Description

Description of the invention

The utility model relates to technology and equipment for packaging liquid products, in particular, chemical reagents, aggressive substances, shampoos, lotions, beer, kvass, wine, soda and other carbonated beverages in containers, in particular, PET and aluminum bottles.

It is known that during the automated filling of some liquid products, one of the conditions for ensuring their high quality and sufficiently long storage periods is the proper sanitary and hygienic treatment of the containers immediately before their filling and the elimination of the possibility of contamination of the liquid product, in a physical, biological and chemical sense, in the process supply of containers to the filling position and the filling itself.

Numerous methods of automated filling of liquids are known, in which the aforementioned operations of the filling process are carried out under controlled atmosphere conditions. For this, for example, a protective atmosphere is formed around the bottling machine by means of its enclosure from the surrounding space, a structure into which inert gas is supplied (see, for example, 05 2005/0188651 AT, IPC B67С3/02, publ. 0О1.09.2005). The disadvantage of such a solution is the bulkiness of the equipment, large losses for the creation of a protective structure, protective gas, the need to reproduce a controlled atmosphere after each, even short-term adjustment or repair, and the need to create proper conditions for the service personnel to stay inside.

The method of automated bottling of drinks according to (05 2005/0126111 JSC, MKV B6583/00, publication date - 06.16.2005) is the closest, in terms of technical essence and set of features, to the proposed one. According to this method, the bottles are rinsed in a special rinsing device immediately before they are fed to the filling station. The filling position, to which the bottles are then brought, is tangential to the carousel rotary device with a vertical axis of rotation. The pouring heads rotate together with the carousel. From the next filling head, which is currently above the filling position, the liquid product is fed into the next container, which is placed in a vertical position under the filling head. In the space 29 around the lower end of the liquid product supply channel and the neck of the bottle entering the /-) position of the start of pouring, a controlled atmosphere is formed by supplying air or other protective gas under pressure. After filling, the bottle is lowered and taken away for further closing.

The volume of the controlled atmosphere chamber in the solution according to (05 2005/0126118) is significantly smaller than the protective structure covering the entire machine according to (05 2005/0188651|. This reduces capital losses and losses of shielding gas and allows service personnel to work in normal conditions without the use of "I special means. But the solution according to (05 2005/0126118) also has inherent shortcomings. The presence of a separately installed rinsing device increases the dimensions of the technological equipment. As follows from the description of the patent and - the drawings, the bottles are in the process of their preparation for filling all the time are in a vertical, bottom-down, o position, i.e. the spillage of rinsing liquid from the middle of the containers is not foreseen, which makes it impossible

Guaranteed elimination of impurities in the product that will be filled with the container. If this operation is still carried out somehow, it requires additional time and necessary means.

The task of the useful model is to create a method of automated filling of liquids: - with increased quality of poured products, due to the guaranteed treatment of containers before their filling; "- with increased productivity of the process of filling liquid products in the container and reduced dimensions of the technological equipment necessary for the implementation of the method, due to: first, providing the opportunity to fill the containers with the liquid product and rinse them with the same means, including

I" poured out the rinsing liquid from the middle of the containers; secondly, isolating only the inner space of the container to be rinsed and filled from the surrounding space, while ensuring the possibility, at the same time, of introducing into the middle of the container and removing the necessary components from it, with guaranteed prevention of contact of the components entering into the middle of the container, with the surrounding environment. o To solve the problem in the method of automated filling of liquids in a container that includes av | rinsing the container, bringing and removing the container to (from) the filling position(s) and filling the container with a liquid product, according to the useful model, before rinsing the container, its neck is fixed to the outlet of the filling head, parallel to it, after which it is inserted into the middle of the rinsing liquid container "iz" 20, removing the rinsing liquid from its middle and filling it with a liquid product, and in the process of rinsing and filling the container, the pouring head together with the container is moved along a curvilinear trajectory, changing the spatial position of the container in such a way that when the rinsing liquid is removed the container would be located upside down, with an angle p of the inclination of its longitudinal axis to the horizontal in the range of 45...902, and when the container is filled with a liquid product, its longitudinal axis would be located at an angle of inclination of 8 to the vertical in the range of 50...1809, s How flows from the mentioned, rinsing of empty containers, including overflow from rinsed containers of liquid, and filling containers with a liquid product, are carried out in one installation of the container, between the operations of bringing the container to the filling position and removing it from the filling position. Instead of controlling when pouring a certain volume of space, larger or smaller, as in the mentioned known solutions, according to the proposed method, only the entrance to the container is isolated from the surrounding environment, and this is done by the element of the pouring head and even before rinsing. This allows not only to reliably prevent the contact of the components fed into the middle of the container with the surrounding environment, but also to introduce all the necessary components into the container and remove them at the same time. This eliminates the need for special means for rinsing the containers before they are filled with a liquid product, for pouring out the rinsing liquid and for feeding the containers from the equipment for rinsing them to the bottling machine: all these operations are carried out on the same equipment as the filling of the containers - at rotation of the container on the carousel between the positions of input to the filling carousel and output from it.

In addition, to improve the quality of processing containers before they are filled with a liquid product, in case

The use of dusty containers, or the first use of containers, after their manufacture by blowing in a mold and storage, in the middle of the containers, in the process or after the supply of rinsing liquid, gas is additionally introduced, for example, compressed air, or carbon dioxide, nitrogen, etc., which intensively sprays the rinsing liquid on the inner surface of the container.

In addition, in order to improve the quality of processing of containers, after removing the rinsing liquid and before 7/0 filling with a liquid product, air or another gas is introduced into their middle to dry the container.

Specialists in the field of bottling liquid products know that the intensity of pin formation when bottling such liquids as beer, wine, kvass, shampoos, lotions, etc. can be reduced, and thus product quality and dosing accuracy - increased, if the liquid is directed into the container in a horizontal direction. It is also known that when the container is placed in a horizontal position, gas losses from the product are much smaller. Therefore, according to the useful model, when finding a container at an angle d of inclination to the vertical within 50...1809, it is filled with a liquid previously saturated with gas.

In addition, simultaneously with filling or after filling the container with a liquid pre-saturated with gas, when the container continues to remain at an angle of inclination 0 to the vertical within 50...1802, saturation gas is additionally injected into its middle.

At the same time, the initial stage of filling the containers with a liquid with active foaming or pre-saturated with gas is most expedient to carry out when the container is located at an angle of 6" to the vertical within 50...1309,

The mentioned characteristic feature of the proposed method makes it particularly effective when pouring beer, wine, shampoos, lotions and other liquid products that foam when filled and when pouring carbonated water, juices and other drinks. what!

In addition, with the mentioned position of the container, it is advisable to saturate the liquids after filling the container by means of an additional short-term pressure effect, the so-called "pneumatic impact", in accordance with my invention application Moa200512624, priority from 12.27.2005.

The proposed method is disclosed in detail below on the example of the description of the design of the machine for t) automated bottling of carbonated water in PET or aluminum bottles and its operation with the help of drawings, where "t on:

Fig. 12, 13 - the beginning of removing the container from the pouring head;

Fig. 14, 15 - sections A-A and B-B, respectively, in a schematic representation, from Fig. 3.

The machine for implementing the proposed method includes a device for bringing containers 1 (Fig. 1) to the pouring position, as part of a winding conveyor 2 and a winding sprocket Z, and a device for removing filled containers from the pouring position, as a part of a removal conveyor 4 and a removal sprocket 5. Sprockets 3, 5 are drive.

Synchronizing sprockets are also installed on the shafts (not marked) on which they are mounted 6. Pouring heads

Sh-7 are installed on the free ends of the spokes 8 of the carousel 9 with a vertical axis of rotation. 20 of them Around the carousel, at a distance from the ends of the spokes, taking into account the length of the containers to be filled, a curved guide 10 is installed. The latter includes the winding part 11 (Fig. 4), which is made flat and sl ascending, i.e., with a rise from the beginning to end, in the direction of rotation of the carousel, and is installed in the place where the container is put on the carousel. After, in the direction of rotation of the carousel, the winding part 11, the guide 10 is made in the form of a steep, convex to the top, arc 12. At the place of removal of the container from the carousel 9, there is a lead 22 part 13 (Fig. 5) of the guide, which is flat and downward, i.e. inclined downward from the beginning to the end, in the direction of rotation of the carousel. Intermediate, between the arc 12 and the end part 13, the curvilinear part 14 of the guide 10 is made, preferably, in the form of an arc in plan, with a smooth decrease in height of its placement in front of the lead-off part 13.

Under the carousel 9 is a clip (not shown) which has as many holes as there are dispensing heads in the 60 machine. It is connected by a system of pipelines (not marked) to the sources of the necessary liquid and, if necessary, gaseous components and is installed with the possibility of rotation around the distributor valve 15.

In the diagram in figure b, the clip and the valve-distributor are conventionally united by the designation "15". Together, they represent a "classic" multi-way cone valve of the spool type. Each technological operation is "served" in a certain sector of the crane. Designs of spools of this kind are well known to specialists and can be used in the proposed machine with simple adjustments, depending on the number of components used in the filling process. Instead of a spool valve, electromagnetic valves and other means known in bottling technology can be used to regulate the supply of liquids and gases.

As for the sources of components necessary for the operation of the machine, in the simplest modification it can be equipped only with a reservoir of a liquid product to be poured, for example, beer, shampoos, lotions and other liquids with active foaming when they are poured (not shown), and a reservoir 16 rinsing liquid. If it is necessary to dry the containers after they have been rinsed, the machine is also equipped with a tank 17 of compressed air. When pouring carbonated liquids, a saturator 18 is additionally connected to the distributor tap 15, and when pouring carbonated liquids with the use of short-term pneumatic influence /o on the liquid (see note on p. 5) - in addition, a cylinder 19 with saturation gas (carbon dioxide , nitrogen, etc.).

The diagram in Fig. 6 corresponds to exactly such a modification of the machine.

Pressure gauges 20 and non-return valves 21 are installed on the pipes (not marked) for connecting tanks 16...19 and the liquid product tank with the distribution valve 15. Pipe 22 is used to remove air from containers 1, and pipe 23 is to release excess gas at equalization of gas pressures in the filled container and the external environment. From the distributor according to the given program, liquid components enter container 1 through pipeline 24 and filling heads 7, and gaseous components - through pipeline 25 and filling heads.

The main part of the pouring head 7 is the barrel 26 (Fig. 7...13), in the middle of which there are two channels in the form of tubes, 27 (Fig. 8) - with a larger diameter, and 28 - with a smaller diameter. The upper ends of the tubes 27, 28 are connected to the pipelines 24, 25, respectively, and their lower ends enter the outlet fitting 29.

At the upper end of the barrel 26, a sleeve 30 is fixed, in the longitudinal hole of which, located at a right angle to the longitudinal axis of the barrel, a finger (not shown) is inserted, fastened to the spoke 8 of the carousel 9.

In the middle, along the length, part of the barrel, on its outer surface, transverse recesses 31 and longitudinal recesses 32 are made. In the same area, there is a clamping clip 33, which is composed of outer 34 and inner З5 bushings. The length of the inner sleeve is much greater than the length of the outer sleeve. Fixing balls 37 are placed in the annular groove of the bushing 34, with the conical part ra", of the bushing 34 and in the corresponding holes (not marked) of the bushing 35, and in the through holes 38 of the bushing 34 and grooves 39 of the bushing 35 - guide balls 40, but supported by screws. plugs 41. The balls 40 also serve to prevent rotation of the barrel 26 and bushings 34 and 35 relative to each other. The outlet fitting 29, to which the lower ends of the tubes 27, 28 are connected, is equipped with an annular seal 44 for sealing the barrel when the neck of the container 1 is connected to it. In the area of the lower end of the barrel, concentric to it, a tubular base 45 of the pouring head is installed. Its lower part protrudes beyond the lower end of the barrel M. In the lower end of the base, a side cutout 46 is made with the formation of a semi-cylindrical projection 47, on the inner surface of which an annular groove 48. The dimensions of the cutout and the groove correspond to the dimensions o c5 of the upper part of the neck of the containers to be filled, so that the upper part of the neck can be inserted into the cutout and be located coaxially with the barrel, and the shoulder 49 of the neck can be inserted into the groove 48 and be clamped in the walls of this hole after the lower end of the barrel is pressed against the neck of the container. Together, these elements of the lower part of the pouring head form a kind of fork for reliable fixation of the empty container relative to the barrel 26, and after this fixation - for moving the container together with the pouring head throughout the entire filling cycle. Nut 50 is used to adjust the degree of sealing of the neck of the container, taking into account the different length of the neck in different types of containers, and screw 51 is used to prevent the nut from turning spontaneously after the aforementioned adjustment is completed. Screw 52) is used to connect sleeve 35 to clamp 33 to the base 44 and preventing them from rotating relative to each other.

To reduce friction during the movement of the sleeve 35 and the base 45 relative to the barrel 26, anti-friction rings 53 are installed in them, and to limit the movement of the sleeve 34 relative to the sleeve 35, a stop ring 54 serves. container 1 will not enter the upward position and will not take its place in the tubular base 45, a safety cover 55 is hinged to the lower end of the last side (Fig. 7. In Fig. 8...13, the cover 55 to simplify the image is conditionally not shown). The shape and dimensions of the cover 55 correspond to the shape and dimensions of the upper part of the containers 1, so that this cover can take the place of the upper part of the container in the middle of the filling head. In addition, protrusions (not shown) are provided on the initial and final parts of the guide 10, when interacting with which the cover sp 55 can be, respectively, inserted and removed from the tubular base(s) 45.

It should also be added that in order to prevent the spillage of liquid from the filling head in the mentioned cases, instead of the cover 55, other known means can be used, capable of blocking the supply of liquid and gas to the filling head or their release from the filling head, for example, so-called loss excess valves .

The proposed method is carried out as follows. Empty containers 1 arrive on the winding conveyor 2 s (Fig. 1, arrow A) to the sprocket 3, which drives the necks of the containers into the cutouts 46 of the filling heads 7, which, together with the carousel 9, rotate in the direction of arrow B. The tubular base 45 of the next filling head is while in the lower position (Fig. 8, 9). Immediately after that, the rollers 43 roll onto the winding part 11 (Fig. 4) of the curved guide 10 and, under the influence of pressure from it, move up the clamping clip 33 together with the balls 37. This movement ends after the balls 37 are in the recesses 31 (Fig. 10, 11). Simultaneously with the outer 34, the inner sleeve 35 moves up with the balls 40, which move into the longitudinal recesses 32 and, thereby, prevent the rotation of the barrel 26 and the sleeves 34 and 35 relative to each other. Since the sleeve 35 is attached to the base 45, the latter also moves together with the neck of the container ev5 upwards, as a result of which the neck of the container is clamped by the fitting 29 in the lower part of the base 45, with the seal 44 simultaneously pressed against it. In this position, the container is ready to be fed into its the middle of the corresponding components.

Immediately after that, the container 1 falls on a similar steep arc, convex to the top, part 12 of the guide 10 (Fig. 1, 2), under the influence of which on the surface of the container, the latter, together with the pouring head, begins to rotate in a vertical plane around the spoke 9 of the carousel 10, which at the same time continues to rotate continuously at a speed that depends on the given performance of the bottling line into which the machine enters. As a result, simultaneously with the rotation relative to the axis 11 of the carousel, the capacity in the middle zone of the part 12 of the guide 10 is in a position at an angle to the vertical and upside down." At the same time, the largest angle to the horizontal is occupied by the capacity in the middle of the part 12 of the guide, at the top of the arc (Fig. 14 ).70 At the same time as the container enters the initial zone of the part 12, rinsing liquid is supplied to its middle from the reservoir 16 through the distributor valve 15, the pipeline 25 and the filling head 7, which after flowing along the walls of the container in the process of its movement along the top of the part 12, is removed from the container through the mentioned means. In the case of using dusty containers, or the first use of containers, after their manufacture by blowing in a mold and burial, into the middle of the containers, after supplying the rinsing liquid, /5 additionally, from the tank 17 or 19 through the tap distributor 15, pipeline 24 and filling head 7 are supplied with gas under a pressure of 2..4 atm, which intensively sprays the rinsing liquid about the inner surface of the container. This gas can be compressed air, or carbon dioxide, nitrogen, etc. After removing the rinsing liquid from the container, compressed air is supplied to the middle to dry the container. Its position between the corners of Fi is optimal for removing the rinsing liquid from the container; Which is equal to 902 to the horizontal, and fo» Which is equal to 452 to the horizontal (Fig. 14).

As the container descends through the descending zone of part 12, i.e., passes a path corresponding to the angle 84 (502), the angle of its axis to the horizontal gradually decreases and the container takes a position horizontal or at a small angle to the horizontal, within the angle 65 , the value of which is equal to 802 (Fig. 15).

At this stage of the process, a liquid product, for example, beer or shampoo, lotion, or other liquids with active foaming, begins to be fed into the middle of the container. As mentioned above, when filling the tank with such fluids in a horizontal position, or at a small angle to the horizontal, foaming is muted.

In case of spilling carbonated liquids, at the same stage, water or other liquid saturated with carbon dioxide or other saturation gas begins to be supplied to the container from the saturator 18. During the filling of the container, the excess saturation gas is removed from the container through the channel 28, the pipeline 24 and the distributor valve 15. at

The flow of the liquid product is regulated due to the back pressure in the pipeline 24 and depends on the speed of rotation of the carousel 9, i.e. the set productivity of the machine. At the same time, the flow of the liquid product is set to 1...595 more than the required volume of the container. Inflow of excess liquid in of the product is limited, accordingly, to a small value of the cross-section of the channel 28 for gas supply/discharge. As a result, the "overflow" of the liquid product is 0.2...1.095, and the filling accuracy is -0.6905.

At the final stage of filling the container with a liquid product, which corresponds to the angle 03 (909), the pouring head cm gradually lowers along the curved guide 10 into a vertical, bottom-down position.

At the moment of completion of filling the container with a liquid product, its remainder is removed through channel 27 and pipeline 25. distribution valve 15, pipeline 24 and channel 28 are fed into the tank under a pressure of 4...wattm in a volume of 20..50cm Z, After 1...bsec, depending on the speed of filling the tank, degree of saturation and properties liquid product, begin equalizing the pressure in the middle of the container with atmospheric pressure.

Regardless of which liquid product the containers are filled with and which method of gas saturation

GI is applied, on the approach to the output sprocket b, the container is gradually, due to the interaction with the guide 12, given a vertical position, with the bottom down." o As can be seen from the above, the part of the trajectory of the containers in which they occupy a horizontal or close to -I horizontal position at movement on the carousel (angle 6", Fig. 15) can be adjusted. The values of the angles are: o; - from the axis of the winding sprocket b to the top of the arc-shaped, convex to the top, part 12 of the guide (Fig. 3); VD. that shk corresponds to the part of the guide , in which the container occupies an upside-down position", and in THAT corresponds to the part of the guide rail, in which the container occupies a horizontal or close to horizontal position, can be adjusted by outlining the parts of the guide 12 depending on the specified process parameters. It is essential that when rinsing the container, its longitudinal axis should be at an angle f to the horizontal, the value of which is within 45...902 (Fig. 14), and when filling with a liquid product, at an angle of 9 to the vertical, the value of which is

Gan borders 50...1802. At the same time, the position of the containers at an angle to the vertical 05 within 90...1309 (Fig. 15) is optimal for the initial stage of filling the containers with liquid products with active foaming or gas-saturated liquids such as soda water and other carbonated drinks.

At the final part of the movement of the container on the carousel 9, immediately in front of the withdrawal sprocket 6, the rollers 60 42 of the next pouring head run under the withdrawal part 13 of the guide 10, under the influence of which the protrusion 36 moves downward, and the balls 37 roll out of the recesses 31. Thus, the sleeve 35 acquires the ability to move down together with the sleeve 34 (Fig. 12, 13). Together with the movement of the clamping clip to the locking ring 54, the container filled with the base 45 is lowered onto the removal conveyor 5 (Fig. 8, 9) and is removed by the sprocket 6 and the conveyor 5 from the machine (arrow B). because if it is necessary to pour into containers of different sizes and shapes, the machine must be equipped with a set of filling heads of different standard sizes.

The proposed method was tested on working mock-ups and on a prototype, the tests of which confirmed the achievement of the mentioned technical result in all the aspects mentioned above. : o (in |Synchronization devices 77711110 32 Longitudinal sealings//-O vespitsyayuret 00000001 External vents 00000000 Animals 0 - 22 | Tube for removing air from the containers and with it 24|Pipeline for supplying liquid components from the distributor tap to the container for 25 Pipeline delivery of gaseous components from the valve of the distributor into the container
