專利文獻 Patent literature
專利文獻1：日本專利特開昭58-188249號公報 Patent Document 1: Japanese Patent Laid-Open No. SHO 58-188249
且說，專利文獻1揭示的帶狀物的間歇傳送裝置中，夾合上下的補強膜片的一對夾持器形成為一體，利用一對夾持器夾合在主框架的移送路上搬送的一對帶狀物後，同時切斷而形成補強膜片。因此，焊接於拉鏈鏈條的上下兩面的上下的補強膜片為相同的長度。 In the intermittent conveyance device of the belt disclosed in Patent Document 1, a pair of grippers that sandwich the upper and lower reinforcing diaphragms are integrally formed, and one of the grippers that are sandwiched by the pair of grippers is transported on the transfer path of the main frame. After the ribbon is cut, it is simultaneously cut to form a reinforcing membrane. Therefore, the upper and lower reinforcing diaphragms welded to the upper and lower surfaces of the fastener chain have the same length.
另一方面，拉鏈鏈條上，在安裝於鏈帶的相向的帶側緣部的鏈齒內插通芯帶。在為金屬製或合成樹脂製的拉鏈鏈齒的情況下，芯帶相對於鏈帶在表背方向上大致對稱地突出，另一方面，在為螺旋狀的拉鏈鏈齒的情況下，芯帶偏向鏈帶的表面側或背面側而突出。 On the other hand, in the fastener chain, the core tape is inserted into the fastener element attached to the opposite side edge portion of the fastener tape. In the case of a fastener element made of metal or synthetic resin, the core tape protrudes substantially symmetrically with respect to the chain in the front and back directions, and on the other hand, in the case of a spiral fastener element, the core tape It protrudes toward the front side or the back side of the chain belt.
因此，在使用螺旋狀的拉鏈鏈齒的拉鏈鏈條的情況下，若將專利文獻1記載的相同長度的一對補強膜片接著於拉鏈鏈條的空間部，則一補強膜片因芯帶而彎曲，一對補強膜片的寬度方向端面在鏈帶的表背面並不一致。因此，存在補強膜片的端面部分未被接著而產生白濁的問題，從而存在外觀上欠佳的課題。 Therefore, in the case of using a fastener chain of a spiral fastener element, when a pair of reinforcing films of the same length described in Patent Document 1 are attached to the space portion of the fastener chain, a reinforcing film is bent by the core tape. The end faces in the width direction of the pair of reinforcing diaphragms do not coincide with each other on the front and back sides of the fastener tape. Therefore, there is a problem in that the end face portion of the reinforcing film is not squeaked and white turbidity is present, and there is a problem that the appearance is unsatisfactory.
本發明鑒於所述課題而完成，其目的在於提供如下的補強膜接著裝置以及補強膜接著方法：即便在芯帶偏向鏈帶的表面側或背面側突出的情況下，亦能夠使補強膜片的寬度方向端面一致而不發生白濁地進行接著。 The present invention has been made in view of the above problems, and an object of the invention is to provide a reinforced film following device and a reinforced film following method capable of reinforced a film even when a core tape is deflected toward a front side or a back side of a chain belt.

圖1是本發明的補強膜接著裝置的要部立體圖。補強膜接著裝置10為將補強膜片16接著於安裝著未圖示的開離嵌插具的拉鏈鏈條11的空間部12的接著裝置。該補強膜接著裝置10包括拉鏈鏈條搬送單元20、感知單元24、補強膜帶供給單元30、切斷機構40、補強膜片搬送單元50、以及作為補強膜片接著單元的超音波焊接裝置90。 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view of an essential part of a reinforced membrane bonding apparatus of the present invention. The reinforcing film adhesion device 10 is an attachment device that attaches the reinforcing film 16 to the space portion 12 to which the fastener chain 11 of the insertion and insertion device (not shown) is attached. The reinforced film following device 10 includes a fastener chain transport unit 20, a sensing unit 24, a reinforced film tape supply unit 30, a cutting mechanism 40, a reinforced diaphragm transport unit 50, and an ultrasonic welding device 90 as a reinforced diaphragm follower unit.
拉鏈鏈條11具有長條的一對鏈帶13、及沿著鏈帶13的相向的帶側緣部13a安裝的拉鏈鏈齒列15。拉鏈鏈齒列15具有在拉鏈鏈條11的長度方向上相鄰的許多個螺旋狀的拉鏈鏈齒14。拉鏈鏈齒14在其內部插通芯帶18(參照圖7(a))，藉由縫線而將該芯帶18縫接在鏈帶13的帶側緣部13a的下表面。芯帶18偏靠鏈帶13的下表面側突出。 The fastener chain 11 has a long pair of chain belts 13 and a fastener element row 15 attached along the opposing belt side edge portions 13a of the fastener tape 13. The fastener element row 15 has a plurality of spiral fastener elements 14 adjacent in the longitudinal direction of the fastener chain 11. The fastener element 14 is inserted into the core tape 18 (see FIG. 7(a)), and the core tape 18 is sewn to the lower surface of the belt side edge portion 13a of the fastener tape 13 by sewing. The core tape 18 protrudes toward the lower surface side of the chain belt 13.
而且，拉鏈鏈條11上，每隔拉鏈鏈齒列15的規定的間隔，形成著去除了規定數量的拉鏈鏈齒14的空間部12。 Further, in the fastener chain 11, a space portion 12 from which a predetermined number of fastener elements 14 are removed is formed at a predetermined interval from the fastener element row 15.
另外，以後的說明中，關於拉鏈鏈條，依照所搬送的方向，上游側為搬送方向近前側，下游側為搬送方向後側。而且，拉鏈鏈條11在將鏈帶13的表面作為下表面、背面作為上表面的狀態下被搬送。 In addition, in the following description, regarding the conveyance direction, the upstream side is the conveyance direction near the front side, and the downstream side is the conveyance direction rear side. Further, the fastener chain 11 is conveyed in a state where the surface of the fastener tape 13 is the lower surface and the back surface is the upper surface.
拉鏈鏈條搬送單元20比超音波焊接裝置90的設置位置配置得靠拉鏈鏈條的11的搬送方向下游側。拉鏈鏈條搬送單元20包括在上下方向上相向配置的驅動輥21及從動輥22。驅動輥21連接於未圖示的馬達。從動輥22將拉鏈鏈條11朝向驅動輥21按壓。即，驅動輥21與從動輥22夾持拉鏈鏈條11。拉鏈鏈條搬送單元20藉由使驅動輥21旋轉驅動，而使從動輥22同步地旋轉，並且將拉鏈鏈條11朝向搬送方向下游側搬送。 The zipper chain conveying unit 20 is disposed closer to the downstream side in the conveying direction of the fastener chain 11 than the installation position of the ultrasonic welding device 90. The fastener chain conveying unit 20 includes a driving roller 21 and a driven roller 22 that are disposed to face each other in the vertical direction. The drive roller 21 is connected to a motor (not shown). The driven roller 22 presses the fastener chain 11 toward the driving roller 21. That is, the drive roller 21 and the driven roller 22 sandwich the fastener chain 11. The zipper chain conveyance unit 20 rotates the drive roller 21 to rotate the driven roller 22 in synchronization, and conveys the fastener chain 11 toward the downstream side in the conveyance direction.
感知單元24比超音波焊接裝置90的設置位置配置得靠拉鏈鏈條11的搬送方向上游側。感知單元24包括：配置於鏈帶13的上方的感知輥25，及使感知輥25在上下方向上可擺動地加以支撐的擺動桿26。感知輥25一邊與所搬送的拉鏈鏈條11的鏈帶13接觸一邊旋轉。在所搬送的拉鏈鏈條11的空間部12到達感知輥25的下方位置時，感知輥25進入空間部12。此時，感知輥25進入至形成於一對鏈帶13的帶側緣部13a間的間隙12a。藉此，感知單元24中，感知輥25向下方移動，並且擺動桿26向下方擺動，從而對空間部12進行檢測。 The sensing unit 24 is disposed on the upstream side of the transport direction of the fastener chain 11 from the installation position of the ultrasonic welding device 90. The sensing unit 24 includes a sensing roller 25 disposed above the chain belt 13 and a swinging lever 26 that allows the sensing roller 25 to swingably support in the vertical direction. The sensing roller 25 rotates while being in contact with the fastener tape 13 of the fastener chain 11 to be conveyed. When the space portion 12 of the transported fastener chain 11 reaches the position below the sensing roller 25, the sensing roller 25 enters the space portion 12. At this time, the sensing roller 25 enters the gap 12a formed between the belt side edge portions 13a of the pair of fastener tapes 13. Thereby, in the sensing unit 24, the sensing roller 25 moves downward, and the swing lever 26 swings downward to detect the space portion 12.
在由感知單元24檢測出空間部12時，拉鏈鏈條搬送單元20將拉鏈鏈條11進一步搬送規定距離。而且，在空間部12移動至俯視時與超音波焊接裝置90的位置重疊的位置時，拉鏈鏈條搬送單元20停止拉鏈鏈條11的搬送。而且，在如後述般超音波焊接裝置90的接著完成後，拉鏈鏈條搬送單元20重新開始拉鏈鏈條11的搬送。拉鏈鏈條搬送單元20重複進行所述動作，來搬送拉鏈鏈條11。 When the space unit 12 is detected by the sensing unit 24, the fastener chain transport unit 20 further transports the fastener chain 11 by a predetermined distance. Further, when the space portion 12 is moved to a position overlapping the position of the ultrasonic welding device 90 in a plan view, the fastener chain transport unit 20 stops the conveyance of the fastener chain 11. Then, after the completion of the ultrasonic welding device 90 as will be described later, the fastener chain transport unit 20 restarts the transport of the fastener chain 11. The zipper chain transport unit 20 repeats the above operation to transport the zipper chain 11.
如圖2所示，補強膜帶供給單元30配置於拉鏈鏈條11的寬度方向側方。補強膜帶供給單元30包括補強膜導引構件31、及裝卸自如地支撐補強膜導引構件31的支撐單元36。 As shown in FIG. 2, the reinforcing film tape supply unit 30 is disposed on the side in the width direction of the fastener chain 11. The reinforcing film tape supply unit 30 includes a reinforcing film guiding member 31 and a supporting unit 36 that detachably supports the reinforcing film guiding member 31.
補強膜導引構件31包括：捲繞著補強膜帶17的一對帶盤(tape reel)38a、38b，對帶盤38a、帶盤38b進行支撐的帶盤支撐部39，以及將自帶盤38a、帶盤38b抽出的補強膜帶17加以導引的導引桿35及導引頭32。 The reinforcing film guiding member 31 includes a pair of tape reels 38a and 38b around which the reinforcing film tape 17 is wound, a reel support portion 39 for supporting the reel 38a and the reel 38b, and a self-reeling disc 38a, the guide rod 35 and the seeker 32 guided by the reinforcing film strip 17 taken out by the reel 38b.
帶盤支撐部39利用其長度方向的一端旋轉自如地支撐帶盤38a，利用與一端為相反側的另一端支撐帶盤38b。導引桿35固定於帶盤支撐部39的長邊方向中間部，沿與帶盤支撐部39的長邊方向正交的方向延伸。即，導引桿35沿補強膜帶17的抽出方向延伸。導引頭32配置於導引桿35的前端側，並且相對於導引桿35而在補強膜帶17的抽出方向上相對移動自如地配設。 The reel support portion 39 rotatably supports the reel 38a by one end in the longitudinal direction thereof, and supports the reel 38b by the other end opposite to the one end. The guide rod 35 is fixed to the intermediate portion in the longitudinal direction of the reel support portion 39, and extends in a direction orthogonal to the longitudinal direction of the reel support portion 39. That is, the guide rod 35 extends in the drawing direction of the reinforcing film strip 17. The seeker 32 is disposed on the distal end side of the guide rod 35, and is relatively movably disposed in the drawing direction of the reinforcing film strip 17 with respect to the guide rod 35.
另外，補強膜帶17為由尼龍系或聚酯系等熔點相對低的合成樹脂形成的膜帶。 Further, the reinforcing film tape 17 is a film tape formed of a synthetic resin having a relatively low melting point such as a nylon-based or polyester-based material.
亦參照圖7(a)~圖7(d)，導引頭32上固定著一對軸33。一對軸33滑動自如地嵌合於設置在導引桿35的前端部的導引頭支撐部37。藉此，導引頭32得到支撐而能夠移動至與導引頭支撐部37接近的位置及背離的位置。而且，導引頭32藉由螺旋彈簧34(導引頭用彈性構件)的彈力，始終朝向與導引頭支撐部37背離的方向(補強膜帶17的抽出方向)被施力。 Referring also to Figures 7(a) through 7(d), a pair of shafts 33 are secured to the seeker 32. The pair of shafts 33 are slidably fitted to the seeker support portion 37 provided at the front end portion of the guide rod 35. Thereby, the seeker 32 is supported and can be moved to a position close to the seeker support portion 37 and a position away from it. Further, the seeker 32 is always biased in a direction away from the seeker support portion 37 (the direction in which the reinforcing film tape 17 is pulled out) by the elastic force of the coil spring 34 (elastic member for the seeker).
如圖1所示，導引頭支撐部37上形成著插通自帶盤38抽出的補強膜帶17的一對狹縫37a。各狹縫37a將補強膜帶17沿著補強膜帶17的抽出方向加以導引。 As shown in FIG. 1, the seeker support portion 37 is formed with a pair of slits 37a through which the reinforcing film tape 17 taken out from the reel 38 is inserted. Each slit 37a guides the reinforcing film tape 17 along the direction in which the reinforcing film tape 17 is taken out.
而且，導引頭32上亦形成著插通補強膜帶17的一對狹縫32a。各狹縫32a在上下方向上隔開間隔而彼此平行地配置。各狹縫32a將補強膜帶17沿著補強膜帶17的抽出方向加以導引。而且，導引頭32的前端面32c側的上下方向緣部被施以倒角32b。倒角32b以輔助切斷機構40的切斷功能的方式形成，以後進行詳述。 Further, a pair of slits 32a through which the reinforcing film tape 17 is inserted are formed also on the seeker 32. Each of the slits 32a is arranged in parallel with each other at intervals in the vertical direction. Each slit 32a guides the reinforcing film tape 17 along the direction in which the reinforcing film tape 17 is taken out. Further, the upper and lower edges of the tip end surface 32c side of the seeker 32 are chamfered 32b. The chamfer 32b is formed to assist the cutting function of the cutting mechanism 40, and will be described in detail later.
切斷機構40將補強膜帶17切斷而形成規定長度的補強膜片16。切斷機構40亦參照圖2及圖8(a)，配置於導引頭32的下方，包括利用氣缸等驅動裝置42在上下方向上受到驅動的移動刀41。即，移動刀41能夠移動至與導引頭32接近的位置及背離的位置。移動刀41藉由彈性構件44而以支撐銷43為中心向順時針方向被施力。在移動刀41上下移動時，移動刀41滑動接觸於導引頭32的前端面32c。此時，藉由彈性構件44而對移動刀 41作用下述按壓力，即，將導引頭32向與補強膜帶17的抽出方向相反的方向按壓的按壓力。 The cutting mechanism 40 cuts the reinforcing film tape 17 to form a reinforcing film 16 having a predetermined length. Referring to FIGS. 2 and 8( a ), the cutting mechanism 40 is disposed below the seeker 32 and includes a moving blade 41 that is driven in the vertical direction by a driving device 42 such as a cylinder. That is, the moving blade 41 can be moved to a position close to the seeker 32 and a position away from it. The moving blade 41 is biased in the clockwise direction around the support pin 43 by the elastic member 44. When the moving blade 41 moves up and down, the moving blade 41 is in sliding contact with the front end face 32c of the seeker 32. At this time, the moving knife is moved by the elastic member 44 41 acts as a pressing force which presses the seeker 32 in a direction opposite to the direction in which the reinforcing film tape 17 is taken out.
導引頭32的前端面32c作為刀架發揮功能。移動刀41與導引頭32協動，將自導引頭32的一對狹縫32a抽出的一對補強膜帶17切斷，而形成補強膜片16。 The front end surface 32c of the seeker 32 functions as a tool holder. The moving blade 41 cooperates with the seeker 32 to cut the pair of reinforcing film strips 17 taken out from the pair of slits 32a of the seeker 32 to form the reinforcing film 16.
另外，設置於導引頭32的前端面32c的上下緣部的倒角32b以移動刀41沿著前端面32c滑動的方式對移動刀41進行導引。而且，在移動刀41沿導引頭32的前端面32c向上方移動時，移動刀41與導引頭32作用對彼此進行按壓的按壓力。藉此，移動刀41與導引頭32能夠精度佳地將補強膜帶17切斷。 Further, the chamfer 32b provided on the upper and lower edge portions of the distal end surface 32c of the seeker 32 guides the movable blade 41 so that the movable blade 41 slides along the distal end surface 32c. Further, when the moving blade 41 moves upward along the front end surface 32c of the seeker 32, the moving blade 41 and the seeker 32 act on the pressing force for pressing each other. Thereby, the moving blade 41 and the seeker 32 can cut the reinforcing film tape 17 with high precision.
參照圖2~圖6，補強膜片搬送單元50相對於拉鏈鏈條11配設於與補強膜帶供給單元30為相反的一側。補強膜片搬送單元50包括可夾合一對補強膜帶17或一對補強膜片16的一對夾持器51(51A、51B)，使一對夾持器51A、51B沿著補強膜帶17的抽出方向移動，而搬送一對補強膜帶17或一對補強膜片16。 Referring to FIGS. 2 to 6 , the reinforcing film conveying unit 50 is disposed on the opposite side of the reinforcing film tape supply unit 30 with respect to the fastener chain 11 . The reinforcing diaphragm conveying unit 50 includes a pair of grippers 51 (51A, 51B) that can sandwich a pair of reinforcing film strips 17 or a pair of reinforcing diaphragms 16 such that the pair of grippers 51A, 51B follow the reinforcing film strip The withdrawal direction of 17 is moved, and a pair of reinforcing film tapes 17 or a pair of reinforcing films 16 are conveyed.
夾持器51包括：配設於後述的移動基台60的上表面側的上部夾持器(第1夾持器)51A，及固定於移動基台60的下表面側的下部夾持器(第2夾持器)51B。上部夾持器51A配設成相對於移動基台60能夠沿著補強膜帶17的抽出方向相對移動。下部夾持器51B固定於移動基台60，且與移動基台60成為一體地移動。 The holder 51 includes an upper holder (first holder) 51A disposed on the upper surface side of the moving base 60 to be described later, and a lower holder fixed to the lower surface side of the moving base 60 ( The second gripper) 51B. The upper gripper 51A is disposed to be relatively movable with respect to the moving base 60 in the drawing direction of the reinforcing film strip 17. The lower holder 51B is fixed to the moving base 60 and moves integrally with the moving base 60.
使移動基台60移動的基台驅動單元80包括：安裝於基 台71的前壁71a的伺服馬達72，固定於基台71的前壁71a與後壁71b之間的一對導桿73，具有螺桿軸75及滾珠螺母74的滾珠螺桿機構76。 The base drive unit 80 that moves the mobile base 60 includes: The servo motor 72 of the front wall 71a of the table 71 is fixed to a pair of guide bars 73 between the front wall 71a and the rear wall 71b of the base 71, and has a screw shaft mechanism 76 of the screw shaft 75 and the ball nut 74.
一對導桿73在前壁71a與後壁71b之間固定於與拉鏈鏈條11的搬送方向正交的方向(補強膜帶17的抽出方向)上。在一對導桿73中滑動自如地嵌合移動基台60。 The pair of guide bars 73 are fixed between the front wall 71a and the rear wall 71b in a direction orthogonal to the conveyance direction of the fastener chain 11 (the direction in which the reinforcing film tape 17 is taken out). The moving base 60 is slidably fitted into the pair of guide bars 73.
而且，螺桿軸75轉動自如地支撐於基台71的前壁71a與後壁71b之間，且經由彼此嚙合的一對齒輪77A、77B，而由伺服馬達72旋轉驅動。擰接於螺桿軸75的滾珠螺母74經由連結板79而固定於移動基台60。藉此，當藉由伺服馬達72的驅動而螺桿軸75旋轉時，連結於滾珠螺母74的移動基台60由一對導桿73導引而在與拉鏈鏈條11的搬送方向正交的方向上，即，補強膜帶17的抽出方向上，與夾持器51一併移動。 Further, the screw shaft 75 is rotatably supported between the front wall 71a and the rear wall 71b of the base 71, and is rotationally driven by the servo motor 72 via a pair of gears 77A, 77B that mesh with each other. The ball nut 74 screwed to the screw shaft 75 is fixed to the moving base 60 via the coupling plate 79. Thereby, when the screw shaft 75 is rotated by the drive of the servo motor 72, the moving base 60 coupled to the ball nut 74 is guided by the pair of guide bars 73 in the direction orthogonal to the conveying direction of the fastener chain 11. That is, the reinforcing film tape 17 is moved together with the holder 51 in the drawing direction.
另外，如圖3所示，後壁71b上安裝著限制移動基台60的移動的止動件88。 Further, as shown in FIG. 3, a stopper 88 that restricts the movement of the moving base 60 is attached to the rear wall 71b.
夾持器51因藉由伺服馬達72而移動，故能夠停止於與拉鏈鏈條11的搬送方向正交的方向上的多個任意的位置。具體而言，如圖2所示，能夠在如下四處位置停止，即，將由狹縫32a導引的一對補強膜帶17的前端利用夾持器51進行夾合的夾合位置P1，切斷補強膜帶17時的切斷位置P2，將補強膜片16利用超音波焊接裝置90焊接於拉鏈鏈條11時解除該夾合的焊接位置P3，及自超音波焊接裝置90退避的退避位置P4。 Since the gripper 51 is moved by the servo motor 72, it can stop at a plurality of arbitrary positions in the direction orthogonal to the conveyance direction of the fastener chain 11. Specifically, as shown in FIG. 2, it can be stopped at the four positions, that is, the tip end of the pair of reinforcing film tapes 17 guided by the slit 32a is cut by the sandwiching position 51 of the gripper 51, and cut off. When the reinforcing film sheet 16 is welded to the fastener chain 11 by the ultrasonic welding device 90, the cutting position P2 at the time of reinforcing the film tape 17 is released, and the retracted position P4 which is retracted from the ultrasonic welding device 90 is released.
如圖4及圖5所示，下部夾持器51B包括下部固定爪片52及下部可動爪片53。下部固定爪片52嵌合並固定於形成在移動基台60的下表面槽60a中。下表面槽60a在移動基台60的下表面左右方向大致中央處沿著補強膜帶17的抽出方向而形成。下部可動爪片53嵌合於形成在下部固定爪片52的槽52a中。槽52a沿著補強膜帶17的抽出方向形成於下部固定爪片52的下表面。 As shown in FIGS. 4 and 5, the lower holder 51B includes a lower fixing claw 52 and a lower movable claw 53. The lower fixing claw piece 52 is fitted and fixed to the lower surface groove 60a formed in the moving base 60. The lower surface groove 60a is formed along the drawing direction of the reinforcing film tape 17 at substantially the center in the left-right direction of the lower surface of the moving base 60. The lower movable claw piece 53 is fitted into the groove 52a formed in the lower fixing claw piece 52. The groove 52a is formed on the lower surface of the lower fixing claw piece 52 along the drawing direction of the reinforcing film tape 17.
下部可動爪片53的長邊方向中間部藉由支撐軸54而擺動自如地得到支承。下部可動爪片53以其前端與下部固定爪片52的前端背離的方式藉由彈簧55被施力。即，下部可動爪片53的前端與下部固定爪片52的前端背離，而形成用以夾合補強膜片16的開口部59。 The intermediate portion in the longitudinal direction of the lower movable claw piece 53 is swingably supported by the support shaft 54. The lower movable claw piece 53 is biased by the spring 55 in such a manner that its front end faces away from the front end of the lower fixed claw piece 52. That is, the front end of the lower movable claw piece 53 faces away from the front end of the lower fixed claw piece 52, and an opening portion 59 for sandwiching the reinforcing diaphragm piece 16 is formed.
而且，下部固定爪片52的槽52a中滑動自如地嵌合下部凸輪56。下部凸輪56配置於下部可動爪片53的後方(圖4中為左側)。下部凸輪56形成為大致L字形棒狀，在其前端部設置著傾斜凸輪面56a，該傾斜凸輪面56a以隨著朝向前端而高度逐漸降低的方式傾斜。傾斜凸輪面56a抵接於設置在下部可動爪片53的後部的從動件58。而且，豎立設置於下部凸輪56的後端的縱壁部56b經由連結板56c而連結於下部氣缸57的活塞桿57a。下部氣缸57安裝於固定在移動基台60的下表面的下部安裝板70D。 Further, the lower cam 56 is slidably fitted into the groove 52a of the lower fixing claw piece 52. The lower cam 56 is disposed behind the lower movable claw piece 53 (left side in FIG. 4). The lower cam 56 is formed in a substantially L-shaped rod shape, and an inclined cam surface 56a is provided at the front end portion thereof, and the inclined cam surface 56a is inclined so as to gradually decrease in height toward the tip end. The inclined cam surface 56a abuts against the follower 58 provided at the rear of the lower movable claw piece 53. Further, the vertical wall portion 56b that is erected at the rear end of the lower cam 56 is coupled to the piston rod 57a of the lower cylinder 57 via the coupling plate 56c. The lower cylinder 57 is attached to the lower mounting plate 70D fixed to the lower surface of the moving base 60.
而且，連結板56c上設置著止動件用位置調節螺桿85a。止動件用位置調節螺桿85a與止動件85c相向配置，該止動件85c安裝於固定在下部安裝板70D的L字形固定板85b上。藉此，止 動件85c限制下部氣缸57的活塞桿57a的移動，即，下部凸輪56的移動。 Further, the link plate 56c is provided with a position adjusting screw 85a for a stopper. The stopper position adjusting screw 85a is disposed to face the stopper 85c, and the stopper 85c is attached to the L-shaped fixing plate 85b fixed to the lower mounting plate 70D. Take this The movable member 85c restricts the movement of the piston rod 57a of the lower cylinder 57, that is, the movement of the lower cam 56.
利用空氣壓作動的下部氣缸57藉由拉入活塞桿57a而使下部凸輪56前進(圖4中向右方向移動)。下部凸輪56的傾斜凸輪面56a按壓從動件58，使下部可動爪片53以支撐軸54為中心而向逆時針方向擺動，藉此將開口部59閉合。 The lower cylinder 57 that is actuated by the air pressure advances the lower cam 56 by pulling in the piston rod 57a (moving in the right direction in Fig. 4). The inclined cam surface 56a of the lower cam 56 presses the follower 58 to swing the lower movable claw piece 53 counterclockwise about the support shaft 54, thereby closing the opening 59.
上部夾持器51A包括上部固定爪片62及上部可動爪片63。上部固定爪片62嵌合於形成在移動基台60的上表面的上表面槽60b中。上部固定爪片62的兩側面形成著導引槽62b，該導引槽62b供固定於移動基台60的導引板61嵌合。上部固定爪片62相對於移動基台60，沿著補強膜帶17的抽出方向滑動自如地得到支撐。 The upper holder 51A includes an upper fixing claw 62 and an upper movable claw 63. The upper fixing claw piece 62 is fitted into the upper surface groove 60b formed on the upper surface of the moving base 60. Both side faces of the upper fixing claw piece 62 are formed with guide grooves 62b for fitting to the guide plates 61 fixed to the moving base 60. The upper fixing claw piece 62 is slidably supported along the moving base 60 in the drawing direction of the reinforcing film tape 17.
上部可動爪片63嵌合於形成在上部固定爪片62的上槽62a中。上槽62a沿著補強膜帶17的抽出方向，形成於上部固定爪片62的上表面。上部可動爪片63的長邊方向中間部藉由支撐軸64而擺動自如地得到支承。上部可動爪片63以其前端與上部固定爪片62的前端背離的方式藉由彈簧65被施力。即，上部可動爪片63的前端與上部固定爪片62的前端背離而形成用以夾合補強膜片16的開口部69。 The upper movable claw piece 63 is fitted into the upper groove 62a formed in the upper fixed claw piece 62. The upper groove 62a is formed on the upper surface of the upper fixing claw piece 62 along the drawing direction of the reinforcing film tape 17. The intermediate portion in the longitudinal direction of the upper movable claw piece 63 is swingably supported by the support shaft 64. The upper movable claw piece 63 is biased by the spring 65 such that its front end faces away from the front end of the upper fixed claw piece 62. That is, the front end of the upper movable claw piece 63 faces away from the front end of the upper fixing claw piece 62 to form an opening portion 69 for sandwiching the reinforcing film piece 16.
上部固定爪片62在後端部具備彈簧室62d。彈簧室62d中，在連結板79與移動基台60之間配設著螺旋彈簧78。螺旋彈簧78相對於移動基台60而對上部固定爪片62向前方(圖4中向 右方向)施力。利用螺旋彈簧78被施力的上部固定爪片62藉由後述上部夾持器驅動單元(第1夾持器驅動單元)82的活塞桿82a抵接於定位螺桿81而得到定位。定位螺桿81自移動基台60豎立設置。此時，上部固定爪片62(上部夾持器)的前端部62c比下部固定爪片52(下部夾持器)的前端部52c以規定距離2H朝向拉鏈鏈條11突出。 The upper fixing claw piece 62 is provided with a spring chamber 62d at the rear end portion. In the spring chamber 62d, a coil spring 78 is disposed between the coupling plate 79 and the moving base 60. The coil spring 78 faces the upper fixing claw 62 with respect to the moving base 60 (in FIG. 4) Right direction) Apply force. The upper fixed claw piece 62 urged by the coil spring 78 is positioned by abutment against the positioning screw 81 by the piston rod 82a of the upper gripper drive unit (first gripper drive unit) 82 which will be described later. The positioning screw 81 is erected from the moving base 60. At this time, the front end portion 62c of the upper fixing claw piece 62 (upper holder) protrudes toward the fastener chain 11 at a predetermined distance 2H from the front end portion 52c of the lower fixing claw piece 52 (lower holder).
上部固定爪片62的上槽62a中滑動自如地嵌合有上部凸輪66。上部凸輪66形成為大致L字形棒狀，在其前端部形成著傾斜凸輪面66a，該傾斜凸輪面66a以隨著朝向前端而高度逐漸降低的方式傾斜。傾斜凸輪面66a抵接於設置在上部可動爪片63的後部的從動件68。而且，豎立設置於上部凸輪66的後端的縱壁部66b經由連結板66c而連結於上部氣缸67的活塞桿67a。上部氣缸67安裝於一體固定在上部固定爪片62的上表面的上部安裝板70U。 An upper cam 66 is slidably fitted into the upper groove 62a of the upper fixing claw piece 62. The upper cam 66 is formed in a substantially L-shaped rod shape, and an inclined cam surface 66a is formed at the front end portion thereof, and the inclined cam surface 66a is inclined so as to gradually decrease in height toward the tip end. The inclined cam surface 66a abuts against the follower 68 provided at the rear of the upper movable claw piece 63. Further, the vertical wall portion 66b that is erected at the rear end of the upper cam 66 is coupled to the piston rod 67a of the upper cylinder 67 via the coupling plate 66c. The upper cylinder 67 is attached to the upper mounting plate 70U integrally fixed to the upper surface of the upper fixing claw 62.
而且，連結板66c上設置著止動件用位置調節螺桿86a。 止動件用位置調節螺桿86a與止動件86c相向配置，該止動件86c安裝於固定在上部安裝板70U的L字形固定板86b。止動件86c限制上部氣缸67的活塞桿67a的移動，即，上部凸輪66的移動。 Further, the link plate 66c is provided with a position adjusting screw 86a for a stopper. The stopper position adjusting screw 86a is disposed to face the stopper 86c, and the stopper 86c is attached to the L-shaped fixing plate 86b fixed to the upper mounting plate 70U. The stopper 86c restricts the movement of the piston rod 67a of the upper cylinder 67, that is, the movement of the upper cam 66.
利用空氣壓作動的上部氣缸67藉由拉入活塞桿67a，而使上部凸輪66前進(圖4中向右方向移動)。上部凸輪66的傾斜凸輪面66a按壓從動件68。上部可動爪片63藉由以支撐軸64為中心而向順時針方向擺動，將開口部69閉合。另外，圖4中，為 了容易理解，表示下部夾持器51B將開口部59打開的狀態，上部夾持器51A將開口部69閉合的狀態，在進行實際作動時，上部夾持器51A及下部夾持器51B同步地開閉。 The upper cylinder 67, which is actuated by the air pressure, advances the upper cam 66 by pulling the piston rod 67a (moving in the right direction in Fig. 4). The inclined cam surface 66a of the upper cam 66 presses the follower 68. The upper movable claw piece 63 swings clockwise around the support shaft 64 to close the opening 69. In addition, in Figure 4, It is easy to understand that the lower gripper 51B opens the opening 59, and the upper gripper 51A closes the opening 69. When the actual operation is performed, the upper gripper 51A and the lower gripper 51B are synchronously Opening and closing.
下部夾持器51B的開口部59及上部夾持器51A的開口部69分別位於與導引頭32的一對狹縫32a面對面的位置。從而，由狹縫32a導引的一對補強膜帶17的前端可***至分別對應的開口部59、開口部69。 The opening 59 of the lower holder 51B and the opening 69 of the upper holder 51A are located at positions facing the pair of slits 32a of the seeker 32, respectively. Therefore, the front ends of the pair of reinforcing film strips 17 guided by the slits 32a can be inserted into the corresponding opening portions 59 and openings 69, respectively.
而且，當一對補強膜帶17***至開口的開口部59、開口部69時，下部氣缸57及上部氣缸67拉入活塞桿57a、活塞桿67a。藉此，下部凸輪56、上部凸輪66的傾斜凸輪面56a、傾斜凸輪面66a分別抵接於從動件58、從動件68而使下部可動爪片53及上部可動爪片63轉動，從而將開口部59、開口部69閉合。開口部59、開口部69夾合所***的一對補強膜帶17。 When the pair of reinforcing film strips 17 are inserted into the opening portion 59 and the opening portion 69 of the opening, the lower cylinder 57 and the upper cylinder 67 are pulled into the piston rod 57a and the piston rod 67a. Thereby, the lower cam 56, the inclined cam surface 56a of the upper cam 66, and the inclined cam surface 66a abut against the follower 58 and the follower 68, respectively, and the lower movable claw piece 53 and the upper movable claw piece 63 are rotated, thereby The opening 59 and the opening 69 are closed. The opening 59 and the opening 69 sandwich the pair of reinforced film tapes 17 inserted.
如圖3、圖5及圖6所示，上部夾持器驅動單元82固定於上部安裝板70U上。上部夾持器驅動單元82包括活塞桿82a及氣缸82b，活塞桿82a朝向補強膜帶17的抽出方向，即，補強膜帶供給單元30，其前端與定位螺桿81相向。 As shown in FIGS. 3, 5 and 6, the upper gripper drive unit 82 is fixed to the upper mounting plate 70U. The upper gripper drive unit 82 includes a piston rod 82a and a cylinder 82b, and the piston rod 82a faces the extraction direction of the reinforcing film strip 17, that is, the reinforcing film strip supply unit 30, the front end of which faces the positioning screw 81.
活塞桿82a包括長度調整螺母87，該長度調整螺母87擰接於形成在該活塞桿82a的前端部的外螺紋部。長度調整螺母87能夠變更活塞桿82a的實質長度。活塞桿82a藉由調節其長度，而將上部固定爪片62的前端部62c與下部固定爪片52的前端部52c的距離調節為規定距離2H。 The piston rod 82a includes a length adjusting nut 87 that is screwed to a male screw portion formed at a front end portion of the piston rod 82a. The length adjustment nut 87 can change the substantial length of the piston rod 82a. The piston rod 82a adjusts the length thereof to adjust the distance between the front end portion 62c of the upper fixing claw piece 62 and the front end portion 52c of the lower fixing claw piece 52 to a predetermined distance 2H.
定位螺桿81固定於移動基台60，自上部安裝板70U的切口部70a向上方突出，且與活塞桿82a相向。 The positioning screw 81 is fixed to the moving base 60, protrudes upward from the notch portion 70a of the upper mounting plate 70U, and faces the piston rod 82a.
而且，上部夾持器驅動單元82藉由使利用空氣壓作動的活塞桿82a伸長，而按壓定位螺桿81。藉此，上部夾持器驅動單元82使上部夾持器驅動單元82自身，即，使上部安裝板70U及上部固定爪片62抵抗螺旋彈簧78的彈力，而向與拉鏈鏈條11背離的方向移動。 Further, the upper gripper drive unit 82 presses the positioning screw 81 by elongating the piston rod 82a that is actuated by the air pressure. Thereby, the upper gripper driving unit 82 causes the upper gripper driving unit 82 itself, that is, the upper mounting plate 70U and the upper fixing claw piece 62 to move away from the zipper chain 11 against the elastic force of the coil spring 78. .
將由上部夾持器驅動單元82實現的上部固定爪片62的移動距離設定為距離H，該距離H為設定於上部固定爪片62的前端部62c與下部固定爪片52的前端部52c的規定距離2H的一半。 The moving distance of the upper fixing claw piece 62 by the upper gripper driving unit 82 is set to a distance H which is set in the front end portion 62c of the upper fixing claw piece 62 and the front end portion 52c of the lower fixing claw piece 52. Half the distance from 2H.
回到圖1，超音波焊接裝置90配置於俯視時自導引頭32抽出的一對補強膜帶17及拉鏈鏈條11交叉的位置。 Referring back to Fig. 1, the ultrasonic welding device 90 is disposed at a position where the pair of reinforcing film tapes 17 and the fastener chain 11 which are taken out from the seek head 32 in a plan view intersect.
超音波焊接裝置90包括隔著拉鏈鏈條11的搬送路徑相向配置的超音波焊頭91與砧座92。超音波焊頭91配置於拉鏈鏈條11的上方。砧座92配置於拉鏈鏈條11的下方。於砧座92的上表面，沿著拉鏈鏈條11的搬送方向設置著退避槽93(參照圖8(c))。 The ultrasonic welding device 90 includes an ultrasonic horn 91 and an anvil 92 that are disposed to face each other across a transport path of the fastener chain 11. The ultrasonic horn 91 is disposed above the fastener chain 11. The anvil 92 is disposed below the zipper chain 11. On the upper surface of the anvil 92, a retreating groove 93 is provided along the conveying direction of the fastener chain 11 (see Fig. 8(c)).
在利用超音波焊頭91與砧座92夾持拉鏈鏈條11時，退避槽93收容自鏈帶13的下表面突出的芯帶18。超音波焊接裝置90將拉鏈鏈條11、及相向配置於拉鏈鏈條11的上下表面的一對補強膜片16，利用超音波焊頭91與砧座92夾持並進行超音波加工。藉此，補強膜片16焊接於拉鏈鏈條11的上下表面。 When the fastener chain 11 is held by the ultrasonic horn 91 and the anvil 92, the escape groove 93 accommodates the core tape 18 protruding from the lower surface of the fastener tape 13. In the ultrasonic welding device 90, the fastener chain 11 and the pair of reinforcing diaphragms 16 which are disposed to face each other on the upper and lower surfaces of the fastener chain 11 are sandwiched by the ultrasonic horn 91 and the anvil 92, and subjected to ultrasonic processing. Thereby, the reinforcing film 16 is welded to the upper and lower surfaces of the fastener chain 11.
其次，參照圖7(a)~圖7(d)及圖8(a)~圖8(c)對本實施形態的補強膜接著方法進行說明。 Next, a reinforcing film following method of the present embodiment will be described with reference to Figs. 7(a) to 7(d) and Figs. 8(a) to 8(c).
另外，補強膜接著裝置10是以自以下的初始狀態開始進行作動的情況進行說明。即，夾持器51位於與拉鏈鏈條11背離的退避位置P4。而且，下部氣缸57、上部氣缸67及上部夾持器驅動單元82分別處於不作動狀態。即，下部氣缸57及上部氣缸67為各自的活塞桿57a、活塞桿67a伸長的狀態，上部夾持器51A及下部夾持器51B的開口部59、開口部69打開。而且，上部夾持器驅動單元82在活塞桿82a被拉入的狀態下，利用螺旋彈簧78的作用而抵接於定位螺桿81。藉此，如圖7(a)所示，上部夾持器51A及下部夾持器51B位於退避位置P4，上部夾持器51A藉由螺旋彈簧78的彈力而受到按壓且比下部夾持器51B以距離2H向前方突出。 In addition, the reinforced membrane bonding apparatus 10 is demonstrated by the operation from the initial state below. That is, the gripper 51 is located at the retracted position P4 that faces away from the fastener chain 11. Further, the lower cylinder 57, the upper cylinder 67, and the upper gripper drive unit 82 are each in a non-actuated state. In other words, the lower cylinder 57 and the upper cylinder 67 are in a state in which the piston rod 57a and the piston rod 67a are extended, and the opening 59 and the opening 69 of the upper holder 51A and the lower holder 51B are opened. Further, the upper gripper drive unit 82 abuts against the positioning screw 81 by the action of the coil spring 78 in a state where the piston rod 82a is pulled in. Thereby, as shown in FIG. 7(a), the upper gripper 51A and the lower gripper 51B are located at the retracted position P4, and the upper gripper 51A is pressed by the elastic force of the coil spring 78 and is lower than the lower gripper 51B. It protrudes forward at a distance of 2H.
首先，對拉鏈鏈條搬送單元20的驅動輥22進行驅動而搬送拉鏈鏈條11。當拉鏈鏈條11的空間部12到達感知輥25的位置時，藉由感知輥25進入至空間部12的間隙12a而擺動桿26擺動並檢測空間部12。 First, the drive roller 22 of the fastener chain transport unit 20 is driven to transport the fastener chain 11. When the space portion 12 of the fastener chain 11 reaches the position of the sensing roller 25, the swing lever 26 swings and detects the space portion 12 by the sensing roller 25 entering the gap 12a of the space portion 12.
在藉由感知單元24檢測出空間部12時，拉鏈鏈條搬送單元20進一步搬送拉鏈鏈條11直至空間部12位於超音波焊接裝置90的超音波焊頭91與砧座92之間而停止。藉此，拉鏈鏈條11的空間部12配置於俯視時與自補強膜帶供給單元30抽出的補強膜帶17或補強膜片16重疊的位置。 When the space unit 12 is detected by the sensing unit 24, the fastener chain transport unit 20 further transports the fastener chain 11 until the space portion 12 is positioned between the ultrasonic horn 91 of the ultrasonic welding device 90 and the anvil 92. Thereby, the space portion 12 of the fastener chain 11 is disposed at a position overlapping the reinforcing film tape 17 or the reinforcing film sheet 16 taken out from the reinforcing film tape supply unit 30 in plan view.
伺服馬達72與藉由拉鏈鏈條搬送單元20進行的拉鏈鏈條11的搬送同時地，對螺桿軸75進行旋轉驅動。藉此，固定於滾珠螺母74的移動基台60在與拉鏈鏈條11的搬送方向正交的方向上移動，上部夾持器51A及下部夾持器51B亦與移動基台60一併移動。此時，如圖7(a)所示，藉由螺旋彈簧78的彈力而向前方被施力的上部夾持器51A的前端維持比下部夾持器51B的前端以距離2H突出的狀態。 The servo motor 72 rotates the screw shaft 75 simultaneously with the conveyance of the fastener chain 11 by the fastener chain conveyance unit 20. Thereby, the moving base 60 fixed to the ball nut 74 moves in a direction orthogonal to the conveying direction of the fastener chain 11, and the upper holder 51A and the lower holder 51B also move together with the moving base 60. At this time, as shown in FIG. 7( a ), the distal end of the upper gripper 51A urged forward by the elastic force of the coil spring 78 is maintained in a state of being protruded by a distance 2H from the distal end of the lower gripper 51B.
如圖7(b)所示，夾持器51A、夾持器51B在保持著所述距離2H的前端的前後差的狀態下，移動至可夾合補強膜帶17的夾合位置P1。此時，夾持器51首先使上部夾持器51A的前端部62c抵接於補強膜帶供給單元30的導引頭32。 As shown in FIG. 7(b), the gripper 51A and the gripper 51B move to the sandwiching position P1 at which the reinforcing film tape 17 can be sandwiched while maintaining the front-rear difference of the tip end of the distance 2H. At this time, the gripper 51 first abuts the distal end portion 62c of the upper gripper 51A against the seeker 32 of the reinforcing membrane strip supply unit 30.
夾持器51與移動基台60一併進一步前進。然而，對導引頭32向圖7(b)中左方向施力的螺旋彈簧34的彈力設定得比對上部夾持器51A向右方向施力的螺旋彈簧78的彈力大，因而抵接於導引頭32的上部夾持器51A不會移動，移動基台60與下部夾持器51B一併一邊將螺旋彈簧78壓縮一邊前進。換言之，上部夾持器51A一邊壓縮螺旋彈簧78，一邊相對於下部夾持器51B向圖中左方向相對移動。伴隨該移動，上部夾持器驅動單元82的活塞桿82a與定位螺桿81背離。 The holder 51 is further advanced together with the moving base 60. However, the elastic force of the coil spring 34 that urges the seeker 32 in the left direction in FIG. 7(b) is set larger than the elastic force of the coil spring 78 that urges the upper gripper 51A in the right direction, and thus abuts on The upper gripper 51A of the seeker 32 does not move, and the moving base 60 advances while compressing the coil spring 78 together with the lower gripper 51B. In other words, the upper gripper 51A relatively moves in the left direction with respect to the lower gripper 51B while compressing the coil spring 78. Along with this movement, the piston rod 82a of the upper gripper drive unit 82 faces away from the positioning screw 81.
不久，下部夾持器51B的前端部52c亦抵接於導引頭32而按壓導引頭32。導引頭32抵抗螺旋彈簧34的彈力而向與拉鏈鏈條11的搬送方向正交的方向移動(圖7(c))。藉此，一對補 強膜帶17的前端以導引頭32移動的長度而自一對狹縫32a突出，並***至夾持器51的開口部59、開口部69。 Soon, the front end portion 52c of the lower holder 51B also abuts against the seeker 32 to press the seeker 32. The seeker 32 moves in a direction orthogonal to the conveyance direction of the fastener chain 11 against the elastic force of the coil spring 34 (FIG. 7(c)). By this, a pair of supplements The front end of the strong film tape 17 protrudes from the pair of slits 32a by the length of the movement of the seeker 32, and is inserted into the opening 59 and the opening 69 of the holder 51.
此處，下部氣缸57、及上部氣缸67將活塞桿57a、活塞桿67a拉入。藉此，下部凸輪56、上部凸輪66的傾斜凸輪面56a、傾斜凸輪面66a分別抵接於從動件58、從動件68。下部可動爪片53及上部可動爪片63抵抗彈簧55、彈簧65的彈力而轉動，從而將開口部59、開口部69閉合。藉此，上部夾持器51A及下部夾持器51B夾合自導引頭32的一對狹縫32a突出的一對補強膜帶17的前端。 Here, the lower cylinder 57 and the upper cylinder 67 pull the piston rod 57a and the piston rod 67a. Thereby, the lower cam 56 and the inclined cam surface 56a and the inclined cam surface 66a of the upper cam 66 abut against the follower 58 and the follower 68, respectively. The lower movable claw piece 53 and the upper movable claw piece 63 are rotated against the elastic force of the spring 55 and the spring 65, thereby closing the opening 59 and the opening 69. Thereby, the upper holder 51A and the lower holder 51B sandwich the front ends of the pair of reinforcing film strips 17 projecting from the pair of slits 32a of the seeker 32.
然後，使伺服馬達72逆向旋轉，使移動基台60與夾持器51一併後退。作用有螺旋彈簧34的彈力的導引頭32保持抵接於上部夾持器51A及下部夾持器51B的狀態，追隨上部夾持器51A及下部夾持器51B的移動而移動，恢復為原來的位置並抵接於未圖示的止動件，藉此停止。進而，當移動基台60後退時，下部夾持器51B的前端部52c與導引頭32背離。然而，上部夾持器51A藉由螺旋彈簧78而向前方(導引頭32方向)被施力，故前端部62c保持為抵接於導引頭32的狀態，僅移動基台60及下部夾持器51B後退。 Then, the servo motor 72 is reversely rotated to move the moving base 60 together with the holder 51. The seeker 32 that acts on the elastic force of the coil spring 34 is held in contact with the upper gripper 51A and the lower gripper 51B, and moves in accordance with the movement of the upper gripper 51A and the lower gripper 51B, and returns to the original state. The position is abutted against a stopper (not shown), thereby stopping. Further, when the moving base 60 retreats, the front end portion 52c of the lower holder 51B faces away from the seek head 32. However, the upper holder 51A is biased toward the front (in the direction of the seeker 32) by the coil spring 78, so that the front end portion 62c is held in contact with the seeker 32, and only the base 60 and the lower clamp are moved. The holder 51B moves backward.
而且，當下部夾持器51B以距離2H後退時，固定於移動基台60的定位螺桿81抵接於上部夾持器驅動單元82的活塞桿82a。而且，上部夾持器51A被按壓至固定於移動基台60的定位螺桿81而開始後退，上部夾持器51A的前端部62c與導引頭32 背離。 Further, when the lower holder 51B is retracted by the distance 2H, the positioning screw 81 fixed to the moving base 60 abuts against the piston rod 82a of the upper holder driving unit 82. Further, the upper holder 51A is pressed to the positioning screw 81 fixed to the moving base 60 to start retreating, and the front end portion 62c of the upper holder 51A and the seeker 32 are started. Deviate.
而且，如圖7(d)所示，藉由驅動伺服馬達72，於夾合位置P1夾合一對補強膜帶17的夾持器51進而後退並停止於切斷位置P2。藉此，一對補強膜帶17在前端由夾持器51夾合的狀態下，以規定長度自狹縫32a抽出。具體而言，由下部夾持器51B抽出的補強膜帶17的長度比由上部夾持器51A抽出的補強膜帶、17的長度長了距離2H。該距離2H被設定為自鏈帶13的下表面突出的芯帶18的高度H的大致2倍。 Then, as shown in FIG. 7(d), by driving the servo motor 72, the holder 51 of the pair of reinforcing film strips 17 is sandwiched at the sandwiching position P1, and then retracted and stopped at the cutting position P2. Thereby, the pair of reinforcing film tapes 17 are taken out from the slit 32a with a predetermined length in a state where the front end is sandwiched by the gripper 51. Specifically, the length of the reinforcing film tape 17 taken out by the lower gripper 51B is longer than the length of the reinforcing film tape 17 taken by the upper gripper 51A by a distance 2H. This distance 2H is set to be approximately twice the height H of the core tape 18 protruding from the lower surface of the fastener tape 13.
此處，如圖8(a)所示，切斷機構40藉由驅動裝置42使移動刀41上升。藉此，夾持器51所夾合的一對補強膜帶17沿著導引頭32的前端面32c被切斷而形成一對補強膜片16。 Here, as shown in FIG. 8(a), the cutting mechanism 40 raises the moving blade 41 by the driving device 42. Thereby, the pair of reinforcing film strips 17 sandwiched by the gripper 51 are cut along the front end surface 32c of the seeker 32 to form a pair of reinforcing diaphragms 16.
就藉由切斷機構40切斷的補強膜片16的長度(與拉鏈鏈條11的搬送方向正交的方向上的長度)而言，由上部夾持器51A夾合而朝向拉鏈鏈條11的上表面抽出的補強膜片16的長度比拉鏈鏈條11的寬度稍短。而且，由下部夾持器51B夾合而朝向拉鏈鏈條11的下表面抽出的補強膜片16的長度比前者的長度長了2H。 The length of the reinforcing film 16 cut by the cutting mechanism 40 (the length in the direction orthogonal to the conveying direction of the fastener chain 11) is sandwiched by the upper holder 51A and faces the fastener chain 11 The length of the reinforcing film 16 extracted from the surface is slightly shorter than the width of the fastener chain 11. Further, the length of the reinforcing film 16 which is sandwiched by the lower holder 51B and is drawn toward the lower surface of the fastener chain 11 is longer than the length of the former by 2H.
而且，藉由進一步驅動伺服馬達72，夾合一對補強膜片16的夾持器51移動至超音波焊接裝置90對補強膜片16的焊接位置P3。藉此，夾持器51夾合的一對補強膜片16(16a、16b)在分別與拉鏈鏈條11的上下表面相向的狀態下移動至超音波焊頭91與砧座92之間。此時，一對補強膜片16a、補強膜片16b的靠近導引頭32側的寬度方向端面一致。即，與導引頭32為相反側的 寬度方向端面為以距離2H偏離的狀態。 Further, by further driving the servo motor 72, the holder 51 that sandwiches the pair of reinforcing diaphragms 16 is moved to the welding position P3 of the reinforcing diaphragm 16 by the ultrasonic welding device 90. Thereby, the pair of reinforcing diaphragms 16 (16a, 16b) sandwiched by the gripper 51 are moved between the ultrasonic horn 91 and the anvil 92 in a state of being opposed to the upper and lower surfaces of the fastener chain 11, respectively. At this time, the end faces in the width direction of the pair of reinforcing diaphragms 16a and 16b close to the seeker 32 side coincide with each other. That is, on the opposite side of the seeker 32 The end surface in the width direction is in a state of being deviated by a distance 2H.
此處，如圖8(b)所示，上部夾持器驅動單元82使活塞桿82a伸長而按壓定位螺桿81。藉此，夾合補強膜片16a的上部夾持器51A抵抗螺旋彈簧78的彈力而後退規定距離2H的一半即距離H。藉此，由上部夾持器51A夾合的補強膜片16a的兩端位於比由下部夾持器51B夾合的補強膜片16b的兩端以H靠內側處。即，補強膜片16a與補強膜片16b進行中心對準，即，補強膜片16a、補強膜片16b的寬度方向中間部與間隙12a所位於的拉鏈鏈條11的寬度方向中間位置一致。 Here, as shown in FIG. 8(b), the upper gripper drive unit 82 extends the piston rod 82a to press the positioning screw 81. Thereby, the upper gripper 51A that sandwiches the reinforcing diaphragm 16a is retracted by a half of the predetermined distance 2H, that is, the distance H, against the elastic force of the coil spring 78. Thereby, both ends of the reinforcing film piece 16a which are sandwiched by the upper holder 51A are located on the inner side of the reinforcing film piece 16b which is sandwiched by the lower holder 51B. In other words, the reinforcing film 16a and the reinforcing film 16b are aligned in the center, that is, the intermediate portion in the width direction of the reinforcing film 16a and the reinforcing film 16b coincides with the intermediate position in the width direction of the fastener chain 11 in which the gap 12a is located.
然後，一對補強膜片16以與拉鏈鏈條11的重合位置不發生偏離的方式，藉由設置於超音波焊頭91與砧座92的未圖示的暫時擠壓機構而受到暫時擠壓。此處，下部氣缸57及上部氣缸67使活塞桿57a、活塞桿67a伸長。藉此，夾持器51將開口部59、開口部69打開而解除一對補強膜片16的夾合。然後，伺服馬達72使螺桿軸75旋轉，使夾持器51與移動基台60一併後退至退避位置P4。 Then, the pair of reinforcing diaphragms 16 are temporarily pressed by a temporary pressing mechanism (not shown) provided in the ultrasonic horn 91 and the anvil 92 so as not to deviate from the overlapping position of the fastener chain 11. Here, the lower cylinder 57 and the upper cylinder 67 extend the piston rod 57a and the piston rod 67a.

The bent portion of the core tape 18 and the reinforcing diaphragm 16b is housed in the escape groove 93 of the anvil 92.
藉此，補強膜片16b的兩端以芯帶18的高度H，而被朝向補強膜片16b的中心拉入。從而，配置於拉鏈鏈條11的上表面側及下表面側的補強膜片16a、補強膜片16b的彼此的寬度方向兩端面一致。 Thereby, both ends of the reinforcing film 16b are pulled toward the center of the reinforcing film 16b at the height H of the core tape 18. Therefore, the reinforcing film sheets 16a and the reinforcing film sheets 16b disposed on the upper surface side and the lower surface side of the fastener chain 11 are aligned at both end faces in the width direction.
一對補強膜片16a、16b在彼此的寬度方向兩端面一致的狀態下，與拉鏈鏈條11一併藉由超音波焊頭91與砧座92夾持，經超音波加工而焊接於拉鏈鏈條11的上下表面。 The pair of reinforcing diaphragms 16a and 16b are sandwiched by the ultrasonic horn 91 and the anvil 92 together with the fastener chain 11 in a state in which both end faces in the width direction thereof are aligned, and are welded to the fastener chain 11 by ultrasonic processing. Upper and lower surfaces.
