摘要： 目前对于形状和尺寸均确定的刚体的自动上料已有成熟技术,但对于柔性物体的自动上料尚没有完善的解决方案,针对具有高度柔性的海带条设计了海带条自动上料机.该机采用PLC控制、步进电机驱动,包括绕水平轴间歇回转180°的转台和在转台上对称布置的2对用于夹持海带条的专用夹具.通过对海带条相对尼龙的摩擦系数、海带条在自重作用下弯曲与伸出长度关系的规律、海带条强度等实验得到了海带条的基本物理力学性能,设计并制造出对厚度范围在0.5～1.5 mm的海带条有足够夹持力且同时可以顺利被拉出的专用夹具,完成海带条自动上料机的机械系统及控制系统的设计.通过对该机的试运行,证明研制的海带条自动上料机满足了海带打结机自动上料的要求.

Abstract: At present, there is mature technology about automatic feeding of rigid body which has certain shape and dimension, but there is no perfect solution for automatic feeding of flexible body. So an automatic feeding machine of kelp strip which has high flexibility character was designed. The automatic feeding machine was controlled by PLC, and was driven by stepping motor,and a turntable that intermittently rotating 180° around the horizontal axis, and two dedicated fixtures that symmetrically layout on the turntable and used for clamping kelp strip were also included in this machine. Through experiments in consideration of friction coefficient between kelp strips and nylon, the law of relationships between curved shape of kelp strip and its length that stretched out under the role of gravity, and the strength of kelp strip,the basic physical and mechanical performance of kelp strip was obtained. The dedicated fixture which had adequate clamping force for kelp strip was designed and manufactured, the thickness is 0.5-1.5 mm, and kelp strip could be pulled out from the fixture smoothly. The mechanical system and the control system design of the automatic feeding machine of kelp strip were completed by this paper. Through commissioning for the automatic feeding machine of kelp strip, we found that, the feeding machine met the automatic feeding requirement for the kelp-knotted machine.
