Definitions

  • the present invention relates to a method for the automatic removal of the full bobbins and the insertion of the empty sleeves from or onto the spindles of one with at least one row of spindles and above each spindle rotatably mounted in a wing head, consisting of two wing arms and a wing yoke existing wings equipped Vor ⁇ spinning machine and a device for performing the method.
  • Roughing machines of this type which are also called flyers, are used in the spinning process for staple fibers in the last stage of production. They are used to manufacture a warpable roving which is wound onto a large-sized bobbin and is used as a template for the next processing machine, usually the spinning machine. Due to the tendency in recent years to manufacture ever larger and thus heavier spools, the operation of manually changing the full spools against empty tubes has become increasingly difficult for the operating personnel, so that several attempts have already been made by adapting the training of the working organs, and in particular the spindles and the wings, to create the conditions for mechanizing the operation.
  • each wing is mounted and driven in a stationary upper support and carries a mandrel for the sleeve, and in which a vertically displaceably guided bobbin holder is a di shape of a spindle with a short arbor is lowered
  • the removal operation ensures that the arbor of the wing is pulled out of the coil sleeve so that the bobbin only rests on the short arbor of the spindle.
  • This device By lifting the bobbin in the working position, the sleeve is brought into the correct position with respect to the wing, which means that the replacement operation is to be regarded as finished.
  • This device in which corresponding organs are provided for the transverse displacement of the bobbins and the sleeves, implements the mechanized exchange of the bobbins on a prespinning machine.
  • the coil carrier must be able to be lowered by more than the entire sleeve length or outside the normal stroke of the coil carrier. This results in a high, unfavorable position of the working elements of the machine during normal operation, which entails operational disadvantages.
  • the "cross pull" of the bobbins means that the space in front of the machine is blocked, namely before the replacement operation by the prepared sleeves and after the operation by the bobbins.
  • the necessary working elements which are in the form of fork-shaped grippers that can be pivoted about a vertical axis, make operating the machine more difficult.
  • lowerable spindles and fixed wings are also provided with an arbor.
  • the bobbins and the sleeves are no longer removed or brought in from the spindle, as in the previously mentioned example, transversely to the spindle and to the longitudinal axis of the machine, but transversely to the spindle, but parallel to the longitudinal axis of the machine.
  • a conveyor belt is provided above the bobbin, on which the sleeve feet of the drawn-off bobbins come to rest after the mandrels of the spindles have been lowered even further.
  • the full bobbins are thus removed in a vertical position, transverse to the spindle axis, in the longitudinal direction of the roving machine; the empty sleeves are then positioned in the same way.
  • This device also has the operational disadvantages mentioned above due to the length of the lowering movement of the coil carrier for the first-mentioned device. On the other hand, it does not take up additional space in front of the machine. However, due to the presence of the transport
  • a wing in the case of roving machines, which with. its lower part is attached to a race and has a free wing head.
  • This wing is further attached to the race, the diameter of which is equal to the wing width, about a 5-axis lying at right angles to its axis of rotation, and elastic form-locking elements which snap into the wing are provided between the wing and the race.
  • the wing is now turned over or swiveled to the side, which is done by overcoming the fastening force generated by the elastic form-locking elements between the wing and the race.
  • the device for carrying out the method according to the invention should be further robust and reliable and require a minimum of maintenance work.
  • This object is achieved in a method for the automatic removal of the full bobbins and the insertion of the empty sleeves from or onto the spindles of a wing consisting of at least one row of spindles and above each spindle rotatably in a wing head and consisting of two wing arms and a wing yoke equipped roving machine is solved by using the following process steps:
  • the roving machine for carrying out the method according to the invention has the following features:
  • a pulling and attaching element which can be moved vertically up and down, has a gripper for the full spool and a sleeve carrier for the empty sleeve of each spindle,
  • FIG. 1 shows a side view of a roving machine according to the invention during a phase of the pulling-off and attaching operation.
  • FIG. 2 shows a cross section through a double-row roving machine during the pulling-off operation of the full bobbins, for reasons of simplicity only the elements directly participating in the exchange operation being shown.
  • Fig. 4 shows a detail of a sleeve carrier for the empty sleeves according to a preferred embodiment of the invention.
  • Fig. 5 shows a detail of Fig. 4 cut along the line VV of Fig. 4.
  • Fig. 6 shows a particularly advantageous embodiment of the trough carrying the wings.
  • FIG. 1 shows a schematic representation of a roving machine according to the invention, only the elements necessary for understanding the invention being shown for reasons of simplicity.
  • Such a machine consists of at least one row of spindles, onto which the sleeves for winding the roving as spools 2 are attached, and associated blades 1, which are the same in operation.

  • the machine On the stationary frame of the machine there is also a known one, consisting of a series of cylinders (only one of which is shown and with the reference number 11) designated) and corresponding pressure roller formed drafting system 12 attached. Furthermore, the machine has a feed gate, not shown, which is arranged above or behind the drafting system and by means of which the textile slivers are fed to each spinning station.

  • each locker and the associated wing 1 rotate coaxially, ie the wing is arranged in the vertical position above the spindle. Since roving 14 supplied by the drafting device 12 is passed through the high axis 10 of the wing head 6, one reaches the wing arms 3, 4 (for example wing arm 4 according to FIG. 6) and is pressed onto the surface of the corresponding bobbin 2 by means of a press finger (not shown) on which it is wound.

  • pivot axis z intersects both wing arms 4 and 4 symmetrically, which is achieved in that, before the wing 1 is pivoted, these are put down in a position in which each wing yoke 5 (see FIG. 1) is in one comes to lie perpendicular to the pivoting plane.
  • the wing 1 in its lower part, e.g. through the ring 27, additionally articulated in a sleeve that rotates centrally to the spindle, the pivoting of the wing 1 about this (not shown) joint axis must of course take place, with which the wing head 6 must then describe an arc when pivoting. 2, the path described by the highest point of the carrier 7 when pivoting from position A to position B is shown in dash-dot lines. 0
