The bumper 2 has a structure as shown in FIG. 4, and its details are as follows. A mounting plate 21 such as a plywood plate having a hole 21a to be mounted on the automatic guided vehicle 1, and a nut mounted to the hole 21a of the mounting plate. 22, a screw 23 screwed to the nut 22, and a base plate 24 made of rubber or the like that is adhesively fixed to the front surface side of the mounting plate 21 and has a hole 24a in the portion of the nut 22. The receiving plate 25 made of rubber or the like, which is located in the hole 24a of the base plate 24 and is moved back and forth by rotating the screw 23, is arranged so that one surface is in contact with the base plate 24 and the receiving plate 25. A pressure sensor 26, a pressing plate 27 made of soft rubber or the like arranged so as to cover the front surface of the pressure sensor 26, and a sponge 28 having a relatively large thickness arranged on the front surface side of the pressing plate 27. Cover the sponge 28, It is more structure and the cover film 29 of plastic or the like which is fixed to the urging plate 21.
【０００４】 前記した感圧センサ２６は、図５、図６に示す構成であり、その詳細は、一対 の硬質ゴムの板状体２６ａ，２６ｂの間にテープ状のスイッチ素子２６ｃを挟み こんだ構成である。一対の板状体２６ａ，２６ｂには、長手方向と直交する方向 に凹部２６ａ1 ，２６ｂ1 と、凸部２６ａ2 ，２６ｂ2 が交互に形成され、板状 体２６ａの凹部２６ａ1 に板状体２６ｂの凸部２６ｂ2 が、また、板状体２６ａ の凸部２６ａ2 が板状体２６ｂの凹部２６ｂ1 に互いに嵌まり込むものである。The above-described pressure-sensitive sensor 26 has a structure shown in FIGS. 5 and 6, and its details are such that a tape-shaped switch element 26c is sandwiched between a pair of hard rubber plate-shaped bodies 26a and 26b. It is a composition. A pair of plate-like body 26a, the 26b, the recess 26a 1, 26b 1 in the direction perpendicular to the longitudinal direction, the convex portions 26a 2, 26b 2 are formed alternately, the plate in the recess 26a 1 of the plate-like body 26a The convex portion 26b 2 of the body 26b and the convex portion 26a 2 of the plate-shaped body 26a 1 fit into the concave portion 26b 1 of the plate-shaped body 26b.
【０００５】 そして、各板状体２６ａの長手方向の中央には、前記スイッチ素子２６ｃが配 置される浅い溝２６ａ3 が形成されている。一方、スイッチ素子２６ｃは、一対 の対抗した電極２６ｃ1 ，２６ｃ2 と、該電極２６ｃ1 ，２６ｃ2 間を絶縁する 柔軟な絶縁材２６ｃ3 と、前記電極２６ｃ1 ，２６ｃ2 および絶縁材２６ｃ3 を 覆うビニール等の柔軟な被覆材２６ｃ4 とより構成されている。なお、前記被覆 材２６ｃ4 の一面長手方向には突条２６ｃ5 が形成されている。A shallow groove 26a 3 in which the switch element 26c is arranged is formed at the center in the longitudinal direction of each plate 26a. On the other hand, the switch element 26c includes an electrode 26c 1, 26c 2 which is a pair of opposing, with the electrodes 26c 1, 26c 2 between flexible insulating material 26c 3 for insulating, the electrode 26c 1, 26c 2 and the insulating material 26c 3 It is composed of a flexible covering material 26c 4 such as vinyl covering the above. A ridge 26c 5 is formed in the longitudinal direction of one surface of the covering material 26c 4 .
【０００６】 このように構成したスイッチ素子２６ｃを、前記板状体２６ａ，２６ｂに形成 した溝２６ａ3 に突状２６ｃ5 を上にして配置し、板状体２６ａ，２６ｂを一体 化する。そして、このスイッチ素子２６ｃをバンパ２に組み込んだ無人搬送車１ が走行中に器物に当接した場合の動作を以下に説明する。The switch element 26c configured in this manner is arranged in the groove 26a 3 formed in the plate-like bodies 26a and 26b with the protrusion 26c 5 facing upward, and the plate-like bodies 26a and 26b are integrated. Then, the operation when the automatic guided vehicle 1 having the switch element 26c incorporated in the bumper 2 comes into contact with an article during traveling will be described below.
【０００７】 バンパ２が器物に当接すると、当接力はビニールレザー２９、スポンジ２８お よび押圧板２７を介して感圧センサ２６に伝達される。この当接力が伝達される と、板状体２６ａを介してスイッチ素子２６ｃの突条２６ｃ5 を介して電極２６ ｃ2 を、電極２６ｃ1 側に押圧するので、該電極２６ｃ1 ，２６ｃ2 が接触して スイッチとしてオン状態となり、バンパ２が器物に当接したことを検出でき、こ の検出出力によって無人搬送車１を停止させることができる。When the bumper 2 comes into contact with the object, the contact force is transmitted to the pressure sensor 26 via the vinyl leather 29, the sponge 28 and the pressing plate 27. If the contact force is transmitted, the electrode 26 c 2 through the protrusions 26c 5 of the switching element 26c via a plate-like body 26a, so that pressing on the electrode 26c 1 side, the electrodes 26c 1, 26c 2 is Upon contact, the switch is turned on, and it can be detected that the bumper 2 has come into contact with an article, and the automatic guided vehicle 1 can be stopped by the detection output.
【０００８】 前記した感圧センサ２６において、器物が当接した時の感度を調節するには、 ネジ２３を回動して受け板２５を前後動させることにより、すなわち、ネジ２３ をねじ込むことにより、受け板２５が前進してスポンジ２８を圧縮することにな るので感度は高くなり、また、ネジ２３を緩めると感度は低くなり、感度調節が 行えるものである。In the pressure-sensitive sensor 26 described above, in order to adjust the sensitivity when an object contacts, the screw 23 is rotated to move the receiving plate 25 back and forth, that is, the screw 23 is screwed in. Since the receiving plate 25 moves forward to compress the sponge 28, the sensitivity becomes high, and when the screw 23 is loosened, the sensitivity becomes low and the sensitivity can be adjusted.
【０００９】[0009]
ところで、前記した感度調節において、感度を高めるためにネジ２３をナット ２２に対してねじ込んでゆくと、該ネジ２３は取付板２１の内側に入り込み、ね じ込み過ぎるとネジ２３はナット２２から外れて、バンパ２内に転がり込むこと となる。 By the way, in the above-mentioned sensitivity adjustment, when the screw 23 is screwed into the nut 22 in order to increase the sensitivity, the screw 23 enters the inside of the mounting plate 21, and if screwed too much, the screw 23 comes off from the nut 22. Then, it will roll into the bumper 2.
【００１０】 ネジ２３がバンパ１内、具体的には取付板２１と押圧板２５との間に転がり込 むと、感度調節が全く行えなくなると共に、ネジ２３が取付板２１と押圧板２５ との間に存在することから、このネジ２３が邪魔になり、新たなネジによって感 度調節を行う際に、転がり込んだネジ２３が邪魔になるといった問題があった。When the screw 23 rolls in the bumper 1, specifically, between the mounting plate 21 and the pressing plate 25, the sensitivity cannot be adjusted at all, and the screw 23 moves between the mounting plate 21 and the pressing plate 25. However, there is a problem in that the screw 23 that has fallen into the hindrance interferes with the screw 23 that has rolled in when the sensitivity is adjusted by a new screw.
【００１１】 本考案は前記した問題点を解決せんとするもので、その目的とするところは、 感度調節用のネジをねじ込んでも、一定量がねじ込まれるそれ以上のねじ込みが 阻止され、ネジがバンパ内に転がり込むことがないようにした物体の接触力検出 装置を提供せんとするにある。The present invention is intended to solve the above-mentioned problems, and it is an object of the present invention to prevent the screwing of a certain amount even if the screw for adjusting the sensitivity is screwed in, thereby preventing the screwing of the bumper. The purpose is to provide a device for detecting the contact force of an object that prevents it from rolling inside.
【００１２】[0012]
本考案の物体の接触力検出装置は前記した目的を達成せんとするもので、その 手段は、車両のバンパーに取付けられる取付板と、該取付板に嵌合固定されたナ ットに対して螺合されたネジと、該ネジの前記ナットに対する螺合度合いを調節 することによって前後動する受け板と、該受け板の前面に取付けられた柔軟な絶 縁材で絶縁された一対の電極を被覆材で包んだスイッチ素子と、該スイッチ素子 を前記受け板とで挟む押圧板と、該押圧板の前面に配置さたスポンジと、該スポ ンジおよび前記取付板を覆う覆い膜とからなる物体の接触力検出装置において、 前記ネジの先端をネジ部より小径の軸部となし、かつ、前記ナットに前記軸部が 嵌挿される小孔を形成したことを特徴とする。 The object contact force detecting device of the present invention is intended to achieve the above-mentioned object, and its means is to attach to a vehicle bumper and a nut fitted and fixed to the attaching plate. The screwed screw, the receiving plate that moves back and forth by adjusting the screwing degree of the screw with respect to the nut, and the pair of electrodes insulated by the flexible insulating material attached to the front surface of the receiving plate. Object consisting of a switch element wrapped in a covering material, a pressing plate sandwiching the switch element with the receiving plate, a sponge arranged in front of the pressing plate, and a covering film covering the sponge and the mounting plate. In the contact force detecting device, the tip of the screw is formed as a shaft portion having a diameter smaller than that of the screw portion, and a small hole into which the shaft portion is fitted is formed in the nut.
【００１３】 また、前記スイッチ素子は、硬質ゴム製による２枚の板状体の間に挟むことが 望ましく、さらに、前記２枚の板状体は互いに嵌まり会う凹部と凸部とが形成さ れると共に１枚の板状体には前記スイッチ素子が載置される長手方向に浅い溝が 形成され、かつ、前記スイッチ素子における前記被覆材の表面には突条が形成さ れ、この突条が前記浅い溝が形成されていな方の前記板状体に面した状態で挟み 込みこむかとが望ましい。Further, it is preferable that the switch element is sandwiched between two plate-shaped members made of hard rubber, and further, the two plate-shaped members are formed with a concave portion and a convex portion which are fitted to each other. At the same time, a shallow groove is formed in the longitudinal direction in which the switch element is mounted, and a ridge is formed on the surface of the covering material of the switch element. It is desirable to sandwich the plate-shaped body facing the plate-shaped body on which the shallow groove is not formed.
【００１４】[0014]
以下、本考案に係る物体の接触力検出装置の詳細を図１、図２と共に説明する 。なお、前記した従来例と同一符号は同一部材を示し、説明は省略する。 図において、３はネジ、４はナットであり、従来例のネジ２３、ナット２２に 対応する。 Hereinafter, details of the object contact force detecting apparatus according to the present invention will be described with reference to FIGS. The same reference numerals as those in the above-mentioned conventional example indicate the same members, and the description thereof will be omitted. In the figure, 3 is a screw and 4 is a nut, which correspond to the screw 23 and the nut 22 of the conventional example.
【００１５】 本考案の特徴とするところは、頭部がマイナスネジあるいは六角穴ネジであっ て、先端がネジ部３１の径より小径の軸部３２になっているネジ３であり、また 取付板２１の背面側から孔２１ａに挿入され、かつ、爪４１が取付板２１に食い 込んで固定されたナット４の先端に、前記ネジ部３１は通過しないが前記軸部３ ２が挿通される小孔４２を形成したことである。A feature of the present invention is that the head is a minus screw or a hexagon socket screw, and the tip is a screw 3 having a shaft portion 32 having a diameter smaller than the diameter of the screw portion 31, and the mounting plate. 21 is inserted into the hole 21a from the back side of the nut 21 and the tip of the nut 4 that is fixed by the claw 41 biting into the mounting plate 21 is fixed. That is, the holes 42 are formed.
【００１６】 このようにネジ３およびナット４を形成することにより、ネジ３をナット４に 螺合し前進させると、ネジ３の軸部３２がナット４の小孔４２から突出して、該 軸部３２の先端に位置する受け板２５を押圧し、その結果、スイッチ素子２６が 押圧板２７に向かって押し付けられ、該スイッチ素子２６の感度は高くなる。By thus forming the screw 3 and the nut 4, when the screw 3 is screwed into the nut 4 and moved forward, the shaft portion 32 of the screw 3 projects from the small hole 42 of the nut 4, and the shaft portion 32 The receiving plate 25 located at the tip of 32 is pressed, and as a result, the switch element 26 is pressed toward the pressing plate 27, and the sensitivity of the switch element 26 increases.
【００１７】 ところで、前記ネジ３をスイッチ素子２６の感度を高めるためにねじ込んでゆ くと、ネジ部３１の先端がナット４の小孔４２に当接して、それ以上の前進を阻 止することとなる。従って、従来のようにネジ３がナット４から外れて、取付板 ２１と受け板２５との間に落下することがなく、ネジ３を紛失したり、ネジ３が 受け板２５の前後動を妨げたりすることがない。By the way, when the screw 3 is screwed in to increase the sensitivity of the switch element 26, the tip of the screw portion 31 comes into contact with the small hole 42 of the nut 4 and prevents further advancement. Becomes Therefore, the screw 3 does not come off from the nut 4 and falls between the mounting plate 21 and the receiving plate 25 as in the conventional case, and the screw 3 is lost or the screw 3 prevents the receiving plate 25 from moving back and forth. There is nothing to do.
【００１８】 また、スイッチ素子２６は２枚の板状体２６ａ，２６ｂの間に挟まれた状態で 受け板２５と押圧板２７の間に位置するので、細長いテープ状のスイッチ素子２ ６が移動したりすることがなく、かつ、２枚の板状体２６ａ，２６ｂは互いに嵌 まり会う凸部２６ａ1 ，２６ｂ1 と凹部２６ａ1 ，２６ｂ2 とが形成されている ので、２枚の板状体２６ａ，２６ｂがずれるようなことがない。Further, since the switch element 26 is located between the receiving plate 25 and the pressing plate 27 while being sandwiched between the two plate-like bodies 26a and 26b, the elongated tape-shaped switch element 26 moves. Since the two plate-like bodies 26a and 26b are formed with the convex portions 26a 1 and 26b 1 and the concave portions 26a 1 and 26b 2 which are fitted to each other, The bodies 26a and 26b are not displaced.
【００１９】 さらに、スイッチ素子２６ｃに突条２６ｃ5 を形成したことにより、板状体２ ６ｂに加わる外圧が突状２６ｃ5 に伝達されるようになり、小さな外力が加わっ ても大きく変形し、従って、スイッチ素子２６ｃの感度が向上することとなる。Further, by forming the protrusions 26c 5 on the switch element 26c, the external pressure applied to the plate-like body 26b is transmitted to the protrusions 26c 5 , and even if a small external force is applied, it is greatly deformed. Therefore, the sensitivity of the switch element 26c is improved.
【００２０】[0020]
本考案は前記したように、スイッチ素子の感度を調節するためのネジの先端を ネジ部より小径の軸部となし、かつ、このネジが螺合されるナットに前記軸部が 嵌挿される小孔を形成したことにより、ネジをねじ込んでも該ネジのネジ部が小 孔に当接してそれ以上のねじ込みを阻止し、ネジが取付板と受け板との間に入り 込むことがなく、従って、ネジを紛失したり、ネジが受け板の前後動を妨げたり することがないものである。 As described above, according to the present invention, the tip of the screw for adjusting the sensitivity of the switch element is a shaft portion having a diameter smaller than that of the screw portion, and the shaft portion is fitted into a nut to which the screw is screwed. By forming the hole, even if the screw is screwed in, the threaded portion of the screw abuts the small hole to prevent further screwing, and the screw does not enter between the mounting plate and the receiving plate. The screws will not be lost and the screws will not interfere with the back-and-forth movement of the backing plate.
【００２１】 また、スイッチ素子は２枚の板状体の間に挟まれた状態で受け板と押圧板の間 に位置するので、細長いテープ状のスイッチ素子が移動したりすることがないと 共に、２枚の板状体は互いに嵌まり会う凸部と凹部とが形成されているので、２ 枚の板状体がずれるようなことがない外、スイッチ素子に突条を形成したことに より、板状体に加わる外圧が突状に伝達されるようになり、小さな外力が加わっ ても大きく変形し、従って、スイッチ素子の感度が向上する等の効果を有するも のである。Further, since the switch element is located between the receiving plate and the pressing plate in a state of being sandwiched between the two plate-like bodies, there is no possibility that the elongated tape-like switch element will move, and Since the two plate-shaped bodies are formed with the convex portions and the concave portions that are fitted to each other, the two plate-shaped bodies are not displaced, and the ridges are formed on the switch element. The external pressure applied to the cylindrical body is transmitted in a protruding manner, and even if a small external force is applied, it is greatly deformed, and therefore, the sensitivity of the switch element is improved.
