    The invention relates to a yarn splicing device for a cheese-producing textile machine according to the preamble of claim 1.
    Such Fadenspleissvorrichtungen are known in the textile industry, especially in connection with cheese winder, for a long time.
    Such proven in practice thread splicing devices, which usually have a pneumatically acted splice prism, a lower and an upper thread clamping and cutting device for fixing and cutting to be spliced yarn ends and a yarn feeder for positioning the prepared yarn ends in the splice of the splicing prism have been relatively extensively described in numerous patent applications, for example in DE 19 510 171 A1 or DE 10 2006 006 390 A1.
    With such Fadenspleissvorrichtungen two yarn ends that have arisen after a yarn break or a controlled cleaner cut, be pneumatically swirled into a knot-free connection, which has almost yarn strength and ideally has a nearly yarn-like appearance.
    When thread splicing devices, as they are known from DE 19 510 171 A1, the drive of the various functional elements of the yarn splicing device, that is the Fadenklemm- and cutting devices, the cover element of the splicer and the Fadenzubringers via a cam plate, via a plug-in coupling connected to a spool own drive.
    In DE 10 2006 006 390 A1 thread splicing devices are described which have within their splicer housing a pivotally mounted control segment with an external toothing and equipped with a drive pinion, defined controllable stepper motor.
    To the drivable control segment are directly or indirectly connected to the various functional elements of the yarn splice device. This means that the control segment has, for example, in the region of its circumference, a ball joint connection to which the thread feeder is connected via a control linkage. In addition, the control segment is connected via a special lever mechanism with the thread clamping and cutting devices and a cover element of the yarn splicing device.
    In the yarn splicing devices described above, the thread clamping and cutting devices are also in each case fixable in different positions on the splicer housing. That is, by means of appropriately trained holding devices, the thread clamping and cutting devices can be screwed to the splicer housing, that the thread ends, depending on the positions of the thread clamping and cutting devices, which in turn are oriented on the yarn to be spliced, have a different length.
    With regard to the length of the thread ends can be distinguished between a standard, a Elastogarn- and a compact yarn setting.
    However, the known Fadenspleissvorrichtungen have the disadvantage that, since only between three length settings can be selected in problematic yarns often an exact adjustment of the length of the thread ends is not possible.
    In the known Fadenspleissvorrichtungen any change in the length adjustment is associated with a considerable, time-consuming work, the work can also be performed only when stationary textile machine.
    Based on the aforementioned prior art, the present invention seeks to provide a yarn splicer, the thread clamping and cutting devices are mounted so that at any time a fast, easy and optimal adjustment of the length of the intended for a splice thread ends is possible.
    This object is achieved according to the invention by a yarn splicing device as described in claim 1.
    Advantageous embodiments of the invention are the subject of the dependent claims.
    The inventive design of a yarn splicing device has the particular advantage that due to the possibility of an almost stepless adjustment of the distance between the thread clamping and cutting devices an optimal adjustment of the length of the yarn ends to be spliced is possible.
    With the thread splicer according to the invention can thus be ensured in a simple manner that the yarn ends to be spliced always have an optimally adapted to the respective yarn material, advantageous length. The thread ends cut to length with a thread splicing device according to the invention enable the reliable production of thread splices, which always correspond to a required quality standard.
    As described in claim 2, it is further provided in an advantageous embodiment that the lower and the upper thread clamping and cutting device is separately positionable by means of an actuator.
    Such a design makes it possible, especially in problematic yarns, to respond very specifically and very sensitively, that is, if necessary, for example, the lower thread clamping and cutting device with respect to the splicing prism have a different distance than the upper thread clamping and cutting device.
    In this way, thread splices can be created with thread ends having different lengths. The thread end of the lower thread can for example be cut slightly longer than the thread end of the upper thread, if necessary, however, a thread end of an upper thread can be created, which has a greater length than the associated thread end of the lower thread.
    According to claim 3 is provided in an advantageous embodiment that a worm gear is part of the actuator for a thread clamping and cutting device. Such a worm gear has, inter alia, the advantage that in a relatively small space, a large gear ratio can be realized, which allows a very accurate adjustment of the position of the thread clamping and cutting device.
    In addition, such worm gear with large gear ratios are self-locking, so that can be dispensed with in connection with the actuators on an additional locking device.
    In connection with the actuator for a thread clamping and cutting device but not necessarily worm gear must be used, there are quite other types of transmissions conceivable.
    As described in claim 4, in an alternative embodiment, for example, be provided that an eccentric gear is part of a control gear for a thread clamping and cutting device. Such an eccentric gear, for example, is very inexpensive and also relatively insensitive to contamination.
    As described in claims 5 and 6, it is provided in further advantageous embodiments that the actuators for the thread clamping and cutting devices are either manually operable (claim 5) or via the central control device of the cheese winder respectively mechanically driven (claim 6 ).
    A manual operation (claim 5) in particular has the advantage of relatively low production costs, however, has the disadvantage that the operator to operate the actuators always come to the relevant job and there has to lend a hand, which is relatively cumbersome and time consuming is.
    Fadenklemm- and cutting devices whose actuators, as described in claim 6, on the central control device of the cheese winding machines are each mechanically adjustable, in contrast, have the advantage that, for example, in a batch change, a fast, central adjustment of the numerous Fadenspleissvorrichtungen one Spinning machines is possible. This means that the length of the thread ends to be spliced can be easily and exactly adjusted according to the new yarn material.
    If the actuators of the thread clamping and cutting devices, as described in claim 6, each mechanically controllable, it is advantageous to provide an electromotive drive for positioning each of the thread clamping and cutting devices each have a defined controllable stepper motor (claim 7).
    Such a stepping motor allows a simple way at any time an accurate and reproducible positioning of the thread clamping and cutting devices.
    The invention will be explained in more detail with reference to an embodiment shown in the drawings.
    Show:<Tb> FIG. 1 <SEP> in side view a workstation of a cheese winder, which is equipped with a thread splicing device according to the invention,<Tb> FIG. 2 <SEP> in perspective view a yarn splicing device with continuously adjustable upper and lower thread clamping and cutting devices during the insertion of the yarn ends to be spliced,<Tb> FIG. 3 <SEP> the thread splicing device according to FIG. 2 in side view.
    In Fig. 1 is a schematic side view of a generally designated by the reference numeral 1 cheesemakers producing textile machine, in the embodiment, a cheese winding machine, shown.
    As is known, have such automatic packages 1 between their (not shown) Endgestellen a variety of similar jobs, in this case winding units 2, on. On these winding units 2 spin cops 9, which were produced for example on a (not shown) ring spinning machine, rewound to large-volume cheeses 15, which are transferred after their completion on a machine-length cross-coil transport device 21.
    In the exemplary embodiment, the cross-winding machine 1, a machine-own logistics facility in the form of a cop and sleeve transport system 3, of which in Fig. 1, only the Kopszuführstrecke 4, the reversibly driven storage section 5, one of the leading to the winding units 2 transverse transport sections 6 and the Sleeve return path 7 are shown.
    In this cop and sleeve transport system 3 run, positioned on transport plates 8 in a vertical orientation, spinning cops 9 or empty tubes to.
    The supplied spinning cops 9 are rewound in the unwinding position AS, which is located in each case in the region of the transverse transport sections 6 at the winding units 2, to large-volume cheeses 15.
    The individual winding units 2 have for this purpose, as is well known and therefore only hinted at various facilities that ensure proper operation of these jobs 2.
    These devices are known per se, for example, a winding station computer 29, which is connected via a bus line 42 to the central control device 43 of the automatic winder 1, a movable about a pivot axis 16, unterdruckbeaufschlagbare suction nozzle 12, a about a pivot axis 13 movable, unterdruckbeaufschlagbares gripper tube eleventh and a pneumatic thread splicer 10.
    The pneumatic yarn splicing device 10 is arranged slightly set back with respect to the regular yarn path and fixed, for example, with its central housing 31 on the winding unit housing 33.
    Such Fadenspleissvorrichtungen 10 have, as will be explained in more detail below with reference to FIGS. 2 and 3, in addition to a splicing prism 32 with a pneumatically actuable splice still via an upper 23B and a lower 23A thread clamping and cutting device, a pivotally mounted Fadenzubringer 26 and via a likewise pivotally mounted cover element 25, which closes the splice channel of the splicing prism 32 during the splicing process.
    As shown in FIGS. 2 and 3, the splicing prism 32 is arranged on a manifold block 46, in the holding and Auflöseröhrchen 47 are also embedded.
    The cheese 15 is freely rotatably held in the bobbin frame 28 of a winding device 24 during the winding process and is in the embodiment with its surface on a Nuttrommel 14, which carries the cheese 15 via frictional engagement and also for proper traversing of the cheese 15 running thread.
    Fig. 1 shows a situation as it results, for example, after a yarn break at a job 2. The suction nozzle 12 has received the accumulated after the yarn breakage on the cheese 15 upper thread 17o and threads the upper thread 17o straight into the Fadenspleissvorrichtung 10 a. At the same time or somewhat laterally, the gripper tube 11 fetches the bobbin thread 17u kept ready in a thread tensioner (not shown in detail) and subsequently threads it into the thread splicing device 10 as well.
    FIGS. 2 and 3 each show one of the thread splicing devices 10 according to the invention in detail.
    As described for example in DE 10 2006 006 390 A1 relatively detailed, in these known Fadenspleissvorrichtungen 10 within the central housing 31, an electric motor single drive, preferably a stepper motor, arranged, the drive pinion meshes with the external teeth of a control segment.
    The control segment is in turn connected via various lever mechanisms with the thread clamping and cutting devices 23A, 23B, the pivotally mounted yarn feeder 26 and also pivotally mounted lid member 25.
    As can be seen in particular from FIG. 2, a distributor block 46 is fixed on the splicer housing 31, which carries a defined splitting prism 32 which can be acted upon pneumatically. The distributor block 46 is also provided with so-called dissolving and holding tubes 47, in which the cut-to-length yarn ends of the upper thread 17o and the lower thread 17u are prepared for the subsequent splicing process.
    As schematically illustrated in FIGS. 2 and 3, the yarn splicing apparatus 10 further comprises actuators 18, 19 which allow continuous adjustment of the thread clamping and cutting devices 23A and 23B respectively between an outer 35 and an inner 36 limit position ,
    That is, by appropriate driving of the actuators 18, 19, the distance a between the thread clamping and cutting devices 23A, 23B amaxvariiert between a distance aminund a distance and thus the length of the cut yarn ends of upper and lower thread are set almost infinitely , The actuators 18, 19 can have different embodiments. The actuators 18, 19 may be formed, for example, as a worm gear and be operated either manually or mechanically.
    In a machine operation, the worm gear is controlled, for example, defined by a stepper motor, which is connected via the winding station computer 29, for example, with the central control device 43 of the automatic winder 1. However, instead of a worm gear, another drive device, for example an eccentric gear or the like, may be used.
    An eccentric gear can either be operated manually by the operator or, as explained above, be controlled by machine.
    Function of the thread splicing device according to the invention
    Before a batch start, first, depending on the particular yarn material present, the thread clamping and cutting devices 23A, 23B of the yarn splicing devices 10 of the automatic cheese 1 are optimally adjusted. That is, via the central control device 43 of the automatic winder 1, the actuators 18, 19 of the thread splicing devices 10 are driven so that the cut end of the upper thread 17o and the cut end of the lower thread 17u each have a predetermined length.
    If then during the winding process at one of the winding units 2 of the automatic cheese 1 a yarn break occurred or if a controlled cleaner cut was carried out due to a thread error, the cheese concerned 15 is first braked to a standstill.
    The suction nozzle 12 then fetches the upper thread 17o from the cheese 15 and threads it, for example by means of a baffle in the thread clamping device of the upper thread clamping and cutting device 23B, the splice in splice prism 32 and in the thread cutting device of the lower Fadenklemm- and Cutting device 23A.
    At the same time or almost simultaneously, the lower thread 17u is also brought in by the gripper tube 11 and likewise with the aid of a thread guide plate in the thread clamping device of the lower thread clamping and cutting device 23A, the splice channel in the splicing prism 32 and in the thread cutting device of the upper thread clamping and cutting device 23B positioned.
    Subsequently, the thread splicing device 10 is controlled via the winding station computer 29. That is, the arranged in the splicer housing 31 stepper motor begins to pivot the control segment so that the lid member 25, the thread clamping and cutting devices 23A, 23B and the yarn feeder 26 are actuated, with the result that after a short time first the lid member 25 on the Splice prism 32 attached and the splice channel is covered.
    The weiterschwenkende control segment actuated simultaneously or shortly thereafter also the thread clamping and cutting devices 23A, 23B, which clamp the thread ends of the upper thread 17o and the lower thread 17u and cut to length.
    Then the stepping motor and thus the control segment is stopped briefly, and arranged in the manifold block 46 of the splicing prism 32 holding and Auflöseröhrchen 47 are pressurized with compressed air so that the thread ends 17o, 17u sucked into the holding and Auflöseröhrchen 47 and there be largely freed from their rotation.
    Subsequently, the control segment is further pivoted by the stepper motor and thereby actuates the thread feeder 26 via a control linkage, which pulls the prepared yarn ends of upper and lower thread 17o, 17u from the holding and Auflöseröhrchen 47 and splice channel of the splice prism 32 with predeterminable overlap positioned.
    That is, the yarn feeder 26, the arms of each on the associated holding and Auflöseröhrchen 47 opposite side so in the yarn strand of upper thread 17o or lower thread 17u grasp that a thread loop is formed, via the control segment or the stepping motor so controlled that the thread ends are pulled out of the holding and Auflöseröhrchen 47 in the direction of the splice channel of the splicing prism 32. The yarn feeder 26 is thereby pivoted into a desired angular position in which it is ensured that the thread ends withdrawn into the splicing channel have a predetermined, optimum overlap.
    Also, the desired angular position of the yarn feeder 26 can, preferably before the start of a party start, at the central control unit 43 of the cheese winder 1, which are connected via a bus system 42 to the winding stations 29 of the numerous jobs 2, are set.
    When the yarn ends have reached this optimum coverage, which depends on different yarn parameters, for example on the yarn material or the yarn count, that is, when the yarn feeder 26 is positioned at a predetermined desired angular position, splicing air is directed through the cover element 25 is given a closed splice channel of the splicing prism 32 and the thread ends positioned within the splice channel are pneumatically swirled. Subsequently, the control segment is swung back by the stepper motor back to its original position.
    The control segment thereby opens the thread clamping and cutting devices 23A, 23B and the lid member 25, so that the pneumatically connected thread 17 is released. In addition, while the yarn feeder 26 is pivoted into its zero position. Afterwards, the winding process at the relevant workstation 2 can be restarted.
