Description

Technical Field

[0001] This disclosure relates to the field of tea filling equipment technology, and in particular to a step-by-step filling system. Background Technology

[0002] Currently, tea production typically involves manual bottling using specialized equipment. In the traditional tea bottling process, workers use manual or semi-automatic equipment, such as weighing scales, funnels, and manual filling machines, to dispense and fill the tea. This equipment requires manual operation to control the entire process. Workers usually rely on experience and skill to determine the appropriate amount of tea and to fill the jars evenly, ensuring the quality and appearance of the tea.

[0003] However, manually filling tea with existing equipment is slow and cannot achieve efficient production levels. Manual filling requires more time and labor, thus failing to meet the needs of large-scale production. Furthermore, due to the limitations of manual operation, it is difficult to guarantee the accuracy and consistency of each filling. This can lead to uneven tea distribution, affecting product quality and taste. In addition, manual operation is prone to fatigue and lack of concentration, potentially leading to human error. For example, failure to ensure the tea storage containers are completely clean or incorrect weighing before filling can result in resource waste and loss. Summary of the Invention

A filling valve for opening and closing the tea filling is provided at the bottom of the discharge hopper. The discharge hopper is fixedly connected to the discharge holes. A pair of U-shaped support rods corresponding to the connecting frames are fixedly connected to the upper surface of the second support. The upper surface of one of the U-shaped support rods is connected to a conveying mechanism on the second support. The position sensor is electrically connected. Multiple support blocks corresponding to the feeding bin are fixedly connected to the opposite sides of the U-shaped support rod.

[0014] Optionally, the lower surfaces of both the first and second supports are provided with multiple support legs for support.

[0015] Compared with existing technologies, the beneficial effects of this disclosure are as follows: The step-by-step filling system of this disclosure, through the design of a first support, a second support, a disinfection mechanism, a filling mechanism, and a detection mechanism, can effectively kill or remove harmful microorganisms such as bacteria, viruses, and molds from the surface of empty tea cans through a fully automated disinfection process, ensuring the hygiene and safety of the empty tea cans. This helps prevent tea contamination and reduces potential health risks. Furthermore, it ensures that empty tea cans do not introduce odors, contaminants, or impurities, thereby maintaining the original quality and taste of the tea. The cleanliness of empty tea cans has a significant impact on the quality and taste of the tea. Finally, fully automated tea filling enables high-speed and precise tea filling, improving production efficiency.

[0016] Furthermore, the step-by-step filling system disclosed herein, through the design of a first and second weighing platform, ensures that the weight of tea in each tea canister is substantially the same by weighing the empty canister and then weighing the canister again after it has been filled with tea. This helps maintain product consistency and provides consumers with the same quality and quantity of tea. In addition, weighing is an effective quality control method. If there are significant differences in weight within the tea canisters, it may indicate a problem with some canisters, such as over- or under-filling or uneven filling. By weighing again, these problems can be identified and resolved promptly, improving product quality.

[0017] Furthermore, this disclosed step-by-step filling system adjusts the flow speed and volume of tea leaves within the feed hopper through the design of a vibrating motor. If the tea leaves flow too quickly, the risk of clogging may increase; if the flow is too slow, blockage is likely to occur. By controlling the operation of the vibrating motor, the flowability of the tea leaves within the feed hopper can be adjusted to achieve optimal conditions, reducing the possibility of tea leaves getting stuck in the feed hopper.

[0032] Please see Figures 1 to 5 This disclosure provides a step-by-step filling system, including a first support 1 and a second support 3. Multiple support legs 7 are provided on the lower surfaces of both the first support 1 and the second support 3 for support. A conveyor belt 101, mounted on the first support 1, is used to transport empty tea cans. The net tea content in each empty tea can is 50g ± 5g. The first support 1 is equipped with a detection mechanism to check for impurities in the empty tea cans, and a pushing mechanism to push out cans that fail the inspection. A first weighing platform 2, installed at one end of the first support 1 and the second support 3 respectively, is used to weigh the empty tea cans.

[0035] The photoelectric sensor 104 is a sensor that can convert light signals into electrical signals for detection, measurement, and control. It achieves the detection and measurement of light through the interaction of optical components and photosensitive elements.

[0036] like Figure 1-2As shown, the pushing mechanism includes a support plate 105 connected to the outer wall of the first bracket 1. A first cylinder 106 is fixedly connected to the upper surface of the support plate 105. A movable slide groove is opened on the first bracket 1. A push plate 107 is arranged inside the movable slide groove. The push plate 107 is fixedly connected to the piston rod of the first cylinder 106. A sliding can groove 111 corresponding to the push plate 107 is opened on the first bracket 1. A first can box 108, which overlaps with the sliding can groove 111 and is used to receive defective products, is fixedly connected to the outer wall of the first bracket 1.

[0037] like Figure 2 As shown, the outer wall of the first weighing platform 2 is fixedly connected to a first support base 21 for supporting the first clamping arm 22, and the clamping end of the first clamping arm 22 is provided with a plurality of first clamping sleeves 23 corresponding to the empty tea cans placed on the conveyor belt 101.

[0038] like Figure 3-4 As shown, the disinfection mechanism includes a disinfection rack 32 connected to the second support 3. The interior of the disinfection rack 32 is equipped with an ultraviolet lamp 33 for disinfecting the empty tea canisters on the template seat 31. The ultraviolet lamp 33 is a common disinfection method for sterilization and disinfection. Its principle is to use ultraviolet radiation to inactivate bacteria, viruses and other microorganisms.

[0039] like Figure 1 , Figure 4 and Figure 5 As shown, the filling mechanism includes a pair of connecting frames 5 connected to the outer wall of the second support 3. A material loading rack 51 is fixedly connected to the upper surface of the connecting frame 5. A material loading bin 52 is connected to the top of the material loading rack 51. A pair of rotating blocks 53 rotatably connected to the top of the material loading bin 52 are fixedly connected to the top of the material loading bin 52. Multiple discharge holes 54 are provided inside the material loading bin 52. Multiple discharge bins 55 corresponding to the discharge holes 54 are connected to the bottom of the material loading bin 52. A filling valve for opening and closing the tea filling is provided at the bottom of the discharge bin 55. The discharge bin 55 is fixedly connected to the discharge holes 54. A pair of U-shaped support rods 6 corresponding to the connecting frame 5 are fixedly connected to the upper surface of the second support 3. One of the U-shaped support rods 6 has a position electrically connected to the conveying mechanism on the second support 3. The sensor 64 and the U-shaped support rod 6 are fixedly connected to multiple support blocks 61 corresponding to the feeding bin 55. One end of the support block 61 is provided with a guide bin 62 for filling tea into the tea canister. The upper surface of the other end of the support block 61 is provided with a vibration motor 63 for completely vibrating the tea in the guide bin 62 into the tea canister. A cylinder support block 56 is fixedly connected to the loading rack 51. The lower surface of the loading bin 52 is fixedly connected with a push-pull block 59 corresponding to the third cylinder 57. The upper surface of the cylinder support block 56 is provided with a third cylinder 57 for pushing and pulling the loading bin 52 to rotate around the rotating block 53. The piston rod of the third cylinder 57 is fixedly connected to one end of a connecting rope 58. The other end of the connecting rope 58 is fixedly connected to the outer wall of the push-pull block 59.

[0040] The vibratory motor 63 is a commonly used motor device that generates vibration or vibratory force during operation. It is used in equipment such as vibrating tables, vibrators, and vibratory feeders to achieve directional conveying and metering of materials.

[0041] A position sensor 64 is a device used to detect and measure the position or displacement of an object. They are widely used in various automation systems, mechanical equipment, industrial production lines, and consumer electronics products.

[0042] Cylinder 106, cylinder 46, and cylinder 57 are cylinders, and a primary function of cylinders is to generate force by compressing air or gas, thereby pushing or pulling objects. Furthermore, cylinders are characterized by rapid response, capable of quickly pushing and outputting force in a short time. This makes them ideal for handling defective products that require rapid removal. Compared to some other mechanical devices, cylinders have higher working efficiency and can complete tasks more effectively.

[0043] like Figure 1 , Figure 3 and Figure 4 As shown, the other end of the second support 3 is provided with a second weighing platform 4 for weighing the filled tea leaves. The outer wall of the second weighing platform 4 is fixedly connected to a second support base 42. The upper surface of the second support base 42 is fixedly connected to a second clamping arm 43 for clamping the canned tea leaves on the template base 31 onto the second weighing platform 4 for weighing. The clamping end of the second clamping arm 43 is provided with a plurality of second clamping sleeves 44 corresponding to the template base 31. The second weighing platform 4 is provided with a pushing mechanism for pushing out the unqualified tea leaves from the second weighing platform 4.

[0044] The first gripping arm 22 and the second gripping arm 43 are gripping arms. They are robotic arms used to grip, transport, and place objects on automated production lines. They typically consist of a mechanical structure, electric actuators, sensors, and a control system. The main function of the gripping arm is to accurately grip objects on the production line and perform specific operations according to preset programs and signals. It can be used in various industrial production scenarios, such as assembly lines, packaging lines, and manufacturing processes.

[0045] like Figure 5 As shown, the pushing mechanism includes multiple bases 45 connected to the second weighing platform 4, corresponding to the second clamping sleeve block 44. The upper surface of the base 45 is fixedly connected to the second cylinder 46. The piston rod of the second cylinder 46 is fixedly connected to the telescopic plate 47 for pushing the tea leaves directly below the corresponding second clamping sleeve block 44. One end of the second weighing platform 4 is provided with a second canning box 41 for receiving unqualified tea leaves.

[0046] Working principle: When a step-by-step tea filling system is required, such as... Figure 1As shown, empty tea cans are conveyed via conveyor belt 101. When an empty tea can on conveyor belt 101 passes support frame 102, photoelectric sensor 104 scans the tea can and activates. After activation, photoelectric sensor 104 sends a signal to camera 103. Camera 103 activates and illuminates and scans the empty tea can with lighting 110, then checks the display screen for impurities inside the can. When impurities are found inside the can, first cylinder 106 is activated. The piston rod of first cylinder 106 drives push plate 107 to push the empty can with impurities on conveyor belt 101 towards sliding can groove 111. The empty tea can with impurities then slides into first canning box 108. Subsequently, the empty tea cans in first canning box 108 can be processed uniformly. Empty tea cans without impurities are conveyed to one end of first support frame 1 via conveyor belt 101.

[0047] When a qualified empty tea canister is delivered to one end of the first support 1, such as Figure 2 As shown, the first clamping arm 22 can be activated. The first clamping sleeve 23 at one end of the first clamping arm 22 will pick up the qualified empty tea cans on the conveyor belt 101 and place them on the second support 3, and place them in the corresponding template seat 31 on the second support 3. When the empty tea cans placed in the template seat 31 pass through the disinfection rack 32, the ultraviolet lamp 33 will disinfect the inside of the empty tea cans. After disinfection, the empty tea cans will be conveyed to the filling mechanism.

[0048] When the empty tea canister is conveyed directly below the filling mechanism, the position sensor 64 detects the tea canister and sends a command to the conveyor mechanism to stop its operation. Figure 5 As shown, when the third cylinder 57 is activated, its piston rod pushes the push-pull block 59 to move. The push-pull block 59 causes the filling bin 52 to rotate around the rotating block 53, aligning the bottom of the discharge bin 55 with the guide bin 62 directly below. Then, the filling valve can be opened, allowing the tea leaves in the discharge bin 55 to slide into the guide bin 62. The tea leaves then slide through the bottom of the guide bin 62 into the empty tea canister. While filling the tea canister, the vibration motor 63 can be activated simultaneously. The vibration motor 63 will cause the guide bin 62 to vibrate, causing all the tea leaves in the guide bin 62 to slide into the tea canister. This process is simple and convenient.

[0049] The third cylinder 57 can be started simultaneously with the vibration of the vibration motor 63, such as... Figure 5 As shown, the piston rod of the third cylinder 57 drives one end of the connecting rope 58, and the other end of the connecting rope 58 pulls the loading bin 52 to rotate, causing the bottom discharge port of the discharge bin 55 to swing to two positions. The loading bin 52 drives the discharge bin 55 to switch the bottom discharge port of the discharge bin 55 to another set of tea canisters for filling, with the rotating block 53 as the center, making reasonable use of time and reducing waiting time.

[0050] Once the tea leaves are filled, they will be conveyed to one end of the second support 3 via a conveying mechanism. Figure 3 As shown, the tea leaves filled on the template seat 31 are clamped onto the second weighing platform 4 by the second clamping arm 43 for weighing. When the net weight of the tea leaves plus the weight of the empty tea can does not meet the requirements, the corresponding second cylinder 46 on the second weighing platform 4 will be activated. The piston rod of the second cylinder 46 drives the telescopic plate 47 to push the corresponding unqualified tea can into the second canning box 41. Finally, the unqualified tea leaves and tea cans in the second canning box 41 can be processed together, while the qualified tea leaves will be transported to the next process.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
