For this reason, when the first outer plate 32 is laminated on the filter plate 44, the plurality of holes 114 of the filter part 112 opens into the wide part 128, that is, the adhesive cavity 122. The large diameter hole 120 is provided at a position corresponding to the large diameter hole 110 of the filter plate 44.
　上記構造の７枚のプレート３２，３４，３６，３８，４０，４２，４４が積層され、ねじ６０によって一体化された接着剤塗布ヘッド１０は、図１に示すように、ボルト１０８によって塗布ヘッドアダプター１６に締結されている。詳しく言えば、ボルト１０８は、各プレート３２，３４，３６，３８，４０，４２，４４の大径孔７０，８０，９０，９２，１００，１１０，１２０を挿通しており、塗布ヘッドアダプター１６のガス導入路２２の開口に形成された雌ネジ部に締結されている。ちなみに、塗布ヘッドアダプター１６の接着剤塗布ヘッド１０が装着される面には、第１外プレート３２の１対の位置決め孔１２６に対応する位置に１対の突起（図示省略）が形成されており、１対の位置決め孔１２６と１対の突起とによって、接着剤塗布ヘッド１０を、塗布ヘッドアダプター１６の所定の位置に装着することが可能となっている。 As shown in FIG. 1, the adhesive application head 10 in which the seven plates 32, 34, 36, 38, 40, 42, and 44 having the above structure are stacked and integrated by the screw 60 is applied by a bolt 108 as shown in FIG. Fastened to the adapter 16. Specifically, the bolt 108 is inserted through the large-diameter holes 70, 80, 90, 92, 100, 110, 120 of the plates 32, 34, 36, 38, 40, 42, 44, and the coating head adapter 16 It is fastened to a female thread portion formed in the opening of the gas introduction path 22. Incidentally, a pair of protrusions (not shown) are formed on the surface of the coating head adapter 16 on which the adhesive coating head 10 is mounted at positions corresponding to the pair of positioning holes 126 of the first outer plate 32. The adhesive coating head 10 can be mounted at a predetermined position of the coating head adapter 16 by the pair of positioning holes 126 and the pair of protrusions.
　接着剤塗布ヘッド１０が、塗布ヘッドアダプター１６の所定の位置に装着されることで、第１外プレート３２の接着剤導入孔１２４は、塗布ヘッドアダプター１６の接着剤導入路２４に開口するようになっており、接着剤導入路２４から供給される接着剤を、接着剤キャビティ１２２に貯留することが可能となっている。また、ガス導入路２２の雌ネジ部に締結されているボルト１０８の雄ネジ部には、軸方向に延びるように溝（図示省略）が形成されており、その溝を介して、ガス導入路２２と第２外プレート３４の大径孔９０、つまり、ガスキャビティ８６とが連通している。これにより、ガス導入路２２から供給されるガスが、ガスキャビティ８６に貯留される。 When the adhesive application head 10 is mounted at a predetermined position of the application head adapter 16, the adhesive introduction hole 124 of the first outer plate 32 opens to the adhesive introduction path 24 of the application head adapter 16. Thus, the adhesive supplied from the adhesive introduction path 24 can be stored in the adhesive cavity 122. Further, a groove (not shown) is formed in the male screw portion of the bolt 108 fastened to the female screw portion of the gas introduction path 22 so as to extend in the axial direction, and the gas introduction path is interposed through the groove. 22 communicates with the large-diameter hole 90 of the second outer plate 34, that is, the gas cavity 86. Thereby, the gas supplied from the gas introduction path 22 is stored in the gas cavity 86.
　上述した構造によって、接着剤塗布ヘッド１０では、接着剤導入路２４から供給された接着剤を中央プレート３６の第１スリット７２の開口から吐出するとともに、ガス導入路２２から供給されたガスを中央プレート３６の１対の第２スリット７２の各々の開口から噴出することが可能となっている。詳しく説明すれば、図３～９でのＡＡ線における断面図である図１０に示すように、接着剤導入路２４から供給される接着剤は、図での２点鎖線に示すように、第１外プレート３２の接着剤導入孔１２４を介して、接着剤キャビティ１２２に貯留される。そして、接着剤キャビティ１２２に貯留された接着剤は、フィルタプレート４４のフィルタ部１１２、つまり、フィルタ部１１２の複数の小さな孔１１４を介して、スペースプレート４２の連通孔１０２に流入する。この際、接着剤は、フィルタ部１１２の複数の小さな孔１１４により濾過される。そして、フィルタ部１１２により濾過された接着剤が、連通孔１０２を介して、第１サイドプレート３８の小径孔９８に流入する。さらに、その小径孔９８から中央プレート３６の第１スリット７２に、接着剤が流入し、第１スリット７２の下端から吐出される。 With the above-described structure, in the adhesive application head 10, the adhesive supplied from the adhesive introduction path 24 is discharged from the opening of the first slit 72 of the center plate 36, and the gas supplied from the gas introduction path 22 is centered. It is possible to eject from each opening of the pair of second slits 72 of the plate 36. More specifically, as shown in FIG. 10 which is a cross-sectional view taken along the line AA in FIGS. 3 to 9, the adhesive supplied from the adhesive introduction path 24 is the first as shown by a two-dot chain line in the drawings. The first outer plate 32 is stored in the adhesive cavity 122 through the adhesive introduction hole 124. The adhesive stored in the adhesive cavity 122 flows into the communication hole 102 of the space plate 42 through the filter portion 112 of the filter plate 44, that is, the plurality of small holes 114 of the filter portion 112. At this time, the adhesive is filtered through the plurality of small holes 114 of the filter portion 112. Then, the adhesive filtered by the filter portion 112 flows into the small diameter hole 98 of the first side plate 38 through the communication hole 102. Further, the adhesive flows into the first slit 72 of the central plate 36 from the small diameter hole 98 and is discharged from the lower end of the first slit 72.
　また、ガス導入路２２から供給されるガスは、図での１点鎖線に示すように、７枚のプレート３２，３４，３６，３８，４０，４２，４４の大径孔７０，８０，９０，９２，１００，１１０，１２０を介して、第２外プレート３４のガスキャビティ８６に貯留される。そして、ガスキャビティ８６に貯留されたガスは、第２サイドプレート４０の長孔８４を介して、中央プレート３６の第２スリット７４に流入する。また、ガスキャビティ８６に貯留されたガスは、第２サイドプレート４０の長孔８４を介して、中央プレート３６の小径孔７６に流入し、第１サイドプレート３８の長孔９６を迂回して、中央プレート３６の第２スリット７４に流入する。このように、１つの第２スリット７４に対して、第２サイドプレート４０の長孔８４からガスが流入するとともに、第１サイドプレート３８の長孔９６からもガスが流入し、第２スリット７４の下端からガスが噴き出される。 Moreover, the gas supplied from the gas introduction path 22 is the large-diameter holes 70, 80, 90 of the seven plates 32, 34, 36, 38, 40, 42, 44 as shown by the one-dot chain line in the figure. , 92, 100, 110, 120 are stored in the gas cavity 86 of the second outer plate 34. Then, the gas stored in the gas cavity 86 flows into the second slit 74 of the center plate 36 through the long hole 84 of the second side plate 40. Further, the gas stored in the gas cavity 86 flows into the small diameter hole 76 of the center plate 36 through the long hole 84 of the second side plate 40, bypasses the long hole 96 of the first side plate 38, It flows into the second slit 74 of the center plate 36. As described above, gas flows into the second slit 74 from the long hole 84 of the second side plate 40, and also flows into the gas from the long hole 96 of the first side plate 38. Gas is spouted from the lower end of the tube.
　第１スリット７２の開口から吐出される接着剤と第２スリット７４から噴出されるガスとの流れを説明するべく、図１１に、接着剤塗布ヘッド１０の中央プレート３６における断面図を示す。第１スリット７２は、中央プレート３６の下縁に垂直な方向に延びるように形成されており、その第１スリット７２の開口１３０から接着剤１３２（２点鎖線）が吐出される。一方、第２スリット７４は、それの上端が第１スリット７２から離れるように形成されており、その第２スリット７４の開口１３４からガス１３６（１点鎖線）が、第１スリット７２の開口１３０から吐出されている接着剤１３２に向かって噴出される。この際、噴出されるガス１３６は、中央プレート３６の下縁に突出する突起部７８の側面に沿って接着剤１３２に向かって導かれるようになっている。 FIG. 11 is a cross-sectional view of the center plate 36 of the adhesive application head 10 in order to explain the flow of the adhesive discharged from the opening of the first slit 72 and the gas discharged from the second slit 74. The first slit 72 is formed to extend in a direction perpendicular to the lower edge of the center plate 36, and the adhesive 132 (two-dot chain line) is discharged from the opening 130 of the first slit 72. On the other hand, the second slit 74 is formed such that the upper end of the second slit 74 is separated from the first slit 72, and the gas 136 (one-dot chain line) passes from the opening 134 of the second slit 74 to the opening 130 of the first slit 72. It is ejected toward the adhesive 132 being discharged from. At this time, the ejected gas 136 is guided toward the adhesive 132 along the side surface of the protrusion 78 protruding to the lower edge of the center plate 36.
　詳しく説明すれば、中央プレート３６の下縁には、１対の突起部７８と第１スリット７２の開口１３０とによって構成される台形状の中央凸部１３８が形成されている。その台形状の中央凸部１３８の上底は下底より長くなっており、その上底の両端に隣接して１対の第２スリット７４が開口している。そして、その１対の第２スリット７４の開口１３４から噴出されるガスが、中央凸部１３８の両側辺に沿って流れ、第１スリット７２の開口１３０から吐出されている接着剤１３２に向かって導かれる。これにより、吐出されている接着剤１３２は、１対の第２スリット７４の開口１３４から噴出されているガス１３６によって、ファイバー状に引延ばされるとともに、蛇行することで、好適に基体１４上に接着剤が塗布されるようになっている。 More specifically, a trapezoidal central convex portion 138 formed by a pair of protrusions 78 and an opening 130 of the first slit 72 is formed on the lower edge of the central plate 36. The upper base of the trapezoidal central convex portion 138 is longer than the lower base, and a pair of second slits 74 are opened adjacent to both ends of the upper base. Then, the gas ejected from the opening 134 of the pair of second slits 74 flows along both sides of the central convex portion 138 toward the adhesive 132 discharged from the opening 130 of the first slit 72. Led. As a result, the discharged adhesive 132 is stretched into a fiber shape by the gas 136 ejected from the openings 134 of the pair of second slits 74 and is meandered so that the adhesive 132 is suitably placed on the base 14. An adhesive is applied.
　また、１つの第２スリット７４の開口１３４から噴出されるガス１３６は、２つの流れに分岐しており、１対の第２スリット７４の開口１３４からは、４つの流れのガス１３６が噴出されている。詳しく説明すれば、ガス１３６を噴出する第２スリット７４には、上述したように、第２サイドプレート４０の長孔８４からガスが流入するとともに、第１サイドプレート３８の長孔９６からもガス１３６が流入する。つまり、互いに向かい合う２つの方向からガス１３６が流入する。これにより、図１２に示すように、第１サイドプレート３８の長孔９６から流入したガス１３６ａ（１点鎖線）は、第１サイドプレート３８の凸部９４に沿って接着剤１３２（２点鎖線）に向かって導かれ、第２サイドプレート４０の長孔８４から流入したガス１３６ｂは、第２サイドプレート４０の凸部８２に沿って接着剤１３２に向かって導かれる。したがって、接着剤塗布ヘッド１０では、第１スリット７２の開口１３０から吐出されている接着剤１３２に向かって、４つの方向からガス１３６を噴出することが可能となっている。 Further, the gas 136 ejected from the opening 134 of one second slit 74 is branched into two flows, and four flows of gas 136 are ejected from the openings 134 of the pair of second slits 74. ing. More specifically, as described above, the gas flows into the second slit 74 that ejects the gas 136 from the long hole 84 of the second side plate 40 and also from the long hole 96 of the first side plate 38. 136 flows in. That is, the gas 136 flows from two directions facing each other. As a result, as shown in FIG. 12, the gas 136 a (one-dot chain line) flowing from the long hole 96 of the first side plate 38 flows along the convex portion 94 of the first side plate 38 with the adhesive 132 (two-dot chain line). ) And the gas 136b flowing from the elongated hole 84 of the second side plate 40 is guided toward the adhesive 132 along the convex portion 82 of the second side plate 40. Therefore, in the adhesive application head 10, the gas 136 can be ejected from four directions toward the adhesive 132 discharged from the opening 130 of the first slit 72.
　上述した構造によって、接着剤塗布ヘッド１０では、中央プレート３６の中央凸部１３８と、その中央凸部１３８を挟む第１サイドプレート３８の凸部９４および第２サイドプレート４０の凸部８２とによって、接着剤を吐出する接着剤ノズル１３９が構成されており、その接着剤ノズル１３９の２つの凸部８２，９４の両側部が、１対のガイド壁のように機能して、第２スリット７４の開口１３４から噴出されるガスが、吐出されている接着剤に向かって導かれる。これにより、外気の乱れ等の影響を受けることなく、確実に吐出されている接着剤に向かってガスを噴出させることが可能となる。特に、接着剤塗布ヘッド１０では、４つの方向に噴出されているガスを、吐出されている接着剤に向かって、収斂させる必要があるため、ガスをガイドする機能は非常に有効である。さらに、吐出されている接着剤１３２に向かって、４つの方向からガス１３６が噴出されることで、効果的に接着剤を蛇行させることが可能となっている。 With the structure described above, in the adhesive application head 10, the central convex portion 138 of the central plate 36, the convex portion 94 of the first side plate 38 and the convex portion 82 of the second side plate 40 sandwiching the central convex portion 138. The adhesive nozzle 139 that discharges the adhesive is configured, and both side portions of the two convex portions 82 and 94 of the adhesive nozzle 139 function as a pair of guide walls, and the second slit 74. The gas ejected from the opening 134 is guided toward the discharged adhesive. Thereby, it becomes possible to eject gas toward the adhesive agent discharged reliably, without being influenced by disturbance of outside air or the like. In particular, in the adhesive application head 10, since the gas ejected in four directions needs to be converged toward the ejected adhesive, the function of guiding the gas is very effective. Further, the gas 136 is ejected from four directions toward the discharged adhesive 132, whereby the adhesive can be effectively meandered.
　また、接着剤塗布ヘッド１０は、７枚のプレート３２，３４，３６，３８，４０，４２，４４が積層されることによって形成されており、各プレートは、比較的シンプルな形状とされている。特に、各種スリット７２，７４および各種貫通穴７０，８０等の形成は比較的容易である。このため、接着剤塗布ヘッド１０の製造コストを比較的安価なものとすることが可能となる。また、接着剤塗布ヘッド１０では、７枚のプレート３２，３４，３６，３８，４０，４２，４４がねじ６０によって一体化されることから、接着剤塗布ヘッド１０の分解および組立を容易に行うことが可能となっている。さらに、接着剤塗布ヘッド１０の部品点数は少なく、各部品の形状もシンプルなため、洗浄性は極めて高いものとなっている。 The adhesive application head 10 is formed by laminating seven plates 32, 34, 36, 38, 40, 42, and 44, and each plate has a relatively simple shape. . In particular, the formation of the various slits 72 and 74 and the various through holes 70 and 80 is relatively easy. For this reason, the manufacturing cost of the adhesive application head 10 can be made relatively inexpensive. In the adhesive application head 10, since the seven plates 32, 34, 36, 38, 40, 42, 44 are integrated by the screw 60, the adhesive application head 10 can be easily disassembled and assembled. It is possible. Furthermore, since the number of parts of the adhesive application head 10 is small and the shape of each part is simple, the cleaning performance is extremely high.
　また、接着剤塗布ヘッド１０では、第１スリット７２と小径孔９８と連通孔１０２とフィルタ部１１２とにより構成される接着剤の流通路にフィルタ部１１２が配設されている。また、フィルタ部１１２の複数の小さな孔１１４の各々の内径は、第１スリット７２の開口１３０、つまり、接着剤の吐出口の内径より小さい。これにより、接着剤塗布ヘッド１０での接着剤の詰まりなどを好適に防止することができる。特に、接着剤は、樹脂素材であり、加熱により炭化し易い。このため、装置本体２０でフィルタにより接着剤が濾過されていても、装置本体２０から接着剤塗布ヘッド１０迄の間および、接着剤塗布ヘッド１０の内部において、接着剤が炭化し、異物が生じる場合がある。このような場合であっても、接着剤塗布ヘッド１０を構成するフィルタプレート４４により、異物を除去し、接着剤塗布ヘッド１０での接着剤の詰まりなどを好適に防止することができる。 Further, in the adhesive application head 10, the filter part 112 is disposed in the adhesive flow path constituted by the first slit 72, the small diameter hole 98, the communication hole 102, and the filter part 112. The inner diameter of each of the plurality of small holes 114 of the filter unit 112 is smaller than the inner diameter of the opening 130 of the first slit 72, that is, the adhesive outlet. Thereby, clogging of the adhesive in the adhesive application head 10 can be suitably prevented. In particular, the adhesive is a resin material and is easily carbonized by heating. Therefore, even if the adhesive is filtered by the filter in the apparatus main body 20, the adhesive is carbonized between the apparatus main body 20 and the adhesive application head 10 and in the adhesive application head 10, and foreign matter is generated. There is a case. Even in such a case, foreign matter can be removed by the filter plate 44 constituting the adhesive application head 10, and clogging of the adhesive in the adhesive application head 10 can be suitably prevented.
　また、フィルタプレート４４では、複数の小さな孔１１４がエッチングにより形成されているため、大量に安価で形成できる。このため、孔１１４が異物により詰まった場合には、古いフィルタプレート４４を、新たなフィルタプレート４４に交換すればよい。 Further, in the filter plate 44, since a plurality of small holes 114 are formed by etching, they can be formed in large quantities at a low cost. For this reason, when the hole 114 is clogged with foreign matter, the old filter plate 44 may be replaced with a new filter plate 44.
　また、接着剤塗布ヘッド１０では、フィルタプレート４４と第１サイドプレート３８との間に、スペースプレート４２が介挿される。つまり、フィルタプレート４４のフィルタ部１１２と、第１サイドプレート３８の小径孔９８との間に、スペースプレート４２の連通孔１０２が位置する。これにより、フィルタ部１１２と小径孔９８との間で、連通孔１０２がスペーサーとして機能し、内径の異なるフィルタ部１１２の孔１１４から小径孔９８への接着剤の流入を適切に担保することができる。 In the adhesive application head 10, the space plate 42 is inserted between the filter plate 44 and the first side plate 38. That is, the communication hole 102 of the space plate 42 is located between the filter portion 112 of the filter plate 44 and the small diameter hole 98 of the first side plate 38. Thereby, between the filter part 112 and the small diameter hole 98, the communication hole 102 functions as a spacer, and it is possible to appropriately secure the inflow of the adhesive from the hole 114 of the filter part 112 having a different inner diameter to the small diameter hole 98. it can.
　さらに言えば、第１外プレート３２の幅広部１２８と、フィルタプレート４４のフィルタ部１１２とは、左右方向に延びるように形成されており、幅広部１２８の左右方向の長さとフィルタ部１１２の左右方向の長さとは同じとされている。このため、接着剤塗布ヘッド１０の内部において送り出される接着剤を整流し、接着剤の圧送圧力を一定にすることができる。これにより、例えば、後に説明するが、接着剤塗布ヘッドに複数の接着剤吐出口が形成されている場合に、それら複数の接着剤吐出口からの接着剤の吐出圧を一定にし、複数の接着剤吐出口から吐出される接着剤の単位時間当たりの量を均一にすることができる。なお、幅広部１２８の左右方向の長さの数値とフィルタ部１１２の左右方向の長さの数値とが同一でなくても、幅広部１２８の長さとフィルタ部１１２の長さとの差が誤差の範囲であれば、幅広部１２８の長さとフィルタ部１１２の長さとは同じである。 Furthermore, the wide portion 128 of the first outer plate 32 and the filter portion 112 of the filter plate 44 are formed so as to extend in the left-right direction, and the length of the wide portion 128 in the left-right direction and the left-right direction of the filter portion 112. The length of the direction is the same. For this reason, the adhesive sent in the adhesive application head 10 can be rectified, and the pressure of the adhesive can be kept constant. Thereby, for example, as will be described later, when a plurality of adhesive discharge ports are formed in the adhesive application head, the discharge pressure of the adhesive from the plurality of adhesive discharge ports is made constant, and a plurality of bonding The amount of the adhesive discharged from the agent discharge port per unit time can be made uniform. Even if the numerical value of the horizontal length of the wide portion 128 and the numerical value of the horizontal length of the filter portion 112 are not the same, the difference between the length of the wide portion 128 and the length of the filter portion 112 is an error. If it is within the range, the length of the wide portion 128 and the length of the filter portion 112 are the same.
