Definitions

  • the invention relates to a method for the pneumatic insertion of the weft into the weft magazine of the weft carrier of a multi-system weaving machine, in which the weft magazines of the weft carrier are each successively loaded with a cut weft piece in such a way that the weft piece is conveyed into the weft magazine by means of an air jet is, the air jet is moved during loading with the weft thread carrier.
  • the invention relates to a device for performing this method, with an injected with compressed air injector to which the weft thread can be fed from a thread measuring and delivery device and which is arranged close to the path of movement of the weft thread carrier of a multi-system weaving machine and along part of this path of movement in the same direction as a weft thread carrier movably mounted and coupled with a correspondingly directed movement driving device which is synchronized with the movement of the weft thread carrier.
  • multi-armed deflection wheels are provided in the path of movement of the loomers, and their arms are designed to accommodate one loomer, each rotating around parallel axes.
  • the shooters picked up by the arms of the revolving deflection wheels are moved synchronously over a certain angular arc of, for example, 120 or 180 °, so that the mouth of an outlet nozzle lying in one arm of the deflection wheel is opposite a thread inlet opening of the assigned shooter and is fed with a cut weft piece can.
  • the weft piece is conveyed into the weft magazine by means of an air jet while the weaving machine is running, the outlet nozzle and thus the air jet being moved with the weaving machine during loading.
  • each weaving shifter necessarily moves at the same speed as the associated outlet nozzle during the loading of its weft magazine, the inserted weft thread is piled up in the weft magazine and compressed into a plug consisting of zigzag-like thread loops.
  • the result of this is that there is a risk that the weft thread will not be pulled smoothly out of the weft thread magazine during the weaving in, but that the individual thread loops of the stopper will get caught in one another and form knots.
  • the invention has for its object to feed the weft carrier of a multi-system weaving machine pneumatically within a short, lying between two adjacent fabric sections or webs of movement of the weft carrier with the weft thread required for the respective fabric section width, without thereby accumulating the weft at one point Weft magazine of a weft thread carrier or an inadmissible strain on the weft thread would occur or an extension of the weft thread magazine of the individual weft thread carriers would be necessary.
  • the air jet conveying the weft thread is moved at a lower speed than the weft thread carrier during the loading of a weft thread magazine, it executes a relative movement to the weft thread carrier, with the result that the weft thread is distributed evenly over the individual chambers of the weft thread magazine in which separate thread sheets are stored, which can not intertwine. This prevents the weft thread from being compressed into a stopper.
  • This relative movement of the air jet to the weft carrier during the loading of the weft magazine also ensures that a longer time is available for loading the weft magazine compared to an air jet coming from a stationary injector, which can be used for this purpose without undue stress of the weft thread either increase the speed of the weft thread carrier, and thus the work performance of the entire weaving machine, significantly and / or insert longer weft thread pieces and thus produce particularly wide fabric webs.
  • the difference between the speed of each weft thread gers and the slower moving air jet in such a way that - as mentioned - no accumulation of the weft occurs at one point of the weft magazine, but there is a uniform distribution of the weft in the weft magazine.
  • the air jet In order to utilize the entire magazine length, it is expedient for the air jet to be shifted relative to the weft thread carrier by an amount corresponding to the length of the weft magazine during the insertion of the weft thread into the weft thread magazine.
  • the weft yarn is at least partially guided laterally on its way to the air jet, which happens, for example, as a result can that the thread path runs through a preferably transparent plastic tube or a plastic hose.
  • the air jets can be selected according to the program for inserting the weft into the weft magazine. An electronic repeat control can be used for this.
  • the use of two air jets can also save time when filling the weft magazine of the respective weft carrier. After the insertion of the weft into a weft magazine has ended, the air jet takes a certain time to return to its starting position; if only an air jet is used, this return time cannot be used to fill a weft magazine.
  • the weft When the insertion of the weft into the weft magazine is completed, the weft is cut off at the edge of the fabric; It is particularly expedient if its end is automatically retracted into an injector generating the air jet when the air jet is returned to the starting position, so that it does not protrude from the injector when the next weft magazine is loaded, which leads to the risk of tangling, etc. could bring with it.
  • the device for carrying out the new method mentioned at the outset is characterized in accordance with the invention in that the injector is driven by its drive device at least during the insertion of the weft thread into the weft thread magazine of the respective weft thread carrier, starting from an initial position via a predetermined path at a predetermined speed reduction ratio the speed of the weft thread carrier is driven slower speed.
  • a slide guide can be arranged in the vicinity of the movement path of the weft thread carrier, on which the injector is slidably mounted.
  • This sliding guide expediently consists of two parallel guide rails, between which the injector having a fitted sliding piece is guided.
  • the arrangement can be such that the drive device has a driver which can be automatically brought into engagement with the injector in the starting position and which can be uncoupled automatically from the injector after passing through the predetermined path, the injector then having a becomes effective, which brings it back into the starting position, which has about a return spring tension that can be tensioned when the injector moves with it.
  • the drive device i.e. H. the chain is expediently driven via a toothed gear which is in engagement with a toothing on a part of the weft thread drive which is moved together with the respective weft thread carrier.
  • the driver releases the injector so that it can be quickly returned to the starting position, from where it is moved forward either in synchronism with the next weft carrier either by the same driver or the next driver of the chain.
  • a thread guide element is arranged in the thread path of the weft to the injector, through which the At the end of the insertion into the weft magazine, the weft thread is held at a point from which the thread travel path to the injector returned to the starting position is longer than to the injector which is moved to the end of its path.
  • the device can have a plurality of injectors, each of which is associated with its own weft thread; each injector can then optionally be coupled to the drive device.
  • the injectors can be arranged next to one another to the side of the movement path of the weft thread carrier, one injector in each case being able to be moved into the starting position for the co-movement by means of an adjusting device.
  • the injectors can each be mounted between two guide rails, while the guide rails themselves are adjustably mounted transversely to the path of movement of the weft thread carriers.
  • the guide rails are adjusted laterally, so that ineffective injectors can now return to their starting position without hindrance, while the injector intended for the next filling of the weft magazine moves into the starting position for the co-movement and there comes into engagement with the drive device.
  • the injectors can also be arranged in a register which is adjustably mounted transversely to the movement path of the weft thread carrier. After the respective filling process, the register is shifted in the interval until the next weft magazine is filled so that the injector with the desired weft color is brought into the starting position for movement with the next weft carrier.
  • This adjustment of the register can take place, for example, via a rack and pinion drive inevitably as a function of the movement of the weft thread carriers in accordance with a program which is contained on a suitable program carrier, for example a punch card or a cam chain or in a memory.
  • a suitable program carrier for example a punch card or a cam chain or in a memory.
  • the injectors can be preceded by a measuring and delivery device which has a permanently driven thread drum, against the surface of which the weft threads of the injectors can be pressed at times by means of pressure rollers, the pressure movement of the individual pressure rollers being controlled as a function of the injector movement.
