技术领域
本申请涉及仓储物流技术领域，具体涉及货物分拣技术，尤其涉及分拣小车。
背景技术
交叉带分拣机通常是一种能够自动实现物料分拣的物料输送机，其一般包括皮带小车和运输轨道。其中，皮带小车一般设置在交叉带分拣机的运输轨道上，皮带小车的皮带的运转方向与运输轨道的前进方向呈交叉状。当该皮带小车移动到所规定的分拣位置时，皮带小车的皮带开始转动，使得物品向运输轨道的两侧运动，完成物品分拣送出的任务。
然而，现有的交叉带分拣机有平面式和直线式。而直线式交叉带分拣机一般采用链条链轮驱动，其结构导致皮带小车只有在分拣机的上半层可以工作，影响分拣效率。
发明内容
鉴于现有技术中的上述缺陷，本申请提供了一种改进的分拣小车，来解决以上背景技术部分提到的技术问题。
为了实现上述目的，第一方面，本申请实施例提供了分拣小车。该分拣小车包括：调节滚筒和电动滚筒；皮带，皮带套设在调节滚筒 和电动滚筒上，在电动滚筒的驱动下，皮带绕调节滚筒和电动滚筒转动；上托板和下托板，上托板和下托板对向设置，且与皮带的内侧面接触，用于支撑皮带中位于调节滚筒和电动滚筒之间的部分，其中，内侧面为皮带与调节滚筒和电动滚筒接触的侧面；前板和后板，前板和后板分别位于皮带的两侧，且均与调节滚筒和电动滚筒的滚轴、上托板和下托板固定连接；次级磁体，次级磁体与轨道的直线电机初级线圈相配合，以驱动分拣小车沿轨道移动。
在一些实施例中，调节滚筒、电动滚筒、上托板和下托板在与皮带接触的表面设置有导槽。
在一些实施例中，皮带的内侧面设置有耐磨导条，耐磨导条与导槽相嵌合。
在一些实施例中，调节滚筒的滚轴与前板和后板上的孔槽通过调节螺栓连接，调节螺栓伸出的长度能够调节调节滚筒与电动滚筒之间的距离。
在一些实施例中，分拣小车还安装有无线通讯装置和无线供电装置；无线通讯装置安装在前板或后板上，用于向分拣小车提供通讯信号，其中，无线通讯装置包括通讯天线；无线供电装置安装在前板或后板上，用于向分拣小车提供电力，其中，无线供电装置包括感应线圈板或电刷。
在一些实施例中，前板和后板上还安装有快接插头，用于各分拣小车之间的通讯信号和电力的连接。
在一些实施例中，分拣小车还安装有控制部件，控制部件位于上托板和下托板之间形成的空间内，且与无线通讯装置、无线供电装置、电动滚筒和快接插头电连接，用于控制分拣小车。
在一些实施例中，前板和/或后板上还安装有铰接部件，铰接部件用于分拣小车之间的连接。
在一些实施例中，分拣小车还安装有滚轮，滚轮沿轨道转动，以使分拣小车沿轨道移动。
第二方面，本申请实施例提供了分拣装置。该分拣装置包含轨道以及第一方面中任一实现方式所描述的分拣小车；轨道中，与分拣小 车的次级磁体同侧的导轨上设置有直线电机初级线圈，次级磁体与直线电机初级线圈相配合，以驱动分拣小车沿轨道移动。
在一些实施例中，轨道上安装有无线通讯装置和无线供电装置，其中，无线通讯装置包括无线通讯电缆，无线供电装置包括无线供电电缆或滑触线；无线通讯装置和无线供电装置分别于与分拣小车上的无线通讯装置和无线供电装置相配合，分别用于向分拣小车提供通讯信号和电力。
本申请实施例提供的分拣小车，通过设置上托板和下托板，可以使分拣小车的两面中的任一面朝上时(即在轨道上进行货物分拣时)，安装在其上的皮带均能承载货物，从而提高了分拣小车的利用率，进而可以提高分拣效率。此外，通过分拣小车上安装的次级磁体与轨道上安装的直线电机初级线圈相配合，可以实现对分拣小车的非接触驱动。这样既有利于减轻分拣小车在轨道上运行的过程中所产生的噪音，又可以提高分拣小车沿轨道移动的速度，进一步提高了分拣效率。

具体实施方式
下面结合附图和实施例对本申请的原理和特征作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释相关发明， 而非对该发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与发明相关的部分。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
请参考图1，其示出了本申请提供的分拣小车的一个实施例的爆炸结构示意图。如图1所示，分拣小车可以包括前板10、皮带11、上托板12、下托板13、调节滚筒14、电动滚筒15、后板16和次级磁体17。
在本实施例中，皮带11套设在调节滚筒14和电动滚筒15上。在电动滚筒15的驱动下，皮带11可以绕调节滚筒14和电动滚筒15转动。此时，在摩擦力的作用下，调节滚筒14也跟随皮带11一起转动。上托板12和下托板13在皮带11的内侧对向设置，且与皮带11的内侧面接触。上托板12和下托板13可以用于支撑皮带11中位于调节滚筒14和电动滚筒15之间的部分，从而使皮带11的外侧可以承载货物。其中，内侧面为皮带与调节滚筒和电动滚筒接触的侧面，内侧为皮带的内侧面所形成的空间。同时，前板10和后板16可以分别位于皮带11的两侧，且均与调节滚筒14的滚轴、电动滚筒15的滚轴、上托板12和下托板13固定连接，以起到固定作用。例如可以利用螺钉将上托板12与前板10和后板16固定连接。再例如滚轴上可以设置有螺纹，进而通过螺母将电动滚筒15固定在前板10和后板16上。
此外，分拣小车上的次级磁体可以与轨道的直线电机初级线圈相配合，从而实现非接触驱动，以驱动分拣小车沿轨道循环移动。具体地，当初级线圈中通入交流电源时，初级线圈周围的空气中产生行波磁场；次级磁体在行波磁场切割下，将感应出电动势并产生电流；该电流与气隙中的磁场相作用就产生电磁推力。由于初级线圈固定在轨道上，所以电磁推力可以推动安装有次级磁体的分拣小车移动。这种驱动方式既可以提高分拣小车的移动速度，又可以降低分拣小车在轨道上移动过程中所产生的噪音。并且在这种驱动方式下，无论分拣小车处于分拣机的上半层或下半层，分拣小车都能够承载货物，从而提 高了分拣效率。作为示例，为了便于次级磁体的拆装，可以通过螺钉将次级磁体17固定在前板10和/或后板16。
可以理解的是，本申请对次级磁体的数量以及在分拣小车上的安装位置并不限制，可以根据初级线圈在轨道上的位置进行调整。具体可以参见图2，其示出了本申请实施例的分拣小车的装配结构示意图。如图2所示，次级磁体可以位于分拣小车中靠近轨道的任一侧面上。
在本实施例的一些可选地实现方式中，上托板12、下托板13、调节滚筒14和电动滚筒15在与皮带11接触的表面可以设置有导槽。如图3所示，其示出了图2所示的分拣小车的A处的局部放大剖面图。同时，皮带11的内侧面可以设置有耐磨导条110。这样耐磨导条110与导槽相嵌合，可以保证皮带在转动过程中不发生偏移。需要说明的是，图3中耐磨导条与导槽的位置和数量仅仅是示意性的。
可选地，为了便于细微调整皮带11的张紧度，前板10和后板16上可以开设孔槽，这样调节滚筒14的滚轴可以沿孔槽移动。具体参见图4，其示出了图2所示的分拣小车的B处的局部放大示意图。如图4所示，调节滚筒14的滚轴可以与前板10和后板16上的孔槽通过调节螺栓24连接。滚轴位于孔槽壁和调节螺栓24之间。此时，调节螺栓24伸出的长度能够调节调节滚筒14与电动滚筒15之间的距离，从而可以细微调整皮带11的张紧度，同时也便于皮带11的拆装。作为示例，还可以在孔槽的两端分别设置一个调节螺栓，此时滚轴位于两个调节螺栓之间。通过两个调节螺栓伸出的长度之间的配合，可以扩大调节滚筒14与电动滚筒15之间的距离的可调整范围。
从图1中可以看出，分拣小车还可以安装有无线通讯装置18和无线供电装置19。无线通讯装置18可以安装在前板10或后板16上，用于向分拣小车提供通讯信号。其中，无线通讯装置包括通讯天线。无线供电装置19可以安装在前板10或后板16上，用于向分拣小车提供电力。其中，无线供电装置包括感应线圈板或电刷。具体参见图2所示，无线通讯装置18和无线供电装置19通过螺钉安装在前板10上。分拣小车在通讯信号和电力的控制下，可以沿轨道移动并进行货物分拣。
可以理解的是，当一个分拣小车所接收的通讯信号和电力可以同时控制多个分拣小车时，各分拣小车之间可以通过快接插头20实现电连接。如图2所示，前板10和后板16上都可以安装有快接插头20，用于各分拣小车之间的通讯信号和电力的连接。并且为了降低生产成本，与该分拣小车电连接的其他分拣小车上可以不用安装无线通讯装置和无线供电装置。
此外，为了进一步提到分拣效率，分拣小车还可以安装有控制部件。如图1所示，控制部件21可以位于上托板12和下托板13之间形成的空间内，且与无线通讯装置18、无线供电装置19、电动滚筒15和快接插头20电连接，用于控制分拣小车，从而实现货物的自动化分拣。此时控制部件21内可以安装控制程序，控制部件21根据无线通讯装置18提供的通讯信号，可以控制电动滚筒15转动，从而使皮带11转动以分拣货物。控制部件21也可以通过快接插头20和电缆来控制其他分拣小车进行货物分拣。
此时，为了保证各分拣小车之间的电连接的稳定性，防止快接插头或电缆受力损坏，分拣小车上还可以安装有铰接部件22，用于分拣小车之间的机械连接。铰接部件22可以安装在前板10和/或后板16上。如图2所示，铰接部件22安装在后板16上，并且前板10上还可以设置连接孔。于是该分拣小车上的铰接部件22与其他分拣小车上的连接孔可以通过螺钉连接。这样既保证了分拣小车之间连接的稳定性，又不会对各分拣小车之间在轨道移动过程中发生的相对转动造成干涉。同时，还可以使位于安装有直线电机初级线圈的轨道上的分拣小车在驱动力的作用下，可以带动位于没有安装直线电机初级线圈的轨道上的分拣小车，实现分拣小车沿轨道的循环移动。
可以理解的是，为了减小分拣小车与轨道之间产生的摩擦力，提高分拣小车的移动速度，分拣小车上还可以安装有滚轮23。滚轮的数量和安装位置在本申请中并不限制。如图2所示，可以利用常用的方法将滚轮23分别可以安装在后板16的两侧。这样滚轮可以沿轨道转动，以使分拣小车沿轨道移动，从而保证分拣小车不会偏移出轨道。
本申请还提供了一种分拣装置。该分拣装置可以包含轨道以及上 述实施例中所描述的分拣小车。并且轨道中与分拣小车的次级磁体同侧的导轨上设置有直线电机初级线圈，次级磁体与直线电机初级线圈相配合，以驱动分拣小车沿轨道移动。该分拣装置可以为各种类型的分拣机，如平面式分拣机或直线式分拣机。作为示例，可以参见图5a和图5b，其分别示出了本申请提供的分拣装置的一个实施例的立体结构示意图和侧视图。
如图5a所示，分拣装置可以包含轨道，其中，轨道可以包含两个直线轨道50和两个曲线轨道51。两个直线轨道50通过两个曲线轨道51连接形成环形封闭轨道。分拣小车52沿轨道依次排列。此时，直线轨道50中与分拣小车52上的次级磁体同侧的导轨上可以设置有直线电机初级线圈501，具体参见图6，其示出了分拣装置的A处的局部放大示意图。通过直线电机初级线圈和次级磁体相配合，可以实现非接触驱动。这种驱动方式既可以提高分拣小车的移动速度，从而提高分拣装置的分拣效率，又可以降低分拣小车在移动过程中产生的噪音。可以理解的是，由于分拣小车52在曲线轨道51上不进行货物分拣，所以曲线轨道51上可以不设置直线电机初级线圈。
从图5a中可知，分拣装置还可以包括供货台53和滑槽54。供货台53分别设置于两个直线轨道50的一端(具体位置可以根据分拣小车的运转方向来设置)，用于向直线轨道上提供货物。滑槽54设置于直线轨道50的两侧，用于将直线轨道上的货物输送至不同的区域(即不同的滑槽可以代表不同的目的地)。
可选地，轨道上还可以安装有无线通讯装置和无线供电装置。其中，无线通讯装置可以包括无线通讯电缆。无线供电装置可以包括无线供电电缆或滑触线。无线通讯装置和无线供电装置分别于与分拣小车上的无线通讯装置和无线供电装置相配合，分别用于向分拣小车提供通讯信号和电力。如图7所示，在直线轨道50的两条相互平行的导轨之间安装有无线通讯电缆502和无线供电电缆503。此时，分拣小车上的感应线圈板和无线供电电缆503之间产生的电信号可以给分拣小车内部的电路器件供电。而分拣小车上的通讯天线可以接收无线通讯电缆502发送的通讯信号，从而控制分拣小车将货物运送至对应的 滑槽。当分拣小车移动至对应的滑槽后，分拣小车上的皮带转动，从而将皮带上的货物转移至滑槽。再由滑槽将货物传输至对应的区域。这样可以实现货物的自动分拣，从而进一步提高分拣效率。
以上描述仅为本申请的较佳实施例以及对所运用技术原理的说明。本领域技术人员应当理解，本申请中所涉及的发明范围，并不限于上述技术特征的特定组合而成的技术方案，同时也应涵盖在不脱离所述发明构思的情况下，由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本申请中公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
