Definitions

  • the present invention relates to a control device for driving and stopping an open-end spinning element, with a pivotable control lever, which can assume a production position, a piecing position and a braking position, in the production position a first drive running at production speed, in the piecing position one versus the first drive running at a lower speed, second drive and in the braking position a brake acts on the open-end spinning element, and with stops to hold the control lever in one of the three positions.
  • a pivotable control lever which can assume three different working positions (WO 86/03792).
  • the control lever brings into effect a first drive running at production speed, in the piecing position a drive running at a lower speed than the first drive, and a brake in the braking position.
  • Stops are assigned to the control lever, which hold the control lever in one of the three positions. At least the stops that hold the control lever in the production position and in the piecing position are controllable.
  • the control takes place with the help of an electromagnet, which can be controlled via a switching device which also controls the fiber feed to the spinning device.
  • the switching device is followed by a control device.
  • a control device is complex, in particular if the response times for reactivating the fiber feed and actuating the stop vary due to different materials. In addition, such an adjustment can only be carried out by trained personnel.
  • the object of the present invention is therefore to design a device of the type mentioned in such a way that any control of the control lever and thus of the spinning element is made possible in a simple manner even by untrained personnel.
  • This object is achieved in a generic device in that at least the stops defining the production and the piecing position of the control lever are assigned a common control element which can be moved back and forth between at least two switching positions in the direction of movement of the free end of the control lever.
  • the stops for the control lever are actuated, whereby the mobility of the control element in the direction of the free end of the control lever ensures that depending on the position of the control element, once the stop for the production position of the control lever and the other time the stop for Firing position of the control lever is effective or disabled.
  • the control lever is controlled completely independently of the control of other units, e.g. switching on the fiber feed, switching on the thread monitor, etc., so that the desired actuation of the control lever can even be achieved manually without complicated changes.
  • a stop element which, depending on the switching position of the control element, forms the stop for fixing the production position or the stop for fixing the piecing position of the control lever. If necessary, this stop element can also determine the braking position of the control lever.
  • the stop element is expediently an integral part of the control element.
  • the control element therefore has the task of determining the respective working position of the control lever with its stop element.
  • the control element for releasing the control lever and for determining the working position of the control lever can also be moved transversely to the direction of movement of the control lever in addition to in the direction of movement of the free end of the control lever. This can be effected, for example, by the control element being displaceable in a backdrop.
  • the control element is pivotally mounted for movement transverse to the direction of movement of the free end of the control lever.
  • control element with the stop can in principle also be moved parallel to the pivot axis of the control lever in order to release the control lever, but it is of particular advantage in the interest of a particularly robust design of the subject of the invention if the control element having the stop element is movable transversely to the pivot axis of the control lever.
  • a substantially U-shaped link guide is provided, the ends of which extend transversely to the direction of movement of the free end of the control lever and, together with a stop bolt engaging in the link guide, define two switching positions of the control element, so that the control element is in its two switching positions is securely fixed.
  • the U-shaped link guide is provided on the control element.
  • the control element is pivotally mounted on the control lever.
  • the control element is expediently designed as a two-armed lever, of which the first arm has the link guide and the second arm extends essentially parallel to the control lever and is acted upon by a spring supported on the control lever so that the stop pin in one of the Ends of the scenery guide remains.
  • it is only necessary to pivot the two-armed lever relative to the control lever, so that the stop pin in the link guide can get from one end to another end.
  • control lever has an extension which extends beyond the bearing point of the control element and to which the second arm of the control element extends essentially parallel.
  • the link has an E-shape instead of a U-shape, the three free ends of which are E-shaped Guide link extend transversely to the direction of movement of the free end of the control lever.
  • the control element is assigned two pivot axes, which can optionally be brought into effect, one pivot axis being assigned to the stop element and the other pivot axis being formed by a stop defining at least one switching position of the control element.
  • the control element In order to release the control lever or to bring it into engagement behind the stop element, the control element is pivoted about the pivot axis, which is formed by a stop defining one of the switching positions of the control element. Despite the release or retention of the control lever, the control element thus remains in the previous switching position.
  • control element is now to assume its other switching position, the control element is pivoted about the pivot axis which is assigned to the stop element. In this way, the control element is released from the stop fixing its switching position and can be brought into its other switching position.
  • control element is pivotally mounted, it could happen due to gravity that the control element is pivoted so far that the control lever cannot be returned to its production or piecing position. To prevent this, the control element is expediently assigned a stop limiting its movement in the direction of the control lever.
  • the control element has to perform movements in three different directions.
  • the stop element integrated in the control element is assigned a stop element which is arranged on the free end of the control lever and is movable transversely to the direction of movement of the free end of the control lever is in turn associated with a drive element that is movable relative to the control element.
  • the stop element which is movably mounted in the control lever in this way, can be moved in this way by the drive element movable in relation to the control element such that it comes out of the effective range of the stop element integrated in the control element, so that the control lever moves into its other working position can.
  • the drive element is expediently mounted on the control element in such a way that it can be moved relative to the latter.
  • the drive element is movable in the direction of movement of the control element and has a run-up ramp in order to be able to disengage the stop element which is movably arranged on the free end of the control lever from the stop element integrated in the control element.
  • the stop element does not necessarily have to be integrated in the control element.
  • the stop element cooperating with the control lever is movably mounted relative to the control element, this stop element advantageously being part of a swivel lever.
  • control element is assigned a stop which can be moved transversely to its direction of movement.
  • the movements of the control lever can be achieved in an advantageous manner in that the control lever, the control element, the stop movable relative to the control element and the drive element movable relative to the control element for the stop element arranged movably at the free end of the control lever or the stop element movable relative to the control element a drive surface is assigned, which can be acted upon by linearly movable actuating means.
  • Such a design is not only suitable for manual control of the control lever, but can also be used just as advantageously for automatic control of the control lever and thus of the spinning element.
  • control element is assigned a guide which, when the control element moves in the direction of movement of the free end of the Control cross movements limited to this.
  • the control lever is generally acted upon by a spring in the direction of movement which corresponds to the movement of the control lever into the braking position.
  • the control element is expediently acted upon by a spring opposite to the direction of action of the control lever.
  • the spring can be adjustable, for example in that the spring is assigned a stepless adjustment device.
  • the spring assigned to the control lever is made stronger than the spring assigned to the control element. In this way, the control lever always receives a force component opposite to the direction of action of the control element, even when it is additionally acted upon by the stop element and the control element.
  • control lever can be assigned to a spinning station in any way.
  • control element is preferably mounted in a cover for the spinning station.
  • the control lever and the control element can, if necessary, also be controllable by such a movable piecing device. In this way it is possible to initially provide a device of the type mentioned for manual operation and to retrofit the spinning machine later with a piecing device. Even if such a retrofit has been carried out, the control lever can still be controlled manually.
  • the switching position of the control element which determines the piecing position of the control lever can be determined by the stroke of a control means provided on the movable piecing device. An additional stop for fixing this piecing position can then be omitted.
  • the stops are acted upon elastically in the direction of the control lever and are supported with their ends facing away from the control lever on run-up ramps of the control element, of which the run-up ramp, which is assigned to the stop defining the production position of the control lever, after passing through one larger switching path is effective than the run-up ramp which is assigned to the stop defining the piecing position of the control lever.
  • FIGS. 1 to 3 show a spinning station of an open-end spinning machine with a large number of identical spinning stations of the same type, arranged side by side, each with a spinning element.

  • the arm 201 with the main pressure roller 21 is assigned a compression spring 23 which, when the switch lever 20 is released with the main pressure roller 21, normally holds the main drive belt 10 in contact with the shaft 1 of the spinning element (not shown).

  • This position is referred to as production position I, since in this position of the control lever 4 the main pressure roller 21 holds the main drive belt 10 in contact with the shaft 1 of the spinning element, not shown, so that the spinning element is driven at a high speed, namely the production rotational speed.
  • control lever 4 can nevertheless assume a further position, the braking position, in which the brake 3 is brought to act on the shaft 1 of the spinning element, not shown.

  • the switching lever 20 is pivoted so far via the driver 32 and the stop 203 that the main pressure roller 21 does not hold the main drive belt 10 in contact with the shaft 1, but that the auxiliary pressure roller 22 does not yet hold the auxiliary drive belt 11 for contact with the shaft 1 of the spinning element.
  • a switch can be provided on the cover 5 for actuating a cleaning device for the spinning element arranged in the cover, this switch being actuated by a relative movement of the control lever 4 relative to the cover 5. Cleaning of the spinning element is thus carried out simultaneously with the braking of the spinning element.

  • control lever 4 is first returned from the position shown in FIG. 2 to the position shown in FIG. 1, in which the control lever 4 is held by the stop 6 by latching the counter-stop 41 into the recess 61, since that Control element 7 is always pressed down against the control lever 4 due to the action of the spring 73.

Abstract

Un levier pivotable de commande (4) que l'on peut mettre sur trois positions de travail sert à commander un élément de filature open end. Dans une première position de production, le levier de commande (4) amène un premier entraînement tournant à la vitesse de production à agir sur l'élément de filature open end. Dans la position de freinage, le levier de commande (4) amène un frein (3) à agir sur l'élément de filature, et dans la position de démarrage du filetage, le levier de commande (4) amène un deuxième entraînement tournant à une vitesse inférieure à celle du premier entraînement à agir sur l'élément de filature open end. Un élément commun (7) de commande relié au moins aux butées (6) déterminant les positions du levier de commande (4) de production et de démarrage du filetage peut se déplacer en avant et en arrière entre aux moins deux positions de commutation (I, II) dans le sens du déplacement de l'extrémité libre (42) du levier de commande (4). Un élément d'arrêt (60) relié à l'élément de commande (7) forme la butée (6) qui détermine au moins la position de production ou de démarrage du levier de commande (4) selon la position de commutation (I, II) de l'élément de commande (7). L'élément d'arrêt (60) forme une partie intégrante de l'élément de commande (7). L'élément de commande (7) peut se déplacer non seulement dans le sens de déplacement (P1) de l'extrémité libre (42) du levier de commande (4), mais aussi transversalement au sens de déplacement (P1) de l'extrémité libre (42) du levier de commande (4).
