Description

接力式货物拣选系统和拣选方法 技术领域
本发明总体地涉及物流仓储技术，更具体地涉及电商领域的接力式货物拣选方法、货物拣选系统、计算装置和计算机可读存储介质。
背景技术
电子商务和网络购物的迅猛发展，既给物流仓储行业带来了迅速崛起的契机，也给仓储物流行业带来前所未有的挑战。人工拣选即拣选员持拣选任务单(可为纸质、IPAD等、语音、VR介质)完成拣选作业。该方式是仓储物流拣选方式中成本最低的，其优点是仓储运营中心硬件成本低，在拣选任务增加时可以增加拣选作业人员提高系统出货能力；该方式最大的缺点是仓储系统中货位上物品的种类和数量信息与实际货位上的物品种类和数量不同步。为进一步提高分拣效率、减少从订单到交货的时间、减少劳动力负担，采用机器人自动拣选系统的货到人方式是一种有效的模式。上述货到人方式基于智能搬运机器人，机器人根据订单需要及库存信息，自动行驶至目标货架正下方并将目标货架抬起送到分拣站，分拣站配有显示屏等显示装置，该显示装置提配货订单所需货品所在货位信息，分拣人员根据提示取下所需货品放到指定容器从而完成分拣任务，在分拣任务结束后机器人将货架送回指定位置。上述货到人方案全程无需人员走动，大幅提高了分拣效率、降低人员劳动强度。
发明内容
拣选单人工拣选与机器人货到人拣选各有利弊，如何有机结合这两种拣 选方式充分发挥两种拣选方式的优势，提高整体方案的拣选效率，是亟待解决的重要问题。
鉴于上述情况，提出了本发明。
根据本发明的一个方面，提供了一种接力式货物拣选系统，包括：多个搬运机器人，搬运机器人能够将货架搬起并运输；人工拣选货架区，用于存放供人工拣选的货物；人工拣选集货辅助工具，供承载容器，并便于人工驾驶或运输，后台系统能够操作来将每个人工拣选辅助工具与承载的容器、对应的订单信息绑定；机器拣选货架区，布置有多个货架，用于存储货物并供机器人搬运，在货架区，货架排列成多行多列的货架阵列，空行/列构成供搬运机器人通行的通道；操作工位，其中搬运机器人搬运货架至操作工位，由拣货方从货架拣货或向其上货；控制系统，能够与搬运机器人、进行人工拣选的人进行通信，控制进行订单分配、货架搬运和货物拣选，其中对于既涉及人工拣选区的货物，也涉及机器拣选货架区的货物的混合型订单，在控制系统的控制下，以人到货的拣选方式和货到人拣选方式的串行拣选的接力方式完成混合订单的拣选，其中针对涉及人工拣选区的货物，通过人到货的拣选方式来完成拣选；以及针对涉及机器拣选货架区的货物，通过货到人的拣选方式来完成拣选。
根据本发明的另一方面，提供了一种利用权利要求1的接力式货物拣选系统执行的接力货物拣选方法，包括：对于既涉及人工拣选区的货物，也涉及机器拣选货架区的货物的混合型订单，在控制系统的控制下，以人到货的拣选方式和货到人拣选方式的串行拣选的接力方式完成混合订单的拣选，其中针对涉及人工拣选区的货物，通过人到货的拣选方式来完成拣选；以及针对涉及机器拣选货架区的货物，通过货到人的拣选方式来完成拣选。
利用根据本发明实施例的接力货物拣选系统和接力货物拣选方法，整体基于数据驱动，来以接力方式进行拣选(先人工拣选、后机器人货到人拣选，或者先机器人货到人拣选、后人工拣选)，有机结合了拣选单人工拣选与机器人货到人拣选的优势，提高整体方案的拣选效率。

具体实施方式
为了使本领域技术人员更好地理解本发明，下面结合附图和具体实施方式对本发明作进一步详细说明。
根据本发明的一个实施例，提供了一种接力式货物拣选系统，包括：多个搬运机器人，搬运机器人能够将货架搬起并运输；人工拣选货架区，布置有多个人工拣选货架，人工拣选货架上存储有供人工拣选的货物，每个人工拣选货架具有唯一的编号，人工拣选货架上的工位、工位上的货物标识以及数量信息被存储于控制系统中；人工拣选集货辅助工具，供承载容器，并便于人工驾驶或运输，后台系统能够操作来将每个人工拣选辅助工具与承载的容器、对应的订单信息绑定；机器拣选货架区，布置有多个货架，用于存储货物并供机器人搬运，在货架区，货架排列成多行多列的货架阵列，空行/列构成供搬运机器人通行的通道；操作工位，其中搬运机器人搬运货架至操作工位，由拣货方从货架拣货或向其上货；控制系统，配置为对订单进行分类，分为人工拣选型订单，货到人拣选型订单和混合型订单，其中人工拣选型订单仅涉及人工拣选区的货物，货到人拣选型订单仅涉及机器拣选货架区的货物，混合型订单既涉及人工拣选区的货物，也涉及机器拣选货架区的货物，其中对于混合型订单，在控制系统的控制下，以人到货的拣选方式和货到人拣选方式的串行拣选的接力方式完成混合订单的拣选，其中针对涉及人工拣选区的货物，通过人到货的拣选方式来完成拣选；以及针对涉及机器拣选货架区的货物，通过货到人的拣选方式来完成拣选。
图1示出了根据本发明一个实施例的货物拣选系统100。货物拣选系统100包括控制系统10、搬运机器人20、、操作工位50、人工拣选货架区30、机器拣选货架区40、人工拣选集货辅助工具60。
人工拣选货架区30用于存放供人工拣选的货物。在一个示例中，在人工拣选货架区30存放在销售旺季或者促销时期的热门商品，即频繁被下单的商品。如果把热门商品放于机器拣选货架区，采用货到人方式拣货，则需要频繁搬运货架到工位、拣货、把货架搬运回货架区。针对热门商品，采用人工拣选方式，不需搬运货架，一次能够针对多个订单针对多种热门商品来进行拣选，相比于货到人拣选方式，效率更高。
机器拣选货架区40布置有多个货架，用于存储货物并供机器人20搬运，在货架区，货架排列成多行多列的货架阵列，空行/列构成供搬运机器人通行的通道。
在图1所示的示例中，人工拣选货架区30布置有多个人工拣选货架，人工拣选货架上存储有供人工拣选的货物，每个人工拣选货架具有唯一的编号，人工拣选货架上的工位、工位上的货物标识以及数量信息被存储于控制系统中。
人工拣选集货辅助工具60供承载容器，并便于人工驾驶或运输。后台系统能够操作来将每个人工拣选辅助工具与承载的容器、对应的订单信息绑定，例如在进行订单分配时，将订单和容器相关联，在将容器放置于人工拣选辅助工具时，将容器与人工拣选辅助工具相关联，这样完成了人工拣选辅助工具与承载的容器、对应的订单信息之间的相关联。从而，后台操作系统能够根据这样的关联信息和人工拣选货架区上的货位和对应货物信息，来规划拣货人员的最优行走、拣货路径。下文中，容器有时也称为料箱。
人工拣选集货辅助工具60例子有集货小车、载有托盘的地牛、笼车等。图2示出了作为人工拣选集货辅助工具例子的集货小车例图。
在一个示例中，在人工拣选集货辅助工具上附着有指示如何拣选订单的人工拣选货物的拣选单指示工具，在一个示例中，拣选单指示工具可以为纸质拣选单或无纸型拣选单(如RF、IPad、手机等)。
优选地，在拣货人员例如推着人工拣选集货辅助工具在人工拣选货架区进行拣选时，随着拣选的进行，实时更新相关联的货架、货架上的工位以及工位上的货物信息，例如手动触发无纸型拣选单上的货物拣选完成信息，例如如果无纸型拣选单上指示在某货架、某工位拣选1本某书籍，则在完成后，可通过语音、或触摸等方式进行输入，以指示该拣选已完成，由此系统 进行相关货架工位上货品数量等状态的更新。
搬运机器人20在机器拣选货架区内部以及机器拣选货架区和操作工位之间以及其它地区活动，能够将货架32搬起并运输,搬运机器人20在控制系统10的控制下，执行货物搬运任务。例如，机器人20可以沿货架阵列中的空着的空间60(机器人通行通道的一部分)行驶，运动到目标货架30的下方，举起目标货架32，搬运到被分配到的操作工位50。优选地，机器人具有提升机构、摄像头和通信部件，具有自主导航功能；搬运机器人经由通信部件与操作系统通信，甚至可以与其它搬运机器人通信。搬运机器人能够根据摄像头拍摄的地面上的二维码而定位并向前行驶，能够行驶至货架下方，并利用提升机构将整个货架举起。
在一个示例中，货架32为方形架体，可分为多层，用于放置货物，被搬运机器人20运输，拣货方从其上拣货；货架底端具有四根位置对称、高度大于机器人高度的架腿，货架底部允许机器人通行；货架每一层也都有对应的标签供识别。在一个示例中，每个货架底部都具有供搬运机器人识别的二维码，每个货架的二维码都具有唯一性；每个货架尽可能多的放置多种类货物，争取实现每个货架涵盖尽可能多的订单，减少货架的搬运次数。
操作工位50是货到人拣选情况下拣选方操作的地方，搬运机器人20搬运货架32至操作工位50，由拣货方80(人工或者机器人)从货架32拣货或向货架32上货。
控制系统10配置为对订单进行分类，分为人工拣选型订单，货到人拣选型订单和混合型订单，其中人工拣选型订单仅涉及人工拣选区的货物，货到人拣选型订单仅涉及机器拣选货架区的货物，混合型订单既涉及人工拣选区的货物，也涉及机器拣选货架区的货物。其中对于混合型订单，在控制系统的控制下，以人到货的拣选方式和货到人拣选方式的串行拣选的接力方式完成混合订单的拣选，其中针对涉及人工拣选区的货物，通过人到货的拣选方式来完成拣选；以及针对涉及机器拣选货架区的货物，通过货到人的拣选方式来完成拣选。
具体地，各个订单涉及的每种货物都有各自的类别，或者放置在人工拣选货架区，或者放置在机器拣选货架区。控制系统根据每个订单涉及的所有货物的类别，来对订单进行分类，如果订单涉及的所有货物均位于人工拣选 货架区，则将该订单分类为人工拣选型订单。如果订单仅涉及机器拣选货架区的货物，则将该订单分类为货到人拣选型订单，如果订单既涉及拣选区的货物，也涉及机器拣选货架区的货物,则将该订单分类为混合型订单。
在一个示例中，控制系统并不进行显式的订单分类操作，而是对于要处理的订单，就将其与某容器和某人工拣选集货辅助工具绑定，然后不管其是何种类型订单，其对应的容器都被放置在人工拣选集货辅助工具上，然后人工拣选集货辅助工具被运输至人工拣选货架区，在人工拣选货架区，拣选人员根据打印出来的纸质订单或电子工具指示的订单来对相关的订单进行拣选，即对于涉及到人工拣选区货物的订单(容器)，进行拣选；而对于不涉及人工拣选区货物的订单(容器)，不予处理。接下来，优选地，在人工拣选集货辅助工具上所有涉及人工拣选区货物的容器(订单)被处理后，人工拣选集货辅助工具被运输至操作工位，以便对于其中的涉及机器拣选货架区货物的订单进行拣选。不过，在某些情况下，对于某人工拣选集货辅助工具，并不需要一次对其中涉及人工拣选区货物的订单都完成人工拣选，也可以是人工拣选、机器拣选、人工拣选、机器拣选交叉进行的形式。
控制系统10可以为由处理器、存储器、软件、网络等组件配置的计算平台。控制系统10可以向电子商务个人用户提供电子购物服务。控制系统10可以包括一个或多个服务器，可以为集中式控制架构或者分布式计算架构。服务器可以具有处理器和存储器，在存储器中可以具有订单池。
控制系统也会存储机器人和系统的logo信息、订单信息、操作过程的相关信息等。
控制系统10可操作来与机器人20、操作工位处的辅助显示装置、拣货方通信，通信方式例如为无线通信技术或有线通信技术。控制系统10还可操作来通过网络与外界通信。
用户可以使用客户端通过网络连接到控制系统10，用户通过电子购物应用程序APP的购物用户界面下达订单，控制系统10基于订单来确定待搬运货架、负责搬运的搬运机器人、搬到哪个操作工位、以及搬运机器人的搬运路线，并向搬运机器人传达搬运指令，以及在操作工位指令拣配方进行拣货操作等等。
操作工位50为货到人拣货方式中拣货发生的场所，搬运机器人20搬运 货架32至操作工位，由拣货方80从货架32拣货或向其上货。
一般地，操作工位50布置在货架区的周围。
优选地，在操作工位50处设置有播种墙，播种墙上的货位处放置有容器，每个容器对应于订单，对于货到人的检索方式，搬运机器人搬运货架到操作工位，拣货员拣选货架上的货物并放置到播种墙上的对应容器中，当对应订单的货物拣选完成时，让对应容器拿走送去打包，然后放上新的容器，以对新的订单进行货物拣选。图3示出了播种墙的示意图，其中播种墙上安装有显示装置，其上显示信息，以指示用于将待拣选商品信息及其在货架的位置信息等均在显示屏上显示出来，拣货人员会根据液晶屏的显示信息，在货架上拿去相应的商品；拣货人员将取到的商品用扫码枪扫描，如果扫描结果与待拣商品条码等信息一致，拣货人员根据屏幕、指示灯等提示将货品放到播种墙上的指定容器中，并继续执行下述任务，直至本次拣货任务结束；如信息不一致，则屏幕给出商品错误提示，要求拣货人员重新执行拣货任务。
优选地，人工拣选拣选货架区的货物的拣选频率大于机器拣选货架区的货物的拣选频率。
基于上述接力货物拣选系统，提出了人到货人工拣选与基于机器人的货到人拣选相结合的接力拣货拣选方法，其中基于人工的人到货拣选和基于机器人的货到人拣选，二者无次序先后要求，即，可以先进行基于人工的人到货拣选再进行基于机器人的货到人拣选，亦可以先进行基于机器人的货到人拣选再进行基于人工的人到货拣选，也可以二者穿插的形式。
基于上述系统，人到货人工拣选与基于机器人的货到人拣选相结合的接力环节，可以采用换容器模式(也称换箱模式)，也可以采用不换容器模式(不换箱模式)，即采用相同的载有容器的集货辅助工具，或者二者混合以及其他形式等。
图4示出了根据本发明实施例的先人到货拣选、后货到人拣选的接力拣选方法400的总体流程图。
如图4所示，在步骤S410中，进行人工拣选。
具体地，容器被放置在辅助集货小车上，容器与订单信息绑定，拣选人员根据操作系统规划的路径，推动辅助小车到人工拣选区域的各个指定位置，拣取相应的货物，放至对应容器中。
优选地，这里集货小车上仅放置涉及人工拣选货架区货物的订单对应的容器，而不放置仅涉及货到人货架区货物的订单对应的容器。
不过，根据需要，可以将一个阶段的待处理订单对应容器均放置在集货小车上，而不区分订单内货物的类型，即，不管订单涉及到的货物是否涉及位于人工拣选货架区的货物，对应容器都放置在集货小车上。在这种情况下，在人工拣货时，拣货员根据指示，例如纸质订单或者电子订单信息，来进行拣货。
在步骤S420中，人工拣选后的集货小车被运输至操作工位处，根据后续的操作模式，进行换箱操作或者不进行换箱操作。
换容器模式：即在人到货拣选和货到人拣选的切换期间，将集货小车上的容器卸下来，将容器放置到播种墙上，拣选人员通过扫描容器条码或者拣选单，从而使后台系统建立播种墙上的拣货工位、对应容器、对应订单信息的对应信息，从而为后面的货到人拣选做好准备。
不换容器模式：即在人到货拣选和货到人拣选的切换期间，容器依然放置在集货小车上，不被变动位置，以集货小车为播种墙进行拣货操作，即。整个接力拣货的系统在基于机器人的货到人子库区和基于人到货的人工拣选子库区采用相同的载有容器的集货辅助工具(集货小车、载有托盘的地牛、笼车等)，不进行换箱操作，以最大程度降低接力环节的工作量，提高接力拣货的接力效率。
通过扫描条码等形式可以建立混合单、集货辅助工具、集货辅助工具货位、容器和由混合单拆分得到的子订单(拆分得到的人到货拣选子订单和货到人拣选子订单)的某一或某几个的绑定对应关系，绑定对应关系建立之后，拣货人员通过扫描混合单、集货辅助工具、集货辅助工具货位、容器和子订单中任意一条码可以使后台系统获取上述集合单、集货工具、集货工具货位、容器和子订单的某一或某几个的绑定对应关系和对应信息，
接下来，在步骤S430中，进行基于机器人的货到人拣货。
具体地，基于机器人的货到人拣货可以通过下述操作进行：
在步骤S431中，确定货架。
具体地，控制系统根据业务需求、库存信息和货架选取策略确定某一或某几个目标搬运货架。
在步骤S432中，机器人搬运。
具体地，控制系统根据机器人调度策略，指定某机器人将该货架搬运至指定操作工位。
在步骤S433中，拣货。
具体地，机器人搬运至操作工位后，多个机器人将根据调度策略在操作工位进行排队；操作工位配有显示屏，待拣选商品信息及其在货架的位置信息等均在显示屏上显示出来，拣货人员会根据液晶屏的显示信息，在货架上拿去相应的商品；拣货人员将取到的商品用扫码枪扫描，如果扫描结果与待拣商品条码等信息一致，拣货人员根据屏幕、指示灯等提示将货品放到指定容器中，并继续执行下述任务，直至本次拣货任务结束；如信息不一致，则屏幕给出商品错误提示，要求拣货人员重新执行拣货任务。
这样就完成了先人到货拣选模式，后货到人拣选模式的接力拣选。
替代地，可以先货到人拣选模式，后人到货拣选模式的接力拣选
在一个示例中，基于机器人的货到人拣选系统，拣货工位的显示屏可以采用VR眼镜或者语音提示代替。
在一个示例中，在人工拣选步骤，除了可以采用上述摘果的方式外，也可以采用“摘果+播种”的组合方式，即操作工人先根据统计的待拣货品信息去人工货架区采用摘果的方式进行集货，然后将集到的货品以播种的方式放置到相应订单对应的容器中。
在一个示例中，上述货到人拣选子步骤，除了按照上述直接拣选方式外，还可以采取分层拣选的模式，具体可以参考上海极络智能科技有限公司在先提交的中国专利申请(申请号：201610825164.7；专利名称：分层货物拣选方法、系统和计算装置)。
在一个示例中，每当人工拣选货架区的货架上的货物被人工拣选时，存储于控制系统中的人工拣选货架上的工位、工位上的货物标识以及数量信息被更新。这样的更新可以由拣货员手工完成，例如在手持电子设备上输入相应信息；替代地，可以通过相应的监控功能来自动或半自动实现，例如通过视频监控、图像处理来自动实现，这个过程中，还可以结合自动语音识别技术，也可以结合人工纠错操作。
需要说明的是，在前述说明中，在人到货的拣选方式中，由人工运输承 载有携带容器的人工拣选集货辅助工具到人工拣选货架区拣货，不过替代地，也可以是自动运输工具携带容器到人工拣选货架区，由等待在那里的拣选人员进行人工拣选。具体地，在人工拣选集货辅助工具到达人工拣选货架区后，由人工例如按照控制系统指示的订单拣选顺序来进行货物拣选。
在一个示例中，为了保持系统中订单状态及时更新，以便驱动后续的任务正确执行，对于接力方式的两阶段，任一阶段的货物拣选完成后，控制系统中维持的相应订单的拣选状态被更新。
概况起来，本发明至少提供了以下技术方案：
(1)、一种接力式货物拣选系统，包括：
多个搬运机器人，搬运机器人能够将货架搬起并运输；
人工拣选货架区，用于存放供人工拣选的货物；
