Description

Technical Field

[0001] This invention relates to the field of liquid filling production line structure. Background Technology

[0002] In liquid filling, especially liquor filling, hygiene and efficiency factors need to be considered. Typically, a series of processing equipment such as bottle washing, bottle control, filling, cap removal, capping, and cap sealing need to be arranged in the production line. However, traditional filling machines have limited workload and are difficult to align and have low alignment accuracy, making it difficult to carry out large-scale filling. In particular, when the empty bottle model is changed, traditional filling equipment needs to be replaced with a completely new set of fixtures, which is not very adaptable. Summary of the Invention

[0003] To address the above problems, this invention proposes a fully automatic flexible filling machine that has low alignment difficulty, high alignment accuracy, can perform large-volume filling, and has a wide range of applicable fixtures.

[0004] The technical solution of this invention is as follows: like Figure 1 , 2 As shown, the filling machine 3 includes a filling mechanism 31 and a magnetic levitation conveying mechanism 32; The filling mechanism 31 is located above the filling track 74 and is used to fill the bottles passing below. like Figure 3 , 4 As shown in Figure 5, the magnetic levitation conveying mechanism 32 includes an annular magnetic levitation guide rail 321, a magnetic levitation module 322 fixedly installed inside the magnetic levitation guide rail 321, and several power trolleys 323 inserted into the outer edge of the magnetic levitation guide rail 321. The magnetic levitation guide rail 321 is fixedly installed inside the filling track 74 and is located above the filling track 74. The magnetic levitation guide rail 321 also extends into the area between the dry bottle conveyor belt 73 and the bottle outlet conveyor belt 75. Two pairs of mutually perpendicular magnetic levitation conveyor fingers 324 are fixedly installed on adjacent power trolleys 323. The movement trajectory of the magnetic levitation conveyor fingers 324 passes through the dry bottle conveyor belt, the filling track 74 and the bottle outlet conveyor belt that are connected in sequence. The magnetic levitation module 322 includes track magnetic poles adapted to the magnetic levitation guide rail 321. Several power magnetic poles are fixedly installed on the inner wall of the insertion port of the power trolley 323.

[0005] The filling track 74 is C-shaped, and a guardrail 327 in the same C-shape is fixedly installed on the outside of the filling track 74.

[0006] like Figure 6 , 7As shown in Figures 8 and 9, the filling mechanism 31 includes a material cylinder 311, a mounting support frame 312, a valve lifting mechanism 313, a filling valve mounting plate 314, and multiple filling valves 315. The material cylinder 311 is fixedly mounted on the machine frame via the mounting support frame 312. The filling valve mounting plate 314 is vertically and vertically positioned below the mounting support frame 312 via the valve lifting mechanism 313, and reciprocates under the drive of the valve lifting mechanism 313. The filling valve 315 is fixedly mounted on the filling valve mounting plate 314, with its outlet facing downwards. The inlet of the filling valve 315 is connected to the material cylinder 311 via a flow meter 316 and a wine inlet pipe 317.

[0007] The bottom of the material cylinder 311 is also connected to a wine discharge pipe 318, and a liquid level gauge 319 is installed inside the material cylinder 311.

[0008] The valve lifting mechanism 313 includes a valve lifting motor 3131, a synchronous shaft 3134, two fixed sleeves 3132, and two lifting rods 3133. The housing of the valve lifting motor 3131 is fixedly mounted on the mounting support frame 312, and the output shaft of the valve lifting motor 3131 is connected to the synchronous shaft 3134. The two fixed sleeves 3132 are respectively fixedly mounted on the mounting support frame 312. The lifting rods 3133 pass through the fixed sleeves 3132. The top end of the lifting rods 3133 is connected to a reversing drive mechanism, and the bottom end of the lifting rods 3133 is fixedly connected to the filling valve mounting plate 314. The two reversing drive mechanisms are simultaneously connected to the synchronous shaft 3134.

[0009] The housing of the reversing drive mechanism is fixedly installed on the top of the fixed sleeve 3132. A drive screw is rotatably connected inside the reversing drive mechanism. The drive screw is concentric with the lifting rod 3133. The bottom end of the drive screw passes through the top end of the lifting rod 3133 and is threadedly connected to it. The rotation of the drive screw drives the lifting rod 3133 to rise and fall. The reversing drive mechanism is also provided with a reversing turbine fixedly connected to the drive screw. A reversing worm gear that meshes with the reversing turbine is provided on the synchronous shaft.

[0010] When this invention is in operation, the movement of each motion unit is under the control of magnetic levitation, which significantly improves its motion accuracy, further ensuring the alignment accuracy before filling and reducing the difficulty of alignment. Two adjacent power carriages 323 form one motion unit, allowing for easy adjustment of the distance between the two power carriages within a single motion unit without needing to change the clamps after changing the bottle type. This makes adjustment very convenient and highly adaptable. Furthermore, this invention features two pairs of mutually perpendicular magnetic levitation conveying fingers 324 within each motion unit, which provide more stable clamping and limiting during the bottle pushing process.

Detailed Implementation

[0012] To clearly illustrate the technical features of this patent, the following detailed description is provided through specific embodiments and in conjunction with the accompanying drawings.

[0013] like Figure 1 , 2 As shown, the filling machine 3 includes a filling mechanism 31 and a magnetic levitation conveying mechanism 32; The filling mechanism 31 is located above the filling track 74 and is used to fill the bottles passing below. like Figure 3 , 4 As shown in Figure 5, the magnetic levitation conveying mechanism 32 includes an annular magnetic levitation guide rail 321, a magnetic levitation module 322 fixedly installed inside the magnetic levitation guide rail 321, and several power trolleys 323 inserted into the outer edge of the magnetic levitation guide rail 321. The magnetic levitation guide rail 321 is fixedly installed inside and above the filling track 74, and extends into the area between the dry bottle conveyor belt 73 and the bottle outlet conveyor belt 75. Two pairs of mutually perpendicular magnetic levitation conveyor fingers 324 are fixedly installed on adjacent power trolleys 323. The movement trajectory of the magnetic levitation conveyor fingers 324 passes through the dry bottle conveyor belt, the filling track 74, and the bottle outlet conveyor belt that are connected in sequence. The magnetic levitation module 322 includes track magnetic poles adapted to the magnetic levitation guide rail 321, and several power magnetic poles are fixedly installed on the inner wall of the insertion port of the power trolley 323. During operation, the track magnetic poles and the power magnetic poles cooperate to control several power trolleys 323 to generate magnetic levitation movement. Two power trolleys 323 form a motion unit, and there are a total of 28 power trolleys 323, forming 14 motion units. Among them, 12 motion units are at the filling machine position and 2 motion units are at the top cover position. After filling, the bottles are sequentially driven away from the filling machine by the motion unit and enter the designated capping position. After capping, the motion unit again drives the bottles onto the bottle outlet conveyor belt. Then, the motion unit opens, detaches from the bottles, and the bottle outlet conveyor belt carries the bottles to the next process. At the same time, the motion unit returns to the dry bottle conveyor belt exit position to wait for instructions. Upon receiving a signal, the motion unit once again uses two pairs of magnetic levitation conveyor fingers 324 to stably clamp the bottles and bring them to the filling machine position for filling. This cycle repeats continuously.

[0014] In this way, since the movement of each motion unit is under the control of magnetic levitation, its motion accuracy will be significantly improved, which will further ensure the alignment accuracy before filling and reduce the difficulty of alignment. Two adjacent power carriages 323 form a motion unit, which means that after the empty bottle model is changed, there is no need to change the clamps. Only the distance between the two power carriages in one motion unit needs to be adjusted, which is very convenient and highly adaptable. In addition, this invention has two pairs of mutually perpendicular magnetic levitation conveying fingers 324 in one motion unit, which can play a more stable clamping and limiting role during the pushing of the wine bottle.

[0015] The filling track 74 is C-shaped, and a similarly C-shaped guardrail 327 is fixedly installed on the outer side of the filling track 74. This is to prevent the wine bottles from derailing under extreme circumstances during the transportation of the magnetic levitation conveyor mechanism.

[0016] like Figure 6 , 7As shown in Figures 8 and 9, the filling mechanism 31 includes a material cylinder 311, a mounting support frame 312, a valve lifting mechanism 313, a filling valve mounting plate 314, and multiple filling valves 315. The material cylinder 311 is fixedly mounted on the machine frame via the mounting support frame 312. The filling valve mounting plate 314 is vertically and vertically positioned below the mounting support frame 312 via the valve lifting mechanism 313, and reciprocates under the drive of the valve lifting mechanism 313. The filling valve 315 is fixedly mounted on the filling valve mounting plate 314, with its outlet facing downwards. The inlet of the filling valve 315 is connected to the material cylinder 311 via a flow meter 316 and a wine inlet pipe 317. During operation, the magnetic levitation conveyor positions and transports the bottle to below the filling valve of the filling machine. The bottle is aligned with the center of the filling valve, and then filling begins. The filling metering method can be a mass flow meter, an electromagnetic flow meter, or an electronic magnetic ruler sensor. After the filling volume is reached as set in the program, the filling machine stops working, and the magnetic levitation conveyor transports the filled bottle to the capping position, waiting for the bottle cap to be put on the bottle mouth.

[0017] The bottom of the material cylinder 311 is also connected to a wine discharge pipe 318, and a liquid level gauge 319 is installed inside the material cylinder 311.

[0018] Liquid inlet: The level gauge 319 is installed inside the material tank 311 to detect the liquid level inside the material tank 311. When the level exceeds the set range, the level gauge 319 sends a signal to start or stop liquid inlet, so that the liquid level inside the material tank 311 is kept at a relatively stable height.

[0019] Filling: The inlet of filling valve 315 is connected to flow meter 316, and the inlet of flow meter 316 is connected to material cylinder 311 through inlet pipe 317, forming a filling channel with controllable flow rate. First, the liquid to be filled fills inlet pipe 317, flow meter 316, and filling valve 315. After receiving the filling command, filling valve 315 opens and filling begins. After the set capacity is reached, filling valve 315 closes, completing the filling process.

[0020] Draining: After bottling, if you need to change the bottling type, you need to drain the remaining liquid in tank 311. First, manually connect the drain hose to the outlet of the drain port, then open the drain valve to drain the remaining liquid from the tank. The bottom of the tank has a "U" shaped structure to facilitate liquid drainage and prevent material accumulation.

[0021] The valve lifting mechanism 313 includes a valve lifting motor 3131, a synchronous shaft 3134, two fixed sleeves 3132, and two lifting rods 3133. The housing of the valve lifting motor 3131 is fixedly mounted on the mounting support frame 312, and the output shaft of the valve lifting motor 3131 is connected to the synchronous shaft 3134. The two fixed sleeves 3132 are respectively fixedly mounted on the mounting support frame 312. The lifting rods 3133 pass through the fixed sleeves 3132. The top end of the lifting rods 3133 is connected to a reversing drive mechanism, and the bottom end of the lifting rods 3133 is fixedly connected to the filling valve mounting plate 314. The two reversing drive mechanisms are simultaneously connected to the synchronous shaft 3134. The housing of the reversing drive mechanism is fixedly installed on the top of the fixed sleeve 3132. A drive screw is rotatably connected inside the reversing drive mechanism. The drive screw is concentric with the lifting rod 3133. The bottom end of the drive screw passes through the top end of the lifting rod 3133 and is threadedly connected to it. The rotation of the drive screw drives the lifting rod 3133 to rise and fall. The reversing drive mechanism also has a reversing turbine fixedly connected to the drive screw, and a reversing worm gear meshing with the reversing turbine is provided on the synchronous shaft. In use, the rotation of the valve lifting motor 3131 and the synchronous shaft 3134 will reverse the direction of the drive screw to rotate under the action of the reversing turbine and the reversing worm gear. Then, under the influence of the thread, the lifting rod 3133, which is fixedly connected to the filling valve mounting plate 314, will make a reciprocating lifting and lowering motion. During the movement, the fixed sleeve 3132 fixedly installed on the mounting support frame 312 provides good guidance.

[0022] There are many specific ways to implement this invention. The above description is only a preferred embodiment of this invention. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of this invention, and these improvements should also be considered within the scope of protection of this invention.
