  However, in the conventional fiber supply device 101, when the fiber F is scraped off into the downstream space S, the pin 102 of the rotating body 103 exists in the downstream space S, so that the fiber F is easily entangled with the pin 102. The fibers F may remain on the rotating body 103 side, and the uniformity of the fiber density distribution may be reduced. As a result, frequent maintenance work is required.

  This invention is made | formed in view of the said present condition, and it aims at providing the fiber supply apparatus which can raise the uniformity of the density distribution of a fiber and can supply quantitatively.

In order to solve the above problem, the invention described in claim 1 is a fiber supply device that supplies fibers from the upstream space to the downstream space, and includes a rotating body having a pin that hooks the fibers on the outer peripheral side, The gist of the invention is that when the fiber hooked on the pin in the upstream space by the rotation of the rotating body is supplied to the downstream space, the pin is withdrawn from the downstream space.
According to a second aspect of the present invention, in the first aspect, the rotating body includes a first rotating body and a second rotating body disposed adjacent to each other, and the upstream space and the downstream space are provided. The gist is that each is formed between the first rotating body and the second rotating body.
A third aspect of the present invention includes the stationary cam according to the first or second aspect, wherein the pin is supported by the rotating body so as to be movable in a radial direction. The gist is to have a step portion for moving the pin protruding from the outer periphery of the rotating body to the inside of the rotating body.
A fourth aspect of the present invention includes the endless belt having a hole through which the pin can be put in and out according to the first or second aspect, and a guide portion that is spaced apart from the rotating body. The belt is wound around the outer periphery of the rotating body and the guide portion so that a part of the belt forms the downstream space on the front surface and the back surface forms a wall portion away from the outer periphery of the rotating body. The gist.
A fifth aspect of the present invention includes the partition wall according to the first or second aspect, wherein the partition wall includes a wall portion that forms the downstream space on the front surface and a back surface that is separated from the outer periphery of the rotating body. The gist is that the pin has a notch that can be inserted.

According to the fiber supply device of the present invention, the rotating body having the pin for hooking the fiber on the outer peripheral side is provided, and when the fiber hooked on the pin in the upstream space by the rotation of the rotating body is supplied to the downstream space, the downstream side A pin is withdrawn from space. Thereby, it becomes difficult for the fiber to be entangled with the rotating body such as a pin. Therefore, the uniformity of the density distribution of the fibers can be increased and quantitatively supplied.
The rotating body includes a first rotating body and a second rotating body disposed adjacent to each other, and the upstream space and the downstream space respectively include the first rotating body and the second rotating body.

In addition, the belt includes an endless belt having a hole through which the pin can enter and exit, and a guide portion that is positioned apart from the rotating body, and the belt forms a part of the downstream space on the surface thereof. And when the back surface is wound around the outer periphery of the rotating body and the guide portion so as to form a wall portion away from the outer periphery of the rotating body, the rotating body is caught by the pin in the upstream space by the rotation of the rotating body. When the fiber is supplied to the downstream space, the pin comes out of the hole of the belt at the wall portion so that the pin enters the back surface side of the belt and exits from the downstream space. Thereby, the entanglement of the fiber to the rotating body side such as the pin is suppressed by a relatively simple structure in which the pin is moved in and out of the belt.
In addition, a partition wall having a wall portion that forms the downstream space on the front surface and a back surface that is separated from the outer periphery of the rotating body, and the wall portion has a notch portion through which the pin can be inserted is rotated. When the fiber caught by the pin in the upstream space by the rotation of the body is supplied to the downstream space, the pin inserted into the notch portion of the partition wall enters the back side of the partition wall by pulling out from the notch portion. Exit from the downstream space. Thereby, the entanglement of the fiber to the rotating body side such as the pin is suppressed by a relatively simple structure in which the pin is moved in and out of the partition wall.

<Example 1>
As shown in FIGS. 1 and 2, the fiber supply device 1 according to this embodiment supplies fibers F from the upstream space S1 to the downstream space S2. The fiber supply device 1 includes a cylindrical first rotating body 3a and a second rotating body 3b each having a large number of round bar-like pins 2 for hooking the fibers F on the outer peripheral side.

  The first and second rotating bodies 3a and 3b are disposed adjacent to each other with their rotation axes being substantially parallel. The first and second rotating bodies 3a and 3b are rotatable in synchronization with each other. Specifically, a first gear 4a is attached to one end side of the first rotating body 3a in the axial direction. Moreover, the 2nd gear 4b which meshes with the 1st gear 4a is attached to the one end side of the axial direction of the 2nd rotary body 3b. Each of the first and second gears 4a and 4b is rotatably supported by a support shaft 5 extending in a substantially horizontal direction. One end side of the support shaft 5 is fixed to a standing wall 7 rising from the base 6. The third gear 8 is meshed with the second gear 4b. The rotation shaft of the third gear 8 is rotatably supported by the standing wall 7, and a drive shaft of a drive motor (not shown) is connected to one end side thereof. Therefore, by rotating the first to third gears 4a, 4b, and 8 with the drive motor, the first and second rotating bodies 3a and 3b are rotated in synchronization with the predetermined rotation directions P1 and P2.

  Each of the upstream space S1 and the downstream space S2 is formed between the first and second rotating bodies 3a and 3b. Specifically, the upstream space S1 is formed so as to be surrounded by outer peripheral surfaces that are opposed to each other above the adjacent portions of the first and second rotating bodies 3a and 3b. Further, the downstream space S2 has an outer peripheral surface facing below the adjacent portions of the first and second rotating bodies 3a and 3b, and a substantially L-shaped longitudinal section provided corresponding to each rotating body 3a and 3b. And the scraping member 10. The scraping member 10 has its tip end in contact with the outer peripheral surface of the rotating bodies 3a and 3b (specifically, the outer peripheral surface where the pin 2 enters inside the rotating bodies 3a and 3b as will be described later). Mounted on the base 6.

  A plurality (12 in FIG. 2) of pins 2 are arranged at predetermined angular intervals along the circumferential direction of the rotating bodies 3a and 3b on the outer peripheral side of the first and second rotating bodies 3a and 3b. In addition, the plurality of pins 2 are arranged in a plurality of rows (five rows in FIG. 1) in the axial direction of the rotating bodies 3a and 3b. Each of these pins 2 is supported in a support hole 12 formed in the rotators 3a and 3b so as to be movable in the radial direction of the rotators 3a and 3b. Each pin 2 is urged toward the centripetal side of the rotating bodies 3a and 3b by a spring 13 interposed between the large-diameter portion on the distal end side and the inner peripheral surfaces of the rotating bodies 3a and 3b. . Further, a rolling roller 14 as a cam follower is supported on one end side of each pin 2 so as to freely roll.

  On the center side of the rotating bodies 3a and 3b, a fixed cam 17 having a guide surface 16 on the outer periphery that contacts the rolling roller 14 of each pin 2 is disposed. The fixed cam 17 is attached to a portion of the support shaft 5 that faces the rotating bodies 3a and 3b. Further, the guide surface 16 is formed with a step portion 16a for moving the pin 2 protruding from the outer peripheral surface of the rotating bodies 3a, 3b to the inside of the rotating bodies 3a, 3b at a predetermined timing, as will be described later. (See FIG. 3).

(2) Operation of Fiber Supply Device Next, the operation of the fiber supply device 1 having the above configuration will be described. As shown in FIG. 2, the first and second rotating bodies 3a and 3b are rotated in predetermined rotation directions P1 and P2, so that the fibers F in the upstream space S1 are pinched while being sandwiched between the rotating bodies 3a and 3b. 2 and supplied (discharged) to the downstream space S2. At this time, as shown in FIG. 3, when the rolling roller 14 of the pin 2 gets over the stepped portion 16a of the fixed cam 17, the pin 2 enters the inside of the rotating bodies 3a and 3b and is entangled with the pin 2 F is dropped down. Moreover, when the fiber F remains on the rotating bodies 3a and 3b with the pin 2 inside the rotating bodies 3a and 3b, the scraping member 10 comes into contact with the outer peripheral surfaces of the rotating bodies 3a and 3b. The fiber F is scraped downward.

(3) Effect of Example As described above, according to the fiber supply device 1 of the present example, the rotating body 3a, 3b having the pin 2 for hooking the fiber F on the outer peripheral side is provided, and the upstream side is obtained by the rotation of the rotating body 3a, 3b. When the fiber F caught on the pin 2 in the space S1 is supplied to the downstream space S2, the pin 2 is withdrawn from the downstream space S2. Thereby, it becomes difficult for the fiber F to get entangled with the rotating bodies 3a and 3b such as the pin 2. Therefore, the uniformity of the density distribution of the fibers F can be increased and supplied quantitatively. As a result, it is possible to reduce the frequency of maintenance work and reduce man-hours and costs as compared with the conventional case. In particular, even if the fiber F has a relatively long fiber length (for example, 10 to 30 mm), the entanglement of the pin 2 or the like on the rotating bodies 3a and 3b can be effectively suppressed.

  In this embodiment, the rotating body includes a first rotating body 3a and a second rotating body 3b disposed adjacent to each other, and each of the upstream space S1 and the downstream space S2 is a first rotating body. It is formed between 3a and the 2nd rotary body 3b. Therefore, the fiber F is sandwiched between the first and second rotating bodies 3a and 3b and supplied from the upstream space S1 to the downstream space S2. Thereby, the uniformity of the density distribution of the fiber F is further improved.

  Further, in this embodiment, a fixed cam 17 having a guide surface 16 that comes into contact with the rotating bodies 3a and 3b and a pin 2 supported so as to be movable in the radial direction is provided. The guide surface 16 is an outer periphery of the rotating bodies 3a and 3b. A step portion 16a for moving the pin 2 protruding from the inside of the rotating bodies 3a and 3b is provided. Therefore, when the fiber F hooked on the pin 2 in the upstream space S1 by the rotation of the rotating bodies 3a and 3b is supplied to the downstream space S2, the pin 2 gets over the stepped portion 16a of the fixed cam 17 to thereby rotate the rotating body. It enters inside 3a, 3b and exits from the downstream space S2. Thereby, the entanglement of the fibers F on the rotating bodies 3a and 3b such as the pin 2 is suppressed by a relatively simple structure in which the pins 2 are moved in and out of the rotating bodies 3a and 3b.

  In the present embodiment, the pin 2 of the outer peripheral surfaces of the rotating bodies 3a and 3b is provided with a scraping member 10 that contacts the outer peripheral surface entering the inner side of the rotating bodies 3a and 3b and scrapes the fibers F. Thereby, the entanglement of the fiber F to the rotating bodies 3a and 3b is further reliably suppressed.

  Further, in this embodiment, a spring 13 is provided to urge the pin 2 toward the centripetal direction of the rotating bodies 3a and 3b, and the fixed cam 17 is disposed on the center side of the rotating bodies 3a and 3b. Thereby, the structure which makes the pin 2 move in / out with respect to rotary body 3a, 3b can further be simplified.

<Example 2>
Next, although the fiber supply apparatus which concerns on Example 2 is demonstrated, about the same component as the fiber supply apparatus 1 which concerns on the said Example 1, the same code | symbol is attached | subjected and detailed description is omitted, About both main differences Explain in detail.

  As shown in FIGS. 4 to 6, the fiber supply device 21 according to this embodiment supplies fibers F from the upstream space S1 to the downstream space S2. The fiber supply device 21 includes a cylindrical first rotating body 23a and a second rotating body 23b having a large number of round bar-shaped pins 22 that hook the fibers F on the outer peripheral side. The first and second rotating bodies 23a and 23b are disposed adjacent to each other with their rotation axes being substantially parallel. Further, the first and second rotating bodies 23a and 23b are rotatable in synchronization with each other in substantially the same manner as the fiber supply device 1 of the first embodiment.

  The fiber supply device 21 includes an endless metal belt 26 having a large number of holes 25 through which the pins 22 can enter and exit, and a guide roller 27 that is positioned apart from the rotating bodies 23a and 23b. It is exemplified as a “guidance part”. The belt 26 is wound around the rotating bodies 23a and 23b and the guide roller 27 so that a part of the belt 26 forms a wall portion 28 separated from the outer periphery of the rotating bodies 23a and 23b. The wall portion 28 forms a downstream space S2 on the surface thereof, and the back surface thereof is separated from the outer periphery of the rotating bodies 23a and 23b.

  Each of the upstream space S1 and the downstream space S2 is formed between the first and second rotating bodies 23a and 23b. Specifically, the upstream space S1 is formed by being surrounded by a belt 26 wound around an outer peripheral surface facing the upper side of the adjacent portions of the first and second rotating bodies 23a and 23b. Further, the downstream space S <b> 2 is formed so as to be surrounded by the wall portion 28 of the belt 26.

  A plurality (36 in FIG. 5) of pins 22 are arranged at predetermined angular intervals along the circumferential direction of the rotating bodies 23a, 23b on the outer peripheral side of the first and second rotating bodies 23a, 23b. In addition, the plurality of pins 22 are arranged in a plurality of rows (four rows in FIG. 4) in the axial direction of the rotating bodies 23a and 23b. The belt 26 is formed with holes 25 at positions corresponding to the pins 22.

(2) Operation of Fiber Supply Device Next, the operation of the fiber supply device 21 configured as described above will be described. As shown in FIG. 5, when the first and second rotating bodies 23 a and 23 b are rotated in the predetermined rotation directions P <b> 1 and P <b> 2, the pin 26 is engaged with the hole 25 and the belt 26 is moved around. Then, the fibers F in the upstream space S1 are hooked by the pins 22 while being sandwiched between the rotating bodies 23a and 23b and supplied (discharged) to the downstream space S2 by the rotation of the rotating bodies 23a and 23b. At this time, as shown in FIG. 7, when the pin 22 comes out of the hole 25 at the wall portion 28 of the belt 26, the pin 22 enters the back surface side of the wall portion 28 and the fibers F entangled with the pin 22 downward. Be dropped.

(3) Effects of Example As described above, according to the fiber supply device 21 of the present example, the rotating bodies 23a and 23b having the pins 22 for hooking the fibers F are provided on the outer peripheral side, and the upstream side by the rotation of the rotating bodies 23a and 23b. When the fiber F caught on the pin 22 in the space S1 is supplied to the downstream space S2, the pin 22 is withdrawn from the downstream space S2. Thereby, it becomes difficult for the fiber F to be entangled with the rotating bodies 23a and 23b such as the pin 22. Therefore, the uniformity of the density distribution of the fibers F can be increased and supplied quantitatively. As a result, it is possible to reduce the frequency of maintenance work and reduce man-hours and costs as compared with the conventional case. In particular, even the fiber F having a relatively long fiber length (for example, 10 to 30 mm or the like) can effectively suppress the entanglement of the pin 22 and the like on the rotating bodies 23a and 23b side.

  In this embodiment, the rotating body includes a first rotating body 23a and a second rotating body 23b disposed adjacent to each other, and each of the upstream space S1 and the downstream space S2 is a first rotating body. 23a and the second rotating body 23b. Therefore, the fiber F is sandwiched between the first and second rotating bodies 23a and 23b and supplied from the upstream space S1 to the downstream space S2. Thereby, the uniformity of the density distribution of the fiber F is further improved.

  Further, in this embodiment, the belt 26 is provided with an endless belt 26 having a hole 25 through which the pin 22 can enter and exit, and a guide roller 27 positioned away from the rotating bodies 23a and 23b. The portion is wound around the outer circumferences of the rotating bodies 23a and 23b and the guide roller 27 so that the surface forms the downstream space S2 and the back surface forms the wall portion 28 separated from the outer circumference of the rotating bodies 23a and 23b. Therefore, when the fiber F hooked on the pin 22 in the upstream space S1 by the rotation of the rotating bodies 23a and 23b is supplied to the downstream space S2, the pin 22 comes out of the hole 25 at the wall portion 28, so that the belt 26 It enters the back side and exits from the downstream space S2. Thereby, the entanglement of the fibers to the rotating bodies 23a, 23b such as the pin 22 is suppressed by a relatively simple structure in which the pin 22 is moved in and out of the belt 26.

<Example 3>
Next, although the fiber supply apparatus which concerns on Example 3 is demonstrated, about the same component as the fiber supply apparatus 1 which concerns on the said Example 1, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted, About both main differences Explain in detail.

  As shown in FIGS. 8 to 10, the fiber supply device 31 according to this embodiment supplies fibers F from the upstream space S1 to the downstream space S2. The fiber supply device 31 includes a cylindrical first rotating body 33a and a second rotating body 33b having a large number of round bar-like pins 32 that hook the fibers F on the outer peripheral side. The first and second rotating bodies 33a and 33b have a rotation axis substantially parallel and are disposed adjacent to each other. The first and second rotating bodies 33a and 33b can be rotated in synchronization with each other in substantially the same manner as the fiber supply device 1 of the first embodiment.

  The fiber supply device 31 includes a partition wall 36 having a wall portion 37 whose upper end side approaches or contacts the outer peripheral surfaces of the rotating bodies 33a and 33b. This partition wall 36 is attached on the base 6 so that the downstream space S2 is formed on the surface of the wall portion 37 and the back surface of the wall portion 37 is separated from the outer periphery of the rotating bodies 33a and 33b. The wall portion 37 is formed with a plurality of (four in FIG. 10) notches 35 that are notched from the end side and into which the pins 32 can be inserted.

  Each of the upstream space S1 and the downstream space S2 is formed between the first and second rotating bodies 33a and 33b. Specifically, the upstream space S1 is formed to be surrounded by an outer peripheral surface that is opposed to the upper side of the adjacent portions of the first and second rotating bodies 33a and 33b. Further, the downstream space S <b> 2 is mainly formed by being surrounded by the partition wall 36.

  A plurality (36 in FIG. 9) of pins 32 are arranged at predetermined angular intervals along the circumferential direction of the rotating bodies 33a and 33b on the outer peripheral side of the first and second rotating bodies 33a and 33b. In addition, the plurality of pins 32 are arranged in a plurality of rows (four rows in FIG. 8) in the axial direction of the rotating bodies 33a and 33b.

(2) Operation of Fiber Supply Device Next, the operation of the fiber supply device 31 having the above configuration will be described. As shown in FIG. 9, when the first and second rotating bodies 33a, 33b are rotated in predetermined rotation directions P1, P2, the fibers F in the upstream space S1 are rotated by the rotation of the rotating bodies 33a, 33b. , 33b, being hooked on the pin 32 and supplied (discharged) to the downstream space S2. At this time, as shown in FIG. 11, the pin 32 is once inserted into the notch 35 of the partition wall 36 and then pulled out, so that the pin 32 enters the back side of the partition wall 36 and is entangled with the pin 32. Is dropped down.

(3) Effect of Example As described above, according to the fiber supply device 31 of the present example, the rotating body 33a, 33b having the pin 32 for hooking the fiber F on the outer peripheral side is provided, and the upstream side is obtained by the rotation of the rotating body 33a, 33b. When the fiber F caught on the pin 32 in the space S1 is supplied to the downstream space S2, the pin 32 is withdrawn from the downstream space S2. Thereby, it becomes difficult for the fibers to be entangled with the rotating bodies 33a and 33b such as the pin 32. Therefore, the uniformity of the density distribution of the fibers F can be increased and supplied quantitatively. As a result, it is possible to reduce the frequency of maintenance work and reduce man-hours and costs as compared with the conventional case. In particular, even if the fiber F has a relatively long fiber length (for example, 10 to 30 mm), the entanglement of the pin 32 or the like on the rotating bodies 33a and 33b can be effectively suppressed.

  In this embodiment, the rotating body includes a first rotating body 33a and a second rotating body 33b disposed adjacent to each other, and each of the upstream space S1 and the downstream space S2 is a first rotating body. It is formed between 33a and the 2nd rotary body 33b. Therefore, the fiber F is sandwiched between the first and second rotating bodies 33a and 33b and supplied from the upstream space S1 to the downstream space S2. Thereby, the uniformity of the density distribution of the fiber F is further improved.

  Further, in the present embodiment, the partition wall 36 having the wall portion 37 that forms the upstream space S2 on the front surface and the back surface is separated from the outer periphery of the rotating bodies 33a and 33b, and the pin 32 can be inserted into the wall portion 37. A notch 35 is provided. Therefore, when the fiber F hooked by the pin 32 in the upstream space S1 by the rotation of the rotating bodies 33a and 33b is supplied to the downstream space S2, the pin 32 inserted through the notch 35 of the partition wall 36 is notched. By exiting from 35, it enters the back side of the partition wall 36 and exits from the downstream space S2. Thereby, the entanglement of the fiber F to the rotating bodies 33a and 33b such as the pin 32 is suppressed by a relatively simple structure in which the pin 32 is moved in and out of the partition wall 36.

  In the present invention, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention depending on the purpose and application. That is, in the above-described Examples 1 to 3, the fiber supply devices 1, 21, and 31 including the first and second rotating bodies 3a, 3b, 23a, 23b, 33a, and 33b are exemplified. As shown in FIG. 12, it is good also as a fiber supply apparatus 1 'provided only with the single rotary body 3. As shown in FIG. In this case, for example, each of the upstream space S1 and the downstream space S2 is formed by being surrounded by the rotating body 3 and the wall portion 39 facing the rotating body 3.

  In the first to third embodiments, the rotating bodies 3a, 3b, 23a, 23b, 33a, and 33b that can rotate around the horizontal axis are exemplified. However, the present invention is not limited to this. Alternatively, the rotating body may be a rotating body or a rotating body that is rotatable about the vertical axis. Furthermore, in the said Examples 1-3, although the round bar-shaped pins 2, 22, and 32 were illustrated, it is not limited to this, For example, it is good also as a square bar-shaped pin.

  Further, in the first embodiment, the tip surface of the pin 2 and the outer peripheral surface of the rotating bodies 3a and 3b are made to substantially coincide with each other in the maximum movement state of the pin 2 to the inside of the rotating bodies 3a and 3b (see FIG. 3). ) Is not limited to this. For example, in the maximum movement state of the pin 2 to the inside of the rotating bodies 3a and 3b, the tip end surface of the pin 2 slightly protrudes from the outer peripheral surface of the rotating bodies 3a and 3b. 2 tip surfaces may be slightly immersed inward from the outer peripheral surfaces of the rotating bodies 3a and 3b.

  Moreover, in the said Example 1, although the pin 2 was urged | biased with the spring 13, it is not limited to this, For example, you may bias a pin with elastic materials, such as rubber | gum, an air cushion mechanism, etc. Further, in the first embodiment, the rolling roller 14 is exemplified as the cam follower. However, the present invention is not limited to this, and for example, the one end side of the pin 2 is made to directly follow the guide surface 16 of the fixed cam 17. Also good.

  In the second embodiment, the guide roller 27 is illustrated as a guide part that separates a part of the belt 26 from the outer periphery of the rotating bodies 23a and 23b. However, the guide roller 27 is not limited to this example. A typical support shaft may be employed. Moreover, the guide part of the belt 26 may be single, and may be two or more.

  Furthermore, the fiber supply apparatuses 1, 21, and 31 of Examples 1 to 3 can be used, for example, for supplying fibers to a molding machine or for adding a nonwoven fabric manufacturing material.
