Definitions

  • cal discs When these discs are displaced relative to each other they tend frictionally to engage the inner wall of the spool sleeve.
  • Other known clamping devices employ centrifugally responsive weights which when at rest engage the spool sleeve with a slight frictional pressure by the action of rubber springs. This pressure is increased by the centrifugal force during operation. It is also known to provide clamping devices in which radially disposed and relatively slanted elongated springs .in dual arrangement are displaced relative to each other so that the radius of the spring assembly is enlarged whereby the springs engage the inner wall of the spool sleeve.
  • the aforedescribed means and devices effect a centered support of the spool sleeve on the spool carrier and the detachable spool shaft, but they are not suitable to be gripped when full spools are to be exchanged.
  • the spool carrier must be capable of carrying the weight of the spool sleeve and the textile material thereon not only when inserted in the machine but also when removed from the machine.
  • a spool support which serves to support the sleeve of the spool, both in the machine and during the exchange of a spool.
  • This spool support comprises two metal slides which are slidable relative to each other against the action of a loaded spring. One of the slides releases the spool support from the spool shaft in response to finger pressure against the action of the spring and the other clamps the spool support to the Spool sleeve by finger pressure against the action of the spring.
  • a spool support of this kind has the disadvantage that the area of engagement between the respective slide and the inner wall of the spool sleeve is comparatively small.
  • the resulting pressure of the slide upon the sleeve wall is or may be high enough to damage the sleeve.
  • the actuation of two actuating means for the sleeves having different functions is confusing to the operator.
  • the two slide grip does not offer a sufficiently safe grip to the hand of the operator so that the spool tends to slip rather frequently out of the hand of the operator.
  • the assembly of the spool support mechanism and the spool shaft is comparatively difiicult and cannot be conveniently made by the operator.
  • one of the objects of the invention is to provide a novel and improved clamping device which permits a convenient and rapid exchange of a full spool by an empty one without touching the uppermost layer of the textile material on the full spool.
  • Another object of the invention is to provide a novel and improved clamping device which effectively prevents or at least impedes touching of the textile material on the spool by the operator when removing a full spool from the machine.
  • Still another object of the invention is to provide a clamping device which on one hand safely and strongly supports the spool within and outside the machine and on the other hand affords a convenient grip for the op erator so that he can manipulate the spool for purpose of exchange without touching the textile material thereon.
  • a further object of the invention is to provide a novel and improved clamping device the actuation of which involves the manipulation of the same component for both clamping and release of the spool thereby greatly facilitating actuation of the clamping device.
  • the clamping device comprises clamping members or tongs which are pivotal between two limit positions and grip the spool sleeve in either limit position and release the same in an intermediate position.
  • the clamping members are urged into one of the limit positions by spring pressure when the spool is inserted in the machine and may be moved, for purpose of exchanging the spool, first into the other limit position and then into the intermediate position by finger pressure against the action of the spring.
  • a correspondingly shaped carrier such as a star shaped carrier.
  • Fig. 1 is a plan view of a clamping device according to the invention, one of the clamping members being omitted.
  • Fig. 2 is an elevational sectional view of the clamping device.
  • Fig. 3 is a detail view of one of the clamping members.
  • Fig. 4 is a fragmentary plan view of a modification of the clamping members suitable particularly for soft spool sleeves, and
  • the assembly comprises a removably mounted shaft 1 which is shown disposed within a spool sleeve 14 coaxially therewith.
  • Shaft 1 is secured by means of an external thread and a nut to a spool carrier 2 having radiating arms, three arms being shown.
  • Each of the arms ends in -a roller or cylinder shaped bearing head 3 the axis of which is parallel to the axis of shaft 1.
  • Each of bearings 3 serves to receive a clamping member generally designated by 4. To simplify illustration, one of the clamping members is omitted in Fig. 1.
  • each clamping member is formed with a clamping head 6 from which extends a handle or arm preferably ending in a bent-olf grip.
  • each clamping head is formed with a bore 7 partly opened by a lateral slot or gap 8 so that the clamping members can be conveniently slipped upon bearings 3.
  • Each clamping head 6 has along its outer edge a shelf or shoulder 9 underlying the respective edge of sleeve 14 as can best be seen in Fig. 2. There are further provided at opposite sides of the clamping head protrusions 10 and 11 respectively.
  • the configuration of the clamping heads and the length of the arms of carrier 2 in relation to the inner diameter of sleeve 14 are so correlated that the clamping members can perform a limited pivotal movement when mounted within sleeve 14.
  • Fig. 1 shows the two limit positions 12 and 13 of the clamping members in full lines and dashed lines respectively.
  • the respective protrusion 10 or 11 engages the inner wall of sleeve 14 with a clamping grip whereas in an intermediate position of the clamping members the latter are released from the sleeve so that the sleeve and the clamping device therein may be conveniently separated.
  • Each clamping member has attached thereto a spring 15 disposed between arm 5 and the respective arm of carrier 2 whereby the clamping members are urged into the clamping position 13 when the assembly is inserted in the machine.
  • a spring 15 disposed between arm 5 and the respective arm of carrier 2 whereby the clamping members are urged into the clamping position 13 when the assembly is inserted in the machine.
  • the clamping device is shown as further comprising an optional second carrier 16.
  • This carrier may either be a full disc or a member having radiating arms such as a star shaped member. It peripherally engages the inner wall of sleeve 14 with a friction grip and is seated upon shaft 1 by any suitable means such as a socket or bush coupling 17 which may be made of yieldable material for instance, rubber.
  • Carrier 2, clamping members 4 and carrier 16 may be made of any suitable material, preferably a plastic.
  • the operator places the full spool in vertical position upon a spool board with his hand the fingers of which are gripping the clamping members 4. Thereupon he releases the clamping members sufficiently to permit the same to pivot into the intermediate position by the action of loaded springs 15.
  • the carrier together with the clamping members can now be withdrawn from the full sleeve for insertion into an empty sleeve.
  • the clamping device is inserted into the empty sleeve by retaining clamping members 4 in the intermediate position and subsequently forcing the clamping members into position 12 thereby clamping the clamping device to the empty sleeve.
  • the second carrier 16 if any, is fitted with the second hand upon shaft 1.
  • the completed assembly is now inserted in the machine. Upon release of members 4, the same are turned by springs 15 into clamping position 13.
  • clamping heads 6 as hereinbefore described, engage the inner wallof the spool sleeve only. If desirable,
  • the frictional grip between the clamping heads and the sleeve wall may be amplified by giving the clamping heads configuration such that they engage an outer wall portion of the sleeve also.
  • Fig. 5 shows an arrangement in which an abutment member 19 extends from each arm of carrier 2.
  • This abutment member is parallel to the respective contour of outer sleeve wall 14 so that it forms an abutment for either protrusion 10 and 11 when the same are in frictional engagement with the inner sleeve wall.
  • a deformation of a soft sleeve wall is entirely or nearly prevented.
  • a clamping device for mounting the sleeve of a spool as used in textile fiber working machines, said device comprising a carrier fittable within a sleeve to be mounted, several clamping members supported on said carrier and pivotal between two limit positions, said clamping members being disposed to clamp in either limit position the inner wall of a sleeve fitted upon the carrier and to release said wall in an intermediate pivotal position for removal of the sleeve from the clamping device.
  • a clamping device for mounting the sleeve of a spool as used in textile fiber working machines, said device comprising a carrier having radiating arms fittable within a sleeve to be mounted, several clamping members each supported on the end of one of said arms pivotal between two limit positions, said clamping members being disposed to clamp in either limit position the inner wall of a sleeve fitted upon the carrier and to release said wall in an intermediate pivotal position for removal of the sleeve from the clamping device.

  • each of said radiating arms of the carrier ends in a generally cylindrical bearing element having its axis parallel to the axis of a sleeve to be mounted, and wherein said clamping heads are pivotally fitted upon said bearing elements.
  • each of said clamping heads is formed with a bore for receiving the respective bearing element and a gap opening into the bore along the axial length thereof to fit each clamping member upon the respective arm of the carrier.
  • a clamping device wherein a spring means coacts with each of said clamping members for biasing said members into one of said limit positions.
  • each of said clamping members comprises an actuating arm extending from the clamping head in the general radial plane of the carrier arms, and wherein a spring means is disposed between each of said arms and the respective carrier arm to bias the said clamping member into the respective limit position.
