The second clamping portion 133 has a cylindrical shape, and is formed of, for example, a wear-resistant metal such as SUS. The second clamping portion 133 clamps the first yarn YA and the second yarn YB in the clamping direction. The second clamping portion 133 includes a fixed side column 133x and a moving side column 133y. The fixed side column 133x and the movable side column 133y are arranged in such a way that their respective end faces face each other in the clamping direction. The fixed side column 133x is fixed to the support part 132. The movable side column 133y is provided on the support portion 132 so as to be movable in the clamping direction.

In the second clamping portion 133, the movable side cylinder 133y moves close to the fixed side cylinder 133x, and the end surface of the fixed side cylinder 133x abuts against the end surface of the movable side cylinder 133y, thereby being between them Clamp the first yarn YA and the second yarn YB. In the second clamping portion 133, the movable side cylinder 133y moves away from the fixed side cylinder 133x, and a gap is formed between the end surface of the fixed side cylinder 133x and the end surface of the movable side cylinder 133y, thereby releasing the clamping hold. The clamping of the second clamping portion 133 and the release of the clamping can be realized by various known techniques, for example, can be realized by an air drive using air supplied from the outside or a cam mechanism. The second nipping portion 133 urges the first yarn YA and the second yarn YB in the nipping direction by an urging member (not shown) such as a spring to nip. The force of clamping the first yarn YA and the second yarn YB by the second clamping portion 133 is equal to the force of clamping the first yarn YA and the second yarn YB by the first clamping portion 123.

The fourth clamping portion 137 is arranged on the other side of the second clamping portion 133 in the penetrating direction. The fourth clamping portion 137 has a cylindrical shape, and is formed of, for example, a wear-resistant metal such as SUS.

In the fourth clamping portion 137, the movable side cylinder 137y moves away from the fixed side cylinder 137x, and a gap is formed between the end surface of the fixed side cylinder 137x and the end surface of the movable side cylinder 137y, thereby releasing the clamping . The clamping of the fourth clamping portion 137 and the release of the clamping can be achieved by various known techniques, for example, can be achieved by an air drive using air supplied from the outside or a cam mechanism. The 4th clamping part 137 clamps the 2nd yarn YB by urging members (illustration omitted), such as a spring, by urging|biasing in a clamping direction. The force of clamping the second yarn YB by the fourth clamping portion 137 is smaller than the force of clamping the first yarn YA and the second yarn YB by the second clamping portion 133. The force of clamping the second yarn YB by the fourth clamping portion 137 is equal to the force of clamping the first yarn YA by the third clamping portion 127.

The second cutter 139 cuts the first yarn YA at a position on the other side of the penetrating direction of the second clamping portion 133. The second cutter 139 is provided between the second clamping portion 133 and the fourth clamping portion 137 of the supporting portion 132 so as to be movable along the clamping direction. The second cutter 139 and the second clamping portion 133 are interlocked with the movement of clamping the first yarn YA and the second yarn YB, and move to a position where the first yarn YA can be cut. Specifically, as shown in FIGS. 18A and 18B, the second cutter 139 is connected to the movement side column 133y of the second clamping portion 133. The second cutter 139 is positioned so as to straddle the first yarn YA in a state where the first yarn YA and the second yarn YB are clamped by the second clamping portion 133. In this case, if the first yarn YA is moved to the side away from the second clamping portion 133 in the insertion direction, the second cutter 139 cuts the first yarn YA. On the other hand, the second cutter 139 is located at a position away from the first yarn YA in the clamping direction in a state where the second clamping portion 133 has released the clamping of the first yarn YA and the second yarn YB. .

As shown in FIGS. 15, 17 and 20, the shutter mechanism 140 constitutes a shutter portion capable of closing at least a part of the cavity 114 of the wiring portion 66a. When the shutter mechanism 140 entangles the first yarn YA and the second yarn YB by the threading portion 66a, the separation threading portion 66a of the first clamping portion 123 and the second clamping portion 133 in the closed chamber 114 is relatively Far from either side.

The other side of the first stopper follower 157 abuts on the bottom surface of the stopper annular groove 153. One side of the second shutter follower 158 is connected to the base end of the second shutter 142 of the shutter mechanism 140. The other side of the second shutter follower 158 abuts on the bottom surface of the shutter ring groove 153. The follower 157 for the first shutter and the follower 158 for the second shutter move according to the height of the bottom surface of the annular groove 153 for the shutter. The follower 157 for the first barrier and the follower 158 for the second barrier are urged by the torsion spring 159a so as to swing in the opening direction in which the first barrier 141 and the second barrier 142 are opened. .

A raised portion 156 is formed on the bottom surface of the annular groove 153 for the shutter. If each of the first brake follower 157 and the second brake follower 158 covers the raised portion 156, the first brake follower 157 and the second brake follower 158 are respectively By swinging in the closing direction (the swinging direction opposite to the opening direction), each of the first shutter 141 and the second shutter 142 is in the closed state. If each of the first stopper follower 157 and the second stopper follower 158 abuts on the bottom surface of the stopper ring groove 153 except for the raised portion 156, the first stopper The follower 157 and the follower 158 for the second shutter respectively swing in the opening direction, so that each of the first shutter 141 and the second shutter 142 is in an open state. The annular groove 153 for the shutter rotates the cylindrical cam 150, whereby the follower 157 for the first shutter and the follower 158 for the second shutter are oscillated as required, thereby allowing the following first gear The gate 141 and the second gate 142 are opened and closed.

The motor 160 is a driving source that drives the cylindrical cam 150 to rotate. The motor 160 is supported by the frame 102. The motor 160 is rotated by a control unit (not shown). As described above, the cylindrical cam 150, the follower 154 for the first clamping portion, the follower 155 for the second clamping portion, and the motor 160 are configured to follow each of the first clamping portion 123 and the second clamping portion 133.

Next, an example of the operation of the connector 66 will be described with reference to FIGS. 20A to 28.

In addition, in FIGS. 20A to 28, for convenience, the movement of the supporting parts 122, 132 caused by the swing of the clamping mechanisms 66b, 66c is shown as a linear movement in the penetrating direction. In the following description, for the sake of convenience, one side of the penetration direction is referred to as the "left side", and the other side in the penetration direction is referred to as the "right side". The movement of the supporting portion 122 corresponds to the movement of the first clamping portion 123 and the third clamping portion 127, and the movement of the supporting portion 132 corresponds to the movement of the second clamping portion 133 and the fourth clamping portion 137.

As shown in FIG. 20A, in the initial state, the first to fourth clamping portions 123, 133, 127, and 137 are in a state where the clamping is released, the supporting portion 122 is close to the connecting portion 66a, and the supporting portion 132 and the connecting portion 66a Close. The first shutter 141 and the second shutter 142 are in an open state. In the initial state, for example, by the catching and guiding mechanism (yarn catching and guiding part) 61, the first yarn YA and the second yarn YB are caught and inserted into the chamber 114, and the first yarn YA and the second yarn YB are inserted to the first Between the fixed side cylinders 123x, 133x, 127x, 137x and the movable side cylinders 123y, 133y, 127y, 137y of the first to fourth clamping parts 123, 133, 127, 137.

As shown in FIG. 20B, the first clamping portion 123 and the second clamping portion 133 are placed in a clamping state, and the first yarn YA is clamped by each of the first clamping portion 123 and the second clamping portion 133 And the second yarn YB. At this time, the first cutter 129 and the second cutter 139 are interlocked, the first cutter 129 moves on the second yarn YB, and the second cutter 139 moves on the first yarn YA.

As shown in FIG. 21A, the yarn end side of the first yarn YA is pulled up so as to be away from the second clamping portion 133, and the yarn end side of the second yarn YB is pulled up so as to be away from the first clamping portion 123. Thereby, the first yarn YA is cut by the second cutter 139, and the second yarn YB is cut by the first cutter 129.

As shown in FIG. 21B, the third clamping portion 127 and the fourth clamping portion 137 are placed in a clamping state, the first yarn YA is clamped by the third clamping portion 127, and the fourth clamping portion 137 Hold the second yarn YB. As shown in FIG. 22A, each of the support parts 122 and 132 is moved away from the connection part 66a. Thereby, in a state where the first yarn YA and the second yarn YB are clamped by the first clamping portion 123 and the second clamping portion 133, the first clamping portion 123 and the second clamping portion 133 The interval (distance in the penetrating direction) is enlarged by moving the same in the penetrating direction, so that the first yarn YA and the second yarn YB between the first clamping portion 123 and the second clamping portion 133 extend, for example, to 1.6 times (Extension processing).

As shown in FIG. 22B, each of the support parts 122 and 132 is moved so as to approach the connection part 66a. Thereby, in a state in which the first yarn YA and the second yarn YB are clamped by each of the first clamping part 123 and the second clamping part 133, the first clamping part 123 and the second clamping part 133 are clamped. The interval between the portions 133 is narrowed so that it moves in the penetrating direction, so that the stretched portion of the first yarn YA and the second yarn YB that is stretched by the stretching process is loosened. Thereafter or in parallel therewith, the extension portions of the first yarn YA and the second yarn YB are entangled by the connecting portion 66a (first entanglement treatment). As shown in FIG. 23A, the supporting portion 122 is moved to the left to remove the slack of the entangled portion M1 of the first yarn YA and the second yarn YB formed by the first entanglement process.

As shown in FIG. 23B, the clamping of the first yarn YA and the second yarn YB of the second clamping portion 133 is released. The support portion 122 is further moved to the left, and the first clamping portion 123 and the third clamping portion 127 are moved to the left. Thereby, the first yarn YA and the second yarn YB are also pulled by the first clamping portion 123 and the third clamping portion 127, so that the first yarn YA and the second yarn YB are shifted to the left. That is, in a state where the first yarn YA and the second yarn YB are clamped by the first clamping part 123 and the clamping of the second clamping part 133 is released, the first clamping part 123 is moved to the left. As a result, the first portion K1 of the first yarn YA and the second yarn YB clamped by the second clamping portion 133 before the release is moved to the left (first movement processing). As a result, it is assumed that the first portion K1 is inserted into the cavity 114 of the connection portion 66a.

As shown in FIG. 24A, the support portion 122 that moves to the left returns only to the right by a movement amount less than its movement amount. Thereby, the entangled part M1 and the 1st part K1 are loosened. The first shutter 141 is set to a closed state, and the second shutter 142 is set to an open state. As shown in FIG. 24B, the first portion K1 of the first yarn YA and the second yarn YB is entangled by the connecting portion 66a to form an entangled portion M2 (second entanglement process). In the second entanglement process, the left side of the chamber 114 is closed by the first shutter 141 of the shutter mechanism 140 (any one of the first clamping portion 123 and the second clamping portion 133 is farther from the wiring portion 66a) One side).

As shown in FIG. 25A, the first shutter 141 is set to an open state, and the support portion 122 is moved to the left to remove the slack of the tangled part M1 and the tangled part M2. As shown in FIG. 25B, the second clamping portion 133 is placed in a clamping state, and the supporting portions 122 and 132 are moved to the right at the same time, so that the first to fourth clamping portions 123, 133, 127, and 137 are simultaneously moved to the right. Move to the right.

As shown in FIG. 26A, the clamping of the first yarn YA and the second yarn YB by the first clamping portion 123 is released. The support portion 132 is further moved to the right, and the second clamping portion 133 and the fourth clamping portion 137 are moved to the right. Thereby, the first yarn YA and the second yarn YB are also pulled by the second clamping portion 133 and the fourth clamping portion 137, so that the first yarn YA and the second yarn YB are shifted to the right. That is, in a state where the first yarn YA and the second yarn YB are clamped by the second clamping portion 133 and the clamping of the first clamping portion 123 is released, the second clamping portion 133 is moved to the right. As a result, the second portion K2 of the first yarn YA and the second yarn YB clamped by the first clamping portion 123 before the release is moved to the right (second movement processing). As a result, it is assumed that the second portion K2 is inserted into the cavity 114 of the connection portion 66a.

As shown in FIG. 26B, the support portion 132 that moves to the right returns only to the left by an amount less than the amount of movement. Thereby, the entangled parts M1, M2 and the second part K2 are loosened. As shown in FIG. 27A, the first shutter 141 is set to an open state, and the second shutter 142 is set to a closed state. As shown in FIG. 27B, the second portion K2 of the first yarn YA and the second yarn YB is entangled by the connecting portion 66a to form an entangled portion M3 (third entanglement process). In the third entanglement process, the right side of the chamber 114 is closed by the second shutter 142 of the shutter mechanism 140 (any one of the first clamping portion 123 and the second clamping portion 133 is farther from the wiring portion 66a) One side). Then, the second shutter 142 is set to an open state.

As shown in FIG. 28, each of the support portions 122, 132 is moved relative to its initial position to a position where the portions extended by the stretching process are equally distributed. Finally, all the clamping of the first to fourth clamping parts 123, 133, 127, 137 is released, and the end is completed.

However, during wiring, for example, due to the influence of the air (fluid) ejected from the ejection hole 116a, the first yarn YA and the second yarn YB can easily pass from the first clamping portion 123 and the second clamping portion in the chamber 114 In 133, any side farther from the connection part 66a (hereinafter, also referred to as "far side") jumps out. Therefore, in the connector 66, when wiring, the shutter mechanism 140 is used to close the far side of the chamber 114, so that, for example, the air from the injection hole 116a is actively directed to the side of the chamber 114 opposite to the far side. By flowing, the air can also suppress the first yarn YA and the second yarn YB from jumping out of the far side of the cavity 114. In other words, it is possible to prevent the first yarn YA and the second yarn YB from jumping out of the cavity 114 of the threading portion 66a during threading.

The adapter 66 includes an opening and closing mechanism 180 for opening and closing the shutter mechanism 140. In this configuration, the opening and closing mechanism 180 can be used to open and close the shutter mechanism 140.

In the adapter 66, the opening and closing mechanism 180 has: a cylinder cam 150; first and second brake followers 157, 158, which are connected to the shutter mechanism 140, and a ring-shaped brake along the cylinder cam 150 The bottom surface of the groove 153 is driven; and a motor 160, which drives the cylinder cam 150 to rotate. In this case, the shutter mechanism 140 can be opened and closed by the opening and closing mechanism 180 as a cam mechanism.

In the connector 66, the shutter mechanism 140 includes: a first shutter 141, which is arranged on one side of the connecting portion 66a in the through direction; and a second shutter 142, which is arranged on one side of the connecting portion 66a in the through direction The other side. In this case, the far side of the chamber 114 can be closed by setting any one of the first barrier 141 and the second barrier 142 to a closed state.

The splice 66 includes a moving mechanism 170 that moves each of the first clamping portion 123 and the second clamping portion 133 in the penetrating direction. The moving mechanism 170 performs a first moving process, which is a state in which the first yarn YA and the second yarn YB are clamped by the first clamping portion 123 and the clamping of the second clamping portion 133 is released Next, the first clamping portion 123 is moved to one side of the penetrating direction, so that the first portion K1 of the first yarn YA and the second yarn YB clamped by the second clamping portion 133 before the release is moved toward Move on one side of the penetrating direction. Before the first movement process, the threading section 66a performs the first entanglement process in which the first yarn YA and the second yarn YB are entangled by the threading section 66a, and after the first movement process, the first yarn YA and the second yarn YB are intertwined. The second entanglement process of the first part K1 entanglement in the second yarn YB. In the shutter mechanism 140, in the second entanglement process, the first shutter 141 is in the closed state and the second shutter 142 is in the open state. Thereby, when the second entanglement process is performed, the first yarn YA and the second yarn YB can be suppressed from jumping out of the cavity 114 of the connecting portion 66a.

In the splicer 66, the moving mechanism 170 performs a second moving process after the second entanglement process. The second moving process is performed when the first yarn YA and the second yarn YB are clamped by the second clamping portion 133 and In the state where the clamping of the first clamping portion 123 is released, the second clamping portion 133 is moved to the other side of the penetrating direction, so that the first clamping portion of the first yarn YA and the second yarn YB is The second part K2 clamped by 123 before the release moves to the other side of the penetrating direction. After the second movement process, the connecting portion 66a is subjected to a third entanglement process in which the second part K2 of the first yarn YA and the second yarn YB is entangled. In the shutter mechanism 140, in the third entanglement process, the first shutter 141 is in an open state and the second shutter 142 is in a closed state. Thereby, when the third entanglement process is performed, the first yarn YA and the second yarn YB can be prevented from jumping out of the cavity 114 of the connecting portion 66a.
