On the upstream side of the second passage 12, a second chain pressing member 18 that presses the fastener chain 2 placed on the second passage 12 from above is arranged. The second long chain pressing member 18 is moved in the vertical direction by the vertical movement of the fourth cylinder 16 as a pressing member operating mechanism, and the fourth cylinder 16 is arranged on the stand 30 .

在模具的上方配置有注射喷嘴33。模具具有:配置在输送路径的上方的上模具31、和配置在输送路径的下方的下模具32。下模具32具有:上游侧区域,其位于输送路径的上游侧,用于配置与间隙区域29相比位于输送路径的上游侧的后链牙列;下游侧区域,其位于输送路径的下游侧,用于配置与间隙区域29相比位于输送路径的下游侧的前链牙列;上游侧区域与下游侧区域之间的中间区域。An injection nozzle 33 is arranged above the mold. The mold has an upper mold 31 arranged above the conveyance path, and a lower mold 32 arranged below the conveyance path. The lower mold 32 has: an upstream side area located on the upstream side of the conveyance path for arranging the rear element row located on the upstream side of the conveyance path compared to the gap area 29; and a downstream side area located on the downstream side of the conveyance path. It is used to arrange the front element row located on the downstream side of the conveyance path from the gap area 29 ; the intermediate area between the upstream side area and the downstream side area.

如图2所示,在下模具32的上游侧区域,从上游侧依次具有:用于收容位于后链牙列的左右的拉链带26的左右的第一带收容槽51;第一突起52,其位于左右的第一带收容槽51的中央、向上方突出、将从第一通道11输送来的拉链长链2分成左右;后链牙列收容槽,其位于第一突起52的左右、用于收容后链牙列的端部;后型腔,其位于与后链牙列收容槽相邻的下游侧的位置,用于成型左右的后止码27,由第一型腔57和第二型腔58构成。后链牙列收容槽由第一链牙列收容槽53和第二链牙列收容槽54构成,第一链牙列收容槽53收容固定在拉链长链2的左右一方的拉链带26上的、具有第一链牙21的链牙列20;第二链牙列收容槽54收容固定在拉链长链2的左右另一方的拉链带26上的、具有第二链牙22的链牙列20。第一突起52由于在第一链牙列收容槽53和第二链牙列收容槽54之间朝向上方突出,所以能够通过第一突起52进行引导来使后链牙列的左右的链牙列20向第一链牙列收容槽53和第二链牙列收容槽54移动。As shown in Figure 2, in the upstream side region of the lower mold 32, there are sequentially from the upstream side: the first belt accommodation grooves 51 for accommodating the left and right zipper belts 26 located on the left and right sides of the rear fastener element row; Located in the center of the first belt storage groove 51 on the left and right, it protrudes upwards, and divides the long zipper chain 2 delivered from the first channel 11 into left and right; Accommodate the end of the rear chain tooth row; the rear cavity, which is located at the downstream side adjacent to the rear chain tooth row storage groove, is used to form the left and right rear stoppers 27, composed of the first cavity 57 and the second type A cavity 58 is formed. The rear chain element row storage groove is made up of the first chain element row storage groove 53 and the second chain element row storage groove 54. , the fastener element row 20 having the first fastener element 21; the second fastener element row receiving groove 54 accommodates the fastener element row 20 having the second fastener element 22 fixed on the zipper tape 26 on the other side of the left and right side of the long slide fastener chain 2 . Since the first protrusion 52 protrudes upward between the first element row receiving groove 53 and the second element row receiving groove 54, it can be guided by the first protrusion 52 to make the left and right element rows of the rear element row 20 moves to the first fastener element row storage groove 53 and the second fastener element row storage groove 54.

下游侧区域在拉链长链2的输送方向隔着中间区域与上游侧区域对称。也就是说,在下模具32的下游侧区域,从下游侧依次具有:用于收容拉链带26的左右的第二带收容槽61;第二突起62,其位于左右的第二带收容槽61的中央,向上方突出;前链牙列收容槽,其位于第二突起62的左右,收容前链牙列的端部;前型腔,其位于与前链牙列收容槽相邻的上游侧位置,用于成型左右的前止码28,由第三型腔67和第四型腔68构成。前链牙列收容槽由第三链牙列收容槽55和第四链牙列收容槽56构成,第三链牙列收容槽55收容固定在拉链长链2的左右一方的拉链带26上的具有第三链牙23的链牙列20;第四链牙列收容槽56收容固定在拉链长链2的左右另一方的拉链带26上的具有第四链牙24的链牙列20,第二突起62在第三链牙列收容槽55与第四链牙列收容槽56之间朝向上方突出。第二突起62与第一突起52具有同样的作用,即,进行引导而使得前链牙列的左右的链牙列20向第三链牙列收容槽55和第四链牙列收容槽56移动。The downstream side region is symmetrical to the upstream side region across the intermediate region in the conveyance direction of the fastener chain 2 . That is to say, in the downstream side region of the lower mold 32, there are sequentially from the downstream side: the left and right second belt receiving grooves 61 for accommodating the zipper tape 26; The center protrudes upward; the front chain element storage groove, which is located on the left and right of the second protrusion 62, accommodates the end of the front chain element row; the front cavity, which is located on the upstream side adjacent to the front chain tooth row storage groove , for forming the left and right front stop codes 28, which are composed of a third cavity 67 and a fourth cavity 68. The front chain element row storage groove is made up of the 3rd chain tooth row storage groove 55 and the 4th chain tooth row storage groove 56, and the 3rd chain tooth row storage groove 55 accommodates and is fixed on the zipper tape 26 of the left and right sides of the slide fastener long chain 2. The element row 20 with the third element 23; the element row 20 with the fourth element 24 fixed on the zipper tape 26 on the other side of the left and right side of the long zipper chain 2, the fourth element row receiving groove 56, The two protrusions 62 protrude upward between the third element row receiving groove 55 and the fourth element row receiving groove 56 . The second protrusion 62 has the same function as the first protrusion 52, that is, guides the left and right element rows 20 of the front element row to move to the third element row receiving groove 55 and the fourth element row receiving groove 56. .

另外,第一突起52和第二突起62的上端为楔形。由此,第一突起52能够引导后链牙列的左右的链牙列20而使左右的链牙列20向收容各链牙列20的第一链牙列收容槽53和第二链牙列收容槽54可靠地移动。另外,第二突起62能够引导前链牙列的左右的链牙列20而使左右的链牙列20向收容各链牙列20的第三链牙列收容槽55和第四链牙列收容槽56可靠地移动。但是,第一突起52和第二突起62的上端不限于楔形,只要能够发挥同样的作用,则还可以是其他形状。In addition, the upper ends of the first protrusion 52 and the second protrusion 62 are wedge-shaped. Thereby, the first protrusion 52 can guide the left and right fastener element rows 20 of the rear fastener element row so that the left and right fastener element rows 20 move toward the first fastener element row receiving groove 53 and the second fastener element row that accommodate each fastener element row 20 . The storage tank 54 moves reliably. In addition, the second protrusion 62 can guide the left and right fastener element rows 20 of the front fastener element row so that the left and right fastener element rows 20 are accommodated in the third fastener element row storage groove 55 and the fourth fastener element row that accommodate each fastener element row 20 . The groove 56 moves reliably. However, the upper ends of the first protrusion 52 and the second protrusion 62 are not limited to the wedge shape, and may have other shapes as long as they can exert the same function.

在下模具32的中间区域具有:设置成与第一型腔57、第二型腔58、第三型腔67以及第四型腔68连通的浇道36;设置在浇道36的左右的第一凹部34和第二凹部35。在第一凹部34的上方的位置具有第一臂45,在第二凹部35的上方的位置具有第二臂46。该第一臂45和第二臂46将间隙区域29向第一凹部34和第二凹部35按压,由此将后链牙列的端部向后型腔侧拉靠,并且将前链牙列的端部向前型腔侧拉靠。第一臂45和第二臂46通过未图示的作为动作机构的汽缸的上下动作而在上下方向移动。In the middle area of the lower mold 32 there are: runners 36 arranged to communicate with the first cavity 57 , the second cavity 58 , the third cavity 67 and the fourth cavity 68 ; The recess 34 and the second recess 35 . A first arm 45 is provided at a position above the first recess 34 , and a second arm 46 is provided at a position above the second recess 35 . The first arm 45 and the second arm 46 press the gap region 29 toward the first concave portion 34 and the second concave portion 35, thereby pulling the end of the rear element row toward the rear cavity side and pulling the front element row Pull the end against the front cavity side. The first arm 45 and the second arm 46 move in the up and down direction by the up and down movement of an air cylinder which is not shown in the figure as an operating mechanism.

另外,在上模具31设置有:与下模具32的各型腔对应的用于形成止码的未图示的型腔;与下模具32的浇道36对应的未图示的浇道;与注射喷嘴33连通的浇口(直浇口)37。In addition, the upper mold 31 is provided with: an unillustrated cavity corresponding to each cavity of the lower mold 32 for forming a stop code; an unillustrated runner corresponding to the runner 36 of the lower mold 32; A gate (sprue) 37 to which the injection nozzle 33 communicates.

另外,在输送路径的左右具有能够在接近输送路径的位置和远离输送路径的位置移动的引导部件。引导部件通过未图示的作为动作机构的汽缸而在相对于输送路径正交的左右方向上移动。引导部件具有:对配置在上游侧区域的后链牙列进行引导、由第一引导部件41和第二引导部件42构成的后引导部件;和对配置在下游侧区域的前链牙列进行引导、由第三引导部件43和第四引导部件44构成的前引导部件。后引导部件,在接近了输送路径时从上方覆盖后链牙列的端部。前引导部件在接近了输送路径时从上方覆盖前链牙列的端部。由于引导部件在输送路径的左右方向移动,所以引导部件和拉头不会接触。即,能够在带拉头的拉链长链上注塑成型止码。In addition, there are guide members movable between a position close to the conveyance path and a position away from the conveyance path on the left and right of the conveyance path. The guide member is moved in the left-right direction perpendicular to the conveyance path by an unillustrated air cylinder as an operating mechanism. The guide member has: a rear guide member that guides the rear chain element row arranged in the upstream region and is composed of a first guide member 41 and a second guide member 42; and guides the front chain element row arranged in the downstream side region. . A front guide member composed of the third guide member 43 and the fourth guide member 44 . The rear guide member covers the end of the rear element row from above when approaching the transport path. The front guide member covers the end of the front element row from above when approaching the conveyance path. Since the guide member moves in the left-right direction of the transport path, the guide member and the slider do not come into contact. That is, it is possible to injection mold the stopper on the long zipper chain with the slider.

接下来,参照图3至图9,说明本发明实施例的拉链的制造装置1的动作。此外,由于上游侧区域和下游侧区域在拉链长链2的输送方向上隔着中间区域对称,所以,在下述说明中,存在仅说明上游侧区域的情况,由于下游侧区域也是同样的,所以省略其说明。Next, the operation of the slide fastener manufacturing apparatus 1 according to the embodiment of the present invention will be described with reference to FIGS. 3 to 9 . In addition, since the upstream region and the downstream region are symmetrical across the intermediate region in the conveyance direction of the slide fastener chain 2, in the following description, only the upstream region may be described, and the downstream region is the same, so Its description is omitted.

首先,如图3所示,第一通道11和第二通道12相对于下模具32位于上方。当该第一通道11和第二通道12位于上方位置时,拉链长链2相对于第一突起52和第二突起62位于上方。由此,第一通道和第二通道向上移动而从模具排出注塑成型了止码的部分时,拉链长链不会与第一突起及第二突起接触。所以,能够快速地排出拉链长链。拉链长链2通过未图示的输送机构而在第一通道11和第二通道12上被输送。当间隙区域29被输送到规定位置、例如下模具32的上方时,输送机构停止,如图3的箭头①所示,第一长链按压部件17和第二长链按压部件18通过图1所示的第三汽缸15和第四汽缸16的下移动作而向下方移动由此将拉链长链2按压在第一通道11和第二通道12上。在该状态下,如箭头②所示,第一通道11和第二通道12通过图1所示的第一汽缸13和第二汽缸14的下移动作而朝着下模具32向下方移动使得拉链长链2与下模具32的上表面接触。First, as shown in FIG. 3 , the first channel 11 and the second channel 12 are located above the lower mold 32 . When the first channel 11 and the second channel 12 are located at the upper position, the zipper chain 2 is located at the upper side relative to the first protrusion 52 and the second protrusion 62 . As a result, when the first channel and the second channel move upward to eject the injection molded part from the mold, the zipper chain will not contact the first protrusion and the second protrusion. Therefore, the long chain of the zipper can be discharged quickly. The fastener chain 2 is conveyed on the first passage 11 and the second passage 12 by a conveyance mechanism not shown. When the gap area 29 is transported to the specified position, such as above the lower mold 32, the transport mechanism stops, as shown by the arrow ① in Figure 3, the first long-chain pressing part 17 and the second long-chain pressing part 18 pass through Figure 1. The downward movement of the third cylinder 15 and the fourth cylinder 16 shown in the figure moves downward thereby pressing the zipper chain 2 against the first channel 11 and the second channel 12 . In this state, as shown by arrow ②, the first channel 11 and the second channel 12 move downward toward the lower mold 32 by the downward movement of the first cylinder 13 and the second cylinder 14 shown in FIG. The long chain 2 is in contact with the upper surface of the lower mold 32 .

接着,图4示出了第一通道11和第二通道12移动到下方的状态。图5是在图4的状态下从上方观察上游侧区域侧的俯视图。如图4和图5所示,第一长链按压部件17将载置于第一通道11的拉链长链2按压在第一通道11上,第二长链按压部件18将载置于第二通道12的拉链长链2按压在第二通道12上。由此,当拉链长链被臂牵拉而移动时(后述)拉链长链的姿势不会被打乱。另外,后链牙列和前链牙列因第一通道11和第二通道12朝向下模具32向下方移动而朝向收容槽移动。此时,即使后链牙列与第一突起52接触、前链牙列与第二突起62接触,拉链长链的姿势也不会被打乱。拉链带26被收容在第一带收容槽51中。另外,第一突起52以使后链牙列收容在第一链牙列收容槽53和第二链牙列收容槽54中的方式将链牙列分成左右部分。Next, FIG. 4 shows a state where the first passage 11 and the second passage 12 are moved downward. FIG. 5 is a plan view of the upstream region side viewed from above in the state of FIG. 4 . As shown in Fig. 4 and Fig. 5, the first long chain pressing part 17 will press the zipper long chain 2 loaded on the first channel 11 on the first channel 11, and the second long chain pressing part 18 will be placed on the second channel. The zip chain 2 of the channel 12 is pressed against the second channel 12 . Thereby, when a fastener chain is pulled by an arm and moves (it will mention later), the posture of a fastener chain will not be disturbed. In addition, the rear chain element row and the front chain element row move toward the receiving groove due to the first channel 11 and the second channel 12 moving downward toward the lower mold 32 . At this time, even if the rear element row contacts the first protrusion 52 and the front element row contacts the second protrusion 62, the posture of the slide fastener chain will not be disturbed. The fastener tape 26 is housed in the first tape housing groove 51 . In addition, the first protrusion 52 divides the fastener element row into left and right parts so that the rear fastener element row is accommodated in the first fastener element row receiving groove 53 and the second fastener element row receiving groove 54 .

在上述状态下,第一引导部件41~第四引导部件44分别从输送路径的左右朝向第一链牙列收容槽53~第四链牙列收容槽56移动而从上方覆盖收容在各链牙列收容槽53~56中的链牙列的端部。由此,限制链牙列向上方移动。图6是表示第一引导部件41和第二引导部件42覆盖后链牙列的状态的剖视图。如图6所示,第一链牙21和第二链牙22分别被第一引导部件41和第二引导部件42从上方覆盖,从而被限制向上方移动。In the above state, the first guide member 41 to the fourth guide member 44 move from the left and right of the conveyance path toward the first element row storage groove 53 to the fourth fastener element row storage groove 56 respectively, and cover and accommodate each fastener element from above. The ends of the element rows in the row accommodation grooves 53-56. Thereby, upward movement of an element row is restricted. FIG. 6 is a cross-sectional view showing a state where the first guide member 41 and the second guide member 42 cover the rear element row. As shown in FIG. 6 , the first fastener element 21 and the second fastener element 22 are covered from above by the first guide member 41 and the second guide member 42 , respectively, so as to be restricted from moving upward.

之后,如图7所示,通过未图示的汽缸的动作,第一臂45和第二臂46朝向第一凹部34和第二凹部35下降,按压间隙区域29一直到位于间隙区域29的两端部的第一链牙21~第四链牙24分别与第一链牙列收容槽53~第四链牙列收容槽56的端部接触(参照图8)。此时,由于第一引导部件41~第四引导部件44从上方覆盖着链牙列,所以能够防止链牙列向上方起伏地变形。另外,为了使得链牙在接触链牙列收容槽的端部之前间隙区域的移动不会结束,将汽缸的冲程取得充分大,并将凹部的深度取得充分大。另外,还使得在链牙列收容槽与链牙接触后也会有适当的下压力作用于第一臂和第二臂。Afterwards, as shown in FIG. 7 , the first arm 45 and the second arm 46 descend toward the first concave portion 34 and the second concave portion 35 through the action of an unillustrated cylinder, pressing the gap area 29 until the two sides located in the gap area 29 The first fastener element 21 to the fourth fastener element 24 at the ends are in contact with the ends of the first fastener element row storage groove 53 to the fourth fastener element row storage groove 56, respectively (see FIG. 8 ). At this time, since the 1st guide member 41 - the 4th guide member 44 cover an element line from above, it can prevent that an element line deform|transforms undulatingly upward. In addition, the stroke of the cylinder is made sufficiently large, and the depth of the recess is made sufficiently large so that the movement of the gap region does not end until the fastener element contacts the end of the fastener element row housing groove. In addition, an appropriate downward force acts on the first arm and the second arm after the chain element row receiving groove contacts the chain element.

接着,如图9所示,一边维持链牙列收容槽的端部和链牙接触的状态,一边使上模具31下降而与下模具32合模,从与注射喷嘴33连通的浇口37经由浇道36向各型腔流入树脂,从而在拉链长链2上注塑成型止码,然后,使上模具31、第一臂45、第二臂46、第一长链按压部件17以及第二长链按压部件18返回原位置、即上方位置,使第一引导部件41~第四引导部件44返回原位置、即左右位置,使第一通道11及第二通道12返回原位置、即上方位置。接着,再次通过输送机构输送拉链长链2。在附着于止码的浇道被切断机构切断、并在间隙区域被切断后,成为图10所示的最终形态的拉链3。如图10所示,在拉链3的两端部成型有四个相同的止码。Next, as shown in FIG. 9 , the upper mold 31 is lowered to close the mold with the lower mold 32 while maintaining the state where the end of the element row receiving groove is in contact with the elements, and the gate 37 communicating with the injection nozzle 33 passes through Runner 36 flows into resin to each mold cavity, thereby on the zipper long chain 2 injection-molded stop code, then, make upper mold 31, first arm 45, second arm 46, first long chain pressing part 17 and second long chain The chain pressing member 18 returns to the original position, that is, the upper position, returns the first guide member 41 to the fourth guide member 44 to the original position, that is, the left and right positions, and returns the first channel 11 and the second channel 12 to the original position, that is, the upper position. Next, the long slide fastener chain 2 is conveyed again by the conveyance mechanism. After the sprue attached to the stopper is cut by the cutting mechanism and cut in the gap region, the slide fastener 3 in the final form shown in FIG. 10 is obtained. As shown in FIG. 10 , four identical stops are formed at both ends of the slide fastener 3 .

在本实施例中,以注塑成型有四个相同止码的例子进行了说明,但不限于此,也可以在间隙区域的两端部注塑成型不同的止码。另外,在本实施例中,对在事先安装有拉头的拉链长链、即所谓带拉头的拉链长链上注塑成型止码的例子进行了说明,但不限于此,也能够应用于事先没有安装拉头的拉链长链中,也就是应用于在注塑成型止码后再安装拉头的拉链长链中。In this embodiment, an example of four identical stoppers is described by injection molding, but it is not limited thereto, and different stoppers may also be injection molded at both ends of the gap region. In addition, in this embodiment, the example of injection molding the stopper on the long zipper chain with the slider installed in advance, that is, the so-called long zipper chain with a slider, has been described, but it is not limited to this, and it can also be applied to In the long zipper chain without a slider installed, that is to say, it is used in the long zipper chain installed with a slider after injection molding.

在本实施例中,作为第一通道、第二通道、第一长链按压部件、第二长链按压部件、第一~第四引导部件、第一臂以及第二臂的动作机构,列举了汽缸,但不限于此。只要能够使上述各部件在规定方向上移动,则也可以是其他的动作机构。In this embodiment, as the operating mechanism of the first channel, the second channel, the first long-chain pressing member, the second long-chain pressing member, the first to fourth guiding members, the first arm, and the second arm, Cylinder, but not limited to. Other operating mechanisms may be used as long as the above-mentioned members can be moved in predetermined directions.
