Description

TECHNICAL FIELD

[0001] The utility model relates to material conveying and sorting technical field, especially relate to a naked seed sorting device. BACKGROUND

[0002] In the production and processing process, naked seeds (such as melon seeds, peanuts, nuts and the like) usually need to be arranged in a direction, grouped quantitatively and discharged so as to be packaged, roasted or coated in subsequent processes. The common sorting device in the prior art generally comprises a vibration disc and a straight conveying track. The material is arranged in a direction by the vibration disc and then enters the conveying track, and then is collected quantitatively and discharged by a discharge mechanism at the end. However, in actual operation, the material output from the vibration disc is usually closely spaced on the conveying track, or even connected head to tail. When the material continuously and densely reaches the discharge station, the counting sensor of the discharge mechanism is likely to misjudge or miss, resulting in inaccurate quantity of each discharge and affecting the stability and consistency of subsequent processes. In addition, the feeding mechanism usually uniformly distributes the material to multiple vibration discs, which is likely to cause material shortage or accumulation in some channels due to different consumption speeds of the vibration discs, affecting the overall efficiency. When collecting the quantitative material, the discharge mechanism also usually uses a single sensor for counting, lacks a review mechanism and is likely to cause counting errors due to material adhesion or abnormal posture.

Detailed Implementation

[0021] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0022] Example: Figures 1 to 5 The bare seed feeding device shown includes a frame 1 and a controller 2. The frame 1 is provided with two sets of parallel feeding channels 3 and a feeding mechanism 4 for feeding the feeding channels 3. A vibrating plate 5 is located below the feeding mechanism 4. The feeding channels 3 include two conveyor belts 31 connected end to end. The conveyor belt 31 on the side closer to the vibrating plate 5 is called the front conveyor belt 31, and the conveyor belt 31 on the side closer to the feeding mechanism 6 is called the rear conveyor belt 31. Each conveyor belt 31 is independently equipped with a servo motor 32 for driving, and can be started, stopped and speed adjusted independently.

[0023] A first sensor 51 is provided above the outlet of the vibratory feeder 5. A second sensor 33 and a third sensor 34 are provided between the two connected conveyor belts 31 for coordinating the control of the material spacing. The second sensor 33 is located above the rear side of the output end of the front conveyor belt 31 (i.e., the connection point with the rear conveyor belt 31), and the third sensor 34 is located at the input end of the rear conveyor belt 31. A fourth sensor 35 is provided at the connection point between the conveyor belt 31 and the feeding mechanism 6. A photoelectric camera 61 (visual inspection device) is provided on the upper side of the feeding mechanism 6.

[0024] The feeding mechanism 4 includes a common feeding hopper 41, a feeding conveyor belt 43, and two feeding ports 42 respectively aligned with each vibrating plate 5. The outer walls of the two feeding ports 42 are equipped with fifth sensors 44 to detect the remaining material (e.g., material level) in their corresponding vibrating plates 53. At the intersection of the two feeding ports 42, there is a feeding baffle 45 and a feeding cylinder 46 that drives the feeding baffle 45 to rotate. In the initial state, all feeding ports 42 are open, and material is fed evenly. When a fifth sensor 44 detects that the material in its corresponding vibrating plate 5 is about to be insufficient, the controller 2 instructs the feeding cylinder 46 to operate, driving the feeding baffle 45 to rotate and temporarily closing the other feeding ports 42, so that the material on the feeding conveyor belt 43 is concentratedly supplied to the vibrating plate 5 that is short of material. After the material level is restored, the baffle is reset, and even feeding resumes.

[0025] The discharging mechanism 6 includes a discharging channel 62 obliquely arranged at the outlet end of the sorting channel 3, the middle part of the discharging channel 62 is provided with an openable and closable discharging baffle 63 and a baffle cylinder 64 for driving the discharging baffle 63 to open and close, the photoelectric camera 61 is arranged directly above the side of the discharging baffle 63 facing the sorting channel 3, the outlet end of the discharging channel 62 is provided with an extendable and retractable discharging port 66 through a mounting cylinder 65, the upper side of the discharging port 66 is provided with a poking cylinder 67, and the two sides and the bottom of the discharging channel 62 are provided with light sources 68 to improve the brightness of the inside of the discharging channel 62 and ensure the checking accuracy of the photoelectric camera 61.

[0026] The vibration disc 5, the conveying belts 31, the discharging mechanism 6, the feeding mechanism 4 and all the sensors and the photoelectric camera 61 are electrically connected with the controller 2.

[0027] The materials are sequentially sent out from the vibration disc 5, detected by the first sensor 51 and then enter the front conveying belt 31, when a material on the front conveying belt 31 reaches the end thereof, the second sensor 33 is triggered, if at this time the input end of the rear conveying belt 31 has a material (i.e. the third sensor 34 S3 is also triggered), it indicates that the interval between the front and rear materials is too small, the controller 2 immediately instructs the servo motor 32 of the front conveying belt 31 to pause, the servo motor 32 of the rear conveying belt 31 continues to work to convey the material on the rear conveying belt 31 forward, and when the signal of the third sensor 34 disappears (the material on the rear conveying belt 31 has left), the controller 2 instructs the front conveying belt 31 to resume operation, thereby creating an increased interval between the front and rear materials.

[0028] After the interval adjustment, the materials sequentially pass through the rear conveying belt 31 and are counted one by one by the fourth sensor 35, when the counting reaches a preset number (for example, 10), the controller 2 instructs the rear conveying belt 31 to pause; at this time, the photoelectric camera 61 takes a picture of the materials gathered in a specific area (the side of the discharging baffle 63 facing the sorting channel 3) of the discharging mechanism 6 to accurately check the number of materials, if the number is correct, the discharging action is performed, if the number is incorrect (e.g. overcounting or undercounting), the rear conveying belt 31 resumes operation to continue feeding or waiting until the photoelectric camera 61 confirms that the number is correct, the fourth sensor 35 is reset and counting is restarted. At the beginning of work, the discharging baffle 63 is in a closed state, when the number of materials is checked to be correct, the baffle cylinder 64 is actuated to open the discharging baffle 63, the materials slide along the inclined surface into the discharging port 66, then the poking cylinder 67 is actuated to push the materials in the discharging port 66 into the downstream collecting container or conveying belt, completing a quantitative discharging, and then each mechanism is reset for the next cycle.
