Description

一种用于仓储的机器人及其工作方法 技术领域
本发明涉及机器人技术领域,尤其涉及一种用于仓储的机器人及其工作方法。
背景技术
智能仓储是物流过程的一个环节,智能仓储的应用,保证了货品仓库管理各个环节数据输入的速度和准确性,确保企业及时准确地掌握库存的真实数据,合理保持和控制企业库存。通过科学的编码,还可方便地对库存货品的批次、保质期等进行管理。
目前,智能仓储是在仓库内设置多个放置货品的货架,机器人根据无线指令的订单将货品所在货架从仓库搬运至员工处理区,工作人员在员工处理区挑拣、扫描商品。但是,这种机器人只能搬运整个货架,对自身的承重等性能要求较高,成本较高,货架的重量、高度等也受到限制,工作人员在货架上找寻订单货品,效率较低。
技术问题
在此处键入技术问题描述段落。
技术解决方案
本发明为了解决上述技术问题,提供了一种用于仓储的机器人及其工作方法,其无需搬运整个货架,成本较低,货架尺寸不受限制,提高工作人员拣选货品的效率,且其工作占用空间小,可以使仓库内货架密度大大提高。
为了解决上述问题,本发明采用以下技术方案予以实现:
本发明的一种用于仓储的机器人,包括移动底盘,所述移动底盘上设有架体,所述架体包括对称设置在移动底盘左右两侧的支架,所述支架上从上至下并排设有若干个可左右移动的托盘,两个支架之间的距离小于两个托盘的长度之和,所述支架上还设有可驱动各个托盘单独左右移动的第一驱动机构,两个支架之间设有用于抓取物品的机械臂,所述架体上设有可带动机械臂竖直升降的升降机构,所述移动底盘底部设有第一摄像头,所述移动底盘上还设有控制器和无线通信模块,所述控制器分别与移动底盘、第一驱动机构、机械臂、升降机构、第一摄像头和无线通信模块电连接。
在本方案中,第一摄像头用于识别仓储区域地面上的导向线或导航二维码,帮助机器人定位,配合移动底盘,实现在仓储区域自由移动。机器人通过无线通信模块接收管理中心发送的无线指令。
机器人通过升降机构带动机械臂升降,机械臂用于将托盘上的货品取下放到仓储区域的货架上,或者将仓储区域的货架上的货品取下放到托盘上。
托盘用于存放货品。两个支架之间的距离小于两个托盘的长度之和,每个支架上的托盘位于初始位置时,左侧支架上托盘的右端位于两个支架之间的中线位置,右侧支架上托盘的左端位于两个支架之间的中线位置。第一驱动机构用于驱动支架上的各个托盘单独左右移动,从而控制各个托盘移到支架内侧或移到支架外侧。
当机械臂需要将某个托盘上的货品取下时,该托盘正上方的所有托盘以及与该托盘位于同一高度的托盘都移动到支架外侧,然后将该托盘移动到机械臂正下方,机械臂将该托盘上货品取下,然后所有托盘都回到原位。同理,当机械臂需要将货品放置到某个托盘上时,该托盘上方的所有托盘以及与该托盘位于同一高度的托盘都移动到支架外侧,然后将该托盘移动到机械臂正下方,等机械臂放完货品后,所有托板都回到原位。
当机械臂需要从仓储区域的货架上较低位置取货品或要将货品放到仓储区域的货架上较低位置时,将相应的托盘移动到支架外侧,使得机械臂取货或放货不会受到托盘的阻碍。
升降机构、机械臂以及所有托盘都位于移动底盘的上方空间,托盘位于机械臂下方,大大减小了机器人在移动过程中占用的空间,使得仓储区域可以更密集的存放更多的货架,大大提高了仓储区域的空间利用率。机器人通过对各个托盘的独立移动控制,使得机械臂在工作的时候,可以通过控制相应托盘移动不阻碍机械臂工作。机器人在减小占用空间的同时能够很好的完成仓储中取货/放货操作,无需搬运整个货架,成本较低,货架尺寸不受限制,提高工作人员拣选货品的效率,且使仓库内货架密度大大提高。

本发明的最佳实施方式
在此处键入本发明的最佳实施方式描述段落。
本发明的实施方式
下面通过实施例,并结合附图,对本发明的技术方案作进一步具体的说明。
本实施例的一种用于仓储的机器人,如图1、图2、图3、图4所示,包括移动底盘1,移动底盘1上设有架体2,架体2包括对称设置在移动底盘1左右两侧的支架,支架上从上至下并排设有若干个可左右移动的托盘3,两个支架之间的距离小于或等于托盘3的长度,支架上还设有可驱动各个托盘3单独左右移动的第一驱动机构4,两个支架之间设有用于抓取物品的机械臂5,架体2上设有可带动机械臂5竖直升降的升降机构6,移动底盘1底部设有第一摄像头7,移动底盘1上还设有控制器8和无线通信模块9,控制器8分别与移动底盘1、第一驱动机构4、机械臂5、升降机构6、第一摄像头7和无线通信模块9电连接。
仓储区域的货架上放置有统一规格的周转箱31,周转箱31内放置有同一种货品。周转箱便于机械臂抓取。
在本方案中,第一摄像头用于识别仓储区域地面上的导向线或导航二维码,帮助机器人定位,配合移动底盘,实现在仓储区域自由移动。机器人通过无线通信模块接收管理中心发送的无线指令。
机器人通过升降机构带动机械臂升降,机械臂用于将托盘上的周转箱取下放到仓储区域的货架上,或者将仓储区域的货架上的周转箱取下放到托盘上。
托盘用于存放周转箱。两个支架之间的距离小于或等于托盘的长度,每个支架上的托盘位于初始位置时,左侧支架上托盘的右端位于两个支架之间的中线位置,右侧支架上托盘的左端位于两个支架之间的中线位置。第一驱动机构用于驱动支架上的各个托盘单独左右移动,从而控制各个托盘移到支架内侧或移到支架外侧。
如图12所示,当机械臂需要将某个托盘上的周转箱取下时,该托盘正上方的所有托盘以及与该托盘位于同一高度的托盘都移动到支架外侧,然后将该托盘移动到机械臂正下方,机械臂将该托盘上周转箱取下,然后所有托盘都回到原位。同理,当机械臂需要将货品放置到某个托盘上时,该托盘上方的所有托盘以及与该托盘位于同一高度的托盘都移动到支架外侧,然后将该托盘移动到机械臂正下方,等机械臂放完周转箱后,所有托板都回到原位。
当机械臂需要从仓储区域的货架上较低位置取周转箱或要将周转箱放到仓储区域的货架上较低位置时,将相应的托盘移动到支架外侧,使得机械臂取货或放货不会受到托盘的阻碍。
升降机构、机械臂以及所有托盘都位于移动底盘的上方空间,托盘位于机械臂下方,大大减小了机器人在移动过程中占用的空间,使得仓储区域可以更密集的存放更多的货架,大大提高了仓储区域的空间利用率。机器人通过对各个托盘的独立移动控制,使得机械臂在工作的时候,可以通过控制相应托盘移动不阻碍机械臂工作。机器人在减小占用空间的同时能够很好的完成仓储中取货/放货操作,无需搬运整个货架,成本较低,货架尺寸不受限制,提高工作人员拣选货品的效率,且使仓库内货架密度大大提高。
如图1、图5、图7所示,支架包括对称设置在移动底盘1前后两侧的支柱,支柱包括左右并排设置的两个立柱10,每个托盘3下方对应设有支撑梁11,支撑梁11两端分别与两个支柱的内侧的立柱10连接,支撑梁11上设有两个左右走向的滑槽12,托盘3底面对应位置设有与滑槽12匹配的滑条13,滑条13穿过对应的滑槽12。托盘3呈方形,托盘3可沿滑槽12左右移动,托盘3能够移动到支架内侧,也可移动到支架外侧。
如图5、图6、图7所示,第一驱动机构4包括设置在每个支柱内的驱动轴14,驱动轴14位于所在支柱的两个立柱10之间,驱动轴14上套设有若干个电磁离合器15,电磁离合器15与托盘3一一对应,电磁离合器15的轴套上套设有驱动齿轮16,托盘3底面前后两侧设有沿左右走向的齿条17,电磁离合器15位于对应托盘3的外侧,电磁离合器15上的驱动齿轮16与托盘3底面对应一侧的齿条17啮合,电磁离合器15通过连接件与支柱固定连接,第一驱动机构4还包括用于驱动各个驱动轴14转动的驱动模块,控制器8分别与电磁离合器15、驱动模块电连接。
电磁离合器通电接合时,电磁离合器轴套上的驱动齿轮受穿过该电磁离合器的驱动轴驱动,驱动轴转动则通过驱动齿轮、齿条传动带动托盘移动,驱动轴不转动,则通过驱动齿轮、齿条使得托盘不会受外力作用随意滑动。电磁离合器断电分离时,电磁离合器轴套上的驱动齿轮不受驱动轴的影响。通过控制各个电磁离合器的通断电能够控制选定的托盘受驱动轴驱动,从而实现控制各个托盘移动的目的。

如果货架上用于存放该周转箱的储货位高度不低于该周转箱所在托盘的高度,则在移动过程中控制该托盘上方的所有托盘以及与该托盘同样高度的托盘都移动到支架外侧,控制该托盘移动到机械臂正下方,当机器人移动到对应货架处后,机器人的机械臂将放有需上货货品的周转箱从托盘上取下放入对应储货位,完成上货操作;
如果货架上用于存放该周转箱的储货位高度低于该周转箱所在托盘的高度,则在移动过程中控制该周转箱所在托盘上方的所有托盘以及与该周转箱所在托盘同样高度的托盘都移动到支架外侧,控制该周转箱所在托盘移动到机械臂正下方,当机器人移动到对应货架处后,机器人的机械臂将放有需上货货品的周转箱从托盘上取下,接着控制高度在用于存放该周转箱的储货位高度之上的托盘都移动到支架外侧,机器人的机械臂将放有需上货货品的周转箱放入对应储货位,完成上货操作。
机器人在移动过程中控制左侧某个托盘向支架外侧移动的方法包括以下步骤:
控制第一驱动电机顺时针转动、第二驱动电机不转动;
控制左前侧的驱动轴上该待移动托盘的对应的电磁离合器通电接合,控制左前侧的驱动轴上其他电磁离合器断电分离;控制左后侧的驱动轴上该待移动托盘的对应的电磁离合器断电分离,控制左后侧的驱动轴上其他电磁离合器通电接合;控制右前侧的驱动轴上所有电磁离合器断电分离;控制右后侧的驱动轴上所有电磁离合器通电接合;
机器人在移动过程中控制左侧某个托盘向支架内侧移动的方法包括以下步骤:
控制第一驱动电机逆时针转动、第二驱动电机不转动;
控制左前侧的驱动轴上该待移动托盘的对应的电磁离合器通电接合,控制左前侧的驱动轴上其他电磁离合器断电分离;控制左后侧的驱动轴上该待移动托盘的对应的电磁离合器断电分离,控制左后侧的驱动轴上其他电磁离合器通电接合;控制右前侧的驱动轴上所有电磁离合器断电分离;控制右后侧的驱动轴上所有电磁离合器通电接合;
机器人在移动过程中控制右侧某个托盘向支架外侧移动的方法包括以下步骤:
控制第一驱动电机顺时针转动、第二驱动电机不转动;
控制右前侧的驱动轴上该待移动托盘的对应的电磁离合器通电接合,控制右前侧的驱动轴上其他电磁离合器断电分离;控制右后侧的驱动轴上该待移动托盘的对应的电磁离合器断电分离,控制右后侧的驱动轴上其他电磁离合器通电接合;控制左前侧的驱动轴上所有电磁离合器断电分离;控制左后侧的驱动轴上所有电磁离合器通电接合;

在本方案中,取货或上货时,机器人在移动过程中预先调整托盘的位置,从而减少了仓储机器人在货架前的动作,从而减少了取货、上货的时间,提高了仓储效率。在移动过程中,对于受驱动移动的托盘之外的托盘,需要通过一个电磁离合器结合通电与一个固定不转动的驱动轴连接,从而使得这些托盘不会在仓储机器人移动时自由滑动。
机器人在不动时,则不需要对受驱动移动的托盘之外的托盘进行固定,机器人可根据需要控制第一驱动电机、第二驱动电机转动,配合相应电磁离合器通断电,从而可同时控制两侧的任意托盘移动。如:第一驱动电机顺时针转动,第二驱动电机逆时针转动,左前侧的驱动轴上所有电磁离合器通电接合,左后侧的驱动轴上所有电磁离合器断电分离,右前侧的驱动轴上所有电磁离合器断电分离,右后侧的驱动轴上所有电磁离合器通电接合,则两侧的托盘都向支架外侧移动。
