Description

Technical Field

[0001] The present invention relates to the technical field of down sorting, and in particular to a large-clump down automatic sorting device and method based on machine vision. Background Art

[0002] Down is a filling material widely used in clothing and bedding. It is mainly composed of feathers and down from waterfowl such as ducks and geese. These feathers undergo a series of treatments and processing, such as cleaning, screening, and impurity removal, to finally obtain down suitable for filling material. The sorting of down raw materials is a very important step in the down processing process, which directly affects the quality and use of down. Down raw material sorting equipment is a special machine used to separate and sort mixed down raw materials. The working principle of this type of equipment is mainly based on the physical properties of down raw materials, such as density, shape, color, etc., and the sorting is achieved through specific mechanical or airflow operations.

[0003] When sorting most down, a stirring rod is usually required to perform preliminary stirring and separation of large down clumps. However, the stirring rod can only perform preliminary separation of large down clumps and is difficult to perform more detailed separation, resulting in dust mixed in some clumps of down that is difficult to effectively separate. Therefore, we proposed an automatic large down sorting device and method based on machine vision. Summary of the Invention

[0005] The stirring separation device includes a linkage long rod, a first connecting rod fixedly connected to the outer side of the linkage long rod, a slender rod fixedly connected to the outer side of the slender rod, and small spikes fixedly connected to the outer side of the slender rod. By arranging a plurality of small spikes on the outer side of the slender rod, the down is subjected to tearing and fine separation, thereby preventing the down separated by secondary stirring from still being partially clumped, resulting in dust inclusion and difficulty in effective separation.

[0006] One end of the stirring separation device away from the driving motor is rotatably connected to the inner wall of the top-opening square shell via a rotating bolt, and one side of the vertical electric slide is fixedly connected to one side of the top-opening square shell;

[0007] One end of the linkage long rod is fixedly connected to the driving shaft of the driving motor, and one end of the linkage long rod is rotatably connected to the inner wall of the top-open square shell through a rotating bolt;

[0008] There are multiple first connecting rods, and the multiple first connecting rods are distributed outside the linkage long rod; there are multiple small thorn blocks, and the multiple small thorn blocks are distributed outside the slender rod;

[0009] The outer side of the slender rod is fixedly connected to a second connecting rod, and one end of the second connecting rod away from the slender rod is fixedly connected to a long scraping rod. By arranging a slender rod and a long scraping rod at one end of the first connecting rod and the second connecting rod respectively, the large down clumps are fully stirred and separated for a second time, thereby preventing the intermittently arranged first connecting rod and second connecting rod from failing to fully stir and separate all the large down clumps and affecting the subsequent sorting effect. As the linked long rod rotates, the long scraping rod scrapes and cleans the inner wall of the curved material plate, thereby preventing excessive dust particles attached to the inner wall of the curved material plate from floating in the top open square shell and being sucked away as the down is stirred. When the long scraping rod scrapes the inner wall of the curved material plate, the down accumulated on the inner wall of the curved material plate is lifted up together, thereby preventing large down clumps in part of the inner wall of the curved material plate from always being deposited in the same position and being difficult to be stirred and separated. A plurality of second connecting rods are provided, and the plurality of second connecting rods are distributed between the slender rod and the long scraping rod.

[0010] Furthermore, the suction-type sorting device includes a square empty shell, both sides of the square empty shell are fixedly connected with side connecting blocks, the inner wall of the square empty shell is fixedly connected with a built-in square plate, the bottom of the built-in square plate is provided with a first circular hole, and the top of the built-in square plate is fixedly connected with a concave limiting long rod, and the top sliding square plate is limited by arranging a concave limiting long rod on the top sliding square plate to prevent the top sliding square plate from sliding excessively, resulting in some first circular holes failing to align with the second circular holes and affecting use.

The down is sucked in batches, which prevents the need to connect the top-open square shell with different types of sorting devices in sequence when sorting down of different sizes, which is more cumbersome. A dust filter circular hole is provided on the top of the top sliding square plate. By opening multiple dust filter circular holes on the top sliding square plate, the dust in the down is sucked and separated, which prevents the subsequently sorted down from being mixed with too many dust particles and affecting the subsequent use of the down. The top of the square empty shell is connected to the bottom of the arc-shaped ventilation pipe, and the bottom of the square empty shell is fixedly connected to the top of the cleaning device. The outer side of the side connecting block is slidably connected to the inner side of the vertical electric slide rail. Two concave limiting long rods are provided, and the two concave limiting long rods are distributed on both sides of the square connecting plate. The bottom of the square connecting plate is slidably connected to the top of the built-in square plate, and the bottom of the top sliding square plate is slidably connected to the top of the built-in square plate.

[0011] Furthermore, the cleaning device includes a fixed side plate, one side of the fixed side plate is fixedly connected to a straight electric slide rail, the inner side of the straight electric slide rail is slidably connected to an inner sliding round rod, the outer side of the inner sliding round rod is fixedly connected to a hard brush, and the hard brush moving with the inner sliding round rod performs a stripping cleaning process on the inside of the first circular hole and the bottom surface of the built-in square plate to prevent part of the down from adhering to the bottom surface of the built-in square plate or accumulating inside the first circular hole to cause blockage and affect the subsequent sorting effect, and one side of the straight electric slide rail is fixedly connected to a square cover, and the hard brush is covered and protected by arranging the square cover near the two sides of the bottom of the built-in square plate. , to prevent some of the down sucked in from still adhering to the hard brush when the hard brush is not in use, which increases the cleaning steps, one side of the straight electric slide rail is fixedly connected with an arc-shaped barbed plate, and the arc-shaped barbed plate performs a piercing and stripping treatment on the moving hard brush, to prevent too much down from being mixed between the brushes after the hard brush is used for a long time, which is difficult to handle and affects the subsequent cleaning effect of the hard brush, the top of the fixed side plate is fixedly connected to the bottom of the square empty shell, the top of the straight electric slide rail is fixedly connected to the bottom of the square empty shell, one side of the square baffle is fixedly connected to one side of the fixed side plate, and one side of the arc-shaped barbed plate is fixedly connected to one side of the square baffle.

[0012] A method for automatically sorting large down feathers based on machine vision includes the following steps:

[0013] S1: Place down, place large down in the curved material plate and push it into the top-open square shell for sorting;

[0017] S5: Cleaning the residual materials. When the suction sorting device sucks in the down, the cleaning device can be used to scrape and clean the down that is blocked at the bottom.

[0018] The present invention provides a large-scale down automatic sorting device and method based on machine vision. It has the following beneficial effects:

[0019] 1. This large-clump down automatic sorting equipment and method based on machine vision uses multiple small thorns on the outside of a slender rod to tear and crush the down, preventing the down separated by secondary stirring from still being partially clumped, which may cause dust to be mixed in and difficult to effectively separate. By gradually connecting and aligning the first circular hole with the second circular hole, down of different sizes is sucked in batches, avoiding the need to sequentially connect the top-open square shell with different types of sorting devices when sorting down of different sizes, which is more cumbersome. The hard brush that moves with the inner sliding circular rod performs a stripping cleaning process on the inside of the first circular hole and the bottom surface of the built-in square plate, preventing some down from adhering to the bottom surface of the built-in square plate or accumulating inside the first circular hole, causing blockage and affecting the subsequent sorting effect.

[0020] 2. The large-clump down automatic sorting equipment and method based on machine vision are provided with a stirring separation device, which performs a secondary stirring and separation on the large-clump down by arranging a slender rod and a long scraping rod at one end of the first connecting rod and the second connecting rod respectively, so as to prevent the intermittently arranged first connecting rod and the second connecting rod from failing to fully stir and separate all the large-clump down and affecting the subsequent sorting effect; the down is torn and crushed by arranging a plurality of small thorn blocks on the outer side of the slender rod, so as to prevent the down separated by the secondary stirring from still being locally clumped, resulting in dust being mixed in and difficult to be effectively separated; the long scraping rod rotates with the linked long rod to scrape and clean the inner wall of the arc-shaped material plate, so as to prevent excessive dust particles attached to the inner wall of the arc-shaped material plate from being difficult to float in the top-open square shell with the stirring of the down and being sucked away; the long scraping rod lifts up the down accumulated on the inner wall of the arc-shaped material plate when scraping the inner wall of the arc-shaped material plate, so as to prevent the large down in some areas of the inner wall of the arc-shaped material plate from always being deposited in the same position and being difficult to be stirred and separated.

[0021] 3. The large-scale down automatic sorting equipment and method based on machine vision are provided with a suction-type sorting device. A plurality of dust filter circular holes are provided on the top sliding square plate to separate the dust in the down by suction, thereby preventing the subsequent sorted down from being mixed with too many dust particles and affecting the subsequent use of the down. Down of different sizes are sucked in batches by gradually connecting and aligning the first circular hole with the second circular hole, thereby preventing the need to sequentially connect the top-opened square shell with different types of sorting devices when sorting down of different sizes, which is more cumbersome. A concave limiting long rod is provided on the top sliding square plate to limit the sliding of the top sliding square plate, thereby preventing the top sliding square plate from sliding excessively, resulting in some first circular holes failing to align with the second circular holes and affecting use.

[0022] 4. The large-clump down automatic sorting equipment and method based on machine vision is provided with a cleaning device. The hard brush moving with the inner sliding round rod performs a stripping cleaning process on the inside of the first circular hole and the bottom surface of the built-in square plate to prevent a part of the down from adhering to the bottom surface of the built-in square plate or accumulating inside the first circular hole to cause blockage and affect the subsequent sorting effect. The arc-shaped thorn plate performs a piercing stripping process on the moving hard brush to prevent excessive down from being mixed between the brushes after long-term use, which is difficult to handle and affects the subsequent cleaning effect of the hard brush. The hard brush is covered and protected by arranging a square cover near both sides of the bottom of the built-in square plate to prevent some of the down that is sucked in from still adhering to the hard brush when the hard brush is not in use, which increases the cleaning step.

[0037] One end of the linkage long rod 401 is fixedly connected to the driving shaft of the driving motor 3, and one end of the linkage long rod 401 is rotatably connected to the inner wall of the top-open square shell 1 through a rotating bolt;

[0038] There are multiple first connecting rods 402, and the multiple first connecting rods 402 are distributed outside the linkage long rod 401. There are multiple small thorn blocks 404, and the multiple small thorn blocks 404 are distributed outside the slender rod 403.

[0039] The outer side of the slender rod 403 is fixedly connected with a second connecting rod 405, and the end of the second connecting rod 405 away from the slender rod 403 is fixedly connected with a long scraping rod 406. There are multiple second connecting rods 405, and multiple second connecting rods 405 are distributed between the slender rod 403 and the long scraping rod 406. When in use, a large down is placed in the arc-shaped material plate 2 and pushed into the top-open square shell 1. The vertical electric slide 7 drives the suction sorting device 8 to move down and drives the cleaning device 9 at the bottom to move down together until it contacts the top of the top-open square shell 1 to form a closed space, and then starts the drive motor 3 to The stirring separation device 4 is used to stir the large down in the curved material plate 2 so that the large down is separated. After stirring the large down for a period of time, the fan 11 is used to make the suction sorting device 8 suck the dust and down of different sizes in the large down in batches and discharge them from the docking pipe 12. At the same time, when the large down is being sorted, the intelligent visual camera 5 can be used to observe the sorted down in the top-open square shell 1.

[0042] The cleaning device 9 includes a fixed side plate 901, one side of the fixed side plate 901 is fixedly connected to a straight electric slide rail 902, the inner side of the straight electric slide rail 902 is slidably connected to an inner sliding round rod 903, the outer side of the inner sliding round rod 903 is fixedly connected to a hard brush 904, one side of the straight electric slide rail 902 is fixedly connected to a square stop cover 905, one side of the straight electric slide rail 902 is fixedly connected to an arc-shaped thorn plate 906, the top of the fixed side plate 901 is fixedly connected to the bottom of the square empty shell 801, the top of the straight electric slide rail 902 is fixedly connected to the bottom of the square empty shell 801, one side of the square stop cover 905 is fixedly connected to one side of the fixed side plate 901, and one side of the arc-shaped thorn plate 906 is fixedly connected to one side of the square stop plate. When in use, The vertical electric slide rail 7 drives the suction sorting device 8 to drive the cleaning device 9 to move down to contact the top of the top-open square shell 1 to form a closed space with the top-open square shell 1, and then the fan 11 is used to evacuate the square empty shell 801, so that the square empty shell 801 can suck the dust and down in the top-open square shell 1 through the first circular hole 804. When the down in the top-open square shell 1 is sorted and sucked, the threaded torsion rod 806 is twisted to make the threaded torsion rod 806 move in the square empty shell 801 to push the square connecting plate 807 to move. The movement of the square connecting plate 807 drives the top sliding square plate 808 on one side to move until the top sliding square plate 808 moves to the dust filter circular hole 810 opened on the surface and aligns with the first circular hole 804, and stops. At this time, the dust in the top-open square shell 1 is The dust will pass through the first circular hole 804 and the dust filter circular hole 810 in turn and be sucked into the square empty shell 801 and discharged from the docking pipe 12. A plurality of dust filter circular holes 810 are opened on the top sliding square plate 808 to separate the dust in the down by suction. After observing that the dust in the top open square shell 1 is almost completely sucked away through the intelligent visual camera 5, the threaded torsion rod 806 is reversed to make the threaded torsion rod 806 move outward and drive the top sliding square plate 808 to move together. When the top sliding square plate 808 moves, it drives the second circular hole 809 opened on the surface to move together. As the top sliding square plate 808 moves, the second circular hole 809 gradually connects and aligns with the first circular hole 804. The gradual connection and alignment of the first circular hole 804 and the second circular hole 809 can be used to filter down feathers of different sizes. The down is sucked in batches, and the top sliding square plate 808 is limited by setting a concave limiting long rod 805 on the top sliding square plate 808. When the square empty shell 801 performs suction-type sorting on the down in the top open square shell 1, the straight electric slide rail 902 drives the inner sliding round rod 903 to move. When the inner sliding round rod 903 moves, it drives the hard brush 904 on the top to move. As the hard brush 904 moves with the inner sliding round rod 903, the inside of the first circular hole 804 and the bottom surface of the built-in square plate 803 are stripped and cleaned. When the hard brush 904 cleans the bottom surface of the built-in square plate 803 and the inside of the first circular hole 804 for a long time, the straight electric slide rail 902 drives the inner sliding round rod 903 to move toward the arc-shaped thorn plate 906.When the inner sliding rod 903 moves to the bottom of the curved thorn plate 906, the hard brush 904 on the top contacts the curved thorn plate 906, and the curved thorn plate 906 performs a piercing and peeling process on the moving hard brush 904. When the hard brush 904 is not in use for cleaning, the straight electric slide rail 902 drives the inner sliding rod 903 to slide to the bottom of the square cover 905.

The square cover 905 is set near the two sides of the bottom of the built-in square plate 803 to cover and protect the hard brush 904.

[0043] A method for automatically sorting large down feathers based on machine vision includes the following steps:

[0044] S1: Place down, place large down in the curved material plate 2 and push it into the top-open square shell 1 for sorting;

[0045] S2: stirring separation, starting the driving motor 3 to drive the stirring separation device 4 to sort the large down in the arc-shaped material plate 2;

[0046] S3: Sorting and suctioning: The vertical electric slide 7 drives the suction sorting device 8 downward and drives the cleaning device 9 at the bottom to move downward together until it contacts the top of the open square shell 1 to form a closed space. Then, the fan 11 is used to make the suction sorting device 8 suck in the dust in the large down and down of different sizes in batches and discharge them from the docking pipe 12;

[0047] S4: Visual monitoring: when sorting large down, the sorted down in the open square shell 1 can be observed by the intelligent visual camera 5;

[0048] S5: cleaning the residual materials. When the suction-type sorting device 8 sucks the down, the cleaning device 9 can scrape and clean the down that is blocked at the bottom.

[0049] When the present invention is in operation, large down is placed in the curved material plate 2 and pushed into the top-open square shell 1. The vertical electric slide rail 7 drives the suction-type sorting device 8 to move downward and drives the cleaning device 9 at the bottom to move downward together until it contacts the top of the top-open square shell 1 to form a closed space. Then, the driving motor 3 is started to drive the stirring separation device 4 to stir the large down in the curved material plate 2 so that the large down is separated. After stirring the large down for a period of time, the fan 11 is used to enable the suction-type sorting device 8 to suck in the dust in the large down and down of different sizes in batches and discharge them from the docking pipe 12. At the same time, when sorting the large down, the intelligent visual camera 5 can be used to observe the sorted down in the top-open square shell 1. When the suction-type sorting device 8 sucks in the down, the cleaning device 9 can be used to scrape and clean the down blocked at the bottom.

[0050] Before the down is sucked in batches, the driving motor 3 is started to drive the linkage long rod 401 to rotate. When the linkage long rod 401 rotates, the slender rod 403 is driven to rotate through the first connecting rod 402. The slender rod 403 drives the small thorn block 404 on the outside to rotate together with the linkage long rod 401. When the slender rod 403 rotates, the long scraping rod 406 is driven to rotate together through the second connecting rod 405 on the outside. When the first connecting rod 402 and the second connecting rod 405 of the linkage long rod 401 rotate, they are initially stirred and torn to separate the large down. The large down stirred and lifted by the first connecting rod 402 and the second connecting rod 405 will come into contact with the rotating slender rod 403 and the long scraping rod 406. A slender rod 403 and a long scraping rod 406 are respectively provided at one end of 05 to fully stir and separate the large down for a second time. When the slender rod 403 rotates with the linked long rod 401, the small thorn blocks 404 on the outside will come into contact with the stirred and separated down and further crush it. The down is torn and crushed by arranging multiple small thorn blocks 404 on the outside of the slender rod 403. When the long scraping rod 406 rotates with the linked long rod 401, it will come into contact with the inner wall of the arc-shaped material plate 2. As the linked long rod 401 rotates, the long scraping rod 406 scrapes and cleans the inner wall of the arc-shaped material plate 2. When the long scraping rod 406 scrapes the inner wall of the arc-shaped material plate 2, the down accumulated on the inner wall of the arc-shaped material plate 2 is lifted up, and the suction is driven by the vertical electric slide 7. The embedded sorting device 8 drives the cleaning device 9 to move downward to contact the top of the top-open square shell 1 to form a closed space with the top-open square shell 1, and then the fan 11 is used to evacuate the square empty shell 801, so that the square empty shell 801 can suck the dust and down in the top-open square shell 1 through the first circular hole 804. When the down in the top-open square shell 1 is sorted and sucked, the threaded torsion rod 806 is twisted to make the threaded torsion rod 806 move in the square empty shell 801 to push the square connecting plate 807 to move. The movement of the square connecting plate 807 drives the top sliding square plate 808 on one side to move until the top sliding square plate 808 moves to the dust filter circular hole 810 opened on the surface and aligns with the first circular hole 804 and stops. At this time, the dust in the top-open square shell 1 will pass through the first circular hole in turn. 804 and the dust filter circular hole 810 are sucked into the square empty shell 801 and discharged from the docking pipe 12. By opening a plurality of dust filter circular holes 810 on the top sliding square plate 808, the dust in the down is separated by suction. After observing that the dust in the top open square shell 1 is almost completely sucked away through the intelligent visual camera 5, the threaded torsion rod 806 is reversed to make the threaded torsion rod 806 move outward and drive the top sliding square plate 808 to move together. When the top sliding square plate 808 moves, it drives the second circular hole 809 opened on the surface to move together. As the top sliding square plate 808 moves, the second circular hole 809 gradually connects and aligns with the first circular hole 804. By gradually connecting and aligning the first circular hole 804 with the second circular hole 809, down of different sizes are sucked in batches.By setting a concave limiting long rod 805 on the top sliding square plate 808 to slide and limit the top sliding square plate 808, when the square empty shell 801 performs suction sorting on the down in the top open square shell 1, the straight electric slide rail 902 drives the inner sliding round rod 903 to move, and when the inner sliding round rod 903 moves, it drives the hard brush 904 on the top to move. As the hard brush 904 moves with the inner sliding round rod 903, the inside of the first circular hole 804 and the bottom surface of the built-in square plate 803 are stripped and cleaned. When the hard brush 904 cleans the bottom surface of the built-in square plate 803 and the inside of the first circular hole 804 for a long time, the straight electric slide rail 902 drives the inner sliding round rod 90 3 moves toward the arc-shaped thorn plate 906. When the inner sliding round rod 903 moves to the bottom of the arc-shaped thorn plate 906, the hard brush 904 on the top contacts the arc-shaped thorn plate 906, and the arc-shaped thorn plate 906 performs a piercing and peeling treatment on the moving hard brush 904. When the hard brush 904 is not in use for cleaning, the straight electric slide rail 902 drives the inner sliding round rod 903 to slide to the bottom of the square blocking cover 905. When the inner sliding round rod 903 slides to the bottom of the square blocking cover 905, the hard brush 904 on the top is squeezed inside the square blocking cover 905. The square blocking covers 905 are set near the two sides of the bottom of the built-in square plate 803 to cover and protect the hard brush 904.
