Description

拉頭的鎖定解除系統及鎖定解除方法Lock release system and lock release method of slider

本發明是有關於一種拉頭的鎖定解除系統及鎖定解除方法，且特別是有關於一種用於在基於連續的拉鍊鏈條連續地製造拉鍊的過程中將被安裝於拉鍊鏈條的拉頭的鎖定功能解除的系統及方法。The present invention relates to a lock release system and a lock release method of a slider, and more particularly, to a lock function for a slider to be attached to a fastener chain in the process of continuously manufacturing a fastener based on a continuous fastener chain Release system and method.

在基於連續的拉鍊鏈條連續地量產具有合成樹脂製嚙合元件（鏈牙）列的拉鍊的情況下，通常依序進行如下所述的加工步驟。即，在左右一對長條狀拉鍊帶的各相對緣部射出成形出合成樹脂製鏈牙列來形成拉鍊鏈條的步驟；在拉鍊鏈條的長度方向上每隔規定間隔地將鏈牙列部分地去除來形成間隔部的步驟；在拉鍊鏈條中的夾著間隔部的一部分的區域接著加強膜的步驟；對加強膜的一部分進行穿孔來形成穿孔部的步驟；射出成形出打開件的步驟；組合打開件的步驟；在與穿孔部相對應的部位沿著寬度方向切斷拉鍊鏈條的步驟；以及射出成形出上止件的步驟。In the case of serially mass-producing a slide fastener having a row of synthetic resin engaging elements (elements) based on a continuous fastener chain, the following processing steps are generally performed in order. That is, a step of forming a fastener chain by injection molding a synthetic resin element row on each opposing edge of a pair of left and right long fastener tapes; A step of removing to form a spacer; a step of attaching a reinforcing film to a region sandwiching a part of the spacer in the fastener chain; a step of perforating a part of the reinforcing film to form a perforated part; the step of injection molding an opening member; combination A step of opening a member; a step of cutting the fastener chain in the width direction at a position corresponding to the perforated portion; and a step of injection molding a top stopper.

作為拉頭的一種類型，已知具有鎖定功能的拉頭。鎖定功能通常以如下方式發揮作用：通過使鎖定構件的頂端的爪與配置在拉頭內的鏈牙列接觸，來阻止相對於拉頭鏈牙列的相對移動。鎖定構件的爪根據包含拉片相對於拉頭的姿態、位置而成為鎖定狀態或鎖定解除狀態。因此，在拉頭為具有鎖定功能類型的情況下，在使拉頭穿到上述的切斷後的拉鍊單位上的步驟中需要將拉頭在解除了鎖定功能的狀態下穿到拉鍊單位上。As one type of sliders, sliders with a locking function are known. The locking function generally acts so as to prevent relative movement with respect to the slider element row by bringing the claws of the distal end of the locking member into contact with the element row arranged in the slider. The claws of the locking member are in the locked state or the unlocked state according to the posture and position of the pull tab with respect to the slider. Therefore, when the slider is of a type having a locking function, in the step of inserting the slider onto the above-described cut fastener unit, the slider needs to be inserted into the fastener unit in a state where the locking function is released.

另外，本發明人發現，在組合打開件的步驟之前使拉頭單側穿通於在各相對緣部射出成形出鏈牙列所得到的左右一對拉鍊牙鏈帶中的一方的拉鍊牙鏈帶，並且一邊使左右拉鍊牙鏈帶的鏈牙列穿過該拉頭一邊組合打開件，由此能夠提高拉鍊的生產效率。此時，在組合打開件之前需要解除拉頭的鎖定功能。Further, the present inventors have found a fastener stringer in which one side of the slider is inserted into one of a pair of left and right fastener stringers obtained by injection-molding element rows at each opposing edge before the step of assembling the opening tool. , and the production efficiency of the slide fastener can be improved by combining the opening tool while passing the element row of the left and right fastener stringers through the slider. At this time, it is necessary to release the locking function of the slider before combining the opening members.

作為解除拉頭的鎖定功能的技術，已知如下技術：使拉頭固定，將鉤子鉤掛在被安裝於拉頭的拉片的環孔中並使鉤子移動，由此解除鎖定。另外，國際公開第2019/003318號公開了通過鎖定解除部使拉片相對於固定的拉頭移位來解除鎖定的技術。As a technique for releasing the lock function of the slider, there is known a technique of releasing the lock by fixing the slider, hooking a hook in a loop hole of a handle attached to the slider, and moving the hook. In addition, International Publication No. 2019/003318 discloses a technique of releasing the lock by displacing the pull tab with respect to the fixed slider by the lock releasing portion.

但是，上述的鎖定功能解除技術均使拉片移位，因此存在因環孔的大小等拉片的形狀不同而無法適用的情況。另外，無論哪種技術均不以被安裝於拉鍊鏈條的拉頭為對象，如果在拉鍊的製造過程中使用，則需要緻密且複雜的調整，被認為難以實現穩定操作。 [現有技術文獻] [專利文獻] However, since all of the above-mentioned locking function releasing techniques displace the handle, it may not be applied depending on the shape of the handle such as the size of the ring hole. In addition, neither technique is intended for a slider attached to a fastener chain, and if it is used in the manufacturing process of a fastener, dense and complicated adjustment is required, and it is considered that it is difficult to realize stable operation.

本發明是鑒於如上所述的問題而完成的，其目的在於提供一種不依賴於拉片的形狀而能夠對被安裝於拉鍊鏈條的拉頭進行穩定操作的拉頭的鎖定解除系統及鎖定解除方法。The present invention has been made in view of the above problems, and an object of the present invention is to provide a slider lock release system and lock release method capable of stably operating a slider attached to a fastener chain regardless of the shape of the handle .

為了解決上述問題，根據本發明的一個側面，提供一種拉頭的鎖定解除系統，其用於將被安裝於連續的拉鍊鏈條的具有鎖定功能並且安裝有拉片的拉頭的所述鎖定功能解除，所述拉頭的鎖定解除系統的特徵在於：所述拉片能夠取得使所述拉頭發揮所述鎖定功能的鎖定位置和解除所述鎖定功能的鎖定解除位置，所述鎖定解除系統包括：拉頭停止機構，其包含控制部，用於使向輸送方向上游側或向輸送方向下游側移動過程中的所述拉鍊鏈條的所述拉頭停止在規定位置處；拉片止擋件，其與停止在所述規定位置處的所述拉頭接觸或接近；以及按壓構件，其用於使接觸或接近所述拉片止擋件的所述拉頭向所述拉鍊鏈條的輸送方向上游側或輸送方向下游側移位，所述拉片止擋件針對通過所述按壓構件移位的所述拉頭限制所述拉片的移位，使所述拉片朝向所述鎖定解除位置相對地移位。In order to solve the above-mentioned problems, according to one aspect of the present invention, there is provided a slider lock release system for releasing the lock function of a slider with a lock function and a pull tab attached to a continuous zipper chain , The lock release system of the slider is characterized in that: the pull tab can obtain a lock position that enables the slider to exert the lock function and a lock release position to release the lock function, and the lock release system includes: A slider stop mechanism including a control unit for stopping the slider of the fastener chain in the process of moving to the upstream side or the downstream side in the conveying direction at a predetermined position; and a pull tab stopper which contacting or approaching the slider stopped at the predetermined position; and a pressing member for causing the slider contacting or approaching the pull-tab stopper to the upstream side in the conveying direction of the fastener chain Or the downstream side in the conveying direction is displaced, and the pull tab stopper restricts the displacement of the pull tab with respect to the slider displaced by the pressing member, so that the pull tab is relatively opposed to the lock release position. shift.

在本發明中，首先，通過拉頭停止機構使被安裝於向輸送方向上游側或向輸送方向下游側移動過程中的連續的拉鍊鏈條的拉頭停止在規定位置處。拉頭停止機構包括控制部。控制部例如通過在感測器檢測到拉頭時使拉鍊鏈條的驅動輥停止，能夠使拉頭停止在規定位置處。在拉頭停止在規定位置處之後，拉頭被按壓構件保持。此時，通過按壓構件來調整拉頭的姿態。接著，使拉片止擋件與停止在規定位置處的拉頭接觸或接近。通過按壓構件使該拉頭向輸送方向上游側或向輸送方向下游側移位。此時，拉片止擋件針對通過按壓構件來移位的拉頭限制拉片的移位。由此，使拉片相對於移位的拉頭朝向鎖定解除位置相對地移位，能夠解除鎖定功能。此外，通常，在按壓構件使拉頭移位之前，拉片位於鎖定位置，拉片相對於通過按壓構件來移位的拉頭從鎖定位置朝向鎖定解除位置相對地移位，但也可以是在按壓構件使拉頭移位之前拉片位於鎖定解除位置。即使在後者的情況下，也能夠通過相對於拉頭的相對移位而將拉片可靠地配置於鎖定解除位置。In the present invention, first, the slider attached to the continuous fastener chain in the process of moving to the upstream side in the conveying direction or the downstream side in the conveying direction is stopped at a predetermined position by the slider stop mechanism. The slider stop mechanism includes a control portion. For example, when the sensor detects the slider, the controller can stop the slider at a predetermined position by stopping the drive roller of the fastener chain. After the slider is stopped at the prescribed position, the slider is held by the pressing member. At this time, the posture of the slider is adjusted by the pressing member. Next, the pull tab stopper is brought into contact with or approached by the slider stopped at a predetermined position. The slider is displaced toward the upstream side in the conveying direction or toward the downstream side in the conveying direction by the pressing member. At this time, the pull-tab stopper restricts the displacement of the pull-tab with respect to the slider displaced by the pressing member. Thereby, the handle can be relatively displaced toward the lock release position with respect to the displaced slider, and the lock function can be released. In addition, normally, before the slider is displaced by the pressing member, the pull tab is located at the locked position, and the pull tab is relatively displaced from the locked position toward the unlocked position with respect to the slider displaced by the pressing member. The pull tab is in the unlocked position before the pressing member displaces the slider. Even in the latter case, the handle can be reliably arranged at the unlocked position by relative displacement with respect to the slider.

通常，拉頭的鎖定功能以如下方式發揮作用：通過使鎖定構件的頂端的爪（參照圖27）與拉頭內的鏈牙列接觸，來阻止拉頭相對於鏈牙列的相對移動。這樣的鎖定功能根據包括被安裝於拉頭的拉片相對於拉頭的姿態在內的位置情況而成為鎖定狀態或鎖定解除狀態。即，拉片能夠取得使拉頭發揮鎖定功能的鎖定位置和解除鎖定功能的鎖定解除位置。In general, the locking function of the slider acts so as to prevent the relative movement of the slider with respect to the element row by bringing the claw (see FIG. 27 ) at the tip of the locking member into contact with the element row in the slider. Such a lock function becomes a lock state or a lock release state according to the positional situation including the posture of the handle attached to the slider with respect to the slider. That is, the handle can acquire the lock position which makes the slider exhibit the lock function, and the lock release position which releases the lock function.

The plunger 21 is injection-molded on the zipper string 1a of the zipper string 1a, and the top stopper 22 is injection-molded on the left and right zipper string 1a, 1a of the downstream zipper unit portion 10A. In addition, the zipper unit parts ( 10A, 10B ) refer to the part of the continuous zipper chain 10 that finally becomes the single zipper 30 , and the top stopper and the opener injection molding mechanism 122 simultaneously shapes the two zipper unit parts ( 10A, 10B) One of the opening pieces (20, 21) and the other side of the top stop 22.

圖10是在拉鍊鏈條10的背面側（圖10中裡側）示出上止件及打開件射出成形機構122的下模124的俯視圖。圖11是圖10的A-A線概略截面圖。上止件及打開件射出成形機構122具備下模124、未圖示的上模、用於向下模124及上模的型腔內供給熔融樹脂的澆道125。下模124及上模的型腔被分成與插棒21、帶座棒的插座體20和2個上止件22、22對應的4個型腔部。澆道125從作為熔融樹脂的澆口的直澆道126向4個型腔部產生分叉。帶座棒的插座體20成形在上游側拉鍊單位部10B的左側的拉鍊牙鏈帶1a中的比穿孔部13靠上游側（圖10中上方）的接著有加強膜12的相對緣部。插棒21成形在上游側拉鍊單位部10B的右側的拉鍊牙鏈帶1a中的與帶座棒的插座體20對應的相對緣部。2個上止件22、22與下游側拉鍊單位部10A的左右拉鍊牙鏈帶1a、1a的鏈牙列2、2的上游側端相鄰地成形。在帶座棒的插座體20及插棒21射出成形時，4個貫通孔14中也浸透熔融樹脂，在貫通孔14內固化的樹脂將拉鍊帶1的表背的帶座棒的插座體20及插棒21連結。由此，能夠提高帶座棒的插座體20及插棒21相對於拉鍊帶1的固著力。在射出成形後的打開件（20、21）及上止件22固化後，使縮進下模124內的圖11所示的頂出銷127從下模124突出，由此能夠如圖12所示那樣使打開件（20、21）及上止件22從澆道125分離出來。接下來，如圖13所示，下模124（及上模）向拉鍊鏈條10的左右方向中的一個方向（圖13中右側）移動。由此，能夠抑制在將拉鍊鏈條10向下游輸送時拉鍊鏈條10或拉頭3與澆道125及直澆道126的接觸。FIG. 10 is a plan view showing the lower mold 124 of the top stopper and the opening tool injection molding mechanism 122 on the back side (the back side in FIG. 10 ) of the fastener chain 10 . FIG. 11 is a schematic cross-sectional view taken along the line A-A in FIG. 10 . The top stopper and opener injection molding mechanism 122 includes a lower mold 124 , an upper mold not shown, and a runner 125 for supplying molten resin into the cavity of the lower mold 124 and the upper mold. The cavity of the lower mold 124 and the upper mold is divided into four cavity parts corresponding to the plunger 21 , the socket body 20 with the seat rod, and the two upper stops 22 and 22 . The runner 125 is branched into the four cavity portions from the sprue 126 serving as a gate for molten resin. The socket body 20 with seat bar is formed on the opposite edge of the fastener stringer 1a on the left side of the upstream fastener unit portion 10B on the upstream side (upper in FIG. 10 ) of the perforated portion 13 followed by the reinforcing film 12 . The plunger 21 is formed in the opposite edge part corresponding to the socket body 20 with a seat bar in the fastener stringer 1a on the right side of the upstream side fastener unit part 10B. The two top stops 22, 22 are formed adjacent to the upstream ends of the element rows 2, 2 of the left and right fastener stringers 1a, 1a of the downstream fastener unit portion 10A. When the socket body 20 with seat bar and the plunger 21 are injection-molded, the four through holes 14 are also infiltrated with molten resin, and the resin solidified in the through holes 14 causes the socket body 20 with seat bar on the front and back of the fastener tape 1 And the plunger 21 is connected. Thereby, the fixing force of the socket body 20 with a seat bar and the plunger 21 with respect to the fastener tape 1 can be improved. After the injection-molded opening members ( 20 , 21 ) and the upper stopper 22 are cured, the ejector pins 127 shown in FIG. 11 , which are retracted into the lower mold 124 , are protruded from the lower mold 124 , thereby making it possible as shown in FIG. 12 . As shown, the opening pieces (20, 21) and the upper stop 22 are separated from the runner 125. Next, as shown in FIG. 13 , the lower mold 124 (and the upper mold) is moved to one of the left-right directions of the fastener chain 10 (the right side in FIG. 13 ). Thereby, when the fastener chain 10 is conveyed downstream, the contact between the fastener chain 10 or the slider 3 and the runner 125 and the sprue 126 can be suppressed.

FIG. 15 is a plan view showing the fastener chain 10 in a state of being conveyed downstream from the state of FIG. 14 , cut away. The chain closing mechanism 123 includes a pair of left and right rod-shaped meshing members 123a, 123a, and a drive portion (not shown) for moving each meshing member 123a in the left-right direction. The respective engagement members 123a can be moved between an initial position away from each other and an approach position in which the fastener chain 10 is brought close to each other so as to engage the left and right element rows 2 and 2 by the drive portion. Although not shown, each engaging member 123a is provided with a tape groove that accommodates the fastener tape 1 when it is in the approaching position. After the slider 3 is passed through the fastener chain 10 on one side, the left and right engaging members 123a and 123a arranged on the upstream side of the fastener chain 10 in the conveying direction are moved from the initial position to the approaching position. Move and engage a part of the left and right element rows 2, 2. By conveying the fastener chain 10 downstream while the left and right engaging members 123a and 123a are temporarily maintained at the close position, the left and right element rows 2 and 2 of the corresponding upstream fastener unit portion 10B can be closed to the upper end or the upper end. near by. Then, the left and right engaging members 123a, 123a return to the initial positions.

Whether or not the exposed top stopper 22 is normally formed can be automatically checked by an inspection mechanism using an image obtained by an imaging unit such as a camera, or an inspection mechanism using a contact or non-contact sensor. Alternatively, it can also be checked by the operator's eyes whether or not it is formed normally. The inspection by visual inspection may be performed after the fastener chain 10 is cut into the slide fastener 30 by the cutting mechanism 133 . In addition, the inspection object of the above-mentioned inspection function may include not only the upper stopper 22 but also the opening tool ( 20 , 21 ) or the lower stopper. When the above-mentioned slider 3 after combining the opening tools ( 20 , 21 ) is relatively moved to the position (see FIG. 17 ) in front of the top stopper 22 , the above-mentioned inspection of the top stopper 22 can be performed without additional pulling. The head pull-down mechanism is performed in a later step. Next, the fastener chain 10 is cut|disconnected at the site|part corresponding to the perforated part 13 by the cutting mechanism 133, and several slide fasteners 30 are obtained. For the sake of convenience, the slider 3 in a state of being pulled down from the upper stopper restricting position by the slider pull-down mechanism is shown in FIG. 17 showing the slide fastener 30 after cutting, but after the slider 3 is pulled down, the slider 3 is pulled down. The mechanism 133 is cut off. By cutting from the perforated part 13, the reinforcement film part 12a which is a part of the reinforcement film 12 remains in the upper end part of the left and right fastener stringers 1a, 1a of the slide fastener 30, and remains in the lower end part of the fastener stringer 1a, 1a There is a reinforcing film portion 12 b as a part of the reinforcing film 12 .

接著，基於附圖對本發明涉及的拉頭的鎖定解除系統及鎖定解除方法的幾個實施方式進行說明，但是本發明並不限定於這樣的實施方式。一邊使拉頭3停止在規定位置S處（參照圖20）並使左右拉鍊牙鏈帶1a、1a的鏈牙列2穿過該停止的拉頭3，一邊由上述的第3設備130的鏈條組合機構131進行帶座棒的插座體20和插棒21的組合。因此，在拉頭3對於鏈牙列2具有鎖定功能的情況下，需要將停止在規定位置S處的拉頭3的鎖定功能解除。鎖定功能通常以如下方式發揮作用：通過使鎖定構件的頂端的爪5（參照圖27）與拉頭3內的鏈牙列2接觸，來阻止拉頭3相對於鏈牙列2的相對移動。這樣的鎖定功能根據包含被安裝於拉頭3的拉片4相對於拉頭3的姿態在內的位置情況而成為鎖定狀態或鎖定解除狀態。即，拉片4能夠取得使拉頭3發揮鎖定功能的鎖定位置和解除鎖定功能的鎖定解除位置。本發明涉及的拉頭的鎖定解除系統及鎖定解除方法在通過鏈條組合機構131組合帶座棒的插座體20和插棒21之前解除拉頭3的鎖定功能。Next, some embodiments of the lock release system and the lock release method of the slider according to the present invention will be described based on the drawings, but the present invention is not limited to such embodiments. While stopping the slider 3 at a predetermined position S (see FIG. 20 ) and passing the element row 2 of the left and right fastener stringers 1 a and 1 a through the stopped slider 3 , the chain of the above-mentioned third device 130 is The combination mechanism 131 performs combination of the socket body 20 with the seat bar and the plunger 21 . Therefore, when the slider 3 has a locking function with respect to the element row 2, it is necessary to release the locking function of the slider 3 stopped at the predetermined position S. The locking function generally acts to prevent relative movement of the slider 3 with respect to the element row 2 by bringing the claw 5 (see FIG. 27 ) at the tip of the locking member into contact with the element row 2 in the slider 3 . Such a lock function becomes a lock state or a lock release state according to the positional situation including the attitude of the handle 4 attached to the slider 3 with respect to the slider 3 . That is, the handle 4 can acquire the lock position which makes the slider 3 exhibit the lock function, and the lock release position which releases the lock function. The lock release system and lock release method of the slider according to the present invention release the lock function of the slider 3 before the socket body 20 with the seat bar and the plunger 21 are combined by the chain combination mechanism 131 .

以下，還將拉鍊鏈條10中單側穿通拉頭3的左側的拉鍊牙鏈帶1a稱為「第1牙鏈帶1A」，將右側的拉鍊牙鏈帶1a稱為「第2牙鏈帶1B」。在第1牙鏈帶1A射出成形有帶座棒的插座體20，在第2牙鏈帶1B射出成形有插棒21。參照圖23、圖26等，拉頭3包含上述的鎖定功能。另外，拉頭3包括上翼板3b、下翼板3c、設置於上翼板3b的半環狀的拉片連結部3d、以及被安裝於拉片連結部3d的拉片4。此外，圖7～圖17中省略了拉片4的圖示。拉片4在基端側（與自由端相反的一側）具有環孔4a（參照圖26），拉片連結部3d穿通於該環孔4a而使拉片4與拉頭3連結。拉片4能夠以基端軸部4b（參照圖26）為中心進行轉動, 該基端軸部4b規定環孔4a的基端側。上下翼板3b、3c具有左右寬度隨著朝向輸送方向上游側即肩口（3a）側逐漸擴大的左右傾斜側部3e（參照圖24、圖28等）。後述的左右一對按壓構件190被設定為對拉頭3的上翼板3b的左右傾斜側部3e起作用。單側穿通於第1牙鏈帶1A的拉頭3以如下姿態向輸送方向上游或向輸送方向下游移動：上翼板3b朝向下方且下翼板3c朝向上方，並且左右肩口（3a）朝向輸送方向上游側且後口朝向輸送方向下游側。因此，拉片4來到拉鍊鏈條10的下方。Hereinafter, the fastener stringer 1a passing through the left side of the slider 3 on one side of the fastener chain 10 is also referred to as "1st fastener stringer 1A", and the fastener stringer 1a on the right side is referred to as "2nd fastener stringer 1B" ". The socket body 20 with the seat bar is injection-molded on the first fastener stringer 1A, and the plunger 21 is injection-molded on the second fastener stringer 1B. 23, 26, etc., the slider 3 includes the above-mentioned locking function. Moreover, the slider 3 is provided with the upper blade 3b, the lower blade 3c, the semi-annular handle connection part 3d provided in the upper blade 3b, and the handle 4 attached to the handle connection part 3d. In addition, illustration of the handle 4 is abbreviate|omitted in FIGS. 7-17. The handle 4 has a ring hole 4 a (see FIG. 26 ) on the proximal end side (the side opposite to the free end), and the handle connection portion 3 d penetrates through the ring hole 4 a to connect the handle 4 and the slider 3 . The handle 4 is rotatable around a proximal end shaft portion 4b (refer to FIG. 26 ) that defines the proximal end side of the ring hole 4a. The upper and lower wings 3b and 3c have left and right inclined side portions 3e (see FIGS. 24 , 28 , etc.) whose left and right widths gradually increase toward the upstream side in the conveying direction, that is, the shoulder ( 3 a ) side. A pair of left and right pressing members 190 to be described later are set to act on the left and right inclined side portions 3 e of the upper blade 3 b of the slider 3 . The slider 3 pierced through the first fastener tape 1A on one side moves to the upstream or downstream of the conveying direction in the following posture: the upper flap 3b faces downward, the lower flap 3c faces upward, and the left and right shoulders (3a) face the conveyance The direction upstream side and the rear port face the downstream side in the conveying direction. Therefore, the pull tab 4 comes under the fastener chain 10 .

圖18是表示由第2感測器152檢測到在大致水平的輸送路徑中向輸送方向下游移動過程中的拉鍊鏈條10的拉頭3的時刻的側面說明圖。第2感測器152將拉頭3的檢測信號發送至控制部150（參照圖21），控制部150經由輥驅動部142a（參照圖21）使此前正向旋轉的驅動輥142反向旋轉。由此，拉鍊鏈條10開始向輸送方向上游移動。在該時刻，後述的拉頭止擋件160、拉頭支承構件170及拉片止擋件180位於下方的初始位置。圖19是將圖18的時刻的拉鍊鏈條10截取示出的俯視圖，示出位於初始位置的左右一對按壓構件190。此外，在圖19、圖22、圖24、圖28及圖34中省略了鏈牙列2的圖示。在圖19的時刻，左右一對按壓構件190位於彼此遠離的初始位置。左右按壓構件190在輸送方向上位於與拉頭3停止的規定位置S（參照圖20）對應的位置、嚴格來說位於與停止在規定位置S處的拉頭3的左右傾斜側部3e對應的位置（傾斜側部對應位置）。各按壓構件190包括支承桿191、以及與支承桿191的一端側的軸部連結的圓板狀的按壓部192。支承桿191的另一端與按壓構件驅動部190a（參照圖21）連結。在輸送方向上的上述傾斜側部對應位置處，左右按壓構件190能夠移動至如下位置：各按壓部192彼此遠離的初始位置；左右按壓部192彼此靠近而與位於規定位置S處的拉頭3的傾斜側部3e接觸的保持位置（參照圖24）；和左右按壓部192從保持位置進一步彼此稍稍靠近而對拉頭3的傾斜側部3e進行按壓的按壓位置（參照圖28）。左右按壓構件190能夠在保持位置處與停止在規定位置S處的拉頭3的左右傾斜側部3e接觸來調整拉頭3的姿態。另外，左右按壓構件190通過從保持位置向按壓位置移位來對拉頭3的左右傾斜側部3e進行按壓，能夠使拉頭3向輸送方向上游側移位。18 is an explanatory side view showing the timing at which the slider 3 of the fastener chain 10 is detected by the second sensor 152 in the process of moving downstream in the conveying direction in the substantially horizontal conveying path. The 2nd sensor 152 transmits the detection signal of the slider 3 to the control part 150 (refer FIG. 21), and the control part 150 reversely rotates the driving roller 142 which rotated forwardly through the roller drive part 142a (refer FIG. 21). Thereby, the fastener chain 10 starts to move upstream in the conveyance direction. At this time, the slider stopper 160 , the slider support member 170 , and the handle stopper 180 , which will be described later, are located at the lower initial positions. FIG. 19 is a plan view showing the fastener chain 10 at the time of FIG. 18 , and shows a pair of left and right pressing members 190 located at the initial position. In addition, in FIG.19, FIG.22, FIG.24, FIG.28 and FIG.34, illustration of the element row 2 is abbreviate|omitted. At the timing of FIG. 19 , the pair of left and right pressing members 190 are in the initial positions away from each other. The right and left pressing members 190 are located at a position corresponding to a predetermined position S (refer to FIG. 20 ) at which the slider 3 is stopped in the conveying direction, strictly speaking, at a position corresponding to the left and right inclined side portions 3 e of the slider 3 stopped at the predetermined position S. position (corresponding to the inclined side). Each pressing member 190 includes a support rod 191 and a disc-shaped pressing portion 192 connected to a shaft portion on one end side of the support rod 191 . The other end of the support rod 191 is connected to the pressing member driving part 190a (see FIG. 21 ). At the positions corresponding to the above-mentioned inclined side portions in the conveying direction, the left and right pressing members 190 can be moved to the following positions: an initial position where the pressing portions 192 are separated from each other; The holding position (see FIG. 24 ) where the inclined side portions 3e of the slider 3 are in contact; and the pressing position where the left and right pressing portions 192 are slightly closer to each other from the holding position and press the inclined side portions 3e of the slider 3 (see FIG. 28 ). The left and right pressing members 190 can be brought into contact with the left and right inclined side portions 3 e of the slider 3 stopped at the predetermined position S at the holding position to adjust the posture of the slider 3 . Moreover, the right-and-left pressing member 190 can displace the slider 3 to the upstream side of a conveyance direction by pressing the left-right inclined side part 3e of the slider 3 by being displaced from a holding position to a pressing position.

圖20是表示通過拉頭停止機構使在輸送路徑中向輸送方向上游移動過程中的拉鍊鏈條10的拉頭3停止在規定位置S處的時刻的側面說明圖。圖21是表示本發明的鎖定解除系統中的控制結構的框圖。在圖18及圖20中示出了如下情況：由於拉鍊鏈條10以第2牙鏈帶1B的插棒21載置在第1牙鏈帶1A的帶座棒的插座體20上的狀態移動，所以第2牙鏈帶1B相對於第1牙鏈帶1A局部向上方偏移。圖18及圖20中的附圖標記153是構成組合機構131的一部分的插棒引導構件。插棒引導構件153是用於將第2牙鏈帶1B的插棒21向停止在規定位置S處的拉頭3的非單側穿通側（拉頭3未被安裝的一側）的肩口的近前引導的構件。圖18及圖20中的附圖標記154是對拉鍊鏈條10的移動進行導向的移動導向件。在插棒引導構件153內置有第1感測器151。如果第1感測器151檢測到靠近規定位置S的拉頭3，則將檢測信號發送至控制部150，控制部150使以下所述的動作產生。20 : is an explanatory side view which shows the timing at which the slider 3 of the fastener chain 10 in the process of moving upstream in the conveyance direction in the conveyance path is stopped at the predetermined position S by the slider stop mechanism. FIG. 21 is a block diagram showing a control structure in the lock release system of the present invention. In FIGS. 18 and 20 , since the fastener chain 10 moves in a state where the plunger 21 of the second fastener stringer 1B is placed on the socket body 20 with the seat bar of the first fastener stringer 1A, Therefore, the second fastener stringer 1B is partially displaced upward with respect to the first fastener stringer 1A. Reference numeral 153 in FIGS. 18 and 20 is a plunger guide member constituting a part of the combination mechanism 131 . The plunger guide member 153 is for guiding the plunger 21 of the second fastener stringer 1B to the shoulder of the non-unilateral penetrating side (the side where the slider 3 is not attached) of the slider 3 stopped at the predetermined position S. Member of the front guide. Reference numeral 154 in FIGS. 18 and 20 is a movement guide for guiding the movement of the fastener chain 10 . The first sensor 151 is built in the plunger guide member 153 . When the first sensor 151 detects the slider 3 approaching the predetermined position S, it transmits a detection signal to the control part 150, and the control part 150 produces|generates the following operation|movement.

控制部150經由輥驅動部142a使驅動輥142的旋轉停止。由此，拉鍊鏈條10向輸送方向上游側的移動停止，拉頭3在規定位置S處停止（步驟A）。因此，可以說第1感測器151、控制部150、輥驅動部142a、驅動輥142構成拉頭停止機構。另外，控制部150經由拉頭止擋件驅動部160a使此前位於下方的初始位置的拉頭止擋件160向上方的動作位置移動。動作位置處的拉頭止擋件160限制停止在規定位置S處的拉頭3向輸送方向上游側移動。此外，也可以通過拉頭止擋件160使拉頭3停止在規定位置S處。拉頭止擋件160也可以說是拉頭停止機構的構成部分。進一步，控制部150經由拉頭支承構件驅動部170a使此前位於下方的初始位置的拉頭支承構件170向上方的動作位置移動。如圖18所示，拉頭支承構件170具有輸送方向上游側的大致水平的拉頭支承面171和從拉頭支承面171向輸送方向下游側且向下方傾斜的拉片支承面172。動作位置處的拉頭支承構件170的拉頭支承面171與前述的左右一對按壓構件190一起發揮支承位於規定位置S處的拉頭3而調整拉頭3的姿態的作用。因此，拉頭支承構件170及按壓構件190構成姿態調整機構。動作位置處的拉頭支承構件170的拉片支承面172使被安裝於拉頭3的拉片4相對於拉頭3向輸送方向下游側偏移，並且將該拉片4以向輸送方向下游側且向下方傾斜的狀態支承。拉片4相對於位於規定位置S處的拉頭3向輸送方向下游側偏移，因此後述的拉片止擋件180不會將拉片4夾在該拉片止擋件180與拉頭3之間。另外，支承在拉頭支承構件170的拉片支承面172上的拉片4位於使拉頭3發揮鎖定功能的鎖定位置。另外進一步，控制部150經由按壓構件驅動部190a使左右按壓構件190從初始位置（參照圖19及圖22）向保持位置（參照圖24）移動。在圖20的時刻，拉片止擋件180尚位於下方的初始位置。在本實施方式中，拉片止擋件180在輸送方向上配置在拉頭止擋件160與拉頭支承構件170之間。The control part 150 stops the rotation of the drive roller 142 via the roller drive part 142a. Thereby, the movement to the upstream side of the conveyance direction of the fastener chain 10 stops, and the slider 3 stops at the predetermined position S (step A). Therefore, it can be said that the 1st sensor 151, the control part 150, the roller drive part 142a, and the drive roller 142 comprise a slider stop mechanism. Moreover, the control part 150 moves the slider stopper 160 which was previously located in the downward initial position to the upper operating position via the slider stopper driving part 160a. The slider stopper 160 at the operating position restricts the slider 3 stopped at the predetermined position S from moving to the upstream side in the conveying direction. In addition, the slider 3 may be stopped at the predetermined position S by the slider stopper 160 . The slider stopper 160 can also be said to be a constituent part of the slider stop mechanism. Furthermore, the control part 150 moves the slider support member 170 which was previously located in the downward initial position to the upper operation position via the slider support member drive part 170a. As shown in FIG. 18, the slider support member 170 has a substantially horizontal slider support surface 171 on the upstream side of the conveyance direction, and a handle support surface 172 inclined downward from the slider support surface 171 to the downstream side in the conveyance direction. The slider support surface 171 of the slider support member 170 at the operating position functions to support the slider 3 at the predetermined position S together with the aforementioned pair of left and right pressing members 190 to adjust the posture of the slider 3 . Therefore, the slider support member 170 and the pressing member 190 constitute a posture adjustment mechanism. The handle support surface 172 of the slider support member 170 at the operating position shifts the handle 4 attached to the slider 3 to the downstream side in the conveying direction with respect to the slider 3, and the handle 4 moves downstream in the conveying direction. Side and downward inclined state support. Since the handle 4 is shifted to the downstream side in the conveying direction with respect to the slider 3 located at the predetermined position S, the handle stopper 180 described later does not sandwich the handle 4 between the handle stopper 180 and the slider 3 . between. Moreover, the handle 4 supported by the handle support surface 172 of the slider support member 170 is located in the lock position which makes the slider 3 exhibit a lock function. Further, the control unit 150 moves the left and right pressing members 190 from the initial position (see FIGS. 19 and 22 ) to the holding position (see FIG. 24 ) via the pressing member driving unit 190 a. At the moment of FIG. 20 , the pull tab stopper 180 is still in the initial position below. In this embodiment, the handle stopper 180 is arrange|positioned between the slider stopper 160 and the slider support member 170 in the conveyance direction.

圖22是將拉頭3停止在規定位置S處的時刻的與圖20對應的拉鍊鏈條10截取示出的俯視圖。圖23是表示圖22的時刻的拉頭3和左右按壓構件190的正面說明圖，省略了拉鍊鏈條10的圖示。在圖22及圖23的時刻，通過控制部150使左右按壓構件190開始從初始位置向保持位置移動。圖24是將左右按壓構件190移動至保持位置的時刻的拉鍊鏈條10截取示出的俯視圖。在保持位置處，各按壓構件190的按壓部192以較弱的力與處於拉頭3下方的上翼板3b的傾斜側部3e接觸來調整拉頭3的姿態（步驟D）。在使左右按壓構件190從初始位置向保持位置移動之後，控制部150經由拉片止擋件驅動部180a使此前位於下方的初始位置的拉片止擋件180向上方的動作位置上升。由此，拉片止擋件180與規定位置S處的拉頭3接觸或接近（步驟B）（參照圖26）。此後，控制部150分別使位於動作位置的拉頭止擋件160及拉頭支承構件170返回下方的初始位置。FIG. 22 is a plan view of the fastener chain 10 corresponding to FIG. 20 when the slider 3 is stopped at the predetermined position S, and is shown by cutting. FIG. 23 is a front explanatory view showing the slider 3 and the left and right pressing members 190 at the time of FIG. 22 , and the illustration of the fastener chain 10 is omitted. At the timing of FIGS. 22 and 23 , the control unit 150 starts the movement of the left and right pressing members 190 from the initial position to the holding position. FIG. 24 is a plan view of the fastener chain 10 when the left and right pressing members 190 are moved to the holding position, which is a cutaway plan view. At the holding position, the pressing portion 192 of each pressing member 190 contacts the inclined side portion 3e of the upper flap 3b below the slider 3 with a weak force to adjust the posture of the slider 3 (step D). After moving the left and right pressing members 190 from the initial position to the holding position, the control part 150 raises the handle stopper 180 previously located at the lower initial position to the upper operating position via the handle stopper drive part 180a. Thereby, the handle stopper 180 contacts or approaches the slider 3 in the predetermined position S (step B) (refer FIG. 26). After that, the control part 150 returns the slider stopper 160 and the slider support member 170 which are located in the operating position to the initial position below, respectively.

圖25是拉片止擋件180的立體圖。圖26是表示動作位置處的拉片止擋件180與拉頭3接觸的狀態的立體圖。圖27是圖26的側面說明圖，拉片4僅示出基端軸部4b。拉片止擋件180包括向上方突出的左右2個腳部181和在2個腳部181間相對地向下方呈凹狀的凹部182。凹部182是向上方和向輸送方向下游側及輸送方向上游側開放的空間。參照圖26及圖27，動作位置處的拉片止擋件180的2個腳部181的上表面與拉頭3的上翼板3b接觸。也可以是2個腳部181的上表面與上翼板3b接近。如上所述，拉頭支承構件170的拉片支承面172使拉片4向輸送方向下游側（圖27中右側）偏移，因此拉片止擋件180的腳部181不會將拉片4夾在該腳部181與拉頭3的上翼板3b之間。由此，拉片4與動作位置處的拉片止擋件180相比配置在輸送方向下游側。在表示將拉片止擋件180適用於拉頭3的時刻的圖26中，以被大致水平地抬起的方式示出的拉片4位於鎖定位置。但是，也可以是在圖26的時刻拉片4位於鎖定解除位置。另外，動作位置處的拉片止擋件180將拉頭3的拉片連結部3d部分地收容在凹部182內。換言之，拉片止擋件180通過凹部182避開拉片連結部3d而取得動作位置。凹部182容許從圖26及圖27的狀態起向輸送方向上游側（圖27中左側）移位的拉頭3的拉片連結部3d的通過，但是不容許拉片4向輸送方向上游側移位。即，動作位置處的拉片止擋件180容許拉頭3向輸送方向上游側移位，但是對拉片4的向輸送方向上游側的移位進行限制。FIG. 25 is a perspective view of the pull tab stopper 180 . FIG. 26 is a perspective view showing a state in which the handle stopper 180 at the operating position is in contact with the slider 3 . Fig. 27 is a side explanatory view of Fig. 26, in which only the proximal end shaft portion 4b of the handle 4 is shown. The pull-tab stopper 180 includes two left and right leg portions 181 protruding upward, and a concave portion 182 that is recessed downward relative to the two leg portions 181 . The concave portion 182 is a space open upward and toward the downstream side in the conveying direction and the upstream side in the conveying direction. 26 and 27 , the upper surfaces of the two leg portions 181 of the pull tab stopper 180 at the operating position are in contact with the upper wing plate 3 b of the slider 3 . The upper surfaces of the two legs 181 may be close to the upper wing plate 3b. As described above, since the handle support surface 172 of the slider support member 170 deviates the handle 4 to the downstream side (right side in FIG. 27 ) in the conveying direction, the leg portion 181 of the handle stopper 180 does not hold the handle 4 . It is sandwiched between the leg portion 181 and the upper wing plate 3 b of the slider 3 . Thereby, the handle 4 is arrange|positioned at the conveyance direction downstream side rather than the handle stopper 180 in an operating position. In FIG. 26 which shows the time of applying the pull-tab stopper 180 to the slider 3, the pull-tab 4 shown so that it may be raised substantially horizontally is located in a locked position. However, the handle 4 may be located in the unlocking position at the timing of FIG. 26 . Moreover, the handle stopper 180 in the operating position partially accommodates the handle connection part 3d of the slider 3 in the recessed part 182. In other words, the handle stopper 180 avoids the handle connection part 3d by the recessed part 182, and takes an operating position. The recessed portion 182 allows passage of the handle connection portion 3d of the slider 3 displaced to the upstream side in the conveyance direction (left side in Fig. 27 ) from the state of FIGS. 26 and 27 , but does not allow the handle 4 to move to the upstream side in the conveyance direction. bit. That is, the handle stopper 180 in an operating position allows the displacement of the slider 3 to the upstream side of the conveyance direction, but restricts the displacement of the handle 4 to the upstream side of the conveyance direction.

圖28是將左右按壓構件190從保持位置移動至按壓位置的時刻的拉鍊鏈條10截取示出的俯視圖。通過左右按壓構件190向按壓位置移動，各按壓構件190的按壓部192對拉頭3的左右傾斜側部3e進行按壓。由此，拉頭3的傾斜側部3e相對於各按壓部192的周側面192a（參照圖23）移動，由此拉頭3向輸送方向上游側（圖28中左側）移位（步驟C）。圖29是表示通過按壓構件190使拉頭3向輸送方向上游側移位後的狀態的側視圖。圖30是將圖29的局部放大的與圖27同樣的側面說明圖。左右按壓構件190在按壓位置處對拉頭3的傾斜側部3e進行按壓，使拉頭3從圖27的位置朝向圖29及圖30的位置向輸送方向上游側（圖27及圖28中左側）移位，此時拉片止擋件180保持靜止狀態。靜止狀態的拉片止擋件180對要追隨向輸送方向上游側移位的拉頭3的拉片4向輸送方向上游側的移位進行限制，使拉頭3的拉片連結部3d內的拉片4的基端軸部4b的位置如圖29所示那樣向輸送方向下游側端或其附近的位置、即朝向鎖定解除位置相對地移位。由此，圖27所示的爪5縮進，拉頭3的鎖定功能被解除。FIG. 28 is a plan view of the fastener chain 10 when the left and right pressing members 190 are moved from the holding position to the pressing position, which is cut out and shown.
