Definitions

  • the invention relates to an external gripper for gripping fiber yarn carriers on spinning or twisting machines, with an deliverable clamping element and a stationary clamping element, which comprises a holder, which has a pocket-shaped receptacle, and a releasable clamping element received in the holder, the clamping surfaces of which center to a centering axis of a spindle or a pin are aligned to receive the fiber yarn carrier.
  • a cop pulling device is known (DE-AS 25 42 222), in which a stationary clamping element consists of a ring, the diameter of which is larger than the head sleeve diameter.
  • a piston which can be moved radially in the direction of the axis of symmetry of the ring and which has a frontally arranged clamping surface forms the deliverable clamping element.
  • the ring In the working position, the ring is guided over the bobbin until the desired clamping position is reached.
  • the cop is then clamped by moving the piston between its clamping surface and the inside of the ring opposite the piston.
  • a disk-shaped gripper device in which two gripper elements are integrated.
  • Each gripper element has a vertical recess provided, which is approximately circular and on the circumference of which two stationary clamping elements are arranged offset by 120 °.
  • the stationary clamping elements are assigned an adjustable clamping element which is offset by a further 120 ° and provided with a clamping surface and which is part of a pneumatically adjustable piston.
  • the invention has for its object to provide an external gripper for gripping fiber yarn carriers on spinning or twisting machines, which allows sufficient centering of fiber yarn carriers with different diameters with little technical effort.
  • the object is achieved in that a set of interchangeable releasable clamping elements is provided, the fastening means assigned to the holder are in each case the same and the clamping surfaces are at different distances from the centering axis.
  • an external gripper which makes it possible to clamp different nominal diameter ranges of fiber yarn carriers with an external gripper and to hold them in a centered position by assigning a corresponding detachable element to a specific nominal diameter range, which can be easily replaced in the holder.
  • the releasable elements are made of plastic, which enables inexpensive production of the releasable elements, for example by means of an injection molding process.
  • the detachable elements can be provided in a corresponding color.
  • the releasable element of the stationary clamping element has two flat clamping surfaces inclined to one another, whereby an exact centering of the fiber yarn carriers to be clamped is ensured.
  • the holder of the stationary clamping element has a pocket-shaped receptacle for the releasable clamping elements.
  • the releasable element has an extension protruding from the holder, whereby identification of the releasable clamping element used in the external gripper, e.g. by means of optical sensors, even in the operating state.
  • the releasable clamping elements of a nominal diameter range are of the same color to one another and differ from the releasable clamping elements of another nominal diameter range by a different color. This provides an uncomplicated possibility of clearly identifying the releasable clamping elements and assigning them to a specific nominal diameter range.
  • the external gripper according to the invention shown in the figures has a stationary and an deliverable clamping element (15), which can hold a fiber yarn carrier (1), in the exemplary embodiment a sleeve, between them and hold them in a clamping manner.
  • the stationary clamping element is formed from a holder (2) integrated in the external gripper and a releasable clamping element (3).
  • the holder (2) has a pocket-shaped receptacle (4) into which the releasable clamping element (3), as shown in FIG. 1, is inserted.
  • the holder-side contour of the releasable clamping element (3) corresponds to the contour of the pocket-shaped receptacle (4).
  • the releasable clamping element (3) On the side facing the fiber yarn carrier (1), the releasable clamping element (3) has two flat clamping surfaces (5) inclined to one another, which form an opening angle ( ⁇ ).
  • the clamping surfaces (5) of the releasable clamping element (3) are arranged symmetrically and parallel to the centering axis (6) of a spindle or a pin (not shown) for receiving the fiber yarn carrier (1).
  • the pocket-shaped receptacle (4) has a vertical rib (7) on each of its side faces.
  • the releasable clamping element (3) has a stop (8) on both sides.
  • a stop (9) in the holder (2) serves to position the releasable clamping element (3) in the horizontal plane.
  • one entry slope (10) which adjoins the lower ends of the clamping surfaces (5) and is inclined in the direction of the receptacle (4), serves both for centering the fiber yarn carrier (1) and for guiding against the clamping surfaces (5).
  • this At the holder-side end of the inlet slope (10), this has a locking lug (11).
  • the pocket-shaped receptacle (4) has a horizontal rib (12) which extends through the receptacle (4).
  • the visible in the drawing profile-like design of the detachable Clamping element (3) makes it elastically deformable in the vertical direction, so that the locking lug (11) can engage behind the rib (12). This prevents the releasable clamping element (3) locked in the holder (2) from sliding out.
  • An extension (13) shown in FIG. 3 and protruding from the holder (1) serves to identify the releasable clamping element (3) locked in the external gripper.
  • a clamping element (15) which is pneumatically adjustable in the direction of the axis of symmetry (14) of the releasable clamping element (3) is arranged opposite the stationary clamping element in such a way that it can be moved back into a starting position which allows the taking up of fiber yarn carriers (1) with a maximum diameter (see Fig. 3).
  • a certain infeed area must still be present in order to ensure that the outer gripper runs securely onto the fiber thread carrier (1).
  • FIGS. 1 and 3 relate to a releasable clamping element (3) for the nominal diameter range 26 to 28 mm.
  • An opening angle ( ⁇ ) of 90 ° was chosen for the arrangement of the prismatic surfaces (5).
  • the design-related fixed distance between the centering axis (6) and the pocket base (16) is 34 mm in the exemplary embodiment.
  • clamping elements (3) In order to clamp fiber thread carriers (1) of different nominal diameter ranges with a single external gripper, various types of releasable clamping elements (3) can be inserted into the holder (2).
  • the clamping elements (3) differ either by different distances (a) between the intersection of the clamping surfaces (5) and the pocket base (16) of the receptacle (4) or due to different opening angles ( ⁇ ).
  • a variation between the distance (a) and the opening angle ( ⁇ ) is also within the scope of the invention.
  • a reduction in the distance (a) with a constant opening angle ( ⁇ ) results in an enlargement of the clampable nominal diameter range.
  • a corresponding increase in the distance (a) means a reduction in the clampable nominal diameter range.
  • An increase in the opening angle ( ⁇ ) with a constant distance (a) results in an increase in the clampable nominal diameter range.
  • a corresponding reduction in the distance (a) means a reduction in the clampable nominal diameter range.
  • the variation of the position of the clamping surfaces (5) can be carried out on the holder side in such a way that reaching behind the rib (7) is still ensured by the stop (8) and the fiber yarn carrier (1) in the clamping position on the clamping surfaces (5) and not on the Ribs (7) abuts.
  • FIG. 2 shows an exemplary embodiment for receiving fiber yarn carriers (1) with a maximum diameter.
  • the in Fig. 2 outer gripper differs from the outer gripper according to FIGS. 1 and 3 essentially in that the releasable clamping element (3 ') has clamping surfaces (5') which are at a greater distance from the centering axis (6) (not shown) ) Have a spindle as the clamping surfaces (5) of the releasable clamping element (3). Due to this increased distance between the clamping surfaces, the outer gripper fiber yarn carrier (1) with max. Grip diameter without the center axis of the gripper migrating with respect to the centering axis (6) of the spindle.
  • the releasable clamping element (3 ') is fixed on the holder (2) in principle in the same way as in the embodiment shown in FIG. 1.
  • the external gripper In the operating state, the external gripper is guided over the end of the fiber yarn carrier (1, 1 ')).
  • the inlet slope (10) is placed on the edge of the fiber yarn carrier (1, 1 '), whereby it is centered and guided against the surfaces (5, 5').
  • the deliverable clamping element (15) is then fed in and thereby the fiber yarn carrier (1, 1 ')) is clamped, as a result of which it can be removed from the spindle (not shown in the drawing) or placed on a pin.
