Description
上記した回転機構では、ベルトが環状であるため、ベルト交換作業の際に第1部分と第2部分とを分離する必要があり、作業が面倒で時間がかかるだけでなく、作業者の負担も大きくなる。また、ベルトを環状とせずに、端部を有するベルト(いわゆるオープンエンドベルト)を円筒部材の外周面に巻き付け、両端を突き合わせた状態で円筒部材に固定する構成も考えられる。しかし、端部を有するベルトを用いる構成では、ベルトの両端が円筒部材に固定されるため、この固定部分を回転駆動部が手繰り寄せることができず、第1部分と第2部分との相対的な回転角度範囲に制限が生じてしまう。すなわち、端部を有するベルトを用いる構成では、第1部分と第2部分との相対的な回転を0°から360°未満でしか実現できない。 In the rotating mechanism described above, since the belt is annular, it is necessary to separate the first part and the second part when replacing the belt, which not only makes the work troublesome and time-consuming, but also puts a burden on the operator. growing. Alternatively, instead of making the belt annular, a belt having ends (a so-called open- end belt) may be wound around the outer circumferential surface of a cylindrical member and fixed to the cylindrical member with both ends abutted against each other. However, in a configuration using a belt having end portions, since both ends of the belt are fixed to the cylindrical member, the rotary drive unit cannot pull these fixed portions together, and the relative relationship between the first portion and the second portion is There is a limit to the rotation angle range. That is, in a configuration using a belt having end portions, relative rotation between the first portion and the second portion can only be realized from 0° to less than 360°.
本発明は、巻きかけ伝動部材の交換作業を容易に行うことを可能として作業者の負担を軽減しつつ、第1部分と第2部分とを0°から360°以上相対的に回転させることが可能な回転機構及びこの回転機構を備える天井搬送車を提供することを目的とする。 The present invention is capable of relatively rotating the first part and the second part by 360 degrees or more from 0 degrees while making it possible to easily replace the wrapped transmission member and reducing the burden on the worker. It is an object of the present invention to provide a rotation mechanism capable of rotating and an overhead transport vehicle equipped with this rotation mechanism.
上記態様の回転機構によれば、巻き掛け伝動部材が端部を有する構成であるため、巻きかけ伝動部材の両端の固定を解除することで、ベルトを容易に交換することができる。その結果、ベルト交換作業を行う作業者の負担を軽減できる。また、巻き掛け伝動部材が円筒部材の外周の一周を越えて、かつ回転の軸線方向にずらして巻き付けられるため、第1部分と第2部分とを360°以上相対的に回転させることができる。すなわち、端部を有するベルト(環状でないベルト)を用いる場合であっても、第1部分と第2部分とをより大きな回転角度範囲で相対的に回転させることができる。 According to the rotation mechanism of the above aspect, since the winding transmission member has an end portion, the belt can be easily replaced by releasing the fixation of both ends of the winding transmission member. As a result, the burden on the worker who replaces the belt can be reduced. In addition, since the wrapped transmission member is wrapped around the cylindrical member beyond one circumference and shifted in the direction of the axis of rotation, the first part and the second part can be rotated relative to each other by 360 degrees or more. . That is, even when using a belt having an end portion (a belt that is not annular), the first portion and the second portion can be relatively rotated over a larger rotation angle range.
また、上記態様の回転機構において、腕部が、軸線に対する放射方向に沿って延びる位置に弾性的に保持される構成であってもよい。この構成によれば、腕部が放射方向に延びた状態で弾性的に保持されているので、被係止部を確実に当接部に当接させることができる。また、上記態様の回転機構において、被係止部が、当接部に接触する部分にテーパ面が設けられる構成であってもよい。この構成によれば、テーパ面に当接部が当たることで、腕部を容易に揺動させることができる。また、上記態様の回転機構において、回転駆動部が、巻き掛け伝動部材の軸線方向におけるずれに対応して、軸線と平行な方向において巻き掛け伝動部材の幅よりも長い駆動面を備える構成であってもよい。この構成によれば、巻き掛け伝動部材が回転駆動部から外れることを抑制できる。 Further, in the rotation mechanism of the above aspect, the arm portion may be elastically held at a position extending in a radial direction with respect to the axis. According to this configuration, since the arm portion is elastically held in a state extending in the radial direction, the locked portion can be reliably brought into contact with the contact portion. Further, in the rotation mechanism of the above aspect, the locked portion may be configured to have a tapered surface in a portion that contacts the abutting portion. According to this configuration, the arm portion can be easily swung by the contact portion coming into contact with the tapered surface. Further, in the rotation mechanism of the above aspect, the rotation drive section may include a drive surface that is longer than the width of the wrapping power transmission member in a direction parallel to the axis in order to accommodate the deviation in the axial direction of the wrapping power transmission member. You can. According to this configuration, it is possible to suppress the winding transmission member from coming off from the rotation drive section.
巻き掛け伝動部材12の第1端部12a及び第2端部12bは、それぞれ凹部11a、11bに固定されているので、固定具13a、13bが円筒部材11の外周面11cから外側に突出しない。この構成により、後述する回転駆動部23及びプーリ24が固定具13a、13bと干渉するのを防止できる。また、巻き掛け伝動部材12の内面は、凹凸がない面であってもよいし、後述する回転駆動部23と噛み合うことが可能な波形が形成されてもよい。また、巻き掛け伝動部材12は、弾性を有してもよいし、弾性を有しなくてもよい。 Since the first end 12a and second end 12b of the winding transmission member 12 are fixed to the recesses 11a and 11b, respectively, the fixtures 13a and 13b do not protrude outward from the outer peripheral surface 11c of the cylindrical member 11. This configuration can prevent the rotation drive unit 23 and pulley 24, which will be described later, from interfering with the fixtures 13a and 13b. Moreover, the inner surface of the winding transmission member 12 may be a surface without unevenness, or may be formed with a waveform that can mesh with a rotational drive section 23 described later. Moreover, the winding transmission member 12 may or may not have elasticity.
第1凹部53と第2凹部54とは、軸線AX1まわりの周方向において離間して配置されている。その結果、第1凹部53により被係止部60が係止された第2部分20の回転位置と、第2凹部54により被係止部60が係止された第2部分20の回転位置とでは、第2部分20が第1部分10に対して1回転以上した状態となっている。すなわち、第1部分10と第2部分20との相対的な回転角度範囲を0°から360°以上となるように設定している。 The first recess 53 and the second recess 54 are spaced apart in the circumferential direction around the axis AX1. As a result, the rotational position of the second portion 20 in which the locked portion 60 is locked by the first recess 53 and the rotational position of the second portion 20 in which the locked portion 60 is locked by the second recess 54 are determined. In this case, the second portion 20 has made one or more rotations relative to the first portion 10. That is, the relative rotation angle range between the first portion 10 and the second portion 20 is set to be from 0° to 360° or more.
