Definitions

  • the present invention relates to a spinning box for an open-end rotor spinning device, in particular for a semi-automatic rotor spinning device, the spinning box having a sliver inlet for feeding a fiber structure to an opening unit, which can be arranged in a opening unit receptacle of the spinning box, and a thread outlet opening through which a supplied fiber bundle generated spun thread can be discharged from the spin box.
  • Such a spinning box is, for example, from the document EP 2 963 164 A1 known.
  • Spinning boxes are commonly used to protect the components necessary for the production of a filament from the environment.
  • Known spinning boxes house an opening unit, by means of which a supplied fiber structure is separated into individual fibers and parallelized. The separated fibers are guided via a fiber guide channel leading from the opening unit to a spinning rotor arranged in the spinning box on its fiber chute wall. The rotation of the spinning rotor ensures that the individually supplied fibers slide from the fiber sliding wall into a radial fiber groove of the spinning rotor, in which the individual fibers attach themselves to an open end of a spun thread end deposited in the fiber groove.
  • the spun thread is drawn off from the spinning box via a thread draw-off channel communicating with the spinning rotor cup, as a result of which the spun thread is further developed in the course of continuous tacking so that it can be drawn off.
  • a piecing process is required to resume the spinning process, in which a spinning thread end coming from the package bobbin must be fed into the thread withdrawal channel and fed to the spinning rotor.
  • the end of the spinning thread must be separated and prepared by unraveling or twisting the end of the spinning thread so that the individual fibers can attach more reliably to the open end of the spinning thread.
  • the spinning rotor For this purpose it is usual to prepare the end of the spinning thread by means of a service unit or inside the spinning box by means of the spinning rotor, as for example from the document EP 3 276 057 A1 known to do.
  • the former is advantageous for automatic open-end spinning machines, but unsuitable for semi-automatic open-end spinning machines that do not have a service unit.
  • the latter solution is suitable for this.
  • the spinning rotor must also be driven in a defined manner, which can lead to a shortening of the service life of the spinning rotor drive for pure spinning thread production.
  • the present invention is intended to provide an alternative possibility by means of which a preparation of a spun yarn end for a piecing process is made possible, in particular protected from the ambient air and also suitable in particular for semi-automatic open-end spinning machines.
  • a spinning box is proposed with a fiber sliver input for feeding a fiber structure to an opening unit, which can be arranged in a opening unit receptacle of the spinning box, and with a thread exit opening through which a spinning thread produced from the supplied fiber structure can be discharged from the spinning box.
  • the spinning box according to the present invention is characterized in that the spinning box is designed to accommodate a yarn end preparation unit for preparing a spun yarn end, the yarn end preparation unit being locatable opposite to the yarn exit opening for mutual transfer of a spun yarn.
  • thread end preparation protected from the ambient air can be carried out within the spinning box, in particular independently of a service unit and furthermore in particular without detriment to the service life of a spinning rotor drive.
  • Such a spinning box is particularly suitable for a semi-automatic open-end spinning machine, but can also be used in automatic open-end spinning machines.
  • the spinning box has a thread insertion recess which communicates with the thread exit opening and can be operatively connected to the thread end preparation unit, into which a spun thread can be transferred from the thread exit opening, with the thread insertion recess extending in a defined direction away from the thread exit opening, starting from the thread exit opening.
  • the thread insertion recess thus increases the degree of freedom in the design of the spin box.
  • the yarn end preparation unit can be arranged as required within the spinning box at a selected location, taking into account the space available.
  • the spinning box preferably comprises a first side of the housing and a second side of the housing, which adjoins the first side of the housing at an angle of less than 180°, with the thread outlet opening being formed in the first side of the housing and with the thread insertion recess extending from the thread outlet opening into the second side of the housing extends and is in particular at least partially slit-like.
  • the spinning box has a third side of the housing, which adjoins the second side of the housing at an angle of less than 180°, with the thread insertion recess extending from the thread outlet opening into the third side of the housing and in particular being at least partially embodied as a slot.
  • the first and second and, in particular, the third, housing side are formed by an attachment that can be removably attached to the spin box.
  • the attachment can be done via conventional clamp, snap, screw connections or similar positive and / or non-positive connection types, which allow a non-destructive, repeatable removal of the attachment.
  • Such an attachment favors the reliable transfer of the spun thread from the thread exit opening into the thread insertion recess as well as accessibility to the thread end preparation unit, for example in order to rectify faults or replace wearing parts.
  • the attachment forms at least one last component of the spin box in the withdrawal direction of the spinning thread or more preferably the last component of the spin box, which furthermore preferably forms a component that is raised or protrudes from the other sides of the housing of the spin box.
  • the housing sides of the attachment mounted on the spin box are preferably aligned on the outside surface side with the surface sides of the spin box adjoining these housing sides. Furthermore, a front surface side of the spinning box adjacent to the sliver inlet is preferably formed at least largely or completely from at least one housing side of the attachment.
  • the thread end preparation unit preferably has a thread cutting unit, for example a thread cutting unit, which is arranged in the spinning box opposite the thread insertion recess for cutting a spun thread received in the thread insertion recess.
  • the thread cutting unit can thus be offside of the normal running path of the spun thread, which means that a disruption to the spinning process can be reliably avoided in the event of a possible defect in the thread cutting unit.
  • a thread guide ramp is preferably arranged within the spinning box, which is assigned to the thread insertion recess in such a way that a spun thread inserted into the thread insertion recess can be guided in a defined manner via the thread guide ramp.
  • the thread guide ramp is particularly preferably arranged between the thread withdrawal channel outlet and the thread cutting unit, with the thread guide ramp protruding beyond the thread withdrawal channel outlet along the withdrawal direction of the spun thread, more preferably with a ramp surface extending transversely to the thread withdrawal channel outlet and leading away from it, in order to reliably guide the spun thread into or to a spun thread separating location of the separation unit in the course of loading.
  • the thread cutting unit can be formed in particular by the thread cutting unit having two blade elements that can be moved relative to one another, the blade elements forming a cutting opening for cutting the spun thread.
  • the thread guide ramp is more preferably designed and arranged corresponding to a cutting edge of one of the blade elements, whereby the spun thread is reliably guided into the cutting opening, preferably to the cutting base of the cutting opening, in the course of insertion, in order to enable reliable cutting of the spun thread.
  • a thread sensor is assigned to the thread insertion recess in the spinning box for detecting a spun thread accommodated in the thread insertion recess. More preferably, the thread separating unit can be controlled based on a detection signal of the thread sensor by this or an interposed control unit for separating the spun thread laid in the thread insertion recess. In this way, a separation of the spinning thread can be initialized automatically.
  • the spin box has a cleaning housing, which has a discharge channel that extends along the opening unit receptacle and has an inlet opening that leads to an outside surrounding the spin box is open, with an outlet opening which can be coupled to a dirt channel of the spinning machine, and with a receiving opening which is arranged between the inlet and outlet opening and which is designed to be open to the opening for the opening of the opening unit in order to remove dirt particles from the opening for the opening unit, the cleaning housing being away from the opening has a feed opening leading into the discharge channel for feeding in dirt particles and fiber residues.
  • the feed opening enables the cleaning housing, in particular the discharge channel, to be used to discharge dirt particles from areas of the spin box other than the opening unit receptacle.
  • the cleaning case is as per the document EP 2 963 164 A1 previously known, intended to discharge the dirt particles and fiber residues released in the course of the separation of the supplied fiber structure into a dirt channel of the open-end spinning machine.
  • negative pressure is applied to the discharge channel, with the inlet opening communicating with the ambient air ensuring that there is no constant increase in negative pressure within the opening unit receptacle.
  • this leads to a continuous flow of air in the discharge channel, which is directed from the inlet opening in the direction of the outlet opening, as a result of which dirt particles and fiber residues can be entrained from the opening unit receptacle via the intermediate receptacle opening.
  • the yarn end preparation unit has a yarn end opening unit for opening a spun yarn end inserted into the yarn outlet opening, the yarn end opening unit being formed by a yarn withdrawal channel that can be operatively connected to a spinning rotor and has a yarn withdrawal channel outlet, which is arranged in the spinning box opposite the yarn outlet opening.
  • the discharge opening is formed in the thread draw-off channel in front of the thread-end opening unit in the drawing-off direction of the spun thread.
  • the feed opening is preferably arranged between the inlet opening and the receiving opening, in particular close to the inlet opening, more preferably immediately downstream of the inlet opening. This makes it easier to access the feed opening, for example for cleaning purposes.
