Definitions

  • the invention relates to a method for automatically changing the spinning bobbins on a spinning machine which has a large number of spinning positions, each of which contains a drafting device and a spindle which serves to accommodate the spinning bobbins, and a bell which is coaxial with the spindle and spans the spindle.
  • spinning machines with spinning positions corresponding to the type mentioned at the beginning will work at about three times the speed compared to ring spinning machines. This means that the spinning bobbins or bobbins are filled correspondingly much faster, and that the spinning bobbins or bobbins have to be changed correspondingly more frequently.
  • the invention has for its object to provide a method for changing the spinning bobbins on a spinning machine of the type mentioned, which can be carried out quickly and reliably and which can be realized with the help of simple constructions.
  • the spinning bobbins can be changed quickly and safely. Since the thread connection between spinning bobbins and drafting system is initially maintained through the bells and later the thread ends are automatically connected to the empty bobbin tubes, such a method can be easily incorporated into the control program of a spinning machine.
  • the threads are clamped to the spindles when the empty bobbin tubes are placed on them. It is therefore not necessary to provide special thread holding or thread catching devices with which the thread end is fixed.
  • the spindles and the bells each carry out only one of the two movements, i.e. a movement in the axial direction or a movement in the radial direction.
  • a movement in the axial direction is necessary in any case to achieve the winding structure
  • the element carrying out this movement usually the spindle, expediently also performs the axial movement for doffing.
  • the bells radially towards the spindle axes towards the center of the machine. This movement takes place in an area of the spinning machine in which there is sufficient installation space.
  • first spindles and bells are moved apart in the axial direction and then moved apart from each other in the radial direction to such an extent that the bells are held on the holders attached receptacles for spinning bobbins are located in the axial direction above the spindles, then these receptacles and the spindles for receiving the spinning bobbins are moved towards and away from one another again, so that the holders of the bells with empty bobbin sleeves accommodated in second receptacles are moved over the spindles, whereupon the spindles and the second receptacles for transferring the empty bobbin are moved towards and away from each other, after which the bells are brought back over the spindles and bells and spindles are moved into one another in the axial direction, at least the spindles already starting up.
  • a spinning station of a spinning machine which consists of a large number side by side preferably on both sides of the machine in a row arranged spinning positions.
  • Each spinning station contains a drafting system (1) or the like from a roving spool. a roving is fed, which is drawn to the desired yarn count in the drafting device (1).
  • Each spinning station also contains a spindle (3) which is driven by a single motor (4).
  • a spinning bobbin is placed on the spindle (3), on which the spun thread is wound. The spun thread is fed to the spinning bobbin (5) via a bell (2) which is arranged coaxially with the spindle (3) and which engages over the spindle (3) and the bobbin (5) during the normal spinning process.
  • the bell has a guide channel lying in the spindle axis, which has an axial thread inlet.
  • This thread guide channel is followed by a channel piece which is directed essentially radially outwards and usually has an inclination in the take-off direction and which opens into the outer jacket of the bell (2).
  • the thread runs helically on the outer jacket of the bell (2) and leaves it at its lower edge for winding on the spool (5).
  • the bell (2) will normally be freely rotatable so that it is dragged along by the thread running helically on its outer jacket. However, it is also possible to drive and / or brake the bell positively.
  • the coil (5) is wound in a so-called cop assembly on a coil sleeve which is attached to the spindle (3).
  • a corresponding relative movement between the lower edge of the bell (2) and the coil in the axial direction ie a reciprocating movement in the vertical direction, which gradually shifts towards the upper end of the coil.
  • the vertical, back and forth movement is determined by correspondingly raising and lowering the spindle (3) together with its drive motor (4).
  • the thread extending between the bobbin (5) and the bell (2) is fed a thread guide element (6) which, for example, has a V-shaped shape that is open at the bottom and is bent from a wire bracket.
  • This thread guide element (6) is moved obliquely downwards towards the machine center until it comes to lie approximately at the level of the lower end of the sleeve of the bobbin (5), i.e. somewhat above an extension on which an empty coil sleeve (9), which is put on the spindle (3), is later supported in the axial direction.
  • a transport device (7) is assigned to the spinning machine, which consists, for example, of a conveyor belt running along each machine side, which is provided at predetermined intervals with upstanding pins. On this transport element (7) there are initially alternately free pins and pins on which empty bobbin tubes (9) are attached.
  • a transfer device (8) known per se which is known, for example, from ring spinning machines, the full spinning bobbins are gripped in the position according to FIG. 3 and placed on the empty pins of the transport element (7) (FIG. 4).
  • the thread connection between the drafting devices (1) and the spinning bobbins (5) is not interrupted.
  • the thread runs in a kind of thread reserve from the outlet openings located in the sleeves of the bells (2) over the thread guide elements (6) to the upper end of the spools on the transport element (7) (FIG. 4).
  • the transport element (7) then continues by one spindle division, the thread connection likewise not being interrupted.
  • the thread is deflected somewhat by the spindle (3) so that it is at a defined point.
  • the transfer device (8) now takes empty bobbin tubes (9) from the transport element (7) and attaches them to the spindles (3).
  • the thread between the guide element (6) and the upper end of the spinning bobbin (5) is clamped to the spindle (3) by the lower edge of the bobbin tube (9).
  • the thread is then cut near the empty bobbin tube (9) by means of a cutting device (17), which is only shown schematically in FIG. 5, after which the full spinning bobbins (5) can be finally removed (FIG. 5).
  • the drive motor of the spindle (3) is switched on again, while at the same time the thread guide element is moved out of the area of the spinning positions (FIG. 6).
  • the spindle (3) is moved upwards so that it penetrates into the bell (2).
  • the drafting system (1) is also switched on again so that the spinning process runs again.
  • the spun thread then runs again helically on the bell (2) (Fig. 7).
  • the spindle (3) executes the necessary vertical movements according to the cop winding, while the bell (2) only executes a rotational movement to which it is dragged.
  • the individual spinning positions of the spinning machine according to FIGS. 8 to 16 do not differ in principle from the spinning positions of the embodiment according to FIGS. 1 to 7, so that the same reference numerals are chosen for the same elements.
  • the spinning positions there is only one difference in the holders (11) for the bells, on which two additional receptacles (12, 13) are attached, ie two additional ones Recordings (12, 13) for each spinning station.
  • Empty coil sleeves (9) are kept ready in the receptacles (13) adjacent to the bells (2).
  • the spinning process in the position corresponding to FIG. 8 is also ended in this embodiment.
  • the bell (2) and the spindle are moved apart in the axial direction, which is done in the illustrated embodiment by lowering the spindle (3) and its motor (4) (Fig. 9).
  • a thread guide element (14) arranged between the drafting devices (1) and the inlet sides of the bells (2) is now extended transversely to the thread path, so that thread reserves are formed in the area between the drafting devices (1) and the bells (2).
  • Fig. 10 for which the required thread length is subtracted from the full spools (5).
  • the holders (11) of the bells (2) are moved radially to the spindles (3) until the free receptacles (12) are located vertically above the spindles (3) ( Fig. 11). Thread is drawn off the outer jacket of the bell.
  • the next step is to raise the spindle (3) in such a way that the upper end of the bobbin tube is fed to the full spinning bobbin of the receptacle (12).
  • the receptacle (12) consists of gripping elements which engage behind a corresponding inner ring collar of the coil sleeve and which then hold the spinning bobbin (5) when the spindle (3) is lowered.
  • Such gripping elements are known, for example, for holding roving bobbins.
  • the spindles (3) are then lowered again so that they are completely free of the full spools (5) (Fig. 13).
  • the thread present in each case is pulled down over guide elements, for example a ring (18) which can have V-shaped incisions, and over the lower edge of the empty bobbin sleeves (9) provided in the holders (11). brought.
  • the guide element (14) moves back a little so that part of the thread reserve is released.
  • the brackets (11) then move radially to the spindle (3) such that the coil sleeves (9) are located vertically above the spindles (3).
  • the spindles (3) are then moved upwards, so that the empty spool sleeves (9) are placed on the spindles (Fig. 14).
  • the receptacles (13) are also designed in the manner described for the receptacles (12), i.e. by lifting the empty spool sleeves (9) in the receptacles (13), they can be detached from the receptacles (13) and are then carried along by the spindles.
  • the empty bobbin tubes (9) are taken over by the spindles (FIG. 14), the threads are clamped between the spindles and the lower edges of the empty bobbin tubes.
  • connection to the full spinning bobbins (5) hanging in the brackets (11) is then separated, after which the spindle with the empty bobbin tubes are moved down.
  • the holders (11) are moved radially to the spindle (3) in their original position (Fig. 8), so that the spindles (3) with the empty coil sleeves (9) are under the bells (2) (Fig. 15 ).
  • the drive of the spindles (3) is switched on, while at the same time the thread guide element (14) is moved back out of the thread path (FIG. 15), so that the thread reserve dissolves.
  • the spindle (3) with the empty coil sleeve (9) is moved upwards so that it penetrates into the bell (2).
  • the drafting device (1) is switched on again, so that the spinning process is resumed (FIG. 16).
