【従来の技術】
例えば、管廊の側壁に斜めに等間隔で多数取り付けられたランプのうち、故障したものや不良となったものを新しいランプと取り替えるのに人手で行っていた。然るに、このような場所は自由に作業するには狭く、また環境は余りよくない。従って、ロボットにより自動的に取替作業を行なうことが検討されている。
【0003】
【発明が解決しようとする課題】
本発明は上述の問題に鑑みてなされ、上述のような場所でも自動的に斜めに取り付けられているランプでも取り替えを行なうことができ、人手が不要な物品の着脱装置を提供することを課題とする。

【0005】
以上のような構成により、斜めに取り付けた物品を取り外す場合でも、あるいはこれを取り替える場合でも、確実に所定の位置から取り外し、また新しい物品を所定の位置に位置決めして、確実に該位置に取り付けることができる。人手は全く不要である。
【0006】
【発明の実施の形態】
図1は本発明の実施の形態のランプの着脱装置の全体を示すが、本着脱装置は全体として3で示され、例えば管廊内の支柱1に後述する部材を介して取り付けられたランプMを取り外すか、新しいランプMを該位置に取り付けるべく構成され、その全体は支柱1に対して垂直に固定された横材2に、紙面に対し垂直方向に移動自在に懸吊されている。
【0007】
すなわち、各種の駆動機構を内蔵する本体4の両側壁部には前後で各一対の垂直懸吊アーム5a、5bが固定されており、これらの上端部には転動自在に車輪6a、6bが支承されている。
【0008】
横材2にはガイドレール7が固定されており、その断面形状はI形状であるが、その下側の軌条部7aに上述の車輪6a、6bが転動自在に圧接している。また本体4の両側壁部に横方向に延びる副懸吊用アーム8a、8bが固定されており、この上端部にはローラ10a、10bが回転自在に取り付けられていて、横材2に固定された断面L字形状の副レール9に転動自在に圧接している。
【0009】
前後方向に延びる水平な支軸11には、これに対し回動可能に一対の係合アーム12a、12bが取り付けられ、更にこれらにそれぞれコ字形状の検出部材13a、13bが取り付けられていて、その上下の水平アーム部には相対向して検出素子としての発光素子14a、14b及び被検出素子としての受光素子15a、15bが取り付けられている。支柱1には斜めになった取付フレーム20が固定されており、これに電力供給装置21が取り付けられている。図2に明示されるように電力供給装置21の中央部には電力供給挿込口22が形成され、この両側に一対の取付ピン23a、23bが立設している。これら取付ピン23a、23bはそれぞれ下から基部A、大径部B、中径部C、テーパ部D及び小径部Eから成っており、大径部Bには平面的形状がT字形状の遮蔽板19a、19bが取り付けられている。これらは両側に延びる水平アーム部Ga、Gb及びこれらの中央部に垂直方向に形成される突出アーム部Fから成っている。なお、以後の説明の便宜上、他方の対応部分にはGa ’、Gb’及びF として符示する。
【0010】
取付ピン23a、23bを介して電力供給装置21に取り付けられるべき物品は本実施の形態ではランプもしくは灯具Mであり、その下面にプラグ35を形成させており、取付状態では、電力供給挿込口22に挿込まれている。灯具Mの両側壁部には外方に向かって突出するタブ30a、30bが一体的に形成され、これらには取付ピン23a、23bの小径部E、テーパ部D及び中径部Cを挿通させる円形開口31a、31bが形成されており、中径部Cはこれに密嵌する径となっている。
【0011】
本体4はコ字形状の検出部材13a、13bを支軸11のまわりに回動させるための第1駆動装置、係合レバー12a、12bを独立して相接近する方向及び相遠去かる方向に駆動するための第2駆動装置及び係合レバー12a、12bを上下動させるための第3駆動装置を内蔵している。係合レバー12a、12bの内壁には一対の係合ピン40a、40a、40b、40bが取り付けられており、これらは大径部H、テーパ部I及び小径部Jから成っている。また灯具Mのタブ30a、30bの側壁部には上記係合ピン40a、40a、40b、40bを挿入させる一対の孔42a、42a’及び42b、42b’を形成させている。係合ピン40a、40a、40b、40bの大径部Fは孔42a、42a’、42b、42b’に密嵌する大きさの径となっている。なお、以上の係合レバー12a、12b及び検出部材13a、13bにより検出・係合装置が構成される。
【0012】
本発明の実施の形態は以上のように構成されるが、次にこの作用について説明する。
【0013】
本実施の形態においては、管廊において支柱1には等間隔で多数の灯具Mが取り付けられている。ランプ着脱装置3はガイドレール7に沿って紙面(図1)に対し垂直方向に移動可能であり、図示せずとも各灯具の取付位置を検出する手段を備えているものとする。今、管廊の入口から数えて50個めの灯具Mが不良となったので取り替える場合について説明する。
【0014】
着脱装置3は入口からカウントして行き、例えば、50個めで取り替えるべき灯具Mの前に停止する。まず第1駆動装置の駆動により、図2に明示されるように係合レバー12a、12bが矢印Nで示す方向に、支軸11のまわりに所定角度回動する。これにより、図5に示すように実線の位置から一点鎖線の位置に回動するのであるが、取付ピン23a、23bには平面的形状がT字形状の遮蔽板19a、19bが取り付けられている。一方、係合レバー12a、12bは、やはり本体4が内蔵する第2駆動装置により最も相遠ざかった位置にあり、この状態から第1駆動装置により一点鎖線で示す位置に回動するのであるが、検出部材13a、13bに取り付けられている第1、第2検出素子としてのランプ14a、14bは初期位置においては、これらが対向する第1、第2被検出素子としての受光素子15a、15bを投光しており、これらはオンの状態にある。第1駆動装置の駆動により、図3の一点鎖線で示すような各位置に所定角度回動すると、図5に明示されるように遮蔽板19a、19bの外側水平アーム部Gb、Gb’により第1検出素子14a、14aからの光はこれにより遮光されて、対向する第1被検出素子としての受光素子15a、15aには投光されなくなり、所定角度回動したことを検出する。
【0015】
次に、第3駆動装置の駆動で所定距離、係合レバー12a、12bは図3で実線で示す位置に下降する。次いで、第2駆動装置(2つの駆動部から成る)の駆動により係合レバー12a、12bは相接近する方向に独立して駆動される。図6に実線で示す位置に至ると、第2検出素子としての発光素子14b、14bからの光線は遮蔽板19a、19bの垂直アーム部F、F’により遮光される。これにより係合レバー12a、12bが停止するのであるが、この状態では第1、第2発光素子14a、14bとも、その光線は遮蔽板19a、19bにより遮光され、第1、第2受光素子15a、15bはいずれもオフとなっている。灯具Mに対しセンタリングされたことになる。係合ピン40a、40a、40b、40bの小径部Jが灯具Mの両側壁部に一体的に形成されたタブ30a、30bの側壁部に形成した孔に挿通される。次いで、第3駆動装置の駆動により係合レバー12a、12bを所定距離だけ上昇させる。この移動距離は、図6に示すように、第1、第2受光素子15a、15bが遮光された後、第2駆動装置の駆動開始と共に駆動モータのパルス数をカウントして所定値に達すると、停止させて決定するようにしても良い。
【0016】
上述の上昇をさせるべく第3駆動装置の駆動モータを所定パルス数になるまで駆動すると、タブ30a、30bに形成した貫通孔31a、31bに遊合状態であるので、この係合レバー12a、12bの上昇中に、なお先端の位置決めが不正確であれば、取り付けピン23a、23bに対する自動調心が行われる。係合ピン40a、40a、40b、40bの小径部Jの孔42a、42a’、42b42b’に対するクリアランスは図示するように充分に大きいので、このような自動調心が可能となる。更に、第2駆動装置の駆動により、係合ピン40a、40a、40b、40bの相近接する方向への移動により、図7の実線で示すように、係合ピン40a、40a、40b、40bは孔に対し密嵌状態となる。なお、図6から図7までの係合ピン40a、40a、40b、40bの移動は上述したように第2駆動装置の駆動モータで行われるが、この停止点は図示せずともランプMのタブ30a、30bの側壁部に取り付けられた近接スイッチにより、係合ピン40a、40bを固定させている係合レバー12a、12bが検知されることにより決められる。この後、灯具Mは上昇させられるが、この時には、既にこの灯具Mのタブ30a、30bに形成した孔23a、23bに対して両係合ピン12a、12bは正確に位置決めされた状態で上昇させるので、円滑に取付ピン23a、23bから灯具Mを抜き去ることができる。すなわち、図3で示す上昇位置にもたらされるが、この後、図2とは逆方向に第1駆動装置により回動される。すなわち、図5において一点鎖線で示す位置から実線で示す位置へと回動する。これにより不良品の灯具Mは完全にその取付位置から取り外されたことになる。
【0017】
次に、新しい灯具M’を、古いランプが取り除かれた電力供給装置21に取り付ける場合について説明する。この場合には、本体4内で既に新しい灯具M’を係合レバー12a、12bの内側壁に固定させた係合ピン40a、40a、40b、40bが圧入されて固持されており、この状態で第1駆動装置の駆動により支軸11のまわりに所定角度回動する。図8において一点鎖線で示す位置に回動し、遮蔽板19a、19bの垂直アーム部F及び内側水平アーム部Ga’により第1の発光素子14a、14aの光線が遮光されることによって所定角度回動していることを検知する。次いで、第3駆動装置により所定距離灯具Mを降下させる。この後、第2駆動装置の駆動により係合レバー12a、12bを同時に、図9において左方へと移動させる。第1、第2受光素子15a、15bは共に垂直アーム部F、F’の内縁部により遮光される。これにより、センター位置に位置決めされたことを検知し、この後、係合レバー12a、12bを相遠去かる方向に所定距離、第2駆動装置により駆動する。この場合にも、第1、第2受光素子15a、15bが遮光された位置(図9の実線で示す)を検知した直後に、パルスモータの駆動により所定パルス数を駆動して、図10の実線で示す位置をとらせる。すなわち、係合ピン40a、40bの小径部Jが灯具M’のタブ30a、30bの孔42a、42a’、42b、42b’内で第2駆動装置により外方へと移動させられると、係合ピン40a、40bの小径部Jとタブ30a、30bの両側壁に形成した孔42a、42a’、42b、42b’との遊合度により灯具M’は取付ピン23a、23bに対する自動調心が行われながら自然落下し、灯具M’の孔31a、31bは確実に取付ピン23a、23bの中径部Cに嵌入される。よって、新しいランプM’が、確実にかつ正確に電力供給装置22にそのプラグ35を嵌入させて取り付けられる。この後、係合レバー12a、12bは更に相遠去かる方向に(図10で一点鎖線で示す位置)へと同時に第2駆動装置により駆動され、この後、第1駆動装置により図2の矢印Nとは所定角度逆方向に駆動される。
【0018】
本発明の実施の形態は上記のように構成され、かつ作用を行なうので、限られた空間内にあって斜めに灯具が取り付けられていても、あるいは取り付ける場合でも、灯具交換装置3により、自動的に、かつ正確に電力供給装置21に取り付けることができ、また不良となった灯具Mを電力供給装置21から取り外すことができる。
【0019】
以上、本発明の実施の形態について説明したが、勿論、本発明はこれに限られることなく、本発明の技術的思想に基づいて種々の変形が可能である。
【0020】
例えば以上の実施の形態では、管廊における灯具の交換に適用されたが、これに限られることなく、如何なる位置に対しても自動的に正確に位置決めして新しい物品を取り付けることができ、また不良となった物品をこの所定の位置から取り外すことができる。
【0021】
また以上の実施例では、取り付け部材として一対の立設するピン23a、23bを説明したが、勿論、形状や種類はこれに限定されることなく、例えば電磁石の吸着側を取り付け部材とし、物品Mの被取付部を吸着される側の部材としてもよい。
【0022】
また以上の実施例では、係合ピン40a、40bを灯具Mの両側壁部に形成したタブ30a、30bの側壁部に形成した孔42a、42bに嵌入することにより係合状態としたが、係合ピンの代わりに真空パッドのような吸着パッドを用い、この物品の両側壁面を吸着させるようにしてもよい。第1、第2駆動装置は、これら被取付部材あるいは被係合部の形状や種類によって適宜変更してもよい。
【0023】
【発明の効果】
以上述べたように、本発明の物品の着脱装置によれば、斜めとなった取付状態でも自動的に不良品と良品との交換を正確に位置決めして行なうことができる。

The above-described engagement levers 12a and 12b and the detection members 13a and 13b constitute a detection / engagement device.
[0012]
The embodiment of the present invention is configured as described above. Next, this operation will be described.
[0013]
In the present embodiment, a number of lamps M are attached to the column 1 at regular intervals in the duct. The lamp attaching / detaching device 3 is movable along the guide rail 7 in the direction perpendicular to the paper surface (FIG. 1), and includes means for detecting the mounting position of each lamp, not shown. Now, the case where the 50th lamp M counted from the entrance of the duct has become defective will be described.
[0014]
The detachable device 3 counts from the entrance, and stops before the lamp M to be replaced, for example, at the 50th. First, as shown in FIG. 2, the engagement levers 12 a and 12 b are rotated by a predetermined angle around the support shaft 11 in the direction indicated by the arrow N by driving the first drive device. Thereby, as shown in FIG. 5, it rotates from the position of the solid line to the position of the alternate long and short dash line, but the shielding pins 19 a and 19 b having a T-shaped planar shape are attached to the attachment pins 23 a and 23 b. . On the other hand, the engagement levers 12a and 12b are at positions farthest away from each other by the second driving device built in the main body 4. From this state, the first driving device rotates to the position indicated by the alternate long and short dash line. In the initial position, the lamps 14a and 14b as the first and second detection elements attached to the detection members 13a and 13b project the light receiving elements 15a and 15b as the first and second detection elements facing each other. They are lit and they are on. When the first driving device is driven to rotate to predetermined positions as shown by the one-dot chain line in FIG. 3 by the driving of the first driving device, the outer horizontal arm portions Gb and Gb ′ of the shielding plates 19a and 19b The light from the first detection elements 14a and 14a is blocked by this, and is not projected to the light receiving elements 15a and 15a as the first detected elements facing each other, and it is detected that the light has rotated a predetermined angle.
[0015]
Next, when the third driving device is driven, the engagement levers 12a and 12b are lowered to a position indicated by a solid line in FIG. Next, the engagement levers 12a and 12b are independently driven in the direction in which they approach each other by the driving of the second driving device (comprising two driving units). When the position shown by the solid line in FIG. 6 is reached, light rays from the light emitting elements 14b and 14b as the second detection elements are shielded by the vertical arm portions F and F ′ of the shielding plates 19a and 19b. As a result, the engaging levers 12a and 12b are stopped. In this state, the light beams of both the first and second light emitting elements 14a and 14b are blocked by the shielding plates 19a and 19b, and the first and second light receiving elements 15a. , 15b are both off. That is, the lamp M is centered. The small-diameter portions J of the engaging pins 40a, 40a, 40b, and 40b are inserted through holes formed in the side walls of the tabs 30a and 30b that are integrally formed on both side walls of the lamp M. Next, the engagement levers 12a and 12b are raised by a predetermined distance by driving the third driving device. As shown in FIG. 6, when the first and second light receiving elements 15a and 15b are shielded from light, the moving distance reaches the predetermined value by counting the number of pulses of the driving motor as the second driving device starts driving. Alternatively, it may be determined after stopping.
[0016]
When the drive motor of the third drive device is driven to the predetermined number of pulses to raise the above-mentioned, the engagement levers 12a and 12b are engaged with the through holes 31a and 31b formed in the tabs 30a and 30b. If the positioning of the tip is still inaccurate during the ascent of the motor, the mounting pins 23a and 23b are automatically aligned. Since the clearances with respect to the holes 42a, 42a ′, 42b42b ′ of the small diameter portion J of the engaging pins 40a, 40a, 40b, 40b are sufficiently large as shown in the figure, such automatic alignment is possible. Further, when the second driving device is driven, the engaging pins 40a, 40a, 40b, and 40b move in the directions close to each other, so that the engaging pins 40a, 40a, 40b, and 40b become holes as shown by the solid lines in FIG. It will be in a close fitting state. The movement of the engaging pins 40a, 40a, 40b, 40b from FIG. 6 to FIG. 7 is performed by the drive motor of the second drive device as described above. This is determined by detecting the engagement levers 12a and 12b fixing the engagement pins 40a and 40b by proximity switches attached to the side walls of 30a and 30b. Thereafter, the lamp M is raised, but at this time, both the engaging pins 12a and 12b are raised with the holes 23a and 23b already formed in the tabs 30a and 30b of the lamp M being accurately positioned. Therefore, the lamp M can be smoothly removed from the mounting pins 23a and 23b. That is, although it is brought to the raised position shown in FIG. 3, it is rotated by the first drive device in the direction opposite to that shown in FIG. That is, it rotates from the position shown by the one-dot chain line in FIG. 5 to the position shown by the solid line. As a result, the defective lamp M is completely removed from the mounting position.
[0017]
Next, a case where a new lamp M ′ is attached to the power supply device 21 from which the old lamp has been removed will be described. In this case, the engagement pins 40a, 40a, 40b, 40b in which the new lamp M ′ is already fixed to the inner walls of the engagement levers 12a, 12b are press-fitted and held in the main body 4. The first drive device is rotated around the support shaft 11 by a predetermined angle. 8 is rotated to a position indicated by a one-dot chain line, and the light beams of the first light emitting elements 14a and 14a are shielded by the vertical arm portion F and the inner horizontal arm portion Ga ′ of the shielding plates 19a and 19b. Detect that it is moving. Next, the predetermined distance lamp M is lowered by the third driving device. Thereafter, the engagement levers 12a and 12b are simultaneously moved leftward in FIG. 9 by driving the second drive device. Both the first and second light receiving elements 15a and 15b are shielded from light by the inner edge portions of the vertical arm portions F and F ′. Thereby, it is detected that it is positioned at the center position, and thereafter, the engagement levers 12a and 12b are driven by the second driving device for a predetermined distance in a direction away from each other. Also in this case, immediately after detecting the position where the first and second light receiving elements 15a and 15b are shielded from light (shown by the solid line in FIG. 9), a predetermined number of pulses are driven by the driving of the pulse motor. Take the position indicated by the solid line. That is, when the small-diameter portion J of the engaging pins 40a and 40b is moved outward by the second driving device in the holes 42a, 42a ′, 42b and 42b ′ of the tabs 30a and 30b of the lamp M ′, The lamp M ′ is automatically aligned with respect to the mounting pins 23a and 23b by the degree of play between the small diameter portion J of the pins 40a and 40b and the holes 42a, 42a ′, 42b and 42b ′ formed on both side walls of the tabs 30a and 30b. While falling naturally, the holes 31a and 31b of the lamp M 'are securely inserted into the medium diameter portions C of the mounting pins 23a and 23b. Therefore, the new lamp M ′ is attached with the plug 35 inserted into the power supply device 22 reliably and accurately. Thereafter, the engaging levers 12a and 12b are driven by the second driving device at the same time in the direction away from each other (the position indicated by the alternate long and short dash line in FIG. 10), and thereafter, the arrows shown in FIG. Driven in a direction opposite to N by a predetermined angle.
