(c) screen s assembly line signal, some for input signals, such as request print signal。 The initialization of barcode printers of setting the necessary serial munication, 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)。 E) rotating cylinder toward glass screen direction。 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(shù)師范大學(xué) 2020屆本科生畢業(yè)設(shè)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。通過對貼標機的工作要求分析 ， 確定了系統(tǒng)的總體設(shè)計方案 ， 研究并解決了貼標機設(shè)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(guān)鍵技術(shù)問題 ， 該標簽粘貼機已實際應(yīng)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(chǎn)線的屏網(wǎng)組裝工序 ， 取得了良好的效果。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.
