Abstract
本发明的一个目的是可以提供一种帘线,尤其是用于增强橡胶物品的帘线,其中,通过以稳定和可靠的方式用橡胶涂覆作为帘线的组成部分的线材而提高橡胶浸入性。通过如下方式制造本发明的帘线:当将金属线材引导至挤出机并且从挤出机的口模将金属线材与橡胶一起挤出以使得金属线材被橡胶涂覆时,将多根金属线材并置在口模中,并且将金属线材与橡胶一起挤出。
Description
技术领域
本发明涉及一种用橡胶涂覆金属线材(filament)的方法,其中,该金属线材作为例如用于增强橡胶物品的帘线的组成部分、一种由捻线机(filament twisting machine)加捻作为帘线的组成部分的金属线材而制造帘线的方法、一种由捻线机加捻橡胶涂覆的金属线材而形成的帘线、一种用于给金属线材涂覆橡胶的橡胶涂覆设备以及一种帘线制造设备。
背景技术
用于增强橡胶物品的帘线尤其是用于增强轮胎的帘线需要具有多种特性。首先,用于增强轮胎的帘线需要能够抑制帘线耐久性的恶化,该恶化是由进入轮胎内部的水分引起的腐蚀的传播引起的。
具体地,当水分由于轮胎的外部破损而进入轮胎内部并且水分到达帘线时,帘线由于该水分而遭受腐蚀。在此情况下,如果帘线内部存在间隙,那么水分经由该间隙在帘线的长度方向上传播,由此沿着帘线扩大腐蚀区域。结果,帘线的耐久性由于该腐蚀而恶化。
因此,为了抑制帘线的腐蚀,需要用橡胶充分地填充帘线内部的间隙,防止水分沿帘线的长度方向传播。
考虑到上述问题,日本特开2002-302884号公报和日本特开2002-302885号公报均提出了在未硫化橡胶涂覆机中用未硫化的橡胶涂覆各线材的技术;然后通过分线机(line-partingmachine)(引导器)分开涂覆有未硫化橡胶的各线材,并且将分开的线材供给到聚束捻线机(buncher twisting machine);同时通过使用聚束捻线机来加捻这些涂覆有未硫化橡胶的线材,从而制造帘线。
此外,日本特开2002-266266号公报提出了如下技术:通过使用橡胶挤出机(extruder)而用未硫化的橡胶涂覆作为多根捻在一起的线材的芯的周面;使用聚束捻线机在涂覆有未硫化橡胶的芯的周围加捻形成鞘(sheath)的多根线材,从而形成帘线。
发明内容
发明要解决的问题
然而,在日本特开2002-302884号公报和日本特开2002-302885号公报公布的技术中,因为各线材将被分别涂覆未硫化的橡胶,所以在经由引导器收束线材的过程中使涂覆有未硫化的橡胶的线材与引导器接触时,未硫化的橡胶趋向于从线材上脱落,由此线材最终将处于没有充分地被未硫化橡胶涂覆的状态。此外,因为已经脱落的未硫化橡胶阻塞引导器,所以存在线材不能通过引导器的可能性。
此外,在日本特开2002-266266号公报的技术的情况下,当芯的周围通过橡胶挤出机被涂覆橡胶时,源自于聚束捻线机的扭曲(twist)传递到将形成芯的线材。例如,当使用三根线材时,在该芯具有1×3的扭曲结构的状态下,由未硫化的橡胶涂覆该芯。结果出现这样的问题:线材的芯部产生没有填充未硫化橡胶的闭合空间。
考虑到上述问题,本发明的一个目的是可以提供一种帘线,尤其是一种用于增强橡胶物品的帘线,其中,通过以稳定和可靠的方式用橡胶涂覆作为帘线的组成部分的线材而提高帘线的橡胶浸入性。
用于解决问题的方案
作为对用于实现上述目的方案的锐意研究的结果,本发明的发明人已经发现能够通过如下方式能够以可靠和稳定的方式用橡胶涂覆线材:当用橡胶涂覆线材时,水平地放置这些线材,用橡胶涂覆这些线材,并且抑制当所述线材被加捻成帘线时由捻线机产生的线材的扭曲,从而完成本发明。
具体地,本发明的要点如下:
(1)一种由橡胶涂覆金属线材的方法,其特征在于,当将所述金属线材引导至挤出机并且从所述挤出机的口模(mouthpiece)将所述金属线材与橡胶一起挤出以使得所述金属线材被橡胶涂覆时,将多根所述金属线材并置在所述口模中,并且将所述多根金属线材与橡胶一起挤出。
(2)一种帘线的制造方法,其特征在于,当金属线材被引导至挤出机、多根所述金属线材被并置在所述挤出机的口模中并且从所述口模将所述多根金属线材与橡胶一起挤出,然后将由此涂覆有橡胶的所述多根金属线材供给到捻线机以制造帘线时,在所述口模的出口侧消除从所述捻线机传递到由此涂覆有橡胶的所述多根金属线材的扭曲。
(3)根据上述(2)的帘线的制造方法,所述捻线机是聚束型捻线机;
(4)一种帘线,其具有加捻的单层结构,通过对上述(1)所述的方法涂覆有橡胶的多根金属线材进行加捻而形成所述帘线;
(5)一种帘线,其具有单捻双层(single twist doublelayered)结构,通过将作为鞘的多根金属线材配置于由上述(1)所述的方法涂覆有橡胶的、作为芯的多根金属线材的周围,并且同时加捻所述芯和所述鞘而形成所述帘线;
(6)一种帘线,其具有双捻双层(double twist doublelayered)结构,通过在由(2)所述的方法制造的作为芯的帘线周围加捻作为鞘的多根金属线材而形成所述帘线;
(7)一种橡胶涂覆设备,所述橡胶涂覆设备包括挤出机和口模,其特征在于,所述口模的宽度允许在所述口模中以并置的方式配置多根金属线材。
(8)一种帘线制造设备,所述帘线制造设备包括捻线机以及如上述(7)所述的橡胶涂覆设备,其特征在于,所述帘线制造设备还包括扭曲消除机(twist-eliminating machine),所述扭曲消除机被布置于所述橡胶涂覆设备的出口侧,用于消除从所述捻线机传递到金属线材的扭曲。
(9)上述(8)所述的帘线制造设备,其特征在于,所述扭曲消除机是多槽滑轮(pulley)系统。
根据本发明,通过在挤出机的口模中并置多根金属线材并且用橡胶一次涂覆这些并置的金属线材,能够以稳定和可靠的方式用橡胶涂覆多根金属线材。结果,能够在金属线材不经历橡胶从其上脱落的情况下将金属线材加捻成帘线。此外,通过在口模的出口侧消除从捻线机传递到金属线材的扭曲能够抑制金属线材的扭曲,由此,能够以稳定和可靠的方式用橡胶涂覆线材。结果,能够得到具有优异的耐久性的帘线。

具体实施方式
以下将详细说明本发明。将参考附图说明本发明的用橡胶涂覆金属线材的方法。首先,图1示出了加捻金属线材以制造帘线的工艺。在图1中,多根(图中是3根)金属线材1被供给到橡胶涂覆设备2,从而用橡胶3涂覆金属线材1,并且使涂覆有橡胶3的金属线材1a经由扭曲消除机4而穿过引导器5。然后,通过收束部6收束金属线材1a,并且将金属线材1a供给到捻线机7,并且由捻线机7加捻金属线材1a,由此制造帘线8。
这里,将参考图2详细说明用橡胶涂覆金属线材1的工艺。橡胶涂覆设备2具有用于同时挤出橡胶和被引入的金属线材1的挤出机和用于限制挤出结构的口模。因为挤出机具有传统的结构,所以图2只示出了口模。具体地,如图2中的口模9的宽度方向上的剖面图所示,口模9的开口宽度允许以多根金属线材1在口模9中并置的方式从该口模的入口侧将多根金属线材1引入口模9,使得金属线材1的周围一次被这些橡胶3涂覆,并且与橡胶3一起被挤出而成为金属线材1a。在本实施方式中,为了将金属线材1并置在口模9中而将其引入口模9,优选地,在将金属线材1引入口模9之前,通过使用引导器来并置各金属线材1。
通过在口模9中并置金属线材1,如上所述地用橡胶3涂覆金属线材1并且挤出涂覆有橡胶3的金属线材1a,当金属线材1a被供给到捻线机7时,能够沿着联接橡胶涂覆设备2和捻线机7的路线(pass line)直线地供给金属线材1a,由此能够防止金属线材1a与引导器5接触。结果,因为防止了金属线材1a与引导器5的接触,橡胶3不会从金属线材1a上脱落,由此可靠地涂覆有橡胶的各金属线材1a能够被供给到捻线机7。
此外,因为金属线材1a在不与引导器5接触的状态下行进,所以从金属线材1a上脱落的橡胶不可能阻塞引导器的通孔。因此,能够防止橡胶3阻塞引导器5的通孔使得金属线材1a不能再穿过引导器5的通孔的情况的发生。
接着,将说明通过加捻根据前述方法涂覆有橡胶的金属线材1a而制造帘线的程序。首先,多根金属线材1被并置在口模9中,并且与橡胶一起被挤出。重要的是,当金属线材1a被供给到捻线机7以制造帘线时,在口模9的出口侧消除从捻线机7传递到金属线材1a的扭曲。具体地,金属线材1a经由扭曲消除机4被供给到捻线机7,该扭曲消除机4用于消除从捻线机7尤其是聚束捻线机传递到各金属线材1a的扭曲,并且通过捻线机7对金属线材1a进行加捻而制造帘线8,由此能够制造内部被可靠地填充了橡胶的帘线。
因为消除了从捻线机7传递到金属线材的扭曲,所以当在口模9中用橡胶3涂覆金属线材1时,金属线材1不彼此缠绕。换句话说,金属线材1能够在不彼此纠缠从而不在其芯部产生闭合空间的情况下被橡胶3涂覆。结果,各金属线材1的周围均能够可靠地涂覆橡胶3,由此,例如,在通过使用三根金属线材制造具有1×3结构的帘线的情况下,这三根金属线材预先被涂覆橡胶,从而能够制造线材之间的中心部分能够充分地渗透橡胶的帘线。因此,能够抑制上述的由于水分而产生的腐蚀的传播,并且能够制造具有优异的耐久性的帘线。
在本发明中,在帘线制造中用于使金属线材1a彼此缠绕的捻线机是聚束型捻线机,在金属线材中不可避免地产生扭曲,因此应用本发明特别有效。如上所述地制造的帘线是具有诸如1×n(n≥3)等的加捻的单层结构的帘线。
此外,如图3所示,通过如下步骤能够制造根据本发明的另一种帘线:将将形成鞘的多根(图中是9根)线材1b引导到前述的涂覆有橡胶的金属线材1a的周围,然后引入到引导器5;在收束部6中收束金属线材1a和金属线材1b;然后通过捻线机7同时地加捻金属线材1a和金属线材1b,从而制造具有单捻双层结构的帘线。
简言之,在帘线具有双层结构的情况下,通过使用前述金属线材1a作为单捻双层结构的帘线的芯,能够实现帘线的芯的内部没有间隙地完全填充橡胶的帘线结构。
此外,先将通过如图1所示的一系列步骤制造的帘线卷绕在线轴上,并且在图4所示的工艺中,将如此卷绕在线轴11上的帘线从线轴11上引出,并将该帘线供给到扭曲消除机4,然后使该帘线穿过引导器5,在收束部6中将将形成鞘的金属线材收束到帘线8的周围,并且通过捻线机7对所述帘线和所述金属线材进行加捻,从而使用卷绕在线轴11上的帘线作为芯来制造具有双捻双层结构的帘线。可以从捻线机7中拉出如此加捻的帘线,然后卷绕在线轴上,或卷绕在捻线机7内部的线轴上。
用于用橡胶3涂覆多根金属线材1的设备包括上述挤出机和口模9。口模9必需具有如下宽度:该宽度允许多根金属线材1以在口模9中并置的方式布置。
具体地,因为口模9具有允许多根金属线材1以在口模9中并置的方式布置的宽度,因此,多根金属线材1能够被并置在口模9中,从而能够用橡胶3一次涂覆这些金属线材1。结果,能够避免金属线材1与引导器5接触,因此能够防止发生橡胶3从金属线材1a上脱落的情形。
在本实施方式中,优选地,能够将多根金属线材1以并置的方式布置在其中的口模9优选地具有通过下面的公式(1)计算出的宽度W。公式(1)中的“A”是考虑到如图6所示的B而通过下面的公式(2)计算出的值。
注意:
宽度W(mm)=金属线材的直径t(mm)×(将用橡胶涂覆的金属线材的数目-1)+t×A (1)
A:(间隙B×2+金属线材的直径t)/金属线材的直径t(2)
(优选地,A等于或大于1.2)
此外,在包括捻线机7和具有挤出机和口模的橡胶涂覆设备2的帘线制造设备中,重要的是在橡胶涂覆设备2的出口侧设置扭曲消除机4,该扭曲消除机4用于消除从捻线机7传递的扭曲。通过在橡胶涂覆设备2的出口侧设置用于消除扭曲的传递的扭曲消除机4,能够消除从捻线机7传递至金属线材的扭曲。结果,在通过橡胶涂覆设备2用橡胶3涂覆金属线材1的过程中,在金属线材不扭曲的情况下,各金属线材1均被橡胶3涂覆,由此能够以可靠和稳定的方式实现橡胶的涂覆。
只要扭曲消除机4被设置于橡胶涂覆设备2的出口侧和引导器5之间,那么用于消除从捻线机7传递至金属线材的扭曲的扭曲消除机4就能够消除来自捻线机7的扭曲。因此,扭曲消除机4的布置不限于图1或图3所示的位置。
可以使用如图5所示的多槽滑轮作为上述的扭曲消除机。具体地,通过使金属线材多次通过均具有多个槽的上下一对多槽滑轮能够消除扭曲的传递。
实施例
通过使用具有将表1中所示的A值分别代替公式(1)中的A而计算出的宽度的口模并通过如图3所示的帘线制造工艺制造均具有3+9×022(mm)的结构的帘线,其中,该帘线制造工艺包括:并置三根金属线材,用橡胶涂覆金属线材,在三根金属线材周围加捻将形成鞘的九根金属线材。评价由此获得的各帘线的橡胶浸入性。结果如表1所示。关于传统例的帘线,通过传统的橡胶涂覆方法用橡胶涂覆构成帘线的金属线材。
通过在各帘线的沿与帘线轴向正交的方向剖切的截面中,观察橡胶涂覆区域而测定橡胶浸入性。
表1
传统例 | 发明例1 | 发明例2 | 发明例3 | |
A的值 | - | 1.08 | 1.2 | 1.32 |
宽度W(mm) | - | 0.678 | 0.704 | 0.730 |
橡胶浸入性 | 15 | 67 | 82 | 98 |
从表1的结果可知,与传统例的帘线的橡胶浸入性相比,发明例的帘线的橡胶浸入性显著提高。
