Definitions

  • the present invention relates to a fiber bundle supply interruption device for a spinning machine. More specifically, the present invention relates to a fiber bundle supply interruption device for a spinning machine, which includes a drafting unit and interrupts supply of a fiber bundle to the drafting unit.
  • fine spinning machines that spin a yarn from a roving or a sliver
  • the spinning is simultaneously performed in a plurality of spindles. Even if the yarn is cut during the spinning, the spinning in the spindles other than the spindle in which the yarn is cut continues.
  • the supply of the fiber bundle even to the drafting unit of the spindle in which the yarn is cut continues, and the fiber bundle supplied from the drafting unit is drawn and collected.
  • Some fine spinning machines include an interruption device, which interrupts the supply of the fiber bundle to the drafting unit of the spindle in which the yarn is cut.
  • a stop device in a drafting unit that saves space and is applicable to an existing fine spinning machine is disclosed in Japanese Laid-Open Patent Publication No. 5-195333 .
  • the stop device disclosed in the above publication is formed integrally with an adjustment and load device for raising a top feed roller (top back roller).
  • the stop device is maintained in the state in which the fiber bundle is supplied to the drafting unit in the normal operation state of the spinning machine.
  • the stop device is brought into a state in which the supply of the fiber bundle is interrupted based on yarn-cut signals generated by a sensor when the yarn is cut.
  • the interruption of the supply of the fiber bundle is performed by holding a stop flap at a pressing position, in which the stop flap presses the fiber bundle on a table.
  • a mechanism that moves the stop flap between the pressing position and a retreated position includes an electromagnet controlled based on the yarn-cut signals.
  • the electromagnet is contained in the support arm.
  • a control cable (wiring) is guided from the electromagnet rearward of a machine base through the inside of a support arm and a bracket, which supports the support arm.
  • the above stop device is easily added to an existing fine spinning machine.
  • it is necessary to couple two stop devices to a support arm (weighting arm) of the drafting unit for two spindles. Accordingly, since operations for incorporating two electromagnets into the support arm are needed, the coupling operation is troublesome. Since the wirings required for driving the electromagnets are drawn out of the bracket, which supports the weighting arm, for every two spindles, the wiring operation is also troublesome.
  • An objective of the present invention is to provide a fiber bundle supply interruption device for a spinning machine that is easily added to an existing spinning machine and facilitates wiring.
  • a fiber bundle supply interruption device for a spinning machine includes: a drafting unit; a duct; and a fiber bundle holding mechanism.
  • the drafting unit includes a back roller.
  • the duct has a length that is greater than or equal to a length of four spindles.
  • the fiber bundle holding mechanism is coupled to the duct and holds a fiber bundle to be supplied to the drafting unit at a position rearward from the back roller of the drafting unit.
  • the fiber bundle holding mechanism includes a holding member, which holds the fiber bundle, a biasing member, which biases the holding member from a fiber bundle releasing position to a fiber bundle holding position, and an actuator.
  • the actuator switches the holding member between a state in which the holding member is maintained at the fiber bundle releasing position and a state in which the holding member is released from the maintained state.
  • the duct accommodates wiring required for driving the actuator.
  • the phrase fiber bundle is directed to a fiber bundle that is scarcely twisted, such as of a roving and a sliver.
  • a drafting unit 10 is of a three-pair-roller type configuration, and includes a front roller set 11, an apron set 13 wound around a middle roller set 12, and a back roller set 14.
  • the front roller set 11 is configured by a front bottom roller 11 a and a front top roller 11 b.
  • the middle roller set 12 is configured by a middle bottom roller 12a and middle top roller 12b.
  • a bottom apron member 13a is wound around the middle bottom roller 12a, and a top apron member 13b is wound around the middle top roller 12b.
  • the back roller set 14 is configured by a back bottom roller 14a and a back top roller 14b.
  • the front bottom roller 11 a is supported by a roller stand 15.
  • the middle bottom roller 12a and the back bottom roller 14a are supported by the roller stand 15 through a middle bottom roller supporting portion 16, a back bottom roller supporting portion 17, and a bearing (not shown).
  • the middle bottom roller supporting portion 16 and the back bottom roller supporting portion 17 are fixed to the roller stand 15 such that the positions of the middle bottom roller supporting portion 16 and the back bottom roller supporting portion 17 are adjustable in the front-back direction of the machine (lateral direction in Fig. 1 ).
  • a weighting arm 18 is rotationally supported through a bracket 20 by a pivot 19, which is supported by the roller stand 15.
  • the front top roller 11 b, the middle top roller 12b, and the back top roller 14b are supported by the weighting arm 18 through a top roller supporting portion (not shown).
  • a supporting bar 21 extends along the back bottom roller 14a.
  • a fiber bundle supply interruption device is provided behind the back roller set 14.
  • the fiber bundle supply interruption device is provided such that a fiber bundle holding mechanism 30, which holds the roving S to be supplied to the drafting unit 10 at a position rearward from the back roller set 14, is coupled to the duct 31.
  • the duct 31 has a length that is greater than or equal to the length of four spindles.
  • the duct 31 is formed to have a length sufficient to couple the fiber bundle holding mechanism 30 for twenty-four spindles to the duct 31, for example.
  • the duct 31 is provided along the roller stand 15 in a moveable manner in the front-back direction, and fixed on a coupling member 32.
  • the coupling member 32 is coupled with the back bottom roller supporting portion 17, which supports the back bottom roller 14a, in an integrally moveable manner. That is, the fiber bundle holding mechanism 30 is formed integrally with the back bottom roller supporting portion 17 of the drafting unit 10 in a position adjustable manner.
  • the fiber bundle holding mechanism 30 is provided for each pair of spindles. That is, the fiber bundle holding mechanism 30 is provided for two spindles that form a pair.
  • Two L-shaped supporting boards 33 are each fixed to the upper surface of the duct 31 by a bolt with a hexagon socket. Each holding member 34 is supported by the corresponding supporting board 33 such that the holding member 34 is rotated between a fiber bundle releasing position (position shown in Fig. 2 ) and a fiber bundle holding position (position shown in Fig. 6 ).
  • the fiber bundle holding mechanism 30 includes fiber bundle guides 36.
  • the fiber bundle guides 36 hold the roving S as a fiber bundle in cooperation with the corresponding holding members 34.
  • the fiber bundle guides 36 guide the roving S supplied from a roving spool hung by a creel (not shown) in the state in which the fiber bundle guides 36 do not hold the roving S as a fiber bundle in cooperation with the corresponding holding members 34.
  • each holding member 34 has a cylindrical holding portion body 34a, an L-shaped lever portion 34b in a side view, and a sectoral locked board 34c in a side view.
  • Each lever portion 34b is formed integrally with an end of the corresponding holding portion body 34a, and is located above a supporting shaft 37 (rotation center).
  • Each locked board 34c is located below the supporting shaft 37 (rotation center).
  • Each holding portion body 34a includes a substantially triangular roving holding portion 34d in a side view on an outer circumferential portion of the holding portion body 34a that is away from the supporting board 33.
  • a locking projection 34e is formed on the basal end of each roving holding portion 34d.
  • each holding member 34 is rotationally supported at the holding portion body 34a by the corresponding supporting shaft 37 fixed to the supporting board 33.
  • a torsion spring 38 as a biasing member is externally applied on the basal end of the corresponding roving holding portion 34d of the holding portion body 34a.
  • Each torsion spring 38 plays a role to bias the corresponding holding member 34 from a fiber bundle releasing position to a fiber bundle holding position. In the fiber bundle holding position, each roving holding portion 34d presses the corresponding fiber bundle guide 36.
  • Each torsion spring 38 biases the holding member 34 toward the fiber bundle holding position in the state in which one end of the holding member 34 is fixed to the supporting board 33, and the other end of the holding member 34 is locked by the locking projection 34e. Accordingly, the holding members 34 are maintained at a position in which the roving holding portions 34d hold the roving S in cooperation with the fiber bundle guides 36 in the state free from the application of an external force.
  • Each fiber bundle guide 36 is supported by the corresponding supporting board 33 through a supporting shaft 39, which passes through the fiber bundle guide 36 and is fixed to the supporting board 33.
  • Each fiber bundle guide 36 is formed cylindrical.
  • the fiber bundle holding mechanism 30 is arranged at a position in which the distance between the holding position of the roving S by the holding members 34 and the fiber bundle guides 36 and the nipping position of the roving S by the back roller set 14 is greater than the fiber length of the fibers that configure the roving S.
  • actuators 40 each corresponding to one of the locked boards 34c, are provided between the supporting boards 33.
  • Each actuator 40 switches the corresponding holding member 34 between the state in which the holding member 34 is maintained at the fiber bundle releasing position and the state in which the holding member 34 is released from the maintained state.
  • Each actuator 40 includes a pin 40a and contains a spring, which biases the pin 40a in the protruding direction, and a solenoid.
  • Each actuator 40 is configured such that the pin 40a is drawn into the actuator 40 against the biasing force of the spring in the state in which current flows through the solenoid.
  • Each actuator 40 is provided, in the state in which the holding member 34 is arranged at the fiber bundle releasing position, at a position in which the tip end of the pin 40a enters the hole as a locked portion 42 formed in the locked board 34c and the holding member 34 is maintained at the fiber bundle releasing position.
  • Each actuator 40 is arranged below the weighting arm 18 of the drafting unit 10. As shown in Fig. 3 , the actuators 40 are fixed to the supporting member 41 (not shown in Fig. 5 ) provided between the supporting boards 33.
  • Each locked board 34c is formed such that the locked portion 42 is located at a position in which the locked portion 42 is locked by the pin 40a in the state in which each holding member 34 is arranged at the fiber bundle releasing position.
  • Each locked board 34c is formed in the shape that is locked by the tip end of the pin 40a, which is biased in the direction toward the locking position, in the state in which the holding members 34 are arranged at the fiber bundle holding position, or the state in which the holding members 34 are in the middle position between the fiber bundle releasing position and the fiber bundle holding position.
  • each locked board 34c is maintained in the state in which the tip end of the pin 40a contacts the locked board 34c in the state in which the locked state of the pin 40a and the locked portion 42 is canceled, the holding member 34 is moved from the fiber bundle releasing position, and the actuator 40 is in the non-excited state.
  • a controller C is provided in the duct 31 to check whether the yarn is cut in the spindle based on the yarn-cut signals of the yarn-cut sensor (not shown) and excite the solenoids of the actuators 40 of the fiber bundle holding mechanism 30 corresponding to the spindle in which the yarn is cut to interrupt the supply of the roving S to the spindle in which the yarn is cut.
  • the controller C is connected to main wiring 43, which supplies electric power to excite the solenoids.
  • the solenoid of each actuator 40 is connected through branch wiring 44 to a circuit branched from the power supply for the solenoids through an electric element for exciting the solenoids such as a transistor in the controller C.
  • the solenoids of the actuators 40 are each excited for only a short period required to move the pin 40a to the position in which the locked state of the tip end of the pin 40a and the locked portion 42 of the locked board 34c is cancelled.
  • the controller C is configured to be divided into a plurality of pieces by connecting the devices by the main wiring 43.
  • the holding members 34 are arranged at the fiber bundle releasing position in which the roving holding portions 34d do not hold the roving S.
  • each locked portion 42 of the locked board 34c is locked by the corresponding pin 40a of the actuator 40, and the holding member 34 is maintained at the fiber bundle releasing position.
  • the non-yarn-cut state is directed to not only a state in which the roving S is supplied through the fiber bundle guides 36 to the drafting unit 10 and spun but also a state in which the roving S is not yet supplied to the drafting unit 10 prior to the start of the spinning.
  • the controller C does not determine the yarn is cut even in the state the yarn-cut sensor does not detect the yarn, and the solenoid in each actuator 40 is maintained in the OFF state, i.e., the non-excited state.
  • the roving S supplied from the roving spool hung by a creel is guided by the fiber bundle guides 36 and the trumpet 22 to be supplied to the back roller set 14.
  • the roving S supplied to the back roller set 14 is drafted between the back roller set 14 and the apron set 13 and between the apron set 13 and the front roller set 11 to be a fleece.
  • the fleece becomes a yarn and is wound on a bobbin through a snail wire and a traveler (not shown).
  • the spindle in which the yarn is cut is identified by the detection signals of the yarn-cut sensor (not shown).
  • An excitation current is then supplied from the controller C to the actuators 40 of the fiber bundle holding mechanism 30 corresponding to the spindle in which the yarn is cut for a short period.
  • the pins 40a are each drawn and the locked state of the locked board 34c by the pin 40a is cancelled. Accordingly, the holding members 34 are rotated to the fiber bundle holding position by the effect of the torsion springs 38, and the roving holding portions 34d hold the roving S in cooperation with the corresponding fiber bundle guides 36 behind the back roller set 14 as shown in Fig. 7A .
  • the distance between the holding position by the roving holding portions 34d and the fiber bundle guides 36 and the nipping position of the roving S by the back roller set 14 is less than the fiber length, at least some fibers, which configure the roving S, are subjected to the nipping effect by the back roller set 14 in the state in which the fibers are subjected to the holding effect by the roving holding portions 34d and the fiber bundle guides 36 and the nipping effect by the back roller set 14 simultaneously.
  • a motor which drives the back roller set 14 is likely to be excessively loaded.
  • the back roller set 14 rotates in the state in which the roving S remains stationary. This wears out a rubber cot (not shown), which coats the back roller set 14.
  • the distance between the holding position by the roving holding portions 34d and the fiber bundle guides 36 and the nipping position of the roving S by the back roller set 14 is greater than the fiber length, some fibers, which configure the roving S and are held by the roving holding portions 34d and the fiber bundle guides 36, are not nipped by the back roller set 14. Some fibers, which configure the roving S and are subjected to the nipping effect by the back roller set 14, are not subjected to the holding effect by the roving holding portions 34d and the fiber bundle guides 36.
  • the roving S is moved such that the fibers, which are not held by the roving holding portions 34d and the fiber bundle guides 36, are subjected to the nipping effect by the back roller set 14 to be drawn out from a group of the fibers. This cuts the roving S without increasing the torque of the back roller set 14.
  • the distance between the holding position by the roving holding portions 34d and the fiber bundle guides 36 and the nipping position of the roving S by the back roller set 14 is excessively greater than the fiber length, the distance between the nipping point by the back roller set 14 and the end of the roving S is excessively long when the roving S is cut between the back roller set 14 and the fiber bundle holding mechanism 30 so that the roving S is likely to be wound around the back bottom roller 14a. Accordingly, it is preferable that the distance between the holding position by the roving holding portions 34d and the fiber bundle guides 36 and the nipping position of the roving S by the back roller set 14 be less than the circumferential length of the back bottom roller 14a.
  • the actuators 40 are excited for a short period. This draws each pin 40a to cancel the locked state of the locked board 34c by the pin 40a. This rotates the holding members 34 such that the roving holding portions 34d move toward the fiber bundle holding position. The excitation of the actuators 40 is cancelled in the middle of the rotation of the holding members 34 so that the pins 40a are each brought into contact with the corresponding locked board 34c. The pins 40a are each maintained in contact with the locked board 34c even in the state in which the roving holding portions 34d are each arranged at the fiber bundle holding position.
  • the lever portions 34b of the holding members 34 are manipulated by the operator or an automatic yarn piecing device so that the holding members 34 are arranged at the fiber bundle releasing position against the biasing force of the torsion springs 38.
  • the pins 40a are maintained in contact with the corresponding locked boards 34c. Accordingly, the manipulation of the lever portions 34b smoothly rotates the holding members 34 to the fiber bundle releasing position.
  • the locked portions 42 of the locked boards 34c face the corresponding pins 40a and the tip ends of the pins 40a lock the corresponding locked portions 42.
  • the fiber bundle holding mechanism 30 is arranged at a predetermined position of the spinning machine in the state in which the fiber bundle holding mechanism 30 is coupled to the duct 31. Accordingly, before coupling the duct 31 to the spinning machine, a plurality of the fiber bundle holding mechanisms 30 are coupled on the duct 31 such that the holding members 34 are arranged at an interval of the length of the spindle. The duct 31 is then coupled to the spinning machine. This facilitates the coupling of the fiber bundle holding mechanism 30 to the spinning machine more than in the case in which the fiber bundle holding mechanism 30 is directly coupled to the spinning machine without providing the duct 31.
  • the position of the back roller set 14 is adjusted once or twice per year. If the position of the back bottom roller 14a is adjusted, it is also necessary to adjust the position of the fiber bundle holding mechanism 30.
  • the duct 31 is fixed on the coupling member 32 coupled to the back bottom roller supporting portion 17 in the integrally movable manner.
  • the back bottom roller supporting portion 17 supports the back bottom roller 14a. Accordingly, the position adjustment of the fiber bundle holding mechanism 30 is performed integrally with the back bottom roller 14a of the drafting unit 10. As a result, it is not necessary to especially perform the position adjustment of the fiber bundle holding mechanism 30.
  • the present invention is not limited to the above embodiment.
  • the embodiment may be modified as follows, for example.
  • the fiber bundle may be of not only the roving S but also the sliver.
  • a fiber bundle supply interruption device may be used for a ring fine spinning machine that spins yarn from a sliver using a drafting unit that drafts a fiber bundle by far greater drafting ratio than in a normal drafting unit with three pairs of rollers as a drafting unit.
  • the spinning machine is not limited to the ring fine spinning machine.
  • the spinning machine may be a bundle spinning machine or a friction spinning machine, for example.
  • the spinning machine may be a roving frame.

  • the positions of the actuators 40 are not limited to the position below the weighting arm 18.
  • the actuators 40 may be arranged below the roving passage.
  • each fiber bundle holding mechanism 30 is not limited to the configuration of the two spindles.
  • each fiber bundle holding mechanism 30 may be configured to be independently coupled to the duct 31 for each spindle.

  • the holding members 34 may be configured such that a weight is provided for biasing each holding member 34 toward the fiber bundle holding position or the weight of the holding members 34 biases the holding members 34 toward the fiber bundle holding position.
  • the holding members 34 are not limited to the configuration in which the holding members 34 are rotationally provided between the fiber bundle releasing position and the fiber bundle holding position.

  • the configuration in which the fiber bundle holding mechanism 30 is formed integrally with the back bottom roller 14a of the drafting unit 10 in a position adjustable manner is not limited to the configuration in which the duct 31 is fixed on the coupling member 32 coupled with the back bottom roller supporting portion 17 in a position adjustable manner.

  • the supporting boards 33 of the fiber bundle holding mechanism 30 may be configured to be coupled on the duct 31 via the coupling member 32, which is coupled to the back bottom roller supporting portion 17 in an integrally movable manner.
  • the duct 31 may be fixed to a coupling member from the roller stand 15 or the pivot 19. That is, the fiber bundle holding mechanism 30 need not be formed integrally with the back bottom roller supporting portion 17 of the drafting unit 10 in a position adjustable manner.
  • the shape of the duct 31 is not limited to a tetragonal tube-like.
  • the shape of the duct 31 may be of any shape, for example, a pentagonal tube-like or a hexagonal tube-like as long as the duct 31 can be supported by the roller stand 15 and the fiber bundle holding mechanism 30 can be coupled to the duct 31.
  • Holding members that hold the roving S in cooperation with the holding members 34 may be provided separately from the fiber bundle guides 36.
