摘  要：
【目的】研究不同减震方式对水果自动计量设备装箱合格率的影响,为水果计量装箱设备的设计制造提供参考。【方法】通过设定不同装箱质量(2500,5000,10000g)、不同减震方式(无减震、减震弹簧、发泡塑料、减震弹簧+发泡塑料)以及不同延时取值时间(0,0.3,0.5,1.0s)的对比试验,研究其对装箱合格率的影响。【结果】采用"减震弹簧+发泡塑料"的减震措施,可使装箱合格率达95%以上;延时取值时间设定为0.5～1.0s,可使传感器读数达到稳定。【结论】得到了水果自动计量装箱设备的最佳减震措施,对其进行改进,及PLC的计算提醒,对极少数不符合装箱误差要求的果箱由人工添减水果,可使装箱合格率达到100%。

摘  要：
[Objective] The impact of shock absorption methods on the qualified rate of fruit automatic weighing and packing machine was studied in this experiment in order to provide a theoretical basis for the design and manufacture of the machine. [Method] Comparative tests were done using different packing loads(2 500,5 000,10 000 g),shock absorptions methods (control test,buffer spring,froth plastics,buffer spring combined with froth plastics,) and acquisition overtime(0,0.3,0.5,1.0 s)to study their effects on weighing accuracy.[Result] It is concluded that the qualified rate of fruit packing could reach up to 95% by using the combined measure of buffer spring and froth plastics.And data acquisition of the weighing sensors was able to be stabilized by optimized PLC algorithm in which the acquisition overtime of weight value was set in the range from 0.5s to 1.0s.[Conclusion] The optimum absorption method was gained after the above experiments and improved by incorporating with PLC algorithm alarm for unqualified packing boxes in order to add or reduce fruits manually.Subsequently,the qualified rates can be raised up to 100 percent by employing the so-called improvement measures.
