以下、図面を参照しつつ本発明の一実施形態について説明する。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

本発明の実施形態に係る全方向移動台車は、第1の平板と第2の平板とが通常状態時(基本姿勢時とも言う)に同一平面上にあり、第1の平板に対して第2の平板が回動自在となるように両者が軸部材により連結されている。第2の平板は、第1の平板に対して、軸部材の周方向に回動自在となっている。後述するが、第1の平板には、2つの駆動部が配設されており、第2の平板にも、2つの駆動部が配設されている。   In the omnidirectional mobile trolley according to the embodiment of the present invention, the first flat plate and the second flat plate are on the same plane in a normal state (also referred to as a basic posture), and the second flat plate is in a second position with respect to the first flat plate. Are connected by a shaft member so that the flat plate can be freely rotated. The second flat plate is rotatable relative to the first flat plate in the circumferential direction of the shaft member. As will be described later, two driving units are provided on the first flat plate, and two driving units are also provided on the second flat plate.

第1の平板と第2の平板は、上記関係にあるので、各駆動部に接続される車輪の接地面に高さ方向の変動、つまり凹凸等があり、少なくとも1つの車輪が凸部に乗り上げた場合であっても、第1の平板に対する第2の平板の軸部材周りの回動により、直進安定性が維持される。また、第1の平板の上に、第3の平板が実装される場合、その上に置かれた搭載物の平衡状態を維持することもできる。以下、構成及び作用を詳述する。   Since the first flat plate and the second flat plate have the above-mentioned relationship, there is a variation in the height direction on the grounding surface of the wheel connected to each drive unit, that is, unevenness, and at least one wheel rides on the convex portion. Even in this case, the straight running stability is maintained by the rotation of the second flat plate around the shaft member with respect to the first flat plate. Further, when the third flat plate is mounted on the first flat plate, the equilibrium state of the mounted object placed thereon can be maintained. Hereinafter, the configuration and operation will be described in detail.

ここで、軸継手部材4a乃至4dとは、カップリングとも称されるもので、モータ3a乃至3dとの駆動軸(シャフト)と従動軸(車軸部材6a乃至6d)とを繋ぎ、動力を伝達する機械要素部品であり、所定のたわみ性を持たせることで、両軸間の芯ずれを許容し、偏摩耗や振動等を解消するものである。   Here, the shaft coupling members 4a to 4d are also called couplings, and connect the drive shafts (shafts) of the motors 3a to 3d with the driven shafts (axle members 6a to 6d) to transmit power. It is a mechanical element part, which has a predetermined flexibility to allow for misalignment between both shafts and eliminate uneven wear and vibration.

In this example, the support member 12 has a shape in which screw grooves are formed at upper and lower ends, one end is fixed by a fixing member 19 on the plane of the third flat plate 10, and the other end is the first It is screwed into the screw groove of the flat plate 2A. In this example, the third flat plate 10 is disposed on the first flat plate 2A by eight support members 12. The third flat plate 10 has a shape that covers all of the first flat plate 2A, the second flat plate 2B, and the wheel cover members 11a to 11d. The strength of the third flat plate 10 may be increased by forming the third flat plate 10 into a U-shaped cross section whose end portion extends downward or upward by a predetermined length.

Can be adjusted. More specifically, the length of the regulating members 16a, 16b extending downward from the back surface of the third flat plate 10 can be adjusted by screwing nuts or the like as the positioning members 17a, 17b.

同様に、第3の平板10の、ホイルカバー部材11dの上部に位置する領域には、規制部材16c,16dが配設されており、各規制部材16c,16dは、位置決め部材17c,17dにより、その規制レベルが調整できるようになっている。より詳細には、規制部材16c,16dは、位置決め部材17c,17dとしてのナット等の螺合により、第3の平板10の背面より下方に延出する長さが調整できるようになっている。   Similarly, regulating members 16c and 16d are provided in a region of the third flat plate 10 located above the wheel cover member 11d, and the regulating members 16c and 16d are fixed by positioning members 17c and 17d. The regulation level can be adjusted. More specifically, the length of the regulating members 16c and 16d extending downward from the back surface of the third flat plate 10 can be adjusted by screwing nuts or the like as the positioning members 17c and 17d.

これら規制部材16a乃至16dは、第2の平板2Bに接続されるホイルカバー部材11c,11dの第3の平板10に対する高さ方向の変動を規制する役割を担っている。例えば、オム二ホイール5a乃至5dのいずれかが、接地面上の凸部に乗り上げ若しくは凹部に乗り下げ、第1の平板2Aに対する第2の平板2Bの傾きが変動する場合でも、その変動範囲を、この規制部材16a乃至16dの設定により規制することができる。   These restricting members 16a to 16d play a role of restricting the height change of the wheel cover members 11c and 11d connected to the second flat plate 2B with respect to the third flat plate 10. For example, even if any of the omni wheels 5a to 5d rides on a convex portion on the ground contact surface or rides down on a concave portion, and the inclination of the second flat plate 2B with respect to the first flat plate 2A fluctuates, the fluctuation range is not changed. It can be regulated by setting the regulating members 16a to 16d.

規制部材16a乃至16dは、ボルト等の鋼鉄部材のほか、消音目的からゴム等の弾性部材で実現するようにしてもよい。また、規制部材16a乃至16dの少なくとも一部の構成に、消音目的からシリコンなどの樹脂を採用してもよい。これらは、あくまでも消音目的で設けられたものであり、サスペンション機構における緩衝目的で設けられたものではない。   The restricting members 16a to 16d may be realized by an elastic member such as rubber for noise reduction purpose, in addition to a steel member such as a bolt. In addition, a resin such as silicon may be used for at least a part of the configuration of the regulating members 16a to 16d for the purpose of silencing. These are provided only for the purpose of silencing, and are not provided for the purpose of buffering the suspension mechanism.

ここで、オム二ホイール5a乃至5dの構成例を詳細に説明すると、各オム二ホイール5a乃至5dは、この例では、オムニフレームの支持脚間に配設されたバレル支持軸にバレルを回転可能に軸支した構成となっている。各オム二ホイール5a乃至5dは、このような構成により、モータ3a乃至3dの軸周りの回転のほか、バレル支持軸周りのバレルの回転も可能であることから、全方向への移動が実現される。尚、オム二ホイールの構成は、前述したものに限定されないことは勿論である。   Here, the configuration examples of the omni wheels 5a to 5d will be described in detail. In this example, each of the omni wheels 5a to 5d can rotate the barrel on a barrel support shaft disposed between the support legs of the omni frame. It is configured to be pivotally supported. Each of the omni-wheels 5a to 5d is capable of rotating the barrel around the barrel support axis in addition to the rotation around the axis of the motors 3a to 3d by such a configuration. You. Note that the configuration of the omni-wheel is not limited to the above.

以上の構成において、オム二ホイール5a乃至5dの接地面に高さ方向の変動、つまり凹凸が存在すると、オム二ホイール5a乃至5dが凸部を乗り上げ、或いは凹部に落ち込み、その結果、第1の平板2Aに対して第2の平板2Bが軸部材14周りに時計回り/反時計回りに回転し、第1の平板2Aに対して第2の平板2Bが所定の傾きを持つことになる。このような作用により、全方向移動台車1は、接地面に凹凸等が存在する場合であっても、第3の平板10上に置かれた搭載物の平衡状態を保ちながら、全方向への直進安定性を維持することができる。尚、本全方向移動台車1を自走式ロボット等に適用する場合、充電ステーションへの接続端子は、第1の平板2Aの第1の領域の第2の領域との分岐点等に設けることが可能である。   In the above configuration, if the ground surface of the omni wheels 5a to 5d fluctuates in the height direction, that is, if there are irregularities, the omni wheels 5a to 5d ride on the convex portions or fall into the concave portions, and as a result, the first The second flat plate 2B rotates clockwise / counterclockwise around the shaft member 14 with respect to the flat plate 2A, and the second flat plate 2B has a predetermined inclination with respect to the first flat plate 2A. By such an operation, the omni-directional mobile trolley 1 can maintain the equilibrium state of the load placed on the third flat plate 10 while maintaining the equilibrium state of the load placed on the third flat plate 10 even when the grounding surface has irregularities or the like. Straight running stability can be maintained. When the omnidirectional mobile trolley 1 is applied to a self-propelled robot or the like, a connection terminal to the charging station is provided at a junction of the first area of the first flat plate 2A with the second area. Is possible.

ここで、図6(a)及び図6(b)の概念図を参照して、本発明の一実施形態に係る全方向移動台車が、移動方向に応じて各オム二ホイール5a乃至5dの接地面の高さ方向の変動をいかに吸収するかを詳細に説明する。   Here, with reference to the conceptual diagrams of FIGS. 6A and 6B, the omnidirectional mobile trolley according to one embodiment of the present invention connects the omni-wheels 5a to 5d according to the moving direction. How to absorb the fluctuation in the height direction of the ground will be described in detail.

図6(a)に示されるように、第1の平板2Aのオム二ホイール5a,5b、第2の平板2Bのオム二ホイール5c,5dが、図6(a)中、矢印の方向に移動するように回転すると、全方向移動台車1は、前方(図中、太い矢印)に移動する。移動中に、オム二ホイール5c又は5dが接地面の凸部に乗り上げると、第2の平板2Bが、第1の平板2Aに対して、軸部材14周りに回転し、第2の平板2Bは、第1の平板2Aに対して所定の傾きを持つことになる。また、移動中に、オム二ホイール5a又は5bが接地面の凸部に乗り上げた場合も、第2の平板2Bが、第1の平板2Aに対して、軸部材14周りに回転したのと同じ状態になるので、第2の平板2Bは、第1の平板2Aに対して所定の傾きを持つ。このような作用により、直進安定性は維持される。   As shown in FIG. 6A, the omni wheels 5a and 5b of the first flat plate 2A and the omni wheels 5c and 5d of the second flat plate 2B move in the directions of arrows in FIG. 6A. Then, the omnidirectional mobile trolley 1 moves forward (thick arrow in the figure). When the omni wheel 5c or 5d rides on the convex portion of the ground contact surface during the movement, the second flat plate 2B rotates around the shaft member 14 with respect to the first flat plate 2A, and the second flat plate 2B Has a predetermined inclination with respect to the first flat plate 2A. Also, when the omni-wheel 5a or 5b rides on the convex portion of the ground contact surface during the movement, the second flat plate 2B rotates around the shaft member 14 with respect to the first flat plate 2A. In this state, the second flat plate 2B has a predetermined inclination with respect to the first flat plate 2A. By such an operation, straight running stability is maintained.

図6(b)に示されるように、第1の平板2Aのオム二ホイール5a,5b、第2の平板2Bのオム二ホイール5c,5dが、図6(b)中、矢印の方向に移動するように回転すると、全方向移動台車1は、左斜め前方(図中、太い矢印)に移動する。移動中に、オム二ホイール5c又は5dが接地面の凸部に乗り上げると、第2の平板2Bが、第1の平板2Aに対して、軸部材14周りに回転し、第2の平板2Bは、第1の平板2Aに対して所定の傾きを持つことになる。また、移動中に、オム二ホイール5a又は5bが接地面の凸部に乗り上げると、第2の平板2Bが、第1の平板2Aに対して、軸部材14周りに回転したのと同じ状態になるので、第2の平板2Bは、第1の平板2Aに対して所定の傾きを持つ。このような作用により、直進安定性は維持される。   As shown in FIG. 6B, the omni wheels 5a and 5b of the first flat plate 2A and the omni wheels 5c and 5d of the second flat plate 2B move in the directions of arrows in FIG. 6B. Then, the omnidirectional mobile trolley 1 moves diagonally to the left front (the thick arrow in the figure). When the omni wheel 5c or 5d rides on the convex portion of the ground contact surface during the movement, the second flat plate 2B rotates around the shaft member 14 with respect to the first flat plate 2A, and the second flat plate 2B Has a predetermined inclination with respect to the first flat plate 2A. Also, when the omni-wheel 5a or 5b rides on the convex portion of the ground contact surface during the movement, the second flat plate 2B is brought into the same state as rotated around the shaft member 14 with respect to the first flat plate 2A. Therefore, the second flat plate 2B has a predetermined inclination with respect to the first flat plate 2A. By such an operation, straight running stability is maintained.

次に、図7乃至図9を参照して、本発明の一実施形態に係る全方向移動台車による接地面の凹凸による影響を軽減する作用について詳細に説明する。以下の説明では、第3の平板10とホイルカバー部材11dとの隙間の間隔をd1、第3の平板10とホイルカバー部材11cとの隙間の間隔をd2と称する。   Next, with reference to FIG. 7 to FIG. 9, the operation of the omnidirectional mobile trolley according to the embodiment of the present invention for reducing the influence of the unevenness of the ground contact surface will be described in detail. In the following description, the gap between the third flat plate 10 and the wheel cover member 11c is referred to as d1, and the gap between the third flat plate 10 and the wheel cover member 11c is referred to as d2.

図7は、オム二ホイール5a乃至5dの接地面に高さ方向の変動、つまり凹凸がない場合の移動姿勢を示している。この場合には、全てのオム二ホイール5a乃至5dは平坦な同一平面上を移動するので、第2の平板2Bは、第1の平板2Aに対して軸部材14周りに回転することもなく、第1の平板2Aと第2の平板2Bは平行、換言すれば、同一平面上に位置付けされる。   FIG. 7 shows the movement posture in the case where there is no variation in the height direction on the ground contact surfaces of the omni wheels 5a to 5d, that is, when there is no unevenness. In this case, all the omni wheels 5a to 5d move on the same flat plane, so that the second flat plate 2B does not rotate around the shaft member 14 with respect to the first flat plate 2A. The first flat plate 2A and the second flat plate 2B are positioned in parallel, in other words, positioned on the same plane.

図8は、オム二ホイール5cの接地面に凸部が存在し、オム二ホイール5cが当該凸部を乗り上げた場合の移動姿勢を示している。この場合には、オム二ホイール5cが凸部に乗り上げるので、第2の平板2Bは、第1の平板2Aに対して軸部材14を中心に半時計回りに回転し、第1の平板2Aの平面に対して第2の平板2Bの平面は所定の傾きを持つことになる。この回転に伴い、ホイルカバー部材11cは、第3の平板10に近接する方向に変動することになるが、変動可能範囲については、規制部材16a,16bにより予め設定することが可能である。このような変動により、第3の平板10とホイルカバー部材11cとの隙間の間隔d2は、図7に示す通常走行時の間隔よりも短くなる。それに伴って、第3の平板10とホイルカバー部材11dとの隙間の間隔d1は、図7に示す通常走行時の間隔よりも長くなる。このように、全方向移動台車1は、第2の平板2Bの第1の平板2Aに対する軸部材14周りの回転により、第3の平板10の上に置かれた搭載物の平衡状態を保ちながら、直進安定性を維持することができる。更に、上記変動下であっても、4輪のオム二ホイール5a乃至5dのうちの少なくとも3輪が接地面に接触しているので、安定性も高い。   FIG. 8 shows a moving posture when a convex portion exists on the ground contact surface of the omni-wheel 5c and the omni-wheel 5c runs over the convex portion. In this case, since the omni-wheel 5c rides on the convex portion, the second flat plate 2B rotates counterclockwise around the shaft member 14 with respect to the first flat plate 2A, and the second flat plate 2B The plane of the second flat plate 2B has a predetermined inclination with respect to the plane. With this rotation, the wheel cover member 11c moves in the direction approaching the third flat plate 10, but the range in which the wheel cover member 11c can be moved can be preset by the regulating members 16a and 16b. Due to such a variation, the gap d2 between the third flat plate 10 and the wheel cover member 11c becomes shorter than the gap during normal running shown in FIG. Accordingly, the gap d1 between the third flat plate 10 and the wheel cover member 11d becomes longer than the gap during normal running shown in FIG. As described above, the omnidirectional mobile trolley 1 maintains the equilibrium state of the load placed on the third flat plate 10 by the rotation of the second flat plate 2B around the shaft member 14 with respect to the first flat plate 2A. , Straight running stability can be maintained. Further, even under the above fluctuation, at least three of the four omni-wheels 5a to 5d are in contact with the ground contact surface, so that the stability is high.

図9は、オム二ホイール5dの接地面に凸部が存在し、オム二ホイール5dが当該凸部を乗り上げた場合の移動姿勢を示している。この場合には、オム二ホイール5dが凸部に乗り上げるので、第2の平板2Bは、第1の平板2Aに対して軸部材14を中心に時計回りに回転し、第1の平板2Aの平面に対して第2の平板2Bの平面は所定の傾きを持つことになる。この回転に伴い、ホイルカバー部材11dは、第3の平板10に近接する方向に変動することになるが、変動可能範囲については、規制部材16c,16dにより予め設定することが可能である。このような変動により、第3の平板10とホイルカバー部材11dとの隙間の間隔d1は、図7に示す通常走行時の間隔よりも短くなる。それに伴って、第3の平板10とホイルカバー部材11cとの隙間の間隔d2は、図7に示す通常走行時の間隔よりも長くなる。このように、全方向移動台車1は、第2の平板2Bの第1の平板2Aに対する軸部材14周りの回転により、第3の平板10の上に置かれた搭載物の平衡状態を保ちながら、直進安定性を維持することができる。更に、上記変動下であっても、4輪のオム二ホイール5a乃至5dのうちの少なくとも3輪が接地面に接触しているので、安定性も高い。   FIG. 9 shows a movement posture when a convex portion exists on the ground contact surface of the omni-wheel 5d and the omni-wheel 5d runs over the convex portion. In this case, since the omni-wheel 5d rides on the convex portion, the second flat plate 2B rotates clockwise around the shaft member 14 with respect to the first flat plate 2A, and the flat surface of the first flat plate 2A On the other hand, the plane of the second flat plate 2B has a predetermined inclination. With this rotation, the wheel cover member 11d fluctuates in the direction approaching the third flat plate 10, but the range in which it can fluctuate can be preset by the regulating members 16c and 16d. Due to such a variation, the gap d1 between the third flat plate 10 and the wheel cover member 11d becomes shorter than the gap during normal running shown in FIG. Accordingly, the gap d2 between the third flat plate 10 and the wheel cover member 11c becomes longer than the gap during normal running shown in FIG. As described above, the omnidirectional mobile trolley 1 maintains the equilibrium state of the load placed on the third flat plate 10 by the rotation of the second flat plate 2B around the shaft member 14 with respect to the first flat plate 2A. , Straight running stability can be maintained. Further, even under the above fluctuation, at least three of the four omni-wheels 5a to 5d are in contact with the ground contact surface, so that the stability is high.

以上説明したように、本発明の実施形態によれば、以下の効果が奏される。   As described above, according to the embodiment of the present invention, the following effects can be obtained.

It further includes restriction members 16a to 16d for restricting fluctuations of the wheel cover members 11c and 11d with respect to the third flat plate 10 in the height direction. According to this configuration, the fluctuation of the second flat plate 2B with respect to the first flat plate 2A due to the rotation around the shaft member 14 can be restricted, so that the equilibrium state of the third flat plate is stabilized while maintaining the straight running stability. It is possible to maintain the quality.

さらに、規制部材16a乃至16dは、位置決め部材17a乃至17dを更に有し、規制部材16a乃至16dは、位置決め部材17a乃至17dにより第3の平板10から第2の平板2Bへの突出量を調整することで、規制範囲が調整可能である。この構成によれば、使用環境に応じて、規制範囲を調整できるので、環境適応性が高い全方向移動台車1を実現することが可能となる。   Further, the regulating members 16a to 16d further include positioning members 17a to 17d, and the regulating members 16a to 16d adjust the amount of protrusion from the third flat plate 10 to the second flat plate 2B by the positioning members 17a to 17d. Thus, the regulation range can be adjusted. According to this configuration, the regulation range can be adjusted according to the use environment, so that the omnidirectional mobile trolley 1 with high environmental adaptability can be realized.
