HONEYWELL 51306733-175使用方法教程,CC-TAID01底板由于印刷機(jī)是一個(gè)精度較高的機(jī)械,印刷品的好壞一方面在于機(jī)械加工以及安裝的精度,另一方面,也取決于水路,墨路的平衡以及合壓的準(zhǔn)確性。雙色機(jī)的每一色組,都有水路和墨路裝置。為了便于水輥速度的調(diào)節(jié),每根水輥都用一個(gè)變頻器控制,同時(shí),主電機(jī)速度也需要變頻器調(diào)節(jié)。因此,為了實(shí)現(xiàn)多路速度調(diào)節(jié),我們采用了三菱4D/A數(shù)模轉(zhuǎn)換器,它將PLC方給出的數(shù)字量,根據(jù)相應(yīng)的算法,轉(zhuǎn)換成0~10V直流電壓輸出,很好地實(shí)現(xiàn)了多路速度調(diào)節(jié)要求。
HONEYWELL 51306733-175使用方法教程 在印刷過(guò)程中,調(diào)版是一個(gè)比較繁瑣的過(guò)程。尤其對(duì)多色機(jī)來(lái)說(shuō),各組版對(duì)正的精度會(huì)對(duì)印品產(chǎn)生很大的影響。如果套印不準(zhǔn),印刷品就會(huì)出現(xiàn)字面重疊或影像不清。一般來(lái)說(shuō),印版軸向調(diào)節(jié)范圍為-2mm~ 2mm ,周向調(diào)節(jié)范圍為-1mm~ 1mm。如果使用手動(dòng)調(diào)版,會(huì)浪費(fèi)很多時(shí)間,而且精度不高。為了實(shí)現(xiàn)自動(dòng)打版,我們?cè)诎孑伾习惭b了電位器,通過(guò)電位器將模擬量傳送給4A/D,經(jīng)過(guò)PLC處理,可將版輥的轉(zhuǎn)動(dòng)精度很好地控制在打版范圍內(nèi)。 觸摸屏作為一種新型的人機(jī)界面,從一出現(xiàn)就受到關(guān)注,它的簡(jiǎn)單易用,強(qiáng)大的功能及優(yōu)異的穩(wěn)定性使它非常適合用于工業(yè)環(huán)境。用戶可以自由地組合文字,按鈕,圖形,數(shù)字等來(lái)處理或監(jiān)控管理隨時(shí)可能變化的信息。隨著機(jī)械設(shè)備的飛速發(fā)展,以往的操作界面需由熟練的操作員才能操作,無(wú)法提高效率。但使用人機(jī)界面,能明確指示并告知操作員機(jī)器設(shè)備目前的狀況,使操作變得簡(jiǎn)單生動(dòng)。使用觸摸屏,還可以使機(jī)器配線標(biāo)準(zhǔn)化,簡(jiǎn)單化,同時(shí)也能減少PLC控制所需的I/O點(diǎn)數(shù),降低生產(chǎn)成本,也相對(duì)提高整套設(shè)備的附加價(jià)值。三菱觸摸屏和三菱PLC有很好的通用性,能在線監(jiān)視并修改程序,不必很麻煩的重復(fù)插拔接口。 3 軟件設(shè)計(jì) 3.1 給紙?jiān)O(shè)計(jì) 印刷機(jī)整體的電氣設(shè)計(jì)還是比較復(fù)雜的,對(duì)時(shí)間的要求也很嚴(yán)格。在機(jī)器的很多地方裝有接近開關(guān),用來(lái)檢測(cè)不同的時(shí)間點(diǎn)。在印刷過(guò)程中,走紙的好壞是影響機(jī)器質(zhì)量的一個(gè)重要環(huán)節(jié)。所謂紙走的好壞,指的是無(wú)歪張,雙張等現(xiàn)象,如果有歪張,雙張現(xiàn)象,在高速情況下,就會(huì)將走壞的紙,卷入機(jī)器內(nèi),從而破壞膠皮,給用戶帶來(lái)很大損失。按照上述流程編制的程序,在低速?zèng)]有問(wèn)題,但速度增高至7000r/h后,就會(huì)出現(xiàn)歪張鎖不住現(xiàn)象。
For some modules with exactly the same or similar size, there is compatibility in hardware, and the connection mode with the motherboard can also be flexibly selected on dip and SMD; The South extension of Xintai expressway was officially opened to traffic on December 31, 2015. It realizes the connection between Xintai Expressway and Western Coastal Expressway, and ends the history of "dead end road" of Xintai expressway. It is an important traffic project connecting Guangfo, Zhuhai, Yangjiang and other areas in Xinhui and Taishan areas. The South extension line of Xintai Expressway starts from Doushan pumice (connecting Xintai Expressway) at the end of Xintai Expressway and connects with the Western Coastal Expressway. The project has a total length of 5.717 km, a design speed of 100 km / h and two-way four lanes. The South extension line of Xintai expressway is one of the most important traffic construction projects in Taishan in recent years. As one of the expressway construction projects in Guangdong Province from 2013 to 2017, it is also the traffic construction project with the largest investment in Taishan in 2015.industrial switch
