Definitions

  • a textile machine comprising a plurality of spin dles is provided with a track above the spindles, into which track there is insertable and removable a chain carrying means to hold yarn packages or yarn package supports whereby the spindles may be provided with fresh yarn packages and the yarn supports of the exhausted packages may be removed. Moreover removal of the exhausted yarn supports from the spindles and supplying of the fresh yarn packages can be accomplished automatically by providing the chain with expanding mandrels to grip the yarn packages or yarn package supports when not positioned to service the spindles and to be freely retractable from or insertable into the yarn package or yarn package supports when positioned to service the spindles.
  • This invention relates to apparatus in textile machines comprising a plurality of spindles.
  • this invention relates to an apparatus on a double twist spindle frame for supplying the spindles with bobbins and for carrying away the empty yarn carriers by means of a chain provided with bobbing receivers in the same spaced arrangement as the spindles, which is guided on a chain guiding rail extending above the spindles.
  • the bobbins are brought from one end of the machine into the working area of the individual spindles by means of a circulating endless chain, so that the bobbins'merely need to be placed on the spindles by the operator.
  • the same endless chain can be used to bring the winding tubes to the spindles and to bring the empty tubes back to the one end of the machine.
  • these arrangements permit the serving aisles between the individual machines to be kept very narrow, since it is no longer necessary to carry bobbins and tubes along the machine in vehicles. The reduction of the aisle width results in an appreciable saving ofworking space.
  • the operator is relieved of this work.
  • placing of the bobbins on the spindles and the removal of the empty tubes from the spindles can be performed automatically, so that the bobbins and tubes no longer have to be grasped and moved by the person operating the machine.
  • a chain guiding rail into which the chain can be inserted from one end of the machine and can be taken out in the same direction or the opposite direction, extends in a straight line above each row of spindles, and the bobbin receivers on the chain are in the form of mandrels over which the top ends of the bobbins and tubes can be placed.
  • the receiving mandrels on the chain can be mounted with bobbins away from the machine, at a central station where all the chains are prepared, if one so desires, and the chain'thus prepared can be brought to the one end of the machine and inserted into the chain guiding rail, so that all of the bobbins will be brought automatically into the ready position above the spindles onto which they are to be placed.
  • the empty tubes can be taken from the spindles and placed on the mandrels.
  • the chain carrying the empty tubes can then be carried away from the machine and the empty tubes replaced with full bobbins at the preparation station.
  • the chain guiding rail in conjunction with the insertable chain makes possible simplification of the mounting of the full bobbins on the spindles and automation of that mounting by means of further measures.
  • the chain guiding rail to be disposed pivotingly between two end positions about an axis extending parallel to the rail, and for downwards. Owing to the pivoting of the chain guiding rail from the aforementioned first position to the aforementioned second position, the bobbins need only a downward movement to place them on the spindles.
  • the placing of the bobbins on the spindles can be made performable in a completely automatic manner due to the fact that, according to the invention, the expanding mandrels on the chain consists of a mandrel and retractable dog which can be pivoted back into the mandrel against the force of a spring and which is provided with an operating arm extending outward. By the pivoting of the dog back into the mandrel the mandrel releases the full bobbin it is carrying so that the bobbin automatically drops down onto the spindle.
  • a stop rail extending beneath the chain guiding rail and parallel thereto, against which the expanding mandrel operating arm comes to rest when the expanding mandrel is directed downward, thus retracting the dog into the mandrel; this releases the full bobbin which has been held on the mandrel by the grip of the dog, and the bobbin can slide downward onto the spindle.
  • stop rail prefferably displaceable horizontally from a position of rest to the position associated with the operating arm of the retractable dog when the expanding mandrel is directed downward.
  • the feature last mentioned can also be used when provision is made according to the invention for the chain guiding rail and the stop rail to be commonly displaceable vertically.
  • the pivoting movement of the chain guiding rail may be performed, not on a circular arc, but on a trajectory differing therefrom, which can also include a lowering movement of the chain guiding rail, in order thus to make it possible for the full bobbin not to be released from the expanding mandrel until it is in its working position on the spindle.
  • An inverse course is required for the lifting of the empty tubes from the spindle and their removal from the reach of the spindles so that they can be taken out of the machine by means of the chain.
  • the chain guiding rail can be borne by four-point linkages which can pivot in common perpendicularly to the longitudinal axis of the machine, and by whose pivoting the chain guiding rail can be pivoted from the first, i.e. chain insertion, end position to the position in which the expanding mandrels on the chain are pointed downward over the spindles and in axial alignment with the spindles.
  • the four-point linkage member can be articulated to a slide that is mounted so as to be vertically displaceable on the machine frame, can bear the chain guiding rail on a portion extending beyond the second joint, and can be connected by two additional members to a rocking shaft which is stationarily mounted parallel to the chain guiding rail and can be rocked back and forth.
  • the empty tubes are to be removed from the spindles, the expanding mandrels are lowered down onto the spindles by means of the chain guiding rail by the pivoting of the latter; the mandrel grip the empty tubes and are then pulled away from the spindles by the pivoting of the chain guiding rail in the opposite direction.
  • the empty tubes can then be removed from the machine by taking the chain out of the chain guiding rail and then they can be carried
  • the operation of the expanding mandrels can be made possible by mounting directly on the chain guiding rail a rotatable shaft which contacts a contact surface on the operating arm of the dog of the expandling mandrel in each case, so that its rotation produces a retraction of the dog into the expanding mandrel against the action of a spring, and thus releases the tube or the bobbin that is being held by the dog on the mandrel.
  • the chain guiding rail combined with the chain that can be inserted from one end of the machine and removed therefrom, creates the possibility of providing the bobbin receivers with bobbins at a location remote from the machine, especially at a special chain preparing station.
  • the insertion of the chain can be performed automatically according to the invention by providing at least at one insertion end of the chain guiding rail a sprocket which meshes with the chain and can be driven in either direction, and which, when rotated in one direction pushes the chain into the chain guiding rail, and when rotated in the other direction pulls it out of the chain guiding rail.
  • At least one additional chain guiding rail opening tangentially to the sprocket can be placed in front of the chain guiding rail and can deliver the chain equipped with bobbins into the chain guiding rail on the machine and can receive the chain carrying the empty tubes.
  • This additional chain guiding rail can be disposed in a stationary manner and can extend all the way to the chain preparing station and the chain can be transported in the additional chain guiding rail by means of driven sprockets and can be brought to the machine itself from the chain preparing station by means of the additional chain guiding rail.
  • a chain switch can be placed ahead of the sprocket and can serve to connect the chain guiding rail of the machine alternately with one or two additional guiding rails aligned with the sprocket in different directions. In this manner a plurality of chain guiding rails can in the ready position to deliver chains of fresh bobbins and rficeive the chain emerging from the machine and bearing empty tubes to be carried away.
  • the chain switch system permits either of the chain guiding rails to be brought into transfer alignment with the chain guiding rail on the machine.
  • a chain guiding rail that can be placed in front of the chain guiding rail on the machine can becurved in a spirallike manner in a vertical plane and arranged on a transport car, so that a chain equipped with full bobbins can be brought to the machine on this transport car.
