工具機Machine Tools

發明領域Invention Field

本發明是有關於一種工具機。The present invention relates to a machine tool.

發明背景Invention Background

在工具機中，使複數個伺服馬達協調動作來進行工件的加工。一般而言，伺服馬達是藉由從一對一地對應的伺服放大器所供給的電流驅動。伺服馬達，即使在不使輸出軸位移的情況下，仍然會激磁，並調整輸出，以使旋轉位置與當時的目標位置一致。In machine tools, multiple servo motors are coordinated to process workpieces. Generally speaking, servo motors are driven by current supplied from a one-to-one corresponding servo amplifier. Even if the output shaft is not displaced, the servo motor is still excited and the output is adjusted so that the rotation position is consistent with the target position at that time.

如上述，通常工具機的伺服馬達是設為經常被激磁且消耗電力的狀態。例外地，為了防止發生停電時等進給軸衝撞(干擾到其他軸或可動極限)，已提案一種在偵測到異常時阻斷對伺服馬達的電力供給的技術(參照例如專利文獻1)。 先前技術文獻 專利文獻 As mentioned above, the servo motor of a machine tool is usually set to be constantly excited and consume power. Exceptionally, in order to prevent the feed axis from colliding (interfering with other axes or movable limits) when a power outage occurs, a technology has been proposed to cut off the power supply to the servo motor when an abnormality is detected (see, for example, Patent Document 1).

Specific examples of the driven components 41, 42, 43, 44, 45 include a tool chuck, a workpiece holding table, a door panel, etc. Furthermore, the driven components 41, 42, 43, 44, 45 may also include other servomotors 11, 12, 13, 14 for multi-axis positioning.

In addition, the state sensors 51, 52, 53, 54, 55, 56 may also be sensors for confirming that there is no person or object in a specific space. The state sensors 51, 52, 53, 54, 55, 56 may be, for example, photoelectric tubes, limit switches, etc.

控制裝置60可藉由例如具備記憶體、處理器(CPU)、輸出入介面、顯示器等，且執行適當的控制程式之一個或複數個電腦裝置來實現。具體而言，控制裝置60可為例如數值控制裝置、可程式邏輯控制器、個人電腦等。控制裝置60具備：指令值生成部61、安全資訊取得部62、停止控制部63、重新開始控制部64、及有效化設定部65。該等控制裝置60的各構成要素，亦可是將控制裝置60的功能予以分類而成之構成要素，無法在實體構成及程式構成上明確地區分亦可。The control device 60 can be implemented by one or more computer devices that have a memory, a processor (CPU), an input/output interface, a display, etc., and execute an appropriate control program. Specifically, the control device 60 can be, for example, a numerical control device, a programmable logic controller, a personal computer, etc. The control device 60 has: an instruction value generation unit 61, a safety information acquisition unit 62, a stop control unit 63, a restart control unit 64, and a validation setting unit 65. The various components of the control device 60 can also be components that classify the functions of the control device 60, and it is not necessary to clearly distinguish between the physical structure and the program structure.

指令值生成部61根據加工程式，來生成輸入於伺服放大器21、22、23、24的指令值。指令值生成部61可構成為考慮表示伺服馬達11、12、13、14的實際的速度的反饋訊號，來補正輸入於伺服放大器21、22、23、24的指令值。The command value generating unit 61 generates command values input to the servo amplifiers 21, 22, 23, 24 according to the processing formula. The command value generating unit 61 may be configured to correct the command values input to the servo amplifiers 21, 22, 23, 24 in consideration of feedback signals indicating actual speeds of the servo motors 11, 12, 13, 14.

安全資訊取得部62取得表示對於伺服馬達11、12、13、14的激磁停止的安全性之一個或複數個安全資訊。安全資訊分別表示一個或複數個伺服馬達11、12、13、14的安全性，複數個安全資訊亦可表示同一伺服馬達11、12、13、14的安全性。複數個安全資訊表示同一伺服馬達11、12、13、14的安全性的情況下，在全部的安全資訊成為表示安全之值的情況下，可視為即使停止相對應的伺服馬達11、12、13、14的激磁，仍可確保安全。「對於激磁停止的安全性」意指：在發生了伴隨抵抗重力的扭矩的喪失之被驅動構件41、42、43、44的下降、伴隨制動力的喪失之被驅動構件41、42、43、44的過衝等的情況下，仍認為不會產生危害。安全資訊較理想的是包含狀態感測器51、52、53、54、55、56的檢測值，亦可進一步包含伺服馬達11、12、13、14的編碼器的資訊、具有剎車的伺服馬達11、12、13、14的剎車動作資訊、使用者操作的手動開關的狀態等。The safety information acquisition unit 62 acquires one or more safety information indicating the safety of stopping the excitation of the servo motors 11, 12, 13, 14. The safety information indicates the safety of one or more servo motors 11, 12, 13, 14, respectively, and the plurality of safety information may indicate the safety of the same servo motor 11, 12, 13, 14. When the plurality of safety information indicates the safety of the same servo motor 11, 12, 13, 14, when all the safety information becomes a value indicating safety, it can be considered that safety can be ensured even if the excitation of the corresponding servo motors 11, 12, 13, 14 is stopped. "Safety for excitation stop" means that no harm will occur even if the driven components 41, 42, 43, 44 fall due to the loss of torque against gravity, or the driven components 41, 42, 43, 44 overshoot due to the loss of braking force, etc. The safety information preferably includes the detection values of the state sensors 51, 52, 53, 54, 55, 56, and may further include the information of the encoder of the servo motor 11, 12, 13, 14, the brake action information of the servo motor 11, 12, 13, 14 with brakes, the state of the manual switch operated by the user, etc.

停止控制部63在加工程式的非執行時，使安全資訊表示安全的伺服馬達11、12、13、14的激磁停止。亦即，停止控制部63對伺服放大器21、22、23、24當中，驅動根據安全資訊來判斷為即使停止激磁仍為安全的伺服馬達11、12、13、14的伺服放大器，使激磁電流的輸出停止。藉此，可抑制未執行加工程式的期間的伺服馬達11、12、13、14的電力消耗。The stop control unit 63 stops the excitation of the servo motors 11, 12, 13, and 14, which the safety information indicates are safe, when the machining formula is not being executed. That is, the stop control unit 63 drives the servo amplifiers 11, 12, 13, and 14, which are determined to be safe even if the excitation is stopped based on the safety information, among the servo amplifiers 21, 22, 23, and 24, to stop the output of the excitation current. In this way, the power consumption of the servo motors 11, 12, 13, and 14 during the period when the machining formula is not being executed can be suppressed.

較理想的是，停止控制部63在停止伺服馬達11、12、13、14的激磁時，顯示停止激磁之情形，以便可以讓使用者確認激磁的停止。Preferably, when the excitation of the servo motors 11, 12, 13, and 14 is stopped, the stop control unit 63 displays the stop of the excitation so that the user can confirm the stop of the excitation.

停止控制部63不僅對驅動伺服馬達11、12、13、14的伺服放大器21、22、23、24使激磁電流的輸出停止，亦可阻斷對伺服放大器21、22、23、24之電力的供給，亦即斷開一次斷路器211、221、231、241。藉此，即可進一步抑制消耗電力。The stop control unit 63 not only stops the output of the exciting current to the servo amplifiers 21, 22, 23, 24 driving the servo motors 11, 12, 13, 14, but also blocks the supply of power to the servo amplifiers 21, 22, 23, 24, that is, disconnects the primary circuit breakers 211, 221, 231, 241. In this way, the power consumption can be further suppressed.

停止控制部63亦可使驅動安全資訊表示安全的伺服馬達11、12、13、14的伺服放大器21、22、23、24的通訊停止或使通訊速度降低。藉此，亦可抑制伺服放大器21、22、23、24的通訊用的電力。The stop control unit 63 may also stop or reduce the communication speed of the servo amplifiers 21, 22, 23, and 24 driving the servo motors 11, 12, 13, and 14 whose safety information indicates safety. In this way, the power used for communication of the servo amplifiers 21, 22, 23, and 24 may also be suppressed.

停止控制部63亦可與伺服馬達11、12、13、14的激磁停止同步地預先阻斷對已與該伺服馬達11、12、13、14建立連繫之附帶裝置30的電力供給。作為可與伺服馬達11、12、13、14同步來阻斷電力供給的裝置，可列舉顯示伺服馬達11、12、13、14的資訊的顯示裝置、用以提升伺服馬達11、12、13、14、被驅動構件41、42、43、44、45等的視覺辨識性的照明、將伺服馬達11、12、13、14冷卻的冷卻風扇等。The stop control unit 63 can also preliminarily block the power supply to the accessory device 30 that has established a connection with the servo motor 11, 12, 13, 14 in synchronization with the deactivation of the excitation of the servo motor 11, 12, 13, 14. As a device that can block the power supply in synchronization with the servo motor 11, 12, 13, 14, there can be listed a display device that displays information of the servo motor 11, 12, 13, 14, a lighting for improving the visual recognition of the servo motor 11, 12, 13, 14, the driven components 41, 42, 43, 44, 45, etc., a cooling fan that cools the servo motor 11, 12, 13, 14, etc.

重新開始控制部64在停止控制部63停止伺服馬達11、12、13、14的激磁的期間，監視狀態感測器51、52、53、54、55、56的檢測值。重新開始控制部64在根據狀態感測器51、52、53、54、55、56的檢測值，判斷伺服馬達11、12、13、14的激磁停止成為可能產生危害的狀態的情況下，會使停止控制部63重新開始伺服馬達11、12、13、14的激磁。The restart control unit 64 monitors the detection values of the state sensors 51, 52, 53, 54, 55, 56 while the stop control unit 63 stops the excitation of the servo motors 11, 12, 13, 14. When the restart control unit 64 determines that the stop of the excitation of the servo motors 11, 12, 13, 14 has become a state that may cause harm based on the detection values of the state sensors 51, 52, 53, 54, 55, 56, it causes the stop control unit 63 to restart the excitation of the servo motors 11, 12, 13, 14.

有效化設定部65按照外部訊號來將停止控制部63有效化或無效化。當停止控制部63停止伺服馬達11、12、13、14的激磁時，一旦對加工程式讓執行開始，由於有可能產生重新開始伺服馬達11、12、13、14的激磁用的等待時間，因此在加工程式的執行間隔短的情況下，可藉由例如來自管理電腦等的外部訊號將停止控制部63無效化，藉此防止運轉率的降低。The validation setting unit 65 validates or invalidates the stop control unit 63 according to an external signal. When the stop control unit 63 stops the excitation of the servo motors 11, 12, 13, and 14, once the processing program is started, a waiting time may be generated to restart the excitation of the servo motors 11, 12, 13, and 14. Therefore, when the processing program execution interval is short, the stop control unit 63 can be invalidated by an external signal from, for example, a management computer, thereby preventing the operating rate from being reduced.

如以上，由於工具機1具備未執行加工程式時停止伺服馬達11、12、13、14的激磁的停止控制部63，因此可以抑制藉由伺服馬達11、12、13、14的激磁所造成的消耗電力。As described above, since the machine tool 1 includes the stop control unit 63 that stops the excitation of the servo motors 11, 12, 13, 14 when the machining mode is not being executed, the power consumption caused by the excitation of the servo motors 11, 12, 13, 14 can be suppressed.
