The valves (5, 6, 12, 22 and 24) are mounted densely to each other and are a compact valve unit (36). The electromechanical drive of the valves (5, 6, 14, 22 and 24) has a handle (37) for manually rotating the disk (26) having a rammed surface (28), said handle being used when adjusting the automatic device or switching off the electric power supply of the motor (27).
In the second embodiment, the assembly (9) for clamping the neck of the container (10) to the outlet opening of the filling channel (2) and to the inlet opening of the gas removal channel (11) is disposed below the container (10) and comprises a platform (38) for accommodating said container (10) thereon and a mechanism (39) for vertical reciprocal movement of the platform (38), said mechanism being kinematically coupled to the platform (38). The platform (38) is mounted coaxially with a resilient elastic sealing ring (40) disposed on the outer side of the housing (1) of the automatic device around the outlet opening of the channel (2) and the inlet opening of the channel (11). The mechanism (39) for vertical reciprocal movement of the platform (38) is made, for example, in the form of a “bolt-nut” or “tenon-mortise” screw pair with a hand drive or a drive from an electric motor (41). The electric motor (41) is coupled to the control unit (14).
The automatic device operates in the following way. When the device is switched on, the disk (26) having cams (28) is, mounted into its starting position, the presence of pressure in the gas supply pipe (7) is checked and the switching to a waiting mode is performed.
A beverage is poured in the following way. An operator mounts a plastic container (10) onto the fork (35) (
The control unit (14) (controller) triggers the electric motor (27) for stepped rotation of the disk (26) having a rammed surface (28).
In the first embodiment of the assembly (9) for clamping the container (10), first the stem (33) is outpressed and the valve (22) for supplying a gas into the cavity (18) above the piston (17) is opened. The, plastic container (10) is tightly clamped to the resilient elastic ring (21) for communicating its inner cavity with the outlet opening of the filling channel (2) and the inlet opening of the channel (11).
In the second embodiment of the assembly (9) for clamping the container (10), an operator manually rotates the handle (not shown in the figures) of the “bolt-nut” or “tenon-mortise” drive, or the electric motor (41) is switched on by means of the control unit (14), the motor rotating the “bolt-nut” or “tenon-mortise” drive, whereby the Platform (38) ascends and the neck of the container (10) is tightly clamped to the sealing ring (40). Further, the disk (26) rotates into a position (
In the first embodiment of the assembly (9), when the pressure in the container (10) is equalized to the atmospheric pressure, the subsequent rotation of the disk (26) provides for the movement of the stem (34), the opening of the valve (24) and the pressure relief from the cavity (18), alter which the disk (26) stops and the spring (19) returns the piston (17) into its starting position, the neck of the container (10) is released and the container (10) is removed by an operator from the fork (35). After the disk (26) makes a complete stepped revolution, all the valves (5, 6, 12, 22 and 24) are in their initial closed state.
In the second embodiment of the assembly (9), when the pressure in the container (10) is equalized to the atmospheric pressure, the disk (26) makes a complete stepped revolution and all the valves (5, 6, 12) are in their initial closed state. An operator manually rotates the handle (not shown in the figures) of the “bolt-nut” or “tenon-mortise” drive in the reverse direction, or the electric motor (41) is switched on by means of the control unit (14), the motor rotating said “bolt-nut” or “tenon-mortise” drive in the reverse direction, whereby the platform (38) descends, the neck of the container (10) is released and the container (10) is removed by the operator from the platform (38).
After the operation is finished, the automatic device, is washed (washed with water every day, and washed with acid once a week), which is carried out in the following way. An operator, instead of a keg with beer, connects a washing liquid keg, mounts the container (10) of a small volume onto the fork (35) and starts a washing mode. At this moment, the control unit (14) switches on the drive (the electric motor 27) for the stepped rotation of the disk (26) having a cammed surface (28). This opens the valve (22) for supplying a gas into the cavity (18) and the piston (17) descends to clamp the container (10) to the openings of the channels (2, 11) and to the fork (35). Further, the disk (26) having cams rotates to open the valve (5) for supplying a gas into the container (10), the channel (3) of the valve (5) being connected to the washing liquid supply channel (2). The gas is supplied until the pressure differential between the container (10) and the main line becomes zero. At this moment, the calmed surface (28) of the disk (26) is in the position of a maximum opened section of the throttle valve (12) and the washing liquid supply valve (6). The pressure is relieved from the container (10) and the container (10) is filled with the washing liquid at a maximum rate. When the container (10) is overfilled, the washing liquid is discharged into the drainage channel (13) and the entire pouring system of the automatic device is washed. When the washing is finished, the throttle valve (12) and the washing liquid supply valve (6) are fully closed. Subsequently, the throttle valve (12) is opened again and reduces the pressure in the container (10) (with the washing liquid supply valve (6) being closed) to the atmospheric pressure. When the pressure is equalized to the atmospheric pressure, the disk (26) having the cammed surface (28) is in the position of relieving the pressure from the cavity (18), the spring (19) returns the piston (17) into its starting upper position, the neck of the container (10) is released from clamping and is removed from the fork (35).
It follows from the foregoing description that as a result of the valves of the flow switch being provided with a single common electromechanical cam drive, an increased compactness, a simplified design of the automatic device and an improved maintainability thereof are achieved.
