 820 discloses a holer rapier head in which different weft threads are each clamped by a separate clamping blade. This should be entered simultaneously and safely with multiple weft threads with different thread textures with a rapier head.
  • the object of the present invention is to provide a device and a method for weft insertion on a rapier weaving machine, in which it is provided to enter, from a total of two or more weft threads depending on the pattern, for each weaving cycle optionally simultaneously two weft threads in a shed, wherein the weft threads in the gripper heads remain substantially separated from each other during the simultaneous weft insertion of both threads.
  • a device for weft insertion comprises a Bringer gripper and possibly also a Holer gripper with which weft threads can be entered into a shed.
  • the grippers consist of a gripper head and a gripper bar or a rapier band, which are advanced in a conventional manner by a transmission alternately into the shed and pulled back. The movement of the gripper in the shed takes place between a reed level and the edge of the already existing tissue to which a registered weft yarn is struck.
  • the device according to the invention comprises means for pattern-dependent selection and presentation of weft threads, which are kept ready on supply reels. By a pattern-dependent programming, it is possible to select only one or two weft threads simultaneously from a number of several stocked weft yarns and submit to a gripper.
  • the elements for guiding the weft threads are of the type that a weft thread which comes by the movement of the gripper in the region of the respective guide element, can be detected and taken away by this.
  • Open guide contours according to the invention are e.g. half-sided eyelets or hooks, deflecting pins, baffles or hook-shaped contours on the main body of the gripper head. All such guide elements have in common that they have a contour, ie an edge or a surface on which the weft thread only rests when it is detected by the gripper head during its movement.
  • open guide contour in the sense of the present invention thus designates a guide element which impedes the movement of the weft thread relative to the gripper head in at least one direction transverse to the longitudinal extent of the weft thread, but its unlimited movement in at least one other direction transverse to the longitudinal extent of the weft thread and an unlimited Movement of the weft thread in its longitudinal extent allows.
  • clamping consist of clamps on a clamping lever or spring loaded, passively openable terminals through the thread.
  • actuators piezo, pneumatics, magnets
  • Bringer rapier head here is a gripper head referred to, which transports the weft thread after its detection by means of a forward movement through the shed; Forward refers to the direction to the hook tip.
  • Holer rapier head here refers to a rapier head, which, after its detection, transports the weft thread through the shed by means of a backward movement; in this case, backwards designates the direction away from the gripper tip.
  • the weft yarn as a result of the above-described function of the open guide contour, for example after being presented to a bringer rapier head, can be detected by the open guide contour in forward movement of the bringer gripper, while being released from the open guide contour in a backward movement , In a holer rapier head, the function of the open guide contour is reversed with respect to the directions of movement.
  • the open guide contours and the weft thread clamps are arranged in the bringer rapier head such that a portion of the weft yarn remains between the clamp and guide, e.g. can be detected by the terminal at the transfer to a Holer gripper head.
  • the device according to the invention it is provided that in the Bringer rapier head different from each other open guide contours when receiving the weft thread in each case in such a Position are that with two simultaneously presented weft threads each of a different open guide contour is detected.
  • the two weft threads must be brought by the selection and presentation facilities at two freely programmable, different positions in the movement path of the Bringer gripper.
  • the position of one of the two open guide contours in Bringer rapier head in the presentation of the weft thread with respect to the position during weft insertion further up and closer to the hook tip than the position of the other of the two open guide contours.
  • the open guide contour is attached to a lever which is mounted in the gripper head and can be mechanically or electrically rotated by suitable actuating means in one or the other position.
  • the further to the hook tip position is used to keep the respective weft yarn separated when entering the other weft.
  • the higher position is only needed when picking up the weft thread presented.
  • weft insertion itself is a lower position makes sense, otherwise there is a risk that the open foundedskontur.Win the area of the shed detects one of the transverse to the weft insertion warp threads and tears off.
  • both weft yarns can be clamped by the same clamp of the bringer rapier head, since the open guide contours, rather than the clamp, are closer to the reed level, thus providing the open guide contours for separation during weft insertion.
  • the various positions of the weft threads presented in the trajectory of the Bringer gripper are inventively possible, for example, characterized in that the selection and presentation facilities are arranged differently or differently driven that for one of the two weft threads another template position with respect to the Trajectory of Bringer Claw yields as for the other weft.
  • freely programmable, modular electromotive drive devices can be mounted at different heights in the vertical position above the movement path of the bringer gripper.
  • the lying closer to the gripper tip of the Bringer gripper stage is higher than the more distant from the gripper tip stage.
  • the arrangement must be such that the rear of the two weft threads, after being grasped by the gripper, can slide over this higher front step without being damaged.
  • the device according to the invention also has a Holer gripper head open guide contours, which have such a distance from each other that each of the two simultaneously registered weft threads is detected by its own open guide contour and thus the two weft threads are registered with sufficient distance from each other.
  • the associated terminal may also have separate clamping elements. Each of these clamping elements clamps only one of the two simultaneously registered weft threads.
  • the Bringer rapier head is taken after receiving the weft thread from the side where the selection and presentation devices are arranged in a forward movement over the entire width of the shed to the opposite side, where he releases the weft again.
  • the Bringer rapier head moves this first from one side of the weaving machine through the whole shed, takes on the opposite side of the weft thread and transports this in a backward motion through the whole shed. In both cases, any selection and presentation of the weft threads and a separation of two simultaneously registered weft threads during transport is possible.
