Description

Applying nozzle

Technical field

The present invention relates to be used for and viscous material is introduced for example so relevant method of container of pipe, and relate to the applying nozzle that is intended to be used for described method.The present invention relates to the method for using following nozzle particularly, and described nozzle comprises a more than delivery pipe so that can be by the mode of introducing the different material formation permanent pattern in the container at least two kinds of dissimilar materials are introduced in the same container.The invention still further relates to and be used to the pipe filling machine carrying out described method and comprise above-mentioned applying nozzle, and relate to the application of this applying nozzle.

Background technology

The applying nozzle that known use has many delivery pipes in the prior art is introduced multiple material in pipe or the container simultaneously.A very common field of using such applying nozzle is will be with the field in the toothpaste inlet tube.US Patent 6,418 has illustrated this nozzle in 986, and the inner circular delivery pipe that wherein is used to introduce first material is centered on by second annular duct that is used to introduce second material.Described delivery pipe is arranged with concentric manner.Described nozzle can be coupled to manifold, and described manifold can be coupled to again and is used for for example container of desired substance such as white or red toothpaste.It has also illustrated how to be provided with in order to cut off the valve from the flow of delivery pipe on the aperture of described nozzle.

Fill dentifrice tube in this way and such purpose that comprises by the product of the cream of high viscosity and paste is in order to form a kind of permanent pattern of being made up of different material.When with the described product inlet tube period of the day from 11 p.m. to 1 a.m, must in described pipe, mainly there be two kinds of unmixing materials.In US Patent 6,418, in 986 the example, therefore described pipe will comprise two kinds of whites of separating and red material, and described material will form red-informal voucher line cream when toothpaste is extruded from pipe.

In order to fill pipe smoothly with for example toothpaste of different colours and can to control the pattern of the filling of pipe with generation hope, dominant discharge is necessary reliably.When introducing the toothpaste of different colours, in conventional mechanical by utilizing piston pump to regulate the stream pressure and flow velocity is controlled different material stream.Come the flow of material of self-pumping to be coupled to the inlet delivery pipe on applying nozzle top.So the flow of material of different colours is crossed the delivery pipe that separates in the nozzle.Then, near the exit end of nozzle, the conveying pipeline combinate form of described separation becomes a bigger common delivery pipe.The problem that the type is filled is that the material of being filled separates from nozzle, thereby it is not advanced or following.Carry out this process so that each loading all equates by controlled way, this equally also is important.

Because the piston in the pump carries out rapid movement when finishing the stroke of pump before pump valve cuts out backward, some material according to routine from nozzle separately.Thereby product in the nozzle is by in the inlet nozzle backward.This process is mainly used in has high viscosity but inviscid material.When this method was used to introduce the material of different colours, the problem of generation was, the material that flows to different colours together at the nozzle-end place be not inhaled into its from that delivery pipe.The material that this means different colours mixes together, and the original material stream that occurs when padding next time mixes.

The prevailing method that material and nozzle are separated is the exit end use valve at nozzle.Described valve generally includes the valve cone on the axle that is positioned at the nozzle inboard.Described valve by axle nozzle axially on move back and forth and open and close.According to routine, prevailing is the each several part of the delivery pipe formation nozzle throat area in the nozzle.Described axle and valve cone thereof have been arranged in the center of described cross-sectional plane.When coloring matter occurs and advances to a time-out in the bottom of nozzle from each delivery pipe that separates, their continue to form the each several part around described axle and valve cone.Therefore, when valve cone was closed, described material did not mix.In the nozzle with a delivery pipe that is arranged in another delivery pipe inboard, for example the pipe with a kind of coloring matter at the nozzle center place is centered on by the pipe that another root comprises the material of different colours, can have problems in the bottom of nozzle.When coloring matter when each delivery pipe that separates occurs, they all center in each side spool and valve cone, a kind of material near nozzle center another kind of material in the outside.When valve cone is closed with respect to opening of nozzle, the each several part of the closing surface of valve cone will cut off inside and outside color simultaneously, and each material becomes and mixes thus.Thereby when filling, the original material stream that occurs from described nozzle will mix next time.In addition, turbulent flow takes place around the valve cone, and different material will can not flow out equably but have the trend of mixing at it when nozzle occurs.Therefore, the distribution of color on the cross-sectional plane of the stream that nozzle occurs will change.

Therefore, known so far nozzle exists the direct risk that the material from different delivery pipes becomes and mixes.It is accurate that this means that at first control to flow can not resemble desirable, and will can not be introduced in the container with desirable pattern such as the different material of the toothpaste of different colours in this case.

Therefore, be starved of improved method and apparatus, be used for controlling multiple different material and in such as the container of pipe the time, introduce, filling described pipe, thereby obtain desirable permanent pattern with various materials.Particularly, need can be under the situation that different material does not mix at the place, end of nozzle each flow of material of control, and can form a kind of pattern that from the nozzle dispensable materials time, can not change.

Summary of the invention

Yet, the invention provides a kind of applying nozzle that utilizes the mentioned type of introductory section with the method in the high viscosity material introducing container, described method has solved the problems relevant with previous known method basically.Therefore, the present invention relates to be intended to use the method and the applying nozzle of at least two kinds of material filling containers.This is the general character incident when introducing the toothpaste of different colours in the pipe.In order to make various materials when being introduced into container, keep a kind of pattern, need these materials to advance not together.This is not less than 10 by at least a viscosity in the described material, 000cps (centipoise) or 10PAs (pascal second), preferably be not less than 30,000cps and most preferably be not less than 40,000 or 40Pas, will keep its configuration suitably to realize when the material of high viscosity is in being introduced into container thus.Therefore, term " high viscosity material " means to have and depresses viscosity at 20 ℃, standard atmosphere and surpass 10, the material of 000cps or 10PAs.

Since second or any other material can be by keeping going up in position by the support of high viscosity material more, so it needn't have same high viscosity.Yet, the viscosity of wishing different material usually about equally so that they can for example remove from described container by the extruding pipe equably.If the viscosity difference between the different material of the contents in the formation pipe is too big, those materials that the serious risk of existence is to have quite low viscosity will be squeezed or will at first flow out.

Applying nozzle is provided with at least two delivery pipes at its longitudinal extension.Described delivery pipe in the nozzle also comprises coupling connection portion or the connecting portion that links to each other with the feed duct of some type, and described feed duct is connected to the different hiding-places of every kind of desired substance again.Described delivery pipe along the vertical axis extension of nozzle launches in the position substantially the same with the distant place exit end of nozzle.Of the present invention being further characterized in that, first delivery pipe is provided with first valve that is intended to regulate the flow in first delivery pipe at its place, aperture, and second delivery pipe is provided with second valve that is intended to regulate the flow in second delivery pipe at its place, aperture.This design can be accurately and is accurately controlled corresponding discharge from every different delivery pipes.Actual valve action is set at aperture place, and this has reduced the N/R material and has splashed into or brought into risk in the container downwards.

Thereby different valves must preferably be controlled discriminably, and in other words, the different valves that are used for every delivery pipe at the place, aperture of applying nozzle must be able to open and cut out independently of each other.Yet, may exist and wish to make the opening and close synchronous time of different valves.If so can mechanically link together the different control conveniences that are used for different valves and controls them by common control command.

According to one embodiment of the present of invention, described valve is controlled by so-called axle.Yet using the valve of what type or control convenience is not the essence of real thought of the present invention, and using axle only is a kind of among the many possible detailed technology embodiment in the scope of the invention.

According to another embodiment of the present invention, the connecting portion that described first delivery pipe and second delivery pipe link to each other with corresponding feed duct from them in described applying nozzle is separated from each other to the expanded range in aperture that they are positioned at the far-end of described nozzle.Thereby the flow of material that will introduce the different material in the container all separates from start to finish until expansion place that delivery pipe approaches the far-end of described nozzle.Under most of situation, the real thought that makes nozzle be provided with different delivery pipes be make each flow of material before leaving nozzle orifice be separate and in the material of being filled, give desirable pattern in this way.

Yet, in some cases, may have contact between the different delivery pipes in the nozzle upstream in the aperture of each delivery pipe.In these cases, possible is that for example a kind of mixing to a certain degree of material is fine and also is desirable.Therefore, also can use the valve gear that is used for following types of nozzles described herein, in described nozzle, designed the delivery pipe that is intended to be used for dissimilar materials, make them on it is arranged in the length of described nozzle, be interconnected, and make described different material when flowing through described nozzle, contact mutually.Different delivery pipes can for example be interconnected by the perforate on the partition wall between the delivery pipe.

In one embodiment of the present of invention, first delivery pipe in the applying nozzle and second delivery pipe around along described nozzle longitudinally axis arrange with one heart.In this case, described nozzle can be provided with first delivery pipe of pipe form, and it is centered on by partition wall and separates with second delivery pipe of endless tube form.At this, the form of delivery pipe is appointed as circle or annular.The general design that the favourable part of these forms is not only to have considered desirable pattern (for example when introducing the toothpaste of different colours in the pipe) to a certain extent but also has considered described nozzle and valve to a certain extent.Yet the pattern in order to obtain in the material in introducing container to wish also can make the tube wall of delivery pipe have for example other geometric configuration of rectangle or hexagon etc., and perhaps the aperture with delivery pipe is made as different geometric configuratioies.

For most of embodiment, arrange with one heart that in nozzle first delivery pipe and second delivery pipe are favourable.Yet this is optional to the present invention, if wish, for example also can use nonconcentric(al) layout to obtain special filling pattern.

The valve that is arranged in the place, aperture can and can have different functions for polytype.According to an embodiment, described valve only can be designed to a great extent and can regulate between the second place that primary importance that described valve is opened and described valve are closed.In this case, for example be coupled to flow in any inlet pipe of described nozzle by control, control will be introduced in the amount from the different material of every delivery pipe in the container basically.

According to another embodiment, the valve at place, the aperture of applying nozzle is designed to make them to can be set to be opened to different degree.In this case, described valve can or have many prepositions makes the opening degree only can be classified to control cock, or can regulate continuously and make it be set on the desirable analog position.In this embodiment, can be individually or mainly by the adjusting of orifice valves being regulated control to flow.

In the above-described embodiments, the present invention has only illustrated the nozzle of the delivery pipe that is used for different material with two separation.Naturally, then can connect the 3rd delivery pipe and other extra delivery pipe if desired.

Described delivery pipe has circular cross sectional shape for purposes of the invention neither be essential, can use any other suitable shape, for example square, triangle, polygon, ellipse or other shape.

The invention still further relates to the filling machine that is used to fill such as the container of pipe or distributing box, it comprises the applying nozzle according to the foregoing description.Can be advantageously used in the pump dynamic formula distributing box of filling dentifrice tube and being used for polychrome toothpaste according to filling machine of the present invention.Also can use distributing box such as other types such as squeeze bottle.The material of being filled can be dissimilar thickness cosmetics alternatively---, perhaps being viscous food---such as jam or marmalade, baste, dough, caviare, soft cheese etc. such as face cream and washing lotion.

The invention still further relates to the use of all nozzles as described in this, it is used for so that the mode that forms permanent pattern by the different material of introducing container is introduced dissimilar thick substances in the same container, and one of them kind material is the high viscosity material.

Therefore, existence falls into to provide and has the multiple apparatus and method according to thought range of the present invention that are intended to be used at least two delivery pipes of different material and are provided with the valve of separation at the place, aperture of described delivery pipe.

The specific embodiment

Fig. 1 illustrates the applying nozzle 1 according to one embodiment of the invention.Shown in applying nozzle 1 be nozzle vertically on along the cross-sectional plane of the central axis of nozzle 1.Nozzle 1 comprises first inner duct 2 and second outer carrier pipe 3.These

delivery pipes

2,3 are annular, and in an illustrated embodiment, they are arranged with one heart around the central axis of applying nozzle 1.Axle 4 in applying nozzle 1 also comprises, described interior axle are arranged in first inner duct 2 and constitute the inwall of inner duct 2.Applying nozzle 1 also comprises outer shaft 5, and described outer shaft is arranged between first inner duct 2 and second outer carrier pipe 3, thereby it constitutes the outer wall of inner duct 2, the inwall of outer carrier pipe 3.In the described outer carrier pipe outside, filling nozzle 1 is provided with the shell 6 of the outer wall that constitutes second outer carrier pipe 3.In axle 4 top or remote design for serving as first inner valve 7, and on geometric configuration, be designed to be complementary, so that the flow in the energy restricted internal delivery pipe 2 with the aperture 8 of described inner duct.By the displacement along the central axis of applying nozzle 1 of interior axle 4 with respect to the outer shaft 5 in the aperture 8 that comprises inner duct, inner valve 7 can switch to off position from open position.Similarly, the top design of outer shaft 5 is for serving as second external valve 9, and it is designed to be complementary with the aperture 10 of described outer carrier pipe, so that can limit the flow in the outer carrier pipe 2.External valve 9 adopts the mode identical with inner valve 7, can be closed and open by the displacement along the central axis of applying nozzle 1 of outer shaft 5 with respect to the shell 6 in the aperture 10 that comprises outer carrier pipe.First inner duct 2 of applying nozzle 1 also is provided with first connecting portion 11, and described first connecting portion can be coupled to first feed duct that is used to carry first material that will be introduced into container.Similarly, second outer carrier pipe 3 is provided with second connecting portion 12, and described second connecting portion can be coupled to second feed duct that is used to carry second material.As shown in FIG., inner duct 2 is all separated on whole common length in its

aperture

8,10 from connecting

portion

11,12 to the far-end 13 that is positioned at applying nozzle 1 with outer carrier pipe 3.

Fig. 2 a-2d illustrates the enlarged drawing of the far-end 13 of applying nozzle 1.Fig. 2 a illustrates inner valve 7 and how to be shown in an open position with external valve 9.Since interior axle 4 and outer shaft 5 the two on nozzle vertical along the central axis of nozzle 1, the flow direction of material is opposite with filling containers time the direction superior displacement, obtain this position.In this way, inner openings 8 is kept with outer aperture 10 and is opened, thereby two kinds of materials can side by side flow and filling containers.

In Fig. 2 b and since interior axle 4 nozzle vertically on along the central axis of nozzle 1, be shifted on the direction of the flow direction of material when being parallel to filling containers, described position is compared with the position of Fig. 2 a change has been taken place.Thereby the aperture 8 of described inner duct is closed, and material will only be introduced in the described container by outer carrier pipe 3 during filling.

In Fig. 2 c and since outer shaft 5 nozzle vertically on along the central axis of nozzle 1, be shifted on the direction of the flow direction of material when being parallel to filling containers, described position is compared with the position of Fig. 2 b change has been taken place.This will produce two variations on the valve position of two delivery pipes 2,3.Because outer shaft 5 constitutes the outer wall of inner duct 2 and comprises the aperture 8 of described inner duct, the change of outer shaft 5 positions means the inner valve 7 at the top that constitutes interior axle 4 with respect to the internal openings displacement, thereby inner duct 2 is opened.On the other hand, will close the aperture 10 of described outer carrier pipe, and only make material from inner duct 3 filling containers by the displacement that comprises the axle 5 that external valve 9 is outer.

In Fig. 2 d and since interior axle 4 nozzle vertically on along the central axis of nozzle 1, be shifted on the direction of the flow direction of material when being parallel to filling containers, described position is compared with the position of Fig. 2 c change has been taken place.Thereby the aperture 10 of described inner duct also is closed, and then can not carry out the filling of container.

Embodiment according to Fig. 1 and the described applying nozzle of the present invention of Fig. 2 only is an example, will it not be considered as restrictive optional embodiment of the present invention.Can see that in shown example for example outer shaft is configured for the valve of outer carrier pipe and the outer wall and the aperture of inner duct simultaneously.In design item, these functions can be separated feasible partition wall and movable axie or valve layout of fixing between each delivery pipe by using another kind of valve to realize by sliding along described fixation wall.In addition, the valve position that mainly only illustrates or open or close in the example shown in this.As having pointed out under title " summary of the invention ", under the situation that does not deviate from inventive concept, position that can control cock changes the flow size.
