Description

The present invention primarily relates to a yarn winding machine that produces packages by winding multiple yarns fed from a yarn feed roller onto multiple bobbins.

The yarn winding machine disclosed in Patent Document 1 includes a traverse device and first and second bobbin holders. The traverse device traverses multiple yarns supplied from a godet roller (yarn feed roller). Multiple bobbins are attached to each of the first and second bobbin holders. The yarn winding machine produces packages by winding yarn onto the multiple bobbins in the first bobbin holder, and when package production is complete (a full package is produced), it switches the yarn winding target to the multiple bobbins in the second bobbin holder.

Furthermore, the axial length of the godet roller disclosed in Patent Document 1 is shorter than the axial length of the bobbin holder. Therefore, the spacing between the multiple yarns traveling from the godet roller to the bobbin holder increases as they move downstream. Therefore, when multiple yarns are removed from the traverse device during bobbin switching, the spacing between the yarns narrows and they move toward the center. To solve this problem, the yarn winding machine in Patent Document 1 is equipped with a yarn path changing member. The yarn path changing member restricts the movement of each yarn to prevent the spacing between the yarns from narrowing when multiple yarns are removed from the traverse device.

Japanese Patent Application Laid-Open No. 2003-226469

The yarn winding machine of Patent Document 1 prevents the spacing between yarns from narrowing when multiple yarns are removed from the traverse device. However, depending on the device conditions or winding conditions, the spacing between yarns may widen when multiple yarns are removed from the traverse device. For example, if the axial length of the yarn feed roller is longer than the bobbin holder, this situation may occur when multiple yarns are initially wound around multiple bobbins in the bobbin holder. As a result, the multiple yarns spread out over an area wider than the bobbin mounting area of the bobbin holder, making it difficult to wind the multiple yarns around the multiple bobbins in the bobbin holder. Furthermore, the spreading of the multiple yarns can cause the yarns to fall outside the axial direction of the bobbin during winding, which can result in yarn breakage.

The present invention was made in consideration of the above circumstances, and its main purpose is to provide a yarn winding machine that makes it easy to wind the yarn onto the bobbin holder by preventing the yarn from spreading over an area wider than the axial area of the multiple bobbins held in the bobbin holder when the yarn is released from the traverse device, and that also prevents yarn breakage due to yarn falling.

Means to solve the problem and effects

The problem that this invention aims to solve is as described above. Next, we will explain the means for solving this problem and its effects.

According to an aspect of the present invention, there is provided a yarn winding machine having the following configuration. Specifically, the yarn winding machine produces a package by winding multiple yarns, which are fed from a yarn feed roller, onto multiple bobbins, respectively. The yarn winding machine includes a bobbin holder, multiple traverse guides, a yarn release state maintenance guide, a regulating guide, and a movement mechanism. The bobbin holder holds the multiple bobbins. The traverse guides contact the multiple yarns and traverse the yarns in the bobbin holder axial direction. The yarn release state maintenance guides contact the multiple yarns to maintain a state in which the multiple yarns are released from the multiple traverse guides. Two regulating guides are provided, and they regulating the multiple yarns within a regulating range that is inside the axial region of the multiple bobbins held in the bobbin holder so that the positions of the multiple yarns held by the yarn release state maintenance guides in the bobbin holder axial direction are inside the axial region of the multiple bobbins held in the bobbin holder. The moving mechanism is capable of moving the two restriction guides between a restriction position where the two restriction guides act on the plurality of yarns to restrict the plurality of yarns and a retracted position where the two restriction guides are retracted from the restriction position. The yarn release state maintenance guide is capable of moving between a holding position where the two restriction guides hold the plurality of yarns and a retracted position where the two restriction guides are retracted from the holding position. The portions of the two restriction guides that are attached to the moving mechanism are referred to as attachment portions, and the portions that act on the yarns are referred to as action portions. When a height direction is a direction in which the yarn feed roller is located with respect to the yarn winding machine, and a direction orthogonal to both the height direction and the bobbin holder axial direction is referred to as an axial-orthogonal direction, the action portions are located closer to the yarn path than the attachment portions in the axial-orthogonal direction at both the restriction position and the retracted position.

As a result, the restricting guide restricts the yarn to within the axial region of the bobbin, preventing the yarn from spreading when the yarn is removed from the traverse device. This makes it easier to thread the yarn onto the bobbin holder. Furthermore, when the yarn no longer needs to be restricted, the restricting guide can simply be moved to the retracted position, making it easier to handle compared to configurations that require attachment and detachment. Furthermore, the restricting guide can be moved between the restricting position and the retracted position without significantly changing its orientation. This reduces the trajectory of the restricting guide's movement, allowing for more space to be used for other components. Furthermore, preventing the yarn from spreading when the yarn is removed from the traverse device reduces the likelihood of yarn dropout. As a result, yarn breakage due to yarn dropout can be reduced.

In the yarn winding machine, the movement mechanism preferably includes a mechanism for sliding the two restriction guides in the axial direction of the bobbin holder at least inside an axial region of the plurality of bobbins.

During threading, the restriction guide can be slid from its restricted position to disperse the winding position of the yarn restricted by the restriction guide.

In the yarn winding machine, it is preferable that the two regulating guides slide in the axial direction of the bobbin holder, thereby switching between the regulating position and the retracted position of the two regulating guides.

This allows for easy switching between the restricted position and the retracted position with a small movement trajectory.

In the above-mentioned yarn winding machine, it is preferable that an operating unit is provided which is arranged at the end side of the two regulating guides in the axial direction of the bobbin holder and is connected to the two regulating guides, and which can be operated to slide the two regulating guides.

This makes it easier to slide the restriction guide compared to touching it directly.

In the yarn winding machine, it is preferable that the two regulating guides are switched from the regulating position to the retracted position by the action portion moving in the height direction in a direction away from the yarn feed roller.

This makes it less likely to interfere with the operation of other devices.

The yarn winding machine preferably has the following configuration. That is, the movement mechanism includes a support rail that is provided along the bobbin holder axial direction and supports the two regulating guides so that the two regulating guides maintain the regulating positions. The two regulating guides are slidable along the support rail in the bobbin holder axial direction. The two regulating guides are switched from the regulating positions to the retracted position by sliding past the location of the support rail.

This allows the component that assists sliding and the component that maintains the restriction guide in the restriction position to be the same. It also makes it easy to switch from the restriction position to the retracted position.

The yarn winding machine preferably has the following configuration. That is, the movement mechanism includes two connecting members and a support shaft member. The two connecting members are attached to the two regulating guides, respectively. The support shaft member supports the two connecting members, and the two connecting members are rotatably connected. At the regulating position, the two connecting members extend from the support shaft member toward the yarn path in the direction perpendicular to the axis. At the retracted position, the two connecting members extend from the support shaft member to the side opposite the yarn path in the direction perpendicular to the axis.

This allows the movement trajectory of the restriction guide to be smaller compared to a configuration in which the restriction guide itself is inverted.

The above-described yarn winding machine is preferably configured as follows: That is, the yarn winding machine includes a first housing and a second housing. The traverse guide is disposed in the first housing. The second housing is disposed opposite the first housing with the yarn path interposed therebetween. The yarn removal state maintaining guide is disposed in the first housing. The two restriction guides are disposed in the second housing.

This allows the yarn removal state maintaining guide and the restriction guide to be suitably arranged.

The above-mentioned yarn winding machine preferably has the following configuration: a yarn splitting guide that separates multiple yarns and holds them in the traverse regions of the multiple traverse guides. The yarn splitting guide is movable between a yarn splitting position where it separates and holds multiple yarns, and a retracted position where it is retracted from the yarn splitting position.

This allows multiple threads to be regulated by the regulation guides while each thread is guided into the traverse area of each traverse guide and brought into contact (engagement) with each traverse guide, making threading easier.

In the above-described yarn winding machine, it is preferable that the axial length of the bobbin holder is smaller than the axial length of the yarn feed roller, and the pitch between the multiple yarns on the bobbin holder is smaller than the pitch between the multiple yarns on the yarn feed roller.

If the pitch between the multiple threads on the bobbin holder is smaller than the pitch between the multiple threads on the yarn feed roller, the multiple threads tend to spread out over a wider area than the axial area of the multiple bobbins held in the bobbin holder, so the effect of providing the above-mentioned regulating guide can be effectively exerted.
In the yarn winding machine, it is preferable that the two regulating guides are arranged on the upper surface of a housing to which a contact roller that contacts the yarn layers of the package with a predetermined pressure is rotatably mounted when winding the multiple yarns.

Next, an embodiment of the present invention will be described with reference to the drawings. Figure 1 is a front view of a yarn winding machine 1 according to a first embodiment. Figure 2 is a block diagram of the yarn winding machine 1. In the following description, the upstream and downstream sides of the yarn running direction may be simply referred to as upstream and downstream.

A spinning machine (not shown) is located upstream of the yarn winding machine 1 shown in Figure 1. Yarn 91 produced by the spinning machine is supplied to the yarn winding machine 1 via a yarn feed roller 100. The yarn winding machine 1 winds the yarn 91 onto a bobbin 90 to form a yarn layer on the bobbin 90 and produce a package 92. The yarn 91 is, for example, an elastic yarn such as spandex. However, the type of yarn 91 is not limited to this and may also be a synthetic yarn such as nylon or polyester.

As shown in FIG. 1, the yarn winding machine 1 has two winding units 10 arranged one above the other. A yarn 91 is supplied to each winding unit 10, and a package 92 is produced in each winding unit 10. A plurality of yarns 91 arranged in the axial direction of the package 92 are supplied to the winding unit 10. Each winding unit 10 winds the plurality of yarns 91 to produce a plurality of packages 92.

Since the two winding units 10 each have the same devices, the upper and lower winding units 10 will be described together below. As shown in Figure 1, the winding unit 10 includes a frame 11, a first housing 20, a second housing 30, and a turret plate 40.

The frame 11 is a member that holds the various components of the winding unit 10. A traverse device 21 is attached to the first housing 20. The traverse device 21 traverses the yarn 91 being fed downstream by reciprocating in the winding width direction (axial direction of the package 92) with a traverse guide 23 (described below) engaged with the yarn 91. As shown in Figure 2, the traverse device 21 includes a traverse cam 22, a traverse guide 23, and a traverse motor 24. Note that Figure 2 shows a block diagram of one winding unit 10.

The traverse cam 22 is a roller-shaped member arranged parallel to the bobbin 90. A spiral cam groove is formed on the outer peripheral surface of the traverse cam 22. The traverse cam 22 is driven to rotate by a traverse motor 24.

The traverse guide 23 is the part that engages with the thread 91. The tip of the traverse guide 23 has, for example, a roughly U-shaped guide portion, which engages with the thread 91 by pinching it in the winding width direction. The base end of the traverse guide 23 is located in the cam groove of the traverse cam 22. By rotating the traverse cam 22, the traverse guide 23 can be moved back and forth in the winding width direction.

The traverse motor 24 is also controlled by a control device 50. The control device 50 includes a CPU, ROM, RAM, etc. The CPU reads programs stored in the ROM into the RAM and executes them, thereby performing various controls related to the winding unit 10.

A contact roller 31 is rotatably attached to the second housing 30. When winding the yarn 91, the contact roller 31 rotates while contacting the yarn layer of the package 92 with a predetermined pressure, thereby adjusting the shape of the yarn layer of the package 92.

The second housing 30 is provided with an operation panel 32. The operation panel 32 is a device operated by an operator. The operator operates the operation panel 32 to issue instructions to the winding unit 10. Instructions issued by the operator include, for example, starting winding, stopping winding, and changing winding conditions.

The turret plate 40 is a disk-shaped member. The turret plate 40 is rotatably attached to the frame 11. The position of the rotation axis of the turret plate 40 coincides with the center position of the turret plate 40. The turret plate 40 is driven to rotate by a turret motor 41 shown in Figure 2. The turret motor 41 is controlled by the control device 50.

A bobbin holder 42 is provided at each of two locations on the turret plate 40, facing each other across the center position. A number of bobbins 90 can be attached to the bobbin holders 42, arranged in the axial direction. The positions of the two bobbin holders 42 can be changed by rotating the turret plate 40. Each bobbin holder 42 is supported in a cantilevered manner by the turret plate 40.

The bobbin holder 42 is rotatable relative to the turret plate 40, with the axis of the bobbin holder 42 serving as the center of rotation. The two bobbin holders 42 are individually driven and rotated by bobbin holder motors 43 shown in Figure 2. The bobbin holder motors 43 are controlled by the control device 50.

With two bobbin holders 42 lined up one above the other, thread 91 is wound onto the higher bobbin holder 42. Specifically, after threading is performed on the bobbin 90 of one bobbin holder 42, the other bobbin holder 42 comes into contact with the contact roller 31. As the other bobbin holder 42 rotates in this state, thread 91 is wound onto the bobbin 90 of the other bobbin holder 42, producing a package 92. A tip support member 45 (Figure 1) is provided for supporting the free end of the bobbin holder 42 when the bobbin holder 42 is in contact with the contact roller 31.

Furthermore, when a predetermined amount of yarn 91 is wound onto the package 92 and it becomes full, the turret plate 40 rotates, switching the positions of the two bobbin holders 42. The full package 92 is then collected, while the yarn 91 is wound onto the bobbin 90 attached to one of the bobbin holders 42.

Next, in the preliminary stage of manufacturing the package 92, an operator performs a threading operation in which the thread 91 is wound around the bobbin 90 of one of the two bobbin holders 42, followed by a waste winding operation. This threading operation and waste winding operation will now be described. In this embodiment, the winding width direction, the axial direction of the package 92, and the axial direction of the bobbin holder 42 (bobbin holder axial direction) are all parallel. In the following description, these directions will be collectively referred to as the "axial direction." Furthermore, the direction in which the yarn feed roller 100 is located relative to the yarn winding machine 1 will be referred to as the "height direction." In particular, the side of the height direction closer to the yarn feed roller 100 will be referred to as the upper side, and the opposite side will be referred to as the lower side. Furthermore, the direction perpendicular to both the axial and height directions will be referred to as the "axial-orthogonal direction."

When the operator threads the yarn 91, the yarn 91 is wound without being engaged with the traverse guide 23. The traverse guide 23 also drives at a slower speed than normal. Therefore, even if the yarn 91 engages with the traverse guide 23 after threading, the quality of the yarn 91 cannot be ensured until the traverse guide 23 reaches its normal speed. Therefore, it is necessary to wind the low-quality yarn 91 by performing a waste winding and discard the wound yarn 91.

In this embodiment, the axial length of the bobbin holder 42 (the length indicated by reference symbol L2 in FIG. 3 ) is smaller than the axial length of the yarn feed roller 100 (the length indicated by reference symbol L1 in FIG. 3 ). Therefore, the pitch between the yarns on the bobbin holder 42 is smaller than the pitch between the yarns on the yarn feed roller 100. When performing the tail winding under these conditions, the following situation may occur. That is, when the yarn 91 is wound from the yarn feed roller 100 onto the bobbin 90, the yarn 91 located at the axial end of the yarn feed roller 100 may fall off to the axial outside of the bobbin 90 located at the axial end, resulting in yarn breakage. Even if no yarn fall occurs, multiple yarns 91 may be concentrated at the axial end of the bobbin 90, as shown in FIG. 4 . As a result, localized thickening occurs at the axial end during tail winding, which may cause the yarn layer to collapse and lead to yarn breakage.

To prevent yarn breakage due to yarn drop and localized thickening of the winding, the yarn winding machine 1 of this embodiment is equipped with a restricting guide 60a and a moving mechanism 70a. The range over which the restricting guide 60a restricts the position of the yarn 91 is referred to as the restricting range (the length indicated by the symbol L3 in FIG. 3). The restricting range is inside the axial area of the multiple bobbins 90 (the area where the multiple bobbins 90 are attached to the bobbin holder 42). In this embodiment, the restricting guide 60a and the moving mechanism 70a are located on the top surface of the second housing 30. However, the restricting guide 60a and the moving mechanism 70a may be located in other positions where they can restrict the yarn 91.

The configuration of the restriction guide 60a and movement mechanism 70a will be explained below with reference to Figures 3 and 5.

The restricting guides 60a are provided at both ends in the axial direction. One restricting guide 60a restricts one or more threads 91 at one axial end, and the other restricting guide 60a restricts one or more threads 91 at the other axial end. The two restricting guides 60a are symmetrical across a plane perpendicular to the axial direction, so the two restricting guides 60a will be described together below.

The restricting guide 60a is a member that acts directly on (contacts) the thread 91 to restrict the thread 91. The restricting guide 60a is a member manufactured by performing processes such as punching and bending on a plate material. However, the restricting guide 60a may also be configured to be manufactured by attaching multiple members.

As shown in Figures 3 and 5, the restriction guide 60a includes an attachment portion 61, a midway portion 62, and an action portion 63. The attachment portion 61 is the portion that is attached to the movement mechanism 70a. Specifically, the attachment portion 61 is a portion in which a through hole is formed. The midway portion 62 is a portion formed between the attachment portion 61 and the action portion 63. The action portion 63 is inclined relative to the midway portion 62 and is the portion that comes into contact with the thread 91.

A moving mechanism 70a is provided at each end in the axial direction. The two moving mechanisms 70a are symmetrical across a plane perpendicular to the axial direction, so the following description will focus on both moving mechanisms 70a. As shown in Figures 3 and 5, the moving mechanism 70a includes a slide rail (support shaft member) 71 and a support rail 72.

The slide rail 71 is a cylindrical member arranged along the axial direction. The slide rail 71 is inserted through a through-hole in the mounting portion 61. This allows the restricting guide 60a to slide along the slide rail 71. Furthermore, because the cross section of the slide rail 71 is circular, the restricting guide 60a can rotate around the slide rail 71 as the center of rotation. In the yarn winding machine 1 of this embodiment, the operator manually slides or rotates the restricting guide 60a. Alternatively, an actuator may be provided to drive the restricting guide 60a. In this embodiment, the slide rail 71 is a member that functions as both a rail that slides the restricting guide 60a and a rotation shaft (support shaft member) that supports and rotates the restricting guide 60a. Alternatively, the member that functions as the rail and the member that functions as the rotation shaft may be separate members.

The support rail 72 is located closer to the first housing 20 than the slide rail 71. Like the slide rail 71, the support rail 72 is arranged along the axial direction. By supporting the midpoint 62, the support rail 72 restricts the downward rotation of the restricting guide 60a (in other words, the downward movement of the acting portion 63), as shown in the upper diagram of Figure 5. This allows the restricting guide 60a to be maintained in the restricting position. The restricting position is the position where the restricting guide 60a restricts the thread 91. The restricting position of the restricting guide 60a can be changed in the axial direction by sliding in the axial direction with the midpoint 62 supported by the support rail 72.

Furthermore, the support rails 72 are not formed near the axial ends. In other words, the movement mechanism 70a has a range where the slide rails 71 are formed but no support rails 72 are formed. In other words, when the restricting guide 60a slides beyond the point where the support rails 72 are located and into the range where the support rails 72 are not formed, the midpoint 62 is no longer supported by the support rails 72, and the restricting guide 60a rotates downward (the acting portion 63 moves downward). This causes the restricting guide 60a to move to the retracted position. The retracted position is a position retracted from the restricting position and is a position where the yarn 91 is not restricted (where it does not interfere with the yarn path).

In this embodiment, the restricting guide 60a retracts axially outward from the yarn path by sliding toward the end in the axial direction, and also retracts from the yarn path by rotating downward. In other words, in both the restricting position and the retracted position, the acting portion 63 of the restricting guide 60a in this embodiment is located closer to the yarn path in the direction perpendicular to the axis than the mounting portion 61.

This configuration allows the movement trajectory of the restricting guide 60a to be small. Specifically, if the restricting guide 60a is rotated upward by 180 degrees or more to be retracted (i.e., if the mounting portion 61 is positioned closer to the yarn path than the acting portion 63), the movement trajectory of the restricting guide 60a becomes large. As a result, a large space must be left above the restricting guide 60a.

In contrast, in this embodiment, the movement trajectory of the restricting guide 60a does not include the space above the restricting guide 60a. This allows this space to be used effectively. As shown in Figure 6, in this embodiment, an oil drip tray 12 is placed in this space. The oil drip tray 12 is a component that protects the first housing 20, the second housing 30, and the yarn path between them from getting oil on them. Note that components other than the oil drip tray 12 may also be placed in this space.

Even if an axial force is applied to the restricting guide 60a due to vibration or other reasons, the intermediate portion 62 interferes with the end face of the support rail 72, preventing it from returning to the restricting position. In this way, the support rail 72 has both the function of maintaining the restricting guide 60a in the restricting position and the function of maintaining the restricting guide 60a in the retracted position. In this embodiment, the restricting guide 60a can be retracted from the yarn path simply by sliding it axially, so the mechanism for rotating the restricting guide 60a downward to retract it is not essential and can be omitted. Furthermore, although the restricting guide 60a in this embodiment is a component used during the extra winding process, it can also be used in other situations where yarn dropouts may occur (for example, when threading the yarn 91 onto the bobbin 90).

Next, with reference to Figures 6 and 7, we will explain the opening and closing guide 80, which is used for the extra winding together with the restricting guide 60a and the moving mechanism 70a.

The opening/closing guide 80 is disposed on the upper surface of the first housing 20. In other words, when viewed in the direction perpendicular to the axis, the opening/closing guide 80 and the restriction guide 60a are disposed so as to face each other with the yarn path interposed therebetween. As shown in Fig. 7, the opening/closing guide 80 includes an opening/closing plate 81, a cylindrical member 82, a rail 83, a yarn removal guide (a guide for maintaining the yarn removal state) 84, a yarn split guide 85, and a gripping portion 86.

The opening/closing plate 81 is a long, narrow flat plate, and is arranged so that its longitudinal direction and axial direction coincide. A cylindrical member 82 is immovably fixed to the short end of the opening/closing plate 81. A through hole is formed in the cylindrical member 82.

The rail 83 is a cylindrical member arranged along the axial direction. The rail 83 passes through a through-hole in the tubular member 82. This allows the tubular member 82 to slide along the rail 83. Because the tubular member 82 is fixed to the opening/closing plate 81, the opening/closing plate 81 can slide axially along the rail 83. Furthermore, because the cross section of the rail 83 is circular, the opening/closing plate 81 can rotate around the rail 83. In the yarn winding machine 1 of this embodiment, the operator manually operates the opening/closing guide 80. Alternatively, an actuator may be provided to drive the opening/closing guide 80.

The opening and closing plate 81 is also provided with a thread removal guide 84 and a thread separation guide 85. This allows the thread removal guide 84 and thread separation guide 85 to be moved closer to or further away from the thread path.

The thread removal guide 84 is provided at the short end of the opening/closing plate 81. In this embodiment, the opening/closing plate 81 and the thread removal guide 84 are integrally configured, but as described below, they may also be separate. The thread removal guide 84 is movable between a thread removal position (indicated by the dashed line in the upper diagram of Figure 7) in which the opening/closing plate 81 is rotated toward the regulating guide 60a, and a retracted position (in which the thread removal guide 84 is retracted from the thread removal position) in which the opening/closing plate 81 is rotated in the opposite direction. When in the thread removal position, the thread removal guide 84 interferes with the thread path when the traverse guide 23 holds the thread 91, allowing the thread 91 to be removed from the traverse guide 23. Furthermore, when in the thread removal position, the thread removal guide 84 can hold the thread 91 after it has been removed from the traverse guide 23, preventing it from returning to the traverse guide 23.

The split thread guide 85 is located at the short end of the opening/closing plate 81. The split thread guide 85 is configured with multiple plate-like members arranged side by side. The thread 91 is held by positioning it between the two plate-like members. The split thread guide 85 is a member that assists in holding the thread 91 in the traverse guide 23. Therefore, the interval at which the split thread guide 85 holds the thread 91 is the same as the interval at which the traverse guides 23 are arranged. Furthermore, the position at which the split thread guide 85 holds the thread 91 is within the traverse area of the corresponding traverse guide 23.

The split thread guide 85 is movable between a split thread position (dashed line in the upper diagram of Figure 7) in which the opening/closing plate 81 is rotated toward the regulating guide 60a, and a retracted position in which the opening/closing plate 81 is rotated in the opposite direction (retracting the split thread guide 85 from the split thread position). In the split thread position, the split thread guide 85 holds multiple threads 91 individually and separately by placing the threads 91 between plate-like members. Note that the configuration of the split thread guide 85 is just one example, and it may also be configured, for example, by forming grooves at regular intervals in a single plate.

The grip portion 86 is formed at one longitudinal end (the end on the front side) of the opening/closing plate 81. The grip portion 86 is the part that the operator holds with their hand when rotating the opening/closing plate 81.

Next, with reference to Figures 8 to 10, we will explain the process of threading using the restricting guide 60a, moving mechanism 70a, and opening/closing guide 80, followed by the start of package production.

First, the operator operates the operation panel 32 to rotate the bobbin holder 42 and drive the traverse device 21. At this time, the traverse guide 23 of the traverse device 21 is driven back and forth at a speed slower than the normal speed used during package production. As shown in Figure 8, the operator rotates the opening/closing guide 80 toward the restricting guide 60a, and then slides the opening/closing guide 80 toward the free end of the bobbin holder 42. The operator holds multiple yarns 91 hanging on the yarn feed roller 100 with a suction gun or the like. In this embodiment, the yarn 91 is supplied from the yarn feed roller 100 to the upper and lower winding sections 10. Therefore, the operator first threads all of the yarn 91 from the yarn feed roller 100 onto the upper winding section 10, then removes only the yarn 91 supplied to the lower winding section 10 and re-holds it with a suction gun or similar device. The held yarn 91 is then threaded onto the lower winding section 10. However, for simplicity's sake, the explanation will be given assuming that the yarn 91 supplied from the yarn feed roller 100 is threaded separately onto the upper and lower winding sections 10. Therefore, the operator holds the multiple yarns 91 supplied to the upper winding section 10 that are threaded on the yarn feed roller 100 with a suction gun or similar device. Next, the operator threads the threaded yarns 91 onto the yarn split guide 85. At this point, the operator does not need to thread the multiple yarns 91 separately onto the yarn split guide 85. At this point, the restriction guide 60a is in the retracted position.

Next, as shown in FIG. 9 , the operator slides the opening/closing guide 80 back to its original position. At this time, the restricting guide 60a is in the retracted position, so the thread 91 does not interfere with the restricting guide 60a. The operator winds the thread 91, which is hanging on the yarn split guide 85, around the bobbin 90 in one of the bobbin holders 42. This causes the thread 91 to be wound onto the bobbin 90. Next, the operator sets the restricting guide 60a to the restricting position, and then slightly rotates the opening/closing plate 81 up and down. By rotating the opening/closing plate 81 upward, for example, the thread release guide 84 causes the thread 91 to be released from the yarn split guide 85 and spread in the axial direction. At this time, because the restricting guide 60a is in the restricting position, the thread 91 is restricted so that it is positioned inside the restricting position of the restricting guide 60a, i.e., inside the axial region of the multiple bobbins 90 held in the bobbin holder 42 (the region where the multiple bobbins 90 are arranged in the axial direction). At the same time, the restricting guide 60a is slid in the axial direction. This distributes the restricting positions of the restricting guide 60a axially, distributing the multiple yarns 91 wound on the bobbins 90 at both ends of the bobbin holder 42 axially. This prevents localized thickening and reduces the resulting yarn breakage. The opening/closing plate 81 is then rotated downward, so that the yarns 91 are held by other yarn split guides 85. By repeating this process, the positions of the multiple yarns 91 can be spread (distributed) in the axial direction. Finally, the operator individually holds the multiple yarns 91 in the yarn split guides 85, so that each yarn 91 is positioned one by one in the axial region of each bobbin 90. Because the restricting guide 60a is in the restricting position, the yarns 91 do not move outside the axial region of the bobbin 90, preventing the axially spread yarns 91 from dropping off the bobbins 90.

Once the above steps are completed, the thread is threaded onto one of the bobbin holders 42 of the lower winding unit 10 in the same manner as for the upper winding unit 10.

Once the above-described operations have been completed in both the upper and lower winding sections 10, the operator operates the operation panel 32 in each of the upper and lower winding sections 10 to rotate the turret plate 40 and begin switching the position of the bobbin holder 42. At the same time, the traverse guide 23 of the traverse device 21 switches to normal high-speed operation. Almost simultaneously, as shown in FIG. 10 , the operator rotates the opening/closing guide 80 in each of the upper and lower winding sections 10 to return it to its original position. In other words, the yarn removal guide 84 and the yarn split guide 85 return to their retracted positions. Because each yarn 91 is positioned individually in the axial region of each bobbin 90, when the yarn removal guide 84 and the yarn split guide 85 are retracted, the multiple traverse guides 23 each hold a yarn 91. Once the yarn 91 is held by the traverse guide 23, the yarn 91 no longer needs to be regulated by the regulating guide 60a. The operator moves the regulating guide 60a to the retracted position. In this embodiment, the trajectory of the regulating guide 60a as it moves from the regulating position to the retracted position does not interfere with the yarn dividing guide 85, which is in the yarn dividing position. Therefore, the regulating guide 60a can be moved to the retracted position without interfering with the yarn dividing guide 85. Then, by rotating the turret plate 40 to switch the position of the bobbin holder 42, the bobbin 90 of the other bobbin holder 42 comes into contact with the contact roller 31, and the yarn 91 is wound onto the bobbin 90 to produce a package 92. The yarn 91 wound onto the bobbin 90 of one of the bobbin holders 42 for the above-mentioned threading operation is removed from the bobbin holder 42 along with the bobbin 90. A new bobbin 90 is then attached to the other bobbin holder 42.

In this embodiment, the upper and lower opening/closing guides 80 have the same configuration. Alternatively, the upper and lower opening/closing guides 80 may have different configurations. For example, the upper opening/closing guide 80 may have the configuration shown in FIG. 11. As shown in FIG. 1, the yarn path from the yarn feed roller 100 to the lower winding section 10 is parallel or approximately parallel to the vertical direction, whereas the yarn path from the yarn feed roller 100 to the upper winding section 10 is inclined relatively sharply relative to the vertical direction. Therefore, even if the opening/closing plate 81 is rotated up and down after the yarn 91 is hooked onto the split yarn guide 85, the split yarn guide 85 does not retract much relative to the yarn 91, so the yarn 91 may not be released from the split yarn guide 85 and may not spread in the axial direction.

In this regard, the opening and closing guide 80 shown in Figure 11 can operate the thread removal guide 84 and the yarn separation guide 85 separately. Specifically, the opening and closing guide 80 comprises a first opening and closing plate 81a and a second opening and closing plate 81b. The first opening and closing plate 81a and the second opening and closing plate 81b are rotatably attached to rails 83 separately. Note that the sliding function of the first opening and closing plate 81a and the second opening and closing plate 81b may be omitted. The thread removal guide 84 is attached to the first opening and closing plate 81a. The yarn separation guide 85 is attached to the second opening and closing plate 81b.

As shown in the upper diagram of Figure 11, when the thread removal guide 84 is in the thread removal position and the split thread guide 85 is in the split thread position, the thread removal guide 84 comes into contact with the thread 91, but the split thread guide 85 does not come into contact with the thread 91. Therefore, by rotating the first opening/closing plate 81a up and down in this state, the thread 91 can be spread in the axial direction. As shown in the upper diagram of Figure 11, even when the thread removal guide 84 is in the thread removal position, the restriction guide 60a, which is in the restriction position, interferes with the thread path and can restrict the thread 91.

During threading, the first opening/closing plate 81a rotates toward the first housing 20, and the thread removal guide 84 is in the retracted position. As shown in the lower diagram of Figure 11, even when the thread removal guide 84 is in the retracted position, the restriction guide 60a, which is in the restriction position, overlaps with the thread path. Therefore, the restriction guide 60a can restrict the thread 91 even during threading.

Next, the restriction guide 60b and movement mechanism 70b of the second embodiment will be described with reference to Figures 12 and 13. Note that in the following description, components that are the same as or similar to those in the previous embodiment will be given the same reference numerals in the drawings, and their description may be omitted. Furthermore, matters described in the previous embodiment also apply to the second embodiment unless a contradiction arises.

The second embodiment differs from the first embodiment mainly in the following two points. First, the restriction guide 60b is moved from the restriction position to the retracted position simply by sliding it without rotating it. Second, the operator slides the restriction guide 60b by operating the operating unit 75.

The following describes the restricting guide 60b and moving mechanism 70b of the second embodiment. The restricting guide 60b is disposed at each end of the second housing 30 in the axial direction. The two restricting guides 60b are symmetrical across a plane perpendicular to the axial direction, so the following describes both restricting guides 60b together.

The restricting guide 60b comprises an attachment portion 61, an intermediate portion 62, and an acting portion 63. The attachment portion 61 has substantially the same configuration as in the first embodiment. The intermediate portion 62 is a portion provided between the attachment portion 61 and the acting portion 63. The intermediate portion 62 is shaped to fit along the surface of the second housing 30. The acting portion 63 is provided in an upright position from the surface of the second housing 30. As a result, the acting portion 63 extends toward the first housing 20, allowing the acting portion 63 to interfere with the yarn path.

The movement mechanism 70b of the second embodiment includes two operating rods 73, multiple slide guides 74, and two operating units 75. The operating rods 73 are cylindrical members arranged along the axial direction. The two operating rods 73 are fixed to the two mounting units 61 so as not to move relative to each other. In other words, the operating rods 73 can move integrally with the restriction guides 60b.

Multiple slide guides 74 are provided along the axial direction. Each slide guide 74 has a through hole. An operating rod 73 is inserted into the through hole of the slide guide 74. This allows the restriction guide 60b and operating rod 73 to slide along the axial direction.

The operating unit 75 is provided at the end of the slide guide 74. The operating unit 75 has a larger diameter than the slide guide 74 so that it can be easily gripped by the operator. The operator can slide the restriction guide 60b along the axial direction by moving the operating unit 75 along the axial direction. To make it easier for the operator to operate, the two operating units 75 are provided at the end on the same side in the axial direction. The end on which the operating units 75 are provided is the end on the front side of the yarn winding machine 1, in other words, the end on the side where the operation panel 32 is provided.

When the operating part 75 is located at the position indicated by the solid line in Figure 12, the two regulating guides 60b are in the retracted position. At this time, the axial positions of the two operating parts 75 are the same. To move the two regulating guides 60b from this state to the regulating position indicated by the dashed line, the two operating parts 75 must be moved in different axial directions. Also, in the second embodiment, in both the regulating position and the retracted position, the acting part 63 is located closer to the yarn path in the direction perpendicular to the axis than the mounting part 61.

The process of threading using the restricting guide 60b and moving mechanism 70b is almost the same as in the above embodiment, so only the following supplementary explanation will be provided and an explanation of the entire threading process will be omitted. In the second embodiment, when the operator slides the opening/closing guide 80 back to its original position, the thread 91 moves from the outside of the action portion 63 of the restricting guide 60b, over the action portion 63, and into the inside of the action portion 63. For this reason, the outside of the action portion 63 has a smoothly curved shape to make it easier to guide the thread 91 into the inside of the action portion 63.

Next, the restriction guide 60c and movement mechanism 70c of the third embodiment will be described with reference to Figures 14 and 15. Furthermore, the matters described in the previous embodiments also apply to the third embodiment unless a contradiction arises.

In the third embodiment, the configuration for moving the restriction guide 60c from the restriction position to the retracted position differs from that of the first embodiment. The restriction guide 60c and the movement mechanism 70c are respectively disposed at both ends of the second housing 30 in the axial direction. The two sets of restriction guides 60c and movement mechanisms 70c are symmetrical across a plane perpendicular to the axial direction, and therefore the two sets of restriction guides 60c and movement mechanisms 70c will be described together below.

As shown in Figures 14 and 15, the movement mechanism 70c includes a slide rail 71 and a connecting member 76. The slide rail 71 is a cylindrical member arranged along the axial direction. The connecting member 76 is a member with a through hole formed therein. The slide rail 71 is inserted through the through hole of the connecting member 76 and serves as a support shaft member for the connecting member. This allows the connecting member 76 to slide along the slide rail 71. Furthermore, because the cross section of the slide rail 71 is circular, the connecting member 76 can rotate around the slide rail 71 as its center of rotation.

The restriction guide 60c includes an attachment portion 61, an action portion 63, and a weight portion 65. The attachment portion 61 is rotatably attached to the connecting member 76. The rotation direction of the attachment portion 61 relative to the connecting member 76 is parallel to the rotation direction of the connecting member 76 relative to the slide rail 71. As in the above embodiment, the action portion 63 acts on the thread 91 to restrict it. The weight portion 65 is located on the opposite side of the attachment portion 61 from the action portion 63. The weight portion 65 prevents the action portion 63 from rotating downward.

With this configuration, the restricting guide 60c can be moved closer to or further away from the yarn path by rotating the connecting member 76 relative to the slide rail 71. Specifically, when the connecting member 76 extends from the slide rail 71 toward the yarn path in the direction perpendicular to the axis, the restricting guide 60c can be placed in a restricting position. On the other hand, when the connecting member 76 extends from the slide rail 71 to the opposite side of the yarn path in the direction perpendicular to the axis, the restricting guide 60c can be placed in a retracted position.

When the restriction guide 60c is in the restriction position, the weight portion 65 is supported by the movement mechanism 70c, keeping the action portion 63 approximately horizontal. On the other hand, when the restriction guide 60c is in the retracted position, the weight portion 65 is supported by the second housing 30, allowing the action portion 63 to be oriented upward. This makes it possible not only to move the restriction guide 60c forward and backward in the direction perpendicular to the axis, but also to retract it from the yarn path depending on the orientation of the action portion 63.

In addition, in the third embodiment, in both the restricting position and the retracted position, the acting portion 63 is located closer to the yarn path in the direction perpendicular to the axis than the mounting portion 61. The process of threading using the restricting guide 60c and the moving mechanism 70c is the same as in the above embodiment, so a description thereof will be omitted.

As described above, the yarn winding machine 1 winds multiple yarns 91 delivered from the yarn feed roller 100 onto multiple bobbins 90 to produce packages 92. The yarn winding machine 1 of this embodiment includes a bobbin holder 42, multiple traverse guides 23, a yarn removal guide 84, restriction guides 60a, 60b, and 60c, and movement mechanisms 70a, 70b, and 70c. The bobbin holder 42 holds multiple bobbins 90. The traverse guides 23 contact the multiple yarns 91 and traverse the yarns 91 in the axial direction of the bobbin holder. The yarn removal guide 84 holds the multiple yarns 91 after they have been released from the multiple traverse guides 23. The restriction guides 60a, 60b, and 60c restrict the plurality of threads 91 held by the thread removal guide 84 so that the position of the thread 91 in the axial direction of the bobbin holder is inside the axial region of the plurality of bobbins 90 held in the bobbin holder 42. The movement mechanisms 70a, 70b, and 70c enable the restriction guides 60a, 60b, and 60c to move between a restriction position where they act on the thread 91 to restrict the thread 91 and a retracted position where they are retracted from the restriction position. The thread removal guide 84 is movable between a holding position where it holds the plurality of threads 91 and a retracted position where it is retracted from the holding position. The portions of the regulating guides 60a, 60b, 60c that are attached to the moving mechanisms 70a, 70b, 70c are referred to as attachment portions 61, and the portions that act on the yarn 91 are referred to as action portions 63. When the direction in which the yarn feed roller 100 is positioned relative to the yarn winding machine 1 is referred to as the height direction and the direction perpendicular to both the height direction and the bobbin holder axial direction is referred to as the axially perpendicular direction, the action portions 63 are located closer to the yarn path in the axially perpendicular direction than the attachment portions 61 in both the regulating position and the retracted position.

As a result, the restricting guides 60a, 60b, and 60c restrict the yarn 91 to within the axial region of the bobbin 90, preventing the yarn 91 from spreading when the yarn 91 is removed from the traverse guide 23. This facilitates the threading operation of hooking the yarn 91 onto the bobbin holder 42. Furthermore, when the restriction of the yarn 91 is no longer required, the restricting guides 60a, 60b, and 60c can be moved to the retracted position, making handling easier than with a configuration that requires attachment and detachment. Furthermore, the restricting guides 60a, 60b, and 60c can be moved between the restricting position and the retracted position without significantly changing their orientation. This reduces the movement trajectory of the restricting guides 60a, 60b, and 60c, thereby allowing for more space for arranging other components. Furthermore, preventing the yarn 91 from spreading when the yarn 91 is removed from the traverse device 21 reduces the likelihood of yarn dropout. As a result, yarn breakage due to yarn dropout can be reduced.

In the yarn winding machine 1 of this embodiment, the movement mechanisms 70a, 70b, and 70c have mechanisms for sliding the restriction guides 60a, 60b, and 60c in the axial direction of the bobbin holder at least inside the axial region of multiple bobbins 90.

During threading, the winding positions of the yarn 91 restricted by the restriction guides 60a, 60b, and 60c can be dispersed by sliding the restriction guides 60a, 60b, and 60c in the restricting position.

In the yarn winding machine 1 of this embodiment, the restricting guides 60a, 60b slide in the axial direction of the bobbin holder, switching between the restricting position and the retracted position of the restricting guides 60a, 60b.

This allows for easy switching between the restricted position and the retracted position with a small movement trajectory.

The yarn winding machine 1 of this embodiment is equipped with an operating unit 75 that is arranged on the axial end side of the bobbin holder relative to the restricting guide 60b, is connected to the restricting guide 60b, and can be operated to slide the restricting guide 60b.

This makes it easier to slide the restriction guide 60b compared to operating it by directly touching it.

In the yarn winding machine 1 of this embodiment, the restriction guide 60a switches from the restriction position to the retracted position when the action portion 63 moves in the height direction away from the yarn feed roller 100.

This makes it less likely to interfere with the operation of other devices.

In the yarn winding machine 1 of this embodiment, the movement mechanism 70a is provided with a support rail 72 that is arranged along the bobbin holder axial direction and supports the restriction guide 60a so that the restriction guide 60a maintains its restriction position. The restriction guide 60a is slidable in the bobbin holder axial direction along the support rail 72. The restriction guide 60a switches from the restriction position to the retracted position by sliding past the point where the support rail 72 is located.

This allows the same component to be used to assist sliding and to maintain the restriction guide 60a in the restriction position. It also makes it easy to switch from the restriction position to the retracted position.

In the yarn winding machine 1 of this embodiment, the movement mechanism 70c includes a slide rail 71 and a connecting member 76 that connects the slide rail 71 to the restriction guide 60c. In the restriction position, the connecting member 76 extends from the slide rail 71 toward the yarn path in the direction perpendicular to the axis. In the retracted position, the connecting member 76 extends from the slide rail 71 to the side opposite the yarn path in the direction perpendicular to the axis.

This allows the movement trajectory of the restriction guide 60c to be smaller than in a configuration in which the restriction guide 60c itself is inverted.

The yarn winding machine 1 of this embodiment comprises a first housing 20 and a second housing 30. A traverse device 21 is disposed in the first housing 20. The second housing 30 is disposed opposite the first housing 20 across the yarn path. The yarn removal guide is disposed in the first housing. Restriction guides 60a, 60b, and 60c are disposed in the second housing 30.

This allows the thread removal guide 84 and the restriction guides 60a, 60b, and 60c to be optimally positioned.

The yarn winding machine 1 of this embodiment is equipped with a yarn splitting guide 85 that separates the yarns 91 and holds them in the traverse regions of the multiple traverse guides 23. The yarn splitting guide 85 is movable between a yarn splitting position where it separates and holds the multiple yarns 91, and a retracted position where it is retracted from the yarn splitting position.

This allows the multiple threads 91 to be regulated by the regulation guides 60a, 60b, and 60c while each of the multiple threads 91 is guided to the traverse area of each traverse guide 23 and brought into contact with (engage with) each traverse guide 23, making threading easier.

In the yarn winding machine 1 of this embodiment, the pitch between multiple yarns on the bobbin holder 42 is smaller than the pitch between multiple yarns on the yarn feed roller 100.

If the pitch between the multiple threads on the bobbin holder 42 is smaller than the pitch between the multiple threads on the yarn feed roller 100, the multiple threads 91 tend to spread out over a wider area than the axial area of the multiple bobbins 90 held in the bobbin holder 42, so the effect of providing the restriction guides 60a, 60b, and 60c can be effectively utilized.

The above describes a preferred embodiment of the present invention, but the above configuration can be modified, for example, as follows:

In the yarn winding machine 1 of the above embodiment, the winding units 10 are arranged vertically. Alternatively, the winding units 10 may be arranged horizontally, or the yarn winding machine 1 may be provided with only one winding unit 10.

In the above embodiment, the traverse device 21 is a cam drum type, but a different configuration may be used as long as the traverse guide 23 can be moved back and forth in the winding width direction. For example, a belt-type traverse device may be used instead of the traverse device 21.
