Definitions

  • An automatic yarn twisting or spinning and rewinding system has at least one spinning frame with opposite banks of spinning stations.
  • a pair of tenders one for each of the banks, is provided for patrolling the stations and servicing any of the stationsrequiring attention.
  • the tender Upon stopping at a station requiring servicing, the tender doffs the bobbin (supply unit) at the station and donns an empty bobbin and starts the strand winding onto the empty bobbin.
  • the tender doffs the bobbin (supply unit) at the station and donns an empty bobbin and starts the strand winding onto the empty bobbin.
  • the filled bobbins are conveyed to a readier of a winding machine at an end of the spinning frame or frames and, responsive to demand of the winding machine, the filled bobbins are deposited in the readier where they are suitably processed and then delivered to winding stations of the winding machine.
  • the system is regulated so that the winding machine continuously uses the filled bobbins at substantially the same rate at which they are doffed from the spinning frame.
  • the bobbins may be ejected from the winding machine and are transferred back to a tender which thereupon donns the empty bobbins, as required, at the spinning stations.
  • This invention relates to a strand handling system and, more particularly, to a system for spinning or twisting strands into supply units which are consecutively transferred to a winding machine and rewound into packages at substantially the same rate at which they are formed.
  • twisting machine refers to a twister or a spinning frame, or any other similar mechanism.
  • bobbin means a unit of strand material formed so that it may be readily moved from place to place, and includes any core or other member on which the strand material is or may be formed.
  • filled bobbin means a bobbin having strand material thereon, whether full or partially full.
  • empty bobbin means a bobbin devoid or substantially devoid of strand materiah
  • yarn is employed in a general sense to apply to all kinds of strand material either textile or otherwise.
  • a new system includes a tender which patrols one side of one or more spinning frames and swings about the ends of the frame or frames to patrol the other side thereof.
  • winding machines are well known in the art and include machines having stationary winding stations each of which may be equipped with a knotter and other servicing equipment or, alternatively, may be serviced by a traveling tender. Still another type of winding machine has a plurality of winding stations which travel past a fixed servicing station at which empty bobbins are ejected and filled supply bobbins are donned onto the stations and winding is started onto an associated package.
  • the present invention in brief, is directed to a twisting machine such as a twister or a spinning frame with provision for successively servicing stations thereof and consecutively transferring doffed, filled supply bobbins (units) from the stations to any suitable type of winding machine having provision for donning the supply bobbins on stations of the winding machine and starting the strand material from each supply bobbin winding onto a package being formed at the station.
  • the system provides for the winding machine utilizing the supply bobbins at substantially the rate at which they are doffed from the twisting machine.
  • the system may also return empty bobbin cores ejected from the winding machine to the twisting machine for donning thereon, thus effectively eliminating the need for any substantial bobbin storage between the twisting machine and the winding machine.
  • a more specific object is provision of a system for processing strand material to form packages, the system including first mechanism for concurrently forming the strand material into a plurality of supply units and generally completing formation of each of the supply units at successive intervals, second mechanism for successively receiving the supply units and concurrently forming a plurality of the packages from the supply units at substantially the same rate at which the supply units are completed by the first mechanism, and third mechanism for successively removing each of the supply units from the first mechanism and substantially continually transferring the supply units to the second mechanism.
  • a related object is provision for transferring ejected supply units from the second mechanism back to the first mechanism to again be formed into useable supply units.
  • FIG. 1 is a foreshortened, schematic, plan view of a preferred embodiment of the invention, with parts broken away and removed for clearer illustration;
  • FIG. 2 is a foreshortened, schematic elevational view of the system shown in FIG. 1, with parts broken away and removed for clearer illustration.
  • the system is illustrated as including a plurality of typical spinning frames 10 having their opposite banks 12 of spinning stations 14 aligned.
  • a pair of tenders 16, one for patrolling the stations 14 of each of the opposite banks 12, is provided as disclosed in the aforementioned patent.
  • the tenders l6 automatically stop at any of the stations 14 of the associated bank 12 requiring servicing, and upon stopping at a station 14 the tender 16 normally doffs a filled supply unit or bobbin l8 and donns an empty core 20 of a bobbin and starts a strand of roving spun into yarm 22 winding onto the donned bobbin.
  • Each of the doffed (filled) bobbins 18 is deposited onto a filled bobbin portion 24 of a conveyor belt system 26.
  • the tender 16 receives a core of an empty bobbin 20 from an empty bobbin portion 28 of the conveyor belt system 26 and carries the empty bobbin 20 to a position for donning onto another spinning station 14 requiring servicing, for example as in more fully disclosed in a co-pending commonly assigned United States patent application, Ser. No. 863,858, filed Oct. 6, 1969, now US. Pat. No. 3,627,107 and incorporated by reference.
  • a filled bobbin 18 is elevated to an upper discharge end of the elevator and drops into a declining chute 36 which deposits the bobbin in suitable handling mechanism 38 (readier and/or knotter) of the winding machine 34 for subsequent passage through a chute 40 for donning at one of a plurality of winding stations 42 (FIG. 2) of the winding machine.
  • suitable handling mechanism 38 readier and/or knotter
  • Any suitable control system may be provided for operating the filled bobbin elevating conveyor 32.
  • this conveyor may be operated by the same control system of the winding machine 34 which operates the handling mechanism 38.
  • the winding machine 34 is of the traveling winding station type in which the stations 42 move in a continuous path and stop at the bobbin handling mechanism 38 whereeach station may eject a spent supply bobbin 20 and receive a filled supply bobbin 18, and then proceed to travel in the continuous path while winding their packages 44.
  • the ejected bobbins 20 pass through a declining chute 46 (FIG. 1) and are deposited on an elevating conveyor belt 48 which may be constantly driven.
  • a bobbin sorting system may be provided for example, this sorting system may be the same as that disclosed in a copending Leesona Corporation patent application, United States Ser. No. 857,848, filed Sept. 15, 1969, now US. Pat. No. 3,606,0l2.
  • Such sorting system includes any suitable type of bobbin sorter 50 having a chute 52 (FIG. 1) for receiving the ejected bobbins 20 from the conveyor 48. After being sorted, empty ones of the bobbins are delivered through a cute 54 (FIG. 1) to the empty bobbin portion 28 of the conveyor belt system 26 of the spinning frames 10.
  • Filled ones of the ejected bobbins 20 are delivered from the sorter through a chute 56 to the filled bobbin portion 24 of the conveyor belt system 26 for return to the bobbin handling mechanism 38.
  • the mechanism 38 may be equipped to inspect the bobbins and to discharge through a chute 58 any bobbins which are not suitable for transfer to the winding stations 42. From the chute 58 the bobbins failing to pass inspection are deposited in a bin 60 for manual inspection and correction of the difficulty and are returned to the appropriate conveyor portion 24 or 28 of the spin-wind system.
  • Either the number of stations of the winding machine 34 or the spinning frames may be regulated so that these machines operate at substantially the same bobbin handling rate.
