以下、本発明の実施の形態を、図を用いて説明する。図１は、補巻付電動巻上機の構成を示す。補巻付電動巻上機は、主巻側巻上部１、補巻側巻上部２を有する。主巻側巻上部１は主巻側巻上電動機３により、主巻側ドラム５を回転させ、主巻側ワイヤーロープ７を巻取ることで、主巻側フック９の巻上、巻下を行っている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a configuration of an electric hoist with auxiliary winding. The auxiliary winding electric hoist has a main winding side winding upper part 1 and an auxiliary winding side winding upper part 2. The main winding side hoisting part 1 rotates the main winding side drum 5 by the main winding side hoisting motor 3 and winds the main winding side wire rope 7 to wind and lower the main winding side hook 9. ing.

また、補巻側巻上部２の補巻側巻上電動機４により、補巻側ドラム６を回転させ、補巻側ワイヤーロープ８を巻取ることで、補巻側フック１０の巻上、巻下を行っている。   Further, the auxiliary winding side drum 6 is rotated by the auxiliary winding side hoisting motor 4 of the auxiliary winding side winding upper portion 2 and the auxiliary winding side wire rope 8 is wound up, whereby the auxiliary winding side hook 10 is wound and unwound. It is carried out.

さらに、入力装置１３により、主巻側制御部１１、補巻側制御部１２の操作を行い、主巻側巻上電動機３、補巻側巻上電動機４を制御する。   Furthermore, the main winding side control unit 11 and the auxiliary winding side control unit 12 are operated by the input device 13 to control the main winding side hoisting motor 3 and the auxiliary winding side hoisting motor 4.

図２は、従来の制御部構成を示す。従来の制御部は主巻側制御部１１と補巻側制御部１２の双方を有しており、入力装置１３により、主巻側インバータ制御部１４、補巻側インバータ制御部１５に操作指令入力することにより、主巻側インバータ１６、補巻側インバータ１７へインバータ駆動信号を出力する。   FIG. 2 shows a conventional control unit configuration. The conventional control unit has both the main winding side control unit 11 and the auxiliary winding side control unit 12, and operation commands are input to the main winding side inverter control unit 14 and the auxiliary winding side inverter control unit 15 by the input device 13. By doing so, an inverter drive signal is output to the main winding side inverter 16 and the auxiliary winding side inverter 17.

インバータ駆動信号の入力により、主巻側インバータ１６、補巻側インバータ１７は主巻側電動機５、補巻側電動機６へインバータ出力を行うことで、主巻側の巻上、巻下、補巻側の巻上、巻下動作を行う構成になっている。   In response to the input of the inverter drive signal, the main winding side inverter 16 and the auxiliary winding side inverter 17 output the inverter to the main winding side electric motor 5 and the auxiliary winding side electric motor 6, so that the main winding side winding, lowering and auxiliary winding are performed. It is the structure which performs the winding / lowering operation | movement of the side.

また、主巻側インバータ１６、補巻側インバータ１７は、それぞれ対応する電流検出部１８、１９を備えている。また、主巻側電動機５、補巻側電動機６には、それぞれ対応する電動機の回転に応じてパルス信号を出力するエンコーダ２０、２１を備えている。   Further, the main winding side inverter 16 and the auxiliary winding side inverter 17 are provided with corresponding current detection units 18 and 19, respectively. Further, the main winding side motor 5 and the auxiliary winding side motor 6 are respectively provided with encoders 20 and 21 that output pulse signals according to the rotation of the corresponding motor.

これらの電流検出部１８、１９、エンコーダ２０、２１により、主巻側、補巻側で各々荷重判別を行っている。電流値が一定以上または、インバータの出力周波数換算の回転数と、エンコーダにより検出した実回転数により電動機のスベリを検出し、スベリが一定以上の場合は、過荷重と判断する。   These current detection units 18 and 19 and encoders 20 and 21 perform load determination on the main winding side and the auxiliary winding side, respectively. The slip of the motor is detected based on the current value exceeding a certain value, or the rotation speed converted to the output frequency of the inverter and the actual rotation number detected by the encoder.

また、主巻側インバータ１６、補巻側インバータ１７は、それぞれ対応する電圧検出部２２、２３を備えており、巻下時の回生電力により直流電圧が規定した値以上のときに回生抵抗２４、２５で熱エネルギーとして消費、またはその他回生処理手段により電子部品の過電圧の保護を行う。   Further, the main winding side inverter 16 and the auxiliary winding side inverter 17 are provided with corresponding voltage detection units 22 and 23, respectively, and when the DC voltage is not less than a value specified by the regenerative power at the time of lowering, the regenerative resistor 24, At 25, the overvoltage of the electronic component is protected by consumption as thermal energy or by other regenerative processing means.

従来技術では、補巻付電動巻上機は、主巻側で１つの制御部、補巻側で１つの制御部の計２つの制御部により構成されていた。しかし、制御部が２つあるという点でメンテナンス時に主巻側、補巻側の、両方の制御部の確認が必要であり、また、２つの制御部を持つことにより制御部のコスト高などの問題点があった。   In the prior art, the auxiliary winding electric hoist has been configured by two control units, one control unit on the main winding side and one control unit on the auxiliary winding side. However, because there are two control units, it is necessary to check both the main winding side and the auxiliary winding side during maintenance, and having two control units increases the cost of the control unit. There was a problem.

図３は、本発明の制御部構成である。入力装置１３により、インバータ制御部２６に操作指令入力することにより、インバータ２７へインバータ駆動信号を出力する。インバータ駆動信号の入力により、インバータ２７は主巻側電動機５、補巻側電動機６へインバータ出力を行うことで、主巻側の巻上、巻下、補巻側の巻上、巻下動作を行う。   FIG. 3 shows the configuration of the control unit of the present invention. By inputting an operation command to the inverter control unit 26 by the input device 13, an inverter drive signal is output to the inverter 27. In response to the input of the inverter drive signal, the inverter 27 outputs the inverter to the main winding side electric motor 5 and the auxiliary winding side electric motor 6, thereby performing the main winding side winding and lowering, the auxiliary winding side winding and lowering operations. Do.

また、インバータ２６は、電流検出部２９を備え、また、主巻側電動機５、補巻側電動機６にはそれぞれ対応する電動機の回転に応じてパルス信号を出力するエンコーダ２０、２１を備えている。   The inverter 26 includes a current detector 29, and the main winding motor 5 and the auxiliary winding motor 6 include encoders 20 and 21 that output pulse signals according to the rotation of the corresponding motor. .

そして電流検出部２９、エンコーダ２０、２１により、主巻側、補巻側の荷重判別を行う。電流値が一定以上または、インバータの出力周波数換算の回転数と、エンコーダにより検出した実回転数により電動機のスベリを検出し、スベリが一定以上の場合は、過荷重と判断する。
また、インバータ２６は、電圧検出部３０を備えており、巻下時の回生電力により直流電圧が規定した値以上のときに回生抵抗３１で熱エネルギーとして消費、またはその他回生処理手段により電子部品の過電圧の保護を行う。 Then, the current detection unit 29 and the encoders 20 and 21 determine the load on the main winding side and the auxiliary winding side. The slip of the motor is detected based on the current value exceeding a certain value, or the rotation speed converted to the output frequency of the inverter and the actual rotation number detected by the encoder.
Further, the inverter 26 includes a voltage detection unit 30 that is consumed as heat energy by the regenerative resistor 31 when the DC voltage is equal to or higher than the value specified by the regenerative power at the time of lowering, or other regenerative processing means. Provide overvoltage protection.

入力装置１３による操作入力により、インバータ制御部２６は主巻、補巻インバータ出力切替用マグネットスイッチ２８により、主巻側電動機５、補巻側電動機６へのインバータ出力の切替え制御を行う。   In response to an operation input by the input device 13, the inverter control unit 26 performs switching control of the inverter output to the main winding side electric motor 5 and the auxiliary winding side electric motor 6 by the main switch and auxiliary winding inverter output switching magnet switch 28.

また、上記、主巻、補巻インバータ出力切替用マグネットスイッチ２８のうちの一つの接点（Ｂ接点）には、主巻/補巻切替えマグネットスイッチの状態監視部３２が接続されており、主巻、補巻インバータ出力切替用マグネットスイッチ２８が主巻/補巻の切替が正常に行われているかの状態監視を行う。   Further, a state monitoring unit 32 of the main winding / auxiliary winding switching magnet switch is connected to one of the contacts (B contact) of the main winding / auxiliary winding inverter output switching magnet switch 28. The auxiliary winding inverter output switching magnet switch 28 monitors whether the main winding / auxiliary winding switching is normally performed.

図４は、本発明の運転制御のフローチャート図である。補巻付電動巻上機は主巻側、補巻側の同時運転が行われないようにインターロックを行わなければならないため、タイマカウントによる主巻・補巻同時動作防止用のインターロック判定４０２、４１２を行う。また、切替えＭｇＳＷ状態監視による主巻・補巻同時動作防止用のインターロック判定４０３、４１３も行う。   FIG. 4 is a flowchart of the operation control of the present invention. The auxiliary winding electric hoist needs to be interlocked so that simultaneous operation of the main winding side and the auxiliary winding side is not performed. Therefore, the interlock determination 402 for preventing the simultaneous operation of the main winding and the auxiliary winding by the timer count. 412 is performed. In addition, interlock determinations 403 and 413 for preventing simultaneous operation of the main winding and the auxiliary winding by monitoring the switching MgSW state are also performed.

まず、主巻側巻上機の巻上または巻下運転操作を行う。（４０１）
次に補巻ブレーキ制動後、タイマカウントによって、２秒以上経過しているかの判別を行う。補巻ブレーキ制動後、２秒以上経過後の場合はステップ４０３へ、補巻ブレーキ制動後、２秒以上経過していない場合はステップ４０４へ移る。（４０２）
主巻側パラメータセット、また、主巻/補巻切替えマグネットスイッチの状態監視部３２により主巻側インバータ出力リレーＯＮか判別を行う。主巻側パラメータセット済、インバータ出力リレーＯＮの場合はステップ４０６へ、主巻側パラメータセット済、インバータ出力リレーＯＮしていない場合はステップ４０５へ移る。（４０３）
ステップ４０３で、主巻側パラメータセット済、インバータ出力リレーＯＮでない場合は、主巻側パラメータセット済、インバータ出力リレーＯＮを行い、ステップ４０６へ移る。（４０５）
一方、ステップ４０２で、補巻ブレーキ制動後、２秒以上経過していない場合、主巻側巻上機の運転を不可として終了する。（４０４）
ステップ４０６では主巻側巻上機の運転（インバータ出力）を行う。（４０６）主巻側巻上機の運転が可能である場合、主巻側巻上機の操作指令が巻下運転を行うか判別する。主巻側巻上機の巻下運転の場合はステップ４０８へ、巻下運転でない場合はステップ４０９へ移る。（４０７）
巻下運転の場合は、過荷重状態では主巻側、補巻側の巻上禁止状態となっているため、過荷重状態の主巻側、補巻側の巻上禁止状態を解除する。（４０８）
主巻側巻上機の運転終了か判別を行う。主巻側巻上機の運転終了の場合はステップ４１０へ移る。（４０９）
主巻側巻上機の運転を終了するものである場合、補巻側運転可能かの判別に用いるためタイマカウントによって、主巻ブレーキ制動後カウントを行い終了する。（４１０）
以上のフローチャートが本発明の主巻側の運転実施例となる。ステップ４０３の主巻インバータ出力リレーＯＮの条件は、ソフト上のリレーＯＮの有無だけでも、主補切替えＭｇＳＷの状態の両方の条件のどちらも含まれる。また、補巻側巻上機の動作も同様である。 First, the hoisting or lowering operation of the main winding side hoisting machine is performed. (401)
Next, after braking the auxiliary winding brake, it is determined whether or not 2 seconds or more have elapsed by the timer count. If 2 seconds or more have elapsed after the auxiliary winding brake braking, the process proceeds to step 403. If 2 seconds or more have not elapsed after the auxiliary winding brake braking, the process proceeds to step 404. (402)
Whether the main winding side inverter output relay is ON is determined by the main winding side parameter set and the state monitoring unit 32 of the main winding / auxiliary winding switching magnet switch. If the main winding side parameter has been set and the inverter output relay is ON, the process proceeds to step 406. If the main winding side parameter has been set and the inverter output relay is not ON, the process proceeds to step 405. (403)
If it is determined in step 403 that the main winding side parameter has been set and the inverter output relay is not ON, the main winding side parameter has been set and the inverter output relay is ON, and the routine proceeds to step 406. (405)
On the other hand, if 2 seconds or more have not elapsed after the supplementary brake braking in step 402, the operation of the main winding side hoisting machine is disabled and the operation is terminated. (404)
In step 406, the main winding side hoisting machine is operated (inverter output). (406) If the operation of the main winding side hoisting machine is possible, it is determined whether the operation command of the main winding side hoisting machine performs the lowering operation. If the main winding side hoisting machine is in the lowering operation, the process proceeds to step 408. If not, the process proceeds to step 409. (407)
In the case of the unwinding operation, in the overload state, the main winding side and the auxiliary winding side are prohibited from being wound, so the main winding side and the auxiliary winding side in the overload state are canceled. (408)
It is determined whether or not the main winding side hoisting machine is finished. When the operation of the main winding side hoisting machine is finished, the routine proceeds to step 410. (409)
When the operation of the main winding side hoisting machine is to be ended, the count after the main winding brake braking is performed based on the timer count for the purpose of determining whether the auxiliary winding side operation is possible. (410)
The above flowchart is an operation example on the main winding side of the present invention. The condition of the main winding inverter output relay ON in step 403 includes both of the conditions of the state of the main auxiliary switching MgSW only by the presence / absence of the relay ON in software. The operation of the auxiliary winding side hoisting machine is also the same.

図５は、本発明の過荷重時のフローチャート図である。主巻側、補巻側のどちらか一方で過荷重と判別した場合、主巻側、補巻側ともに巻上運転を禁止させる。   FIG. 5 is a flowchart of the present invention during overload. When an overload is determined on either the main winding side or the auxiliary winding side, the hoisting operation is prohibited on both the main winding side and the auxiliary winding side.

まず、主巻側巻上機が巻下運転か判別を行う。主巻側巻上機が巻下運転の場合はステップ５０３へ、主巻側巻上機が巻下運転でない場合はステップ５０２へ移る。（５０１）
次に主巻側巻上機が巻上禁止状態か判別を行う。主巻側巻上機が巻上禁止状態の場合はステップ５０７へ、主巻側巻上機が巻上禁止状態でない場合はステップ５０４へ移る。（５０２）そして、主巻側巻上機が巻下運転の場合、主巻側巻上機の巻上禁止クリア、補巻側巻上機の巻上禁止クリアを行い終了する。（５０３）
ステップ５０４にて主巻側巻上機が巻上禁止状態でない場合は、主巻側巻上機が巻上運転か判別を行う。主巻側巻上機が巻上運転の場合はステップ５０５へ、主巻側巻上機が巻上運転でない場合は終了する。（５０４）
ステップ５０５では、主巻側巻上機が過荷重設定電流値以上か判別を行う。主巻側巻上機が過荷重設定電流値以上の場合はステップ５０７へ、主巻側巻上機が過荷重設定電流値以上でない場合はステップ５０６へいく。（５０５）
つづいて、ステップ５０６で、主巻側巻上機が過荷重設定スベリ以上か判別を行う。主巻側巻上機が過荷重設定スベリ値以上だった場合はステップ５０７へ、主巻側巻上機が過荷重設定スベリ以上でない場合は終了する。（５０６）
ステップ５０７では、主巻側、補巻側巻上機をともに巻上運転禁止状態にして終了する。（５０７）以上のフローチャートが本発明の主巻側の過荷重時の実施例となる。ここでは、主巻側巻上機の動作を主として説明したが、補巻側の動作も同様である。 First, it is determined whether the main winding side hoisting machine is in the lowering operation. If the main winding side hoisting machine is in the lowering operation, the process proceeds to step 503. If the main hoisting side hoisting machine is not in the lowering operation, the process proceeds to step 502. (501)
Next, it is determined whether or not the main winding side hoisting machine is in a hoisting prohibited state. When the main winding side hoisting machine is in the hoisting prohibition state, the process proceeds to step 507, and when the main winding side hoisting machine is not in the hoisting prohibition state, the process proceeds to step 504. (502) Then, when the main winding side hoisting machine is in the lowering operation, clearing the hoisting prohibition of the main winding side hoisting machine and clearing the hoisting prohibition of the auxiliary winding side hoisting machine are completed. (503)
If it is determined in step 504 that the main winding side hoisting machine is not in the hoisting prohibition state, it is determined whether the main winding side hoisting machine is in the hoisting operation. If the main winding side hoisting machine is in the hoisting operation, the process proceeds to step 505. If the main hoisting side hoisting machine is not in the hoisting operation, the process ends. (504)
In step 505, it is determined whether the main winding side hoisting machine is equal to or greater than the overload set current value. If the main winding side hoisting machine is not less than the overload set current value, the process goes to step 507. If the main winding side hoisting machine is not the overload set current value or more, the process goes to step 506. (505)
Subsequently, in step 506, it is determined whether the main winding side hoisting machine is over the overload setting slip. If the main winding side hoisting machine is not less than the overload setting slip value, the process proceeds to step 507. If the main winding side hoisting machine is not the overload setting slip or more, the process ends. (506)
In step 507, both the main winding side and the auxiliary winding side hoisting machines are set in the hoist operation prohibited state, and the process ends. (507) The above flowchart is an embodiment of the present invention when the main winding is overloaded. Although the operation of the main winding side hoisting machine has been mainly described here, the operation on the auxiliary winding side is the same.

図６は、本発明の商用切替図である。本発明ではインバータが故障した場合、主巻・補巻ともに運転が出来なくなってしまう。しかし、図６のように配線変更を行うことで主巻側を商用機へ変更可能である。   FIG. 6 is a commercial switching diagram of the present invention. In the present invention, when the inverter breaks down, both the main winding and the auxiliary winding cannot be operated. However, the main winding side can be changed to a commercial machine by changing the wiring as shown in FIG.

図３と比較すると、図６では電源線とモータ線の配線変更と操作入力の商用入力のみである。図３で、主巻/補巻切替用マグネットスイッチ２８として使用していたものを、主巻上/下切替用マグネットスイッチ３３へと変更させることで商用運転可能となる。   Compared with FIG. 3, in FIG. 6, only the power input line and the motor line wiring change and the commercial input for operation input are provided. In FIG. 3, commercial operation is possible by changing the main winding / auxiliary winding switching magnet switch 28 to the main winding up / down switching magnet switch 33.

図７は、本発明の商用時の運転フローチャート図である。まず、商用信号入力有か判別を行う。商用信号入力有の場合７０２へ、商用信号入力有がない場合終了する。（７０１）
主巻側巻上機の巻上操作入力有か判別を行う。主巻側巻上機の巻上操作入力有の場合はステップ７０２へ、主巻側巻上機の巻上操作入力がない場合はステップ７０４へ移る。（７０２）
主巻側巻上機の巻上操作入力有だった場合、主巻側巻上機のブレーキ解放、巻上リレーＯＮを行い終了する。（７０３）
ステップ７０２で主巻側巻上機の巻上操作入力がない場合は、主巻側巻上機の巻下操作入力有か判別を行う。主巻側巻上機の巻下操作入力有の場合はステップ７０５へ、主巻側巻上機の巻下操作入力がない場合はステップ７０６へ移る。（７０４）
主巻側巻上機の巻下操作入力有だった場合、主巻側巻上機のブレーキ解放、巻下リレーＯＮを行い終了する。（７０５）
主巻側巻上機の巻上、巻下操作入力が無い場合、主巻側巻上機のブレーキ制動、巻上リレーＯＦＦ、巻下リレーＯＦＦを行い終了する。（７０６）
本実施例にかかる発明では、１つの制御部により主巻側、補巻側の両方を制御することで制御構成の簡略化、メンテナンス性の向上が可能である。また、１つの制御部により主巻側、補巻側の動作を制御することで、主巻側、補巻側両方の過荷重判別を行うことができ、主巻側、補巻側のどちらかが過荷重であった場合、主巻側の巻上動作、補巻側の巻上動作の両方を行わないようにすることが可能となる。また、１つの制御部により主巻側、補巻側の両方を制御することでインバータと回生抵抗または、その他の回生処理手段（回生コンバータや蓄電池など）の削減により制御構成のコストダウンが可能である。また、１つの制御部により主巻側、補巻側の両方の制御を行うため、制御部のインバータが故障した場合、主巻側・補巻側の両方が動作できなくなってしまう。しかし、本発明によれば、主巻側、補巻側のどちらかのみであれば、簡易的な配線変更と制御基板の設定を行うことで商用機として稼動することが可能である。
よって、構成の簡略化、メンテナンス性の向上、コストダウンを実現可能とする補巻付電動巻上機を提供することができる。 FIG. 7 is an operation flowchart of the present invention during commercial use. First, it is determined whether a commercial signal is input. If commercial signal input is present, the process advances to step 702. If there is no commercial signal input, the process is terminated. (701)
It is determined whether or not there is a hoisting operation input for the main winding side hoisting machine. If the main winding side hoisting machine has a hoisting operation input, the process proceeds to step 702. If the main hoisting side hoisting machine has no hoisting operation input, the process proceeds to step 704. (702)
If there is a hoisting operation input for the main winding side hoisting machine, the brake release of the main hoisting side hoisting machine and the hoisting relay are turned on and the process ends. (703)
If there is no hoisting operation input for the main winding side hoisting machine in step 702, it is determined whether there is an input for lowering operation of the main hoisting side hoisting machine. If the main winding side hoisting machine has a lowering operation input, the process proceeds to step 705. If there is no lowering operation input to the main winding side hoisting machine, the process proceeds to step 706. (704)
When the main winding side hoisting machine has a lowering operation input, the main hoisting side hoist is released and the lowering relay is turned on. (705)
If there is no input for hoisting / lowering operation of the main winding side hoisting machine, the brake braking, hoisting relay OFF, and lowering relay OFF of the main hoisting side hoisting machine are performed and the process is terminated. (706)
In the invention according to the present embodiment, it is possible to simplify the control configuration and improve the maintainability by controlling both the main winding side and the auxiliary winding side with one control unit. In addition, by controlling the operation of the main winding side and the auxiliary winding side by one control unit, it is possible to perform overload determination on both the main winding side and the auxiliary winding side, and either the main winding side or the auxiliary winding side can be performed. When is overloaded, it is possible not to perform both the winding operation on the main winding side and the winding operation on the auxiliary winding side. Also, by controlling both the main winding side and the auxiliary winding side with one control unit, the cost of the control configuration can be reduced by reducing the inverter and regenerative resistance or other regenerative processing means (regenerative converter, storage battery, etc.) is there. Further, since both the main winding side and the auxiliary winding side are controlled by one control unit, when the inverter of the control unit fails, both the main winding side and the auxiliary winding side cannot be operated. However, according to the present invention, as long as only one of the main winding side and the auxiliary winding side is used, it is possible to operate as a commercial machine by simply changing the wiring and setting the control board.
Therefore, it is possible to provide an auxiliary winding electric hoist capable of realizing a simplified configuration, improved maintainability, and cost reduction.
