Description

Technical Field

[0001] The invention belongs to the technical field of Chinese medicine ointment production equipment, and in particular relates to a Chinese medicine ointment canned product detection device. Background Art

[0002] Chinese medicine ointment is a general term for paste-like medicines in traditional Chinese medicine. Different Chinese medicine ointments have different packaging forms, and the packaging forms are roughly divided into stickers, bags, cans and bulk. Among them, canned products of Chinese medicine ointments need to go through cleaning, drying, filling, sealing, capping, stickering, labeling and testing on the production line.

[0003] At present, in the actual production of canned products of Chinese medicine ointments, most of the transparent glass jars or dark glass jars are used. Their quality will be screened before they are put on the production line, especially the integrity of the jar mouth. However, after a series of subsequent processes, especially after filling, some parts of the jar mouth edge will be damaged, which will affect the quality of the subsequent pressing of the sealing paper on the top of the jar mouth. Generally speaking, industrial cameras can be used in industrial production to capture the surface morphology of physical objects to detect product defects. However, for canned Chinese medicine ointment products, transparent glass or dark materials are used as a whole, which places high requirements on industrial cameras and may lead to missed detection and false detection, especially when there is ointment hanging on the mouth of the jar. Once the sealing paper is pressed on later, these mouth defects are difficult to find, which has a certain impact on the sealing of the product. In addition, the existing filling lines generally use multiple filling nozzles for simultaneous filling to improve the efficiency of the production line, mostly 5 to 8 filling nozzles. The filling machine comes with a liquid level detector that can detect the filling liquid level during the filling process. However, for products that are out of material and continue to be transported along the production line, there is a lack of secondary detection procedures, and online staff need to manually take them away. There is a lack of corresponding detection and exit mechanism, which affects production efficiency on the one hand and product quality on the other. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear below, they only indicate that the upper, lower, left and right directions are consistent with the accompanying drawings themselves, and do not limit the structure.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0036] Examples, such as Figure 1 As shown in FIG. 12 , a device for detecting canned products of Chinese medicine ointment provided by the present invention comprises a detection frame 2, wherein the detection frame 2 is a horizontal cylindrical structure and a conveyor line 1 for conveying canned products 9 passes through the inside thereof, a transmission frame 3 is arranged inside the detection frame 2, an angle adjustment mechanism 4 cooperating with the transmission frame 3 is arranged at the bottom of the detection frame 2, a main mounting ring beam 5 cooperating with the transmission frame 3 is arranged inside the transmission frame 3, the main mounting ring beam 5 is a regular decagonal structure and comprises ten mounting surfaces, at least six universal hinges 51 are arranged on two adjacent mounting surfaces near the top thereof, and the six universal hinges 51 are all provided with photoelectric liquid level sensors 6, The detection directions of the six photoelectric liquid level sensors 6 are toward the conveyor line 1 and correspond one to one with the six canned products 9 adjacent to each other on the conveyor line 1. The main ring beam 5 is provided with a flipping mechanism 7 on the mounting surface opposite to the photoelectric liquid level sensor 6. The flipping mechanism 7 is provided with at least six tank mouth detection mechanisms 8 in the direction toward the conveyor line 1. The six tank mouth detection mechanisms 8 are used to detect the integrity of the tank mouths of the six canned products 9 adjacent to each other on the conveyor line 1. The main ring beam 5 is provided with a visual detection device 10 on the mounting surface above the flipping mechanism 7. The visual detection device 10 feeds back the morphology of the tank mouth and the detection status of the tank mouth detection mechanism 8 through real-time images.

[0037] In order to improve the detection capability of the present device, the annular range of the detection frame 2 is larger than the cross section of the conveyor line 1, and the detection frame 2 can cover a length of the conveyor line 1 by surrounding. Since the filling machine is in the filling process (the filling equipment automatically performs equal liquid level detection), the conveyor line 1 will have a short pause gap, and the detection items provided by the present device can be carried out in the pause gap, such as the secondary liquid level detection and the tank mouth integrity detection. Furthermore, the angle adjustment mechanism 4 provided by the present invention can adjust the angle of the transmission frame 3 and the main ring beam 5. Since the main ring beam 5 provides an installation basis for the photoelectric liquid level sensor 6, the flip mechanism 7 and the tank mouth detection mechanism 8, when the angle of the main ring beam 5 is changed, the detection position of the photoelectric liquid level sensor 6 and the detection level of the tank mouth detection mechanism 8 can be adjusted, thereby enabling the present device to better adapt to production lines of different specifications, such as large tank products and small tank products.

[0038] Matching the number of filling nozzles of the filling machine, the present invention provides at least 6 photoelectric liquid level sensors 6 at one time. During each stepping action of the conveyor line 1, the stepping distance remains consistent, and the canned products 9 entering the liquid level detection range below the detection rack 2 can correspond to the photoelectric liquid level sensors 6 one by one. In this way, all the photoelectric liquid level sensors 6 of the main ring beam 5 can quickly detect the liquid levels of multiple filling products entering the detection rack 2, and the detection results are used for subsequent equipment to determine to remove the canned products 9 that are short of material in the can. After the photoelectric liquid level sensor 6 quickly detects and reports the detection results, the time interval of the online product filling is used to start the flip mechanism 7 to synchronize the multiple can mouth detection mechanisms 8 to the can mouths of multiple filling products. Starting the can mouth detection mechanism 8 can complete the detection of the integrity of the can mouth. Optimally, the detection results obtained by the can mouth detection mechanism 8 through mechanical action, combined with the existing image and visual detection device 10 to detect the surface morphology of the can mouth, reduce the probability of false detection and missed detection of pure visual detection equipment, which is conducive to improving the quality of the filled products and the production efficiency of the production line. Therefore, the present invention is beneficial to improving the mouth detection performance of canned products, has a detection and exit mechanism for insufficient products, and improves production efficiency.

[0039] In order to improve the mobile detection efficiency of the tank mouth detection mechanism 8, the tank mouth detection mechanism 8 provided by the present invention includes a tank mouth adapter 81, an annular groove 82 is arranged inside the tank mouth adapter 81, and a plurality of contact code members 83 distributed in a circular array and contacting in sequence in the circumferential direction are arranged in the annular groove 82, the contact code member 83 is made of elastic material and can produce compression deformation under pressure, a support spring 84 is arranged between the contact code member 83 and the annular groove 82, a V-shaped code contact surface 831 for cooperating with the tank mouth is arranged on the bottom surface of the contact code member 83, a brake groove 832 is arranged in the middle of the top surface of the contact code member 83, and conductive sheets 833 fixed mainly in the form of welding are arranged on both sides of the brake groove 832, and the conductive sheets 833 on adjacent contact code members 83 contact and dock with each other, and a battery and an alarm light 85 connected in series with all the conductive sheets 833 are arranged on the tank mouth adapter 81, and the conductive sheets 833 have a certain thickness, and when they move downward for a short distance, the adjacent conductive sheets 833 can be staggered to achieve a circuit breaker. In cooperation with the contact code member 83, a brake code member 86 is provided in the brake groove 832 and passes through the tank mouth adapter 81 upward. All of the brake code members 86 are distributed in a circular array, and the top surface of the brake code member 86 is a conical surface. A rotating pressure member 87 that is nested and cooperates with the tank mouth adapter 81 is provided above the brake code member 86, and a pressure ball 871 that is used to cooperate with the top surface of the brake code member is provided at the bottom of the rotating pressure member 87. A driving component 88 for driving the rotating pressure member 87 is provided at the top center of the tank mouth adapter 81.

[0040] Specifically, the caliber of the can mouth adapter 81 is slightly larger than the caliber of the can mouth of the canned product 9 to be inspected, and the contact code member 83 inside it can be synchronously lowered and stuck on the edge of the can mouth under the action of the brake code and the rotating pressurizing member 87, and the driving assembly 88 drives the rotating pressurizing member 87 to rotate continuously. During the process that the pressurizing ball 871 rotating synchronously with the rotating pressurizing member 87 continuously sweeps over different brake code members 86, if the can mouth is not damaged, under the support of the support spring 84 and the compressibility of the contact code member 83 itself, even if the contact code member 83 swept by the pressurizing ball 871 is not damaged, The contact code member 83 also maintains a uniform level, and all the conductive sheets 833, the alarm lights 85 and the battery are always kept in the same circuit, so the alarm light 85 will not go out instantly; for the position where the tank mouth is defective, since the pressure ball 871 protrudes from the matching surface of the rotating pressure member 87 and the brake code member 86, the node swept by the pressure ball 871 will cause the contact code member 83 to be stuck at the defective node, and the circuit where the conductive sheet 833, the alarm light 85 and the battery are located will be temporarily disconnected, so the alarm light 85 will go out instantly, which can be reflected as a defect in the tank mouth.

[0041] In order to improve the accuracy of the can mouth integrity detection, considering that the can mouth has a certain thickness, in accordance with the inner and outer walls of the can mouth, the contact code member 83 provided by the present invention includes an outer ring contact body 834 and an inner ring contact body 835, the bottom of the brake code member 86 and the groove section of the brake groove 832 are both circular, the bottom of the brake code member 86 and the groove top of the annular groove 82 are in spherical contact and fit, the brake code member 86 includes an outer ring brake body 861 and an inner ring brake body 862 respectively matched with the outer ring contact body 834 and the inner ring contact body 835, and the number of the pressurizing balls 871 is two and used to contact the outer ring brake body 861 and the inner ring brake body 862 respectively. Among them, the bottom surface of the outer ring contact body 834 accounts for half of the V-code contact surface 831, the bottom surface of the inner ring contact body 835 accounts for the other half of the V-code contact surface 831, and the outer ring contact body 834 and the inner ring contact body 835 can correspond to the inner and outer edges of the can mouth respectively. Furthermore, the upper pressure ball 871 can apply pressure to the outer ring brake body 861, thereby causing the outer ring brake body 861 to apply pressure to the outer ring contact body 834. Similarly, the lower pressure ball 871 can apply pressure to the inner ring brake body 862, thereby causing the inner ring brake body 862 to apply pressure to the inner ring contact body 835. Therefore, during the continuous rotation of the rotating pressure member 87, the tank mouth detection mechanism 8 can simultaneously perform morphological detection on the integrity of the inner and outer edges of the tank mouth, thereby ensuring the accuracy of the tank mouth integrity detection.

[0042] In order to improve the utilization rate of the tank mouth adapter 81, the tank mouth adapter 81 provided by the present invention includes a ring-shaped adapter base 811, and an adapter top seat 812 connected to the adapter base 811 through a strong magnet 813 is arranged above the adapter base 811, and the annular groove 82 is located on the interface between the adapter top seat 812 and the adapter base 811. The adapter base 811 and the adapter top seat 812 can establish a quick connection relationship through the strong magnet 813, have a certain stability, and are convenient for regular maintenance of the contact code member 83 and the brake code member 86. Among them, the adapter top seat 812 includes a first conical section 812a, a cylindrical section 812b and a second conical section 812c integrally formed from top to bottom, and the cylindrical section 812b is used to support and cooperate with the rotating pressure member 87.

[0043] In order to improve the space utilization of the can mouth detection mechanism 8, the drive assembly 88 provided by the present invention is arranged in the first conical section 812a of the adapter top seat 812, and the drive assembly 88 includes a reduction steering gear 881, the output shaft of the reduction steering gear 881 is downward and is provided with a central gear 882, the transmission side of the central gear 882 is provided with a driven gear 883, the transmission side of the driven gear 883 is provided with an inner gear ring 884, and the inner gear ring 884 is connected to the rotary pressure member 87. The central gear 882 and the driven gear 883 are both arranged in the assembly structure inside the first conical section 812a. At the same time, the tooth thickness of the driven gear 883 is greater than the thickness of the inner gear ring 884, so that the rotary pressure member 87 can always maintain an effective transmission relationship with the drive assembly 88 while ensuring a certain lifting margin.

[0044] In order to improve the positioning performance of the tank mouth detection mechanism 8, the present invention adopts a cylinder-driven flipping method to control the position of the tank mouth detection mechanism 8, and the range of movement of the flipping mechanism 7 carrying the tank mouth detection mechanism 8 to flip does not interfere with the installation range of the photoelectric liquid level sensor 6. Specifically, the flipping mechanism 7 includes a swing arm 71, the swing arm 71 is connected to a support hinge 72 arranged on the transmission frame 3, a pair of driving cylinders 73 are arranged below the swing arm 71, and the telescopic end and the installation end of the driving cylinder 73 are respectively rotatably connected to the swing arm 71 and the transmission frame 3, and the swing arm 71 is provided with a bayonet that cooperates with the tank mouth detection mechanism 8 at one end facing the conveyor line 1, and a C-type positioning plate 74 is arranged on the bayonet, and the C-type positioning plate 74 is distributed around the side of the tank mouth detection mechanism 8, and a positioning connector 75 connected to the tank mouth detection mechanism 8 is arranged on the C-type positioning plate 74. Among them, the positioning connector 75 can be connected to the tank mouth adapter 81 by bolts, screws and nuts. The driving cylinder 73 drives the swing arm 71 to turn the swing arm 71 around the hinge center between the swing arm 71 and the support hinge 72, and at the same time, all the can mouth detection mechanisms 8 are turned over, such as making the can mouth detection mechanisms 8 exit the detection station synchronously and making the can mouth detection mechanisms 8 synchronously in place at the same detection level. The driving angle of the swing arm 71 by the driving cylinder 73 can be preset according to the actual height of the canned product 9.

[0045] like Figure 5As shown, in order to ensure the detection performance of the can mouth detection mechanism 8, a pressure plate 76 hinged to the can mouth detection mechanism 8 is provided below the swing arm 71 provided by the present invention and at a position close to the can mouth detection mechanism 8. The pressure plate 76 is V-shaped, one side of the pressure plate 76 is arranged between the top surface of the rotating pressure member 87 and the bottom surface of the swing arm 71, and the other side of the pressure plate 76 cooperates with the brake rod 11 obliquely arranged on the conveyor line 1. In this way, when the swing arm 71 carries all the can mouth detection mechanisms 8 to the level of the detection station, the pressure plate 76 can abut against the rod end of the brake rod 11, and the rod end of the brake rod 11 can cause the pressure plate 76 to flip around the hinge center between it and the swing arm 71, so that the rotating pressure member 87 is close to the brake code member 86, so that the top surface of the brake code member 86 generates corresponding pressure, so as to avoid the loosening of the cooperation between the brake code member 86 and the rotating pressure member 87 and affect the linkage performance of the pressure ball 871 on the brake code member 86 and the contact code member 83.

[0046] like Figure 6 As shown, in order to improve the utilization rate of the main ring beam 5, the photoelectric liquid level sensors 6 provided by the present invention are distributed in a zigzag shape on multiple installation surfaces of the transmission frame 3. Different photoelectric liquid level sensors 6 can be adjusted to different directions of canned products 9 through universal hinges 51. Adjacent photoelectric liquid level sensors 6 have sufficient adjustment margins, and the irradiation range can effectively cover all canned products 9 to be detected on a unit step length.

[0047] like Figure 5 and Figure 6 As shown, in order to improve the practicality of the transmission frame 3, the transmission frame 3 provided by the present invention includes a ring body 31, and a plurality of clamping rods 32 are arranged between the ring bodies 31. The clamping rods 32 are clamped and matched with the edge side of the main ring beam 5. The design is reasonable, the structure is simple, and bolt-free connection is required, and it is ensured that the main ring beam 5 can provide more installation planes for installing different functional devices. Further, the two end surfaces of the ring body 31 are supported on the inner wall of the detection frame 2, and a transmission ring gear 41 is arranged at the bottom of the ring body 31. An adjustment gear shaft 42 meshing with the transmission ring gear 41 is arranged below the transmission ring gear 41. An adjustment motor 43 is arranged at the power input end of the adjustment gear shaft 42. The adjustment motor 43 is used to drive the adjustment gear shaft 42. The transmission cooperation between the adjustment gear shaft 42 and the transmission ring gear 41 can drive the transmission ring gear 41 and the main ring beam 5 to rotate, thereby reaching an angle that meets the working requirements.

[0048] like Figure 1 and Figure 2As shown, since the multiple photoelectric liquid level sensors 6 inside the detection rack 2 provide a secondary liquid level detection function, as part of the screening mechanism, a screening cylinder is provided on one side of the conveyor line 1 in coordination therewith, the screening cylinder is tilted toward the conveyor line 1, and a defective product retention area connected to the conveyor line 1 is provided on the telescopic side of the screening cylinder. Under the reporting of the secondary liquid level detection result, the screening cylinder can instantly push the filling products that do not meet the standards to the defective product retention area through the telescopic action.
