Description
本发明属于智能化农业机械领域,涉及一种植物工厂物流***,特指一种适用于植物工厂立体栽培的多区物流机器人、平台及运作方法。
植物工厂是现代设施农业发展的高级阶段,是一种高投入、高技术、精装备的生产体系,集生物技术、工程技术和***管理于一体,使农业生产从自然生态束缚中脱离出来。按计划周年性进行植物产品生产的工厂化农业***,是农业产业化进程中吸收应用高新技术成果最具活力和潜力的领域之一,代表着未来农业的发展方向。
在植物工厂中,划分为育苗区、移栽区、栽培区、收获区和包装区等功能分区。在实际过程中,需要将栽培的植物搬运至各个分区。目前,植物工厂的整体结构设计趋于完善,但其中的自动化物流***还非常欠缺,传统的人工搬运的方式,其劳动强度大,作业效率低,且多层栽培架的高度较高,人工搬运不方便。而栽培架单层结构体整体升降物流输运的方式成本较高且难以完成多区域的物流作业,因此设计一种适用于植物工厂立体栽培的多区物流机器人平台能够大幅提升植物工厂的物流作业效率,具有重要意义。
在现有的技术中,各个行业有着不同用途的物流装置。
申请号为201810838620.0的发明专利申请,公开了一种物流用的升降装置,通过传送带将重物传送到升降箱内,使用齿轮和同步带将重物上移到升降台,随后机械臂下的机械抓抓取重物再由工作人员摆至高处货架,该装置适用于物流公司中转站搬运重物且需要人工操作,提升效率低,难以实现植物工厂自动化生产的高效作业需求。
申请号为201710145683.3的发明专利申请,公开了一种物流设备的升降装置及其工作方法,通过气囊的充气和放气实现平台盖的高度调节,该装置能时时检测货物重量,避免超过或重量不均衡引发侧翻,但无法在确定的工位停留进行运作,且不满足在植物工厂作业时各区之间搬运的需求。
申请号为201811652021.6的发明专利申请,公开了一种用于吊运物体的转向升降装置,解决了吊运过程中同步或者异步地控制吊运物体的水平转动和垂直移动的问题,该平台无法在植物工厂的各个区域中移动,不能满足植物工厂的物流要求。
综上所述,现有的物流装置由于其适用场景不同,很难满足植物工厂多层立体栽培模式下,大跨度高举升降搬运以及在不同作业域间的进行高效物流作业的需求,同时多数物流系 统仍需要人工参与,不仅作业效率较低,同时也难以满足植物工厂无菌生产的需求。为了实现植物工厂物流自动化和高效作业,本发明设计一种适用于植物工厂立体栽培的多区物流机器人平台,能够实现多层立体栽培条件下的高举升多区域物流搬运作业,最高作业高度可达2.8米,相较于现有技术,本发明不仅能够实现多区物流作业,且在高举升作业条件下,***具有较高的稳定性和定位精度,能够满足植物工厂无菌化生产条件下,物流***的无人化高效作业的生产需求。

上述实施例的实施原理为:高举升降装置3未开始工作时,一级升降机构5、二级升降机构6、三级升降机构7层层嵌套,均处于初始工位。物流装置行驶至相应工作区域,高举升降装置3开始作业。在电动推杆9的带动下,二级升降机构6从一级升降机构5伸出。当二级升降机构6上升的同时,带动同步带13运动,同步带13带动三级升降机构7上升。滚珠丝杠升降机构8底部的第一电机23开始运行,带动滚珠丝杠21转动,丝杠螺母20向上运动,丝杠螺母20上连接的第一安装板17带动左右两侧的滑块15向上运动。拉绳位移传感器通过位移变化给控制器输入电压量,控制器经过比较输出脉冲,控制电机调整位移以实现高度上的精准定位,使平移插取装置4达到栽培架48目标层数。
平移插取装置4未开始作业时,一级平移机构24、二级平移机构25和三级平移机构26堆叠组合,均处于初始工位。高举升降装置3上升动作结束后,即滚珠丝杠升降机构8达到任务高度,平移插取装置4需要完成伸出动作。首先二级平移机构25在第二电机32的驱动下,驱动第一驱动同步齿轮33带动两侧第一光面涨紧轮34同步逆时针方向转动,第一从动同步齿轮31的外侧在一级平移机构24的同步齿条29上向右移动,带动二级平移机构25向右沿着重型滑轨的外轨28平移,直到拉绳传感器检测到位移变化已达到参考值,停止运动。随后三级平移机构26的第三电机37动作,驱动第二驱动同步轮38,带动两侧第二光面涨紧轮39逆时针方向转动,通过压板与同步带固定在一起的翻转电机壳45随之在滑轨上向右运动,直到拉绳传感器检测到位移变化已达到参考值,停止运动,两只叉指41进行插取。此时,电动推杆9带动整个平移插取装置4向上移动,叉指41将插取的物品抬起脱离栽培架48。
平移插取装置4装载结束后,需要完成回位。首先三级平移机构26的第三电机37反转, 带动单面同步带顺时针转动,使得翻转电机壳45在滑轨上向左移动至初始位置。随后二级平移机构25的第二电机32反转,带动第一光面涨紧轮34顺时针转动,第一从动同步齿轮31的外侧带在一级平移机构24的同步齿条29上向左移动,带动二级平移机构25向左沿着重型滑轨的外轨28平移,直至初始位置。
装载工作结束后,高举升降装置3需要完成下降动作。首先,滚珠丝杠升降机构8上的第一电机23反转,带动滚珠丝杠21反转,从而使得丝杠螺母20向下运动,丝杠螺母20上的第一安装板17连同左右两侧的滑块15随之向下运动直到拉绳传感器检测到位移变化回零时停止运动。随后电动推杆9开始回位,带动二级升降机构6回到初始位置,同步带13拉动三级升降机构7同时完成回位。
