Description

本発明は、一般住宅や集合住宅に用いられるエレベータ装置に設けられるエレベータ乗場のエレベータ装置に関するものである。   The present invention relates to an elevator apparatus for an elevator hall provided in an elevator apparatus used in a general house or a collective house.

従来からエレベータ装置は商業施設のみならず集合住宅、一般住宅にも設置されるようになっていて、特に一般住宅においては高齢者増に伴い、設置が進んできている。このうち作動音が比較的低い油圧などの液圧式と呼ばれるエレベータ装置が、一般家庭向けに普及している（特許文献１等）。   Conventionally, elevator apparatuses have been installed not only in commercial facilities but also in apartment houses and ordinary houses, and in particular in ordinary houses, the installation has been progressing with the increase in the number of elderly people. Among them, an elevator apparatus called a hydraulic type such as a hydraulic pressure whose operation noise is relatively low is widely used for general households (Patent Document 1, etc.).

また、停電などが発生した場合には、補助バッテリー、無停電電源等の補助機能を用いて、エレベータかごを下層階に降下させ、安全に利用者を脱出させる、という機能も備わっている。液圧式のエレベータ装置では、エレベータかごを昇降させる液圧式ジャッキに導入されている液体を、バルブなどを開放し、例えばエレベータかごの自重で放出することで下降させることも行なわれている。   In addition, in the event of a power outage or the like, there is also a function of using an auxiliary function such as an auxiliary battery or uninterruptible power supply to lower the elevator car to the lower floor and safely escape the user. In the hydraulic elevator device, the liquid introduced into the hydraulic jack that raises and lowers the elevator car is lowered by opening a valve or the like, for example, by discharging it by its own weight.

一方で、停電などが復旧した場合に、下降原因が停電のみであった場合などは、特にメンテナンス担当者が個別に確認せずとも問題ない場合があるものの、制御回路等が異常状態で固定されてしまい、初期化をし、安全を確認する必要があったので、利用者にとって不満が残るところであった。
登録特許第３０４１０５４号公報 On the other hand, when the power failure is restored and the cause of the descent is only a power failure, the control circuit may be fixed in an abnormal state, although there may be no problem even if the maintenance staff does not check it individually. As a result, it was necessary to initialize and confirm safety, so there was a dissatisfaction for users.
Japanese Patent No. 3041054

本願発明は、上記背景技術に鑑みて発明されたものであり、その課題は、停電などが生じた場合であっても、運転再開時に支障が出にくいエレベータ装置を提供することである。   The present invention has been invented in view of the above-described background art, and an object of the present invention is to provide an elevator apparatus that is less likely to cause trouble when restarting operation even when a power failure occurs.

上記課題を解決するために、本願発明の請求項１に係るエレベータ装置は、 液圧式ジャッキでエレベータかごを直接昇降させるエレベータ装置において、該エレベータ装置は、液圧式ジャッキと液体タンクとの連結路中にある開閉バルブを開放し液圧式ジャッキから液体を液体タンクに戻しながらエレベータかごを所定階に下降させるとともに、この下降時に、液体を液圧式ジャッキに供給するための駆動ポンプを作動させず、同駆動ポンプの制御回路に対し該制御回路に異常状態が残らないようにして運転再開を可能な状態とする初期化を行うことを特徴とするエレベータ装置とすることを特徴としている。 In order to solve the above-mentioned problems, an elevator apparatus according to claim 1 of the present invention is an elevator apparatus that directly lifts and lowers an elevator car with a hydraulic jack, and the elevator apparatus is in a connection path between the hydraulic jack and the liquid tank. The elevator car is lowered to a predetermined floor while returning the liquid from the hydraulic jack to the liquid tank by opening the on-off valve at the same time, and the drive pump for supplying the liquid to the hydraulic jack is not operated at the time of the lowering. The elevator apparatus is characterized in that initialization is performed so that an abnormal state does not remain in the control circuit of the drive pump so that the operation can be resumed .

また本願発明の請求項２に係るエレベータ装置では、上記に加え、駆動ポンプがインバータ制御式モータで駆動され、初期化される駆動ポンプの制御回路が少なくとも該インバータ制御回路を含むことを特徴としている。   In addition to the above, the elevator apparatus according to claim 2 of the present invention is characterized in that the drive pump is driven by an inverter-controlled motor, and the drive pump control circuit to be initialized includes at least the inverter control circuit. .

また本願発明の請求項３に係るエレベータ装置では、上記に加え、初期化のための信号として、開閉バルブの開放制御信号としたことを特徴としている。   In addition to the above, the elevator apparatus according to claim 3 of the present invention is characterized in that an opening / closing valve opening control signal is used as a signal for initialization.

また本願発明の請求項４に係るエレベータ装置では、上記に加え、初期化のタイミングを、エレベータかごが着床した後としたことを特徴としている。   The elevator apparatus according to claim 4 of the present invention is characterized in that, in addition to the above, the initialization timing is after the elevator car has landed.

本願発明の請求項１に係るエレベータ装置では、エレベータかごの下降に伴い、駆動ポンプの制御回路を初期化したことで、停電等に伴う影響が駆動ポンプの制御回路に残ることを防止でき、運転再開を簡便に行なわしめることができる。   In the elevator apparatus according to claim 1 of the present invention, the drive pump control circuit is initialized along with the lowering of the elevator car, so that it is possible to prevent the influence due to a power failure or the like from remaining in the drive pump control circuit, Restarting can be performed easily.

本願発明の請求項２に係るエレベータ装置ではさらに、インバータ制御回路を必ず初期化するようにしたので、停電等に伴う影響が一番でやすい部位を確実に初期化することができる。   In the elevator apparatus according to claim 2 of the present invention, since the inverter control circuit is always initialized, it is possible to reliably initialize the portion most likely to be affected by a power failure or the like.

本願発明の請求項３に係るエレベータ装置ではさらに、停電等に関わらず常に下降時に初期化が行なわれるので、当該制御に関し、複雑な回路構成とする必要が無くなり、簡単に構成することができる。   Further, in the elevator apparatus according to the third aspect of the present invention, initialization is always performed when the vehicle descends regardless of a power failure or the like, so that it is not necessary to have a complicated circuit configuration for the control, and the configuration can be simplified.

本願発明の請求項４に係るエレベータ装置ではさらに、着床後にこれら初期化を行なわしめるので、万一駆動ポンプ等、作動中に初期化が行なわれると安全性に問題がある場合でも初期化ができるようになっている。   In the elevator apparatus according to claim 4 of the present invention, since these initializations are performed after landing, even if there is a problem in safety if initialization is performed during operation of a drive pump or the like, initialization is possible. It can be done.

本願発明の最良の形態を図１に示される以下の実施形態にて説明する。   The best mode of the present invention will be described in the following embodiment shown in FIG.

本実施形態では、図１に本願発明の要部として示したように、液圧式ジャッキ１でエレベータかご２を直接昇降させるエレベータ装置３において、該エレベータ装置３は、液圧式ジャッキ１と液体タンク４との連結路中にあるエレベータかご２下降用の開閉バルブ５を開放し液圧式ジャッキ１から液体を液体タンク４に戻しながらエレベータかご２を所定階に下降させるとともに、液体を液圧式ジャッキ１に供給するための駆動ポンプの制御回路７を初期化することを特徴とするエレベータ装置３としている。なお、液体には油、水その他の種々の液体が用いられる。   In the present embodiment, as shown in FIG. 1 as a main part of the present invention, in an elevator apparatus 3 that directly lifts and lowers an elevator car 2 with a hydraulic jack 1, the elevator apparatus 3 includes a hydraulic jack 1 and a liquid tank 4. The opening / closing valve 5 for lowering the elevator car 2 in the connecting path is opened and the elevator car 2 is lowered to a predetermined floor while returning the liquid from the hydraulic jack 1 to the liquid tank 4, and the liquid is supplied to the hydraulic jack 1. The elevator apparatus 3 is characterized by initializing a control circuit 7 of a drive pump for supplying. In addition, oil, water, and other various liquids are used for the liquid.

そして駆動ポンプ６がインバータ制御式モータ で駆動され、初期化される駆動ポンプ６の制御回路として少なくとも該インバータ制御回路７１を含めていて、さらに初期化のための信号として、下降用の開閉バルブ５の開放制御信号を活用している。   The drive pump 6 is driven by an inverter-controlled motor and includes at least the inverter control circuit 71 as a control circuit for the drive pump 6 to be initialized. Further, the opening / closing valve 5 for lowering is used as a signal for initialization. The open control signal is used.

このエレベータ装置３は、昇降路内に液圧式ジャッキ１、プラットホーム２１上に載置され液圧式ジャッキ１により昇降されるエレベータかご２が配置され、液圧式ジャッキ１は、中途に開閉バルブ５を介して液体タンク４から液体を駆動ポンプ６によりホースなどの管体により連結されている。そしてこれら制御をつかさどるのが、エレベータ装置の制御装置８である。これにより、利用者等の各種操作に伴い、例えばエレベータかご２が上昇するときは、上昇用バルブ５１に「開放」信号が入力され、次いで、駆動ポンプ６を作動させるために駆動ポンプの制御回路７に「駆動」信号が入力される。   The elevator apparatus 3 is provided with a hydraulic jack 1 in a hoistway, and an elevator car 2 placed on a platform 21 and moved up and down by the hydraulic jack 1. The liquid from the liquid tank 4 is connected by a tube such as a hose by a drive pump 6. The control device 8 of the elevator apparatus is responsible for these controls. As a result, when the elevator car 2 rises with various operations by the user or the like, for example, an “open” signal is input to the lift valve 51, and then a drive pump control circuit for operating the drive pump 6 The “drive” signal is input to 7.

下降時には、駆動ポンプ６は作動させず、エレベータ回路の制御回路８から下降用バルブ５２に「開放」信号を入力し該バルブを開放する。そしてエレベータかご２の自重で、液圧式ジャッキ１から液体を放出され液体タンク４に液体が格納される。   At the time of lowering, the drive pump 6 is not operated, and an “open” signal is input to the lowering valve 52 from the control circuit 8 of the elevator circuit to open the valve. The liquid is discharged from the hydraulic jack 1 by the weight of the elevator car 2 and stored in the liquid tank 4.

そのため、インバータ制御回路７１の初期化タイミングは、エレベータかご２が下降し始めたとき、すなわち、開閉バルブ５が開いた時に同時に初期化を行なわせることができる。もちろん遅延回路を設け一定のタイムラグを設けても良い。そして初期化信号は、開閉バルブ５の「開放」を指示するエレベータ装置３の制御回路からの信号であってもよいし、開閉バルブ５が開放されたことを検出して発生させても良い。また、停電等により作動する特別な回路（例えば「停電救出回路」）によって特別に初期化信号を発生させても良い。   Therefore, the initialization timing of the inverter control circuit 71 can be initialized simultaneously when the elevator car 2 starts to descend, that is, when the opening / closing valve 5 is opened. Of course, a delay circuit may be provided to provide a certain time lag. The initialization signal may be a signal from the control circuit of the elevator apparatus 3 instructing “open” of the open / close valve 5 or may be generated by detecting that the open / close valve 5 is open. In addition, a special initialization signal may be generated by a special circuit that operates due to a power failure or the like (for example, “power failure rescue circuit”).

なお開閉バルブ５が開放されたことを検出して行なわしめる場合は、開閉バルブ５自体に何らかの不具合が発生し誤発生することを考慮し、例えば駆動ポンプ６の作動信号と論理積をとるなどする必要があると考えられる。   When detecting that the opening / closing valve 5 has been opened, taking into account that the opening / closing valve 5 itself has some trouble and is erroneously generated, for example, a logical product with the operation signal of the drive pump 6 is taken. It is considered necessary.

ここで駆動ポンプ６により液体タンク４から液体を開閉バルブ５を通して液圧式ジャッキ１に注入しているが、該開閉バルブ５は、内部に上昇用バルブ５１、下降用バルブ５２を有していて、エレベータかご２の昇降に伴い、適宜エレベータ装置制御回路８からの開閉信号により開閉され用いられる。   Here, liquid is injected from the liquid tank 4 to the hydraulic jack 1 through the open / close valve 5 by the drive pump 6, and the open / close valve 5 has an ascending valve 51 and a descending valve 52 inside, As the elevator car 2 moves up and down, the elevator car 2 is appropriately opened and closed by an open / close signal from the elevator apparatus control circuit 8.

本実施形態のようにエレベータ装置１を構成した場合、次のような場合などに特に効果があると考えられる。   When the elevator apparatus 1 is configured as in the present embodiment, it is considered that the following effects are particularly effective.

すなわち、停電が発生し自動着床した場合に、通常なら復旧のためのメンテナンス担当者が現場を確認し、復旧を行なわしめることが望ましいところ、現場に出動する必要があるが、例えば、メンテナンス担当者と電話で確認し、利用者がその指示に従い確認を行なわせることができるようになる。そうすると、不具合の有無を確認し、必要があればメンテナンス担当者が現場に出向くことが可能となるので、地域全体が停電し、少数のメンテナンス担当者だけでは復旧に時間がかかる場合であっても、コールセンターなどの担当者がマニュアルに従い確認し、不具合が起こっている判断される場合のみ現場に担当者を派遣するなど、柔軟な運用が可能になると考えられる。   In other words, when a power outage occurs and an automatic landing occurs, it is usually desirable for maintenance personnel to check the site and restore it, but it is necessary to be dispatched to the site. The user can be confirmed by telephone and the user can confirm according to the instruction. Then, if there is a problem, it will be possible for maintenance personnel to go to the site if necessary, so the entire area will be out of power, and even a small number of maintenance personnel will take time to recover. It is thought that flexible operation is possible, such as dispatching personnel to the site only when personnel in charge such as call centers check according to the manual and it is determined that a malfunction has occurred.

また本実施形態のように、エレベータかご２の下降時には駆動ポンプ６は動作せず、そして常にエレベータかご２の下降に伴い信号を発生させるようにすれば、発生タイミングなどを細かく設定する必要が無く、簡易に初期化を行なわせることができる。この場合、通常のエレベータかご２の下降に伴い、常に初期化が行なわれることになる。   Further, as in this embodiment, when the elevator car 2 is lowered, the drive pump 6 does not operate, and if a signal is always generated when the elevator car 2 is lowered, it is not necessary to set the generation timing and the like in detail. Initialization can be easily performed. In this case, the initialization is always performed as the normal elevator car 2 is lowered.

なお、初期化のタイミングを上記実施形態と異なり、エレベータかご２が着床した後としたこととすると、停電時などで自動着床制御をしている際に、駆動ポンプ６が着床時にも動作されている場合であっても、駆動ポンプ６に不用意に初期化信号が入り、結果、不具合が生じることを防ぐことができる。   Note that, unlike the above embodiment, the initialization timing is after the elevator car 2 has landed. When automatic landing control is performed during a power failure or the like, the drive pump 6 is also Even if it is operating, it is possible to prevent the drive pump 6 from inadvertently receiving an initialization signal, resulting in a malfunction.
