Description

The present invention relates to a winding device.

Patent Document 1 discloses a false twisting machine that includes a false twisting device that applies false twist to yarn supplied from a yarn feeding section, and a winding device that winds up the yarn to which the false twist has been applied. There is. The winding device has a cradle that rotatably supports a set of bobbin holders, and forms a package by winding yarn around a bobbin (paper tube of Patent Document 1) attached to the bobbin holders.

When a fully wound package is formed in such a winding device, the package is removed from the cradle and a new bobbin is fed to the cradle. Patent Document 2 discloses a package storage section (guide rail in Patent Document 2) that supports a package removed from a cradle, and a stocker (paper stocker in Patent Document 2) that stores a plurality of empty bobbins lined up to be supplied to the cradle. A winding device (doffing device of Patent Document 2) having a pipe stocker) is described.

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 in a standby position (the position shown in Figure 2) above the package storage section when winding the thread, and swings around the rotation axis when feeding the bobbin to the cradle. The feeding position is moved to the supply position below the standby position and on the right side of the paper in FIG.

Japanese Patent Application Publication No. 2011-47074 Japanese Patent Application Publication No. 9-86799

In the device of Patent Document 2, as shown in FIG. 2, when the stocker is located at the standby position, the support bracket that supports the stocker is tilted diagonally upward and to the left 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 tilted diagonally upward and to the right from the rotation axis. That is, in the process of moving the stocker from the standby position to the supply position, the support bracket goes from being tilted diagonally upward to the left, to being vertically oriented, and then to being tilted diagonally upward to the right. In this case, 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 a space above the winding device so that the stocker does not interfere with other members during the process of moving from the standby position to the supply position. However, by securing such a space, the substantial height dimension of the winding device becomes large.

An object of the present invention is to suppress an increase in the height of a winding device.

The winding device of the present invention is capable of rotatably supporting a bobbin holder, forms a package by winding yarn around the bobbin held by the bobbin holder, and releases the package from the grip of the bobbin holder. a cradle that can store the package released from the cradle, a stocker that stores the bobbin to be supplied to the cradle, a standby position for the stocker, and a package storage section that stores the package released from the cradle; a moving mechanism for moving the bobbin to and from a supply position for supplying the bobbin to the cradle in a release position in which grip is released, the package storage section being supported by the cradle in the release position. The stocker is disposed on one side of a vertical plane passing through the axis of the bobbin holder and is in the standby position, and the stocker is disposed on the other side of the vertical plane as a boundary, and the moving mechanism is in the standby position and The present invention is characterized in that the stocker is moved linearly to and from the supply position.

According to the invention, the stocker can be moved from the standby position to the supply position by moving linearly. Therefore, while the stocker moves 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 moving the stocker linearly, for example, if the stocker is arranged above the package storage part as in Patent Document 2, the position of the stocker becomes high, and the height of the winding device increases. There is a limit to the reduction of This is because the packages released from the cradle are sent to the package storage section through the bottom of the stocker, so the distance between the stocker and the package storage section needs to be large enough to allow the packages to pass through. . In this regard, in the present invention, the stocker is arranged on the opposite side of the package storage section with the vertical plane as a boundary. Therefore, while the stocker is placed at a low position, it is possible to prevent the stocker from passing through a position above both the standby position and the supply position, so the height of the winding device can be effectively suppressed. can.

In the winding device of the present invention, a front end of the stocker close to the cradle in the release position has a regulating state that prevents the bobbin stored in the stocker from falling off from the stocker; It is preferable that a regulating part is provided that can be switched between the regulating state and a released state in which the regulating state is released, and the regulating part is in the released state when the stocker reaches the supply position.

According to the present invention, until the stocker reaches the supply position, the regulating section in the regulating state can prevent the bobbin from falling off from the stocker. Furthermore, since the restriction part is in the released state when the stocker reaches the supply position, the restriction part does not obstruct the supply of the bobbin from the stocker to the cradle. Thereby, the bobbins can be properly stored from the stocker to the cradle while the bobbins are reliably stored in the stocker.

In the winding device of the present invention, the stocker has a first rotation axis along the axial direction of the bobbin holder, and the restriction portion can come into contact with the bobbin holder supported by the cradle in the release position. the abutting portion, and as the stocker moves from the standby position to the supplying position, the abutting portion is pushed by the bobbin holder, thereby moving the stocker in a first direction about the first rotation axis. and switches from the restricted state to the released state, and as the stocker moves from the supply position to the standby position, the contact portion and the bobbin holder are released from contact, It is preferable that the release state be switched to the restricted state by rotating in a second direction opposite to the first direction about a first rotation axis.

According to the present invention, the restriction portion can be switched between the released state and the restriction state depending on whether or not the abutting portion and the bobbin holder come into contact with each other as the stocker moves. Therefore, a drive source for switching the state of the regulating section is not required.

In the winding device of the present invention, the stocker has a stopper that the regulating portion rotating in the first direction can abut, and when the stocker reaches the supply position, the abutting portion It is preferable that the restriction portion, which rotates in the first direction by being pushed by the bobbin holder, is restricted from further rotation in the first direction by coming into contact with the stopper.

According to the present invention, the restriction portion that rotates in the first direction as the stocker moves is restricted from further rotation in the first direction by coming into contact with the stopper. Therefore, the bobbin holder restricts further pushing of the abutting portion of the restricting portion, that is, further movement of the stocker is restricted. Thereby, it is possible to prevent the stocker from further moving beyond the supply position, and it is possible to appropriately supply the bobbin from the stocker to the cradle.

In the winding device of the present invention, when the stocker reaches the supply position and the regulating portion enters the released state, the bobbin stored in the stocker is prevented from jumping out beyond the bobbin holder. It is preferable that a second restriction part is provided in the stocker.

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 tends to move beyond the cradle in the release position along the direction in which the stocker moves. However, when the stocker reaches the supply position, the regulating section is in a released state, and therefore cannot regulate the movement of the bobbin. Therefore, there is a risk that the bobbin stored in the stocker may move beyond the cradle. In this case, the bobbin cannot be properly fed to the cradle. According to the present invention, since the second restriction part is provided, when the stocker reaches the supply position, it is possible to suppress the bobbin from moving beyond the cradle at the release position due to inertia force. . Thereby, bobbins can be more reliably fed from the stocker to the cradle.

In the winding device of the present invention, a front end support part that supports the bobbin from below is provided at a front end portion of the stocker near the cradle in the release position, and the front end support part supports the bobbin from below. The stocker is capable of taking a restricting posture that prevents the bobbin from falling off from the stocker, and is rotatable about a second rotation axis along the axial direction of the bobbin holder, and the stocker is arranged so that the front end The front end support part further includes a biasing member that biases the support part to take the regulating position, and the front end support part is configured to support the cradle in the release position when the stocker moves from the supply position to the standby position. By being pushed by the bobbin supported by the bobbin, it is preferable to rotate about the second rotation axis so as to avoid the bobbin, against the urging by the urging member.

In the present invention, by providing the front end support portion, the bobbin stored in the stocker is prevented from falling off from the stocker. On the other hand, when the stocker attempts to return to the standby position after the supply of bobbins from the stocker to the cradle is completed, the front end support part that tries to prevent the bobbin from falling off and the bobbin supported by the cradle get caught, and the stocker There is a risk that the movement of the According to the present invention, when the stocker returns from the supply position to the standby position, the front end support rotates to avoid the bobbin supported by the cradle. Therefore, it is possible to avoid the front end support portion and the bobbin supported by the cradle from getting caught and preventing the stocker from moving to the standby position. Therefore, the stocker can be smoothly returned to the standby position after the bobbin is supplied to the cradle, and the subsequent thread winding operation can be performed promptly.

Embodiments of the present invention will be described below with reference to the drawings.

(Overall configuration of false twisting machine 1)
FIG. 1 is a side view showing a schematic configuration of a false twisting machine 1 according to the present embodiment. Hereinafter, the direction perpendicular to the plane of FIG. 1 will be referred to as the longitudinal direction of the machine frame, and the left-right direction of the plane of FIG. 1 will be defined as the width direction of the machine frame. The direction in which both the longitudinal direction of the machine and the width of the machine are perpendicular is defined as the vertical direction in which gravity acts. The following will explain using the above direction words as appropriate.

The false twisting machine 1 is configured to be able to false twist a yarn Y made of synthetic fiber such as nylon (polyamide fiber), for example. The false twisting machine 1 includes a yarn feeding section 2 for supplying yarn Y, a processing section 3 for false twisting the yarn Y supplied from the yarn feeding section 2, and a processing section 3 for false twisting the yarn Y processed by the processing section 3. It includes a winding section 4 that winds the winding around the bobbin Bw. Each component included in the yarn feeding section 2, processing section 3, and winding section 4 is constructed on a yarn running surface (Fig. 1 A plurality of them are arranged in the machine longitudinal direction perpendicular to the plane of the paper).

(Yarn feeding section 2)
The yarn supply section 2 has a creel stand 7 that holds a plurality of yarn supply packages Ps, and supplies a plurality of yarns Y to the processing section 3. The processing section 3 includes, in order from the upstream side in the yarn running direction, a first feed roller 11, a twist guide 12, a first heating device 13, a cooling device 14, a false twisting device 15, a second feed roller 16, an interlacing device 17, The configuration includes a third feed roller 18, a second heating device 19, and a fourth feed roller 20. The winding unit 4 winds the yarn Y that has been false twisted in the processing unit 3 onto a bobbin Bw using a winding device 21 to form a winding package Pw.

Further, the false twisting machine 1 has a main machine stand 8 and a winding stand 9 arranged at intervals in the width direction of the machine stand. The main machine stand 8 and the winding stand 9 extend substantially the same length in the longitudinal direction of the machine stand, and are arranged to face each other. The upper part of the main machine stand 8 and the upper part of the winding stand 9 are connected by a support frame 10. Each device constituting the processing section 3 is mainly attached to the main machine stand 8 and the support frame 10. The main machine stand 8, the winding table 9, and the support frame 10 form a work space 22 in which an operator performs operations such as threading on each device. The yarn path is formed so that the yarn Y mainly runs around the work space 22.

The false twisting machine 1 has a unit called a span, which includes a set of a main machine stand 8 and a winding stand 9 that are arranged opposite to each other. In one span, each device is arranged so that a plurality of yarns Y running in a line in the longitudinal direction of the machine can be simultaneously subjected to false twisting. As an example, the winding table 9 included in one span is provided with a total of 16 winding devices 21 arranged in four stages and four rows. In the false twisting machine 1, this span is arranged symmetrically on the paper with the center line C of the main machine stand 8 in the width direction of the machine stand being the axis of symmetry (the main machine stand 8 is the same for the left and right spans). ), and a plurality of them are arranged in the longitudinal direction of the machine.

(Configuration of processing section)
Next, each component of the processing section 3 will be explained. The first feed roller 11 is for feeding the yarn Y supplied from the yarn feeding section 2 to the first heating device 13 . The first feed roller 11 is arranged above the take-up table 9 (see FIG. 1). The first feed rollers 11 are arranged in one row in the longitudinal direction of the machine.

The twist stopper guide 12 is for preventing the twist imparted to the yarn Y by a false twisting device 15, which will be described later, from propagating upstream of the twist stopper guide 12 in the yarn running direction. The twist guide 12 is arranged downstream of the first feed roller 11 in the yarn running direction and upstream of the first heating device 13 in the yarn running direction. For example, the twist guides 12 are individually provided for the plurality of yarns Y supplied from the yarn feeding section 2, and are arranged in one row in the longitudinal direction of the machine.

The first heating device 13 is for heating the yarn Y sent from the first feed roller 11, and is installed on 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 feeding section 2, and are arranged in one row in the longitudinal direction of the machine.

The cooling device 14 is for cooling the yarn Y heated by the first heating device 13. The cooling device 14 is arranged downstream of the first heating device 13 in the yarn running direction and upstream of the false twisting device 15 in the yarn running direction. A plurality of cooling devices 14 are provided for the plurality of yarns Y supplied from the yarn feeding section 2, and are arranged in one row in the longitudinal direction of the machine.

The false twisting device 15 is a device for imparting twist to the yarn Y. The false twisting device 15 is arranged immediately downstream of the cooling device 14 in the yarn running direction. A plurality of false twisting devices 15 are arranged in the longitudinal direction of the machine. For example, 16 false twisting devices 15 are provided for one span.

The second feed roller 16 is a roller that feeds the yarn Y, which has been twisted by the false twisting device 15, toward the interlacing device 17. The second feed roller 16 is arranged on the main machine stand 8 on the downstream side of the false twisting device 15 in the yarn running direction. The conveyance speed of the yarn Y by the second feed roller 16 is faster than the conveyance speed of the yarn Y by the first feed roller 11. Therefore, the yarn Y is stretched between the first feed roller 11 and the second feed roller 16.

The interlacing device 17 is a device that applies entanglement to the yarn Y by jetting air thereto. The interlacing device 17 is arranged below the second feed roller 16 on the main machine stand 8 .

The third feed roller 18 is a roller that feeds the yarn Y, which has been intertwined by the interlacing device 17, toward the second heating device 19. The third feed roller 18 is arranged below the interlacing device 17 on the main machine stand 8 . The conveyance speed of the yarn Y by the third feed roller 18 is slower than the conveyance speed of the yarn Y by the second feed roller 16. Therefore, the yarn Y is relaxed between the second feed roller 16 and the third feed roller 18.

The second heating device 19 is a device for heating the yarn Y sent from the third feed roller 18. The second heating device 19 is arranged below the third feed roller 18 on the main machine stand 8 . The second heating devices 19 extend along the vertical direction, and one is provided for each span.

The fourth feed roller 20 is a roller that feeds the yarn Y that has been heat-treated by the second heating device 19 toward the winding device 21 . The fourth feed roller 20 is arranged at the bottom of the take-up table 9. The conveyance speed of the yarn Y by the fourth feed roller 20 is slower than the conveyance speed of the yarn Y by the third feed roller 18. Therefore, the yarn Y is relaxed between the third feed roller 18 and the fourth feed roller 20.

In the processing section 3 configured as described above, the yarn Y stretched between the first feed roller 11 and the second feed roller 16 is twisted by the false twisting device 15. The twist formed by the false twisting device 15 propagates up to the twist guide 12, but does not propagate upstream of the twist guide 12 in the yarn running direction. The thread Y that has been stretched and twisted is heated and heat-fixed in the first heating device 13 and then cooled in the cooling device 14. Although the yarn Y is untwisted downstream from the false twisting device 15, the state in which each filament is falsely twisted in a wavy manner is maintained by the heat fixing described above. The yarn Y that has been falsely twisted by the false twisting device 15 is loosened between the second feed roller 16 and the third feed roller 18, and is entangled by the entangling device 17, and is moved downstream in the yarn running direction. You will be guided. Furthermore, the yarn Y is thermally fixed by the second heating device 19 while being relaxed between the third feed roller 18 and the fourth feed roller 20. Finally, the yarn Y sent from the fourth feed roller 20 is wound up by the winding device 21 to form a wound package Pw.

(Configuration of winding section 4)
The winding unit 4 includes a plurality of winding devices 21. The winding device 21 is a device for winding the yarn Y sent from the fourth feed roller 20 onto a bobbin Bw to form a winding package Pw (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 (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 a state where the winding device 21 is in the process of forming the winding package Pw.

The pair of cradle arms 30 are arranged to face each other in the longitudinal direction of the machine. Each of the pair of cradle arms 30 can rotatably support the bobbin holder 70. The pair of cradle arms 30 are configured to be able to hold the bobbin Bw via the bobbin holder 70. The cradle arm 30 forms a winding package Pw by winding the yarn around the bobbin Bw held by the bobbin holder 70 . Further, the pair of cradle arms 30 can release the winding package Pw (or bobbin Bw) from the grip of the bobbin holder 70 by opening in the longitudinal direction of the machine. The pair of cradle arms 30 can be moved between a winding position and a release position by rotating around a swing shaft 31 that extends in the machine longitudinal direction, which is the axial direction of the bobbin holder 70. As shown in FIG. 2, the winding position is a position where the yarn Y is wound around the bobbin Bw attached to the bobbin holder 70 to form a winding package Pw. The cradle arm 30 is configured such that as the package diameter of the take-up package Pw supported by the cradle arm 30 increases, the center x1 of the take-up package Pw moves from the other side to the one side in the machine width direction. There is. In other words, the winding position of the cradle arm 30 moves from the other side toward the one side in the machine width direction as the package diameter of the winding package Pw being wound increases. 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 the released winding package Pw is sent to the package storage section 50. is a possible position. Note that the center x1 of the winding package Pw supported by the cradle arm 30 substantially coincides with the axis of the bobbin holder 70.

The contact roller 40 is configured to be rotated in a fixed direction while contacting the outer peripheral surface of the bobbin Bw or the winding package Pw, thereby rotating the bobbin Bw and winding the yarn Y. This contact 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 disposed on the other side of the vertical plane F passing through the axis of the bobbin holder 70 supported by the cradle arm 30 in the release position. In this embodiment, the vertical plane F is a plane parallel to the vertical direction and the machine longitudinal direction. In this embodiment, the other side of the vertical plane F is the other side of the machine width direction (the right side of the paper in FIG. 3) with respect to the vertical plane F. 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 section 50 stores the wound package Pw released from the cradle arm 30 in the release position. In this embodiment, the package storage section 50 can store up to two wound packages Pw. As shown in FIG. 3, the package storage section 50 is arranged on one side of the vertical plane F. As shown in FIG. In this embodiment, one side of the vertical plane F is one side of the machine width direction (the left side of the paper in FIG. 3) with respect to the vertical plane F.

As shown in FIG. 2, the package storage section 50 has two rails 53 arranged opposite to each other in the longitudinal direction of the machine. Although FIG. 2 only shows the rail 53 that is disposed closer to the paper than the winding packages Pw stored in the package storage section 50 in the longitudinal direction of the machine, in reality, the packages are stored in the longitudinal direction of the machine. A rail 53 is also arranged on the back side of the plane of the paper from the winding package Pw stored in the section 50. The interval between the two rails 53 in the longitudinal direction of the machine is slightly narrower than the width of the bobbin Bw in the longitudinal direction of the machine, and the distance between the two rails 53 in the longitudinal direction of the machine is slightly smaller than the width of the bobbin Bw in the longitudinal direction of the machine. greater than the width. The wound package Pw sent to the package storage section 50 is supported from below by the upper surfaces 51 of the two rails 53. More specifically, the upper surfaces 51 of the two rails 53 support both end portions of the bobbin Bw on which the winding package Pw is formed from below.

As shown in FIG. 3, the package storage section 50 is arranged in a direction from the vertical plane F to one side, that is, from the other side in the machine width direction (the right side in the paper of FIG. 3) to the one side (the left side in the paper of FIG. 3). It is sloping downward. Similarly, the rails 53 of the package storage section 50 are also inclined downward from the other side toward the one side in the machine width direction. Therefore, the winding package Pw released from the cradle arm 30 rolls from the other side to the one side in the machine width direction along the upper surface 51 of the rail 53 inclined downward. Note that a member (not shown) is formed at one end of the package storage section 50 in the machine width direction to prevent the winding package Pw from rolling further to one side in the machine width direction. There is.

In addition to the fully wound winding package Pw, the package storage section 50 stores a winding package in the middle of winding the yarn Y when yarn breakage occurs in the middle of winding the yarn Y by the winding device 21. Pw is stored.

Stocker 60 stores bobbins Bw to be supplied to 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 with no thread Y wound thereon. As shown in FIG. 2, the stocker 60 extends so that the front end on one side in the machine width direction is lower than the rear end on the other side. Hereinafter, the direction in which the stocker 60 extends will be referred to as the extending direction (see FIG. 5). As shown in FIG. 2, the stocker 60 is arranged at a higher position than the package storage section 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 for linearly moving the stocker 60 between the standby position and the supply position. The standby position is a position where the stocker 60 is 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 being wound around the bobbin Bw supported by the cradle arm 30, or when the winding package Pw is released from the cradle arm 30 in the release position and the package storage section 50 is in the standby position. This is the position where the stocker 60 is on standby when the food is being sent to the warehouse. Stocker 60 in the standby position can avoid contact with bobbin Bw or winding package Pw supported by cradle arm 30. As shown in FIG. 3, the stocker 60 in the standby position is placed on the other side of the vertical plane F. The supply position is the 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 from which the bobbin Bw on which the winding package Pw has been formed has been removed. (See Figure 4). As shown in FIG. 4, when the stocker 60 is in the supply position, the axis of the bobbin Bw closest to one side in the machine width direction among the plurality of bobbins Bw stored in the stocker 60 is in the release position. It is configured to coincide with the axis of the bobbin holder 70 supported by the cradle.

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 a standby position and a supply position. In this embodiment, a stocker 60 is attached below the moving mechanism 80.

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

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 machine width direction is lower than the other end in the machine width direction. In other words, the support surface 61 extends along the direction in which the stocker 60 extends. Therefore, the bobbin Bw stored in the stocker 60 moves from the other side toward the one side in the machine width direction along the slope of the support surface 61.

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

The regulating portion 62 is a member for preventing the bobbin Bw stored in the stocker 60 from falling off from the stocker 60. The regulating portions 62 are arranged to face each other in the longitudinal direction of the machine. The interval between the opposing regulating portions 62 in the longitudinal direction of the machine frame is larger than the width of the bobbin Bw in the longitudinal direction of the machine frame.
The regulating portion 62 is in a regulating state (states shown in FIGS. 2, 3, and 6) in which the bobbin Bw stored in the stocker 60 is prevented from falling off from the stocker 60, and in a released state in which the regulating state is released (see FIG. 4 and the state shown in FIG. 7). As the stocker 60 moves from the standby position to the supply position, the regulation part 62 rotates in the first direction D1 (see the solid arrow in FIG. 6) about the rotating shaft 66 and switches from the regulation state to the release state. . The first direction D1 is a clockwise direction in FIG. As the stocker 60 moves from the supply position to the standby position, the restriction part 62 rotates about the rotation shaft 66 in a second direction opposite to the first direction D1, and switches from the release state to the restriction state. The second direction is a counterclockwise direction in FIG. The switching of the state of the regulating portion 62 will be described in detail later. As shown in FIG. 5, two regulating portions 62 are arranged facing each other in the longitudinal direction of the machine. The interval between the two regulating portions 62 in the longitudinal direction of the machine frame is slightly larger than the width of the bobbin Bw in the longitudinal direction of the machine frame.

As shown in FIG. 5, the regulating portion 62 includes a claw portion 62a, an arm portion 62b, and an abutment portion 62c. The claw portion 62a prevents the bobbin Bw stored in the stocker 60 from moving from the other side to the one side in the machine width direction along the support surface 61, thereby preventing the bobbin Bw from falling off from the stocker 60. prevent. The claw portion 62a is connected to the rotating shaft 66 via the arm portion 62b. The claw portion 62a has a plate shape.

As shown in FIGS. 2 and 5, the claw portion 62a extends from the tip portion of the arm portion 62b opposite to the side connected to the rotating shaft 66 toward one side in the machine width direction and toward the lower side. There is. As shown in FIGS. 2 and 6, when the regulating portion 62 is in the regulating state, the claw portion 62a is attached to the bobbin that is closest to one side in the machine width direction among the plurality of bobbins Bw stored in the stocker 60. It comes into contact with the upper part of Bw on one side in the width direction of the machine. Thereby, the claw portion 62a can restrict movement of the bobbin Bw along the inclined support surface 61. Further, as shown in FIGS. 4 and 7, when the regulating 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. As a result, the restriction on movement of the bobbin Bw by the claw portion 62a is released.

The arm portion 62b is connected to the rotating shaft 66 and the claw portion 62a. The arm portion 62b is capable of restricting movement of the bobbin Bw that is closest to one side in the machine width direction out of the plurality of bobbins Bw stored in the stocker 60 in the machine machine longitudinal direction. Specifically, the arm portion 62b of the regulating portion 62 on the near side in the drawing in the longitudinal direction of the machine restricts movement of the bobbin Bw stored in the stocker 60 toward the near side in the drawing in the longitudinal direction of the machine. Further, the arm portion 62b of the regulating portion 62 on the back side of the paper in the longitudinal direction of the machine restricts movement of the bobbin Bw stored in the stocker 60 toward the back of the paper in the longitudinal direction of the machine.

The contact portion 62c is a portion that can come into contact with the bobbin holder 70 supported by the cradle arm 30 in the release position. As shown in FIG. 5, the contact portion 62c is formed on one side of the arm portion 62b in the machine width direction. The contact portion 62c contacts the bobbin holder 70 supported by the cradle arm 30 in the release position as the stocker 60 moves from the standby position to the supply position.

The stopper 63 is a portion that can be abutted by the regulating portion 62 that rotates in the first direction D1. Specifically, the stopper 63 is a portion that can be contacted by the other side and upper portion of the arm portion 62b in the machine width direction. The stoppers 63 are arranged to face each other in the longitudinal direction of the machine. The stopper 63 is formed on the top of the stocker 60. More specifically, when four bobbins Bw are stored in the stocker 60, if the first to fourth bobbins Bw are placed in order from the bobbin Bw on one side in the machine width direction, the top of the second bobbin Bw is A stopper 63 is formed at the portion. As shown in FIGS. 4 and 7, when the stocker 60 reaches the supply position, the regulating part 62 rotating in the first direction D1 comes into contact with the stopper 63, so that the regulating part 62 further rotates in the first direction D1. rotation is regulated.

The second regulating part 64 is a member that prevents the bobbin Bw stored in the stocker 60 from jumping out beyond the bobbin holder 70 when the stocker 60 reaches the supply position and the regulating part 62 is in the released state. . As shown in FIG. 5, the second regulating portion 64 extends from near one end of the stocker 60 in the machine width direction and from above towards one side in the machine width direction and downward in the vertical direction. . Further, the second regulating portion 64 is, for example, an elastic member such as a leaf spring. When the stocker 60 that has finished transferring the bobbin Bw to the cradle arm 30 moves from the supply position to the standby position, the second regulating part 64 catches the bobbin Bw supported by the cradle arm 30 and prevents the movement of the stocker 60. may be inhibited. In this regard, when the second regulating part 64, which is an elastic member, 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 is pushed upward by the bobbin Bw. bend. Thereby, when the stocker 60 moves from the supply position to the standby position, it is possible to prevent the second regulating portion 64 from getting caught with the bobbin Bw supported by the cradle arm 30. Further, as shown in FIG. 5, two second regulating portions 64 are arranged on both sides of the central portion of the stocker 60 and on the inner side of the two regulating portions 62 in the machine longitudinal direction. There is.

The front end support portion 65 supports from below the bobbin Bw that is closest to one side in the machine width direction among the plurality of bobbins Bw stored in the stocker 60 . As shown in FIGS. 2 and 5, the front end support portion 65 is provided at a front end portion and a lower portion of the stocker 60 near the cradle arm 30 in the released position. Further, as shown in FIG. 5, the front end support portion 65 extends in the longitudinal direction of the machine base. Furthermore, as shown in FIGS. 6 and 7, when viewed from the longitudinal direction of the machine, one side of the front end support portion 65 in the width direction of the machine has a V-shaped bend. The front end support portion 65 is made of, for example, sheet metal or resin.

The front end support portion 65 can take a regulating posture that prevents the bobbin Bw from falling off from the stocker 60. When the front end support part 65 is in the regulating position, the bobbin Bw fits into the V-shaped bent part of the front end support part 65, thereby preventing the bobbin Bw from falling off from the stocker 60 (see FIGS. 6 and 7). reference). Further, since the bobbin Bw fits into the V-shaped bent portion of the front end support portion 65 in the regulating posture, the bobbin Bw can be accurately positioned. Thereby, when the stocker 60 reaches the supply position, the bobbin Bw can be accurately delivered to the bobbin holder 70 supported by the cradle arm 30 in the release position. Further, the front end support portion 65 is rotatable around a rotation shaft 66. In addition, in this embodiment, the rotation shaft 66 of the restriction part 62 and the front end support part 65 is common.

Further, the stocker 60 includes a biasing member 67. The biasing member 67 is a member that biases the front end support portion 65, which is rotatable about the rotation shaft 66, so as to take a regulating attitude. The biasing member 67 is, for example, a spring member. In addition, in this embodiment, the biasing member 67 also has the role of biasing the regulating portion 62, which is rotatable about the rotation shaft 66, to be in the regulating state.

(Feeding operation of bobbin Bw from stocker 60 to cradle arm 30)
Next, the stocker 60, which moves between the standby position and the supply position when the bobbin Bw is supplied to the cradle arm 30, and the operations of the respective constituent parts thereof will be described below.

As described above, while the winding device 21 is winding the yarn Y and when the winding package Pw is released from the cradle arm 30 in the release position and sent to the package storage section 50, the stocker 60 is on standby. (see Figures 2 and 3). When the stocker 60 is in the standby position, the regulating portion 62 is in a regulating state, and the front end support portion 65 is in a regulating posture (see FIGS. 2 and 3).

When the wound package Pw is released from the cradle arm 30 in the release position and sent to the package storage section 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 width direction and in a downward diagonal direction (diagonally downward left direction in FIG. 3). In this embodiment, the direction in which the stocker 60 extends and the direction in which the stocker 60 moves substantially match. Note that FIG. 6 shows the stocker 60 on its 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 contacts the bobbin holder 70 supported by the cradle arm 30 in the release position. More specifically, in FIGS. 3 and 4, the abutting portion 62c of the regulating portion 62 located on the back side of the paper in the longitudinal direction of the machine base is connected to the bobbin holder 70 located on the back side of the paper in the longitudinal direction of the machine machine. The abutting portion 62c of the regulating portion 62 disposed on the front side of the paper in the longitudinal direction of the machine base contacts the bobbin holder 70 disposed on the front side of the paper in the longitudinal direction of the machine base. As the stocker 60 further moves to the supply position from the state where the contact portion 62c and the bobbin holder 70 are in contact, the contact portion 62c is pushed by the bobbin holder 70. As a result, the regulating portion 62 of the stocker 60 rotates in the first direction D1 (see FIG. 6) about the first rotating shaft 66, and switches from the regulating state to the releasing state. Then, when the stocker 60 reaches the supply position, the regulating portion 62 is in the released state (see FIGS. 4 and 7). Note that in FIGS. 6 and 7, for the sake of explanation, the cradle arm 30 and bobbin holder 70 on the front side in the longitudinal direction of the machine frame are omitted.

As shown in FIG. 7, when the stocker 60 reaches the supply position, the regulating portion 62 comes into contact with the stopper 63. As a result, further rotation of the restricting portion 62 in the first direction D1 is restricted. In other words, the regulation part 62 is sandwiched between the bobbin holder 70 supported by the cradle arm 30 in the release position and the stopper 63, so that the rotation of the regulation part 62 is regulated and the stocker 60 is further moved beyond the supply position. Movement is regulated.

When the stocker 60 reaches the supply position, among the plurality of bobbins Bw stored in the stocker 60, the bobbin Bw supported from below by the front end support part 65 is transferred to the bobbin holder 70 supported by the cradle arm 30 in the release position. It will be installed. To explain in more detail, when the stocker 60 reaches the supply position, the regulating part 62 is in a released state, so that both sides of the bobbin Bw, which is supported from below by the front end support part 65, in the machine machine longitudinal direction are , the restriction by the arm portion 62b is released (see FIG. 7). In this state, the bobbin holder 70 is closed inward in the machine machine longitudinal direction from both sides of the bobbin Bw in the machine machine longitudinal direction with respect to the hollow portion of the cylindrical bobbin Bw, so that 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 to the standby position. As the stocker 60 moves from the supply position to the standby position, it moves away from the cradle arm 30 in the release position toward the other side in the machine width direction. As a result, the regulating portion 62, which is in contact with the bobbin holder 70 supported by the cradle arm 30 with the contact portion 62c in the release position, rotates in the second direction opposite to the first direction D1 about the rotation shaft 66. and switches from the released state to the restricted state. Then, by releasing the contact between the contact portion 62c and the bobbin holder 70, the regulating portion 62 returns to the regulating state due to the biasing force of the biasing member 67.

Further, 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 when the stocker 60 moves from the supply position to the standby position. As a result, the front end support portion 65 rotates about the rotating shaft 66 against the biasing force of the biasing member 67 so as to avoid the bobbin Bw. In other words, the front end support portion 65 rotates about the rotating shaft 66 against the biasing force of the biasing member 67 such that the distal end portion is located below the base end portion connected to the rotating shaft 66 . Then, when the stocker 60 further moves toward the standby position and the front end support part 65 and the bobbin Bw are no longer in contact with each other, the front end support part 65 is urged by the urging member 67 and returns to the regulating position. Note that 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. Of the plurality of bobbins Bw remaining in the stocker 60, the bobbin Bw closest to one side in the machine width direction is supported from below by the front end support portion 65 which has returned to the regulating position.

Through the above operations, 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 section 50 disposed on one side of the vertical plane F, a stocker 60 disposed on the other side of the vertical plane F, and a stocker 60 on standby. It includes a moving mechanism 80 that moves between the position and the supply position. The moving mechanism 80 linearly moves the stocker 60 between a standby position and a supply position. According to this, while the stocker 60 moves 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 it is necessary to secure a separate space above the winding device 21. There is no. However, even when moving the stocker 60 linearly, for example, if the stocker 60 is arranged above the package storage section 50 as in Patent Document 2 mentioned above, the position of the stocker 60 will be high, and the winding There is a limit to the reduction in the height of the removing device 21. This is because the winding package Pw released from the cradle arm 30 passes below the stocker 60 and is sent to the package storage section 50, so the winding package Pw passes through the distance between the stocker 60 and the package storage section 50. This is because it is necessary to make it as large as possible. In this regard, in this embodiment, the stocker 60 is arranged on the opposite side of the package storage section 50 with the vertical plane F as the boundary. Therefore, while the stocker 60 is arranged at a low position, it is possible to prevent the stocker 60 from passing through a position above both the standby position and the supply position, thereby effectively suppressing the height of the winding device 21. can do.

In the winding device 21 of this embodiment, the stocker 60 is provided with a regulating section 62 that can be switched between a regulating state and a releasing state. The regulating portion 62 is in a released state when the stocker 60 reaches the supply position. According to this, the bobbin Bw can be prevented from falling off from the stocker 60 by the regulating portion 62 in the regulating state until the stocker 60 reaches the supply position. Further, since the regulating portion 62 is in the released state when the stocker 60 reaches the supply position, the regulating portion 62 does not inhibit the supply of the bobbin Bw from the stocker 60 to the cradle arm 30. Thereby, the bobbin Bw can be appropriately supplied from the stocker 60 to the cradle arm 30 while the bobbin Bw can be reliably stored by the stocker 60.

In the winding device 21 of this embodiment, the regulating portion 62 has a contact portion 62c that can come into contact with the bobbin holder 70 supported by the cradle arm 30 in the release position. As the stocker 60 moves from the standby position to the supply position, the abutting portion 62c of the regulating portion 62 is pushed by the bobbin holder 70, so that the regulating portion 62 rotates in the first direction D1 around the rotating shaft 66 and enters the regulating state. It switches to the released state. Further, as the stocker 60 moves from the supply position to the standby position, the contact portion 62c and the bobbin holder 70 are released from contact, so that the regulating portion 62 is moved in the first direction D1 around the rotating shaft 66. The release state is switched from the release state to the restriction state by rotating in a second direction opposite to the above. According to this, depending on whether or not the contact portion 62c and the bobbin holder 70 come into contact with each other as the stocker 60 moves, the restricting portion 62 can be switched between the released state and the restricted state. Therefore, a drive source for switching the state of the regulating portion 62 is not required.

In the winding device 21 of this embodiment, the stocker 60 has a stopper 63 that can be contacted by a regulating portion 62 that rotates in the first direction D1. When the stocker 60 reaches the supply position, the regulating portion 62 rotates in the first direction D1 when the contact portion 62c is pushed by the bobbin holder 70, and further rotates in the first direction D1 by contacting the stopper 63. is regulated. According to this, further pushing of the abutting portion 62c of the regulating portion 62 by the bobbin holder 70 is regulated, that is, further movement of the stocker 60 is regulated. Thereby, it is possible to prevent the stocker 60 from further moving beyond the supply position, and the bobbin Bw can be appropriately supplied from the stocker 60 to the cradle arm 30.

Further, in the winding device 21 of the present embodiment, when the stocker 60 reaches the supply position and the regulating portion 62 is in the released state, the bobbin Bw stored in the stocker 60 does not jump out beyond the bobbin holder 70. The stocker 60 is provided with a second restricting portion 64 that suppresses the amount of water. 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 tends to move beyond the cradle arm 30 in the release position along the direction in which the stocker 60 moves. However, when the stocker 60 reaches the supply position, the regulating portion 62 is in a released state, and therefore cannot regulate the movement of the bobbin Bw. Therefore, there is a possibility that the bobbin Bw stored in the stocker 60 may move beyond the cradle arm 30. In this case, the bobbin Bw cannot be properly supplied 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, the bobbin Bw is prevented from moving beyond the cradle arm 30 in the release position due to inertia force. can be suppressed. Thereby, the bobbin Bw can be more reliably supplied from the stocker 60 to the cradle arm 30.

In the winding device 21 of this embodiment, a front end support part 65 that supports the bobbin Bw from below is provided at the front end of the stocker 60 near the cradle arm 30 in the release position. The front end support portion 65 is capable of taking a regulating posture that prevents the bobbin Bw from falling off from the stocker 60, and is rotatable about the rotation shaft 66. Furthermore, the stocker 60 further includes a biasing member 67 that biases the front end support portion 65 to take the regulating posture. When the stocker 60 moves from the supply position to the standby position, the front end support part 65 is pushed by the bobbin Bw supported by the cradle arm 30 in the release position, and rotates against the biasing force of the biasing member 67. It rotates around the shaft 66 so as to avoid the bobbin. In this embodiment, the provision of the front end support portion 65 prevents the bobbin Bw stored in the stocker 60 from falling off from the stocker 60. On the other hand, when the stocker 60 attempts to return to the standby position after the supply of the bobbin Bw from the stocker 60 to the cradle arm 30 is completed, a front end support part 65 that attempts to prevent the bobbin Bw from falling off, and a front end support part 65 that is supported by the cradle. There is a possibility that the bobbin Bw may get caught and the movement of the stocker 60 may be hindered. According to this embodiment, when the stocker 60 returns from the supply position to the standby position, the front end support part 65 rotates so as to avoid the bobbin Bw supported by the cradle arm 30. Therefore, it is possible to avoid the front end support portion 65 and the bobbin Bw supported by the cradle arm 30 from getting caught and preventing the stocker 60 from moving to the standby position. 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 subsequent winding operation of the thread Y can be performed promptly.

(Modified example)
Below, a modification of the above embodiment will be described. However, components having the same configuration as those in the embodiment described above will be designated by the same reference numerals and the description thereof will be omitted as appropriate.

In the embodiment described above, the regulating portion 62 is configured to switch from the regulating state to the releasing state when the abutting portion 62c is pushed by the bobbin holder 70 as the stocker 60 moves from the standby position to the supply position. However, the restriction section 62 that can be switched between the restriction state and the release state is not limited to the above configuration. For example, the restriction portion 62 may be switchable between a restriction state and a release state by a transmission motor.

Further, in the embodiment described above, the restriction portion 62 can be switched between the restriction state and the release state by rotating around the rotation shaft 66. However, the restricting portion 62 is not limited to a configuration in which it rotates around the rotating shaft 66. For example, the restricting portion 62 may be configured to be switchable between a restricted state and a released state by sliding in a direction intersecting the extending direction of the stocker 60.

In the embodiment described above, the stocker 60 in the standby position is located in a direction that substantially matches the extending direction of the stocker 60, and in a diagonal direction downward and on one side in the machine width direction (diagonally lower left of the page in FIG. 3). move in a straight line in a direction). However, the stocker 60 in the standby position does not move linearly to one side in the width direction of the machine and in an upward diagonal direction (for example, diagonally upward to the left of the page in FIG. 3) or in a horizontal direction. good. In this case, a push-out mechanism or the like for pushing out the bobbin Bw stored in the stocker 60 from the rear end of the stocker 60 toward the front end in the extending direction is arranged in the stocker 60. Furthermore, the direction in which the stocker 60 extends and the direction in which the stocker 60 moves linearly may not substantially match.

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

In the embodiment described above, the stocker 60 has a regulating section 62 that can be switched between a regulating state and a releasing state. However, the stocker 60 does not need to have the restriction part 62. In this case, the stocker 60 may be provided with a member for preventing the bobbin Bw from falling off from the stocker 60 at the standby position and from the stocker 60 moving from the standby position toward the supply position. preferable.

In the embodiment described above, the stocker 60 has a second regulating part 64 that prevents the bobbin Bw stored in the stocker 60 from jumping out beyond the bobbin holder 70 when the regulating part 62 is in the released state. . However, the stocker 60 does not need to have the second restriction part 64. In this case, it is preferable that the moving mechanism 80 sets the moving speed of the stocker 60 from the standby position to the supply position to a predetermined rough speed or less. The predetermined speed is a speed that can prevent the bobbin Bw from jumping out beyond the bobbin holder 70 from the stocker 60 that has reached the supply position. 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 prevented from falling off from the stocker 60.

In the embodiment described above, two of the second regulating portions 64 are located on both sides of the central portion of the stocker 60 in the longitudinal direction of the machine and on the inner side of the two regulating portions 62 . However, the number of second regulating portions 64 is not limited to two. For example, one second regulating portion 64 may be disposed, or three or more second regulating portions 64 may be disposed.

In the embodiment described above, the stocker 60 has a front end support portion 65. However, the stocker 60 does not need to have the front end support part 65. In this case, it is preferable that the stocker 60 is provided with a regulating section 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 applicable not only to the false twisting machine 1 but also to a winding device of a rewinder.

In the embodiment described above, the cradle arm 30 is configured to be movable between the winding position and the release position. However, the cradle arm does not have to move between the winding position and the release position, for example, if the contact roller 40 is not of the line drive type where the contact rollers 40 are connected to a common drive shaft for multiple spindles, A fixed cradle arm may be used (see Japanese Patent Laid-Open No. 2015-40116, etc.). In this case, the winding position and release position of the cradle arm are the same position.

According to the present invention, the restriction portion that rotates in the first direction as the stocker moves is restricted from further rotation in the first direction by coming into contact with the stopper. Therefore, the bobbin holder restricts further pushing of the abutting portion of the restricting portion, that is, further movement of the stocker is restricted. Thereby, it is possible to prevent the stocker from further moving beyond the supply position, and it is possible to appropriately supply the bobbin from the stocker to the cradle.

In the winding device of the present invention, a front end support part for supporting the bobbin from below is provided at a front end part of the stocker near the cradle in the release position, and the front end support part supports the bobbin from below. The stocker is capable of taking a restricting posture that prevents the bobbin from falling off from the stocker, and is rotatable about a second rotation axis along the axial direction of the bobbin holder, and the stocker is arranged so that the front end The front end support part further includes a biasing member that biases the support part to take the regulating position, and the front end support part is configured to support the cradle in the release position when the stocker moves from the supply position to the standby position. By being pushed by the bobbin supported by the bobbin, it is preferable to rotate about the second rotation axis so as to avoid the bobbin, against the urging by the urging member.

The moving mechanism 80 is for linearly moving the stocker 60 between the standby position and the supply position. The standby position is a position where the stocker 60 is 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 being wound around the bobbin Bw supported by the cradle arm 30, or when the winding package Pw is released from the cradle arm 30 in the release position and the package storage section 50 is in the standby position. This is the position where the stocker 60 is on standby when the food is being sent to the warehouse. Stocker 60 in the standby position can avoid contact with bobbin Bw or winding package Pw supported by cradle arm 30. As shown in FIG. 3, the stocker 60 in the standby position is placed on the other side of the vertical plane F. The supply position is the 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 from which the bobbin Bw on which the winding package Pw has been formed has been removed. (See Figure 4). As shown in FIG. 4, when the stocker 60 is in the supply position, the axis of the bobbin Bw closest to one side in the machine width direction among the plurality of bobbins Bw stored in the stocker 60 is in the release position. The axis of the bobbin holder 70 supported by the cradle arm 30 coincides with the axis of the bobbin holder 70 .

The stopper 63 is a portion that can be abutted by the regulating portion 62 that rotates in the first direction D1. Specifically, the stopper 63 is a portion that can be contacted by the other side and upper portion of the arm portion 62b in the machine width direction (see FIG. 7) . The stoppers 63 are arranged to face each other in the longitudinal direction of the machine. The stopper 63 is formed on the top of the stocker 60. More specifically, when four bobbins Bw are stored in the stocker 60, if the first to fourth bobbins Bw are placed in order from the bobbin Bw on one side in the machine width direction, the top of the second bobbin Bw is A stopper 63 is formed at the portion. As shown in FIGS. 4 and 7, when the stocker 60 reaches the supply position, the regulating part 62 rotating in the first direction D1 comes into contact with the stopper 63, so that the regulating part 62 further rotates in the first direction D1. rotation is regulated.

The front end support portion 65 supports from below the bobbin Bw that is closest to one side in the machine width direction among the plurality of bobbins Bw stored in the stocker 60 . As shown in FIGS. 2 and 5, the front end support portion 65 is provided at the front end and lower portion of the stocker 60 near the cradle arm 30 in the released position. Further, as shown in FIG. 5, the front end support portion 65 extends in the longitudinal direction of the machine base. Furthermore, as shown in FIGS. 6 and 7, when viewed from the longitudinal direction of the machine, one side of the front end support portion 65 in the width direction of the machine has a V-shaped bend. The front end support portion 65 is made of, for example, sheet metal or resin.

While the stocker 60 is moving from the standby position to the supply position, the contact portion 62c contacts the bobbin holder 70 supported by the cradle arm 30 in the release position. More specifically, in FIGS. 3 and 4, the abutting portion 62c of the regulating portion 62 located on the back side of the paper in the longitudinal direction of the machine base is connected to the bobbin holder 70 located on the back side of the paper in the longitudinal direction of the machine machine. The abutting portion 62c of the regulating portion 62 disposed on the front side of the paper in the longitudinal direction of the machine base contacts the bobbin holder 70 disposed on the front side of the paper in the longitudinal direction of the machine base. As the stocker 60 further moves to the supply position from the state where the contact portion 62c and the bobbin holder 70 are in contact, the contact portion 62c is pushed by the bobbin holder 70. As a result, the regulating portion 62 of the stocker 60 rotates in the first direction D1 (see FIG. 6) about the rotating shaft 66 and switches from the regulating state to the releasing state. Then, when the stocker 60 reaches the supply position, the regulating portion 62 is in the released state (see FIGS. 4 and 7). Note that in FIGS. 6 and 7, for the sake of explanation, the cradle arm 30 and bobbin holder 70 on the front side in the longitudinal direction of the machine frame are omitted.

In the winding device 21 of this embodiment, a front end support part 65 that supports the bobbin Bw from below is provided at the front end of the stocker 60 near the cradle arm 30 in the release position. The front end support portion 65 is capable of taking a regulating posture that prevents the bobbin Bw from falling off from the stocker 60, and is rotatable about the rotation shaft 66. Furthermore, the stocker 60 further includes a biasing member 67 that biases the front end support portion 65 to take the regulating posture. When the stocker 60 moves from the supply position to the standby position, the front end support part 65 is pushed by the bobbin Bw supported by the cradle arm 30 in the release position, and rotates against the biasing force of the biasing member 67. It rotates around the shaft 66 so as to avoid the bobbin. In this embodiment, the provision of the front end support portion 65 prevents the bobbin Bw stored in the stocker 60 from falling off from the stocker 60. On the other hand, when the stocker 60 attempts 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 front end support part 65 that tries to prevent the bobbin Bw from falling off and the support part 65 that is supported by the cradle arm 30 There is a possibility that the moved bobbin Bw may get caught and the movement of the stocker 60 may be hindered. According to this embodiment, when the stocker 60 returns from the supply position to the standby position, the front end support part 65 rotates so as to avoid the bobbin Bw supported by the cradle arm 30. Therefore, it is possible to avoid the front end support portion 65 and the bobbin Bw supported by the cradle arm 30 from getting caught and preventing the stocker 60 from moving to the standby position. 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 subsequent winding operation of the thread Y can be performed promptly.

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

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

In the embodiment described above, the cradle arm 30 is configured to be movable between the winding position and the release position. However, the cradle arm 30 does not have to move between the take-up position and the release position, for example, if the contact roller 40 is not of the line drive type where the contact rollers 40 are connected to a common drive shaft for multiple spindles. , a fixed cradle arm may be used (see Japanese Patent Laid-Open No. 2015-40116, etc.). In this case, the winding position and release position of the cradle arm are the same position.
