Definitions

  • Heating devices with heating surfaces over which the threads to be treated are guided are common in many, diverse types of processing stages of yarn production and yarn treatment, e.g., in stretching, stretch-winding, stretch-twisting, texturizing or stretch-texturizing operations.
  • Usual forms of such heating devices are socalled heating plates, over whose arched heating surface the threads run, and slotted heating tubes, in-
  • the thread applying device described in German Gbm. No. 1,958,183 may still function.
  • the height adjustment of the thread run-over roller is accomplished in this patent by hand, i.e., by means of a push rod, on the upper end of which there is fastened the deflection roller.
  • the maximal stroke and thereby the maximal heating plate length therefore, are limited by the dimensions of the human body (body size and extendable arm length).
  • the known device does not permit in the thread applying the optical checking of the applying process itself, since the applying device as mounted at the heating place on the heating face side blocks the view.
  • the thread applying operation is surely and rapidly achieved on heating devices, namely, those having a length of several meters, e.g., 2 to 5 meters.
  • the thread is applied to the heating surface only when all the thread guiding elements are completely in operation.
  • the thread applying operation is brief in order to avoid relatively great waste windings. Further, in case of irregularities or malfunctions, the thread applying operation can be stopped immediately.
  • a thread applying device of the type mentioned above which is characterized by a guide member positioned beside the heating device and running substantially vertically, a slide piece vertically adjustable on it, on whose horizontally swingable arm is supported the thread run-over member, and a drive for the moving of the slide piece up and down.
  • the thread applying device is arranged beside and not as in the known state of technology on face side in front of the heating surface, the heating surface can always be well observed during the applying process.
  • the arm carrying the thread run-over member is swung, not vertically, but horizontally away from the heating surface and toward it, there is simultaneously achieved a large gain in space.
  • the guide member as a profiled rod or rail, on which a slide piece with mating counter-profile is guided.
  • Drive and swingable movement of the arm with the thread run-over member are possible in many ways.
  • the guide member is a pipe, which is surrounded by a slide piece and has in its interior a piston connected via a cable with the arm of the slide piece, which piston is preferably elevationally adjustable pneumatically by operation of a valve.
  • the guide member is a pipe, which is surrounded by a slide piece and has in its interior a piston connected via a cable with the arm of the slide piece, which piston is preferably elevationally adjustable pneumatically by operation of a valve.
  • the slide piece In order to carry out the swinging of the arm, it is possible, for example, for the slide piece to be rotatable about the pipe.
  • the guide member e.g., the tube
  • the arm is swung away from the heating surface, for example through 45 to and driven down by the drive to a height at which the operating personnel can conveniently reach the thread run-over member.
  • the device becomes especially simple if as preferred the piston is movable upward pneumatically and movable downward by reason of its own weight. In this manner the supplying of a pneumatic pressure to the undersurface ofthe piston suffices during the travel upward. For the driving down of the piston it suffices to release the pressure i.e., the piston need be acted upon on only one side of its sides. This leads to a simplification of the pneumatic conduit system. Through the size of the piston weight it is possible, furthermore, to achieve a clearly defined path-time function.
  • This arrangement is preferred to a further conception of this invention in which the piston is acted upon only from above when the slide piece is to be raised.
  • the system of slide-piece-arm-thread run-over member has to have a sufficiently great mass to be able to raise the piston again.
  • the piston is movable pneumatically both upward and downward.
  • FIG. 1 is a front elevation of the preferred embodiment of the thread-applying device of the invention in operating position
  • FIG. 2 is a top plan and section view of the embodiment of FIG. 1, as seen from section 2-2, and illustrates simultaneously the swinging range of the threadapplying device.
  • a thread run-over roller or pulley 5 is mounted on the free end of the arm 4, which, in turn, is connected to the slide piece 3.
  • the slide piece 3 embraces the pipe 8 with the latter serving as guide member 2.
  • the connection between the arm 4 and the counterweightpiston 7, which is movable vertically in the interior 9 of the pipe 8, is by the cable 10.
  • the cable 10 reverses its direction as it passes across the roller or pulley 16. In upward movement of the piston 7, the slide piece 3 moves downward in the same degree, and in downward movement of the piston 7 the slide piece 3 is raised correspondingly.
  • the pipe 8 serving as guide member 2 is constructed a rectangular, four-corner pipe. It is borne by means of two pivots 17 and 17" at its ends, so that the pipe can rotate about its vertical axis 11. Rotation of the pipe 8 brings about the horizontal swinging, according to the invention, of the arm 4 and its thread run-over member 5.
  • the pivots 17 are drilled axially, the cable being conducted through the upper pivot 17', while through the lower pivot 17 passes the feed line 18 for the pneumatic pressure medium, which acts on the underside of the piston 7.
  • the piston is acted upon only on one side with air or the like when it is brought to the top.
  • the piston 7 is constructed as an adequately great counterweight, which is in a position to move the slide piece 3 with arm 4 and thread run-over pulley or roller 5 upward against all the frictional forces.
  • the piston 7 otherwise keeps, by gravity, the slide piece 3 in its upper operating position.
  • a second air pressure line 180 with valve 6a may be connected similarly to the upper portion of the pipe 8.
  • the thread F coming from a supply (not represented), is wound a number of times around the stretching godet 12 and its deflection roller 13, guided over the lowered thread run-over roller or pulley 5, guided through the false-twist assembly 15 (schematically represented) and wound on a ring-twist device (not represented).
  • the thread running speed is allowed to increase to the value desired in operation, thus, for example, 800 m/min, and the pneumatic system is then taken out of operation.
  • the piston 7 then descends, following its path-time function, to a lower stop, the slide piece 3 going into the highest position, i.e., the operating position.
  • the arm 3 By swinging back the arm 3, i.e., by turning the pipe back through about 45 to 120, the thread F running with full speed is applied to the heating surface of the heating plate or tube 1, which in the present example has a length of 2.5 meters.
  • the arresting device 14 then holds the arm 4 in operating position.
  • the pipe 8 used preferably can be standard size.
  • the piston 7 can be a correspondingly prefiled iron or steel bar or rod.
  • coarse tolerances are sufficient.
  • the entire thread-applying device is most simple and cheap to produce.
  • the pipe 8 and the slide piece 3 there can be used, for example, circular pipes, although polygonal cross sections are preferred. With the latter, the turning of the pipe 8 about its axis 11 brings about a defined swinging of the arm 4.
  • a square cross-section pipe and a square crosssection slide piece have been used.
  • a device for applying rapidly running threads to heating surfaces which comprises a heating surface, a substantially vertical guide member positioned beside said heating surface, a slide piece slidable on said guide member, a horizontal arm on said slide piece, a thread run-over member on said arm, turning means for swinging said arm and its run-over member in a horizontal are, and drive means for moving said slide piece up and down along said guide member.
  • said guide member being a pipe
  • said slide piece being fitted about said pipe, a piston inside said pipe and connected via a cable with said arm of said slide piece, and means for moving said piston longitudinally in said pipe.
  • said turning means including said guide member, and means mounting the latter for rotation about its vertical axis.
  • said drive means being pneumatic means for pushing said piston upwardly by pneumatic pressure in said pipe, and said piston returning downward by reason of its own weight upon release of said pressure.
  • said drive means being pneumatic means for forcing said piston pneumatically both upward and downward.
