Definitions

  • the invention relates to a spinning station device for a ring spinning machine comprising a spindle for a bobbin which is mounted on a spindle bank in a rotationally drivable manner and an encapsulation which runs in the longitudinal direction of the spindle and encloses the bobbin.
  • Machines for spinning processes with closed end and true twist such as ring spinning, funnel spinning, loop spinning, spinning with rotating rings, spinning with floating rings, spinning with balloon limitations of all kinds (multi-balloon, balloon constriction sleeves standing and moving, balloon reductions such as spinning crowns, spinning fingers, balloon constriction rings, etc.), pot spinning, Murano spinning, are well known.
  • Thread is the generic term for yarn, filament and twisted yarn. In the following, we will generally refer to “yarn” and “spinning”. However, the expert knows 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 winding packages on the machine must be rotated (otherwise the machine would have to be rotated around the package).
  • the package body 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 are usually encapsulated in a cylindrical sleeve whose diameter is a few millimeters larger than the cop or the balloon. This works, but hinders access to the cop in various operating situations, such as when repairing a thread break or when piecing.
  • a special form of balloon encapsulation is the balloon constriction sleeve, as used for example in DE1510657B1 or DE19848752A1 described.
  • the spool or cop rotates on the axis of a spindle and is connected to it, for example, by friction.
  • the spindle can be driven by a belt drive or by a single motor.
  • the spindles are usually attached to a spindle bank. This can be fixed or movable in the axial direction of the spindle.
  • a relative movement in the axial direction of the bobbin (or spindle) must be realized between this and an element for defining the thread laying, so that not all of the yarn is wound up in the same place as a bead, but in a bobbin structure shape that can be determined by the relative movement (e.g. as a cop winding).
  • Organs for laying the thread include, for example, the ring and traveller, 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 laying the thread are usually attached next to each other on a long element, which, depending on the element, is called a ring, funnel, bell or thread guide bank or frame.
  • the relative movement can be achieved by moving one or both elements relative to each other.
  • the ring rail is moved and the spindle rail is fixed to the machine frame.
  • Encapsulations can be attached to the ring rail, as shown in CH683349A5 (and DE1510657B1 or DE19848752A1 ), whereby only a certain, small part of the spinning area is encapsulated. The energy savings are small.
  • CN209957949U shows an incomplete encapsulation that is installed below the ring rail, but shows an upwardly displaced, extended attachment 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 drive and bearing construction of the spindle is inconveniently long to allow the spindle to plunge into the enclosure.
  • DE1685679A1 shows two different encapsulation variants that can be shortened, but they do not have the optimal diameter for energy along 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, whereby the spindle moves into the enclosure.
  • a complex, long spindle shape is necessary.
  • WO2020105006A1 describes a long, magnetically mounted spindle that is suitable for moving into an enclosure attached to a ring rail. The effort required to use the enclosure is considerable.
  • CH715908A1 shows a multi-balloon process with a fixed ring bank and a moving spindle bank, which allows the majority of the balloons to be kept constant.
  • the great effort and enormous construction height required to encapsulate both the balloon above the ring bank and the cop below the spindle can also be seen.
  • the energy savings are also reduced due to the large, rotating air volume.
  • JP2013170337A describes a spinning machine in which the casing is permanently attached to the spindle bank.
  • the casing is slotted and the functional part of the ring bank is attached to the inside of the machine, behind the casing, so that the ring holder of the ring bank reaches through the slot from the outside and the ring is guided axially within the casing.
  • the machine structure is essentially conventional and the casing is only as high as the function requires, but among other disadvantages, the accessibility of the spinning station is poor.
  • the spinning machine is difficult to operate in certain operating situations. In any case, the spinning station must be stopped and made accessible in certain operating situations, such as a thread break or when piecing onto the bare tube.
  • CN210194054U solves the problem of integrating the thread guide and guides the spinning ring by magnets held from the outside within the encapsulation, without the need for a slot.
  • the thread guide is integrated into the cover and the height is optimized.
  • the Encapsulation rotates and would require encapsulation itself to save energy.
  • the technical effort is high.
  • the spinning station is very difficult to access.
  • the spindle must be started with a fully twisted thread.
  • the thread receives additional twists in the same piece of yarn, which can lead to the thread being over-twisted and breaking if the piecing is too slow or the spinning speed is too fast.
  • One object of the present invention is to enable complete encapsulation of a spindle or a bobbin, which allows simple access to the spindle, compatible with the design of a conventional ring spinning machine.
  • a further object is to enable accessibility with simple operation of an individual spinning station, especially in the event of a thread break. In particular, it should be possible to repair a thread break in the 6 to 10 seconds that are usual today.
  • This object is achieved by a spinning station device with the features of claim 1.
  • the spinning station device for a ring spinning machine comprises a spindle for a bobbin (i.e.
  • a bare tube or a bobbin with wound yarn that is mounted on a spindle bank in a rotationally drivable manner and an encapsulation that runs in the longitudinal direction of the spindle and encloses the bobbin, the encapsulation being connected to the spindle bank.
  • the encapsulation is divided in the longitudinal direction and has a rear capsule wall and a front, operator-side capsule 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 can be pivoted into a preferably horizontal position.
  • the front 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.
  • a ring spinning machine the axes of rotation of the spindles in the individual spinning stations run vertically.
  • the spindles are mounted on a spindle bank at the lower end so that they can be driven in rotation.
  • As the front, operator-side encapsulation wall is mounted so that it can rotate at the lower end, it can reliably ensure that the spool body is accessible from the front, i.e. from the operator side of the ring spinning machine, when it is swung out from a vertical, closed position to a horizontal, open position, so that machine piecing or automatic or manual operation in the event of a thread break is possible without any problems.
  • Such encapsulation is also suitable for retrofitting existing spinning machines.
  • the rear capsule wall can be firmly connected to the spindle bank and the front capsule wall can be pivotally connected to the rear capsule wall.
  • the rear capsule wall can, for example, have two laterally arranged and forward-projecting legs on which the front capsule wall is pivotally held, e.g. by means of an axis.
  • the front capsule wall can also be pivotally connected to the spindle bank, or to a holder attached to the spindle bank.
  • the rear capsule wall and the front capsule wall can each be designed as a partial shell, which are preferably connected to one another with a hinge in the area of the spindle bank. 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 also has a spindle brake, which can be actuated by opening the encapsulation in order to brake the spindle or the bobbin.
  • a spindle brake which can be actuated by opening the encapsulation in order to brake the spindle or 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, fast braking is also necessary, for example, to repair a thread break in the shortest possible time.
  • Spindle brakes are known per se and are usually designed in such a way that they can be operated by the operator with the knee, so that both hands are free to repair the thread breakage.
  • the front capsule wall can have a brake actuation device that actuates the spindle brake by moving the front capsule wall into the open position.
  • a brake actuation device that actuates the spindle brake by moving the front capsule wall into the open position.
  • the spindle brake is controllable in its braking force.
  • the spindle brake can be infinitely controlled in its braking force. With a controllable braking force, the spindle can be braked quickly or slowly to a standstill as required. Conversely, the start-up of the spindle can be regulated by closing the enclosure or the front enclosure wall, so that the spindle has the speed required for spinning.
  • the braking effect of the spindle brake can increase with 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 with increasing degree of opening of the encapsulation.
  • the spindle or the bobbin is braked.
  • the braking effect decreases and the spindle or the bobbin begins to rotate again.
  • the front capsule wall acts like a brake lever to regulate the speed of the spindle.
  • the start-up of the spindle can be regulated, especially when the encapsulation is closed, so that the optimal speed for twisting in the yarn at the end of the thread break repair is achieved.
  • the spindle runs again at the operating speed and the spinning process continues.
  • the spindle brake may be arranged between the bobbin and the whorl or between the whorl and the bobbin bearing.
  • the spindle brake can be designed 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 designed to be spring-loaded.
  • a clamping jaw for braking the spindle can be formed at one end of each of the two brake levers, which are placed around the spindle for this purpose.
  • the 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 presses these ends of the brake levers apart. The clamping jaws are pressed together and brake the spindle.
  • the two brake levers can have slanted stop surfaces at the end into which the brake actuation device is inserted (i.e. the end facing away from the spindle), which approach the hinge.
  • the braking effect can increase as the encapsulation is opened or the brake actuation device is inserted 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 constant. This is particularly advantageous if a spindle decoupling device as described below is also used.
  • the spindle brake e.g. with a brake shoe and a guide rail for a brake actuation device of the encapsulation, are also possible.
  • the guide rail can be designed in such a way that the braking effect increases depending on the degree of opening of the encapsulation and is kept constant if necessary from a certain degree of opening.
  • Spinning actuators can be provided with individual spindle drive units, or one drive unit can drive several spinning actuators, for example via a drive belt.
  • the spinning station device can have a single spindle drive unit that can be controlled by opening or closing the encapsulation (similar to the spindle brake described).
  • the spinning station device can be provided with a drive control unit that can be actuated by opening and closing the encapsulation.
  • opening the encapsulation the speed of the drive device can be reduced or the drive device can be switched off completely.
  • closing the encapsulation the speed of the drive device can be increased or the drive device can be switched on again.
  • the control system can be mechanical and/or electronic.
  • the spinning station device can have a spindle decoupling device which decouples a drive element of the ring spinning machine from the spindle by opening the capsule, preferably when the front capsule wall is swung out into the open position.
  • the drive element can be a drive belt which is attached to a whorl of the spindle to operate the spindle.
  • Such a spindle decoupling device is advantageous in order to avoid overheating of the braked spindle, for example due to a drive belt that continues to run.
  • the spindle decoupling device can have a decoupling roller, which can be mounted so that it can move 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 correspondingly decoupled from the spindle and the spindle can be braked more easily.
  • Decoupling or switching off a drive unit is particularly advantageous if the spinning station has to stand still for a longer period of time due to a defect.
  • the spindle brake and the spindle decoupling device or the drive control unit can be combined with one another.
  • the spindle brake and the spindle decoupling device or the drive control unit can be designed in such a way that by opening the encapsulation, preferably when the front capsule wall is swung out into the open position, the spindle brake is first actuated to the maximum braking effect and only then is the drive element of the ring spinning machine decoupled from the spindle.
  • the spindle brake and the spindle decoupling device or the drive control unit can be designed in such a way that by closing the encapsulation, the drive element of the ring spinning machine is first coupled to the spindle before the spindle brake is then released.
  • the front capsule wall can have an actuating arm for actuating the spindle decoupling device or the drive control unit.
  • the decoupling roller can be attached to a horizontally guided carriage, for example, whereby the carriage can be actuated by means of a toggle lever.
  • the actuating arm can be actuated on the toggle lever when the front capsule wall is swung out. and thus decouple the drive element.
  • 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 only decoupled after it has been braked. This is particularly advantageous so that when the encapsulation is closed, the spindle is first coupled to the drive element before the braking effect is removed, in order to allow reliable regulation of the braking effect or a gradual removal of the braking effect when closing.
  • the combination of the encapsulation with the spindle brake that can be regulated depending on the degree of opening of the encapsulation can also be considered an independent invention.
  • the gradual regulation of the spindle brake itself can be considered an independent invention.
  • the spindle decoupling device alone or in combination with the encapsulation with or without a spindle brake can also be considered an independent invention.
