Description

Technical Field

[0001] This invention relates to the field of bottle cap manufacturing technology, and more specifically to a bottle cap production chain. Background Technology

[0002] Bottle caps are a crucial component of food and beverage packaging and the first point of contact consumers have with the product. They maintain the airtightness of the contents, provide tamper-evident protection, and ensure safety. Therefore, they are widely used in bottled products, making bottle caps a key product in bottled packaging and an upstream industry for the food, beverage, wine, chemical, and pharmaceutical industries. Early bottle cap development utilized cork, tin crown caps, and screw caps. Today, the industry has expanded to include aluminum long-neck caps, aluminum caps for carbonated beverages, hot-fill aluminum caps, aluminum caps for injection solutions, pharmaceutical caps, flip-top ring caps, safety claw caps, and plastic bottle caps, among others.

[0003] After production, plastic bottle caps need to be packed for easy transportation. Inside the box, all bottle caps face the same direction, either right-side up or left-side down. Because the front or back of the bottle cap has grooves, and the diameter of the front of the bottle cap is different from that of the back, when the front of the bottle cap is pressed against the back of the bottle cap in the adjacent layer, it is easy for it to enter the grooves, causing the bottle cap to flip or shift. This results in the bottle caps being misaligned and disordered inside the box, making them prone to scratching and bumping each other. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a bottle cap production chain.

[0005] One embodiment of the present invention provides a bottle cap production chain, comprising: a bottle cap injection molding device, a first conveying mechanism, a second conveying mechanism, and a case packer connected in sequence;

[0006] The bottle cap injection molding device is used to produce bottle caps facing the correct direction.

[0007] A purging mechanism is provided between the first conveying mechanism and the second conveying mechanism;

[0008] The second conveying mechanism is provided with a conveying channel, a first diversion channel, a second diversion channel, a guide component, and a flipping mechanism. The first conveying mechanism is connected to the conveying channel. The conveying channel is connected to the first diversion channel or the second diversion channel through the guide component. The flipping mechanism is used to flip the bottle cap from the front-facing position to the back-facing position. The flipping mechanism is provided with an upper channel, a flipping channel, and a lower channel connected in sequence. The upper channel and the lower channel are both connected to the second diversion channel.

[0009] The case packer is connected to the first diversion channel and the second diversion channel respectively, and is used to put the positive-facing bottle cap and the negative-facing bottle cap into the case in sequence, so that the positive-facing bottle cap and the negative-facing bottle cap in the case are arranged at intervals from top to bottom.

[0010] In some optional embodiments, the guiding assembly includes a support beam, a first telescopic assembly, a first connecting rod, two second connecting rods, and two guide rods. The support beam is mounted on the second conveying mechanism. The two second connecting rods are rotatably connected to the support beam. The first connecting rod is rotatably connected to each of the two second connecting rods, so that the support beam, the first connecting rod, and the two second connecting rods together form a parallelogram structure. The first telescopic assembly is mounted on the support beam, and its telescopic end is rotatably connected to one of the second connecting rods. The guide rods are correspondingly connected to the second connecting rods. A guiding channel communicating with the conveying channel is formed between the two guide rods. The first telescopic assembly drives the second connecting rods to rotate, thereby causing the guide rods to rotate, so that the guiding channel communicates with one of the diversion channels.

[0011] In some alternative embodiments, a universal joint bearing is provided on one of the second connecting rods, and the output end of the first telescopic assembly is rotatably connected to the second connecting rod through the universal joint bearing.

[0012] In some alternative implementations, a counter is provided on one side of the conveying channel, and the counter is signal-connected to the first telescopic component.

[0013] In some alternative embodiments, the blowing mechanism includes a deceleration mechanism and a blower. The deceleration mechanism includes a plurality of deceleration rollers disposed between the first conveying mechanism and the second conveying mechanism. The plurality of deceleration rollers are arranged sequentially from the first conveying mechanism to the second conveying mechanism and are rotatably connected to the first conveying mechanism. The blower is disposed on one side of the plurality of deceleration rollers for blowing air onto the bottle caps on the first conveying mechanism and the plurality of deceleration rollers.

[0014] In some alternative implementations, the distance between the reduction roller closest to the first conveying mechanism and the reduction roller closest to the second conveying mechanism is no greater than 3 / 5 and no less than 1 / 3 of the diameter of the bottle cap.

[0015] In some alternative implementations, the top of the reduction roller is higher than the height of the conveying surface of the first conveying mechanism.

[0016] In some alternative embodiments, a support beam is provided above the first conveying mechanism, and a pressure rod is provided on the support beam. The pressure rod is rotatably connected to the support beam and can be flipped up and down relative to the support beam.

[0017] In some alternative implementations, the bottle cap production chain also includes: a visual inspection mechanism, a rejection mechanism, and a waste bin;

[0018] The visual inspection includes a movable support frame, a CCD industrial camera, a ring light source, and an image processing module. The movable support frame is disposed on one side of the first conveying mechanism. The CCD industrial camera and the ring light source are disposed on the movable support frame and located above the first conveying mechanism. The CCD industrial camera and the ring light source are arranged sequentially from top to bottom. The image processing module is signal-connected to the CCD industrial camera.

[0019] The rejection mechanism includes a second telescopic component and a push plate. The second telescopic component is disposed on one side of the first conveying mechanism. The second telescopic component is also signal-connected to the image processing module. The push plate is connected to the output end of the second telescopic component.

[0020] The waste box is located on the side of the first conveying mechanism away from the second telescopic component, and the pusher plate pushes the bottle cap on the first conveying mechanism into the waste box under the drive of the second telescopic component.

[0021] In some optional embodiments, the case packer includes two cap arrangement mechanisms and a clamping mechanism. The two cap arrangement mechanisms are respectively connected to the first diversion channel and the second diversion channel. One cap arrangement mechanism is used to arrange the positively oriented bottle caps into the positively oriented bottle cap array, and the other cap arrangement mechanism is used to arrange the negatively oriented bottle caps into the negatively oriented bottle cap array. The clamping mechanism is used to clamp the positively oriented bottle cap array and the negatively oriented bottle cap array into the case in sequence, so that the positively oriented bottle cap array and the negatively oriented bottle cap array in the case are arranged alternately from top to bottom.

[0022] Compared to existing technologies, the bottle cap production chain of this invention can separate the bottle caps produced by the bottle cap injection molding device into two batches. Then, the bottle caps in one batch are flipped from the front to the back. The front and back bottle caps are then sequentially packed into a box by a packing machine, so that the front of the bottle cap abuts against the front of the bottle cap in the adjacent layer, and the back of the bottle cap abuts against the back of the bottle cap in the adjacent layer. This ensures that the bottle caps are stably abutted against each other and are not easy to slide against each other, improving the stability of the bottle caps placed in the box and thus avoiding the bottle caps shifting, sliding, or flipping during transportation.

[0023] To provide a clearer understanding of the present invention, the specific embodiments of the present invention will be described below in conjunction with the accompanying drawings. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of the present invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified, and "several" means one or more.

[0035] Please see Figure 1 This is a schematic diagram of the top structure of a bottle cap production chain according to an embodiment of the present invention. The bottle cap production chain includes: a bottle cap injection molding device 10, a first conveying mechanism 20, a second conveying mechanism 30, and a case packer 40 connected in sequence.

[0036] Please see Figure 2 This is a schematic diagram of the structure of a bottle cap after it has been loaded into a case by a case packer, according to an embodiment of the present invention. The bottle cap injection molding device 10 is used to produce the positively oriented bottle cap 11. It should be noted that "the bottle cap injection molding device 10 is used to produce the positively oriented bottle cap 11" means that the bottle cap produced by the bottle cap injection molding device 10 is in the positively oriented position when it falls into the first conveying mechanism 20. The positively oriented bottle cap 11 can be in a position where the groove for cooperating with the bottle body faces upward or downward. The positively oriented bottle cap 11 and the negatively oriented bottle cap 12 are only different in their orientation relative to the horizontal plane; their structures are the same. In this embodiment, the positively oriented bottle cap 11 is in a position where the groove for cooperating with the bottle body faces downward.

[0037] Please see Figure 3 and Figure 4 , Figure 3 This is a cross-sectional view of a flip-top mechanism according to an embodiment of the present invention. Figure 4This is a partial structural diagram of the top of the first conveying mechanism according to an embodiment of the present invention. A purging mechanism 50 is provided between the first conveying mechanism 20 and the second conveying mechanism 30. The second conveying mechanism 30 is provided with a conveying channel 31, a first diversion channel 32, a second diversion channel 33, a guide component 34, and a flipping mechanism 35. The first conveying mechanism 20 is connected to the conveying channel 31. The conveying channel 31 is connected to the first diversion channel 32 or the second diversion channel 33 through the guide component 34. The flipping mechanism 35 is used to flip the bottle cap 11 facing the right to the bottle cap 12 facing the wrong. The flipping mechanism 35 is provided with an upper channel 351, a flipping channel 352, and a lower channel 353 connected in sequence. Both the upper channel 351 and the lower channel 353 are connected to the second diversion channel 33. The case packer 40 is connected to the first diversion channel 32 and the second diversion channel 33 respectively.

[0038] Bottle caps 11 produced by the bottle cap injection molding device 10, facing forward, pass through the first conveying mechanism 20 and the blowing mechanism 50 to reach the conveying channel 31. The guide component 34 flows through the first diversion channel 32. When N facing bottle caps 11 enter the first diversion channel 32 through the guide component 34, the guide component 34 disengages from the first diversion channel 32 and then connects to the second diversion channel 33, allowing the facing bottle caps 11 to enter the second diversion channel 33. This cycle repeats, allowing the first diversion channel 32 and the second diversion channel 33 to sequentially receive N facing bottle caps 11. The facing bottle caps 11 in the second diversion channel 33 enter the flipping channel 352 from the upper channel 351, causing the facing bottle caps 11 to be flipped into facing backwards bottle caps 12. The facing backwards bottle caps 12 return to the second diversion channel 33 through the lower channel 353. The facing bottle caps 11 in the first diversion channel 32 and the facing backwards bottle caps 12 in the second diversion channel 33 are conveyed to the case packer 40. The case packer 40 is used to place the front-facing bottle caps 11 and the back-facing bottle caps 12 into the case 90 in sequence, so that the front-facing bottle caps 11 and the back-facing bottle caps 12 are arranged alternately from top to bottom in the case 90. In the case 90, the front of the bottle cap abuts against the front of the bottle cap in the adjacent layer, and the back of the bottle cap abuts against the back of the bottle cap in the adjacent layer, so that the bottle caps are stably abutted against each other and are not easy to slide against each other, thereby improving the stability of the bottle caps placed in the case 90 and thus avoiding the bottle caps from shifting, sliding or flipping during transportation.

[0039] In some optional embodiments, the guide assembly 34 includes a support beam 341, a first telescopic assembly 342, a first connecting rod 343, two second connecting rods 344, and two guide rods 345. The support beam 341 is mounted on the second conveying mechanism 30. The two second connecting rods 344 are rotatably connected to the support beam 341. The first connecting rod 343 is rotatably connected to the two second connecting rods 344 respectively, so that the support beam 341, the first connecting rod 343, and the two second connecting rods 344 together form a parallelogram structure. The first telescopic assembly 342 is mounted on the support beam 341, and its telescopic end is rotatably connected to one of the second connecting rods 344. The guide rods 345 are correspondingly connected to the second connecting rods 344. A guide channel 346 communicating with the conveying channel 31 is formed between the two guide rods 345. The first telescopic assembly 342 drives the second connecting rods 344 to rotate, thereby driving the guide rods 345 to rotate, so that the guide channel 346 communicates with the first diversion channel 32 or the second diversion channel 33. N bottle caps 11 facing forward in the conveying channel 31 are conveyed to the first diversion channel 32 through the guide channel 346. Then, the output end of the telescopic component extends to drive the second connecting rod 344 to rotate, so that the guide rod 345 rotates, thereby driving the guide channel 346 to rotate to connect with the second diversion channel 33. Then, the N bottle caps 11 facing forward in the conveying channel 31 are conveyed to the second diversion channel 33 through the guide channel 346, and so on.

[0040] The structure of the first telescopic component 342 can be selected according to actual needs. In some optional embodiments, the first telescopic component 342 is a cylinder, an electric cylinder, or a hydraulic cylinder. In this application, the first telescopic component 342 is a cylinder, and its piston rod is rotatably connected to the second connecting rod 344.

[0041] In some alternative embodiments, a universal joint bearing 347 is provided on one of the second connecting rods 344, and the output end of the first telescopic assembly 342 is rotatably connected to the second connecting rod 344 through the universal joint bearing 347, thereby improving the smoothness of transmission.

[0042] In some optional embodiments, a counter 311 is provided on one side of the conveying channel 31, and the counter 311 is signal-connected to the first telescopic component 342. The counter 311 is used to record the number of bottle caps that pass through the conveying channel 31 and enter the guide channel 346. Whenever the number of bottle caps that pass through the conveying channel 31 and enter the guide channel 346 reaches a preset number, such as 12, the counter 311 sends a signal to the first telescopic component 342. The first telescopic component 342 is activated to drive the second connecting rod 344 to rotate, thereby causing the guide channel 346 to switch to a connecting diversion channel, so as to facilitate the equal diversion of bottle caps into the first diversion channel 32 and the second diversion channel 33.

[0043] In some alternative embodiments, the counter 311 is an infrared counter 311. The counting principle of the infrared counter 311 is well known to those skilled in the art, and therefore will not be described in detail here. Of course, the structure of the counter 311 is not limited to this, and those skilled in the art can choose other suitable structures according to the teachings of this invention.

[0044] Please see Figure 5 and Figure 6 , Figure 5 This is a partial structural schematic diagram of one side of the first and second conveying mechanisms according to an embodiment of the present invention. Figure 6 This is a schematic diagram of the deceleration mechanism and one side of the bottle cap according to one embodiment of the present invention. In some optional embodiments, the blowing mechanism 50 includes a deceleration mechanism and a blower 52. The deceleration mechanism includes a plurality of deceleration rollers 51 disposed between the first conveying mechanism 20 and the second conveying mechanism 30. The plurality of deceleration rollers 51 are arranged sequentially from the first conveying mechanism 20 to the second conveying mechanism 30 and are rotatably connected to the first conveying mechanism 20. The blower 52 is disposed on one side of the plurality of deceleration rollers 51 and is used to blow air onto the bottle cap on the first conveying mechanism 20 and the plurality of deceleration rollers 51.

[0045] Bottle caps 11 produced by the bottle cap injection molding device 10 are sequentially transported to the first conveying mechanism 20. Since there is a production interval between the bottle caps 11 produced by the bottle cap injection molding device 10, each bottle cap 11 reaches the deceleration mechanism in sequence at a preset interval time. The preset interval time is usually a few seconds, such as 3 seconds. After the first positively oriented bottle cap 11 is conveyed to the reduction roller 51 by the first conveying mechanism 20, the positively oriented bottle cap 11 stays on the reduction roller 51 and is blown by the blower 52. When the second positively oriented bottle cap 11 reaches the reduction roller 51, the first positively oriented bottle cap 11 is pushed by the second positively oriented bottle cap 11 and passes over the reduction roller 51 and enters the second conveying mechanism 30. Then, the second conveying mechanism 30 conveys it to the next process or the positively oriented bottle cap 11 case packing machine 40. The second positively oriented bottle cap 11 stays on the reduction roller 51 and is blown until the third positively oriented bottle cap 11 pushes the second positively oriented bottle cap 11 to the second conveying mechanism 30. This cycle is repeated so that the positively oriented bottle cap 11 can stay next to the blowing mechanism 50 for a certain period of time, thereby improving the blowing effect of the positively oriented bottle cap 11.

[0046] The number of reduction rollers 51 can be selected according to actual needs. In some optional embodiments, at least three reduction rollers 51 are provided between the first conveying mechanism 20 and the second conveying mechanism 30.

[0047] To ensure that bottle caps are held on multiple deceleration rollers 51, in some optional embodiments, the distance between the deceleration roller 51 closest to the first conveying mechanism 20 and the deceleration roller 51 closest to the second conveying mechanism 30 is no greater than three-fifths and no less than one-third of the bottle cap's diameter. Of course, if a longer purging time is required, the distance between the deceleration roller 51 closest to the first conveying mechanism 20 and the deceleration roller 51 closest to the second conveying mechanism 30 can be adjusted to be more than twice the bottle cap's diameter, allowing more bottle caps to remain on the deceleration mechanisms.

[0048] In this embodiment, the height of the top of the deceleration roller 51 is higher than the height of the conveying surface of the first conveying mechanism 20, making it easier for the bottle cap to stay on the deceleration roller 51 and detach from the first conveying mechanism 20.

[0049] In some optional embodiments, a support beam 21 is provided above the first conveying mechanism 20, and a capping rod 22 is provided on the support beam 21. The capping rod 22 is rotatably connected to the support beam 21 and can rotate up and down relative to the support beam 21. The capping rod 22 prevents the bottle caps from tilting up when they push against each other and prevents the edges of the bottle caps from getting stuck between adjacent reduction rollers 51 and tilting up. The up and down rotation of the capping rod 22 relative to the support beam 21 can adjust the height of the capping rod 22, thereby adapting to bottle caps of different heights.

[0050] In some optional embodiments, the first conveying mechanism 20 is a chain conveyor. In some optional embodiments, the second conveying mechanism 30 is a belt conveyor. Of course, the first conveying mechanism 20 and the second conveying mechanism 30 can also adopt other types of conveying mechanisms. The structure and principle of belt conveyors and chain conveyors are well known to those skilled in the art and will not be described in detail here.

[0051] Please see Figure 7This is a cross-sectional view of the first conveying mechanism, visual inspection mechanism, rejection mechanism, and waste box according to one embodiment of the present invention. In some optional embodiments, the bottle cap production chain further includes: a visual inspection mechanism 60, a rejection mechanism 70, and a waste box 80; the visual inspection includes a movable support frame 61, a CCD industrial camera 62, a ring light source 63, and an image processing module. The movable support frame 61 is disposed on one side of the first conveying mechanism 20, and the CCD industrial camera 62 and the ring light source 63 are disposed on the movable support frame and located above the first conveying mechanism 20. The first conveying mechanism 20 and the ring light source 63 are arranged sequentially from top to bottom. The image processing module is connected to the CCD industrial camera 62 via signal. The rejection mechanism 70 includes a second telescopic component 71 and a pusher plate 72. The second telescopic component 71 is located on one side of the first conveying mechanism 20 and is also connected to the image processing module via signal. The pusher plate 72 is connected to the output end of the second telescopic component 71. The waste box 80 is located on the side of the first conveying mechanism 20 away from the second telescopic component 71. The pusher plate 72 pushes the bottle caps on the first conveying mechanism 20 into the waste box 80 under the drive of the second telescopic component 71. The CCD industrial camera 62 is used to acquire images of bottle caps in the bottle cap conveying channel 31. The image processing module determines whether the appearance of the bottle cap is qualified based on the difference between the bottle cap image and the standard image. If the appearance of the bottle cap is unqualified, the image processing module sends a rejection signal to the telescopic component. The output end of the telescopic component extends, causing the pusher plate 72 to drive the unqualified bottle caps in the bottle cap conveying channel 31 into the waste box 80, thereby realizing automatic rejection of unqualified bottle caps, improving production efficiency, and ensuring structural stability. The vision inspection mechanism 60 can also be moved to a suitable position for inspection according to the actual production line.

[0052] The structure of the second telescopic component 71 can be selected according to actual needs. In some optional embodiments, the second telescopic component 71 is a cylinder, an electric cylinder, or a hydraulic cylinder. In this application, the second telescopic component 71 is a cylinder, and its piston rod is connected to the push plate 72 in a driving connection.

[0053] Please see Figure 8This is a schematic diagram of a case packing machine according to an embodiment of the present invention. In some optional embodiments, the case packing machine 40 includes two cap arranging mechanisms 41 and a clamping mechanism 42. The two cap arranging mechanisms 41 are respectively connected to the first diversion channel 32 and the second diversion channel 33. One cap arranging mechanism 41 is used to arrange the positively facing bottle caps 11 into an array of positively facing bottle caps 11, and the other cap arranging mechanism 41 is used to arrange the negatively facing bottle caps 12 into an array of negatively facing bottle caps 12. The clamping mechanism 42 is used to clamp the array of positively facing bottle caps 11 and the array of negatively facing bottle caps 12 sequentially into the box body 90, so that the array of positively facing bottle caps 11 and the array of negatively facing bottle caps 12 in the box body 90 are arranged alternately from top to bottom. Since bottle caps are usually arranged in an array and then clamped and placed into the box body 90, the structure and principle of the cap arranging mechanism 41 and the clamping mechanism 42 are well known to those skilled in the art and will not be described in detail here.
