    Description: [0001] The invention relates to a spinning or twisting machine having a holder and at least one spindle bench held movably by the holder along at least one guide.
    In spinning or twisting machines required for spinning or twisting relative movement between the ring rail and spindle spindle is realized by a hubbewegbare, so an up and down movable ring rail in conjunction with a stationary spindle bank or vice versa. The hubbewegbare ring rail holds opposite the hubbewegbaren spindle bank the advantage of a lower mass. For example, a ring bank designed for 24 spindles can have a mass that is smaller by a factor of seven than an associated spindle bank. By contrast, a stroke-movable spindle bank allows a lower yarn load, a lower variation in yarn elasticity and higher productivity. However, the structural design of a movable spindle bank proves to be very complex because of the problems of higher mass as well as the drive of the rotatable spindles carried by the spindle bank. Therefore, the movable ring rail is still given preference today.
    With the document DE 19 618 260 A1 a but not pursued attempt was made to counteract the aforementioned problem with a spinning or twisting machine, which has a arranged on a spindle bank portion, mitbeweglichen engine by means of a drive belt for driving all Spindles of the spindle bank portion is provided. The associated problem of increasing the weight was remedied by forming the spindle bench section from sheet-metal profiles and compensating the dead weight of the spindle bench section compensating spring. Furthermore, for the stability of the lifting movement of the spindle bench section, a guide has been proposed consisting of a guide rail with guide rollers rolling on it. The lifting movement is carried out by a reciprocally movable drawstring, one end of which is connected to the spindle bench section via a positionally fixed deflection roller. The other end is connected to a spindle-side winding roller of a winding roller pair whose concurrent further winding roller is coupled by means of a further tension band with a drive shaft of a motor. The further winding roller has a larger diameter than the winding spindle coupled to the spindle, whereby a dependent of the diameter difference drive ratio for the lifting movement is realized. However, the spinning or twisting machine has a further complex structure with a correspondingly powerful despite compensation spring to be provided drive.
    Starting from the prior art, it is an object of the present invention to provide a spinning or twisting machine with a simplified structure and more preferably a variable drive ratio for the lifting movement of the spindle rail in order to use the benefits associated with the hubbewegbaren spindle bank.
    This object is achieved according to one aspect of the present invention by a spinning or twisting machine with the features of claim 1.
    Further advantageous embodiments of the spinning or twisting machine are the subject of the dependent device claims.
    The proposed spinning or twisting machine has a holder and at least one of the holder along at least one guide hubbewegbar held spindle bank. The holder may for example be attached to a support frame of the spinning or twisting machine. The guide can be commercially available guide systems, such as a combination of guide rod and a relative thereto by means of sliding or roller system or tooth engagement relatively movable guide carriage.
    The proposed spinning or twisting machine is characterized in that the spinning or twisting machine comprises a pulley device for lifting the at least one spindle bank. The pulley system is based on the rope-pulley-train principle. The pulley device has for this purpose alternately via at least one loose and fixed role guided tension band. The at least one loose roller is positionally variable with the spindle rail and the at least one fixed roller with the holder fixedly coupled. The drawstring extends at a stationarily attached first end of the drawstring over an equal number of fixed and loose rollers up to a positionally variable second drawstring end. In a mitbewegbaren with the spindle rail fixed first end of the drawstring, the drawstring extends over a larger number of fixed than loose wheels to the positionally variable second Zugbandende. The first drawstring end may be fastened to the spindle bench in this alternative embodiment. The stationary attachment of the first drawstring end can take place, for example, by means of a fastening to the holder, to a component carrying the at least one roller and coupled to the holder, or to another immovable, ie positionally fixed, component of the spinning or twisting machine. The attachment site is generally preferable to be selected such that a length of the drawstring is kept short and the attachment can be made simple.
    Preferably, the drawstring is selected from a material and a shape that ensure the lowest possible stretch of use. Taking into account the cost and strength aspect, the tension band is preferably formed from a wire rope. The at least one loose and / or fixed roller may have at least one partially circumferential web and more preferably a circumferential groove for guiding the tension band. Alternatively, the tension band may be configured with tension members such as a pull chain taking into account the use stretch aspect, the rollers may be circumferentially formed with engagement members for engagement with the tension members such as teeth. Further alternatively, the tension band may be formed in a toothed belt-like manner in connection with toothed rollers. An engaging operative connection between rollers and tension band allows a reduction of possible slip between these components.
    With the pulley can be achieved by the factor of a predeterminable ratio, a significant reduction in the stroke of the spindle spindle required traction by the factor of a predeterminable ratio, which depends on the number of loose and fixed roles and thus the number of standing in operative connection with these load-bearing Zugbandsträngen. This makes it possible to provide a spinning or twisting machine with a structurally simple lifting mechanism for lifting the spindle bank, whereby the advantages of a hubbewegbaren spindle bank described above can be fully utilized. Furthermore, in comparison to the prior art, a less powerful drive can be used for the pulling movement. Depending on the gear ratio could be used, for example, suitable for hubbewegbare ring gears drive. In addition, the gear ratio can be set as required by changing the number of loose and fixed roles in a predetermined manner.
    To further simplify the construction of the pulley device, the axis of rotation of the at least one loose roller and / or the at least one fixed roller is oriented transversely to the axis of movement of the spindle bank. As a result, deflections can be saved. Further preferably, the axes of rotation of the at least one loose and fixed roller are oriented parallel to each other and particularly preferably arranged in a common plane, whereby a distance between the at least one loose and fixed role is less predictable and the use of elongation thus reduced by a concomitant shorter tension band ,
    According to one embodiment, the guide of a stationary first guide member and a relatively movable and engaging with this second guide element is formed which carries the at least one loose roller and having an attachment point for the at least one spindle bank. The guide may be, for example, a guide as described above, wherein the guide carriage preferably forms the second guide element for carrying the at least one loose roller and has the fastening point because of a required smaller installation space. The second guide element can thereby be provided as a multifunctional component. The at least one loose roll is further preferably arranged in a section between the fastening point and the engagement section, which engages with the first guide element. The space available between the bracket and spindle bank space can be optimally utilized. Furthermore, compared to the spindle bank maintenance poorer pulley device can be arranged from the perspective of an operator in an area behind the spindle rail, whereby the spindle bank without disturbing influences by components and Zugbandstränge the pulley device remains freely manageable.
    According to one embodiment, the holder has a mounting bracket for the at least one fixed roller, wherein the mounting bracket has an attachment point for a ring rail, which is assigned at least the spindle bank. The at least one fixed roller is further preferably arranged in a section between the fastening point and the holder. In addition to the optimized utilization of the available space, the pulley device can be arranged without interfering with the position and function of the spindle bank and ring rail. Furthermore, the ring rail and the spindle bank can be optimally positioned to each other for the required relative movement by means of the attachment point or attachment points.
    Preferably, the pulley is a factor pulley with multiple fixed and / or loose rollers, each along a common axis of rotation, in particular interchangeable, are arranged. Such a pulley is designed particularly simple. The gear ratio of such a pulley type can be an even number of at least 1: 2 in position-solid coupling of the first Zugbandendes with the holder in combination with an equal number of loose and fixed roles. In contrast, in the case of positionally variable coupling with the spindle bench in combination with a larger number of fixed rollers than on loose rollers, an odd-numbered transmission ratio of at least 1: 3 can be provided. The choice of attachment of the first drawstring end thus allows a variably adjustable transmission ratio, which is freely selectable depending on the mass of the spindle bank by arranging a corresponding number of loose and fixed roles. Thus, a structurally simple ausgestalteter lifting mechanism can be realized with a gear ratio that is customizable as needed.
    In addition, the arrangements of the fixed rollers along a common axis of rotation and the loose rollers along a common axis of rotation allow an extremely compact arrangement of the respective rollers and thus a compact design of the pulley device. Furthermore, worn rollers can be replaced without considerable effort.
    Further preferably, a pulley device is arranged in each case in a range from a longitudinal end to a longitudinal center of the spindle rail. Particularly preferably, in each case a pulley device is arranged on a longitudinal end of the spindle rail. A stroke movement of the spindle bank can thereby be stabilized. Further, the weight force of the spindle force can be further divided, whereby the existing of the pulley mechanisms lifting mechanism undergoes a lower load, which has a favorable effect on their durability.
    Particularly preferably, in this embodiment, the respective second Zugbandende removably attacks on a common traction means stationary, which is mounted translationally movable. Preferably, the respective point of attack on the common traction means is variably adjustable. The drawstring can be provided interchangeable. Furthermore, identically configured pulley devices can be provided for the spinning or twisting machine, whereby costs can be reduced.
    The common traction means is further preferably translationally movable along a longitudinal axis of the spindle spindle, wherein at least one of the drawstrings is deflected over a arranged in its Zugbandweg between the at least one fixed roller and associated point of deflection pulley. As a result, the available space in the direction of the longitudinal extension axis of the spindle bank can be optimally utilized. Furthermore, the common traction means, at least in the region of such a spindle bank, which is arranged adjacent to a drive for the traction means, shorter and thus easier to be designed. Preferably, a drive belt extends from the drive to a coupling point with the common traction means, wherein the drive and the drive belt are designed to pull the common traction means in a direction which is directed against the weight of the spindle spindle acting on the pulley. For example, the drive may be an electric motor with a drive wheel for winding and unwinding the drive belt. The drive belt may be a finite drive belt. The drive of the drive pulley in the winding direction thereby further preferably causes an upward movement of the spindle rail, whereas the drive in the rolling direction leads to a downward movement of the spindle bank by the weight force counteracting traction. The drive is preferably coupled to a central control unit of the spinning or twisting machine, which controls the drive as needed.
    The common traction means is preferably designed by a pull rod, which experiences a negligible extension of use over its life and has a high stability. Further, the pull rod may have a plurality of points of attack for a respective second Zugbandende, whereby a plurality of pulley devices can be operated by means of the common traction device equal movement. The pull rod further preferably extends over at least two adjacent spindle banks, which are each movable up and down with pulley devices, the second pull band ends of these pulley devices engaging the common traction means. Thus, at the same time an identical stroke movement for the at least two spindle banks can be realized.
    Further preferably, the second Zugbandende engages fixed depending on the number of loose and fixed rollers on the common traction means that an end position of the second Zugbandendes that corresponds to an upward end position of the spindle, within a range associated with the spindle bank Section is located. This can ensure that the second Zugbandende remains in any position of the spindle bank in the region of the associated spindle bank or section. This favors the complete and easy accessibility of the drawstring regardless of a position of the spindle bank. A section usually corresponds in the machine longitudinal direction of the spinning or twisting machine to a section, which is assigned a spindle bank with several spindles per machine side. The individual sections can be operated via a central control unit, in particular autonomously.
    According to a further aspect of the present invention, the above object is achieved by a method having the features of claim 10.
    The method is executable on a spinning or twisting machine according to one of the embodiments described above and comprises a step of Hubbewegens the spindle bank by means of at least one pulley device, which may preferably have a configuration according to one of the embodiments described above.
    Further features and advantages of the invention will become apparent from the following description of preferred embodiments of the invention, with reference to the figures and drawings showing essential to the invention details, and from the claims. The individual features may be implemented individually for themselves or for several in any combination in a preferred embodiment of the invention.
    Preferred embodiments of the invention will be explained in more detail with reference to the accompanying drawings.

    In the following description of preferred embodiments of the present invention, the same or similar reference numerals are used for the elements shown in the various figures and similarly acting, with a repeated description of these elements is omitted.
    Fig. 1 shows a perspective side view of a pulley device 10, which is coupled to a longitudinal left end 2 of a spindle bank 1 of a spinning or twisting machine according to an embodiment. The pulley device 10 is based on the rope-pulley-train principle and is designed in this embodiment as a factor pulley. The pulley device 10 comprises four loose rollers 12 and five fixed rollers 14, each having a groove for guiding a wire rope 16 as a drawstring. The loose 12 and fixed rollers 14 are each arranged along a common axis of rotation 18a, 18b strung together. The axes of rotation 18a, 18b are parallel to each other and lie in a common plane. The respective common axis of rotation 18a, 18b is formed by a rod element, wherein the fixed roller 14 rotatably supporting rod member 18a is held by a support bracket 20 which surrounds the fixed rollers 14 like a frame circumferentially. The support attachment 20 is fixed in a fixed position to a holder 9 of the spinning or twisting machine in a region of an upper end of a guide rod 32 of a movement of the spindle rail 1 leading guide 30. In the holder 9 is in this preferred embodiment, a support frame of the spinning or twisting machine or a supporting element of the spinning or twisting machine, which is stationarily positioned.
    The loose rollers 12 rotatably supporting rod member 18b is held by one of the guide 30 associated guide carriage 34 on its fixed rollers 14 facing top 34a. The guide carriage 34 has a guide rod 32 engaging around the guide portion 36 which is movable along the guide rod 32. Further, the guide carriage 34 includes a plurality of threaded holes 40 for receiving a threaded shaft of a screw 42 on an end face 34b adjacent to the upper side 34a. By means of the available threaded holes 40 and associated threaded screws 42, the longitudinal left end 2 of the spindle head 1 and a first end 16a are provided of the wire rope 16 at the end face 34b attached to the guide carriage 34 mitbewegbar. The first wire end 16a is fixed in a clamping manner in connection with a washer 44 for enlarging a clamping surface on the end face 34b. The first wire end 16a is thereby coupled to the positionally variable spindle bank 1, whereby the wire end 16a, in conjunction with the four loose 12 and five fixed rollers 14, is subdivided into nine load-bearing wire sections 16c. As a result, the tensile force is reduced by a factor of 9 in view of the weight force exerted by the mass carried by the bottle device 10.
    The second wire end 16b is fixed by means of a clamp 26 to a pull rod 24 which is movable in translation on a bearing roller 28 in the longitudinal axis direction of the spindle head 1. By moving the pull rod 24, the clamp 26 and thus the second wire end 16 b is moved, whereby it comes to a lifting movement of the spindle rail 1.
    According to an embodiment not shown, the first end of the wire rope is fixed in the fixed position in the fixed rollers, wherein the wire rope is guided by an equal number of four loose and fixed roles. As a result, a transmission ratio of 1: 8 can be realized. A change in the fixed and loose roles by an equal number reduces or increases the gear ratio accordingly by an even multiple.
    The spindle bank 1 has a plurality of passages for the respective mounting of a spindle 4. The spindles 4 are driven synchronously in the usual manner by means of an endless tangential belt 6, which is coupled to an electric motor 5. The electric motor 5 is movably connected to the spindle bank 1 or is supported by it, as shown by way of example in FIG. 2.
    Fig. 2 shows a front perspective view of a spindle bank section of a spinning or twisting machine with end arranged Flaschenzugeinrichtungen 10 according to an embodiment. The spindle-bank section is a spindle-bank section arranged last in the machine longitudinal direction of the spinning or twisting machine. The spindle bank section has a spindle bank 1 with an electric motor 5 arranged thereon, wherein the spindle bank 1 carries twenty-four spindles 4, which are driven by the electric motor 5 by means of a drive belt 6.
    The arranged on the left-side end of the spindle section press pulley 10 is coupled to a longitudinal right end 3 of a spindle bank 1 and a longitudinal left end 2 of an adjacent another spindle 1 of an adjacent spindle spindle section via a similar guide 30 as described above. The pulley device 10 is constructed identically to the one described above. On the guide carriage 34 of the further guide 30, unlike the one described above, the longitudinal right end 3 of the spindle bank 1 and the adjacent longitudinal left end 2 of the further spindle bank 1 are fastened via the available threaded bores 40. The first wire end 16a is fixed in a clamping manner by means of a threaded screw which secures the longitudinal right end 3.
    The arranged on the right-hand end of the spindle section press pulley device 10 is coupled to a longitudinal right end 3 of the spindle head 1 via a similar guide 30 as described above. The second wire end 16b of this pulley device 10 is connected via a deflection roller 22 for deflecting the wire
