一种用送纸主轴的角度位置控制印刷单元着墨机构的方法A Method of Controlling the Inking Mechanism of a Printing Unit Using the Angular Position of the Paper Feed Main Shaft

技术领域:Technical field:

本发明涉及一种纸箱印刷机械领域,具体涉及印刷机的印刷单元的着墨控制方法。The invention relates to the field of carton printing machinery, in particular to an inking control method of a printing unit of a printing machine.

背景技术:Background technique:

在纸箱印刷机械中,会配置多个印刷单元,通过每一个印刷单元的套色印刷,才能印刷出鲜艳精美的图案。在每一个印刷单元的着墨机构里装有一条用来上墨的网纹辊,该着墨机构可以控制网纹辊上升、下降来控制网纹辊与印版接触或者脱离,来实现着墨印刷或者不着墨停止印刷。纸箱印刷机械在不印刷工作和停止印刷的时候,网纹辊应脱离印版不着墨,否则印版重复着墨会使印版的着墨厚度增加,图案颜色加深,与正常印刷时的印刷图案不一致。由于一台纸箱印刷机是由多个印刷单元组成,从第一组印刷单元开始进入印刷到第二组……直至最后一组印刷单元,每一组印刷单元启动印刷的时间是不同的,这就需要设定每一组开始进入印刷的时间,来确定网纹辊开始对印版的着墨时间。同样当印刷停止时网纹辊也要按一定的时间顺序脱离印版停止着墨。In the carton printing machine, multiple printing units will be configured, and only through the color printing of each printing unit can the bright and exquisite patterns be printed. An anilox roller for inking is installed in the inking mechanism of each printing unit. The inking mechanism can control the rise and fall of the anilox roller to control the contact or separation between the anilox roller and the printing plate to achieve inking printing or not. Inking stops printing. When the carton printing machine is not printing and stops printing, the anilox roller should be separated from the printing plate and not inked, otherwise the repeated inking of the printing plate will increase the inking thickness of the printing plate and deepen the color of the pattern, which is inconsistent with the printed pattern during normal printing. Since a carton printing machine is composed of multiple printing units, from the first group of printing units to the second group... until the last group of printing units, each group of printing units starts printing at different times, which means It is necessary to set the time when each group starts printing to determine the time when the anilox roller starts to ink the printing plate. Similarly, when the printing stops, the anilox roller should also be detached from the printing plate in a certain time sequence to stop inking.

目前的着墨机构对网纹辊开始着墨和脱离印版的控制方法,是依据机器的转速来估算纸板的传输位置,然后控制着墨机构下降,网纹辊与印版接触着墨。由于在印刷生产的复杂工作环境中,着墨位置与纸板的传输到达的位置很难准确配合控制,会出现着墨机构下降着墨过早或延滞,而造成最先印刷的几张纸板图案颜色浓厚或浅薄。同时,着墨机构每次下降与印版接触着墨的位置由于不能常常保证在印版的起始位置也造成纸板图案有半深半浅的色差,造成开始印刷的前几张纸板报废。The current control method of the inking mechanism for the anilox roller to start inking and leave the printing plate is to estimate the transmission position of the cardboard according to the speed of the machine, and then control the inking mechanism to descend, so that the anilox roller contacts the printing plate for inking. Because in the complex working environment of printing production, it is difficult to accurately control the inking position and the arrival position of the cardboard, and the inking mechanism will drop prematurely or delay the inking, resulting in thick or shallow color of the first few printed cardboard patterns . Simultaneously, every time the inking mechanism descends and touches the inking position of the printing plate, because the starting position of the printing plate cannot always be guaranteed, the cardboard pattern has half-dark and half-light color difference, causing the first few sheets of cardboard to be printed to be scrapped.

另外在采用进行计数批次模式生产时,即每计数到设置张数(批次)就停顿送纸一次,然后再启动送纸自动循环计数进行下一批次的印刷,如此循环的启停送纸工作,加上着墨控制的非准确性常使每次送纸印刷时最先印刷的几张纸板图案颜色和后续纸板印刷图案的效果不一致,而使得该模式得不到非常好的应用。In addition, when using the counting batch mode for production, that is, every time the set number of sheets (batch) is counted, the paper feeding will be stopped once, and then the automatic cycle counting of paper feeding will be started to print the next batch. Paper work, coupled with the inaccuracy of ink control, often makes the color of the first few cardboard patterns printed on each paper feeding printing and the effect of subsequent cardboard printing patterns inconsistent, so that this mode cannot be used very well.

发明内容:Invention content:

本发明的目的是提供一种可以在印刷过程中依据送纸主轴的旋转角度位置来精确计算纸板的实时传输位置,并同时精准控制每个印刷单元的着墨机构在各自印版的起始位置开始着墨或脱离印版,不受机器转速的影响,提高成品率和生产效率,降低生产成本的纸箱印刷机印刷着墨控制方法。The purpose of the present invention is to provide a method that can accurately calculate the real-time transmission position of the cardboard according to the rotation angle position of the paper feeding spindle during the printing process, and at the same time accurately control the inking mechanism of each printing unit to start at the initial position of the respective printing plate Inking or detaching from the printing plate is not affected by the speed of the machine, which improves the yield and production efficiency and reduces the production cost of the carton printing machine printing ink control method.

本发明的目的可以通过以下技术方案来实现:一种用送纸主轴的角度位置控制印刷单元着墨机构的方法包括:送纸伺服驱动器模块、光耦转换模块。The object of the present invention can be achieved through the following technical solutions: A method for controlling the ink striking mechanism of a printing unit by using the angular position of the paper feeding spindle includes: a paper feeding servo driver module and an optocoupler conversion module.

本发明的控制方法的实现步骤:The implementation steps of the control method of the present invention:

步骤1.本发明是利用伺服控制系统的高精度和高动态响应的优点实现上述的控制,根据弧长公式和圆心角度计算公式预先算出与各印刷单元着墨位置对应的角度脉冲值,每一组定制的角度脉冲值与纸板传输位置及每个印刷单元印版的着墨位置都一一对应。然后将这些脉冲值编辑在送纸主轴的伺服驱动器模块的角度位置触发功能表中,并设置触发输出对应的输出端子地址,通过输出端子连线到各对应印刷单元的光耦转换模块,光耦转换模块连线控制本单元着墨机构的气缸电磁阀。Step 1. The present invention utilizes the advantages of high precision and high dynamic response of the servo control system to realize the above-mentioned control, and pre-calculates the angle pulse value corresponding to the inking position of each printing unit according to the arc length formula and the circle center angle calculation formula, and each group The customized angular pulse value corresponds to the position of the carton transport and the inking position of the printing plate of each printing unit. Then edit these pulse values in the angle position trigger function table of the servo driver module of the paper feeding spindle, and set the output terminal address corresponding to the trigger output, and connect the output terminal to the optocoupler conversion module of each corresponding printing unit, the optocoupler The conversion module is wired to control the cylinder solenoid valve of the unit's inking mechanism.

步骤2.当开始送纸时,第一张纸板从送纸主轴的零点(0°)送出,到达第一印刷单元的印刷位置时,此时在印刷辊筒上的印版的起始位置(无印刷区域R)也正旋转到与网纹辊接触的位置区域,同时送纸主轴也刚好旋转到该单元对应的触发角度位置,并触发该单元的着墨机构在印版起始位置(无印刷区域R)开始下降接触着墨。Step 2. When the paper feeding starts, the first cardboard is sent out from the zero point (0°) of the paper feeding spindle, and when it reaches the printing position of the first printing unit, the starting position of the printing plate on the printing cylinder at this time ( The non-printing area R) is also rotating to the position area in contact with the anilox roller, and at the same time, the paper feeding spindle just rotates to the trigger angle position corresponding to the unit, and triggers the inking mechanism of the unit to be at the starting position of the printing plate (no printing Area R) begins to drop contact inking.

步骤3.当送纸主轴继续旋转到下一个单元(印刷二单元)对应的定制触发角度时,会按上述方式依次对应触发该印刷单元的着墨机构在印版起始位置(无印刷区域R)在气缸带动下开始下降,网纹辊与粘挂在印版辊上的印版接触着墨,直到触发完成该机器配置的最后一个印刷单元的着墨机构下降为止,所有参与印刷的单元着墨机构在下降后,会一直保持在着墨位置工作,使第一张纸板的着墨量与后续的纸板保证一样,从而确保最先印刷的纸板的图案颜色效果与后续的一致。Step 3. When the paper feeding spindle continues to rotate to the customized triggering angle corresponding to the next unit (printing unit 2), the inking mechanism of the printing unit will be triggered in sequence according to the above method to be at the starting position of the printing plate (no printing area R) Driven by the cylinder, it begins to descend, and the anilox roller contacts the printing plate attached to the printing plate roller for inking, until the inking mechanism of the last printing unit that triggers the completion of the machine configuration is lowered, and all the inking mechanisms of the printing units are descending After that, it will keep working at the inking position, so that the amount of ink on the first cardboard is guaranteed to be the same as that of the subsequent cardboards, so as to ensure that the pattern color effect of the first printed cardboard is consistent with that of the subsequent ones.

步骤4.当结束送纸时,送纸主轴旋转到定制的触发上升的角度位置,依次在印版起始位置(无印刷区域R)触发上升印刷(一单元)的着墨机构,由气缸带动着墨机构上升,网纹辊与粘挂在印刷版辊上的印版脱离,而此时最后一张纸板刚好完成印刷并进入到下一单元(印刷二单元)。同样,该单元(印刷二单元)也按上一单元相同的方法完成印刷的同时,也依次对应触发上升着墨机构脱离印版,按此步骤顺序控制,直到纸板完成所有印刷并触发最后一个印刷单元的着墨机构上升脱离印版停止着墨印刷为止。这样就保证了最后一张纸板的着墨效果与之前印刷的纸板完全相同,由于印刷生产的启动、停止都周而复始按上述的步骤来进行顺序控制,因此确保整个生产中所有的纸板印刷图案无论第一张和最后一张都保持品质一致。Step 4. When the paper feeding is finished, the paper feeding spindle rotates to the customized angle position to trigger the rising, and in turn triggers the inking mechanism of rising printing (one unit) at the starting position of the printing plate (no printing area R), and the inking mechanism is driven by the cylinder The mechanism rises, and the anilox roller separates from the printing plate stuck on the printing plate roller. At this time, the last cardboard just finishes printing and enters the next unit (printing unit 2). Similarly, this unit (printing unit 2) completes printing in the same way as the previous unit, and at the same time triggers the ascending inking mechanism to break away from the printing plate, and controls in sequence until the cardboard completes all printing and triggers the last printing unit The inking mechanism rises away from the printing plate until it stops inking and printing. In this way, the inking effect of the last cardboard is guaranteed to be exactly the same as that of the previous printed cardboard. Since the start and stop of printing production are controlled in sequence according to the above steps, it is ensured that all the cardboard printing patterns in the whole production are printed regardless of the first printing. The first and the last one are of the same quality.

一种用送纸主轴的角度位置控制印刷单元着墨机构的方法适用于上印形式的纸箱印刷机,同时也适用下印式纸箱印刷机,当采用下印式印刷形式时,网纹辊在印版辊的下方,压印辊在印版辊的上方。A method of controlling the inking mechanism of the printing unit by the angular position of the paper feeding spindle is suitable for the carton printing machine of the upper printing type, and also suitable for the lower printing type carton printing machine. Below the plate roll, the embossing roll is above the plate roll.

采用本技术方案后,本发明的有益效果是:可以在印刷过程中依据送纸主轴的旋转角度位置来精确计算纸板的实时传输位置,并同时精准控制每个印刷单元的着墨机构在各自印版的起始位置开始着墨或脱离印版,从而保证前后纸板印刷图案颜色一致、达到提高纸板印刷质量和降低印刷成本的目的。After adopting this technical solution, the beneficial effect of the present invention is: the real-time transmission position of the cardboard can be accurately calculated according to the rotation angle position of the paper feeding spindle during the printing process, and at the same time, the inking mechanism of each printing unit can be precisely controlled on each printing plate. The initial position of the cardboard starts to be inked or detached from the printing plate, so as to ensure that the color of the printed pattern on the front and rear cardboards is consistent, and achieve the purpose of improving the quality of cardboard printing and reducing printing costs.

具体实施方法:Specific implementation method:

下面结合附图及实施例对本发明作进一步描述。The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

参见图1——图5所示,一种用送纸主轴的角度位置控制印刷单元着墨机构的方法,本发明的实施有以下步骤:Referring to Fig. 1-shown in Fig. 5, a kind of method with the angular position control printing unit inking mechanism of paper feeding spindle, the implementation of the present invention has the following steps:

步骤一:参见图2、图3利用伺服控制系统的高精度和高动态响应的优点实现上述的控制,根据弧长公式得到:纸板(4)在机器内传输的距离就是送纸主轴(5)旋转的弧长。将每个印刷单元与送纸单元的绝对距离折算为对应的主轴旋转角度脉冲值,编辑到送纸主轴驱动器内的角度位置触发表,使表中每一组定制的角度脉冲值与纸板传输位置及每个印刷单元印版的着墨位置都一一对应,并激活应用该表功能。在伺服驱动器内部设置每个触发输出对应的输出端子地址,每个输出端子就是一个控制源,将控制源信号线连接到对应的印刷单元的光耦模块,印刷单元的光耦模块输出连线控制着墨机构中的电磁阀。Step 1: Refer to Figure 2 and Figure 3 to realize the above-mentioned control by using the advantages of high precision and high dynamic response of the servo control system. According to the arc length formula, the distance that the cardboard (4) is transported in the machine is the paper feeding spindle (5) The arc length of the rotation. The absolute distance between each printing unit and the paper feeding unit is converted into the corresponding spindle rotation angle pulse value, and edited into the angle position trigger table in the paper feeding spindle driver, so that each group of customized angle pulse values in the table is related to the cardboard transmission position And the inking position of each printing unit's printing plate is one-to-one, and activate the function of applying the table. Set the output terminal address corresponding to each trigger output inside the servo drive, each output terminal is a control source, connect the control source signal line to the corresponding optocoupler module of the printing unit, and the output connection of the optocoupler module of the printing unit is controlled Solenoid valve in the inking mechanism.

弧长公式和圆心角度计算公式如下:The arc length formula and the calculation formula of the center angle are as follows:

弧长公式:L=n×π×r/180Arc length formula: L=n×π×r/180

送纸主轴的圆心角度n=360×L/CThe center angle of the paper feeding spindle n=360×L/C

注:n——送纸主轴圆心角度Note: n——The angle of the center of the paper feeding spindle

L——送纸主轴的圆心角对应的弧长L——The arc length corresponding to the central angle of the paper feeding spindle

C——印刷辊的周长C - the circumference of the printing roller

r——印刷辊的半径r - the radius of the printing roller

步骤二:参见图1、图2、图3、图4机器印刷生产开始,当纸板(4)传输到达(印刷一单元)印刷位置时,送纸主轴(5)也正好旋转到达表中定制的(印刷一)触发下降角度位置,就输出信号触发激活输入信号(POS_SWITCH.1)为on状态,并在条件信号(送纸使能)为on状态时,则对应的输出信号(P1_A1)立即激活输出,印刷单元的着墨机构(6)结合本单元的运行条件(印刷使能)判断是否执行该控制指令,若条件信号(印刷使能)为on状态,则执行控制指令触发光电耦合模块的输出信号控制本单元的气缸(8)带动着墨机构(6)在印版(1)的起始位置(无印刷区域R)下降,网纹辊(7)与粘挂在印刷版辊(2)上的印版(1)接触着墨,如图4所示状态。若本单元的条件信号(印刷使能)为off状态时,则不执行使能着墨机构的控制指令,直接跳转到下一单元(印刷二单元)去执行。Step 2: Refer to Figure 1, Figure 2, Figure 3, and Figure 4. The printing production of the machine starts. When the cardboard (4) is transported to the printing position (printing unit 1), the paper feeding spindle (5) also rotates to reach the customized position in the table. (Printing 1) When the position of the falling angle is triggered, the output signal triggers and activates the input signal (POS_SWITCH.1) is on, and when the conditional signal (paper feed enable) is on, the corresponding output signal (P1_A1) is activated immediately Output, the inking mechanism (6) of the printing unit judges whether to execute the control command in combination with the operating conditions (printing enable) of the unit. If the condition signal (printing enable) is on, the control command is executed to trigger the output of the photoelectric coupling module The signal controls the cylinder (8) of this unit to drive the inking mechanism (6) to descend at the starting position (no printing area R) of the printing plate (1), and the anilox roller (7) is stuck on the printing plate roller (2) The printing plate (1) is in contact with ink, as shown in Figure 4. If the conditional signal (printing enable) of this unit is off, the control command for enabling the inking mechanism will not be executed, and it will directly jump to the next unit (printing unit 2) for execution.

步骤三:当纸板(4)在印版辊(2)、底压辊(3)的传送下经过印刷一到达印刷二单元的印刷位置的同时,送纸主轴(5)也同时旋转到达印刷二单元触发着墨机构(6)下降的角度位置,并输出信号触发激活输入信号(POS_SWITCH.2)为on状态,同时在条件连锁信号(P1_A1)为on状态时,则对应的输出信号(P2_A1)立即激活输出,在本单元的条件信号(印刷使能)为on状态下,执行该指令去触发光电耦合模块的输出信号控制本单元的气缸(8)带动着墨机构(6)在印版(1)的起始位置(无印刷区域R)下降,网纹辊(7)与粘挂在印刷版辊(2)上的印版(1)接触着墨,,也如图4所示状态。如若本单元的条件信号(印刷使能)为off状态时,则直接跳转到下一单元(印刷三单元)去执行指令。同样,后续的印刷单元也按上述步骤操作,直到触发该机器配置的最后一个印刷单元的着墨机构(6)下降着墨为止。然后,所有参与印刷的单元着墨机构(6)在下降后,会一直保持在着墨位置工作,使所有印刷制品无论前后其着墨量和图案颜色效果都是一致的。Step 3: When the cardboard (4) is conveyed by the printing plate roller (2) and the bottom pressure roller (3) and reaches the printing position of the printing unit 2 at the same time, the paper feeding spindle (5) also rotates to reach the printing position of the printing unit 2 The unit triggers the falling angle position of the inking mechanism (6), and outputs a signal to trigger the activation input signal (POS_SWITCH.2) to be on. At the same time, when the condition chain signal (P1_A1) is on, the corresponding output signal (P2_A1) immediately Activate the output. When the conditional signal (printing enable) of this unit is on, execute this instruction to trigger the output signal of the photoelectric coupling module to control the cylinder (8) of this unit to drive the inking mechanism (6) on the printing plate (1) The initial position (non-printing area R) descends, and the anilox roller (7) is in contact with the printing plate (1) attached to the printing plate roller (2), and the state is also shown in Figure 4. If the conditional signal (printing enable) of this unit is off, it will directly jump to the next unit (printing unit 3) to execute the instruction. Similarly, subsequent printing units also operate according to the above-mentioned steps until the inking mechanism (6) of the last printing unit configured by the machine is triggered to descend to ink. Then, all the unit inking mechanisms (6) participating in the printing will keep working at the inking position after descending, so that the inking amount and pattern color effect of all printed products are consistent regardless of the front and back.

步骤四:参见图1、图2、图3、图5当机器停止印刷送纸,最后一张纸板(4)在印刷一单元刚好完成印刷并进入到下一单元(印刷二单元)时,送纸主轴(5)准确旋转到表中定制的(印刷一单元)触发上升脱离着墨的角度位置,触发输出信号(POS_SWITCH.1)为off状态,并在条件信号(送纸使能)为off状态时,则复位对应的输出信号(P1_A1),使之为off状态。接着执行复位指令,复位本单元(印刷1)的光电耦合模块的输出信号,使该单元的着墨机构(6)在印版(1)的起始位置(无印刷区域R)由气缸(8)带动着墨机构(6)上升,网纹辊(7)与粘挂在印刷版辊(2)上的印版(1)脱离着墨。如图5所示。Step 4: See Figure 1, Figure 2, Figure 3, and Figure 5. When the machine stops printing and feeding paper, the last piece of cardboard (4) has just finished printing in the first printing unit and enters the next unit (printing second unit). The paper spindle (5) rotates accurately to the angle position customized in the table (printing one unit) to trigger the rise and break away from the ink, the trigger output signal (POS_SWITCH.1) is off, and the condition signal (paper feed enable) is off , then reset the corresponding output signal (P1_A1) to make it off. Then execute the reset command to reset the output signal of the photoelectric coupling module of the unit (printing 1), so that the inking mechanism (6) of the unit is at the initial position of the printing plate (1) (no printing area R) by the cylinder (8) Drive the inking mechanism (6) to rise, and the anilox roller (7) and the printing plate (1) stuck on the printing plate roller (2) are separated from the ink. As shown in Figure 5.

当本单元的条件信号(印刷使能)为off状态时,则不理会该指令,直接跳转到下一单元(印刷二单元)去执行指令。When the conditional signal (printing enable) of this unit is in the off state, ignore the command and directly jump to the next unit (printing unit 2) to execute the command.

同样的,当送纸主轴(5)旋转到表中定制的下一单元(印刷二单元)的触发上升脱离着墨的角度位置时,最后一张纸板也正刚好完成印刷并进入到下一单元(印刷三单元),就触发输出信号(POS_SWITCH.2)为off状态,同时在连锁条件信号(P1_A1)为off状态,则复位对应的输出信号(P2_A1),使之为off状态。并执行复位指令,复位本印刷单元的光电耦合模块的输出信号,使该单元的着墨机构在印版的起始位置(无印刷区域R)上升脱离着墨。如若本单元的条件信号(印刷使能)为off状态时,则不理会该指令,直接跳转到下一单元(印刷三单元)去执行指令。Similarly, when the paper feed main shaft (5) rotates to the angle position where the next unit (printing unit 2) customized in the table is triggered and rises away from the inking angle position, the last cardboard has just finished printing and enters the next unit ( Print three units), the trigger output signal (POS_SWITCH.2) is off, and at the same time the chain condition signal (P1_A1) is off, then reset the corresponding output signal (P2_A1) to make it off. And execute the reset command to reset the output signal of the photoelectric coupling module of the printing unit, so that the inking mechanism of the unit rises from the initial position of the printing plate (no printing area R) and leaves the ink. If the conditional signal (printing enable) of this unit is off, ignore the command and jump directly to the next unit (printing unit 3) to execute the command.

与此类推,后续的印刷单元也按上述复位步骤操作,直到触发该机器配置的最后一个印刷单元的着墨机构(6)上升脱离着墨为止。在此依据送纸主轴的旋转角度位置来精确计算纸板的实时传输位置,并同时精准控制每个印刷单元的着墨机构(6)在各自印版的起始位置开始着墨或脱离印版的着墨控制方法下,每次的印刷生产都能确保纸板的图案颜色和效果始终保持一致,从而达到提高纸板印刷质量、生产效率和降低成本的目的。By analogy, subsequent printing units also operate according to the above-mentioned resetting steps, until the inking mechanism (6) of the last printing unit configured by the machine is triggered to rise and break away from inking. Here, the real-time conveying position of the cardboard is accurately calculated according to the rotation angle position of the paper feeding spindle, and at the same time, the inking mechanism (6) of each printing unit is precisely controlled to start inking at the starting position of the respective printing plate or to leave the inking control of the printing plate Under the method, each printing production can ensure that the pattern color and effect of the cardboard are always consistent, so as to achieve the purpose of improving the printing quality of the cardboard, production efficiency and reducing costs.

The present invention utilizes the advantages of high precision and high dynamic response of the servo control system to realize the above-mentioned control, and pre-calculates the angle pulse value corresponding to the inking position of each printing unit according to the arc length formula and the circle center angle calculation formula, and each group The customized angular pulse value corresponds to the position of the carton transport and the inking position of the printing plate of each printing unit. Then edit these pulse values in the angle position trigger function table of the servo driver module of the paper feeding spindle, and set the output terminal address corresponding to the trigger output, and connect the output terminal to the optocoupler conversion module of each corresponding printing unit, the optocoupler The conversion module is wired to control the cylinder solenoid valve of the unit's inking mechanism. 步骤2.当开始送纸时,第一张纸板从送纸主轴的零点(0°)送出,到达第一印刷单元的印刷位置时,此时在印刷辊筒上的印版的起始位置(无印刷区域R)也正旋转到与网纹辊接触的位置区域,同时送纸主轴也刚好旋转到该单元对应的触发角度位置,并触发该单元的着墨机构在印版起始位置(无印刷区域R)开始下降接触着墨。Step 2. When the paper feeding starts, the first cardboard is sent out from the zero point (0°) of the paper feeding spindle, and when it reaches the printing position of the first printing unit, the starting position of the printing plate on the printing cylinder at this time ( The non-printing area R) is also rotating to the position area in contact with the anilox roller, and at the same time, the paper feeding spindle just rotates to the trigger angle position corresponding to the unit, and triggers the inking mechanism of the unit to be at the starting position of the printing plate (no printing Area R) begins to drop contact inking. 步骤3.当送纸主轴继续旋转到下一个单元(印刷二单元)对应的定制触发角度时,会按上述方式依次对应触发该印刷单元的着墨机构在印版起始位置(无印刷区域R)在气缸带动下开始下降,网纹辊与粘挂在印版辊上的印版接触着墨,直到触发完成该机器配置的最后一个印刷单元的着墨机构下降为止,所有参与印刷的单元着墨机构在下降后,会一直保持在着墨位置工作,使第一张纸板的着墨量与后续的纸板保证一样,从而确保最先印刷的纸板的图案颜色效果与后续的一致。Step 3. When the paper feeding spindle continues to rotate to the customized triggering angle corresponding to the next unit (printing unit 2), the inking mechanism of the printing unit will be triggered in sequence according to the above method to be at the starting position of the printing plate (no printing area R) Driven by the cylinder, it begins to descend, and the anilox roller contacts the printing plate attached to the printing plate roller for inking, until the inking mechanism of the last printing unit that triggers the completion of the machine configuration is lowered, and all the inking mechanisms of the printing units are descending After that, it will keep working at the inking position, so that the amount of ink on the first cardboard is guaranteed to be the same as that of the subsequent cardboards, so as to ensure that the pattern color effect of the first printed cardboard is consistent with that of the subsequent ones. 步骤4.当结束送纸时,送纸主轴旋转到定制的触发上升的角度位置,依次在印版起始位置(无印刷区域R)触发上升印刷(一单元)的着墨机构,由气缸带动着墨机构上升,网纹辊与粘挂在印刷版辊上的印版脱离,而此时最后一张纸板刚好完成印刷并进入到下一单元(印刷二单元)。同样,该单元(印刷二单元)也按上一单元相同的方法完成印刷的同时,也依次对应触发上升着墨机构脱离印版,按此步骤顺序控制,直到纸板完成所有印刷并触发最后一个印刷单元的着墨机构上升脱离印版停止着墨印刷为止。这样就保证了最后一张纸板的着墨效果与之前印刷的纸板完全相同,由于印刷生产的启动、停止都周而复始按上述的步骤来进行顺序控制,因此确保整个生产中所有的纸板印刷图案无论第一张和最后一张都保持品质一致。Step 4. When the paper feeding is finished, the paper feeding spindle rotates to the customized angle position to trigger the rising, and in turn triggers the inking mechanism of rising printing (one unit) at the starting position of the printing plate (no printing area R), and the inking mechanism is driven by the cylinder The mechanism rises, and the anilox roller separates from the printing plate stuck on the printing plate roller. At this time, the last cardboard just finishes printing and enters the next unit (printing unit 2). Similarly, this unit (printing unit 2) completes printing in the same way as the previous unit, and at the same time triggers the ascending inking mechanism to break away from the printing plate, and controls in sequence until the cardboard completes all printing and triggers the last printing unit The inking mechanism rises away from the printing plate until it stops inking and printing. In this way, the inking effect of the last cardboard is guaranteed to be exactly the same as that of the previous printed cardboard. Since the start and stop of printing production are controlled in sequence according to the above steps, it is ensured that all the cardboard printing patterns in the whole production are printed regardless of the first printing. The first and the last one are of the same quality. 3.根据权利要求1所述的一种用送纸主轴的角度位置控制印刷单元着墨机构的方法适用于上印形式的纸箱印刷机,同时也适用下印式纸箱印刷机,当采用下印式印刷形式时,网纹辊在印版辊的下方,压印辊在印版辊的上方。3.
