    The invention relates to a gear unit of a combing machine for spinning preparation according to the preamble of claim 1. In particular, the invention relates to a gear unit comprising a main drive shaft which can be driven via a main drive wheel by means of a drive motor, a pincer shaft which is connected to a main drive wheel Crank rocker can be set in an oscillating back and forth rotary movement, a coupling rocker and an eccentric bushing, the coupling rocker being rotatably mounted on the eccentric bushing, and the coupling rocker being connected to the pincer shaft at a first connection point, in such a way that the coupling rocker oscillates from the pincer shaft is rotatable, and wherein the gear unit furthermore has a tear-off cylinder gear which is set up to drive at least one tear-off cylinder, and wherein the tear-off cylinder gear can be continuously driven via the main drive shaft and wherein an oscillating movement can be introduced into the tear-off cylinder gear by means of the coupling rocker, which movement can be superimposed on the continuous drive by means of the main drive shaft in the tear-off cylinder gear. The invention also relates to a combing machine with a gear unit as described above.
    From DE 10 2012 011 030 A1, for example, a gear unit for a combing machine for spinning preparation is known, and the gear unit has as essential structural components a main drive shaft that drives a pincer gear, the pincer gear for driving a tong apparatus with a pair of upper tongs and serves with a pair of pliers. Furthermore, the gear unit has a tear-off cylinder gear for driving two tear-off cylinders, which form respective pairs of cylinders with counter-tear cylinders, between which the fiber product to be combed is guided, the tear-off cylinder gear regularly being designed as a planetary gear in a manner known per se.
    The main challenge in the design of such a gear unit is the generation of a so-called pilgrim step movement for the tear-off cylinder of the combing machine. For this purpose, the planetary gear is initially driven with a continuous rotary movement via the main drive shaft. This continuous drive movement is superimposed with a further oscillating movement, which is also introduced into the tear-off cylinder gear by means of a push-joint rod unit, for example via a further component of the planetary gear such as the sun gear, whereby the pilgrim step movement can be generated at a gear output of the planetary gear, which is initiated in the tear-off cylinder will.
    The push-joint rod unit in turn is driven via the coupling rocker, which in turn performs an oscillating movement. The oscillating movement of the coupling rocker is incorporated into it by means of a connection to a pincer shaft of the pincer gear, the oscillating coupling rocker being accommodated on an eccentric bushing which is rotatably accommodated on the main drive shaft.
    The pincer shaft is set in an oscillating back and forth movement by means of a crank arm, the crank arm being connected to the main drive wheel with this rotating, and the main drive wheel is drivingly connected to the main drive shaft, which is ultimately driven by the drive motor.
    The gear unit is usually designed so that the sub-gear such as the tear-off cylinder gear and the gear part for moving at least the upper tongs of the tong apparatus and the rotary movement of the circular comb roller in their phase positions are rigidly connected so that, for example, an adjustment of the phase position in the pilgrim step movement is not Can be adjusted without tool intervention relative to the phase position of the tong apparatus and / or the circular comb roller. For this purpose, an operator usually has to intervene directly in the transmission with a tool.
    Accordingly, the invention is based on the object of developing a spinning preparation machine in such a way that the formation of disadvantageous fiber accumulations or the like is effectively prevented in an area adjacent to the doctor roller.
    The object of the invention is to develop a gear unit of a combing machine for spinning preparation, the aim being to create the possibility in a simple manner to adjust the phase position of the pilgrim step movement relative to the phase position of the pincer gear and / or to the phase position of the circular comb roller. Another object of the invention is to create a combing machine with a gear unit which has been improved in this way.
    This object is achieved based on a gear unit according to the preamble of claim 1 and based on a combing machine according to claim 11 with the respective characterizing features. Advantageous further developments of the invention are given in the dependent claims.
    The invention includes the technical teaching that a servomotor is provided which is arranged operatively connected to the eccentric bushing and with which a rotary movement can be introduced into the eccentric bushing.
    The core idea of the invention is the development of the transmission with an externally electrically operated servomotor in such a way that a fitter no longer has to intervene manually or with a tool in the gear unit to adjust the phase position of the tear-off cylinder gear relative to the phase position of the tong apparatus or to the phase position to adjust the circular comb roller.
    With the inventive arrangement of a servomotor in conjunction with the eccentric bushing targeted control of the eccentric bushing in its rotational movement is possible, which has an impact on the phase position or angular position of the movement of the coupling rocker that is applied to the eccentric bushing.
    If the eccentric bushing is set in rotary motion with the servomotor, the phase position of the rotary motion can be adjusted via the servomotor. The phase position or angular position of the rotary movement of the eccentric bushing affects the phase position or the movement sequence of the coupling rocker, which ultimately has a corresponding effect on the periodic, oscillating movement introduced into the tear-off cylinder gear. The result is a shift in the phase position of the pilgrim step movement in the tear-off cylinders relative to the phase position of the main drive shaft, and in this respect also relative to the phase position of the oscillating movement of the tong shaft and finally the rotary movement of the circular comb roller.
    Advantageously, the coupling rocker has a central receiving opening in which the eccentric bushing is introduced, and wherein the coupling rocker is rotatably mounted on the eccentric bushing. The eccentric bushing to the main drive wheel is set up free of a torque-transmitting connection. In this respect, the eccentric bushing is no longer forcibly moved by the rotation of the main drive wheel, which is rigidly connected to the main drive shaft. In particular, a coupling rod known from the prior art, which extends between the eccentric bushing and the main drive wheel, is omitted. In particular, an eccentric in the eccentric bushing can also be omitted. In particular, the main drive wheel only serves to couple a crank arm with which the oscillating movement is generated in the pincer shaft. The remaining function of the main drive wheel is the coupling to the main drive motor for driving the gear unit via a main drive shaft.
    The main drive shaft is in particular rigidly connected to the main drive wheel, so that the drive power of the main drive motor is introduced into the main drive shaft. The eccentric bushing is arranged in such a way that the main drive shaft extends through the eccentric bushing, the main drive shaft still being connected to a circular comb shaft for driving a circular comb roller.
    According to a possible further embodiment of the invention, a gear connection is set up between the eccentric bushing and the servomotor. For example, the transmission connection comprises a gear stage or a belt drive. According to a further embodiment of the arrangement of the servomotor with the eccentric bushing, there is also the possibility that the servomotor with the eccentric bushing is designed as a unit and / or that the eccentric bushing forms a structural part of the servomotor. For example, the eccentric bushing forms the rotor of the servomotor itself or the eccentric bushing is directly and in particular rigidly connected to a rotor of the servomotor.
    If the servomotor is designed as a separate motor unit, the servomotor can have a motor axis which runs parallel to the extent of the main drive shaft. The motor axis thus also runs parallel to the axis of rotation of the eccentric bushing.
    In particular, if the eccentric bushing has a receiving section on which the coupling rocker is connected, it is advantageous if the eccentric bushing has a further section which is designed concentrically for the passage of the main drive shaft and has, for example, a ring gear or a belt receptacle.
    A further advantageous embodiment of the transmission unit according to the invention provides that a control unit is set up with which the servomotor can be controlled to execute a continuous or discontinuous, periodic and / or repetitive rotary movement of the eccentric bushing.
    The control unit can be formed by an operating unit already present on the comber, or the control unit is an integral part of the existing operating unit. The control unit, which is designed in particular as an interactive interface, can, for example, be used to control the servomotor in order to adjust the phase position of the pilgrim step movement accordingly.
    The tear-off cylinder gear is coupled to the main drive shaft by means of a gear stage in order to form the continuous drive of the tear-off cylinder gear. Furthermore, the tear-off cylinder gear is coupled to the coupling rocker by means of a push-joint rod unit in order to introduce the oscillating movement into the tear-off cylinder gear. The main drive shaft forms a stationary axis of rotation of the eccentric bushing, so that the eccentric bushing can perform the rotational movement on the main drive shaft, especially when the eccentric bushing is rotated or set in rotary motion by the servomotor.
    The invention is also directed to a combing machine for spinning preparation with a gear unit as described above. The combing machine can have several combing units with respective gear units, wherein the control unit can be set up centrally and can be designed to control all servomotors of each gear unit. It goes without saying that the several gear units can be adjusted equally, in particular with regard to the phase position of the tear-off cylinder gear, in particular via a uniform operation.
    Further measures improving the invention are illustrated below in greater detail together with the description of a preferred exemplary embodiment of the invention with reference to the figures.
    1 shows a gear unit for a combing machine according to the prior art; according to the prior art, and FIG. 3 shows a view of a gear unit for a combing machine with the features of the invention.
    First, Figure 1 is described, which shows a gear unit 1 of a combing machine for spinning preparation, the features described with the associated reference numerals in Figure 3 are also to be taken into account, and are not described again in connection with Figure 3.
    Figures 1 and 3 each show a gear unit 1, the gear unit 1 according to Figure 1 represents a prior art, whereas in Figure 3, the features of the invention are described separately.
    The gear unit 1 has a main drive shaft 10 which is driven via a main drive wheel 11 by means of a drive motor 27. The drive motor 27 initially drives a secondary shaft 30, which is part of a secondary transmission 31, the secondary transmission driving, for example, table calender rollers 32 and, for example, delivery rollers 33.
    On the secondary shaft 30, a gear 34 is applied, which meshes with the main drive wheel 11, and the main drive wheel 11 has a rigid connection to the main drive shaft 10, which is consequently also driven by the drive motor 27 to rotate continuously.
    The main drive shaft 10 interacts via an intermediate gear 35 with a circular comb shaft 21, via which a circular comb roller 22 is driven. Furthermore, a gear stage 25 is connected to the main drive shaft 10, via which the tear-off cylinder gear 16 for driving the tear-off cylinders 17 and 18 is continuously driven.
    On the main drive wheel 11, a crank arm 13 is arranged at an eccentric point, via which an oscillating movement is introduced into the tong shaft 12. The oscillating movement is transferred from the tong shaft 12 to a tong apparatus, not shown, in order to move at least one upper tong of the tong apparatus in an oscillating manner relative to a lower tong in order to release the fiber strand between the upper tong and lower tong and to hold it again.
    The pincer shaft 12 is further connected to the coupling rocker 14 via a coupling arm 36, and the oscillating movement of the pincer shaft 12 is introduced into the coupling rocker 14 via the coupling arm 36, which is rigidly attached to the pincer shaft 12. The coupling rocker 14 can execute the rotary oscillating movement on the eccentric bushing 15, which in turn is rotatably mounted on the main drive shaft 10.
    On an opposite side of the connection of the coupling arm 36, the coupling rocker 14 is connected to the tear-off cylinder transmission 16 by means of a push-joint rod unit 26, so that with the oscillating movement of the coupling rocker 14, a discontinuous but periodic oscillating movement is introduced into the tear-off cylinder transmission 16, which is the continuous rotary movement from the main drive shaft 10 and the gear stage 25 superimposed. As a result, the tear-off cylinders 17 and 18 can be driven with the required pilgrim step movement.
    Also shown is a brush motor 37 for driving a cleaning brush 38, and a motor 39 is provided which serves at least to drive two winding rollers 40 on which the fiber lap is placed.
    According to the prior art, FIG. 1 shows a coupling rod 28 as a connection between the main drive wheel 11 and the eccentric bushing 15. Via the coupling rod 28, a rotary movement is introduced into the eccentric bushing 15, which forces the eccentric bushing 15 to rotate as a function of the rotation of the main drive wheel 11 generated.
    FIG. 2 shows the coupling rocker 14 and the eccentric bushing 15 as well as the coupling rod 28 and an eccentric 29 in a perspective view, the eccentric bushing 15 being introduced into a receiving opening 20 centrally in the coupling rocker 14 in the assembled state. In the eccentric bushing 15, in turn, a receptacle for the arrangement of the eccentric 29 is introduced, the eccentric 29 having a bearing passage 41 for the main drive shaft 10 to pass through.
    In comparison to FIG. 1, FIG. 3 shows a drive of the eccentric bushing 15 modified according to the invention without forced guidance by the main drive wheel 11, in that in particular the coupling rod 28 is omitted. The main drive shaft 10 extends from the main drive wheel 11, protruding vertically through the eccentric bushing 15, without a connecting means being located between the eccentric bushing 15 and the main drive wheel 11, which is connected to the eccentric bushing 15 in a torque-transmitting manner.
    The arrangement according to the invention shows a servomotor 19 which is arranged to be operatively connected to the eccentric bushing 15 and with which a rotary movement can be introduced into the eccentric bushing 15. The servomotor 19 is shown as a freely arranged motor and is drivingly connected to the eccentric bushing 15 via a gear connection 23. Alternatively, in a manner not shown in detail, the eccentric bush 15 can also be designed as a unit with the servomotor 19, or the servomotor 19 is an integral part of the eccentric bush 15, so that the gear connection 23 is omitted.
    Furthermore, a control unit 24 is shown, which is connected to the servomotor 19. The servomotor 19 can be controlled via the control unit 24, in particular to control the rotational movement in the eccentric bushing 15, which is introduced into the eccentric bushing 15 with the servomotor 19, in terms of the rotational speed and the phase position or with the rotational profile over time.
    The invention is not limited in its implementation to the preferred embodiment specified above. Rather, a number of variants are conceivable which make use of the solution shown even in the case of fundamentally different designs. All of the features and / or advantages arising from the claims, the description or the drawings, including structural details or spatial arrangements, can be essential to the invention both individually and in a wide variety of combinations.
