[0002] Bottles are containers used to hold liquid products and are widely used in the food, beverage, and pharmaceutical industries. For example, coconut water is often packaged in transparent PET bottles. PET bottles offer advantages such as light weight, high strength, excellent transparency, and are non-toxic and odorless. They facilitate easy inspection of the product and effectively protect its quality. Bottles come in a variety of sizes, tailored to the product's capacity, and in a variety of shapes, including round and square, to suit diverse packaging and display needs.

[0003] The coconut water bottling process is rigorous and complex. In the current process, bottle quality inspection is performed after the transfer process, relying on a separate inspection station using vacuum decay seal detectors or visual inspection systems.

[0023] In order to better understand the technical content of the present invention, a specific embodiment is provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0024] See also Figures 1 to 4 The present invention provides a filling bottle 14 transfer device with an automatic detection function, comprising a frame 1, a first conveyor belt 13, a bracket 16, a second conveyor belt 17 and a controller 20. The first conveyor belt 13 is arranged at the bottom of the frame 1, and a plurality of filling bottles 14 are arranged in an array on its top surface.

[0025] When the transfer device is working, first start the first conveyor belt 13 to transfer the filling bottle 14 to the predetermined position, start the moving mechanism, and the moving mechanism drives the first hydraulic rod 8 to move. The movement of the first hydraulic rod 8 drives the shell 12 to be located directly above the filling bottle 14, and its circular groove is opposite to the filling bottle 14. Then start the first hydraulic rod 8, and its telescopic end extends to drive the shell 12 to descend to a predetermined height. Then start the second hydraulic rod 25, and the telescopic end of the second hydraulic rod 25 descends to drive the positioning mechanism to enter the appropriate position from the bottle mouth of the filling bottle 14. Start the positioning mechanism to position and fix the filling bottle 14, and then start the second hydraulic rod 25. The telescopic end of the second hydraulic rod 25 shortens to drive the filling bottle 14 to rise. At this time, start the air pump 11, open the first solenoid valve 9 and the second solenoid valve 19, and the air pump 11 passes air through the pressure pipe 10 and the connecting pipe 18. The air is ejected from the bottom of the channel 34, thereby blowing and cleaning the inside of the filling bottle 14 to improve the cleanliness of the filling bottle 14. Continue to lift the filling bottle 14 to make it enter the circular groove. When the top surface of the bottle mouth of the filling bottle 14 abuts against the top surface of the circular groove, stop the second hydraulic rod 25 and start the pressure sensor 30 to detect the air pressure inside the filling bottle 14. When the pressure sensor 30 detects the predetermined pressure value, stop the air compressor and close the first solenoid valve 9 and the second solenoid valve 19 to maintain the pressure of the filling bottle 14. After the preset time, when the pressure reduction amplitude meets the predetermined range, it is determined that the seal is qualified and the filling bottle 14 has no penetrating damage; when the pressure reduction amplitude exceeds the range, it is determined that the seal is unqualified and the filling bottle 14 has penetrating damage; after completing the sealing test, start the shaping mechanism to fill the qualified seal The bottle 14 is shaped, thereby automatically completing the inspection of the filled bottle 14; after completing the inspection operation, the moving mechanism is started, and the moving mechanism drives the shell 12 to move to the side of the first conveyor belt 13, and then the positioning mechanism is started to release the filled bottle 14 with unqualified sealing, so that it is separated from the circular groove, and then the moving mechanism is started again, and the moving mechanism drives the shell 12 to move to just above the second conveyor belt 17, and then the positioning mechanism is started to release the filled bottle 14 with qualified sealing, so that it is placed on the second conveyor belt 17, thereby realizing the transfer of the filled bottle 14 and automatically completing the sealing inspection and shaping, and separating the filled bottle 14 with unqualified sealing. The transfer device has a high degree of integration and reduces production costs.

[0026] Preferably, the moving mechanism includes a first screw rod 2, a first motor 3, a U-shaped slide 4, a second screw rod 5, a moving block 7 and a second motor 6. The first screw rod 2 is rotatably arranged at the top of the frame 1, one end of which is rotatably connected to the frame 1, and the other end passes through the frame 1 and is driven to the first motor 3. The first motor 3 is arranged on the side of the frame 1. The U-shaped slide 4 is arranged on the first screw rod 2 and is slidably connected to the top of the frame 1. The second screw rod 5 is rotatably arranged at the top of the U-shaped slide 4, one end of which is rotatably connected to the U-shaped slide 4, and the other end passes through the U-shaped slide 4 and is driven to the second motor 6. The second motor 6 is arranged on the side of the frame 1.

[0027] The moving mechanism is used to transfer the first hydraulic rod 8. When the moving mechanism is working, the first motor 3 is started first. The first motor 3 drives the first screw rod 2 to rotate, driving the U-shaped slide 4 to slide horizontally along the top of the frame 1, thereby realizing the positioning of the first hydraulic rod 8 in the axial direction of the first screw rod 2. Then the second motor 6 is started, and the second motor 6 drives the second screw rod 5 to rotate, driving the moving block 7 to slide longitudinally along the U-shaped slide 4, thereby realizing the positioning of the first hydraulic rod 8 in the axial direction of the second screw rod 5. The first hydraulic rod 8 moves precisely in the plane, which is conducive to completing the grabbing, transfer and placement of the filling bottle 14.

[0028] Preferably, the positioning mechanism includes a block 33 , a fifth hydraulic rod 32 and an arc plate 31 , the block 33 is provided at the telescopic end of the third hydraulic rod 26 , the fifth hydraulic rod 32 is provided on the four sides of the block 33 , and its telescopic end is connected to the arc plate 31 .

[0029] When grabbing the filling bottle 14, the second hydraulic rod 25 is first activated, and its telescopic end is lowered to drive the block 33 from the bottle mouth of the filling bottle 14 to the appropriate position. Then, the four fifth hydraulic rods 32 start working at the same time, extending from the four sides of the block 33, pushing the curved plate 31 to the inner wall of the filling bottle 14, and then the third hydraulic rod 26 is started again, and its telescopic end is shortened to drive the block 33 to rise, and the top surface of the curved plate 31 abuts against the bottom surface of the shoulder of the filling bottle 14, and the filling bottle 14 is grabbed. When the bottle is lifted to a certain height, the four fifth hydraulic rods 32 start working simultaneously, extending from the four sides of the block 33 to push the curved plate 31 toward the inner wall of the filling bottle 14. Since the curved plate 31 matches the surface shape of the filling bottle 14, as the fifth hydraulic rods 32 continue to extend, the curved plate 31 will gradually fit tightly against the filling bottle 14, applying uniform force to the filling bottle 14 from four directions, thereby achieving accurate positioning of the filling bottle 14 and facilitating the smooth entry of the filling bottle 14 into the circular groove.

[0030] Preferably, a countersunk hole 22 is provided at the top of the circular groove, and a sealing gasket 21 is provided in the countersunk hole 22 .

[0031] When the telescopic end of the second hydraulic rod 25 is shortened to drive the filling bottle 14 to rise, the bottle mouth of the filling bottle 14 enters the countersunk hole 22, and the top surface of the bottle mouth abuts against the sealing gasket 21, thereby sealing the filling bottle 14, which is conducive to inflating the filling bottle 14.

[0032] Preferably, the shaping mechanism includes a third hydraulic rod 26, a mold side plate 24, a fourth hydraulic rod 27 and a mold bottom plate 29. The inner wall of the circular groove is relatively provided with a cavity 23 and a slide 28. The slide 28 is located at the bottom of the cavity 23.

The fourth hydraulic rod 27 is relatively provided on the inner wall of the slide 28, and its telescopic end is connected to the mold bottom plate 29. The bottom surface of the mold side plate 24 and the top surface of the mold bottom plate 29 abut each other.

[0033] After the sealing test of the filling bottle 14 is completed, during the sealing test of the filling bottle 14, the value detected by the pressure sensor 30 in the filling bottle 14 remains stable, and it is determined that the leakage test of the filling bottle 14 is qualified and the filling bottle 14 has no penetrating damage; then the third hydraulic rod 26 and the fourth hydraulic rod 27 are started, and the telescopic end of the third hydraulic rod 26 is extended to drive the two mold side plates 24 to fit together, and the telescopic end of the fourth hydraulic rod 27 is extended to drive the two mold bottom plates 29 to fit together, and the space enclosed by the two mold side plates 24 and the two mold bottom plates 29 matches the outer surface of the filling bottle 14, and then the air compressor 1 is started 1. Open the first solenoid valve 9 and the second solenoid valve 19. The air pump 11 passes the pressure pipe 10 and the connecting pipe 18, and the air is filled into the filling bottle 14 from the bottom of the channel 34. As the air continues to enter, the pressure value detected by the pressure sensor 30 continues to increase. When the pressure value reaches the preset value for shaping, the pressure is maintained for a period of time. Due to the restriction of the mold side plate 24 and the mold bottom plate 29, the outer surface of the filling bottle 14 is fitted to the mold side plate 24 and the mold bottom plate 29, smoothing the wrinkles on the outer surface of the filling bottle 14, achieving the purpose of shaping, and preventing the filling bottle 14 with wrinkles from flowing into the next process.

[0034] Preferably, a support plate 15 is further included. The support plate 15 is arranged on the top surface of the first conveyor belt 13, and a plurality of filling bottles 14 are placed in an array on the top surface of the support plate 15.

[0035] The pallet 15 is arranged on the top surface of the first conveyor belt 13. The pallet 15 is in direct contact with the top surface of the first conveyor belt 13. The movement of the first conveyor belt 13 drives the pallet 15 and the filling bottles 14 to move synchronously, which can ensure the stability of the filling bottles 14 during the transmission process, avoid the shaking of the filling bottles 14 caused by the unevenness or vibration of the conveyor belt surface, and is conducive to the completion of the transfer of subsequent batches.

[0036] Preferably, a limiting plate 35 is further included, and the limiting plate 35 is arranged on the top surface of the first conveyor belt 13.

[0037] When the first conveyor belt 13 transports the pallet 15, the side surface of the pallet 15 abuts against the limit plate 35, and the limit plate 35 fixes the lateral position of the filling bottle 14 to ensure that the first conveyor belt 13 transports the pallet 15 to a specific position, avoiding the transfer of the filling bottle 14 being affected by excessive position deviation.

[0038] Preferably, a collecting frame is further included, which is arranged between the frame 1 and the second conveyor belt 17 and has an open top.

[0039] Qualified filled bottles 14 are transferred to the second conveyor belt 17 by the shell 12. The collection frame is used to isolate unqualified products. The collection frame is arranged between the frame 1 and the second conveyor belt 17. It is beneficial to put the filled bottles 14 into the collection frame when they are transferred from the conveyor belt 1 to the second conveyor belt 17, avoiding increasing the moving path of the moving mechanism and ensuring efficient separation.
