Description

纖維機械 Fiber Machinery

本發明係關於用於製造或加工由合成纖維構成的紗線的纖維機械。 The present invention relates to a fiber machine for manufacturing or processing yarns made of synthetic fibers.

在例如專利文獻1中揭示的假撚加工機這樣的對紗線進行加工的纖維機械中，對沿著紗道行進的紗線實施加工。因此，在行進的紗線接觸的部位，由於與紗線的摩擦而產生靜電。但是，由於靜電一般不會帶來致命的影響，因此，迄今為止，在纖維機械中沒有特別採取防靜電對策。 For example, in a textile machine that processes yarns, such as a false twisting machine disclosed in Patent Document 1, the yarns traveling along the yarn path are processed. Therefore, static electricity is generated due to friction with the yarn at the position where the traveling yarn comes into contact. However, since static electricity generally does not bring about a fatal effect, so far, no special anti-static measures have been taken in textile machinery.

[專利文獻1]日本特開2007-277751號公報 [Patent Document 1] JP 2007-277751 A

但是，有關對纖維機械的加工品質、作業性的要求逐年增加，近年來，靜電的影響已變成不容忽視。具體為，由於靜電的影響會使紗線行進變得不穩定，掛紗性降低，或者因導致紗線搖擺而容易產生斷紗、作業性惡化的問題。此外，由於靜電的影響而使紗線的行進變得不穩定，紗線變成不在本來的紗道行進，因此不能夠對紗線 實施適當的加工，存在紗線的品質降低的風險。 However, the requirements for processing quality and workability of textile machinery are increasing year by year, and in recent years, the influence of static electricity has become indispensable. Specifically, due to the influence of static electricity, the yarn travel becomes unstable and the yarn hangability is reduced, or the yarn is swayed, which tends to cause yarn breakage and deterioration of workability. In addition, the travel of the yarn becomes unstable due to the influence of static electricity, and the yarn does not travel in the original yarn path, so the yarn cannot be With proper processing, there is a risk that the quality of the yarn will decrease.

本發明就是鑒於以上的問題而開發完成的，其目的是在用於製造或加工由合成纖維構成的紗線的纖維機械中，抑制迄今為止沒有採取對策的靜電的影響、使紗線的行進穩定化。 The present invention was developed in view of the above problems, and its purpose is to suppress the influence of static electricity, which has not been countermeasured up to now, in a textile machine used to manufacture or process yarns made of synthetic fibers, and to stabilize yarn travel. change.

本發明為用於製造或加工由合成纖維構成的紗線的纖維機械，其特徵在於，設置有用來從帶電部位將靜電除去的靜電去除機構，該帶電部位是因前述紗線在接觸狀態下行進而產生靜電。 The present invention is a fiber machine for manufacturing or processing yarns made of synthetic fibers. It is characterized in that it is provided with a static electricity removing mechanism for removing static electricity from a charged part, which is caused by the yarn running in a contact state. Generate static electricity.

根據本發明，由於對帶電部位設置靜電去除機構，因此能夠抑制帶電部位靜電的影響，能夠使紗線的行進穩定化。 According to the present invention, since the static electricity removing mechanism is provided in the charged part, the influence of static electricity in the charged part can be suppressed, and the running of the yarn can be stabilized.

並且，在本發明中，前述帶電部位為一邊與前述紗線接觸一邊旋轉的旋轉體，對前述旋轉體設置前述靜電去除機構。 In addition, in the present invention, the charged portion is a rotating body that rotates while being in contact with the yarn, and the static electricity removing mechanism is provided to the rotating body.

這種情況下，雖然因紗線與旋轉體的摩擦而產生靜電，但由於對旋轉體設置有靜電去除機構，因此能夠防止靜電積累在旋轉體上。 In this case, although the friction between the yarn and the rotating body generates static electricity, since the static electricity removing mechanism is provided to the rotating body, it is possible to prevent static electricity from accumulating on the rotating body.

並且，在本發明中，作為前述旋轉體係具備：輸送前述紗線的高速喂紗輥、以及低速喂紗輥，該低速喂紗輥，是配置在比前述高速喂紗輥更靠紗線行進方向下游側，為了使前述紗線在其與前述高速喂紗輥之間鬆弛 而以比前述高速喂紗輥更慢的輸送速度輸送前述紗線；至少對前述高速喂紗輥設置前述靜電去除機構。 In addition, in the present invention, as the rotating system, a high-speed yarn feeding roller for conveying the yarn and a low-speed yarn feeding roller are provided, and the low-speed yarn feeding roller is arranged closer to the yarn traveling direction than the high-speed yarn feeding roller. On the downstream side, in order to slack the aforementioned yarn and the aforementioned high-speed yarn feeding roller The yarn is conveyed at a slower conveying speed than the high-speed yarn feeding roller; at least the static electricity removing mechanism is provided for the high-speed yarn feeding roller.

當在高速喂紗輥與低速喂紗輥之間使紗線鬆弛的情況下，由於積累在紗線行進方向上游側的高速喂紗輥上的靜電的影響，在其紗線行進方向下游側鬆弛的紗線的行進容易變得不穩定。因此，藉由對高速喂紗輥設置靜電去除機構，能夠使鬆弛的紗線的行進穩定化。 When the yarn is slackened between the high-speed yarn feeding roller and the low-speed yarn feeding roller, due to the influence of static electricity accumulated on the high-speed yarn feeding roller on the upstream side of the yarn traveling direction, the yarn is slackened on the downstream side of the yarn traveling direction. The travel of the yarn tends to become unstable. Therefore, by providing a static electricity removal mechanism to the high-speed yarn feeding roller, the running of the slack yarn can be stabilized.

例如，在前述高速喂紗輥的紗線行進方向上游側設置對前述紗線賦予撚的加撚裝置，並在紗線行進方向上於前述高速喂紗輥與前述低速喂紗輥之間設置對前述紗線進行加熱的加熱裝置的情況下，由於藉由加熱裝置加熱的紗線為鬆弛狀態，因此對高速喂紗輥設置靜電去除機構是有效的。 For example, a twisting device for imparting twist to the yarn is installed on the upstream side of the yarn traveling direction of the high-speed yarn feeding roller, and a pair is installed between the high-speed yarn feeding roller and the low-speed yarn feeding roller in the yarn traveling direction. In the case of the heating device for heating the yarn, since the yarn heated by the heating device is in a relaxed state, it is effective to provide a static electricity removal mechanism to the high-speed yarn feeding roller.

除此以外，在紗線行進方向上於前述高速喂紗輥與前述低速喂紗輥之間設置有對前述紗線賦予交織的交織裝置的情況下，由於藉由交織裝置賦予交織的紗線處於鬆弛狀態，因此對高速喂紗輥設置靜電去除機構是有效的。 In addition, when an interlacing device for imparting interlacing to the yarn is provided between the high-speed yarn feeding roller and the low-speed yarn feeding roller in the yarn traveling direction, the yarn interlaced by the interlacing device is placed in In a relaxed state, it is effective to install a static electricity removal mechanism on the high-speed yarn feeding roller.

並且，在本發明中，前述靜電去除機構也可以以不與前述旋轉體接觸的形態設置。 In addition, in the present invention, the static electricity removing mechanism may be provided in a form that does not contact the rotating body.

在靜電去除機構與旋轉體接觸的情況下，由於靜電去除機構、旋轉體磨損，存在不能夠適當地將靜電除去，或者零件更換頻率增多的風險。並且，由於靜電去除機構與旋轉體接觸，存在反而增加靜電去除機構與旋轉 體之間產生的靜電量的風險。但是，在靜電去除機構不與旋轉體接觸的情況下，能夠避免這樣的問題。 When the static electricity removal mechanism is in contact with the rotating body, there is a risk that static electricity cannot be properly removed due to the wear of the static electricity removal mechanism and the rotating body, or the frequency of parts replacement increases. Moreover, since the static electricity removal mechanism is in contact with the rotating body, there is an increase in the static electricity removal mechanism and the rotating body. The risk of the amount of static electricity generated between the bodies. However, when the static electricity removing mechanism is not in contact with the rotating body, such a problem can be avoided.

並且，在本發明中，前述旋轉體可以構成為具有：旋轉軸、和安裝在前述旋轉軸上且使前述紗線與其外周面接觸的輥；對前述旋轉軸設置前述靜電去除機構。 In addition, in the present invention, the rotating body may be configured to have a rotating shaft and a roller mounted on the rotating shaft to bring the yarn into contact with the outer peripheral surface thereof; and the static electricity removing mechanism is provided to the rotating shaft.

藉由對旋轉軸設置靜電去除機構，與對輥設置的情況相比，能夠抑制靜電去除機構朝向徑向的大型化，能夠成為緊緻的結構。 By providing the static electricity removal mechanism on the rotating shaft, compared with the case where the static electricity removal mechanism is installed on the roller, it is possible to suppress the increase in the size of the static electricity removal mechanism in the radial direction, and it is possible to have a compact structure.

並且，在本發明中，前述靜電去除機構可以具有被接地的支承構件、和以沿著前述旋轉軸的外周面的方式安裝在前述支承構件上的靜電消除構件。 In addition, in the present invention, the static electricity removing mechanism may include a support member that is grounded, and a static electricity removing member mounted on the support member so as to be along the outer peripheral surface of the rotating shaft.

藉由以沿著旋轉軸的外周面的方式設置靜電消除構件，能夠確保寬闊的從旋轉軸向靜電消除構件放電的區域，能夠更確實地除去靜電。 By providing the static elimination member along the outer peripheral surface of the rotating shaft, a wide area where the static elimination member is discharged from the rotating shaft can be secured, and static electricity can be removed more reliably.

並且，在本發明中，前述靜電消除構件可以沿著前述旋轉軸的軸向設置。 Furthermore, in the present invention, the static elimination member may be provided along the axial direction of the rotating shaft.

如果這樣，能夠抑制軸向上靜電消除性能的偏差，能夠適當地進行靜電消除。 In this way, the deviation of the static elimination performance in the axial direction can be suppressed, and the static elimination can be performed appropriately.

並且，在本發明中，前述靜電消除構件的導電性纖維可以在多個部位露出於表面。 In addition, in the present invention, the conductive fibers of the static elimination member may be exposed on the surface at a plurality of locations.

藉由使用這樣的靜電消除構件，由於在導電性纖維露出的多個部位發生放電，因此能夠提高靜電消除構件的靜電消除性能。 By using such a static elimination member, since discharge occurs at a plurality of locations where the conductive fibers are exposed, the static elimination performance of the static elimination member can be improved.

並且，在本發明中，為了避免前述靜電消除 構件露出，可以設置覆蓋前述靜電消除構件周圍的蓋構件。 Moreover, in the present invention, in order to avoid the aforementioned static elimination The member is exposed, and a cover member may be provided to cover the periphery of the aforementioned static elimination member.

若靜電消除構件上附著了塵埃等，則向靜電消除構件的放電變得不易發生，存在放電性能降低的風險。但是，藉由像上述那樣設置蓋構件，能夠抑制塵埃等向靜電消除構件的附著，能夠避免放電性能的降低。 If dust or the like adheres to the static elimination member, discharge to the static elimination member becomes less likely to occur, and there is a risk that the discharge performance is reduced. However, by providing the cover member as described above, it is possible to suppress adhesion of dust and the like to the static elimination member, and it is possible to avoid a decrease in discharge performance.

並且，在本發明中，也可以對由尼龍製作的前述紗線進行加工。 Furthermore, in the present invention, the aforementioned yarn made of nylon may be processed.

在加工尼龍製的紗線的情況下，由於與帶電部位的摩擦而特別容易產生靜電。因此，設置靜電去除機構的效果變得更加顯著。 In the case of processing nylon yarns, it is particularly easy to generate static electricity due to friction with charged parts. Therefore, the effect of providing a static electricity removal mechanism becomes more significant.

The third yarn feeding roller 18 is configured such that a plurality of driving rollers and driven rollers, not shown, which are independently provided for the interlaced yarns Y provided by the interlacing device 17 are arranged in a row along the longitudinal direction of the machine table. . In addition, the conveying speed of the yarn Y by the third yarn feeding roller 18 is slower than the conveying speed of the yarn Y by the second yarn feeding roller 16. In the meantime, the yarn Y is slackened.

第2加熱裝置19為用來對從第3喂紗輥18送來的紗線Y進行加熱的裝置，在主機台5中配置於第3喂紗輥18的下方。第2加熱裝置19沿豎直方向延伸，每一個跨度設置一個。 The second heating device 19 is a device for heating the yarn Y sent from the third yarn feeding roller 18, and is arranged below the third yarn feeding roller 18 in the main machine table 5. The second heating device 19 extends in the vertical direction, one for each span.

The fourth yarn feeding roller 20 is configured such that a plurality of driving rollers and driven rollers, not shown, which are independently provided for the plurality of yarns Y heat-treated by the second heating device 19, are arranged in a row along the longitudinal direction of the machine table. Row. In addition, by The conveying speed of the yarn Y of the fourth yarn feeding roller 20 is slower than the conveying speed of the yarn Y passing through the third yarn feeding roller 18, and the yarn is made between the third yarn feeding roller 18 and the fourth yarn feeding roller 20. Y relaxes.

像上述那樣構成的加工部3，藉由加撚裝置15對在第1喂紗輥11與第2喂紗輥16之間被拉伸的紗線Y賦予撚。由加撚裝置15形成的撚傳播到止撚導絲器12，但傳播不到比止撚導絲器12更靠紗線行進方向上游側。被拉伸並被賦予撚後的紗線Y藉由第1加熱裝置13加熱後，由冷卻裝置14冷卻而被熱定型。假撚後的紗線Y通過加撚裝置15後，在到達第2喂紗輥16之前被解撚，由於紗線Y的撚像上述那樣被熱定型了，因此各細絲維持波形的假撚後的狀態。而且，紗線Y一邊在第2喂紗輥16與第3喂紗輥18之間被鬆弛，一邊藉由交織裝置17賦予交織。被賦予交織後的紗線Y一邊在第3喂紗輥18與第4喂紗輥20之間被鬆弛，一邊藉由第2加熱裝置19熱定型。最後，從第4喂紗輥20送來的紗線Y藉由捲繞裝置21捲繞而形成卷裝P。 The processing section 3 configured as described above imparts twists to the yarn Y drawn between the first yarn supplying roller 11 and the second yarn supplying roller 16 by the twisting device 15.

(加撚裝置) (Twisting device)

圖2為表示加撚裝置15的結構的示意圖。本實施方式的加撚裝置15為所謂摩擦盤式裝置，採用在3根心軸31上安裝摩擦盤32的結構。在各心軸31上沿心軸的軸向隔開間隔設置有2個摩擦盤32。在各心軸31間，摩擦盤32在心軸的軸向上的位置互相錯開。並且，3根心軸 31配置成，從心軸的軸向觀察時，其中心分別位於等邊三角形的頂點。結果，加撚裝置15構成為多個(本實施方式中為6個)摩擦盤32配置成螺旋狀。 FIG. 2 is a schematic diagram showing the structure of the twisting device 15. The twisting device 15 of the present embodiment is a so-called friction disc type device, and adopts a structure in which friction discs 32 are mounted on three mandrels 31. Two friction discs 32 are provided on each mandrel 31 at an interval along the axial direction of the mandrel. Between the spindles 31, the positions of the friction discs 32 in the axial direction of the spindles are staggered from each other. And, 3 mandrels 31 is arranged so that when viewed from the axial direction of the mandrel, its centers are located at the vertices of an equilateral triangle. As a result, the twisting device 15 is configured such that a plurality of (six in this embodiment) friction discs 32 are arranged in a spiral shape.

當驅動未圖示的電動機時，各心軸31旋轉，且摩擦盤32與各心軸31一體地旋轉。而且，紗線Y與正在旋轉的摩擦盤32的周面接觸，並且在多個摩擦盤32之間沿大致心軸的軸向行進，藉由這樣對紗線Y賦予撚。 When a motor (not shown) is driven, each spindle 31 rotates, and the friction disc 32 rotates integrally with each spindle 31. In addition, the yarn Y is in contact with the peripheral surface of the rotating friction disk 32 and travels between the plurality of friction disks 32 substantially in the axial direction of the mandrel, thereby imparting twist to the yarn Y.

(靜電的影響) (Effect of static electricity)

在像上述那樣構成的假撚加工機1中，會發生在第3喂紗輥18與第4喂紗輥20之間掛紗失敗、紗線搖擺大、斷紗的產生率高這樣的問題。本發明人對這個問題反復進行了深入的研究，結果發現是因為積累在第3喂紗輥18上的靜電的原因。實際上如果從第3喂紗輥18上除去靜電的話，則第3喂紗輥18上生成的電壓從約1500伏特下降到100伏特以下，能夠使第3喂紗輥18與第4喂紗輥20之間紗線Y的行進穩定化。結果，由於能夠提高掛紗性，並且藉由抑制斷紗的產生而能夠提高作業性。並且，由於紗線Y的行進穩定，也能夠期待紗線Y的品質提高。 In the false twisting machine 1 configured as described above, problems such as failure of yarn hooking between the third yarn supply roller 18 and the fourth yarn supply roller 20, large yarn sway, and high rate of occurrence of yarn breakage occur. The inventor of the present invention has repeatedly conducted intensive research on this problem, and found that it is due to static electricity accumulated on the third yarn feeding roller 18. In fact, if the static electricity is removed from the third yarn supplying roller 18, the voltage generated on the third yarn supplying roller 18 will drop from about 1500 volts to 100 volts or less, which can make the third yarn supplying roller 18 and the fourth yarn supplying roller 18 The travel of the yarn Y between 20 is stabilized. As a result, the yarn hanging property can be improved, and the workability can be improved by suppressing the occurrence of yarn breakage. In addition, since the running of the yarn Y is stable, the quality of the yarn Y can also be expected to improve.

本實施方式的假撚加工機1考慮到上述研究結果，對第3喂紗輥18設置了靜電去除機構。下面對設置在第3喂紗輥18上的靜電去除機構進行說明。另外，這樣的靜電去除機構不僅對第3喂紗輥18，對由於靜電 而產生不良影響的假撚加工機1的所有帶電部位都能夠設置。 In the false twisting machine 1 of the present embodiment, in consideration of the above-mentioned research results, the third yarn feeding roller 18 is provided with a static electricity removing mechanism. Next, the static electricity removing mechanism provided on the third yarn feeding roller 18 will be described. In addition, such a static electricity removing mechanism not only affects the third yarn feeding roller 18, but also affects the static electricity. All the charged parts of the false twisting machine 1 that have an adverse effect can be installed.

(靜電去除機構) (Static removal mechanism)

圖3和圖4為第3喂紗輥18的局部立體圖。更詳細為，圖3表示組裝了覆蓋旋轉軸43的蓋構件45、覆蓋靜電去除機構50的蓋構件60的狀態，旋轉軸43、靜電去除機構50變成看不見。另一方面，圖4表示卸下了蓋構件45、60，旋轉軸43、靜電去除機構50露出的狀態。另外，圖4省略了從動輥42、支承支架44的圖示。 3 and 4 are partial perspective views of the third yarn feeding roller 18. As shown in FIG. In more detail, FIG. 3 shows a state where the cover member 45 covering the rotating shaft 43 and the cover member 60 covering the static electricity removing mechanism 50 are assembled, and the rotating shaft 43 and the static electricity removing mechanism 50 are invisible. On the other hand, FIG. 4 shows a state where the cover members 45 and 60 are removed, and the rotating shaft 43 and the static electricity removing mechanism 50 are exposed. In addition, the illustration of the driven roller 42 and the support bracket 44 is omitted in FIG. 4.

第3喂紗輥18具有：由未圖示的驅動電動機旋轉驅動的驅動輥41、和與驅動輥41接觸且伴隨驅動輥41的旋轉而旋轉的從動輥42。驅動輥41由金屬、即導電性材料構成，從動輥42由橡膠、即絕緣性材料構成。並且，紗線Y(圖3和圖4中未圖示)被夾在驅動輥41與從動輥42之間，當驅動輥41沿既定方向旋轉時，紗線Y被送往紗線行進方向下游側。 The third yarn feeding roller 18 includes a drive roller 41 that is rotationally driven by a drive motor (not shown), and a driven roller 42 that is in contact with the drive roller 41 and rotates in accordance with the rotation of the drive roller 41. The driving roller 41 is made of metal, that is, a conductive material, and the driven roller 42 is made of rubber, that is, an insulating material. And, the yarn Y (not shown in FIGS. 3 and 4) is sandwiched between the driving roller 41 and the driven roller 42, and when the driving roller 41 rotates in a predetermined direction, the yarn Y is sent to the yarn traveling direction The downstream side.

驅動輥41在沿著機台長度方向延伸的旋轉軸43(參照圖4)上安裝有多個。即，多個驅動輥41由共同的旋轉軸43支承。旋轉軸43在上述驅動電動機的驅動下旋轉，藉由旋轉軸43旋轉，多個驅動輥41旋轉。旋轉軸43也與驅動輥41同樣，由金屬即導電性材料構成。從動輥42是與多個驅動輥41相對應地沿機台長度方向設置多根。各從動輥42由獨立地設置的支承支架44和未圖示 的軸承可旋轉地支承著。 A plurality of driving rollers 41 are attached to a rotating shaft 43 (refer to FIG. 4) extending in the longitudinal direction of the machine base. That is, the plurality of driving rollers 41 are supported by the common rotating shaft 43. The rotating shaft 43 rotates by the drive of the above-mentioned drive motor, and the rotation of the rotating shaft 43 causes the plurality of drive rollers 41 to rotate. The rotating shaft 43 is also made of a conductive material that is metal, similarly to the driving roller 41. A plurality of driven rollers 42 are provided in the longitudinal direction of the machine table corresponding to the plurality of driving rollers 41. Each driven roller 42 consists of an independent support bracket 44 and not shown The bearings are rotatably supported.

在第3喂紗輥18中，與紗線Y的摩擦而產生的靜電難以移動到作為絕緣性構件的從動輥42，因此移動到作為導電性構件的驅動輥41上，能夠進一步經由驅動輥41而移動到作為導電性構件的旋轉軸43上。其中，旋轉軸43藉由未圖示的軸承可旋轉地支承著。支承從動輥42的軸承和支承旋轉軸43的軸承為了潤滑而使用了絕緣性的潤滑油，靜電難以經由這些軸承釋放。因此，由導電性材料構成的驅動輥41、旋轉軸43特別容易積累靜電。 In the third yarn feeding roller 18, the static electricity generated by friction with the yarn Y is difficult to move to the driven roller 42 as an insulating member, so it moves to the driving roller 41 as a conductive member and can further pass through the driving roller. 41 moves onto the rotating shaft 43 as a conductive member. Among them, the rotating shaft 43 is rotatably supported by a bearing (not shown). The bearing supporting the driven roller 42 and the bearing supporting the rotating shaft 43 use insulating lubricating oil for lubrication, and it is difficult for static electricity to be discharged via these bearings. Therefore, the drive roller 41 and the rotating shaft 43 made of a conductive material are particularly likely to accumulate static electricity.

因此，本實施方式中像圖4所示那樣，為了從旋轉軸43將靜電除去，在旋轉軸43附近設置有由支承構件51和靜電消除構件52構成的靜電去除機構50。圖5為表示靜電去除機構50和蓋構件60的安裝形態的剖視圖，為示意地圖示了與機台長度方向正交的截面的圖。 Therefore, in this embodiment, as shown in FIG. 4, in order to remove static electricity from the rotating shaft 43, a static electricity removing mechanism 50 composed of a supporting member 51 and a static electricity removing member 52 is provided in the vicinity of the rotating shaft 43. 5 is a cross-sectional view showing how the static electricity removing mechanism 50 and the cover member 60 are attached, and is a diagram schematically illustrating a cross section perpendicular to the longitudinal direction of the machine base.

靜電去除機構50由固定在構成主機台5的金屬製的框體5a上的金屬製的支承構件51和安裝在支承構件51上的靜電消除構件52構成。支承構件51由於固定在框體5a上，經由框體5a被間接地接地。另外，也可以使支承構件51直接接地。 The static electricity removal mechanism 50 is composed of a metal support member 51 fixed to a metal frame 5 a constituting the main table 5 and a static electricity elimination member 52 attached to the support member 51. Since the support member 51 is fixed to the frame 5a, it is indirectly grounded via the frame 5a. In addition, the supporting member 51 may be directly grounded.

如圖5所示，支承構件51具有：用螺栓固定在框體5a上的固定部51a、保持靜電消除構件52的保持部51b、連接固定部51a和保持部51b的連接部51c、供安裝後述的蓋構件60的蓋安裝部51d。 As shown in FIG. 5, the support member 51 has: a fixing portion 51a that is bolted to the frame 5a, a holding portion 51b that holds the static elimination member 52, a connecting portion 51c that connects the fixing portion 51a and the holding portion 51b, and is used for mounting as described later. The cover mounting portion 51d of the cover member 60.

固定部51a與保持部51b彼此相對向，旋轉軸43位於固定部51a與保持部51b之間。保持部51b具有沿著旋轉軸43的軸向延伸的平板形狀，配置在離旋轉軸43的上端部(頂部)往上方5mm~10mm左右的位置上。靜電消除構件52為導電性纖維在多個部位露出於表面的構件。這樣一來，藉由沿著旋轉軸43設置靜電消除構件52，能夠在許多部位從旋轉軸43朝向靜電消除構件52產生放電，能夠有效地將靜電從旋轉軸43除去。根據以上的結構，因與紗線Y的接觸而在第3喂紗輥18上產生的靜電經由驅動輥41、旋轉軸43、靜電消除構件52、支承構件51和框體5a而放電。另外，使支承構件51和靜電消除構件52都不與旋轉軸43接觸。 The fixed portion 51a and the holding portion 51b are opposed to each other, and the rotating shaft 43 is located between the fixed portion 51a and the holding portion 51b. The holding portion 51b has a flat plate shape extending along the axial direction of the rotating shaft 43, and is arranged at a position approximately 5 mm to 10 mm upward from the upper end (top) of the rotating shaft 43. The static elimination member 52 is a member in which conductive fibers are exposed on the surface at a plurality of locations. In this way, by providing the static elimination member 52 along the rotating shaft 43, discharge can be generated from the rotating shaft 43 toward the static elimination member 52 at many places, and static electricity can be effectively removed from the rotating shaft 43. According to the above configuration, static electricity generated on the third yarn feed roller 18 due to contact with the yarn Y is discharged via the drive roller 41, the rotating shaft 43, the static elimination member 52, the support member 51, and the frame 5a. In addition, neither the support member 51 nor the static elimination member 52 is in contact with the rotating shaft 43.

固定在框體5a上的靜電去除機構50，其周邊被蓋構件60覆蓋。蓋構件60形成為大致U字形，具有覆蓋靜電去除機構50的蓋部60a和在蓋部60a的一個端部折彎成近似直角的固定部60b。蓋構件60將固定部60b用螺栓固定在框體5a上，同時將蓋部60a的另一個端部用螺栓固定在支承構件51的蓋安裝部51d上。如圖3所示，蓋部60a的外周面構成為，在徑向上大致位於與驅動輥41的外周面相同的位置上，而使靜電去除機構50、蓋構件60不致比驅動輥41朝向徑向外側太突出。 The periphery of the static electricity removing mechanism 50 fixed to the frame 5 a is covered by the cover member 60. The cover member 60 is formed in a substantially U-shape, and has a cover part 60a covering the static electricity removing mechanism 50 and a fixing part 60b bent at an approximately right angle at one end of the cover part 60a. The cover member 60 fixes the fixing portion 60b to the frame 5a with bolts, and at the same time fixes the other end of the cover portion 60a to the cover mounting portion 51d of the support member 51 with bolts. As shown in FIG. 3, the outer peripheral surface of the cover portion 60a is configured to be located at approximately the same position as the outer peripheral surface of the drive roller 41 in the radial direction, so that the static electricity removing mechanism 50 and the cover member 60 do not face radially from the drive roller 41. The outside is too protruding.

(效果) (Effect)

根據本實施方式，由於設置從因紗線Y在接觸的狀態 下行進而產生靜電的帶電部位(第3喂紗輥18)將靜電除去的靜電去除機構50，因此能夠抑制帶電部位的靜電的影響，能夠使紗線Y的行進穩定化。 According to this embodiment, due to the setting, the yarn Y is in contact with The static electricity removing mechanism 50 that removes static electricity from the charged portion (third yarn feed roller 18) that generates static electricity further down, can suppress the influence of static electricity at the charged portion and stabilize the travel of the yarn Y.

並且，在本實施方式中，上述帶電部位為紗線Y一邊行進一邊接觸的旋轉體(第3喂紗輥18)，對旋轉體設置有靜電去除機構50。這種情況下，因紗線Y與旋轉體的摩擦而產生靜電，但由於對旋轉體設置靜電去除機構50，能夠防止靜電積累在旋轉體上。 In addition, in the present embodiment, the charged portion is a rotating body (third yarn feed roller 18) that the yarn Y contacts while traveling, and a static electricity removing mechanism 50 is provided to the rotating body. In this case, static electricity is generated due to friction between the yarn Y and the rotating body, but since the static electricity removing mechanism 50 is provided to the rotating body, it is possible to prevent static electricity from accumulating on the rotating body.

並且，在本實施方式中，作為上述旋轉體係具備：輸送紗線Y的高速喂紗輥(第3喂紗輥18)、和低速喂紗輥(第4喂紗輥20)，低速喂紗輥配置在比高速喂紗輥更靠紗線行進方向下游側，為了使紗線Y在其與高速喂紗輥之間鬆弛而以比高速喂紗輥更慢的輸送速度輸送紗線Y，至少對高速喂紗輥設置靜電去除機構50。這樣，在紗線Y在高速喂紗輥與低速喂紗輥之間被鬆弛的情況下，由於積累在紗線行進方向上游側的高速喂紗輥上的靜電的影響，在該紗線行進方向下游側鬆弛的紗線Y的行進容易變得不穩定。因此，藉由對高速喂紗輥設置靜電去除機構50，能夠使鬆弛的紗線Y的行進穩定化。 In addition, in the present embodiment, as the above-mentioned rotating system, a high-speed yarn feeding roller (third yarn feeding roller 18) for conveying the yarn Y, a low-speed yarn feeding roller (fourth yarn feeding roller 20), and a low-speed yarn feeding roller are provided. It is arranged on the downstream side of the yarn traveling direction than the high-speed feed roller. In order to loosen the yarn Y between the high-speed feed roller and the yarn Y, the yarn Y is transported at a slower transport speed than the high-speed feed roller. The high-speed yarn feeding roller is provided with a static electricity removing mechanism 50. In this way, when the yarn Y is loosened between the high-speed yarn feeding roller and the low-speed yarn feeding roller, due to the influence of static electricity accumulated on the high-speed yarn feeding roller on the upstream side of the yarn traveling direction, the yarn Y The running of the yarn Y slack on the downstream side tends to become unstable. Therefore, by providing the static electricity removing mechanism 50 to the high-speed yarn feeding roller, the traveling of the slack yarn Y can be stabilized.

並且，在本實施方式中，在高速喂紗輥(第3喂紗輥18)的紗線行進方向上游側設置對紗線Y賦予撚的加撚裝置15，並在紗線行進方向上於高速喂紗輥與低速喂紗輥(第4喂紗輥20)之間設置有對紗線Y進行加熱的第2加熱裝置19。這種情況下，由於藉由第2加熱 裝置19加熱的紗線Y變成鬆弛狀態，因此在高速喂紗輥的紗線行進方向下游側紗線Y容易搖擺，對高速喂紗輥設置靜電去除機構50特別有效。 In addition, in the present embodiment, a twisting device 15 for imparting twist to the yarn Y is installed on the upstream side of the high-speed yarn feeding roller (third yarn feeding roller 18) in the yarn traveling direction, and the twisting device 15 is set at a high speed in the yarn traveling direction. A second heating device 19 for heating the yarn Y is provided between the yarn feeding roller and the low-speed yarn feeding roller (the fourth yarn feeding roller 20). In this case, due to the second heating The yarn Y heated by the device 19 becomes a relaxed state, and therefore the yarn Y tends to sway on the downstream side in the yarn traveling direction of the high-speed yarn feeding roller. It is particularly effective to provide the static electricity removing mechanism 50 to the high-speed yarn feeding roller.

並且，在本實施方式中，靜電去除機構50以不與上述旋轉體(第3喂紗輥18，特別是旋轉軸43)接觸的形態設置。在靜電去除機構50與旋轉體接觸的情況下，由於靜電去除機構50、旋轉體磨損，存在不能夠適當地除去靜電、或者零件更換頻率增大的風險。並且，由於靜電去除機構50與旋轉體接觸，存在反而增加靜電去除機構50與旋轉體之間產生的靜電量的風險。但是，在靜電去除機構50不與旋轉體接觸的情況下，能夠防止靜電去除機構50、旋轉體的磨損，能夠避免上述這樣的問題。 In addition, in the present embodiment, the static electricity removing mechanism 50 is provided in a form that does not contact the above-mentioned rotating body (the third yarn feeding roller 18, and the rotating shaft 43 in particular). When the static electricity removing mechanism 50 is in contact with the rotating body, there is a risk that the static electricity removing mechanism 50 and the rotating body are worn out, and the static electricity cannot be properly removed or the frequency of parts replacement increases. In addition, since the static electricity removing mechanism 50 is in contact with the rotating body, there is a risk of increasing the amount of static electricity generated between the static electricity removing mechanism 50 and the rotating body. However, when the static electricity removing mechanism 50 is not in contact with the rotating body, the static electricity removing mechanism 50 and the rotating body can be prevented from being worn out, and the above-mentioned problems can be avoided.

並且，在本實施方式中，前述旋轉體(第3喂紗輥18)構成為具有：旋轉軸43、和安裝在旋轉軸43上且使紗線Y與其外周面接觸的輥41，對旋轉軸43設置了靜電去除機構50。這樣，藉由對旋轉軸43設置靜電去除機構50，與對輥41設置的情況相比，能夠抑制靜電去除機構50朝向徑向的大型化，能夠成為緊緻的結構。 In addition, in this embodiment, the aforementioned rotating body (third yarn feeding roller 18) is configured to have a rotating shaft 43, and a roller 41 mounted on the rotating shaft 43 and contacting the outer peripheral surface of the yarn Y with the rotating shaft. 43 is provided with a static electricity removing mechanism 50. In this way, by providing the static electricity removing mechanism 50 to the rotating shaft 43, compared with the case of providing the roller 41, the static electricity removing mechanism 50 can be suppressed from being enlarged in the radial direction, and a compact structure can be achieved.

並且，在本實施方式中，靜電去除機構50構成為具有：被接地的支承構件51、和以沿著旋轉軸43的外周面的方式安裝在支承構件51上的靜電消除構件52。藉由以沿著旋轉軸43的外周面的方式設置靜電消除構件52，能夠確保寬闊的從旋轉軸43向靜電消除構件52放電 的區域，能夠更確實地將靜電除去。 In addition, in the present embodiment, the static electricity removing mechanism 50 is configured to include a support member 51 that is grounded, and a static electricity removing member 52 that is attached to the support member 51 so as to be along the outer peripheral surface of the rotating shaft 43. By disposing the static elimination member 52 along the outer peripheral surface of the rotating shaft 43, it is possible to ensure a wide discharge from the rotating shaft 43 to the static elimination member 52 In the area, the static electricity can be removed more reliably.

並且，在本實施方式中，由於靜電消除構件52沿著旋轉軸43的軸向設置，因此能夠抑制軸向上放電性能的偏差，能夠適當地進行放電。 In addition, in the present embodiment, since the static elimination member 52 is provided along the axial direction of the rotating shaft 43, it is possible to suppress variations in discharge performance in the axial direction, and discharge can be performed appropriately.

並且，本實施方式的靜電消除構件52中，由於在導電性纖維露出的多個部位發生放電，因此能夠提高靜電消除構件的靜電消除性能。 In addition, in the static elimination member 52 of the present embodiment, since discharge occurs at a plurality of locations where the conductive fibers are exposed, the static elimination performance of the static elimination member can be improved.

並且，在本實施方式中，設置了為了不讓靜電消除構件52露出而將其覆蓋的蓋構件60。若靜電消除構件52上附著了塵埃等，則向靜電消除構件52的放電變得不易發生，存在靜電消除性能降低的風險。但是，藉由像上述那樣設置蓋構件60，能夠抑制塵埃等向靜電消除構件52附著，能夠避免靜電消除性能的降低。 In addition, in the present embodiment, a cover member 60 that covers the static elimination member 52 so as not to expose the static elimination member 52 is provided. If dust or the like adheres to the static elimination member 52, discharge to the static elimination member 52 becomes less likely to occur, and there is a risk that the static elimination performance decreases. However, by providing the cover member 60 as described above, it is possible to prevent dust and the like from adhering to the static elimination member 52, and it is possible to avoid a decrease in static elimination performance.

並且，在加工尼龍製的紗線Y的情況下，由於與帶電部位的摩擦特別容易產生靜電。因此，本實施方式的假撚加工機1在對由尼龍製作的紗線Y進行加工的情況下，設置靜電去除機構50的效果變得更加顯著。 In addition, when the nylon yarn Y is processed, it is particularly easy to generate static electricity due to friction with the charged portion. Therefore, in the false twist processing machine 1 of the present embodiment, when processing the yarn Y made of nylon, the effect of providing the static electricity removing mechanism 50 becomes more remarkable.

(其他實施方式) (Other embodiments)

雖然以上說明了本發明的實施方式，但能夠應用本發明的形態並不局限於上述實施方式，像以下舉例說明的那樣，在不超出本發明主旨的範圍內能夠施加適當的變更。 Although the embodiment of the present invention has been described above, the form to which the present invention can be applied is not limited to the above-mentioned embodiment, and as illustrated below, appropriate changes can be made without departing from the scope of the present invention.

例如，上述實施方式中將本發明應用於假撚加工機1。但是，也可以將本發明應用於具有上述實施方 式以外的結構的假撚加工機、紡紗延伸裝置等之用於製造或加工由合成纖維構成的紗線的纖維機械。 For example, in the above-mentioned embodiment, the present invention is applied to the false twisting machine 1. However, the present invention can also be applied to a method having the above-mentioned embodiments Fabric machinery used for manufacturing or processing yarns made of synthetic fibers, such as false twisting machines and spinning stretching devices with structures other than the formula.

並且，如上述實施方式也提到的那樣，設置靜電去除機構50的部位並不局限於第3喂紗輥18。例如，在交織裝置17，為了適當地賦予交織而使紗線Y變成鬆弛狀態，因此受積累在配置於交織裝置17的紗線行進方向上游側的第2喂紗輥16上的靜電的影響，紗線Y的行進容易變得不穩定。因此，對第2喂紗輥16設置靜電去除機構50也是有效的。這種情況下，第2喂紗輥16相當於本發明的“高速喂紗輥”，第3喂紗輥18相當於本發明的“低速喂紗輥”。另外，第2喂紗輥16的基本結構與第3喂紗輥18同樣。 In addition, as also mentioned in the above-mentioned embodiment, the location where the static electricity removing mechanism 50 is provided is not limited to the third yarn feeding roller 18. For example, in the interlacing device 17, the yarn Y becomes slack in order to appropriately impart interlacing. Therefore, it is affected by the static electricity accumulated on the second yarn feeding roller 16 arranged on the upstream side of the yarn traveling direction of the interlacing device 17. The travel of the yarn Y tends to become unstable. Therefore, it is also effective to provide the static electricity removing mechanism 50 to the second yarn feeding roller 16. In this case, the second yarn feeding roller 16 corresponds to the "high-speed yarn feeding roller" of the present invention, and the third yarn feeding roller 18 is equivalent to the "low-speed yarn feeding roller" of the present invention. In addition, the basic structure of the second yarn supplying roller 16 is the same as that of the third yarn supplying roller 18.

並且，如果在摩擦盤式加撚裝置15中產生靜電，則加撚裝置15中紗線Y的行進變得不穩定，紗線Y不會通過預定的紗道，存在不能夠賦予適當的撚的風險。因此，對加撚裝置15設置靜電去除機構50也是有效的。 In addition, if static electricity is generated in the friction disc twisting device 15, the traveling of the yarn Y in the twisting device 15 becomes unstable, the yarn Y does not pass through a predetermined yarn path, and it is impossible to impart proper twist. risk. Therefore, it is also effective to provide the static electricity removing mechanism 50 to the twisting device 15.

除此以外，也可以在第1喂紗輥11、第4喂紗輥20、止撚導絲器12等適當的帶電部位設置靜電去除機構50。 In addition to this, the static electricity removing mechanism 50 may be provided in appropriate electrified parts such as the first yarn feeding roller 11, the fourth yarn feeding roller 20, and the twist prevention guide 12.

並且，靜電去除機構50的具體結構也並不局限於上述實施方式敘述的結構。例如，雖然在上述實施方式中對驅動輥41的旋轉軸43設置了靜電去除機構50，但也可以對驅動輥41設置。並且，也可以構成為使靜電去除機構50與帶電部位接觸。並且，也可以在帶電部位 附近配置靜電消除用的金屬針等，從帶電部位向金屬針等產生放電。並且，靜電消除構件52也可以是例如編入導電性纖維並束成繩帶狀的紗線。由於是束成繩帶狀的紗線，因此對於支承構件51的安裝變得容易。具體為，使該紗線成為環形並繫在支承構件51上，或者使用導電性黏著劑黏著到支承構件51，或者使用適當的金屬線等固定在支承構件51上，藉由這樣使靜電消除構件52對於支承構件51的安裝變得容易。 In addition, the specific structure of the static electricity removing mechanism 50 is not limited to the structure described in the above-mentioned embodiment. For example, although the static electricity removing mechanism 50 is provided to the rotating shaft 43 of the driving roller 41 in the above-described embodiment, it may be provided to the driving roller 41. In addition, it may be configured such that the static electricity removing mechanism 50 is brought into contact with the charged portion. And, it can also be used in live parts Metal needles for static elimination are placed nearby, and discharge is generated from the charged parts to the metal needles. In addition, the static elimination member 52 may be, for example, a yarn woven with conductive fibers and bundled into a string shape. Since the yarn is bundled in a rope shape, it is easy to attach the support member 51. Specifically, the yarn is looped and tied to the support member 51, or adhered to the support member 51 with a conductive adhesive, or fixed to the support member 51 with an appropriate metal wire, etc., so that the static elimination member The mounting of 52 to the supporting member 51 becomes easy.

並且，雖然在上述實施方式中加撚裝置15是採用摩擦盤式裝置，但也可以應用例如日本特開2010-65354號公報中揭示的那種帶式夾持加撚裝置。 In addition, although the twisting device 15 is a friction disc type device in the above-mentioned embodiment, for example, a belt-type clamping twisting device disclosed in Japanese Patent Application Laid-Open No. 2010-65354 may be applied.
