Definitions
- the invention relates to a Fadenchangier adopted for a winding device of a cheese-producing textile machine according to the preamble of claim 1, as known from DE 2 028 151 A is known.
- thread-guiding drums It is widely used, for example, in winding machines, which operate at relatively high winding speeds, as thread-changing devices so-called thread-guiding drums.
- thread guide drums have a groove for traversing the thread and at the same time drive the textile spool frictionally.
- a cross-wound textile machine is described with a Fadenchangier observed in which the yarn guide is driven by a reciprocating drum. Since such sweeping thread gears are usually lubricated with oil or grease, the reciprocating drum is surrounded in each case with a bung thread housing.
- the housing has a slot through which the driver or the shuttle of the thread guide protrudes into the groove of the reciprocating drum.
- the thread guide slot of the broom thread housing is sealed by means of a cover connected to the thread guide, which is also referred to as a sealing lip. This seal prevents oil or grease from escaping from the slot or textile dust entering the slot.
- Kehrgewindegetriebe A major disadvantage of this Kehrgewindegetriebe, however, is that also Kehrgewindetrommeln in the production are relatively expensive and also require a considerable maintenance.
- Such a device also has fundamental disadvantages of reverse-thread drives, namely that such drives are relatively loud in operation and that the traversing speeds which can be achieved with such devices are relatively small.
- a Fadenchangier driving is described with a yarn guide, which is guided in the field of work on a yarn guide rod and is driven by an endless drive means of a single drive.
- the single drive is designed as a microprocessor-controlled stepper motor.
- the present invention seeks to develop a Fadenchangier adopted for the winding devices of cheese-producing textile machines, in particular, the necessary for proper operation of the Fadenchangier overlooked cleaning effort can be minimized.
- the embodiment of the invention has the particular advantage that can be ensured by such training in a simple manner that the arranged in the interior of the Fadenchangierü, dirt-sensitive components are protected from textile dust and thus spared from contamination even after prolonged use. Since the sealing of the interior is carried out directly by the endless draw means for the thread guide, in addition no additional components are necessary, which allows a cost-effective construction of the device.
- the endless traction means is guided over deflecting wheels, which are positioned laterally next to the traversing region at a short distance from the front wall sections of the housing of the thread traversing unit such that the Endloszugstoff slides in the area between the guide wheels with its outer side along the wall portions of the housing along and thereby forms a seal.
- deflecting wheels which are positioned laterally next to the traversing region at a short distance from the front wall sections of the housing of the thread traversing unit such that the Endloszugstoff slides in the area between the guide wheels with its outer side along the wall portions of the housing along and thereby forms a seal.
- the yarn guide which is preferably made of a wear-resistant oxide ceramic (Anspr.6), is arranged on a special guide shoe, which in turn is slidably guided on a guide rod and fixed to Endloszugstoff. Since the guide rod is completely behind the seal formed by the endless traction means and the Wandungsabitese, there is the possibility to grease the guide rod sufficiently without the risk that this guide is immediately contaminated by dirt particles.
- a wear-resistant oxide ceramic As set forth in claim 3, it is also advantageously provided that the yarn guide, which is preferably made of a wear-resistant oxide ceramic (Anspr.6), is arranged on a special guide shoe, which in turn is slidably guided on a guide rod and fixed to Endloszugstoff.
- the single-motor drive is preferably designed as a stepper motor and connected via a control line to an example central control computer. This means, by specifying appropriate working cuts, the single motor drive purely software, and thus in a relatively simple manner, controlled and eg the traversing width or the traversing speed of the thread guide set and changed anytime easily if necessary.
- the endless traction means is formed in a preferred embodiment as a toothed belt. Since such a toothed belt is driven positively, is ensured with such an embodiment that each defined control of the stepping motor both in terms of the traversing range, the traversing width or the traversing speed, exactly, that are implemented without slippage. In addition, it is ensured that the set traversing range or the specified traversing width can not be adjusted automatically during operation.
- the Fadenchangier listening invention is designed as a thread guide unit in the form of a modular component that can be easily changed completely if necessary. That is, the FadenchangierINA the winding device can be easily installed and removed if necessary after loosening a few screws fixing.
- FIG. 1 is one half of a cross-wound producing textile machine, in the present embodiment of an open-end rotor spinning machine, shown and designated 1.
- Such per se known open-end rotor spinning machines have a plurality of jobs 2, which are each equipped with a spinning box 3 and a winding device 4.
- the spin box 3 the sliver 6 presented in a sliver can 5 is spun into a thread 7, which is then wound on the winding devices 4 to form a cross-wound bobbin 8.
- the winding device 4 for this purpose has a creel 9 for rotatably supporting the cheese 8, a winding drum 10 for driving the cheese and a Fadenchangier worn 11th
- the winding drum 10 is driven via an electric motor single drive 21.
- Such open-end spinning machines 1 generally further comprise a cross-bobbin transport device 12 for disposing finished cross-wound bobbins 8.
- a service unit 16 such as a cheese changer or a piecing arranged on or on the spinning machine 1 is also, on guide rails 13, 14 and a support rail 15 movable, a service unit 16, such as a cheese changer or a piecing arranged.
- the drive 17 of this service unit 16 has rollers 18 and a support wheel 19.
- the supply of the service unit 16 with electrical energy via a drag chain or, as indicated, via a sliding contact device 20th
- Such service units 16 are, as is known, movable along the workstations 2 of the open-end spinning machine 1 and engage automatically when there is a need for action at one of the workstations 2.
- Such a need for action exists, for example, if at one of the jobs 2 a yarn breakage has occurred or if at one of the jobs the cheese has reached its prescribed diameter and must be replaced with an empty tube.
- Fig. 2 and 3 is the Fadenchangier wornen 11 of the invention, as it is arranged in each case in the field of winding device 4 of the numerous jobs 2 of the textile machine 1, shown in detail.
- the Fig. 2 shows a perspective view of a compact yarn guide unit 22 formed, closed Fadenchangier Anlagenen 11th That is, the interior 37 of the housing 23 of the thread guide unit 22 is covered with a cover member 24 and thus protected against the ingress of textile dust and fiber fly.
- the Fig. 3 shows the same thread guide unit 22 in a similar perspective view, but without the cover member 24, that is, looking into the interior 37, in which the toothed belt transmission and the guide for the yarn guide are arranged.
- the yarn guide 25 which, as usual, is made of an abrasion-resistant material, preferably a Oxydkeramik, fixed to a guide shoe 26, which in turn is slidably guided on a guide rod 27.
- the guide rod 27 is in turn set in the side walls 28, 29 of the thread guide unit 22.
- the guide shoe 26 is also attached to the outside 40 of a continuous drawing means, preferably a toothed belt 30.
- the toothed belt 30 is guided in the illustrated embodiment at least via deflection wheels 31, 32 and a drive wheel 33.
- the drive wheel 33 is rotatably mounted on the motor shaft of an electric motor, reversible drive, preferably a stepper motor 34, which is connected via a control line 36 to a control computer 35, for example, a central computer of the textile machine and can be controlled via this defined.
- a control computer 35 for example, a central computer of the textile machine and can be controlled via this defined.
- a section computer or a separate workstation computer can of course also be used as the control computer 35.
- the deflection wheels 31, 32 arranged laterally next to the traversing region B of the yarn guide 25 are positioned so that the toothed belt 30 constantly bears with its outer side 40 against the wall sections 38, 39 of the housing 23 or slides along them.
- the toothed belt 30 forms in the traversing region B of the yarn guide 25 in conjunction with the Wandungsabitesen 38, 39 a seal that reliably prevents the ingress of textile dust and / or fiber fly into the interior 37 of the yarn guide unit 22 during operation at any time.
