Definitions

  • the generic yarn feeding devices are used in particular at the workplace of a weaver in order to deduct the individual weaving threads and provide them in accordance with their intended use.
  • a typical application is, for example, the weaving of hairpieces in which, for example, three or more threads are manually stripped from bobbins and woven together.
  • the yarn feeding devices have for each effetspulenden thread on a clamping means over which the thread is biased in each case in a direction opposite to the withdrawal direction with little force.
  • Such yarn feeding devices are used in particular by manual workers, for example when weaving the base of hairpieces. They usually have several thread bobbins, so that the user can work with several threads.
  • the advantage here is the use of the clamping means, as they avoid the hanging and tangling of the threads during work.
  • Such a yarn feeding device for the parallel provision of three weaving threads is known from US 5,178,237 DE 10 2009 041 867 A1 known.
  • This yarn feeding device has three supply arms, on which outside of three different bobbinsfastzuspulende threads are guided through guide eyelets.
  • the clamping means are formed by weights, which hang in each case between two guide eyes on the thread.
  • a disadvantage of the known yarn feeding device is that the drooping weights and the loop of thread hanging therefrom can not preclude a certain risk of entanglement and have not appeared visually very lucrative.
  • the weight must be chosen so that on the one hand is able to keep the thread taut, on the other hand, but not so large that it falls to the ground and automatically unwinds the coil at least until it is on the ground rests.
  • the open thread guide is often perceived as less attractive.
  • a motorized yarn feeding device for looms which has a spring return for the thread with the elimination of the driving force to keep the thread on tension.
  • the spring is integrated into the coil storage.
  • Other cable or thread feeds are from the GB 1 442 261 A1 , of the US 5,000,397 A1 and the US 2002/0113159 A1 known.
  • the object of the invention is therefore to provide a yarn feeding device, which ensures a safe operation with ease of use and is as attractive as possible in the visual appearance.
  • a yarn feeding device according to claim 1.
  • the bobbin is mounted on a arranged on the feed arm bobbin, at least one limited in their deflection by a first stop thread return spring is provided to form the clamping means, which is arranged such that they act at a sufficient for the removal of the thread on the thread Traction is deflected, and the bobbin is mounted such that there is a counter to the unwinding braking force, which is greater than the spring force of the thread return spring.
  • the restoring tension which acts on the thread, should be made as user-friendly as possible.
  • the thread bobbin must be designed so that there is a braking force directed against the unwinding, so that the thread return spring is first pretensioned at a pulling force on the thread and only then does the thread unwind.
  • a clamp can be provided, over which the thread can be clamped when not in use, so that it is avoided that the thread is inadvertently pulled back into the feed arm.
  • Another aspect of the invention is the thread guide.
  • For thread guidance of the feed is designed so that through a hollow cylindrical portion of the thread can be passed.
  • a particularly convenient combination of the two aspects of the invention comprises feed arms, at one end of the thread bobbin is arranged. From there, the thread is inserted into the hollow cylindrical feed arm and exits at the front free end of the feed again.
  • the feed arm can have, for example, a slot-like thread take-up.
  • the thread can also be inserted initially with an aid, for example a push rod, through the feed arm. This concealed thread guide is perceived by many users to be particularly attractive.
  • the yarn feeding device comprises a modular structure, so that the user can individually adjust the number of working threads available.
  • the arm holder may consist of plug-together individual modules, to each of which a feed arm is attached or can be attached.
  • the bobbin is provided with the resilient mounting of the thread.
  • Another aspect may be a height adjustment of the thread guide.
  • either portion of the arm holder or the whole arm holder may be formed as a telescopic rod or the arm holder may be formed so that it is variable in height on the use of different spacers.
  • the feed arms can be extended, this can also be realized by the use of telescopic rods or by lugs that can be plugged for example on the front of the hollow cylindrical feed arms.
  • FIG. 1 a yarn feeding device is shown. Like the known yarn feeding devices, it has a base 1, an arm holder 2 arranged thereon and, in turn, feeding arms 3 arranged on the arm holder 2. At the feed arms 3, a bobbin holder 6 is arranged in the right region, which forms a bearing for the bobbin 4 here. Of this bobbin 4, as will be described in more detail below, a thread 5 performed by the feed 3 and can be removed for weaving, especially of bases of hairpieces.
  • the arm holder 2 is height adjustable. For this he is in the lower part after the manner of a telescopic rod extendable. To fix the height adjustment either pins can be provided, which are inserted into corresponding openings in the double-walled area of the arm holder 2. Alternatively, a frictional force may be present, so that an explicit fixing is unnecessary.
  • the feed arms 3 are attached to individual upper segments of the arm holder 2. These segments are preferably rotatable relative to each other and relative to the arm holder 2. This too Feature is optional, the benefit of the invention would occur even without rotation of the feed arms 2.
  • the feed arms 3 may also be variable in length, in particular designed to be extendable. For this purpose, they have a rear hollow cylindrical Area and an inserted therein front push rod. In the upper part, the feed arms 3 are provided with a slot-like thread take-up 10.
  • the user can unwind the thread 5 from the bobbin 4 and insert from above into the slot of the thread receiving 10. Since the thread 5 is usually pulled down, additional security measures against unwanted slipping out of the thread 5 from the feed 3 are usually unnecessary. However, should such a fuse be desired, this can either be the flap-like fuse described below or it can be closed particularly simply by turning the push rod relative to the rear support rod in the connecting region of the two rods of the slot. Locking means can facilitate the finding of the closed and the open position.
  • a retaining force for the thread 5 is provided. This is formed in the unclaimed embodiment shown here by a built-in bobbin 4 thread return spring 13 (not visible here).
  • the thread return spring 13 tensions the thread 5, so that it does not hang down during work and tangling of the threads 5 is largely avoided.
  • FIG. 3 it can be seen here is the bobbin 4 from a thread drum 11, which is attached to a drum holder 12.
  • the thread drum 11 and the drum holder 12 are mutually rotatable against the force of the thread return spring 13 by a defined angular range.
  • the entire assembly is rotated and the thread 5 is unwound from the thread drum 4.
  • the restoring force of the thread return spring 13 acts on the thread 5, so that when the tensile force is released by releasing the thread 5, the thread drum 4 is automatically reset by the angular range.
  • a first stop 7 and a second stop 8 are provided, as shown FIG. 7 and FIG. 8 is apparent.
  • FIGS. 7 and 8 a first possibility of an unclaimed embodiment of the thread drum 4 is shown.
  • the drum holder 12 Inside, the drum holder 12 can be seen.
  • To implement the first stop 7 and the second stop 8 a side of the drum holder 12 is provided. This consists essentially of a radius increase in this area.
  • the inside of the thread drum 11 is adapted thereto and has a running surface for this rotation angle limiter 9 over a larger angular range.
  • the ends of the tread which is formed as a groove or circular recess in the inner circumferential surface of the drum holder 12, represent the stops 7 and 8.
  • the drum holder 12 and the thread drum 11 are connected via the thread return spring 13, each with one end to one of two components is attached to each other, so that a relative movement between the drum holder 12 and the thread drum 11, the yarn return spring 13 biases.
  • a thread supply (shown here in black) is wound on.
  • the drum holder 12 is rotatably mounted in the coil holder 6, wherein this storage is formed so that the rotation of the drum holder 12 is opposed to a counter force which is greater than the spring force of the thread return spring 13.
  • the thread return spring 13 is formed as a tension spring. Alternatively, we can of course be used torsion springs or other spring means.
  • FIGS. 4 and 6 show possible unclaimed alternatives of storage of the bobbin 4.
  • FIG. 4 is shown instead of a tension spring loaded with torsion spring solution.
  • the thread drum 12 is much thinner. This can be helpful when using thread drums 11 which are commercially available and have an inner diameter given by the trade.
  • the thread return spring 13 is here formed by two above and below the thread drum 4 arranged torsion springs.
  • the coil springs shown are only to be understood as an example, for example rubber springs can also be used here.
  • the drum holder 12 can be mounted with friction either in the thread drum 11 or on the springs of the thread return spring 13. Is also not necessary to use two springs, alternatively, a single spring can be used, in which case either no storage or a freely rotatable storage is provided on the opposite side. Another possibility is the rotatable and frictional bearing of the springs, so that the whole, in FIG. 4 shown assembly is justified against the opposing force.
  • FIG. 5 is an illustration of the right portion of the storage of the bobbin 4 on the bobbin holder 6 in an enlarged view.
  • the thread 5 is guided through a thread eye 20 in the feed arm 3.
  • the feed arm 3 is essentially a hollow cylindrical rod which is slotted in the upper region to form the thread take-up 10.
  • the bobbin holder 6 is here designed as a rectangular frame which is fastened on the one hand to the feed arm 3 and on the other hand to the bobbin 4. This is a further advantage of the invention that the thread bobbin 4 is arranged and fixed directly on the feed arm 3, while it is held in the prior art via separate components on the arm holder 2.
  • the thread return spring 13 is also formed by two springs, which are shown here by way of example as a helical spring. These are compressed by the withdrawal force when pulling on the thread 4. Again, the thread 5 passes through the thread eye 20 which is fixed to the front part of the bobbin holder 6. In this embodiment, therefore, the entire yarn package 4 is used to the feed 3.
  • the thread bobbin 4 is fixedly mounted on a feed arm 3 and that the feed arm 3 in turn is held by a spring force on the arm holder 2.
  • a spring force indirectly holds the bobbin 4 and is directed so that the withdrawal force applied to the thread 5 causes a displacement of the bobbin 4, taking into account the above-mentioned balance of power.
  • the spring means is not limited to one or two springs, if in this description of thread return spring 13 is spoken, this also means a package of successively and / or connected in series springs.
  • FIG. 9 again shows the detail "Z" FIG. 2 , Here, the transition of the outer part of the feed arm 3 is shown to the insertion tube inserted into it. To recognize here is also the slit-like thread receiving 10th
  • FIG. 10 is a sectional view of the in FIG. 9
  • This feed arm 3 has, for example, a slot-like thread take-up 10, which is closed by a thread lock 21.
  • Thread lock 21 is formed here by a flap. This flap may be formed continuously along the entire length of the feed arm 3, alternatively, only a smaller flap may be provided or a plurality of flaps may be used at some positions.
  • FIG. 11 Another unclaimed training shows FIG. 11 ,
  • the thread bobbins 4 are arranged on a common unit which is integrated in the arm holder 2.
  • the feed arms 3 are formed here as a hollow cylindrical rods and have the slot as a thread receiving 10.
  • the feed arms 3 are rotatable about an axis of rotation D relative to the arm holder 2, here, as well as in the in FIG. 1 illustrated embodiment, is designed as a hollow cylinder.
  • the rotation axis D is concentric with the center axis of the cylindrical arm holder 2.
  • FIG. 12 Details on the formation of the thread bobbins 4-bearing unit and their storage in the arm holder 2 are in FIG. 12 shown. It can be seen that the thread bobbins 4 are arranged on a common thread bobbin insert 15. This consists essentially of a shaft which is inserted into the arm holder 2 from above and rests at the bottom with an insertion limit on an inwardly projecting edge of the arm holder 2. In the upper region of the thread bobbin insert 15 is secured by a locking pin 23. On the thread bobbin insert 15 three thread bobbins 4 are here placed, which are rotatably mounted relative to the thread bobbin insert 15 on this, wherein the thread return spring 13, not shown here acts against the rotation of the bobbin 4 relative to the thread bobbin insert 15.
  • arm holding rings 14 are provided which have an exit window as a thread passage 19 on the side of the feed arms 3.
  • the feed arms 3 are attached.
  • the feed arm 3 and the Armhaltering 14 may also be formed by a common component or firmly together be connected. In the embodiment shown here, however, the feed arms 3 are provided with lateral jaws, via which they can be attached to the Armhaltering 14. This will be in conjunction with the FIGS. 13 and 14 later described in detail.
  • the Armhalteringe 14 are long the axis of rotation D slidably mounted on the arm holder 2 and are held by a return spring 16 in an upper operating position. This is because after inserting the thread bobbin insert 15 into the arm holder 2, the arm retaining rings 14 can be pulled down with one hand, so that the thread passage 19 increases to such an extent that the user can grip with two fingers into the window thus formed and the free end of the thread 5 can pull out of the arm holder 2. Since the feed arm 3 is pulled down together with the Armhaltering 14, the user draws in this way the thread 5 on the feed arm 3 and can simply insert the thread in the upper slot of the thread take-up 10. After the arm retaining ring 14 has returned to its original position, the thread 5 is then passed through the thread passage 19, so that this thread passage 19 can replace the thread eye 20.
  • the locking pin 23 serves not only to secure against pulling up, but also as a turnstile. This prevents the tensile force on the thread 5 or the force applied by the thread return spring 13 from twisting the thread bobbin insert 15 in the arm holder 2.
  • FIG. 12 illustrated unclaimed embodiment has the particular advantage that on the one hand, the entire supply of thread is hidden in the arm holder 2 is provided and on the other hand, the bobbins 4 can be offered as a replacement unit. Of course, this requires a uniform consumption of the respective threads 5.
  • FIGS. 13 and 14 the holder of the feed arms 3 is shown in detail. It can be seen here that the arm holder ring 14 has laterally protruding snap-on aids 18 (see FIG FIG. 14 ). Further, the thread passage 19 is in FIG. 14 clearly visible. Of course, the tube forming the arm holder 2 has a corresponding recess, so that the thread passage 19 is continuous.
  • the feed arm 3 has, as in FIG. 13 is shown, lateral jaws, which have pockets on their inside in the form of depressions. After the jaws are first widened when attaching to the Armhaltering 14, they then spring back again, wherein the locking aids 18 engage in the pockets and so determine the feed arm 3 positively on the arm holder 2. This has the advantage of having the connection between Armhaltering 14 and feed arm 3 can be loaded with a larger moment without the feed arm 3 would fall down.
  • FIG. 15 a modular embodiment of the yarn feeding device is shown.
  • the individual holders of the feed arms 3 are fastened to pipe sections, which in turn can be plugged onto a lower pipe section of the arm holder 2.
  • This lower tube piece is simultaneously designed to realize a height adjustment as a telescopic rod.
  • three segments are provided, so that here three feed arms 3 are implemented. Due to the modular design, the user can individually determine the number of threads 5 supplied to him.
  • the upper end is formed by a plug, which can be plugged onto the uppermost segment.
  • this plug can also be formed as a hollow tube piece that can store one or more thread bobbins 4 as a thread reel magazine 24, wherein this one thread reel magazine 24 can have two opposite, lateral slots which are so large that the user with 2 fingers each the uppermost bobbin 4 can grip and replace a consumer thread bobbin 4 on the bobbin holder 6 thereby.
