Positions of the back roller housing 61, the third roller housing 62, and the middle roller housing 63 are respectively adjustable along the running path R. As a result, a distance between the front bottom roller 17a and the middle bottom roller 16a, a distance between the middle bottom roller 16a and the third bottom roller 15a, and a distance between the third bottom roller 15a and the back bottom roller 14a can be respectively adjusted.

- the main body 73a holds the contacting member 73b.
- the contacting member 73b has at least one convex part that touches the third bottom roller 15a.
- the main body 73a and the contacting member 73b are made from resin, for example.
- the magnet 73c is arranged in the main body 73a.
- the cleaning device 73 is pressed against an outer circumferential surface of the third bottom roller 15a and it is forced to rotate following the rotation of the third bottom roller 15a.
- this rotation of the cleaning device 73 is prevented by a not-shown stopper. Accordingly, the contacting member 73b rubs the outer circumferential surface of the rotating third bottom roller 15a whereby fibers adhering to the peripheral surface of the third bottom roller 15a are removed.
- a cleaning device having the same configuration as the cleaning device 73 is also arranged with respect to the back bottom roller 14a.
- a fiber collecting device 80 (not shown in FIGS. 1 and 2 ) is arranged on one side of the bottom rollers 14a, 15a, and 16a with the top rollers 14b, 15b, and 16b being arranged on the other side.

- the drafting device 6 is arranged, in a state in which the back roller pair 14 is positioned above and the front roller pair 17 is positioned below in the vertical direction, such that each bottom roller 14a, 15a, 16a, and 17a is arranged in an inclined manner whereby it is positioned at a lower level than each top roller 14b, 15b, 16b, and 17b respectively.
- a suction passage 83 is arranged within the main body 81.
- the suction passage 83 extends parallel to the running path R. In other words, the direction in which suction is performed by the suction passage 83 is the same as the longitudinal direction of the fiber collecting device 80 and also extends along the drafting direction.
- the suction-port adjusting member 82 includes a suction port 84 that is connected to a connection opening 83a of the suction passage 83. Only one suction port 84 is arranged for each drafting device 6, and the suction port 84 faces the middle bottom roller 16a of the middle roller pair 16, which is the second roller pair from the downstream side, and the third bottom roller 15a of the third roller pair 15, which is the third roller pair from the downstream side.
- a suction-port inclined surface 85 that extends from the suction port 84 to the connection opening 83a of the suction passage 83 is arranged between the suction port 84 and the suction passage 83.
- the suction-port inclined surface 85 makes an acute angle with respect to an opening plane 84a (an imaginary plane formed by the open area of the suction port 84) of the suction port 84 and extends from a downstream end portion 84b of the suction port 84 to a bottom portion (a portion that opposes the opening plane 84a in the connection opening 83a) of the connection opening 83a.
- a suction pipe 93 is connected to a connection opening 83b that is located on the opposite side of the suction port 84 in the suction passage 83.
- the suction pipe 93 is connected to a not-shown blower that generates a suction air current.
- the fiber waste generated in the drafting device 6 is sucked from the suction port 84, passed through the suction passage 83 and the suction pipe 93, and collected in a not-shown fiber discharging device arranged near the blower.
- a cross-sectional surface area of the suction passage 83 that extends from the connection opening 83a to the connection opening 83b can be the same (constant) everywhere, can gradually increase, or can gradually decrease. In a configuration where the cross-sectional surface area gradually decreases, because a high-speed current is generated near the connection opening 83a, accumulation of the fiber waste may be suppressed.
- the main body 81 is formed integrally with resin, for example.
- the suction-port adjusting member 82 is also formed integrally with resin, for example.
- the suction-port adjusting member 82 is attached to the main body 81 with a bolt 86, and the suction-port adjusting member 82 can be attached to and/or detached from the main body 81 by using a bolt attaching/detaching mechanism.
- Plural types of the suction-port adjusting members 82 are prepared in advance and an appropriate one of the suction-port adjusting members 82 is used depending on the type of the fibers of the sliver S. Accordingly, the suction-port adjusting member 82 adjusts at least one of a shape and a position of the suction port 84 (i.e., the shape and/or the position of the suction port 84).
- a positioning member 87 is arranged in the main body 81.
- the positioning member 87 includes an end surface 87a positioned on both sides of the suction-port adjusting member 82.
- the positioning member 87 performs positioning of the main body 81 with respect to the third bottom roller 15a by causing the end surface 87a to make contact with a positioning plate 91 that is fixed to the third roller housing 62.
- the main body 81 in a state in which it has been positioned by the positioning member 87, is fixed with a bolt 88 to a supporting plate 92 that has been fixed to the back roller housing 61.
- a distance between adjacent roller pairs 17 and 16, a distance between adjacent roller pairs 16 and 15, and a distance between adjacent roller pairs 15 and 14 are simply called “roller pair distance”.
- a suction-port adjusting member 82 appropriate for the chemical fibers i.e., for the sliver S that mainly contains chemical fibers
- the main body 81 is attached to the main body 81 and at least one of the shape and the position of the suction port 84 is in a first state specific for the chemical fibers.
- a suction-port adjusting member 82 appropriate for the cotton fibers is attached to the main body 81 and at least one of the shape and the position of the suction port 84 is in a second state specific for the cotton fibers.
- the "sliver S that mainly contains cotton fibers” is a sliver S that contains 50% or more of 100% cotton.
- the "sliver S that mainly contains chemical fibers” is a sliver S that contains less than 50% of 100% cotton and an average fiber length of the chemical fibers is from 32 millimeters (mm) to 51 mm.
- the suction-port inclined surface 85 is constituted by the suction-port adjusting member 82 in the first state and constituted by the main body 81 in the second state.
- the second distance is shorter than the first distance.
- the reason is because the cotton fibers contain more short fibers than the chemical fibers.
- the downstream end portion 84b of the suction port 84 is positioned relatively on the downstream side (near the front roller pair) in the second state than in the first state.
- an end inclined surface 94 that gradually inclines downward going toward an end portion thereof is arranged at the end portion (downstream end portion in the drafting direction) of the suction-port adjusting member 82.
- the end inclined surface 94 is formed on both lateral sides around the suction port 84.
- the both lateral sides here mean one side and the other side in an axial direction of the draft roller.
- the end inclined surface 94 is formed on an upper surface (surface facing the bottom roller) of the suction-port adjusting member 82.
- the shape (inclination angle and/or length of an inclined part) of the end inclined surface 94 is not limited to that shown in FIG. 7 .
- the inclined part can be longer (length along the drafting direction) than that shown in FIG. 7 . Because the end portion of the suction-port adjusting member 82 extends to a position below the middle bottom roller 16a (to a position facing the middle bottom roller 16a) and because the suction-port adjusting member 82 includes the end inclined surface 94, a space that is fairly large can be secured between the middle bottom roller 16a (apron belt 18a) and the suction port 84. As a result, fiber waste can be prevented from accumulating in this space.
- the fiber collecting device 80 includes the main body 81 that has the suction passage 83, and the suction-port adjusting member 82 that adjusts at least one of the shape and the position of the suction port 84 connected to the suction passage 83. Accordingly, in the fiber collecting device 80, at least one of the shape and the position of the suction port 84 can be appropriately adjusted depending on the type of the fibers. Therefore, in the fiber collecting device 80, even if the type of the fibers is changed, the fiber waste can be collected efficiently.
- the suction-port adjusting member 82 is attachable to and/or detachable from the main body 81.
- at least one of the shape and the position of the suction port 84 can be adjusted with a simple structure.
- the structure is simple, the fiber waste does not accumulate easily as compared to a structure in which, for example, the suction port is arranged in the main body and a separate member such as a sliding member or a rotating member is arranged so as to function as the suction-port adjusting member.
- the fiber collecting device 80 further includes the positioning member 87 that performs positioning of the third bottom roller 15a of the third roller pair 15, which is the third roller pair from the downstream side, with respect to the main body 81.
- the suction-port inclined surface 85 that extends from the suction port 84 to the connection opening 83a of the suction passage 83 is arranged between the suction port 84 and the suction passage 83.
- the fiber collecting device 80 can be attached to and/or detached from the drafting device 6 by attaching and/or detaching the bolt 88. Accordingly, maintenance can be performed easily.
- the roller pair distance when the roller pair distance is equal to the first distance suitable for drafting the sliver S that mainly contains chemical fibers, at least one of the shape and the position of the suction port 84 is in the first state specific for the chemical fibers.
- the roller pair distance is equal to the second distance suitable for drafting the sliver S that mainly contains cotton fibers, at least one of the shape and the position of the suction port 84 is in the second state specific for the cotton fibers.
- the downstream end portion 84b of the suction port 84 is positioned relatively on the downstream side in the second state than in the first state.
- the fiber waste is easily generated near the third bottom roller 15a due to curling-up of fibers and the like.
- the drafting device 6 only one suction port 84 of the fiber collecting device 80 is caused to face the third bottom roller 15a. Also, the fiber waste is easily generated even near the middle bottom roller 16a when drafting the sliver S that mainly contains cotton fibers.
- the downstream end portion 84b of the suction port 84 is positioned relatively on the downstream side (i.e., the downstream end portion 84b of the suction port 84 is located near the middle bottom roller 16a). Therefore, in the drafting device 6, even if the type of the fibers is changed, the fiber waste can be collected efficiently.
- the position adjustment of the downstream end portion 84b of the suction port 84 toward the downstream side is effective not only when drafting a sliver S that contains 100% cotton, but also, for example, when drafting a sliver S made of blended material containing carded cotton, having a high short-fiber content, and chemical fiber material.
- the position adjustment of the downstream end portion 84b of the suction port 84 toward the downstream side is effective when drafting a sliver S that is made of material in which the fibers can get easily accumulated below the middle bottom roller 16a.
- the collection rate of the fiber waste can be improved by adjusting at least one of the shape and the position of the suction port 84 based on environment and/or conditions.
- Temperature and/or humidity in the room in which the spinning machine 1 is operating can be taken as an example of the environment.
- the ease with which fibers are wound on each bottom roller 14a, 15a, 16a, and 17a varies depending on the temperature and/or the humidity in the room in which the spinning machine 1 is operating. For example, when the humidity is high, the fibers easily adhere to the apron belt 18a.
- a drafting rate force with which the fibers are pulled
- the fibers are easily wound on the bottom rollers 14a, 15a, 16a, and 17a.
- the cleaning device 73 is arranged with respect to each of the third bottom roller 15a and the back bottom roller 14a. With this arrangement, the fibers can be removed from the third bottom roller 15a and the back bottom roller 14a in which the fibers easily curl-up.
- the drafting device 6 is arranged, in a state in which the back roller pair 14 is positioned above and the front roller pair 17 is positioned below in the vertical direction, such that each bottom roller 14a, 15a, 16a, and 17a is arranged in an inclined manner whereby it is positioned at a lower level than each top roller 14b, 15b, 16b, and 17b respectively. Therefore, the fibers that were removed by the cleaning devices 73 fall with their own weight on the suction-port inclined surface 85 as the fiber waste and are sucked from the suction port 84.
- the fiber collecting device 80 can include a flow-rate adjusting section 89 that adjusts a suction air flow rate of the suction port 84.
