Description
本發明係有關於一種橡膠加強用織物編織用織機中所使用之織入邊形成裝置。The present invention relates to a weaving edge forming device used in a weaving machine for woven fabric for rubber reinforcement.
作為由無梭織機編織之織物之織邊組織之一，存在以下之織入邊，該織入邊是將已投入之緯線之端部向後續之緯線所投入之經線開口內折回，使該端部與後續之緯線一起折入至織物中而成之。作為形成該織入邊之裝置，已知有專利文獻1所公開之空氣噴射式之織入邊形成裝置。此外，將已投入之緯線之端部向後續之緯線所投入之經線開口內折回之動作稱為織入。再者，空氣噴射式之織入邊形成裝置也被稱為空氣打摺機(air tucker)。As one of the selvage structures of the fabric woven by the shuttleless loom, there is a woven edge which is folded back into the warp opening into which the subsequent weft is inserted, so that the woven edge is folded back. The end is folded into the fabric together with the subsequent weft. As an apparatus for forming the woven edge, an air jet type woven edge forming apparatus disclosed in Patent Document 1 is known. Further, the operation of folding back the end portion of the inserted weft thread into the warp opening into which the subsequent weft is inserted is referred to as weaving. Further, the air jet type weaving edge forming device is also referred to as an air tucker.
空氣噴射式之織入邊形成裝置以配置於經線列之兩側方之織入頭為主體，各個織入頭具有用以使緯線折回之織入噴嘴。而且，藉由從該織入噴嘴噴射出之噴射氣流，將已投入之緯線之兩端部向經線開口內折回，由此進行織入。The air jet type weaving edge forming device is mainly provided with a weaving head disposed on both sides of the warp row, and each of the weaving heads has a weaving nozzle for folding the weft. Then, the both ends of the inserted weft are folded back into the warp opening by the jet flow jetted from the weaving nozzle, thereby performing weaving.
然而，於無梭織機所編織之織物中，存在像用作加強橡膠材料之芯材之橡膠加強用織物(以下稱為“橡膠加強用織物”)那樣，包含緯線密度非常粗疏之編織部分(以下稱為“簾織部分”)之織物。作為橡膠加強用織物之一例，可列舉輪胎簾布織物。However, in the woven fabric woven by the shuttleless looms, there is a woven portion having a very fine weft density (hereinafter referred to as a "rubber reinforcing fabric") as a core material for reinforcing a rubber material (hereinafter, A fabric called a "curtain portion". An example of the rubber reinforcing fabric is a tire cord fabric.
對於橡膠加強用織物之簾織部分，從橡膠加強用織物之質量之觀點考慮，要求經織入之緯線之端部配合緯線之間隔(密度)而大幅地描繪出弧線，並成為沿著經打緯之後續之緯線之狀態(參照圖1)。For the curtain portion of the rubber reinforced fabric, from the viewpoint of the quality of the reinforced fabric for rubber reinforcement, it is required that the end portion of the woven weft thread is matched with the interval (density) of the weft to substantially draw an arc and become a warp. The state of the latitude after the latitude (see Figure 1).
參照圖7進行詳述，織口(即將投入之緯線之束縛點)54於從打緯時點至下一週期之打緯時點為止之期間內，向經線方向移動與緯線密度相當之量。於簾織之情況下，緯線密度(緯線之間隔)非常粗疏(例如1根/英吋)，與緯線密度大之普通編織相比，經線之進給速度非常快，換句話說，每一週期之移動量非常大，因此，織口54於一個週期內，從打緯位置45(也稱為打緯點，其指筘之打緯部(將緯線打靠至織口之部分)之最靠前位置。以下相同)向經線送出方向大幅移動。而且，因為經線之開口以織口54為起點而打開，所以隨著織口54之移動，經線開口之起點43b之位置也會成為向經線送出方向離開打緯位置45之狀態。Referring to Fig. 7, the weaving mouth (the binding point of the weft to be fed) 54 is moved to the warp direction by an amount corresponding to the weft density in the period from the beating time to the beating time of the next cycle. In the case of curtain weaving, the weft density (the spacing of the wefts) is very coarse (for example, 1/inch), and the warp feed speed is very fast compared to the ordinary weave with a large weft density, in other words, each The amount of movement of the cycle is very large, so the weaving port 54 is in the cycle from the beating position 45 (also called the beating point, which is the most part of the beating section (the part that hits the weft to the weaving mouth) The position in front is the same as the direction in which the warp is sent out. Further, since the opening of the warp is opened with the weaving opening 54 as the starting point, the position of the starting point 43b of the warp opening becomes a state of leaving the beating position 45 in the warp feeding direction as the weaving opening 54 moves.
如此，於簾織之情況下，因為先投入之緯線與對接下來投入之緯線進行打緯時之打緯位置45之間之間隔大，所以欲使已折回之緯線之端部42c之前端部成為沿著後續之緯線之狀態，緯線之端部42成為大幅地描繪出弧線之形狀較為理想。Thus, in the case of the curtain weaving, since the interval between the weft inserted first and the beating position 45 when wefting the next weft is large, the end portion of the end portion 42c of the folded weft is to be Along the state of the subsequent weft, it is preferable that the end portion 42 of the weft is a shape in which the arc is largely drawn.
然而，對於先前之使用空氣噴射式之織入邊形成裝置來形成織入邊之織機而言，於編織橡膠加強用織物之過程中，難以穩定且漂亮地形成如圖1所示之織入邊。其理由如下上述。However, in the case of the prior art loom which uses the air jet type weaving edge forming means to form the weaving edge, it is difficult to stably and beautifully form the weaving side as shown in Fig. 1 during the weaving of the rubber reinforcing fabric. . The reason is as follows.
1)如圖7所示，對於先前之上述織機而言，如緯線之端部42b所示，於多數情況下，不會成為折回之緯線之端部大幅地描繪出弧線之狀態，而是成為以下狀態，即，從與織入之緯線相連之部分起立即彎曲，並呈銳角地折回。1) As shown in Fig. 7, in the above-described weaving machine, as shown in the end portion 42b of the weft, in many cases, the end portion of the weft which does not become the weft is largely drawn in the state of the arc, but becomes The following state, that is, immediately bent from the portion connected to the weft of the weave, is folded back at an acute angle.
詳細而言，當藉由空氣噴射將緯線之端部42c向經線開口內折回時，緯線之端部42c強烈地傾向於以其束縛點(經線開口之起點43b)為支點而發生彎曲。因此，緯線之端部42c不會成為大幅地描繪出弧線之狀態，而是於經線開口之起點43b處立即折回(參照圖示之緯線之端部42b)，從而無法獲得所需形狀之織入邊。In detail, when the end portion 42c of the weft is folded back into the warp opening by air jet, the end portion 42c of the weft is strongly inclined to be bent with its binding point (starting point 43b of the warp opening) as a fulcrum. Therefore, the end portion 42c of the weft does not become a state in which the arc is largely drawn, but is immediately folded back at the starting point 43b of the warp opening (refer to the end portion 42b of the weft shown in the drawing), so that the desired shape cannot be obtained. Enter the edge.
2)如上所述，於簾織之情況下，因為經線之進給速度快，所以於緯線打緯後之經線開口發生反轉之過程中，與織入頭31相連之緯線之端部42c成為以下狀態，即，於經線方向上之離開經線開口之起點43b之位置，與經線列之最外側之經線交叉。即，對於普通編織而言，每一個週期之織口之移動量極小，因此，緯線之端部大致位於開口之起點附近，但於簾織之情況下，因為織口之移動量大，所以直至經線開口反轉至束縛緯線之程度為止，於經線列之最外側之經線之位置，緯線之端部42c成為通過離開開口之起點43b之位置而與織入頭相連之狀態。2) As described above, in the case of the curtain weave, since the feed speed of the warp is fast, the end of the weft thread connected to the weaving head 31 is reversed during the inversion of the warp opening after the weft beating. 42c is in a state in which the position of the starting point 43b of the warp opening in the warp direction intersects with the warp of the outermost side of the warp line. That is, for ordinary knitting, the amount of movement of the weaving mouth per cycle is extremely small, and therefore, the end portion of the weft is substantially located near the starting point of the opening, but in the case of the curtain, since the amount of movement of the weaving port is large, it is up to The warp opening is reversed to the extent that the weft is restrained, and the end portion 42c of the weft is at a position separated from the weaving head by a position away from the starting point 43b of the opening at the position of the outermost warp of the warp row.
於此情況下，如圖7所示，隨著反轉後之經線43之開口運動，與織入頭31相連之緯線之端部42c由最外側之經線提向上方或按向下方而成為繃緊之狀態，該部分之張力上升，並且成為從織入頭31側抽出緯線之端部42c之狀態。而且，此成為阻礙形成所需之織入邊形狀之要因。In this case, as shown in Fig. 7, with the opening movement of the warp yarn 43 after the reverse rotation, the end portion 42c of the weft thread connected to the weaving head 31 is lifted upward or downward by the outermost warp thread. In a state of being stretched, the tension of the portion is raised, and the end portion 42c of the weft is extracted from the side of the weaving head 31. Moreover, this is a factor that hinders the formation of the desired woven edge shape.
此外，作為包括與橡膠加強用織物之簾織部分相對應之織入邊形成裝置之橡膠加強用織物編織用之織機，存在專利文獻2所公開之先前技術。於專利文獻2之技術中，設置從織物側向筘側噴射空氣之噴嘴，藉由來自該噴嘴之噴射空氣將經織入之緯線之端部推回筘側，從而穩定地形成簾織部分所需之上述織入邊。Further, as a weaving machine for woven fabric for rubber reinforcement including a woven edge forming device corresponding to a woven fabric portion of a reinforced fabric for rubber reinforcement, there is a prior art disclosed in Patent Document 2. In the technique of Patent Document 2, a nozzle for ejecting air from the side of the fabric to the crotch side is provided, and the end portion of the weft-inserted weft is pushed back to the crotch side by the jet air from the nozzle, thereby stably forming the curtain portion. The above weaving edge is required.
然而，對於該先前技術而言，必須設置如上所述之噴嘴以及用以供給空氣之機構(流體供應管、電磁開閉閥等)，並且還需要用以對該噴射進行控制之裝置，因此，用以形成織入邊之裝置結構變得複雜，並且裝置成本變高。而且，因為依然會產生由最外側之經線引起之緯線端部之位移，所以無法穩定地形成所需之織入邊形狀。However, with this prior art, it is necessary to provide a nozzle as described above and a mechanism for supplying air (fluid supply pipe, electromagnetic opening and closing valve, etc.), and a device for controlling the injection is also required, and therefore, The structure of the device to form the woven edge becomes complicated, and the device cost becomes high. Moreover, since the displacement of the end portion of the weft caused by the outermost warp is still generated, the desired woven edge shape cannot be stably formed.

因此，本發明之課題在於鑒於上述先前技術之問題而提供一種織入邊形成裝置，對於橡膠加強用織物之簾織部分，該織入邊形成裝置能夠以簡單且廉價之結構來穩定地形成如上所述之織入邊。Accordingly, an object of the present invention is to provide a woven edge forming device which can stably form the above-described woven edge forming device with a simple and inexpensive structure in view of the above problems of the prior art. The woven edge is as described.
為了解決上述問題，本發明以如下方式構成織入邊形成裝置。In order to solve the above problems, the present invention constitutes a woven edge forming device in the following manner.
即，本發明之織入邊形成裝置被用於橡膠加強用織物編織用織機中，該橡膠加強用織物編織用織機是用以編織包括簾織部分1a之橡膠加強用織物1之織機，其包括具有1個以上之織入噴嘴32之空氣噴射式之織入邊形成裝置30，該1個以上之織入噴嘴32配置於經線列之側方以對已投入之緯線之端部2a進行織入。而且，織入邊形成裝置30之技術要點在於：包括限制裝置20，該限制裝置20於經線方向上之至少筘之最靠前位置5附近，且於包括織寬方向上之最外側之經線3a之經線列之一部分區域中，限制經線3之開口。In other words, the woven edge forming apparatus of the present invention is used in a woven fabric for woven fabric for woven fabric, which is a weaving machine for knitting a rubber reinforced fabric 1 including a woven portion 1a, which includes An air jet type weaving edge forming device 30 having one or more weaving nozzles 32, and the one or more weaving nozzles 32 are disposed on the side of the warp row to woven the end portion 2a of the inserted weft thread In. Further, the technical point of the weaving edge forming device 30 is to include a restricting device 20 which is adjacent to at least the most forward position 5 of the warp direction and which includes the outermost side in the weaving width direction. In a portion of the warp row of line 3a, the opening of warp 3 is restricted.
此外，所謂“筘之最靠前位置”，如上所述，一般係指被稱為“打緯位置(打緯點)”之位置，該位置為筘之打緯部(與緯線接觸地將緯線打靠至織口之部分)之最靠前位置。參照表示本發明之一個實施例之圖2進行說明，所謂筘之最靠前位置5，係指筘4(變形筘羽6)之打緯部6b之最靠前位置，即筘4前進至虛線位置為止時之打緯部6b之位置。Further, the term "the most forward position of the cymbal", as described above, generally refers to a position called "beating position (beatning point)", which is the beating portion of the cymbal (the weft is in contact with the weft) The most forward position of the part of the weaving mouth. Referring to Fig. 2 showing an embodiment of the present invention, the most front position 5 of the 筘 is the most forward position of the beating portion 6b of the 筘 4 (deformation 筘 feather 6), that is, 筘4 advances to the dotted line. The position of the beating portion 6b at the time of the position.
再者，所謂“限制經線之開口”，係指於上述一部分區域中，限制經線列由於開口運動而上下地分開，藉此，使上述區域中之經線開口之起點3b之位置總是維持於筘之最靠前位置5附近，防止隨著由經線之進給所引起之織口之移動，使經線開口之起點3b向經線送出方向離開筘之最靠前位置。Further, the term "restricting the opening of the warp" means that the warp beam is restricted from being vertically divided by the opening movement in the partial region, whereby the position of the starting point 3b of the warp opening in the region is always It is maintained near the most forward position 5 of the crucible to prevent the movement of the weaving opening caused by the feeding of the warp, so that the starting point 3b of the warp opening is directed away from the front position of the warp.
此外，所謂“筘之最靠前位置之附近(位置)”，係指向織口側離開不與筘接觸之筘之最靠前位置5之位置，該位置是打緯時之上一次投入之緯線之位置與筘之最靠前位置5之間之位置。但是，更較佳之位置是儘可能地接近筘之最靠前位置之位置，即，於限制裝置20與筘不發生接觸之情況下，儘可能地接近筘之最靠前位置5之位置。In addition, the so-called "near position (position) of the top position of the cymbal is directed to the position of the most forward position 5 of the cymbal side that is not in contact with the cymbal, which is the latitude of the upper input when the weft is applied. The position between the position and the most forward position 5 of the cymbal. However, the more preferred position is as close as possible to the position of the most forward position of the crucible, i.e., as close as possible to the position of the most forward position 5 of the crucible in the event that the restriction device 20 does not come into contact with the crucible.
再者，所謂“至少筘之最靠前位置之附近”，係指不僅包含限制裝置20僅存在於筘之最靠前位置5附近以限制經線3之開口之情況，而且還包含以下情況，即，限制裝置20存在於包括筘之最靠前位置5附近之經線方向之特定範圍內，於該範圍中限制經線3之開口。例如，於圖1、圖2所示之實施例中，限制裝置20之限制經線開口之部分(上構件21、下構件22)於沿著經線方向延伸之範圍(大致相當於緯線之間隔)內，限制經線3之開口。In addition, the phrase "at least the vicinity of the most forward position" means not only the restriction device 20 but only the vicinity of the most front position 5 of the crucible to restrict the opening of the warp 3, and the following cases are also included. That is, the restriction device 20 exists in a specific range including the warp direction near the most forward position 5 of the crucible, and the opening of the warp 3 is restricted in the range. For example, in the embodiment shown in FIGS. 1 and 2, the portion of the restriction device 20 that restricts the warp opening (the upper member 21 and the lower member 22) extends in the warp direction (substantially corresponds to the interval of the weft). Within the limit, the opening of the warp 3 is restricted.
即，於本發明中，亦可設為以下結構：上述限制裝置20包括構件21、22，該構件21、22設置於織入時之上一次投入之緯線2b與上述筘之最靠前位置5之間，並於橡膠加強用織物1之厚度方向上隔著上述經線列而相向。此外，限制裝置20僅存在於筘之最靠前位置5附近之例子雖然未圖示，然而可列舉以下之例子，即，於筘之最靠前位置5附近，由於織寬方向上延伸之一對棒狀構件隔著織物來限制經線之開口。That is, in the present invention, the restriction device 20 may include the members 21 and 22 which are provided at the uppermost position 2b of the upper input and the front position 5 of the above-mentioned cymbal at the time of weaving. In the thickness direction of the rubber reinforcing fabric 1, they are opposed to each other across the warp line. Further, although the example in which the restriction device 20 is present only in the vicinity of the most forward position 5 of the crucible is not shown, an example in which the vicinity of the most forward position 5 of the crucible is extended in the width direction of the crucible is exemplified. The opening of the warp is restricted to the rod member by a fabric.
亦可設為以下結構：上述織機是具有包括變形筘羽6之筘4之空氣噴射式織機，該變形筘羽6具有用以形成緯線引導槽8之凹部6a，上述筘4之織寬方向上之端部之筘羽由平筘羽7形成。It is also possible to adopt a configuration in which the above-mentioned loom is an air-jet loom having a crucible 4 including a deformed feather 6 having a concave portion 6a for forming a weft guiding groove 8, in the weaving width direction of the above-mentioned crucible 4 The feather of the end is formed by the flat feathers 7.
此外，亦可設為以下結構：上述筘4中之由平筘羽7形成之部分被設定成於織寬方向上，與筘4之端部相距10mm以下。Further, a configuration may be adopted in which the portion formed by the flat feathers 7 in the above-mentioned crucible 4 is set to be in the weaving width direction and is spaced apart from the end portion of the crucible 4 by 10 mm or less.
藉由限制裝置20限制包括織寬方向上之最外側之經線3a之經線3之開口，因此，可使經線開口之起點3b持續地位於筘之最靠前位置5附近。使用圖2進行說明，即使織口14隨著織布之捲取向送出側之相反側移動，因為於限制裝置20之存在範圍內，經線3之開口受到限制，所以可使經線開口之起點3b持續地位於筘之最靠前位置5附近。結果成為以下狀態：即使緯線之端部2a於經線開口之起點3b折回，其也會於離開織口14之位置折回，因此，成為大幅地描繪出弧線之狀態。藉此，織入邊成為所需之形狀。The opening of the warp thread 3 including the warp beam 3a of the outermost side in the weaving width direction is restricted by the restricting means 20, so that the starting point 3b of the warp opening can be continuously positioned near the most forward position 5 of the weir. As will be described with reference to Fig. 2, even if the weaving opening 14 moves along the opposite side of the roll-oriented feeding side of the woven fabric, since the opening of the warp thread 3 is restricted within the range of the restriction device 20, the starting point of the warp opening can be made. 3b is continuously located near the top 5 of the 筘. As a result, even if the end portion 2a of the weft is folded back at the starting point 3b of the warp opening, it is folded back at a position away from the weaving port 14, and therefore, the state of the arc is largely drawn. Thereby, the woven edge becomes the desired shape.
再者，藉由限制經線3之開口，與織入頭31相連之緯線之端部2a於打緯後之經線3開口之過程中，不會被經線列之最外側之經線3上提(或下壓)，因此，可防止由此引起之於形成織入邊方面之阻礙，從而可穩定地形成所需之織入邊。Furthermore, by restricting the opening of the warp thread 3, the end portion 2a of the weft thread connected to the weaving head 31 is not opened by the outermost warp thread 3 of the warp line during the opening of the warp thread 3 after the beating. The lifting (or pressing) is performed, so that the hindrance caused by the formation of the woven edge can be prevented, so that the desired woven edge can be stably formed.
藉由將包括變形筘羽之筘4之端部之筘羽設為平筘羽7，根據以下之理由，可容易地設定限制裝置20於經線方向上之位置。By setting the feathers including the end portions of the ridges 4 of the deformed feathers to the flat feathers 7, the position of the restriction device 20 in the warp direction can be easily set for the following reasons.
使用圖2進行說明，為了形成所需之織入邊，較佳為儘可能地使經線開口之起點3b接近筘之最靠前位置5。因此，較佳為儘可能接近筘之最靠前位置5地設置限制裝置20。2, in order to form the desired weaving edge, it is preferable to make the starting point 3b of the warp opening as close as possible to the most front position 5 of the weir. Therefore, it is preferable to provide the restriction device 20 as close as possible to the most forward position 5 of the crucible.
然而，於筘羽完全由變形筘羽6形成之筘之情況下，於使筘位於最靠前位置之狀態(圖2之虛線之狀態)下，限制裝置20之限制經線開口之部分(以下也稱為“限制部分”)成為進入至筘之凹部6a內之狀態，因此，無法目視凹部6a之底部之打緯部6b與限制部分之間之位置關係。因此，難以把握筘之最靠前位置5與限制裝置20之限制部分之間之距離。However, in the case where the 筘 feather is completely formed by the deformed 筘 feather 6, the portion of the restriction device 20 that restricts the warp opening (hereinafter, the state in which the 筘 is located at the most forward position (the state of the broken line in Fig. 2) The "restricted portion" is also in a state of entering into the recessed portion 6a of the crucible. Therefore, the positional relationship between the beating portion 6b at the bottom of the recessed portion 6a and the restricting portion cannot be visually observed. Therefore, it is difficult to grasp the distance between the most forward position 5 of the crucible and the restricted portion of the restriction device 20.
因此，若將筘4之端部之筘羽設為平筘羽7(參照圖6)，則可不受筘羽遮擋地目視筘之最靠前位置5即打緯點與限制裝置20之限制部分之間之位置關係，從而可容易地將限制裝置20之限制部分設定成儘可能接近打緯點之狀態。但是，將筘4之端部設為平筘羽7之目的，僅僅是為了容易調整限制裝置20於經線方向上之位置，所以於本發明中並非為必需之結構。因此，筘羽亦可全部為上述變形筘羽6。Therefore, if the feather of the end of the crucible 4 is set to the flat feather 7 (refer to FIG. 6), the most forward position 5 of the visual obstruction can be viewed without being blocked by the feather, that is, the restriction portion of the beating point and the restriction device 20. The positional relationship between them makes it possible to easily set the restricted portion of the restriction device 20 as close as possible to the state of the beating point. However, the purpose of setting the end portion of the crucible 4 to the flat feathers 7 is merely to adjust the position of the restriction device 20 in the warp direction, and therefore is not essential in the present invention. Therefore, the feathers can also be all of the above-described deformed feathers 6.
使筘4之由平筘羽7形成之部分與筘4之端部相距10mm以下，由此，可獲得上述效果而不會阻礙緯線之穿行。參照圖6進行說明，於空氣噴射式織機中，由變形筘羽6之凹部6a形成之緯線引導槽8原本用以引導緯線之穿行，若不存在該緯線引導槽8，則其功能會受影響。換句話說，若平筘羽7之所設範圍過大，則其成為阻礙緯線之穿行之要因。因此，發明人進行認真研究後，結果已知：若平筘羽7之所設範圍與筘4之端部相距10mm以下，則於設想之編織條件之範圍內，可實現大致良好之投緯。由此，藉由將平筘羽7之所設範圍設定為與筘4之端部相距10mm以下，可獲得上述效果而不會對緯線之穿行造成不良影響。The portion of the crucible 4 formed by the flat feathers 7 is spaced apart from the end portion of the crucible 4 by 10 mm or less, whereby the above effects can be obtained without hindering the passage of the weft. Referring to Fig. 6, in the air jet loom, the weft guide groove 8 formed by the concave portion 6a of the deformed feather 6 is originally used to guide the passage of the weft, and if the weft guide groove 8 is not present, its function is affected. . In other words, if the range of the flat feathers 7 is too large, it becomes a factor that hinders the passage of the weft. Therefore, the inventors have earnestly studied and found that if the range of the flat feathers 7 is 10 mm or less from the end of the crucible 4, substantially good weft insertion can be achieved within the range of the envisaged knitting conditions. Thus, by setting the range of the flat feathers 7 to be 10 mm or less from the end of the crucible 4, the above effects can be obtained without adversely affecting the passage of the weft.
參照圖1～圖6說明本發明之織入邊形成裝置之一個實施例。圖1～圖6所示之例子係將本發明應用於用以編織橡膠加強用織物1之一即輪胎簾布織物之無梭織機之例子。An embodiment of the woven edge forming apparatus of the present invention will be described with reference to Figs. 1 to 6 . The example shown in Figs. 1 to 6 is an example in which the present invention is applied to a shuttleless loom for weaving a tire cord fabric which is one of the rubber reinforcing fabrics 1.
所謂輪胎簾布織物，係指用以製造作為橡膠輪胎骨骼之胎體層之橡膠加強用織物，如圖1所示，其包括緯線密度非常粗疏之簾織部分1a、和緯線密度比簾織部分密集之平織部分1b這兩個緯線密度彼此大不相同之編織部分。將橡膠材料塗佈至輪胎簾布織物1之簾織部分1a，藉此製造胎體層。The term "tire cord fabric" refers to a rubber reinforcing fabric for manufacturing a carcass layer as a skeleton of a rubber tire. As shown in FIG. 1, it includes a curtain portion 1a having a very fine weft density, and a weft density is denser than that of the curtain portion. The weave portion 1b is a woven portion in which the two weft densities are different from each other. A rubber material is applied to the curtain portion 1a of the tire cord fabric 1, whereby a carcass layer is produced.
圖1～圖6所示之織入邊形成裝置30是空氣噴射式之織入邊形成裝置，其於經線列之給線側之側方及給線側相反側之側方，設置有具有多個織入噴嘴32之織入頭31、和作為限制裝置20之上構件21及下構件22。此外，設置於給線側之織入頭31及限制裝置20、和設置於給線側相反側之織入頭及限制裝置呈左右對稱，且基本構造相同，因此，於以下之說明中，僅說明給線側之織入頭31及限制裝置20，省略給線側相反側之織入頭及限制裝置之說明及圖示。The weaving edge forming device 30 shown in Figs. 1 to 6 is an air jet type weaving edge forming device which is provided on the side of the line side of the warp line and the side opposite to the feed line side. A plurality of weaving heads 31 that are woven into the nozzles 32, and a member 21 and a lower member 22 as the upper limit of the restricting means 20. Further, the weaving head 31 and the restricting device 20 provided on the wire feeding side and the weaving head and the restricting device provided on the opposite side to the wire feeding side are bilaterally symmetrical and have the same basic structure. Therefore, in the following description, only The knitting head 31 and the restricting device 20 on the line side will be described, and the description and illustration of the weaving head and the restricting device on the opposite side to the line side will be omitted.
如圖1以及圖2所示，織入頭31為塊狀之構件，其配置於與經線列之經線開口相鄰之位置。織入頭31藉由安裝孔33而固定於未圖示之織機之邊撐支架等。於織入頭31之經線列之相反側設置有切斷緯線2之切斷器15。此外，圖1表示筘4對緯線2進行打緯後之狀態，經打緯之緯線2依靠於筘之最靠前位置5，藉由切斷器15使該緯線2與投緯噴嘴16內之緯線斷開。As shown in FIGS. 1 and 2, the weaving head 31 is a block-shaped member which is disposed adjacent to the warp opening of the warp row. The weaving head 31 is fixed to a temple bracket or the like of a loom (not shown) by a mounting hole 33. A cutter 15 for cutting the weft 2 is provided on the opposite side of the warp row of the weaving head 31. Further, Fig. 1 shows a state in which the weft 4 is subjected to beating after the weft 2, and the warp weft 2 is dependent on the most forward position 5 of the weir, and the weft 2 and the weft nozzle 16 are made by the cutter 15. The weft is broken.
於織入頭31中形成有接納經打緯之緯線之端部2a之狹縫34。狹縫34於經線之送出側(以下也僅稱為“送出側”)、經線列側以及切斷器15側這三側形成開口。而且，對織入頭31進行配置，使得當從送出側觀察時，狹縫34之底面34a位於織口14之正前。於織入頭31中之與比狹縫34靠送出側之狹縫34相連之部分，形成有上下地張開之引導面34b，使緯線之端部2a容易進入狹縫34。A slit 34 for receiving the end portion 2a of the beveled weft is formed in the weaving head 31. The slit 34 forms an opening on the three sides of the warp sending side (hereinafter also referred to as "sending side"), the warp row side, and the cutter 15 side. Further, the weaving head 31 is disposed such that the bottom surface 34a of the slit 34 is located directly in front of the weaving opening 14 when viewed from the feeding side. A portion of the weaving head 31 that is continuous with the slit 34 on the delivery side of the slit 34 is formed with a guide surface 34b that is vertically opened, so that the end portion 2a of the weft is easily inserted into the slit 34.
再者，織入頭31包括：緯線端把持噴嘴35，其將進入至狹縫34之緯線之端部2a暫時系留於狹縫34內；緯線釋放噴嘴36，其從狹縫34內噴出所系留之緯線之端部2a；以及織入噴嘴32，其將從狹縫34內噴出之緯線之端部2a噴入至經線開口內並使該端部2a呈環狀地折回。Further, the weaving head 31 includes a weft end gripping nozzle 35 that temporarily suspends the end portion 2a of the weft thread entering the slit 34 in the slit 34; the weft releasing nozzle 36 is ejected from the slit 34. The end portion 2a of the weft line is tied, and the weaving nozzle 32 is sprayed into the warp opening from the end portion 2a of the weft thread ejected from the slit 34, and the end portion 2a is folded back in an annular shape.
此外，織入噴嘴32包括於編織簾織部分1a時進行噴射動作之第一織入噴嘴32a、和於編織平織部分1b時進行噴射動作之第二織入噴嘴32b。Further, the woven nozzle 32 includes a first woven nozzle 32a that performs an ejector operation when the woven fabric portion 1a is woven, and a second woven nozzle 32b that performs an ejection operation when the plain woven portion 1b is woven.
關於編織簾織部分1a時進行噴射動作之第一織入噴嘴32a，於織入頭31之織物側之側面上，隔著狹縫34而上下各配設有兩個(共計四個)該第一織入噴嘴32a，從而形成織入噴嘴32a群。同樣地，關於編織平織部分1b時進行噴射動作之第二織入噴嘴32b，於比織入噴嘴32a靠送出側相反側處形成有織入噴嘴32b群。此外，本發明以編織簾織部分1a時之織入為對象，因此，於以下之說明中，說明藉由第一織入噴嘴32a進行織入。The first weaving nozzle 32a that performs the ejecting operation when the woven fabric portion 1a is woven is provided on the side of the fabric side of the woven head 31, and two (four in total) are disposed above and below the slit 34. A lance into the nozzle 32a forms a group of woven nozzles 32a. Similarly, the second weaving nozzle 32b that performs the ejecting operation when the plain weave portion 1b is knitted has a group of weaving nozzles 32b formed on the side opposite to the feeding side of the weaving nozzle 32a. Further, the present invention is directed to the weaving when the curtain portion 1a is woven, and therefore, in the following description, weaving is performed by the first weaving nozzle 32a.
作為本發明之特徵部分之限制裝置20於圖示之例子中，構成為隔著織物1使剖面呈L字形之上構件21及下構件22於上下方向上對稱地相向。以下，詳細地說明限制裝置20，但僅說明上下對稱之上構件21和下構件22中之上構件21，省略與下構件22相關之說明。In the illustrated example, the restriction device 20 which is a characteristic part of the present invention is configured such that the member 21 and the lower member 22 having a cross section in the L shape are symmetrically opposed to each other in the vertical direction via the woven fabric 1. Hereinafter, the restriction device 20 will be described in detail, but only the upper member 21 and the upper member 21 of the lower member 22 will be described, and the description relating to the lower member 22 will be omitted.
構成上構件21之部分中，於經線方向上延伸之部分作為限制經線3之開口之限制部21a而發揮作用，於上下方向上延伸之部分作為安裝部21b而發揮作用。Among the portions constituting the upper member 21, a portion extending in the warp direction functions as a regulating portion 21a that restricts the opening of the warp wire 3, and a portion extending in the vertical direction functions as the attaching portion 21b.
限制部21a於經線方向上，於織入開始時之上一次投入之緯線2b之存在位置(圖1之緯線2b)與筘之最靠前位置(打緯點)5之間延伸，該限制部21a具有大致與緯線間隔相同之經線方向之長度。而且，限制部21a配置成以不使限制部21a之筘側之端緣(前緣)干擾最靠前時之筘4之程度，儘可能地接近最靠前位置(打緯點)5。The restricting portion 21a extends in the warp direction between the existing position of the weft 2b (the weft 2b in FIG. 1) and the most forward position (the beating point) 5 of the weir at the start of weaving. The portion 21a has a length in the warp direction which is substantially the same as the weft interval. Further, the restricting portion 21a is disposed so as to be as close as possible to the most forward position (the beating point) 5 so as not to interfere with the edge (the leading edge) of the crotch side of the restricting portion 21a.
再者，限制部21a於織寬方向上，於包含經線列之最外側之經線3a之範圍內，向經線列內側延伸。此外，於圖示之例子中，限制部21a所延伸之織寬方向之範圍與編織端相距約10mm。Further, the restricting portion 21a extends inward in the weaving width direction to the inner side of the warp row in the range of the warp line 3a including the outermost side of the warp row. Further, in the illustrated example, the range in the width direction in which the restricting portion 21a extends is about 10 mm from the knitting end.
上構件21及下構件22藉由安裝部21b、22b而安裝於織機之固定部分，例如固定於未圖示之邊撐裝置之邊撐引導件等。The upper member 21 and the lower member 22 are attached to a fixed portion of the loom by the attachment portions 21b and 22b, for example, a temple guide that is fixed to a temple device (not shown).
接下來，參照圖3～圖5說明對緯線之端部2a進行織入之情況。此外，為了便於說明，於各圖(b)中省略了織入頭31之細部。Next, the case where the end portion 2a of the weft is woven is described with reference to Figs. 3 to 5 . Further, for convenience of explanation, the details of the weaving head 31 are omitted in each drawing (b).
圖3表示以下狀態，即，由筘4將緯線2打緯至最靠前位置(打緯點)5，且緯線之端部2a被織入頭31之狹縫34系留。此外，於圖3(b)中，緯線之端部2a表示為連結點A與點B之想像線。再者，雖然由實線表示經線3，但實際之經線具有一定程度之粗度。Fig. 3 shows a state in which the weft 2 is beaten by the weir 4 to the most forward position (the beating point) 5, and the end portion 2a of the weft is tied by the slit 34 of the weaving head 31. Further, in Fig. 3(b), the end portion 2a of the weft is shown as an imaginary line connecting the point A and the point B. Further, although the warp 3 is indicated by a solid line, the actual warp has a certain degree of thickness.
藉由緯線端把持噴嘴35及與緯線端把持噴嘴35相向地形成之緯線把持孔38來將緯線之端部2a系留於狹縫34內。即，於對已投入之緯線2進行打緯之後，若藉由切斷器15使該緯線2和與投緯噴嘴16相連之緯線斷開，則藉由從緯線端把持噴嘴35噴射出空氣，緯線之端部2a之前端部分被噴入至緯線把持孔38中，並藉由該噴射空氣之作用而保持於緯線把持孔38內。The end portion 2a of the weft is retained in the slit 34 by the weft end holding nozzle 35 and the weft holding hole 38 formed to face the weft end holding nozzle 35. That is, after the weft insertion 2 has been performed, if the weft 2 is disconnected from the weft thread connected to the weft nozzle 16 by the cutter 15, the air is ejected from the weft end holding nozzle 35, The front end portion of the end portion 2a of the weft is sprayed into the weft holding hole 38, and is held in the weft holding hole 38 by the action of the jet air.
圖4表示以下狀態，即，筘4從圖3之狀態向最靠後位置後退，經線3上下反轉，且織物1向進給方向前進。從打緯起經過規定之期間之後，緯線端把持噴嘴35停止空氣噴射，並且緯線釋放噴嘴36開始空氣噴射，藉由緯線釋放噴嘴36之噴射流，從緯線端把持孔38(參照圖2)中抽出緯線之端部2a，從狹縫34內噴出該緯線之端部2a。然後，第一織入噴嘴32a群開始空氣噴射，藉由第一織入噴嘴32a群之噴射流，將緯線之端部2a噴入至經線開口內，使該緯線之端部2a呈環狀地折回。Fig. 4 shows a state in which the crucible 4 is retracted from the state of Fig. 3 to the most rearward position, the warp 3 is reversed up and down, and the fabric 1 is advanced in the feeding direction. After a predetermined period of time from the beating, the weft end holding nozzle 35 stops the air jet, and the weft releasing nozzle 36 starts the air jet, and the jet of the weft releasing nozzle 36 is held from the weft end holding hole 38 (refer to FIG. 2). The end portion 2a of the weft is extracted, and the end portion 2a of the weft is ejected from the slit 34. Then, the first weaving nozzle 32a group starts air injection, and the end portion 2a of the weft is injected into the warp opening by the jet of the first weaving nozzle 32a, so that the end portion 2a of the weft is annular. The ground is folded back.
圖5表示以下狀態，即，緯線之端部2a折回，且筘4從最靠後位置起前進。此外，於圖5(b)中，從點B起省略了之前之緯線之端部2a之圖示。已折回之緯線之端部2a與後續之緯線一起經打緯，並與後續之緯線一起折入至織物1，從而織入結束。Fig. 5 shows a state in which the end portion 2a of the weft is folded back and the crucible 4 is advanced from the most rearward position. Further, in Fig. 5(b), the illustration of the end portion 2a of the previous weft is omitted from the point B. The end portion 2a of the folded-back weft is beaten together with the subsequent weft, and is folded into the fabric 1 together with the subsequent weft, so that the weaving ends.
如圖3～圖5所示，隨著織物1之進給，緯線之端部2a大幅地描繪出弧線。即，緯線之端部2a並非從與織入之緯線2相連之部分呈銳角地彎曲，而是由最外側之若干根經線從內側經線之位置(點A)開始彎折並緩緩地描繪出弧線，同時彎曲。如此，根據以下之理由，緯線2之端部2a成為描繪出弧線之狀態。As shown in FIGS. 3 to 5, as the fabric 1 is fed, the end portion 2a of the weft is largely drawn with an arc. That is, the end portion 2a of the weft is not bent at an acute angle from the portion connected to the weft thread 2, but is bent from the position of the inner warp (point A) by the outermost plurality of warps and slowly Depicts the arc while bending. As described above, the end portion 2a of the weft 2 is in a state in which an arc is drawn for the following reason.
對於經線列而言，因為藉由限制裝置20限制開口，所以即使織口14隨著織物1之進給而移動，經線開口之起點3b也總是維持於筘之最靠前位置5附近。而且，當進行織入時，限制裝置20中之限制部21之前緣位於與剛剛投入之緯線2之位置相距約緯線間隔之一半多之位置，於限制裝置20之存在範圍內，經線開口之起點3b被限制於該位置。因此，即使緯線之端部2a於經線開口之起點3b處折回，因為該折回位置(向投緯方向將朝向予以反轉之位置)離開織入之緯線2之位置，所以不會成為於與織入之緯線2相連之部分呈銳角地彎曲之狀態。For the warp row, since the opening is restricted by the restricting means 20, even if the weaving opening 14 moves with the feeding of the fabric 1, the starting point 3b of the warp opening is always maintained near the frontmost position 5 of the weir. . Moreover, when the weaving is performed, the leading edge of the restricting portion 21 in the restricting device 20 is located at a position which is more than one-half of the distance from the position of the weft 2 just input, and is within the existence range of the restricting device 20, and the warp opening is The starting point 3b is limited to this position. Therefore, even if the end portion 2a of the weft is folded back at the starting point 3b of the warp opening, since the folded position (the position in which the direction of the weft insertion is reversed) is away from the position of the weft 2 weaved, it does not become The portion of the woven weft 2 is bent at an acute angle.
再者，緯線之端部2a於打緯後之短時間(例如，直至筘到達最靠後位置為止之時間)內，緯線之端部2a之前端部分由織入頭31之緯線把持孔38所保持，因此，隨著織口之移動，緯線之端部2a成為向織口側相反側繃緊之狀態，與緯線2之其他部分相比，越是位於經線列外側之部分，則越向織口側相反側移動。從該狀態起，隨著空氣噴射噴嘴35停止空氣噴射，緯線之端部2a不再受到保持，其後，如上所述，緯線之端部2a於離開織口之位置折回，由此成為以下狀態，即，由經線列之最外側之若干根經線從內側經線之位置(點A)起開始彎折，並大幅地描繪出弧線。Further, the end portion 2a of the weft is shortly after the beating (for example, until the time when the crucible reaches the most rearward position), the front end portion of the end portion 2a of the weft is the weft holding hole 38 of the weaving head 31. Keeping, therefore, as the weaving opening moves, the end portion 2a of the weft is in a state of being stretched toward the opposite side of the weaving side, and the more the portion of the weft 2 is located outside the warp row, the more Move on the opposite side of the weaving side. From this state, as the air jet nozzle 35 stops the air jet, the end portion 2a of the weft is no longer held, and thereafter, as described above, the end portion 2a of the weft is folded back at a position away from the weaving port, thereby becoming the following state. That is, a plurality of warp threads on the outermost side of the warp line are bent from the position of the inner warp (point A), and the arc is largely drawn.
接下來，說明搭載有本發明之織入邊形成裝置之橡膠加強用織物編織用織機，特別說明筘4之較佳實施方式。Next, a loom for woven fabric for reinforced fabric in which the woven edge forming apparatus of the present invention is mounted will be described, and a preferred embodiment of the crucible 4 will be specifically described.
圖6表示橡膠加強用織物編織用織機之較佳之筘4之一例。此外，省略了限制裝置20之圖示。筘4包括具有用以形成緯線引導槽8之凹部6a之多個變形筘羽6、配置於織寬方向之兩端之多個平筘羽7、配置於筘4之兩側端之側部構件(裝飾羽)11、以及上下地保持這些構件之上部構件9及下部構件10。筘4藉由筘夾12固定於搖擺之筘座13。此外，於圖6中，表示了筘4之給線側，省略了給線側相反側之圖示。Fig. 6 shows an example of a preferred crucible 4 for a woven fabric for woven fabric for rubber reinforcement. Further, the illustration of the restriction device 20 is omitted. The crucible 4 includes a plurality of deformed feathers 6 having recesses 6a for forming the weft guiding grooves 8, a plurality of flat feathers 7 disposed at both ends of the weaving width direction, and side members disposed at both side ends of the weir 4 (decorative feathers) 11, and these member upper members 9 and lower members 10 are held up and down. The crucible 4 is fixed to the rocking sill 13 by the jaws 12. Further, in Fig. 6, the line side of the crucible 4 is shown, and the illustration of the opposite side to the line side is omitted.
如圖2所示，變形筘羽6於按壓緯線2之打緯部6b之上下具有山狀之突出部，這些突出部形成凹部6a。該凹部6a於多個變形筘羽6沿著織寬方向排列之狀態下，形成圖6所示之緯線引導槽8，從投緯噴嘴16噴出之緯線2藉由空氣流於緯線引導槽8中穿行。As shown in Fig. 2, the deformed feathers 6 have mountain-like projections above the beating portion 6b of the pressing weft 2, and these projections form a recess 6a. The concave portion 6a forms a weft guide groove 8 shown in FIG. 6 in a state in which a plurality of deformed feathers 6 are arranged in the weaving width direction, and the weft 2 discharged from the weft insertion nozzle 16 flows through the weft guide groove 8 by air. Walk through.
為了使緯線之端部2a穩定地形成弧線，限制裝置20對於經線開口之限制位置較佳為接近筘之最靠前位置(打緯點)5，因此，較佳為於不與筘4接觸之情況下，儘可能靠近上述最靠前位置5地設置限制裝置20。但是，若於限制裝置20之存在範圍內，完全由變形筘羽6構成筘羽，則如圖2所示，於筘4處於最靠前位置5之狀態(筘4處於虛線所示之位置之狀態)下，限制裝置20之限制構件21、22成為進入至凹部6a之狀態，因此，無法目視凹部6a之打緯部6b與限制構件21、22之筘側前緣之間之位置關係。因此，難以儘可能地使限制裝置20接近上述最靠前位置5。In order to stably form the arc portion of the end portion 2a of the weft, the restriction position of the restriction device 20 for the warp opening is preferably close to the most forward position (the beating point) 5 of the crucible, and therefore, preferably not in contact with the crucible 4 In this case, the restriction device 20 is provided as close as possible to the most forward position 5 described above. However, if the feathers are formed entirely by the deformed plume 6 within the range of the restriction device 20, as shown in Fig. 2, the crucible 4 is in the most forward position 5 (筘4 is at the position indicated by the broken line). In the state), the restriction members 21 and 22 of the restriction device 20 are in a state of entering the concave portion 6a. Therefore, the positional relationship between the beating portion 6b of the concave portion 6a and the temporally leading edge of the restriction members 21 and 22 cannot be visually observed. Therefore, it is difficult to bring the restriction device 20 as close as possible to the above-mentioned most forward position 5.
因此，於從筘4之端部起且於織寬方向上之規定範圍內，將筘4之筘羽設為平筘羽7(參照圖6)，可不受筘羽遮擋地目視筘之最靠前位置5即打緯點與限制構件21、22之間之位置關係，並可儘可能地使限制裝置20接近打緯點。Therefore, in the predetermined range from the end of the crucible 4 and in the weaving width direction, the feather of the crucible 4 is set to the flat feather 7 (see FIG. 6), and it can be visually obscured without being obscured by the feathers. The front position 5 is the positional relationship between the beating point and the restriction members 21, 22, and the restriction device 20 can be brought close to the beating point as much as possible.
此外，一般認為於空氣噴射式織機之情況下，若平筘羽7之設置範圍過大，則會對投緯造成不良影響。關於該範圍，可根據投緯條件等考慮各種大小，但發明人進行認真研究後，結果已知：若與筘4之端部相距10mm左右，則不會對緯線2之穿行造成影響，可實現大致良好之投緯。因此，平筘羽7之設置範圍較佳為設為與筘4之端部相距10mm以下。Further, in the case of an air jet type loom, it is generally considered that if the setting range of the flat feathers 7 is too large, the weft insertion is adversely affected. With regard to the range, various sizes can be considered depending on the conditions of the weft insertion, etc., but the inventors have earnestly studied and found that if the distance from the end of the crucible 4 is about 10 mm, the effect of the weft 2 is not affected, and A generally good weft. Therefore, the setting range of the flat feathers 7 is preferably set to be 10 mm or less from the end of the crucible 4.
於圖1～圖6所示之例子中，筘4之兩端部之平筘羽7之設置範圍設為與位於筘4之兩端部之側部構件11之內側相距4mm左右，其小於上述限制構件21、22之織寬方向之尺寸(10mm)。換句話說，筘4上之平筘羽7之範圍無需與限制構件21、22之存在範圍相同，只要於使筘4位於最靠前位置5之狀態下，可目視限制構件21、22之筘側前緣與筘之打緯部6b之間之位置關係，則亦可像本實施例這樣有所不同。In the example shown in FIGS. 1 to 6, the setting range of the flat feathers 7 at both end portions of the crucible 4 is set to be about 4 mm from the inner side of the side members 11 located at both end portions of the crucible 4, which is smaller than the above. The size (10 mm) of the width direction of the members 21, 22 is restricted. In other words, the range of the flat feathers 7 on the crucible 4 need not be the same as the range in which the restriction members 21, 22 exist, as long as the crucible 4 is placed in the most forward position 5, the restriction members 21, 22 can be visually observed. The positional relationship between the side leading edge and the beating portion 6b of the crucible may be different as in the present embodiment.
此外，如上所述，有效之是使限制裝置20之於最靠近筘側限制開口之部分、即本實施例中之限制構件22、21之筘側前緣儘可能地接近筘之最靠前位置(打緯點)5，但作為該筘側前緣之位置之設定部件，例如可考慮以下之部件。Further, as described above, it is effective to make the portion of the restriction device 20 closest to the crotch side restriction opening, that is, the crotch side leading edge of the restriction members 22, 21 in the present embodiment as close as possible to the most forward position of the crotch. (Breaking point) 5, but as the setting member of the position of the leading edge of the weir side, for example, the following members can be considered.
即，將限制裝置20固定於織機之固定部之固定部件設為能夠沿著經線方向調整位置之支架等，從而使限制裝置20於經線方向上移動而設定限制構件22、21之筘側前緣之位置。再者，準備經線方向之長度不同之多個限制構件作為限制構件22、21，根據這些限制構件與安裝位置之間之關係，選擇筘側前緣最接近筘之最靠前位置(打緯點)5之限制構件。如此，本發明並不限定於將限制裝置20固定地安裝於織機之固定部上，還包括能夠於經線方向上調整位置之構件。In other words, the fixing member that fixes the restriction device 20 to the fixing portion of the loom is a bracket or the like that can adjust the position along the warp direction, and the restriction device 20 is moved in the warp direction to set the side of the restriction members 22 and 21. The position of the leading edge. Further, a plurality of restricting members having different lengths in the warp direction are prepared as the restricting members 22 and 21, and according to the relationship between the restricting members and the mounting position, the front side of the front side of the crucible is selected to be closest to the front position of the crucible (beating Point) 5 restricted members. As described above, the present invention is not limited to the fact that the restriction device 20 is fixedly attached to the fixing portion of the loom, and includes a member that can adjust the position in the warp direction.
