Definitions

  • Double-twisting spindle with pneumatically operated threading device Double-twisting spindle with pneumatically operated threading device
  • the invention relates to a double-twisting spindle with pneumatically operated threading device according to the preamble of claim 1.
  • the thread is usually withdrawn from the stationary supply spool upwards, introduced into the upper end of a thread inlet tube, deflected downward and guided by a thread brake in the spindle rotor or in the spindle shaft, which he again through a Fadenleitkanal in the radial direction leaves.
  • the thread After emerging from the Fadenleitkanal the thread is guided upward and forms a twisting around the supply spool balloon. The thread then passes through a thread guide and is twisted twisted onto a package.
  • DE 3012427 C2 discloses a double-twisting spindle with compressed air-operated threading device, in which the spindle rotor has a coaxially extending connecting channel through which compressed air is supplied.
  • the compressed air entering the connecting channel during the threading process flows through the injector and, in the hollow spindle in the upper part of the spindle rotor, generates the suction required for sucking the thread. After completion of the Einfädelvorgangs the compressed air supply is interrupted again.
  • the generic document DE 10250423 A1 shows a double-twisting spindle with a compressed-air-operated threading device, in which the compressed-air channel in the lower part of the spindle shaft is initially guided centrically and before reaching the thread storage disc as an oblique bore.
  • An air channel in an injector element adjoins the compressed air channel in the spindle shaft, which opens into the thread channel as an injector and generates the required air flow radially outwards in the latter.
  • the manufacturing costs of these known designs are high. In particular, the production of the channels in the spindle shaft is expensive.
  • the efficiency of the known designs is insufficiently low.
  • a measure of the efficiency is the static or the dynamic negative pressure, which can be generated in the thread inlet tube or in the thread channel depending on the pressure of the pressure source used. ever lower while the pressure of the compressed air source to achieve a sufficiently high vacuum for sucking the thread, the more economical or efficient the threading is feasible.
  • the formation of the air duct in the known designs for the thread channel limits the efficiency.
  • the abrupt deflection of the air flow by about 90 ° or more causes the compressed air emerging from the compressed air channel initially meets perpendicular to the wall of the injector before the compressed air flow is deflected and accelerated in the injector.
  • the turbulence occurring in the deflection reduce the efficiency of the injector, since the compressed air supply must be made with a higher pressure to compensate for this effect.
  • the compressed air supply comprises a connecting element with a curved air channel which connects the supply bore with the injector, and wherein the connecting element is formed as a separate component and the air duct is adapted to the fluidic requirements.
  • the executed as a separate component connecting element has the significant advantage that it can be easily designed in aerodynamically optimized manner to contribute to the optimization of the compressed air-operated threading device.
  • the production is easy and inexpensive.
  • the inventive fluidic design of the compressed air supply increases the injector effect.
  • the pressure of the compressed air source can be lowered in comparison to known devices, without the negative pressure generated for the suction of the thread decreases.
  • the negative pressure increases at the same pressure of the compressed air source, so that the suction effect is increased to the thread.
  • a calming of the compressed air entering the air duct of the connecting element is achieved by reducing occurring turbulences of the compressed air during the flow through the air duct, which occur after the abrupt deflection on exiting the feed bore into the connecting element. This effect also helps to reduce the air pressure of the supplied compressed air without reducing the efficiency of the threading operation.
  • the injector effect in the injector element is improved at a reduced pressure compared to the prior art, which increases the economic efficiency of the twin-wire twisting spindle with compressed air-operated threading device.
  • Advantageous embodiments of the connecting element according to one of claims 2 to 7 contribute to the particularly streamlined supply of compressed air to the injector and increase the effect of the injector element.
  • the spindle shaft and the thread guide ring preferably have recesses into which the connecting element can be inserted.
  • the angular position of the Fadenleitrings on the spindle shaft is adjustable and fixable by the inserted connection element. If the thread guide ring has been pushed with its recess over the connecting element, the Fadenleitkanal and the output of the injector element are aligned. A rotation of spindle shaft and Fadenleitring each other is not possible in the assembled state, since the inserted connection element acts as a rotation.
  • a connecting element which consists of two firmly interconnected components, which are mirror images of each other, is simple and less expensive to produce compared with a one-piece connector.
  • connection element is made of glass fiber reinforced plastic, it can be produced inexpensively, has little weight and is durable.
  • a sealing ring in each case between the connecting element and the spindle shaft and between the connecting element and the injector element is an inexpensive and functionally reliable sealing of the compressed air supply.
  • the formation of the connecting element as a separate component allows easy production and adjustment of the air duct to the fluidic requirements. This contributes to cost, a double-twisting spindle according to the invention to be able to produce. The economy in threading is improved by low compressed air consumption, which is possible due to the increased injector.

  • Figure 2 is a perspective view of a disassembled
  • Figure 3 is a perspective view of one half of a split connecting element.

  • the bobbin base 9 is rotatable relative to the spindle shaft 2 and is held at a rotating spindle shaft 2 in its position to the bearing housing 4 and the spindle bank 5 by magnetic force of permanent magnets 41.42 with inferences.

  • Such a stationarily arranged compressed air supply to the spindle shaft 2 is described in detail in DE 3012427 C2, for example.
  • the compressed air line 21 terminates at a short distance from the supply bore 24 of the spindle shaft 2. In this embodiment can be dispensed with seals between the pipe mouth 23 and the spindle shaft 2. Compressed air losses are largely avoided.
