本发明还涉及用于填充分配模块的方法。The invention also relates to a method for filling a dispensing module.
本申请中的术语“液体产品”指的是可以通过分配模块输出的所有产品，即，也包括高度粘稠或气态的产品以及分散于气体中的固体。The term "liquid product" in this application refers to all products that can be delivered through a dispensing module, ie also highly viscous or gaseous products and solids dispersed in a gas.
经常需要将一个容器中所含的两种产品分离，直到它们使用时，以便例如避免产品之间的不希望的化学反应。在这些情况下，将两种产品保持在容器的彼此分开的两个腔中，并通过两路阀或两路泵输送至分配孔，在此它们彼此发生接触。It is often necessary to separate two products contained in one container until their use, for example to avoid undesired chemical reactions between the products. In these cases, the two products are kept in two chambers of the container separated from each other and delivered by means of a two-way valve or a two-way pump to the dispensing orifice where they come into contact with each other.
双活塞系统也是已知的。DE202007004662U1公开了具有两个活塞的容器，所述两个活塞布置成一个在另一个之上并且沿着容器的壁滑动。将两路泵设置在容器上。泵的第一路在容器的顶端向外开放。第二路在横穿第一活塞的线中向外开放，并且第一活塞可以沿着其滑动。第一产品位于第一活塞以上的空间中，而第二产品位于第一和第二活塞之间的空间中。将两种产品以不够精确的混合比输送的风险在所述设备的情况下也相对较大。Dual piston systems are also known. DE 20 2007 004 662 U1 discloses a container with two pistons arranged one above the other and sliding along the wall of the container. Set the two-way pump on the container. The first way of the pump opens out at the top of the container. The second way opens outwards in a line traversing the first piston and along which the first piston can slide. The first product is located in the space above the first piston and the second product is located in the space between the first and second pistons. The risk of conveying the two products in an imprecise mixing ratio is also relatively great in the case of this device.
所述缺点以下述方式避免：将两个活塞以机械方式耦接在一起，以使得当一个活塞移位时，另一个活塞也以相应的方式移位。该方案来自于文献US3,915,345A或DE2007199A。在两种情况下，存在固定于两路阀的中心圆筒。所述两路阀固定于也为圆筒形的外套上。第一活塞沿着中心圆筒的内壁滑动，从而形成第一腔，而第二圆环形活塞通过其中心边缘沿着中心圆筒的外壁并通过其外边缘沿着外套的壁滑动，从而形成第二腔。两个活塞连接在一起。在文献US3,915,345A的情况下，它们通过围绕着中心圆筒的底部边缘的双重壁连接。在DE2007199A的第一种示例性实施方案中，两个活塞通过圆环状空间分离并通过它们的底端由基板连接。两个活塞的共同移位所需的推进剂位于基板之下或者活塞之下。Said disadvantages are avoided in that the two pistons are mechanically coupled together such that when one piston is displaced, the other piston is also displaced in a corresponding manner. This scheme comes from literature US3,915,345A or DE2007199A. In both cases there is a central cylinder fixed to the two-way valve. Said two-way valve is fixed on a casing which is also cylindrical. The first piston slides along the inner wall of the central cylinder, thereby forming the first cavity, while the second annular piston slides by its central edge along the outer wall of the central cylinder and by its outer edge along the wall of the outer casing, thereby forming second chamber. The two pistons are connected together. In the case of document US 3,915,345A, they are connected by a double wall surrounding the bottom edge of the central cylinder. In a first exemplary embodiment of DE2007199A, two pistons are separated by an annular space and connected by their bottom ends by a base plate. The propellant required for the joint displacement of the two pistons is located under the base plate or under the pistons.
在两种情况下，两个腔的填充均导致问题。由于考虑到输入孔的尺寸而不可能同时填充两个腔，需要首先填充一个腔，然后填充另一个。然而，由于两个活塞以机械方式连接在一起，当一个腔被填充时，布置于其中的活塞被向下挤压并带动另一个活塞。第二腔形成，并被空气填充。结果，已进入第二腔的空气必须在用产品填充第二腔之前去除。In both cases the filling of both cavities caused problems. Since it is not possible to fill both cavities at the same time due to the size of the input hole, one needs to be filled first and then the other. However, since the two pistons are mechanically linked together, when one cavity is filled, the piston disposed therein is pressed down and brings the other piston along. A second cavity is formed and filled with air. As a result, air that has entered the second chamber must be removed before filling the second chamber with product.
因此，本发明的目标是创造在前文中所述的更容易填充的分配模块，并创造用于填充所述分配模块的方法。It is therefore an object of the present invention to create an easier to fill dispensing module as described above and to create a method for filling said dispensing module.
所述目标通过如下方式实现：第二壁通过外套形成，分配模块能够被插入所述外套中，其中第二活塞和第二壁形成具有至少一个出口孔的第二腔。This object is achieved in that the second wall is formed by a casing into which the dispensing module can be inserted, wherein the second piston and the second wall form a second chamber with at least one outlet opening.
第一和第二壁优选是圆筒形的，然而也可以考虑其他方案，例如具有椭圆截面的壁。The first and second walls are preferably cylindrical, however other solutions are also conceivable, eg walls with an elliptical cross-section.
填充用于两种液体的这种分配模块的问题是通过初始地解耦直到填充操作过程中才耦接在一起的两个活塞来解决。首先填充的腔的活塞的下降不会导致还未耦接的活塞头也下降。一旦第二液体填充进去，第二活塞头就下降并耦接至耦接装置。The problem of filling such a dispensing module for two liquids is solved by initially decoupling the two pistons which are not coupled together until during the filling operation. The lowering of the piston of the first filled chamber does not lead to lowering of the not yet coupled piston head. Once the second liquid is filled in, the second piston head is lowered and coupled to the coupling device.
在本发明中要求保护的是，第二壁是分配模块的整体组件，第二活塞和第二壁形成具有至少一个出口孔的第二腔。因此，第二腔是分配模块的整体组件。What is claimed in the present invention is that the second wall is an integral component of the dispensing module, the second piston and the second wall forming a second chamber with at least one outlet orifice. Thus, the second chamber is an integral component of the distribution module.
作为这一点的替代，也可能第二壁由外套形成，分配模块能够被插入所述外套中，其中第二活塞和第二壁形成具有至少一个出口孔的第二腔。As an alternative to this, it is also possible that the second wall is formed by a casing into which the dispensing module can be inserted, wherein the second piston and the second wall form a second chamber with at least one outlet opening.
与本发明相关的是在耦接装置中提供至少一个压力平衡孔，以便将在出口孔的操作状态中与各自腔背离的一个或多个活塞头的侧面与在出口孔的操作状态中与各自腔相对地存在的其它活塞的侧面连接。Relevant to the invention is the provision of at least one pressure equalization hole in the coupling device in order to connect one or more sides of the piston head facing away from the respective cavity in the operating state of the outlet hole to the respective chamber in the operating state of the outlet hole. The cavity is connected to the side of the other piston that exists opposite.
所述压力平衡孔避免当将第一液体填充到分配模块中时形成真空。The pressure equalization hole avoids the formation of a vacuum when filling the first liquid into the dispensing module.
在本发明的框架内，提供连接至腔的出口孔的去除装置。Within the framework of the invention, removal means connected to the outlet orifice of the chamber are provided.
在该情况下，有利的是，去除装置包括两路阀或两路泵，其中第一路连接至第一腔的出口孔并且第二路连接至第二腔的出口孔。In this case, it is advantageous if the removal means comprise a two-way valve or a two-way pump, wherein a first way is connected to the outlet orifice of the first chamber and a second way is connected to the outlet orifice of the second chamber.
本发明的一种方案在于去除装置包括计量设备。One variant of the invention consists in that the removal device comprises a metering device.
还便利的是，提供关闭装置以便关闭第一腔和第二腔的出口孔，其中关闭装置具有开启和关闭位置。It is also convenient that closure means are provided for closing the outlet apertures of the first and second chambers, wherein the closure means has an open and a closed position.
在本发明的另一种方案的情况下，配备活塞头的腔的尺寸使得在第一活塞在出口孔方向上以最大方式插入第一腔中的情况下，在填充就绪状态下对于未连接至耦接装置的活塞头仍然存在足够的空间。In the case of another solution of the invention, the size of the chamber equipped with the piston head is such that, with the first piston inserted into the first chamber at its maximum in the direction of the outlet opening, in the ready-to-fill state for There is still sufficient space for the piston head of the coupling.
在本发明的框架内，还存在用于填充本发明要求保护的分配模块的方法，该方法具有下列方法步骤：Within the framework of the invention there is also a method for filling the distribution module claimed in the invention, which method has the following method steps:
a1）组装分配模块以使得第一活塞位于与第一腔的一个或多个出口孔最近的位置，其中一个或多个活塞头未连接至耦接装置；a1) Assembling the dispensing module such that the first piston is located proximate to the one or more outlet holes of the first chamber, wherein the one or more piston heads are not connected to the coupling means;
b1）如果需要，在分配模块还不具有第二圆筒形壁的情况下，将分配模块插入外套中以形成第二腔；b1) inserting the distribution module into the housing to form a second chamber, if required, if the distribution module does not yet have a second cylindrical wall;
c1）将第一液体填充到未配备活塞头的腔中，或者选择性地填充到两个腔之一中，如果两个腔均配备了活塞头；c1) filling of the first liquid into the chamber not equipped with a piston head, or optionally into one of the two chambers, if both chambers are equipped with a piston head;
d1）将第二液体在足够的压力下填充到配备活塞头的仍然空的腔中，以便在填充操作结束时将活塞头连接至耦接装置。d1) Filling the still empty chamber equipped with the piston head with the second liquid under sufficient pressure to connect the piston head to the coupling device at the end of the filling operation.
本发明的一种方案在于，在步骤c1）之前，在步骤c0i）中将去除装置或关闭装置应用至两个腔的出口孔。One solution of the invention consists in applying removal means or closing means to the outlet openings of the two chambers in step c0i) prior to step c1).
本发明的另一种方案在于，在步骤c1）之前，在步骤c0ii）中将分配模块引入容器内部，该容器的内壁不充当第二腔的壁。Another variant of the invention consists in that, prior to step c1), in step c0ii), the dispensing module is introduced into the interior of a container whose inner wall does not serve as a wall of the second chamber.
在本发明中要求保护的是，在步骤c1）之前，在步骤c0iii）中将压缩气体引入外套中。What is claimed in the present invention is that compressed gas is introduced into the jacket in a step c0iii) before step c1).
作为这一点的替代，也可以在步骤d1）后，在步骤e1）中将压缩气体引入外套中。As an alternative to this, compressed gas can also be introduced into the jacket in step e1) after step d1).

示出的分配模块（1）配备有两个腔（20，30），所述分配模块固定于容器（5）的阀（4），所述容器优选为压力容器。每个腔（20，30）配备有活塞（61、64和7）。提供耦接装置（62），以便一旦腔已被填充就将两个活塞（61、64和7）耦接在一起，以使得它们同时移动。阀（4）优选是两路阀，以使得第一腔（30）中所含的产品不与来自第二腔（20）的产品发生接触，直到从阀（4）排出或者可能地直到从固定于阀（4）的出口孔排出。The dispensing module ( 1 ) shown is equipped with two chambers ( 20 , 30 ), said dispensing module being fixed to a valve ( 4 ) of a container ( 5 ), preferably a pressure container. Each chamber (20, 30) is equipped with a piston (61, 64 and 7). Coupling means (62) are provided to couple the two pistons (61, 64 and 7) together once the cavity has been filled so that they move simultaneously. The valve (4) is preferably a two-way valve so that the product contained in the first chamber (30) does not come into contact with the product from the second chamber (20) until drained from the valve (4) or possibly until from a fixed It is discharged from the outlet hole of valve (4).
分配模块（1）基本上由内壳（3）、外壳（2）、耦接装置（62）和保持装置（8）组成，其中在内壳中第一活塞（64）滑动并形成第一腔（30），在外壳的底部区域（21）第二活塞（61）滑动并形成第二腔（20），耦接装置用于将两个活塞（61、64和7）耦接在一起，保持装置用于充当第二活塞（61）的止动件。The dispensing module (1) essentially consists of an inner housing (3), an outer housing (2), a coupling device (62) and a holding device (8), wherein in the inner housing a first piston (64) slides and forms a first chamber (30), in the bottom area of the housing (21) the second piston (61) slides and forms the second cavity (20), the coupling device is used to couple the two pistons (61, 64 and 7) together, hold The device is used to act as a stop for the second piston (61).
外壳（2）由底部的第一圆筒形部分（21）和具有较小直径的顶部的第二圆筒形部分（22）组成。两个圆筒形部分通过径向连接壁（23）连接在一起。在所示的示例性实施方案中，顶部圆筒形部分（22）的壁通过穿过径向壁（23）而略微穿入第一圆筒形部分（21）的顶部中。突起（25）充当第二活塞（61）的顶部止动件。然而，还可能省略所述突起并使用径向壁作为止动件。顶部圆筒形部分（22）在其顶部区域具有环形径向肩（26），其被一个或多个孔（261）穿过。以这种方式实现了在两端有孔的情况下以管状方式形成外壳。将沟道（24）设置在顶部圆筒形部分（22）的内侧表面。它们在所述顶部部分（22）的整个高度上延伸。第二圆筒形部分（22）的顶部表面配备有紧固装置（27），由此将两腔分配模块（1）固定至两路阀（4）。所述紧固装置（27）包括冠状件，其配备有插销装置，该插销装置可以与两路阀（4）上的互补插销装置相互作用。The housing (2) consists of a first cylindrical part (21) at the bottom and a second cylindrical part (22) at the top with a smaller diameter. The two cylindrical parts are connected together by radial connecting walls (23). In the exemplary embodiment shown, the wall of the top cylindrical portion ( 22 ) penetrates slightly into the top of the first cylindrical portion ( 21 ) by passing through the radial wall ( 23 ). The protrusion (25) acts as a top stop for the second piston (61). However, it is also possible to omit said protrusions and use radial walls as stops. The top cylindrical portion (22) has an annular radial shoulder (26) in its top region, which is penetrated by one or more holes (261). In this way it is achieved that the casing is formed in a tubular manner with holes at both ends. A channel (24) is provided on the inside surface of the top cylindrical portion (22). They extend over the entire height of said top part ( 22 ). The top surface of the second cylindrical part ( 22 ) is equipped with fastening means ( 27 ), whereby the two-chamber dispensing module ( 1 ) is fixed to the two-way valve ( 4 ). Said fastening means ( 27 ) comprise a crown equipped with a latch that can interact with a complementary latch on the two-way valve ( 4 ).
内壳（3）基本上由圆筒形主要部分（31）组成，该圆筒形主要部分的外侧直径基本上对应于外壳（2）的顶部圆筒形部分（22）的内侧直径。圆筒形主要部分（31）在其顶部区域呈锥形，优选通过形成截头锥形壁（32）而实现，并用形成套筒（33）的圆筒形部分封闭。正像外壳（2）一样，内壳也具有在两端均形成有孔的管状形式。套筒（33）具有环形径向凹槽（331），其向外侧开放并且其底部直径和高度对应于外壳（2）的顶部圆筒形部分（22）的环形肩（26）的内侧直径和高度。因此，内壳（3）可以插入外壳（2）的顶部圆筒形壁（22）的内部，直到套筒（33）啮合到环形肩（26）中央的孔中并且所述肩（26）啮合到凹槽（331）中。以这种方式，将内壳（3）以固定方式紧固在外壳（2）的内部。选择内壳（3）的长度以使得底端在锁入外壳（2）中的位置与外壳（2）的顶部圆筒形部分（22）的底端对齐。通过沟道（24），内壳（3）用于限定第二腔（20）中所含的产品的出口线。为此目的，沟道（24）的尺寸使得它们开放到在截头锥形壁（32）以上但是在环形肩（26）以下的空间中。The inner shell (3) essentially consists of a cylindrical main part (31) whose outer diameter substantially corresponds to the inner diameter of the top cylindrical part (22) of the outer shell (2). The cylindrical main part (31) is tapered in its top region, preferably by forming a frusto-conical wall (32), and is closed with a cylindrical part forming a sleeve (33). Just like the outer shell (2), the inner shell also has a tubular form with holes formed at both ends. The sleeve (33) has an annular radial groove (331) which is open to the outside and whose bottom diameter and height correspond to the inner diameter and high. Thus, the inner shell (3) can be inserted inside the top cylindrical wall (22) of the outer shell (2) until the sleeve (33) engages in the hole in the center of the annular shoulder (26) and said shoulder (26) into the groove (331). In this way, the inner shell (3) is fastened inside the outer shell (2) in a fixed manner. The length of the inner shell (3) is chosen so that the bottom end in position to lock into the outer shell (2) is aligned with the bottom end of the top cylindrical portion (22) of the shell (2). Through the channel (24), the inner shell (3) serves to define an outlet line for the product contained in the second chamber (20). For this purpose, the channels ( 24 ) are dimensioned such that they open into the space above the frustoconical wall ( 32 ) but below the annular shoulder ( 26 ).
将两个活塞结合在一个活塞单元（6）中。第二活塞（61）具有固定至圆筒形部分（62）的底端的径向环形部分。在其边缘，径向环形部分具有轴向边沿（63），该轴向边沿从环形部分的背离圆筒形部分（62）的一侧起延伸。所述边沿（63）的外侧直径对应于外壳的底部部分（21）的内侧直径。边沿（63）配备有密封装置，以便将活塞（61）密封于外壳（2）的底部部分（21）的内侧表面。所述密封装置例如形成为滑动凝胶或密封唇（631）形式的不流动、高粘度密封装置，所述密封装置由例如弹性体材料组成。活塞单元（6）的圆筒形部分（62）的外侧直径基本上对应于内壳（3）的内侧直径。Combine two pistons in one piston unit (6). The second piston (61) has a radial annular portion fixed to the bottom end of the cylindrical portion (62). At its edge, the radial annular portion has an axial rim ( 63 ) extending from the side of the annular portion facing away from the cylindrical portion ( 62 ). The outer diameter of said rim (63) corresponds to the inner diameter of the bottom part (21) of the casing. The rim (63) is equipped with sealing means to seal the piston (61) to the inside surface of the bottom part (21) of the casing (2). The sealing means is formed, for example, as a non-flowing, high-viscosity sealing means in the form of a sliding gel or a sealing lip ( 631 ), consisting of eg an elastomeric material. The outside diameter of the cylindrical part (62) of the piston unit (6) substantially corresponds to the inside diameter of the inner housing (3).
以这种方式，第二腔（20）通过环形空间形成，所述环形空间一方面在外壳的圆筒形底部部分（21）和活塞单元（6）的圆筒形部分之间，另一方面在将底部部分（21）和顶部部分（22）连接在一起的外壳的径向壁（23）和第二活塞（61）之间。In this way, the second chamber (20) is formed by an annular space between the cylindrical bottom part (21) of the housing and the cylindrical part of the piston unit (6) on the one hand and Between the radial wall (23) of the housing connecting the bottom part (21) and the top part (22) together and the second piston (61).
第二活塞（61）可以在外壳（2）的底部圆筒形部分（21）的内部滑动。为了防止它从其中脱离，一旦分配模块（1）的所有部分已插入外壳（2），就将其保持装置（8）固定于底端。所述保持装置（8）形成为轴向边沿（81），其内侧直径基本上对应于外壳的底部圆筒形部分（21）的外侧直径。所述轴向边沿（81）在其底部区域越过环形径向壁（82）向中心延伸。将保持装置（8）固定于外壳（2）的底部部分（21）的底端，例如通过插销装置。活塞（61）因此可以在第一位置和第二位置之间移位，在第一位置中它抵靠外壳（2）的径向壁（23）（见图3），在第二位置中其底部边沿（63）抵靠保持装置（8）的环形壁（82）（见图4）。The second piston (61) can slide inside the bottom cylindrical part (21) of the housing (2). In order to prevent it from coming out of it, once all parts of the dispensing module (1) have been inserted into the housing (2), its retaining means (8) are fixed at the bottom end. Said retaining means (8) is formed as an axial rim (81) whose inside diameter substantially corresponds to the outside diameter of the bottom cylindrical part (21) of the housing. Said axial rim (81) extends in its bottom region towards the center beyond the annular radial wall (82). The retaining means (8) are secured to the bottom end of the bottom part (21) of the housing (2), for example by means of a latch. The piston (61) is thus displaceable between a first position, in which it abuts against the radial wall (23) of the housing (2) (see Figure 3), and a second position, in which it The bottom edge ( 63 ) bears against the annular wall ( 82 ) of the holding device ( 8 ) (see FIG. 4 ).
第一活塞（64）通过活塞单元（6）的圆筒形部分（62）的顶部表面（64）形成。所述圆筒形部分（62）因此充当耦接装置，它使得可以同时移动两个活塞（61、64）。The first piston (64) is formed by the top surface (64) of the cylindrical portion (62) of the piston unit (6). Said cylindrical portion ( 62 ) thus acts as a coupling device which makes it possible to move both pistons ( 61 , 64 ) simultaneously.
将单独的活塞头（7）固定至第一活塞（64）的顶部表面。所述活塞头（7）基本上由径向圆形壁（71）形成，该圆形壁通过边沿（72）向下伸长。在边沿的外表面上以密封唇（721）的形式提供密封装置。边沿（72）的外侧直径对应于内壳（3）的圆筒形主要部分（31）的内侧直径。A separate piston head (7) is secured to the top surface of the first piston (64). Said piston head (7) is substantially formed by a radial circular wall (71) which is elongated downwards by a rim (72). A seal is provided in the form of a sealing lip (721) on the outer surface of the rim. The outer diameter of the rim ( 72 ) corresponds to the inner diameter of the cylindrical main part ( 31 ) of the inner shell ( 3 ).
因此，第一腔（30）通过一方面内壳（3）的内表面与另一方面其顶部表面（32）和活塞头（7）之间的空间限定。活塞头（7）也充当第二腔（20）的顶部部分的密封环。Thus, the first chamber ( 30 ) is delimited by the space between the inner surface of the inner housing ( 3 ) on the one hand and its top surface ( 32 ) and the piston head ( 7 ) on the other hand. The piston head (7) also acts as a sealing ring for the top part of the second chamber (20).
活塞头（7）配备有插销装置（722），它使得可以将其以不可逆的方式锁定于设置在活塞单元（6）的顶部表面上的互补插销装置（641）。所述插销装置（641、722）的尺寸使得足够强的压力必须施加于活塞头（7）上以使得它锁定于活塞（64）的顶部表面上，并且以优选的方式配备一个或多个格栅元件，它能够弥补可能的填充容限。以这种方式，避免了不希望的啮合，特别是在储存过程中或者当操纵空的分配模块时。此外，选择内壳的圆筒形主要部分（31）的高度（并因此选择外壳的顶部部分（22）的高度）以使得当活塞单元（6）位于顶部位置时（其中第二活塞（61）抵靠径向连接壁（23）），对于圆筒形部分（62）和释放的、未啮合的活塞头（7）而言，在内壳的内部存在足够的空间。The piston head ( 7 ) is equipped with latch means ( 722 ) which make it possible to lock it irreversibly to complementary latch means ( 641 ) provided on the top surface of the piston unit ( 6 ). Said latch means (641, 722) are dimensioned such that sufficient pressure must be exerted on the piston head (7) to lock it onto the top surface of the piston (64), and are preferably provided with one or more lattice gate element, which compensates for possible filling tolerances. In this way, undesired engagement is avoided, in particular during storage or when handling empty dispensing modules. Furthermore, the height of the cylindrical main part (31) of the inner housing (and thus the height of the top part (22) of the outer housing) is chosen such that when the piston unit (6) is in the top position (where the second piston (61) Against the radial connecting wall ( 23 )), there is sufficient space inside the inner housing for the cylindrical part ( 62 ) and the released, unengaged piston head ( 7 ).
当组装时，首先将内壳固定于外壳中，将活塞头（7）插入内壳（3）的内部，然后将活塞单元（6）插入，它被插入地尽可能远，即，直到第二活塞（61）抵靠连接壁（23）。在该位置，活塞头（7）位于活塞单元（6）的顶部部分上方，但未锁定于其中。两个活塞（61、64）的密封装置（631、721）在各自的腔的内壁上施加足够的压力，以便将活塞单元（6）和活塞头（7）保持在它们的位置，只要没有产品被填充进去。When assembling, the inner shell is first fixed in the outer shell, the piston head (7) is inserted inside the inner shell (3), and then the piston unit (6) is inserted, which is inserted as far as possible, i.e., up to the second The piston (61) abuts against the connecting wall (23). In this position, the piston head (7) is above the top part of the piston unit (6), but not locked therein. The seals (631, 721) of the two pistons (61, 64) exert sufficient pressure on the inner walls of the respective chambers to hold the piston unit (6) and the piston head (7) in their position as long as there is no product is filled in.
具有两个腔的这种单元拟用于固定于分配装置上，例如两路阀（4）或两路泵。也可以仅提供关闭装置，它在分配操作过程中开启。分配装置可以包括计量装置，使得当分配装置被驱动时，输出预定量的每种产品。两路阀是已知的，例如来自文献US3,915,345或WO2007/132017A1。在此处所示的实例中，这是后一文献中所记载的类型的两路阀。所述阀的操作方法因此不再详细记载。This unit with two chambers is intended to be fixed on a dispensing device, such as a two-way valve (4) or a two-way pump. It is also possible to provide only closing means, which are opened during the dispensing operation. The dispensing device may comprise metering means such that when the dispensing device is actuated, a predetermined amount of each product is delivered. Two-way valves are known, for example from documents US 3,915,345 or WO 2007/132017 A1. In the example shown here, this is a two-way valve of the type described in the latter document. The method of operation of the valve is therefore not described in detail.
和文献WO2007/132017A1的两路阀的情况一样，可以在阀（41）的本体中提供一个或多个孔，使得气体可以沿着与阀被驱动时产品的路径相同的路径从第二腔（20）逸出。可以为推进剂提供它不与之反应的第三产品。那么容器含有在储存过程中在空间上分离的三种产品。As in the case of the two-way valve of document WO2007/132017A1, one or more holes can be provided in the body of the valve (41) so that gas can flow from the second chamber ( 20) escape. The propellant may be provided with a third product with which it does not react. The container then contains three products that are spatially separated during storage.
由两腔分配模块（1）和分配装置（4）组成的单元因而可以固定在外套（5）中。如果分配单元（1）的尺寸允许，特别是如果外壳（2）的外侧直径和/或分配装置的阀盘（44）的直径的尺寸允许，分配模块（1）可以插入预先制造的外套的内部区域。否则，需要围绕着分配模块（1）形成外套（5）。这是图中所示的实施例的情况。The unit consisting of the two-chamber distribution module ( 1 ) and the distribution device ( 4 ) can thus be fixed in the casing ( 5 ). If the dimensions of the dispensing unit (1) permit, in particular if the dimensions of the outside diameter of the housing (2) and/or the diameter of the valve disc (44) of the dispensing device allow, the dispensing module (1) can be inserted inside a prefabricated housing area. Otherwise, a jacket (5) needs to be formed around the distribution module (1). This is the case for the embodiment shown in the figure.
第一和第二产品的初始体积之比通过第一活塞（64）和第二活塞（61）的面积之比确定。分配模块因此实现非常高水平的精度，这是两种产品的初始体积之比所需的。作为第一活塞（61）和第二活塞（64）的面积之间的面积比的结果，也可以在比外部压力更高的压力下填充第二腔（30）。The ratio of the initial volumes of the first and second products is determined by the ratio of the areas of the first piston (64) and the second piston (61). The dispensing module thus achieves a very high level of precision, which is required for the ratio of the initial volumes of the two products. As a result of the area ratio between the areas of the first piston ( 61 ) and the second piston ( 64 ), it is also possible to fill the second chamber ( 30 ) at a higher pressure than the external pressure.
明显的是，第二活塞（61）也可以由单独的活塞头形成。活塞头因而是环形的。活塞单元的圆筒形部分（62）和/或外壳的底部圆筒形部分（21）的高度必须足够大，以便使得活塞单元能够完全穿入内壳中，所述活塞单元通过其顶部部分抵靠，其中环形活塞头没有锁定于活塞单元（6）中。如果第二活塞（61）具有单独的活塞头，不需要为第一活塞（64）也提供单独的活塞头（7）。It is obvious that the second piston ( 61 ) can also be formed by a separate piston head. The piston head is thus annular. The height of the cylindrical part (62) of the piston unit and/or the bottom cylindrical part (21) of the outer casing must be large enough to allow the piston unit to penetrate completely into the inner casing, said piston unit resting with its top part , where the annular piston head is not locked in the piston unit (6). If the second piston ( 61 ) has a separate piston head, it is not necessary to also provide a separate piston head ( 7 ) for the first piston ( 64 ).
如果分配模块（1）用于压力容器上，如在此所示的实施例中一样，那么可以将包含分配单元（1）和分配装置（4）的单元布置在外套（5）中的稳固位置，阀盘（44）还没有连接至外套（85）。这使得可以在填充过程中在阀盘（44）固定于外套（5）上之前填充推进剂。为了将包含分配模块/分配装置的单元固定在所述位置（如图2中所示），提供叉（9），它阻挡该单元以使得外壳的第二圆筒形部分（22）的尖端抵靠外套（5）的顶部表面的内表面。所述可去除的叉（9）穿入凹槽（28）中，所述凹槽为此目的在紧固装置（27）以下在外壳（2）的尖端处提供。If the dispensing module (1) is used on a pressure vessel, as in the embodiment shown here, the unit containing the dispensing unit (1) and the dispensing device (4) can be arranged in a stable position in the housing (5) , the valve disc (44) is not yet connected to the housing (85). This makes it possible to fill the propellant during the filling process before the valve disc ( 44 ) is fixed on the casing ( 5 ). In order to fix the unit containing the dispensing module/dispensing device in said position (as shown in Figure 2), a fork (9) is provided, which blocks the unit so that the tip of the second cylindrical part (22) of the housing rests against the The inner surface against the top surface of the jacket (5). Said removable prongs ( 9 ) penetrate into grooves ( 28 ) provided for this purpose at the tip of the casing ( 2 ) below the fastening means ( 27 ).
可去除的活塞头的原理也可以是诸如DE2007199A或US3,915,345A中所述的装置的情况。在这种情况下，分配模块（1）仅由一个第一腔（30）、一个第二活塞（61）和耦接装置（62）组成，其中第一活塞（64和7）在第一腔中滑动。第二腔形成的壁不与分配模块关联。它例如由外套（5）的内壁组成。同样，在该情况下，活塞头可以选择性地用于第一腔或者还未形成的第二腔。The principle of a removable piston head may also be the case for devices such as those described in DE2007199A or US3,915,345A. In this case, the dispensing module (1) consists only of a first chamber (30), a second piston (61) and coupling means (62), where the first pistons (64 and 7) Swipe in. The walls formed by the second chamber are not associated with the distribution module. It consists, for example, of the inner wall of the jacket ( 5 ). Also in this case, the piston head can be selectively used for the first cavity or the not yet formed second cavity.
本发明要求保护的分配模块的填充参照图3、4、5和6进行说明。The filling of the distribution module as claimed in the invention is explained with reference to FIGS. 3 , 4 , 5 and 6 .
图3示出配备有固定至两路阀（4）的分配模块（1）的容器，该两路阀（4）固定于外套（5）的颈上。气体已被引入外套中并在第一活塞（64）的活塞头（7）和第二活塞（61）两者上施加压力。该容器现在可以用两种产品填充。为此，首先通过分配装置（4）的第二路，然后通过沟道（24），将第一产品填充到不具有单独的活塞头的第二腔（20）中。活塞单元（6）被压在第二活塞（61）上的进入产品推回。单独的活塞头（7）保持在其初始位置，即，第一腔（30）的顶部区域，而活塞单元（6）的顶部部分被第二活塞（61）向下推。活塞单元的顶部部分（64）的压力平衡孔（642）防止在固定的活塞头（7）和向下移动的顶部部分之间形成真空。在第二腔（20）的填充操作结束时，第二活塞（61）的边沿（63）抵靠保持装置（8）的环形径向壁（82），如图4中所示。Figure 3 shows a container equipped with a dispensing module (1 ) secured to a two-way valve (4) secured to the neck of the casing (5). Gas has been introduced into the casing and exerts pressure on both the piston head (7) of the first piston (64) and the second piston (61). The container can now be filled with two products. To this end, the first product is filled into the second chamber ( 20 ) which does not have a separate piston head, first through the second path of the dispensing device ( 4 ) and then through the channel ( 24 ). The piston unit (6) is pushed back by the incoming product pressing on the second piston (61). The individual piston head (7) remains in its initial position, ie the top area of the first chamber (30), while the top part of the piston unit (6) is pushed down by the second piston (61). A pressure equalization hole (642) in the top part (64) of the piston unit prevents the formation of a vacuum between the stationary piston head (7) and the downwardly moving top part. At the end of the filling operation of the second chamber ( 20 ), the rim ( 63 ) of the second piston ( 61 ) abuts against the annular radial wall ( 82 ) of the holding device ( 8 ), as shown in FIG. 4 .
然后第二产品可以通过阀（4）的第一路、龙头（43）和套筒（33）填充到第一腔（30）中。进入产品向下挤压活塞头（7）。在活塞单元的圆筒形部分（62）内部之间的空间中的气体通过压力平衡孔（642）在活塞单元的顶部部分中被挤出。由第二产品施加于活塞头（7）上的压力足够，以便克服插销装置（641、722）的阻力并将活塞头（7）锁定在活塞单元（6）中。两个活塞（61、64）从而耦接在一起，并可以同时移动。这对应于图5中所示的情形。喷雾头仍然必须安装就位于阀的杆（45）上，以及可能的安装于其上的保护帽。容器已可以使用。由于单独的活塞头（7），可以在两个独立的填充单元填充容器，而不需要在填充第一腔之前将空气吸出，这在现有技术的两腔设备的情况下是需要的。Then the second product can be filled into the first chamber (30) through the first way of the valve (4), tap (43) and sleeve (33). The entry product squeezes the piston head (7) downwards. The gas in the space between the inside of the cylindrical part (62) of the piston unit is squeezed out in the top part of the piston unit through the pressure balance hole (642). The pressure exerted by the second product on the piston head (7) is sufficient to overcome the resistance of the latch means (641, 722) and lock the piston head (7) in the piston unit (6). The two pistons (61, 64) are thus coupled together and can move simultaneously. This corresponds to the situation shown in FIG. 5 . The spray head must still be mounted on the stem (45) of the valve, and possibly the protective cap mounted on it. The container is ready to use. Thanks to the separate piston head (7), it is possible to fill the container in two separate filling units without the need to suck the air out before filling the first chamber, which is required in the case of prior art two-chamber devices.
该方法因此可以总结为以下步骤：The method can thus be summarized in the following steps:
a1）准备分配模块，活塞单元定位为尽可能接近第一腔（30）的一个或多个出口孔。这保证活塞头（7）从耦接装置（62）脱离。分配模块（1）位于图3中所示的状态，去除装置（4）和外套（5）被省略。a1) Prepare the dispensing module, the piston unit is positioned as close as possible to the one or more outlet holes of the first chamber (30). This ensures that the piston head (7) is disengaged from the coupling device (62). The dispensing module (1) is in the state shown in Fig. 3, the removal device (4) and the casing (5) are omitted.
b1）如果分配模块（1）和在上述情况下一样不具有第二腔，它必须被插入到充当第二腔的外壁的圆筒形壁中。圆筒形壁可以和US3,915,345A或DE2007199A中一样通过容器的外套形成。b1) If the dispensing module ( 1 ) does not have a second chamber as in the above case, it has to be inserted into the cylindrical wall which acts as the outer wall of the second chamber. The cylindrical wall can be formed by the jacket of the container as in US 3,915,345A or DE2007199A.
c0i）如果液体将通过去除装置去除，例如两路阀（4）或两路泵或者腔的出口孔简单地通过塞子关闭，那么可以在填充液体之前安装所述去除装置或者关闭装置。c0i) If the liquid is to be removed by a removal device such as a two-way valve (4) or a two-way pump or the outlet hole of the chamber is simply closed by a plug, then said removal device or closing device can be installed before filling the liquid.
c0ii）如果分配模块设置在容器内部，其内壁不充当第二腔的壁，那么这应当优选在填充液体之前进行。c0ii) If the dispensing module is arranged inside a container whose inner wall does not serve as a wall of the second chamber, then this should preferably be done before filling with liquid.
c0iii）如果容器将被加压，可以在从步骤b0）或c0ii）起将分配模块或去除装置连接至容器之前在容器中填充气体。c0iii) If the container is to be pressurized, it is possible to fill the container with gas before connecting the dispensing module or removal device to the container from step b0) or c0ii).
c1）将第一液体填充到第二腔（20）中。如果活塞头不设置在第一腔中而是设置在第二腔中，那么首先填充第一腔。如果将活塞头设置于两个腔中，可以从第一或第二腔中的任一个开始。c1) Filling the first liquid into the second chamber (20). If the piston head is not arranged in the first chamber but in the second chamber, the first chamber is filled first. If the piston head is provided in two chambers, it can start with either the first or second chamber.
d1）将第二液体在足够的压力下引入第一腔（30）中，以便在填充操作结束时将活塞头（7）连接至耦接装置（62）。如果第二腔配备有活塞头（7），那么将第二液体引入所述第二腔中。如果两个腔均配备有活塞头，那么填充仍然空的腔。d1) The second liquid is introduced into the first chamber (30) under sufficient pressure to connect the piston head (7) to the coupling device (62) at the end of the filling operation. If the second chamber is equipped with a piston head ( 7 ), the second liquid is introduced into the second chamber. If both chambers are equipped with piston heads, the still empty chamber is filled.
e1）如果容器将被加压并且气体还没有在步骤c0iii）中引入，可以在已填充液体后引入气体，这通过由塞子关闭的容器底部的孔进行。e1) If the container is to be pressurized and the gas has not been introduced in step c0iii), the gas can be introduced after it has been filled with liquid, this is done through the hole in the bottom of the container closed by the stopper.
可以理解的是，腔（20、30）不会形成，直到产品已填充进去。具有单独的活塞头的腔（在该情况下为第一腔（30））不和其它腔（在该情况下为第二腔（20））同时形成。相反，它直到填充第二产品时才形成。因此，在填充第二产品之前，不需要提供抽吸设备以从填充有第二产品的腔（在该情况下为第一腔（30））提取空气。It will be appreciated that the cavities (20, 30) will not form until the product has been filled therein. The chamber with a separate piston head (in this case the first chamber ( 30 )) is not formed simultaneously with the other chamber (in this case the second chamber ( 20 )). Instead, it does not form until it is filled with the second product. Therefore, there is no need to provide suction means to extract air from the cavity filled with the second product, in this case the first cavity ( 30 ), before filling the second product.
压缩气体例如氮气、氧气和压缩空气以及液化气体例如烃，例如丁烷和异戊烷、二甲基醚和含氟烃，可以特别考虑作为推进剂以排放产品。然而，也可以通过机械系统例如弹簧或者具有回复力的弹性材料例如弹性体来排放产品。Compressed gases such as nitrogen, oxygen and compressed air as well as liquefied gases such as hydrocarbons such as butane and isopentane, dimethyl ether and fluorinated hydrocarbons may in particular be considered as propellants to discharge the product. However, it is also possible to discharge the product by means of a mechanical system such as a spring or an elastic material with a restoring force such as an elastomer.
作为这一点的替代，也可以将阀盘（44）固定至压力容器的外套（5），然后通过压力容器底部的孔填充分配模块（1）并填充气体，该孔随后关闭。如果气体从上方填充，气体必须能够流动地远达底部，例如通过为此目的提供的沟道。As an alternative to this, it is also possible to fix the valve disc (44) to the jacket (5) of the pressure vessel and then fill the dispensing module (1) with gas through a hole in the bottom of the pressure vessel, which hole is then closed. If the gas is filled from above, the gas must be able to flow as far as the bottom, for example through channels provided for this purpose.
本发明要求保护的分配模块的应用领域可存在于例如工业或药物领域、医疗产品领域、食品、化妆品、个人卫生、杀生物剂、消毒剂或漂白剂。此外，可以实现最多样化的产品概念：可以提供反应系统，例如气体生成系统（例如CO2）、硬化系统（例如化学反应，例如链增长、交联、凝聚、聚合，特别是在聚氨酯化学领域）、在适用的情况下存在粘度改变的凝胶系统、活性物质的生成（例如氯、次氯酸盐、H2O2、硫、碘）、酶系统、酸碱系统、温度改变系统（例如放热或吸热混合物）或者粘合剂系统。其它产品概念提供混合物和特定材料性质的生成，例如乳液、分散体、油包水、水包油、水包油包水、香料、添加剂混合物（AM）、活性物质混合物（例如维生素）、着色剂（例如物品和身体部分的着色）、活性消毒混合物以及某些流动或滑动性质。Fields of application of the dispensing module claimed in the invention may be found, for example, in the industrial or pharmaceutical field, in the field of medical products, food, cosmetics, personal hygiene, biocides, disinfectants or bleaches. Furthermore, the most diverse product concepts can be realized: reactive systems such as gas generating systems (e.g. CO2 ), hardening systems (e.g. chemical reactions such as chain growth, crosslinking, coacervation, polymerization, especially in the field of polyurethane chemistry ), gel systems with viscosity changes where applicable, generation of reactive species (e.g. chlorine, hypochlorite, H2 O2 , sulfur, iodine), enzyme systems, acid-base systems, temperature changing systems (e.g. exothermic or endothermic mixtures) or binder systems. Other product concepts offer the generation of mixtures and specific material properties, such as emulsions, dispersions, water-in-oil, oil-in-water, water-in-oil-water, fragrances, additive mixtures (AM), active substance mixtures (e.g. vitamins), colorants (such as coloring of objects and body parts), active antiseptic mixtures, and certain flowing or sliding properties.
