Abstract
本发明涉及一种用可流动组分(28)填充筒(16)的方法,该方法包括步骤:提供具有筒室(18)的筒(16),筒具有布置在筒室中的活塞(20),筒室和活塞限定储存容积(30),活塞具有通孔(22);将填充喷嘴(14)布置在通孔处;以及,通过经由活塞(20)的通孔(22)将可流动组分(28)分送到储存容积(30)中来填充筒(16)。本发明还涉及一种适合执行该方法的系统。
Description
技术领域
本发明涉及一种用可流动组分填充筒的方法。该方法能用于填充例如用于工业或牙科部门的筒。
背景技术
筒能够储存各种各样的可流动组分,诸如粘合剂、树脂、硅酮、牙科材料等。如果需要一定量的可流动组分,则组分能通过对筒的活塞施加压力而从筒排出,从而通过筒的出口开口分送组分。
通常,存在用可流动组分填充筒的两种不同的方式。一个选择是所谓的“前填充”,其中,可流动组分通过设置在筒的前侧中的出口开口(其后来用于分送组分)来填充。当通过出口开口填充组分时,活塞通常已被插入筒,并且在填充过程期间从其最前面的位置移动到其最后面的位置。然而,筒通常不设计成前填充的。出口开口的直径常常非常小,导致缓慢的填充过程,这对于高粘性的材料是尤其相关的。另外,由于筒没有被优化以限制空气滞留,所以空气常常被困在筒内。因此,由于前填充缓慢的速度和高的空气滞留风险,所以其常常被摒弃。
用于填充筒的另一选择是“后填充”,其中,活塞尚未被插入筒,并且组分通过筒的后来允许活塞插入的开口并且通过长的喷嘴被填充到筒中。在填充过程期间,喷嘴优选以与填充水平升高相同的速度向上移动(或者筒向下移动)。这对于使可能被困在筒内的空气量最小而言是必需的。一旦期望量的材料已经被填充到筒中,活塞就必须被设定。然而,由于空气可能被困在活塞与组分之间,所以设定活塞可能容易出现错误。此外,当将活塞插入筒时,活塞的密封唇缘可能被损坏。如果活塞由经验不足的人员设定,那么这种情况尤其会变成现实。另外,对于后填充而言,活塞必须与筒分开地运送,这可能导致在运输期间对活塞的损坏。总之,筒的后填充能导致错误或损坏,并且需要对填充过程的高的监测水平。
发明内容
鉴于前述情况,本发明的目的是提供一种用于填充筒的方法,其允许筒的快速填充,并且减少活塞损坏的风险和填充过程中的失效。
这些目的通过根据权利要求1的方法和具有权利要求9的特征的系统来实现。
尤其地,这些目的通过包括以下步骤的方法满足:
提供具有筒室的筒,该筒具有布置在筒室中的活塞,筒室和活塞限定储存容积,活塞具有通孔;
将填充喷嘴布置在通孔处;和
通过经由活塞的通孔将可流动组分分送到储存容积中来填充筒。
换句话说,本发明的方法使用活塞已设定在其中的筒,其中,活塞具有通孔,所述通孔用于经由活塞将可流动组分填充到筒的储存容积中。由于活塞已被设定到筒室中,所以活塞的设定例如能由筒的制造商利用有经验的人员进行。由此,显著减少了损坏例如活塞的密封唇缘的风险。此外,消除了当插入活塞时的空气滞留的风险。
本发明的方法的另一优点是,活塞中的通孔能具有即使当利用高粘性的组分时也允许筒的快速填充的足够大的尺寸或直径。
因此,本发明基于的发现是:如果在筒的填充之前将活塞插入筒室,则能采纳后填充筒的益处(例如,快速的填充过程),只要活塞包括允许经由活塞填充的通孔便可。
筒室可以是筒的内部,即,筒室能由筒的内壁界定。活塞能布置在筒室中,由此,筒室和活塞限定被称为储存容积的大致封闭的容积。贯穿活塞的通孔可以是贯穿活塞的直接通道,其中,优选地,没有活塞的部件延伸到通孔中。
通孔可以形成为管状,具有圆整形状、圆形、矩形或正方形的截面形状,其中,填充喷嘴能至少部分地伸进通孔。填充喷嘴的外部形状能匹配通孔的形状。填充喷嘴可以是分送设备的一部分。
应注意的是,术语“布置在”包含“相邻”、“包括”和“直接连接至”。作为示例,填充喷嘴能(暂时地)直接连接至通孔或布置成与通孔相邻。
优选地,在填充筒之后,能密封通孔。通孔的密封防止当活塞排出可流动组分时可流动组分经由通孔离开。该密封可通过能有利地完全填充通孔的密封塞实现。由此,可从通孔去除通孔中的任何剩余的空气。
有利地,在筒的填充期间,填充喷嘴能伸进通孔。如果填充喷嘴伸进通孔,则将可流动组分分送到活塞或筒的外侧的风险被减小。如果筒的填充是手动进行的,那么这尤其有关系。尤其地,筒能被保持在填充喷嘴下面,由此,可流动组分由于重力而能流过通孔。
优选的是,在筒的填充期间,填充喷嘴被密封地连接至通孔。填充喷嘴与通孔之间的密封连接能防止可流动组分与周围环境的空气、湿气或氧接触。
更优选地,当填充喷嘴被布置在通孔处时,经由通孔分送可流动组分能够被触发。由此,填充能自动开始。尤其地,当密封连接建立时,所述填充能够被触发或开始。
有利地,当经由通孔分送可流动组分时,活塞相对于筒能够被移动,活塞优选通过从可流动组分施加的压力移动。换句话说,利用一定的压力,可流动组分能够被分送到筒中。该压力能使活塞移动,以便允许筒的完全填充。随着活塞相对于筒移动,储存容器增大。
优选的是,在分送可流动组分之前,活塞布置成与筒的出口开口相邻。出口开口可形成筒的远端,其中,出口开口在筒的后来操作中用于分送可流动组分。在筒的填充开始时,活塞因此能布置在筒的远端处,其中,储存容积可以大致为零。随着越来越多的可流动组分流过通孔,活塞朝着筒的近端移动,从而增大储存容积。特别有利的是,由于基本上没有空气于是能滞留在储存容积中,所以活塞初始被布置在筒的远端处。
优选地,当活塞到达预定的位置时,分送可流动组分可以停止。到达预定位置的活塞能指示预定体积的可流动组分已经被填充到筒中。预定位置例如能够是其中活塞与筒的近端齐平的位置,或者其中活塞包括相对于筒的近端的预定距离的位置。替代性地,在经由通孔填充预定体积之后,分送可流动组分可以停止。
有利地,在分送可流动组分已停止之后,可以向填充喷嘴施加低的压力和/或筒能经受振动。利用低的压力,从筒的储存容积吸出剩余的空气。振动能用于即使可流动组分是高度粘性的或者难以流动的,也有利于被困在可流动组分中的小的空气泡能朝着填充喷嘴行进(并通过低的压力从储存容积中被去除)。由此,能进一步使潜在滞留的空气的体积最小。
本发明还涉及一种用可流动组分填充筒的系统,系统包括:
具有筒室的筒,该筒具有布置在筒室中的活塞,筒室和活塞限定储存容积,活塞具有通孔;
分送设备,其具有填充喷嘴,其中,填充喷嘴构造成经由活塞的通孔将可流动组分分送到储存容积中。
该系统能适于执行上述方法。
该系统的筒能够例如用于工业部门,用于建筑工业,以及还用于牙科部门,其中,这样的筒用于储存液体或可流动组分、常常糊状或粘性到高度粘性的物质,并根据需要为相应的应用分送它们。这样的物质的示例是填缝化合物,用于化学销或化学锚的材料、粘合剂、糊剂或牙科部门中的印模材料。筒能够用例如聚丙烯(PP)或聚乙烯(PE)的塑料来生产,并且能够以注射模制过程来制造。筒室可以适于保存体积在100 ml与1000 ml之间、替代性地在400 ml与4000 ml之间的可流动组分。
优选地,填充喷嘴能适应于通孔的形状。填充喷嘴和通孔的形状因此能匹配。尤其地,填充喷嘴的外部轮廓能匹配通孔的内部轮廓。这允许填充喷嘴与通孔之间的密封(即被密封的)连接的形成。为了进一步改善密封功能性,填充喷嘴可以包括柔性或弹性材料,例如合成橡胶。
有利的是,系统还包括用于检测填充喷嘴与通孔之间的密封连接的装置。这些检测装置能在检测到密封连接之后允许填充的自动开始。示例性地,检测能够基于通过使填充喷嘴抵靠到通孔的表面上而闭合的压力开关或电连接。
有利地,活塞可以包括圆柱形状,并且可具有在20 mm与80 mm之间的直径。活塞可具有大约20 mm的高度。优选的是,通孔的面积占去活塞的基本面积的至少5%、优选至少10%、更优选至少25%。至少具有这样的面积的通孔允许对筒的尤其快速的填充。考虑圆形活塞,通孔可具有活塞的直径的一半,由此,通孔的面积占去活塞的基本面积的25%。
通孔的最大面积可以是活塞的基本面积的40%或50%。
通孔的直径可等于或小于20 mm,优选等于或小于15 mm。替代地,通孔可具有近似为活塞的直径的20%至30%的直径。
通孔可布置在活塞的基本面积的中心处。替代地或附加地,通孔可被定位成使得通孔形成活塞的外部边界的一部分。通孔还可包括穿过活塞的两个或更多个分开的通道或孔。
优选地,筒能包括出口开口,出口开口用封闭装置封闭,封闭装置可从出口开口拆除。如上文已经提到的,出口开口在筒后来的“正常”操作期间是分送开口。出口开口在填充期间应封闭,使得可流动的组分不会通过出口开口离开筒。出口开口例如能通过与筒一起制成(例如在一个过程)、优选通过注射模制制成的塞封闭。该塞或封闭盖能通过一部分薄的材料连接至筒,并且在填充之后或者在筒的正常使用之前能被撕开。
有利地,活塞能包括:至少一个密封唇缘,其使活塞与筒室的内壁密封地连接;和/或通气机构,其允许空气从筒室逸出。密封唇缘可具有使可流动组分与周围环境空气、湿气或氧隔绝的轮缘的形式。通气机构可包括迷宫结构,其允许空气在通孔已被密封之后从储存容积中逸出。
在前文中描述的本发明的方法的有利的和优选的特征和实施例同样适用于本发明的系统。
附图说明
在对附图的以下说明中描述本发明的另外的实施例。本发明将在下文中借助于示例性实施例并参考附图被详细说明,在附图中示出的是:
图1是带有筒和分送设备的系统在筒的填充之前的示意图;
图2是图1的系统在筒的填充期间的示意图;和
图3是图1的系统在筒的填充之后的示意图。
具体实施方式
在下文中,相同的附图标记将用于具有相同或等同的功能的零部件。关于组分的方向所作的任何阐述是相对于附图中所示的位置作出,并且当然能在实际应用位置中加以变化。
图1以示意性剖视图示出了系统10。系统10包括带有填充喷嘴14的分送设备12。系统10还包括具有筒室18的筒16。在筒室18内布置有活塞20,活塞20包括通孔22。
图1示出了在空置状态下的筒16,其中,活塞20布置成与出口开口24相邻,出口开口24被注射模制的密封盖26密封。密封盖26由薄的塑料材料制成,并因此能被手动地撕开,以打开出口开口24。
填充喷嘴14具有截头圆锥的形式,并布置成使得其与活塞20的通孔22形成密封连接。当密封连接被分送设备12的检测装置(未示出)检测到时,可流动组分28,例如建筑或牙科材料,从填充喷嘴14被分送到筒16中。
在图2中示出了将可流动组分28分送到筒中。可流动组分28被挤压通过填充喷嘴14并通过通孔22,从而使活塞20向上移动,使得储存容积30在筒室18内膨胀。
在筒16的填充期间,出口开口24以与活塞20从出口开口24移开相同的方式从分送设备12的填充喷嘴14移开。
在图3中示出了筒被完全填满可流动组分28的状态。在完全填满的状态下,储存容积30大致等于筒室18的容积。在该状态下,填充喷嘴14与通孔22之间的密封连接能终止。通孔22于是可以用密封塞32封闭,使得可流动组分28能长时间储存在筒16内。
