【摘要】：焊條自動(dòng)包裝生產(chǎn)線是焊條包裝過程中的關(guān)鍵設(shè)備之一。其作用是將焊條生產(chǎn)設(shè)備生產(chǎn)出的焊條經(jīng)過該焊條自動(dòng)包裝生產(chǎn)線后能夠準(zhǔn)確的定位、計(jì)數(shù)、分包、稱量和存儲(chǔ)。通過將生產(chǎn)出的焊條分包和稱重后,以達(dá)到符合企業(yè)和國(guó)家生產(chǎn)要求的目的。 本課題研究的主要內(nèi)容是針對(duì)當(dāng)前我國(guó)焊條包裝機(jī)包裝不準(zhǔn)確和存儲(chǔ)自動(dòng)化水平較低,進(jìn)口焊條包裝生產(chǎn)線價(jià)格昂貴等問題,研究和開發(fā)了一種能夠自動(dòng)分包、計(jì)數(shù)、稱重和存儲(chǔ)的焊條自動(dòng)包裝生產(chǎn)線。提出了一種加速分離法,實(shí)現(xiàn)了焊條的準(zhǔn)確計(jì)數(shù)和定位,同時(shí)還提出了一種中值比較控制方法,來保證焊條的包裝質(zhì)量。該生產(chǎn)線已在天津元達(dá)工貿(mào)有限公司和天津大橋焊材有限公司得到工程應(yīng)用。 本課題的主要研究成果包括： (1)根據(jù)當(dāng)前我國(guó)焊條生產(chǎn)企業(yè)的焊條包裝機(jī)計(jì)數(shù)不準(zhǔn)確,包裝重量不合格的問題,設(shè)計(jì)研發(fā)了一種能夠自動(dòng)計(jì)數(shù)、自動(dòng)分包和稱重的焊條自動(dòng)包裝機(jī)。并深入研究國(guó)內(nèi)外焊條包裝計(jì)數(shù)方法,提出了一種加速分離法,實(shí)現(xiàn)了焊條的準(zhǔn)確計(jì)數(shù)和定位。 (2)結(jié)合焊條包裝機(jī)存在故障的情況下,焊條存儲(chǔ)大都采用人工操作、就地存儲(chǔ)的問題,設(shè)計(jì)研發(fā)了一種能夠自動(dòng)存儲(chǔ)焊條和取焊條的焊條自動(dòng)儲(chǔ)料箱,使得焊條能夠整齊的存放在存料箱中,并能整齊的取出,實(shí)現(xiàn)了自動(dòng)存儲(chǔ)功能。 (3)研究采用PLC作為控制核心的焊條自動(dòng)包裝生產(chǎn)線控制系統(tǒng)。分別利用RS232通訊實(shí)現(xiàn)PLC、稱重模塊和文本屏的實(shí)時(shí)通訊。并提出了一種中值比較控制方法,通過該方法,實(shí)現(xiàn)了焊條自動(dòng)包裝生產(chǎn)線的計(jì)數(shù)、分包、稱重、自動(dòng)存儲(chǔ)的功能。 (4)通過變頻器技術(shù),控制電機(jī)的運(yùn)行速度。根據(jù)焊條生產(chǎn)企業(yè)的不同包裝速度的要求,通過改變變頻器的頻率控制電機(jī)的轉(zhuǎn)速,實(shí)現(xiàn)了焊條自動(dòng)包裝生產(chǎn)線對(duì)速度的控制要求。
[Abstract]:Welding rod automatic packaging line is one of the key equipment in the process of electrode packaging.Its function is that the electrode produced by the electrode production equipment can accurately locate, count, subcontract, weigh and store after the welding rod automatic packaging production line.By subcontracting and weighing the produced electrode to meet the production requirements of the enterprise and the state.The main research content of this subject is to research and develop a kind of automatic subcontracting and counting, aiming at the problems of inaccurate packaging of welding rod packaging machine, low level of storage automation and high price of imported welding rod packaging production line in our country.Weighing and storing welding rod automatic packaging production line.An accelerated separation method is proposed to realize the accurate counting and positioning of the electrode, and a method of median comparison control is also proposed to ensure the packing quality of the electrode.The production line has been applied in Tianjin Yuanda Industry and Trade Co., Ltd and Tianjin Bridge Welding material Co., Ltd.The main research results of this topic include:According to the problems of inaccurate counting and unqualified packing weight of welding rod packing machine in China's welding rod production enterprises, a welding rod automatic packing machine which can count, subcontract and weigh automatically is designed and developed.The method of packing counting of welding rod at home and abroad is studied, and an accelerated separation method is proposed to realize the accurate counting and positioning of electrode.Under the condition of the failure of the welding rod packing machine, the storage of the welding rod is mostly manual operation and local storage. A kind of automatic storage box is designed and developed, which can automatically store the electrode and take the electrode.The welding rod can be neatly stored in the storage box, and can be taken out neatly, realizing the automatic storage function.The control system of welding rod automatic packaging production line with PLC as the control core is studied.The real time communication between RS232, weighing module and text screen is realized by using RS232 communication.A method of median comparison control is proposed, through which the functions of counting, subcontracting, weighing and automatic storage of welding rod automatic packaging line are realized.The speed of motor is controlled by frequency converter technology.According to the requirements of different packing speed of welding rod production enterprises, the speed control requirements of welding rod automatic packaging production line are realized by changing the frequency of frequency converter to control the speed of motor.
