Description

Silk thread winding machine

Technical Field

The present invention relates generally to a yarn winding machine for winding a plurality of yarns fed from a yarn feeding roller around a plurality of bobbins, respectively, to manufacture a package.

Background

Patent document 1 is japanese patent laid-open publication No. 2003-226469.

The yarn winding machine of patent document 1 includes a traverse device, and 1 st and 2 nd bobbin holders. The traverse device traverses each of the plurality of filaments fed from the godet (feed roller). The 1 st and 2 nd bobbin holders are respectively provided with a plurality of bobbins. The yarn winding machine winds the yarn around each of the plurality of bobbins of the 1 st bobbin holder to manufacture a package, and when the manufacture of the package is completed (the package becomes a full package), switches the yarn winding target to the plurality of bobbins of the 2 nd bobbin holder.

The godet disclosed in patent document 1 has a length in the axial direction shorter than that of the bobbin holder. Thus, as the plurality of wires from the godet roll toward the bobbin holder go downstream, the interval between the wires becomes wider. Therefore, when the plurality of wires are removed from the traverse device when switching the bobbins, the interval between the wires becomes narrow and gets closer to the center. To solve this problem, the yarn winding machine of patent document 1 includes a yarn passage changing member. The yarn channel changing member restricts the movement of each yarn so that the distance between the yarns is not narrowed when the plurality of yarns are removed from the traverse device.

The yarn winding machine of patent document 1 suppresses narrowing of the interval between the yarns in the case of removing a plurality of yarns from the traversing device. On the other hand, depending on the device conditions or winding conditions, there is a possibility that the interval between the wires becomes wider when the state of the plurality of wires is removed from the traverse device. For example, when the axial length of the yarn feeding roller is longer than the bobbin holder, the yarn may be wound around a plurality of bobbins of the bobbin holder. As a result, since the plurality of threads are scattered in a wider range than the plurality of bobbin mounting regions of the bobbin holder, it is difficult to perform a work of winding the plurality of threads around the plurality of bobbins of the bobbin holder. Further, since the plurality of wires are unraveled, the wires may fall to the outside in the axial direction of the bobbin at the time of winding, and as a result, breakage may occur.

Disclosure of Invention

The present invention has been made in view of the above circumstances, and a main object thereof is to provide a yarn winding machine capable of easily performing a yarn winding operation on a bobbin holder and capable of suppressing yarn breakage due to yarn breakage by suppressing a plurality of yarns from being scattered in a range wider than an axial region of a plurality of bobbins held by the bobbin holder when the yarns are removed from a traverse device.

The means for solving the problems and the effects thereof will be described as described above.

According to an aspect of the present invention, a wire winder configured as follows is provided. That is, the yarn winding machine winds a plurality of yarns fed from the yarn feeding roller around a plurality of bobbins, respectively, to manufacture a package. The yarn winding machine is provided with a bobbin bracket, a plurality of traverse yarn guides, a yarn removing yarn guide, a limiting yarn guide and a moving mechanism. The bobbin holder holds the plurality of bobbins. The traverse guide is brought into contact with each of the plurality of wires to traverse the wires along the axial direction of the bobbin holder. The thread removing guide holds the thread in a state in which the plurality of threads are removed from the plurality of traverse guides. The limiting guides are disposed so as to correspond to both side portions of the axial regions of the plurality of bobbins, respectively, and limit the plurality of threads held by the thread removing guides so that the position of the thread in the axial direction of the bobbin holder is located inside the axial regions of the plurality of bobbins held by the bobbin holder. The movement mechanism can move the restricting guide between a restricting position for restricting the wire by acting on the wire and a retracted position retracted from the restricting position. The thread removing guide is movable between a holding position where a plurality of threads are held and a retracted position retracted from the holding position. When the portion of the restriction yarn guide attached to the moving mechanism is an attachment portion, a portion acting on the yarn is an action portion, a height direction is a direction in which the yarn feeding roller of the yarn winding machine is located, and an axis orthogonal direction is a direction orthogonal to both the height direction and the bobbin holder axial direction, the action portion is located closer to the yarn path side than the attachment portion in the axis orthogonal direction in both the restriction position and the retracted position.

Thus, the restriction yarn guide restricts the yarn to the inside of the region in the axial direction of the plurality of bobbins, and therefore, the yarn can be suppressed from being unraveled when the yarn is removed from the traverse device. Therefore, the yarn winding operation of winding the yarn on the bobbin holder can be easily performed. In addition, when the wire is not required to be restricted, the restricting wire guide is moved to the retracted position, and therefore, the processing is easier than the structure requiring attachment and detachment. Further, the limit wire guide can be moved between the limit position and the retracted position without largely changing the posture of the limit wire guide. Therefore, since the movement locus of the wire guide is limited to be small, the arrangement space of other components can be enlarged. Further, the yarn can be suppressed from being unraveled in the case of removing the yarn from the traverse device, and thus yarn drop is difficult to occur. As a result, the occurrence of yarn breakage due to yarn breakage can be suppressed.

In the above-described yarn winding machine, the moving mechanism preferably includes a mechanism for axially sliding the restricting yarn guide along the bobbin holder at least inside the axial region of the plurality of bobbins.

In the yarn winding operation, the winding position of the yarn limited by the limiting guide can be dispersed by sliding the limiting guide at the limiting position.

In the above-described yarn winding machine, it is preferable that the restricting guide slides in the axial direction along the bobbin holder, and the restricting position and the retracted position of the restricting guide be switched.

This allows the restricting position and the retracted position to be switched by a simple operation with a small movement locus.

The yarn winding machine preferably includes an operation unit that is disposed on an end side of the bobbin holder in an axial direction with respect to the limiting yarn guide and is coupled to the limiting yarn guide, and is capable of performing an operation of sliding the limiting yarn guide.

Thus, the restriction guide can be easily slid as compared with the case where the restriction guide is operated in direct contact therewith.

In the above-described yarn winding machine, it is preferable that the limiting yarn guide is switched from the limiting position to the retracted position by moving the operating portion in the height direction in a direction in which the operating portion is away from the yarn feeding roller.

This makes it difficult to prevent other devices from operating.

In the above-described yarn winding machine, the following configuration is preferable. That is, the moving mechanism includes a support rail that is provided along the axial direction of the bobbin holder and supports the restricting guide so that the restricting guide maintains the restricting position. The limiting thread guide can slide along the supporting track along the axial direction of the bobbin bracket. The restricting guide slides over a portion where the support rail is disposed, and is switched from the restricting position to the retracted position.

Thus, the member for assisting the sliding and the member for maintaining the restriction guide at the restriction position can be shared. Further, the switching from the restricting position to the retracted position can be performed easily.

In the above-described yarn winding machine, the following configuration is preferable. That is, the moving mechanism includes a support shaft member and a connecting member that connects the support shaft member and the restriction guide. In the limiting position, the connecting member extends from the support shaft member toward the wire passage side in the axial direction perpendicular to the shaft. In the retracted position, the coupling member extends from the support shaft member to the opposite side of the wire passage in the axial direction.

Thus, the movement locus of the restriction guide can be reduced as compared with a configuration in which the restriction guide itself is reversed.

In the above-described yarn winding machine, the following configuration is preferable. That is, the wire winder includes a 1 st housing and a 2 nd housing. The traverse guide is disposed in the 1 st housing. The 2 nd casing is disposed opposite to the 1 st casing with a yarn passage interposed therebetween. The thread removing guide is disposed in the 1 st housing. The restriction guide is disposed in the 2 nd housing.

Thereby, the wire removal guide and the restriction guide can be appropriately configured.

In the above-described yarn winding machine, the following configuration is preferable. That is, the yarn feeder is provided with a yarn dividing guide that separates and holds a plurality of yarns individually in each of the traverse regions of the plurality of traverse guides. The yarn dividing guide is movable between a yarn dividing position for dividing and holding a plurality of yarns and a retracted position for retracting from the yarn dividing position.

Thus, the plurality of wires can be guided to the traverse regions of the traverse guides while being restrained by the restraining guides, and brought into contact (engagement) with the traverse guides, thereby facilitating the wire winding operation.

In the yarn winding machine, it is preferable that a pitch between the plurality of yarns on the bobbin holder is smaller than a pitch between the plurality of yarns on the yarn feeding roller.

When the pitch between the plurality of wires on the bobbin holder is smaller than the pitch between the plurality of wires on the yarn feeding roller, the plurality of wires tend to spread out over a wider range than the axial region of the plurality of bobbins held by the bobbin holder, and therefore the effect of providing the above-described yarn guide limiter can be effectively exhibited.

Detailed Description

Next, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a front view of a wire winder 1 according to embodiment 1. Fig. 2 is a block diagram of the wire winder 1. In the following description, the upstream or downstream of the running direction of the yarn may be simply referred to as upstream or downstream.

A spinning machine, not shown, is disposed upstream of the yarn winding machine 1 shown in fig. 1. The yarn 91 produced by the spinning machine is fed to the yarn winding machine 1 via the yarn feeding roller 100. The yarn winding machine 1 winds the yarn 91 around the bobbin 90 to form a yarn layer on the bobbin 90, thereby manufacturing the package 92. The yarn 91 is an elastic yarn such as Spandex (Spandex). However, the type of the yarn 91 is not limited to this, and may be, for example, a synthetic fiber yarn such as nylon or polyester.

As shown in fig. 1, the wire winding machine 1 includes two winding units 10 arranged vertically. The yarn 91 is supplied to each winding portion 10 independently, and the package 92 is manufactured independently by each winding portion 10. A plurality of wires 91 aligned in the axial direction of the package 92 are supplied to the winding portion 10. The winding unit 10 winds a plurality of wires 91, respectively, to manufacture a plurality of packages 92.

Since the two winding units 10 are each provided with the same device, the upper and lower winding units 10 will be described together. As shown in fig. 1, the winding unit 10 includes a frame 11, a 1 st case 20, a 2 nd case 30, and a turntable 40.

The frame 11 is a member for holding each part of the winding part 10. The 1 st housing 20 is provided with a traverse device 21. The traverse device 21 traverses the yarn 91 conveyed downstream by reciprocating in the winding width direction (the axial direction of the package 92) while the traverse guide 23 engages with the yarn 91, which will be described later. As shown in fig. 2, the traverse device 21 includes a traverse cam 22, a traverse guide 23, and a traverse motor 24. Fig. 2 is a block diagram of one winding unit 10.

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

The traverse guide 23 is a portion engaged with the wire 91. The tip of the traverse guide 23 has, for example, a substantially U-shaped guide portion, and engages with the thread 91 so as to sandwich the thread 91 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 rotationally driving the traverse cam 22, the traverse guide 23 can be reciprocally moved in the winding width direction.

The traverse motor 24 is controlled by the control device 50. The control device 50 includes CPU, ROM, RAM and the like. The CPU reads out and executes the program stored in the ROM to the RAM, thereby executing various controls related to the winding section 10.

The 2 nd housing 30 is rotatably provided with a contact roller 31. When winding the yarn 91, the contact roller 31 is driven to rotate while being in contact with the yarn layer of the package 92 at a predetermined pressure, thereby adjusting the yarn layer shape of the package 92.

An operation panel 32 is provided on the 2 nd casing 30. The operation panel 32 is a device operated by an operator. The operator instructs the winding unit 10 by operating the operation panel 32. The instruction of the operator is, for example, start of winding, stop of winding, change of winding conditions, or the like.

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

Bobbin holders 42 are provided at two positions of the turntable plate 40 facing each other with a center therebetween. A plurality of bobbins 90 can be mounted on the bobbin holder 42 in an axially aligned manner. By rotating the turret plate 40, the positions of the two bobbin holders 42 can be changed. Each bobbin holder 42 is supported by the turntable plate 40 in a cantilever state.

The bobbin holder 42 is rotatable with respect to the turntable plate 40 about the axial position of the bobbin holder 42. The two bobbin holders 42 are respectively and independently rotatably driven by bobbin holder motors 43 shown in fig. 2. The bobbin holder motor 43 is controlled by a control device 50.

The yarn 91 is wound on the higher bobbin holder 42 in a state where the two bobbin holders 42 are arranged vertically. Specifically, after the yarn winding is performed on the yarn bobbin 90 of one yarn bobbin holder 42, the yarn 91 is wound on the yarn bobbin 90 of the other yarn bobbin holder 42 by rotating the other yarn bobbin holder 42 in this state while the other yarn bobbin holder 42 is in contact with the contact roller 31, and the package 92 is manufactured. A tip support member 45 (fig. 1) is provided to the bobbin holder 42 located at a position contacting the contact roller 31, and the tip support member 45 is configured to support the free end side end of the bobbin holder 42.

When the predetermined amount of the yarn 91 is wound and the package 92 reaches full winding, the positions of the two bobbin holders 42 are switched by rotating the platen 40. Thereafter, the package 92 having been fully wound is recovered, and the yarn 91 is wound around the bobbin 90 attached to the one bobbin holder 42.

Next, in the former stage of the production of the package 92, the operator performs a yarn winding operation for winding the yarn 91 around the bobbin 90 of one bobbin holder 42 of the two bobbin holders 42, and then performs a surplus winding operation, and this yarn winding operation and the surplus winding operation will be described. In the present 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 are collectively referred to as "axial direction". Further, the direction in which the feed roller 100 of the wire winder 1 is located will be referred to as "height direction". In particular, the side closer to the godet 100 in the height direction is referred to as the upper side, and the opposite side is referred to as the lower side. The direction orthogonal to both the axial direction and the height direction is referred to as "axial direction orthogonal direction".

In the stage of winding up the yarn by the operator, the yarn 91 is wound up in a state where the yarn 91 is not engaged with the traverse guide 23. Further, the traverse guide 23 is driven at a lower speed than usual. Therefore, even if the yarn 91 engages with the traverse guide 23 after the yarn is wound, the quality of the yarn 91 cannot be ensured until the traverse guide 23 reaches the normal speed. Therefore, it is necessary to wind the low-quality wire 91 by performing the surplus winding, and discard the wound wire 91.

In the present embodiment, the length of the bobbin holder 42 in the axial direction (the length indicated by the symbol L2 in fig. 3) is smaller than the length of the godet 100 in the axial direction (the length indicated by the symbol L1 in fig. 3). Accordingly, the spacing between filaments on the spool support 42 is smaller than the spacing between filaments on the feed roll 100. When the surplus winding is performed under such conditions, the following may occur. That is, when the yarn 91 is wound around the bobbin 90 from the yarn feeding roller 100, yarn 91 located at the axial end of the yarn feeding roller 100 falls on the outer side in the axial direction of the bobbin 90 disposed at the axial end, and as a result, yarn breakage may occur. Further, even if no yarn drop occurs, as shown in fig. 4, the plurality of yarns 91 may be concentrated at the axial end of the bobbin 90. As a result, the thickness of the yarn layer is locally increased when the winding is performed at the axial end portion, and therefore, the yarn layer may collapse to cause yarn breakage.

In order to suppress breakage due to yarn drop and partial winding, the yarn winding machine 1 of the present embodiment includes a limiting yarn guide 60a and a moving mechanism 70a. The range in which the wire guide 60a restricts the position of the wire 91 is referred to as a restriction range (a length indicated by a symbol L3 in fig. 3). The limiting range is located inside the axial region of the plurality of bobbins 90 (the region where the plurality of bobbins 90 are attached to the bobbin holder 42). The restriction guide 60a and the moving mechanism 70a of the present embodiment are disposed on the upper surface of the 2 nd housing 30. However, the limiting guide 60a and the moving mechanism 70a may be disposed at other positions where the wire 91 can be limited.

The following describes the structure of the limit wire guide 60a and the movement mechanism 70a with reference to fig. 3 and 5.

The limit wire guides 60a are provided so as to correspond to both side portions of the region in the axial direction of the plurality of bobbins 90 (in other words, to both side portions in the axial direction of the bobbin holder 42), respectively. The two side portions refer to one side and the other side with respect to the center in the axial direction. More specifically, the limiting guides 60a are provided so as to correspond to both end portions of the axial regions of the plurality of bobbins 90, respectively. In this specification, an end portion is a term indicating a range including not only an end point but also the vicinity thereof. One restriction guide 60a restricts 1 or more wires 91 on one side in the axial direction, and the other restriction guide 60a restricts 1 or more wires 91 on the other side in the axial direction. Since the two restriction guides 60a are symmetrical with respect to the plane perpendicular to the axial direction, the two restriction guides 60a will be described together.

The limiting guide 60a is a member that directly acts on the wire 91 (contacts the wire 91) to limit the wire 91. The limit wire guide 60a is a member manufactured by punching a plate material, bending, or the like. However, the restriction guide 60a may be manufactured by mounting a plurality of members.

As shown in fig. 3 and 5, the restriction guide 60a includes a mounting portion 61, an intermediate portion 62, and an operating portion 63. The mounting portion 61 is a portion mounted to the moving mechanism 70a. Specifically, the mounting portion 61 is a portion in which a through hole is formed. The intermediate portion 62 is a portion formed between the mounting portion 61 and the acting portion 63. The acting portion 63 is inclined with respect to the intermediate portion 62, and is a portion in contact with the wire 91.

The moving mechanisms 70a are provided on both side portions in the axial direction, respectively. Since the two moving mechanisms 70a have symmetrical shapes across a plane perpendicular to the axial direction, the two moving mechanisms 70a will be described together. As shown in fig. 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 columnar member provided along the axial direction. The slide rail 71 is inserted into the through hole of the mounting portion 61. Thereby, the wire guide 60a is restricted from being able to slide along the slide rail 71. Further, since the cross section of the slide rail 71 is circular, the wire guide 60a is restricted to be rotatable about the slide rail 71 as a rotation center. In the wire winding machine 1 of the present embodiment, the operator manually slides or rotates the limit wire guide 60 a. Alternatively, an actuator may be provided that drives the limit wire guide 60 a. In the present embodiment, the slide rail 71 functions as both a rail for sliding the restriction guide 60a and a rotation shaft (support shaft member) for supporting and rotating the restriction guide 60 a. Instead, a member functioning as a rail and a member functioning as a rotation shaft may be separately provided.

The support rail 72 is located closer to the 1 st housing 20 than the slide rail 71. The support rail 72 is provided in the axial direction, similarly to the slide rail 71. As shown in the upper view of fig. 5, the support rail 72 restricts downward rotation of the wire guide 60a (in other words, downward movement of the acting portion 63) by supporting the intermediate portion 62. Thereby, the restriction guide 60a can be maintained at the restriction position. The restricting position is a position where the restricting wire guide 60a restricts the wire 91. The restricting wire guide 60a is capable of changing the restricting position in the axial direction by sliding in the axial direction in a state where the support rail 72 supports the intermediate portion 62.

Further, the support rail 72 is not formed near the end in the axial direction. In other words, the range in which the slide rail 71 is formed and the support rail 72 is not formed exists on the moving mechanism 70 a. That is, since the intermediate portion 62 is not supported by the support rail 72 by sliding the wire guide 60a beyond the portion where the support rail 72 is disposed to the extent where the support rail 72 is not formed, the wire guide 60a is restricted from rotating downward (the acting portion 63 moves downward). Thereby, the movement of the wire guide 60a to the retracted position is restricted. The retracted position is a position retracted from the restriction position, and is a position where restriction of the wire 91 is not performed (the wire passage is not disturbed).

The restriction guide 60a of the present embodiment is retracted from the wire passage to the outside in the axial direction by sliding to the end in the axial direction, and is retracted from the wire passage by rotating downward. That is, the limiting guide 60a of the present embodiment is located on the wire passage side of the mounting portion 61 in the axial direction in both the limiting position and the retracted position, and the acting portion 63 is located on the axial direction orthogonal thereto.

With this configuration, the movement locus of the wire guide 60a can be reduced. Specifically, it is assumed that the movement locus of the restriction guide 60a is increased when the restriction guide 60a is rotated upward by 180 ° or more to retract (that is, when the attachment portion 61 is located on the wire passage side of the action portion 63). As a result, a large space needs to be left above the restriction guide 60 a.

In contrast, in the present embodiment, the space above the restriction guide 60a is not included in the movement locus of the restriction guide 60 a. Therefore, the space can be effectively utilized. As shown in fig. 6, in the present embodiment, the oil droplet tray 12 is disposed in this space. The drip tray 12 is a member for protecting the 1 st housing 20, the 2 nd housing 30, the wire passage therebetween, and the like from oil. Further, members other than the oil droplet tray 12 may be disposed in the space.

Even when an axial force is applied to the restriction guide 60a due to vibration or the like, the end surface of the support rail 72 of the intermediate portion 62 interferes with the other end surface, and therefore the restriction position is not returned. Thus, the support rail 72 has both a function of maintaining the limit wire guide 60a at the limit position and a function of maintaining the limit wire guide 60a at the retracted position. In the present embodiment, since the thread path can be retracted only by sliding in the axial direction, a mechanism for restricting the downward rotation of the thread guide 60a to retract is not required, and the mechanism can be omitted. The limiting guide 60a of the present embodiment is used for the surplus winding, but may be used in other situations where yarn drop may occur (for example, in a work of winding the yarn 91 around the bobbin 90).

Next, the opening and closing yarn guide 80 used in the surplus winding together with the limiting yarn guide 60a and the moving mechanism 70a will be described with reference to fig. 6 and 7.

The opening/closing wire guide 80 is disposed on the upper surface of the 1 st housing 20. In other words, when viewed from the axial direction, the opening/closing yarn guide 80 and the limiting yarn guide 60a are disposed so as to face each other with the yarn path therebetween. As shown in fig. 7, the opening/closing wire guide 80 includes an opening/closing plate 81, a tubular member 82, a rail 83, a wire removal wire guide 84, a wire separation wire guide 85, and a grip 86.

The opening/closing plate 81 is a flat plate having a slender shape, and is disposed in an orientation in which the longitudinal direction coincides with the axial direction. A tubular member 82 is immovably fixed to an end of the opening/closing plate 81 in the short side direction. The tubular member 82 has a through hole.

The rail 83 is a columnar member provided in the axial direction. The rail 83 is inserted through the through hole of the tubular member 82. Thereby, the cylindrical member 82 can slide along the rail 83. The tubular member 82 is fixed to the shutter 81, and therefore the shutter 81 can slide along the rail 83 in the axial direction. Further, since the rail 83 has a circular cross section, the shutter 81 can rotate around the rail 83 as a rotation center. In the yarn winding machine 1 of the present embodiment, the operator manually operates the opening/closing yarn guide 80. Instead, an actuator for driving the opening/closing wire guide 80 may be provided.

The opening/closing plate 81 is provided with a thread removing thread guide 84 and a thread dividing thread guide 85. Thereby, the wire removal guide 84 and the split guide 85 can be brought close to or separated from the wire channel.

The thread removing guide 84 is provided at an end portion of the opening and closing plate 81 in the short side direction. In the present embodiment, the opening/closing plate 81 is integrally formed with the thread removing guide 84, but may be formed separately as will be described later. The thread removing guide 84 is movable between a thread removing position (broken line of the upper drawing of fig. 7) in which the shutter plate 81 is rotated toward the restricting guide 60a side, and a retracted position (retracted position in which the thread removing guide 84 is retracted from the thread removing position) in which the shutter plate 81 is rotated toward the opposite side. The wire removal guide 84 in the wire removal position interferes with the wire path when the traverse guide 23 holds the wire 91, enabling the wire 91 to be removed from the traverse guide 23. Further, the wire removal guide 84 located at the wire removal position can hold the wire 91 removed from the traverse guide 23 so as not to return to the traverse guide 23 side.

The yarn dividing guide 85 is disposed at an end portion of the opening/closing plate 81 in the short side direction. The yarn dividing guide 85 is configured by arranging a plurality of plate-like members. The wire 91 is held by being positioned between two plate-like members. The thread-dividing guide 85 is a member for assisting the traverse guide 23 in holding the thread 91, and therefore, the thread-dividing guide 85 holds the thread 91 at the same interval as the traverse guide 23 is disposed. And, the wire dividing guide 85 keeps the position of the wire 91 within the traversing area of the corresponding traversing guide 23.

The yarn separating guide 85 is movable between a yarn separating position (broken line in the upper view of fig. 7) in which the opening/closing plate 81 is rotated toward the restricting guide 60a, and a retracted position in which the opening/closing plate 81 is rotated toward the opposite side (in which the yarn separating guide 85 is retracted from the yarn separating position). The yarn dividing guide 85 located at the yarn dividing position holds the plurality of yarns 91 in a state of being individually separated by interposing the yarns 91 between the plate-like members. The yarn dividing guide 85 is an example, and may be configured such that grooves are formed at regular intervals in one sheet of material.

The grip 86 is formed at one end (front end) of the opening/closing plate 81 in the longitudinal direction. The grip 86 is a portion to be gripped by the hand of the operator when rotating the shutter 81.

Next, a process from the thread winding operation using the limiting guide 60a, the moving mechanism 70a, the opening/closing guide 80, and the like to the start of package manufacturing will be described with reference to fig. 8 to 10.

First, the operator operates the operation panel 32 to rotate and drive the bobbin holder 42 and drive the traverse device 21. At this time, the traverse guide 23 of the traverse device 21 is reciprocally driven at a low speed lower than a normal speed at the time of package manufacture. As shown in fig. 8, the operator rotates the opening/closing wire guide 80 toward the limiting wire guide 60a, and then moves the opening/closing wire guide 80 laterally toward the free end of the spool holder 42. The operator holds the plurality of wires 91 wound around the godet 100 with a suction gun or the like. In the present embodiment, the yarn 91 is fed from the yarn feeding roller 100 to the upper winding section 10 and the lower winding section 10. Therefore, the operator first winds all the wires 91 from the godet 100 around the upper winding portion 10, then, takes out only the wires 91 supplied to the lower winding portion 10, holds the wires 91 again by a suction gun or the like, and winds the held wires 91 around the lower winding portion 10, but for simplicity of explanation, the description will be given by dividing the wires 91 supplied from the godet 100 into the upper winding portion 10 and the lower winding portion 10. Therefore, the operator holds the plurality of wires 91 wound on the upper side of the godet 100 and supplied to the winding unit 10 with a suction gun or the like. Next, the operator winds the held yarn 91 around the yarn dividing guide 85. At this time, the operator does not need to separately wind the plurality of wires 91 around the yarn dividing guide 85. At this time, the restriction guide 60a is located at the retracted position.

Next, as shown in fig. 9, the operator slides the opening/closing wire guide 80 to return to the original position. At this time, since the limit wire guide 60a is located at the retracted position, the wire 91 does not interfere with the limit wire guide 60a. The operator winds the yarn 91 wound around the yarn dividing guide 85 around the bobbin 90 of the one bobbin holder 42. Thereby, the yarn 91 is gradually wound around the bobbin 90. Next, the operator slightly rotates the opening/closing plate 81 up and down after positioning the restriction guide 60a at the restriction position. By rotating the opening and closing plate 81 to the upper side, for example, the wire 91 is removed from the wire dividing guide 85 by the wire removing guide 84 and is spread out in the axial direction. At this time, the wire guide 60a is positioned at the restricting position, so that the position of the wire 91 is positioned inside the restricting position of the wire guide 60a, that is, inside the region in the axial direction of the plurality of bobbins 90 held by the bobbin holder 42 (the region in which the plurality of bobbins 90 are arranged in the axial direction). At the same time, the restriction guide 60a is caused to move slidably in the axial direction. Accordingly, since the restricting positions of the restricting yarn guides 60a are dispersed in the axial direction, the plurality of yarns 91 wound around the bobbins 90 on both end portions of the bobbin holder 42 are dispersed in the axial direction, and thus, the partial winding thickness can be suppressed, and thus, the yarn breakage caused by this can be suppressed. Thereafter, the shutter 81 is rotated downward, whereby the yarn 91 is held by the other yarn dividing guides 85. By repeating this operation, the positions of the plurality of wires 91 can be dispersed (scattered) in the axial direction. Finally, the operator holds the plurality of threads 91 on the thread-dividing guide 85 independently, and disposes the threads 91 one by one in the axial region of each bobbin 90. Further, since the limit guide 60a is positioned at the limit position, the wire 91 does not move outside the axial region of the bobbin 90, and therefore, the wire 91 scattered in the axial direction can be suppressed from falling off the bobbin 90.

After the completion of the above operation, the yarn winding operation of the bobbin holder 42 on the lower winding portion 10 is performed in the same manner as the upper winding portion 10.

After the completion of the above operations in both the upper winding portion 10 and the lower winding portion 10, the operator operates the operation panel 32 to rotate and drive the platen 40 in each of the upper winding portion 10 and the lower winding portion 10, and starts the switching operation of the position of the bobbin holder 42. At the same time, the traverse guide 23 of the traverse device 21 is switched to normal high-speed drive. At substantially the same time, in each of the upper winding portion 10 and the lower winding portion 10, as shown in fig. 10, the operator rotates the opening/closing wire guide 80 to return to the original position. In other words, the wire removal guide 84 and the split guide 85 are returned to the retracted position. Since the threads 91 are arranged one by one in the axial region of each bobbin 90, when the thread removing thread guides 84 and the thread dividing thread guides 85 are positioned at the retracted positions, the plurality of traverse thread guides 23 hold the threads 91. When the wire 91 is held to the traversing guide 23, there is no longer a need to limit the restriction of the wire 91 by the guide 60 a. The operator moves the restriction guide 60a to the retracted position. In the present embodiment, the movement locus of the limit wire guide 60a when moving from the limit position to the retracted position does not interfere with the wire dividing wire guide 85 located at the wire dividing position. Therefore, the restriction guide 60a can be moved to the retracted position without interfering with the thread-dividing guide 85. Then, the bobbin 90 of the other bobbin holder 42 is brought into contact with the contact roller 31 by switching the position of the bobbin holder 42 by rotation of the platen 40, and the yarn 91 is wound around the bobbin 90 to produce the package 92. The yarn 91 wound around the bobbin 90 of the bobbin holder 42 for the yarn winding operation is pulled out of the bobbin holder 42 together with the bobbin 90 and removed. A new bobbin 90 is mounted to one bobbin holder 42.

In the present embodiment, the upper opening/closing wire guide 80 and the lower opening/closing wire guide 80 have the same structure. Alternatively, the structure of the upper opening/closing wire guide 80 may be different from that of the lower opening/closing wire guide 80. For example, the upper opening/closing wire guide 80 may be configured as shown in fig. 11. As shown in fig. 1, the yarn path from the yarn feeding roller 100 to the lower winding section 10 is parallel or substantially parallel to the vertical direction, whereas the yarn path from the yarn feeding roller 100 to the upper winding section 10 is inclined relatively greatly with respect to the vertical direction. Therefore, even if the shutter 81 is rotated up and down after the yarn 91 is wound around the yarn dividing guide 85, the yarn 91 may not be removed from the yarn dividing guide 85 because the yarn dividing guide 85 is not retracted much with respect to the yarn 91, and the yarn 91 may not be scattered in the axial direction.

In this regard, the opening and closing wire guide 80 shown in fig. 11 can operate the wire removal wire guide 84 independently of the wire separation wire guide 85. Specifically, the opening/closing yarn guide 80 includes a 1 st opening/closing plate 81a and a 2 nd opening/closing plate 81b. The 1 st shutter 81a and the 2 nd shutter 81b are rotatably attached to the rail 83, respectively. The 1 st shutter 81a and the 2 nd shutter 81b may omit the sliding function. A thread removing guide 84 is attached to the 1 st shutter 81 a. A yarn dividing guide 85 is attached to the 2 nd shutter 81b.

As shown in the upper diagram of fig. 11, in a state where the thread removing guide 84 is located at the thread removing position and the thread dividing guide 85 is located at the thread dividing position, the thread removing guide 84 is in contact with the thread 91, but the thread dividing guide 85 is not in contact with the thread 91. Accordingly, by rotating the 1 st shutter 81a up and down in this state, the wires 91 can be spread in the axial direction. As shown in the upper diagram of fig. 11, even if the wire removal guide 84 is located at the wire removal position, the limiting guide 60a located at the limiting position interferes with the wire passage, and the wire 91 can be limited.

In the yarn winding operation, the 1 st shutter 81a rotates toward the 1 st housing 20, and the yarn removing guide 84 is positioned at the retracted position. As shown in the lower diagram of fig. 11, the restriction guide 60a located at the restriction position overlaps the wire passage even if the wire removal guide 84 is located at the retracted position. Therefore, the limiting guide 60a can limit the thread 91 even in the thread winding operation.

Next, the restriction guide 60b and the moving mechanism 70b according to embodiment 2 will be described with reference to fig. 12 and 13. In the following description, the same or similar components as those in the above embodiment are denoted by the same reference numerals in the drawings, and the description thereof may be omitted. The matters described in the above embodiment are also applicable to embodiment 2 as long as no contradiction occurs.

Embodiment 2 differs from embodiment 1 mainly in the following two points. Point 1: the restricting wire guide 60b is moved from the restricting position to the retracted position by sliding only the restricting wire guide 60b without rotating. Point 2: the operator operates the operation unit 75 to slide the limit wire guide 60b.

Next, the restriction guide 60b and the moving mechanism 70b according to embodiment 2 will be described. The limit wire guides 60b are disposed on both axial side portions of the 2 nd housing 30. Since the two restriction guides 60b are symmetrical with respect to a plane perpendicular to the axial direction, the two restriction guides 60b will be described together.

The limit wire guide 60b includes a mounting portion 61, an intermediate portion 62, and an operating portion 63. The mounting portion 61 has substantially the same structure as in embodiment 1. The intermediate portion 62 is a portion provided between the mounting portion 61 and the acting portion 63. The intermediate portion 62 is shaped along the surface of the 2 nd housing 30. The action portion 63 is provided in an orientation set up from the surface of the 2 nd casing 30. As a result, the acting portion 63 extends toward the 1 st housing 20, and therefore the acting portion 63 can be made to interfere with the wire passage.

The moving mechanism 70b of embodiment 2 includes two operation levers 73, a plurality of sliding guides 74, and two operation portions 75. The operation lever 73 is a columnar member provided in the axial direction. The two operation levers 73 are fixed so as to be unable to move relative to the two mounting portions 61, respectively. That is, the operation lever 73 is movable integrally with the restriction guide 60b.

The sliding wire guides 74 are provided in plurality in the axial direction. A through hole is formed in the sliding guide 74. The operation lever 73 is inserted into the through hole of the sliding guide 74. Thereby, the wire guide 60b and the operation rod 73 are restricted from being able to slide in the axial direction.

The operation portion 75 is provided at an end of the sliding wire guide 74. The operation portion 75 has a diameter larger than that of the sliding wire guide 74 so as to be easily grasped by an operator. The operator can slide the restriction guide 60b in the axial direction by moving the operation portion 75 in the axial direction. The two operation portions 75 are provided at the same side end portions in the axial direction to make it easy for the operator to operate. The end on the side where the operation portion 75 is provided is the end on the front side of the wire winder 1, in other words, the end on the side where the operation panel 32 is provided.

In the case where the operation portion 75 is located at the position shown by the solid line in fig. 12, the two restriction guides 60b are located at the retracted positions. At this time, the axial positions of the two operation portions 75 are the same. In order to move the two restriction guides 60b from this state to the restriction positions shown by the broken lines, it is necessary to move the two operation portions 75 in different directions in the axial direction. In embodiment 2, the operation portion 63 is located on the yarn path side of the attachment portion 61 in the axial direction perpendicular to both the restricting position and the retracted position.

Since the process of performing the yarn winding operation using the restriction yarn guide 60b and the moving mechanism 70b is substantially the same as that of the above-described embodiment, only the following supplementary explanation will be made, and the explanation of the whole yarn winding operation will be omitted. In embodiment 2, when the operator slides the opening/closing wire guide 80 to return to the original position, the wire 91 moves from the outside of the acting portion 63 of the restriction wire guide 60b over the acting portion 63 to the inside of the acting portion 63. Therefore, the outer side of the acting portion 63 has a smoothly curved shape so as to easily guide the wire 91 toward the inner side of the acting portion 63.

Next, the restriction guide 60c and the moving mechanism 70c according to embodiment 3 will be described with reference to fig. 14 and 15. The matters described in the above embodiment are also applicable to embodiment 3 as long as no contradiction occurs.

In embodiment 3, a configuration for moving the limit wire guide 60c from the limit position to the retracted position is different from embodiment 1. The limit wire guides 60c and the moving mechanism 70c are disposed on both axial side portions of the 2 nd housing 30. Since the two sets of restriction guides 60c and the movement mechanism 70c are symmetrical with respect to the plane perpendicular to the axial direction, the two sets of restriction guides 60c and the movement mechanism 70c will be described below.

As shown in fig. 14 and 15, the moving mechanism 70c includes a slide rail 71 and a connecting member 76. The slide rail 71 is a columnar member provided along the axial direction. The connecting member 76 is a member formed with a through hole. The slide rail 71 is inserted into a through hole of the coupling member 76, and serves as a support shaft member of the coupling member. Thereby, the coupling member 76 can slide along the slide rail 71. Further, since the cross section of the slide rail 71 is circular, the coupling member 76 can rotate about the slide rail 71 as a rotation center.

The limit wire guide 60c includes a mounting portion 61, an operating portion 63, and a weight portion 65. The attachment portion 61 is rotatably attached to the coupling member 76. The rotation direction of the mounting portion 61 with respect to the coupling member 76 is parallel to the rotation direction of the coupling member 76 with respect to the slide rail 71. The acting portion 63 acts on the wire 91 to regulate the wire 91, similarly to the above embodiment. The weight portion 65 is provided on the opposite side of the acting portion 63 with the attachment portion 61 interposed therebetween. The weight 65 prevents the action 63 from rotating downward.

According to this configuration, the connecting member 76 is rotated relative to the slide rail 71, so that the restriction guide 60c can be moved closer to or farther from the wire passage. Specifically, when the coupling member 76 extends from the slide rail 71 toward the yarn path side in the axial direction, the restriction guide 60c can be set at the restriction position. On the other hand, when the coupling member 76 extends from the slide rail 71 to the opposite side of the wire passage in the axial direction, the restriction guide 60c can be set at the retracted position.

When the restriction guide 60c is positioned at the restriction position, the weight 65 is supported by the movement mechanism 70c, and the acting portion 63 is thereby made substantially horizontal. On the other hand, when the restriction guide 60c is located at the retracted position, the weight portion 65 is supported by the 2 nd housing 30, and the operation portion 63 can be thereby oriented upward. This can advance and retreat the limiting guide 60c in the axial direction, and can retract the limiting guide 60c from the wire passage by the orientation of the operating portion 63.

In embodiment 3, the operation portion 63 is also located on the wire passage side of the attachment portion 61 in the axial direction in both the restricting position and the retracted position. The process of performing the yarn winding operation using the restriction yarn guide 60c and the moving mechanism 70c is the same as that of the above embodiment, and therefore, the description thereof is omitted.

As described above, the yarn winding machine 1 winds the plurality of yarns 91 fed from the yarn feeding roller 100 around the plurality of bobbins 90, respectively, to manufacture the package 92. The yarn winding machine 1 of the present embodiment includes a bobbin holder 42, a plurality of traverse guides 23, a yarn removing guide 84, limiting guides 60a, 60b, 60c, and moving mechanisms 70a, 70b, 70c. The bobbin holder 42 holds a plurality of bobbins 90. The traverse guide 23 contacts the plurality of wires 91 to traverse the wires 91 in the bobbin holder axial direction. The wire removal guide 84 holds the wires 91 in a state where the plurality of wires 91 are removed from the plurality of traverse guides 23. The limiting guides 60a, 60b, 60c are disposed so as to correspond to both side portions of the axial regions of the plurality of bobbins 90, respectively, limit the plurality of wires 91 held by the wire removing guide 84, and limit the wires 91 so that the positions of the wire 91 in the bobbin holder axial direction are inside the axial regions of the plurality of bobbins 90 held by the bobbin holder 42. The movement mechanisms 70a, 70b, 70c can move the restriction guides 60a, 60b, 60c between a restriction position for restricting the wire 91 and a retracted position retracted from the restriction position by acting on the wire 91. The wire removal guide 84 is movable between a holding position where the plurality of wires 91 are held and a retracted position retracted from the holding position. When the portion of the limiting guides 60a, 60b, 60c attached to the moving mechanisms 70a, 70b, 70c is the attachment portion 61, the portion acting on the wire 91 is the acting portion 63, the direction in which the wire feeding roller 100 is located with respect to the wire winder 1 is the height direction, and the direction orthogonal to both the height direction and the bobbin holder axial direction is the axis orthogonal direction, the acting portion 63 is located on the wire passage side of the attachment portion 61 in the axis orthogonal direction at both the limiting position and the retracted position.

Accordingly, since the limiting guides 60a, 60b, and 60c limit the thread 91 to the inner side of the region in the axial direction of the bobbin 90, the thread 91 can be prevented from being unraveled when the thread 91 is removed from the traverse guide 23. Therefore, the yarn winding operation of winding the yarn 91 around the bobbin holder 42 can be easily performed. In addition, when the limiting wire 91 is not required, the limiting wire guides 60a, 60b, 60c are required to be moved to the retracted positions, so that the processing is easier than the configuration requiring attachment and detachment. Further, the restricting guides 60a, 60b, 60c can be moved between the restricting position and the retracted position without largely changing the posture of the restricting guides 60a, 60b, 60 c. Therefore, the movement paths of the limit guides 60a, 60b, 60c are reduced, and thus the arrangement space of other components can be enlarged. Further, the yarn 91 can be suppressed from being scattered in the case where the yarn 91 is removed from the traverse device 21, and thus yarn drop is difficult to occur. As a result, the occurrence of yarn breakage due to yarn breakage can be suppressed.

In the wire winding machine 1 of the present embodiment, the moving mechanisms 70a, 70b, 70c have a mechanism for axially sliding the limiting guides 60a, 60b, 60c along the bobbin holder at least inside the axial region of the plurality of bobbins 90.

In the yarn winding operation, the winding positions of the yarn 91 limited by the limiting guides 60a, 60b, 60c can be dispersed by sliding the limiting guides 60a, 60b, 60c positioned at the limiting positions.

In the wire winding machine 1 of the present embodiment, the restricting positions and the retracted positions of the restricting guides 60a and 60b are switched by restricting the guides 60a and 60b to slide along the bobbin holder in the axial direction.

This allows the restricting position and the retracted position to be switched by a simple operation with a small movement locus.

The wire winding machine 1 of the present embodiment includes an operation unit 75, and the operation unit 75 is disposed on the end side in the axial direction of the bobbin holder with respect to the limiting wire guide 60b and is coupled to the limiting wire guide 60b, so that the limiting wire guide 60b can be slid.

This allows the restriction guide to be easily slid as compared with the case where the restriction guide 60b is directly contacted and operated.

In the wire winder 1 of the present embodiment, the operation portion 63 is moved in the height direction in a direction in which the operation portion 63 is away from the yarn feeding roller 100, whereby the limit yarn guide 60a is switched from the limit position to the retracted position.

This makes it difficult to prevent other devices from operating.

In the wire winding machine 1 of the present embodiment, the moving mechanism 70a includes a support rail 72, and the support rail 72 is provided along the bobbin holder axial direction and supports the limiting wire guide 60a so that the limiting wire guide 60a maintains the limiting position. The limit wire guide 60a is capable of sliding along the support rail 72 in the spool support axial direction. The restricting wire guide 60a slides over the portion where the support rail 72 is arranged, and is switched from the restricting position to the retracted position.

This allows sharing of the sliding-assisting member with the member for maintaining the restricting position of the wire guide 60 a. Further, the switching from the restricting position to the retracted position can be performed easily.

In the yarn winding machine 1 of the present embodiment, the moving mechanism 70c includes the slide rail 71 and the connecting member 76 connecting the slide rail 71 and the restricting yarn guide 60 c. In the restricting position, the connecting member 76 extends from the slide rail 71 toward the wire passage side in the axial orthogonal direction. In the retracted position, the coupling member 76 extends from the slide rail 71 to the opposite side of the wire path in the axial orthogonal direction.

This can reduce the movement locus of the restriction guide 60c compared with a configuration in which the restriction guide 60c itself is reversed.

The yarn winding machine 1 of the present embodiment includes a 1 st housing 20 and a 2 nd housing 30. The 1 st housing 20 is provided with a traverse device 21. The 2 nd casing 30 is disposed opposite to the 1 st casing 20 through the yarn path. The thread removing guide is disposed in the 1 st housing. The limit guides 60a, 60b, 60c are disposed in the 2 nd housing 30.

Thereby, the wire removal guide 84 and the restriction guides 60a, 60b, 60c can be appropriately arranged.

The yarn winding machine 1 of the present embodiment includes a yarn dividing guide 85, and the yarn dividing guide 85 individually separates and holds the yarn 91 in each of the traverse regions of the plurality of traverse guides 23. The yarn dividing guide 85 is movable between a yarn dividing position for dividing and holding the plurality of yarns 91 and a retracted position retracted from the yarn dividing position.

Accordingly, the plurality of wires 91 can be guided to the traverse regions of the traverse guides 23 while the plurality of wires 91 are restricted by the restricting guides 60a, 60b, and 60c, and the wire winding operation can be facilitated by bringing the wires into contact (engagement) with the traverse guides 23.

In the yarn winding machine 1 of the present embodiment, the spacing between the plurality of yarns on the bobbin holder 42 is smaller than the spacing between the plurality of yarns on the yarn feeding roller 100.

When the pitch between the plurality of wires on the bobbin holder 42 is smaller than the pitch between the plurality of wires on the yarn feeding roller 100, the plurality of wires 91 tend to spread out over a wider range than the axial regions of the plurality of bobbins 90 held by the bobbin holder 42, and therefore the effect of restricting the yarn guides 60a, 60b, 60c can be effectively exhibited.

The preferred embodiments of the present invention have been described above, but the above-described configuration can be modified as follows.

In the yarn winding machine 1 of the above embodiment, the winding sections 10 are arranged vertically. Alternatively, the winding units 10 may be arranged in a horizontal direction, or 1 winding unit 10 may be provided in the wire winder 1.

The traverse device 21 of the above embodiment is of a cam roller type, but may be of a different configuration as long as the traverse guide 23 can be reciprocated in the winding width direction. For example, a belt-type traverse device may be used instead of the traverse device 21.
