  As shown in FIG. 5, in the housing 71, four rectangular plate-shaped partition members (chamber forming portions) 87 are attached to the support shaft 82 at intervals of 90 °. The four partition members 87 are arranged in the rotation direction and form four filter chambers 89 in which a filter 88 is provided in the housing 71. The filter 88 is disposed on the end surface on the downstream side of the filter chamber 89 in the passage direction of the suction air flow (that is, the end surface on the second main wall 71b side of the housing 71).

The first sealing member 91, the second sealing member 92, and the third sealing member 93 can maintain airtightness with the inner surface of the housing 71 and can reduce the frictional resistance with the inner surface of the housing 71. (For example, a fluororesin).

  Operation | movement of the fiber discharge apparatus 70 comprised as mentioned above is demonstrated. As indicated by arrows in FIG. 3, the suction air flow generated by the blower 42 sequentially passes through the suction duct 41, the air flow passage region R1 of the fiber discharge device 70, the discharge duct 43, and the impeller case 42a. It is discharged outside. At this time, in the fiber discharging device 70, as shown in FIG. 5, one filter chamber 89 is positioned in the air flow passage region R1. Therefore, fibers such as fluff are removed from the suction air flow by the filter 88 provided in the filter chamber 89.

  When a predetermined time elapses after one filter chamber 89 is positioned in the air flow passage region R1, the support shaft 82 is rotated 90 ° by the motor 86, and the four partition members 87 are integrally 90 °. Rotated. Thereby, the filter chamber 89 located in the air flow passage region R1 is positioned in the first standby region R2a. Since the suction air flow does not act on the filter chamber 89 located in the first standby region R <b> 2 a, the fibers attached to the filter 88 are dropped and stored in the filter chamber 89.

  When a predetermined time elapses after one filter chamber 89 is positioned in the first standby region R2a, the support shaft 82 is rotated 90 ° by the motor 86, and the four partition members 87 are integrally 90 °. Rotated. As a result, the filter chamber 89 located in the first standby region R2a is positioned in the open region R3 and is released to atmospheric pressure. In the housing 71, an opening 81 that opens the filter chamber 89 located in the open region R <b> 3 to the outside of the housing 71 is formed downward in the vertical direction. Therefore, the fibers accumulated in the filter chamber 89 are opened in the opening 81. And is discharged to the outside of the housing 71. The fibers discharged to the outside of the housing 71 are transported to a fiber recovery box or a duct provided below the installation surface by a transport device such as a belt conveyor. Or the fiber discharged | emitted outside the housing 71 is directly dropped from the filter chamber 89 located in the open area | region R3 by the duct provided under the installation surface.

  When a predetermined time elapses after one filter chamber 89 is positioned in the open region R3, the support shaft 82 is rotated 90 ° by the motor 86, and the four partition members 87 are integrally rotated 90 °. It is done. As a result, the filter chamber 89 located in the open area R3 is positioned in the second standby area R2b. When a predetermined time elapses after one filter chamber 89 is positioned in the second standby region R2b, the support shaft 82 is rotated 90 ° by the motor 86, and the four partition members 87 are integrally 90 °. Rotated. Thereby, the filter chamber 89 located in the second standby region R2b is again located in the air flow passage region R1.

  In the fiber discharging device 70, the above operation is repeated, whereby the removed fibers are discharged while the removal of the fibers from the suction air flow is continued. In the fiber discharge device 70, when the four filter chambers 89 are rotated with respect to the air flow passage region R1, the first standby region R2a, the open region R3, and the second standby region R2b, one filter chamber 89 flows through the air. Since a state that simultaneously straddles the excess region R1 and the open region R3 cannot occur, occurrence of pressure loss in the air flow passage region R1 is suppressed. Each time a predetermined time elapses, instead of the support shaft 82 being rotated by the motor 86, the amount of fibers adhering to the filter 88 reaches a predetermined amount in the filter chamber 89 located in the air flow passage region R1. When this is detected by a sensor, the support shaft 82 may be rotated by the motor 86.

  As described above, in the fiber discharge device 70, the four filter chambers 89 are sequentially positioned in the air flow passage region R1, the first standby region R2a, the open region R3, and the second standby region R2b, respectively. In the filter chamber 89 located in the flow passage region R1, the fibers can be removed from the suction air flow containing fibers such as fluff. In the filter chamber 89 located in the open region R3, the fibers adhere to the filter 88. The fiber can be removed and discharged to the outside. When the four filter chambers 89 are rotated relative to the air flow passage region R1, the first standby region R2a, the open region R3, and the second standby region R2b with the rotation axis L as the center line, Since the excess region R1 and the open region R3 are separated via the first standby region R2a and the second standby region R2b, it is possible to suppress the occurrence of pressure loss in the air flow passage region R1. Therefore, according to the fiber discharge device 70, the pressure loss generated in the suction air flow can be suppressed, and the installation area can be saved. Moreover, since it is a simple structure, the cost reduction of the fiber discharge apparatus 70 can also be achieved.

  In the fiber discharging device 70, the filter 88 is disposed on the end face on the downstream side of the filter chamber 89 in the direction of passage of the suction air flow. Thereby, the fibers removed from the suction air flow can be stored in the filter chamber 89, and when the filter chamber 89 is located in the open region R3, the fibers stored in the filter chamber 89 are surely discharged to the outside. be able to. Further, since the holding plate 75 in which the plurality of holes 75a are formed is provided in the air flow outlet 74 so as to be flush with the second main wall 71b, the filter chamber 89 located in the air flow passage region R1. It is possible to suppress the deflection of the filter 88 in FIG.

  In the fiber discharging device 70, an opening 81 that opens the filter chamber 89 located in the open region R3 to the outside of the housing 71 is formed in the housing 71 downward in the vertical direction. Thereby, when the filter chamber 89 is positioned in the open region R3, the fibers stored in the filter chamber 89 can be easily and reliably discharged to the outside by dropping through the opening 81.

  In the fiber discharging device 70, a motor 86 that rotates the support shaft 82 is provided. Accordingly, the four filter chambers 89 can be sequentially positioned in the air flow passage region R1, the first standby region R2a, the open region R3, and the second standby region R2b with a simple configuration.

  In the fiber discharging device 70, sealing members 91, 92, and 93 that are in contact with the inner surface of the housing 71 are provided on the partition member 87. Thereby, it is possible to suppress external air from flowing into the air flow passage region R1 from the open region R3 via the first standby region R2a and the second standby region R2b, and pressure loss occurs in the air flow passage region R1. Generation | occurrence | production can be suppressed more reliably. Note that, between the inner surface of the first main wall 71a of the housing 71 and the first sealing member 91 and between the inner surface of the second main wall 71b of the housing 71 and the second sealing member 92, respectively, Even if the fibers are caught, when the first sealing member 91 and the second sealing member 92 reach the first cutout 78 and the second cutout 79, respectively, the pinching of the fibers is eliminated and the fibers fall. It will be. Similarly, even if fibers such as fluff are sandwiched between the inner surface of the side wall 71 c of the housing 71 and the third sealing member 93, the fibers are sandwiched when the third sealing member 93 reaches the opening 81. Will be eliminated and the fiber will fall.

  In the fiber discharge device 70, the blower 42 is connected to the downstream side of the air flow passage region R1 in the passage direction of the suction air flow. Thus, a suction air flow that passes through the air flow passage region R1 can be reliably generated, and fibers can be reliably removed from the suction air flow in the filter chamber 89 located in the air flow passage region R1.

  In the fiber discharging device 70, the housing 71 has a cylindrical shape with the rotation axis L as the center line. Thereby, the fiber discharge device 70 can be made compact, and further space saving of the installation area can be achieved.
