震立牌同速自动接纸机，是轮转印刷机的主要配套设备之一，目前广泛应用于报刊，书刊，凹版，柔版印刷机中。本接纸机的最大特点是当印刷机连续印刷时，在不停机的情况下，实现卷筒纸自动交换，达到向印刷主机连续不断地输送纸张，薄膜，铝泊等印刷材料。从而提高了印刷主机的印刷效率，减轻操作工人的劳动强度，并且大大节省印刷材料。Zhenli brand same-speed automatic splicer is one of main incorporated equipment of rotary printing machine, it is extensively applied to newspaper, book and periodicals printing by gravure and flexographic press. This splicer provides prominent feature that web automatic exchange is realized during continuous operation of printing machine without closing down, thus the printed material such as paper, film and aluminum foil is continuously fed. The production efficiency of principal printing machine is improved, labor intensity of operators is decreased, and printed material is substantially saved.

 

一. 机器工作原理  I Operational principle

1．接纸机的主要作用：Main function of splicer

接纸机的主要作用是当印刷主机在印刷过程中，随着一个卷筒纸即将用完，需要更换另一个卷筒纸，在印刷主机不停机的情况下实现从一个卷筒纸到另一个卷筒纸的交换，即自动接纸。并且在这交换过程中保证供给张力的恒定。During printing course, when one web is used up to be replaced by a new one, the splicer functions to realize exchange from one web to another without machine closing down, i.e. automatic splicing. The variableness of feeding tension is also ensured during exchange.

2．同速接纸机的主要工作原理：Operational principle of same-speed splicer

将新装载的纸卷加速，使新纸卷最外表的线速度与正在印刷工作的运行纸卷的线速度相等，即新纸卷与运行纸卷的线速度相对速差为“零”。通过一系列的机械动作及控制系统的控制，使新纸卷的纸在运动过程中成功的接到正在印刷的运行纸卷的纸带上。Accelerate  newly loaded web to make its outmost linear speed equal to that of operating web, i.e. the relative speed difference between linear speed of new web and that of operating web is zero. During operation, through a series of mechanical action and control provided by control system, the new web paper is successfully spliced to paper tape of operating web.

3．同速接纸机的接纸过程Splicing process of same-speed splicer：当接纸机的运行工位上正在使用一个卷筒纸时，将另一个新纸卷装载在接纸机的上纸工位上，并对新卷筒纸完成一切必要的接纸准备工作。As one web is being employed in operating station of splicer, a new web is loaded in its feeding station, all necessary preparatory work  of paper splicing will be completed for new web. 随着运行工位上的卷筒纸直径逐渐减小，当接纸机检测并计算出卷筒纸达到一定的直径时，接纸机自动发出接纸信号，同时接纸铃鸣响，接纸机的主轴和转臂开始旋转，当新纸卷最外表挡住旋转限位接近开关的红外光时，接纸机的主轴和转臂停止旋转，这时接纸臂部件开始旋转下降，直到气缸行程走完而停止。As web diameter of operating station is decreased gradually to certain value, it is detected and calculated by splicer, the splicing signal is given automatically and splicing bell rings, the spindle and tumbler of splicer start to revolve. When the infrared light of rotary limit proximity switch is blocked by outmost surface of new web, revolution of spindle and tumbler stops, the splicing arm part start to spin down until cylinder stroke is finished.      当接纸臂停下后，在一固定的时间内将新纸卷纸边通过电动横向移动来对准运行纸卷的纸边。When splicing arm is stopped, paper edge of new web is aligned to that of operating web through electric transverse movement within a fixed time.随后加速臂部件开始旋转下降，直到加速臂上的加速皮带完全压紧新纸卷而停止，加速电机开始运转（此时通过电器控制，使印刷主机已不能进行升速的操作），通过加速皮带来带动新纸卷运转，直到新纸卷最外表的线速度与正在印刷工作的运行纸卷的线速度相等，并将稳定的运行一段时间。Afterwards, accelerating arm part start to spin down until new web is entirely compressed tightly by accelerating belt. Accelerating motor starts to run(under electric device control, speed rising of principal printing machine is disabled), new web is dragged into operation by accelerating belt till the outmost linear speed of new web equal to that of operating web, a period of stable operation will be kept.  当运行纸卷的直径达到人工预设的残卷直径时，接纸臂部件上的泡沫辊压下，使运行纸卷的纸带紧贴新纸卷的表面，当新纸卷上的双面胶带纸运行到泡沫辊下时，就会将新旧纸卷的纸带进行粘接，接纸机的裁刀此时将用完的卷筒纸切断。 As the operating web diameter reaches preset value of residual web, the foam roll of splicing arm is pressed down to make paper tape of operating web cling to new web surface. When double-faced adhesive tape of new web arrives position below foam roll, the paper tape of new and operating web will be spliced, and the finished web will be cut off by splicer knife.     随后接纸机的接纸臂部件和加速臂部件旋转上升并复位，最后接纸机的主轴和转臂开始旋转，直到将新纸卷送至运行工位而停止（此位置机器内部已设定）。Subsequently, the splicing arm part and accelerating arm part spin up and reset, the spindle and tumbler of splicer start to revolve until new web is sent to preset operation station. 至此整个接纸过程完成，而在这个整个过程中印刷主机并没有减速和停止。Thus entire splicing process is accomplished without slow down or stop of principal printing machine.

用完的卷筒并装载另一个新卷筒纸，准备下一个自动接纸。The finished web is unloaded and a new one is loaded to prepare next automatic splicing.
