摘要：為解決C600原機“煙包異位”故障頻發問題，防止出現原機抓取過程中產生的夾壞缺陷煙引起六角輪卡阻或流入市場等問題，在不改變原機機械傳動的基礎上，采用激光測距技術與伺服控制技術相結合的方法，設計了一套轉煙器蜘蛛手煙包實時同步傳送控制裝置。該裝置主要由激光位移傳感器、伺服驅動器、伺服電機、人機交互界面、報警器等部件組成，可以準確測量煙包與轉煙器蜘蛛手的相對位置，實時調整轉煙器入口皮帶運行速度，確保轉煙器蜘蛛手能夠同步抓取煙包，相關數據信息顯示于人機界面，用于維修、調整。試驗結果表明：改進后實現了轉煙器蜘蛛手準確抓取煙包精度，蜘蛛手與煙包相對位移量的精確控制能力大幅提高了約67%，可以從改進前較難控制的±6mm精準控制到±2mm，相應卡阻次數平均每班減少了98%。

Abstract： In order to solve the frequent problem of "cigarette pack out of place" failures of the original C600 machine， and to prevent causing the hexagonal wheel to block or defect cigarette pack flow into the market， which caused by the defective cigarette caught in the process of grabbing by the original machine， based on the combination of laser ranging technology and servo control technology， a set of real-time synchronous transmission control device for cigarette packet and spider hand of cigarette rotator was designed without changing the mechanical transmission of the original machine. The device is mainly composed of laser displacement sensor， servo driver， servomotor， human-computer interaction interface， alarm and other components. It can accurately measure the relative position of the cigarette pack and the spider hand of the cigarette rotator， and adjust the running speed of the belt at the entrance of the cigarette rotator in real time， to ensure that spider hand of the cigarette rotator can grab the cigarette pack synchronously， the relevant data information is displayed on the man-machine interface for maintenance and adjustment. The test results show that the accuracy of the spider's hand grasping the cigarette packet is achieved after the improvement. The precision control ability of the relative displacement between the spider's hand and the cigarette packet is greatly improved by about 67%， which can be controlled from ±6mm which is difficult to control before the improvement to ±2mm and the number of jamming is reduced by 98% on average per shift.

C600包裝機是卷煙廠硬包高速生產線的重要設備。該機大多采用蜘蛛手機構實現煙包90°平移轉向，但受輔料變換、設備配合精度降低等因素的影響，在長期的生產過程中，“煙包異位”故障頻繁發生，夾壞煙包，引起機器卡阻，引發質量隱患。為此在不改變原機機械傳動的基礎上，采用激光測距技術和伺服控制方法，設計一套轉煙器蜘蛛手煙包實時同步傳送控制裝置，以期降低故障率，增加生產效率。……
