- the SD value is larger, and the detection value is It also exhibits large fluctuations, and it is difficult to accurately determine the test results of the samples.
- three-sided full-vision detection it can be seen from the SD value that the detection stability is better, and at the same time, due to the full-vision image acquisition, the objectivity and accuracy of the detection results are better.
- the system of the present invention is used to detect the deviation of the ash column more objectively.
- the deviation of the ash column indicates the deviation of the ash column from the axis of the cigarette filter rod during the cigarette burning process.
- the problem caused the measurement of the deviation of the cigarette burning ash column to fail, and it could not accurately indicate the deviation of the entire cigarette burning ash column from the axis of the cigarette filter rod, as shown in Figure 10 (taken with 3 cameras).
- the present invention effectively solves the above-mentioned problems by limiting the relative position angle of the camera and the cigarette for visual collection.
- the cigarette industry does not have a uniform and systematic test method for ash holding performance.
- the commonly used method is to ignite the cigarette and place it horizontally, and observe the ash holding length of the cigarette burning ash column without smoking. Since the above method has no smoking conditions and is based on a static level test, when consumers actually hold the cigarette statically, in order to avoid smoking their fingers, the cigarette will naturally rise at a certain angle. Therefore, the common static test method cannot simulate the consumer's suction action.
- the system of the present invention can realize dynamic detection of ash holding performance, improve the objectivity and accuracy of ash holding performance detection and evaluation, and better guide the development and research of cigarette products.

Description
本发明属于卷烟检测设备技术领域,具体涉及一种基于机械手的抽烟路径仿真系统。
消费者抽吸卷烟是一个动态和静态相结合的过程动作,主要通过手臂完成整个过程动作,通常包括点烟、抽吸、多角度静态持烟、翻转手腕、弹烟灰等典型动作。目前,对卷烟抽吸过程相关指标的检测和研究通常仅引入上述部分典型动作,如:吸烟机包括点烟和抽吸动作,卷烟燃烧锥检测包括点烟、抽吸、弹烟灰动作等,可见,对于卷烟抽吸过程及状态的研究,尚没有包括卷烟抽吸全过程动作和抽吸路径的装置和系统来实现。在对卷烟抽吸过程中,卷烟燃烧锥掉落,包灰性能,飞灰、落灰状态等指标的测定和研究,都与卷烟抽吸全过程动作密切相关。如果仅在部分抽吸动作条件下进行卷烟燃烧指标检测,显然不能实现模拟消费者真实抽吸状态下卷烟实际状态,检测结果缺乏客观性,不能精确地指导相关科研和生产工作,甚至会形成一定的误导。
随着社会经济的发展,生活质量的提升,消费者对卷烟品质的要求也不断提升,消费者在抽吸卷烟过程中,对卷烟燃烧状态关注越来越重视。由于卷烟燃烧状态是消费者能直观捕捉到的产品特征,因此对卷烟燃烧过程中相关指标的研究,一直以来都是卷烟研究工作的重要方向。如何对卷烟燃烧状态及相关指标的准确检测,是指导卷烟研究,优化产品质量升级的关键。
为此,结合实际需求,克服现有技术不足,针对卷烟抽吸全过程特征,开发一整套用于模拟人体抽吸卷烟的仿真系统是卷烟检测技术领域亟需解决的问题。
发明内容
本发明的目的是为了解决现有技术的不足,提供一种可有效模拟真实吸烟动作的基于机械手的抽烟路径仿真系统。
为实现上述目的,本发明采用的技术方案如下:
一种基于机械手的抽烟路径仿真系统,包括机箱,固定设置于机箱内的机械手,以及安装于机械手工作端的烟支夹持器,还包括设置于机箱内位于机械手周边的给料装置、弹烟装置及点烟装置,以及安装于机械手工作端的图像采集装置;

所述的点烟装置包括位于机械手外围的点烟支架,安装于点烟支架上的点烟器;
所述的图像采集装置包括固连于机械手工作端、具有N个支杆的架体,N个分别固连于不同支杆上、且镜头朝向机械手工作端的摄像机,以及N个分别固连于不同支杆上、光源面朝向机械手工作端的补光灯;其中,N≥2。
进一步,优选的是,所述烟支夹持器为管状的橡胶管套。
进一步,优选的是,所述的凹槽为V型槽。
进一步,优选的是,所述的抽烟路径仿真系统还包括位于机械手周边的卸料装置;所述的卸料装置包括装于点烟支架上、用于将烟支拔脱的夹爪和夹爪气缸;夹爪气缸的动力输出端与夹爪连接,用于驱动夹爪夹紧或松开烟支。
进一步,优选的是,所述的抽烟路径仿真系统还包括环境气流检测装置;所述的环境气流检测装置包括安装于机械手工作端处的连接座,以及安装于连接座上、用于采集机械手工作端处烟支运动时空气流速的气流测量传感器;
在对烟支进行检测时,烟支夹持器通过连接座连接在机械手的工作端上;
在测量烟支所在位置的气流时,连接座连接所述气流测量传感器。
进一步,优选的是,在机箱顶端安装有气流调节电机,气流调节电机通过气流管道连接机箱并控制机箱内的气流。
进一步,优选的是,所述的给料装置包括位于机械手外围的整机框架,安装于整机框架上的料斗、料斗驱动电机和烟支转向机构,导向管;
料斗的上部设有能够使水平状态的单支烟通过的通槽,料斗前侧安装有安装面板;
料斗驱动电机与料斗相连,用于驱动料斗旋转,在重力作用下,通过通槽从料斗的待测烟支中获取单支烟下落至烟支转向机构中;
烟支转向机构设在料斗的正下方,上端开口,内设有斜坡,用于将获取的烟支的轴线由水平方向转换为竖直方向;
烟支转向机构内斜坡低端与导向管顶端的入口相连通;
导向管竖直设置。
进一步,优选的是,所述摄像机视场平行于机械手工作端的轴心;补光灯 的光的射线方向垂直于机械手工作端的轴心。
进一步,优选的是,所述机械手携带固连的烟支夹持器从初始位置运动到导向器出口的正下方,使得烟支夹持器的轴心与导向器的轴心重合,烟支通过导向器进入所述烟支夹持器,烟支夹持器夹紧烟支后,机械手模拟消费者在空间的抽烟动作;其中,烟支夹持器轴心与机械手工作端轴心保持一致。
进一步,优选的是,N=3,即摄像机有3个,且以烟支为中心对称设置补光灯有3个,且以烟支为中心对称设置。补光灯与摄像机位置邻近,以保证烟支打光均匀。本发明采用多组摄像头全面采集检测图像,大幅度降低了由于单面采集图像带来的检测数据误差,同时增加了检测有效数据,提升检测效率。
烟支夹持器夹紧烟支后,机械手携带烟支运动到点烟位置,点烟器点燃机械手所携带的烟支;然后,机械手仿真模拟消费者抽吸路径,当需要弹烟时,机械手由抽吸位置运动到弹击位置,驱动电机驱动拔杆对烟支夹持器上的烟支进行弹击,机械手再由弹击位置运动到扶正位置,烟支夹持器上的烟支经支撑板的凹槽进行扶正;接着,重复上述仿真模拟消费者抽吸路径及弹烟、扶正直至抽吸完成(或检测结束);之后,机械手运动到卸料位置,夹爪气缸驱动夹爪夹紧机械手携带的烟支,机械手向夹爪所在方向的反方向运动,烟支从机械手上脱离后,夹爪气缸驱动夹爪松开烟支,完成卸料。其中,机械手由抽吸位置运动到弹击位置过程中,模拟消费者持烟在空间的挥臂摆动和翻手腕动作。
优选的是,机箱内气流控制在150mm/s~250mm/s之间。
本发明与现有技术相比,其有益效果为:
1.提供了一整套模拟人体抽吸卷烟过程动作,包括点烟、抽吸、多角度静态持烟、翻转手腕、弹烟灰等全部典型动作的抽烟路径仿真系统;
2.提供了在模拟不同环境条件下,仿真人体卷烟抽吸动作,对卷烟燃烧过程状态,包括卷烟包灰性能、碳线质量、多角度持灰率等性能指标的检测,提升检测结果的客观性和准确性,检测结果更加精确可信,能有效指导卷烟研究开发工作,优化产品质量升级;
3、本发明通过机械手、给料装置、弹烟装置、点火装置、卸料装置、环境模拟装置、抽吸装置、图像采集装置等功能单元系统集成,实现了在模拟人体卷烟抽吸动作路径条件下的全自动连续检测,重复性好,确保每次模拟动作路径的一致性,有效提高卷烟燃烧特性指标检测的精度;
4、实现了对卷烟燃烧过程中图像的全视觉实时采集,避免了由于单面拍照 采集图像,导致检测结果缺少客观性和准确性,大幅度提升了检测结果的精确度,为指导产品技术研发和生产优化提供准确的数据支持;表1和图9是对检测指标改进的举例说明。
由表1数据可以看出,对于同一平行样品进行灰裂指数(灰柱裂痕部分面积除以灰柱整体面积×100%)检测,采用单面拍摄检测设备进行检测,SD值较大,检测值也呈现出较大波动,难以对样品检测结果进行准确判定。采用三面全视觉检测,从SD值可以看出检测稳定性较好,同时,由于全视觉图像采集,检测结果客观性和精确度更好。
表1各平行样品不同检测方法卷烟灰裂指数检测值
由图9数据检测结果和相应采集图像可以看出,如果采用单面拍摄,由于拍摄角度受限,很难实现对卷烟灰柱偏离度进行准确检测和评价;
5、采用本发明系统对灰柱偏离情况检测更为客观,灰柱偏离表示的是卷烟燃烧过程中灰柱偏离卷烟滤棒轴心的情况,如果从其他视角平面进行单一图像采集,会由于视觉问题从而引起卷烟燃烧灰柱偏离度的测定失败,不能正确表示出整个卷烟燃烧灰柱偏离卷烟滤棒轴心的程度,如图10所示(采用3个摄像机拍摄)。本发明通过限定摄像与烟支的相对位置视角进行视觉采集的方法有效解决了上述难题。
6、目前,卷烟行业对持灰性能的考察没有较为统一和系统的测试方法,常用的方法是将卷烟点燃后水平放置,在没有抽吸条件下观察卷烟燃烧灰柱持灰长度。上述方法由于没有抽吸条件,且基于静态水平测试,而消费者在实际静态持烟时,为了避免烟熏手指,都会让卷烟自然上翘呈一定角度。所以,常见的静态测试方法不能模拟消费者抽吸动作。采用本发明系统可实现对持灰性能 的动态检测,提高了持灰性能检测和评价的客观性和精确度,更好地指导卷烟产品开发研究工作。

烟支夹持器3夹紧烟支后,机械手2携带烟支21运动到点烟位置,点烟器13点燃机械手2所携带的烟支21;然后,机械手2仿真模拟消费者抽吸路径,当需要弹烟时,机械手2由抽吸位置运动到弹击位置,驱动电机9驱动拔杆10对烟支夹持器3上的烟支21进行弹击,机械手2再由弹击位置运动到扶正位置,烟支夹持器3上的烟支21经支撑板11的凹槽进行扶正;接着,重复上述仿真模拟消费者抽吸路径及弹烟、扶正直至抽吸完成(或检测结束);之后,机械手2运动到卸料位置,夹爪气缸20驱动夹爪19夹紧机械手2携带的烟支21,机械手2向夹爪19所在方向的反方向运动,烟支21从机械手2上脱离后,夹爪气缸20驱动夹爪19松开烟支21,完成卸料。其中,机械手2由抽吸位置运动到弹击位置过程中,模拟消费者持烟在空间的挥臂摆动和翻手腕动作。
所述机械手2在预设程序中规划其仿真运动抽烟路径,携带摄像机16与补光灯17的支杆14所在的架体15固连于机械手2上,随着机械手2在空间的抽烟路径运动而运动。所述机械手1在预设程序的驱动下,补光灯17打开,摄像机16开始工作。在机械手2的实时运动情况下,摄像机16按照需求,在任意时间均可实时采集补光灯17均匀分布的区域内的有效图像,采集完成后可对相应的图像进行分析处理(注:对图像进行分析处理不属于本发明部件的工作内容),当整个装置工作结束时,机械手2返回初始位置并停止运动,补光灯17关闭,摄像机16停止采集图像。
其中扶正的具体动作为:所述烟支夹持器3夹持的烟支21在机械手2的预设程序作用下,继续运动直到V型槽结构的槽口处。此时停留的位置是根据烟支21在前期没有被弹击且位于烟支夹持器3的中心位置时与V型槽相对位置决定的空间坐标位置,被弹击的烟支21在机械手2控制的烟支夹持器3和V型槽的共同作用下,完成扶正操作。所述机械手2携带被烟支夹持器3夹持的烟支21,从扶正位置回到弹基位置,扶正动作结束。
给料具体动作为:所述机械手2携带固连的烟支夹持器3,从初始位置运动到准备开始取烟进料的位置,即与所述料斗28配合的导向器31的正下方。然后,所述机械手2控制烟支夹持器3运动到烟支夹持器3的轴心与导向器31的轴心重合的位置。在所述两轴心线始终处于同一条直线的情况下,控制机械手2,向上运动,使得所述烟支夹持器3与导向器31空间位置重合,重合过程中,导向器31出口进入烟支夹持器3内部的密封圈,使烟支夹持器3与导向器31形 成负距离,保证待测烟支从导向器31的出口进入烟支夹持器3中,被烟支夹持器的密封圈紧固包围,如图2所示;所述料斗驱动电机29驱动料斗28做旋转运动,从料斗28的待测烟支中获取单支烟(通过只容纳一支烟的料斗的通槽获得单支烟);获取的烟支21在重力作用下下落至所述烟支转向机构30,烟支21在烟支转向机构30的斜坡上通过重力作用向下滑动,从而实现完成烟支21由水平方向到竖直方向的转换,烟支21通过导向器31进入所述烟支夹持器3,烟支夹持器3夹紧烟支9后,所述机械手2垂直向下运动;直到烟支夹持器3夹持的烟支完全脱离导向器31,最终完成烟支上料。
环境气流检测具体为:在所述机械手2上夹持端的连接座23连接气流测量传感器24,机械手2携带气流测量传感器24运动到需要测量的位置。通过调节预设定程序中所述气流调节电机25的转速,利用气流测量传感器24测量气流大小,满足气流大小在150mm/s~250mm/s之间,记录气流调节电机25的转速R。以此气流调节电机25转速R为校准值,进行测量。即利用气流调节电机25已知的电机转速对应的气流大小作为校准值,然后在此电机转速下,气流测量传感器24测量的气流值对标校准值进行校准,实际气流测量传感器24测量的气流值若非此范围内的气流大小,则需要重新校准。环境气流检测过程中,所述机械手2携带气流测量传感器24运动到测试位置。设置气流调节电机25的转速为校准值R,可以保证气流大小满足在150mm/s~250mm/s之间。
