Description

一种基于烟支数据探测的接装纸在线打孔结构及方法 技术领域
本发明涉及烟支制备技术领域，尤其是，本发明涉及一种基于烟支数据探测的接装纸在线打孔结构及方法。
 背景技术
烟用材料，主要是“三纸一棒”（卷烟纸、接装纸、成形纸、滤棒）直接决定了卷烟的物理参数，影响着卷烟的燃烧状态，对卷烟外观质量以及主流烟气成分、感官品质等重要起到关键的作用，是卷烟生产中对烟气指标的主要管控方式之一，其按作用机理可分为卷烟纸燃烧端及滤棒过滤端。烟用材料一定程度上决定了常规卷烟的燃烧状态，并通过过滤及稀释作用影响主流烟气成份配比，最终影响烟气的感官质量。通过烟用材料参数的设计与配比，是改善卷烟烟气指标及感官质量最为直接与简便的常规技术途径之一。烟用材料一定程度上决定了常规卷烟的燃烧状态，并通过过滤及稀释作用影响主流烟气成份配比，最终影响烟气的感官质量。通过烟用材料参数的设计与配比，是改善卷烟烟气指标及感官质量最为直接与简便的常规技术途径之一。
接装纸通风的实现方式有两种：在线打孔和预打孔。生产上多采用预打孔的方式，即用打孔接装纸（静电打孔或激光打孔）来接装由高透成形纸卷制的高透滤棒和烟条。通过采用滤棒通风来稀释或降低主流烟气，进而达到降焦的目的，目前接装纸打孔为线性周向打孔，一般打孔孔带控制在1-5排，每排根据卷烟直径不同可打10-25个孔。
另外目前激光在线打孔机制单一机械，仅仅设置激光打孔的功率和时间，用于将接装纸和成形纸打穿，例如中国专利发明专利CN101862910A公开了一种卷烟接装纸并行式激光打孔方法，将K路并行排列的脉冲激光器组成的激光器阵列输出的K路脉冲激光束，经光路变换系统耦合传输后，聚焦于连续运动的水松纸的表面，形成沿水松纸宽度方向呈直线形或斜线形密集排列的K路打孔脉冲激光；藉由水松纸在线速度检测系统对水松纸的运动速度进行实时检测，并将其速度信息反馈到控制系统，再通过控制系统发出控制信号对所述激光器阵列中各脉冲激光器的出光时序、脉冲频率以及脉冲间隔时间进行控制，配合水松纸的连续运动，在水松纸表面打出图形或字符排列分布的小孔，其中K=2~10。上述发明同时提供了一种实现上述方法的装置，所述装置结构简单、工作稳定、加工效率高。
 技术问题
但是上述激光打孔方法依然存在以下问题：在接装纸上打孔时，由于不同的烟支位置不尽不相同，根据滤棒成形纸层数不同，接装纸搭口位置不同，以最极端的三元复合滤棒卷烟打孔为例，打孔位置在接装纸搭口位置，如果滤棒基棒成形纸搭口位置、一次复合成形机搭口位置、二次复合成形纸搭口位置全部位于同位置，接装纸在线打孔需要打穿8层纸，而其它位置只需要打穿4层纸张，由于激光打孔设备功率相同，需要打穿的纸张层数界于4-8之间。因打孔位置不固定，有的位置纸张层数较多，可能纸张没有打通，而无法实现通风效果。根据搭口宽度2mm占卷烟圆周的比例，细支卷烟圆周17mm、中支卷烟圆周20mm、常规支卷烟圆周24mm，如果搭口位置没有打孔一般会影响通风率10%左右，从而造成焦油和感官质量的较大波动；另外无法探测滤棒内部丝束填充性，无法根据内部丝束松紧程度差异进行动态变化。
因此为了解决上述问题，设计一种合理高效的基于烟支数据探测的接装纸在线打孔结构对我们来说是很有必要的。
 技术解决方案
本发明的目的在于提供一种设置简单，通过加装探测头，用于获取接装纸和成形纸的材质、厚度以及层数，实时将纸张数据反馈至激光打孔部，激光打孔部根据需要调节功率，有效保证接装纸和成形纸打穿，且可以根据丝束松紧度，来调节激光打孔功率，确保烟支通风率，适用于不同的烟支进行打孔操作的基于烟支数据探测的接装纸在线打孔结构。

对于相关领域普通技术人员已知的技术、方法及系统可能不作详细讨论，但在适当情况下，技术、方法及系统应当被视为授权说明书的一部分。
实施例一：如图1、2所示，仅仅为本发明的其中一个的实施例，一种基于烟支数据探测的接装纸在线打孔结构，包括烟支成形部4、烟支接装部5、分切部6、设置于所述烟支接装部5与分切部6之间的传送部7、设置于所述传送部7上方的激光打孔部8、设置于所述烟支成形部4侧面用于获取成形纸材质的第一探测头1、设置于所述烟支接装部5侧面用于获取接装纸材质的第二探测头2、设置于所述传送部7处的第三探测头3，所述第三探测头3包括同位素扫描仪31和红外探头32，所述激光打孔部8包括激光输出头81以及与所述激光输出头81电连接的功率控制器82，所述同位素扫描仪31设置于所述传送部7上的烟支的轴向延伸方向上，且所述第一探测头1和第二探测头2均与所述同位素扫描仪31电连接，所述红外探头32和激光输出头81均设置于所述传送部7上的烟支的径向延伸方向上，所述红外探头32和同位素扫描仪31均与所述功率控制器82电连接。
在本发明中，烟支的生产过程为：烟支丝束和滤棒在烟支成形部4处包裹成形纸；然后输送至烟支接装部5进行接装，烟支接装部5中，接装纸从盘纸装置引出，穿过接装纸自动接纸器、供纸辊和上胶装置后，在接装纸切割鼓轮切割成片，送至靠拢鼓轮后，粘合在包裹成形纸的烟支外侧，并进行搓接和加热干燥，使得接装纸胶液熨干；最后接装完成的烟支经过传送部7运送至分切部6进行分切，得到后续的生产烟支；而激光打孔部8设置于传送部7上方用于在烟支的外侧环绕打孔。
在本实施例中，所述烟支成形部4侧面设置有用于获取成形纸材质的第一探测头1，所述烟支接装部5侧面设置有用于获取接装纸材质的第二探测头2，所述传送部7处设置有第三探测头3，其中所述第三探测头3包括同位素扫描仪31和红外探头32，又有所述激光打孔部8包括激光输出头81以及与所述激光输出头81电连接的功率控制器82。
那么烟支成形部4处烟支成形时，第一探测头1可以获取成形纸的材质，并发送至同位素扫描仪31；烟支接装部5处烟支接装时，第二探测头2可以获取接装纸的材质，并发送至同位素扫描仪31；烟支到达传送部7上在激光打孔部8打孔之前，同位素扫描仪31拍摄烟支横截面图像，并根据之前获取的成形纸和接装纸的材质，通过不同材质的表面积的分布，可以知道成形纸和接装纸的厚度和层数，反馈至功率控制器82，功率控制器82生成相应的功率参数发送至激光输出头81，激光输出头81对烟支10侧面进行激光打孔，形成激光孔101。
另外，第三探测头3的红外探头32实时对激光孔101处进行温度探测，防止激光打孔时温度过高，对烟支内的烟丝丝束造成灼烧，影响卷烟的抽吸质感，在这里，成形纸和接装纸与丝束灼烧温度是不一样的，红外探头32就是对打孔处的温度进行实时探测，一旦烟丝丝束造成灼烧，那么就发送信号至功率控制器82，修正激光打孔参数，即降低激光输出头81的输出功率；反之则是成形纸和接装纸在激光灼烧打孔，不发送任何修正信号。
当然，激光孔101是横向环绕烟支10设置的，即烟支可以进行旋转，从而进行环绕打孔，且有时候还打多排激光孔（如图2所示），此时不同位置的纸张分布和层数不一，同位素扫描仪31获取的是靠近激光输出头81的一侧的纸张参数，然后发送至功率控制器82；并在卷烟旋转过程中，多次重复上述操作。
这样，不论是接装纸处、接装纸加成形纸叠加处还是接装纸搭口处，因为纸张的层数分布的不同，从而确保纸张打穿，却又不会灼烧烟丝，有效确保了烟支通风率。
需要注意的是，所述烟支成形部4侧面还设置有用于获取烟支丝束材质的第四探测头9，所述第四探测头9设置于所述烟支成形部4上的烟支的轴向延伸方向上；也就是在烟支成形时，第四探测头9获取烟支内丝束材质，并发送至同位素扫描仪31；同位素扫描仪31进行成像扫描时，也会根据丝束的材质生成该材质的表面积分布图，即可以获取到烟丝填充在成形纸内侧的填充紧实度（也可以说是密度），发送至功率控制器82；功率控制器82根据烟丝丝束紧实度，来适当的修正激光输出头81的输出功率。
一般来说，烟支丝束紧实的话，过滤面积相对小一些，那么激光输出头81的输出功率需要高一些，提高此部位的通风效果，增大通风率；反之丝束松散的话，过滤面积大，那么激光输出头81的输出功率低一些，减小此部分的通风效果，从而实现不同松紧程度丝束通风率的稳定。
本发明一种基于烟支数据探测的接装纸在线打孔结构的设置简单，通过加装探测头，用于获取接装纸和成形纸的材质、厚度以及层数，实时将纸张数据反馈至激光打孔部，激光打孔部根据需要调节功率，有效保证接装纸和成形纸打穿，且可以根据丝束松紧度，来调节激光打孔功率，确保烟支通风率，适用于不同的烟支进行打孔操作。
实施例二，仍如图1、2所示，仅为本发明的其中一个实施例，在实施例一的基础上，本发明一种基于烟支数据探测的接装纸在线打孔结构中，所述传送部7上设置有用于将烟支进行夹持和旋转的夹持件，用于防止烟支10乱跑，并旋转烟支进行周向的环绕打孔。
以及，所述激光输出头81的数量至少为一个。
所述激光输出头81数量为一个时，所述夹持件连接设置有用于驱动所述夹持件沿烟支轴向延伸方向移动的伸缩杆，伸缩杆最好是多级伸缩杆，每一次伸缩量就是两排激光孔101之间的距离。
反之，所述激光输出头81的数量至少为两个时，多个所述激光输出头81呈直线排列，且多个所述激光输出头81排列的直线与所述烟支轴向延伸方向平行设置。
最后，所述红外探头32的数量至少为一个，多个红外探头32设置于激光输出头81的周围，且红外探头32与激光输出头81朝向相同，刚好可以观测到激光输出头81打孔处的情形，并对激光输出头81的功率进行修正。
实际上，红外探头32可以直接设置于激光打孔部8前端面上，环绕激光输出头81设置。
实施例三，如图3所示，本发明还提供上述所有实施例中的一种基于烟支数据探测的接装纸在线打孔结构的在线打孔方法，包括以下步骤：
S1：烟支在烟支成形部处成形时，通过第一探测头获取烟支的成形纸的材质；
S2：成形后的烟支经过烟支接装部处粘结接装纸时，通过第二探测头获取烟支的接装纸的材质；
S3：接装完成的烟支经过传送部时，通过设置于烟支轴向延伸方向上的同位素扫描仪对成形纸和接装纸进行扫描，通过步骤S1至S2中获得的成形纸和接装纸的材质，生成成形纸和接装纸的厚度和层数；
S4：设置于传送部上方的激光打孔部中的功率控制器获取到成形纸和接装纸的材质、厚度和层数之后，控制调节激光输出头的输出功率对烟支进行打孔；
S5：通过设置于烟支径向延伸方向上的红外探头获取实时激光打孔图像，对激光输出头的输出功率进行调整；
S6：打孔完毕的烟支经过传送部到达至分切部进行分切。
在这里，在执行步骤S1时，烟支成形部处还通过第四探测头获取烟支内丝束材质；
在执行步骤S3时，同位素扫描仪获取接装纸、成形纸以及丝束的表面积，获取成形纸和接装纸的厚度和层数的同时，还获取丝束紧实度；
在执行步骤S4时，控制器获取丝束紧实度以调节激光输出头的输出功率；
在执行步骤S5时，红外探头还获取打孔处的温度变化，并判断是否发生丝束灼烧，若是则降低激光输出头的输出功率；反之则不执行操作。
本发明一种基于烟支数据探测的接装纸在线打孔结构及方法的设置简单，通过加装探测头，用于获取接装纸和成形纸的材质、厚度以及层数，实时将纸张数据反馈至激光打孔部，激光打孔部根据需要调节功率，有效保证接装纸和成形纸打穿，且可以根据丝束松紧度，来调节激光打孔功率，确保烟支通风率，适用于不同的烟支进行打孔操作。
本发明不局限于上述具体的实施方式，本发明可以有各种更改和变化。凡是依据本发明的技术实质对以上实施方式所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围。
