Description

Technical Field

[0001] The invention relates to an empty bottle flexible conveying device and a filling production line, belonging to the technical field of food machinery and equipment. Background Art

[0002] With the rapid development of the global food industry, market demand for various types of food machinery and equipment has shown a significant growth trend, especially for food packaging machinery and equipment. In recent years, with consumers' growing health awareness and improved quality of life, the market demand for beverages, as convenient and popular drinks, has continued to rise, greatly driving the prosperity and development of the beverage market. This trend has directly prompted beverage manufacturers to continuously expand their production scale, and the demand for efficient and reliable machinery and equipment has become increasingly urgent.

[0003] Filling is a crucial step in the beverage production process, directly impacting not only the product's hygienic quality and safety standards but also filling accuracy and production efficiency. Consequently, beverage manufacturers are placing increasingly high demands on filling equipment, expecting it to be highly automated and intelligent to ensure stable and efficient production processes. Against this backdrop, flexible conveying mechanisms, capable of adapting to the transport needs of products of varying specifications and improving the flexibility and adaptability of production lines, have become essential components in filling equipment.

[0004] However, traditional filling and conveying mechanisms often have design limitations, such as a lack of adaptability to empty bottles of varying sizes, easy wear and tear due to friction during conveyance, and a lack of empty bottle rejection mechanisms. These issues not only impact production line efficiency and product quality, but can also lead to equipment failure and resource waste. Specifically, when empty bottles are incorrectly sized, traditional equipment often fails to effectively handle them, resulting in turntable failures and empty bottle accumulation. Defective empty bottles that appear during the filling process can lead to inconsistent filling times, impacting overall production schedules and product quality. Summary of the Invention

[0032] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The present invention provides a flexible empty bottle conveying device. In some embodiments, the device includes a mounting mechanism 100, a conveyor belt transmission mechanism 200, and a star-shaped turntable transmission mechanism 300.

[0033] In some embodiments, the mounting mechanism 100 includes a frame 1, the frame 1 is provided with a display screen 2 and a glass door 5, the glass door 5 is connected to the frame 1 through a door bolt 4, the glass door 5 is provided with a door handle 6, a table 3 is fixedly connected to the bottom of the frame 1, a plurality of frame pillars 7 are fixedly connected to the bottom of the plurality of frame pillars 7, and a base plate 8 is fixedly connected to the bottom of the plurality of frame pillars 7.

[0034] In some embodiments, the conveyor belt transmission mechanism 200 is installed in the frame 1; the conveyor belt transmission mechanism 200 includes a rotatable first conveyor belt 23 and a rotatable second conveyor belt 24, and the left and right sides of the first conveyor belt 23 and the second conveyor belt 24 are both provided with first side panels 9, and the front and rear sides of the first conveyor belt 23 and the second conveyor belt 24 are both provided with second side panels 10, and the bottoms of the first conveyor belt 23 and the second conveyor belt 24 are both provided with conveyor belt bottom plates 13, and the first side plate 9 and the conveyor belt bottom plate 13 are fixedly connected to the second side plate 10, one end of the first conveyor belt 23 passes through one side of the frame 1, and one end of the second conveyor belt 24 passes through the other side of the frame 1.

[0035] Furthermore, the second side plate 10 on one side of the first conveyor belt 23 is fixedly connected to a motor fixing seat 15, and the motor fixing seat 15 is installed with a first motor 16. The first motor 16 is driven and connected to a first driving shaft 17. The first driving shaft 17 is installed on one side of the second side plate 10 of the first conveyor belt 23, and a first driven shaft 18 is installed on the other side of the second side plate 10 of the first conveyor belt 23. The first driving shaft 17 and the first driven shaft 18 are connected through the first conveyor belt 23.

[0036] Furthermore, the first conveyor belt 23 and the second conveyor belt 24 are arranged horizontally, and the second conveyor belt 24 is located on one side of the first conveyor belt 23; a second driving shaft 19 is installed on one side of the second side plate 10 of the second conveyor belt 24, and a second driven shaft 20 is installed on the other side of the second side plate 10 of the second conveyor belt 24, and the second driving shaft 19 and the second driven shaft 20 are connected through the second conveyor belt 24; the first driven shaft 18 and the second driving shaft 19 are coaxial, and the first driven shaft 18 and the second driving shaft 19 are connected through a coupling 22.

[0037] In this embodiment, the first motor 16 of the conveyor belt transmission mechanism 200 drives the first driving shaft 17 to rotate. The first driving shaft 17 drives the first driven shaft 18 to rotate via the first conveyor belt 23, thereby achieving horizontal conveyance of empty bottles on the first conveyor belt 23. Because the first driven shaft 18 is connected to the second driving shaft 19 via a coupling 22, the rotation of the first driven shaft 18 drives the second driving shaft 19 to rotate synchronously via the coupling 22. The second driving shaft 19 drives the second driven shaft 20 to rotate via the second conveyor belt 24, thereby achieving horizontal conveyance of empty bottles on the second conveyor belt 24. Thus, the conveyor belt transmission mechanism 200 uses a single first motor 16 to drive the first and second conveyor belts 23, 24 to rotate synchronously to transport empty bottles. This ensures that the conveying rhythm of the first and second conveyor belts 23, 24 is consistent, resulting in a clear process rhythm for the entire flexible empty bottle conveying device and facilitating more efficient empty bottle conveying operations. The first motor 16 can be a three-phase asynchronous motor.

[0038] Furthermore, the two second side plates 10 of the first conveyor belt 23 are fixedly connected to the side fenders 12 above through a plurality of fixed plates 11, and the two side fenders 12 of the first conveyor belt 23 are respectively located on both sides above the first conveyor belt 23; the two second side plates 10 of the second conveyor belt 24 are fixedly connected to the side fenders 12 above through a plurality of fixed plates 11, and the two side fenders 12 of the second conveyor belt 24 are respectively located on both sides above the second conveyor belt 24.

[0039] In this embodiment, the conveyor belt transmission mechanism 200 is provided with two side baffles 12 on both sides above the conveyor belt, and the two side baffles 12 are used to shield the empty bottles transported on the conveyor belt to prevent the empty bottles from falling from the conveyor belt during transportation.

[0040] Furthermore, pillars 14 are fixed below the conveyor belt bottom plate 13 , and a plurality of the pillars 14 are fixedly connected to the platform 3 .

[0041] In this embodiment, the conveyor belt transmission mechanism 200 is fixedly connected to the platform 3 of the installation mechanism 100 through a plurality of pillars 14 at the bottom thereof.

[0042] In some embodiments, the star-shaped turntable transmission mechanism 300 is installed in the frame 1; the star-shaped turntable transmission mechanism 300 includes a first star-shaped turntable 25, the lower portion of the first star-shaped turntable 25 is connected to a second star-shaped turntable 26 via a plurality of turntable pads 27, a turntable shaft 28 is connected between the first star-shaped turntable 25 and the second star-shaped turntable 26, the lower portion of the turntable shaft 28 passes through the table 3 and is connected to a bevel gear 30, a motor pad 37 is installed above the bottom plate 8, A second motor 36 is fixedly mounted on the motor pad 37, and the second motor 36 is driven and connected to a driving pulley 33, and the driving pulley 33 is connected to a driven pulley 34 through a transmission belt 35, and the driven pulley 34 is connected to a reducer 31, and the output end of the reducer 31 is connected to a bevel gear 30; a turntable support 32 is sleeved on the outer side of the turntable shaft 28, and the turntable support 32 is fixedly connected to the table 3, and the turntable support 32 is connected to the turntable shaft 28 through a bearing.

[0043] In this embodiment, the star-shaped turntable transmission mechanism 300 drives the driving pulley 33 to rotate via a second motor 36. The driving pulley 33 drives the driven pulley 34 to rotate via a transmission belt 35. The driven pulley 34 is connected to the input end of the reducer 31. The driven pulley 34 drives the bevel gear 30 to rotate via the reducer 31. The bevel gear 30 drives the turntable shaft 28 to rotate. The turntable shaft 28 drives the first star-shaped turntable 25 and the second star-shaped turntable 26 to rotate. In addition, the turntable support 32 is connected to the turntable shaft 28 via a bearing, allowing the turntable shaft 28 to rotate within the turntable support 32. The turntable support 32 is fixedly connected to the table 3. The support provided by the turntable support 32 prevents the turntable shaft 28 from deviating during rotation, thereby ensuring the stability and accuracy of the rotation of the turntable shaft 28 and the first star-shaped turntable 25 and the second star-shaped turntable 26.

[0044] Furthermore, the feed port of the first conveyor belt 23 is located on one side of the first star-shaped turntable 25 and the second star-shaped turntable 26, and the discharge port of the second conveyor belt 24 is located on one side of the first star-shaped turntable 25 and the second star-shaped turntable 26. The first star-shaped turntable 25 and the second star-shaped turntable 26 are configured to transport the empty bottles on the second conveyor belt 24 to the first conveyor belt 23 by rotation.

[0045] In this embodiment, empty bottles enter the second conveyor belt 24 from the feed port of the second conveyor belt 24 for transportation. The empty bottles transported on the second conveyor belt 24 enter the first star-shaped turntable 25 and the second star-shaped turntable 26 from the discharge port of the second conveyor belt 24. The first star-shaped turntable 25 and the second star-shaped turntable 26 rotate to transport the empty bottles to the feed port of the first conveyor belt 23. The first conveyor belt 23 transports the empty bottles, and finally the empty bottles are transported out from the discharge port of the first conveyor belt 23. Thus, by rotating the first and second star-shaped turntables 25 and 26, and by the arrangement of the first and second star-shaped turntables 25 and 26 with the first and second conveyor belts 23 and 24, empty bottles can be transported from the second conveyor belt 24 to the first conveyor belt 23.

[0046] Furthermore, a number of evenly distributed card slots are provided on the periphery of the first star-shaped turntable 25 and the second star-shaped turntable 26, and the card slots are used to clamp empty bottles. A bottle pulling plate 29 is connected above the first star-shaped turntable 25, and the bottle pulling plate 29 is an L-shaped structure. The bottle pulling plate 29 is configured to rotate with the first star-shaped turntable 25 to transfer the empty bottles in the card slots of the first star-shaped turntable 25 and the second star turntable 26 to the first conveyor belt 23.

[0047] Furthermore, a bottle-blocking ring 38 is provided around the first star-shaped turntable 25. The bottle-blocking ring 38 is an annular opening structure. The bottle-blocking ring 38 with an annular opening structure extends clockwise from one end of the discharge port of the second conveyor belt 24 to one end of the feed port of the first conveyor belt 23; the discharge port of the second conveyor belt 24 and the feed port of the first conveyor belt 23 are both located in the opening of the bottle-blocking ring 38, and the bottle-blocking ring 38 is staggered with the bottle-pulling plate 29.

[0048] In this embodiment, the bottle stop ring 38 has two functions: changing the movement direction of the empty bottle and fixing the movement of the empty bottle. The size of the inner ring of the bottle stop ring 38 matches the slot of the star-shaped turntable, which not only ensures that the empty bottles will not fall during transportation, but also ensures that the production line can transport empty bottles of different sizes, reflecting the flexible design of the filling production line.

[0049] Specifically, the second conveyor belt 24 transports empty bottles one by one to the slots on the outer periphery of the first and second star-shaped turntables 25 and 26. The first and second star-shaped turntables 25 and 26 rotate to hold the empty bottles in the slots one by one. When the first star-shaped turntable 25 drives the empty bottles to rotate to the bottle retaining ring 38 near the feed port of the first conveyor belt 23, the bottle retaining ring 38 blocks the empty bottles stuck in the slots on the outer periphery of the first star-shaped turntable 25. Simultaneously, the rotation of the first star-shaped turntable 25 drives the L-shaped bottle pull plate 29 to rotate as well, transferring the empty bottles blocked by the bottle retaining ring 38 to the first conveyor belt 23. Because the bottle retaining ring 38 and the bottle pull plate 29 are staggered, the bottle pull plate 29 does not contact the bottle retaining ring 38 during rotation, preventing interference between the bottle retaining ring 38 and the bottle pull plate 29. Therefore, the star-shaped turntable transmission mechanism 300 can smoothly transport the empty bottles clamped in the outer peripheral grooves of the first star-shaped turntable 25 and the second star-shaped turntable 26 to the first conveyor belt 23 through the cooperation between the bottle pulling plate 29 and the bottle blocking ring 38, thereby realizing smooth transfer of the empty bottles.

[0050] Furthermore, a bottle pad plate 40 is connected to the bottom of the bottle blocking ring 38 through several bottle blocking ring pads 39. The bottle pad plate 40 is located below several card slots on the outer periphery of the first star-shaped turntable 25 and the second star-shaped turntable 26. The bottle pad plate 40 is used to receive empty bottles in the card slots. The bottom of the bottle pad plate 40 is fixedly connected to the bottle blocking ring pillar 41, and the bottle blocking ring pillar 41 is fixedly mounted on the table 3.

[0051] In this embodiment, a bottle support plate 40 receives empty bottles in the outer peripheral slots of the first and second star-shaped turntables 25 and 26 to prevent them from falling. A bottle retaining ring 38 is fixed to the bottle support plate 40, and the turntable shaft 28 passes through a hole defined in the center of the bottle support plate 40 and is fixedly connected to the first and second star-shaped turntables 25 and 26.

[0052] Furthermore, the inner circumference of the bottle retaining ring 38 is wrapped with a protective pad, and the height of the bottle retaining ring support 41 is adjustable.

[0053] The flexible empty bottle conveying device provided in this embodiment of the present application can adapt to empty bottles of different sizes by wrapping a protective pad on the inner periphery of the bottle stop ring 38, that is, the contact point between the bottle stop ring 38 and the empty bottle, and adjusting the height of the bottle stop ring support 41, thereby effectively solving the problems that may be encountered by traditional filling and conveying mechanisms when conveying empty bottles of different specifications, and improving the stability and production efficiency of the production line.

[0054] In some embodiments, a rejection device 42 is fixedly installed above the bottle blocking ring 38, and the rejection device 42 includes a hydraulic cylinder 421, a hydraulic rod 422 driven by the hydraulic cylinder 421, a slider 423 rotatably connected to the hydraulic rod 422, a first clamp hand 424, and a second clamp hand 425. The first clamp hand 424 and the second clamp hand 425 are arranged opposite to each other, and a slide groove 429 is provided on the side of the first clamp hand 42 away from the second clamp hand 425, and the slider 423 is slidably connected in the slide groove 429; the upper end of the first clamp hand 424 facing the second clamp hand 425 is fixedly connected to the first oblique rod 4241, and the upper end of the second clamp hand 425 facing the first clamp hand 424 is fixedly connected to the second oblique rod 425 1. The first oblique rod 4241 and the second oblique rod 4251 are rotatably connected via a first connecting rod 426; the first oblique rod 4241 is rotatably connected to a first limiting rod 4242, the second oblique rod 4251 is rotatably connected to a second limiting rod 4252, and the first limiting rod 4242 and the second limiting rod 4252 are rotatably connected via a second connecting rod 427; the first clamping hand 42 and the second clamping hand 425 are both provided with a concave surface 428 adapted to the empty bottle on the opposite side, and the concave surface 428 is used to clamp the empty bottle; the rejection device 42 is also equipped with an infrared detector (not shown in the figure) for identifying unqualified empty bottles (defective products), and the second clamping hand 425 is installed on the bottle blocking ring 38 through a moving mechanism (not shown in the figure).

[0055] In this embodiment, when an empty bottle passes through the first star-shaped turntable 25, the infrared detector installed in the rejection device 42 uses infrared thermal imaging nondestructive testing technology. This technology, based on the basic principles of infrared radiation, measures the energy flow within an object through infrared radiation analysis methods. The detection results are displayed using an infrared thermal imager, allowing for intuitive identification of defects. When an object has a defect, a temperature difference forms between the defective and non-defective areas of the object, resulting in a difference in infrared radiation intensity. The infrared thermal imager can detect this temperature change, thereby determining the defect and identifying whether the empty bottle is defective. If the empty bottle is identified as defective, the hydraulic cylinder 421 of the rejection device 42 drives the hydraulic rod 422 to move, which in turn drives the slide 423 to slide within the slide groove 429 of the first gripper hand 424. Since the first oblique rod 4241 of the first clamping hand 424 and the second oblique rod 4251 of the second clamping hand 425 are rotatably connected by the first connecting rod 426, the hydraulic cylinder 421 drives the first clamping hand 424 to move toward the second clamping hand 425, so that the concave surface 428 of the first clamping hand 424 and the concave surface 428 of the second clamping hand 425 jointly clamp the defective empty bottle, and then the moving mechanism (not shown in the figure) between the second clamping hand 425 and the bottle blocking ring 38 drives the rejection device 42 and the unqualified empty bottle clamped by it to move, thereby realizing the removal of the unqualified empty bottle from the star-shaped turntable.

[0056] The first limiting rod 4242 and the second limiting rod 4252 are rotatably connected via a second connecting rod 427, limiting the opening and closing angle between the first and second gripping arms 424, 425, preventing excessive opening and closing angles from affecting the normal operation of the device. Furthermore, the ends of the hydraulic cylinder 421 are fixed (not shown in the figure), and the movement of the hydraulic cylinder 421 enables the rejection device 42 to tighten or loosen the empty bottle.

[0057] In addition, the present invention also provides a filling production line, including the above-mentioned flexible empty bottle conveying device.

[0058] The workflow of the present invention is:

[0059] Empty bottles are transported from the upstream of the production line onto the second conveyor belt 24. The first motor 16 is activated, driving the first and second conveyor belts 23 and 24 to rotate synchronously. The second conveyor belt 24 transports the empty bottles one by one to the peripheral slots of the first and second star-shaped turntables 25 and 26. The first and second star-shaped turntables 25 and 26 rotate, clamping the empty bottles one by one in the peripheral slots. The first star-shaped turntable 25 rotates the empty bottles. When the empty bottles pass through the rejection device 42, the rejection device 42 automatically detects and identifies the quality of the empty bottles. If any unqualified (defective) empty bottles are found, the rejection device 42 automatically removes them from the star-shaped turntables. When the empty bottles detected by the rejection device 42 rotate to the bottle blocking ring 38 close to the feed port of the first conveyor belt 23 under the drive of the star-shaped turntable, the bottle blocking ring 38 blocks the empty bottles stuck in the outer peripheral groove of the first star-shaped turntable 25. At the same time, the L-shaped bottle pulling plate 29 is driven to rotate during the rotation of the first star-shaped turntable 25. The empty bottles blocked at the bottle blocking ring 38 are transferred to the first conveyor belt 23 by the L-shaped bottle pulling plate 29. The first conveyor belt 23 transports the empty bottles to the downstream end of the production line for filling process, thereby completing the empty bottle conveying operation.

[0060] In summary, the present invention provides a flexible conveying device and filling production line for empty bottles. A protective pad is provided at the contact point between the bottle retaining ring and the empty bottles to prevent wear of the empty bottles due to friction during transportation. The height of the entire bottle retaining ring can be changed by changing the height of the bottle retaining ring support, thereby accommodating the transportation of empty bottles of different sizes. The bottle retaining ring is designed with an annular opening structure, and can be smoothly transferred to the conveyor belt in conjunction with the bottle pull plate. The size of the inner ring of the bottle retaining ring matches the slot of the star-shaped turntable, which not only ensures that the empty bottles will not fall during transportation, but also ensures that the production line can transport empty bottles of different sizes, reflecting the flexible design of the filling production line. In addition, the present invention adds an empty bottle rejection device, while traditional filling and conveying mechanisms do not have an empty bottle rejection device, which may lead to two undesirable operating conditions: one is that when the empty bottle size is incorrect, the turntable will malfunction, and empty bottles will accumulate on the empty bottle conveyor line, causing a burden on the production line; the other is that when the empty bottle is filled, the defective empty bottle will cause the expected filling time to be inconsistent, thereby affecting product quality and production time, resulting in waste of resources. The rejection device provided by the present invention can effectively reject unqualified empty bottles, effectively solving the problems that traditional filling and conveying mechanisms may encounter when conveying empty bottles of different specifications, improving the stability and production efficiency of the production line, reducing equipment failure rate and resource waste, and providing strong support for the sustainable development of beverage production enterprises.
