摘 要:目前国内三四线城市的快递分拣主要为人工分拣,受员工疲劳等因素影响,效率低、差错率高。虽然市场上已有交叉带分拣机等设备,但存在成本高、占地面积大等局限,为了改善这种情况,提出一种翻盘式快递自动分拣装置。该装置由机械系统和PLC-组态-视觉联合控制系统构成。机械系统采用皮带输送机提供循环动力,翻盘式结构通过相对运动实现双侧分拣,设计气动回路为分拣机构提供动力;PLC-组态-视觉联合控制系统采用视觉识别技术提取快递面单信息,设计了人机交互的组态王上位机通讯,获取视觉识别出的代表位置信息的字符,将PLC作为下位机控制硬件动作。结果表明,该装置工作安全可靠、空间利用率高、节能高效,适用于中小物流企业。

Abstract:At present, the delivery sorting in Chinas third-tier and fourth-tier cities is mainly manual sorting, which is affected by fatigue and other factors, resulting in low efficiency and high error rate. Although there are some equipment such as cross belt sorting machine in the market, it has the limitation of high cost and large floor space. To improve the situation, a Flip-disk typed automatic sorting device for express delivery was proposed, which was composed of mechanical system and PLC-configuration-vision joint control system. The mechanical system adopts the belt conveyor to provide the circulating power, the tilting plate structure realizes the bilateral sorting through the relative movement, and the pneumatic circuit is designed to provide the power for the sorting mechanism. The PLC-configuration-vision joint control system adopts the visual recognition technology to extract the surface information of express delivery, designs the human-computer interactive Kingview upper computer communication, and obtains the characters representing the position information identified by the vision, with PLC used as the lower computer to control the hardware action. The results show that the device works safely and reliablywith high space utilization rate and energy saving efficiency, suitable for small and medium-sized logistics enterprises.

近年來,随着互联网的发展,快递行业也得到蓬勃发展。然而,在快递物流派送的最后“100m”中,快递分拣是一道即繁琐又必不可少的工序,在我国三四线城市里的快递分拣中心,多年来一直采用人工分拣的形式,依靠人眼识别快递信息,再将其取出进行分拣,不仅效率低,而且由于员工疲劳、注意力无法长时间集中等原因,分拣差错率高,大大延长了分拣周期,带来经济损失的同时,客户体验也较差,因此市场对安全高效的自动分拣装置的需求十分迫切[1]。……
