Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to counter apparatuses for beverages dispensing and in particular to a modulated manifold system for distribution of post-mix and pre-mix beverages.




2. Description of Related Art




The word manifold system is used in the field of post-mix and pre-mix beverages distribution to indicate the part of the distributing apparatus comprised between the refrigerating device and the beverages dispensing front part and having the aim of feeding the taps of the dispensing front part with pre-mix beverages, syrups, still water and carbonated water necessary to obtain post-mix beverages.




The word post-mix beverage indicates beverages prepared by the producer as syrup or concentrated beverage which need to be diluted with still water or carbonated water before being dispensed. The word pre-mix beverage indicates beverage to be dispensed as prepared by the producer.




In the prior art manifold systems are constituted by units having as inlet the pipelines coming from the refrigerating system and carrying beverages, still water, carbonated water for diluting post-mix beverages, and the fluid (generally water) used for the cooling of the system. The manifold system depends on the type of dispensing front part to which the system has to be connected and in particular from the number and types of taps, such as post-mix taps with still water, post-mix with carbonated water and pre-mix, which such front part includes.




The inconveniences of the modular manifold systems according to such prior art are basically due to the necessity to manufacture different types of units according to the number and types of the taps disposed on the dispensing front part. Furthermore once the apparatus has been mounted it is almost impossible to modify the types of taps on the dispensing front part.




A further problem shown by the known systems is the maintenance which is difficult because, almost always, it is necessary to disassemble the whole dispensing front part even when the problem concerns only a single line.




The aim of the present invention is a modular manifold system which obviates the necessity of manufacturing different types of units according to the number and types of taps disposed on the dispensing front part.




Another aim is to allow, once the apparatus has been mounted, changing of one number and type of the taps on the dispensing front part.




A further aim is to allow the mixing of still water and carbonated water inside the same system to obtain a diluting water of the post-mix beverages with a gassing more suitable to the different types of beverages.




Another aim is to facilitate the assembly maneuvers and maintenance services.




Still another aim is to obtain a modular manifold system of easy and inexpensive manufacture without suing specialized workpeople or sophisticated technologies.




These and further aims are achieved by the modular manifold system according to the invention.




BRIEF SUMMARY OF THE INVENTION




The modular manifold system of the present invention comprises: at least two units connected to each other. Inside each unit two transversal channels are placed, such channels being suitable for transporting the pre-mix beverages and the syrups for the post-mix beverages, such channels being outside communicating in order to be connected to outside feeding and dispensing three longitudinal channels suitable for transporting water, carbonated water and the refrigerating fluid, and being said modular channels adjacent and communicating with each other. Each unit also compresses three transversal channels outletting on said three longitudinal channels and being outside communicating in order to be connected to outside feeding devices. Each unit comprises a regulating means which allows choosing between water or carbonated water dilutes the syrup, and furthermore allows the regulation of the inflow of the two types of water to a mixing chamber placed inside the same unit and communicating outside through suitable channels. Each unit is further provided with gate valves which allow the opening and the closing of the channels suitable for transporting the pre-mix beverages and the syrups.




The present invention allows, because of its modular shape, feeding for a number of dispensing taps which can be freely varied. Thanks to the inner pipeline, to the regulating means and to the gate valves present on each unit, it is possible to vary the type of dispensing taps fed by the single unit. Furthermore it is possible, by means of the mixing chamber and of the regulating means placed on each unit, to mix still water and carbonated water in order to freely vary the gassing of the post-mix beverage supplied by the single unit.

These holes are used to fix to the body


2


the terminal parts


5


and


6


through the suitable passing pins working as a connector. As shown in

FIGS. 7

,


8


,


9


the body


2


is longitudinally crossed by three channels having circular section


14


,


15


and


16


, wherein the channel


14


is the channel transporting blow-by water for the cooling, the channel


15


transporting the water and the channel


16


transporting the carbonated water. Such channels outlet on the opposite surfaces


11


and


21


. On the surface


21


corresponding to said channels three annular grooves


34


,


35


and


36


are carried out such that the same channels


14


,


15


and


16


project out with a cylindrical portion, allowing in such a way the connection among the corresponding channels


14


,


15


and


16


of two jointed modular units. The seal of the fluids passing through the channels and consequently through the modular units, is obtained through the O_rings


37




a,




37




b


and


38


. The outside feeding of the longitudinal channels


14


,


15


and


16


is obtained through the transversal channels


17


,


18


and


19


, the channels outletting on the rear surface


60


. They are fed by external pipelines connected to the body


2


through the holes


52




a


and


52




b.


The channels


14


,


15


and


16


of the units at the terminal side parts of the system have the terminal portions placed in contact outside respectively with the parts


5


and


6


closed through a suitable cap (not shown in figure). The same condition is for the feeding channels


17


,


18


and


19


of the intermediate units


1




b


and


1




c


of the embodiment shown in

FIG. 1

which are closed with suitable cap (not shown in figure). The channel


17


is constituted by two cylindrical portions


68


and


69


having circular section of different diameters. The channel


18


is constituted by two cylindrical portions


70


and


71


having circular section of different diameter and the channel


19


is constituted by two cylindrical portions


72


and


73


having circular section of different diameter, the portions having the larger diameter


68


,


70


and


72


outletting on the surface


60


and having the same length, the portions having the minor diameter


69


,


71


and


73


outletting on the corresponding longitudinal channels. The length of these second portions depends on the distance of the axis of the longitudinal channel from the surface


60


. The longitudinal channels


15


and


16


, as shown in

FIG. 5

, can feed through the vertical cylindrical channels


26


and


27


having a circular mixing chamber


28


. The inflow of the still water and of the carbonated water into the mixing chamber


28


is controlled through the regulating means


23




a


and


23




b


and the nonreturn valves


24




a


and


24




b.


The nonreturn valves are constituted by the spear valves


48




a


and


48




b


made in gummy resin, by the stems


49




a


and


49




b


and by the springs


50




a


and


50




b.


the spear valves


48




a


and


48




b


are constituted by a cylindrical drilled portion which houses a terminal part of the stems


49




a


and


49




b,


and by a truncated-core portion. The spear valves rest on the beating annular surfaces


30




a


and


30




b.


Through the surfaces


29




a


and


29




b


having an overturned cone shape, they can move axially inside the chambers


31




a


and


31




b


having a cylindrical shape with circular section. The shape of the spear valves


48




a


and


48




b


allows that the possible presence of fluid in the chambers


31




a


and


31




b


coming from the mixing chamber


28


squash the same spear valves on the surfaces


30




a


and


30




b


preventing the passage of the fluid from the chamber


28


to the vertical feeding channels


26


and


27


. A portion of the stems


49




a


and


49




b


and the springs


50




a


and


50




b


are housed inside the regulating means


23




a


and


23




b.


The means


23




a


and


23




b


have the annular grooves


62




a


and


62




b


inside which the O_rings


63




a


and


63




b


are housed. Such regulating means can move inside the chambers


32




a


and


32




b.


Both the regulating means and the chambers


32




a


and


32




b


have threaded surfaces (not shown in figure) which allow the axial movement of the same elements. The chambers


32




a


and


32




b


are carried out inside the cap


33


of the mixing chamber


28


. The terminal portions of the regulating means


23




a


and


23




b


facing the superior surface


41


of the body


2


have the diametrical grooves


64




a


and


64




b


with which it is possible to vary the axial position of the same elements inside the chambers


32




a


and


32




b.


Such movement causes the changing of position of the spear valves


48




a


and


48




b.


The bigger the displacement downwards of the means


23




a


and


23




b,


then it is minor for the possibility of the spear valves to disjoin from the supporting surfaces


30




a


and


30




b.


Obviously the extreme condition is the closing of the feeding channels


26


and


27


of the mixing chamber


28


. The cap


33


of the mixing chamber


28


has a cylindrical shape and it is housed in the chamber


20


. It has an almost circular section and it is constrained to the body


2


through the screws


59




a


and


59




b,


in order to allow the seal of the chamber


28


in the annular groove


43


of the cap


33


of the O_ring


44


is inserted. The mixing chamber


28


is connected through the vertical channel


53


having an elliptical section, to the transversal channel


54


, such channel having a circular section projecting out from the body


2


with a cylindrical portion


74


housing the set as for possible sealing O_rings for the connection with the outside dispensing devices. The body


2


is transversally crossed by the channels


39


and


40


shown in

FIG. 13 and 14

. Beverages come to these channels, in particular the syrup arrives to channel


39


, whereas to channel


40


a syrup or a pre-mixed beverage can come. The channel


39


has a terminal portion


75


which comes out from the body


2


housing the seats for possible sealing O_rings for the connection with the outside dispensing devices. The channels


39


and


40


can be closed through the gate valves


65




a


and


65




b


constituted by the caps


76




a


and


76




b


and by the drilled cylindrical elements


77




a


and


77




b


made in gummy resin, connected to the caps


76




a


and


76




b


through a pivot (not shown in figure). The gate valves


65




a


and


65




b


move inside the chambers


67




a


and


67




b.


Both the gate valves and the chambers have threaded surfaces (not shown in figure) to allow the axial movement of the gate valves. The axial position is controlled using the diametrical grooves


78




a


and


78




b


disposed at the superior terminal portion of the caps


76




a


and


76




b.


The axial movement of the gate valves


65




a


and


65




b


causes the opening or the closing of the transversal channels


39


and


40


. The seal is obtained through the O_rings


66




a


and


66




b


carried by the caps


76




a


and


76




b


in the annular grooves


79




a


and


79




b.






Each described modular unit can be used to supply a pre-mix tap, in such case the transversal channel


39


will be closed using the gate valve


65




b


and the transversal channel


54


using the regulating means


23




a


and


23




b


in order to close the vertical channels


26


and


27


. Furthermore, the adapter


7


is inserted as shown in FIG.


15


. The adapted


7


is comprised of drilled pate


85


having a drilled truncated-cone position


86


presenting the thread


87


in order to allow the connection with the rear threaded portion


25


of the tap


4


.




The unit can as alternative be used to supply one or two taps for post-mix beverages. In the first case only the transversal channel


39


is fed and the transversal channel


40


is closed through the gate valve


65




a.


In the second case the transversal channels


32


and


40


are fed and the outlet of the channel


40


is modified through the adapter


8


, shown in FIG.


16


. The adapted


8


comprises two cylindrical portions


80


and


88


, of which the portion


80


having a larger diameter is housed in the channel


40


, and the portion


88


having a smaller projects out from the body


2


in order to be connected to the dispensing front part. In

FIG. 16

, it is further shown a tap


89


suitable to the dispensing of two post-mix beverages.




It is possible to adapt the system to any dispensing front part combining opportunely the several units, making the system easy to change.




The single unit can be used for post-mix non carbonated beverages or for post-mix carbonated beverages with the possibility of relating the dilution of the carbon dioxide inside the water using the regulating means


23




a


and


23




b.


As it is shown in

FIG. 17

only the modular unit


1




a,


positioned at one terminal side part of the set of units, is connected directly to the cooling apparatus for the supplying of still water, through the pipeline


81


and for the carbonated water through the pipeline


82


. The modular unit


1




a


is further fed with blow-by water through the pipeline


83




a,


water which is carried back to the cooling coils through the pipeline


83




b


connected to the modular unit if placed at the other terminal side part of the set. The intermediate modular units


1




b,




1




c,




1




d


and


1




e


are fed with the still water, carbonated water and refrigerating water through the longitudinal channels


14


,


15


and


16


which are connected between the modular adjacent units, whereas each unit is fed directly with the respective pre-mix or post-mix beverages through the channels


84




a,




84




b,




84




c


,


84




d,




84




e


and

c


,


3




d


and


3




f


and by the pre-mix tap


4


, using the means


23




a


and


23




b


it is determined the opening or the closing of the longitudinal channels


15


and


16


. As schematically shown in

FIG. 18

, the taps


3




b,




3




c


and


3




d


are in such a way post-mix taps with still water, with carbonated water and with diluted carbonated water and the tap


4


is a pre-mix tap mounted directly on a modular unit in which the channels


15


and


16


have been closed. The same dispensing front part is shown in

FIG. 19

wherein the elements


90


and


91


are the units obtained according to the state of art. The unit


90


supplies the post-mix taps


3




a


and


3




b


with still water coming from the pipeline


81


. The unit


91


supplies the post-mix taps

c,




84




d,




84




e


and


84




f.


The pre-mix tap


4


is mounted on a supporting member (not shown in figure) different from said units because it does not need dilution water.




The modular units carried out according to the present invention allow mounting the post-mix taps directly on the single units through the holes


58




a,




58




b,




58




c


and


58




d


without the necessity of inserting intermediate valve bases having the aim to allow the interruption of the inflow of still or carbonated water and of the syrup when the taps are dismounted. The presence of the regulating means


23




a


and

b


and the gate valves


65




a


and


65




b


allow the same unit to carry out such operation. In case of maintenance service it is possible to remove and substitute the single modular unit as shown in FIG.


1


and

FIG. 1



a


without being forced to dismount the adjacent units, because the simple connection system is based upon the joint connection, which furthermore prevents the use of possible intermediate joints increasing the sealing of the whole dispensing front part.




The present invention is suitable to variations and changing all belonging to the same inventive concept, furthermore all the details can be substituted with other technically equivalent elements.
