Definitions

  • My present invention relates to a device for simultaneously monitoring the tension in two or more threads delivered, as in a twisting or spinning machine, to a bobbin-building mechanism or similar station wherein several threads are combined into a yarn.
  • the component threads may be delivered at identical rates to the twisting station by a common feed mechanism which may have associated therewith a conventional thread guard designed to stop the feed and, advantageously, to arrest the drive for the bobbin spindle or other take-up device for the yarn in the case of a rupture. If, however, the threads are to be continuously or temporarily supplied at different rates, separate feeders are required and individual monitoring of the several threads becomes necessary along with, preferably, a supervision of the tension in the resulting yarn. Thus, conventional thread guards can no longer be used in installations of this type.
  • the general object of my invention is to provide a monitoring device for bobbin-building mechanisms and the like which performs the individual supervision of the component threads in a simple manner and with a minimum duplication of parts.
  • An ancillary object is to provide means in such monitoring device for sensing an excessive slack, indicative of possible rupture, not only in the constituent threads but also in the resulting yarn.
  • I provide, in a plant of the aforedescribed character, a control mem ber common to the several thread-feeding units for concurrently deactivating same upon displacement of this member from a normal to an off-normal position, the control member being engageable for such displacement by several thread guards individually assigned to the respective threads so as to be maintained thereby in an inactive position against a biasing force, tending to move the control member into its off-normal position, as long as the associated threads are under normal tension.
  • the biasing force may be supplied by gravity and/or springs acting upon the several thread guards which advantageously are in the form of bell-crank levers urged
  • a United States Patent 3,388,544 Patented June 18, 1968 "ice by their own weight into engagement with respective abutments on a shiftable bar representing the aforementioned control member; the latter may be suspended, at or near its ends, from a pair of substantially vertical links defining therewith a parallelogrammatic linkage, the links themselves being provided with one-sided extensions loading the parallelogrammatic linkage for movement into its normal position in which the feeders are operative and the drive for the yarn take-up is energized.
  • Each feeding unit may in this case comprise a pair of coacting rollers, including a driven roller and a counterroller, arranged to be separated from each other by one of the aforesaid link extensions.
  • the thread guards could be disposed for engagement with their respective threads either ahead of or behind the associated feeding unit. If at least one of these thread guards is positioned downstream from the respective feeding unit, i.e. between that unit and the twisting station, it will register a slackening not only of the corresponding thread but also of the twisted yarn so as to obviate the need for a separate thread guard to monitor the yarn tension.
  • two separate reels 2, 2 deliver a pair of threads 1, 1 to respective feeding units 4, 5 and 4, 5' which individually advance these threads, possibly at different rates, to a twisting station in which the threads are combined into a yarn 8 to be wound into a bobbin 11.
  • Thread 1' after passing around a deflecting bar 7, joins the thread 1 in an eyelet 6 from which the yarn 8 advances to a traveler ring 10 which circles the axis of bobbin 11 on an annular track 9 reciprocating in the direction of the bobbin axis (arrow A) as is well known per se.
  • the bobbin 11 has a core 21 mounted on a spindle 22 which is driven, via a transmission 23, from a motor 24 whose power supply has been diagrammatically indicated as a generator 25 in series with a pair of contacts 16. It will be understood that, in accordance with general practice, a multiplicity of bobbins 11 are built simultaneously on a bank of spindles 22 which are usually so closely spaced that, in the event of a rupture, a loose thread will become entangled with the yarn of a neighboring bobbin unless the affected spindle is promptly arrested.
  • each of the threads 1 and 1' and individual thread guard shown to comprise a bell-crank lever 3, 3' pivoted at a respective fixed fulcrum 26, 26.
  • each lever 3, 3' is biased for swinging in a counterclockwise direction as indicated by arrows B, B.
  • Such a swing is normally prevented by the tension of the associated thread 1 or 1' which passes through a loop on the free end of the nearly horizontal bell-crank arm, thus holding the vertical arm against a respective stop 17, 17'.
  • Extensions 12 and 12 terminate in cams 13, 13 which, upon a counterclockwise swing thereof as indicated by arrows C, C, lift the respective counterrollers 5, 5' of the associated feeding unit from the corresponding driven rollers 4 and 4' to halt the drawing of further lengths of thread 1, 1' from reels 2, 2'.
  • a plant comprising a twisting station for a plurality of threads and individual feeding units for said threads, the combination therewith of a control member common to said feeding units for concurrently deactivating the latter upon a displacement of said member from a normal to an off-normal position, and a plurality of thread guards respectively positioned adjacent said feeding units for engagement with the threads thereof, each of said thread guards being biased for displacing said mem her into said off-normal position upon a rupture of the thread respectively associated therewith.
  • each of said thread guards comprises a swingable arm having an extremity engageable with said member.
  • said member comprises a generally horizontal bar and a pair of generally vertical links articulated to the ends of said bar for defining therewith a parallelogrammatic linkage, said bar being provided With abutments respectively engageable by the arms of said thread guards.
  • feeding units comprise each a driven roller and a counterroller, said extensions being engageable with said counterrollers for separating them from the corresponding driven rollers.
  • twisting station includes a bobbin winder provided with drive means therefor, further comprising switch means operable by said control member in said off-normal position thereof for arresting said drive means.
