Definitions

  • the thread reserve forming devices of the invention comprise a thread guide roller rotatable about an axis which preferably is oblique to the axis of Winding tube, which roller has at least one cylindrical or frusto-conical surface with spiral grooves which receive a thread or other yarn or filament, hereinafter designated generically as thread, as it is initially wound on the winding tube.
  • threads are wound on a rotatably driven winding tube such as a winding spool, winding pirn, winding bobbin, etc., while causing the thread to reciprocate back and forth as it is wound.
  • the reciprocation is called the traverse guide stroke.
  • the winding devices of this invention are located just outside the traverse guide stroke and guide the thread as it is wound initially on the winding tube. The initial winding, thus, is outside the traverse guide stroke for the winding body proper and forms, usually at the base of the winding tube, a separate winding or windings known as a waste thread winding and/ or a thread reserve winding.
  • Waste thread windings are windings of thread to be cut away from the threads of the winding body proper and/or thread reserve windings and to be discarded.
  • This invention therefore, provides an advance in the art by providing a device for the formation of a thread reserve on winding mechanisms, which device operates without a special drive means, assures a gentle treatment of the leading or initial thread ends which are handled thereby and the consistent feed during such handling of approximately equal lengths and, finally, makes possible by certain embodiments the separate deposition of a preceding thread waste winding ahead of the thread reserve winding.
  • the invention provides for the formation of the thread reserve winding a cylindrical and/or fru'sto-conical thread guide roller borne to turn freely on an axis set obliquely to the axis of rotation of winding spindle and the winding tube thereon.
  • the roller is provided on its circumference with a screw thread by which the running thread is guided to the free end of the roller.
  • This thread guide roller can be provided with two or more screw thread sections axially spaced on the roller circumference, which sections may have different screw thread pitches.
  • the bearing pin on which the thread guide roller is freely rotatably borne may be fastened by means of a clamping device to a stationary machine part and may be equipped, if desired, with a thread guide bow.
  • the thread guide rollers of the invention are of surprising reliability in operation. They require no separate drive and no maintenance and can be mounted with the simple means on the machine frame and adjusted to the particular thread course.
  • the thread at the start of its winding is merely laid over the roller near its base. It slips into the rearmost threads and then begins, by friction of the deflected, running thread, to turn the roller. With the aid of the screw thread or spiral groove, the rotating roller shifts the running thread toward its free end, where the thread is thrown off and is caught by the reciprocating thread guide of the transverse guide mechanism and is then wound to form the winding body proper.
  • the first thread windings because the thread running at a constant speed requires a certain amount of time for the acceleration of the roller to a peripheral speed near the linear speed of the thread, will lie closer together in the thread reserve winding or the waste winding than is later the case when the roller has gone into full speed rotation.
  • two, separate, screw axially spaced thread sections which are connected with one another by a thread transfer means, are arranged on the thread guide roller in such a way that the thread in the initially wound thread end is distributed with the desired winding number and pitch and with clear marking with respect to the waste end.
  • roller can be frusto-conical or in cylindrical or frustO-conical step form.
  • Another object is to provide, for use in a thread winding machine having a winding station comprising a spindle rotatably supporting a winding tube, means to rotate said winding tube, and a traverse guide device for reciprocating the running thread as it is wound on said tube, a thread guide roller having a screw thread on the roller surface, stub axle means extending into an axial end of said roller and rotatably supporting said roller, the other axial end of said roller being an end free of obstructions to thread passing thereover, and means for supporting said stub axle means and said roller at a winding station of a thread winding machine contiguous to an end of the winding tube of said station with the axis of said roller extending obliquely toward said winding tube.
  • a more specific object is to provide in the aforesaid combination and thread guide roller subcombin-ation a roller composed of two axially spaced screw thread sections of the same hand.
  • Another more specific object is to provide two screw sections as aforesaid with respective threads of different pitch.
  • a further more specific object is to provide in the aforesaid combination and thread guide roller subcombination a roller support comprising a rod having one end extending axially into said end of said roller and also shaped in the form of a thread guide bow.
  • Still another more specific object is to provide a roller support member comprising a rod extending axially into an end of said roller and clamping means on said rod for mounting said rod and roller to a stationary member of said winding station.
  • FIGURE 1 is a perspective view of a winding station of a thread winding machine and shows an embodiment of a thread guide roller of the invention and its relationship to the winding mechanism of the winding station;
  • FIG. 2 is a perspective view of another thread guide roller embodiment with the roller shown in diametric cross-section;
  • FIG. 3 is a perspective view of another thread guide roller embodiment
  • FIG. 4 is a side elevation of the embodiment of FIG. 3 with respective threads of different pitch in the two thread sections;
  • FIG. 5 is a top plan view of a winding station similar to FIG. 1 with the thread guide roller, thread guide bow and associated mounting structure illustrated in FIG. 2.
  • the winding machine station is of usual construction and comprises a drive roller 11, a winding tube spindle 13 rotatably journalled on the swinging arm 12, on which spindle there is placed the winding tube 14, and a reciprocating thread guide 15.
  • Roller 11 is mounted on a gang drive shaft which commonly drives rollers 11 and each winding station.
  • the thread 16, delivered by or drawn oif from the stretching or twisting device, for example, is conducted over or through a thread guide means 17 constructed as a roller, eye or the like. The latter is arranged approximately centrally opposite the winding tube 14.
  • the advance end of the thread 16 is secured on the base end of the winding tube 14and the initial part of the winding is first deflected laterally over the lower end of the thread guide roller 18 in the screw thread 19 near the base of the guide roller 18.
  • the running thread by friction sets the easily turnable roller in increasing rotary movement and is conveyed in the spiral screw thread groove to the free end of the roller 18.
  • the thread is wound on the tube 14, depending on the oblique position of the roller 18 with respect to the tube 14 in a more or less broad or narrow thread reserve winding.
  • the thread then jumps over the slightly rounded or conical face surface of the roller 18 into the traverse stroke range of the self-threading, reciprocating thread guide 15, is carried along by this and in a known manner, and forms the winding body proper, distributed beside the thread reserve winding on the winding tube.
  • the thread guide roller is rotatably journalled on the stub axle end of support rod 20, the other end of which is releasably coupled by clamp sleeve 21 on the fixed rod 22 of the winding machine in the proper, spaced relation to winding tube 14.
  • the support rod 20 provides an axis of rotation for roller 18 extending obliquely toward the winding tube 14.
  • the free end of the roller 18 is contiguous to and substantially faces the winding tube 14 and provides an end unobstructed to passage of thread thereover. This provides a combination whereby the initial portion of running thread being wound may be deflected over the screw threaded surface of said roller to frictionally rotate said roller and thereby convey said thread in said screw thread to the free end of said rotating roller, during which said thread reserve winding is formed.
  • the cylindrical or frusto-conical form thread guide roller 28 consists essentially of a cylindrical, rotatably journalled core 23, on the upper face of which there is made a concentric recess 24 for the reception of a snap ring 25, as well as of the cup-shaped shell 26, the outer circumference of which is provided with a screw thread 27.
  • the core 23 and/ or the shell 26 can be made of light metal or plastic, especially polyamide, or of sinter material and are joined securely together, for example, by cementing.
  • the support rod for the thread guide roller 28 is a thread guide bow 29, one end of which is the stub axle pin 30 with conical point 31 and a locking groove 32 for the snapping in of the snap ring 25 and the other, U-bent end of which is fastened by means of clamp 33 and screw 34 to the stationary rod 19.
  • the right-hand U-loop 42 provides resilient support for the thread guide bow 29 to give the thread guide bow resilient flexibility if it is contacted by the running thread.
  • the left-hand U-loop 43 has an upstanding tip or rod 44. Normally the thread T does not contact the thread guide bow 29, its tip or rod 44 or guide roller 28 as the thread traverses winding tube 14 over traverse angle a in forming winding W.
  • FIG. 3 shows a two-stage, thread-guide roller 35 rotatably mounted on the rod 20 with two, different diameter, screw thread sections 36 and 37 lying axially one behind the other with a frusto-conical wall 38 therebetween.
  • the respective screw threads of sections 36 and 37 may be of the same or of different thread pitch and are of the same hand.
  • the base of the roller may have a flange 39 with a frusto-conical wall 40 for guiding the thread into the rear portion of screw thread section 36.
  • the tip 41 of roller 35 is conical.
  • FIG. 4 is like in most respects to the embodiment of FIG. 3. It illustrates, however, screw thread sections 36 and 37 of the same hand wherein the threads of rear section 36 have a greater pitch than the pitch of the threads of front section 37 at the free end of roller 35.
  • the thread sections of different thread pitch and the axial space therebetween which is provided by frusto-conical wall 38, provides sharp delineation between the thread waste winding resulting from rear thread section 36 and the thread reserve resulting from front thread section 37.
  • the advantages of the thread guide rollers herein lie above all in completely sure operation and in the elimination of special drive means whereby they are surprisingly simple and inexpensive devices and can be mounted readily on the winding mechanisms of stretching or twisting machines on hand.
  • a device for forming a thread reserve winding prior to forming the thread winding body proper comprising a thread guide roller having a screw thread on the roller surface, roller supporting means rotatably supporting said roller contiguous to an end of said winding tube, said roller supporting means embodying a rod extending axially into one end of said roller, a thread guide bow having an arm extending across said roller with said roller between said arm and said winding tube, an upstanding rod on an end of said arm, said rod forming a thread path deflection member when the thread path is deflected into said screw thread of said thread guide roller, and the opposite, free end of said guide roller providing an end unobstructed to passage of thread thereover and facing toward said winding tube, whereby the initial portion of running thread being wound may
  • said thread guide bow comprises a rod bent into U-loops at opposite ends of said arm with said upstanding rod projecting upwardly from an end of one U-loop.
  • said screw thread being composed of two axially spaced screw thread sections of the same hand and of different diameters with a frusto-conical wall therebetween, the section of smaller diameter being adjacent said free end.
  • a thread guide roller useful for forming a thread reserve winding contiguous to the winding body proper on a winding tube of a winding machine comprising a roller having a screw thread on the roller surface, stub axle means extending into an axial end of said roller and rotatably supporting said roller, the other axial end of said roller being an end free of obstructions to thread passing thereover, means adapted for mounting said stub axle means and said roller thereon on a thread winding machine contiguous to an end of the winding tube, and a thread guide bow mounted on said last-mentioned means and having an arm extending across said roller with said roller between said arm and said winding tube, an upstanding rod on an end of said arm, said rod forming a thread path deflection member when the thread path is deflected into said screw thread of said thread guide roller.
