不干膠自動(dòng)貼標(biāo)機(jī)說(shuō)明書畢業(yè)論文(存儲(chǔ)版)

  

【正文】 牽引輪、標(biāo)簽輸送的定位機(jī)構(gòu)、標(biāo)簽的自動(dòng)剝離桿以及標(biāo)簽紙帶的回收輪來(lái)完成整個(gè)送標(biāo)動(dòng)作,必要時(shí)添加導(dǎo)向輥。具體研究?jī)?nèi)容如下: 根據(jù)貼標(biāo)機(jī)功能,應(yīng)用的范圍和工藝方法,確定貼標(biāo)機(jī)的類型,合理安排貼標(biāo)機(jī)的加工工序、工藝路線和工位數(shù)。當(dāng)這個(gè)機(jī)械裝置伸展到標(biāo)簽與包裝件相接觸后,就收縮回去,此時(shí)就將標(biāo)簽貼附到包裝件上。(4)特殊類型的專業(yè)機(jī)械,種類多,生產(chǎn)數(shù)量有限。標(biāo)簽上的商標(biāo)、主要參數(shù)、使用說(shuō)明和產(chǎn)品介紹,是現(xiàn)代包裝不可缺少的,而且設(shè)計(jì)精美的標(biāo)簽還有助于提升公司形象,促進(jìn)產(chǎn)品的銷售。在醫(yī)藥,啤酒瓶裝裝設(shè)備中,高速回轉(zhuǎn)式貼標(biāo)機(jī)是醫(yī)藥,啤酒瓶裝生產(chǎn)線上重要設(shè)備之一。本文對(duì)自動(dòng)貼標(biāo)機(jī)的貼標(biāo)過(guò)程作出設(shè)計(jì)理論,解決國(guó)內(nèi)醫(yī)藥行業(yè)瓶裝生產(chǎn)線(中的重要部分)貼標(biāo)機(jī)的設(shè)計(jì)開(kāi)發(fā),對(duì)外形和功能進(jìn)行設(shè)計(jì),對(duì)相關(guān)參數(shù)進(jìn)行計(jì)算,繪制出自動(dòng)貼標(biāo)機(jī)的裝配圖和各部件的部件圖和零件的零件圖。其次,針對(duì)現(xiàn)在醫(yī)藥瓶裝生產(chǎn)線的生產(chǎn)率進(jìn)行設(shè)計(jì)計(jì)算,作為以后自動(dòng)貼標(biāo)機(jī)設(shè)計(jì)的理論基礎(chǔ)。在國(guó)內(nèi),一些醫(yī)藥和啤酒設(shè)備生產(chǎn)廠家開(kāi)始引進(jìn)吸收克朗斯公司的技術(shù)進(jìn)行設(shè)計(jì)生產(chǎn)國(guó)產(chǎn)系列的高速回轉(zhuǎn)式貼標(biāo)機(jī)并取得了成效,其中以廣東輕工業(yè)機(jī)械集團(tuán)有限公司,青島機(jī)床啤酒設(shè)備有限公司等為代表。從早期的貼單一標(biāo)發(fā)展到貼雙標(biāo)、環(huán)身標(biāo)、肩標(biāo)、頸標(biāo),掛標(biāo),以祭器它能夠增加商品美感的裝演形式,原來(lái)簡(jiǎn)單手動(dòng)貼標(biāo)形式已遠(yuǎn)不能滿足生產(chǎn)的需要,一些功能齊全、產(chǎn)量高、自動(dòng)化程度高的貼標(biāo)機(jī)便問(wèn)世了,并且飛速發(fā)展。目前,主要的自動(dòng)貼標(biāo)技術(shù)有三種:(1)“吹貼法”(或“射流法”) 這種技術(shù)的某些運(yùn)作方式是與上述吸貼法相似的,就是將標(biāo)簽放置到真空表面墊上固定,直到貼附動(dòng)作開(kāi)始為止。在貼標(biāo)時(shí),當(dāng)標(biāo)簽的前緣部分粘附到包裝上后,產(chǎn)品就馬上帶走標(biāo)簽。(2)確定自動(dòng)貼標(biāo)機(jī)結(jié)構(gòu)繪制出裝配圖,部件圖和零件圖,寫出設(shè)計(jì)說(shuō)明書。(4) 撫壓機(jī)構(gòu)撫壓機(jī)構(gòu)也是貼標(biāo)機(jī)的工藝操作機(jī)構(gòu), 因而標(biāo)簽剝離出的前緣被粘在瓶子上后,還需使用滾筒或是刷子,在標(biāo)簽和瓶子同時(shí)從工位2運(yùn)動(dòng)到工位3的過(guò)程中,將標(biāo)簽的剩余部分在瓶子上撫平壓實(shí)。下面對(duì)所研制的貼標(biāo)機(jī)的具體工藝進(jìn)行分析。同時(shí)貼標(biāo)機(jī)也具有其自身的一些特點(diǎn),根據(jù)本貼標(biāo)機(jī)的工藝,可將貼標(biāo)機(jī)的結(jié)構(gòu)劃分為以下幾個(gè)部分,如圖24所示:瓶子輸送機(jī)構(gòu)圖24貼標(biāo)機(jī)的結(jié)構(gòu)組成方塊圖瓶子輸送機(jī)構(gòu)瓶子輸送機(jī)構(gòu)本論文主要是設(shè)計(jì)自動(dòng)貼標(biāo)機(jī)實(shí)現(xiàn)功能的機(jī)械部分。由于本貼標(biāo)機(jī)使用的是伺服電機(jī),本級(jí)的主要載荷均為輕載,主要為直線運(yùn)動(dòng)特性使得在貼標(biāo)機(jī)的機(jī)械結(jié)構(gòu)中省去了許多傳動(dòng)機(jī)構(gòu),因而把傳動(dòng)裝置歸入到各工作機(jī)構(gòu)中。這種方式在本系統(tǒng)中應(yīng)用時(shí),一般都要使用步進(jìn)電機(jī)進(jìn)行驅(qū)動(dòng),配以專門的托盤。型號(hào)為70SL5C2,額定輸出功率為160W,f=50HZ 勵(lì)磁電壓為110V,堵轉(zhuǎn)轉(zhuǎn)矩為104 ,空轉(zhuǎn)轉(zhuǎn)速最大為1000r/min,重量為1600g。送標(biāo)動(dòng)作是通過(guò)標(biāo)簽輸送裝置的工作實(shí)現(xiàn)的,因此標(biāo)簽輸送裝置要滿足以下的基本功能和運(yùn)動(dòng)要求: ,使得標(biāo)簽卷在送標(biāo)過(guò)程中可退卷 ,使標(biāo)簽移動(dòng)指定距離 ,以確保貼標(biāo)精度 ,自動(dòng)剝離,這是實(shí)現(xiàn)自動(dòng)貼標(biāo)的關(guān)鍵之一54321由此可確定標(biāo)簽輸送裝置是由以下5個(gè)裝置組成的,如圖31所示:圖31標(biāo)簽輸送裝置的組成1,標(biāo)簽卷支撐盤 2,導(dǎo)向柱裝置 3,標(biāo)簽紙回收輪 4,導(dǎo)輥組 5,標(biāo)簽剝離桿圖31中的所示的標(biāo)簽卷支撐盤1用于支撐標(biāo)簽卷,使標(biāo)簽卷保持在一定的牽引力的作用范圍內(nèi)可以松展成帶(又稱退卷)。若與導(dǎo)向柱裝置保持相同的角速度,其紙帶的線速度則越來(lái)越大,造成標(biāo)簽紙帶的張力越來(lái)越大,可能會(huì)導(dǎo)致紙帶被拉斷,因此導(dǎo)向柱裝置5的角速度必須小于標(biāo)簽卷的角速度?,F(xiàn)代自動(dòng)包裝機(jī)中常用的驅(qū)動(dòng)元件是步進(jìn)電機(jī),它們具有響應(yīng)快,信號(hào)檢測(cè)、傳遞、處理方便的特點(diǎn)。在此貼標(biāo)機(jī)中,設(shè)計(jì)了一塊升降板使標(biāo)簽輸送和回收裝置的所有部件都安裝在此升降板上,升降板的形狀和外形尺寸如下圖32,升降板用螺紋桿安裝在工作臺(tái)上,為了受力均勻需要對(duì)升降板的形心進(jìn)行計(jì)算,計(jì)算如下:貼標(biāo)機(jī)構(gòu)所在升降板的形狀如下所示,這是一塊密度均勻的板,其形心和重心是重合的,所以可以計(jì)算其重心代替形心。 剝離機(jī)構(gòu)的設(shè)計(jì)在送標(biāo)過(guò)程中,標(biāo)簽可靠地自動(dòng)剝離,是順利貼標(biāo)的前提,如果標(biāo)簽不能剝離,或是剝離出的部分的位置和姿態(tài)不適當(dāng),都會(huì)致使無(wú)法完成貼標(biāo)。本例為標(biāo)簽紙帶薄而柔的情況。因此加設(shè)了導(dǎo)向輥,使得在標(biāo)簽卷和剝離桿之間的豎直距離h不變的情況下。以上三點(diǎn)方案設(shè)計(jì)和實(shí)施后,提高了送標(biāo)過(guò)程中標(biāo)簽的剝離可靠性,且剝離裝置的結(jié)構(gòu)簡(jiǎn)單,容易調(diào)節(jié)。 為使貼標(biāo)機(jī)的結(jié)構(gòu)簡(jiǎn)單,貼標(biāo)機(jī)構(gòu)完成貼標(biāo)后,在瓶子、標(biāo)簽沿水平方向同時(shí)進(jìn)給時(shí),回轉(zhuǎn)的標(biāo)簽壓緊機(jī)構(gòu)(垂直放置的同步帶)在標(biāo)簽上撫過(guò),使標(biāo)簽完全粘附在瓶子上。人們?yōu)榱藦耐饨绔@取信息,必須借助于感覺(jué)器官。  在基礎(chǔ)學(xué)科研究中,傳感器更具有突出的地位。 在本設(shè)計(jì)中分瓶輪采用與牽引輪有相同的步距角的伺服電機(jī),但從分瓶裝置完成,送標(biāo)裝置同步動(dòng)作,如果采用人工控制,難以達(dá)到同步運(yùn)行,且操作復(fù)雜,這時(shí)可以采用安裝傳感器實(shí)現(xiàn)這一動(dòng)作。不斷的根據(jù)市場(chǎng)需求變化,改變企業(yè)的發(fā)展步伐,開(kāi)發(fā)低耗能、高效率、低成本的全自動(dòng)貼標(biāo)機(jī)來(lái)迎合市場(chǎng)需求,促進(jìn)國(guó)內(nèi)貼標(biāo)機(jī)行業(yè)發(fā)展。而提高包裝質(zhì)量和外觀檔次,關(guān)鍵的設(shè)備當(dāng)屬貼標(biāo)機(jī)。在送標(biāo)裝置中,根據(jù)送標(biāo)的動(dòng)作要求,設(shè)計(jì)了成本低,結(jié)構(gòu)簡(jiǎn)單,傳動(dòng)可靠,速度調(diào)節(jié)容易的轉(zhuǎn)位機(jī)構(gòu),實(shí)現(xiàn)了標(biāo)簽的單向間歇性的進(jìn)給運(yùn)動(dòng);通過(guò)標(biāo)簽剝離試驗(yàn)和對(duì)剝離力的理論分析,確定了剝離裝置的較優(yōu)設(shè)計(jì)參數(shù)。s Packing Industry [R].GuangZhou: INDUSTRY SECTOR ANALYSIS, 1998 附錄一? Labeling machine Labeling machines is to glue paper or foil labels on the containers provided by the device. In the 18th century there was a simple manual labeling tool, now has more than 200 years, the industrial revolution promoted the advancement of industrial technology from early single object labeling tool development to pastes standard twin, ring, shoulder, neck, plete functions, high yield, high degree of automation of the labeling machine.(1) some knowledge about labeling machines are described below:First,The classification, labeling machine.In accordance with different adhesive coating, labeling machines can be divided into selfadhesive labeling machine, cold glue labeling machine (cold glue labeling machine, glue labeling machine) and hot melt Adhesive labeling machine categories. In accordance with the degree of automation, can be divided into fully automated, automatic, semiautomatic and manual labeling machine categories. By the realization of different labeling function, can be divided into plane Labeler, labeler and labeler class in a circle in the side. Labeling machines are: adhesive labeling machine, labeling machine, round bottle labeling machine, beer labeling machine, semiautomatic labeling machine, labeling machine, automatic labeling machine, automatic Labeler, label machine, automatic paste labeling machine, hot melt labeling machine. These products plete the paste plane, on one or more surfaces of the package paste, cylindrical paste, paste partial coverage or full coverage cylinder, SAG and corner parts of paste and so on.Second, labeling machines used to define.Subject: on the label attached to the packaging, center line and its theoretical deviation of the position of the label within the specified range, known as being marked. Have more than one label on the same container, should seek out their definition and theoretical deviation of the position mentioned above, should be within the specified range.Labeling rate: in accordance with the labelling requirements (Dan Biao or standard) labelled packaging container and check the number of percentage of the total number of containers.Loss rate: in the process of labeling, were damaged by labeling machine tag number and check the packaging container labeling the amount of percentage of the total number of tags.Standard rate: check the packaging of containers, packaging container and check the number of percentage of the total number of containers.Labeling machine type: plane class labeling machine implemented in artifacts on the label of the arc on the plane, and foil, such as boxes, books, plastic shell, roll up and stick two ways, based primarily on efficiency, precision, and bubble requires a selection.Round bottle labeling machine to achieve the circle of cylindrical, conical product label or foil on the surface, such as glass bottles, plastic bottles, and so on, can achieve circle, halfcircle, circle, circle position on both sides features such as labeling, there are horizontal and vertical labeling labeling in two ways. Side labeling machine to achieve lateral plane, side of the workpiece Globoidal label or foil, flat bottle, cosmetics box, matching wrapcovering standard equipment, while round bottle labeling.Third, how it works.Regardless of which kind of labeling machines, labeling process is broadly similar, the difference is: labeling equipment to install in different locations, go through the send method, position of label objects in different ways, an
