Definitions
- a second magnet biases the detector against the yarn and rapidly displaces the detector to switch-closing position in response to yarn breakage.
- An electromagnet returns the detector to initial positionwith a delay following yarn breakage.
- the present invention relates to yarn spinning machines in general, and more particularly to improvements in an apparatus for regulating the operation of spinning machines. Still more particularly, the invention relates to an apparatus which can detect breakage of yarn in ringless and analogous spinning machines and which can interrupt the feed of yarn in response to detection of breakage.
- Another object of the invention is to provide a novel detector which can be used in the improved apparatus and to construct and assemble the detector in such a way that it can produce or initiate the generation of satisfactory signals whenever it detects a break in the yarn and irrespective of the presence and quantity of solid or other impurities in the surrounding atmosphere.
- a further object of the invention is to provide a fully automatic regulating apparatus which can be installed in known ringless and other spinning machines and which requires no attention on the part of the operating personnel.
- An additional object of our invention is to provide a regulating apparatus which occupies little room, which 3,404,524 Patented Oct. 8, 1968 comprises a relatively small number of simple and rugged components, which can restart a spinning machine when the break in the yarn is eliminated, and which consumes little energy.
- the apparatus comprises driven rolls or analogous advancing means for moving the yarn from the producing station lengthwise in a predetermined direction and in a predetermined path so that the yarn is maintained under tension, control means operative to terminate the movement of yarn in the predetermined direction and including switch contacts at least one of which is movable with reference to the other contact in response to placing into a suitable magnetic field to thereby trigger the operation of the control means, an envelope arranged to shield the contacts from foreign matter and to thus insure proper operation of the control means irrespective of the quantity of foreign matter in the surrounding atmosphere, detector means movable from a first position of engagement with the yarn in the aforementioned path when the yarn is under requisite tension to a second position when the tension is relaxed, for example, due to yarn breakage, and magnet means movable with the detector means and arranged to move the one contact with reference to the other contact in the second position of the detector means.
- the two contacts movable from a first position of engagement with the yarn in the aforementioned path when the yarn is under requisite tension to a second position when the
- the apparatus preferably further comprises an accelerating device which permanently urges the detector means to second position, i.e., which biases the detector means against the yarn.
- the control means preferably includes a Brief description of the drawing FIG. 1 is a diagram showing the component parts of a ringless spinning machine whose operation is regulated by the apparatus of our invention.
- FIG. 2 is a perspective view of the regulating apparatus.
- FIG. 1 there is shown a diagram of a ringless spinning machine which comprises a spinning unit 1 including a separating mechanism 2 and a yarn forming unit 3.
- the yarn 4 is conveyed upwardly in a vertical path defined in part by a suction tube 16 (see FIG. 2) and its tension is tested by a detector unit 5 in a manner to be fully described in connection with FIG. 2.
- the means for advancing the yarn upwardly comprises a pair of advancing rolls 6 at least one of which is driven, and the yarn is taken up by a driven bobbin 7 located at a level above the rolls 6.
- the spinning unit 1 further comprises a series of drives including a drive 8 which feeds the sliver 9 from a source 10, a drive 11 which operates the separating 3 mechanism 2, and a drive 12 for the yarn forming unit 3.
- the latter preferably comprises a conventional spinning chamber which is maintained at subatmospheric pressure, together with the interior of the tube 16.
- the operation of the drive 8 is regulated by a control unit 13 which receives signals from the detector unit 5.
- the control unit 13 further regulates the operation of a reversible drive 14 for the advancing rolls 6 and the operation of a reversible drive 15 for the bobbin 7.
- the detector unit and certain parts of the control unit 13 are shown in greater detail in FIG. 2.
- the detector unit 5 comprises a main support or frame 35 which carries the aforementioned suction tube 16.
- the upper end of the tube 16 is spaced from a yarn guide 18 which is provided on the frame 35 and guides the yarn 4 at a level below the advancing rolls 6.
- the detector unit 5 further comprises a detector means or sensor 17 which resembles a lever and is rockable on a horizontal pivot pin 36. Its bent-over upper end portion 19 engages and bears against the yarn 4 between the upper end of the suction tube 16and the guide 18.
- the end portion 19 of the sensor 17 is biased against the yarn 4 by an accelerating device including a permanent magnet 24 installed on the frame 35 and a magnetiz-able member 22 which is rigid with the sensor 17.
- the member 22 constitutes the lower arm of a two-armed lever 20 which is rockable on the pin 36 and whose upper arm 21 constitutes the armature of an electromagnet 23 affixed to the frame 35.
- the lever 20 consists of ferromagnetic material.
- the electromagnet 23 When the electromagnet 23 is energized, it attracts the arm 21 and causes the sensor 17 to return to the normal or operative position of FIG. 2 in which its upper end portion 19 can engage the yarn 4 while the latter is under normal tension.
- the electromagnet 23 is stronger than the magnet 24 but the latter takes over as soon as the sensor 17' returns to the position of FIG.
- the sensor 17 carries a permanent magnet 26 which serves as a means for closing an electric switch in response to movement of the sensor 17 to second position. The latter can assume such second position when the yarn 4 breaks or its tension decreases sufficiently so that the magnet 24 can rapidly attract the arm 22 and propels the end portion 19 toward and into abutment with the cushion 30.
- the aforementioned switch forms part of an electric circuit in the control unit 13 and comprises two normally spaced electric contacts 25 at least one of which moves into current-conducting engagement with the other contact when placed into a magnetic field of requisite strength.
- Such field is produced by the permanent magnet 26 and its intensity is sufficient to close the switch when the end portion 19 of the sensor 17 abuts against the cushion 30, i.e, when the yarn 4 breaks.
- the contacts 25 are shielded by an envelope 25a of vitreous or other suitable material so that the closing and/ or opening of the switch is not affected by the presence of dust or other foreign matter in the space surrounding the envelope 25a. All that counts is to move the magnet 26 sufficiently close to the envelope 25a to effect closing of the switch contacts 25 whereby the control unit 13 automatically arrests the drive 8 and reverses the drives 14, 15, i.e., the upward movement of broken yarn 4 is arrested and the rolls 6 begin to feed the yarn backwards.
- the arrangement is such that the trailing portion of the yarn is still located in the suction tube 16 when the sensor 17 assumes the second position in which the contacts 25 are closed.
- Conductors 27, 29 connect the switch contacts 25 in circuit with a signal lamp 28 which lights up when the sensor 17 moves to second position.
- the lamp '28 can be replaced by a bell or another suitable signal generating device.
- a source of electrical energy for the control unit 13 is shown at 37.
- the electromagnet 23 is connected in series with the switch contacts 25 so that it is energized in response to movement of the yarn-engaging portion 19 into abutment with the cushion 30. Energization of electromagnet 23 can be timed by a suitable time delay relay or the like to provide time for reversal of drives 14, 15 and return movement of yarn 4 toward the unit 3.
- the drive 8 advances sliver 9 from the source 10 and the drives 14, 15 are operative to cause upward movement of yarn 4, such yarn being taken up by the bobbin 7.
- the magnet 24 attracts the lower arm 22 of the lever 20 so that the upper end portion 19 of the sensor 17 bears against the yarn between the suction tube 16 and yarn guide 18 and the yarn is strong enough to withstand such bias and to prevent movement of the end portion 19 into abutment with the cushion 30.
- the lower arm 22 of the lever 20 is accelerated by the magnet 24 and propels the upper end portion .19 of the sensor 17 against the cushion 30 even before the trailing end of the yarn leaves the suction tube 16.
- the magnet 26 closes the switch contacts 25 because the sensor 17 has assumed its second position and the signal lamp 28 lights up.
- the end portion 19 urges the yarn against the cushion 30 to arrest its forward movement. Closing of switch contacts 25 produces a signal which causes the control unit 13 to arrest the drive 8 and to reverse the drives 14, 15.
- the electromagnet 23 is energized and attracts the upper arm 21 of the lever 20 against the opposition of the permanent magnet 24 so that the end portion 19 of the sensor 17 releases the yarn 4 and such yarn can travel downwardly.
- the operation of the drive 12 is not dependent on the position of the contacts 25, i.e., the interior of the tube 16 remains under suction and the yarn is drawn back into the unit 3 and its trailing end is placed onto the aforementioned collecing surface of the unit 3.
- the collecting surface then attracts the yarn.
- the contacts 25 are opened when the collecting surface already holds the trailing end of the yarn, and such opening of contacts 25 causes the control unit 13 to start the drive 8 and to reverse the drives 14, 15.
- the drive 11 operates continuously.
- the yarn 4 is tensioned as soon as the rolls 6 begin to rotate in a sense to move the yarn toward the bobbin 7.
- the magnet 24 attracts the arm 22 and the end portion 19 of the sensor presses an intermediate portion of the yarn 4 against the cushion 30. A portion of the yarn remains in the tube 16.
- the yarn can be released in response to short-lasting energization of the electromagnet 23.
- the duration of such energization is determined by a time-delay relay in the circuit of the control unit 13.
- the purpose of clamping the yarn against the cushion 30 when the spinning machine is idle is to prevent complete extraction of yarn from the tube 16 and to permit for automatic splicing of yarn on restarting of the machine. Manual threading of yarn through the tube 16 and into the unit 3 is a time-consuming operation.
- the signal lamp 28 is of particular importance if the machine is not provided with the aforedescribed auto-.
