Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a large number of axoneme groups extending perpendicularly to the plane through a number of points arranged in a two-dimensional manner on a plane; The present invention relates to an apparatus for producing a three-dimensional fabric having a structure consisting of entwined threads that are entangled with the axoneme groups along a plane along an arbitrary route, and a method for producing a three-dimensional fabric using the apparatus.

In general, three-dimensional textiles are special textiles made of threads extending in three mutually orthogonal directions: warp, width, and height, and can be used as they are, or as fiber-reinforced composite materials with resin or inorganic materials as a matrix. Used as a reinforcing member. In particular, the composite material has excellent mechanical properties such as shear strength, and thermal properties.
It is used as a heat-resistant member for high-speed flying objects such as rockets. It is also expected to be widely used in fields that require various lightweight structures.

BACKGROUND TECHNOLOGY As a method for manufacturing this type of three-dimensional fabric,
For example, the one described in Japanese Patent Publication No. 61-1538 is known. In this device, a large number of carriers are arranged on a carrier fixed plate, a shaft thread is inserted through the central shaft of the carriers, a bobbin containing a entangled thread is arranged between the carriers, and the carrier receives the bobbin. A carrier arm that can be opened and closed for transferring the bobbin is provided, and the carrier arm is rotated around the carrier shaft to transfer the bobbin to an adjacent carrier, thereby moving the bobbin along an arbitrary path.

However, in this invention, each carrier can transfer bobbins to and from an adjacent carrier only at the position of the carrier arm.
Therefore, the carrier receiving the bobbin must have its carrier arm in the bobbin receiving position prior to receiving the bobbin.

In addition, one carrier must rotate a predetermined angle from the time it receives the bobbin until it passes the bobbin to the next carrier, and in that rotation path, the carrier arm of the adjacent carrier is rotated toward the first carrier. Otherwise, the bobbin will collide with the carrier arm and cannot operate properly.

In this type of device, the moving path of the carrier is stored in advance in a computer, etc., and the bobbin is transferred and the carrier arm is rotated according to the program.In this program, the bobbin is transferred between specific carriers. It is not enough to control only the rotation of the carrier that grips the bobbin; it is also necessary to appropriately control the carrier, which is completely unrelated to the current operation, making the program extremely complicated.

Therefore, it has been devised that the gripping means in the carrier is made up of two disks that can be opened and closed in the vertical direction, and a gripping disk provided on the bobbin is held between the disks by pressure. According to this, the carrier has no directionality, and it is only necessary to control the opening and closing of the carrier gripping means involved in bobbin delivery and the rotation of the carrier that grips the bobbin for the time being.
The structure is simple and the control program is simple, which is extremely convenient.

Problems to be Solved by the Invention However, in a device equipped with this type of gripping means, the gripping means has no directionality and can grip the bobbin in any direction, so the advantage is that the gripping means can be easily controlled. However, there is a drawback in that all carriers other than the carrier gripping the bobbin must have their gripping means in a released state. That is, if the carrier along the bobbin passage path is closed, the bobbin will collide with the carrier and cannot pass.

By the way, when this type of device is used, the gripping means of all the carriers are interlocked and each carrier is rotated back and forth through an angle corresponding to the angle from one adjacent carrier to the next adjacent carrier. Then, only the gripping means of the carrier that is to move the bobbin is in a gripping state only when the gripping means rotates in the direction in which the bobbin is to be moved, and in this gripping state, the carrier is rotated together with the bobbin gripping means repeatedly, and the bobbin is It is considered to move along a desired route. According to this method, since it is sufficient to control only the opening and closing of the gripping means, the control means can be further simplified.

However, in this method, when the gripping means rotates in the direction of movement of the bobbin, it grips the bobbin, but when it rotates in the opposite direction, the gripping means is in a released state, and the bobbin is not gripped by either carrier. Not done. Therefore, there is nothing to support the bobbin, and the bobbin falls off the gripping means, making it impossible to weave. Furthermore, even if the released bobbin is placed on a carrier support plate, it is likely to topple over due to the tension of the entangled yarn being pulled out from the bobbin, the vibration of the carrier, etc., and weaving cannot be continued.

Another weaving method involves arranging two or more bobbins on the device and moving each bobbin along the same or different paths by a carrier gripping means to increase the weaving speed of the three-dimensional fabric. is considered.

However, in this case, two or more bobbins may converge in the vicinity of a single carrier as they move along their path. For example, this state is shown in FIG.

In Figure 3, A is the carrier, and
They are arranged horizontally in a matrix. In this matrix, carrier A of X stage and Y column is A _XY
It shall be displayed as . Curves Ba and Bb are the paths of the two bobbins Ca and Cb.

Assume that bobbins Ca and Cb are at the positions shown in the figure at a certain moment. In other words, bobbin Ca is carrier A ₃₁
The bobbin Cb is held by the carrier A ₄₂ and is meandering along the carrier A of the second line, following the bobbin Ca.

Continuing from this state, the bobbin Ca is further rotated by 90 degrees by the carrier A ₃₁ and the bobbin Cb by the carrier A ₄₂ , and then delivered to the carriers A ₂₁ and A ₃₂ , respectively. Further, each bobbin Ca, Cb is rotated 180° by carrier A ₂₁ and carrier A ₃₂ , and then rotated by carrier A 21 and carrier A 32.
A ₁₁ and delivered to carrier A ₂₂ .

After that, the bobbin Ca held by carrier A ₁₁ is
After being rotated 90 degrees, the bobbin Cb is transferred to carrier A ₁₂ , but the bobbin Cb remains held by carrier A ₂₂ .
It can be rotated 270°. By the time the bobbin Cb passes between _the carrier A ₂₂ and the carrier A ₁₂ as the carrier A 22 rotates, the carrier
The gripping means _A12 grips and closes the bobbin Ca, and the bobbin Cb cannot pass therethrough.

Furthermore, if the gripping means of the carrier A ₁₂ closes while the bobbin Cb is passing between the carriers A ₁₂ and A ₂₂ , the bobbin Cb will be gripped by the carrier A ₁₂ by the gripping means and will not move. become unable to do so.

In such a case, it is necessary to temporarily release the carrier that should be holding the bobbin to allow another bobbin to pass, but as mentioned above, if all the carriers that should be holding the bobbin are released, As mentioned above, the bobbin falls or falls, making it impossible to continue weaving.

The present invention has been made in view of the above circumstances, and includes a weaving device for a three-dimensional fabric that can be made to stand still between carriers without holding a bobbin in the carrier, and a three-dimensional fabric weaving device using the weaving device. The object is to provide a method for weaving original fabrics.

Means for Solving the Problems The device of the present invention arranges a large number of points on a plane with a two-dimensional spread, and arranges a large number of axoneme groups extending perpendicularly to the plane through each of the points. and,

The shaft yarn is inserted into a carrier shaft, and a bobbin on which the entangled yarn is wound is arranged between the carriers, and the carrier is provided with a gripping means capable of gripping and releasing the bobbin, and the gripping means is inserted into the carrier shaft. The bobbin is rotatable around a carrier shaft, the bobbin is gripped by the gripping means and rotated around the carrier, and the bobbin is transferred by the gripping means between the carrier and an adjacent carrier, and the bobbin is moved along an arbitrary route. In the apparatus for weaving a three-dimensional fabric by moving the entanglement yarn fed out from the bobbin along the axis yarn, the gripping means is provided rotatably about the carrier shaft. It consists of a first disk and a second disk that can be moved into and out of contact with the first disk, and the gripping disk provided on the bobbin is held between the first disk and the second disk by pressure. In addition, when the holding means of the two carriers located on both sides sandwiching the bobbin are both in a released state, a means is provided for fixedly holding the bobbin with respect to the carrier fixing plate. It is something.

Further, the first method of the present invention includes a large number of axoneme groups extending perpendicularly to the plane through a large number of points arranged with a two-dimensional spread on a plane, and a plurality of axoneme groups extending on the plane. This is a method for manufacturing a three-dimensional fabric having a structure consisting of entwined threads that are entangled along arbitrary routes, in which a large number of carriers with shaft threads inserted through them are arranged on a carrier fixed plate, and the carriers are rotatable and The bobbin containing the entangled yarn is gripped by two disk-shaped gripping means provided vertically and freely openable and closed, and the operation of rotating the gripping means and successively transferring the bobbin to the gripping means of the adjacent carrier is repeated. In the method of weaving a three-dimensional fabric by weaving entangled yarns into the axle threads, the gripping means of all carriers are interlocked to move from one adjacent carrier in each carrier to the next adjacent carrier. The carrier is rotated reciprocatingly through an angle corresponding to the angle corresponding to the angle of , and only the gripping means of the carrier that is to move the bobbin is held in a gripping state only when the gripping means rotates in the direction in which the bobbin is to be moved. The present invention is characterized in that all carriers other than the above are in a released state, and when the bobbin is not gripped by any of the carrier gripping means, the bobbin is held fixedly with respect to the carrier fixing plate, and the second The method consists of a large number of axoneme groups extending perpendicularly to the plane through a large number of points arranged in a two-dimensional spread on a plane, and an arbitrary path being traced to the axoneme groups on the plane.

The bobbin containing the entangled yarn is gripped by the two disc-shaped gripping means, and the gripping means are rotated and the bobbin is sequentially transferred to the gripping means of the adjacent carrier, which is repeated. On the other hand, in a method of weaving a three-dimensional fabric by weaving entangled threads, a plurality of the bobbins are arranged on the carrier fixed plate, and each bobbin is moved by the carrier's gripping means following the same or different paths. , while one carrier is gripping one bobbin, all carriers adjacent to the one carrier are in a released state, and if there is another bobbin in the gripping position with respect to the adjacent carrier, the corresponding bobbin is Another bobbin is fixedly held with respect to a carrier fixing plate between the adjacent carrier and a carrier other than the one carrier.

Function Next, the function of the device of the present invention will be explained. According to the device of the present invention, the carrier gripping means includes a first disc and a second disc, the first disc is rotatable around the carrier shaft, and both discs can be moved into and out of contact with each other. By approaching the first disk, the gripping disk provided on the bobbin is held between the first disk and the second disk, and in this state, the first disk and the second disk are held together. By rotating as a unit, the bobbin is rotated around the carrier, and the bobbin is transferred to adjacent carriers one after another, thereby moving the bobbin along a predetermined path.

In the process of movement, when the holding means of the two carriers located on both sides of the bobbin are in a released state, the bobbin is fixedly held with respect to the carrier fixing plate by the holding means.

Further, in the method according to claim 2 of the present invention, for example, to explain the step of moving the bobbin C from carrier A ₄₁ to carrier A ₂₁ in FIG. 3, bobbin C is located between carrier A ₅₁ and carrier A ₄₁ , and each Carrier A is rotated back and forth by 90 degrees. The bobbin C is then held by the holding means of the carrier A ₄₁ and rotated 90 degrees clockwise. Next, the gripping means of the carrier A ₄₁ releases the bobbin C, the bobbin C is fixedly held with respect to the carrier stationary platen, and the gripping means of the carrier A ₄₁ is rotated 90 degrees counterclockwise.

Next, the holding means of carrier A ₄₁ is again held by bobbin C.
Grip it, rotate it 90 degrees clockwise, and then attach it to the carrier again.
The gripping means A ₄₁ releases the bobbin C to hold it on the carrier stationary platen.

Next, grip the bobbin C with the gripping means of the carrier A ₃₁ , rotate it 90 degrees counterclockwise, release the grip on the bobbin, hold it on the carrier fixing plate, and rotate the bobbin clockwise.
Rotate 90°. And again carrier A ₃₁ is bobbin C
When the bobbin C is gripped and rotated 90 degrees counterclockwise, the bobbin C moves to between the carrier A ₂₁ and the carrier A ₃₁ .

By repeating this process, carrier A
As the bobbin C moves in a meandering manner, the bobbin C travels along an arbitrary path while entwining the threads with the axis threads, thereby weaving a three-dimensional fabric.

Next, in the method of the invention according to claim 3, the steps in FIG.
When Ca and bobbin Cb come between carriers A ₁₁ and A ₂₁ and between carriers A ₂₂ and A ₃₂ , respectively, bobbins Ca and Cb are held by carriers A ₁₁ and A _22, respectively. and rotate around it.

Here, when the carrier A ₁₁ rotates 90 degrees, it releases its gripping means and releases its grip on the bobbin Ca.
Then, carrier A ₂₂ adjacent to carrier A ₁₂ , which should receive the bobbin Ca, closes and the bobbin Ca is transferred.
Because it grips Cb, carrier A ₁₂ cannot close and does not grip bobbin Ca.
The bobbin Ca is fixedly held on a carrier fixed plate.

Then, the gripping means of carrier A ₂₂ continues to rotate, and bobbin Cb moves to between carriers A ₂₂ and carrier A 23, where bobbin Cb is removed from carrier A 22 and carrier A ₂₃ .
When the gripping means of carrier A ₂₂ is opened after delivery to A ₂₃ ,
Then, the gripping means of carrier A ₁₂ closes and the bobbin Ca is removed.
grasp.

In this way, the bobbin Cb, which has a short path to pass, overtakes the bobbin Ca, which has a long path, and then the carrier transfers the bobbins Ca and Cb one after another to move the bobbin.
