Description

Coiling device

Technical Field

The present invention relates to a winding apparatus.

Background

Patent document 1 discloses a false twisting machine including a false twisting device for applying a false twist to a yarn fed from a yarn feeding section, and a winding device for winding the false twisted yarn. The winding device includes a cradle rotatably supporting a set of bobbin holders, and winds a yarn around a bobbin (paper tube of patent document 1) attached to the bobbin holders to form a package.

When a full-wound package is formed in such a winding apparatus, the package is removed from the cradle and a new bobbin is supplied to the cradle. Patent document 2 describes a winding device (doffing device of patent document 2) having a package storage portion (guide rail of patent document 2) for supporting packages removed from a cradle, and a stocker (paper tube stocker of patent document 2) for storing empty bobbins supplied to the cradle in an aligned state.

In the winding device of patent document 2, the stocker is swingably supported by a rotating shaft provided below the stocker via a support bracket. The stocker is located at a standby position (a position shown in fig. 2) above the package storage section when winding the yarn, and is moved to a supply position below the standby position and on the right side of the paper surface (hereinafter, simply referred to as the right side and the left side of the paper surface simply referred to as the left side) of fig. 2 of patent document 2 by swinging around the rotation axis when supplying the bobbin to the cradle.

Patent document 1: japanese patent laid-open publication No. 2011-47074

Patent document 2: japanese patent laid-open No. 9-86799

In the apparatus of patent document 2, as shown in fig. 2, when the stocker is located at the standby position, the support bracket for supporting the stocker is inclined obliquely upward and leftward from the rotation axis. On the other hand, when the stocker is located at the supply position, the support bracket swings clockwise from the state shown in fig. 2, and the support bracket is inclined obliquely upward and rightward from the rotation axis. That is, the support bracket is inclined obliquely upward and leftward from the state of being inclined obliquely upward and leftward, and then is inclined obliquely upward and rightward after being once in the vertical direction during the movement of the stocker from the standby position to the supply position. Then, the stocker connected to the support bracket passes through a position above both the standby position and the supply position in the middle of moving from the standby position to the supply position. Therefore, it is necessary to secure a space above the winding device so as not to interfere with other members during the movement from the standby position to the supply position. However, since such a space is ensured, the substantial height dimension of the winding device becomes large.

Disclosure of Invention

The purpose of the present invention is to suppress the increase in height dimension of a winding device.

The winding device of the present invention is characterized by comprising: a cradle which rotatably supports a bobbin holder and which winds a yarn around a bobbin held by the bobbin holder to form a package, and which releases the package from the holding of the bobbin holder; a package storage unit for storing the package released from the cradle; a stocker for storing the bobbins to be supplied to the cradle; and a moving mechanism that moves the stocker between a standby position and a supply position where the bobbin is supplied to the cradle at a release position where the gripping of the bobbin holder on the package is released, wherein the package storage section is disposed on one side with a vertical plane passing through an axis of the bobbin holder supported by the cradle at the release position as a boundary, the stocker at the standby position is disposed on the other side with the vertical plane as a boundary, and the moving mechanism linearly moves the stocker between the standby position and the supply position.

According to the present invention, the stocker can be moved from the standby position to the supply position by being linearly moved. Therefore, the accumulator does not pass through the position above both the standby position and the supply position in the middle of moving from the standby position to the supply position, and a separate space above the winding device is not required. However, even when the stocker is linearly moved, there is a limit in lowering the height dimension of the winding device because, for example, when the stocker is disposed above the package storage section as in patent document 2, the position of the stocker becomes high. The reason for this is that the package released from the cradle passes under the stocker and is transported to the package storage unit, and therefore, it is necessary to increase the distance between the stocker and the package storage unit to such an extent that the package can pass. In this regard, in the present invention, the stocker is disposed on the opposite side of the package storage section with the vertical surface as a boundary. Therefore, the stocker can be arranged at a low position, and the stocker does not pass through a position above both the standby position and the supply position, so that the height of the winding device can be effectively suppressed.

In the winding device according to the present invention, preferably, a regulating portion is provided at a tip end portion of the cradle in the stocker near the release position, the regulating portion being switchable between a regulating state in which the bobbin stored in the stocker is prevented from coming off the stocker and a release state in which the regulating state is released, and the regulating portion is brought into the release state when the stocker reaches the supply position.

According to the present invention, the bobbin can be prevented from falling off the stocker by the regulating portion in the regulating state before the stocker reaches the supply position. Further, since the regulating portion is released when the stocker reaches the supply position, the supply of the bobbin from the stocker to the cradle is not hindered by the regulating portion. This enables the bobbins to be reliably stored in the stocker, and the bobbins to be appropriately supplied from the stocker to the cradle.

In the winding device according to the present invention, preferably, the stocker includes a 1 st rotation axis along an axial direction of the bobbin holder, the regulating portion includes an abutting portion that can abut against the bobbin holder supported by the cradle in the release position, and the abutting portion is pushed by the bobbin holder as the stocker moves from the standby position to the supply position, whereby the regulating portion is rotated about the 1 st rotation axis in the 1 st direction to switch from the regulating state to the release state, and the abutting portion is released from contact with the bobbin holder as the stocker moves from the supply position to the standby position, whereby the regulating portion is rotated about the 1 st rotation axis in a 2 nd direction opposite to the 1 st direction to switch from the release state to the regulating state.

According to the present invention, the release state and the restriction state of the restriction portion can be switched according to whether or not the abutting portion is in contact with the bobbin holder as the stocker moves. Therefore, a driving source for switching the state of the restriction portion is not required.

In the winding device according to the present invention, it is preferable that the stocker has a stopper which can be abutted against the restricting portion for rotation in the 1 st direction, and when the stocker reaches the supply position, the abutting portion is pressed by the bobbin holder and the restricting portion for rotation in the 1 st direction is restricted from further rotation in the 1 st direction by abutting against the stopper.

According to the present invention, the restricting portion that rotates in the 1 st direction along with the movement of the stocker is restricted from further rotating in the 1 st direction by abutting against the stopper. Therefore, the abutting portion of the regulating portion is regulated in a state of being further pushed by the bobbin holder, that is, in a state of being further moved by the stocker. This can prevent the stocker from further moving beyond the supply position, and can properly supply the bobbins from the stocker to the cradle.

In the winding device according to the present invention, it is preferable that the stocker is provided with a 2 nd regulating portion, and the 2 nd regulating portion suppresses the bobbin stored in the stocker from being thrown out beyond the bobbin holder when the stocker reaches the supply position and the regulating portion is in the released state.

When the stocker moves from the standby position to the supply position, an inertial force acts on the bobbin. Therefore, even after the stocker reaches the supply position, the bobbin is moved over the cradle in the release position in the direction in which the stocker is moved. However, when the stocker reaches the supply position, the regulating portion is in a released state, and therefore, the movement of the bobbin cannot be regulated. Therefore, the bobbin stored in the stocker may move over the cradle. In this case, the supply of the bobbin to the cradle cannot be properly performed. According to the present invention, since the 2 nd regulating portion is provided, when the stocker reaches the supply position, the bobbin can be restrained from moving over the cradle at the release position due to the inertial force. This makes it possible to more reliably supply bobbins from the stocker to the cradle.

In the winding device according to the present invention, it is preferable that a tip end portion of the cradle near the release position in the stocker is provided with a tip end supporting portion for supporting the bobbin from below, the tip end supporting portion is capable of taking a restricting posture for preventing the bobbin from coming off the stocker and is rotatable about a 2 nd rotation axis along an axial direction of the bobbin holder, the stocker further includes a biasing member for biasing the tip end supporting portion to the restricting posture, and the tip end supporting portion is pressed against the bobbin supported by the cradle at the release position when the stocker moves from the supply position to the standby position, thereby being rotatable about the 2 nd rotation axis so as to avoid the bobbin against the biasing force of the biasing member.

In the present invention, since the tip support portion is provided, the bobbin stored in the stocker can be prevented from coming off the stocker. On the other hand, when the stocker is to return to the standby position after the supply of the bobbin from the stocker to the cradle is completed, the tip support portion to prevent the bobbin from coming off may be caught by the bobbin supported by the cradle and interfere with the movement of the stocker. According to the present invention, when the stocker returns from the supply position to the standby position, the front end supporting portion rotates so as to avoid the bobbin supported by the cradle. Therefore, the tip support portion can be prevented from being caught by the bobbin supported by the cradle, and the stocker can be prevented 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 winding operation of the wire can be rapidly performed thereafter.

Detailed Description

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

(integral construction of false twisting machine 1)

Fig. 1 is a side view showing a schematic configuration of a false twist machine 1 according to the present embodiment. Hereinafter, the direction perpendicular to the paper surface in fig. 1 is referred to as the machine body longitudinal direction, and the left-right direction is referred to as the machine body width direction. The direction orthogonal to both the longitudinal direction and the width direction of the machine body is defined as the vertical direction in which gravity acts. Hereinafter, the above directional terms will be appropriately used for explanation.

The false twisting machine 1 is configured to be capable of false twisting a yarn Y made of synthetic fibers such as nylon (polyamide-based fibers). The false twist texturing machine 1 includes: a yarn feeding section 2 for feeding a yarn Y; a processing unit 3 for performing false twisting on the yarn Y fed from the yarn feeding unit 2; and a winding unit 4 for winding the yarn Y processed by the processing unit 3 on a bobbin Bw. The components of the yarn feeding section 2, the processing section 3, and the winding section 4 are arranged in a plurality in the longitudinal direction of the machine body orthogonal to the running surface (the paper surface of fig. 1) of the yarn on which the yarn path from the yarn feeding section 2 to the winding section 4 through the processing section 3 is arranged.

(yarn feeding section 2)

The yarn feeding section 2 has a creel 7 for holding a plurality of yarn feeding packages Ps, and supplies a plurality of yarns Y to the processing section 3. The processing unit 3 is configured such that a 1 st godet 11, a stop yarn guide 12, a 1 st heating device 13, a cooling device 14, a false twisting device 15, a 2 nd godet 16, a interlacing device 17, a 3 rd godet 18, a 2 nd heating device 19, and a 4 th godet 20 are arranged in this order from the upstream side in the yarn advancing direction. The winding unit 4 winds the yarn Y false twisted by the processing unit 3 around the bobbin Bw by the winding device 21 to form a winding package Pw.

The false twist machine 1 further includes a main body 8 and a winding table 9 arranged at intervals in the machine body width direction. The main body 8 and the winding stand 9 are provided so as to extend substantially the same length in the longitudinal direction of the main body, and are disposed so as to face each other. The upper part of the main body 8 and the upper part of the winding stand 9 are connected by a support frame 10. The respective devices constituting the processing section 3 are mainly mounted on the main body 8 and the support frame 10. A work space 22 for an operator to perform a work such as wire hanging on each device is formed by the main body 8, the winding stand 9, and the support frame 10. The yarn channel is formed so that the yarn Y mainly runs around the working space 22.

The false twist machine 1 has a unit cell called a span including a pair of main bodies 8 arranged to face each other and a winding table 9. Each device is disposed in one span so as to be capable of simultaneously performing false twisting on a plurality of yarns Y traveling in a state of being aligned in the machine body longitudinal direction. As an example, a total of 16 winding devices 21 of 4 layers and 4 rows are provided on the winding stand 9 included in one span. The false twist machine 1 is configured such that the span is symmetrically arranged on the left and right sides of the drawing (the main machine body 8 is shared by the left and right spans) with the center line C of the main machine body 8 in the machine body width direction as a symmetry axis, and a plurality of spans are arranged in the machine body length direction.

(construction of processing section)

Next, each constituent element of the processing unit 3 will be described. The 1 st godet 11 is configured to convey the yarn Y fed from the yarn feeding section 2 to the 1 st heating device 13. The 1 st godet 11 is disposed above the winding stage 9 (see fig. 1). The 1 st godet 11 is arranged in 1 row in the longitudinal direction of the machine body.

The anti-twist yarn guide 12 is used to prevent the twist applied to the yarn Y by the false twisting device 15 described later from being propagated to the upstream side of the anti-twist yarn guide 12 in the yarn advancing direction. The anti-twist yarn guide 12 is disposed downstream of the 1 st yarn feeding roller 11 in the yarn traveling direction and upstream of the 1 st heating device 13 in the yarn traveling direction. The yarn-stopping guides 12 are provided independently for each of the plurality of yarns Y fed from the yarn feeding section 2, and are arranged in 1 row in the longitudinal direction of the machine body, for example.

The 1 st heating device 13 is provided in the support frame 10 (see fig. 1) for heating the yarn Y fed from the 1 st godet 11. The 1 st heating device 13 is provided in plural for the plurality of wires Y supplied from the wire supply portion 2, and is arranged in 1 row in the machine body length direction.

The cooling device 14 is used for cooling the yarn Y heated by the 1 st heating device 13. The cooling device 14 is disposed downstream of the 1 st heating device 13 in the yarn traveling direction and upstream of the false twisting device 15 in the yarn traveling direction. The cooling device 14 is provided in plural for the plurality of yarns Y supplied from the yarn supplying section 2, and is arranged in 1 row in the longitudinal direction of the machine 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. The false twisting device 15 is arranged in plural in the longitudinal direction of the machine body. For example, 16 false twisting devices 15 are provided for one span.

The 2 nd yarn feeding roller 16 is a roller for feeding the yarn Y twisted by the false twisting device 15 toward the interlacing device 17. The 2 nd godet 16 is disposed on the downstream side of the main body 8 in the yarn advancing direction of the false twisting device 15. The feeding speed of the yarn Y by the 2 nd yarn feeding roller 16 is faster than the feeding speed of the yarn Y by the 1 st yarn feeding roller 11. Thus, the yarn Y is stretched between the 1 st godet 11 and the 2 nd godet 16.

The interlacing device 17 is a device for applying interlacing by spraying air to the yarn Y. The winding device 17 is disposed below the 2 nd godet 16 in the main body 8.

The 3 rd godet 18 is a roller for conveying the yarn Y subjected to the interlacing by the interlacing device 17 toward the 2 nd heating device 19. The 3 rd godet 18 is disposed below the winding device 17 in the main body 8. The 3 rd godet 18 delivers the yarn Y at a slower rate than the 2 nd godet 16 delivers the yarn Y. Thus, the yarn Y is relaxed between the 2 nd and 3 rd godets 16 and 18.

The 2 nd heating device 19 is a device for heating the yarn Y fed from the 3 rd godet 18. The 2 nd heating device 19 is disposed below the 3 rd godet 18 in the main body 8. The 2 nd heating devices 19 extend in the up-down direction, one each being provided in one span.

The 4 th godet 20 is a roller for feeding the yarn Y heat-treated by the 2 nd heating device 19 toward the winding device 21. The 4 th godet 20 is disposed below the winding stage 9. The 4 th godet 20 delivers the yarn Y at a slower rate than the 3 rd godet 18 delivers the yarn Y. Thus, the yarn Y is relaxed between the 3 rd and 4 th godets 18 and 20.

In the processing unit 3 configured as described above, the yarn Y stretched between the 1 st yarn feeding roller 11 and the 2 nd yarn feeding roller 16 is twisted by the false twisting device 15. The twist formed by the false twisting device 15 propagates to the anti-twist yarn guide 12, but does not propagate to the upstream side of the anti-twist yarn guide 12 in the yarn advancing direction. The yarn Y twisted while being stretched is heated by the 1 st heating device 13 and heat-set, and then cooled by the cooling device 14. The yarn Y is untwisted downstream of the false twisting device 15, but the above-described heat setting maintains the state in which each filament is false twisted in a wavy form. The yarn Y false-twisted by the false twisting device 15 is relaxed between the 2 nd godet 16 and the 3 rd godet 18, is submitted to interlacing by the interlacing device 17, and is guided to the downstream side in the yarn traveling direction. Further, the yarn Y is relaxed between the 3 rd and 4 th godets 18 and 20, and is heat-set by the 2 nd heating device 19. Finally, the yarn Y fed from the 4 th godet 20 is wound by the winding device 21 to form a winding package Pw.

(constitution of winding portion 4)

The winding section 4 has a plurality of winding devices 21. The winding device 21 is a device for winding the yarn Y fed from the 4 th godet 20 around the bobbin Bw to form a winding package Pw (package of the present invention). The bobbin Bw is a tubular member, for example.

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

The pair of cradle arms 30 are disposed so as to face each other in the longitudinal direction of the machine body. The pair of cradle arms 30 can rotatably support the bobbin holder 70. The pair of cradle arms 30 is configured to be capable of holding the bobbin Bw via the bobbin holder 70. The rocker arm 30 forms a winding package Pw by winding a wire around a bobbin Bw held by the bobbin holder 70. The pair of cradle arms 30 are opened in the longitudinal direction of the machine body, whereby 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 are movable between the winding position and the release position by rotating about a swing shaft 31 extending in the axial direction of the bobbin holder 70, that is, in the longitudinal direction of the machine body. As shown in fig. 2, the winding position is a position where the yarn Y is wound on the bobbin Bw attached to the bobbin holder 70 to form the winding package Pw. The cradle arm 30 is configured such that the center x1 of the winding package Pw moves from the other side in the machine body width direction to one side as the package diameter of the winding package Pw supported by the cradle arm 30 increases. In other words, as the package diameter of the winding package Pw during winding becomes larger, the winding position of the cradle arm 30 moves from the other side in the machine body width direction toward one side. As shown in fig. 3, the release position is a position of the cradle arm 30 when the gripping of the winding package Pw by the bobbin holder 70 is released, and is a position at which the released winding package Pw can be sent out to the package storage section 50. The center x1 of the winding package Pw supported by the cradle arm 30 substantially coincides with the axial center of the bobbin holder 70.

The contact roller 40 is configured to rotate and drive in a predetermined direction while being in contact with the outer peripheral surface of the bobbin Bw or the winding package Pw, thereby rotating the bobbin Bw to wind the yarn Y. The contact roller 40 is of a so-called wire drive type connected to a drive shaft shared by the winding devices 21, that is, shared by a plurality of spindles, and is driven by a motor not shown. As shown in fig. 3, the contact roller 40 is disposed on the other side with respect to a vertical plane F passing through the axis of the bobbin holder 70 supported by the cradle arm 30 in the release position. In the present embodiment, the vertical surface F is a surface parallel to the vertical direction and the longitudinal direction of the machine body. In the present embodiment, the other side with respect to the vertical plane F is the other side in the body width direction (right side of the drawing sheet of fig. 3) with respect to the vertical plane F. As shown in fig. 3, the contact roller 40 is disposed at a position lower than the stocker 60 in the vertical direction.

The package storage unit 50 stores the wound package Pw released from the cradle arm 30 at the release position. In the present embodiment, the package storage unit 50 can store at most 2 winding packages Pw. As shown in fig. 3, the package storage 50 is disposed on one side with the vertical plane F as a boundary. In the present embodiment, the side bordered by the vertical plane F is the side in the body width direction (left side of the drawing of fig. 3) with respect to the vertical plane F.

As shown in fig. 2, the package storage 50 has two rails 53 disposed to face each other in the longitudinal direction of the machine body. In fig. 2, only the rail 53 is shown as being disposed on the front side of the paper surface of the winding package Pw stored in the package storage 50 in the longitudinal direction of the machine body, but the rail 53 is actually disposed on the back side of the paper surface of the winding package Pw stored in the package storage 50 in the longitudinal direction of the machine body. The interval between the two rails 53 in the longitudinal direction of the machine body is slightly smaller than the width of the bobbin Bw in the longitudinal direction of the machine body, and is larger than the width of the winding package Pw formed by winding the yarn Y on the bobbin Bw in the longitudinal direction of the machine body. The winding package Pw delivered to the package storage 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 assembly 50 is inclined downward from the vertical plane F toward one side, that is, from the other side (right side of the drawing sheet in fig. 3) toward one side (left side of the drawing sheet in fig. 3) in the machine body width direction. The rail 53 of the package storage 50 is similarly inclined downward from the other side in the machine body width direction toward one side. Accordingly, the winding package Pw released from the cradle arm 30 rolls from the other side in the machine body width direction along the upper surface 51 of the downward-inclined rail 53. Further, a member (not shown) for preventing the wound package Pw from rolling further toward one side in the machine body width direction is formed at one end of the package storage section 50 in the machine body width direction.

In the package storage unit 50, in addition to the winding package Pw stored as a full package, a winding package Pw in the middle of winding the wire Y when a break occurs in the middle of winding the wire Y by the winding device 21 is stored.

The stocker 60 stores bobbins Bw for supply to the cradle arm 30. In the present embodiment, the stocker 60 can store up to 4 bobbins Bw. The bobbin Bw stored in the stocker 60 is an empty bobbin Bw in a state where the yarn Y is not wound. As shown in fig. 2, the stocker 60 extends such that the front end portion on one side in the machine body width direction is lower than the rear end portion on the other side. Hereinafter, the extending direction of the stocker 60 will be referred to as an extending direction (see fig. 5). As shown in fig. 2, the stocker 60 is disposed at a position higher than the package storage 50 and the contact roller 40 in the vertical direction. The detailed configuration of the stocker 60 will be described later.

The moving mechanism 80 is configured 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 in standby when the supply of the bobbin Bw from the stocker 60 to the cradle arm 30 is not performed (see fig. 2 and 3). Specifically, the standby position is a position where the stocker 60 is in standby when the winding package Pw is released from the cradle arm 30 in the release position and conveyed to the package storage 50 when the yarn Y is wound on the bobbin Bw supported by the cradle arm 30 in the forward direction. 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 disposed on the other side with the vertical plane F as a boundary. The supply position is a position of the stocker 60 for supplying the bobbin Bw to the bobbin holder 70 supported by the cradle arm 30 in the release position and in which the bobbin Bw formed with the winding package Pw is removed (see fig. 4). As shown in fig. 4, when the stocker 60 is at the supply position, the axis of the bobbin Bw located on the most side in the machine body width direction among the plural bobbins Bw stored in the stocker 60 coincides with the axis of the bobbin holder 70 supported by the cradle arm 30 at the release position.

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 the present embodiment, the stocker 60 is mounted below the moving mechanism 80.

(constitution of hopper 60)

Next, the detailed configuration of the stocker 60 will be described below with reference to fig. 2 to 7. The stocker 60 includes a supporting surface 61, a restricting portion 62, a stopper 63, a 2 nd restricting portion 64, a tip supporting portion 65, and a rotation shaft 66 (corresponding to the 1 st rotation shaft and the 2 nd rotation shaft of the present invention).

The support surface 61 supports a 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 machine body width direction is lower than the other end in the machine body width direction. In other words, the support surface 61 extends along the extending direction of the stocker 60. Accordingly, the bobbin Bw stored in the stocker 60 moves from the other side to one side in the machine body width direction along the inclination of the supporting surface 61.

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

The restricting portion 62 is a member for preventing the bobbin Bw stored in the stocker 60 from coming off the stocker 60. The restricting portions 62 are disposed to face each other in the longitudinal direction of the machine body. The spacing between the opposed regulating portions 62 in the longitudinal direction of the machine body is larger than the width of the bobbin Bw in the longitudinal direction of the machine body. The restricting portion 62 is configured to be switchable between a restricting state (the state of fig. 2, 3, and 6) in which the bobbin Bw stored in the stocker 60 is prevented from coming off the stocker 60, and a releasing state (the state of fig. 4 and 7) in which the restricting state is released. As the stocker 60 moves from the standby position to the supply position, the restriction portion 62 rotates in the 1 st direction D1 (see the solid arrow in fig. 6) about the rotation shaft 66, and is switched from the restriction state to the release state. The 1 st direction D1 is the clockwise direction in fig. 6. As the stocker 60 moves from the supply position to the standby position, the regulating portion 62 rotates about the rotation shaft 66 in the 2 nd direction opposite to the 1 st direction D1, and is switched from the released state to the regulating state. The 2 nd direction is the counterclockwise direction in fig. 6. The state switching of the restriction portion 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 machine body. The interval between the two restricting portions 62 in the longitudinal direction of the machine body is slightly larger than the width of the bobbin Bw in the longitudinal direction of the machine body.

As shown in fig. 5, the restricting portion 62 includes a claw portion 62a, an arm portion 62b, and an abutment portion 62c. The claw 62a prevents the bobbin Bw from coming off the stocker 60 by restricting the bobbin Bw stored in the stocker 60 from moving from the other side to one side in the body width direction along the supporting surface 61. The claw portion 62a is connected to the rotation shaft 66 via an arm portion 62 b. The claw portion 62a has a plate-like shape.

As shown in fig. 2 and 5, the claw portion 62a extends downward from a front end portion of the arm portion 62b opposite to the side to which the rotation shaft 66 is connected toward one side in the body width direction. As shown in fig. 2 and 6, when the regulating portion 62 is in the regulating state, the claw portion 62a is in contact with a portion on one side in the body width direction and on the upper side of the barrel Bw on the most side in the body width direction among the barrels Bw stored in the stocker 60. Thereby, the claw portion 62a can restrict the bobbin Bw from moving along the inclined supporting surface 61. As shown in fig. 4 and 7, when the restricting portion 62 is in the released state, the claw portion 62a is prevented from coming into contact with the bobbin Bw stored in the stocker 60. Thereby, the movement restriction of the bobbin Bw by the claw portion 62a is released.

The arm 62b is connected to the rotation shaft 66 and the claw 62 a. The arm 62b can restrict the movement of the spool Bw located closest to the spool Bw in the machine body width direction among the plurality of spools Bw stored in the stocker 60 in the machine body longitudinal direction. Specifically, the arm 62b of the restricting portion 62 on the front side in the longitudinal direction of the machine body restricts the movement of the bobbin Bw stored in the stocker 60 toward the front side in the longitudinal direction of the machine body. The arm 62b of the restriction portion 62 on the back side of the paper in the longitudinal direction of the machine body restricts the movement of the bobbin Bw stored in the stocker 60 toward the back side of the paper in the longitudinal direction of the machine body.

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 abutting portion 62c is formed on one side of the arm portion 62b in the body width direction. As the stocker 60 moves from the standby position to the supply position, the abutting portion 62c abuts against 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 rotatable in the 1 st direction D1 abuts. Specifically, the stopper 63 is a portion that can be abutted by the upper portion on the other side of the arm 62b in the body width direction (see fig. 7). The stoppers 63 are disposed to face each other in the longitudinal direction of the machine body. A stopper 63 is formed at an upper portion of the hopper 60. More specifically, when 4 bobbins Bw are stored in the stocker 60, the stopper 63 is formed at the upper portion of the 2 nd bobbin Bw, when the 1 st to 4 th bobbins Bw are sequentially provided from the bobbin Bw located at one side in the machine body width direction. As shown in fig. 4 and 7, when the stocker 60 reaches the supply position, the restricting portion 62 which rotates in the 1 st direction D1 abuts against the stopper 63, and thereby the restricting portion 62 is restricted from rotating further in the 1 st direction D1.

The 2 nd regulating portion 64 is a member that suppresses the bobbin Bw stored in the stocker 60 from flying out beyond the bobbin holder 70 when the stocker 60 reaches the supply position and the regulating portion 62 is in the released state. As shown in fig. 5, the 2 nd regulating portion 64 extends from the vicinity of the end portion of the one side of the stocker 60 in the machine body width direction, and the upper portion thereof is directed to the one side in the machine body width direction, and is vertically downward. The 2 nd restriction portion 64 is an elastic member such as a leaf spring, for example. When the stocker 60 having completed the transfer of the bobbin Bw to the cradle arm 30 moves from the supply position to the standby position, the 2 nd restriction portion 64 may be caught by the bobbin Bw supported by the cradle arm 30 and interfere with the movement of the stocker 60. In this regard, the 2 nd regulating portion 64 as an elastic member is biased by being pushed upward by the bobbin Bw when coming 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. Accordingly, the 2 nd regulating portion 64 can be prevented from hooking the bobbin Bw supported by the cradle arm 30 when the stocker 60 moves from the supply position to the standby position. As shown in fig. 5, two 2 nd restricting portions 64 are arranged on the outer sides of the central portion of the hopper 60 and on the inner sides of the two restricting portions 62 in the longitudinal direction of the machine body.

The tip support portion 65 supports, from below, the bobbin Bw located on the farthest side in the machine body width direction among the plural bobbins Bw stored in the stocker 60. As shown in fig. 2 and 5, the front end support 65 is provided in the hopper 60 near the front end portion of the cradle arm 30 in the release position and is a lower portion. As shown in fig. 5, the distal end support portion 65 extends along the longitudinal direction of the machine body. As shown in fig. 6 and 7, the front end support portion 65 is bent in a V-shape at one side in the machine body width direction when viewed along the machine body longitudinal direction. The tip support portion 65 is made of, for example, a metal plate or a resin.

The tip support portion 65 can take a restricting posture for preventing the bobbin Bw from coming off the stocker 60. When the tip support portion 65 is in the restricting posture, the bobbin Bw is fitted into the V-shaped bent portion of the tip support portion 65, thereby preventing the bobbin Bw from coming off the stocker 60 (see fig. 6 and 7). Further, the bobbin Bw is fitted into the V-shaped bent portion of the tip end support portion 65 in the restricting posture, whereby the bobbin Bw can be accurately positioned. Accordingly, 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 at the release position. The tip support portion 65 is rotatable about a rotation shaft 66. In the present embodiment, the restricting portion 62 is shared with the rotation shaft 66 of the tip support portion 65.

Further, the stocker 60 includes a biasing member 67. The biasing member 67 biases the tip support portion 65 rotatable about the rotation shaft 66 to a restricting posture. The urging member 67 is, for example, a spring member. In the present embodiment, the urging member 67 also has a function of urging the restricting portion 62 rotatable about the rotation shaft 66 to bring the restricting portion into a restricting state.

(supply operation of the bobbin Bw from the stocker 60 to the cradle arm 30)

Next, the following describes the operation of the stocker 60 moving between the standby position and the supply position and the respective constituent parts accompanying this operation when supplying the bobbin Bw to the cradle arm 30.

As described above, the stocker 60 is at the standby position (see fig. 2 and 3) during the winding of the yarn Y by the winding device 21 and when the winding package Pw is released from the cradle arm 30 at the release position and is transported to the package storage 50. When the stocker 60 is at the standby position, the restricting portion 62 is in the restricting state, and the front end supporting portion 65 takes the restricting posture (see fig. 2 and 3).

When the winding package Pw is released from the cradle arm 30 in the release position and is transferred to the package storage 50, the moving mechanism 80 linearly moves the stocker 60 from the standby position toward the supply position. In the present embodiment, the stocker 60 at the standby position moves linearly toward one side in the machine body width direction and in a downward inclined direction (a direction obliquely downward to the left in fig. 3). In the present embodiment, the extending direction of the stocker 60 is substantially identical to the moving direction of the stocker 60. Fig. 6 shows the stocker 60 in the middle from the standby position toward the supply position.

The abutting portion 62c contacts the bobbin holder 70 supported by the cradle arm 30 at the release position, while the stocker 60 is moving from the standby position to the supply position. More specifically, in fig. 3, 4, and the like, the abutting portion 62c of the regulating portion 62 disposed on the back side of the paper surface in the machine body longitudinal direction is in contact with the bobbin holder 70 disposed on the back side of the paper surface in the machine body longitudinal direction, and the abutting portion 62c of the regulating portion 62 disposed on the front side of the paper surface in the machine body longitudinal direction is in contact with the bobbin holder 70 disposed on the front side of the paper surface in the machine body longitudinal direction. As the stocker 60 moves further toward the supply position from the state where the abutting portion 62c is in contact with the bobbin holder 70, the abutting portion 62c is pushed by the bobbin holder 70. Thereby, the regulating portion 62 of the stocker 60 is rotated in the 1 st direction D1 (see fig. 6) about the rotation shaft 66, and is switched from the regulating state to the releasing state. When the stocker 60 reaches the supply position, the restricting portion 62 is released (see fig. 4 and 7). In fig. 6 and 7, for convenience of explanation, the cradle arm 30 and the bobbin holder 70 on the front side of the plane of the drawing in the longitudinal direction of the machine body are omitted.

As shown in fig. 7, when the stocker 60 reaches the supply position, the restricting portion 62 abuts against the stopper 63. Thereby, the restricting portion 62 is restricted from further rotating in the 1 st direction D1. In other words, the regulating portion 62 is sandwiched by the bobbin holder 70 supported by the cradle arm 30 in the release position and the stopper 63, whereby the rotation of the regulating portion 62 is regulated, and the stocker 60 is regulated from further moving beyond the supply position.

When the stocker 60 reaches the supply position, the bobbin Bw supported from below by the tip support portion 65 among the plural bobbins Bw stored in the stocker 60 is mounted on the bobbin bracket 70 supported by the cradle arm 30 in the release position. More specifically, since the regulating portion 62 is released when the stocker 60 reaches the supply position, the regulation of the arm portion 62b is released at both sides in the longitudinal direction of the bobbin Bw supported from below by the tip support portion 65 (see fig. 7). In this state, the bobbin holder 70 closes the inside in the machine body longitudinal direction from both sides of the bobbin Bw in the machine body longitudinal direction with respect to the hollow portion of the cylindrical bobbin Bw, whereby the bobbin Bw is sandwiched by the bobbin holder 70.

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 from the supply position to the standby position, and then moves away from the cradle arm 30 at the release position to the other side in the body width direction. Thus, the regulating portion 62c, which is in contact with the bobbin holder 70 supported by the cradle arm 30 at the release position, rotates about the rotation shaft 66 in the 2 nd direction opposite to the 1 st direction D1, and is switched from the release state to the regulating state. Then, the contact between the abutting portion 62c and the bobbin holder 70 is released, and the regulating portion 62 returns to the regulating state by the urging force of the urging member 67.

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 pushed by the bobbin Bw supported by the cradle arm 30 in the release position. Thereby, the tip support portion 65 rotates around the rotation shaft 66 against the biasing force of the biasing member 67 so as to avoid the bobbin Bw. In other words, the distal end support portion 65 rotates about the rotation shaft 66 against the urging force of the urging member 67 so that the distal end portion is lower than the proximal end portion connected to the rotation shaft 66. Then, when the stocker 60 further moves toward the standby position and the tip support portion 65 and the bobbin Bw become out of contact, the tip support portion 65 returns to the restricting posture by the urging force of the urging member 67. In addition, the bobbin Bw remaining in the stocker 60 moves along the inclined supporting surface 61 in the middle of the stocker 60 returning from the supply position to the standby position. Then, the bobbin Bw located on the most side in the machine body width direction among the plural bobbins Bw remaining in the stocker 60 is supported from below by the tip support part 65 returned to the restricting posture.

By 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 the present embodiment includes a package storage 50 disposed on one side of the vertical surface F, a stocker 60 disposed on the other side of the vertical surface F, and a moving mechanism 80 for moving 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 does not pass through the position above both the standby position and the supply position in the middle of the movement from the standby position to the supply position, and it is not necessary to secure a separate space above the winding device 21. However, even when the stocker 60 is linearly moved, for example, when the stocker 60 is disposed above the package storage 50 as in patent document 2, the position of the stocker 60 increases, and there is a limit in reducing the height dimension of the winding device 21. The reason for this is that the wound package Pw released from the cradle arm 30 passes under the stocker 60 and is conveyed to the package storage 50, and therefore, the distance between the stocker 60 and the package storage 50 needs to be increased to such an extent that the wound package Pw can pass. In this regard, in the present embodiment, the stocker 60 is disposed on the opposite side of the package storage 50 with respect to the vertical plane F. Accordingly, since the stocker 60 can be arranged at a low position and the stocker 60 does not pass through a position above both the standby position and the supply position, the height of the winding device 21 can be effectively suppressed.

In the winding device 21 of the present embodiment, the stocker 60 is provided with a regulating portion 62 that can be switched between a regulating state and a releasing state. The restricting portion 62 is released when the stocker 60 reaches the supply position. Accordingly, the bobbin Bw can be prevented from falling off the stocker 60 by the restriction portion 62 in the restricted state before the stocker 60 reaches the supply position. Further, since the regulating portion 62 is released when the stocker 60 reaches the supply position, the supply of the bobbin Bw from the stocker 60 to the cradle arm 30 is not hindered by the regulating portion 62. This enables the storage of the bobbin Bw by the stocker 60 to be reliably performed, and the bobbin Bw to be appropriately supplied from the stocker 60 to the cradle arm 30.

In the winding device 21 of the present embodiment, the regulating portion 62 has an abutment portion 62c that can abut against the bobbin holder 70 supported by the cradle arm 30 in the released position. The restricting portion 62 is configured to switch from the restricting state to the releasing state by rotating the abutting portion 62c in the 1 st direction D1 about the rotation shaft 66 by being pressed by the bobbin holder 70 as the stocker 60 moves from the standby position to the supply position. The regulating portion 62 is configured to be switched from the released state to the regulated state by rotating the abutting portion 62c about the rotation shaft 66 in the 2 nd direction opposite to the 1 st direction D1 by releasing the abutting portion 62c from the contact with the bobbin holder 70 as the stocker 60 moves from the supply position to the standby position. Accordingly, the release state and the restriction state of the restriction portion 62 can be switched according to whether or not the abutting portion 62c contacts the bobbin holder 70 with the movement of the stocker 60. Therefore, a driving source for switching the state of the restriction portion 62 is not required.

In the winding device 21 of the present embodiment, the stocker 60 has a stopper 63 that can abut against the restricting section 62 that rotates in the 1 st direction D1. When the stocker 60 reaches the supply position, the abutting portion 62c is pressed by the bobbin holder 70, and the restricting portion 62 which is rotated in the 1 st direction D1 is restricted from being rotated further in the 1 st direction D1 by abutting against the stopper 63. Accordingly, the abutting portion 62c of the restricting portion 62 is restricted from being further pushed by the bobbin holder 70, that is, the stocker 60 is restricted from being further moved. This can prevent the stocker 60 from further moving beyond the supply position, and can properly supply the bobbin Bw from the stocker 60 to the cradle arm 30.

In the winding device 21 of the present embodiment, the 2 nd regulating portion 64 is provided in the stocker 60, and when the stocker 60 reaches the supply position and the regulating portion 62 is in the released state, the 2 nd regulating portion 64 regulates the bobbins Bw stored in the stocker 60 from flying out beyond the bobbin holder 70. When the stocker 60 moves from the standby position to the supply position, an inertial force acts on the bobbin Bw. Therefore, even after the stocker 60 reaches the supply position, the bobbin Bw moves over 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 restriction 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 over the rocker arm 30. In this case, the bobbin Bw cannot be properly supplied to the cradle arm 30. According to the present embodiment, since the 2 nd regulating portion 64 is provided, when the stocker 60 reaches the supply position, the bobbin Bw can be restrained from moving beyond the cradle arm 30 at the release position due to the inertial force. This makes it possible to more reliably supply the bobbins Bw from the stocker 60 to the cradle arm 30.

In the winding device 21 of the present embodiment, a tip end support portion 65 for supporting the bobbin Bw from below is provided at the tip end portion of the cradle arm 30 in the stocker 60 near the release position. The tip support portion 65 can take a restricting posture for preventing the bobbin Bw from coming off the stocker 60 and can rotate about the rotation shaft 66. The stocker 60 further includes a biasing member 67 that biases the front end support portion 65 to a restricting posture. When the stocker 60 moves from the supply position to the standby position, the tip support portion 65 is pressed by the bobbin Bw supported by the cradle arm 30 in the release position, and thereby rotates around the rotation shaft 66 against the urging force of the urging member 67 so as to avoid the bobbin. In the present embodiment, since the tip support portion 65 is provided, the bobbin Bw stored in the stocker 60 can be prevented from coming off the stocker 60. On the other hand, when the stocker 60 is to return to the standby position after the supply of the bobbin Bw from the stocker 60 to the cradle arm 30 is completed, the tip support portion 65 to prevent the bobbin Bw from coming off may be caught by the bobbin Bw supported by the cradle arm 30 to interfere with the movement of the stocker 60. According to the present embodiment, when the stocker 60 returns from the supply position to the standby position, the front end supporting portion 65 rotates so as to avoid the bobbin Bw supported by the cradle arm 30. Therefore, the tip support portion 65 can be prevented from being caught by the bobbin Bw supported by the cradle arm 30, and the movement of the stocker 60 to the standby position can be prevented. Therefore, the stocker 60 can be smoothly returned to the standby position after the bobbin Bw is supplied to the cradle arm 30, and the winding operation of the wire Y thereafter can be rapidly performed.

(modification)

A modified example in which the above-described embodiment is modified will be described below. However, elements having the same configuration as those of the above embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

In the above embodiment, the regulating portion 62 is configured to switch from the regulating state to the releasing state by the abutting portion 62c being pressed by the bobbin holder 70 as the stocker 60 moves from the standby position to the supply position. However, the restricting portion 62 that can be switched between the restricting state and the releasing state is not limited to the above configuration. For example, the restricting portion 62 may be switchable between the restricting state and the releasing state by an electric motor.

In the above embodiment, the restricting portion 62 is rotatable about the rotation shaft 66 to switch between the restricting state and the releasing state. However, the restricting portion 62 is not limited to the configuration of rotating around the rotation shaft 66. For example, the restricting portion 62 may be configured to be capable of switching between the restricting state and the releasing state by sliding in a direction intersecting the extending direction of the stocker 60.

In the above embodiment, the stocker 60 at the standby position is linearly moved in the direction substantially coincident with the extending direction of the stocker 60, and in the downward inclined direction (the downward left inclined direction of the drawing sheet in fig. 3) toward one side in the machine body width direction. However, the stocker 60 in the standby position may be linearly moved in an upward oblique direction (for example, a direction obliquely upward to the left of the drawing sheet in fig. 3) and in a horizontal direction toward one side in the machine body width direction. In this case, a pushing mechanism or the like for pushing out the bobbin Bw stored in the stocker 60 from the rear end portion toward the front end portion of the stocker 60 in the extending direction is arranged in the stocker 60. The extending direction of the stocker 60 may not be substantially equal to the direction in which the stocker 60 linearly moves.

In the above embodiment, one rotation shaft 66 corresponds to both the 1 st rotation shaft and the 2 nd rotation shaft of the present invention. However, the 1 st rotation axis, which is the rotation center of the restricting portion 62, and the 2 nd rotation axis, which is the rotation center of the tip supporting portion 65, may be provided separately.

In the above embodiment, the stocker 60 has the restricting portion 62 that can be switched between the restricting state and the releasing state. However, the stocker 60 may not have the restriction portion 62. In this case, the stocker 60 is preferably provided with a member for preventing the bobbin Bw from coming off the stocker 60 in the standby position and the stocker 60 moving from the standby position toward the supply position.

In the above embodiment, the stocker 60 has the 2 nd regulating portion 64, and when the regulating portion 62 is in the released state, the 2 nd regulating portion 64 suppresses the bobbin Bw stored in the stocker 60 from flying out beyond the bobbin holder 70. However, the stocker 60 may not have the 2 nd restriction portion 64. In this case, the moving mechanism 80 preferably sets the moving speed of the stocker 60 moving from the standby position to the supply position to a predetermined speed or less. The predetermined speed is a speed at which the bobbin Bw can be prevented from flying out from the stocker 60 reaching the supply position beyond the bobbin holder 70. Accordingly, 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 embodiment, the two 2 nd restricting portions 64 are provided on the outer sides of the central portion of the stocker 60 and on the inner sides of the two restricting portions 62 in the longitudinal direction of the main body. However, the 2 nd restriction portion 64 is not limited to two. For example, one or three or more restricting portions 64 may be provided.

In the above embodiment, the stocker 60 has the front end supporting portion 65. However, the stocker 60 may not have the front end support portion 65. In this case, the hopper 60 is preferably provided with the 2 nd restriction portion 64.

The winding device 21 of the above embodiment is applied to the false twist texturing machine 1. However, the winding device 21 of the present invention is not limited to the false twist 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 be moved between the winding position and the release position, and may be a fixed cradle arm in the case of a line drive type in which the contact roller 40 is not connected to a drive shaft common to a plurality of spindles (see japanese patent application laid-open No. 2015-40116, for example). In this case, the winding position and the release position of the cradle arm are the same position.
