Description

Technical Field

[0001] This invention relates to the field of color sorting technology, and in particular to an intelligent color sorting machine and method for food processing based on industrial vision. Background Technology

[0002] Intelligent color sorters for food processing are intelligent devices that use optical sensing, artificial intelligence algorithms, and automated control technology to sort food raw materials at high speed and with high precision based on their color, shape, defects, and other characteristics. Their core objective is to replace traditional manual sorting, solving problems such as low efficiency, inconsistent standards, and high hygiene risks. Simultaneously, they improve the consistency of raw material quality and food safety levels, making them one of the key pieces of equipment for achieving standardized, large-scale, and intelligent production in the modern food industry.

[0003] The key to selecting suitable apple pieces using a color sorter is to transform the qualification standards of apple pieces into the intelligent recognition logic of the equipment. Through optical sensing, AI algorithms, and precise execution, efficient screening from raw apple pieces to qualified apple pieces can be achieved.

[0004] The core characteristics of apple pieces are their irregular shape and tendency to stick together. When apple pieces stick together during color sorting, existing technologies often use a vibrating feeder to shake them off. However, if the apple pieces are concentrated and piled up when the material is about to fall onto the vibrating feeder, they will be difficult to shake off, making it easier for them to stick together during color sorting, which can easily affect the accuracy of color sorting.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1.

When the drive shaft moves in the left and right direction, it drives the rotating rod and the agitator fins to rotate. This design can break up the apple pieces that fall in a concentrated manner while moving left and right, and at the same time rotate and break up the apple pieces, further reducing the accumulation of apple pieces on the shaking tray. This reduces the tendency of apple pieces to stick together during color sorting, thereby improving the accuracy of color sorting. 3. The rotating rod drives the agitator to rotate and break up the apple pieces in one direction. Under the combined effect of inertia and directional external force, the material is gradually peeled off and broken up. This not only improves the uniformity and efficiency of the breaking up, but also reduces the accumulation of apple pieces on the shaking tray. This reduces the tendency of apple pieces to stick together during color sorting, thereby improving the accuracy of color sorting. 4. The two separate blocks reciprocate by shaking diagonally upwards in opposite directions to disperse the concentrated falling apple pieces, further reducing the possibility of concentrated falling and thus further reducing the tendency for apple pieces to stick together during color sorting, thereby improving the accuracy of color sorting.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1 to 12 This invention provides a technical solution: an intelligent color sorter for food processing based on industrial vision, comprising a body 1, a material discharge rack 2 mounted on the top of the body 1, a material collection hopper 3 fixedly connected inside the material discharge rack 2, an installation plate 4 fixedly connected inside the material discharge rack 2, a shaking disc 9 disposed above the installation plate 4, a first spring 10 fixedly connected between the installation plate 4 and the shaking disc 9, a vibration motor 11 fixedly connected to the bottom of the shaking disc 9, a chute 12 fixedly connected inside the material discharge rack 2, and the intelligent color sorter further comprising a mixing component 5 disposed inside the material discharge rack 2. 5 includes a rotating rod 51 rotatably connected inside the collecting hopper 3, and an agitating fin plate 52 fixedly connected to the outside of the rotating rod 51. The agitation assembly 5 also includes a sleeve 53 fixedly connected to the left side of the discharge frame 2. A piston plate 54 is movably connected inside the sleeve 53. A second spring 55 is fixedly connected between the piston plate 54 and the sleeve 53. The agitation assembly 5 also includes a first corrugated bladder 56 fixedly connected to the left side between the mounting plate 4 and the shaking disc 9. A first flexible tube 57 is fixedly inserted between the first corrugated bladder 56 and the sleeve 53. A moving rod 58 is fixedly connected to the side of the piston plate 54.

[0022] By adopting the above technical solution, when color sorting is performed, the apple pieces to be color sorted are dropped from the collection hopper 3 inside the dropping rack 2 by an external conveying component. Then, the apple pieces fall above the shaking disc 9, which is tilted. The vibration motor 11 at the bottom of the shaking disc 9 is started, and under the elastic force of the first spring 10, the shaking disc 9 can be shaken continuously to disperse the apples. The dispersed apple pieces fall into the chute 12 through the tilted bottom of the shaking disc 9, and then fall into the color sorting area for screening. The color sorting technology of the color sorter is a mature existing technology. It achieves intelligent and automatic screening through color discrimination, which will not be elaborated further.

[0023] Under the action of the vibrating motor 11, the shaking disc 9 continuously vibrates, causing continuous displacement between the shaking disc 9 and the mounting plate 4. This causes the first bellows 56 to be continuously compressed and stretched, allowing the air medium inside the first bellows 56 to continuously enter or leave the sleeve 53. When the air medium enters the sleeve 53, the piston plate 54 overcomes the elastic force of the second spring 55 and moves to the right. At this time, the piston plate 54, along with the moving rod 58, rotating rod 51, and agitating fin plate 52, moves to the right. When the material moves away from the inside of the sleeve 53, the piston plate 54 moves to the left under the elastic force of the second spring 55. At this time, the piston plate 54 moves to the left along with the moving rod 58, the rotating rod 51 and the stirring fin 52. This design allows the rotating rod 51 and the stirring fin 52 to move continuously in the left and right directions. This design can shake apart the apple pieces that have fallen here, thereby reducing the accumulation of apple pieces on the shaking plate 9 and reducing the tendency of apple pieces to stick together during color sorting, thus improving the accuracy of color sorting.

[0024] It should be noted that the outer side of the agitator fin 52 is covered with rubber to reduce the crushing of apple pieces, thereby reducing the loss of apple pieces.

[0025] The right side of the moving rod 58 is rotatably connected to the drive shaft 59. The outer side of the drive shaft 59 is provided with a guide spiral groove 511. A circular sleeve 512 is arranged on the outer side of the drive shaft 59. A guide slider 513 is fixedly connected to the inner side of the circular sleeve 512. The guide slider 513 moves inside the guide spiral groove 511. The circular sleeve 512 is fixedly connected to the collection hopper 3.

[0026] By adopting the above technical solution, the first corrugated bag 56 is continuously compressed and stretched, which allows the piston plate 54 to move continuously in the left and right direction along the moving rod 58. During this process, the driving shaft 59 moves continuously in the direction of action, which allows relative movement between the driving shaft 59 and the sleeve 512. Through the action of the guide slider 513 moving inside the guide spiral groove 511, the driving shaft 59 can rotate along the left and right direction along the rotating rod 51 and the stirring fin plate 52. This design can achieve the simultaneous dispersing of the concentrated falling apple pieces by the left and right movement and the rotation of the apple pieces, further reducing the accumulation of apple pieces falling on the shaking disc 9, thereby reducing the tendency of apple pieces to stick together during color sorting and improving the accuracy of color sorting.

[0027] A one-way bearing 510 is provided between the right side of the drive shaft 59 and the rotating rod 51, and a rubber ring 514 for increasing friction is fixedly connected to the right side of the collection hopper 3 near the rotating rod 51.

[0028] The right end of the drive shaft 59 is fixed to the outer ring of the one-way bearing 510, and the left end of the rotating rod 51 is connected to the inner ring of the one-way bearing 510. The one-way bearing 510 is a mature existing technology, and its outer ring and inner ring can only rotate in one direction.

[0029] By adopting the above technical solution, when the drive shaft 59 moves to the right, it rotates counterclockwise. Under the action of the guide slider 513 in the guide spiral groove 511, during this rotation, the inner and outer rings of the one-way bearing 510 are locked together, and the inner ring rotates with the outer ring. At this time, the rotating rod 51 rotates with the stirring fin 52 to break up the apple pieces. When the drive shaft 59 moves to the left, it rotates clockwise. Under the action of the guide slider 513 in the guide spiral groove 511, during this rotation, the inner and outer rings of the one-way bearing 510 are not locked together, and the inner ring does not rotate with the outer ring. Under the action of the rubber ring 514, the rotating rod 51 does not rotate with the stirring fin 52.

[0030] This design allows the rotating rod 51 to rotate along the stirring fins 52 in one direction when breaking up the apple pieces. This unidirectional rotation allows the material to tumble and disperse in an orderly manner along a predetermined trajectory in a stable and continuous fluid dynamic field. This avoids the material stress disorder caused by frequent changes in the direction of force during reciprocating rotation, which can easily cause the material to re-aggregate and clump together under the impact of sudden changes in direction, making it difficult to achieve sufficient dispersion. In contrast, the unidirectional rotation, through continuous and uniform shearing and tumbling action, allows the material to be gradually peeled and disassembled under the synergy of inertia and directional external force. This improves the uniformity and efficiency of the dispersal, further reduces the accumulation of apple pieces on the shaking tray 9, and thus reduces the tendency for apple pieces to stick together during color sorting, thereby improving the accuracy of color sorting.

[0031] It should be noted that under the action of the vibrating motor 11, the shaking disc 9 vibrates at a fast speed, which causes the first corrugated bag 56 to be compressed and stretched at a fast speed. This design allows the drive shaft 59 to reciprocate at a relatively fast speed, thereby making the rotating rod 51 rotate with the agitator fin 52 at a relatively fast frequency, which can make the rotation of the rotating rod 51 with the agitator fin 52 more continuous.

[0032] The material discharge rack 2 is internally equipped with a shaking assembly 6. The shaking assembly 6 includes a mounting frame 61 fixedly connected inside the collecting hopper 3 and located above the rotating rod 51. A lifting frame 62 is slidably connected to the top of the mounting frame 61 in a linear array. Separating blocks 63 are slidably connected to both sides of the top of the lifting frame 62. An elastic membrane 64 is fixedly connected between the two separating blocks 63. A fixing frame 65 is fixedly connected to the top of the mounting frame 61. The bottom sides of the fixing frame 65 are inclined. A squeezing frame 66 is fixedly connected to the top of the separating blocks 63. The squeezing frame 66 is located near the inclined part of the fixing frame 65. A device for reducing [damage / loss] is rotatably connected to the top of the squeezing frame 66. The small shaft 67 of the motion friction component 6 also includes a long plate 68 rotatably connected to the outside of the drive shaft 59. A long rod 69 is fixedly connected to the side of the long plate 68. The long rod 69 is slidably connected to the unloading frame 2. The long rod 69 extends into the interior of the mounting frame 61 and is fixedly connected to a pressing rod 610. The end of the pressing rod 610 is rotatably connected to a ball for reducing motion friction. An inclined block 611 is fixedly connected to the bottom of the lifting frame 62. The bottom of the inclined block 611 is inclined. A magnetic block 612 is fixedly connected to the interior of the separating block 63 near the lifting frame 62. The part of the lifting frame 62 near the magnetic block 612 is made of iron.

[0033] In the initial state, under the elastic force of the elastic membrane 64 and the magnetic force of the magnetic block 612, the two separating blocks 63 are in a closed state. At this time, the separating blocks 63 are located in a lower position, and the small shaft 67 on the extrusion frame 66 abuts against the inclined part of the fixed frame 65. At this time, the inclined block 611 is located in a lower position.

[0034] By adopting the above technical solution, when the drive shaft 59 moves back and forth in the left and right direction, the long plate 68 can move back and forth in the left and right direction along with the long rod 69. At this time, the extrusion rod 610 moves along with it and can extrude the inclined surface of the inclined block 611, so that the lifting frame 62 can move upward with the separating block 63. During this process, the small shaft 67 on the extrusion frame 66 is limited by the inclined part of the fixed frame 65, which can make the two separating blocks 63 overcome the elastic force of the elastic membrane 64 and the magnetic force of the magnetic block 612 and move in a direction away from each other. This design can make the two separating blocks 63 reciprocate and shake in a diagonally upward direction away from each other, thereby shaking apart the concentrated falling apple pieces, further reducing the possibility of concentrated falling, and further reducing the situation that apple pieces are more likely to stick together during color sorting, thereby improving the accuracy of color sorting.

[0035] The middle part of the rotating rod 51 is rotatably connected to a ring 7, and the outer side of the ring 7 is fixedly connected to a moving frame 8. The outer side of the moving frame 8 is fixedly connected to a scraper 13 in a linear array. The scraper 13 is attached to the inner side of the collecting hopper 3, and the outer side of the scraper 13 is covered with rubber material.

[0036] By adopting the above technical solution, when the shaft 59 moves back and forth in the left and right direction, the ring 7 can move back and forth in the left and right direction along with the moving frame 8 and the scraper 13. The scraper 13 can scrape the inside of the collecting hopper 3 to prevent apple pieces from sticking to the inside of the collecting hopper 3. At the same time, the movement of the scraper 13 can break up the apple pieces, reducing the tendency for apple pieces to stick together during color sorting, thereby improving the accuracy of color sorting.

[0037] A second corrugated bladder 14 is fixedly connected to the left side between the mounting plate 4 and the shaking disc 9. A spray hood 15 is fixedly connected to the inner side of the mounting plate 4. The bottom of the spray hood 15 has a spray hole. A second flexible tube 16 is fixedly connected between the spray hood 15 and the second corrugated bladder 14. An inlet tube 17 is fixedly inserted into the bottom of the second corrugated bladder 14. Both the inlet tube 17 and the second flexible tube 16 are equipped with check valves 18. The check valves 18 are mature existing technologies. The check valves 18 at the inlet tube 17 do not allow the medium inside the second corrugated bladder 14 to be discharged from the inlet tube 17. The check valves 18 inside the second flexible tube 16 do not allow the medium inside the spray hood 15 to return to the inside of the second corrugated bladder 14.

[0038] By adopting the above technical solution, when the vibration motor 11 is activated, the material shaking disc 9 will continuously vibrate, causing continuous displacement between the material shaking disc 9 and the mounting plate 4. At this time, the second corrugated bladder 14 will be continuously compressed and stretched. When the second corrugated bladder 14 is stretched, the external medium enters the interior of the second corrugated bladder 14 from the inlet pipe 17. When the second corrugated bladder 14 is compressed, the medium is discharged from the spray hole of the spray hood 15.

[0039] During testing, air is introduced into the end of the inlet pipe 17. The air spray helps to further disperse the apple pieces, further reducing the accumulation of apple pieces on the shaking tray 9. This reduces the tendency for apple pieces to stick together during color sorting, thereby improving the accuracy of color sorting.

[0040] During cleaning, a water source is connected to the end of the inlet pipe 17, so that during cleaning, the water flows to the bottom inner side of the collection hopper 3, and the scraper 13 scrapes and cleans the inner side of the collection hopper 3.

[0041] A smart color sorting method for food processing based on industrial vision includes the following steps: S1. Feeding: The apple pieces that need to be color sorted are fed into the collection hopper 3 inside the feeding rack 2 by the external conveying component. Then the apple pieces fall on the shaking disc 9. The shaking disc 9 is set at an angle. The vibration motor 11 at the bottom of the shaking disc 9 is started. Under the elastic force of the first spring 10, the shaking disc 9 can be shaken continuously. S2. Screening: The shaken apple pieces fall into the chute 12 through the tilted bottom of the shaking tray 9, and then fall into the color sorting area for screening.

[0042] Working principle: Under the action of the vibrating motor 11, the shaking disc 9 continuously vibrates, causing continuous displacement between the shaking disc 9 and the mounting plate 4. This causes the first bellows 56 to be continuously compressed and stretched, allowing the air medium inside the first bellows 56 to continuously enter or leave the sleeve 53. When the air medium enters the sleeve 53, the piston plate 54 overcomes the elastic force of the second spring 55 and moves to the right. At this time, the piston plate 54, along with the moving rod 58, rotating rod 51, and agitating fins 52, moves to the right. When the air medium moves away from the sleeve 53, the piston plate 54 moves to the left under the elastic force of the second spring 55. The piston plate 54 moves the moving rod 58, the rotating rod 51, and the agitating fin 52 to the left. This design allows the rotating rod 51 and the agitating fin 52 to move continuously in the left and right directions. Through the action of the guide slider 513 moving inside the guide spiral groove 511, the driving shaft 59 can rotate the rotating rod 51 and the agitating fin 52 when it moves in the left and right directions. This design can achieve the simultaneous dispersing of the concentrated falling apple pieces by the left and right movement and the rotation of the apple pieces, further reducing the accumulation of apple pieces on the shaking disc 9, thereby reducing the tendency of apple pieces to stick together during color sorting and improving the accuracy of color sorting.

[0043] When the drive shaft 59 moves to the right, it rotates counterclockwise. Under the action of the guide slider 513 in the guide spiral groove 511, the inner and outer rings of the one-way bearing 510 are locked during this rotation. The inner ring rotates with the outer ring. At this time, the rotating rod 51 rotates with the stirring fin 52 to break up the apple pieces. When the drive shaft 59 moves to the left, it rotates counterclockwise. Under the action of the guide slider 513 in the guide spiral groove 511, the inner and outer rings of the one-way bearing 510 are not locked during this rotation. The inner ring does not rotate with the outer ring. Under the action of the rubber ring 514, the rotating rod 51 does not rotate with the stirring fin 52. This design allows the rotating rod 51 to rotate with the stirring fin 52 in one direction when breaking up the apple pieces.

[0044] When the drive shaft 59 reciprocates in the left and right direction, the long plate 68, along with the long rod 69, reciprocates in the left and right direction. At this time, the squeezing rod 610 moves along with it and squeezes the inclined surface of the inclined block 611, which causes the lifting frame 62 to move upward with the separating block 63. During this process, the small shaft 67 on the squeezing frame 66 is limited by the inclined part of the fixed frame 65, which allows the two separating blocks 63 to overcome the elastic force of the elastic membrane 64 and the magnetic force of the magnetic block 612 and move in a direction away from each other. This design allows the two separating blocks 63 to reciprocate and shake in a diagonally upward direction away from each other, thereby scattering the concentrated falling apple pieces.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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; and these 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 the present invention.
