Definitions

  • the invention relates to a spindle for producing a yarn or twine with the features from the preamble of patent claim 1.
  • the flowable medium can be, for example, conditioned air, but also two-phase media such as air and in it Suspended drops of suitable liquids, solid particles or dissolved fiber material that are intended to have special effects on the thread or yarn.
  • a spindle rotor as part of a device for producing a yarn or twisted thread, in which a fluid medium flows into the space delimited by the thread balloon through the spindle rotor is initiated.
  • the spindle rotor has a plurality of guide blades arranged in the form of a spoke, the thread guide channel running through one of these guide blades.
  • the flowable medium is supplied from the outside essentially parallel to the spindle rotor axis, and the feed devices must be arranged in front of the spindle rotor in the relatively cramped space that is often also required for other equipment parts, and the feed lines must be led into this area.
  • the guide blades of the spindle rotor have proven to be a hindrance to the free flow, in particular of solid particles, and ambient air is additionally conveyed through the spindle rotor as a result of the ventilation effect, which can lead to dirt deposits on the guide blades, which causes further undesirable effects on the entry of the medium can.
  • the invention has for its object to provide a spindle of the type described in the preamble of claim 1 such that a fluid medium can be introduced without interference in the space delimited by the thread balloon can be arranged axially in front of the spindle rotor in the confined space without the necessary devices.
  • the invention is based on the surprising finding that it is possible to introduce a flowable medium in a radial direction through the thread balloon into the space delimited by the thread balloon.
  • the pure thread balloon also proved to be surprisingly stable in relation to the disturbance caused by the multiphase media stream passing through. If, however, contact between the circulating thread and the flowable medium to be introduced is to be avoided, the introduction of the medium can be controlled by switching on / off or switching to supply lines arranged at different locations on the thread balloon so that there is no contact between the flow of the treatment medium and the circulating thread takes place.
  • FIGS. 1 to 3 only a few parts of a double-wire twisting spindle that are essential for the following explanation are shown, namely in FIG. 1 the spindle rotor 1 driven via an axis extension 1.1, which contains the radially outwardly directed thread guide channel 2 in the region of the spindle axis A. , and a bobbin with protective pot 6 arranged above the spindle rotor 1, in which an untwisted yarn supply, for example in FIG. 1, a bobbin S is inserted.
  • the coil carrier with protective pot 6 is placed on the spindle rotor 1 with bearings (not shown) and is held in its position in a rotationally fixed manner by means of permanent magnets SN.
  • the bobbin with protective pot 6 is surrounded by a balloon limiter 5.
  • the threads F1 and F2 drawn off from the yarn supply S are guided through the thread inlet tube 4 along the spindle axis A to the center of the rotor, and the thread F emerging from the thread guide channel 2 becomes in the space between the bobbin with protective pot 6 and the balloon limiter 5 guided to a centering point Z, which is designed as a narrow thread guide eyelet, so that in the area between the bobbin with protective pot 6 and balloon limiter 5 a thread balloon is formed during operation.
  • a line 3 which is brought in radially in the direction of the spindle through a holder 7, ends in an opening 5.1 of the balloon limiter 5.
  • the outlet opening 5.1 is opposite an inlet opening 6.1 in the jacket of the protective pot 6.
  • This inlet opening 6.1 has a slightly larger diameter than the outlet opening 5.1 and is drawn in in a funnel shape in order to create favorable flow conditions for the flowable medium M1 supplied through the line 3.
  • the medium flows through a single line 3, passes through the thread balloon between the openings 5.1 and 6.1, and then reaches the interior of the protective pot 6. With continuous inflow, it can come into contact with the thread F circulating in the thread balloon. If such a contact is to be avoided, for example, the medium M1 can either be supplied in a discontinuous manner in clocked operation or, if an uninterrupted supply is necessary or desirable, the device shown in FIG. 1 in the manner shown in FIGS. 2 or 3 can be varied.
  • the line 3 led through the holder 7 is divided in its last section into two branch lines 3.1 and 3.2, which in a predetermined distance in the circumferential direction via outlet openings 5.'1 and 5. "1 open into the space to the inner balloon limiter 5.
  • the outlet openings 5.'1 and 5.” 1 are again opposite an inlet opening 6.'1 in the jacket of the coil carrier with protective pot 6, which is drawn in in a funnel shape and whose diameter is dimensioned such that both a flow of the medium emerging from the outlet opening 5.'1 and an outlet opening 5.'1 through the inlet opening 6.'1 into the The inside of the coil carrier is steered with protective pot 6.
  • control flap 8 which can be switched by means of a control device C and through which the branch line 3.1 or the branch line 3.2 can alternately be made continuous for the flow of the flowable medium is controlled so that during the movement of the thread F in the thread balloon, for example, the flow of the fluid Medium M2 initially runs through the branch line 3.2 until the thread F has passed the outlet opening 5.'1 of the branch line 3.1. At this moment, the control flap 8 is reversed so that the flow of the medium flows through the branch line 3.1 in a manner not shown.
  • the flowable medium can be steered by the suitably controlled control flap 8 in such a way that it does not meet the thread F of the thread balloon passing in front of the outlet openings 5.'1 and 5.'1.
  • the control flap 8 a rotary diaphragm can also be used, as described below.
  • the two branch lines are arranged at a relatively short distance in the circumferential direction. It can of course prove to be useful if this distance is increased.
  • FIG. 3 Such an embodiment is shown in FIG. 3.
