Definitions
- ABSTRACT A smaller than the inside diameter of its adjacent hollow core bobbin and a resilient annular portion carried between the ring core having an outside diameter at least as great as the outside diameter of the empty bobbin.
- the annular portion is deformable for sliding a filled bobbin'axially over the resilient portion; and, when the bobbin is removed, such portion resumes its original shape.
- the resilient annular portion may be flexible bristles for catching a bight of thread pulled across it or may be a perforated hollow ring connected to a suction source.
- the present invention relates to a thread bight catching device adjacent toa bobbin to hold a thread portion stationary relative to the bobbin and thereby facilitate positive control of the initial bobbin winding operation.
- continuous productivity depends on the ability to wind a continuous thread sequentially onto individual bobbins without interruption.
- a bight of thread must be restrained relative to an empty bobbin as it is rotated to begin winding of thread onto it and/or to prevent stretch thread or yarn being placed in tension.
- Two examples of applications of such thread-catching devices are used for winding stretch yarns onto bobbins or for winding thread continuously produced by open end spinning machines.
- the ring has no portion extending into the path of the thread, as it extends between the filled bobbin and the outer surface of the adjacent unfilled bobbin. The result is that the interbobbin spanning thread bight is not caught and arrested by the toothed ring automatically and reliably.
- Another means for grasping thread so that it will be positively wound onto an empty bobbin is to provide special bobbins having a thread-holding covering on the thread-winding surface, as disclosed in German Offenlegungsschrift Pat. No. 2,] 10,082.
- Such special bobbins are expensive to manufacture, and have the disadvantage of collecting fibers or thread clippings, which collection shortly coats or clogs the covering, so it loses its thread-grasping capability. Frequent cleaning of such coverings is necessary, which is time-consuming, and the covering is easily damaged by brushing or manual scraping of the accumulated debris.
- Another important object is to provide such a device which does not interfere with the axial doffing of bobbins.
- the thread-catching device is a brush having a cylindrical rigid core smaller than-the bobbin hollow core and resilient bristles extending from the core outward a distance such that the bristle tips define a ring having a diameter'at least as great as the outside diameter of the bobbin.
- the bristles may extend radially outward to simplify manufacture of the thread-engaging device.
- a more positive grip on the thread bight extending from the adjacent filled bobbin is effected if the bristles are inclined from radial lines cutting the bristle roots, so that the bristle tips project forwardly in the direction of rotation of the bobbin carrier.
- a hollow resilient perforate ring could be provided, the interior of such ring being connected to a suction source creating an airstream for drawing an adjacent thread bight into engagement with the resilient ring.
- the thread-catching member is mounted on the bobbin carrier by quickly-releasible fastening means to facilitate removal and substitution for cleaning.
- FIG. 1 is a front elevation of a bobbin carrier, on which is mounted a thread-catching member in accordance with the present invention, parts being broken away.
- FIG. 2 is an end elevation of one type of threadcatching member
- FIG. 3 is a similar view of a modified thread-catching member.
- FIG. 4 is an axial section through a filled bobbin partially removed from its carrier.
- FIG. 5 is an axial section through a bobbin carrier, including a modified form of thread-catching device, with parts broken away.
- FIG. 6 is a front elevation of a different type of bobbin carrier showing a thread-catching member in section.
- a bobbin carrier I receives a hollow core bobbin 2, which bobbin is rotated by frictional engagement with a drive roller 3.
- the core 4 of a thread-engaging brush having bristles 41 is connected to one end of bobbin carrier 1 by a screw 5.
- core 4 could be connected to carrier 1 by a snapengageable plug-and-socket connection for more rapid removal of the thread-engaging member 4,41.
- Bristles 41 extend outward from core 4 a sufficient distance so that the bristle tips form a ring having an outside diameter at least as great as the outside diameter of the bobbin, and such bristles may project beyond such bobbin diameter.
- Bristles 41 may project radially from the core 4, as shown in FIG. 2.
- inclined bristles 42 may be provided on core 4 as shown in FIG. 3, such bristles being inclined relative to radii of the core so that the bristle tips project forwardly in the direction of brush rotation. It has been shown experimentally that the member 4,42 more effectively catches a bight of thread passed over it than does the radial bristle member 4,41. It is preferred that bristles 41 are natural bristles to minimize abrasion of the thread and to avoid creation of electrostatic fields. Instead of natural bristles, bristle-like projections of resilient plastic, rubber or other resilient material could be mounted in the brush core.
- the core While'the size of the brush core relative to the radial projection of the bristles is not critical, the core must be inscribable in a circle having a diameter sufficiently shorter than the inside diameter of bobbin 2 so that the bristles are of sufficient length to bend resiliently in a direction axially of the core. Therefore, the bobbin can be slid from the carrier and over the bristles without across and bending brush bristles 41,
- the bobbin can be slid axially from the carrier, the interior of the hollow bobbin dragging or 42, to reduce automatically the effective brush diameter, and permit easy bobbin removal.
- the resilience of the bristles will cause them to resume their normal positions in planes transversely of the brush axis when the bobbin and its dragging force on the bobbin bristles are removed.
- an empty bobbin is placed on the carrier by sliding it axially across the bristles and thereby bending such bristles in the direction opposite that shown in FIG. 4.
- the resilient portion of the thread-catching member may be a resilient hollow annular ring 7, shown in FIG. as having a U-shaped cross section the closed bottom of which projects outwardly from core 8.
- the ring has a plurality of apertures 71 in its closed bottom.
- the core includes a passage 81 of T-shaped cross section, connecting the hollow of ring 7 with a bore 12 in the carrier 11. Bore 12 is connected to a suction source to draw air inward through apertures 71. The inward airstream created thereby will pull and hold an adjacent thread bight into engagement with ring 7.
- core 8 has a projecting portion forming a plug receivable in a complemental socket in the end of carrier 11.
- a full bobbin can be doffed and an empty one placed on the bobbin carrier 11 without removing member 7,8 because ring 7 is made of resilient material readily defonnable by the axial force exerted by a bobbin core wall, so that the diameter of the thread-catching member is reduced while such force is applied. After the axial force is relieved, ring 7 resiliently resumes its normal position shown in FIG. 5, so that the diameter of the threadcatching member again equals or exceeds the bobbin diameter.
- frames 9 have carrier members 91,92 forming end plugs for opposite ends of a bobbin 2.
- bobbins doffed and placed in the frame without being slid over the thread-catching member.
- the bristles 43 on a brush core 40, or an annular ring such as shown in FIG. 5 may have a shorter thread-catching member. It is, of course, essential, that the outside diameter be at least as great as that of the bobbin 2, as previously described,- so that a thread portion will be automatically received by the threadcatching member during the thread-transferring operation to effect winding of thread onto the bobbin immediately upon engagement of a thread portion with the empty bobbin surface.
- Apparatus for continuous winding of thread onto rotatable bobbins having transfer means for transferring a thread portion between a filled bobbin and an empty bobbin, said bobbins being arranged in end-toend spaced relationship, comprising a cantilever bobbin carrier having a free end, a bobbin having a carrierreceiving hollow therethrough and mountable on and demountable from said carrier by movement over said free end, and a thread-catching member mounted on said bobbin carrier free end adjacent to and axially aligned with a bobbin end, rotatable conjointly with said bobbin, and including a core having an extent in a diametral plane of said bobbin less than the diametral extent of said bobbin hollow and annular resilient thread-engaging means carried by said core, said resilient thread-engaging means having an outside diameter at least as great as the outside diameter of the adjacent bobbin end which diameter is resiliently changeable in response to movement of said bobbin over said threadcatching member.
- annular thread-engaging means is a ring of bristles having roots mounted in the core.
- the re silient thread-engaging means is a hollow annular ring having a plurality of apertures through its periphery, and suction means communicable with the ring hollow.
