相关专利申请的交叉引用
本申请要求2018年9月24日提交的美国临时专利申请号62/735,799的权益，该专利申请的公开内容据此以引用方式并入本文。
技术领域
本公开整体涉及用于将材料涂覆到基底的涂覆器系统，并且更具体地涉及在用于将材料涂覆到织物的涂覆器系统中使用的喷嘴组件。
背景技术
在服装制造领域中，涂覆器系统通常用于将材料诸如聚氨酯(PUR)胶涂覆到织物或布料，以将一块块的织物或布料粘结在一起。当将一块块的织物粘结在一起时，需要能够以高精确度和准确度喷涂少量材料的涂覆器系统。例如，要涂覆到织物的期望材料条带的宽度可具有小于8mm的宽度和小于0.2mm的高度要求。在许多现有的涂覆器系统中，材料以低水平的精确度和准确度喷涂，这可导致喷涂过量的材料。
此外，涂覆器系统难以调节以形成所分配材料的期望图案。通常，不将足够多的材料涂覆到织物上以形成足够强的粘结。如果期望更多的材料，则运行单独的涂覆过程，从而导致制造时间延长、机械磨损增大并且成本增加。
因此，需要一种涂覆器系统，该涂覆器系统可被调节成以期望的图案和量精确地喷射材料，而不需要过长的涂覆时间。
发明内容
上述需求通过本发明所公开的涂覆器系统和喷嘴组件的各种实施方案来满足。根据一个实施方案，一种用粘合剂粘结织物的方法包括将粘合剂从粘合剂供应源接收到喷嘴组件中。喷嘴组件具有阀座、被构造成朝向和远离阀座可滑动地移动的阀杆、以及多条出口通道。该方法还包括将粘合剂从多条出口通道喷射到第一织物上，并且将第二织物施用到第一织物以将第一织物和第二织物彼此粘附。
根据另一个实施方案，一种用于喷射粘合剂以粘结织物的喷嘴组件包括主体，该主体在入口和出口之间限定其中的腔室。该腔室被构造成通过入口接收粘合剂并且允许粘合剂通过出口离开。喷嘴组件还包括：阀座，该阀座邻近出口设置；阀杆，该阀杆被构造成在腔室内朝向和远离阀座可滑动地移动并且接触阀座；以及多条出口通道，该多条出口通道与腔室的出口流体连通。多条出口通道中的每条出口通道被构造成接收来自腔室的粘合剂。阀杆被构造成冲击阀座，使得由于阀杆和阀座之间的冲击动量，将离散体积的粘合剂从多条出口通道中强行喷出到织物上。
根据另一个实施方案，一种用于将粘合剂喷射到织物上的涂覆器系统包括材料供应源，该材料供应源用于存储粘合剂；泵，该泵流体连接到材料供应源；阀，该阀用于控制泵的操作；以及喷嘴组件，该喷嘴组件被构造成从泵接收粘合剂并将粘合剂喷射到织物上。喷嘴组件包括主体，该主体在入口和出口之间限定其中的腔室，并且该腔室被构造成通过入口接收粘合剂并且允许粘合剂通过出口离开。喷嘴组件还包括：阀座，该阀座邻近出口设置；阀杆，该阀杆被构造成在腔室内朝向和远离阀座可滑动地移动并且接触阀座；以及多条出口通道，该多条出口通道与腔室的出口流体连通。多条出口通道中的每条出口通道被构造成接收来自腔室的粘合剂。阀杆被构造成冲击阀座，使得由于阀杆和阀座之间的冲击动量，将离散体积的粘合剂从多条出口通道中强行喷出到织物上。

现在将参考附图详细描述本公开的各方面，其中除非另外指明，否则类似的参考标号始终是指类似的元件。
具体实施方式
本文描述了涂覆器系统10和用于将材料喷涂到基底上的相关喷嘴组件100。在以下描述中，某些术语仅为方便起见用于描述涂覆器系统10而非限制性的。词语“右”、“左”、“下”和“上”表示附图中作为参考的方向。词语“内”和“外”分别是指朝向和远离描述内容的几何中心的方向，用于描述涂覆器系统10及其相关部分。词语“向前”和“向后”是指沿纵向方向2的方向和沿着涂覆器系统10及其相关部分与纵向方向2相反的方向。术语包括上面列出的词语、其衍生词和具有类似含义的词语。
除非本文另外指明，否则术语“水平”、“横向”和“竖直”用于描述涂覆器系统10的各个部件的正交方向分量，如纵向方向2、横向方向4和竖直方向6所表示的那样。应当理解，虽然将纵向方向2和横向方向4图示为沿着水平面延伸，并且竖直方向6沿着垂直于水平面的方向延伸，但涵盖各个方向的平面在使用期间可不同。
参见图1至图4，涂覆器系统10包括用于储存所供应材料的材料供应源12。材料可由预包装注射器(未示出)中的材料供应源12接收，直接填充到限定在材料供应源12内的贮存器中，或者从与涂覆器系统10间隔开的外部供应源(未示出)泵送到材料供应源12。在一些实施方案中，材料可为胶，诸如聚氨酯(PUR)胶，但也可设想其他材料。材料供应源12可被构造成当材料保留在材料供应源12内时将材料熔融和/或保持在高温下。在一些实施方案中，材料供应源12可被设计成保持至多300立方厘米(cc)的材料，但是材料供应源12可根据需要更大或更小。材料供应源12可包括加热元件(未示出)以向材料供应源12内的材料提供热量，或者另选地，保持材料供应源12内的期望温度。这防止材料在被分配时冷却，因此保留所期望的材料流动特性。在一些实施方案中，涂覆器系统10可包括第二加热元件(未示出)，该第二加热元件被构造成将材料(例如，粘合剂)保持在与上述加热元件不同的温度下。
涂覆器系统10也包括流体连接到材料供应源12的泵16。泵16可包括主体31，该主体包括顶部部件32a和附接到顶部部件32a并定位在该顶部部件下方的中间部件32b。应当理解，泵16可另选地限定一体式主体或具有任何其他数量的部件。
泵16的主体31限定基本上中空的主体，使得上部腔室36和下部腔室38限定在主体31内。密封包40定位在主体31内并且将主体31的内部分成上部腔室36和下部腔室38。
喷嘴100能够可移除地联接到主体31并且定位在例如中间部件32b下方。喷嘴100可选自各自被构造成喷射不同图案的多个喷嘴100。在另选的实施方案中，喷嘴100可为一体式主体31的一部分。下部腔室38可设置在喷嘴100内。阀座104设置在下部腔室38的下端处并且由喷嘴100限定。多条出口通道108邻近阀座104设置并且延伸穿过喷嘴100。多条出口通道108与下部腔室38流体连通。
泵16也包括定位在主体31内的击发销48。击发销48限定上端48a和阀杆48b，该阀杆从上端48a沿竖直方向6延伸。上端48a定位在上部腔室36内，而阀杆48b从上端48a延伸穿过上部腔室36，穿过密封包40，并进入下部腔室38中。
在操作中，击发销48被构造成在主体31内在回缩位置和伸出位置之间往复运动。该往复运动可由通过第一空气路径52a和第二空气路径52b流入上部腔室36中的加压空气引起。第一空气路径52a和第二空气路径52b中的每一者可从阀20接收加压空气，该阀通过连接器24连接到泵16。根据需要，阀20可为气动阀、电子阀或任何其他类型的阀。击发销48的上端48a将上部腔室36分成第一部分36a和第二部分36b，其中第一部分36a可从第一空气路径52a接收加压空气，并且第二部分36b可从第二空气路径52b接收加压空气。当加压空气流过第一空气路径52a并进入上部腔室36的第一部分36a时，击发销48沿着竖直方向6被向下驱动到伸出位置中。相比之下，当加压空气流过第二空气路径52b并进入上部腔室36的第二部分36b时，击发销48沿着竖直方向6被向上驱动到回缩位置中。
继续参见图1至图4，泵16包括限定在喷嘴100的外表面和中间部件32b的内表面之间的周向腔室54。周向腔室54流体连接到材料供应源12，使得周向腔室54被构造成从材料供应源12接收材料并允许材料流过周向腔室54以到达限定在喷嘴100内的径向孔56。然后材料可流过径向孔56到达下部腔室38。在一些实施方案中，径向孔56包括围绕喷嘴100周向等距间隔开的四个径向孔。然而，设想径向孔56可包括更多或更少的孔，以及具有非等距间距的孔。
当击发销48处于回缩位置时，阀杆48b与由喷嘴100限定的阀座104间隔开。在该位置中，材料流过周向腔室54，流过径向孔56，并进入下部腔室38中。然后，当击发销48转变到伸出位置时，击发销48的阀杆48b沿着竖直方向6朝向阀座104快速向下移动穿过下部腔室38。在该转变期间，击发销48致使下部腔室38内的一定量的材料通过出口通道108排出。当处于伸出位置时，阀杆48b的下端可接触阀座104，并且因此在下部腔室38和出口通道108中的每个出口通道之间形成流体密封，或者可定位在阀座104的稍上方。
当击发销48沿竖直方向6从回缩位置转变到伸出位置时，击发销48行进一段距离，该距离可被称为行程长度。所需的行程长度可随分配操作、所分配材料的类型、内部部分随时间的磨损等而变化。因此，行程长度可使用限制杆44来调节，该限制杆延伸穿过主体31的顶部部件32a并且进入上部腔室36的第一部分36a中。当击发销48处于回缩位置时，上端48a可接触限制杆44的下端，使得限制杆44控制击发销48在回缩位置向上移动多远。限制杆44可通过螺纹接合顶部部件32a，使得限制杆44相对于顶部部件32a的旋转使限制杆44进一步移入或移出上部腔室36，因此改变击发销48在回缩位置的最大向上位置，并且同样改变行程长度。
参见图4至图7，喷嘴100可包括三条出口通道108，但应当理解，喷嘴100可包括另一合适数量的出口通道108，例如，一条、两条、四条、五条或六条出口通道。例如，图9和图10所描绘的例示性实施方案示出了分别具有一条出口通道108和两条出口通道108的合适喷嘴100。出口通道108中的每条出口通道可与竖直方向6成介于0°和90°之间的角度设置。在一些实施方案中，出口通道108中的一些出口通道或全部出口通道可平行于其他出口通道108中的一条或多条出口通道，并且可沿竖直方向6设置。出口通道108中的每条出口通道的特定角度可取决于阀座104的尺寸和/或形状、阀杆48b的尺寸和/或形状、正在分配的材料，取决于从出口通道108中的每条出口通道分配的液滴之间的期望距离，或取决于其他制造要求和/或偏好。
当击发销48从回缩位置转变到伸出位置，然后从伸出位置转变回到回缩位置时，这可被称为行程。利用每个行程，喷嘴100的下部腔室38内的材料移动穿过出口通道108。击发销48被构造成冲击阀座104，使得由于阀座104和击发销48的阀杆48b之间的冲击动量，将离散体积的材料从喷嘴朝向基底200强行喷出(即喷射)。喷射与挤出或其他类型的材料分配形成对比，其中液体材料被分配为连续的细长长丝，一般被称为粘合剂的“珠”。虽然可通过在液体材料挤出期间快速打开和关闭阀或通过在分配所挤出的珠时使用空气将其打碎来形成材料液滴，但这些方法明显不同于喷射方法，在喷射方法中，当击发销48撞击阀座104时，离散的液体块以高速直接从分配器快速喷出。液体材料(例如，粘合剂)在低压下被接收到下部腔室38中，并且在较高压力下从下部腔室38喷射出。随着阀杆48b朝向阀座104移动，产生高压。当阀杆48b冲击阀座104时，液体材料的一部分(以液滴或圆点的形式)可从喷嘴组件100脱离。因此，在一些实施方案中，所喷射的材料可在接触基底200之前与喷嘴组件100分离。
通过提供多条出口通道108，单个行程可导致多个液滴从喷嘴100分配到基底200上。应当理解，行程长度、存在于下部腔室38中的材料的量、以及出口通道108的数量和尺寸均为可被修改以实现期望分配的参数。
在图4至图7的示例性实施方案中，在喷嘴100中描绘了三条出口通道108。在击发销48的每个行程中，三个单独的液滴从喷嘴100喷射到基底200上(参见图8)。这允许同时分配更多的材料，从而导致制造时间缩短并且相关的成本降低。出口通道108的数量和布置可基于期望的用途进行调节，这增加了每个分配装置和喷嘴100的通用性。
分配到基底200上的相邻液滴之间的距离可由出口通道108之间的距离和每条出口通道108相对于竖直方向6的角度来控制。另选地或除此之外，可通过移动喷嘴100更靠近或更远离基底200来改变所分配液滴之间的距离。在一些实施方案中，诸如图7所描绘，第一出口通道108a沿着竖直方向6设置，第二出口通道108b被设置成在负水平方向4上与竖直方向6成介于0°和90°之间的角度，并且第三出口通道108c被设置成在与负水平方向相反的正水平方向4上与竖直方向6成介于0°和90°之间的角度。在该描绘的实施方案中，基底200上从出口通道108a、108b和108c分配的三个液滴中的每个液滴之间的距离将与喷嘴100距基底200的距离正相关。
出口通道108在喷嘴100上的具体布置也可确定基底200上的分配图案。应当理解，期望的图案将取决于具体的基底、涂覆用途、被分配的材料、以及其他制造参数，并且本说明书不限于任何具体的分配图案。涂覆器系统10可包括移动机构，该移动机构被构造成使涂覆器系统10和/或喷嘴100以两个、四个或六个运动角度移动。
在一些实施方案中，涂覆器系统10可用于粘结织物材料。例如，涂覆器系统10可将粘合剂材料诸如聚氨酯(PUR)胶的多个液滴分配到织物基底上，该织物基底然后被构造成接收并粘附到其不同部分或单独的织物材料。通过粘结多个织物，可在进行缝合或不进行缝合的情况下组装衣服。
虽然已经结合各个附图的各种实施方案描述了系统和方法，但是本领域的技术人员应当理解，可以在不脱离本发明的广泛发明构思的情况下对实施方案作出改变。因此，应当理解，本公开不限于所公开的具体实施方案，并且旨在涵盖如权利要求书所限定的本公开的实质和范围内的修改。
