为使本发明的目的、技术方案和优点更加清楚, 下面将结合附图对本发明实 施方式作进一步地详细描述。
在纺丝卷绕过程中,工作筒管夹头轴上的丝饼直径随着纺丝时间的增加不断 增大,压丝辊和工作筒管夹头轴之间的距离也不断加大, 为了保持压丝辊的位置 在一允许的范围内且压丝辊以一定的压力和工作筒管夹头轴上正在形成的丝饼 相接触,本发明提出一种可以保证卷绕机的控制系统控制转盘随着丝饼直径的增 大逐步转动的控制方法。
为此, 首先需要进算出丝饼的直径。
本发明中, 卷绕丝饼的体积, 可按下列公式计算:
U = 1/1000 ( (Di/2) 2- (D/2) 2) π H ( 1 ) 式中: U——丝饼体积 (cm3);
Di—纺丝过程中任意时刻的丝饼直径 (mm);
D——纸筒管外径 (mm);
H——丝饼宽度 (mm)。
对应不同的纺丝品种, 丝饼的密度是可以测出的, 丝饼的重量, 可按下列公 式计算:
W = U P (2) 式中: W——丝饼重量 (g);
——丝饼密度 (g/cm3)。
同时, 根据化学纤维长丝纤度的定义, 卷绕丝饼丝的重量, 可按下列公式计 算:
W = V Ti A/10000 (3) 式中: V 纺丝速度 (m/min);
Ti——纺丝过程中的任意时刻 (min);
A——丝束纤度 (dtex)。
根据式 (2) 和式 (3 ) 任意时刻的丝饼直径, 可按下列公式计算:
Di = ( (4VA/10 II H ) Ti + D2) 1/2 (4) 也就是说, 在纺丝参数确定后, 丝饼直径 Di是时间 Ti 的函数, 利用公式 (4) 可以计算得出任意时刻的丝饼直径 Di。 其中, 纺丝速度 、 丝束纤度八、 丝饼宽度11、 丝饼密度 P和纸筒管外径 D, 是已知的纺丝参数, 可以预先设定。
在已经计算出丝饼直径 Di的基础上, 可以根据几何关系进行精确的计算, 即可以得出任意时刻筒管夹头轴圆心和转盘圆心的连线与转盘垂直于地面的垂 直直径之间所形成的角度, 即筒管夹头轴角度 a i。 筒管夹头轴角度 a i 随着纺 丝卷绕的进行不断加大。 度 a i可按下列公式计算:
Figure imgf000007_0001
式中: a i—任意时刻筒管夹头轴圆心和转盘圆心的连线与转盘垂直于地 面的垂直直径之间所形成的角度 (° ) ;
A——压丝辊圆心到转盘圆心的距离 (mm);
B——筒管夹头轴圆心到转盘圆心的距离 (mm);
Di—纺丝过程中任意时刻的丝饼直径 (mm);
d——压丝辊直径 (mm) ;
β —一压丝辊圆心和转盘圆心的连线与转盘垂直于地面的垂直直径之间的 角度 (° )。 随着纺丝卷绕的进行, 丝饼 Di的直径不断在增大, 当丝饼直径 Di 每次的增量达到预先设定的转盘启动增量值时, 即启动转盘旋转装置, 转盘转过 一定的角度 Δ a。 转盘每一步转动的角度增量 Δ a按下列公式计算转盘转动:
Δ ct = a i― a i-i 以下结合附图对本发明的卷绕机转盘传动装置的控制方法进行具体描述。 图 1为实现本发明的卷绕机转盘传动装置的控制方法的卷绕机结构示意图。 在卷绕机的机架内安装有一个可转动的转盘 5, 在该转盘的前端面安装有两个可 转动的筒管夹头轴 6.1和 6.2,每根筒管夹头轴上装有至少一个纸筒管 7.1和 7.2。 在工作的筒管夹头 6.1的上方设置一个压丝辊 4, 压丝辊的上方设置有横动装置 3, 丝束 1通过导丝钩 2、横动装置 3和压丝辊 4绕在工作筒管夹头轴 6.1的至少 一个纸管 7.1上形成丝饼。 压丝辊 4通过转轴可转动的安装在支臂 10的前端; 支臂 10通过绕轴 9安装在支架 8上, 并可以绕轴 9进行小幅度摆动 ( < Γ )。 在卷绕过程中, 压丝辊 4需要以一定的压力和工作筒管夹头轴 6.1上正在形成的 丝饼相接触。 在纺丝开始前, 筒管夹头轴直接与压丝辊 4相接触。 为方便说明, 将纺丝开始前筒管夹头轴圆心至转盘圆 5心连线与转盘 5垂直于地面的垂直直径 之间形成的筒管夹头轴角度位置为 0度,即筒管夹头轴圆心至转盘圆 5心连线与 转盘 5垂直于地面的垂直直径相重合。压丝辊 4圆心和转盘 5圆心的连线与转盘 5垂直于地面的垂直直径之间的角度为 β。
图 2显示了卷绕机在工作过程中某时刻 Ti的工作状态。 在纺丝过程中, 随 着纺丝时间的增加, 筒管夹头轴 6.1转动,卷绕在纸管 7.1上的丝饼 20的直径不 断增大, 压丝辊 4和工作筒管夹头轴 6.1之间的距离也不断加大。 为了保持压丝 辊 4的位置在一允许的范围内,同时保证压丝辊 4以一定的压力和工作筒管夹头 轴 6.1上的丝饼相接触, 转盘 5随着丝饼 20直径的增大沿顺时针方向转动。
图 3表示了卷绕机转盘传动装置的原理结构,转盘 5的前端面可以转动地安 装有筒管夹头轴 6.1和 6.2, 筒管夹头轴的驱动电机 13.1、 13.2安装在转盘 5的 后端面。 图中所示筒管夹头轴 6.1是工作筒管夹头轴, 轴上卷绕着正在形成的丝 饼 20, 压丝辊 4以一定的压力与丝饼 20相接触。 转盘 5的驱动装置包括带有减 速箱的电机 14和传动装置 12。 传动装置 12可以采用齿轮传动也可以采用齿形 带传动。 转盘驱动电机 14可以采用步进电机, 也可以采用伺服电机。 当丝饼直 径增大到预定数值 Di时, 既丝饼直径 Di每次的增量达到预先设定的转盘启动增 量值时,转盘转过相应的角度增量 Δ α。控制系统根据公式计算出该工作筒管夹 头轴在转动圆周上的相应角度位置 以及该次应转动的角度增量 Δ α, 本发明 的卷绕机转盘传动装置即启动转盘旋转装置转盘驱动电机,输入与要转动的角度 增量 Δ α相对应的脉冲, 转盘转过角度增量 Δ α。
如图 4所示,在任意纺丝时刻 Ti,工作筒管夹头轴中心即丝饼中心应处的位 置角度为 。 在丝饼中心、 压丝辊中心和转盘中心连接形成的三角形 ABC中, 压丝辊中心和转盘中心的连线长度 A、 丝饼中心和转盘中心的连线长度 B均为 已知数, 只有压丝辊中心和丝饼中心的连线长度 C随着丝饼直径的增加而变化, C= (Di+d) 12, 式中 Di为纺丝过程中任意时刻的丝饼直径, d为压丝辊直径。 根据余弦定理: C2=A2+B2-2ABcos(a+P), 可以得出任意时刻的筒管夹头轴圆心 与转盘圆 的垂直直径之间的位置角度:
Figure imgf000009_0001
进而计算出转盘的转动 Δ a :
Aa = ai - 在图 5给出了一个具体的实施例。首先确定已知的各种纺丝参数, 包括纺丝 速度 V、 丝束纤度 、 丝饼宽度11、 丝饼密度 P和纸筒管外径 D。 然后开始进行 纺丝运动。
在该实施例中, 纸管外径是 126mm, 设定的转盘启动增量值为 2mm, 即丝 饼直径每增加 2mm后, 转盘转动一个相应的 Δ a角度。
开始卷绕时, 既在 To时刻, 工作筒管夹头轴 6.1 的位置位于转盘的垂直中 心线上, a Q=0° , 丝饼直径的增加会使压丝辊 4微微上抬, 控制系统根据下列 公式 (4) 计算丝饼的直径 D1:
Dl = ( (4VA/10HH ) T1 + D2) 1/2
当丝饼直径增加 2mm时, 既当丝饼直径 D1增加到 128mm, 控制系统根据 下列公式 (5):
a 1 = arccos ( (A2+B2— (Dl+d) 74) /2AB) - β
计算得到此刻丝饼应处的筒管夹头轴角度位置 A, 此时, 角度增量 Δα
= a 0, 控制系统启动转盘顺时针转转过 Δα后, 转盘停止转动。 因为压丝辊 4 始终接压在丝饼上, 此刻随转盘的转动回到了原位。 继续纺丝, 丝饼直径的增 加会使压丝辊 4再次微微上抬,
在继续纺丝过程中, 控制系统根据下列公式 (4) 计算丝饼的直径 D2:
D2= ( (4VA/10II H ) T2 + D2) 1/2
当丝饼直径又增加 2mm时, 既丝饼直径 D2增加到 130mm时,,控制系统再 次根据公式 (5) 计算得到此刻丝饼应处的筒管夹头轴角度位置《2: α 2 = arccos ( (A2+B2— (D2+d) 74) /2AB) - β
此时, Α α = α2 - α1 ,控制系统启动转盘顺时针转转过 Δ α后转盘停止转动。 此时压丝辊 4又随着转盘的转动回到了原位。如此循环, 直到达到预先设定的纺 丝时间 Tmax, 丝饼满卷, 转盘快速转动, 将满卷的丝饼转到下面的落筒位置, 将原来空闲的筒管夹头轴 6.2转到工作位置, 移丝机构将丝束 1 从筒管夹头轴 6.1上的丝饼 20上切换到现在的工作筒管夹头轴 6.2的多个纸管 7.2上, 开始一 个新的卷绕过程。
以上所述仅为本发明的较佳实施例, 并不用以限制本发明, 凡在本发明的精 神和原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护 范围之内。
