【摘要】：隨著消費(fèi)要求的日漸增高，消費(fèi)者對果蔬產(chǎn)品的安全、保鮮、外形包裝等的要求越來越高，近年來對果蔬的包裝日漸重視起來。本課題對果蔬自動包裝機(jī)進(jìn)行設(shè)計及開發(fā)，不僅符合杭州百鄉(xiāng)緣農(nóng)產(chǎn)品開發(fā)有限公司對農(nóng)產(chǎn)品機(jī)械開發(fā)的要求，同時也是現(xiàn)今農(nóng)產(chǎn)品包裝機(jī)械的重點(diǎn)研究對象。 本課題設(shè)計開發(fā)的果蔬自動包裝機(jī)，機(jī)器完成果蔬送料、包裝薄膜袋狀成型、包裝袋袋口封合及包裝成品輸出整個包裝過程，包裝機(jī)自動化程度高，各類包裝參數(shù)都可通過人機(jī)交互界面進(jìn)行設(shè)定，由總控制系統(tǒng)（PLC）配合伺服系統(tǒng)進(jìn)行控制給予信號反饋使機(jī)構(gòu)自動完成相應(yīng)的包裝動作。 果蔬自動包裝機(jī)的設(shè)計過程是：（1）根據(jù)包裝要求、包裝過程確定技術(shù)參數(shù)和包裝機(jī)構(gòu)，分析確定包裝的工藝流程。根據(jù)對包裝機(jī)外形美觀、機(jī)構(gòu)布局緊湊不松散、操作簡易不復(fù)雜等要求，對機(jī)器整體進(jìn)行合理布局。（2）根據(jù)工序要求以及機(jī)器運(yùn)動與傳遞的關(guān)系設(shè)計機(jī)器的傳動系統(tǒng)，確定傳動比。（3）針對機(jī)構(gòu)的作用，對相應(yīng)執(zhí)行機(jī)構(gòu)進(jìn)行選擇或設(shè)計。其中，重點(diǎn)對果蔬自動包裝機(jī)的制袋成型器和端封機(jī)構(gòu)進(jìn)行創(chuàng)新設(shè)計。（4）根據(jù)果蔬包裝的非規(guī)則性，設(shè)計了果蔬自動包裝機(jī)的控制系統(tǒng)。該系統(tǒng)以可編程邏輯控制器（PLC）為控制核心，通過變頻器控制電機(jī)轉(zhuǎn)速，實現(xiàn)各機(jī)構(gòu)的速度匹配，完成包裝的整個過程。PLC的應(yīng)用，大大減少了包裝機(jī)控制系統(tǒng)設(shè)計、安裝、調(diào)試的工作量，并利用傳感器實時調(diào)節(jié)，使包裝機(jī)達(dá)到高自動化、機(jī)構(gòu)高度同步、包裝定位精準(zhǔn)、包裝效率高、包裝質(zhì)量好等要求。 本課題研發(fā)的果蔬自動包裝機(jī)，自動化程度高，，精度高、效率高、包裝效果好，不僅能適應(yīng)不同尺寸規(guī)格的果蔬包裝，同時也能對其他領(lǐng)域如食品、醫(yī)藥、日用品等的產(chǎn)品進(jìn)行包裝，而且能滿足現(xiàn)今消費(fèi)者對果蔬產(chǎn)品的安全、保鮮、外形包裝等日漸增長的需求。機(jī)器的研發(fā)不僅擁有廣闊的市場、滿足消費(fèi)者的需求，同時對包裝機(jī)械在果蔬領(lǐng)域進(jìn)一步的發(fā)展有積極促進(jìn)作用。
[Abstract]:With the increasing demand of consumption, consumers have higher and higher requirements for the safety, freshness, shape packaging of fruit and vegetable products. In recent years, more and more attention has been paid to the packaging of fruits and vegetables. The design and development of the automatic packaging machine for fruits and vegetables not only meet the requirements of Hangzhou Baixiang Agricultural Product Development Co., Ltd. At the same time, it is also the key research object of agricultural packaging machinery. The design and development of the automatic packaging machine for fruits and vegetables, the machine completed the delivery of fruit and vegetables, packaging film bag forming, packaging bag mouth sealing and packaging finished product output of the whole packaging process, packaging machine automation is high. All kinds of packaging parameters can be set by man-machine interaction interface, and the main control system (PLC) and servo system are used to control and give signal feedback so that the mechanism can automatically complete the packaging action. The design process of the automatic packaging machine for fruits and vegetables is: according to the packaging requirements, the packaging process determines the technical parameters and the packaging mechanism, and analyzes and determines the technological process of the packaging. According to the appearance of the packaging machine, the appearance of the packaging machine is beautiful. The mechanism layout is compact and not loose, the operation is simple and not complicated, the reasonable layout of the whole machine. 2) according to the requirements of the working procedure and the relation between the machine movement and the transmission, the transmission system of the machine is designed. Determine the transmission ratio. 3) according to the role of the mechanism, the corresponding executive mechanism is selected or designed. Emphasis is placed on the innovative design of the bag making and end sealing mechanism of the automatic fruit and vegetable packaging machine) according to the irregularity of fruit and vegetable packaging. The control system of the automatic packaging machine for fruits and vegetables is designed. The PLC controller is used as the control core and the speed of the motor is controlled by frequency converter to realize the speed matching of each mechanism. The application of PLC in the whole process of packaging greatly reduces the workload of the design, installation and debugging of the control system of the packaging machine, and the real-time adjustment of the sensor makes the packaging machine achieve high automation. High synchronization mechanism, accurate packaging positioning, high packaging efficiency, good packaging quality and other requirements. The automatic packaging machine for fruits and vegetables developed in this paper has high degree of automation, high precision, high efficiency and good packaging effect. It can not only adapt to the packaging of fruits and vegetables of different sizes, but also can be used in other fields such as food and medicine. Daily necessities and other products packaging, and can meet today's consumers on the safety of fruit and vegetable products, fresh, packaging and other growing needs. The development of machinery not only has a broad market. To meet the needs of consumers and to promote the further development of packaging machinery in the field of fruits and vegetables.
