Abstract

Provided is a high stiffness engagement chain unit wherein the inclination and buckling of a pair of engagement chains for linear operation are reliably restrained without the need to install an auxiliary guiding means for restraining buckling or inclination, thereby increasing durability, and wherein the chain engagement attitude is reliably maintained in a linear way, thereby realizing stable departure and return movements of a driven object. As an embodiment of the above, there is provided a high stiffness engagement chain unit (100) comprising a pair of engagement chains for linear operation (110) which become stiffly integrated together by engaging with each other by means of a pair of main sprockets (A) and which mutually disengage from each other by deviating from the chain engagement direction to the chain divergence direction, thereby flexibly diverging from each other; and a buckling restraining engagement chain (120) which laterally approaches the pair of engagement chains for linear operation (110) by means of an auxiliary sprocket (B), and which disengage from the pair of engagement chains for linear operation (110) and thereby diverge from the pair of engagement chains for linear operation (110).

Description

高剛性噛合チェーンユニットHigh rigidity mesh chain unit

　本発明は、各種製造分野の製造設備、運輸分野の移送設備、医療福祉分野の介護設備、芸術分野の舞台設備などに用いて被駆動物を設置面に対して平行に進退動させる駆動装置に組み込まれる高剛性噛合チェーンユニットに関するものである。
The present invention provides a drive device for moving a driven object forward and backward in parallel to an installation surface for use in manufacturing equipment in various manufacturing fields, transport equipment in the transportation field, nursing care equipment in the medical and welfare field, stage equipment in the art field, and the like. The present invention relates to a highly rigid meshing chain unit to be incorporated.

　従来、駆動装置として、相互に噛み合って一体的に昇降する一対の噛合チェーン、所謂、チャックチェーンを用いて重量物などの被駆動物を昇降移動させる駆動装置がある（例えば、特許文献１参照。）。
2. Description of the Related Art Conventionally, as a drive device, there is a drive device that moves a driven object such as a heavy object up and down using a pair of meshing chains that mesh with each other and move up and down integrally, so-called a chuck chain (see, for example, Patent Document 1). ).

特許第３３７０９２８号公報（特許請求の範囲、図１）Japanese Patent No. 3370928 (Claims, FIG. 1)

　ところが、従来の噛合チェーンでは、被昇降物が荷重支持部材に偏在した状態で搭載された場合などに一対の噛合チェーンに対して偏荷重が負荷されて、一対の噛合チェーンが垂直状態から傾斜状態になることがあるため、噛合チェーンが座屈し易くなり、チェーン耐久性を損なうとともに、噛合チェーンの横揺れに起因する不安定な昇降動作を生じる虞れがあるという昇降操作上の問題があった。
However, in the conventional mesh chain, when the object to be lifted is mounted in a state of being unevenly distributed on the load support member, an unbalanced load is applied to the pair of mesh chains, and the pair of mesh chains is inclined from the vertical state. As a result, there is a problem in the lifting operation that the meshing chain is likely to buckle, impairing the chain durability, and may cause an unstable lifting operation due to the rolling of the meshing chain. .

The high-rigid meshing chain unit 100 of the present embodiment obtained in this way is arranged so as to face the pair of main sprockets A and meshes with each other while being deflected from the chain branching direction to the chain meshing direction, and is rigidly integrated. In addition, a pair of linear operation meshing chains 110 that are disengaged from each other while being deflected from the chain meshing direction to the chain branching direction by a pair of main sprockets A and a pair of linear operation meshing chains 110 are meshed with each other. In this state, the auxiliary sprocket B having the rotation axis B1 arranged orthogonal to the rotation axis A1 of the pair of main sprockets A is engaged from the side and engaged with the engagement of the linear operation meshing chain 110. A seat that is separated from the pair of linear operation meshing chains 110 by the sprocket B and branches off. And a suppressing engagement chains 120..

Therefore, since the buckling suppression engagement chain 120 is engaged with the pair of linear operation engagement chains 110 in a state of being engaged with each other and supported from the side, the pair of linear operation engagement chains 110 in the state of being engaged with each other.

The posture can be securely held in a straight line, and the driven object can be stably moved back and forth.

　また、前述したように一体化した高剛性噛合チェーンユニット１００の剛性を確保して座屈強度を向上するため、高剛性噛合チェーンユニット１００の座屈や傾斜を抑制する補助ガイド手段の設置を必要とすることなく、被駆動物の安定した進退駆動を実現でき、高剛性噛合チェーンユニット１００を組み込んだ噛合チェーン式駆動装置Ｅの装置全体が複雑になることを回避して、装置設計に関する自由度を確保できる。
Further, as described above, in order to secure the rigidity of the integrated high rigidity meshing chain unit 100 and improve the buckling strength, it is necessary to install auxiliary guide means for suppressing the buckling and inclination of the high rigidity meshing chain unit 100. Therefore, it is possible to realize a stable forward / backward drive of the driven object, avoiding the complexity of the entire device of the meshing chain type drive device E incorporating the high-rigidity meshing chain unit 100, and freedom in device design.
