Description

搬运方法、搬运装置及搬运系统
本公开要求在2018年04月18日提交中国专利局、申请号为201810352344.7的中国专利申请的优先权,该申请的全部内容通过引用结合在本公开中。
技术领域
本公开涉及智能物流技术领域,尤其涉及搬运方法、搬运装置及搬运系统。
背景技术
电子商务的快速发展,既给快递行业带来了前所未有的发展机遇,也给快递服务提出了严峻的挑战。传统的人工矩阵式分拣方式早已经无法满足快递行业高效、低成本的需求,且要面临差错率高、人工强度大、空间利用率低、管理难等问题。因此,越来越多的快递公司开始使用自动化设备。
作为一种应用,越来越多的物流机器人被用来自动搬运仓库中的货架,盛放物品的货架在仓库放置的时候需要放置到具体的坐标位置,物流机器人根据导航路径行进到货架的坐标位置(即,行进到货架的正下方)时停止行进,先识别货架,然后抬起货架,最后将货架搬运到工作站,由工作站人员从货架上拣选物品或者将物品补货到货架上。
发明内容
在实际工作情况中,货架往往并不能准确的被放置在预定的坐标位置上(例如货架被碰撞后发生一定偏移),这就导致物流机器人到达货架的坐标位置并停下来后,如果没有识别到货架,物流机器人还需要重新行进并寻找货架。物流机器人先停下来再寻找货架的过程中,会导致物流机器人搬运货架的工作时间变长,影响货架的搬运效率。
因此亟需一种全新的物品搬运方式。

具体实施方式
下面结合附图和实施例对公开进行说明。可以理解的是,此处所描述的具体实施例仅仅用于解释本公开,而非对本公开的限定。另外,为了便于描述,附图中仅示出了与本公开相关的部分而非全部结构。
图1示出,本公开实施例提供的货物拣选系统100的工作情境的示意图。
货物拣选系统100包括控制系统10、搬运装置20(例如,移动机器人)、库存容器30(例如,货架)、缓存容器40、订单容器50。
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也可以与电子商务服务系统对接,并由该电子商务服务系统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。服务器具有处理器101和存储器102,在存储器102中可以具有订单池103。
用户使用的电子装置60通过网络连接到控制系统10,或者用户使用的电子装置60通过网络连接到与控制系统对接的电子商务服务系统,电子装置60上一般安装有电子购物应用程序APP,用户通过电子购物应用程序APP的购物用户界面下达订单,订单通过网络传送到控制系统10,或者通过网络先传送到电子商务服务系统,再由该电子商务服务器系统传送到控制系统10,控制系统10可以将订单存储于订单池103中。
控制系统10可操作来与搬运装置20、拣选站S处的辅助显示装置、电子装置60、拣货人员或者其它自动化拣货设备通信,通信方式例如为无线通信技术或有线通信技术。
搬运装置20在控制系统10的控制下,执行货物搬运任务。例如,搬运装置20可以运动到目标货架30的下方,举起目标货架30,搬运到被分配到的拣选站S。在一个示例中,移动机器人具有提升机构,以及具有自主导航功能,搬运装置20能够行驶至货架下方,并利用提升机构将整个货架举起。
货物库存区G中具有多个库存容器30,如,货架,货架上放置有各种货物, 例如如同我们在超市中见到的放置有各种商品的货架一样。可以由上货人员对库存区的货架进行商品上架或者商品下架等操作。
在一个示例中,货架为方形架体,货架底端具有四根位置对称、高度大于移动机器人高度的架腿,货架底部允许移动机器人通行;以及货架排列成多行多列的货架阵列,空行/列构成移动机器人通行通道。
缓存容器40和订单容器50可以放置于各个拣选站S,缓存容器40可以缓存从货架上拣选出的物品,然后再根据订单信息将缓存容器40缓存的物品分拣到对应的订单容器50中。各个拣选站S处还可以配置有播种墙。播种墙优选为易于被移动,例如具有轮子。订单容器50可以放置在不同播种墙上。
在一个示例中,缓存容器40和订单容器50可以具有标签,有关标签可以为传统纸质标签,如条形码,也可以为电子标签,如射频标签RFID等。置物容器40和订单容器50的形态可以相同,也可以不同。
实际进行货物拣选时,控制系统10从订单池中取得一个待处理订单,将待处理订单分配到一个拣选站S;基于订单的信息,控制系统10确定目标搬运货架30,指定某移动机器人将目标货架30搬运到拣选站S,由拣选人员或其它自动化拣选设备根据来自控制系统10的提示信息将货物从目标货架30取出,放置到订单对应的订单容器40中,该订单容器40可以例如放置在播种墙上,完成了货物拣选后的订单容器可以被搬运到打包台进行打包。
需要说明的是,本公开实施例中的搬运方法、搬运装置及搬运系统不仅适用于上述货物拣选场景,也适用于货物分拣场景、搬运场景等其它需要搬运装置搬运货物的应用场景。
参阅图2,图2展示了物品搬运平台的示意图。物品搬运平台包括搬运装置1以及搬运装置的搬运的目标对象(例如,货架2),搬运装置1在物品搬运平台内将货架2可以从一个地点搬运到另一个地点。每个搬运装置1与要搬运的货架之间存在一个导航路径3,该导航路径上包括一个或多个配置为位置坐标识别的导航点4。除此之外,物品搬运平台中还存在一个或多个障碍区域5,例如该障碍区域5为货架2所在区域,搬运装置1的导航路径3可以设定为不能通 过该障碍区域5。需要说明的是,搬运装置1采用现有技术中任何一种导航方式进行导航,例如二维码视觉导航、惯性导航、SALM导航或者巡线导航等,也可以采用现有技术中任意多种导航方式的结合方式进行导航,例如二维码视觉导航结合惯性导航或者二维码视觉导航结合SLAM导航等。本公开实施例的技术方案对导航方式不做具体限定。
参见图3,搬运装置1可以包括行走机构101。通过该行走机构101,搬运装置1能够在工作空间内移动。除此之外,搬运装置1还可以包括对举升机构102,当识别并对准到货架2时,搬运装置1通过举升机构102能够抬起货架2。为了简单起见,图3仅示出了单个搬运装置1,物品搬运平台可以包括任何适当数量的搬运装置1。搬运装置1上的目标识别装置103在搬运装置1靠近货架2时,能够有效的对货架2进行识别。除此之外,搬运装置1上还包括配置为识别导航点4的导航识别组件(图3未示出)以及控制整个搬运装置1进行行进及导航的控制模块(图3未示出)。
图4为本公开实施例提供的货架2的一种示意图,货架2存储物品6。在特定实施例中,货架2包括多个隔层,每个隔层能够容纳物品6。另外,在特定实施例中,物品6也可以从货架2内或货架2上的挂钩或杆进行悬挂。物品6在货架2上能够以任何适当的方式放置在货架的内部或外表面。货架2能够被搬运装置1滚动、携带或以其他方式搬运。为了方便搬运装置1对货架2进行搬运,货架2包括一个或多个货架支撑部202以及配置为标识货架身份的货架标记点201。
物品6代表适合于在自动库存、仓库、制造和/或零件处理系统中存储分拣、或传送的任何物品,其可以是任何的材料,可以是有生命或无生命的物体。作为一个例子,物品6可以表示存储在仓库中的商品。搬运装置1可以搬运控制系统指定货架2,该货架2包含与要打包的客户订单相关联的特定物品6,以便递送给客户或其他方。
作为另一个例子,物品6可以代表存储在机场的行李设施中的行李。搬运 装置1可以取回包含要被运输、追踪的行李的货架2。这可以包括选择特定的行李物品用于爆炸物筛选,搬运与已经转换了登机口的航班相关联的行李物品,或者移除属于已经错过了航班的乘客的行李物品。
作为又一个示例,物品6可以表示制造工具包的各个组件。更具体地说,这些组件可以表示打算包含在组装产品中的组件,例如用于定制计算机系统的计算机组件。在这样的实施例中,搬运装置1可以检索由与客户订单相关的规范所标识的特定组件。
作为又一个示例,物品6可以代表人。例如,在医院环境中,货架2可以表示包含特定患者的床。因此,物品存放系统可以被配置为提供用于移动医院病床的安全有效的系统,这限制了患者受伤的可能性并且减少了由于人为错误而导致的错误的可能性。总之,物品6可以是适合于以任何适当形式的货架2存储的任何合适的物品。
在操作中,搬运装置1能够在工作空间内移动,并且当举起货架2时,能够在工作空间内搬运货架2。基于接收到的搬运命令,搬运装置1可确定搬运装置1的目的地。例如,在特定实施例中,搬运装置1可从控制系统处接收搬运装置1的目的地的信息。搬运装置1可以通过无线接口、有线连接或使用任何其它合适的部件来接收该信息,以便于与控制系统进行通信。一般地,基于控制系统的命令,可以全部或部分地控制搬运装置1至任何需要的地方。
作为一个举例,本说明书的其余部分假定搬运装置1以无线的方式接收以任何适当形式构造的命令、数据、指令或信息。这些命令用于识别特定的货架2,以使搬运装置1移动到目的地来搬运货架2。搬运装置1可以通过行走机构101上的马达或轮子来移动搬运装置1和/或货架2。
响应于接收到的命令,搬运装置1移动到由命令识别的存储位置(参见图5-图6),搬运装置1可以与识别到的货架2对接。搬运装置1可以以任何适当的方式与货架2对接,使得当搬运装置1与货架2对接时,货架2联接到搬运装置1和/或由搬运装置1支撑。例如,在特定实施例中,搬运装置1通过将其自身定位在库存支架下方而与货架2对接,提高搬运装置1的举升部1021,直 到举升机构抬起货架2离开地面。在这样的实施例中,当搬运装置1与货架2对接时,搬运装置1可以支撑货架2的全部或部分重量。另外,在特定实施例中,搬运装置1的一个或多个部件可以抓取货架2的一个或多个部件,与货架2的一个或多个部件抓握、连接、互锁或以其他方式交互,以形成搬运装置1和货架2之间的物理连接。在搬运装置1搬运货架2的过程中,可以通过旋转的方式作对货架2的姿态朝向进行调整。
在实际的应用场景中,每个货架2在存放的时候都会设置一个具体的位置坐标,而将货架2按照规定的坐标放置的过程中,通常货架2的实际放置点与其应放的位置坐标之间会存在一定的偏差,搬运装置1按照货架2的应放位置坐标去寻找货架2时,由于位置偏差,这就导致移动运转装置1需要停下来反复的寻找货架2的位置,导致时间的浪费,降低了货架的搬运效率。
参见图6,本公开实施例公开了一种搬运方法,应用于搬运装置1,包括:
步骤601,根据导航路径,以第一速度向目标对象的位置行进;
搬运装置1在起始点获得搬运任务后,可以根据搬运任务获得目标对象(例如,货架2)的位置坐标,通过获取搬运装置当前的位置坐标以及目标对象的位置坐标,搬运装置1能够获取其导航路径3,该导航路径3上面包含多个导航点4。为了尽快的接近目标对象,搬运装置1可以采用第一速度接近目标位置。第一速度可以是搬运装置1的正常运动速度,或者根据实际的需要设置的速度,通过设置第一速度,搬运装置1可以使用较少的时间接近目标位置。
步骤602,当搬运装置1的当前位置与目标对象的位置之间的距离小于或等于第一距离时,以第二速度向所述目标对象的位置行进,第二速度小于第一速度。
第一速度通常是较快的速度,当采用较快的速度去靠近目标对象的时候,通常会由于搬运装置速度过快而难以准确的识别目标对象。为此,搬运装置1可以实时获知当前位置与目标位置(例如,货架2的理论坐标值)之间距离,当该距离小于第一距离时,改变搬运装置1的速度为第二速度,第二速度为方便对目标对象进行识别的速度,可以理解的,第二速度小于第一速度。
步骤603,在以第二速度行进时,识别目标对象上的标记点,并在识别到目标对象上的标记点时,根据所述目标对象的标记点与目标对象进行对准;
当搬运装置1与目标对象的距离小于或等于第一距离时,说明搬运装置1已经靠近目标对象,此时可以开启搬运装置1上的目标识别组件103,通过该目标识别组件103来识别目标对象上的标记点。
作为一种实现方式,在以第二速度行进时,启动搬运装置上的目标识别装置103,使该目标识别
Figure PCTCN2019081298-appb-000001
103识别目标对象上的标记点。当然,作为另一种实现方式,也可以在搬运装置开始根据导航路径行进时就开启目标识别组件103。
目标识别组件103可以是多种类型的设备,例如,目标识别组件置103可以是一个摄像装置,对应的,标记点可以是一个图形标记(例如,二维码图形),目标识别组件103还可以是一个RFID信号接收器,此时标记点可以是一个RFID标签。即,目标识别组件103可以是任何能够对目标对象进行识别的装置或设备。此处不对目标识别组件103的设备类型进行限定。
步骤604,在与目标对象对准后,停止行进,并抬起所述目标对象;
步骤605,在抬起所述目标对象后,向预设位置行进。
导航路径包括多个导航点。
搬运装置1可以通过如下方式确定搬运装置1的当前位置与目标对象的位置之间的距离是否小于或等于第一距离:
其中一种方式是:判断搬运装置1是否到达导航路径上的预定导航点,若是,则确定搬运装置1的当前位置与目标对象的位置之间的距离小于或等于第一距离。
其中另一种方式是:判断搬运装置1是否到达导航路径上的预定导航点,若是,则利用搬运装置1上的自导航装置测量所述搬运装置1离开所述导航路径上的预定导航点的距离;当所述搬运装置1离开所述导航路径上的预设导航点的距离达到预设长度时,则确定所述搬运装置1的当前位置与所述目标对象的位置之间的距离小于或等于所述第一距离。
在一种可选方式中,预定导航点可以为导航路径上所有导航点中的最后一 个导航点。
当没有识别到目标对象上的标记点时,搬运装置1自动返回到指定地点。
进一步的,搬运装置1还可以将没有识别到目标对象上的标记点的事件上报给控制系统,如控制系统中的服务器。
搬运系统中存在多个搬运装置1,每个搬运装置1需要按照特定的路线运行,这样才会使整个搬运系统上的所有搬运装置1的搬运效率最高。参见图7,根据本公开实施例的一种具体实现方式,所述获取目标对象的目标位置,以第一速度接近所述目标位置,包括:
步骤701,获取所述目标对象的位置以及所述搬运装置的起始位置;
步骤702,根据所述目标对象的位置以及所述搬运装置的起始位置规划导航路径3;
步骤703,根据规划得到的导航路径,以第一速度向所述目标对象的位置行进。
在完成导航路径3之后,搬运装置1可以通过导航点4的导航识别组件105来识别搬运系统中的导航点4,根据本公开实施例的一种具体实现方式,该方法还包括:
步骤801,搬运装置1确定所述导航路径3上的所有导航点4。
作为判断搬运装置1是否靠近目标对象的一种方式,可以根据导航路径3上导航点的位置来进行,参见图8,根据本公开实施例的一种具体实现方式,所述方法还包括:
步骤802,判断所述搬运装置1是否到达所述导航路径3上所有导航点4中的最后一个导航点4。
步骤803,若是,则确定所述搬运装置1的当前位置与所述目标位置的距离小于所述第一距离。
通过判断最后一个导航点,可以快速的判断出搬运装置1是否接近目标对象。
对于导航点间距较大的情况来讲,搬运装置1到达最后一个导航点之后, 通常还需要运行一段距离才能到达目标对象,为了降低搬运装置1识别目标对象的时间,参见图9,根据本公开实施例的一种具体实现方式,在步骤S802之后,所述方法还包括:
步骤901,基于所述搬运装置1上的自导航装置,确定所述搬运装置1离开最后一个导航点4的距离。
搬运装置1上的自导航装置可以是多种类型的装置,例如陀螺仪、加速度计、GPS等。
步骤902,判断所述搬运装置1离开最后一个导航点的距离是否达到预设长度。
可以根据实际的需要设定搬运装置1与最后一个导航点的距离,基于该距离,确定将搬运装置1降低为第二速度。
步骤903,当所述搬运装置1离开最后一个导航点4的距离达到预设长度后,则确定所述搬运装置1的当前位置与所述目标位置的距离小于所述第一距离。
当所述目标识别组件103没有识别到目标对象的标记点时,搬运装置1可以通过原地绕圈或类似的方式继续寻找标记点。
当所述目标识别组件103识别到目标对象的标记点,但无法读取所述标记点的信息时,所述搬运装置1自动返回到指定地点。除此之外,所述搬运装置1还将标记点的信息无法读取的目标对象的信息上报给控制系统。
当所述目标识别
Figure PCTCN2019081298-appb-000002
103识别到标记点后,搬运装置1能够利用所述目标识别组件103读取所述标记点中的信息,基于该信息,搬运装置1能够确定所述信息与所述搬运装置1获取的任务信息是否一致,当所述信息与搬运装置1获取的任务信息一致时,则将该目标对象移动到预定位置。
作为一种情况,标记点的信息中还存储有目标对象(例如,货架)的朝向信息,搬运装置需要按照预定的朝向将目标对象放置在具体的位置。为此,搬运装置1需要基于所述信息,确定所述目标对象的朝向信息,并控制搬运装置1上的举升机构102以预设朝向将目标对象移动到预定位置。如搬运装置1上的转向机构可调整举升机构102的朝向,使举升机构102按照预设朝向将目标对 象移动到预设位置。
除了正常的情况之外,还会出现信息错误的情况,例如搬运装置1的任务信息与标记点中的信息不一致。当所述信息与所述搬运装置1获取的任务信息不一致时,所述搬运装置1将所述目标对象的信息上报给控制系统。
为了更好的通过第二运动速度来识别目标对象,作为一种可选情况,在所述搬运装置1以第一速度运动时,所述目标识别组件103具有第一朝向。由于此时目标识别组件103不需要执行识别任务,该第一朝向可以为方便目标识别组件103存放及固定的朝向。
当在所述搬运装置1以第二速度运动时,所述目标识别组件103以第一角速度运动,此时目标识别组件103大致朝向目标对象的标记点,并通过第一角速度的设置,保证了搬运装置1在第二速度运动的过程中,目标识别装置103仍能够大致朝向目标对象的标记点。
除此之外,本公开实施例提供了一种搬运装置1,包括:
行走机构101,配置为所述搬运装置1的行进;
对接头102,配置为当所述搬运装置1与所述目标对象对接时,可操作以联接至或支撑所述目标对象;
目标识别组件103,配置为对所述目标对象上的标记点201进行识别;

控制模块,配置为:
根据导航路径,控制所述行走机构101以第一速度向所述目标对象的位置行进;
当所述搬运装置1的当前位置与所述目标对象的位置之间的距离小于第一距离时,控制所述行走机构101以第二速度向所述目标对象的位置行进,并启动所述搬运装置1上的目标识别组件103,所述第二速度小于所述第一速度;
在以所述第二速度行进的过程中,控制所述目标识别组件103识别所述目标对象上的标记点;
在所述目标识别组件103识别到所述目标对象的标记点时,根据所述目标对象的标记点控制所述行走机构的行进以使所述搬运装置与所述目标对象对准;

在所述举升机构抬起所述目标对象后,控制所述行走机构向预设位置行进。
启动所述搬运装置1上的目标识别组件103,使所述目标识别组件103以第二速度识别所述目标对象上的标记点201。
当所述目标识别组件103识别到所述标记点201之后,控制所述搬运装置1的速度降为零。
搬运装置以第一速度行进时,所述目标识别组件具有第一朝向。
搬运装置以第二速度行进时,所述目标识别组件以第一角速度运动。
第三方面,本公开实施例提供了一种用于存储物品的系统,包括存储物品的目标对象以及移动所述目标对象的搬运装置1,所述搬运装置1能够:
根据导航路径,以第一速度向目标对象的位置行进;
当所述搬运装置的当前位置与所述目标对象的位置之间的距离小于或等于第一距离时,以第二速度向所述目标对象的位置行进,所述第二速度小于所述第一速度;
在以所述第二速度行进的过程中,识别所述目标对象上的标记点;
