Definitions

  • ABSTRACT A sleeve chuck in a textile winding device in which the winding shaft, adapted to hold or grip a bobbin or core sleeve, is made up of an inner shaft means freely rotatable within an outer cage means provided with openings to receive individual gripping elements in cammed engagement with the shaft means and also including spring means interconnecting the shaft and cage means to resiliently urge the gripping elements radially outwardly of the cage means.
  • This invention generally relates to sleeve chucks, es-
  • the invention is concerned with such winding devices which are driven by a drive roller applied to the bobbin or winding, especially at high winding speeds with use of the so-called free-running or freewheeling principle.
  • a number of different chuck constructions are known. They have in common as one essential feature that they are often operated through theaxis-of a hollow winding shaft, for example by a connecting rod arranged longitudinally and slidably in the axis of the winding shaft or by means of feeding in a fluid hydraulie or pneumatic pressure medium through the hollow shaft bore. All of these constructions possess considerable disadvantages.
  • Pneumatic or hydraulic expansible chuck systems in which there is provided an inflatable tube between the winding shaft and a core sleeve, has the disadvantage of relatively poor centering, which is most unfavorable and especially for high winding speeds because of the imbalances associated therewith.
  • a substantial drawback of some of the usual chuck constructions is the danger that on breakage of the inserted core sleeve the movable, tensioning elements of the chuck construction are centrifuged or thrown off from theshaft, something which is intolerable and especially in the case of high turning rates.
  • the chuck in which tension bands or strips are pressed radially outward at a standstill by means of an axially operated spring device develops its full tensioning force only through the centrifugal force active during the winding process.
  • the bands are held together radially only at both ends in each case by a weak spring ring.
  • these rings furthermore have the function of pressing the bands inwardly so that the winding can be drawn off from the shaft.
  • One object of the present invention is to provide a winding shaft chuck for core sleeves, bobbins or the like which will operate effectively under all-thread winding conditions, including a safe and positive insertion and withdrawal of interchangeable sleeves, either in the event of breakage or during normal loading and unloading of the bobbins.
  • Another object of the invention is to provide a chuck which assures easy insertion of the empty core and a simple removal of the wound core sleeve or bobbin while safeguarding against the flinging or throwing off of tensioning elements in case of sleeve breakage.
  • Still another object of the invention is to assure an exact centering of the bobbin or core sleeve in the direction of the winding shaft axis and also to provide a sufficiently great area of tension or gripping contact to compensate for the usual variations in core sleeve diameter. Also, in the case of occasionally occurring constrictions of the core sleeve, it must still be possible to draw off the bobbin or winding without it becoming stuck or wedged on the chuck.
  • a sleeve chuck for a thread winding device which is essentially a chuck with radially expanding elements to engage or grip selected interior portions of a core sleeve or bobbin tube under a continuing predetermined spring-tensioned pressure exerted by the gripping elements and supplied through a relatively simple resilient rotational movement between springconnected shaft means and cage means concentrically arranged within each other to provide a cammed and.
  • the sleeve chuck of the invention essentially comprises a shaft means rotatable within and encircled by a concentrically positioned tubular cage having a plurality of openings at selected positions on its circumference; a plurality of individual gripping elements carried by said shaft means for movement radially thereof in each of said cage openings in response to the rotational movement of the shaft relative to the cage; means to retain each of said gripping elements at least partially within its cage opening while also permitting its radial movement outwardly beyond the circumference of said cage for engagement with an interchangeable thread winding core sleeve; and spring means interconnecting said shaft means and said cage and arranged to resiliently urge the cage to rotate relative to the shaft in the direction causing the radial outwardly gripping movement of said gripping elements.
  • the chuck of the invention proceeds from the generally known free-wheeling or so-called coaster principle in which outer and inner concentric cylindrical members are freely rotatable with respect to each other, one'member acting as the drive member while the other is the driven member by means of an intermediate wedge or key linkage, it should be recognized that the present invention also provides a resilient but positive radial engagement between the chuck as the inner member and a core sleeve for the winding as the outer member regardless of whether the device is at a standstill or is being rotated for conventional winding operations/It is especially preferred to provide a device in which the chuck is the driven member while the core sleeve or bobbin tube is the drive member and in turn is driven by a conventional drive roller on its circumferential surface.
  • the gripping elements of the invention can be constructed in the form of rollers or spherical balls, the lat-.
  • rollers offer the advantage that with equal gripping or expanding force, local stresses on the core sleeve of the bobbin can be kept-smaller. It is advisable to provide cylindrical rollers which extend axially over not more than one-half of the core sleeve being gripped.
  • gripping elements which are in themselves provided with cammed surfaces for engagement with preferably a shaft means having a circular cross-section over its entire length or with shaft means which may also have irregular or cammed surfaces of gradually increasing radius as measured from the axis of rotation of the winding device. Other variations of such combinations are explained in greater detail hereinafter.
  • an embodiment is preferably adopted wherein thecage receiving the gripping elements is extended at one end, preferably toward the end closest to the machine frame, i.e. an extension beyond the zone of the core sleeve to be gripped, in such a way that it can be braked independently of the winding shaft through a circumferentially engaged braking means.
  • the requirement for the troublefree functioning of the device of the invention can be achieved also whereby the force" acting inside the chuck toward a gripping expansion is not completely lost when startingor when braking the winding shaft or the bobbin.
  • the winding shaft is essentially formed in such a way that in the relative turning between the cage means and the shaft means, the gripping elements are shifted or forced either outwardly (first turning direction) or frees these elements again (second or opposite turning direction), i.e. a reversal of the turning allows the release of the gripping elements.
  • first turning direction first turning direction
  • second or opposite turning direction second or opposite turning direction
  • shaft of the chuck has an equilateral polygonal crosssection, i.e. in the axial sections interacting with the gripping elements, for example with a cross-section in the form of an equilateral triangle, a square, a regular pentagon, etc.
  • the center of the incribed circle or of the circumscribed circle of the polygon lies on the shaft axis, i.e. the axis of rotation of the winding.
  • the corresponding edges of the polygons are prefera bly rounded, so that the circumscribing circle can be somewhat greater than the inside-diameter of the surrounding cage receiving the gripping elements.
  • the gripping elements are released when a line or plane through the winding axis and extending along the center line or axis of a gripping element stands perpendicular to the facing irregular or cammed surface of the engaging shaft, while a relative rotation to the right or-left brings about an outward radial shifting of the gripping elements.

  • the triangular plate 73 on shaft 74 is likewise tensioned in the direction of the arrow by means of a spring.
  • Plate 73 has on each of its apices a large rounded opening or re-entrant curved recess by which the elongated end of the gripping element 68 is carried along.
  • the gripping elements 68 are guided in this case by means of axles or pins 71 held in radial slots 70.
  • the chuck of the invention is more easily adapted to variations in the inside diameter of bobbin tubes, and again because of the resilient spring means cooperating in the gripping movement during a winding operation, there islittle danger of a bobbintube slipping down or out along the chuck. Also, tube breakage caused by rotational imbalances, gripping or clamping variations or the like are largely avoided. With separate chuck and spring means on the same winding shaft, these advantages are achieved whether winding a single long bobbin or two shorter bobbins.
  • a sleeve chuck for a thread winding device which comprises:
  • a shaft means including a shaft of circular crosssection over its entire length rotatable within and encircled by a concentrically positioned tubular cage having a plurality of openings at selected positions on its circumference;
  • gripping elements carried by said shaft for movement radially thereof in each of said cage openings in response to the rotational movement of the shaft relative to the cage, said gripping elements being constructed as cam members having at least one portion of gradually increasing radius and being mounted in said cage openings for engagement with said shaft;
  • spring means interconnecting said shaft means and said cage and arranged to resiliently urge the cage to rotate relative to the shaft in the direction causing the radial outwardly gripping movement of said gripping elements.
  • a sleeve chuck for a thread winding device which comprises:
  • a hollow shaft means with uniformly arranged openings over its circumference for receiving gripping elements
  • said gripping elements are constructed as cam members having at least one portion of gradually increasing radius and are in direct contact with a plate member, with guide means to direct said gripping elements in a radial direction.
  • each of said plate members is composed of a plurality of congruent sectors of gradually increasing radius relative to the shaft axis, and each of said gripping elements is constructed as a body of revolution.
  • a device as claimed in claim 3 wherein individual shafts bearing said plate members are each rotatably mounted in a two-part basket member fixed within the hollow bore of said shaft, said spring means operatively connecting at least one of said plates and its associated gripping elements with said basket member.
