Description

 The invention relates to the automatic filling of liquids in bottles, is used in enterprises for the production of beverages, alcoholic beverages, etc.

 Known are mechanical machines of the linear rotary type, for example, those that are part of the packaging-closing lines for liquid products, containing a fixed number of dosing and capping cartridges and a rigid mechanical connection between them, as a result of which the machine cannot be changed to bottles of different sizes and doses, and the productivity changed within narrow limits. The range of productivity change can be increased in the device, reconfiguration to a different bottle size is allowed, however, the possibility of dispensing liquid is not provided. In this device, adopted as a prototype, it is possible to change the number of capping cartridges and fixing the bottle relative to the cartridges. Disadvantages: lack of dosage and mixing of liquids, reconfiguration of the bottle fixing unit, synchronization of machine components.

 The proposed device is devoid of the described disadvantages, allows you to expand the scope and technical capabilities of the machine. This is achieved due to the fact that the machine is equipped with a device for collecting, cutting off and dispensing doses of liquid, counting-fixing units for bottles, locking units for individual parts of the machine, synchronizing its operation with a wide range of productivity changes. The presence of more than one metering device allows for the blending (mixing) of media.

 Salient features of the invention: several (more than one) dosing serial devices with independent dose changes, the presence of two counting-fixing nodes located on a common bottle conveyor, the synchronization unit of the individual nodes.

 The drawing shows the proposed machine.

 The machine contains: a bottle conveyor 1 with a movable belt (plates) 2, dosing cups 3, a fluid supply manifold 4 and outlet pipes 5, a locking device 6, a constant level vessel 7, a filling unit 8 drive with a traverse 9 and outlet fittings 10; counting-fixing filling unit: sprocket 11, latch 12, sensor 13; cork supply device 14, a capping unit with a drive 15 and cartridges 16, a counting-fixing capping unit with an asterisk 17, a latch 18 and a sensor 19, position sensors of the capping cartridge 20, the control unit 21, the sensors for the presence of bottles 22 and the conveyor drive 23.

 The operation of the device is as follows.

 Empty bottles are conveyed through conveyor 1 from left to right and go to the counting-fixing filling unit, rotating asterisk 11. The latter rotates by a certain angle by each bottle (the angle of rotation is determined by the number of rays of the asterisk) and is fixed by catch 12 when such a quantity of bottles is adjusted automatic, namely, the number equal to the number of dispensing cups 3. In the depicted embodiment, three glasses, however, you can set a different number of glasses, as shown, for example, by a dotted line. Upon receipt of a given number of bottles, the latch 12 fixes the sprocket 11, stopping all the bottles following the back. After fixing, the sensor 13 is activated, and the control unit 21 gives the command to the drive 8. The latter closes the feed manifold 4 with the shutoff body 6 and lowers the crosshead 9 with filler nipples 10 into the bottles. In this case, the flexible hoses connecting the outlet pipes 5 to the outlet fittings 10 are straightened, and the doses of liquid collected in the glasses 3 are poured into the bottles. At the end of the drain, the control unit 21 gives a command to the drive 8, which raises the yoke 9 with fittings 10 (thereby locking the discharge of liquid from the glasses 3) and simultaneously opens the shut-off member 6, after which the set of new doses in the glasses 3 begins. the drive 8, the latch 12 releases the sprocket 11, and the bottles, moved by the conveyor 1, are moved to the capping unit. Passing under the device 14, the bottle with its whisk falls into the next closure cap and carries it on its throat. Next, the bottle approaches the sprocket 17, turns it one step (corresponding to the number of rays of the sprocket). In this case, the latch 18 activates, fixing the bottle under the capping cartridge 16. When setting the machine for two or more capping cartridges (shown by a dotted line), the asterisk 17 and the latch 18 fix two or more bottles, respectively. After fixing the bottle, the sensor 19 is activated, and the control unit 21 gives a command to the actuator 15, which lowers the capping cartridge 16 onto the bottle, capping it. After that, the drive 15 raises the cartridge 16 and mechanically disconnects the latch 18. The latter releases the sprocket 17, and the corked bottle is carried along the conveyor further, freeing up space for the next bottle. The cycle of the machine is repeated.

 The sensors for the presence of bottles 22 perform the following functions: provide an enable signal to block 21 and drive 8 when the required number of bottles is available in front of the filling unit (no less than the number of pouring glasses), block the operation of the filling unit when the conveyor overflows after this node, block the operation of the entire machine when the conveyor overflows after the machine.

Device Advantages:
ease of implementation due to the exclusion of carousel nodes and complex kinematic relationships;
the possibility of reconfiguring to different sizes of bottles due to the displacement along the height of the bottling and capping units and the configuration of the rays of the stars 11 and 17;
the ability to change the dose due to the individual settings of each dosing cup 3 (by moving along the height of the air tube);
the possibility of blending in a bottle with a dosage of each component by sequential bottling of each component;
a large range of changes in the productivity of the machine due to a change in the number of dispensing cups and capping cartridges, as well as a variable feed rate for the bottles by the conveyor;
flexible synchronization of individual nodes of the machine due to the common control unit, which allows you to change the speed of the separate filling and corking nodes to coordinate their performance and exclude both the conveyor overflow and the lack of bottles in front of each machine.

 A prototype filling machine is manufactured and tested with positive results.
