Description
本发明属于纺织领域,具体涉及一种纱线假捻加弹的生产方法及纱线假捻加弹过程中过尾接头的检测方法。
“纱线假捻加弹”是指将某种纱线经过假捻加弹处理后获得具有一定特征性能的丝线,包括但不限于纺织领域中比较常见的涤纶丝,例如其中涉及到的POY(预取向丝(高速纺丝))和DTY(拉伸变形丝,通常称为涤纶低弹丝),DTY正是利用涤纶预取向丝(简称POY)做原丝进而通过拉伸、假捻变形加工后制成,在此过程中,由于POY是成卷存在的,固在将其制成DTY的过程中必然存在成卷丝卷的尾部与头部,其中存在两种生产方式,一种是当一卷POY丝卷生产完之后再替换另一卷,此方式需要经常通过人工进行新丝卷的升头操作,效率低且过度依赖人工,比较容易出错或者忘记升头,且存在废丝较多;另一种方式是:为了提升生产效率等目的,生产中一般是将多个POY卷之间的头部与尾部依次相接,正是由于存在这种头部与尾部的接头,则生产的DTY丝卷中会有部分丝卷含有过尾接头(例如现有技术中常见,通常将一个15公斤的POY经过假捻加弹制成3个5公斤的DTY,而最后一个DTY通常就会存在过尾接头),为了提升DTY丝卷的等级,目前通常是采用人工对这种过尾接头信息进行记录,而后在后期将其清除,但是这种方式同样过度依赖人工的干预,易出现误记现象或漏记现象,而且效率较低,人工成本较高,同时可能出现的废丝较多,原料成本不易降低。

(1)使所述的头尾依次相接的多个纱线丝卷的纱线穿过检测通道再进行所述假捻加弹工序,其中,所述检测通道通过对走完纱线的一个纱线丝卷切换至头尾依次相接的后一个纱线丝卷的位置变换信息进行收集,收集的每一个所述位置变换信息标识一个过尾接头;
(2)当收集到一个所述位置变换信息时,将存在一个过尾接头的假捻加弹后成卷的丝卷切换掉,重新进行一个新的假捻加弹成卷;
以此类推,每收集一个所述位置变换信息时,就将存在一个过尾接头的假捻加弹后成卷的丝卷切换掉,重新进行一个新的假捻加弹成卷。
根据本发明的一些优选且具体的方面,步骤(1)中,所述的走完纱线的一个纱线丝卷从第一方向进入所述检测通道,所述的头尾依次相接的后一个纱线丝卷从第二方向进入所述检测通道,所述第一方向与第二方向不同。

根据本发明,所述纱线包括但不限于涤纶、尼龙、聚对苯二甲酸乙二醇酯等纱线。
在本发明的一些实施方式中,所述连续生产方法包括采用加弹机进行生产,所述加弹机包括原丝架,所述检测通道设置在所述原丝架的解舒中心位置。

由于上述技术方案运用,本发明与现有技术相比具有下列优点:
本发明创新地采用在纱线假捻加弹的连续生产过程中增设检测通道,通过纱线穿过检测通道的位置变换信息来确定过尾接头的出现并检测记录,进而能够确保过尾接头能够被及时记录并切换假捻加弹后成卷的丝卷而重新进行一个新的假捻加弹成卷,使得过尾接头存在于被切换掉的丝卷的最外表面,易被清除,保证丝卷的质量等级,且几乎不会浪费原料丝,极大降低了生产成本,同时通过自动检测过尾接头信息,避免了现有技术中过度依赖人工的干预而易出现的误记现象或漏记现象,提升了生产效率,降低了人工成本。
为了更清楚地说明本发明实施例的技术方案,下面将对实施例描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动性的前提下,还可以根据这些附图获得其它的附图。
图1为本发明实施例1的一个POY丝卷在穿过通孔而被第一光电开关检测到的结构示意图;
图2为图1中所示的一个POY丝卷走完丝之后切换至后一个POY丝卷的过程示意图;
图3为图2中的后一个POY丝卷在穿过通孔而被第二光电开关检测到的结构示 意图,并且重新在走完丝的POY丝卷的摆放位置增补了依次头尾相接的再一个POY丝卷;
其中,1、第一光电开关;2、通孔;3、第二光电开关。
以下结合具体实施例对上述方案做进一步说明;应理解,这些实施例是用于说明本发明的基本原理、主要特征和优点,而本发明不受以下实施例的范围限制;实施例中采用的实施条件可以根据具体要求做进一步调整,未注明的实施条件通常为常规实验中的条件。
实施例1
如图1-3所示,本例以涤纶丝中利用涤纶预取向丝(简称POY)做原丝进而通过拉伸、假捻变形加工后制成DTY(拉伸变形丝,通常称为涤纶低弹丝)为例,其连续生产方法包括:使头尾依次相接的多个纱线丝卷经过假捻加弹工序;使所述的头尾依次相接的多个纱线丝卷的纱线穿过检测通道再进行所述假捻加弹工序,其中,所述检测通道通过对走完纱线的一个纱线丝卷切换至头尾依次相接的后一个纱线丝卷的位置变换信息进行收集,收集的每一个所述位置变换信息标识一个过尾接头;
当收集到一个所述位置变换信息时,将存在一个过尾接头的假捻加弹后成卷的丝卷切换掉,重新进行一个新的假捻加弹成卷;
以此类推,每收集一个所述位置变换信息时,就将存在一个过尾接头的假捻加弹后成卷的丝卷切换掉,重新进行一个新的假捻加弹成卷。
具体地,如图1-3所示,所述的走完纱线的一个纱线丝卷从第一方向进入所述检测通道,所述的头尾依次相接的后一个纱线丝卷从第二方向进入所述检测通道,所述第一方向与第二方向不同。
同时本例中的所述检测通道包括用于供所述的头尾依次相接的多个纱线丝卷的纱线通过的通孔2以及设置在所述通孔周侧的检测器件组件,所述检测器件组件包括第一检测器件和第二检测器件,所述的走完纱线的一个纱线丝卷从第一方向进入所述通孔2并通过所述第一检测器件检测,所述的头尾依次相接的后一个纱线丝卷从第二方向进入所述通孔2并通过所述第二检测器件检测,在所述的走完纱线的一个纱线丝卷切换至所述的头尾依次相接的后一个纱线丝卷的过程中,所述第一检测器件和第二检测器件均检测不到纱线的存在。
进一步地,所述第一检测器件和第二检测器件分别为光电开关,当所述光电开关检测到纱线存在时,输出一个信号(例如可以是高电平电信号),当所述光电开关检测不到纱线存在时,输出另一个信号(例如可以是低电平电信号),所述位置变换信息即为所述的另一个信号。具体地,所述第一检测器件、第二检测器件分别位于所述通孔2的左右两侧,当输出所述的另一个信号时,纱线从第三方向进入所述通孔2,所述第三方向与所述第一方向、所述第二方向均不同。
本例中,在图1中,第一方向示意着从右向左指向通孔2的方向,第二方向示意着从左向右指向通孔2的方向;当然,如果在图3中,其实第一方向示意着从左向右指向通孔2的方向,第二方向示意着从右向左指向通孔2的方向;因此,实际上,本例中的第一方向一般代表着正在向通孔2中走丝的POY丝卷的位置信息,第二方向代表着正在向通孔2中走丝的POY丝卷的后一个POY丝卷的位置信息;
而当第一方向所代表的POY丝卷走完丝之后,由于后一个POY丝卷与前述POY丝卷为头尾相接的,因此,会形成如图2所示的中间状态,也即此时纱线进入通孔2的方向既不是第一方向也不是第二方向,而是处于第一方向与第二方向之间的第三方向;同时在图2所示状态中,由于纱线是基本是从中间进入通孔2中,其避开了第一光纤开关1和第二光电开关3,也即这两个光电开关均检测不到纱线的存在,此时,控制***会收到或生成一个代表着位置变换信息的电信号(前述的另一个信号,例如可以是低电平电信号),也即过尾接头出现的信号,在此信号提示下,后续工序就会将存在一个过尾接头的假捻加弹后成卷的DTY丝卷切换掉,并重新进行新的DTY成卷操作,在此过程中,被切换掉的DTY丝卷的外表面上存在着过尾接头,其非常容易被清除,既可以保证DTY的等级质量,又可以避免去除太多卷绕DTY丝而浪费,同时通过自动检测过尾接头信息,避免了现有技术中过度依赖人工的干预而易出现的误记现象或漏记现象,提升了生产效率,降低了人工成本;
同时本例中的过尾接头的检测方法具体可以是应用在加弹机的生产过程中,并将所述检测通道设置在所述原丝架的解舒中心位置。
下面就上述生产方法与检测方法应用于国望高科纤维公司生产实验中加弹机上生产DTY(16锭)过程中跟踪确认过尾使用效果:

表4
初步结论:不同规格的涤纶丝品种50D、75D、100D和150D过尾确认,均能够实现检出率100%。
上述实施例只为说明本发明的技术构思及特点,其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施,并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰,都应涵盖在本发明的保护范围之内。
