Description
本發明係與數控工具機有關;特別是指一種工具機智能管理系統及其管理方法。 The invention relates to a numerical control machine tool; in particular, it refers to a machine tool intelligent management system and a management method thereof.
已知的數控工具機(Computerized Numerical Control,CNC)是指由電腦扮演整合控制的角色來實現電腦輔助設計(Computer Aided Design,CAD)及電腦輔助製造(Computer Aided Manufacture,CAM),並進一步地透過事先編輯的精確指令以自動進行各類切削的工具機。 The known numerical control machine tool (Computerized Numerical Control, CNC) means that the computer plays the role of integrated control to realize Computer Aided Design (CAD) and Computer Aided Manufacture (CAM), and further through A machine tool that uses pre-edited precise instructions to automatically perform various types of cutting.
前述精確指令係指將加工程式指令輸入數控系統之記憶體後,經由電腦編譯計算,透過位移控制系統,將資訊傳至驅動器以驅動馬達之過程,來切削加工所設計之零件,前述加工程式指令包含移動指令及其他加工過程中需使用到的輔助指令,所述輔助指令包含由位址碼(英文字母)及兩個數字所組成具有某種意義的動作或功能的機能指令,常見的機能指令包括有G機能(準備機能)、M機能(輔助機能)、T機能(刀具機能)等。 The aforementioned precise instructions refer to the process of inputting machining program instructions into the memory of the numerical control system, compiling and calculating by computer, and transmitting the information to the drive to drive the motor through the displacement control system to cut the designed part. The aforementioned machining program instructions Contains movement instructions and other auxiliary instructions that need to be used in the processing process. The auxiliary instructions include functional instructions with a certain meaning of actions or functions composed of address codes (English letters) and two numbers, common functional instructions Including G function (preparation function), M function (auxiliary function), T function (tool function) and so on.
已知數控工具機的應用實務上,從業人員先是在加工車間(Processing workshop)內對切削加工所需使用的各類刀具進行多項檢測及校正,且對檢測及校正後的刀具以手寫或是紙質條碼方式進行刀號編寫及分類管理,爾後再將檢測及校正後的刀具放置在刀具推車上以 便帶至加工現場。從業人員於加工現場再依據加工程式指令而將刀具推車上的刀具逐一擺放於數控工具機之刀庫上編列有刀號的置刀座中,以加工程式指令當中的「T15」為例,即表示從加工車間帶到加工現場且編號第15號的刀具應該被放置在刀庫編列有15號的置刀座,至此使得數控工具機在執行加工程式指令時,能正確取用刀具來對待加工物進行切削加工。 In the application practice of known CNC machine tools, practitioners first perform multiple inspections and corrections in the processing workshop (Processing workshop) for various types of tools required for cutting processing, and use handwriting or paper for the detected and corrected tools. Tool number programming and classification management are carried out by bar code, and then the detected and calibrated tools are placed on the tool cart for Take it to the processing site. At the processing site, the practitioners place the tools on the tool cart one by one in the tool holders with the tool numbers on the tool magazine of the CNC machine tool according to the processing program instructions. Take "T15" in the processing program instructions as an example. , Which means that the tool with No. 15 brought from the processing workshop to the processing site should be placed in the tool holder with No. 15 in the tool magazine, so that the CNC machine tool can correctly take the tool when executing the processing program instructions. Cut the workpiece to be processed.
然而在實務中,以手寫或是紙質條碼方式對刀具進行刀號編寫及分類管理的方式,存在著手寫辨識不易或是書寫錯誤的可能,而紙質條碼在油污環境下容易污損,因此現有以手寫或是紙質條碼方式對刀具進行刀號編寫及分類管理的方式未臻完善。 However, in practice, there is a possibility that handwriting or paper bar codes are used to write tool numbers and classified management of knives. There is a possibility that handwriting recognition is not easy or writing errors, and paper bar codes are easy to be stained in an oily environment. Therefore, the existing The way of writing tool numbers and sorting management of tools by handwriting or paper bar codes is not perfect.
另外,從業人員在將刀具自刀具推車上取出並放置於刀庫之置刀座的過程中,若有不察而導致刀具位置錯放,例如在刀庫編列15號的置刀座中錯放為經過檢測及校正且編為第14號的刀具,當錯誤未被發現並進入加工程序時,刀庫依據加工程式指令而運轉並使其編列15號的置刀座連同結合其上的第14號刀具一起抵達取刀位置之際,錯誤的第14號刀具將被取用,此情形輕則造成切削後的工件尺寸不符合加工需求而被棄置,重則發生刀具不當碰撞待加工物導致刀具或待加工物崩裂而需要停機以排除問題,如此將嚴重延看加工時程。
In addition, during the process of taking the tools out of the tool cart and placing them in the tool holder of the tool magazine, if the practitioner does not observe it, the position of the tool may be misplaced, for example, in the tool holder of No. 15 in the tool magazine. Put it as the tool that has been tested and corrected and is numbered 14. When the error is not found and enters the processing program, the tool magazine will operate according to the processing program instructions and make it list the
有鑑於此,本發明之目的在於提供一種工具機智能管理方法,係可對刀具進行有效的編列及管理,並可確保刀具能正確地被選用來進行加工使用。 In view of this, the purpose of the present invention is to provide an intelligent management method for machine tools, which can effectively arrange and manage the tools and ensure that the tools can be correctly selected for processing and use.
緣以達成上述目的,本發明提供的一種工具機智能管理系統包括具有主軸、刀庫及控制器的數控工具機,主軸一端裝設刀具,刀庫容納多數個刀具,控制器內建加工程式指令;另外,多數個電子標籤分別附隨於一個對應的刀具,且每一個電子標籤具有對應該刀具的刀具參數,一讀取器以非接觸方式接收讀取範圍內之刀具上的電子標籤的刀具參數。 In order to achieve the above objective, the present invention provides a machine tool intelligent management system including a CNC machine tool with a spindle, a tool magazine and a controller. One end of the spindle is equipped with a tool, the tool magazine contains a plurality of tools, and the controller has built-in machining program instructions. ; In addition, most of the electronic tags are attached to a corresponding tool, and each electronic tag has the tool parameters corresponding to the tool, and a reader receives the tool of the electronic tag on the tool within the reading range in a non-contact manner parameter.
本發明之智能管理方法即是先對多數個刀具各別進行檢測,並將檢測獲得的刀具參數儲存至一對應的電子標籤中,所述刀具參數包括不重複的加工刀號;接著將附隨有電子標籤的刀具擺放於刀庫中;再依據加工程式指令控制刀庫運轉,且依據加工程式指令當中的執行刀號而將選定的刀具運送至取刀位置;之後讀取位於取刀位置之刀具上所附隨電子標籤的刀具參數並透過比對所讀取刀具參數當中的加工刀號與加工程式指令當中的執行刀號是否相符,若比對為不相符時該控制器發出控制指令。 The intelligent management method of the present invention is to first detect a large number of tools individually, and store the detected tool parameters in a corresponding electronic tag. The tool parameters include non-repetitive machining tool numbers; The tools with electronic tags are placed in the tool magazine; the operation of the tool magazine is controlled according to the machining program instructions, and the selected tool is transported to the tool picking position according to the executed tool number in the machining program instructions; then it is read in the tool picking position The tool parameters of the electronic tag attached to the tool and compare whether the machining tool number in the tool parameters read is consistent with the execution tool number in the machining program command. If the comparison is not consistent, the controller will issue a control command .
在另一種的智能管理方法中,同樣先對刀具各別進行檢測並將檢測的刀具參數儲存至電子標籤中,所述刀具參數包括不重複的加工刀號;接著將附隨有電子標籤的刀具擺放於刀庫中;在讀取過各個刀具上的電子標籤後,在控制器中儲存與加工程式指令當中的執行刀號相連結的加工刀號;而取刀機構依據加工程式指令當中的執行刀號抓取位於該刀庫中之加工刀號與該執行刀號資訊連結的刀具。 In another intelligent management method, the tools are also detected individually and the detected tool parameters are stored in an electronic tag. The tool parameters include non-repetitive machining tool numbers; then the tools attached with the electronic tag Placed in the tool magazine; after reading the electronic tags on each tool, the processing tool number linked to the executed tool number in the processing program command is stored in the controller; and the tool fetching mechanism is based on the processing program command The execution tool number grabs the tool whose machining tool number is located in the tool magazine and the information of the execution tool number is linked.

本發明之工具機智能管理系統及管理方法係可對加工使用的刀具進行有效的編列與管理,並可確保刀具能正確地被選用以預防不當的後續程序發生,所述不當的後續程序例如是使用錯誤的刀具而為加工,又或者是發生刀具不當碰撞待加工物之情事。為能更清楚地說明本發明,茲舉較佳實施例並配合圖式詳細說明如後。 The machine tool intelligent management system and management method of the present invention can effectively arrange and manage the tools used for processing, and can ensure that the tools can be selected correctly to prevent improper follow-up procedures, such as The wrong tool is used for processing, or the tool improperly collides with the object to be processed. In order to explain the present invention more clearly, the preferred embodiments are described in detail in conjunction with the drawings as follows.
請參閱圖1所示,本發明第一較佳實施例之工具機智能管理方法主要包括檢測刀具S1、儲存刀具信息S2、刀具放置S3、刀具信息讀取S4以及比對信息S5等步驟,以下請再配合圖2至圖5所示,茲就各個步驟及實現該步驟中所需使用的器材設備說明如後。 Please refer to FIG. 1, the intelligent management method for machine tools of the first preferred embodiment of the present invention mainly includes the steps of detecting tool S1, storing tool information S2, tool placement S3, tool information reading S4, and comparing information S5. The following Please cooperate with the diagrams shown in Figure 2 to Figure 5. Here is the description of each step and the equipment and equipment required to achieve this step.
在檢測刀具S1方面:由於工具機在加工過程中經常需要使用到多種不同種類、規格的刀具,因此從業人員必須就加工過程當中需要使用到的刀具1預做準備,包括對刀具1進行各項量測及設定。實務中常見用於檢測刀具1的儀器例如對刀儀2(tool setting device),量測的項目包括但不限於刀長量測、刀徑量測,而設定則是對量測後的結果做進一步的調整,例如刀長補正、刀具歸零設定、刀具偏置值設定等,前述刀具的量測及設定結果以參數方式被儲存於電腦3中。須說明的是,前述檢測作業中的刀具1經常是以安裝至刀把4而來進行檢測的;另外,刀具1的檢測作業常見施作於加工車間,所述加工車間係指依據任務需求而在工作現場規劃出特定區域,本實施例的加工車間指的是內部儲放有多數刀具以及相關檢測儀器的場所。
In terms of detecting tool S1: Since the machine tool often needs to use a variety of different types and specifications of tools during the machining process, the practitioner must make pre-preparation for the
在儲存刀具信息S2方面:從業人員在加工車間內透過電腦3及無線射頻識別系統(Radio Frequency Identification system,RFID system)當中的發送器5(Transmitter)與天線(Antenna)(圖未示)而將上述對刀具1進行檢測獲得並儲存在電腦3中的刀具參數以非接觸方式發送至以讀寫式射頻識別標籤為例的電子標籤6內並予以儲存,所述刀具參數包括刀具規格、切削參數及轉速參數等,以及具有不重複的加工刀號,所述電子標籤6透過結合於刀把4的方式而與一對應的刀具1相附隨,更具體的說,每一個電子標籤6內所儲存的刀具信息正是所依附對象刀具1的檢測結果,且每一個電子標籤6因具有不重複的加工刀號而具備識別度。
In terms of storing tool information S2: Practitioners use the computer 3 and the transmitter 5 (Transmitter) and antenna (Antenna) (not shown in the figure) in the computer 3 and the radio frequency identification system (Radio Frequency Identification System, RFID system) in the processing workshop. The above-mentioned tool parameters obtained by detecting the
在刀具放置S3方面:當從業人員在加工車間內完成加工所需刀具的前置準備之後,應將刀具1連同其上的刀把4一起擺放至數控工具機7之刀庫7A的置刀座7B中,即按照置刀座7B上的編號而將具有對應
加工刀號的刀具1放入置刀座7B中。如圖5所示的刀庫7A盤面上沿著逆時針方向依序標記有數字「1」至數字「21」,即表示該刀庫7A可供21把具有不同規格的刀具1放置,當所有的刀具皆已上架完成即表示可以進入加工程序。前述刀庫7A可以是圓盤式刀庫或者是能夠容納更多刀具的鏈條式刀庫。
In terms of tool placement S3: After the practitioner completes the pre-preparation of the tools required for processing in the machining workshop, the
在刀具信息讀取S4方面:當從業人員透過數控工具機7之控制器7C的操作面板7D而來開啟加工程序時,主軸7E一端(底端)所裝設的刀具1將依據控制器7C內建的加工程式指令而開始高速旋轉及位移,據以對固定在工作臺7F上的待加工物8進行加工。由於一個待加工物8通常需要經過銑、削、鑽孔或是螺紋製作等多道的加工程序方能製得成品,因此主軸7E一端所裝設的刀具1是依據加工程式指令當中所編譯的執行刀號而被替換,例如當程式執行至編譯的執行刀號「T15」時,即表示下一個加工程序當中的主軸7E一端應裝設選自位於刀庫7A上編號「15」位置的刀具1,於此同時,刀庫7A將被控制運轉並將選定的刀具運送至取刀位置,該被選定的刀具在被抓取之前,裝設在數控工具機7內的讀取器9將以非接觸方式接收讀取範圍內之刀具1上所附隨電子標籤6的刀具參數。以圖5當中的刀庫7A為例,其取刀位置係位於盤面的最下緣處,而讀取器9的讀取範圍係指讀取器9至位於取刀位置之刀具1的距離。
In terms of tool information reading S4: when the practitioner starts the machining program through the
在比對信息S5方面:控制器7C將自動地對讀取器9所接收刀具參數當中的加工刀號,與內建加工程式指令當中的執行刀號進行比對判讀,並在比對加工刀號與執行刀號為不相符時發出控制指令,反之,若比對的加工刀號與執行刀號相符時,則控制器7C依加工程式指令繼續執行後續的加工程序。舉例來說,當加工程式指令進行至編譯的執行刀
號「T15」時,刀庫7A即依加工程式指令而被控制運轉至其盤面上所標記數字「15」的置刀座7B連同放置在該置刀座7B中的刀具1一同來到取刀位置,然而讀取器9接收位在取刀位置之刀具1上所附隨電子標籤6內的刀具參數卻是包含「T14」的加工刀號時,控制器7C因比對發現有誤旋即發出控制指令,在一實施例中,前述控制指令可以是停機的指令,藉以避免實際上編為「T14」的刀具卻被誤以為是編號「T15」的刀具而被用來切削加工導致切削後的工件尺寸不符合期待或是不當地與待加工物發生碰撞。前述情形的發生肇因於從業人員在將刀具自加工車間移出並放置於刀庫之置刀座的過程中,因不察導致刀具位置錯放所致。另說明的是,加工刀號與執行刀號的比對不限於是數字的比對,也可以是以其他代碼方式用來比對。
In terms of comparison information S5: the
是以,本發明透過讀取器9接收取刀位置之刀具1上所附隨電子標籤6內的刀具參數,以及控制器7C兼具的比對功能,在選定的刀具被抓取之前及時辨識出刀具位置是否有錯放,進一步地確保刀具能正確地被選用來進行加工使用。另外,刀具的識別編號係透過電子標籤6具有不重複的加工刀號而達成,改善已知以手寫或是紙質條碼方式對刀具進行刀號編寫及分類管理所帶來的不便。
Therefore, the present invention receives the tool parameters in the
再說明的是,控制器7C除了可發出控制指令之外,更可被賦予將比對發現錯誤的信息即時顯示在操作面板7D的顯示屏幕7G上,或者以發出聲響或是亮光的方式來提醒從業人員注意的功能,以便從業人員能及時排除問題。甚者,控制器7C亦可透過行動應用程式(mobile application)傳送即時信息予具有可讀取該信息之電子裝置的特定相對人,以便監控。
It should be noted that, in addition to issuing control commands, the
上述實施例中的控制指令係用以控制停機,然而在其他的實施例中,控制指令可以不用來控制停機而是作為其他的控制使用,例如當控制指令包含有與加工程式指令當中的執行刀號相符的加工刀號時,則可用以控制刀庫7A運轉並將正確的刀具1帶至取刀位置,為了達成前述目的,本發明提供第二較佳實施例的工具機智能管理方法係在上述第一較佳實施例之方法的架構下予以調整,請參閱圖6所示,其中在刀具放置S3之後、刀具信息讀取S4之前,操控刀庫7A以分度方式運轉一圈,讀取器9逐一接收通過取刀位置之所有刀具1上所附隨電子標籤6的刀具參數並將之傳遞至控制器7C,前述刀具參數包含不重複的加工刀號,於此同時,控制器7C把置刀座7B上的編號與存放在該置刀座7B中之刀具1的加工刀號予以連結並記錄,舉例而言,當刀庫7A運轉至使其置刀座7B的編號「15」來到取刀位置時,讀取器9所接收電子標籤6當中的加工刀號在正確的情況下應該是「T15」,控制器7C即把置刀座7B編號「15」與刀具1的加工刀號「T15」產生連結與記錄,此步驟定義為刀具與置刀座信息收集S3-1。
The control command in the above embodiment is used to control the shutdown. However, in other embodiments, the control command may not be used to control the shutdown but used for other control. For example, when the control command includes the execution tool in the machining program command When the machining tool number matches the tool number, it can be used to control the operation of the
當從業人員在完成刀具與置刀座信息收集S3-1作業,且透過操作面板7D而來啟動數控工具機7以進行加工程序時,常態下的讀取器9接收位於取刀位置之刀具1上所附隨電子標籤6內的加工刀號應該與同樣位於取刀位置的置刀座7B編號相符,然而,若當從業人員在將刀具自加工車間移出並放置於刀庫之置刀座的過程中因不察導致刀具位置錯放時,將使得讀取器9接收到的加工刀號經控制器7C比對後發現與加工程式指令當中的執行刀號不相符,此時的控制器7C將自資料庫中查找正確的刀具被放置在第幾號的置刀座中,據此發出包含有與執行刀號相符的加工刀號的控制指令,並控制刀庫7A以最短的運轉行程而將正確的
刀具1運送至取刀位置,以便數控工具機7的主軸7E能夠取用正確的刀具,前述將正確刀具帶至取刀位置的步驟定義為換刀作業S6。至此,無須停機即能續行加工程序。
When the practitioner completes the S3-1 operation of collecting tool and tool holder information, and starts the
從上述各個實施例可知,本發明用以實現智能管理方法的管理系統至少包括數控工具機7、電子標籤6及讀取器9,其中數控工具機7尚且包括有主軸7E、刀庫7A及控制器7C;而管理系統若更包含有發送器5將使得管理方法更為完整。
It can be seen from the above various embodiments that the management system of the present invention for realizing the intelligent management method includes at least a
另外本發明再提供一種智能管理方法,請配合圖7所示,其係應用於包括有加工機10、刀庫11及取刀機構12的工具機系統中,其中加工機10包括主軸10a與控制器10b,主軸10a一端裝設有刀具1,控制器10b內建包含有執行刀號的加工程式指令;刀庫11獨立於加工機10之外且具有多數個置刀座11a可容納各式各樣的刀具,每個刀位具有不重複的編號;而取刀機構12依據加工程式指令自刀庫11中抓取適當的刀具。
In addition, the present invention further provides an intelligent management method, please cooperate with FIG. 7, which is applied to a machine tool system including a
請參閱圖8所示,該方法依序包括檢測刀具S1、儲存刀具信息S2、刀具放置S3、刀具信息讀取S7、刀具信息連結與儲存S8及取刀S9等步驟,其中步驟S1及步驟S2與上述實施例相同,而步驟S3當中的刀具1係被放置在屬於大型儲刀結構體的刀庫11的不同置刀座11a中。

在刀具信息連結與儲存S8方面:當讀取器9完成每一個刀具信息讀取的同時,控制器10b將自動地把刀位、刀具參數當中的加工刀號及加工程式指令當中的執行刀號做資訊連結並予以儲存。
In terms of tool information connection and storage S8: When the
在取刀S9方面:取刀機構12接受來自控制器10b的加工程式指令當中的執行刀號,進一步地自動抓取位於刀庫11中之加工刀號與執行刀號資訊連結的刀具1。必須說明的是,在此步驟S9中,取刀機構12的取刀方式是以刀具上之電子標籤中的加工刀號為依據,而非以刀位為準,因此可以快速地找到刀具位置以減縮時間。取刀機構12並將取得的刀具帶至加工機10以續行後續的加工程序,而在加工機10包括有換刀臂10c時,取刀機構12是把刀具交給換刀臂10c,換刀臂10c再將之與主軸10a上的刀具交換,自主軸10c上取下的刀具則再透過換刀臂10c以及取刀機構12而被放置到刀庫11的空置刀位中。
In terms of tool retrieval S9: the
爾後,重啟步驟S7、步驟S8,以待下一次步驟S9的執行。至此,亦能避免從業人員因不察而將刀具錯放在非正確位置處所衍生加工錯誤的情形發生。另說明的是,以本實施例技術為基礎時可同時應用於多部工具機及多組刀庫同時使用。 Thereafter, step S7 and step S8 are restarted to wait for the next execution of step S9. At this point, it can also avoid the occurrence of processing errors caused by the practitioners who place the tool in an incorrect position due to inadvertence. It should also be noted that, based on the technology of this embodiment, it can be applied to multiple machine tools and multiple tool magazines at the same time.
