Description

Technical Field

[0001] The present invention relates to the technical field of visual grain counting machines, in particular to a combined double-channel belt visual grain counting machine. Background Art

[0002] With the rapid development of industrial automation technology, production lines are demanding increasingly higher precision in material counting, sorting, and quality inspection. Traditional material counting methods, such as manual counting, mechanical counters, and automatic visual counting, are no match for traditional methods. Visual counters utilize high-precision cameras and image processing technology to capture material images in real time and accurately count and classify materials using image analysis algorithms.

[0003] At present, the visual pellet counting machine needs to be used in conjunction with a vibrating machine. The traditional vibrating machine cannot effectively convey large-particle and heavy-weight materials. Too much weight is likely to weaken the amplitude, which can easily lead to material accumulation and affect the efficiency of the subsequent visual pellet counting machine. In the utility model patent (publication number: CN222281255U), an automatic counting device is disclosed, including a frame body, a storage bin, a primary vibration, a secondary vibration, a high-speed conveyor line, a high-speed camera device, and a human-machine interface; the frame body is the installation carrier of all components; the storage bin includes a main material bin for maintenance, an auxiliary material bin, and an adjustment baffle; the primary vibration and the secondary vibration are used to increase the distance between the plugs; and the high-speed conveyor line is used to increase the distance between the plugs, so that the visual reading error of the high-speed camera device is reduced, forming an automatic visual counting structure for plugs based on vibration pull distance. This patent uses primary vibration and secondary vibration in conjunction with a high-speed conveyor line to achieve high-speed counting, which is only suitable for conveying lighter materials. When the material weight is heavy, the primary vibration is responsible for initial conveying and vibration, and the secondary vibration is required for further processing. This will cause the vibration system to be overloaded, reduce the overall efficiency of the system, and have low material conveying efficiency, and even cause unnecessary mechanical damage.

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Example 1, as Figures 1-9 As shown, a combined dual-channel belt visual grain counting machine includes a frame 1. The top of the frame 1 is equipped with a hopper 2, a primary conveyor line 3, a secondary vibrating line 4, a tertiary conveyor line 5 and a lower hopper 6 from left to right. The primary conveyor line 3 is located below the hopper 2. The primary conveyor line 3, the secondary vibrating line 4 and the tertiary conveyor line 5 are designed in a stepped manner, with the primary conveyor line 3 at the highest position. The secondary vibrating line 4 is composed of two sets of fast-feeding conveyor vibrators 41 and one set of fine-feeding conveyor vibrators 42, and the fine-feeding conveyor vibrators 42 are higher than the fast-feeding conveyor vibrators 41.

[0032] The interior of the unloading bin 6 is provided with a unloading quick feeding channel 61 and a unloading fine feeding channel 62, the interior of the unloading quick feeding channel 61 is provided with a valve plate 64, and a linear array camera 7 is fixedly installed inside the frame 1, and the lens of the linear array camera 7 is facing between the third-level conveying line 5 and the unloading bin 6, and a combing assembly 9 is provided on the top of the two groups of quick feeding conveying vibrators 41.

[0033] Furthermore, both the primary conveyor line 3 and the tertiary conveyor line 5 are belt conveyor lines.

[0034] The material falls from the silo 2 onto the primary conveyor line 3. The primary conveyor line 3 adopts a belt feeding structure, which can efficiently and stably deliver the material from the silo 2, overcoming the problem that the traditional vibrator cannot effectively transport large-particle and heavy-weight materials. The traditional silo uses a vibrator to feed the material, and the amplitude is easily weakened due to too much weight. It enters the secondary vibration line 4 to play a key role. The fast-feeding vibrator 41 in the secondary vibration line 4 is running. It should be noted that at this time, the fine-feeding vibrator 42 is not running, and some materials will be transported to the fine-feeding vibrator 42. The fine-feeding vibrator 42 is higher than the fast-feeding vibrator 41, which can limit the material on the fine-feeding vibrator 42 Only a small amount of material stays on the fine feeding conveyor vibrator 42, and most of it will fall onto the fast feeding conveyor vibrator 41. The fast feeding conveyor vibrator 41 will vibrate and disperse the material transported from the first level, and then cooperate with the use of the combing component 9 to disperse the material without stacking; while the tertiary conveyor line 5 runs stably and at high speed, further widening the material spacing, creating favorable conditions for the subsequent visual recognition link, and improving the accuracy and efficiency of visual recognition. Then the material falls into the unloading fast feeding channel 61 through the tertiary conveyor line 5. During the falling process, the linear array camera 7 counts the particles, and then the material falls into the packaging bag through the unloading fast feeding channel 61.

[0035] When the target number of grains is approached, the valve plate 64 is closed, and the fine feeding and conveying vibrator 42 works to fine feed the material until the target number of grains is reached. During the fine feeding, the fast feeding and conveying vibrator 41 is still running, and the counting work is still continued in the unloading and fast feeding channel 61. The counted materials are buffered in the unloading and fast feeding channel 61 for use in the next packaging, thereby improving the counting efficiency.

[0036] The counting machine of the present invention has high overall processing efficiency, can prevent material blockage while conveying materials at high speed, and thus solves the application of counting packaging for dried tofu packaging, chocolate, candy, hardware and the like.

[0037] Embodiment 2, based on the above embodiment, further includes that a partition 51 is provided on the three-level conveyor line body 5, and the partition 51 is located between the fast conveyor vibrator 41 and the fine conveyor vibrator 42. Through the setting of the partition 51, the fine-feeding material can be limited, and the fine-feeding is more stable.

[0038] Example 3, based on the above example, further includes a backlight 8 fixedly mounted on the top of the lower hopper 6. Backlight 8 helps the vision system quickly capture clear images, especially when counting objects at high speeds. By providing uniform illumination, the vision system can process image data more quickly, thereby improving the overall operating efficiency of the machine.

[0039] Embodiment 4, based on the above embodiment, further includes that a lower hopper 63 is provided at the bottom of the lower hopper 6 , the lower hopper 63 is conical in design, and the lower hopper 63 is located below the valve plate 64 .

[0040] Furthermore, a telescopic cylinder 66 is hinged on the front of the unloading bin 6, and a valve plate 64 is rotatably installed in the unloading quick-adding channel 61. A drive rod 65 is fixedly installed on the front of the rotation center of the valve plate 64, and the drive rod 65 is hinged to the telescopic end of the telescopic cylinder 66.

[0041] By controlling the operation of the telescopic cylinder 1 66, the telescopic cylinder 1 66 drives the valve plate 64 to rotate through the driving rod 65, and the control is simple.

[0042] Embodiment 5, on the basis of the above embodiment, further includes that the combing assembly 9 includes a combing cover 91 mounted on the top of two groups of fast-feeding conveyor vibrators 41, and multiple groups of combing plates 92 are rotatably installed inside the combing cover 91. In this embodiment, five groups are set, and the specific number can be adjusted according to the type of material. The rotation center of the combing plate 92 is away from the primary conveyor line body 3, and a buffering distance is set between the combing plate 92 and the primary conveyor line body 3. A vibration distance is set between the bottom of the combing plate 92 and the top of the fast-feeding conveyor vibrator 41. The vibration distance will not affect the vibration of the fast-feeding conveyor vibrator 41. The combing plate 92 can swing back and forth, and multiple groups of telescopic dials 96 are linearly arrayed on both sides of the combing plate 92. The telescopic dial 96 can be telescopic, and the cross-section of the telescopic dial 96 after being extended is arc-shaped.

[0043] Furthermore, the combing plate 92 is designed to be triangular at one end close to the primary conveyor line body 3 to prevent the combing plate 92 from blocking the material, thereby achieving a better combing effect.

[0044] The first-level conveyor line 3 first conveys the material to the fast-feeding vibrator 41 at the slow material spacing. The fast-feeding vibrator 41 performs preliminary vibration on the material, and then the vibrated material enters between the combing plates 92. As the combing plates 92 swing back and forth, the combing plates 92 will give the material a thrust that is an inclined force, which will not only push the material in the swinging direction, but may also push the material in the direction of the first-level conveyor line 3 or the third-level conveyor line 5. When the combing plate 92 swings, the telescopic dial 96 on one side of the swinging direction will extend, which will allow the material to slide along the combing plate 92 toward the first-level conveyor line 3. Restriction, so that the material can be stably pushed toward the direction of the three-stage conveyor line body 5, thereby accelerating the dispersion of the material, so that the material can fall onto the three-stage conveyor line body 5 faster, and will not accumulate on the fast-adding conveyor vibrator 41. It is more suitable for materials with heavier weights, and can achieve high-speed conveying and material distribution, and high grain counting efficiency. It should be noted that the cross-street surface of the telescopic pusher 96 is arc-shaped, that is, concave design, which provides the necessary rigidity and resists deformation, just like the angle steel reinforced structure. While it can be bent and stored, the protruding part has sufficient supporting strength and is not easily bent by the material, thereby ensuring the stability of the material pusher.

[0045] Embodiment 6, on the basis of the above embodiment, further includes: two groups of inner sliding cavities 93 are opened inside the combing plate 92, and material guide ports 931 are opened in a linear array on both sides of the combing plate 92, and the material guide ports 931 on both sides are respectively connected to the two groups of inner sliding cavities 93, and the telescopic dial 96 passes through the material guide port 931. The interior of the inner sliding cavity 93 is slidably connected with a mounting slide 94, and the telescopic dial 96 is fixedly connected to the mounting slide 94. A top spring 95 is provided between the mounting slide 94 and the inner sliding cavity 93, and a connecting top column 97 is inserted into the interior of the combing plate 92, and the mounting slide 94 is fixedly installed on the connecting top column 97. A guide top ring 98 is fixedly installed on the inner top of the combing cover 91, and the connecting top column 97 contacts the guide top ring 98, and the middle of the guide top ring 98 is recessed inward.

[0046] When the combing plate 92 swings, it drives the connecting top post 97 to swing relative to the guide top ring 98. The guide top ring 98 pushes the connecting top post 97 in the swinging direction to slide. The connecting top post 97 in the swinging direction drives the telescopic selector 96 to extend through the mounting plate 94. After extending, the telescopic selector 96 has a concave shape, providing the necessary rigidity, resisting deformation, and stably moving the material. It should be noted that the other set of connecting top posts 97 is located in a recessed position in the middle of the guide top ring 98. The telescopic selector 96 on this side does not extend and does not obstruct the material. When the combing plate 92 swings back, the top spring 95 pushes the mounting plate 94 to reset, and the telescopic selector 96 retracts. Therefore, through the arrangement of this embodiment, the telescopic selector 96 can be extended and retracted while the combing plate 92 swings. Moreover, the inclination angle of the recessed portion of the guide top ring 98 is designed to be 15 degrees, so a smaller angle can achieve rapid extension and retraction of the telescopic selector 96.

[0047] Embodiment 7, based on the above embodiment, further includes: an outer cover shell 912 is fixedly installed on the top of the comb cover 91, a telescopic cylinder 2 910 is fixedly installed inside the outer cover shell 912, a transmission gear rod 911 is fixedly installed on the telescopic end of the telescopic cylinder 2 910, and a transmission gear 99 is fixedly installed on the top of the comb plate 92, and the transmission gear 99 is meshed with the transmission gear rod 911.

[0048] By controlling the extension and retraction of the telescopic cylinder 2 910 , the telescopic cylinder 2 910 drives the transmission gear rod 911 to slide back and forth, and the transmission gear rod 911 drives the combing plate 92 to swing back and forth through the transmission gear 99 , and the control is simple.

[0049] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
