Description

积放链输送系统 技术领域
本发明涉及积放链输送系统。
背景技术
积放链输送系统是自动化程度较高的综合性空间储运系统，其能够通过运载小车携带工件在运行线路上的任何位置根据需要随时自动停止，即运载小车可以按照需要随时进行“积存”和“释放”，其在大型涂装自动流水线上被广泛使用。
为了缩短积放链输送系统的占地空间，运载小车携带工件在输送过程中常常需要转弯和掉头，而所携带的工件长度越大，转弯半径越大。而在输送超长工件时，过大的转弯半径会大大增加设备尺寸和场地占用面积，因此现有的积放链输送系统中，通常采用横向积放方式进行转弯和掉头，以往通常采用的横向积放方式都是双承载轨&双牵引轨方式，如公开号为CN106516612A的中国专利中公开的用于大长工件输送的重载积放链输送系统，该输送系统在实际运行过程中，偶尔会因两侧牵引链运行不同步而产生卡滞现象，影响生产的顺利进行；而这种卡滞影响在积放大尺寸(如长度超过8米)工件时尤为明显。
因此，市场上亟需推出在有限场地面积上实现满足大尺寸甚至超大尺寸工件积放的积放链输送系统。
发明内容
为了解决上述技术问题，本发明申请的目的是提供一种能够适应于在大型涂装流水线中平稳运载超长工件且结构紧凑的积放链输送系统。
为了实现上述的目的，本发明提供以下技术方案：一种积放链输送系统，该系统包括：

牵引装置，由牵引链条和驱动所述牵引链条移动的驱动机构构成，所述的牵引链条同时贯穿各个所述的纵向牵引轨、各个所述的过渡牵引轨以及各个所述的横向牵引轨；以及
多个运载小车组，每个所述的运载小车组可支撑在所述的承载轨道上并且被构造为在所述牵引装置的牵引下携带一个所述的超长工件沿输送方向运动，各个所述的运载小车组由硬性连接在一起的三辆运载小车构成，相邻两辆所述运载小车的距离等于相邻两条所述横向承载轨之间的距离；其中，各个所述的运载小车组在相应所述的纵向承载轨道段上运行时，所述的三个运载小车沿着输送方向依次排列并且同时支撑在所述的纵向承载轨上，所述的三个运载小车中只有位于中部的所述运载小车耦接于所述的牵引链条；而各个所述的运载小车组在所述的横向承载轨道段上运行时，所述的三辆运载小车并排排列并且分别支撑在一条所述的横向承载轨上，所述的三个运载小车中只有位于中部的所述运载小车耦接于所述的牵引链条上。
进一步优选，所述的道岔装置包括设置在所述纵向承载轨上并且被配置成用于检测所述运载小车是否经过的检测装置以及与所述的检测装置相信号连接的控制装置，所述的第一执行机构和所述的第二执行机构均与所述的控制装置相信号连接，所述的第一执行机构和所述的第二执行机构的动作与否被设置成受控于所述检测装置反馈给所述控制装置的检测结果。
进一步优选，所述的检测装置包括一个传感器；当所述的传感器在设定时间内两次检测到所述运载小车经过时，所述的第一执行机构和所述的第二执行机构在所述控制装置的驱动下分别推动所述的第一道岔轨和所述的第二道岔轨动作，以便所述的纵向承载轨与最内侧的一个所述横向承载轨和位于中间的所述横向承载轨相连接。更进一步优选，所述的传感器为光电传感器。
进一步优选，所述的控制装置包括PLC处理器。
上述技术方案中，优选地，同一个所述运载小车中的三辆运载小车通过一刚性杆件硬性连接在一起。
相较于现有技术，本发明所提供的积放链输送系统，通过将纵向轨道段设计成单承载轨&单牵引轨输送方式，并将横向轨道段设计成三承载轨&单牵引轨输送方式，结合通过三运载小车同时携带一个工件以及依靠道岔装置断开与连接纵、横向轨道段的承载轨道的方式在纵向轨道段和横向轨道段之间转弯的设计方案，有效减少了转弯和掉头的半径，并且由于在横向轨道段，只有中间牵引轨，两侧承载轨内小车为无动力的随动方式，既简化并节约了牵引链，又避免了两牵引链运行不同步产生的卡滞现象；运行结果良好，验证了设计发明的先进性和可靠性，在超长工件输送时具有很高的推广价值和市场前景。

参见图1，其示出了一种示例实施方式的积放链输送系统100的俯视结构示意图，该积放链输送系统100包括由若干纵向输送段101、若干横向输送段102以及转向或掉头输送段103构成的输送轨道、能够沿着输送轨道运动的多个运载小车组(图中未示出)以及驱动多个运载小车组沿着输送轨道移动的牵引装置3。输送轨道包括承载轨道和牵引轨道。牵引装置3包括牵引链条31和驱动牵引链条31移动的驱动机构32。运载小车组被配置成能够携带工件，并在牵引装置3的牵引下沿着输送轨道的各段运行。
参见图2，其示出了多个运载小车组4在积放链输送系统100中A点到B点这一段输送线路10时的示意图。以下将以该段输送线路10为例，详细阐述本例中的积放链输送系统中相邻纵向输送段、横向输送段以及转向或掉头输送段的布置结构。
对于输送线路10而言，输送轨道包括两个纵向输送段101、一个横向输送段102以及分别位于一个纵向输送段101和一段横向输送段102之间的两个转向或掉头输送段103。输送线路10中的承载轨道包括两段纵向承载轨道段、一段横向承载轨道段和用于在输送方向上建立或断开纵向承载轨道段和横向承载轨道段的连接关系的一套道岔装置13。本例中，各个纵向承载轨道段由一根沿纵向延伸的纵向承载轨111构成，并且纵向承载轨111构造为是具有运行末端1110的轨道。各个横向承载轨道段由三条并行且沿横向延伸的第一横向承载轨121、第二横向承载轨122和第三横向承载轨123构成。第一横向承载轨121和第二横向承载轨122之间的距离为L1、第二横向承载轨122和第三横向承载轨123之间的距离为L2。本例中，L1和L2相等。
多个运载小车组4可支撑在承载轨道上并且被构造为在牵引装置3的牵引下携带一个超长工件500沿输送方向运动。本例中，同一个运载小车组4由通过刚性杆件40硬性连接在一起的①号运载小车41、②号运载小车42和③号运载小车43构成。其中，①号运载小车41和②号运载小车42之间的距离D1、②号运载小车42和③号运载小车43之间的距离D2将与下述提及的距离L1和距离L2相等。例如，以运送长度为12m的工件500为例， 可以将这些距离D1、D2、L1以及L2均设置为3m左右。
输送线路10中的道岔装置13具有通过第一执行机构131推动的第一道岔轨132、通过第二执行机构133推动的第二道岔轨134和始终保持连接纵向承载轨111的运行末端1110与位于最外侧的第三横向承载轨123的第三道岔轨136。第一道岔轨132被配置成在第一执行机构131的推动下建立或断开纵向承载轨111和最内侧的第一横向承载轨121的连接，第二道岔轨134被配置成在第二执行机构133的推动下建立或断开纵向承载轨111和位于中间的第二横向承载轨122的连接。第三道岔轨136为固定轨道，其始终连接在纵向承载轨111的运行末端1110与第三横向承载轨123之间。
道岔装置13还包括设置在纵向承载轨111上并且被配置成用于检测各个运载小车是否经过的检测装置以及与检测装置相信号连接的控制装置。检测装置包括一个传感器135，本例中，传感器135采用为光电传感器。控制装置包括PLC处理器138。第一执行机构131和第二执行机构133均与PLC处理器138相信号连接，第一执行机构131和第二执行机构133的动作与否被设置成受控于检测装置反馈给控制装置的检测结果；例如：当传感器135两次检测到有运载小车经过时，即①号运载小车41和②号运载小车42经过，则PLC处理器138给第一执行机构131和第二执行机构133发信号，使其分别推动第一道岔轨132和第二道岔轨134移动，以实现连接纵向承载轨111和第一横向承载轨121以及连接纵向承载轨111和第二横向承载轨122。
输送线路10中的牵引轨道将位于相应承载轨道的上侧。本例中，牵引轨道为单一轨道且包括纵向牵引轨道段、纵向牵引轨道段以及过渡牵引轨道段。牵引链条31为单根并将从牵引轨道中穿过。
如图4、5所示，纵向牵引轨道段由位于纵向承载轨111正上方的纵向牵引轨21构成道段，纵向牵引轨21与纵向承载轨111制成为一体构件。纵向牵引轨道段由过渡牵引轨(图中未示出)构成，该过渡牵引轨在第二道岔轨134建立纵向承载轨111和位于中间的第二横向承载轨122的连接时，恰好位于第二道岔轨134的正上方；本例中，第二道岔轨134与过渡牵引轨为分体设置。如图8所示，横向牵引轨道段由位于第二横向承载轨122正上方的横向牵引轨22构成，横向牵引轨22与第二横向承载轨122制成为一体构件。本例中，纵向牵引轨21、过渡牵引轨以及横向牵引22串接成一体式轨道，牵引链条31从纵向牵引轨21、过渡牵引轨以及横向牵引22穿过，各组运载小车组4中的②号运载小车42将始终挂载在牵引链条31上实现受其牵引移动。
这样，当纵向承载轨111和第一横向承载轨121通过第一道岔轨132连接以及纵向承 载轨111和第二横向承载轨122通过第二道岔轨134连接后，加上固定连接纵向承载轨111的运行末端1110与第三横向承载轨123之间的第三道岔轨136作用，③号运载小车43、②号运载小车42和①号运载小车41将可以同时运动到第一道岔轨132、第二道岔轨134以及第三道岔轨136上，而后再分别运动到第一横向承载轨121、第二横向承载轨122和第三横向承载轨123上，以实现转向之目的。
如图3示出的一个纵向输送段101的示例；该例中，两个由①号运载小车41、②号运载小车42和③号运载小车43构成的运载小车组4同时悬吊于纵向输送段101的下侧并且能够沿着纵向输送段101移动。其中，每一个运载小车组4中的三辆运载小车同时协同搬运一个工件500。
如图4-6所示，其示出了一个运载小车组4悬吊于一截纵向输送段101时的示意图。输送轨道除了纵向承载轨111和纵向牵引轨21外，在上侧还设置有梁5，纵向承载轨111和纵向牵引轨21固定在梁5上。①号运载小车41、②号运载小车42和③号运载小车43各设置复数个行走轮411、421和431，①号运载小车41、②号运载小车42和③号运载小车43沿纵向排列并且同时通过各自的行走轮支撑在纵向承载轨111，以实现沿着纵向承载轨111移动。②号运载小车42还同时通过升降抓422耦接于牵引链条31上的推手320(见图5)，②号运载小车42能够在牵引链条31的带动下沿着纵向承载轨111移动，②号运载小车42作为动力小车同时将拖着前后两侧的①号运载小车41和③号运载小车43同时沿着纵向承载轨111一起前行。
如图7所示，其示出了三个运载小车组4(共9辆运载小车)悬吊于横向输送段102的示意图。三个运载小车组4沿着输送方向依次沿着横向排列在横向输送段102上，并且可各自在横向输送段102运行。
如图8所示，每一组运载小车组4中的①号运载小车41、②号运载小车42和③号运载小车43沿横向排列，①号运载小车41支撑在第三横向承载轨123上，②号运载小车42支撑在第二横向承载轨122上，③号运载小车43支撑在第一横向承载轨121上。其中只有位于中间的第二横向承载轨122上侧的横向牵引轨22内贯穿由牵引链条31，三个运载小车中，只有位于中部的②号运载小车42的升降抓422与牵引链条31上的推手320耦接，其实现能够直接被牵引链条31牵引向前。
如图9示意出位于图7中的第三横向承载轨123上的各辆运载小车的工作情况，其中分属于三个运载小车组4的三辆①号运载小车41沿横向排列并同时支撑在第三横向承载轨123上，其可以在各自对应运载小车组4中的②号运载小车42带动下，一起向前。
本案的积放链输送系统100占地面积小，工件能够在输送过程中采用横向积放方式灵活进行转弯和掉头。在横向输送段中，采用三承载轨&单牵引轨输送方式，只有中间牵引轨，两侧承载轨内小车为无动力的随动方式，既简化并节约了牵引链，又避免了两牵引链运行不同步产生的卡滞现象，非常适合输送超大尺寸工件。
本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，本发明要求保护范围由所附的权利要求书、说明书及其等效物界定。
