【摘要】：目前陕递行业快件派送主要为人工派送,由于收件人不能及时收取快件,导致投递效率低,快递公司成本上升、用户投诉多等问题。虽然市面上已有类似存取功能的快递柜,其优点是代替了代收点的作用,实现了自动存取。但无寄件功能,且存在空间利用率低,快件存储量少,智能化程度不高,针对以上问题,提出了一种计数识别式寄存取快递库。该快递库主要包含机械系统、皮带运输机、PLC控制系统、电动剪叉机构及螺旋滑槽结构。通过交流电机带动每一层的四个皮带运输机运转,从而带动快递运转,电动剪叉机构可实现快件推出功能,PLC控制系统包括PLC、工控机、交流电机控制器以及光电传感器等。PLC通过交流电机与电动剪叉机构协调动作,实现对应快件经螺旋滑槽机构准确可靠到达取件口。该快递库工作安全可靠、空间利用率高、节能高效、方便实用,在快递行业中具有较高的推广应用价值。论文研究的重点是:从发现市面已有固定式快递柜不足出发,开展一种计数识别式寄存取快递库的结构与编程设计,利用有关软件对其关键部件进行设计,验证结构的合理性与可靠性,完成快递库系统的设计。具体内容如下:首先,论文从计数识别式寄存取快递库的整体结构入手,利用Solidworks建立了其整机模型,并详细对皮带运输装置、剪叉式推出装置及滑槽装置的功能等进行了介绍;其次,利用组态王模拟软件对控制系统进行编程;然后,进行系统原理图的绘制及相关元件的选型设计工作,最后,到工厂进行加工及调试。
[Abstract]:At present, the delivery of courier in Shaanxi delivery industry is mainly manual delivery. Due to the recipients can not receive express in time, the delivery efficiency is low, the cost of express delivery company is rising, and many problems such as user complaints and so on. Although there are courier cabinets with similar access functions on the market, it has the advantage of replacing the collection point and realizing automatic access. However, there is no sending function, and the space utilization ratio is low, the storage capacity of express mail is less, and the intelligence degree is not high. In view of the above problems, a kind of counting identification storage and retrieval express delivery library is put forward. The delivery store mainly includes mechanical system, belt conveyor, PLC control system, electric shear fork mechanism and spiral chute structure. The four belt conveyors of each layer are driven by alternating current motor to drive express delivery operation. The electric shear fork mechanism can realize the function of launching express parts. The PLC control system includes the PLC, industrial control computer. The AC motor controller and photoelectric sensor, etc. Through the coordination of AC motor and electric shear fork mechanism, PLC realizes the accurate and reliable arrival of the corresponding express through the spiral chute mechanism to the pick-up port. It is safe and reliable in work, high in space utilization rate, energy saving and high efficiency, convenient and practical, and has high value of popularization and application in express delivery industry. The key points of this paper are as follows: starting from finding the shortage of fixed express delivery cabinets in the market, developing the structure and programming design of a kind of counting and identifying storage and collecting express delivery storehouse, and designing its key parts by using relevant software. Verify the rationality and reliability of the structure, complete the design of the delivery warehouse system. The specific contents are as follows: firstly, this paper starts with the whole structure of the express store of counting and identification, establishes its whole machine model by using Solidworks, and introduces in detail the functions of belt transportation device, shear fork ejector device and chute device. Secondly, the control system is programmed by using Kingview simulation software. Then, the schematic drawing of the system and the selection and design of related components are carried out. Finally, processing and debugging are carried out in the factory.
