Definitions

  • the invention relates to a spinning station device for a ring spinning machine, comprising a spindle for a bobbin that is fastened in a rotationally drivable manner on a spindle rail and an encapsulation that runs in the longitudinal direction of the spindle and encloses the bobbin.
  • Machines for closed end and true rotation spinning processes such as ring spinning, funnel spinning, loop spinning, rotating ring spinning, floating ring spinning, spinning with balloon confinement of all kinds (multiballoon, balloon constriction sleeves standing and moving, balloon reductions like spinning crowns, spinning fingers, balloon constriction rings, etc.) , pot spiders, Murano spiders, are well known.
  • Thread is the generic term for yarn, filament and twine.
  • the terms “yarn” and “spiders” are generally used. However, the person skilled in the art is aware that the terms can also apply to "thread” and "twisting”.
  • the reason for the exponential increase in energy consumption is that in closed-end spinning processes with simple true twist, the packages on the machine must necessarily be rotated (Otherwise the machine would have to be rotated around the bobbin.).
  • the bobbin usually in the form of a cop, then acts as a fan.
  • Encapsulations are known for the purpose of saving energy by reducing the air mass to be accelerated.
  • the cop and/or the thread balloon is usually encapsulated by a cylindrical sleeve, the diameter of which is a few millimeters larger than the cop or the balloon. This works, but hinders access to the bobbin in various operating situations, such as when repairing a broken thread or when piecing.
  • a special form of balloon encapsulation is the balloon constriction sleeve, such as that shown in DE1510657B1 or DE19848752A1 is described.
  • the bobbin or cop rotates on the axis of a spindle and is connected to it, e.g. by friction.
  • the spindle can be driven by a belt drive or by a single motor.
  • the spindles are usually fixed in a spindle bank. This can be designed to be fixed or movable in the axial direction of the spindle.
  • a relative movement in the axial direction of the bobbin (or the spindle) must be realized between this and a device for defining the thread laying, so that not all yarn is wound up at the same point as a bead, but in a bobbin build form that can be determined by the relative movement (e.g. as head winding).
  • Organs for thread laying are e.g. ring and runner, the bell or funnel edge in bell, funnel or loop spinning or a thread guide in funnel or Murano spinning, thread guide tubes or similar.
  • the elements for thread laying are usually fastened next to each other on a long element which, depending on the element, is called, for example, a ring, funnel, bell or thread guide bank or frame.
  • the relative movement can be realized by moving one or both elements relative to one another.
  • the ring rail is moved and the spindle rail is fixed to the machine frame.
  • Enclosures can be attached to the ring rail as shown in CH683349A5 (and DE1510657B1 or DE19848752A1 ) is described, with only a specific, small part of the spinning area being encapsulated here. The energy saving is small.
  • CN209957949U Figure 12 shows an incomplete encapsulation fitted below the ring rail but showing an upwardly displaced, extended mounting of the spindle with a single motor drive.
  • the encapsulation is not complete and the spindle is relatively unstable, whereby the air gap of the external rotor cannot be kept constant due to the precession of the spindle.
  • CH706759A1 shows an enclosure that completely and efficiently encapsulates the cop below the ring rail, but the spindle drive and bearing design is unfavorably long to allow the spindle to dip into the enclosure.
  • DE1685679A1 shows two different encapsulation variants that can be shortened, which, however, do not have the energetically optimal diameter over their entire length, nor are they stable, dirt-resistant and easy to clean. In addition, they do not offer easy accessibility.
  • EP3483313A1 describes a moving spindle bank, with the spindle entering the enclosure. Here, too, a complex, long spindle shape is necessary.
  • WO2020105006A1 describes a long magnetically levitated spindle suitable for retracting into an enclosure attached to a ring rail. The effort required to use the encapsulation is considerable.
  • CH715908A1 shows a multi-balloon method with a fixed ring rail and a moving spindle rail, which allows the majority of the balloons to be kept constant.
  • the great effort and the enormous overall height that are necessary to encapsulate both the balloon above the ring rail and the cop below the spindle can also be seen.
  • the energy saving is also reduced by the large, rotated air volume.
  • JP2013170337A describes a spinning machine in which the encapsulation is fixed to the spindle rail.
  • the encapsulation is slotted and the functional part of the ring rail is attached to the inside of the machine, behind the encapsulation, so that the ring holder from the ring rail reaches through the slit from the outside and the ring is guided inside the encapsulation in the axial direction.
  • the machine design is essentially conventional and the encapsulation is only as high as the function requires, but among other disadvantages, the accessibility of the spinning position is particularly poor.
  • the spinning machine is difficult to operate in certain operating situations. In any case, the spinning position must be stopped and made accessible in certain operating situations, such as a yarn breakage or when piecing onto the bare tube.
  • CN210194054U solves the problem of integrating the thread guide and guides the spinning ring held by magnets from the outside inside the encapsulation without the need for a slot.
  • the thread guide is integrated into the cover and the overall height is optimized.
  • the Encapsulation rotates and would need an encapsulation itself to save energy.
  • the technical effort is high.
  • the spinning station is very difficult to access.
  • the spindle must inevitably be started with a finished twisted thread.
  • the thread is given additional twists in the same piece of yarn, which can lead to the thread being overtwisted and breaking if the piecing is too slow or the spinning speed is too fast.
  • An object of the present invention is a complete encapsulation of a spindle, respectively. to allow a bobbin, which allows a simple, compatible with the construction of a conventional ring spinning machine accessibility to the spindle.
  • a further object is to enable accessibility with a simple operation of a single spinning station, especially in the event of a thread breakage. In particular, it should be possible to remedy a yarn breakage in the 6 to 10 seconds that are usual today.
  • the spinning position device for a ring spinning machine comprises a spindle for a bobbin (i.e. a bare bobbin or a bobbin with wound yarn) that is fastened on a spindle rail in a rotationally drivable manner and an encapsulation running in the longitudinal direction of the spindle and enclosing the bobbin, the encapsulation being connected to the spindle rail.
  • the encapsulation is divided longitudinally and has a rear encapsulation wall and a front, operator-side encapsulation wall. The front capsule wall can be moved into an open position, so that in the open position the bobbin of the spinning station device is accessible for operation.
  • the front capsule wall can be pivotally connected at a lower region and pivoted into a preferably horizontal position.
  • the anterior capsule wall can be brought into an open position by a linear movement, by pivoting about the spindle axis or by a sliding movement or the like.
  • the invention has the advantage that the encapsulation can be opened very easily.
  • the axes of rotation of the spindles run vertically in the individual spinning positions.
  • the spindles are rotatably driven on a spindle rail.
  • the front, operator-side capsule wall is rotatably mounted at the lower end, it can reliably guarantee accessibility to the bobbin from the front, i.e. from the operating side of the ring spinning machine, when swinging out from a vertical, closed position to a horizontal, open position, so that a machine Piecing or automatic or manual operation in the event of a thread breakage is made possible in a problem-free manner.
  • Such an encapsulation is also suitable for retrofitting existing spinning machines.
  • the posterior capsule wall may be fixedly connected to the spindle rail and the anterior capsule wall may be pivotally connected to the posterior capsule wall.
  • the rear capsule wall can have, for example, two laterally arranged and forwardly projecting legs, on which the front capsule wall is held pivotably, for example by means of an axis.
  • the front capsule wall can also be pivotally connected to the spindle rail, resp. with a bracket attached to the spindle bench.
  • the rear capsule wall and the front capsule wall can each be designed as partial shells, which are preferably connected to one another with a hinge in the area of the spindle rail. Together, the partial shells enclose 360° of the spindle axis.
  • the partial shells can be designed as two half-shells, each of which encloses 180°. Other divisions are also conceivable.
  • the spinning station device can also have a spindle brake, which can be actuated by opening the enclosure in order to respectively rotate the spindle. decelerate the bobbin.
  • a spindle brake can be actuated by opening the enclosure in order to respectively rotate the spindle. decelerate the bobbin.
  • Such a mechanical spindle brake is often necessary because the bobbins can no longer be braked by hand due to the high speed. Reliable, rapid deceleration is also necessary in order, for example, to rectify a thread breakage in the shortest possible time.
  • Spindle brakes are known per se and are usually designed in such a way that they are actuated by the operating personnel with their knees, so that both hands are free to fix the thread breakage.
  • the anterior capsule wall may include a brake actuator which actuates the spindle brake by moving the anterior capsule wall to the open position.
  • a brake actuator which actuates the spindle brake by moving the anterior capsule wall to the open position.
  • the spindle brake can be controllable in its braking force, preferably continuously controllable. With a controllable braking force, the spindle can be braked quickly or slowly to a standstill as needed. Conversely, the starting of the spindle by closing the encapsulation resp. of the front capsule wall can be regulated so that the spindle has the speed required for piecing.
  • a braking effect of the spindle brake can increase with an increasing degree of opening of the encapsulation up to a maximum braking effect.
  • the spindle brake can be actuated via the brake actuation device attached to the front capsule wall.
  • the spindle brake and the brake actuation device can be designed in such a way that the braking effect increases as the degree of opening of the encapsulation increases.

  • the front capsule wall acts like a brake lever to regulate the speed of the spindle.
  • the spindle brake may be located between the spool body and the whorl or between the whorl and the spool bearing.
  • the spindle brake may be in the form of a clamp or pliers.
  • the clamp can have a first brake lever and a second brake lever, which are connected to one another via a hinge.
  • One of the brake levers can also be resilient.
  • a clamping jaw for braking the spindle can be formed at one end of each of the two brake levers and is placed around the spindle for this purpose.
  • the respective other end of the two brake levers can be designed in such a way that the brake actuation device can be inserted between the two brake levers and push these ends of the brake levers apart. The clamping jaws are pressed together and brake the spindle.
  • the two brake levers at the end into which the brake operating device is inserted can have inclined abutment surfaces which converge towards the hinge. In this way, the braking effect with increasing opening of the encapsulation, respectively. increasing introduction of the brake actuator between the brake levers. From a predetermined insertion depth, the two stop surfaces can run parallel to one another, so that if the brake actuation device is inserted further, the braking effect no longer increases, but remains maintained. This is particularly advantageous if a spindle decoupling device described below is also used.
  • the link guide can be designed in such a way that the braking effect increases as a function of the degree of opening of the encapsulation and, if necessary, is kept constant from a certain degree of opening.
  • Spinning adjustment devices can be provided with individual spindle drive units, or one drive unit can drive several spinning adjustment devices, for example via a drive belt.
  • the spinning position device can have a single spindle drive unit, which can be controlled by opening or closing the enclosure (similar to the spindle brake described).
  • the spinning position device can be provided with a drive control unit that can be actuated by opening and closing the encapsulation. By opening the encapsulation, the speed of the drive device can be reduced or the drive device can be switched off entirely. Conversely, by closing the enclosure, the speed of the Increased drive device or the drive device can be switched on again.

  • the drive element can be a drive belt which rests against a whorl of the spindle in order to operate the spindle.
  • Such a spindle decoupling device is advantageous in order to avoid overheating of the braked spindle, e.g. if the drive belt continues to run.
  • the spindle decoupling device can have a decoupling roller, which can be movably mounted in the direction of the drive belt, so that the decoupling roller pushes the drive belt away from the whorl when the spindle decoupling device is actuated.
  • the drive belt is decoupled from the spindle and the spindle can be braked more easily.
  • the decoupling or switching off of a drive unit is particularly advantageous if the spinning position has to be idle for a longer period of time due to a defect.
  • the spindle brake and the spindle decoupling device can be combined with each other.
  • the drive control unit can be designed in such a way that by opening the encapsulation, preferably when the front encapsulation wall is pivoted out into the open position, first the spindle brake is actuated up to the maximum braking effect and only then is the drive element of the ring spinning machine decoupled from the spindle.

  • the actuating arm can be designed in such a way that it only acts on the spindle decoupling device when the encapsulation is almost completely opened, so that the spindle is decoupled only after it has been braked. This is particularly advantageous so that when the enclosure is closed, the spindle is first coupled to the drive element before the braking effect is canceled in order to ensure reliable regulation of the braking effect, respectively. to allow a gradual elimination of the braking effect when closing.
