Technical Field
[0001] This utility model relates to the field of capsule sorting technology, and in particular to a weighing and sorting device for defective capsules. Background Technology
[0002] In the capsule production process, defective products separated after initial screening, such as those with abnormal weight or damaged appearance, are usually collected in one go without further subdivision. Although these defective products are all judged to be unqualified, the specific defect types are different, including insufficient filling, excessive filling, and shell damage or cracking.
[0003] In the prior art, such as the empty capsule weighing and sorting device disclosed in patent CN209935292U, the complex conveying mechanism and large equipment space are solved by using structures such as a swing arm drive motor and a weighing platform swing servo drive motor, thus achieving high weighing and sorting efficiency.
[0004] A search revealed a Chinese patent with publication number CN209935292U, which provides a device for weighing and sorting empty capsules. Through a conveying mechanism and a weighing structure, it enables the screening of empty capsules, integrates well with the production line, has high weighing and sorting efficiency, and occupies little space.
[0005] However, during use, it was found that the recycling value of different types of defective capsules varies significantly for capsules with different raw material values. Capsules with abnormal weight but intact shells can be reused by readjusting the filling amount, while capsules with broken shells can only have their internal raw materials recycled. The existing testing of defective capsules has low sorting efficiency, which easily causes raw material contamination and makes it difficult to grade them, resulting in a low overall recycling rate of defective products and increased waste of production raw materials. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a weighing and sorting device for defective capsules. Multiple industrial vision cameras inspect the appearance of rotating capsules to determine whether there are any issues such as shell damage or cracking. The turntable guides the capsules to two sorting slots or chutes on the capsule slide according to the type of defect, thereby achieving the sorting of different types of defective capsules. The sorting slots enable graded output, improving the efficiency of raw material recycling and reducing the waste of production materials.
[0007] To solve the above technical problems, this utility model provides the following technical solution: a capsule defective product weighing and sorting device, including a capsule slide, the capsule slide having an inclined structure, support columns installed at the four corners of the bottom surface of the capsule slide, a weighing platform installed at one end of the capsule slide, a visual inspection component installed in the middle of the capsule slide, and a sorting component provided at the other end of the capsule slide;
[0008] The visual inspection component includes a C-shaped frame, on the inner wall of which multiple industrial vision cameras are mounted. The bottom surface of the C-shaped frame is fixedly connected to the top surface of the capsule slide. A rotating belt is provided at the lower middle part of the capsule slide. Conveying rollers are rubbed against both ends of the inner wall of the rotating belt. The two ends of the conveying rollers are rotatably connected to the capsule slide.
[0009] The sorting assembly includes a turntable, the outer peripheral wall of which is rotatably connected to the capsule slide, and two sorting slots are provided on the top surface of the capsule slide at the end away from the weighing platform.
[0010] The top surfaces of the capsule slide, the weighing platform, and the turntable are each provided with a sliding groove.
[0011] Preferably, the support column is a lifting column, and two feeding components are respectively provided at both ends of the weighing platform. The feeding component includes a limiting sleeve, and an insert block is slidably connected to the inner wall of the limiting sleeve. The lower end of the insert block is inserted into the sliding groove.
[0012] Preferably, the bottom surfaces of the two limiting sleeves are fixedly connected to the top surface of the capsule slide, and an electric push rod is installed at one end of the limiting sleeve. The piston rod of the electric push rod is fixedly connected to the upper end of the insert block.
[0013] The above technical solution controls the orderly entry of capsules into the weighing platform by the insertion and disengagement of the insert block and the slide groove, avoiding the impact of multiple capsules stacking on the weight detection accuracy, and finally completing the weight detection of defective products through the weighing platform.
[0014] Preferably, a worm gear is sleeved on the outer peripheral wall of one end of the conveying roller, and a worm is meshed with the lower end of the worm gear. The two worms are coaxially connected. A first servo motor is installed on the side wall of the capsule slide, and the output shaft of the first servo motor is coaxially connected with one of the worms.
[0015] Preferably, one end of the worm gear has a fixed block attached to its outer peripheral wall, and the top surfaces of the two fixed blocks are respectively fixedly connected to the bottom surface of the capsule slide.
[0016] Through the above technical solution, the output shaft of the first servo motor drives the coaxially connected worm gear to rotate, and the worm gear meshes with and drives the worm wheel at one end of the conveyor roller to rotate, thereby driving the conveyor roller to rotate synchronously.
[0017] Preferably, a second servo motor is provided at the lower end of the turntable, the output shaft of the second servo motor is fixedly connected to the middle of the turntable, and the second servo motor is mounted on the bottom surface of the capsule slide via a mounting bracket.
[0018] Preferably, a U-shaped frame is fixed on the turntable, and two limiting grooves are opened on the U-shaped frame. A slider is slidably connected inside the limiting groove, and a stop is fixed between the two sliders. The lower end of the stop is inserted into the edge of the turntable.

[0020] The above technical solution drives the turntable to rotate around its own axis through the output shaft of the second servo motor, while the output shaft of the third servo motor drives the rocker arm to rotate. The rocker arm pulls the upper end of the stop block through the connecting rod, so that the sliders at both ends of the stop block slide along the limiting groove of the U-shaped frame, thereby controlling the insertion depth between the lower end of the stop block and the edge of the turntable.
[0021] The beneficial effects of this invention are as follows: After weight detection, the capsules continue to be conveyed along the chute to the vision inspection component in the middle of the capsule slide. At this time, the conveyor roller rotates, driving the rotating belt that is in frictional contact with it to rotate. The rotating belt further drives the capsules to rotate synchronously. At the same time, multiple industrial vision cameras on the inner wall of the C-shaped frame perform appearance inspection on the rotating capsules to determine whether there are any shell damage or cracks. The rotation of the capsules by the rotating belt, combined with multiple industrial vision cameras, improves the appearance inspection effect and efficiency. After completing the weight and appearance inspection, the capsules continue to slide along the chute to the sorting component at the other end of the capsule slide and enter the chute on the top surface of the turntable. The turntable rotates around its own axis and guides the capsules to the two sorting slots or chutes opened on the capsule slide according to the defect type, realizing the sorting of different types of defective capsules.

[0031] like Figure 1-7 As shown, this embodiment provides a capsule defective product weighing and sorting device, including a capsule slide 100, which has an inclined structure. Support columns 101 are installed at the four corners of the bottom surface of the capsule slide 100. A weighing platform 103 is installed at one end of the capsule slide 100. A vision inspection component 200 is installed in the middle of the capsule slide 100. A sorting component 300 is provided at the other end of the capsule slide 100.
[0032] The vision inspection assembly 200 includes a C-shaped frame 201, on the inner wall of which multiple industrial vision cameras 202 are mounted. The bottom surface of the C-shaped frame 201 is fixedly connected to the top surface of the capsule slide 100. A rotating belt 203 is provided at the lower middle part of the capsule slide 100.

[0033] The sorting component 300 includes a turntable 301, the outer peripheral wall of which is rotatably connected to the capsule slide 100, and two sorting slots 302 are provided on the top surface of the capsule slide 100 away from the weighing platform 103.
[0034] The top surfaces of the capsule slide table 100, the weighing platform 103, and the turntable 301 are respectively provided with slide grooves 102.
[0035] The support column 101 is a lifting column. Two feeding components 400 are respectively provided at both ends of the weighing platform 103. The feeding component 400 includes a limiting sleeve 401. An insert block 402 is slidably connected to the inner wall of the limiting sleeve 401. The lower end of the insert block 402 is inserted into the slide groove 102. The bottom surfaces of the two limiting sleeves 401 are fixedly connected to the top surface of the capsule slide table 100. An electric push rod 403 is installed at one end of the limiting sleeve 401. The piston rod of the electric push rod 403 is fixedly connected to the upper end of the insert block 402. By inserting and disengaging the insert block 402 from the slide groove 102, the capsules are controlled to enter the weighing platform 103 in an orderly manner, avoiding the stacking of multiple capsules from affecting the weight detection accuracy. Finally, the weight detection of defective products is completed by the weighing platform 103.
[0036] A worm gear 205 is sleeved on the outer peripheral wall of one end of the conveying roller 204. A worm 206 is meshed with the lower end of the worm gear 205. The two worms 206 are coaxially connected. A first servo motor 207 is installed on the side wall of the capsule slide 100. The output shaft of the first servo motor 207 is coaxially connected with one of the worms 206. A fixed block 208 is connected to the outer peripheral wall of one end of the worm 206. The top surfaces of the two fixed blocks 208 are fixedly connected to the bottom surface of the capsule slide 100. The output shaft of the first servo motor 207 drives the coaxially connected worm 206 to rotate. The worm 206 meshes with and drives the worm gear 205 at one end of the conveying roller 204 to rotate, thereby driving the conveying roller 204 to rotate synchronously.
[0037] A second servo motor 306 is provided at the lower end of the turntable 301. The output shaft of the second servo motor 306 is fixedly connected to the middle of the turntable 301. The second servo motor 306 is mounted on the bottom surface of the capsule slide table 100 via a mounting bracket 307. A U-shaped frame 303 is fixedly provided on the turntable 301. Two limiting grooves 304 are provided on the U-shaped frame 303. A slider 305 is slidably connected inside the limiting grooves 304. A stop block 308 is fixedly provided between the two sliders 305. The lower end of the stop block 308 is inserted into the edge of the turntable 301. A connecting rod 309 is rotatably connected to the upper end of the stop block 308. A third servo motor 310 is mounted on the top surface. A rocker arm 311 is sleeved on the output shaft of the third servo motor 310. The other end of the rocker arm 311 is rotatably connected to the connecting rod 309. The output shaft of the second servo motor 306 drives the turntable 301 to rotate around its own axis. At the same time, the output shaft of the third servo motor 310 drives the rocker arm 311 to rotate. The rocker arm 311 pulls the upper end of the stop block 308 through the connecting rod 309, so that the sliders 305 at both ends of the stop block 308 slide along the limiting groove 304 of the U-shaped frame 303, thereby controlling the insertion depth between the lower end of the stop block 308 and the edge of the turntable 301.
[0038] Working principle: The defective capsules to be sorted first enter the chute 102 of the capsule slide 100. Because the capsule slide 100 has an inclined structure, the capsules slide along the chute 102 with the help of gravity. They are first transported to the weighing platform 103 at one end of the capsule slide 100. The weight of the defective products is detected by the weighing platform 103 to determine whether there is an abnormal weight problem of insufficient or excessive filling.
[0039] After weight detection, the capsule continues to be conveyed along the chute 102 to the vision inspection component 200 in the middle of the capsule slide 100. At this time, the conveyor roller 204 rotates, driving the rotating belt 203 that is in frictional contact with it to rotate. The rotating belt 203 further drives the capsule to rotate synchronously. At the same time, multiple industrial vision cameras 202 on the inner wall of the C-shaped frame 201 perform appearance inspection on the rotating capsule to determine whether there is any shell damage or cracking. The rotating belt 203 drives the capsule to rotate in conjunction with multiple industrial vision cameras 202, which improves the appearance inspection effect and efficiency.
[0040] After the capsules have completed weight and appearance inspections, they continue to slide along the chute 102 to the sorting assembly 300 at the other end of the capsule slide table 100, and enter the chute 102 on the top surface of the turntable 301. The turntable 301 rotates around its own axis, and according to the type of defect of the capsules, guides them to the two sorting slots 302 or chute 102 opened on the capsule slide table 100, realizing the sorting of different types of defective capsules. The sorting slots 302 realize graded output, improve the efficiency of raw material recycling, and reduce the waste of production materials.
[0041] Before the defective capsules to be sorted enter, the tilt angle of the capsule slide 100 is adjusted by adjusting the support column 101 on the bottom surface of the capsule slide 100 to adapt to the gravity conveying requirements of capsules of different specifications and ensure stable conveying. After the adjustment is completed, the defective capsules to be sorted enter the slide groove 102 of the capsule slide 100 and slide along the slide groove 102 with the help of the gravity of the tilted structure. At this time, the feeding components 400 at both ends of the weighing platform 103 are activated, and the electric push rod 403 at one end of the limiting sleeve 401 pushes the insert 402 to slide along the inner wall of the limiting sleeve 401. Through the insertion and disengagement of the insert 402 with the slide groove 102, the capsules are controlled to enter the weighing platform 103 in an orderly manner to avoid the stacking of multiple capsules from affecting the weight detection accuracy. Finally, the weight detection of defective products is completed by the weighing platform 103, providing accurate data support for subsequent grading and sorting.
[0042] After weight detection, the capsule continues to be conveyed along the chute 102 to the vision inspection assembly 200. At this time, the output shaft of the first servo motor 207 on the side wall of the capsule slide 100 drives the coaxially connected worm gear 206 to rotate. The worm gear 206 meshes with and drives the worm wheel 205 at one end of the conveyor roller 204 to rotate, thereby driving the conveyor roller 204 to rotate synchronously. The conveyor roller 204 drives the rotating belt 203 to rotate through friction. The rotating belt 203 further drives the capsule to rotate around its own axis. At the same time, multiple industrial vision cameras 202 on the inner wall of the C-shaped frame 201 perform appearance inspection on the rotating capsule. The transmission structure of the worm wheel 205 and worm gear 206 ensures that the rotating belt 203 rotates at a uniform speed, improving the consistency and accuracy of appearance inspection.
[0043] After weight and appearance inspection, the capsules slide along the chute 102 to the sorting assembly 300 and enter the chute 102 on the top surface of the turntable 301. The output shaft of the second servo motor 306 drives the turntable 301 to rotate around its own axis, while the output shaft of the third servo motor 310 drives the rocker arm 311 to rotate. The rocker arm 311 pulls the upper end of the stop block 308 through the connecting rod 309, so that the sliders 305 at both ends of the stop block 308 slide along the limiting groove 304 of the U-shaped frame 303, thereby controlling the insertion depth between the lower end of the stop block 308 and the edge of the turntable 301. According to the defect type of the capsule, the rotation angle of the turntable 301 and the position of the stop block 308 are coordinated to guide the capsules to the two sorting slots 302 or the chute 102 of the capsule slide table 100, so as to achieve accurate sorting of different types of defective products and reduce capsule deviation or mixing during the sorting process.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
