Description

Winding device

The present invention relates to a winding device.

Patent Document 1 discloses a false twisting machine including a false twisting device that falsely twists a yarn supplied from a yarn supply unit, and a winding device that winds the falsely twisted yarn. The winding device has a cradle that rotatably supports a set of bobbin holders, and winds the yarn around the bobbin (the paper tube of Patent Document 1) attached to the bobbin holder to form a package.

When a full package is formed in such a winding device, the package is unloaded from the cradle and a new bobbin is supplied to the cradle. The winding device described in Patent Document 2 (the doffing device of Patent Document 2) has a package storage part (the guide rail of Patent Document 2) that supports the package detached from the cradle, and stores a plurality of packages in an array. A stocker for empty tubes supplied to the cradle (paper tube stocker of Patent Document 2).

In the winding device of Patent Document 2, the stocker is swingably supported by a rotation shaft provided below the stocker via a support bracket. The stocker is configured to be positioned at a standby position (the position shown in Fig. 2) above the package storage portion when winding the yarn, and is moved to the position by swinging about the rotation axis when the bobbin is supplied to the cradle. The supply position is lower than the standby position and on the right side of the paper in FIG. 2 of Patent Document 2 (hereinafter, simply referred to as the right side. In addition, the left side of the paper is simply referred to as the left side). [Prior technical literature] [Patent Document]

[Problem to be solved by the invention]

In the device of Patent Document 2, as shown in FIG. 2 , when the stocker is in the standby position, the support bracket that supports the stocker is in a state of being inclined upward and leftward from the rotation axis. On the other hand, when the stocker is in the supply position, the support bracket swings clockwise from the state shown in FIG. 2 , and the support bracket becomes a state inclining obliquely upward and rightward from the rotation axis. That is, while the stocker is moving from the standby position to the supply position, the support bracket changes from a state tilted diagonally upward to the left, once to a vertical direction, and then to a state tilted diagonally upward right. Then, the stocker connected to the support bracket passes through a position above both the standby position and the supply position while moving from the standby position to the supply position. Therefore, it is necessary to secure space above the winding device so that the stocker does not interfere with other components during movement from the standby position to the supply position. However, ensuring such a space increases the actual height of the winding device.

An object of the present invention is to suppress an increase in the height of a winding device. [Technical means to solve problems]

The winding device of the present invention is equipped with a cradle that can rotatably support the bobbin holder. By winding the yarn on the bobbin held by the bobbin holder to form a package, the package can be It is released from the holding of the above-mentioned bobbin holder; a package storage part stores the above-mentioned package released from the above-mentioned cradle; a stocker stores the above-mentioned bobbin for supply to the above-mentioned cradle; and a moving mechanism makes the above-mentioned storage The feeder moves between a standby position and a supply position for supplying the bobbin to the cradle in a release position in which the bobbin holder is released from holding the package, and the package storage portion is The vertical plane of the axis of the bobbin holder supported by the cradle in the release position is arranged on one side, and the stocker in the standby position is arranged on one side with the vertical plane as a boundary. On the other side, the moving mechanism linearly moves the stocker between the standby position and the supply position.

According to the present invention, the stocker can move linearly from the standby position to the supply position. Therefore, while the stocker is moving from the standby position to the supply position, it does not pass through a position above both the standby position and the supply position, and there is no need to secure a separate space above the winding device. However, even when the stocker is moved linearly, for example, when the stocker is arranged above the package storage part as in Patent Document 2, the position of the stocker still becomes high, and the height of the winding device There are limits to size reduction. The reason for this is that the package released from the cradle is conveyed to the package storage part through the lower part of the stocker, so the distance between the stocker and the package storage part must be increased to the extent that the package can pass. In this regard, in the present invention, the stocker is arranged on the opposite side of the package storage portion with the vertical plane as a boundary. Therefore, the stocker can be disposed at a lower position and the stocker cannot pass above both the standby position and the supply position. Therefore, the height of the winding device can be effectively suppressed.

In the winding device of the present invention, it is preferable that a restriction portion is provided at the front end of the cradle in the hopper close to the cradle in the release position, and the restriction portion can prevent the cradle from being stored in the hopper. The restricting portion is switched between a restricted state in which the bobbin is detached from the hopper and a released state in which the restricted state is released, and the restricting portion enters the released state when the hopper reaches the supply position.

According to the present invention, before the stocker reaches the supply position, the bobbin can be prevented from falling off from the stocker by the restricting portion in the restricted state. Furthermore, when the stocker reaches the supply position, the restricting portion is in the released state, so the supply of the bobbin from the stocker to the cradle is not hindered by the restricting portion. This makes it possible to reliably store the bobbin in the stocker and to appropriately supply the bobbin from the stocker to the cradle.

In the winding device of the present invention, it is preferable that the stocker has a first rotation axis along the axial direction of the bobbin holder, and the restricting portion has the above-mentioned cradle supported by the cradle in the release position. The abutment portion where the bobbin holder abuts, and the restriction portion is configured such that as the stocker moves from the standby position to the supply position, the abutment portion is pushed by the bobbin holder, whereby the first The rotating shaft rotates in the first direction about the center to switch from the restricted state to the released state. The restricting portion is configured such that as the stocker moves from the supply position to the standby position, the contact portion and the bobbin The contact of the bracket is released, whereby the bracket rotates in a second direction opposite to the first direction about the first rotation axis, thereby switching from the released state to the restricted state.

According to the present invention, the release state and the restriction state of the restriction part can be switched depending on whether the contact portion is brought into contact with the bobbin holder as the stocker moves. Therefore, a drive source for switching the state of the restriction section is not required.

In the winding device of the present invention, it is preferable that the stocker has a stopper capable of being contacted by the restricting portion rotating in the first direction, and when the stocker reaches the supply position, the contact portion The restriction portion, which is pressed by the bobbin holder and rotates in the first direction, is restricted from further rotating in the first direction by contacting the stopper.

According to the present invention, the restricting portion that rotates in the first direction as the stocker moves is restricted from further rotating in the first direction by contacting the stopper. Therefore, the contact portion of the restricting portion is restricted from being further pushed by the bobbin holder, that is, further movement of the stocker is restricted. This can prevent the stocker from moving further beyond the supply position, and can appropriately supply the bobbin from the stocker to the cradle.

In the winding device of the present invention, it is preferable that the hopper is provided with a second restricting portion that suppresses storage when the hopper reaches the supply position and the restricting portion enters the released state. The bobbin in the stocker exceeds the bobbin holder and flies out.

When the stocker moves from the standby position to the supply position, inertial force acts on the bobbin. Therefore, even after the stocker reaches the feed position, the bobbin still wants to move beyond the cradle in the release position in the direction of movement of the stocker. However, when the stocker reaches the supply position, the restricting portion is in a released state, and therefore the movement of the bobbin cannot be restricted. Therefore, the bobbin stored in the stocker may move beyond the cradle. In this case, the bobbin cannot be supplied to the cradle appropriately. According to the present invention, since the second restricting portion is provided, when the stocker reaches the supply position, it is possible to suppress the bobbin from moving beyond the cradle in the release position due to inertial force. This makes it possible to more reliably supply the bobbin from the stocker to the cradle.

In the winding device of the present invention, it is preferable that a front end support portion for supporting the bobbin from below is provided at a front end portion of the stocker close to the cradle in the release position, and the front end support portion can The bobbin holder is in a restricted posture that prevents the bobbin from falling off the stocker, and is rotatable about a second rotation axis along the axial direction of the bobbin holder. The stocker further has a biasing member, which biases the bobbin holder. The front end support portion is urged to assume the restricted posture, and when the stocker moves from the supply position to the standby position, the front end support portion is supported by the barrel supported by the cradle in the release position. The tube is pushed to resist the biasing force by the biasing member and rotate around the second rotation axis to avoid the bobbin.

In the present invention, since the front end support portion is provided, it is possible to prevent the bobbin stored in the stocker from falling off the stocker. On the other hand, when the stocker returns to the standby position after the bobbin is supplied from the stocker to the cradle, the front end support portion that prevents the bobbin from falling off may get hooked on the bobbin supported by the cradle, thereby hindering the storage. movement of the feeder. According to the present invention, when the stocker returns from the supply position to the standby position, the front end support portion is rotated so as to avoid the bobbin supported by the cradle. Therefore, it is possible to prevent the front end support portion from being hooked on the bobbin supported by the cradle, thereby preventing the stocker from moving to the standby position. Therefore, the stocker can be smoothly returned to the standby position after supplying the bobbin to the cradle, and the subsequent yarn winding operation can be quickly performed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(The overall composition of the false twisting machine 1) FIG. 1 is a side view showing the schematic structure of the false twisting machine 1 according to this embodiment. Hereinafter, the direction perpendicular to the paper surface in FIG. 1 is referred to as the body length direction, and the left-right direction on the paper surface is referred to as the body width direction. Let the direction orthogonal to both the body length direction and the body width direction be the vertical direction where gravity acts. In the following, the above directional terms will be used appropriately for explanation.

The false twisting machine 1 is configured to perform false twisting on a yarn Y made of a synthetic fiber such as nylon (polyamide-based fiber). The false twisting machine 1 includes: a yarn supply part 2 for supplying the yarn Y; a processing part 3 for performing false twisting on the yarn Y supplied from the yarn supply part 2; and a winding part 4 for processing the yarn Y processed by the processing part 3. The yarn Y is wound around the bobbin Bw. Each component of the yarn supply part 2, the processing part 3, and the winding part 4 is aligned with the running surface of the yarn in which a yarn passage from the yarn supply part 2 through the processing part 3 to the winding part 4 is arranged (Fig. 1 There are multiple planes arranged orthogonally along the length of the machine body.

(Wire supply section 2) The yarn supply part 2 has a creel 7 holding a plurality of yarn supply packages Ps, and supplies a plurality of yarns Y to the processing part 3. The processing section 3 is configured to include a first yarn supply roller 11, a twist-stopping yarn guide 12, a first heating device 13, a cooling device 14, a false twisting device 15, and a second yarn supply roller 11 in order from the upstream side in the yarn traveling direction. The wire roller 16, the interlacing device 17, the third wire supply roller 18, the second heating device 19, and the fourth wire supply roller 20. The winding unit 4 uses the winding device 21 to wind the yarn Y that has been falsely twisted by the processing unit 3 onto the bobbin Bw to form a winding package Pw.

Furthermore, the false twisting machine 1 has a main body 8 and a winding table 9 arranged at intervals in the body width direction. The main body 8 and the winding table 9 extend to approximately the same length in the longitudinal direction of the body and are arranged to face each other. The upper part of the main body 8 and the upper part of the winding table 9 are connected by a support frame 10 . Each device constituting the processing unit 3 is mainly installed on the main body 8 and the support frame 10 . The main body 8, the winding table 9 and the support frame 10 form a working space 22 for the operator to perform operations such as thread hanging on each device. The wire passage is formed so that the wire Y mainly travels around the work space 22 .

The false twisting machine 1 has a unit unit called a span including a pair of main bodies 8 and a winding table 9 arranged to face each other. Each device is arranged in one span so as to simultaneously perform false twist processing on a plurality of yarns Y traveling in a state aligned in the longitudinal direction of the machine body. As an example, a total of 16 winding devices 21 in four layers and four rows are provided on the winding table 9 included in one span. Furthermore, the false twisting machine 1 is configured such that the span is symmetrically arranged on the left and right sides of the paper with the center line C of the main body 8 in the machine width direction as the symmetry axis (the main body 8 is shared by the left and right spans), and the span is symmetrically arranged along the machine body length. There are multiple ones arranged in the direction.

(Structure of processing department) Next, each component of the processing unit 3 will be described. The first yarn supply roller 11 is used to transport the yarn Y supplied from the yarn supply unit 2 to the first heating device 13 . The first yarn supply roller 11 is arranged above the winding table 9 (see FIG. 1 ). The first yarn supply rollers 11 are arranged in one row in the longitudinal direction of the machine body.

The twist-stopping guide 12 prevents the twist applied to the yarn Y by the false twisting device 15 described below from propagating upstream of the twist-stopping guide 12 in the yarn traveling direction. The twist-stop yarn guide 12 is disposed on the downstream side of the first yarn supply roller 11 in the yarn traveling direction and on the upstream side of the first heating device 13 in the yarn traveling direction. The twist-stopping yarn guides 12 are provided individually for each of the plurality of yarns Y supplied from the yarn supply unit 2, for example, and are arranged in one row in the longitudinal direction of the body.

The first heating device 13 is used to heat the yarn Y conveyed from the first yarn supply roller 11 and is provided in the support frame 10 (see FIG. 1 ). A plurality of first heating devices 13 are provided for the plurality of yarns Y supplied from the yarn supply unit 2, and are arranged in one row in the longitudinal direction of the body.

The cooling device 14 is used to cool the yarn Y heated by the first heating device 13 . The cooling device 14 is disposed downstream of the first heating device 13 in the yarn traveling direction and upstream of the false twisting device 15 in the yarn traveling direction. A plurality of cooling devices 14 are provided for the plurality of yarns Y supplied from the yarn supply unit 2, and are arranged in one row in the longitudinal direction of the body.

The false twisting device 15 is a device for twisting the yarn Y. The false twisting device 15 is disposed immediately downstream of the cooling device 14 in the yarn traveling direction. A plurality of false twisting devices 15 are arranged in the length direction of the machine body. For example, 16 false twisting devices 15 are provided in each span.

The second yarn supply roller 16 is a roller that conveys the yarn Y twisted by the false twisting device 15 toward the interlacing device 17 . The second yarn supply roller 16 is disposed in the main body 8 on the downstream side of the false twisting device 15 in the yarn traveling direction. The conveyance speed of the yarn Y by the second yarn supply roller 16 is faster than the conveyance speed of the yarn Y by the first yarn supply roller 11 . Therefore, the yarn Y is stretched between the first yarn supply roller 11 and the second yarn supply roller 16 .

The interlacing device 17 is a device that applies interlacing by spraying air on the yarn Y. The interlacing device 17 is arranged below the second yarn supply roller 16 in the main body 8 .

The third yarn supply roller 18 is a roller that conveys the yarn Y entangled by the entanglement device 17 toward the second heating device 19 . The third yarn supply roller 18 is arranged below the interlacing device 17 in the main body 8 . The conveyance speed of the yarn Y by the third yarn supply roller 18 is slower than the conveyance speed of the yarn Y by the second yarn supply roller 16 . Therefore, the yarn Y is relaxed between the second yarn supply roller 16 and the third yarn supply roller 18 .

The second heating device 19 is a device for heating the yarn Y conveyed from the third yarn supply roller 18 . The second heating device 19 is arranged below the third yarn supply roller 18 in the main body 8 . The second heating devices 19 extend in the up and down direction, and are provided one at each span.

The fourth yarn supply roller 20 is a roller that conveys the yarn Y heat-treated by the second heating device 19 toward the winding device 21 . The fourth yarn supply roller 20 is arranged at the lower part of the winding table 9 . The conveyance speed of the yarn Y by the fourth yarn supply roller 20 is slower than the conveyance speed of the yarn Y by the third yarn supply roller 18 . Therefore, the yarn Y is relaxed between the third yarn supply roller 18 and the fourth yarn supply roller 20 .

In the processing section 3 configured as above, the yarn Y drawn between the first yarn supply roller 11 and the second yarn supply roller 16 is twisted by the false twisting device 15 . The twist formed by the false twist device 15 propagates to the twist-stopping yarn guide 12 but does not propagate to the upstream side of the twist-stopping yarn guide 12 in the yarn traveling direction. The stretched and twisted yarn Y is heated and heat-set by the first heating device 13 and then cooled by the cooling device 14 . The yarn Y is untwisted downstream of the false twisting device 15, but the state in which each filament is falsely twisted into a corrugated shape is maintained by the heat setting. The yarn Y falsely twisted by the false twisting device 15 is relaxed between the second yarn supply roller 16 and the third yarn supply roller 18 , is entangled by the interlacing device 17 , and is guided to the downstream side in the yarn traveling direction. . Furthermore, the yarn Y is relaxed between the third yarn supply roller 18 and the fourth yarn supply roller 20 and is heat-set by the second heating device 19 . Finally, the yarn Y fed from the fourth yarn supply roller 20 is wound by the winding device 21 to form a winding package Pw.

(Configuration of winding section 4) The winding part 4 has a plurality of winding devices 21 . The winding device 21 is a device for winding the yarn Y fed from the fourth yarn supply roller 20 onto the bobbin Bw to form a winding package Pw (the package of the present invention). The bobbin Bw is, for example, a cylindrical member.

As shown in FIG. 2 , the winding device 21 includes a pair of cradle arms 30 (the cradle of the present invention), a contact roller 40 , a package storage part 50 , a stocker 60 and a moving mechanism 80 . FIG. 2 shows a state in the middle of forming the winding package Pw by the winding device 21.

The pair of cradle arms 30 are arranged facing each other in the longitudinal direction of the body. The pair of cradle arms 30 can each rotatably support the bobbin holder 70 . The pair of cradle arms 30 is configured to hold the bobbin Bw through the bobbin holder 70 . The cradle arm 30 forms the winding package Pw by winding the wire around the bobbin Bw held by the bobbin holder 70 . In addition, by opening the pair of cradle arms 30 in the longitudinal direction of the machine body, the winding package Pw (or the bobbin Bw) can be released from the grip of the bobbin holder 70 . The pair of cradle arms 30 can move between the winding position and the release position by rotating about a swing shaft 31 extending along the axial direction of the bobbin holder 70 , that is, the body length direction. As shown in FIG. 2 , the winding position is a position where the yarn Y is wound around the bobbin Bw mounted on the bobbin holder 70 to form the winding package Pw. The cradle arm 30 is configured to move the center x1 of the winding package Pw from the other side to one side in the machine body width direction as the package diameter of the winding package Pw supported by the cradle arm 30 becomes larger. In other words, as the package diameter of the winding package Pw being wound increases, the winding position of the cradle arm 30 moves from the other side to one side in the body width direction. As shown in FIG. 3 , the release position is the position of the cradle arm 30 when the grip of the winding package Pw by the bobbin holder 70 is released, and is a position in which the released winding package Pw can be moved to the package storage part 50 Send location. In addition, the center x1 of the winding package Pw supported by the cradle arm 30 substantially coincides with the axis center of the bobbin holder 70 .

The contact roller 40 is configured to be rotationally driven in a certain direction while in contact with the outer peripheral surface of the bobbin Bw or the winding package Pw, thereby rotating the bobbin Bw and winding the yarn Y. This touch roller 40 is of a so-called line drive type connected to a drive shaft common to each winding device 21, that is, common to a plurality of spindles, and is driven by a motor (not shown). As shown in FIG. 3 , the contact roller 40 is arranged on the other side with a vertical plane F passing through the axis center of the bobbin holder 70 supported by the cradle arm 30 in the release position as a boundary. In this embodiment, the vertical plane F is a plane parallel to the vertical direction and the longitudinal direction of the body. In this embodiment, the other side with the vertical plane F as the boundary refers to the other side in the body width direction than the vertical plane F (the right side of the paper in FIG. 3 ). As shown in FIG. 3 , the contact roller 40 is arranged at a position lower than the stocker 60 in the vertical direction.

The package storage part 50 stores the winding package Pw released from the cradle arm 30 in the release position. In this embodiment, the package storage unit 50 can store up to two winding packages Pw. As shown in FIG. 3 , the package storage portion 50 is arranged on one side with the vertical plane F as a boundary. In this embodiment, the side bounded by the vertical plane F refers to the side closer to the body width direction than the vertical plane F (the left side of the paper in FIG. 3 ).

As shown in FIG. 2 , the package storage unit 50 has two rails 53 arranged to face each other in the longitudinal direction of the machine body. In FIG. 2 , only the rail 53 is shown as being arranged closer to the paper surface than the winding package Pw stored in the package storage part 50 in the longitudinal direction of the body. However, it is actually located farther in the longitudinal direction of the body than the winding package Pw stored in the package storage part 50 A rail 53 is also arranged on the back side of the winding package Pw of the package storage unit 50 in the paper. The distance between the two rails 53 in the length direction of the machine body is slightly narrower than the width of the bobbin Bw in the length direction of the machine body, and is wider than the width of the winding package Pw formed by winding the yarn Y on the bobbin Bw in the length direction of the machine body. big. The wound package Pw conveyed to the package storage unit 50 is supported from below by the upper surfaces 51 of the two rails 53 . More specifically, both end portions of the bobbin Bw on which the winding package Pw is formed are supported from below by the upper surfaces 51 of the two rails 53 .

As shown in FIG. 3 , the package storage section 50 is oriented in a direction from the vertical plane F to one side, that is, from the other side in the machine body width direction (the right side of the paper of FIG. 3 ) to one side (the left side of the paper of FIG. 3 ). Tilt downward. The rail 53 of the package storage part 50 is also inclined downward from the other side in the machine body width direction toward one side. Therefore, the winding package Pw released from the cradle arm 30 rolls from the other side in the body width direction to one side along the upper surface 51 of the downwardly inclined rail 53 . In addition, a member (not shown) for preventing the winding package Pw from further rolling to one side in the body width direction is formed on one end of the package storage portion 50 in the body width direction.

In addition to the fully wound package Pw, the package storage portion 50 stores the yarn Y that is in the middle of winding when the yarn Y is broken while the winding device 21 is winding it. The winding package Pw.

The stocker 60 stores the bobbin Bw for supply to the cradle arm 30 . In this embodiment, the stocker 60 can store up to four bobbins Bw. The bobbin Bw stored in the stocker 60 is an empty bobbin Bw in which the yarn Y is not wound. As shown in FIG. 2 , the stocker 60 extends so that the front end portion on one side in the body width direction is located lower than the rear end portion on the other side. Hereinafter, the direction in which the stocker 60 extends is referred to as the extending direction (see FIG. 5 ). As shown in FIG. 2 , the stocker 60 is arranged at a position higher than the package storage portion 50 and the contact roller 40 in the vertical direction. The detailed structure of the stocker 60 will be described later.

The moving mechanism 80 is used to linearly move the stocker 60 between the standby position and the supply position. The standby position is a position where the stocker 60 is put on standby when the bobbin Bw is not being supplied from the stocker 60 to the cradle arm 30 (see FIGS. 2 and 3 ). Specifically, the standby position is when the yarn Y is wound on the bobbin Bw supported by the cradle arm 30 in the forward direction, or when the winding package Pw is released from the cradle arm 30 in the release position and the package storage portion is forwarded. When 50 is conveying, let the stocker 60 stand in the standby position. The stocker 60 in the standby position can avoid contact with the bobbin Bw or the winding package Pw supported by the cradle arm 30 . As shown in FIG. 3 , the stocker 60 in the standby position is arranged on the other side with the vertical plane F as a boundary. The supply position is a storage position for supplying the bobbin Bw to the bobbin holder 70 supported by the cradle arm 30 in the release position and in a state where the bobbin Bw on which the winding package Pw is formed is removed. The position of the feeder 60 (refer to Figure 4). As shown in FIG. 4 , when the stocker 60 is in the supply position, the axis center of the bobbin Bw located on the farthest side in the machine width direction among the plurality of bobbins Bw stored in the stocker 60 is aligned with the axis center of the bobbin Bw. The axes of the bobbin holder 70 supported by the cradle arm 30 in the released position are aligned.

The moving mechanism 80 is, for example, an actuator connected to the stocker 60, and is driven by the actuator to linearly move the stocker 60 between the standby position and the supply position. In this embodiment, the stocker 60 is installed below the moving mechanism 80 .

(Structure of the stocker 60) Next, the detailed structure of the stocker 60 will be described below with reference to FIGS. 2 to 7 . The stocker 60 includes a support surface 61, a restricting portion 62, a stopper 63, a second restricting portion 64, a front end support portion 65, and a rotating shaft 66 (corresponding to the first rotating shaft and the second rotating shaft in the present invention).

The support surface 61 supports the plurality of bobbins Bw stored in the stocker 60 from below. As shown in FIG. 2 , the support surface 61 is inclined such that one end in the body width direction is located lower than the other end in the body width direction. In other words, the supporting surface 61 extends along the extending direction of the stocker 60 . Therefore, the bobbin Bw stored in the stocker 60 moves from the other side in the body width direction toward one side along the inclination of the support surface 61 .

As shown in FIG. 2 , the rotation axis 66 is a rotation axis along the axial direction of the bobbin holder 70 , that is, the longitudinal direction of the body. The rotating shaft 66 is formed at a lower end portion of the stocker 60 on one side in the body width direction.

The restricting portion 62 is a member for preventing the bobbin Bw stored in the stocker 60 from falling off the stocker 60 . The restricting parts 62 are arranged to face each other in the longitudinal direction of the body. The spacing between the oppositely arranged restricting portions 62 in the longitudinal direction of the body is greater than the width of the bobbin Bw in the longitudinal direction of the body. The restriction part 62 is configured to be able to switch between a restriction state (the state of FIGS. 2 , 3 and 6 ) in which the bobbin Bw stored in the stocker 60 is prevented from falling off the stocker 60 and a release state in which the restriction state is released ( FIG. 4 and the status in Figure 7). As the stocker 60 moves from the standby position to the supply position, the restriction part 62 rotates in the first direction D1 (see the solid arrow in FIG. 6 ) about the rotation shaft 66 to switch from the restriction state to the release state. The first direction D1 is the clockwise direction in FIG. 6 . As the stocker 60 moves from the supply position to the standby position, the restriction part 62 rotates in the second direction opposite to the first direction D1 about the rotation shaft 66 to switch from the release state to the restriction state. The second direction is the counterclockwise direction in FIG. 6 . The state switching of the restriction unit 62 will be described in detail later. As shown in FIG. 5 , two restricting portions 62 are arranged to face each other in the longitudinal direction of the body. The distance between the two restricting parts 62 in the longitudinal direction of the body is slightly larger than the width of the bobbin Bw in the longitudinal direction of the body.

As shown in FIG. 5 , the restricting portion 62 includes a claw portion 62a, an arm portion 62b, and a contact portion 62c. The claw portion 62a restricts the movement of the bobbin Bw stored in the stocker 60 from the other side to one side in the machine body width direction along the support surface 61, thereby preventing the bobbin Bw from falling off the stocker 60. The claw portion 62a is connected to the rotation shaft 66 through the arm portion 62b. The claw portion 62a has a plate-like shape.

As shown in FIGS. 2 and 5 , the claw portion 62 a extends toward one side in the body width direction and downward from the front end portion of the arm portion 62 b opposite to the side connected to the rotation shaft 66 . As shown in FIGS. 2 and 6 , when the restricting portion 62 is in the restricting state, the distance between the claw portion 62 a and the bobbin Bw located on the farthest side in the machine body width direction among the plurality of bobbins Bw stored in the stocker 60 One side in the width direction of the machine body is in contact with the upper part. Thereby, the claw part 62a can restrict the movement of the bobbin Bw along the inclined support surface 61. In addition, as shown in FIGS. 4 and 7 , when the restricting portion 62 is in the released state, the claw portion 62 a avoids contact with the bobbin Bw stored in the stocker 60 . Thereby, the movement restriction of the bobbin Bw by the claw part 62a is released.

The arm portion 62b is connected to the rotation shaft 66 and the claw portion 62a. The arm portion 62b can restrict the movement of the bobbin Bw located on the farthest side in the machine body width direction among the plurality of bobbins Bw stored in the stocker 60 in the machine body length direction. Specifically, the arm portion 62b of the restricting portion 62 on the front side of the paper surface in the machine body longitudinal direction restricts the bobbin Bw stored in the stocker 60 from moving toward the paper plane front side in the machine body longitudinal direction. In addition, the arm portion 62b of the restricting portion 62 on the back side of the paper in the machine body longitudinal direction restricts the movement of the bobbin Bw stored in the stocker 60 toward the paper back side in the machine body length direction.

The abutment portion 62c is a portion capable of abutting against the bobbin holder 70 supported by the cradle arm 30 in the release position. As shown in FIG. 5 , the contact portion 62 c is formed on one side of the arm portion 62 b in the body width direction. As the stocker 60 moves from the standby position to the supply position, the abutment portion 62c abuts the bobbin holder 70 supported by the cradle arm 30 in the release position.

The stopper 63 is a portion against which the restricting portion 62 that rotates in the first direction D1 can come into contact. Specifically, the stopper 63 is a portion with which the upper portion of the other side of the arm portion 62b in the body width direction can come into contact (see FIG. 7 ). The stoppers 63 are arranged opposite each other in the length direction of the body. A stopper 63 is formed on the upper part of the stocker 60 . More specifically, when four bobbins Bw are accommodated in the stocker 60, the first to fourth bobbins Bw are provided in order from the bobbin Bw on one side in the machine body width direction. , a stopper 63 is formed on the upper portion of the second bobbin Bw. As shown in FIGS. 4 and 7 , when the stocker 60 reaches the supply position, the restricting portion 62 that rotates in the first direction D1 comes into contact with the stopper 63 , whereby the restricting portion 62 further rotates in the first direction D1 Is limited.

The second restriction part 64 is a member that prevents the bobbin Bw stored in the hopper 60 from flying out beyond the bobbin holder 70 when the hopper 60 reaches the supply position and the restriction part 62 is in the released state. As shown in FIG. 5 , the second restricting portion 64 extends from an upper portion near an end of one side of the stocker 60 in the body width direction toward one side in the body width direction and downward in the vertical direction. In addition, the second restricting portion 64 is an elastic member such as a leaf spring, for example. When the stocker 60 that has completed the delivery of the bobbin Bw to the cradle arm 30 moves from the supply position to the standby position, the second restricting portion 64 may hook the bobbin Bw supported by the cradle arm 30 and hinder the stocking. movement of the device 60. In this regard, the second restricting portion 64 as an elastic member is configured to move upward when the stocker 60 comes into contact with the bobbin Bw supported by the cradle arm 30 as the stocker 60 moves from the supply position to the standby position. It bends when pressed. Thereby, when the stocker 60 moves from the supply position to the standby position, it is possible to suppress the second restricting portion 64 from being hooked on the bobbin Bw supported by the cradle arm 30 . In addition, as shown in FIG. 5 , two second restricting portions 64 are disposed on both sides of the central portion of the stocker 60 and inward of the two restricting portions 62 in the longitudinal direction of the machine body.

The front end support part 65 supports the bobbin Bw located on the farthest side in the machine body width direction among the plurality of bobbins Bw stored in the stocker 60 from below. As shown in FIGS. 2 and 5 , the front end support portion 65 is provided in the lower portion of the stocker 60 close to the front end portion of the cradle arm 30 in the release position. In addition, as shown in FIG. 5 , the front end support portion 65 extends along the body length direction. Furthermore, as shown in FIGS. 6 and 7 , when viewed from the longitudinal direction of the body, a portion on one side of the front end support portion 65 in the width direction of the body is curved into a V-shape. The front end support part 65 is made of a metal plate or resin, for example.

The front end support portion 65 can be in a restricted posture that prevents the bobbin Bw from falling off the stocker 60 . When the front end support portion 65 is in the restricted position, the bobbin Bw is fitted into the V-shaped portion of the front end support portion 65 to prevent the bobbin Bw from falling off the stocker 60 (see FIGS. 6 and 7 ). In addition, the bobbin Bw can be accurately positioned by fitting the bobbin Bw into the V-shaped portion of the posture-restricting tip support portion 65 . Thereby, when the stocker 60 reaches the supply position, the bobbin Bw can be accurately transferred to the bobbin holder 70 supported by the cradle arm 30 in the release position. In addition, the front end support part 65 is rotatable about the rotation shaft 66. In addition, in this embodiment, the rotation shaft 66 is shared between the restricting portion 62 and the front end support portion 65 .

Furthermore, the stocker 60 includes a force applying member 67 . The urging member 67 is a member that urges the distal end support 65 which is rotatable about the rotation shaft 66 so as to assume a restricted posture. The urging member 67 is, for example, a spring member. In addition, in this embodiment, the urging member 67 also has a function of urging the restricting part 62 that is rotatable about the rotation shaft 66 to bring it into a restricted state.

(Supply operation of bobbin Bw from stocker 60 to cradle arm 30) Next, when the bobbin Bw is supplied to the cradle arm 30, the operation of the stocker 60 that moves between the standby position and the supply position and the respective components accompanying this movement will be described below.

As described above, while the winding device 21 winds the yarn Y and when the winding package Pw is released from the cradle arm 30 in the release position and transported to the package storage part 50, the stocker 60 is in the Standby position (see Figure 2 and Figure 3). When the stocker 60 is in the standby position, the restriction part 62 is in the restriction state, and the front end support part 65 is in the restriction posture (see FIGS. 2 and 3 ).

When the winding package Pw is released from the cradle arm 30 in the release position and transported to the package storage part 50, the moving mechanism 80 linearly moves the stocker 60 from the standby position toward the supply position. In this embodiment, the stocker 60 in the standby position moves linearly toward one side in the machine body width direction and in a downward oblique direction (a direction diagonally downward to the left of the paper in FIG. 3 ). In this embodiment, the extending direction of the stocker 60 is substantially consistent with the direction in which the stocker 60 moves. In addition, FIG. 6 shows the stocker 60 on the way from the standby position to the supply position.

While the stocker 60 is moving from the standby position to the supply position, the contact portion 62c comes into contact with the bobbin holder 70 supported by the cradle arm 30 in the release position. More specifically, in FIGS. 3 and 4 , etc., the contact portion 62 c of the restricting portion 62 disposed on the back side of the paper in the longitudinal direction of the body contacts the bobbin holder 70 disposed on the back side of the paper in the longitudinal direction of the body, and is disposed. The contact portion 62c of the restricting portion 62 on the front side of the paper in the machine body longitudinal direction is in contact with the bobbin holder 70 arranged on the front side of the paper in the machine body length direction. As the stocker 60 moves further toward the supply position from the state in which the abutment portion 62c is in contact with the bobbin holder 70, the abutment portion 62c is pressed by the bobbin holder 70. Thereby, the restriction part 62 of the stocker 60 rotates in the 1st direction D1 (refer FIG. 6) about the rotation shaft 66, and switches from a restriction state to a release state. Then, when the stocker 60 reaches the supply position, the restricting portion 62 enters the released state (see FIGS. 4 and 7 ). In addition, in FIGS. 6 and 7 , for convenience of explanation, the cradle arm 30 and the bobbin holder 70 on the front side of the paper in the longitudinal direction of the body are omitted.

As shown in FIG. 7 , when the stocker 60 reaches the supply position, the restricting portion 62 comes into contact with the stopper 63 . Thereby, the restriction part 62 is restricted from further rotating in the 1st direction D1. In other words, the bobbin holder 70 supported by the cradle arm 30 in the release position and the stopper 63 sandwich the restricting part 62, whereby the rotation of the restricting part 62 is restricted, and the stocker 60 is restricted from further moving beyond the supply position. .

When the stocker 60 reaches the supply position, the bobbin Bw supported from below by the front end support portion 65 among the plurality of bobbins Bw stored in the stocker 60 is attached to the barrel supported by the cradle arm 30 in the release position. Tube holder 70. To explain in more detail, when the stocker 60 reaches the supply position, the restriction part 62 is in the released state, so the restriction by the arm part 62b on both sides of the bobbin Bw supported from below by the front end support part 65 is released. (Refer to Figure 7). In this state, the bobbin holder 70 closes the hollow portion of the cylindrical bobbin Bw from both sides of the bobbin Bw in the longitudinal direction of the machine body toward the inside in the longitudinal direction of the machine body, and the bobbin holder 70 clamps the bobbin Bw. Bw.

When the bobbin Bw is supported by the cradle arm 30, the moving mechanism 80 linearly moves the stocker 60 from the supply position toward the standby position. The stocker 60 moves away from the cradle arm 30 in the release position toward the other side in the machine body width direction as it moves from the supply position to the standby position. Thereby, the restriction portion 62 in which the contact portion 62c is in contact with the bobbin holder 70 supported by the cradle arm 30 in the release position rotates about the rotation axis 66 in the second direction opposite to the first direction D1 and from The released state switches to the restricted state. Then, the contact between the contact portion 62c and the bobbin holder 70 is released, and the restriction portion 62 returns to the restriction state by the urging force of the urging member 67.

Furthermore, when the stocker 60 moves from the supply position to the standby position, the V-shaped portion of the front end support portion 65 is pressed by the bobbin Bw supported by the cradle arm 30 in the release position. Thereby, the front-end support part 65 resists the urging|biasing force by the urging|biasing member 67, and rotates around the rotation axis 66 so that it may avoid the bobbin Bw. In other words, the front end support portion 65 counters the urging force by the urging member 67 and rotates about the rotation shaft 66 so that the front end portion is lower than the base end portion connected to the rotation shaft 66 . Then, when the stocker 60 further moves toward the standby position so that the tip support portion 65 and the bobbin Bw become out of contact, the tip support portion 65 returns to the restricted posture by the biasing force of the biasing member 67 . In addition, while the stocker 60 is returning from the supply position to the standby position, the bobbin Bw remaining in the stocker 60 moves along the inclined support surface 61 . Furthermore, the bobbin Bw located on the farthest side in the machine body width direction among the plurality of bobbins Bw remaining in the stocker 60 is supported from below by the front end support portion 65 that returns to the restricted posture.

Through the above operation, the operation of supplying the bobbin Bw from the stocker 60 to the cradle arm 30 is completed.

(Effect) The winding device 21 of this embodiment includes a package storage part 50 arranged on one side with the vertical plane F as a boundary, a stocker 60 arranged on the other side with the vertical plane F as a boundary, and a package storage part 50 arranged on one side with the vertical plane F as a boundary. The moving mechanism 80 moves the stocker 60 between the standby position and the supply position. The moving mechanism 80 linearly moves the stocker 60 between the standby position and the supply position. Accordingly, the stocker 60 will not pass through a position above both the standby position and the supply position while moving from the standby position to the supply position, and there is no need to secure a separate space above the winding device 21 . However, even when the stocker 60 is moved linearly, for example, when the stocker 60 is arranged above the package storage part 50 as in the above-mentioned Patent Document 2, the position of the stocker 60 will still become high. , there is a limit to reducing the height dimension of the winding device 21 . The reason for this is that the winding package Pw released from the cradle arm 30 is conveyed to the package storage part 50 through the lower part of the stocker 60, so the distance between the stocker 60 and the package storage part 50 must be increased. It is large enough for the winding package Pw to pass. In this regard, in this embodiment, the stocker 60 is arranged on the opposite side of the package storage portion 50 with the vertical plane F as a boundary. Therefore, the stocker 60 can be disposed at a lower position and the stocker 60 cannot pass above both the standby position and the supply position. Therefore, the height of the winding device 21 can be effectively suppressed.

In the winding device 21 of this embodiment, the stocker 60 is provided with a restriction portion 62 switchable between a restriction state and a release state. The restriction part 62 is in a released state when the stocker 60 reaches the supply position. Accordingly, before the stocker 60 reaches the supply position, the bobbin Bw can be prevented from falling off the stocker 60 by the regulating portion 62 in the restricted state. Furthermore, when the stocker 60 reaches the supply position, the restricting portion 62 is in the released state, so the supply of the bobbin Bw from the stocker 60 to the cradle arm 30 is not hindered by the restricting portion 62 . Thereby, the bobbin Bw can be reliably stored in the stocker 60 and the bobbin Bw can be appropriately supplied from the stocker 60 to the cradle arm 30 .

In the winding device 21 of this embodiment, the restricting portion 62 has a contact portion 62c capable of contacting the bobbin holder 70 supported by the cradle arm 30 in the release position. The restriction portion 62 is configured such that as the stocker 60 moves from the standby position to the supply position, the contact portion 62c is pressed by the bobbin holder 70 and thereby rotates in the first direction D1 about the rotation axis 66 to move from the restriction state. Switch to release state. In addition, the restriction portion 62 is configured such that as the stocker 60 moves from the supply position to the standby position, the contact between the contact portion 62 c and the bobbin holder 70 is released, thereby moving the rotation axis 66 as the center in the first direction D1 The second direction rotation in the opposite direction switches from the released state to the restricted state. Accordingly, the release state and the restriction state of the restriction portion 62 can be switched depending on whether the contact portion 62c is brought into contact with the bobbin holder 70 as the stocker 60 moves. Therefore, a drive source for switching the state of the restriction unit 62 is not necessary.

In the winding device 21 of this embodiment, the stocker 60 has a stopper 63 capable of contacting the restricting portion 62 that rotates in the first direction D1. When the stocker 60 reaches the supply position, the restriction portion 62 that rotates in the first direction D1 because the contact portion 62c is pressed by the bobbin holder 70 is restricted from further rotating in the first direction D1 by contacting the stopper 63. Rotate in direction D1. Accordingly, the contact portion 62c of the restricting portion 62 is restricted from being further pushed by the bobbin holder 70, that is, further movement of the stocker 60 is restricted. This can prevent the stocker 60 from moving further beyond the supply position, and can appropriately supply the bobbin Bw from the stocker 60 to the cradle arm 30 .

In addition, in the winding device 21 of this embodiment, the second restricting part 64 is provided in the stocker 60. When the stocker 60 reaches the supply position and the restricting part 62 is in the released state, the second restricting part 64 restricts the storage. The bobbin Bw in the stocker 60 exceeds the bobbin holder 70 and flies out. When the stocker 60 moves from the standby position to the supply position, inertia force acts on the bobbin Bw. Therefore, even after the stocker 60 reaches the supply position, the bobbin Bw still wants to move beyond the cradle arm 30 in the release position in the direction in which the stocker 60 moves. However, when the stocker 60 reaches the supply position, the restricting portion 62 is in the released state, and therefore the movement of the bobbin Bw cannot be restricted. Therefore, the bobbin Bw stored in the stocker 60 may move beyond the cradle arm 30 . In this case, the bobbin Bw cannot be supplied appropriately to the cradle arm 30 . According to this embodiment, since the second restricting portion 64 is provided, when the stocker 60 reaches the supply position, it is possible to suppress the bobbin Bw from moving beyond the cradle arm 30 in the release position due to inertial force. Thereby, the bobbin Bw can be supplied from the stocker 60 to the cradle arm 30 more reliably.

In the winding device 21 of this embodiment, a front end support portion 65 for supporting the bobbin Bw from below is provided in the front end portion of the stocker 60 close to the cradle arm 30 in the release position. The front end support portion 65 can be in a restricted posture that prevents the bobbin Bw from falling off the stocker 60, and can rotate about the rotation shaft 66. Furthermore, the stocker 60 further includes a biasing member 67 that biases the front end support portion 65 to assume a restricted posture. When the stocker 60 moves from the supply position to the standby position, the front end support portion 65 is pushed by the bobbin Bw supported by the cradle arm 30 in the release position, thereby rotating against the biasing force of the biasing member 67 The shaft 66 rotates around the bobbin so as to avoid the bobbin. In this embodiment, since the front end support portion 65 is provided, the bobbin Bw stored in the stocker 60 can be prevented from falling off the stocker 60 . On the other hand, when the stocker 60 returns to the standby position after the supply of the bobbin Bw from the stocker 60 to the cradle arm 30 is completed, the front end support 65 to prevent the bobbin Bw from falling off and the end support 65 supported by the cradle arm 30 There is a possibility that the bobbin Bw gets caught and hinders the movement of the stocker 60 . According to this embodiment, when the stocker 60 returns from the supply position to the standby position, the front end support portion 65 rotates so as to avoid the bobbin Bw supported by the cradle arm 30 . Therefore, it is possible to prevent the tip support portion 65 from being hooked on the bobbin Bw supported by the cradle arm 30 and preventing the stocker 60 from moving to the standby position. Therefore, the stocker 60 can be smoothly returned to the standby position after supplying the bobbin Bw to the cradle arm 30, and the subsequent winding operation of the yarn Y can be quickly performed.

(Modification) Hereinafter, a modification example in which changes are made to the above-described embodiment will be described. However, elements having the same configuration as those in the above-mentioned embodiment are denoted by the same reference numerals, and description thereof is appropriately omitted.

In the above embodiment, the restriction portion 62 is configured such that as the stocker 60 moves from the standby position to the supply position, the contact portion 62c is pressed by the bobbin holder 70, thereby switching from the restriction state to the release state. However, the restriction part 62 capable of switching between the restriction state and the release state is not limited to the above-mentioned configuration. For example, the restriction part 62 may be switchable between a restriction state and a release state by an electric motor.

Furthermore, in the above-described embodiment, the restricting portion 62 is capable of switching between the restricted state and the released state by rotating about the rotation shaft 66 . However, the restriction part 62 is not limited to the structure which rotates about the rotation axis 66. For example, the restriction part 62 may be configured to be switchable between the restriction state and the release state by sliding in a direction intersecting the extending direction of the stocker 60 .

In the above-described embodiment, the stocker 60 in the standby position is tilted toward one side in the direction that is substantially consistent with the extending direction of the stocker 60, that is, in the machine body width direction (the left diagonal direction on the paper in FIG. 3). downward) moves in a straight line. However, the stocker 60 in the standby position may also move linearly in an upward oblique direction toward one side in the machine body width direction (for example, an upward left diagonal direction in FIG. 3 ) or in a horizontal direction. In this case, the stocker 60 is provided with a push-out mechanism for pushing the bobbin Bw stored in the stocker 60 from the rear end toward the front end of the stocker 60 in the extending direction. In addition, the extending direction of the stocker 60 and the direction in which the stocker 60 moves linearly may not be substantially consistent.

In the above embodiment, one rotation axis 66 corresponds to both the first rotation axis and the second rotation axis of the present invention. However, the first rotation axis that is the rotation center of the restriction portion 62 and the second rotation axis that is the rotation center of the front end support portion 65 may be provided separately.

In the above embodiment, the stocker 60 has the restriction part 62 switchable between the restriction state and the release state. However, the stocker 60 does not need to have the restricting portion 62 . In this case, it is preferable that the stocker 60 is provided with a member for preventing the bobbin Bw from falling off from the stocker 60 in the standby position and from the stocker 60 moving from the standby position to the supply position.

In the above embodiment, the stocker 60 has the second restricting portion 64. When the restricting portion 62 is in the released state, the second restricting portion 64 prevents the bobbin Bw stored in the stocker 60 from flying out beyond the bobbin holder 70. . However, the stocker 60 does not need to have the second restricting portion 64 . In this case, the moving mechanism 80 preferably sets the moving speed of the stocker 60 from the standby position to the supply position to a predetermined speed or less. The predetermined speed is a speed that can suppress the bobbin Bw from flying out from the stocker 60 that has reached the supply position, overtaking the bobbin holder 70 . Thereby, when the stocker 60 moves from the standby position to the supply position, the inertial force acting on the bobbin Bw can be suppressed, and the bobbin Bw can be suppressed from falling off the stocker 60 .

In the above-described embodiment, two second restricting portions 64 are provided in portions on both sides of the central portion of the stocker 60 and inward of the two restricting portions 62 in the longitudinal direction of the machine body. However, the number of second restricting parts 64 is not limited to two. For example, one second restriction unit 64 may be arranged, or three or more second restriction units 64 may be arranged.

In the above embodiment, the stocker 60 has the front end support portion 65 . However, the stocker 60 does not need to have the front end support portion 65 . In this case, it is preferable that the stocker 60 is provided with the second restricting portion 64 .

The winding device 21 of the above embodiment is applied to the false twisting machine 1 . However, the winding device 21 of the present invention is not limited to the false twisting machine 1 and may be applied to a winding device of a winder.

In the above embodiment, the cradle arm 30 is configured to be movable between the winding position and the release position. However, the cradle arm 30 may not move between the winding position and the release position. For example, if it is not a wire drive type in which the contact roller 40 is connected to a drive shaft common to multiple spindles, it may also be a fixed cradle arm. Frame arm (refer to Japanese Patent Application Publication No. 2015-40116, etc.). In this case, the winding position and the release position of the cradle arm are the same position.
