Description

Technical Field

[0001] The present invention relates to the technical field of filling, and in particular to a beer filling device and a use method thereof. Background Art

[0002] Beer filling and capping equipment is a mechanical device specially used in beer production lines. Its main functions include automatically completing beer filling, capping, and related transmission and detection. Such equipment is usually integrated together to form a complete production line.

[0003] A filling and capping machine is disclosed in the patent publication number CN113044783A, which belongs to the technical field of capping equipment. The filling and capping machine includes a conveying device, a filling device and a capping device arranged on a base for conveying bottles; the filling device ensures the filling accuracy through a metering cylinder, and the capping device ensures the stability of conveying bottle caps through an oscillator.

[0004] The prior art has the following defects:

[0005] The current dairy and beverage filling and capping production lines on the market usually include two key processes: filling and capping. Traditional filling and capping machines rely on conveyor belts to transfer workpieces. In this process, the workpiece is first filled with liquid through the filling process, and then the cap is tightened in the capping process. In the traditional filling method, filling and capping are divided into two processes. The movement of the bottle between the two stations will cause the wine to shake, and the gas in the wine will be partially discharged, affecting the taste. In addition, the movement of the wine bottle between the two stations increases the time for the gas in the wine to be released. Summary of the invention

[0006] In view of the above problems in the prior art, a beer filling device and a method for using the same are proposed.

[0007] One aspect of the present application provides a beer filling device, the purpose of which is to combine the two major processes of filling and capping, so that the beer can be packaged immediately after the filling is completed, reduce the contact between beer and air, prevent oxidation, maintain the carbonation content of the beer, improve production efficiency and reduce the risk of microbial contamination.

[0008] The technical solution of the present invention is: a beer filling device, including a bottle, and also including:

[0009] Bottle cap output mechanism, used for arranging and outputting bottle caps;

[0010] The filling mechanism is arranged above the wine bottle and is used for filling the wine. The filling mechanism comprises a shell and a filling needle arranged in the shell. The shell moves vertically through the cylinder.

[0011] The sealing platform is tilted above the wine bottle and is used to carry the bottle cap. A slide rail is connected between the bottle cap output mechanism and the sealing platform. The bottle cap in the sealing position is located directly above the bottle mouth of the wine bottle. The edge of the bottle cap is tilted and overlapped with the edge of the bottle mouth of the wine bottle. During the filling, the filling needle passes through the sealing platform and rests against the inner wall of the bottle mouth.

[0012] A capping mechanism, which is arranged on the packaging platform and connected to the housing, and is used to press the bottle cap tightly onto the bottle mouth of the wine bottle;

[0013] The material discharge mechanism is arranged on the packaging platform and connected to the shell, and is used for individually releasing the bottle caps in the slide rail to the packaging position.

[0014] By adopting the above scheme, the two major processes of filling and capping are combined together by arranging a filling mechanism, a packaging platform, a capping mechanism and a discharge mechanism. The filling mechanism performs a downward and upward movement during the filling process. During this process, the filling mechanism drives the pressing plate to rotate, and the pressing plate drives the capping member to press the bottle cap in the packaging position onto the bottle mouth to seal it with the bottle mouth. At the same time, the lifting of the filling mechanism drives the U-shaped frame to rotate, and the blocking bar releases the next bottle cap to slide to the packaging position. This device connects the filling and capping closely, and the filling is immediately sealed after the filling is completed, which avoids the gas overflow in the wine to the greatest extent, reduces microbial contamination, and ensures the taste and quality of the wine.

[0015] Furthermore, a capping hole is provided on the bottom surface of the packaging platform, the bottle cap in the packaging position is arranged above the capping hole, the edge of the capping hole is slightly smaller than the diameter of the bottle cap, and the filling needle passes through the capping hole during filling.

[0016] By adopting the above scheme, a sealing platform is set up to position the bottle cap to be pressed above the wine bottle, as close to the bottle mouth as possible, and the bottle cap is immediately pressed and sealed after the filling is completed to minimize the leakage of gas in the wine.

[0017] Furthermore, the capping mechanism includes a capping member arranged above the bottle cap, side plates symmetrically arranged on both sides of the packaging platform, and a pressure plate rotatably arranged between a pair of side plates, one end of the pressure plate is fixedly connected to the capping member, and the other end is hinged to the outer shell through a plurality of connecting rods hinged in sequence.

[0018] By adopting the above scheme, the capping mechanism drives the capping member to press and seal the bottle mouth when the filling mechanism moves upward after filling.

[0019] Furthermore, the discharge mechanism includes a support bolt arranged on the side of the packaging platform, a U-shaped frame rotatably arranged on the support bolt, and a torsion spring sleeved on the support bolt, the torsion spring connects the support bolt and the U-shaped frame, and cross bars are respectively arranged at both ends of the U-shaped frame, and the cross bars extend to the front and rear sides of the next bottle cap to be packaged, and blocking bars are arranged on the two cross bars, and only one of the blocking bars is in a position to block the bottle cap from sliding down, and one end of the U-shaped frame is hinged to the outer shell through a plurality of connecting rods 2 that are hinged in sequence.

[0020] By adopting the above scheme, through the discharge mechanism, the two blocking bars alternately block the bottle caps from sliding down, and when the filling mechanism finishes filling and moves upward, it drives the U-shaped frame to swing once, the blocking bar close to the lower side releases the bottle cap, and the blocking bar close to the upper side blocks the next bottle cap, and the U-shaped frame releases one bottle cap to the packaging position each time it swings.

[0021] Furthermore, the side plate is provided with a matching hole for the cross bar to swing.

[0022] By adopting the above solution, a swinging space is provided for the crossbar by setting the matching holes.

[0023] Furthermore, the bottle cap output mechanism includes a bottle cap storage barrel, a rotating disk arranged at the bottom of the bottle cap storage barrel, a driving motor arranged at the bottom of the rotating disk, a plurality of storage troughs arranged at the edge of the rotating disk, and a storage bin arranged in the bottle cap storage barrel, the bottom of the storage bin is connected to the storage trough, and the storage bin is connected to the slide rail.

[0024] By adopting the above scheme, the bottle cap output mechanism is used to make multiple bottle caps in the bottle cap storage barrel fall into the storage trough in turn, be transported to the storage bin through the rotation of the storage trough, and then slide to the packaging platform in turn through the slide rail.

[0025] Furthermore, a vibrator is provided at the bottom of the bottle cap storage barrel.

[0026] By adopting the above scheme and arranging a vibrator, it is convenient for the bottle caps in the bottle cap storage barrel to fall into the storage trough.

[0027] Another aspect of the present invention provides a method for using a beer filling device, comprising the following steps:

[0028] Step 1: Before filling, the wine bottles are cleaned and sterilized, and the cleaned wine bottles are sent to the bottom of the packaging platform through the conveyor belt;

[0029] Step 2: The bottle cap output mechanism takes the bottle caps out of the bottle cap storage barrel and slides them into the slide rail by gravity. The packaging platform accurately positions the bottle caps at the packaging position to facilitate subsequent packaging operations. The remaining bottle caps are blocked by the discharge mechanism.

[0030] Step 3: Start the cylinder to move the filling mechanism downward, and the filling mechanism injects beer into the bottle through the filling needle. This process controls the flow rate and filling volume of the beer to avoid excessive foam and overflow;

[0031] Step 4: Start the cylinder to move the filling mechanism upward. During the process of lifting the filling mechanism upward, the pressing plate is driven to rotate. The pressing plate drives the capping member to press the bottle cap in the packaging position onto the bottle mouth to seal it with the bottle mouth. At the same time, the lifting of the filling mechanism drives the U-shaped frame to rotate, and the blocking bar releases the next bottle cap to slide to the packaging position;

[0032] Step 5: After the capping is completed, the system will test the tightness of the cap, and the qualified wine bottles will be output to the packaging process through the discharge mechanism.

[0033] By adopting the above solution, the beer can be packaged immediately after filling, which can better protect the quality, taste and stability of the beer, and also improve the production efficiency and the hygiene and safety of the product.

[0034] Beneficial effects of the present invention:

[0035] The two major processes of filling and capping are combined together by setting a filling mechanism, a sealing platform, a capping mechanism and a discharge mechanism. The filling mechanism moves down and up during the filling process. During this process, the filling mechanism drives the pressing plate to rotate, and the pressing plate drives the capping piece to press the bottle cap in the sealing position onto the bottle mouth to seal it with the bottle mouth. At the same time, the lifting of the filling mechanism drives the U-shaped frame to rotate, and the blocking bar releases the next bottle cap to slide to the sealing position. This device connects the filling and capping closely, and the filling is immediately sealed after the filling is completed, which avoids the gas overflow in the wine to the greatest extent, reduces microbial contamination, and ensures the taste and quality of the wine.

[0047] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0048] Example 1, reference Figure 1-9 , which is the first embodiment of the present invention, provides a beer filling device, including a wine bottle 1, and also includes a bottle cap output mechanism 2 for arranging and outputting bottle caps 3; a filling mechanism 4, which is arranged above the wine bottle 1 and is used to fill the wine, the filling mechanism 4 includes a shell 5 and a filling needle 6 arranged in the shell 5, and the shell 5 moves vertically through a cylinder; a packaging platform 7, which is tilted and arranged above the wine bottle 1, and is used to carry the bottle cap 3, and a slide rail 8 is connected between the bottle cap output mechanism 2 and the packaging platform 7, the bottle cap 3 in the packaging position is located directly above the bottle mouth of the wine bottle 1, and the edge of the bottle cap 3 is tilted and overlapped on the edge of the bottle mouth of the wine bottle 1, and the filling needle 6 passes through the packaging platform 7 and leans against the inner wall of the bottle mouth during filling; a capping mechanism 9, which is arranged on the packaging platform 7 and connected to the shell 5, and is used to press the bottle cap 3 at the bottle mouth of the wine bottle 1; a discharging mechanism 10, which is arranged on the packaging platform 7 and connected to the shell 5, and is used to release the bottle cap 3 in the slide rail 8 to the packaging position individually.

[0049] Specifically, the wine bottle 1 is set on a conveyor belt (not shown in the figure), which transports the wine bottle 1 to the bottom of the packaging platform 7 and then pauses. After completing the filling and packaging, it continues to move until the next wine bottle 1 enters the work station; the cylinder (not shown in the figure) is connected to the shell 5, and is used to control the up and down movement of the filling mechanism 4; the slide rail 8 is four steel cables, and the bottle cap 3 slides in the four steel cables. The four steel cables are bent 180° to turn the bottle cap 3 over; the filling needle is against the inner wall of the bottle mouth. This process requires precise control of the flow rate and filling volume of the beer to avoid excessive foam and overflow. During the beer filling process, the filling tube is placed close to the inner wall of the bottle mouth, and the beer can flow slowly along the bottle wall, reducing the violent stirring of the beer, thereby effectively reducing the generation of foam. Reducing foam helps to increase the filling speed, because too much foam in the bottle may cause overflow or require extra time to wait for the foam to dissipate, thereby improving the filling efficiency, while reducing the contact between the beer and the air during filling, reducing the amount of oxygen mixed in, and effectively preventing the beer from oxidizing, maintaining the flavor and shelf life of the beer.

[0050] The two major processes of filling and capping are combined together by arranging the filling mechanism 4, the packaging platform 7, the capping mechanism 9 and the discharge mechanism 10. The filling mechanism 4 performs a downward and upward movement during the filling process. During this process, the filling mechanism 4 drives the pressing plate 14 to rotate, and the pressing plate 14 drives the capping member 12 to press the bottle cap 3 in the packaging position onto the bottle mouth to seal it with the bottle mouth. At the same time, the lifting of the filling mechanism 4 drives the U-shaped frame 17 to rotate, and the blocking bar 20 releases the next bottle cap 3 to slide to the packaging position. This device connects the filling and capping closely, and the filling is immediately sealed after the filling is completed, so as to avoid the gas overflow in the wine body to the greatest extent, reduce microbial contamination, and ensure the taste and quality of the wine body.

[0051] Reference Figure 5 A capping hole 11 is provided on the bottom surface of the packaging platform 7, and the bottle cap 3 in the packaging position is arranged above the capping hole 11. The edge of the capping hole 11 is slightly smaller than the diameter of the bottle cap 3. During perfusion, the perfusion needle 6 passes through the capping hole 11.

[0052] Specifically, the bottle cap 3 is in a tilted state when in the sealing position. During filling, the filling needle 6 passes through the capping hole 11, and the filling needle 6 is inserted from the gap between the bottle cap 3 and the bottle mouth. The bottle mouth is in a semi-shielded state, which can maximize the escape of gas in the wine bottle 1 and prevent microorganisms from falling into the bottle mouth.

[0053] By setting up the packaging platform 7, the bottle cap 3 to be pressed is positioned above the wine bottle 1, as close to the bottle mouth as possible, and the bottle cap is immediately pressed and sealed after the filling is completed, so as to avoid the gas in the wine body from overflowing to the greatest extent.

[0054] Reference Figure 1 and Figure 7-Figure 8The capping mechanism 9 includes a capping member 12 arranged above the bottle cap 3, side plates 13 symmetrically arranged on both sides of the packaging platform 7, and a pressing plate 14 rotatably arranged between a pair of side plates 13. One end of the pressing plate 14 is fixedly connected to the capping member 12, and the other end is hinged to the shell 5 through a plurality of connecting rods 15 hinged in sequence.

[0055] Specifically, the pressing plate 14 is in an "L" shape. Two rotating ears are symmetrically arranged at the bending part of the pressing plate 14, and the rotating ears are rotatably connected between a pair of side plates 13 through a support shaft. The pressing plate 14 is fixedly connected to the edge of the capping member 12. The number of connecting rods 15 can be two, three or even more, and multiple connecting rods 15 are hingedly connected in sequence. When the filling mechanism 4 is lifted to the highest position, multiple connecting rods 15 are straightened by the shell 5, and the connecting rods 15 hinged to the pressing plate 14 pull the pressing plate 14 to rotate around the support shaft, and the pressing plate 14 drives the capping member 12 to rotate, and the capping member 12 squeezes the bottle cap 3 through the capping hole 11 and presses it on the bottle mouth.

[0056] Through the capping mechanism 9, when the filling mechanism 4 moves upward after filling, the capping member 12 is driven to press and seal the bottle mouth.

The torsion spring 18 connects the support bolt 16 and the U-shaped frame 17. Both ends of the U-shaped frame 17 are respectively provided with cross bars 19, and the cross bars 19 extend to the front and rear sides of the next bottle cap 3 to be packaged. Blocking bars 20 are arranged on the two cross bars 19, and only one blocking bar 20 is in a position to block the bottle cap 3 from sliding down. One end of the U-shaped frame 17 is hinged to the shell 5 through a plurality of connecting rods 21 hinged in sequence.

[0058] Specifically, the U-shaped frame 17, the two cross bars 19, and the two blocking bars 20 are fixedly connected in sequence, the two blocking bars 20 rotate around the supporting bolts 16, the torsion springs 18 are used to reset the positions of the blocking bars 20, the number of connecting rods 21 can be two, three or even more, and the multiple connecting rods 21 are hingedly connected in sequence. When the perfusion mechanism 4 is perfusing, the blocking bar 20 on the lower side is in the blocking position, and the blocking bar 20 on the upper side is in the releasing position. When the perfusion mechanism 4 finishes perfusing and moves upward, and the perfusion mechanism 4 is lifted to the highest position, the multiple connecting rods 21 are straightened by the shell 5, and the connecting rod 21 hinged to the U-shaped frame 17 pulls the U-shaped frame 17 to rotate, so that the blocking bar 20 on the lower side is in the releasing position, and the blocking bar 20 on the upper side is in the blocking position, so that the bottle cap 3 on the lower side slides to the sealing position.

[0059] Through the discharge mechanism 10, the two blocking bars 20 alternately block the bottle caps 3 from sliding down. When the filling mechanism 4 finishes filling and moves upward, it drives the U-shaped frame 17 to swing once. The blocking bar 20 close to the lower side releases the bottle cap 3, and the blocking bar 20 close to the upper side blocks the next bottle cap 3. The U-shaped frame 17 releases one bottle cap 3 to the packaging position each time it swings.

[0062] Reference Figure 2-Figure 3 The bottle cap output mechanism 2 includes a bottle cap storage barrel 23, a rotating disk 24 arranged at the bottom of the bottle cap storage barrel 23, a driving motor 25 arranged at the bottom of the rotating disk 24, a plurality of storage troughs 26 arranged at the edge of the rotating disk 24, and a storage bin 27 arranged in the bottle cap storage barrel 23, the bottom of the storage bin 27 is connected to the storage trough 26, and the storage bin 27 is connected to the slide rail 8.

[0063] Specifically, a plurality of material storage troughs 26 are equidistantly distributed on the edge of the rotating disk 24, a material storage bin 27 is arranged on the rotating path of the material storage trough 26, the bottom of the material storage bin 27 is flush with the upper end surface of the rotating disk 24, and a vibrator is also arranged on the bottle cap storage barrel 23, so that the bottom surface of the bottle cap 3 falls into the material storage trough 26 with the bottom surface facing downward through vibration and rotation, and after turning 180° in the slide rail 8, the top surface of the bottle cap 3 slides into the packaging platform 7 with the top surface facing upward.

[0064] Through the bottle cap output mechanism 2, the multiple bottle caps 3 in the bottle cap storage barrel 23 are dropped into the storage trough 26 in sequence, and are rotated and transported to the storage bin 27 through the storage trough 26, and then slide to the packaging platform 7 in sequence through the slide rail 8.

[0065] Example 2, reference Figure 1-9 , which is a second embodiment of the present invention, provides: a method for using a beer filling device, using the beer filling device, comprising the following steps:

[0066] Step 1: Before filling, the wine bottles 1 are cleaned and sterilized, and the cleaned wine bottles 1 are sent to the bottom of the packaging platform 7 by a conveyor belt;

[0067] Step 2: The bottle cap output mechanism 2 takes out the bottle caps 3 from the bottle cap storage barrel 23 and slides them into the slide rail 8 by gravity.

The remaining bottle caps 3 are blocked by the discharging mechanism 10.

[0068] Step 3: Start the cylinder to move the filling mechanism 4 downward, and the filling mechanism 4 injects beer into the bottle 1 through the filling needle. This process controls the flow rate and filling volume of the beer to avoid excessive foam and overflow;

[0069] Step 4: Start the cylinder to move the filling mechanism 4 upward. During the lifting process of the filling mechanism 4, the pressing plate 14 is driven to rotate.

At the same time, the lifting of the filling mechanism 4 drives the U-shaped frame 17 to rotate, and the blocking bar 20 releases the next bottle cap 3 to slide to the sealing position;

[0070] Step 5: After the capping is completed, the system will test the tightness of the cap, and the wine bottles 1 that pass the test will be output to the packaging process through the discharge mechanism 10.
