偏心輪６５は第四モータ９４が回転することで回転する。偏心輪６５の回転によって、当接部１６２は前後方向へ移動する。支持アーム１６０は当接部１６２の移動によって回転軸１４１を中心として揺動する。支持アーム１６０の揺動によって、第二プーリ２８及び第三プーリ２９は上下方向に移動する。ベルト２７は第二プーリ２８及び第三プーリ２９とともに移動する。   The eccentric wheel 65 rotates as the fourth motor 94 rotates. Due to the rotation of the eccentric ring 65, the contact portion 162 moves in the front-rear direction. The support arm 160 swings about the rotation shaft 141 as the contact portion 162 moves. As the support arm 160 swings, the second pulley 28 and the third pulley 29 move in the vertical direction. The belt 27 moves together with the second pulley 28 and the third pulley 29.

フレーム４０は第四モータ９４の角度位置を検出可能な位置検出センサ４３を固定している。偏心輪６５は中心からの距離が最大となる位置の外周に検出板６６を設けている。位置検出センサ４３は検出板６６を検出することにより第四モータ９４の所定角度位置を検出可能である。   The frame 40 fixes a position detection sensor 43 that can detect the angular position of the fourth motor 94. The eccentric wheel 65 is provided with a detection plate 66 on the outer periphery at a position where the distance from the center is maximum. The position detection sensor 43 can detect the predetermined angular position of the fourth motor 94 by detecting the detection plate 66.

図２に示す如く下移送部３８の上方では、ローラ保持部２０が円柱状の第一ローラ２２を回転可能に支持している。第一ローラ２２は、後述する支持部１７１から延びたノズル１７の後方近傍にある。   As shown in FIG. 2, the roller holding unit 20 rotatably supports the cylindrical first roller 22 above the lower transfer unit 38. The first roller 22 is in the vicinity of the rear of the nozzle 17 extending from a support portion 171 described later.

図２を参照して接着作業時における下移送部３８近傍の様子について説明する。ばね１６６の付勢力によって当接部１６２を前方に移動する。当接部１６２が前方に移動することで、ベルト２７の第一ローラ２２と対向する部分は上方に移動している。この位置ではベルト２７とノズル１７は下布を挟んで搬送する。ノズル１７から接着剤を塗布された下布とノズル１７上を通った上布は、第一ローラ２２及びベルト２７により押圧されながら搬送されることで接着しベッド部１４上を移動する。   The state in the vicinity of the lower transfer portion 38 during the bonding operation will be described with reference to FIG. The contact portion 162 is moved forward by the biasing force of the spring 166. As the contact portion 162 moves forward, the portion of the belt 27 that faces the first roller 22 moves upward. At this position, the belt 27 and the nozzle 17 convey the lower cloth. The lower cloth coated with the adhesive from the nozzle 17 and the upper cloth passing over the nozzle 17 are conveyed while being pressed by the first roller 22 and the belt 27, and move on the bed portion 14.

図２〜図７を参照して、ノズルユニット７の構造を説明する。図３に示す如く、ノズルユニット７は正面視、略Ｌ字型に形成されている。図３及び図４に示す如く、ノズルユニット７は上部に平板状の取付部１７２が設けられている。図２に示す如く、取付部１７２によりノズルユニット７は保持部８に固定される。図４に示す如く、取付部１７２の中央には接着剤が流れ込む流路１７３が形成されている。取付部１７２には螺子孔１７４，１７５が流路１７３を挟んで対角線上に設けられている。支持部１７１は取付部１７２の一端側（図３において右側）から下方に延設されている。   The structure of the nozzle unit 7 will be described with reference to FIGS. As shown in FIG. 3, the nozzle unit 7 is formed in a substantially L shape when viewed from the front. As shown in FIGS. 3 and 4, the nozzle unit 7 is provided with a flat plate-like mounting portion 172 at the top. As shown in FIG. 2, the nozzle unit 7 is fixed to the holding portion 8 by the mounting portion 172. As shown in FIG. 4, a flow path 173 into which an adhesive flows is formed in the center of the attachment portion 172. Screw holes 174 and 175 are provided on the attachment portion 172 diagonally across the flow path 173. The support portion 171 extends downward from one end side (right side in FIG. 3) of the attachment portion 172.

ノズル１７は支持部１７１下端から取付部１７２の上面と平行且つ取付部１７２の延設方向と反対側に延設されている。ノズル１７は底面が面取りされた扁平した棒状の部材である。ノズル１７内部には接着剤が流れる流路１８９（図７参照）が形成されている。支持部１７１にも流路（図示外）が形成されている。図５に示す如く、ノズル１７の底面には、接着剤を布に塗布する為の複数の吐出口１７８がノズル１７の長手方向に一列に並んでいる。ノズル１７の長手方向の両端部には内部の流路１８９（図７参照）の端部を各々塞ぐ螺子１７６，螺子１７７が螺子込まれている。図５〜図７に示す如くノズル１７の底面の布の搬送方向（図５から図７の矢印Ａ方向）の下流側の端部にノズル１７の長手方向に沿って切欠部１８０が形成されている。   The nozzle 17 extends from the lower end of the support portion 171 in parallel to the upper surface of the attachment portion 172 and on the side opposite to the extending direction of the attachment portion 172. The nozzle 17 is a flat rod-like member having a chamfered bottom surface. A flow path 189 (see FIG. 7) through which an adhesive flows is formed inside the nozzle 17. A channel (not shown) is also formed in the support portion 171. As shown in FIG. 5, on the bottom surface of the nozzle 17, a plurality of discharge ports 178 for applying an adhesive to the cloth are arranged in a line in the longitudinal direction of the nozzle 17. Screws 176 and 177 that respectively close the ends of the internal flow path 189 (see FIG. 7) are screwed into both ends of the nozzle 17 in the longitudinal direction. As shown in FIGS. 5 to 7, a notch 180 is formed along the longitudinal direction of the nozzle 17 at the downstream end of the cloth conveyance direction (the direction of arrow A in FIGS. 5 to 7) on the bottom surface of the nozzle 17. Yes.

ノズル１７の構造の詳細を図６、図７を参照して説明する。切欠部１８０の布の搬送方向（矢印Ａ方向）の下流側の端部は斜め上方に向けた斜面１８２に面取りされている。ノズル１７の底面の布の搬送方向の上流側の端部１８１は円弧状に面取りされている。ノズル１７の上面１８６は平面に形成され、上面１８６の布の搬送方向下流側の端部は斜面１８２の先端部に向けた斜面１８７となっている。この形状のノズル１７が上布と下布の間に入って、下布に接着剤を吐出する。   Details of the structure of the nozzle 17 will be described with reference to FIGS. The downstream end of the cutout portion 180 in the cloth conveyance direction (arrow A direction) is chamfered by an inclined surface 182 that faces obliquely upward. An upstream end 181 of the bottom surface of the nozzle 17 in the cloth conveying direction is chamfered in an arc shape. The upper surface 186 of the nozzle 17 is formed in a flat surface, and the end of the upper surface 186 on the downstream side in the cloth conveyance direction is a slope 187 directed toward the tip of the slope 182. The nozzle 17 having this shape enters between the upper cloth and the lower cloth, and discharges the adhesive onto the lower cloth.

図７に示す如く、切欠部１８０は布と所定間隔を空けた平面１８３と当該平面１８３と直交する壁面１８４とを有する。吐出口１７８と切欠部１８０の間には所定厚み（一例として、０．５ｍｍ）の壁１８５が設けられている。吐出口１７８の一例としては直径０．５ｍｍであり、切欠部１８０の壁面１８４の高さは０．５ｍｍである。即ち、切欠部１８０が位置する布は、ノズル１７の底面（平面１８３）と０．５ｍｍの間隔を有する。この間隔（壁面１８４の高さ）は０．５ｍｍに限られず、接着する布の特性に合わせて適宜決定する。   As shown in FIG. 7, the notch 180 includes a cloth, a plane 183 spaced apart from the cloth, and a wall surface 184 orthogonal to the plane 183. A wall 185 having a predetermined thickness (0.5 mm as an example) is provided between the discharge port 178 and the notch 180. As an example of the discharge port 178, the diameter is 0.5 mm, and the height of the wall surface 184 of the notch 180 is 0.5 mm. That is, the cloth in which the notch 180 is located has a distance of 0.5 mm from the bottom surface (plane 183) of the nozzle 17. This interval (height of the wall surface 184) is not limited to 0.5 mm, and is appropriately determined according to the characteristics of the cloth to be bonded.

以上説明したように、布接着装置１では、ノズル１７の底面の布の搬送方向下流側に切欠部１８０を形成しているので、吐出口１７８から布に接着剤を塗布してもノズル１７の底面の下流側に接着剤が付着すること及びノズル底面の布の搬送方向下流側の端部（斜面１８２等）に接着剤が付着することを防止できる。斜面１８２に接着剤が付着していない場合、布の搬送を停止しても布に接着剤が付くことを防止できる。また、吐出口１７８と切欠部１８０の間には所定厚みの壁１８５が設けられているので切欠部１８０を設けてもノズル１７の吐出口１７８が欠損することがない。   As described above, in the cloth bonding apparatus 1, the cutout portion 180 is formed on the bottom surface of the nozzle 17 on the downstream side in the cloth conveyance direction. Therefore, even if an adhesive is applied to the cloth from the discharge port 178, It is possible to prevent the adhesive from adhering to the downstream side of the bottom surface and the adhesive from adhering to the end portion (slope 182 etc.) of the nozzle bottom surface on the downstream side of the cloth conveyance direction. When the adhesive is not attached to the inclined surface 182, it is possible to prevent the adhesive from being attached to the cloth even when the conveyance of the cloth is stopped. Further, since a wall 185 having a predetermined thickness is provided between the discharge port 178 and the cutout portion 180, the discharge port 178 of the nozzle 17 is not lost even if the cutout portion 180 is provided.
