Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging machinery and equipment, and in particular to a lid-scraping device and method. Background Technology

[0002] Cap sorting devices are commonly used in beverage bottling and pharmaceutical manufacturing. These devices organize disorganized bottle caps into relatively fixed positions with consistent orientation before feeding them into the production line for loading onto bottles. Currently, visual inspection is typically used to detect caps with incorrect orientation, and then robotic arms or nozzles are intermittently controlled to remove them. This method is complex, relatively costly, and visual inspection is challenging, especially for irregularly shaped caps, leading to risks of missed or incorrect removal and a low cap sorting pass rate.

[0003] US Patent No. US9592968B2 discloses a method for aligning bottle caps during transport. This method uses nozzles to spray air to adjust the direction of the bottle caps, which are then transported outwards by a conveyor after adjustment. However, this method, which adjusts the bottle cap direction using nozzles, cannot remove bottle caps with incorrect orientation, resulting in low cap sorting efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a cap-sorting device with simple structure, low cost, high cap-sorting efficiency, and high cap-sorting qualification rate. A cap-sorting method is also provided.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A cap sorting device includes a rotating chamber and a cap sorting channel. The rotating chamber includes a rotating chamber body and a cap placement plate disposed on the outer periphery of the top of the rotating chamber body. One end of the cap sorting channel is connected to the cap placement plate for entering towards qualified bottle caps, and the other end of the cap sorting channel extends to the outside of the rotating chamber for outputting bottle caps.

[0007] The cap plate is provided with a defective bottle cap return mechanism on one side. The defective bottle cap return mechanism is used to allow qualified bottle caps to pass through and blow unqualified bottle caps back into the rotating chamber.

[0008] The defective bottle cap return mechanism includes a cover baffle and an air blower. The air blower is used to blow bottle caps on the cover plate into the rotating chamber. The cover baffle is used to push defective bottle caps toward the rotating chamber and block qualified bottle caps from being blown into the rotating chamber by the air blower.

[0009] As a further improvement to the above technical solution:

[0010] The cover has a protrusion, and there is a height difference between the protrusion and the cover plate. A cover channel is formed between the protrusion and the cover plate. The cover channel is used to allow a bottle cap with the correct orientation to pass through and to limit the orientation of the bottle cap.

[0011] The cover is located on the side above the cover plate away from the rotating chamber, and the air blowing component is located on the side above the cover plate close to the rotating chamber.

[0012] The cap placement plate is also provided with an air blowing mechanism on one side, which is used to blow bottle caps from the cap placement plate into the rotating chamber when the cap handling channel does not need to be filled with caps.

[0013] Along the cap conveying direction, the air blowing mechanism is located upstream of the cap sorting channel and / or the unqualified cap return mechanism.

[0014] The rotating chamber is also equipped with a cap blowing mechanism in the middle, which is used to blow bottle caps from inside the rotating chamber onto the cap plate.

[0015] The blowing mechanism includes an air blowing component, a hanger, a rotating seat, and a movable seat. The hanger is fixedly installed above the rotating chamber. The rotating seat is rotatably and adjustablely installed on the hanger. The movable seat is movably and adjustablely installed on the rotating seat. The air blowing component is installed on the movable seat.

[0016] The rotating chamber is also equipped with a missing lid detection mechanism, which is used to detect whether the rotating chamber is missing a lid. The missing lid detection mechanism includes a mounting base, a detection plate and a proximity switch. The mounting base is fixed above the rotating chamber. The detection plate is mounted on the mounting base and can swing up and down. The proximity switch is mounted on the mounting base and is arranged correspondingly to the detection plate.

[0017] The rotating chamber is equipped with a guide cap mechanism, which is used to gather bottle caps inside the rotating chamber.

[0018] The cap feeding channel is equipped with an accelerating air blowing mechanism, which blows air along the discharge direction of the cap feeding channel to accelerate the discharge of bottle caps.

[0019] The discharge port of the cover channel is connected to a discharge guide rail, and the discharge guide rail is equipped with a vibration component.

[0020] To solve the above-mentioned technical problems, the present invention also provides a method for the above-mentioned lid-scraping device to perform lid-scraping, comprising:

[0021] Place the bottle cap into the rotating chamber of the rotating chamber;

[0022] The rotating chamber is driven by a drive device. The rotation speed of the rotating chamber is adjusted so that the bottle cap can enter the cap plate under the action of centrifugal force, and the bottle cap can enter the cap channel as the cap plate rotates.

[0023] Adjust the air volume of the air blowing component so that the positive cover on the cover plate can stay on the cover plate when passing through the cover blocking channel, while the reverse cover and the inverted cover are blown back into the rotating chamber before entering or passing through the cover blocking channel.

[0024] Compared with the prior art, the advantages of the present invention are as follows:

[0025] The cap sorting device of the present invention comprises a cap-returning mechanism for defective caps, consisting of a cap-blocking component and an air-blowing component. Its simple structure allows caps facing out of orientation to be rejected and returned to the storage compartment for re-capping without the need for orientation adjustment on the cap plate, resulting in high sorting efficiency. The cap-returning process is simple and cost-effective, as the pushing and / or blowing action of the cap-blocking component prevents caps facing out of orientation from being missed. Furthermore, the cap-blocking component also guides and limits correctly oriented caps to prevent them from being blown into the rotating compartment by the air-blowing component, further preventing rejection and resulting in a low error rate and a high cap sorting pass rate.

[0026] The cap sorting method of the present invention enables the cap sorting device to process bottle caps efficiently and stably, and the processed bottle caps can be output to the place where bottle caps are needed in a specific orientation. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] In the description of this invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] Furthermore, 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] like Figures 1 to 7As shown, the cap sorting device of this embodiment includes a rotating chamber 1 and a cap sorting channel 2. The rotating chamber 1 includes a rotating chamber body 11 and a cap placement plate 12 disposed on the outer periphery of the top of the rotating chamber body 11. One end of the cap sorting channel 2 is connected to the cap placement plate 12 and is used to allow qualified bottle caps 100 to enter. The other end of the cap sorting channel 2 extends to the outside of the rotating chamber 1 and is used to output bottle caps 100.

[0042] A defective bottle cap return mechanism 3 is provided on one side of the cover plate 12. The defective bottle cap return mechanism 3 is used to allow the qualified bottle cap 100 to pass through and blow the defective bottle cap 100 back into the rotating chamber 11.

[0043] The defective bottle cap return mechanism 3 includes a cover member 31 and an air blowing member 32. The air blowing member 32 is used to blow the bottle caps 100 on the cover plate 12 into the rotating chamber 11. The cover member 31 is used to push the defective bottle caps 100 toward the rotating chamber 11 and block the qualified bottle caps 100 toward the rotating chamber 11 to prevent them from being blown into the rotating chamber 11 by the air blowing member 32.

[0044] In this embodiment, it can be applied to a type such as Figure 9The irregularly shaped bottle cap 100 shown (such as a gourd cap) includes a cap post 101 and a cap bottom 102 located at the bottom of the cap post 101. The cap bottom 102 protrudes from the periphery of the cap post 101. Taking this irregularly shaped bottle cap 100 as an example to illustrate the cap-handling process, the bottle cap 100 has three states on the cap plate 12: upright (cap bottom 102 facing down, which is acceptable); reversed (cap bottom 102 facing up, which is unacceptable); and tilted (cap 100 tilted, which is unacceptable). In this embodiment, the cap sorting device places multiple bottle caps 100 to be sorted into a rotating chamber 11 during the sorting process. The rotating chamber 11 rotates, and the bottle caps 100 gradually move onto the cap placement plate 12 under the action of centrifugal force. When the bottle caps 100 on the cap placement plate 12 are rotated and conveyed to the unqualified bottle cap return mechanism 3, the unqualified bottle caps 100 are pushed and blown into the rotating chamber 11 by the pushing action of the cap baffle 31 and / or the blowing action of the air blower 32. The upper surface of the bottom edge 102 of the qualified bottle caps 100 is not affected by the blowing action of the air blower 32 under the blocking action of the cap baffle 31, and continues to be conveyed by the rotating cap placement plate 12, enters the cap sorting channel 2, and is output outward as qualified bottle caps 100. In this embodiment, the cap sorting device comprises a cap retainer 31 and an air blower 32. The structure is simple; caps 100 facing out of orientation are removed by the cap sorting device 3 and returned to the rotating chamber 11 for re-sealance, eliminating the need to adjust the orientation on the cap plate 12, resulting in high sorting efficiency. The cap retainer 31 pushes and / or the air blower 32 blows the caps 100 back into the rotating chamber 11, simplifying the process and reducing costs. The pushing and / or blowing action prevents caps 100 from being missed, resulting in a low miss rate. Furthermore, the cap retainer 31 also guides and limits caps 100 facing out of orientation to prevent them from being blown into the rotating chamber 11 by the air blower 32, further preventing rejection and resulting in a low error rate and high sorting success rate.

[0045] Furthermore, such as Figure 2As shown, in this embodiment, the cover member 31 has a protrusion, and there is a height difference between the protrusion and the cover plate 12. A cover channel 33 is formed between the protrusion and the cover plate 12. The cover channel 33 is used to allow the qualified bottle cap 100 to pass through and to limit the qualified bottle cap 100. When the qualified bottle cap 100 is transported to the cover member 31, since the height of the cover channel 33 matches the thickness of the cap bottom 102 of the qualified bottle cap 100, that is, one edge of the cap bottom 102 of the qualified bottle cap 100 can just enter and pass through the cover channel 33. When the air blowing member 32 blows air, one edge of the cap bottom 102 of the qualified bottle cap 100 is in the cover channel 33, and the upper surface of the cap bottom 102 of the qualified bottle cap 100 can be... The lower edge of the protrusion blocks the airflow from blowing it into the rotating chamber 11. When a misaligned bottle cap 100 is conveyed to the baffle 31, due to the limited height of the baffle channel 33, the misaligned bottle cap 100 cannot enter the baffle channel 33. The protrusion of the baffle 31 contacts part of the misaligned bottle cap 100, thereby pushing the misaligned bottle cap 100 and preventing it from getting stuck in the baffle channel 33. The baffle 31 can both push the misaligned bottle cap 100 and limit the aligned bottle cap 100, making its structure simple and reasonable.

[0046] Preferably, in this embodiment, a fixed wall is also fixedly provided on the outer periphery of the cover plate 12, which can prevent the bottle cap 100 from being thrown out of the cover plate 12 under the action of centrifugal force during the rotation and conveying process on the cover plate 12.

[0047] Specifically, in this embodiment, when the inverted cap is conveyed to the baffle 31, the bottom 102 of the inverted cap cannot enter the baffle channel 33 due to its tilt. The bottom 102 of the inverted cap contacts the side of the protrusion. Some of the inverted caps fall into the rotating chamber 11 before being conveyed to the air blowing component 32 due to the pushing action of the protrusion of the baffle 31 or the instability of the center of gravity during the conveying process. The remaining inverted caps are blown into the rotating chamber 11 by the air blowing action of the air blowing component 32. Figure 8 As shown, when the reversed cover is conveyed to the cover member 31, the bottom 102 of the reversed cover cannot enter the cover channel 33 because it is facing upward. Some reversed covers fall into the rotating chamber 11 before being conveyed to the air blowing member 32 due to the pushing of the fixed wall or the unstable center of gravity during the conveying process. The remaining reversed covers are blown into the rotating chamber 11 by the air blowing action of the air blowing member 32.

[0048] Preferably, such as Figure 7As shown, in this embodiment, the height of the air outlet of the air blowing component 32 (the distance between the air outlet and the cap plate 12) is less than the thickness of the bottle cap 100 (i.e., the maximum distance from the end face of the cap bottom 102 to the end face of the cap post 101) and greater than the thickness of the cap bottom 102. The air blowing component 32 and the cap-blocking component 31 form a channel that allows only the cap post 101 to pass through, ensuring that only qualified bottle caps 100 can pass through, preventing unqualified bottle caps 100 from passing through and being rejected, thus reducing the rejection rate. Of course, as... Figure 8 As shown, in other embodiments, the height of the air outlet of the air blowing component 32 can also be greater than the thickness of the bottle cap 100. The blowing force of the air blowing component 32 can be applied to the bottle cap 100 better, resulting in a better rejection effect. It can also prevent the bottle cap 100 from getting stuck between the air blowing component 32 and the cover component 31, causing congestion of the upstream bottle cap 100.

[0049] Preferably, in this embodiment, the air outlet of the air blowing component 32 is located at the end of the baffle channel 33. The portion of the qualified bottle cap 100 that is facing the baffle channel 33 is pressed by the protrusion at the end, making the positioning more stable; while the portion of the unqualified bottle cap 100 that is facing the baffle channel 33 is squeezed out at the end, making it easier for the unqualified bottle cap 100 to be blown into the rotating chamber 11, which is a reasonable structure.

[0050] Preferably, in this embodiment, the protrusion is wedge-shaped, and the width of the protrusion gradually increases along the conveying direction of the bottle cap 100. When the unqualified bottle cap 100 is conveyed to the stop member 31, the unqualified bottle cap 100 is gradually pushed, and the pushing process is stable; when the qualified bottle cap 100 is conveyed to the stop member 31, as the conveying distance of the qualified bottle cap 100 gets closer and closer to the air blowing member 32, more and more of the edge of the cap bottom 102 is pressed by the protrusion, and the qualified bottle cap 100 is pressed more and more stably, making it less likely to be rejected, and the rejection rate is lower.

[0051] Preferably, in this embodiment, the width of the baffle channel 33 is narrow (the maximum width of the baffle channel 33 is 1 / 10 to 1 / 4 of the width of the cap plate 12), which is only wide enough to enter the bottom edge 102 of the qualified bottle cap 100, while other parts of the bottle cap 100 cannot enter. This can specifically limit the movement towards the qualified bottle cap 100. The less the bottle cap 100 is stuck, the less interference occurs between the bottle cap 100 and the baffle channel 33, and the less likely the normal movement towards the qualified bottle cap 100 is affected, resulting in higher stability.

[0052] Preferably, in this embodiment, a baffle plate (not shown in the figure) is provided upstream of the unqualified bottle cap return mechanism 3. The baffle plate is inclined along the conveying direction of the bottle cap 100. When the bottle cap 100 in the rotating chamber 11 moves to the cap placement plate 12, the bottle cap 100 may form two or more parallel rows. By guiding the bottle cap 100 on the cap placement plate 12 through the baffle plate, the bottle cap 100 is gathered into a row, so that when the bottle cap 100 on the cap placement plate 12 is conveyed to the unqualified bottle cap return mechanism 3, it is a single row of continuous bottle caps 100. This makes the actual width of the cap placement plate 12 downstream of the baffle plate similar to the bottom diameter of the bottle cap 100. The unqualified bottle cap 100 is less likely to stay on the cap placement plate 12, reducing the rejection pressure of the unqualified bottle cap return mechanism 3 on the unqualified bottle cap 100. Preferably, in this embodiment, a fixed wall is also fixedly provided on the outer periphery of the cover plate 12, which can prevent the bottle cap 100 from being thrown out of the cover plate 12 under the action of centrifugal force during the rotation and conveying process on the cover plate 12.

[0053] Furthermore, such as Figure 2 As shown, in this embodiment, the cover 31 is located on the side above the cover plate 12 away from the rotating chamber 11, and the air blowing component 32 is located on the side above the cover plate 12 close to the rotating chamber 11, so that the pushing force and blowing force on the unqualified bottle cap 100 can both be directed towards the rotating chamber 11, which is a reasonable layout.

[0054] Furthermore, such as Figure 2 As shown in this embodiment, an air blowing mechanism 4 is also provided on one side of the cap plate 12. The air blowing mechanism 4 is used to blow the bottle caps 100 on the cap plate 12 into the rotating chamber 11 when the cap sorting channel 2 does not need to be filled with caps. When the cap sorting channel 2 is full or the downstream discharge equipment needs to be temporarily stopped due to failure or other reasons, the air blowing mechanism 4 is opened to blow all the bottle caps 100 that are about to enter the cap sorting channel 2 into the rotating chamber 11, preventing the bottle caps 100 from being blocked due to not being able to be discharged, and maintaining the continuous operation of the rotating chamber 1. When the downstream equipment is restored and caps need to be filled again, the air blowing mechanism 4 can be closed to immediately resume the operation without waiting for the rotating chamber 1 to be restarted, thus ensuring high work continuity. Preferably, along the conveying direction of the bottle caps 100, the air blowing mechanism 4 is located upstream of the cap sorting channel 2 and the unqualified bottle cap return mechanism 3. Before the bottle caps 100 enter the unqualified bottle cap return mechanism 3, all bottle caps 100 are blown back into the rotating chamber 11, which can reduce the repetitive work of the unqualified bottle cap return mechanism 3, reduce equipment wear and tear, and make the operation process reasonable.

[0055] Furthermore, such as Figures 3 to 5As shown, in this embodiment, a capping mechanism 5 is also provided in the middle of the rotating chamber 11. The capping mechanism 5 is used to blow the bottle caps 100 inside the rotating chamber 11 onto the capping plate 12. The capping mechanism 5 delivers the bottle caps 100 onto the capping plate 12 by blowing air, in conjunction with the centrifugal force of the rotating chamber 1, resulting in higher capping efficiency. Preferably, in this embodiment, the bottom of the rotating chamber 11 is connected to the capping plate 12 by an inclined transition plate, resulting in a smooth transition and easier capping.

[0056] Furthermore, in this embodiment, the capping mechanism 5 includes an air-blowing component 51, a hanger 52, a rotating seat 53, and a movable seat 54. The hanger 52 is fixedly mounted above the rotating chamber 11, the rotating seat 53 is rotatably and adjustablely mounted on the hanger 52, and the movable seat 54 is movably and adjustablely mounted on the rotating seat 53. The air-blowing component 51 is mounted on the movable seat 54. By setting the rotating seat 53 and the movable seat 54, the air-blowing direction and height of the air-blowing component 51 can be flexibly adjusted, adapting to different numbers of bottle caps 100 within the rotating chamber 11, thus exhibiting strong adaptability.

[0057] Preferably, in this embodiment, the air blowing component 51 is an air blowing nozzle, which is provided with multiple air blowing channels so that the airflow acts on the bottle cap 100 more comprehensively.

[0058] Preferably, in this embodiment, the rotation axis of the rotating seat 53 is parallel to the rotation plane of the rotating chamber 1, so that the air blowing direction of the air blowing component 51 can be adjusted up and down.

[0059] Furthermore, such as Figure 6 As shown in this embodiment, the rotating chamber 11 is also equipped with a missing cap detection mechanism 6. The missing cap detection mechanism 6 is used to detect whether there are missing caps in the rotating chamber 11. The missing cap detection mechanism 6 includes a mounting base 61, a detection plate 62, and a proximity switch 63. The mounting base 61 is fixed above the rotating chamber 11. The detection plate 62 is swayably mounted on the mounting base 61. The proximity switch 63 is mounted on the mounting base 61 and is arranged correspondingly to the detection plate 62. When there are few bottle caps 100 inside the rotating chamber 11, the detection plate 62 will swing down and approach the proximity switch 63 due to its own weight. After a period of sensing, the proximity switch 63 will issue an alarm to remind the staff to add caps to the rotating chamber 11.

[0060] Furthermore, such as Figure 4 As shown, in this embodiment, a guide cap mechanism 8 is provided inside the rotating chamber 11. The guide cap mechanism 8 is used to gather the bottle caps 100 inside the rotating chamber 11. Through the gathering effect of the guide cap mechanism 8 on the bottle caps 100 inside the rotating chamber 11, the bottle caps 100 can be better blown onto the caps by the capping mechanism 5, resulting in higher capping efficiency. Specifically, the guide cap mechanism 8 gathers the bottle caps 100 towards the blowing point of the capping mechanism 5.

[0061] Furthermore, such as Figure 4 As shown, in this embodiment, the cap feeding channel 2 is provided with an accelerating air blowing mechanism 9. The accelerating air blowing mechanism 9 blows air along the discharge direction of the cap feeding channel 2 to accelerate the discharge of bottle caps 100. By blowing air onto the bottle caps 100 in the cap feeding channel 2 through the accelerating air blowing mechanism 9, the discharge of bottle caps 100 can be accelerated, resulting in higher cap discharge efficiency.

[0062] Furthermore, such as Figure 1 As shown, in this embodiment, the outlet of the cap sorting channel 2 is connected to a discharge guide rail 7, and a vibration component 71 is provided on the discharge guide rail 7. When the sorted bottle caps 100 are being conveyed, the vibration component 71 vibrates to prevent the bottle caps 100 from interfering with each other on the discharge guide rail 7 and causing jamming.

[0063] Furthermore, the present invention also provides a method for the above-mentioned cap sorting device to sort caps, the method comprising: placing bottle caps 100 into the rotating chamber 11 of the rotating chamber 1; driving the rotating chamber 11 to rotate using a driving device, adjusting the rotation speed of the rotating chamber 11 so that the bottle caps 100 can enter the cap placement plate 12 under the action of centrifugal force, and allowing the bottle caps 100 to enter the cap blocking channel 33 as the cap placement plate 12 rotates; adjusting the blowing volume of the air blowing component 32 so that the upright caps on the cap placement plate 12 can stay on the cap placement plate 12 when passing through the cap blocking channel 33 and are not blown back into the rotating chamber 11, and that the reversed caps and inverted caps are blown back into the rotating chamber 11 before entering the cap blocking channel 33 or when passing through the cap blocking channel 33. This method enables the cap sorting device to process bottle caps 100 efficiently and stably, and the processed bottle caps 100 can be output to the place where bottle caps 100 are needed in a specific orientation.

[0064] Furthermore, when bottle caps are not needed, the air inlet valve of the air blowing mechanism 4 is opened, causing the bottle caps 100 on the cap plate 12 to be blown back into the rotating chamber 11 as they pass through the air blowing mechanism 4. Through the operation of the air blowing mechanism 4, the cap sorting mechanism can be prevented from outputting bottle caps without stopping the rotation of the rotating chamber 11. Since the rotating chamber 11 continues to rotate, the capping of the cap plate 12 can proceed normally. Therefore, this method avoids the impact of stopping the rotating chamber 11 on the equipment, and simultaneously, when bottle caps 100 need to be input from the outside, they are promptly sorted and output.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention using the methods and techniques disclosed above, or modify them into equivalent embodiments with equivalent changes, without departing from the spirit and technical essence of the present invention. Therefore, any simple modifications, equivalent substitutions, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solutions of the present invention shall still fall within the protection scope of the technical solutions of the present invention.
