【摘要】：隨著我國科技社會的不斷發(fā)展，，人力成本的不斷提高，企業(yè)越來越重視生產(chǎn)的效率和成本。在我國包裝行業(yè)中，許多設(shè)備還非常落后，自動化水平也非常低下，有的甚至還是手工生產(chǎn)，這種狀況極大的限制了行業(yè)和企業(yè)的發(fā)展。特別是復(fù)合包裝袋的生產(chǎn)，絕大多數(shù)企業(yè)還是采用人工的生產(chǎn)方式，人工的方式不僅勞動強度大，而且效率低下。 針對這種情況，在經(jīng)過大量的實驗和分析的基礎(chǔ)上，結(jié)合合作公司的具體要求，提出了雙工位自動塞袋的工作方式，采用歐姆龍可編程控制器作為主要的控單元，采用歐姆龍觸摸屏作為人機界面，根據(jù)工藝要求確定機械總體方案及各個功能模塊，并選用PLC的型號及其擴展模塊，編制系統(tǒng)控制軟件。雙工位自動控制的設(shè)計方案，不僅可以提高系統(tǒng)的穩(wěn)定性和可靠性，還能大幅降低設(shè)計難度和設(shè)計成本。該方案可使復(fù)合包裝袋的生產(chǎn)效率達到25個/分鐘，大大提高了工作效率，不僅達到預(yù)期的目的，還具有一定的提升空間。本文主要內(nèi)容如下： 1.根據(jù)復(fù)合袋包裝袋的生產(chǎn)工藝及合作廠商的要求，確定了雙工位自動塞袋機的總體設(shè)計方案和整體機械機構(gòu)的設(shè)計。 2.根據(jù)具體機械結(jié)構(gòu)提出了PLC與觸摸屏結(jié)合的控制方式，通過PLC控制整個復(fù)合袋生產(chǎn)過程，通過觸摸屏進行復(fù)合袋生產(chǎn)過程進行監(jiān)控。 3.根據(jù)功能需要設(shè)計了雙工位塞袋機的氣動系統(tǒng)，通過詳細的計算確定了重要氣動元件的類型。 4.設(shè)計了控制系統(tǒng)的硬件結(jié)構(gòu)，包括PLC及其擴展、伺服電機和步進電機、傳感器、控制箱等部件；詳細敘述了伺服系統(tǒng)的設(shè)計。 5.根據(jù)要求設(shè)計PLC系統(tǒng)控制程序及觸摸屏監(jiān)控程序，介紹了歐姆龍觸摸屏編程軟件NB—Designer的特點，介紹了觸摸屏監(jiān)控界面的登陸界面、主界面、系統(tǒng)參數(shù)界面、單步控制界面、報警界面；介紹了歐姆龍PLC編程軟件CX—Programmer的特點，介紹了控制系統(tǒng)的總流程、及各個子程序流程。 6.研究了雙工位自動塞袋機的調(diào)試方式，并對設(shè)計的結(jié)構(gòu)和設(shè)計的創(chuàng)新性進行總結(jié)。
[Abstract]:With the development of science and technology society and the improvement of manpower cost, enterprises pay more and more attention to the efficiency and cost of production. In the packaging industry of our country, many equipments are still very backward, automation level is also very low, some even manual production, this kind of situation greatly limits the development of the industry and the enterprise. In particular, the production of composite packaging bags, the vast majority of enterprises still adopt artificial mode of production, manual method is not only labor intensity, but also low efficiency. In view of this situation, on the basis of a large number of experiments and analyses, combined with the specific requirements of the cooperation company, this paper puts forward the working mode of the double station automatic plug bag, which adopts the OMRON programmable controller as the main control unit, and makes use of the OMRON programmable controller as the main control unit. The OMRON touch screen is used as the man-machine interface, the overall mechanical scheme and each functional module are determined according to the technological requirements, and the model of PLC and its extension module are selected to compile the system control software. The design scheme of duplex automatic control can not only improve the stability and reliability of the system, but also greatly reduce the design difficulty and design cost. This scheme can make the production efficiency of the composite packing bag up to 25 / min, greatly improve the work efficiency, not only achieve the desired purpose, but also have some room for improvement. The main contents of this paper are as follows: 1. According to the production technology of the compound bag packing bag and the requirements of the cooperative manufacturers, the overall design scheme and the design of the whole mechanical mechanism of the double station automatic bag stopper are determined. 2. According to the specific mechanical structure, the control mode of the combination of PLC and touch screen is put forward. The whole production process of the composite bag is controlled by PLC, and the production process of the compound bag is monitored by the touch screen. 3. According to the need of function, the pneumatic system of double-station plug bag machine is designed, and the types of important pneumatic components are determined by detailed calculation. 4. The hardware structure of the control system is designed, including PLC and its extension, servo motor and stepping motor, sensor, control box and so on, and the design of servo system is described in detail. 5. The PLC system control program and touch screen monitoring program are designed according to the requirements. The characteristics of OMRON touch screen programming software NB-Designer are introduced. The landing interface, main interface, system parameter interface and single step control interface of touch screen monitoring interface are introduced. Alarm interface; This paper introduces the characteristics of OMRON PLC programming software CX-Programmer, introduces the general flow chart of the control system, and the sub-program flow chart. 6. The debugging mode of double station automatic bag stopper is studied, and the structure and innovation of design are summarized.
