基于PLC的物料分揀系統(tǒng)畢業(yè)設計外文翻譯

1、基于PLC的物料分揀系統(tǒng)畢業(yè)設計外文翻譯畢業(yè)設計外文文獻翻譯畢業(yè)設計題U基于PLC的物料分揀系統(tǒng)設II-翻譯題The Design of Material Choose System Based on PLC專 業(yè) 機械設計制造及其自動化姓名朱安樂班級A0916學號指導教師張曉機械與材料工程學院二0二年十二月譯文一：關于可編程控制器技術與未來發(fā)展?隨著時代的發(fā)展，當今的技術也日趨完善、競爭愈演愈烈；單幕人工的操作已不能滿足于LI前的制造業(yè)前景，也無法保證更高質量的要求和高新技術企業(yè) 的形象。人們在生產(chǎn)實踐中看到，自動化給人們帶來了極大的便利和產(chǎn)品質量上的 保證，同時也減輕了人員的勞動強度，減少

2、了人員上的編制.在許多復雜的生產(chǎn)過 程中難以實現(xiàn)的日標控制、整體優(yōu)化、最佳決策等，熟練的操作工、技術人員或 專家、管理者卻能夠容易判斷和操作,可以獲得滿意的效果.人工智能的研究LI標 正是利用計算機來實現(xiàn)、模擬這些智能行為，通過人腦與計算機協(xié)調工作，以人機 結合的模式,為解決十分復朵的問題尋找最佳的途徑。我們在各種場合看到了繼電器連接的控制，那已經(jīng)是時代的過去，如今的 繼電器只能作為低端的基層控制模塊或者簡單的設備中使用到;而PLC的出現(xiàn)也 成為了劃時代的主題，通過極其穩(wěn)定的硬件穿插靈活的軟件控制，使得自動化走 向了新的高潮。一個系統(tǒng)化的設ir?PLc程序的方法可以克服傳統(tǒng)程序生產(chǎn)控制系統(tǒng)的缺

3、 點，并且在一些工業(yè)應用總有很大的不同。自動控制系統(tǒng)是狀態(tài)模型用公式語言 或等價的語言描述的。公式描述對被控制的系統(tǒng)的行為提供一個精確的描述。可 以通過分析估訃看狀態(tài)模型是否達到想要的L1標。第二，為狀態(tài)模型的描述提供 結構描述，這個結構描述可以說明邏輯要求和如細節(jié)安全規(guī)則的限制。第三，好的 控制系統(tǒng)設計是對自動控制代碼生成有益的? 一種能夠產(chǎn)生可執(zhí)行的控制軟件 的能力，不同的邏輯控制器可以減少程序掃描時間和執(zhí)行那個時間。特別的，這個 主題與隨后的部分的是有關的。在現(xiàn)代制造業(yè)中，系統(tǒng)是用過程和結果的革新來描述的，并且因此不得不 改變系統(tǒng)性能以快速做出反應。因此，一個大的挑戰(zhàn)是提供技術以限制自動

4、控制 系統(tǒng)對變化需要和新機會的反應，所以，設計和操作知識可以實時的被再次利用, 在工業(yè)實踐中提供了一個重要的競爭面。PLC的最大特點在于：電氣工程師已不再電氣的硬件上花費太多的心計, 只要將按鈕開關或感應器的輸入點連接到PLC的輸入點上就能解決問題,通過輸 出點連接接觸器或繼電器來控制大功率的啟動設備,而小功率的輸出設備直接連 接就可以。在很多場合，單靠單機的控制是無法保證設備的順暢運行，而通過設備與 設備的信息交流達到我們想要的效果。比如在前包裝和后工序的檢測，我們就要 將包裝的信息反饋到檢測處，而檢測處的信息也要反饋到包裝來。這樣通過信息 共享來使得兩者之間鏈接起來,形成一個共體，從而使的

5、兩者間的配合更加的緊 密，在彼此間達到映影相揮的效果。PLC的數(shù)據(jù)傳送只是將內(nèi)部的數(shù)據(jù)傳送到對方的一塊連續(xù)的地址中，我們 把它稱為一個表,對方的PLC通過讀取表中的數(shù)據(jù)來進行操作。如果表中的數(shù)據(jù) 是一個一般設置的數(shù)據(jù)的話，那只是一般的數(shù)據(jù)傳送，比如今天的油價上升了，我 要把油價的價格傳送到所有的輸油機上，那就是數(shù)據(jù)的共享；而當表中的數(shù)據(jù)是 一段控制PLC的指令程序，那就很有難度了，比如你要控制一臺機器人來按你想 象的動作丄作，你會給它編制一段程序并以數(shù)據(jù)的形式發(fā)送過去。當你在看書的時候，你聽到有人敲門、你停下手上的事情、去打開門、并 同敲門者對話、這個時候電話響了、你示意接個電話、在接完電話后

6、、回過頭來 同敲門者繼續(xù)對話、對話完畢后、你再繼續(xù)看你的書，這種情況我們把它稱為中 斷,它具有權威性，也具有優(yōu)先性,PLC具備了這樣的功能。它的特點在于我們在 設備的操作過程中可能會遇到緊急的突發(fā)事件，我們要立刻的停下手上的工作, 去處理更重要的事情，這種情況是我們經(jīng)常所遇到的,PLC在去執(zhí)行緊急的任務 時，總會先保存LI前的狀態(tài)，比如程序的地址,CPU的累加器數(shù)據(jù)等，就像我們?nèi)?開門時要記下我們看的書在第兒頁了或者干脆作個記號，因為我們待會還要繼續(xù) 接著看后面的書。CPU總是按照我們的意愿去做應該做的事情，但你錯誤的給它 一件事情，它也會同樣的去做，這一點我們必須注意。通信對于個人自動單元是

7、很重要的。在過去的兒年里，我們聽到許多關于 生產(chǎn)自動化協(xié)議的事情，并且許多公司已經(jīng)加入大有成功希望的事業(yè)。然而，當一 個完整的生產(chǎn)自動化協(xié)議說明書沒有及時出現(xiàn)時許多公司都很失望。 Larry?Kotare?說:“現(xiàn)在，生產(chǎn)自動化協(xié)議仍然是生產(chǎn)中一個發(fā)展的對象，一個說 明書并不是最終的結果。例如，雖然當新的生產(chǎn)自動化協(xié)議?MAP3.0?版本使用之 時以MAP2. 1?版本為基礎的產(chǎn)品將會被汰，但是現(xiàn)在人們?nèi)匀粚a(chǎn)品用 于?MAP2. 1版。”曲于這些原因，許多?PLC廠家緊盯著MAP?的最新結果。如歐姆龍公司正在進行一個有關MAP?兼容性的項目。但是歐姆龍生產(chǎn)部門總經(jīng) 理?Frank?Newbo

8、rn說山于缺少一個固定的標準，歐姆龍的產(chǎn)品并不涉及 到?MAP。?由于工業(yè)PLC無論何時不可能廣泛的涉及到?MAP,生產(chǎn)廠家正在考慮專用 網(wǎng)絡。根據(jù)Sal?Probanzano?說法，用戶擔心如果他們廣泛的應用主產(chǎn)廠家將會 收回MAP,這樣將會留下一個不支持通信的交流框架。英文原文一:9PLC?technique?discussion?and?future?development9?Along?with?the?development?of?the?ages, ?the?technique?that?is ?nowadays?is?also?gradually?perfect, ?the?co

35、向工業(yè)控制的 簡單指令，形象直觀，是基于現(xiàn)場總線技術、完全開放，采用先進的軟硬件技術。 PLC控制具有結構簡單靈活、抗干擾能力強、安全可靠、安裝便利、故障率低、 維護簡單、大幅度節(jié)約使用成本的特點，能滿足各種中小規(guī)模過程控制、順序邏 輯控制和數(shù)據(jù)采集任務需求，已逐漸廣泛用于工業(yè)控制系統(tǒng)中，包括冶金、礦業(yè)、 機械、輕工等領域,為工業(yè)自動化提供了有力的工具。控制工程近期對用于編程過程和機械控制的邏輯設備進行了一項調查，雖 然計算機和計算機技術已經(jīng)為各種控制提供了無限的控制可能，但是PLC仍然是 其中重要的一部分。在這次調查中，超過半數(shù)的人在未來的12個月中將擴大其PLC的投入。超過40%的人在未來

36、的投入不少于過去的12個月。PLC的應用范圍 十分廣泛。在這次300個人參與的調查中，大部分的PLC都用于機械控制,過程控 制緊隨其后，然后是運動控制、批量控制和診斷。大多數(shù)直接用于工廠級(54%), 用于OEM的為25%,兩者都是的為17%。?在工業(yè)生產(chǎn)流水線中，經(jīng)常要將傳動帶A上的物品搬至傳送帶B上。如果 直接人工從事這種重復性的勞動，枯燥、無味且勞動強度大，容易引起操作工人的 疲勞，出現(xiàn)錯誤。而采用氣動機械手按規(guī)定的動作和規(guī)律進行搬運，可以做到快 速、準確、方便,大大的減輕勞動強度，提高生產(chǎn)的自動化程度。氣動機械手這種 有規(guī)律的運動，采用PLC來進行控制，可以方便的實現(xiàn)。氣動手爪是訂前機

37、器手尤其是搬運、裝配類機器手在抓取技術中應用最普 遍的方式.它可實現(xiàn)雙向抓取.自行對中，而且重復精度高.抓取力恒定.并可方便 地配接各種夾具。氣動手爪是機器手與作業(yè)對象間的直接接口，仔細分析、選擇 好氣動手爪直接關系到機器手的工作性能。在實際運行中、手爪的夾持力應保證 大于所有靜態(tài)和動態(tài)力的總和。PLC的程序運行方式是循環(huán)掃描方式，而非順序 執(zhí)行方式，因此任何一個機械手在其條件滿足后即開始動作。各手之間是并行的。 機器手是多自山度的開式串聯(lián)結構在空間和時間中的動力學參數(shù)隨其位形而不 斷變化.系統(tǒng)要求的速度高控制范圍廣精度高，傳統(tǒng)的單自山度機構的控制技 術遠不能滿足這種控制對象好在氣動機器手多勾

38、點到點的多段定位控制，追求 LI標點的定位精度和多軸同時協(xié)凋有序運動控制，但較少要求高的軌跡精度，從 而簡化了對控制系統(tǒng)的要求。物料的搬運方式具有可抓可吸的多用途功能;氣動系統(tǒng)電磁換向閥采用匯 流板集裝方式，減少了占用空間;PLC控制具有單步、自動等多種工作方式。由于 氣壓傳動具有氣源使用方便、不污染環(huán)境、動作靈活迅速、工作安全可靠、操作 維修簡便以及適于在惡劣環(huán)境下工作等特點，因而在沖壓加工、注塑及壓鑄等有 毒或高溫環(huán)境下作業(yè)，機床上、下料，儀表及輕丄行業(yè)中小零件的輸送和自動裝配 等作業(yè)，食品包裝及輸送，電子產(chǎn)品輸送、自動插接,彈藥生產(chǎn)自動化等過程中被 廣泛應用。所以。氣壓傳動是一種易于推廣

39、普及的實現(xiàn)工業(yè)自動化的應用技術。 氣動系統(tǒng)的應用，引起了世界各國產(chǎn)業(yè)界的普遍重視。物料搬運系統(tǒng)III左右移動氣缸、復位進退氣缸、升降氣缸、夾手或真空吸 盤、物料塊、傳感器、圓柱導軌、支架、底座、微動開關等組成。夾手或真空吸 盤可以夾住或吸住物料塊，抓取物料的部分采用夾持式和吸附式兩種形式，選用 不同的形式，可分別完成工件的抓取和吸附，以適應不同種類的物料搬運。夾手采 用電磁鐵吸合與斷開方式夾持物料。夾手或吸盤在升降氣缸的作用下可以上下移 動;夾手或真空吸盤連同升降氣缸在左右移動氣缸的作用下沿著圓柱導軌可以左 右移動；在復位進退氣缸的作用下將物料塊送回原始位置，為下一個工作周期準 備，以實現(xiàn)循環(huán)

40、。此系統(tǒng)能夠實現(xiàn)物料在一個平面內(nèi)的搬運。操作面板安裝在電 控箱上，與實驗裝置主體是分離的。PLC可編程序控制器，電磁閥，真空發(fā)生器等 均放置在電控箱里。物料搬運系統(tǒng)具有左右移動、上下移動及對物料的夾緊和放松、推料進退 功能，在PLC控制下可實現(xiàn)單步、自動等多種工作方式。另外，物料被夾手搬運完 成以后，為滿足連續(xù)動作需要，還必須將此物料運送回原點位置，以供下次搬運需 要。系統(tǒng)可完成的各種工作方式如下。單步:可實現(xiàn)上升、下降、左移、右移、 夾緊、放松、推料進、推料退等八種點動操作;連續(xù):按下“啟動”按鈕后，夾手 從原點位置開始連續(xù)不斷地執(zhí)行搬運物料。物料搬運系統(tǒng)實現(xiàn)的動作：下降一抓 料一上升一右移

41、一再下降一松料一再上升一左移一推料進一推料退。在這個系統(tǒng) 中，我們只實現(xiàn)一個物料的循環(huán)動作，故在機械手回原點后，需將物料推回原來位 置。在PLC控制下可實現(xiàn)單動、連續(xù)動作工作方式。系統(tǒng)上電后,通過旋轉按扭 選擇是單動還是連動，如果是單動則執(zhí)行單動程序，否則執(zhí)行連動程序。單動工作 方式:利用按鈕對夾手每一動作單獨進行控制。連續(xù):按下啟動按鈕，夾手從原點 開始,按工序自動循環(huán)工作，直到按下停止按鈕，夾手在完成最后一個周期的工作 后，返回原點，自動停機?；赑LC控制的物料搬運系統(tǒng)能夠實現(xiàn)物料的自動循環(huán)搬運。此系統(tǒng)既可 以使用夾手夾持物料，乂可以使用真空吸盤吸附物料,具有多種用途功能;氣動系 統(tǒng)的電

42、磁換向閥釆用匯流板集裝，減少了占用空間；在PLC的控制下可以實現(xiàn)單 動和連動兩種執(zhí)行方式，完成物料的搬運。英文原文二：Air operated moves the carrier vehicle and the PLC controlThe PLC control system adopts generally easy to understand and to grasptrapezoidal chart language and face industry control simple instruction.
