摘　　要：针对组培苗继代培养过程中培养瓶需要人工输入输出、占用大量劳力的问题,采用运动方向相反的2条输送带与设置在其上的导流板、导流块、分流块相配合的结构方案,设计出一种培养瓶的自动排序装置。导流输送带速度v1、分流输送带速度v2、导流板倾角α和导流块楔角β是影响排序速度和运行可靠度的主要因素,当v1=0.25 m/s、v2=0.4 m/s、α=47°、β=35°时,排序装置具有较高的排序速度和良好的运行可靠度。试验结果表明:该装置能实现组培生产中常用的不同大小、形状的培养瓶的自动排序作业,瓶体运行可靠度大于94%;对瓶底直径相同、形状不同的培养瓶,各种瓶体的排序速度基本相等,但对重心低、质量小的瓶体排序效果更好;对形状相同、大小不同的培养瓶,大瓶体比小瓶体具有更好的运行可靠性。Focusing on the problem of requiring a large number of labors for transporting culture bottles during the micropropagation period of tissue culture plantlets, a kind of automatic device for lining up culture bottles was designed. The automatic device transported bottles by using two conveyer belts which had opposite motion directions, and guided, assembled and separated bottles by using guiding board, guiding block and separating block respectively. The main factors which influenced sequencing speed and reliability were guiding belt speed vI , separating belt speed v2 , dip angle ot of guiding board and wedge angle fl of guiding block. The sequencing speed and reliability were satisfactory with v1 = 0.25 m/s, v2 = 0.4 m/s, a = 47~ and fl = 35~. Experiment results showed that the device could sequence automatically different size and shape bottles which were used frequently in plant tissue culture production and the sequencing reliability was more than 94%. The sequencing speed was nearly equal and the reliability was different while lining up bottles with same diameter and different shapes, because the bottles with less mass and lower center of gravity were easier to be lined up. Bigger bottles were easier to be sequenced than smaller ones while lining up bottles with same shape and different diameters.
