Definitions

  • Lavine ABSTRACT A device which automaticall tension including a lever upon which resulta 57/80 and which forces are counterbalanced D0lh 13/16 tion of the lever: a spindle brake actu 57/78, 80, position until released by lever movement occasioned 79, 81 breakage.
  • the invention device is intended to render more efficient the operation of a spinning frame and twisting machine by decreasing the yarn breakage.
  • the invention device facilitates in great measure an operation of the spinning frame and decreases the required number of operators in relation to the number of spindles operated.
  • the invention device has the advantage over the prior art that regulation of the yarn tension in twisting zone takes place automatically, but not mechanically.
  • a strict adjustment of position of the yarn guide to the spindle head was very difficult and practically impossible, because of frequent changes in quality of the yarn processed as well as various conditions at each individual spindle dependent upon the momentary state of the ring, traveler, bobbin, etc.
  • the sensing device automatically regulates the yarn tension in relation to the general conditions at the spinning frame and according to conditions at each individual spindle.
  • the action of the sensing device is as follows: In the case of a decrease in the yarn tension at the yarn twisting section, i.e. between delivery rollers and yarn guide, the sensing device swings forward causing a lifting of the yarn guide and an automatic increase in the yarn tension.
  • the increase of the yarn tension causes the sensing device to return to the initial position or to move to a new position-suited to the momentary conditions.
  • the invention device protects particularly against decrease of the yarn tension below the operational limit, when it would cause the yarn to wind on the spindle below the spindle head and consequently cause yarn breakage.
  • sensing device is in the caseof yarn breakage; the sensing device through a lever arrangement of the device causes an automatic braking of the spindle, which prevents the fraying of the free end of the broken yarn.
  • FIG. 1 shows a side view of the sensing device of the spinning frame and parts of the spinning machine.
  • FIG. 2 shows an alternative construction of the sensing device, operating with a solenoid.
  • FIG. 3 shows a horizontal cross section of the spring, which guides and supports the pull rod operating the brake.
  • FIG. 4 shows the sensing device of FIG. 1 together with the yarn guide in side view, at an enlarged scale.
  • the weight arrangement of yarn guide 3 and sensing device 4tightly connected to each other is such that the center of gravity of the assembly is on the right side of the vertical plane passing through the axis 2, and thus creates force G in the system of forces.
  • the force G is balanced by the forces S and S the magnitudes of which are related to the yarn tension S of the yarn 14.
  • force S decreases, force S also decreases and in consequence of force G causes the assembly to turn in the clockwise direction.
  • Swinging forward the yarn guide 3 from position I to position II results in increase of the yarn tension S, and at the same time in increase of the force 5,, and decrease of the angle a, which makes a further increase of force 5.
  • the yarn guide 3 together with sensing device 4 move in the opposite, counterclockwise direction thereby causing an oscillating movement of the assembly till the balance has been attained.
  • the yarn guide 3 together with sensing device 4 are mounted on the small flap 5, which is nonrotatably mounted on the shaft 6 and is supported by bracket 7 which is fastened tightly to the shaft 6.
  • the sensing device 4 When the yarn 14 breaks, the sensing device 4 together with the yarn guide 3 rotates in the clockwise direction as a consequence of the action of force G and because of kinetic energy strikes the push rod 8.
  • the released pull rod 12 is pressed by the spring 13 so that it is contacted by a continuously oscillating lever 15, which is moved by machine-driven gearing.
  • the end of lever 15 engages the catch 16 of the pull rod 12 and pulls it up to cause braking of spindle l.
  • the supporting lever 10 can return to its original position in consequence of greater weight of its right arm than of its left arm. Besides turning, respectively, bundling of the yarn 14 leads itself through the yarn guide 3 and sensing device 4 which return to the working position and release the pressure of the pushbutton 8 on the lever 10, which goes into a position supporting the pull rod 12. After disengagement of the spindle brake, the pull rod 12 drops, goes into contact with the spring 13 and rests on the lever 10 and activated spindle 1 permits the fixing of the yarn and resumption of normal work.
  • FIG. 2 shows the second alternative solution in which impulse from the sensing device 4 on the lever 10" is transmitted by means the solenoid 18.
  • a device for automatically regulating yarn tension and for automatically braking the spindle in a ring spinning and ring twisting machine comprising a yarn guide above a spindle and a sensing device having a first part engaged by the yarn and a second part secured to said yarn guide, means supporting said guide and sensing device for rotational movement, at least part of the weight of said guide and sensing device producing a moment which counterbalances moments produced on said guide and device by the tension of the yarn.
  • the device of claim 1 and further comprising means for actuating a spindle brake, and means for'releasing said actuating means in response to excess movement of said guide and sensing device upon yarn breakage.
  • said actuating means comprising a spring-urged lever
  • said releasing means comprising holding means engaging said lever for preventing movement thereof, and means engageable by said guide and sensing device for releasing said holding means.
  • said holding means comprising a lever.
  • said spring-urged lever comprising means engageable by said oscillating lever upon movement thereof into the path of said oscillating lever.
  • said releasing means comprising a solenoid, a switch engageable by said guide and sensing device, and a circuit connecting said solenoid and switch.
