Description

本発明は、ベルト伝動機構を使用してエレベータかご等の往復移動体を往復駆動する駆動装置の発送方法に関するものである。   The present invention relates to a delivery method for a drive device that reciprocally drives a reciprocating moving body such as an elevator car using a belt transmission mechanism.

図１は、出願人が提案している方式の駆動機構を備えた駆動装置であり（特許文献１参照）、図示省略しているが、主ロープ３の一側にはエレベータかご、他側にはカウンターウェイトが設けられている。駆動装置４０はフレーム４１にシーブ４２を取り付けるとともに、該シーブ４２の上方と両側の３箇所にプーリ４３，４４，４５を配置し、これらのプーリ４３，４４，４５にベルト４６を張設し、このベルト４６によってシーブ４２に巻き付けられた主ロープ３をシーブ４２に押圧する。上方のプーリ４３はフレーム４１の背面に取り付けられたモータ（図示省略）に連結されており、ベルト４６の周回移動により、シーブ４２と主ロープ３を移動させてかごを昇降させる構成になっている。また両側のプーリ４４，４５はそれぞれ位置調節機構４７によって、フレーム４１に対して高さ位置の調節が可能取り付けられており、これら高さ位置を調節することによってベルト４６の張力を調節することができる。４８は非常時等に主ロープ３を挟持するロープグリッパーで油圧等によって動作する。４９はモータの回動状態を検出する検出装置、例えばロータリーエンコーダ、５０はモータのブレーキである。   FIG. 1 shows a drive device having a drive mechanism of the method proposed by the applicant (see Patent Document 1), which is omitted in the figure, but one side of the main rope 3 is on the elevator car and the other side is on the other side. Has a counterweight. The drive device 40 attaches a sheave 42 to a frame 41, and arranges pulleys 43, 44, 45 at three locations above and on both sides of the sheave 42, and stretches a belt 46 around these pulleys 43, 44, 45, The main rope 3 wound around the sheave 42 is pressed against the sheave 42 by the belt 46. The upper pulley 43 is connected to a motor (not shown) attached to the back surface of the frame 41, and is configured to move the sheave 42 and the main rope 3 to move the car up and down by the circular movement of the belt 46. . The pulleys 44 and 45 on both sides are attached to the frame 41 by a position adjusting mechanism 47 so that the height position can be adjusted. By adjusting these height positions, the tension of the belt 46 can be adjusted. it can. Reference numeral 48 denotes a rope gripper that holds the main rope 3 in an emergency or the like, and operates by hydraulic pressure or the like. Reference numeral 49 is a detection device that detects the rotational state of the motor, for example, a rotary encoder, and 50 is a brake for the motor.

この装置を据付現場へ発送するときは、ベルト４６、主ロープ３、駆動装置４０はそれぞれ別々に梱包して送られるのが普通である。
またベルト４６は使用時に伸びを生じ、特に使用開始時には伸び量が大きいため、ベルト４６の装着時にこの初期伸びを処理しておく必要がある。ベルト生産工場等で予めベルト４６の初期伸び処理がされていればよいが、そうでないときは何らかの方法で初期伸び処理をする必要がある。この方法として例えば最近出願人が提案した特願２００２−３２３８１０号に記載したものがある。これを図２により説明する。図において、１はケース、２は蓋，４，５はその軸が長穴６によりケース１に枢着されたプーリ、７，８はプーリ４，５から伸びたねじ部で、ナット部９で連結されており、このナット部９を回動することによりプーリ４，５の間隔を調整する構成である。
そしてプーリ４，５にベルト４６を巻き付けて、ナット９を回し、使用時と同等の張力をベルト４６に掛けた状態で発送する。 When this apparatus is shipped to the installation site, the belt 46, the main rope 3, and the driving apparatus 40 are usually packed and sent separately.
In addition, the belt 46 is stretched during use, and the elongation amount is particularly large at the start of use. Therefore, it is necessary to process this initial stretch when the belt 46 is mounted. It is sufficient that the belt 46 is initially stretched in advance at a belt production factory or the like, but if this is not the case, it is necessary to perform the initial stretching process by some method. An example of this method is described in Japanese Patent Application No. 2002-323810 recently proposed by the applicant. This will be described with reference to FIG. In the figure, 1 is a case, 2 is a lid, 4 and 5 are pulleys whose shafts are pivotally attached to the case 1 by a long hole 6, 7 and 8 are thread portions extending from the pulleys 4 and 5, and nut portions 9 It is the structure which is connected and adjusts the space | interval of the pulleys 4 and 5 by rotating this nut part 9. As shown in FIG.
Then, the belt 46 is wound around the pulleys 4 and 5, the nut 9 is turned, and the belt 46 is shipped in a state where a tension equal to that in use is applied to the belt 46.

したがって、ベルト４６に初期伸び処理がされていないときには、図２のようなベルト初期伸び処理装置にベルト４６を掛けた状態で、またベルト４６に初期伸び処理がされているときには、単に梱包して、現場へ発送している。
国際公開第０２／０６４４８２号パンフレット Therefore, when the belt 46 is not initially stretched, the belt 46 is hung on the belt initial stretch processing apparatus as shown in FIG. 2, and when the belt 46 is initially stretched, it is simply packed. , Is shipping to the site.
International Publication No. 02/064482 Pamphlet

前記従来の発送方法では、駆動装置４０とベルト４６は別々梱包されて発送されるため、発送コストが増大するという問題があった。また、運搬中に駆動装置４０のシーブ４２が空回りするのを防止するためにシーブ４２を固定しておく必要がある。   In the conventional shipping method, the driving device 40 and the belt 46 are separately packed and shipped, so there is a problem that the shipping cost increases. Further, it is necessary to fix the sheave 42 in order to prevent the sheave 42 of the drive device 40 from spinning during transportation.

本発明は、駆動装置４０にベルト４６を取り付けた状態で駆動装置４０を発送することにより前記問題を解決したものである。
またベルト４６に初期伸び処理がされていないときにはプーリ４４，４５の位置を調整して、ベルト４６に使用時と同等の張力を掛けた状態で発送するものである。 The present invention solves the above problem by shipping the drive device 40 with the belt 46 attached to the drive device 40.
When the belt 46 is not initially stretched, the positions of the pulleys 44 and 45 are adjusted, and the belt 46 is shipped in a state where a tension equal to that in use is applied.

本発明によれば、駆動装置４０とベルト４６を一緒に発送できるため、発送コストが抑えられ、またベルト４６の初期伸び処理も容易に行うことができる。   According to the present invention, since the driving device 40 and the belt 46 can be shipped together, the shipping cost can be reduced, and the initial elongation process of the belt 46 can be easily performed.

本発明の実施の形態は、図１に示すように駆動装置４０にベルト４６を掛けておきこの状態でベルト４６と駆動装置４０を一緒に発送するものである。
ここで、位置調節機構４７によって、プーリ４５，４６の高さ位置を調節することにより、ベルト４６の張力を調節する。即ち予めベルト４６に初期伸び処理がされているときには、運搬中にシーブ４２が回転しない程度にベルト４６の張力を調節しておく。また、ベルト４６に初期伸び処理がされていないときは、ベルト４６に使用時と同等の張力を掛ける。このとき主ロープ３が掛かっていないため、プーリ４５，４６の高さ位置は使用時より更に下方にくることになる。なお、主ロープ３の代わりにベルト状の張力部材が使用されることもあるが、同様に調節される。 In the embodiment of the present invention, a belt 46 is hung on a drive device 40 as shown in FIG. 1, and the belt 46 and the drive device 40 are shipped together in this state.
Here, the tension of the belt 46 is adjusted by adjusting the height positions of the pulleys 45 and 46 by the position adjusting mechanism 47. That is, when the belt 46 is subjected to the initial elongation process in advance, the tension of the belt 46 is adjusted so that the sheave 42 does not rotate during transportation. Further, when the belt 46 is not initially stretched, the belt 46 is applied with the same tension as that used. At this time, since the main rope 3 is not hung, the height positions of the pulleys 45 and 46 are further lowered than in use. A belt-like tension member may be used instead of the main rope 3, but the same adjustment is performed.
