  • the present invention relates to a cleaning device for removing and cleaning fiber or the like adhered to a draft roller which drafts a fiber bundle.
  • a textile machine such as a spinning machine includes a cleaning device for cleaning an outer peripheral surface of a draft roller by making a pad body to come into contact with the outer peripheral surface of the draft roller.
  • a cleaning device for cleaning an outer peripheral surface of a draft roller by making a pad body to come into contact with the outer peripheral surface of the draft roller.
  • Japanese Unexamined Patent Application Publication No. 2009-68126 discloses such kind of cleaning device.
  • the cleaning device includes a pad body arranged capable of being made into contact with an outer peripheral surface of a draft roller, and a suction collector arranged so as to face to the outer peripheral surface of the draft roller.
  • a width of the pad body is formed so as to be at least one-half of an average fiber length of a fiber to be drafted, and also to be shorter than or equal to a width of a suction opening of the suction collector.
  • the cleaning device includes a pad supporting member, which is formed of an elastic member and supports the pad body.
  • the pad supporting member is integrally formed from a pad supporting section on which the pad body is mounted, a fixed section fixed to a fixed member, and a driven section driven and pressed in order to move the pad body away from the draft roller.
  • the pad body is pressed against the outer peripheral surface of the draft roller by restoring force of the pad supporting member, which is being elastically-deformed.
  • the present invention has been made in view of the above-described problem, and it is an object of the present invention to provide a cleaning device for a draft roller in which a pad body is provided to be made into contact with or to be moved away from the draft roller and pressing force of the pad body against the draft roller is maintained constant.
  • the cleaning device for the draft roller is according to claim 1. .
  • the torsion spring is mounted on the fixed member and applies force to swing the pad supporting member in a direction in which the pad body is made into contact with an outer peripheral surface of the draft roller.
  • the lever member can apply force to swing the pad supporting member in a direction in which the pad body is moved away from the outer peripheral surface of the draft roller, by moving away from the draft roller.
  • the pressing force of the pad body against the draft roller can be kept constant for a long period of time. Therefore, since the force for pressing the pad body against the draft roller is stabilized, resonance of the pad body can be prevented, and feeding of the yarn by the draft roller can be stabilized. As a result, generation of variability in yarn property of a spun yarn to be produced can be avoided.
  • a simple mechanism can be accomplished in which the pad body can be moved away from the draft roller accompanying movement of the lever member away from the draft roller.
  • the cleaning device for the draft roller includes a transmission member and a second torsion spring.
  • the transmission member includes a contact section which can be made into contact with the pad supporting member, and a driven section which can be made into contact with the lever member.
  • the transmission member is arranged capable of swinging with respect to the fixed member.
  • One end of the second torsion spring is connected to the transmission member.
  • Another end of the second torsion spring is connected to the pad supporting member.
  • the second torsion spring applies spring force such that the contact section is pressed against the pad supporting member.
  • the lever member is made into contact with the driven section by moving away from the draft roller, and swings the transmission member. Accompanying the swinging movement of the transmission member, the pad supporting member swings and the pad body moves away from the outer peripheral surface of the draft roller.
  • the fixed member in the cleaning device for the draft roller has a plurality of positions where the torsion spring can be mounted. Accordingly, pressing force of the pad body applied to the draft roller can be adjusted just by changing the position where the torsion spring is mounted.
  • the cleaning device for the draft roller includes a regulating member to regulate swinging movement of the pad supporting member in a direction in which the pad body moves away from the draft roller. Accordingly, even when the lever member moves drastically, the pad supporting member can be prevented from swinging excessively. In addition, when mounting the pad body on the pad supporting body, since a position of the pad supporting member can be fixed by making the pad supporting member to contact with the regulating member, the mounting work can be easily carried out.

  • An apron belt is wound around the apron belt roller.
  • the apron belt shifting member is traversed to traverse the apron belt.
  • the apron belt shifting member is mounted on the mounting member.
  • the fixed member supporting section is independent from the mounting member and used to mount the fixed member.
  • apron belt shifting member is mounted on the mounting member which is a different member from the fixing member supporting section on which the fixed member is mounted, influence on the pad body resulting from vibration or the like, which is caused by traversing movement of the apron belt shifting member, can be suppressed effectively.

  • the spinning machine 1 includes the middle bottom roller 26, the apron fork 99, the shaft 68, and the fixed frame 67.
  • the bottom apron belt 27 is wound around the middle bottom roller 26.
  • the apron fork 99 is traversed to traverse the bottom apron belt 27.
  • the apron fork 99 is mounted on the shaft 68.
  • the fixed frame 67 is independent from the shaft 68 and used to mount the fixed member 90.
  • the urging force of the first torsion spring 94 is applied to the pad supporting lever 70 via the transmission lever 71.
  • This structure can be modified according to situations.
  • a cleaning device can be formed such that a torsion spring applies spring force to a pad supporting lever directly. Since an urging mechanism to press a pad body against a front bottom roller is a torsion spring which is unlikely to be plastically-deformed, pressing force of the pad body against the front bottom roller can also be kept within a certain range for a long period of time by such a structure.
  • the structure can be simplified. However, from a viewpoint of preventing damage of the pad supporting lever 70, the structure of the above described embodiment including the transmission lever 71 and the second torsion spring 95 is preferable.
  • material of the pad body 62 in place of soft resin, for example, rubber or non-woven fabric can be adopted.
  • the cleaning device 61 can be adopted as a structure for cleaning not only the front bottom roller 28 but also for cleaning other draft rollers.
  • a suction collector can be provided for sucking and removing fiber, fiber waste, or the like adhered on the pad body 62.
  • such suction collector can be mounted on the supporting arm 29 such that a suction opening of the suction collector faces an outer peripheral surface of the front bottom roller 28.
  • fiber accumulation on the pad body 62 can be reduced by sucking and removing the fiber, and burden on maintenance can be reduced.
  • the draft device 7 according to the above-described embodiment can be applied not only to the spinning machine 1 but also to a textile machine such as a roving frame, and a drawing frame.
