Definitions

  • the present invention relates to textile machines. More specifically, the present invention relates to laying of pipes for supplying a working fluid in the textile machines.
  • a compressed air is supplied to various structural components of the textile machines, and these structural components are driven by the compressed air.
  • a swirling airflow is generated by the compressed air, and untwisting and joining of a yarn is performed by the swirling airflow.
  • acts such as removal of a waste yarn by an air blast (blowing of compressed air), and driving of the structural components by driving corresponding air cylinders are performed.
  • Typical textile machines also include structural components to which a driving force is transmitted via mechanical means such as cams or linkage mechanisms instead of the compressed air.
  • mechanical means such as cams or linkage mechanisms
  • pipes for supplying the compressed air and the mechanical components such as the cams or the linkage mechanisms are also arranged in a space inside a body of the textile machines.
  • a maintenance operation needs to be performed periodically of the control boards arranged inside the body of the textile machines. It is therefore preferable that pipe laying be performed and structures for installing the pipes be arranged by taking into consideration the maintainability. For example, there is a need to lay the pipes in such a manner that the pipes do not hinder the maintenance operation of the control boards.
  • Pipes made of an elastic material such as resin or rubber are advantageous from the view point of flexibility; however, disadvantageous from the view point of having greater chances of generation of defects such as kinks. Therefore, pipe laying needs to be performed in such a manner that kinks are not generated in the pipes without discretion during the maintenance operation of the control boards.
  • Japanese Patent Application publication 2001-106434 discloses a technology for enhancing maintainability of a textile machine having air pipes.
  • Japanese Patent Application publication 2001-106434 discloses a winding unit that can be moved during an inspection for maintenance. Specifically, an end of an air pipe is detachably coupled to the winding unit via a coupling. A flexible pipe is used as the air pipe in Japanese Patent Application publication 2001-106434 for easy detachment and coupling.
  • the winding unit disclosed in Japanese Patent Application publication 2001-106434 has a closing piece to preclude variations in an air pressure in other winding unit even when the pipe is detached from the winding unit. Because the pipe can be easily detached or coupled by adapting this configuration, the inspection for maintenance can be performed smoothly.
  • Japanese Patent Application publication 2001-106434 makes it possible to move the winding unit to a position where the inspection for maintenance can be performed easily, and this object is achieved with a configuration in which the pipe is detachably coupled.
  • Japanese Patent Application publication 2001-106434 does not specifically mention about handling of pipes (pipe laying) inside the winding unit. That is, the configuration disclosed in Japanese Patent Application publication 2001-106434 cannot solve the issues that arise in the maintenance of internal parts of the winding unit such as hindrance caused by an air pipe, generation of kinks in the air pipe, etc.
  • the present invention has been made to address the above-explained problems. It is an object of the present invention to enhance maintainability while preventing generation of kinks in a pipe that supplies a working fluid in textile machines.
  • a textile machine that includes a unit body member; a structural component arranged in or near the unit body member; a pipe made of an elastic material and configured to supply a working fluid to the structural component; compartment members that partition an inner space of the unit body member; and pipe arrangement compartments formed due to partitioning of the inner space of the unit body member by the compartment members, wherein, inside the unit body member, the pipe is laid in the pipe arrangement compartments.
  • FIG. 1 is an external perspective view of an automatic winder according to an embodiment of the present invention.
  • An automatic winder (textile machine) 1 according to the present embodiment includes a plurality of winder units 2 that is arranged in a line and a main control device 3 arranged at one end of the line.
  • Each of the winder units 2 includes a unit body member 4 provided on either a left or a right side when viewed from a front side and various structural components (an unwinding assisting device 12, a tension applying device 13, a splicer device 14, a clearer 15, a cradle 23, a traversing drum 24, a lower yarn guiding pipe 25, an upper yarn guiding pipe 26, etc., shown in FIG. 2 ) attached to a lateral side of the unit body member 4.
  • various structural components an unwinding assisting device 12, a tension applying device 13, a splicer device 14, a clearer 15, a cradle 23, a traversing drum 24, a lower yarn guiding pipe 25, an upper yarn guiding pipe 26, etc., shown in FIG. 2 ) attached to a lateral side of the unit body member 4.
  • FIG. 2 depicts a schematic side view of the winder unit 2. As shown in FIG. 2 the winder unit 2 includes a bobbin support unit 7 and a winding unit 8.
  • the bobbin support unit 7 includes a bobbin holding peg 9.
  • the bobbin holding peg 9 is inserted in a yarn supplying bobbin 21 from an axis direction of a core tube of the yarn supplying bobbin 21 and holds the yarn supplying bobbin 21 in a substantially upright posture.
  • the bobbin holding peg 9 can be tilted by an action of a not shown motor.
  • the yarn supplying bobbin 21 that is held in the upright posture can be discharged by tilting the bobbin holding peg 9.
  • the winding unit 8 includes the cradle 23 and the traversing drum 24.
  • the winding unit 8 winds a yarn 20 around a periphery of a winding bobbin to produce a package 29.
  • the cradle 23 includes a cradle arm 23a that holds the package 29.
  • a center bearing 22 is arranged at an end of the cradle arm 23a, and the package 29 is rotatably supported by the center bearing 22.
  • the traversing drum 24 is arranged opposed to the package 29, and the traversing drum 24 is rotationally driven by the action of a not shown motor.
  • the package 29 is dependent driven following the rotation of the traversing drum 24. Therefore, by driving the traversing drum 24, yarn unwound from the yarn supplying bobbin 21 can be wound on a surface of the package 29.
  • a not shown traversing groove is formed on a peripheral surface of the traversing drum 24, and the yarn 20 can be traversed for a predetermined width on the peripheral surface of the traversing drum 24 by an action of the traversing groove.
  • the cradle 23 is swingable around a swing axis 23b. Even when the package 29 becomes thicker due to winding of the yarn 20, the surface of the package 29 can be appropriately maintained in contact with the traversing drum 24 by swinging the cradle 23 around the swing axis 23b.
  • a package pressure cylinder 81 is coupled to the cradle 23.
  • the package pressure cylinder 81 is a pneumatic cylinder and it can be operated by the action of a compressed air.
  • the cradle arm 23a can be swung in a clockwise direction or an anticlockwise direction with respect to the swing axis 23b.
  • a contact pressure (a pressing force by which the package 29 is pressed against the traversing drum 24) of the package 29 can be appropriately adjusted.
  • the cradle arm 23a can also be swung so as to separate the package 29 from the traversing drum 24.
  • the rotating package 29 can be promptly brought to a halt.
  • the package brake mechanism is arranged at an end of the cradle arm 23a.
  • the package brake mechanism includes a not shown brakeshoe and a not shown brake cylinder that operates the brakeshoe so as to press the brakeshoe against the center bearing 22.
  • the brake cylinder is a pneumatic cylinder and it can be operated by the action of the compressed air. When the brake cylinder is operated, the brakeshoe is pressed against the center bearing 22, and the center bearing 22 comes to a halt due to a frictional force. Thus, by operating the package brake mechanism, the rotating package 29 that is held by the cradle 23 can be promptly brought to a halt.
  • the winder unit 2 includes, in a yarn running path, near the unit body member 4, various structural components between the bobbin support unit 7 and the winding unit 8.
  • the unwinding assisting device 12, the tension applying device 13, the splicer device 14, and the clearer (a yarn quality measuring device) 15 are arranged in the yarn running path from the bobbin holding peg 9 to the traversing drum 24.
  • the unwinding assisting device 12 causes a movable member 76 to touch a balloon that is formed above the yarn supplying bobbin 21 due to spinning of the yarn being unwound from the yarn supplying bobbin 21.
  • the unwinding assisting device 12 thus assists the unwinding of the yarn by appropriately controlling a size of the balloon.
  • a position of formation of the balloon varies depending on an amount of yarn remaining on the yarn supplying bobbin 21. Therefore, the unwinding assisting device 12 includes an unwinding assisting device cylinder 82 for moving the movable member 76 down depending on the amount of remaining yarn.
  • the unwinding assisting device cylinder 82 is a pneumatic cylinder and it is operated by the action of the compressed air. Unwinding of the yarn from the yarn supplying bobbin 21 can be properly performed by moving the movable member 76 down to an appropriate position and then appropriately operating the unwinding assisting device cylinder 82.
  • the tension applying device 13 applies a predetermined tension to the running yarn 20.
  • the tension applying device 13 according to the present embodiment is a gate type in which movable comb teeth are provided with respect to fixed comb teeth.
  • the movable comb teeth can be rotated by the action of a rotary solenoid so as to be engaged with or released from the fixed comb teeth.
  • the clearer 15 detects yarn defects (yarn faults) such as a slub by monitoring a thickness of the yarn 20.
  • a cutter 39 that cuts the yarn 20 immediately upon detection of a yarn defect by the clearer 15 is arranged near the clearer 15.
  • the splicer device 14 splices a lower yarn on the yarn supplying bobbin 21 side and an upper yarn on the package 29 side in any of the situations of a yarn cut, a yarn break, and a bobbin replacement.
  • the yarn cut is a situation where the yarn is cut by the cutter 39 upon detection of a yarn defect by the clearer 15, the yarn break is a situation where the yarn breaks while being unwound from the yarn supplying bobbin 21, and the bobbin replacement is a situation where an old yarn supplying bobbin is replaced with a new yarn supplying bobbin.
  • the splicer device 14 first untwists ends of the upper and lower yarns by blowing the compressed air onto the ends, causes the untwisted ends of the yarns to come closer to each other, and then joins the ends by twisting the ends together by generating a swirling airflow in an opposite direction.
  • the lower yarn guiding pipe 25 traps and guides the lower yarn on the yarn supplying bobbin 21 side
  • the upper yarn guiding pipe 26 traps and guides the upper yarn on the package 29 side.
  • a suction port 32 is provided at an end of the lower yarn guiding pipe 25, and a suction mouth 34 is provided on an end of the upper yarn guiding pipe 26.
  • a negative-pressure source is appropriately connected to each of the lower yarn guiding pipe 25 and the upper yarn guiding pipe 26, and a suction airflow is caused to act on the suction port 32 and the suction mouth 34.
  • the lower yarn is suction trapped by rotating the lower yarn guiding pipe 25 such that the suction port 32 locates downward, and then the lower yarn guiding pipe 25 is rotated around an axis 33 such that the lower yarn is guided to the splicer device 14.
  • the upper yarn guiding pipe 26 is rotated upward around an axis 35 from its position in FIG. 2 , and the package 29 is rotated in a reverse direction to its normal rotation direction, thereby trapping the upper yarn unwound from the package 29 with the suction mouth 34.
  • the upper yarn guiding pipe 26 is rotated downward around the axis 35 to guide the upper yarn to the splicer device 14. Finally, splicing of the lower yarn and the upper yarn is performed in the splicer device 14.

  • the unit body member 4 includes the lower part 4b that is immovably fixed to the supporting frame, and the upper part 4a that is movable with respect to the lower part 4b. Furthermore, the pipes 61 are laid from the outside of the unit body member 4 to the upper part 4a via the lower part 4b.
  • the maintainability of the structural components provided in the upper part 4a can be enhanced. Furthermore, because the pipes 61 coming from the outside are introduced from the lower part 4b and the pipes 61 are laid up to the upper part 4a via the lower part 4b, the portion from where the pipes 61 are introduced does not move even when the upper part 4a is moved. Therefore, it is not necessary to take off the pipes 61 in the portion from where the pipes 61 are introduced when moving the upper part 4a. Consequently, the maintainability can be enhanced further.
  • the automatic winder 1 is configured in the following manner. That is, the lower part 4b and the upper part 4a are coupled to each other by the hinge mechanism 10. Furthermore, the pipes 61 are passed near the hinge mechanism 10.
  • the upper part 4a can be moved by using a simple structure consisting of the hinge mechanism 10. Furthermore, by laying the pipes 61 near the hinge mechanism 10, the upper part 4a can be moved without taking off the pipes 61 that are located between the upper part 4a and the lower part 4b.
  • the pipes 61 are passed through the axis of the hinge mechanism 10.
  • the pipes 61 are for supplying the compressed air.
  • the compressed air is also used to generate the swirling airflow to twist the ends of the yarns.
  • the compressed air is also used as the air blast to remove the waste yarn. Therefore, the configuration in which the pipes 61 that carry the compressed air and the control boards 63 are arranged in the separate compartments is particularly suitable.
  • the working fluid is not limited to the compressed air but it can be hydraulic oil.
  • compartments other than the compartments for arranging the boards and the compartments for arranging the pipes can be formed.
  • the textile machine includes a unit body member, a structural component, and a pipe.
  • the structural component is arranged in or near the unit body member.
  • the pipe is made of an elastic material and supplies a compressed air to the structural component to operate the structural component.
  • An inner space of the unit body member is partitioned into at least pipe arrangement compartments by compartment members. Inside the unit body member, the pipe is laid in the pipe arrangement compartments.
  • the pipe can be separated from other component such as a control board, so that undesired situations such as bending of the pipe or rupturing of the pipe due to development of kinks can be prevented from occurring at the time of maintenance of the other component. Because the pipe is arranged separately from the other component, the pipe does not cause hindrance at the time of maintenance of the other component. Furthermore, if by any chance, the pipe is ruptured and the working fluid leaks, adverse effect produced on the other component due to spreading of fly waste by the working fluid is prevented from occurring.
  • the textile machine is configured as follows. That is, in the unit body member, an opening for passing a cable for transmitting electric power and/or electric signals is formed in the compartment member. Moreover, a sealing member is arranged in a gap between the walls of the opening formed in the compartment member and the cable.
  • the textile machine is configured as follows. That is, the textile machine includes a supporting member for supporting the unit body member.
  • the unit body member includes a non-moving member that is immovably fixed to the supporting member, and a moving member that is movable with respect to the non-moving member. Furthermore, the pipe is laid from outside of the unit body member to the moving member via the non-moving member.
  • the maintainability of the structural components provided in the moving member can be enhanced. Furthermore, because the pipe coming from the outside is introduced from the non-moving member and the pipe is laid up to the moving member via the non-moving member, the portion from where the pipe is introduced in the moving member does not move even when the moving member is moved. Therefore, it is not necessary to take off the pipe in the portion from where the pipe is introduced in the moving member when moving the moving member. Consequently, the maintainability can be enhanced further.
  • the textile machine is configured as follows. That is, the non-moving member and the moving member are coupled to each other with a hinge mechanism. Furthermore, the pipe is passed near the hinge mechanism.
  • the moving member can be moved by using a simple structure consisting of the hinge mechanism. Furthermore, by laying the pipe near the hinge mechanism, the moving member can be moved without taking off the pipe that is located between the moving member and the non-moving member.
  • the pipe is passed through an axis of the hinge mechanism.
  • the working fluid is a compressed air.
  • the compressed air is used as the working fluid for various cylinders in the textile machine. Moreover, the compressed air is used to generate a swirling airflow to twist ends of yarns. The compressed air is also used as an air blast to remove the waste yarn. Thus, a configuration in which the pipe that carries the compressed air and the other component such as the control board are arranged in separate compartments is particularly suitable.
