本申请是以中国申请号为201711455335.2，申请日为2017年12月28日的申请为基础，并主张其优先权，该中国申请的公开内容在此作为整体引入本申请中。
技术领域
本公开涉及物品存储技术领域，尤其涉及一种物品存储设备、码垛系统及物品存储方法。
背景技术
目前，在仓储领域，通常利用自动混合码垛技术代替人工码垛，以提高运输效率，有效降低仓储运营成本。若想实现自动混合码垛，要求在码垛机器人的前端完成物品的缓存和排序。
相关技术中可实现缓存和排序功能的设备不多，对流量有较高要求的一些场景会使用多层穿梭车立体库或Miniload(一种适用于重量小的货物的箱式自动化立体库)实现这一功能，但这样的方案成本高，设备复杂。对流量要求不高的场景，一般把输送线设计成矩阵缓存系统，但这样的系统排序功能不好实现，而且效率低，占地面积较大。
需要说明的是，公开于本发明背景技术部分的信息仅仅旨在增加对本发明的总体背景的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域技术人员所公知的现有技术。

具体实施方式
下面将结合本公开实施例中的附图，对实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本公开的一部分实施例，而不是全部的实施例。基于本公开的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开的描述中，需要理解的是，术语“中心”、“横向”、“纵向”、“前”、“后”、“左”、“右”、“上”、“下”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开保护范围的限制。
如图1所示，在本公开提供的物品存储设备的一个示意性实施例中，物品存储设备包括第一输送线10、第二输送线20和缓存通道30，第一输送线10和第二输送线20绕缓存通道30螺旋上升形成双螺旋结构，缓存通道30的两端分别与第一输送线10和第二输送线20相通，第一输送线10将物品40输送至缓存通道30，缓存通道30 从第一输送线10接收物品40并将物品40输送至第二输送线20，第二输送线20从缓存通道30接收物品40并输出。
在上述示意性实施例中，第一输送线10和第二输送线20绕缓存通道30螺旋上升并形成双螺旋结构，通过第一输送线10可以将物品40输送至缓存通道30中进行存储，缓存通道30接收物品40后还可以将其输送至第二输送线20，以通过第二输送线20将物品40输出，在该过程中物品存储设备起到了缓存作用，相对于相关技术中的立体库来说，物品存储设备采用双螺旋结构可以增大物品存储量，在存储量相同的前提下可以大大减小占地面积，降低设备投入成本。
可选地，第一输送线10与缓存通道30相通的输送部的上表面与缓存通道30的入口的上表面大致平齐，这样设置可以使物品40在从第一输送线10运动到缓存通道30上时更加平稳；和/或，第二输送线20与缓存通道30相通的输送部的上表面与缓存通道30的出口的上表面大致平齐，这样设置可以使物品40在从缓存通道30运动到第二输送线20上时更加平稳。
可选地，缓存通道30的上表面水平设置。这样设置在可以使物品40能够更加稳定地存储在缓存通道30上。
如图2和图3所示，第一输送线10包括第一输送装置11，第一输送装置11用于驱动物品40沿第一输送线10的延伸方向移动，并用于驱动物品40从第一输送装置11移动到缓存通道30。也就是说，第一输送装置11的输送方向能够发生改变，既可以驱动物品40沿第一输送线10的延伸方向移动，也可以驱动物品40从第一输送装置11移动到缓存通道30。
如图1所示，第一输送线10的延伸方向为自左向右并螺旋上升，而缓存通道30垂直于第一输送线10的延伸方向，在驱动物品40从第一输送装置11移动到缓存通道30时，物品40的移动方向改变了90°。
如图5所示，可选地，第一输送装置11包括多个摆轮111，摆轮111启动后旋转用于带动物品40沿第一输送线10的延伸方向移动，摆轮111的布置方向能够发生旋转，以改变摆轮111的驱动方向，从而使物品40从第一输送线10运动到缓存通道30。
第一输送装置11上的多个摆轮111均匀布置，摆轮111可以通过驱动装置进行驱动，摆轮111既可以自转，以驱动物品40移动，也可以公转，即绕某条线旋转，比如在将物品存储设备安装在地面上时，摆轮111可以绕竖直轴线旋转，以改变摆轮111的轴线方向，即改变摆轮111的布置方向，从而改变驱动方向，使物品40能够从 第一输送线10运动到缓存通道30。
进一步地，第一输送线10还包括第二输送装置12，第二输送装置12用于驱动物品40沿第一输送线10的延伸方向移动，第二输送装置12与第一输送装置11交替布置。如图5所示，两个相邻的第一输送装置11之间设有第二输送装置12，两个相邻的第二输送装置12之间设有第一输送装置11。
第二输送装置12只需要能够驱动物品40沿第一输送线10的延伸方向移动即可，不需要改变驱动方向，这样可以降低对第二输送装置12的要求，有利于降低设备投入成本。
可选地，第二输送装置12包括第一输送带。该第一输送带用于驱动物品40沿第一输送线10的延伸方向移动。
相比于相关技术中采用穿梭车运送物品的技术方案来说，本公开实施例中的第一输送线10采用包括摆轮111的第一输送装置11和包括第一输送带的第二输送装置12，可以降低物品存储设备的成本，并且有利于提高输送效率。
如图4所示，缓存通道30包括存储工位31和输送通道32，存储工位31用于从输送通道32接收物品40以及将存储的物品40输送至输送通道32，输送通道32用于从第一输送线10接收物品40、向存储工位31输送物品40、从存储工位31接收物品40以及将物品40输送至第二输送线20。通过设置存储工位31和输送通道32，在物品40输出时，可以使物品40按照需要的顺序移出，而不需要按照物品40的存储顺序依次移出，提高了物品存储设备的适用性，也有利于提高物品输出效率。
可选地，第一输送线10上的第一输送装置11与缓存通道30的输送通道32相通，第一输送线10上的第二输送装置12与存储工位31相通。这样可以在物品40到达第一输送装置11时通过第一输送装置11上摆轮111的换向实现移动方向的改变，从而使物品40从第一输送装置11移动到输送通道32上，而存储工位31与第一输送线10可以不直接连通，因此第二输送装置12可以不具备转向功能。
具体地，输送通道32上设有第二输送带，第二输送带用于带动物品40移动至与存储工位31上的预设存储位对应的位置。通过设置第二输送带，可以将物品40输送到预设的存储位上，以便通过第二输送带将从第一输送线10接收的物品40输送至对应的存储位，或者将物品40从预设存储位输送到第二输送线20上。
进一步地，第二输送带上设有第一驱动轮组，第一驱动轮组启动后旋转，在第二输送带和第一驱动轮组的共同驱动作用下使物品从第一输送线10运动到输送通道32、 从输送通道32运动到存储工位31、从存储工位31运动到输送通道32、再从输送通道32运动到第二输送线20。通过设置第一驱动轮组，可以辅助第二输送带，并配合第一输送线10上的第一输送装置11，使物品40顺利地移位。
如图5所示，第二输送带上设有多个第一驱动轮组，每个第一驱动轮组包括沿第一方向布置的第一驱动轮321和沿第二方向布置的第二驱动轮322。可选地，第一驱动轮321包括多个，且成列布置；第二驱动轮322也包括多个，且成列布置。多个第一驱动轮321组成的驱动轮列与多个第二驱动轮322组成的驱动轮列交替布置，即两个相邻的第一驱动轮321组成的驱动轮列之间设有一第二驱动轮322组成的驱动轮列，两个相邻的第二驱动轮322组成的驱动轮列之间设有一第一驱动轮321组成的驱动轮列。
可选地，第一驱动轮321和第二驱动轮322能够正转和反转，以实现使物品40从第一输送线10运动到输送通道32、从输送通道32运动到存储工位31、从存储工位31运动到输送通道32、再从输送通道32运动到第二输送线20的目的。
可选地，存储工位31上设有第三驱动轮311，第三驱动轮311启动后旋转用于驱动物品40从输送通道32运动到存储工位31以及从存储工位31运动到输送通道32。
第三驱动轮311包括多个，多个第三驱动轮311在存储工位31上均匀布置。通过设置第三驱动轮311，可以配合第二输送带和第一驱动轮组，使物品40平稳且顺利地从输送通道32运动到存储工位31或者从存储工位31运动到输送通道32。
如图1～3所示，物品存储设备包括至少两层缓存通道30。比如包括四层。
可选地，物品存储设备包括设置在同一层的多个缓存通道30。这样可以增大存储量。
可选地，位于同一层的多个缓存通道30平行设置。这样布置可以尽可能地使物品存储设备的结构布置更加紧凑，有利于减小占地面积。
可选地，第二输送线20包括第三输送带。第二输送线20可以采用与第一输送线10相同的设置，包括具有摆轮的输送装置和输送带且交替布置；也可以采用与第一输送线10不同的设置，比如仅设置第三输送带。
可选地，双螺旋结构包绕的空间呈长圆形。这样形状既可以使第一输送线10和第二输送线20方便实现螺旋结构，又可以尽可能地实现第一输送线10和第二输送线20之间所形成的空间的充分利用，增大存储面积，减小物品存储设备的整体占地面积。
可选地，物品存储设备还包括条形码扫描装置，条形码扫描装置用于扫描物品40 上的条形码以获取物品40的物品信息。获取物品信息后，可以按照物品信息将物品40输送到对应的存储位，实现对物品40的分类；还可以按照物品信息有选择地使物品40按照预设的顺序排列或移出，实现对物品40的排序功能。
可选地，物品存储设备还包括控制器，物品40的移动可以通过控制器进行控制。物品存储设备还可以包括位置检测器，以检测物品40所处的位置，控制器根据位置检测器所检测的物品40所处的位置对物品40的运动进行控制。
基于上述的物品存储设备，本公开还提出一种码垛系统，该码垛系统包括物品存储设备，物品存储设备采用上述的物品存储设备对物品40进行缓存。
基于上述的物品存储设备，本公开还提出一种物品存储方法，该方法包括：
通过第一输送线10将物品40输送至缓存通道30；
通过缓存通道30从第一输送线10接收物品40，以对物品40进行缓存；
通过缓存通道30将物品40输送至第二输送线20；
通过第二输送线20从缓存通道30接收物品40并输出。
可选地，通过第一输送线10将物品40输送至缓存通道30的具体操作包括：
获取物品40的物品信息；
根据物品信息将物品40输送至对应的缓存通道30上。
进一步地，通过缓存通道30从第一输送线10接收物品40，以对物品40进行缓存；通过缓存通道30将物品40输送至第二输送线20的具体操作包括：
缓存通道30包括存储工位31和输送通道32，通过输送通道32从第一输送线10接收物品40，并将所接收的物品40输送至存储工位31，通过存储工位31对物品40进行缓存；
将位于存储工位31的物品40按照根据物品信息所确定的顺序移出并通过输送通道32输送至第二输送线20。
可选地，获取物品40的信息的具体操作包括：
扫描物品40上的条形码，读取条形码对应的物品信息。
上述各个实施例中物品存储设备所具有的积极技术效果同样适用于码垛系统及物品存储方法，这里不再赘述。
下面结合附图1～5对本公开物品存储设备、码垛系统及物品存储方法的一个实施例的工作过程进行说明：
如图1～3所示，物品40从第一输送线10的入口进入物品存储设备，经扫描后获 取物品信息，根据物品信息将物品40输送到对应的缓存通道30，物品40通过缓存通道30的输送通道32进入存储工位31进行缓存，当需要码垛时，物品40从存储工位31回到输送通道32，并通过输送通道32输送到第二输送线20，通过第二输送线20输出。
具体来说，当物品40到达对应的缓存通道30时，如图4和图5所示，运载物品40的第一输送线10上的第一输送装置11包括摆轮111，摆轮111的布置方向旋转后，以图示方向为参考方向，摆轮111由左右布置改为上下布置。由于物品40仍具有向左运动的惯性，缓存通道30的输送通道32上设有第二输送带，第二输送带上设有第一驱动轮321和第二驱动轮322，输送通道32上的第二输送带一直上下运动，因此在物品40从第一输送线10上运动至输送通道32时，运动至第二输送带接收端的第一驱动轮321启动并旋转，通过第一驱动轮321与摆轮111和第二输送带的配合，使物品40的运动方向发生90°变化，物品40由向左运动变为向下运动。当物品40完全进入输送通道32后，第一驱动轮321停止旋转，由第二输送带将物品40输送到存储工位31的由控制器设定的存储位上进行暂存。
当物品40到达与存储位对应的位置时，存储工位31上的第三驱动轮311启动旋转，第一驱动轮321启动且反向旋转，通过第二输送带、第一驱动轮321和第三驱动轮311的共同作用，物品40的运动方向由向下变为向左运动，进入预设存储位进行暂存。当物品40完全进入存储工位31后，第一驱动轮321和第三驱动轮311停止旋转。
当物品40需要输出时，存储工位31上的第三驱动轮311和第二驱动轮322启动旋转，通过第二输送带、第二驱动轮322和第三驱动轮311的共同作用，物品40向右运动进入输送通道32。当物品40完全进入输送通道32后，第二驱动轮322和第三驱动轮311停止旋转，物品40在第二输送带的带动下运动。
当物品40通过第二输送带运动到第二输送线20上时，由于物品40具有向下运动的惯性，因此运动到第二输送带输出端的第二驱动轮322启动并反向旋转，通过第二驱动轮322与第二输送带的配合，使物品40的运动方向发生90°变化，物品40由向下运动变为向右运动，然后由第二输送线20的第三输送带带动输出。
通过对本公开物品存储设备、码垛系统及物品存储方法的多个实施例的说明，可以看到本公开物品存储设备、码垛系统及物品存储方法实施例至少具有以下一种或多种优点：
1、采用双螺旋结构，可以大大减小物品存储设备的占地面积；
2、第一输送线采用包括摆轮的第一输送装置和包括第一输送带的第二输送装置，降低物品存储设备的成本，并且有利于提高输送效率；
3、缓存通道包括多个，可以将不同物品分别存储在不同的缓存通道上，实现对物品的分类功能；
4、缓存通道设有输送通道和存储工位，可以使物品按照需要的顺序输出，实现排序功能。
最后应当说明的是：以上实施例仅用以说明本公开的技术方案而非对其限制；尽管参照较佳实施例对本公开进行了详细的说明，所属领域的普通技术人员应当理解：依然可以对本公开的具体实施方式进行修改或者对部分技术特征进行等同替换；而不脱离本公开技术方案的精神，其均应涵盖在本公开请求保护的技术方案范围当中。
