​印務公司印刷機側規誤發信號,造成機器開不動。其原因有以下兩點(1)紙到位發信號。在印刷中,有時側規拉紙到位後,檢測裝置發信號造成輸紙機停止工作,經檢測發現,側規拉紙到位的檢測位置靠外,雖然紙張已經到位,但檢測器還未掃描到紙張,因而發出了紙張不到位的信號。
印務公司印刷機側規誤發信號造成機器開不動

印務公司印刷機側規誤發信號,造成機器開不動。其原因有以下兩點(1)紙到位發信號。在印刷中,有時側規拉紙到位後,檢測裝置發信號造成輸紙機停止工作,經檢測發現,側規拉紙到位的檢測位置靠外,雖然紙張已經到位,但檢測器還未掃描到紙張,因而發出了紙張不到位的信號。

印務公司排除的方法:調整側規檢測器的電眼,使其與到位紙張對齊即可。

紙張已經過位,但不發信號。在機器操作中,有時紙張已經超過了側規定位位置,但檢測器卻不發信號,使得超過定位線的紙張進入印刷,造成橫向套印不準。

此時檢測側規本身沒有問題,只是不給檢測信號。經檢查分析發現檢測器的光線被紙粉和灰塵遮擋,接收不到信號。

海德堡機器側規檢測裝置中用了砷化鎵二極管作為發射器,而長時間印刷紙質低劣的印刷品時,由於紙毛和紙粉塵太多,把電眼遮蓋後,使檢測器失靈,造成不發信號

排除的方法:停機清洗檢測器的臟物,恢復電眼的檢測功能,同時平時在機器的維修保養中,也要註意經常清潔。
