An appliance for carrying out this process comprises at least two containers (20, 22), for example cartridges of a two-component sealing compound or the like, the outflow connection pieces (24, 26) of which are arranged parallel and next to one another and connected to one another for joint coupling to a mixer. At least one of the outflow connection pieces (24, 26) has an outflow spout (32, 34) which projects transversely relative to the material strand in the direction of the other outflow connection piece and penetrates into the material strand of the latter and which emits a layer-shaped stream, whilst the other outflow connection piece is provided with a corresponding recess.
Description
PROCESS AND APPLIANCE FOR PREMIXING PASTY MATERIALS.
The invention relates to a process for premixing at least two pasty materials during introduction into a mixer. Furthermore it relates to an appliance for carrying out this process, having at least two containers for the : pasty materials to be mixed, the outflow connection pieces of which are arranged parallel and next to one another and connected to one another for joint coupling to a mixer.
The invention is provided especially for pairs of cartridges or dual cartridges which contain the two components of an adhesive or sealant or
1 u the like. The outflow connection pieces of pairs of cartridges of this kind usually have a semicircular cross-section, so that they complete one another to form a circular cross-section and make it possible to screw on a following static mixer. In other mixing operations, more than two components can also be combined.
! 5 For a homogeneous intermixing of pasty materials, a conventional static mixer requires 24 mixing elements or more which necessitate a very high feed pressure, so that a user's manual force is no longer sufficient to press the materials through the mixer, and a feed pump must be used. This makes the use of cartridges of the present kind considerably more difficult 0 and, in many instances, impossible, since a feed pump is not always available.
The objective of the invention is therefore to provide a process and an appliance for carrying out this process, which make it possible to premix pasty materials effectively as early as when they come out of the 5 corresponding outflow connection pieces.
In a process of the above type, this objective is achieved, according to the invention, in that the material strands supplied to the mixer form thin layers contiguous with one another.
The premixing of the materials which takes place in this way affords 0 the possibility of reducing the number of mixing elements of the following static mixer. For an at least equally good intermixing and therefore also for equally high strength values after the setting of a two-component adhesive or sealing material, the feed pressure required is lower. The materials can therefore be pressed out by hand and there is no need for a feed pump.
~ ~ The individual layers are preferably planar and relatively thin and lie parallel and next to one another.
During the subsequent action of the mixing elements of the static
- mixer, the layered arrangement of the pasty materials leads to a relatively rapid and intensive mixing. However, the mixing effect of the following mixer can be fully used only when the plane of the mixing elements is nearly perpendicular to the layers of material.
According to a preferred embodiment of this process, at least one of the two material strands has a zigzag-shaped or corrugated cross-section. A division of the two material strands by the mixing elements thus takes place independently of the mutual angular position. The appliance according to the inventioa of the type mentioned above, is characterized in that at least one of the outflow connection pieces has an outflow spout which projects transversely relative to the material strand in the direction of the other outflow connection piece and penetrates into the material strand of the latter and which supplies a layer-shaped part stream, and in that the other outflow connection piece is provided with a corresponding recess.
Preferably, in accordance with conventional constructional shapes, the outflow connection pieces have an essentially semicircular cross-section to be completed to form a circle. At the same time, outflow spouts engaging in one another and extending obliquely beyond the parting plane between the outflow connection pieces project from the two outflow connection pieces in the direction of the other outflow connection piece. These outflow spouts preferably have a rectangular narrow outlet cross-section which allows a layer-shaped material strand to be supplied. Alternatively, the outlet surface of the outflow spouts can also be made zigzag-shaped or corrugated.
The two containers preferably form a dual cartridge for two pasty materials to be mixed with one another. The outflow connection pieces of the two containers form the dual-cartridge neck equipped with an external thread Preferred exemplary embodiments of the invention are explained in more detail below by use of the accompanying drawings.
Figure 1 illustrates a diagrammatic side of view and top view of an embodiment of the invention ;
Figures 2 to 4 are further views of the outlet surface of outflow connection pieces according to the invention ;
Figure 5 is an arrangement consisting of a dual cartridge and of a static mixer.
Figure 1 shows, in the lower region, a diagrammatic view of two cartridges 20 and 22 to be connected to one another, in the middle region a top view of their outflow connection pieces, and in the upper region the internesting of the outflow connection pieces after they have been joined together.
The two cartridges 20 and 22 serve for receiving the materials A and B and have a different volume according to the proportion of these materials in the finished mixture.
As represented partially only by broken lines in Figure 1, the two outflow connection pieces 24 and 26 have a semicircular cross-section which is completed to form a circle. There extend from the planar interfaces 28, 30 of the two outflow connection pieces 24, 26 outflow spouts 32, 34 which run obliquely upwards and in the direction of the other respective outflow connection piece and to which recesses in the other outflow connection piece correspond and which engage in one another in a comb-shaped manner. The material strand of material A is once again shown in cross-section with right-hand hatching, and the material strand of material 5 is shown with left-hand hatching. The outlet surface of the outflow spout 34 has a flat rectangular cross-section, so that the material B is introduced as an essentially layer-shaped material into the remaining strand of material A. The upper region of Figure 1 shows a top view of the outflow connection pieces 24 and 26 after they have been joined together.
The outer faces of the outflow connection pieces 24, 26 together form an external thread 36 which allows on the one hand the screwing on of a closing cover and on the other hand the screwing on of a static mixer, as will be explained in more detail later.
The conventional use of the invention will be the premixing of two- component materials, but the invention does not exclude the possibility of mixing in a third or further material. Figure 2 is a top view of two connected outflow connection pieces for the materials A and B in a somewhat enlarged representation corresponding essentially to Figure 1. Here, a layer of the material B is mixed into the accordingly recessed material strand of the material A.
Figure 3 shows an embodiment in which the outflow spout 38 of the outflow connection piece 26 located on the right in the drawing has two parallel outlet surfaces in the form of elongate rectangles and accordingly consists of two separate projecting spout elements 40, 42
Figure 4 shows a corresponding top view of two interconnected outflow connection pieces 24 and 26 with outflow spouts 44 and 46, of which the outflow spout 44 corresponds to the outflow spout 34 according to Figure 2, whilst the outflow spout 46 has a zigzag-shaped outlet surface for the material B. Instead of the zigzag shape, further patterns, for example a corrugated shape, a diagonal or another shape with a changing direction of the outflowing layer of the material B, come under consideration.
Figure 5 shows a diagrammatic representation of the two assembled cartridges 20, 22, with mixing elements 48, 50 which are screwed onto the interconnected outflow connection pieces 24. 26, not shown in Figure 5, and which belong to a static mixer. The mixing elements are held by means of a union nut (not shown) on the outflow connection pieces 24, 26 joined together to form a cylindrical shape and equipped with a common external thread
