The method effectively controls the reverse lap of the combing machine separation roller, the forward rotation separation, the stop rotation waiting, overcomes the disadvantages that the carding process is difficult to adjust and the traditional complicated mechanical transmission mode has low operating efficiency, and improves the transmission efficiency. Background technique
精梳机是棉纺企业生产髙附加值纺织品的必备设备。 目前, 国际上精 梳机仍以传统的机械传动方式工作。 瑞士立达公司、 意大利马佐里公司、 日本丰田公司等厂家为主要生产企业。 其中, 瑞士立达公司生产的精梳机 由于受机械传动方式的制约, 用了 10 多年时间才将工作速度由 300钳次 I分钟提高到 420— 450钳次 I分钟。 The combing machine is an essential equipment for cotton spinning enterprises to produce value-added textiles. At present, the international combing machine still works in the traditional mechanical transmission mode. Manufacturers such as Swiss Rieter, Italy Mazzar, and Toyota are the main manufacturers. Among them, the combing machine produced by Swiss Rieter Company has been used for more than 10 years to increase the working speed from 300 clamps to 1 minute to 420-450 clamps for 1 minute due to the limitation of mechanical transmission.
近年来, 国内外一些厂家开始研究, 试图将伺服技术运用到精梳机设 计上, 但迄今尚没有相关的成功报导。 In recent years, some domestic and foreign manufacturers have begun to study and attempt to apply servo technology to the design of combing machines, but so far there has been no relevant successful reports.
机械传动方式下, 其分离罗拉的运动方式是进多退少的不对称往复运 动, 是将一个对称的往复运动和一个恒速运动通过差速轮系合成完成的。 往复运动采用了共扼凸轮或者多连杆机构。如己公开的专利 CN00104907. 0 精梳机分离罗拉的传动装置, CN02100217. 7 精梳机和 CN02215287. 3 一种精梳分离运动机构。 这些方法都存在如下问题: (1 ) 共轭凸轮, 多连 杆机构, 差速轮系都是复杂的传动机构, 摩擦发热量大, 润滑困难, 传动 效率低。 (2 )共轭凸轮, 多连杆机构, 差速轮系加工难度高, 装配难度大, 费工费料。 (3 ) 共轭凸轮, 多连杆机构, 差速轮系的结构参数不便调节, 一台精梳机由其结构参数决定的只有唯一的一个有效输出长度, 设备也不 能按照纤维本身的长度分布特征调节分离长度、 搭接长度和有效输出长 度, 由此导致设备在使用时的梳棉工艺参数不易调节, 设备的适应性差, 对纤维长的可以梳理但效率低, 对纤维短的无法梳理, 导致资源浪费。 In the mechanical transmission mode, the movement mode of the detaching roller is asymmetrical reciprocating motion with more and more retreat, which is achieved by synthesizing a symmetrical reciprocating motion and a constant speed motion through the differential gear train. The reciprocating motion uses a common cam or a multi-link mechanism. Patent published as CN00104907. 0 Transmission device for combing machine separation roller, CN02100217. 7 Combing machine and CN02215287. 3 A combing separation movement mechanism. These methods all have the following problems: (1) Conjugate cams, multiple link mechanisms, and differential gear trains are complex transmission mechanisms, which have large friction heat generation, difficult lubrication, and low transmission efficiency. (2) Conjugate cam, multi-link mechanism, differential gear system is difficult to process, difficult to assemble, labor-intensive. (3) Conjugate cam, multi-link mechanism, differential wheel system structure parameters are inconvenient to adjust, a comber is only one effective output length determined by its structural parameters, and the equipment cannot be distributed according to the length of the fiber itself. The characteristic adjusts the separation length, the lap length and the effective output length, thereby causing the carding process parameters of the device to be difficult to adjust during use, the adaptability of the device is poor, the fiber length can be combed but the efficiency is low, and the fiber is short and can not be combed. Lead to waste of resources.
为了克服传统机械方式的诸多缺陷, 伺服驱动是目前的研究热点, 一 般都采用伺服电机和减速装置实现。但是,伺服电机转速较高,一般在 3000 In order to overcome many shortcomings of traditional mechanical methods, servo drives are currently the research hotspots, and are generally implemented using servo motors and reduction gears. However, the servo motor speed is higher, generally at 3000

转 /分钟一 5000 转 /分钟之间, 甚至更高, 而罗拉的转速一般都在 600 转 / 分钟以下, 所以必须给伺服电机加装减速装置。 減速装置虽然实现了转速 减小和扭矩的增大使负载平稳运行, 因为负载要求往复运动, 伺服电机必 须在较高转速下正反转, 这样正反转的频次就很难提高。 随着正反转频次 的提髙, 伺服电机长期处在起动和停止的动态过渡过程, 电机的温升增高 至超出设计范围, 不得不停机。 发明内容 Confirmation The speed/minute is between 5000 rpm, even higher, and the speed of the roller is generally below 600 rpm, so the servo motor must be equipped with a speed reducer. Although the speed reduction device realizes the reduction of the rotation speed and the increase of the torque, the load runs smoothly. Because the load requires reciprocating motion, the servo motor must be reversed at a higher rotation speed, so that the frequency of the forward and reverse rotation is difficult to increase. With the improvement of the frequency of forward and reverse, the servo motor has been in the dynamic transition process of starting and stopping for a long time, and the temperature rise of the motor has increased beyond the design range and has to be stopped. Summary of the invention
