【導讀】自動貼標機的效率高，所以有一定的制造和使用價值。本貼標機的主要工作部件有輸送機構、放紙機構、壓標機構等。提供動力，并且對工作機分別進行了輸送機構、貼標機構的動力設計。其次設計各個結構，計算各個尺寸，繪制出貼標機的裝配圖和零件圖。本論文校核了放紙軸和螺栓的強度和剛度，并計算了滾動軸承的壽命。

　　

【正文】 ion, to set up the parameters and the printer paper to go way for state examination printer, whether it has plus electric or in a lack of paper, lack of ribbon etc state. In order to make a printed each bar code label to move out of the print head step to a specific location is sucked head to get but again not wasted tag, we have set up a special printer walked way, namely each paper to print label more after sending a tag (fo－ feed), the next time a fo print label back a certain distance before (back feed), this distance by a text file, according to actual situation provide necessary adjustments. system in place Labeling machines in formal run before to perform in situ operation, to indicate mechanical and electrical condition normal. In this process, labeling machines main check whether the following conditions satisfy: A) pressed air open (pressure gauge reading instruction 4 Pa ~ 6 Pa)。 B) vacuum open。 C) power open。 D) linear cylinder in contracted position。 E) rotating cylinder toward glass screen direction。 F) tag stripping intake pipe closed。 G) silica gel suction head neither pressed air role, and no vacuum action。 H) bar code printer initialization, a blank normal ceramic tags in stripping state and is located in the location specified。 I) puter display information waiting for shadow mask. label position adjustment Marking machine is to stick to print out ceramic tags and its automatic paste into the glass screen tube 29 inches long edge center position. Specific requirement is: the label with the horizontal center position of display horizontal center should coincide label from the screen writes adhesive position for 27 mm, edge position of horizontal and vertical direction errors are for l mm. In addition, tag and the screen glass can leave between any air or bubble. In order to acplish this purpose, need to undertake necessary adjustments. In order to make the label every time after printing are located in proper position for suction head drain, need to make sure that the labels about 0. 3 mm still stuck in the 天津職業(yè)技術師范大學 2020屆本科生畢業(yè)設計 19 remainder on mounts, be stripped. In practical terms, should meet the following conditions: A) tags hanging in almost perpendicular corner form securing plate, label above level. B) tag is located in the high position, embodied when making when it is drain and paste to screen, tag after writes adhesive edge with screen the distance to 27 mm. C) tags in appropriate levels (or so) position, make when it is drain rotation and paste to screen the horizontal center, tag after the position and screen level center position almost superposition. D) tags in a certain level to maintain mounts range. The above conditions by limiting label is travel and adjust Angle, the height and Angle of fixed board to meet, including the trip is in a printer label when initialized by software control. Label the horizontal position on post screen mainly by two factors: one for cable is printer internal rolls label position, the position on the support by roller adjusted fixed block。 Another factor is the printer level position, because the printer is through its bottom four unscrew the label catwalk fixed, including unscrew hole, and waist form is horizontal position can adjust. Note that the label is due by 180. Rotating device was paste to the screen, and the direction of movement and the printer or so of final in screen label horizontal direction opposite. bar code printing steel mand equipped Different barcode printers, and its control and programming mands are different. This system USES American DAlrAMAx pany39。s PRODIGY PLus heat transfer type barcode printers, its detailed control mand can refer to random manuals. The following list associated with this system control mand several monly, these orders through the form of string by controlling puter through the aRs 232 interface to the printer. A) L: enter label format control mode. B) Hnn: heating temperature control mand, which can be scope for nn by 01 ~ 20. C) Pa: the printing speed control mand, including a scope for a ~ o, represent different printing speed. D) sa: rotary speed control mands, including a scope for a ~ o, represent different rotary speed. E) P: rotary speed control mands, including a scope for a ~ o, represent different rotary speed. F) visible characters printed control format, the string is used to control the people print with visible characters specifications. 天津職業(yè)技術師范大學 2020屆本科生畢業(yè)設計 20 G) bar code printing control format, the string is used to control the bar code print specification. labeling machine control technology Because labeling machine system contains multiple actuators, and action, if the monomer plex electromagic valve control system, certainly will makes system of wiring plex, and high failure rate. For simplified pneumatic control system design, improve the reliability of system operation, choose the two with much of the needle plug valve terminals for centralized control pneumatic system. Control means USES electricity air program control, use PLC to pneumatic sequential control, make the vast and plex system control bee simple and clear. The use of PLC, cylinder magic switch and some sensors can be directly connected with PLC and tell the many intermediate link, simplify control system. Meanwhile, PLC programming simple, modification easy, makes the system action sequence adjustment is very convenient. 天津職業(yè)技術師范大學 2020屆本科生畢業(yè)設計 21 附錄 2： 中文翻譯 一種采用單臺微機控制的標簽粘貼機 摘要 :標簽 粘貼機是一種可自動進行標簽打印和粘貼的設備裝置 ， 在工業(yè)自動化生產中有著廣泛的應用。文中介紹了一種采用單臺微機進行控制的全自動標簽粘貼機的工作原理及各部分組成 ， 以及使用過程中對其進行設置和調整的方法。通過對貼標機的工作要求分析 ， 確定了系統(tǒng)的總體設計方案 ， 研究并解決了貼標機設計過程中包括標簽輸送、標簽剝離、撫壓標簽以及貼標機的 PLC 控制等關鍵技術問題 ， 該標簽粘貼機已實際應用于華飛彩色顯示系統(tǒng)有限套司 29 英寸彩色顯像管生產線的屏網組裝工序 ， 取得了良好的效果。 關鍵詞：條形碼；標簽；條形碼打印機；貼標機
