According to the non-woven fabric manufacturing apparatus, two non-woven fabrics can be manufactured by the two front and back surfaces of the plate-shaped member, but the non-woven fabric manufactured by stopping the apparatus every time the two non-woven fabrics are manufactured is a plate-shaped member. For example, in order to manufacture six non-woven fabrics, the non-woven fabrics must be removed from the plate-like member three times, and the operation is complicated.
In view of such circumstances, the present invention provides a non-woven fabric manufacturing apparatus capable of manufacturing six non-woven fabrics at a time by using a cubic member instead of a plate-like member.

That is, the invention of claim 1 is a rotary shaft that is rotatably supported, an inclined shaft that is obliquely disposed on the rotational shaft at a predetermined angle with respect to the axis, and six rotationally provided on the inclined shaft. A cubic member having a surface, wherein the first surface and the sixth surface are opposed to each other, the second surface and the fifth surface are opposed to each other, and the third surface and the fourth surface are The cube members are opposed to each other, and the cube member is rotated with respect to the tilt axis, and a first posture position where the rotation axis is perpendicular to the first surface and the sixth surface, and a second surface The second posture position perpendicular to the fifth surface and the third posture position perpendicular to the third surface and the fourth surface are fixed at the respective positions.
The second surface, the third surface, the fourth surface, and the second surface in a state where the cube member is positioned at the first posture position while switching the position of the cube member to each of the first posture position, the second posture position, and the third posture position. The yarn is wound up over five surfaces, and the yarn is wound up over the first surface, the third surface, the fourth surface, and the sixth surface in a state where the yarn is positioned in the second posture position, and is further moved to the third posture position. The yarn is wound around the first surface, the second surface, the fifth surface, and the sixth surface in the positioned state.

  According to the above configuration, since the nonwoven fabric can be manufactured by winding the yarn around all six surfaces of the cubic member, it is possible to manufacture six nonwoven fabrics at a time, and thus each time two nonwoven fabrics are manufactured. Compared with the conventional apparatus which needs to stop an apparatus, a nonwoven fabric can be manufactured efficiently.

Hereinafter, the present invention will be described with reference to the illustrated embodiment. In FIG. 1, the nonwoven fabric manufacturing apparatus 1 according to the present invention includes two support frames 3 and 4 erected on a base 2 at a predetermined interval. Rotating shafts 5 and 6 are rotatably supported on the respective support frames.
The rotary shafts 5 and 6 are arranged on the same straight line, and extend radially outward at an angle of 90 degrees from the axis of each rotary shaft and in opposite directions from each other at the opposite ends of the rotary shafts. A first holding member 7 and a second holding member 8 are provided. And between the front-end | tip parts of both the holding members 7 and 8, the inclination axis | shaft 9 arrange | positioned diagonally with a required angle with respect to the axis line of the said rotating shafts 5 and 6 is provided.

The rectangular cubic member 21 for winding the yarn is configured by combining a total of 12 rod-shaped bodies having a square cross section constituting each side of the cube in a cubic shape, and the inclined shaft 9 is formed of the cubic member 21. The cube member 21 is passed through a diagonal line passing through the center O. The length of the holding member is adjusted so that the center O of the cubic member 21 is on the axis of the rotation shafts 5 and 6.
The cube member 21 is rotatable about the tilt axis 9, and as shown in FIG. 1, the cube member 21 is moved to the first posture position, the second posture position, and the second position by the locking means 22 provided on the tilt shaft 9. The posture can be fixed to the inclined shaft 9 while changing the posture to any one of the three posture positions.

That is, the cube member 21 has the first surface I and the sixth surface VI facing each other, the second surface II and the fifth surface V facing each other, and the third surface III and the fourth surface IV. The first surface I and the sixth surface VI are perpendicular to the axes of the rotary shafts 5 and 6 in the first posture position shown in FIG.
Therefore, in this state, the other second surface II, third surface III, fourth surface IV and fifth surface V are all parallel to the axis of the rotation shafts 5 and 6, so that the rotation shaft 5, If the cube member 21 is rotated integrally therewith via 6, the yarn can be wound around the second surface II, the third surface III, the fourth surface IV and the fifth surface V.

Moreover, in the 2nd attitude | position position which rotated the cube member 21 120 degree | times to the arrow direction of a figure from the 1st attitude | position position shown in FIG. 1, as shown in FIG. 2, the 2nd surface II and the 5th surface V rotate. It is perpendicular to the axes of the axes 5 and 6.
Accordingly, in this state, the other first surface I, third surface III, fourth surface IV, and sixth surface VI are all parallel to the axis of the rotation shafts 5 and 6, so that the rotation shaft 5, If the cube member 21 is rotated integrally therewith via 6, the yarn can be wound around the first surface I, the third surface III, the fourth surface IV and the sixth surface VI.

Further, in the third posture position where the cube member 21 is rotated 120 degrees in the direction of the arrow in the drawing from the second posture position shown in FIG. 2, the third surface III and the fourth surface IV rotate as shown in FIG. It is perpendicular to the axes of the axes 5 and 6.
Accordingly, in this state, the other first surface I, second surface II, fifth surface V and sixth surface VI are all parallel to the axis of the rotation shafts 5 and 6, so that the rotation shaft 5, If the cube member 21 is rotated integrally therewith via 6, the yarn can be wound around the first surface I, the second surface II, the fifth surface V and the sixth surface VI.

The axes of the rotary shafts 5 and 6 are set so as to pass through the centers of the first surface I and the sixth surface VI in the first posture position, and similarly, the second surface II and the second surface in the second posture position. It is set to pass through the center of the fifth surface V and the center of the third surface III and the fourth surface IV in the third posture position.
As a result, when winding the yarn on each of the above surfaces, the variation in the winding speed can be minimized, and the variation in tension applied to the yarn can be minimized. For this reason, it becomes possible to wind up stably, without a thread | yarn being cut | disconnected.

  As the locking means 22, for example, a rotary actuator with a brake can be used. When the cubic member 21 is converted between the first posture position, the second posture position, and the third posture position, And the cube member 21 is rotated 120 degrees around the tilt axis 9 by a rotary actuator, and a brake is applied at that position to fix the cube member 21 to the tilt shaft 9.

Either one of the rotating shafts 5 and 6 is linked to a servo motor (not shown) that rotates the shaft, and the cube member 21 is in each of the first posture position, the second posture position, and the third posture position. As the rotary shaft 5 or 6 rotates, the holding members 7 and 8 and the inclined shaft 9 are rotated together.
The operation of the servo motor is controlled by a control device (not shown), and the servo motor is rotated by a rotation position detecting means such as a tachometer (not shown) provided on one of the rotation shafts 5 and 6. The rotational angle position of the cube member 21 with respect to the axis line of the shafts 5 and 6 can be detected.
Although not shown, the yarn feeding device that supplies the yarn to the cubic member 21 includes a reciprocating mechanism that can reciprocate the yarn from one end to the other end of one side of the cubic member 21. As a result, the yarn is reciprocated a plurality of times at regular intervals across the above-mentioned surfaces so as to be wound evenly.

In the above configuration, the cube member 21 is in the first posture position shown in FIG. 1, that is, the second surface II, the third surface III, the fourth surface IV, and the fifth surface V are on the axes of the rotation shafts 5 and 6. In a state of being parallel to each other, it is rotated by the servo motor via the rotary shaft 5 or 6, thereby extending over the second surface II, the third surface III, the fourth surface IV and the fifth surface V. Winding the thread.
As described above, the yarn is reciprocated a plurality of times along each side of the cubic member by the reciprocating mechanism of the yarn feeding device, and is uniformly wound around the four surfaces of the cubic member 21, whereby the yarn on the four surfaces is wound. When winding is completed, it is detected by a sensor (not shown) that the yarn has moved to one end of the side, that is, the reciprocating mechanism of the yarn feeding device has moved to one end.
In this state, the locking means 22 is actuated to release the fixation of the cube member 21 with respect to the tilt shaft 9, and the cube member 21 is rotated 120 degrees around the tilt shaft 9 as shown in FIG. In this state, the cubic member 21 is fixed to the inclined shaft 9 by the locking means 22.

In this state, as described above, the cubic member 21 is in the second posture position, so that the yarn is wound around the first surface I, the third surface III, the fourth surface IV, and the sixth surface VI. become.
At this time, the yarn is supplied to the cube member 21 with the reciprocating mechanism of the yarn feeding device moved to one end, and when the posture of the cube member 21 is converted from the first posture position to the second posture position, The reciprocating mechanism of the yarn feeding device is actuated again, and the yarn is reciprocated a plurality of times along the side to be uniformly wound around the cube member 21.
Of course, the same control is performed when the cube member 21 is converted from the second posture position to the third posture position. In the third posture position shown in FIG. 3, the first surface I, the second surface II, The yarn is wound around the fifth surface V and the sixth surface VI.

Thereafter, the same operation is repeated, and the cubic member 21 is sequentially switched from the first posture position to the third posture position a plurality of times, so that the threads are wound alternately and evenly on each surface of the cubic member 21. become.
More specifically, for example, regarding the fourth surface VI, the yarn is wound around the fourth surface VI along the line L described in the fourth surface VI in the first posture position shown in FIG. become. On the other hand, in the second posture position shown in FIG. 2, the yarn is wound around the fourth surface VI in a direction perpendicular to the line L described on the fourth surface VI.
