Definitions

  • the present invention relates to a tapping head for pressurized beverage dispensing systems.
  • the present invention relates to a tapping head for pressurized beverage dispensing systems, the tapping head being of the type comprising a tubular member having an axis and, in turn, comprising a bell coaxial with the axis and having, at an open first end, connecting means for connection to an outlet neck of a relative barrel, and a tubular body coaxial with the axis, communicating with the inside of the bell, and integral with a second end of the bell opposite the first end; a first conduit formed through the tubular member to feed a pressurized gas into the bell; and a first valve device comprising a tubular slide member, which is coaxial with the axis, has a second, through axial, conduit communicating with the bell, and is mounted to slide along the tubular member between an extracted position opening both the outlet neck and the first conduit, and a withdrawn position disconnected from the outlet neck and closing the first conduit.
  • the present invention may be used to advantage in systems for pressurized dispensing beverages in general, such as beer, to which the following description refers purely by way of example.
  • Pressurized beer dispensing systems are known to employ at least one tapping head of the type described above to supply a tap dispenser, via a feed circuit, with beer from a barrel normally located remotely with respect to the tap dispenser.
  • the tapping head of known systems of the type described above is detached from the outlet neck of the barrel and connected to a similar outlet neck of a wash fluid dispensing circuit, which feeds the wash fluid along the entire feed circuit and out through the tap dispenser.
  • the tapping head is then fitted back onto the barrel, or a new barrel, to resume operation.
  • a known tapping head of the type described above therefore in no way provides for automatic washing, and must always be detached manually from the barrel and connected manually to the wash fluid dispensing circuit.
  • a tapping head as claimed in Claim 1 and, preferably, in any one of the Claims depending directly or indirectly on Claim 1.
  • Figure 1 shows, schematically, a beer dispensing system incorporating a preferred embodiment of the tapping head according to the present invention
  • Figure 2 shows a larger-scale side view of the Figure 1 tapping head
  • Figures 3 to 5 show the Figure 2 tapping head in respective different operating configurations
  • Figure 6 shows a larger-scale, exploded detail of Figure 3;
  • Figure 7 shows a larger-scale section along line VII-VII in Figure 3;
  • Figure 8 shows a partly exploded, top plan view of the Figure 6 detail.
  • FIG. 1 indicates as a whole a system for pressurized dispensing a beverage by means of a tap dispenser 2 controlled by a lever 3 for opening a faucet 4 controlling dispenser 2.
  • dispenser 2 dispenses beer tapped selectively from a series of barrels 5 used successively, and each of which is connected to dispenser 2 by piping 6 comprising a header 7, a conduit 8 connecting header 7 to dispenser 2 and common to all of barrels 5, a tapping head 9 fitted removably to barrel 5, and a conduit 10 connecting tapping head 9 to header 7.
  • System 1 also comprises a circuit 11 for selectively feeding pressurized gas to each of barrels 5 from a cylinder 12.
  • Circuit 11 comprises a header 13 common to all of tapping heads 9; a conduit 14 common to all of tapping heads 9 and extending through faucet 4 to connect cylinder 12 to header 13; and, for each tapping head 9, a conduit 15 connecting header 13 to tapping head 9.
  • System 1 also comprises a wash circuit 16, in turn comprising piping 6 on one side, and, on the other, feed piping 17 for feeding wash fluid to each tapping head 9.
  • Feed piping 17 comprises a valve 18, possibly comprising a drain outlet (not shown) which, by simultaneously cutting off wash fluid supply and first opening dispenser 2, may be opened selectively to drain out any wash fluid from piping 17 and tapping head 9.
  • valve 18 is controlled by a central control unit 19 operated from a pushbutton control panel 20 having a number of buttons 21, each for controlling a standard wash and tap cycle for a relative barrel 5, and a further button 22 for controlling a discretionary wash cycle of the currently used barrel 5.
  • each tapping head 9 comprises a tubular member 9a having a connecting device 23 at the bottom for connection to a flange 24 extending outwards from the top of an outlet neck 25 of a relative barrel 5.
  • barrel 5 has a valve 26 comprising a fixed outlet conduit 27, which is coaxial with the axis of neck 25 and has lateral openings 28 and a circular axial cover plate 29; and an annular plate 30 fitted to outlet conduit 27 and movable, in opposition to a spring
  • Tubular member 9a comprises a downward-facing bell
  • connecting device 23 which comprises an annular flange 34 having a C-shaped section with its concavity facing radially inwards and defining an annular groove 35 coaxial with an axis 36 of bell 32.
  • Flange 34 is interrupted at a lateral opening 37 by which to insert neck 25 of a barrel 5 transversely inside bell 32 and into a position, coaxial with axis 36, in which flange 24 engages annular groove 35 to connect bell 32 and barrel 5 axially .
  • Bell 32 is closed at the top by a top wall 38 perpendicular to axis 36 and for connecting bell 32 to a tubular body 39, which, together with bell 32, defines tubular member 9a, and has an open-topped, cylindrical axial hole 40 coaxial with axis 36 and communicating at the bottom with the inside of bell 32 via two chambers 41 and 42 arranged in series and coaxial with axis 36.
  • Chamber 41 is cylindrical and located above chamber 42, which has a top surface defining an annular shoulder with an inside diameter equal to the outside diameter of chamber 41.
  • lateral wall 33 has two diametrically opposite openings 43, one of which is located directly over lateral opening 37.
  • Two superimposed annular seals 44 coaxial with axis 36, extend through openings 43 and define a gap 45 for fluidtight passage, through bell 32, of the movable gate member of a valve device 46, which defines, inside bell 32 and above gap 45, a chamber 32a closed in fluidtight manner at the bottom and communicating at the top with axial hole 40 of tubular body 39.
  • the movable member is defined by a plate 47 perpendicular to axis 36, having a through hole 48 with a diameter equal to the inside diameter of lateral wall 33, and movable, crosswise to axis 36, between a forward open position ( Figures 3 and 4), in which hole 48 is coaxial with axis 36, and a withdrawn closed position ( Figure 5) , in which a solid end portion of plate 47 closes the part of bell 32 over gap 45 in fluidtight manner to define chamber 32a.
  • plate 47 of valve device 46 defines an end arm of an L-shaped bracket 49, another arm of which, parallel to axis 36 and projecting laterally with respect to plate 47, is connected to the end of a screw 50, parallel to plate 47, of a known screw-nut screw coupling (not shown) controlled by an electric motor reducer 51 - preferably a direct-current motor reducer - fitted laterally to tubular body 39 to move plate 47 between the forward open and withdrawn closed positions.
  • Bracket 49 is fitted with a hook 52 facing lateral opening 37 of flange 34, and which substantially closes lateral opening 37 by locking, in use, onto flange 24 of barrel 5, when plate 47 is in the forward open position, to lock tapping head 9 mechanically to barrel 5.
  • a substantially radial conduit 53 is formed through lateral wall 33 of bell 32, communicates at its inner end with chamber 41, and is connected at its outer end to the outlet of relative piping 17 of wash circuit 16.
  • a toroidal chamber 34a (optional) is formed inside lateral wall 33 of bell 32, is coaxial with axis 36, and communicates with a substantially radial conduit (not shown) for supplying coolant by which to cool bell 32 and limit the formation of bacteria.
