Definitions

  • the invention relates to a yarn delivery device for a twisting or cabling machine, a work station of a twisting or cabling machine comprising such a yarn delivery device and a twisting or cabling machine comprising such a job.
  • a twisting machine on which the twisted thread is guided via a deflection roller to a delivery device comprising a godet and a laying roller.
  • the twine is guided with several wraps around the godet and the laying roller and runs from the godet to a deflection roller which is arranged at the free end of a pitching lever and has a horizontal axis of rotation.
  • the free end of the pitching lever is located in front view of the delivery device, while the other end of the pitching lever is mounted on a support plate on a support plate so as to be pivotable about a horizontal axis below the delivery device.
  • the thread runs over a traversing thread guide known per se to a winding spool.
  • the traversing thread guide performs an oscillating movement along the surface of the take-up spool and parallel to its axis, which leads to a uniform winding of the thread on the take-up spool.
  • the pitch lever is used for length compensation. Due to the pendulum movements of the pitch lever, the angle of inclination of the thread entering the traversing thread guide differs according to the maximum angular positions of the pitch lever. This results in different states in the area of the point at which the thread runs onto the take-up spool.
  • a twisting machine can be used in accordance with the DE 199 24 595 C1 swivel the pitch lever to one side about a vertical axis. At least one sensor detects both the pivoting of the pitch lever about the horizontal and the pivoting about the vertical axis and generates a signal when a predetermined limit value of the pivoting is exceeded.
  • a first aspect of the invention therefore relates to a thread delivery device for a twisting or cabling machine, for feeding a thread via a traversing thread guide to a take-up reel, the thread delivery device comprising a first deflection roller for deflecting a thread, a driven godet connected downstream in the thread transport direction of the first deflection roller Laying roller arranged in relation to the godet such that a thread can be laid several times around the laying roller and the godet, wrapping them together, and a pitch lever with a second deflecting roller connected downstream in the thread transport direction of the godet for further deflection of the thread.
  • the proposed thread delivery device is characterized in that a boom with a third deflecting roller, which is connected downstream of the second deflecting roller in the thread transport direction and upstream of the traversing thread guide for feeding the thread onto a package, is arranged, the second deflecting roller on another side through the axis of rotation of the Laying roller extending vertical plane is arranged as the third deflecting roller for receiving the thread from the laying roller or the godet and for deflecting the thread in the direction of the third deflecting roller.
  • the pitch lever is arranged in front view behind the godet and not, as before, in front of the thread delivery device, the available space around the thread delivery device is increased. Due to the increased free space under the thread delivery device, in order to replace an empty supply spool with a new, full one, according to the invention, no pitch lever has to be pivoted aside, so that the loading of the spindle is simplified.
  • the placement advantage applies particularly to small pitches.
  • the entry angle of the thread into the traversing thread guide is defined and constant during the entire process.
  • the angle of inclination of the thread entering the traversing thread guide was different due to the necessary pendulum movement of the pitch lever in accordance with the angular positions of the pitch lever.
  • the inventive design of the thread delivery device with the third deflection roller which is arranged in a fixed position on a boom, always ensures a constant and exact last deflection point of the thread before it enters the traversing thread guide, so that the angle of inclination with which the thread runs into the traversing thread guide, is also constant. This has a positive effect on the thread package quality.
  • the pitch lever causes voltage fluctuations caused by the back and forth Traversing thread guides are caused, absorbed.
  • the traversing thread guide was in its middle position, its distance from the deflection roller of the pitch lever was shorter than in the two reversing positions.
  • This direct thread tension compensation at the traversing triangle is alleviated by the thread delivery device according to the invention, because the thread is fed from the pitch lever to the traversing thread guide via a stationary third deflection roller.
  • the thread can either be guided, as before, from the godet of the second deflection roller of the pitch lever or from the non-driven laying roller to the pitch lever.
  • the thread tension compensation is further optimized by dispensing the thread from the passive laying roller, since a significantly larger compensation path is used.
  • the pitch lever and / or the boom are arranged on a housing of the thread delivery device.
  • the second deflection roller and the third deflection roller are arranged on the same side of a horizontal plane running through the axis of rotation of the laying roller.
  • This arrangement of the pitch lever makes it possible to further enlarge or optimize the work area for the operating personnel.
  • the pitch lever with its free end on which the second deflection roller is mounted is arranged above the godet in the area of the thread delivery device.
  • This arrangement of the pitch lever makes it possible to enlarge the working area for the operating personnel as much as possible.
  • the second deflection roller is arranged on another side of a horizontal plane running through the axis of rotation of the laying roller than the third deflection roller.
  • the pitch lever with its free end on which the second deflection roller is mounted protrudes below the thread delivery device.
  • Such an arrangement is particularly advantageous and ensures, on the one hand, a generous free space for exchanging the supply spool and, on the other hand, easy accessibility of the pitch lever, in the event that the thread has to be guided manually over the second deflection roller.
  • a second aspect of the invention therefore relates to a work station of a twisting or cabling machine, for winding a thread over a traversing thread guide onto a take-up reel, with a thread delivery device comprising a first deflection roller, for deflecting a thread, a driven godet connected downstream in the thread transport direction of the first deflection roller Laying roller arranged to the godet in such a way that a thread can be laid several times around the laying roller and the godet, wrapping them together, a pitching lever with a second deflecting roller connected downstream in the thread transport direction of the godet for further deflection of the thread.
  • the job is characterized in that the thread delivery device is a thread delivery device according to one of the embodiments described above.
  • the work station is equipped with a thread delivery device designed in this way, this has a positive effect on the thread bobbin quality on the one hand, and handling for the operating personnel is facilitated on the other hand.
  • the pitch lever still absorbs the tension fluctuations caused by the oscillating traversing thread guide, but without now due to the pendulum movements to cause fluctuating angles of inclination of the incoming thread in the traversing thread guide.
  • the compact design optimizes the free space and the accessibility of the workplace.
  • the master spool placed on the spindle can be exchanged for a new master spool more easily and quickly, since it is no longer necessary to swing the pitching lever sideways for loading.
  • the pitch lever does not affect the work area in which the supply spools are manually removed from the spindle or placed on the spindle, whereas previously the pitch lever pivoted to the side still protruded into the work area.
  • a third aspect of the invention therefore relates to a twisting or cabling machine with a plurality of workstations for winding a thread over a traversing thread guide onto a take-up reel, with a thread delivery device comprising a first deflecting roller, for deflecting a thread, a driven godet connected downstream in the thread transport direction of the first deflecting roller , a laying roller arranged in relation to the godet in such a way that a thread can be laid several times around the laying roller and the godet, wrapping them together, a pitch lever with a second deflecting roller connected downstream in the thread transport direction of the godet for further deflection of the thread.
  • the twisting or cabling machine is characterized in that at least one job is formed by a job according to the embodiment described above.
  • twisting or cabling machine designed in this way, overall machine operation is made easier for the staff, which likewise has a positive effect on the efficiency of the entire twisting or cabling machine. Since one person usually looks after several machines, each with a large number of workstations, less necessary work steps mean a time and effort advantage.
  • pivoting pitch lever which no longer protrudes into the working area, reduces error sources which result from incorrect positioning of the pitch lever when pivoting out or in or out into the working area.
  • Such a twisting and cabling machine can also produce a qualitatively optimized twine or twist bobbin, since the constant angle of inclination of the thread during the entry into makes the traversing thread guide positively noticeable.
  • a twisting or cabling machine 1 is shown in a schematic front view.
  • Textile machines of this type each have a multiplicity of identical work stations 2 in the area of their machine longitudinal sides.
  • textile machines of this type generally have a drive and operating unit 6 arranged on the machine end, in which, for example, the required energy devices, various drives and a central control device 7 are installed.
  • the twisting or cabling machine 1 also has a bobbin transport system, the schematically illustrated delivery point of which is identified by the reference number 8.
  • the work stations 2 of twisting or cabling machines 1 with outer thread feeder each have a creel 3, which serves to accommodate at least one first supply spool 4, from which a so-called outer thread is drawn off.
  • Such work stations 2 furthermore each have a cabling spindle, which is not shown in the figures of the present application for reasons of better clarity, which is driven by a spindle drive.
  • a spindle drive can be a motor that drives the cabling spindle directly, or an indirect drive, for example a belt drive.
  • the cabling spindle carries, as usual, on a stationary bobbin bottom arranged on the cabling spindle, as well as a second supply bobbin, from which a so-called inner thread is drawn overhead, which is fed above the cabling spindle to a cord regulator or balloon thread guide, not shown ,
  • the outer thread is drawn off from the first supply spool 4, which is stored in the creel 3, and is first fed to a thread tension influencing device 9, by means of which the thread tension of the outer thread can be varied or adjusted.
  • the outer thread then circles the cabling spindle, forming a free thread balloon.
  • the cord regulator or balloon thread guide in which the outer thread drawn off from the first supply spool 4 and the inner thread drawn off from the second supply spool are brought together, determines the height of the free thread balloon being formed.
  • this device also referred to as a compensation system, there is the cabling point, in which the outer thread and the inner thread converge.
  • the thread delivery device 10 is arranged above the cabling point, by means of which the twisted or cabled thread is drawn off and fed to a winding device 12 via the pitching lever 11.
  • the winding device 12 has, as usual, a drive roller 13 and a traversing thread guide 14. By means of the traversing thread guide 14, the thread is wound onto a take-up spool 16, which is driven by the drive roller 13 by frictional engagement and held in a bobbin frame 15.
  • FIG. 2 schematically shows an embodiment of the thread delivery device 10 according to the invention, in which the second 20 and third deflection roller 21 are arranged on different sides of a horizontal plane running through the axis of rotation of the laying roller 19.
  • the thread runs in the thread running direction F coming from below over the rotatably mounted first deflection roller 17, is deflected by approximately 90 ° and runs onto the godet 18.
  • the thread is passed around the godet 18 and the laying roller 19 in a plurality of loops, and then from the laying roller 19 via the second deflecting roller 20, which is rotatably arranged at the free end of the pitching lever 11 arranged behind the godet 18, to a third deflecting roller 21 to be led.
  • the third deflection roller 21 is rotatably mounted on a boom 22, which is upstream of the yarn delivery device 10. From the third deflection roller 21, the thread runs into the traversing thread guide 14 at a defined and constant angle of inclination, which winds the thread onto the package 16 with oscillating movements.
  • Figure 3 shows the same embodiment as Figure 2 in the side view, only part of the thread path is another.
  • the thread is fed via the first deflection roller 17, several times via the godet 18 and the laying roller 19 and from the laying roller 19 to the pitch lever 11 or the second deflection roller 20 arranged on the pitch lever 11.
  • the thread is from the front, and not from behind as in Figure 2 shown to the second deflection roller 20 to the third deflection roller 21, so that the thread path has a crossing point in side view.
  • FIG 4 shows an alternative embodiment of the thread delivery device 10 according to the invention in side view.
  • the pitch lever 11 is arranged behind the godet 18 in the installed state of the thread delivery device 10, however the free end of the pitch lever 11 on which the second deflection roller 20 is mounted is arranged upwards in the direction of the package 16.
  • the thread is guided several times around the driven godet 18 and the passive laying roller 19 via the first deflecting roller 17 in order to be fed to the traversing thread guide 14 by the laying roller 19 via the second deflecting roller 20 and further via the third deflecting roller 21.
