Description

The invention relates to the field of food industry, in particular to commercial equipment, and can be used for dispensing beer and other foaming and / or carbonated drinks from an isobaric container into plastic, for example, polyethylene terephthalate (PET) bottles in retail kiosks, in stores, restaurants and bars.

Known mechanisms for fastening the neck of the bottle to the open end of the drain channel of the device for filling foaming and / or carbonated drinks, implemented in many automated lines (US patent No. 6601618, IPC B 67 C 3/06, publ. 05.08.2003; US patent No. 6192946, IPC B 65 V 1/04, publ. 02/27/2001, Australian patent No. 491145, IPC B 3 3/10, 3/06, publ. 1978; Wolfgang Kunze. Technology of malt and beer .- C Petersburg, Profession, 2001.- pp. 566-567; Technological equipment of canneries.- M, 1986.- p. 418-419), each of which contains an elastic ring seal, tanovlenii in an end face of the drain channel, a table for placing the bottle in alignment drain channel and a mechanism of axial movement of the bottle with a table for pressing the bottle neck end to the annular elastic seal end downcomer apparatus for dispensing of foaming and / or carbonated beverages.

The disadvantage of such designs is the impossibility of fixing the plastic bottle to the end of the drain channel of the device for dispensing foaming and / or carbonated drinks due to insufficient stiffness of the specified plastic bottle.

There is a known mechanism for attaching the neck of a plastic bottle to an automatic liquid dispensing device (RF patent No. 2060926, IPC B 67 C 3/04, publ. 05.27.1996), including an o-ring installed at the end of the drain channel and spring-loaded plastic neck grips located there bottles connected by curly swivel brackets with drive rods of the specified mechanism.

However, the specified mechanism for attaching the neck of a plastic bottle to the end of the drain channel is used in production lines for filling liquid, has a rather complicated structure, which cannot be used in devices for manual liquid filling.

The closest analogue (prototype) is the mechanism for attaching the neck of a plastic bottle to the drain channel of a device for manually filling foaming and / or carbonated drinks, comprising a hollow body with a control handle located around the wall of the drain channel with the possibility of rotation and axial reciprocating movement and a spoon with a groove corresponding to the size of the neck of the PET bottle, attached to the body and installed in front of the open end of the drain channel having an elastic ring seal, respectively according to the diameter of the neck of the PET bottle. The case of the mechanism is kinematically connected to the wall of the drain channel by a bayonet connection. The bayonet connection is a blind screw groove made in the wall of the drain channel, in which there is an axis with a roller attached to the housing of the fastening mechanism of the neck of a plastic bottle (RF patent for utility model No. 36370, IPC Β67Ό 1/06, published on March 10, 2004 .).

The disadvantage of this mechanism is that during the clamping of the PET bottle, when turning the control knob, the PET bottle held by the operator’s hand rotates together with the mechanism body and spoon, which reduces the usability of the mechanism. In addition, the mechanism allows you to clamp PET bottles of only one neck height, which narrows the scope of its application.

The technical result of the invention is to improve the usability of the mechanism and the possibility of attaching PET bottles with different neck heights.

The specified technical result is achieved by the fact that the mechanism of fastening the neck of the plastic bottle to the drain channel of the device for manual filling of foaming and / or carbonated drinks contains a hollow body with a control handle located around the wall of the drain channel with the possibility of rotation and a spoon with a groove corresponding to the size of the neck of PET- a bottle mounted with the possibility of axial reciprocating movement in front of the open end of the drain channel having an elastic ring seal corresponding to the diameter of the neck of the PET bottle, according to the invention, it further comprises a hollow cylinder located between the wall of the drain channel and the mechanism body with the possibility of axial reciprocating movement and kinematically connected with the wall of the drain channel by means of a splined element, a spoon with a groove attached to the end of the hollow cylinder, and in a helical slot is made in the wall of the hollow cylinder, in which a roller is mounted, attached by a pin to the housing with a handle. The mechanism has a removable elastic-elastic element, made in the form corresponding to the inner surface of the spoon with a groove, and fixed in the spoon by means of a groove made in it.

The mechanism allows you to quickly and tightly connect the neck of a plastic bottle with the end of the drain channel of a device for manually filling foaming and / or carbonated drinks without rotating the bottle, which together with a spoon performs only reciprocating movement, which increases the convenience of using the mechanism. Without a removable elastic element, the mechanism allows you to attach PET bottles with a long neck. When using a removable elastic element, the mechanism allows filling PET bottles with both short and long necks.

The device is illustrated by the following graphic materials.

In FIG. 1 is a diagram of a device for manually filling foaming and / or carbonated drinks with a plastic bottle fastening mechanism. In FIG. 2 is a view A of FIG. 1, which shows a local section of the fastening mechanism of the neck of a plastic bottle. In FIG. 3 shows a section along BB of FIG. 1. FIG. 4 shows a hollow cylinder with a spoon in a section.

A device for manual bottling of a drink with a counter-pressure in PET bottles contains (Fig. 1 and 2) a housing 1 mounted, for example, on a stand (not shown in the drawings), in the body of which there is a supply channel 2 with a fitting 3 for connection with a supply pipe gas from a gas cylinder, a supply channel 4 with a nozzle 5 for connecting to the beverage supply pipe from an isobaric tank, a stepwise axisymmetric cavity 6 formed by a cylindrical wall 7, fixedly attached to the housing 1, open from the bottom end of the housing a 1 and connected to the outlet channel 8 with the supplying gas and drink channels 2 and 4 through a three-way valve 10 installed in the cavity 9 of the body of the housing 1 with a control handle 11 for sequentially connecting one of the supply channels 2 or 4 with the outlet channel 8 or disconnecting all channels in the intermediate position of the control handle 11. The node for extinguishing foam (Fig. 1 and 2) is placed in a stepwise axisymmetric cavity 6 of the housing 1 and is made in the form of a nozzle 12 with an axial through channel 13 and a cylindrical part with a screw drain channel 14 on the outer surface surfaces.

The mechanism for attaching the neck of a plastic bottle to the wall 7 of the drain channel 14 (Figs. 1, 3, and 4) comprises a hollow body 15 with a control handle 16 located rotatably around the wall 7 of the drain channel 14 and a spoon 17 with a groove 18 corresponding to the size of the PET neck - bottles installed with the possibility of axial reciprocating movement in front of the open end of the drain channel 14 having an elastic ring seal 19 corresponding to the neck diameter of the PET bottle. Between the wall 7 of the drain channel and the housing 15 of the mechanism there is a hollow cylinder 20 with the possibility of axial reciprocating movement and kinematically connected with the wall 7 of the drain channel by means of a spline element 21. A spoon 17 with a groove is attached to the end of the hollow cylinder 20, in the wall of which a screw slot is made 22. A roller 23 is placed in the screw slot 22, attached by a pin 24 to the housing 15. The PET bottle fastening mechanism has a removable elastic-elastic element 25 made in a shape corresponding to the inner surface spoons 17 with a groove 18 and mounted in spoon formed therein through bore 26. The throttle valve 27 mounted in the housing 1 and is connected at its inlet with a through axial channel 13 of nozzle 12.

A device for manual filling of foaming and / or carbonated drinks, together with a mechanism for attaching the neck of a plastic bottle to the drain channel, operate as follows. Take a plastic bottle, insert into the groove 18 of the spoon 17 and rotate the handle 16 together with the housing 15. In this case, the roller 23, moving along the screw slot 22, shifts the cylinder 20 with the spoon 17 up. A spoon 17 presses the end of the neck of the PET bottle to the end of the wall 7 of the drain channel 14 and seals them tightly due to the elastic ring element 19 (without turning the PET bottle). When this throttle 27 is closed. The handle 11 of the three-way valve 10 are in a (neutral) vertical position. Then the handle 11 of the three-way valve is deflected by 20 ° (in the opposite direction from the operator). When this channel 2 with gas is communicated through the discharge channel 8, an axisymmetric cavity 6, a screw drain channel 14 with the internal volume of the bottle. In this case, CO ₂ gas from the cylinder enters the bottle, the pressure of which is equalized to the pressure in the isobaric tank. Next, the handle 11 of the three-way valve 10 is tilted 40 ° in the opposite direction. When this channel 4 with the drink is communicated through the discharge channel 8, an axisymmetric cavity 6, a screw drain channel 14 with the internal volume of the PET bottle. Since the pressure in the PET bottle and the isobaric container is the same, there is no flow of beverage into the indicated container. When the throttle 27 is opened, CO2 gas through the axial channel 13, the inlet and outlet channels of the throttle 26 are forced out of the PET bottle into the atmosphere. A pressure differential is created in the isobaric container and the PET bottle, whereby the drink fills the bottle. Passing through the screw drain channel 14, the drink under the action of centrifugal forces is supplied in the form of a conical film onto the walls of the neck of a PET bottle and then flows smoothly along its walls, preventing foaming. The elimination of foaming is also ensured by creating a gas pressure in the filling system and above the surface of the drink in a plastic bottle, which exceeds the saturation pressure of the gas dissolved in the drink. After filling the bottle with a drink to stop its further flow from the isobaric tank, turn the handle 11 of the three-way valve 10 to the neutral (20 degrees) initial vertical position. The remaining gas in the neck of the PET bottle and the partially dissolved gas released from the beverage are removed through the axial channel 13 of the nozzle 12 and the channels of the throttle 27 into the atmosphere. After equalizing the pressure in the PET bottle to atmospheric, rotate the handle 16 in the opposite direction, disconnecting the end of the wall 7 of the drain channel from the neck of the PET bottle, which is removed from the filling device, closed with a stopper and released to the consumer. When filling PET bottles with a short neck, an elastic-elastic element 25 is inserted into the groove 25 of the spoon 17. Further, the mechanism operates as described above.

Thus, the fastening mechanism allows you to manually quickly and tightly connect the neck of the plastic bottle with the end of the wall of the drain channel of the device for manually filling foaming and / or carbonated drinks without turning the bottle, which significantly increases the usability of the device. The use of a removable elastic-elastic element in the mechanism allows filling PET bottles with both short and long necks, which expands its functionality.
