[0058] Example 1

[0059] In the automated bottling process of bottled beverages or alcoholic beverages, bottle caps need to be fed into the cap feeding equipment, followed by filling operations and assembly of the bottle caps with the bottle body, thus completing the packaging of bottled beverages or alcoholic beverages.

[0060] In the existing technology, bottle caps are manually fed before entering the cap feeding equipment. Typically, paper boxes containing bottle caps are manually moved and dumped into the receiving device. This feeding method is greatly affected by manual operation, which is not only labor-intensive and inefficient, but also has high labor costs and low automation.

[0061] To solve the above problems, such as Figures 1-4As shown, this embodiment provides a bottle cap feeding device 100, which includes a carrying device 10, a flipping device 20, a receiving device 30, and a conveying device 40. The bottle cap feeding device 100 also includes a frame 60, on which the carrying device 10, flipping device 20, receiving device 30, and conveying device 40 are all mounted. The frame 60 provides stable support for the carrying device 10, flipping device 20, receiving device 30, and conveying device 40. The carrying device 10 carries bottle caps, the flipping device 20 flips the carrying device 10, causing the bottle caps inside to tilt into the receiving device 30, and the conveying device 40 transfers the bottle caps from the receiving device 30 to downstream processing equipment or to a waste bin 45. Through the cooperation of these devices, automated bottle cap feeding is achieved, improving efficiency and automation, reducing labor intensity, and lowering labor costs.

[0062] In addition, the bottle cap feeding equipment 100 adopts a side-flipping feeding method, which saves space and reduces production costs compared to the traditional front-flipping feeding method.

[0063] In existing technologies, paper packaging boxes are used to carry bottle caps. However, using paper packaging boxes involves several steps: removing the stretch film, opening the paper box, untying the straps, taking out the inner packaging bag, emptying the contents into the hopper, and then folding the paper box back together. This process is cumbersome and consumes a large amount of paper. Furthermore, paper packaging boxes are easily damaged and deformed. To address these issues, the carrying device 10 is supported by iron or steel materials, which have high strength, preventing damage to the carrying device 10 during transportation and thus avoiding damage to the bottle caps. Moreover, the carrying device 10 is a cage-like box woven from iron or steel wire, which can be reused multiple times, greatly reducing the use of cardboard boxes, lowering production costs, and promoting low-carbon and environmentally friendly practices.

[0064] Combination Figures 1-4 The structure of the flipping device 20 will be described, such as Figures 1-4 As shown, the flipping device 20 includes a first driving member 21 and a flipping bracket 22. The flipping bracket 22 is disposed at the output end of the first driving member 21, which is mounted on the frame 60. The first driving member 21 drives the flipping bracket 22 to flip, and the flipping bracket 22 supports the carrying device 10. By driving the flipping bracket 22 to flip through the first driving member 21, the carrying device 10 on the flipping bracket 22 is also driven to flip, thereby causing the bottle caps to tilt into the loading device, replacing manual feeding and improving the automation level of the bottle cap loading equipment 100. The first driving member 21 can be any existing speed reducer capable of achieving the above functions.

[0065] Furthermore, such as Figures 1-4As shown, the tilting device 20 also includes a flow guiding mechanism 23, which is positioned above and communicates with the carrying device 10. The flow guiding mechanism 23 is used to guide the bottle caps in the carrying device 10 to the receiving device 30. This facilitates the rapid tilting of the bottle caps in the carrying device 10 into the receiving device 30 without spillage.

[0066] Preferably, such as Figures 1-4 As shown, the bottle cap feeding device 100 also includes a locking device 50, which can abut against the upper surface of the carrier device 10 so that the carrier device 10 abuts against the flipping device 20, thereby preventing the carrier device 10 from falling or shifting during the flipping process.

[0067] Specifically, such as Figures 1-4 As shown, the locking device 50 includes a second frame 51, a rotating rod 52, a connecting piece 53, and a pressure rod 54. The second frame 51 is mounted on the flip bracket 22. The rotating rod 52 is pivotally connected to the second frame 51. The ends of the pressure rod 54 and the rotating rod 52 are respectively fixed to the connecting piece 53. When the rotating rod 52 rotates, the rotating rod 52 drives the pressure rod 54 through the connecting piece 53 to switch between the locked position abutting against the bearing device 10 and the unlocked position away from the bearing device 10. In use, rotate the connecting piece 53 at one end of the rotating rod 52 clockwise, which in turn drives the pressure rod 54 to move downward. When the pressure rod 54 is at the bottom, it abuts against the upper surface of the bearing device 10 to lock the bearing device 10. At this time, the connecting piece 53 is threadedly connected to the second frame 51 with bolts to improve the stability of the pressure rod 54 locking the bearing device 10. After the bottle caps in the bearing device 10 are filled, rotate the connecting piece 53 counterclockwise, which in turn drives the pressure rod 54 to move upward so that the pressure rod 54 moves away from the bearing device 10, thereby unlocking the bearing device 10.

[0068] Furthermore, such as Figures 1-4 As shown, the locking device 50 also includes a leak-proof pressure plate 55 and a connector 56. The leak-proof pressure plate 55 is positioned above the support device 10 and is rotatably connected to the flipping bracket 22. The connector 56 is fixed to the leak-proof pressure plate 55 and is sleeved on the pressure rod 54. When the pressure rod 54 abuts against the support device 10, the leak-proof pressure plate 55 is in contact with the upper side of the support device 10. As the pressure rod 54 moves up and down, the connector 56 moves up and down with the pressure rod 54. Since the connector 56 is sleeved on the pressure rod 54, it can slide along the extension direction of the pressure rod 54. When the pressure rod 54 moves downward, the connector 56 drives the leak-proof pressure plate 55 to move downward. At this time, the leak-proof pressure plate 55 is in contact with the upper side of the support device 10, preventing the bottle cap from falling off through the gap during the flipping process of the support device 10.

[0069] Furthermore, such as Figures 1-4As shown, the locking device 50 also includes a third driving member 57, which is mounted on the flipping device 20. A rotating member is rotatably connected to the output end of the third driving member 57, and the rotating member is fixed to the rotating rod 52, thereby causing the third driving member 57 to drive the rotating rod 52 to rotate. The third driving member 57 can be a linear cylinder. In other embodiments, the third driving member 57 can also be a rotary cylinder or a rotary motor, with the output end of the rotary cylinder or rotary motor fixed to the rotating rod 52, thereby driving the rotating rod 52 to rotate, which in turn causes the rotating rod 52 to sequentially move the connecting piece 53 and the pressure rod 54. This achieves automatic locking or unlocking of the pressure rod 54 on the carrying device 10, further improving the automation level of the bottle cap feeding equipment 100.

[0070] Combination Figures 1-4 The structure of the material receiving device 30 will be described, such as... Figures 1-4 As shown, the receiving device 30 includes a storage bin 31 and a cover plate 32. The storage bin 31 has an open end, and the cover plate 32 is disposed at the open end of the storage bin 31 to seal the open end of the storage bin 31. When bottle caps need to be filled, the cover plate 32 is opened; after the bottle cap filling is completed, the cover plate 32 is placed on the storage bin 31 to prevent dust and debris from contaminating the bottle caps inside the storage bin 31.

[0071] Furthermore, Figures 1-4 As shown, the receiving device 30 also includes a second driving member 33, which is installed at both ends of the storage bin 31 along its length. A cover plate 32 is disposed at the output end of the second driving member 33. The side of the cover plate 32 away from the flipping mechanism is used for rotational connection of the storage bin 31. The second driving member 33 can drive the cover plate 32 to open or close the storage bin 31, realizing the automatic opening or closing of the cover plate 32, further improving the automation level of the bottle cap feeding device 100.

[0072] Furthermore, the receiving device 30 also includes an upper detection mechanism and a lower detection mechanism, both of which are photoelectric sensors. The upper detection mechanism is located at the lower part of the side of the storage hopper 31 and is used to detect whether the bottle caps in the storage hopper 31 are full. The lower detection mechanism is located at the lower part of the side of the storage hopper 31 and is used to detect whether the bottle caps in the storage hopper 31 are short of material. Specifically, the bottle cap feeding device 100 also includes a control component and a detection element. The detection element is located on the flipping bracket 22 and is a photoelectric sensor, used to detect whether the flipping bracket 22 is carrying the carrying device 10. The detection component, the upper detection mechanism, and the lower detection mechanism are electrically connected to the control component. When the lower detection mechanism detects a material shortage and the detection component detects that the carrying device 10 is on the flipping bracket 22, it transmits a material shortage signal to the control component. The control component controls the flipping device 20 to flip the carrying device 10 and deliver bottle caps into the storage bin 31. When the upper detection mechanism detects a full material, it transmits a material shortage signal to the control component, and the control component controls the flipping device 20 to stop working.

[0073] It should be noted that the control component is existing technology, and any control component capable of achieving the above functions can be used in this embodiment.

[0074] Combination Figures 1-4 The structure of the material conveying device 40 will be described, such as... Figures 1-4 As shown, the feeding device 40 includes a first frame 41, two conveyor wheels 42, a drive motor 43, and an annular conveyor belt 44. The first frame 41 is mounted on the frame 60. The two conveyor wheels 42 are pivotally connected to the first frame 41. The drive motor 43 is connected to at least one conveyor wheel 42. The annular conveyor belt 44 surrounds the two conveyor wheels 42 and is tensioned by both conveyor wheels 42. Bottle caps are placed on the outer surface of the annular conveyor belt 44. A discharge port is provided below the storage bin 31, and the annular conveyor belt 44 is located below the discharge port. During operation, the drive motor 43 drives the annular conveyor belt 44 to rotate and move, thereby automatically conveying the bottle caps to the downstream processing equipment and further improving the automation level of the bottle cap feeding device 100.

[0075] Furthermore, such as Figures 1-4 As shown, a surplus material bin 45 is provided at one end of the circular conveyor belt 44. When there are excess bottle caps in the storage bin 31, the drive motor 43 flips and transports the excess bottle caps into the surplus material bin 45 for storage.

[0076] Furthermore, such as Figures 1-4As shown, a safety switch 71 is installed on the frame 60. The safety switch 71 can be any existing proximity switch, and it is electrically connected to the control component. When the bottle cap feeding equipment 100 needs maintenance, the tilting device 20 moves to its highest position, the safety switch 71 detects the tilting device 20, and the operator manually presses the safety switch 71. The control component then stops the bottle cap feeding equipment 100 to ensure the safety of the maintenance personnel.

[0077] Furthermore, the bottle cap feeding device 100 is also equipped with a safety light curtain, which is mounted on the flipping bracket 22. Specifically, the safety light curtain is an infrared sensor, which is electrically connected to the control component. When the device is in operation, if the safety light curtain detects someone entering the device, it transmits a signal to the control component, which then stops the device, ensuring the safety of the bottle cap feeding device 100.

[0078] For ease of understanding, combined with Figures 1-4 The working process of the bottle cap feeding equipment 100 is described below:

[0079] 1) The load-bearing device 10 is fed onto the tilting bracket 22 by a forklift or hydraulic trailer;

[0080] 2) The third driving member 57 drives the rotating rod 52 to rotate, thereby causing the pressure rod 54 to press against the upper surface of the bearing device 10, and the anti-leakage pressure plate 55 to connect with the side of the bearing device 10.

[0081] 3) The second driving component 33 drives the cover plate 32 to open;

[0082] 4) The first driving component 21 drives the flipping bracket 22 to flip, thereby causing the bottle cap in the carrying device 10 to tilt into the storage bin 31 under the action of the flow guiding mechanism 23.

[0083] 5) The second driving component 33 drives the cover plate 32 to close;

[0084] 6) Drive motor 43 drives the circular conveyor belt 44 to move, open the discharge port of storage bin 31, and transport the bottle caps in storage bin 31 to downstream processing equipment;

[0085] 7) When there is unused material in the storage bin 31, the drive motor 43 flips and transports the bottle caps to the surplus material bin 45 for storage.

[0089] The locking device 50 presses the carrying device 10 against the flipping device 20;

[0090] The flipping device 20 flips the carrying device 10, tilting the bottle caps inside the carrying device 10 into the receiving device 30;

[0091] The conveying device 40 transports the bottle caps in the receiving device 30 to the downstream processing equipment or the waste bin 45.

[0092] By coordinating various devices, the bottle cap feeding process is automated, improving efficiency and achieving a high degree of automation, thus reducing labor intensity and labor costs.

[0093] The above-mentioned bottle cap feeding equipment also includes the following steps:

[0095] The control component controls the opening or closing of the flipping device 20 based on the signals fed back by the upper and lower detection mechanisms.

[0096] The material level in the receiving device 30 is monitored in real time by the upper and lower detection mechanisms, and the flipping and feeding action of the flipping device 20 is controlled in an adaptive manner to avoid too many or too few bottle caps in the receiving device 30, which would affect the production process.
