Description

  The present invention relates to a frame opening device for a package frame with two frame arms and a textile machine for manufacturing a winding package with such a frame opening device. Furthermore, the present invention relates to a method for opening a package frame having two frame arms.

  As a textile machine for manufacturing a winding package, not only a winding machine but also a spinning machine such as a rotor spinning machine is available.

  In a working unit of a winder, in particular with a winding device, a spinning cup with a relatively small amount of yarn material is usually used to wind up the large volume required in a textile machine, such as a loom, placed downstream in the production process. Rolled back into the package.

  In the working unit of the rotor spinning machine, the sliver accommodated in the can is spun into a single yarn and wound into a winding package. Therefore, such a work unit has a spinning device in addition to the winding device.

  For example, the winding package is placed on a driving roller and is driven by friction by the driving roller. If the drive roller is configured as a grooved roller, the drive roller is additionally responsible for guiding the yarn to be wound. On the other hand, when a grooveless drum is used as the drive roller, the yarn guide is guaranteed by a separate yarn guide, for example a finger yarn guide. Alternatively, the drive can be incorporated into the frame arm of the package frame.

  In order to open the package frame, i.e. to remove the winding package or to mount the winding tube, the pivotally supported frame arm is often mechanically moved by a lever. In connection with the drive device incorporated in the frame arm, an opening device is also known which is pneumatically controlled and moves the winding tube holder axially to the open position against the action of the load means.

  DE-A 2157304 B (DE 21 57 304 B) describes, for example, a package frame having a package frame arm that is pivotably supported, and this package frame arm is connected via a corresponding rod. It can be mechanically driven from the middle position in the direction of “package frame opening”.

  EP 1184320 (EP 1 184 320 B1) discloses a winding device which is used as a braking device for traverse packages in addition to driving. Has a drive unit incorporated in the. This drive device is supported in a slide bush which is pneumatically movable and is spring loaded. The slide bush is provided with a winding tube receiving tray, and the winding tube receiving tray can be moved outward by the movement of the slide bush, thereby releasing the winding tube or the winding package. In order to allow the package frame to be opened manually and to move the spring-loaded slide bush, a counter-receptor into which a corresponding tool can be inserted is provided.

  German Offenlegungsschrift DE 10 0079 49 A (DE 100 07 949 A1) discloses a package frame having a drive device incorporating a braking device. The drive device is supported so as to be movable in the axial direction in the bearing housing of the package frame. In this case, the bearing housing has a guide portion, and a control protrusion connected to the drive device is provided in the guide portion. The part slides. Furthermore, this control protrusion is connected to a pneumatic cylinder. A double-acting pneumatic cylinder can selectively drive one of the winding tube receiving trays as well as drive a braking device that stops the traversing package, so that the winding tube or the traversing package Can be mounted or removed. That is, according to the driving of the pneumatic cylinder, the driving device is moved in the direction of the center of the package and the braking device is operated at that time, or the driving device is moved together with the winding tube receiving tray to the outside of the package frame.

  Accordingly, the first aspect of the present invention relates to a frame opening device for a package frame having two frame arms. In this case, each frame arm is provided with a winding tube holding portion, and both winding tube holding portions are The winding tube or the winding package is disposed between the two winding tube holding portions so as to be rotatably supported.

  The proposed frame opening device includes an operating device, a closing mechanism connected to the operating device, and a stopper surface. In this case, the package frame is limited and supported by a movable frame. The stopper surface is formed by the surface of the stationary part of the package frame, and the corresponding surface of the movable frame arm can come into contact with this surface.

  Such a configuration ensures reliable opening and closing of the package frame. At this time, the take-up package is removed until, for example, the service assembly allows the winding tube to be attached to or removed from the package frame, or until the winding tube is manually attached. The operating device can be driven and controlled so that the package frame remains in the open position until it is released. By actuating the operating device, the closing mechanism connected to the operating device is driven and controlled, so that the movable, limited and rotatably supported frame arm is pivoted outward. When the package frame is closed, the stopper surface as part of the stationary package frame ensures that the movable frame arm having a surface corresponding to the stopper surface always occupies a reliable and defined position in the closed state.

  A frame opening device can be incorporated into each package frame without depending on the type of drive for the winding package. In the case of a direct drive in which the drive device is incorporated in one of the frame arms, the frame opening device has the additional advantage of disconnecting the opening mechanism from the drive mechanism. The driving device torque does not act on the frame opening device, and the driving mechanism does not need to realize the opening operation at the same time.

  It is reasonable that the frame opening device can be combined with a lever or the like, and the package frame can be manually opened even when drive control of the operating device does not occur.

  In a particularly preferred configuration, a frame opening device is incorporated in the stationary part of the package frame.

  Such an arrangement of the frame opening device is particularly advantageous with regard to the division or required space of the individual work units. Of course, it is also conceivable to arrange the frame opening device in the movable frame arm within the frame of the present invention, but this involves an unfavorable dimensioning of the movable frame arm.

  The incorporation into a frame arm or package frame is particularly advantageous. This is because the components of the frame opening device are thereby protected simultaneously from dirt and flying debris.

  In a preferred configuration, the operating device is constituted by a pneumatic cylinder.

  A single-acting pneumatic cylinder is sufficient to ensure that the package frame is driven and controlled as needed.This single-acting pneumatic cylinder not only provides easy drive control but also reduces air consumption. Guarantees a fixed position at the time of reduction and pressure drop.

  At this time, the closing force of the package frame or the frame arm is realized through the return force of the pneumatic cylinder. For example, when the valve in front of the pneumatic cylinder releases the pneumatic cylinder's compressed air supply, the package frame is opened, so you can install an empty winding tube, or manually or automatically It can be taken out. When the compressed air supply is shut off to the pneumatic cylinder, the package frame closes and the winding / winding package is securely clamped between the winding tube holders. Such a switching ensures that the wound tube / windup package cannot fall out of the package frame, for example during the winding process or at the start-up of the textile machine, even if the compressed air disappears unexpectedly.

  In this case, other operating devices, such as, for example, an electrically driven adjustment cylinder, are also conceivable within the framework of the invention. In principle, any device that can establish and control the closure mechanism can be used.

  It is preferable that the wound tube holding portion of the movable frame arm is supported in a spring-elastic manner in the axial direction.

  In order to ensure that the movable frame arm is always pressed against the stopper at the same position in the closed state, the winding tube holding part is supported so as to be movable in the axial direction. Thus, the movable frame arm can compensate for slight length differences in the windings, in which case the tolerance for such length differences in the windings is typically ± 2 mm within a lot. As a result, the movable frame arm is always properly oriented with respect to the stationary frame arm even if the length of the winding tube varies.

  It is preferable that the winding tube holding portion is supported in the steel sleeve, and the steel sleeve can be positioned at various positions in the movable frame arm.

  With such a configuration, a difference in length of the wound tube, for example, 10 mm or more can be compensated. Such a difference in length occurs in winding tubes with different lots. At this time, the steel sleeve is supported in the accommodating portion of the movable frame arm, and the steel sleeve can be positioned in the accommodating portion at various depths.

  Positioning in the housing of the steel sleeve is done manually before the start of the winding process or by installing the first winding of a new lot.

  At this time, such a support of the steel sleeve can be replaced without depending on the winding tube holding part supported in a spring-elastic manner in the axial direction, but it is particularly preferable to combine both supports. . Such a combination allows for secure retention of the winding / winding package while maximizing the flexibility of the package frame.

  A further aspect of the invention relates to a textile machine for producing a winding package, comprising at least one winding device, the textile machine comprising a package frame having two frame arms. In this case, each frame arm is provided with a winding tube holding portion, and both winding tube holding portions are arranged so that the winding tube or the winding package can be rotatably supported between the both winding tube holding portions. ing.

  The textile machine for producing this proposed winding package is characterized in that it has at least one frame opening device configured as claimed in any one of claims 1-5.

  Such a textile machine can flexibly handle different lots and different types of winding tubes without the need for laborious rearrangements or different package frames. Only the steel sleeve in which the winding tube holding portion supported in an elastic manner in the axial direction is arranged may be adjusted according to the length of each winding tube at the start of a new lot.

  At the same time, the opening and closing of the package frame can be automated reliably and inexpensively. At this time, the frame opening device compensates for the tolerance in the winding tube length, and always ensures the central positioning of the movable frame arm.

  A further aspect of the present invention relates to a method for opening a package frame having two frame arms. In this case, each frame arm is provided with a winding tube holding portion, and both winding tube holding portions are provided with both of them. It arrange | positions so that a winding tube or a winding package may be rotatably supported between winding tube holding | maintenance parts.

  In the first step, the operating device is driven to open the package frame, in the second step, the closing mechanism is operated by the operating device, and in the third step, the movable frame arm is wound around the package frame. It has been proposed to swivel to allow tube installation or removal of a clamped winding or winding package from the package frame.

  Such a method allows loading and unloading of the winding tube and winding package without the need for manual intervention. At this time, it is sufficiently conceivable that the package frame remains in the open position until mounting or removal is performed manually.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic view of a package frame with a frame opening device according to the present invention in an open position; FIG. 1 schematically shows a package frame with a frame opening device according to the invention in a closed position; FIG. FIG. 2 schematically shows a package frame with an alternatively arranged frame opening device according to the invention in an open position; It is the figure which showed the package frame schematically. It is the figure which showed the package frame schematically.

  In FIG. 1A, the package frame 1 is shown significantly simplified and schematically. The package frame 1 includes an immovable portion 2 having one frame arm and a movable frame arm 3 supported by a pivot shaft 7 so as to be rotatably supported. In this embodiment, a direct drive 4 is incorporated in the package frame 1. The direct drive 4 is arranged so that one winding tube holding part 5 is connected to the direct drive 4.

  Since the other winding tube holder 5 is positioned on the movable frame arm 3, the winding tube 6 is rotatably supported between the winding tube holders 5 for manufacturing the winding package. At this time, the wound tube holding part 5 is supported in a spring-elastic manner in the axial direction and is disposed in the steel sleeve 14.

  A frame opening device 13 is disposed in the movable frame arm 3. At this time, the frame opening device 13 includes a closing mechanism 8 and an operating device (in the present embodiment, configured as a pneumatic cylinder 9). A stopper surface 11 is formed by the surface of the stationary part 2 of the package frame 1 and corresponds to the surface 12 of the movable frame arm 3.

  In order to open the package frame 1 and to turn the movable frame arm 3, compressed air is supplied to the pneumatic cylinder 9 and the piston rod 10 of the pneumatic cylinder 9 advances. The closing mechanism 8 connected to the pneumatic cylinder 9 moves, so that the movable frame arm 3 can be swiveled and the winding tube 6 can be mounted.

  After the winding tube 6 is mounted, the pressure supply to the pneumatic cylinder 9 is interrupted. FIG. 1B shows the package frame 1 in the closed position. The piston rod 10 is retracted into the pneumatic cylinder 9, and the closing mechanism 8 is driven and controlled accordingly. The surface 12 of the movable frame arm 3 is in contact with the stopper surface 11 of the non-moving portion 2, and the winding tube 6 is fastened so as to be rotatable between both winding tube holding portions 5.

  FIG. 2 shows an alternative configuration of the frame opening device 13. In this example, the pneumatic cylinder 9 and the closing mechanism 8 are arranged in the stationary part 2 of the package frame 1. By supplying compressed air to the pneumatic cylinder 9, the piston rod 10 advances, and the closing mechanism 8 is driven and controlled so that the package frame 1 or the movable frame arm 3 turns to the open position.

  3A and 3B show a part of the package frame 1, in particular the movable frame arm 3. As described above, the movable frame arm 3 is supported via the pivot shaft 7 so as to be rotatable. The stopper surface 11 is formed by the surface of the stationary part 2. The surface 12 of the movable frame arm 3 corresponds to the stopper surface 11. In this embodiment, the surface 12 is divided into two parts.

  When the package frame 1 is closed, the movable frame arm pivots in the direction of the wound tube 6 until the surface 12 contacts the stopper surface 11. In this way, a closed and unchanging closed position of the package frame 1 is guaranteed.

  Since the wound tube holding portion 5 is supported in a spring-elastic manner in the axial direction, a slight difference in length of the wound tube 6 to be tightened can be compensated. The winding tube holding part 5, which is spring-elastically supported in the axial direction, is supported in the steel sleeve 14 so that a larger difference in length can be compensated. The steel sleeve 14 is supported in the accommodating portion 16 of the movable frame arm 3 so as to be fixed by the attaching means 15 (in this case, a screw). Since the steel sleeve 14 can be positioned in the accommodating portion 16 of the movable frame arm 3 at various depths, the winding tubes 6 of various lots having different lengths can be installed in the same package without recombination. Can be processed in frame 1.
