Description

弹性纱线卷绕装置及弹性纱线切换卷绕方法 技术领域
本发明涉及弹性纱线卷绕技术，具体涉及一种弹性纱线卷绕装置及弹性纱线切换卷绕方法。
背景技术
如氨纶纤维等弹性纱线是一种连续的长丝，现有的弹性纱线生产成卷装通过卷绕装置结合辅助的纱线转换机构(如丝导引件)来实现自动卷装。
传统的卷绕装置包括一可以绕中心旋转的转台，在转台上对称设置有二个可以安装筒管且可以自由旋转的锭轴，其中一个锭轴处于卷绕弹性纱线的工作状态，另一锭轴处于等待状态，当卷绕的纱线达到满卷时转台转动以交换二个锭轴的位置，并通过丝导引件如同将弹性丝线在空筒管上绕一圈似的移动，将满卷锭轴上的弹性纱线切断并转换到空卷锭轴的筒管上继续卷装，由此实现弹性纱线的自动连续卷装。
随着弹性纱线生产技术的不断进步，弹性纱线的单位产能不断提高，例如氨纶纤维的生产中，目前每个纺丝位已经可以同时生产64根甚至更多数量的纱线。为了在有限的卷绕装置布局空间内满足高产能环境下的连续卷装需求，本发明申请人对上述传统的卷绕装置进行过改进，改进后的卷绕装置在一机架上左右对称设置有两套卷绕系统，每一卷绕系统包括一转台以及在该转台上设置的二个可交换位置的锭轴。改进后的卷绕装置结构紧凑，在相似或相同的布局空间内实现卷装产能的增加。但是，在上述结构紧凑的卷绕装置中，如丝导引件等纱线转换机构的安装很困难，两套卷绕系统之间的空间很小，难以满足各个转台的导引件沿锭轴绕圈式移动的空间需求，此外，为了安装纱线转换机构往往增加了卷绕装置自身结构的复杂度，使得故障频率大幅增加，而一旦出现如至少一根弹性纱线不能从满卷锭轴切换到带有空的筒管锭轴上等故障，就导致卷装的纱线转换失败，需要重新将纱线生头至锭轴上，费时费力；并且由于纺丝的连续性，每次从纱线转换失败到恢复卷绕期间都会产生一定数量的废品丝，特别是随着纱线根数的不断增多，该期间造成的废品丝的数量也相应增加，造成资源的浪费。

为使本发明实施例的目的、技术方案和优点更加清楚，下面将通过文字和/或结合附图对本发明实施例中的技术方案进一步进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，在本发明的一个附图或一种实施方式中描述的元素和特征可以与一个或更多个其它附图或实施方式中示出的元素和特征 相结合，为了避免因不必要的细节而模糊了本发明，在附图和说明中仅仅描述了与根据本发明的方案密切相关的装置结构和/或处理步骤，而省略了对与本发明关系不大的、本领域普通技术人员已知的部件和处理的表示和描述。基于本发明中的实施例，本领域普通技术人员在没有付出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本领域技术人员可以理解，本发明中的“第一”、“第二”等术语仅用于区别不同步骤、设备或模块等，既不代表任何特定技术含义，也不表示它们之间的必然逻辑顺序。
本发明实施例提供了一种弹性纱线卷绕装置，所述弹性纱线卷绕装置包括：
一机架，所述机架上左右对称设置有二个可绕自身中心旋转的转台，每个所述转台上对称设置有二个可设置筒管且可旋转的锭轴；
至少一驱动装置，用于控制二个所述转台反向旋转，使得每个所述转台上的二个锭轴交换位置；
至少一控制装置，一所述控制装置用于控制至少一所述转台上设置的二个锭轴形成速度差，以基于速度差使得一所述转台上弹性纱线从速度较慢的一锭轴的筒管切换至速度较快的另一锭轴的筒管继续卷绕。
上述卷绕装置可用于卷绕如氨纶纤维等弹性纱线，如果需要进行弹性纱线卷绕转换(即将弹性纱线从一个锭轴上的卷管转换到另一锭轴上的卷管以继续卷绕)，则可控制一机架上左右对称设置的二个转台反向旋转，使得每个所述转台上对称设置的二个锭轴交换位置，并控制每个所述转台上设置的二个锭轴形成速度差，以基于速度差使得每个所述转台上弹性纱线从速度较慢的一锭轴的筒管切换至速度较快的另一锭轴的筒管继续卷绕。
具体而言，采用上述弹性纱线卷绕装置进行弹性纱线的卷绕过程中，可将一纺丝位的多根待卷绕的弹性纱线分为二束，二束弹性纱线分别进入二个转台上设置的某一锭轴的筒管进行卷绕，实际应用中，每个转台的二个锭轴分别处于不同的位置，例如：在二个锭轴交换位置之前，一锭轴处于卷绕位置，位于卷绕位置的锭轴处于工作状态，弹性纱线卷绕在该锭轴设置的筒管上，不妨将弹性纱线卷绕转换前弹性纱线卷绕的筒管所在的锭轴称为“第一锭轴”；另一锭轴处于等待位置，位于等待位置的锭轴处于等待状态，在弹性纱线卷绕转换前该锭轴的筒管没有进行弹性纱线的卷绕，不妨将弹性纱线卷绕转换前等待卷绕弹性纱线的筒管所在的锭轴称为“第二锭轴”。需要说明的是，所述第一锭轴和所述第二锭轴是具有相对含义的，在本次弹性纱线卷绕转换中作为第一锭轴的某锭轴，在下一次弹性纱线卷绕转换中作为第二锭轴，反之亦然。
如果所述第一锭轴的筒管上卷绕的弹性纱线满足一定条件(所述条件可包括但不限于卷绕的弹性纱线达到预定量，或者，卷绕时间超过预定时长等等)，可控制该卷绕装置的二个转台反向旋转，通过每个转台的旋转来交换该转台设置的第一锭轴和第二锭轴的位置，即将第一锭轴由卷绕位置交换到等待位置、将第二锭轴由等待位置交换到卷绕位置。之后，可控制每个所述转台上设置的二个锭轴形成速度差，例如，对于每个转台而言，可增加第二锭轴的速度并使所述弹性纱线与所述第二锭轴的筒管相切之后减小第一锭轴的速度，基于二个锭轴形成的速度差，将所述弹性纱线转换卷绕到所述第二锭轴的筒管并拉断二个锭轴之间的所述弹性纱线，其中，所述第一锭轴为一所述转台上筒管卷绕所述弹性纱线的锭轴，所述第二锭轴为一所述转台上的另一锭轴，所述第二锭轴增加后的速度大于所述弹性纱线的速度且所述第一锭轴减小后的速度小于所述弹性纱线的速度。由于卷绕的弹性纱线为连续的长丝，其通常以一恒定的速度经旋转的接触辊等部件传动以卷绕到锭轴的筒管上，先增加第二锭轴的速度之后再减小第一锭轴的速度，可避免松弛的弹性纱线缠绕到如接触辊等其他部位，提高了弹性纱线卷绕到第二锭轴的成功率和稳定性。实际应用中，可在位置交换至弹性纱线与第二锭轴的筒管相切或即将相切时快速提升第二锭轴的方式来增加第二锭轴的速度，以提高控制的准确性。采用上述方案可完成弹性纱线卷绕的一次切换，纱线卷绕切换完成之后，弹性纱线在当前位于卷绕位置的锭轴的筒管上卷绕，此时可取下当前位于等待位置的锭轴上的卷装并换上空筒管。如果卷装再次完成，则采用上述方案再次进行弹性纱线卷绕的切换即可，如此反复多次，实现弹性纱线无中断的的连续收卷。
可见，本发明实施例提供的技术方案，无需在上述弹性纱线卷绕装置中设置如丝导引件等纱线转换装置，而是采用速度控制的方式实现该卷绕装置的二个转台各自锭轴的弹性纱线同时自动切换卷绕，即通过控制卷绕装置的一机架上左右对称设置的二个转台反向旋转，使得每个所述转台上对称设置的二个锭轴交换位置，并通过控制每个所述转台上设置的二个锭轴形成速度差，基于每个转台上的二个锭轴的速度差使得每个转台上弹性纱线从速度较慢的一锭轴的筒管切换至速度较快的另一锭轴的筒管继续卷绕。该方案减少了实现纱线卷绕切换的机械设计和制造等成本，简单易实现，大量应用实践表明，采用该方案进行纱线卷绕切换控制具有很高的成功率和可靠性，提高了如氨纶纤维等弹性纱线连续卷装的效率，降低故障率和成本。
本发明实施例提供的技术方案中，可通过一个或多个驱动装置控制二个转台的反向旋转以实现转台上锭轴的位置交换。例如：可通过二个驱动装置同时但分别控制一转台旋转，二个转台的转向相反，以实现二个转台同时反向旋转， 通过各转台的旋转带动各转台上设置的相应锭轴发生位置改变，直至每个转台上的二个锭轴完成位置交换；该方案可实现对每个转台的单独控制。或者，又例如：可通过一个驱动装置同步控制二个转台反向旋转，即二个转台在同一驱动装置同步驱动下反向旋转，通过各转台的旋转带动各转台上设置的相应锭轴发生位置改变，直至每个转台上的二个锭轴完成位置交换；该方案可保证二个转台转动的一致性，由此实现二个转台上的二个锭轴位置交换的同步性，进而有利于实现二个转台相应锭轴的弹性纱线同时自动切换卷绕。
可选的，可通过一个或多个控制装置对二个转台分别进行弹性纱线的自动切换卷绕进行控制。例如：所述至少一控制装置包括二个所述控制装置，一控制装置对应一转台，即一控制装置通过减小一转台上筒管卷绕弹性纱线的第一锭轴的速度并增加第二锭轴的速度，使第一锭轴速度减小后的速度小于弹性纱线的速度且第二锭轴速度增加后的速度大于弹性纱线的速度，基于二个锭轴形成的速度差，将弹性纱线切换到第二锭轴的筒管上卷绕并拉断二个锭轴之间的弹性纱线；该方案通过二个控制装置分别控制二个转台的锭轴进行弹性纱线的自动切换卷绕，提高了控制的方便性和灵活性。
可选的，一所述控制装置包括：至少一马达，一所述马达用于驱动一所述转台的至少一锭轴旋转；和/或，至少一控制器，一所述控制器用于控制至少一所述马达改变相应锭轴的速度。该方案可通过马达和控制器控制锭轴的速度，有利于实现锭轴的快速控制响应，如实现锭轴速度的快速降低或增加。所述马达和/或所述控制器的数量可根据实际控制的需要灵活确定。例如：每个转台上的二个锭轴可共用一个马达分时进行控制，如通过一马达先控制一转台的第一锭轴迅速减速，之后再控制该转台的第二锭轴迅速加速，基于二个锭轴形成的速度差，将弹性纱线切换到第二锭轴的筒管上继续卷绕并拉断二个锭轴之间的弹性纱线。又例如：每个转台上的二个锭轴可分别用不同的马达独立进行控制,提高锭轴速度控制的灵活性，即所述至少一马达可包括：二个马达，一马达用于驱动一转台的一锭轴旋转，另一马达用于驱动该转台的另一锭轴旋转，参考图2所示；该情形下，二个马达可通过同一控制器进行统一控制，以提高卷绕装置控制的集成度；或者，二个马达可通过不同的控制器独立进行控制，以进一步提高速度控制的灵活性。
本发明实施例提供的技术方案采用速度控制的方式实现一卷绕装置的二个转台中每个转台不同锭轴的弹性纱线的自动切换卷绕，为了提高每个转台弹性纱线卷绕的切换成功率和可靠性，可在该转台的二个锭轴交换到指定位置时快速形成二个锭轴的速度差，即快速减小第一锭轴的速度并快速增加第二锭轴的速度。其中，减小所述第一锭轴的速度的实现方式非常灵活。例如：可通过 控制用于驱动第一锭轴的马达制动的方式，快速减小马达的速度，马达速度的快速下降就会带动第一锭轴速度的快速下降；该方案可复用控制器控制用于驱动第一锭轴的马达制动来实现第一锭轴速度的迅速降低，电控实现方式简单可靠，且无需额外增加部件，有利于节约成本。又例如：可制动用于驱动所述第一锭轴的马达以快速减小所述第一锭轴的速度；该方案可通过设置制动器的方式(不妨称为“第一制动器”)，通过第一制动器快速制动用于驱动第一锭轴的马达，由此通过机械制动的方式实现第一锭轴速度的迅速降低，且第一制动器的安装位置非常灵活。再例如：可制动所述第一锭轴以快速减小所述第一锭轴的速度；该方案也可通过设置制动器的方式(不妨称为“第二制动器”)，通过第二制动器快速制动第一锭轴，由此通过机械制动的方式实现第一锭轴速度的迅速降低，且第二制动器的安装位置非常灵活。此外，可控制用于驱动所述第二锭轴的马达加速，以增加所述第二锭轴的速度，该方案可复用控制器控制用于驱动第二锭轴的马达加速来实现第二锭轴速度的迅速提升，电控实现方式简单可靠，且无需额外增加部件。
可选的，可通过对转台旋转停止控制，使得转台停止旋转时第二锭轴位于便于卷绕弹性纱线的位置，以提高每个转台弹性纱线卷绕到第二锭轴的成功率。例如，控制二个所述转台反向旋转，包括：控制二个所述转台开始反向旋转；确定至少一所述转台的旋转是否满足预定条件；如果是，则停止至少一所述转台的旋转，即一转台的旋转满足预定条件则停止该转台的旋转。相应的，弹性纱线卷绕装置还可包括：至少一检测部件，用于确定至少一所述转台的旋转是否满足预定条件；所述至少一驱动装置用于控制二个所述转台开始反向旋转，并在至少一所述检测部件确定至少一所述转台的旋转满足预定条件时，停止至少一所述转台的旋转。所述预定条件可根据便于卷绕弹性纱线的需求预先确定，所述预定条件可包括但不限于某一指定位置或已旋转预定角度等等，所述检测部件可包括但不限于临近传感器、角度传感器等等。可选的，一转台停止旋转时，所述弹性纱线与该转台上的第二锭轴的筒管的相切包角大于预定角度，所述预定角度可为4°-6°，如所述预定角度为5°，大量应用实践表明，采用该方案进行转台旋转停止控制，弹性纱线松弛时卷绕到第二锭轴的筒管上的成功率和可靠性都很高。
可选的，本发明实施例提供的弹性纱线卷绕装置还可包括：每个所述转台的上方设置有一用于控制卷装成形的可旋转的接触辊，处于工作状态时，所述接触辊压在处于卷绕位置的锭轴的筒管上(如筒管上已经卷绕有弹性纱线，则压在卷装上)以控制卷装成形。在二个接触辊中心的上方可设置有一可旋转的横动辊，横动辊的两侧分别设置有一横动导丝器，横动导丝器与转台对应，一 横动导丝器可在所述横动辊旋转时横向往复移动以将弹性纱线横向铺设在相应转台的锭轴的筒管上来形成卷装。
进一步，可选的，所述二个接触辊可自由旋转地支撑在至少一接触辊支架上(如二个接触辊分别支撑在二个接触辊支架上等)。所述横动辊可旋转地支撑在一横动辊支架上。接触辊支架和横动辊支架可共同连接一滑动箱，滑动箱可在导轨上上下移动，如随着筒管卷绕的卷装尺寸的逐渐增加，滑动箱沿导轨逐渐向上移动。
在如氨纶等弹性纱线的收卷控制过程中，卷装的尺寸相对非弹性纱线而言要小得多，以保证品质的均一性。采用该方案实现收卷自动控制，共用同一接触辊、滑动箱随着卷装上下移动等一个或多个设计有利于减小卷绕装置的体积，提高空间利用率，可更好满足弹性纱线单位产能不断提高的工艺趋势的收卷控制需求。
下面结合图1和图3a-图3e，进一步说明本发明实施例提供的可选弹性纱线卷绕装置及弹性纱线卷绕切换的可选工作过程。弹性纱线卷绕装置在一机架上包括二个左右对称的卷绕系统，每个卷绕系统具有相同或相似的部件，以下采用在相同或相似部件的附图标记用相同数子后面加“A”和“B”的方式区分左右，用相同数子后面不加“'”和加“'”的方式区分同一转台的二个不同锭轴，以便于描述。
可选的，弹性纱线卷绕装置包括在一机架1上设置有二个可以绕其中心旋转的转台2A、2B，二个转台2A、2B的可旋转方向相反，在转台2A、2B上各对称设置有二个可以自由旋转的锭轴，每个锭轴上安装有筒管9A、9B，筒管上卷绕的弹性纱线卷装，用10A、10B表示。位于转台2A、2B上位的锭轴8A、8B处于工作状态(锭轴8A、8B此时相当于本发明实施例所述的第一锭轴，也可根据卷装的特点称其为满卷锭轴)，位于转台2A、2B下位的锭轴8A'、8B'处于等待状态(锭轴8A'、8B'此时相当于本发明实施例所述的第二锭轴，也可根据卷装的特点称其为空卷锭轴)。
在锭轴8A、8B的上方设置有接触辊6A、6B，接触辊6A、6B可自由旋转地支撑在接触辊支架7A、7B上，并压在卷装10A、10B上控制卷装的成形；在接触辊6A、6B中心的上方设置有横动辊4，横动辊4可以自由旋转地支撑在横动辊支架3上，横动辊4的两侧设置有横动导丝器5A、5B，横动导丝器5A、5B可在横动辊4旋转时横向往返移动，横动导丝器5A、5B的横向往返移动可以使弹性纱线横向的铺设以形成卷装10A、10B；接触辊支架7A、7B及横动辊支架3共同连接在滑动箱12，滑动箱12可以在导轨13A、13B上上下移动。
在弹性纱线卷绕过程中，连续的多根弹性纱线被等分为两束11A、11B，并 通过接触辊6A、6B后在上位安装有筒管9A、9B的锭轴8A、8B上进行卷绕，横动导丝器5A、5B带动纱线横向的往返移动铺设成卷装10A、10B。随着卷装10A、10B的直径不断增大，滑动箱12带着接触辊6A、6B和横动辊4一起向上沿着导轨13A、13B进行移动。
当上位的锭轴8A、8B的筒管9A、9B上的卷装10A、10B达到预定要求时，二个转台2A、2B反向转动，如图3a所示，通过各转台的转动使各转台设置的二个锭轴交换位置，位置交换后的锭轴状态如图3b所示，此时弹性纱线11A、11B仍然在8A、8B的筒管9A、9B上卷绕，并且弹性纱线11A、11B与交换位置后的位于上位的锭轴8A'、8B'上的筒管9A、9B一定程度上包裹相切，相切包角大于5°。此时增加交换位置后位于上位的锭轴8A'、8B'的速度使之大于弹性纱速度旋转，这样可使接触辊6A、6B与交换位置后位于上位的锭轴8A'、8B'之间的纱线具有张力，避免纱线卷绕到接触辊6A、6B上。之后对交换位置后的位于下位的锭轴8A、8B进行快速制动，使其速度快速下降，如图3c所示，这样就使交换位置后的位于下位的锭轴8A、8B与交换位置后位于上位的锭轴8A'、8B'之间的弹性纱线松弛，随着交换位置后的位于下位的锭轴8A、8B速度的进一步降低，松弛的弹性纱线就卷绕到交换位置后位于上位的锭轴8A'、8B'的筒管9A、9B上，如图3d所示。当弹性纱线卷绕到锭轴8A'、8B'的筒管9A、9B之后，锭轴8A'、8B'与锭轴8A、8B之间的弹性纱线的拉紧张力不断增大，弹性纱线被逐渐拉紧直到弹性纱线断裂，这样弹性纱线就单独在交换位置后位于上位的锭轴8A'、8B'的筒管9A、9B上继续进行卷绕来生产新的卷装，如图3e所示。而交换位置后的位于下位的锭轴8A、8B速度连续降低直至停止，停止后可取出成品的卷装10A、10B，并安装上新的空的筒管直到下次卷绕切换，如此反复，连续的弹性纱线就可以通过卷绕装置连续不断生产出成品卷装。
