Description

Technical Field

[0001] This invention relates to the field of jewelry color sorting technology, and in particular to a jewelry color sorting device and method with dual-axis collaborative control. Background Technology

[0002] Color sorters are devices that automatically separate particles of different colors based on differences in the optical properties of materials using photoelectric detection technology. They are currently widely used for grading and quality inspection of bulk materials, industrial products, and food. However, in the color sorting application of jewelry, especially small spherical jewelry, existing color sorting devices still have certain technical limitations.

[0003] For example, application CN110721931A discloses a color sorting device and its application in jewelry color sorting, specifically including a material receiving and distributing mechanism, a material guiding and sorting mechanism, and a color sorting and identification mechanism. The material receiving and distributing mechanism conveys materials to a slotted notch on the edge of a turntable via a double-hole storage connector, enabling the materials to be discharged one by one. However, in practical applications, due to the significant differences in the diameter range of jewelry materials, if color sorting is performed directly without pre-screening, the following problems are likely to occur:

[0004] When the diameter of the jewelry is small, the double-hole storage connector may feed two or more jewelry into the same slot at the same time, which may cause the color sorting and identification mechanism to be unable to accurately identify the color information of a single jewelry, thus affecting the sorting accuracy.

[0005] To avoid the above problems, existing technologies usually require the addition of a screening device before color sorting to pre-group the jewelry according to particle size, and then replace the double-hole storage joint with the corresponding inner diameter according to different particle size ranges.

[0006] This process not only increases the complexity of the equipment and the number of operating steps, but also significantly reduces color sorting efficiency and increases labor and time costs. Summary of the Invention

[0007] This invention provides a dual-axis collaborative control device and method for jewelry color sorting, which can solve the following problems existing in the prior art:

[0008] In the process of color sorting jewelry, if the particle size of the jewelry differs greatly, it is not possible to feed each piece individually, which will affect the normal progress of the testing.

[0009] A dual-axis collaborative control jewelry color sorting device includes a color sorting platform, on which a first color sorting section and a second color sorting section are symmetrically arranged for color sorting and classification of jewelry;

[0010] The color sorting table is also equipped with a collection hopper for temporary storage of jewelry to be sorted. The collection hopper is equipped with a multi-stage screening module for grading jewelry with different particle size ranges.

[0011] The bottom of the collecting hopper is symmetrically provided with two sets of discharge ports, which are respectively connected to the conveying module to transport the graded jewelry to the first color sorting section and the second color sorting section.

[0012] Preferably, the multi-stage screening module includes a first screen plate, a second screen plate, and a third screen plate arranged sequentially from top to bottom in the hopper. The first screen plate is provided with a first screen hole, the second screen plate is provided with a second screen hole, and the third screen plate is provided with a third screen hole.

[0013] The apertures of the first, second, and third sieve holes gradually decrease.

[0014] Preferably, the multi-stage screening module further includes an adjustment mechanism, which is used to sequentially drive the third sieve plate, the second sieve plate, and the first sieve plate to rotate.

[0015] Preferably, the material conveying module includes a stirring hopper connected to the discharge port, the bottom of the stirring hopper being connected to a discharge pipe, and the inner diameter of the discharge pipe being larger than the aperture of the first sieve.

[0016] The discharge pipe has a discharge plate slidably mounted at its bottom, which slides and fits into the discharge pipe. The bottom of the discharge plate is sequentially fixed with a first guide tube, a second guide tube, a third guide tube, and a fourth guide tube. The inner diameters of the first, second, third, and fourth guide tubes gradually increase. The discharge plate is also provided with receiving holes connected to each guide tube. The diameter of each receiving hole is the same as the inner diameter of the corresponding guide tube. The material conveying module also includes a drive cylinder fixed on the color sorting table. The drive end of the drive cylinder is fixed to the discharge plates on both sides through a connecting plate.

[0017] Preferably, the adjusting mechanism includes a support shaft fixed to one side of each screen plate, and the two ends of the support shaft connected to the first screen plate pass through the side wall of the hopper and are fixed to the first gear, the two ends of the support shaft connected to the second screen plate pass through the side wall of the hopper and are fixed to the second gear, and the two ends of the support shaft connected to the third screen plate pass through the side wall of the hopper and are fixed to the third gear.

[0018] The hopper is provided with symmetrical adjustment plates on both sides. The two adjustment plates are connected to the lifting mechanism that drives them to rise and fall. The adjustment plates are sequentially fixed with a first rack for meshing with the first gear, a second rack for meshing with the second gear, and a third rack for meshing with the third gear.

[0019] Preferably, the lifting mechanism includes a guide rod fixed to the hopper, a guide plate slidably sleeved on the guide rod and fixedly connected to the two side adjustment plates, the bottom end of the guide rod slidably connected to the lifting plate, the lifting plate being fixed to the guide plate by the lifting rod, inclined plates being symmetrically fixedly arranged on both sides of the lifting plate, and a telescopic spring being provided on the guide rod.

[0020] The ends of the discharge plates on both sides are fixedly provided with limiting rods, and the ends of the limiting rods are rotatably provided with guide wheels that roll and abut against the inclined plates.

[0021] Preferably, each of the screen plates is fixedly provided with a U-shaped baffle, and the open end of the U-shaped baffle is also provided with a sealing plate, which is connected to the rotating mechanism that drives it to rotate.

[0022] Preferably, the sealing plate is rotatably mounted at the open end of the U-shaped baffle, and the rotating mechanism includes adjusting gears fixed at both ends of the sealing plate, with arc-shaped racks meshing with the adjusting gears correspondingly fixed on both sides inside the hopper.

[0023] Preferably, both the first color sorting unit and the second color sorting unit include a rotating spiral roller, the spiral roller having a spiral groove for conveying jewelry, and the spiral roller being fixed to the output end of a servo motor that drives its rotation.

[0024] Among them, a number of push blocks are arranged adjacent to each other on one side of the spiral roller, and each push block is fixedly connected to the drive end of the electromagnetic lock fixed on the color sorting table. Color sorting cameras are also arranged symmetrically on the color sorting table.

[0025] A color sorting method for a jewelry color sorting device with dual-axis collaborative control includes the following steps:

[0026] Pour the jewelry to be color sorted into the collection hopper;

[0027] Jewelry is pre-screened using a multi-stage screening module set in the collection hopper;

[0028] After pre-screening, the jewelry in the hopper can be discharged to the conveying module through the discharge port under the action of gravity;

[0029] The material conveying module transports the jewelry to the first and second color sorting sections for color sorting and classification.

[0030] This invention provides a dual-axis collaborative control device and method for jewelry color sorting, which has the following beneficial effects:

[0031] 1) After pre-screening, the jewelry in the hopper of this invention can be discharged to the conveying module through the discharge port under gravity, and then conveyed to the first color sorting section and the second color sorting section for color sorting and classification. Compared with the prior art of using a screening machine to screen jewelry, this invention integrates a multi-stage screening module into the hopper of the color sorter, avoiding the cumbersome screening process. At the same time, by setting two sets of color sorting sections, this invention can perform jewelry color sorting processing at the same time, further improving the color sorting efficiency.

[0032] 2) In this invention, after all the jewelry at the bottom of the hopper has been sorted by color, the first batch of jewelry sorting is completed. The third screen plate can be driven downward by a certain angle through the adjustment mechanism, so that the jewelry on the third screen plate can be discharged to the bottom of the hopper under the action of gravity to complete the second batch of jewelry sorting. Correspondingly, after the jewelry on the third screen plate has been sorted by color, the second screen plate can be driven downward by a certain angle through the adjustment mechanism to sort the jewelry on the second screen plate to complete the third batch of jewelry sorting. Similarly, the jewelry on the first screen plate is sorted by color to complete the fourth batch of jewelry sorting. Therefore, this invention sorts the jewelry by multiple screen plates and then outputs the jewelry on each screen plate in sequence through each adjustment mechanism to achieve the effect of batch color sorting and screening. The degree of automation is higher and the screening efficiency is effectively improved.

[0033] 3) In the initial state, the first conduit is connected to the discharge pipe, allowing for color sorting of the first batch of jewelry in the hopper. After the first batch is sorted, the discharge plate is slid by a drive cylinder to connect the second conduit to the discharge pipe, completing the color sorting of the second batch. After that, the discharge plate is slid by a drive cylinder to connect the third conduit to the discharge pipe, completing the color sorting of the third batch. After that, the discharge plate is slid by a drive cylinder to connect the fourth conduit to the discharge pipe, finally completing the color sorting of the fourth batch. Throughout the jewelry color sorting process, this invention can adjust the connection between conduits of different inner diameters and the discharge pipe in real time based on the pre-screening status of the jewelry using a multi-level screening module. This allows for the sequential conveying of jewelry of different grades to the color sorting section. This invention eliminates the need for manual switching of the conduits, resulting in a higher degree of automation. Attached Figure Description

Detailed Implementation

[0045] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0046] Example 1

[0047] like Figures 1 to 4As shown in the figure, the present invention provides a dual-axis collaborative control jewelry color sorting device, including a color sorting platform 1, on which a first color sorting part 3 and a second color sorting part 301 are symmetrically arranged for color sorting and classification of jewelry.

[0048] Specifically, the color sorting station 1 is also equipped with a collection hopper 2 for temporarily storing jewelry to be sorted. The collection hopper 2 is equipped with a multi-stage screening module for grading jewelry of different particle size ranges. It can be explained that in this embodiment, the jewelry to be sorted is poured into the collection hopper 2, and the jewelry is pre-screened by the multi-stage screening module set in the collection hopper 2 so that it can be finely classified by the color sorter in the future.

[0049] Please refer to Figures 4-7 The bottom of the collecting hopper 2 is symmetrically provided with two sets of discharge ports 204. The two sets of discharge ports 204 are respectively connected to the conveying module to convey the graded jewelry to the first color sorting unit 3 and the second color sorting unit 301.

[0050] It should also be noted that, after pre-screening, the jewelry in the hopper 2 of this embodiment can be discharged to the conveying module through the discharge port 204 under the action of gravity, and then conveyed to the first color sorting unit 3 and the second color sorting unit 301 for color sorting and classification. Compared with the prior art of using a screening machine to screen jewelry, this embodiment integrates a multi-stage screening module into the hopper of the color sorter, avoiding the cumbersome screening process. At the same time, by setting up two sets of color sorting units, this embodiment can perform jewelry color sorting processing at the same time, further improving the color sorting efficiency.

[0051] Example 2

[0052] Based on Example 1, please refer to Figures 6-9 The multi-stage screening module includes a first screen plate 8, a second screen plate 810, and a third screen plate 812 arranged sequentially from top to bottom in the collecting hopper 2. The first screen plate 8 has first screen holes 802 evenly spaced, the second screen plate 810 has second screen holes 811 evenly spaced, and the third screen plate 812 has third screen holes 813 evenly spaced. The apertures of the first screen holes 802, second screen holes 811, and third screen holes 813 gradually decrease. It can be noted that in this embodiment, when sorting the color of jewelry, [the following is a description of the module's function]... Jewelry awaiting color sorting is first poured onto the first sieve plate 8, where it undergoes primary screening through the first sieve hole 802. Jewelry with a particle size smaller than the first sieve hole 802 falls onto the second sieve plate 810, where it undergoes secondary screening through the second sieve hole 811. Jewelry with a particle size smaller than the second sieve hole 811 falls onto the third sieve plate 812, while jewelry with a particle size smaller than the third sieve hole 813 falls to the bottom of the collecting hopper 2. This ensures that during the screening process, the jewelry that falls to the bottom of the collecting hopper 2 is screened first.

[0053] In addition, in order to improve the screening efficiency of each screen plate for jewelry, a vibrating motor can be installed on the collecting hopper 2 to vibrate the collecting hopper 2 and improve the screening efficiency of each screen plate. In this embodiment, the specific model and principle of the vibrating motor are not limited, as long as they meet the actual application requirements.

[0054] As one implementation of this embodiment, the multi-stage screening module also includes an adjustment mechanism, which is used to sequentially drive the third screen plate 812, the second screen plate 810, and the first screen plate 8 to rotate. It can be noted that in this embodiment, after all the jewelry at the bottom of the collecting hopper 2 has been color-sorted, the color sorting of the first batch of jewelry is complete. This can be achieved by first driving the third screen plate 812 downwards at a certain angle using the adjustment mechanism (see reference...). Figure 9 This allows the jewelry on the third screen plate 812 to be discharged to the bottom of the collecting hopper 2 under the action of gravity, thus completing the color sorting of the second batch of jewelry. Correspondingly, after the jewelry on the third screen plate 812 is color sorted, the second screen plate 810 is driven to deflect downward by a certain angle through the adjustment mechanism to color sort the jewelry on the second screen plate 810, thus completing the color sorting of the third batch of jewelry. Similarly, the jewelry on the first screen plate 8 is color sorted last, thus completing the color sorting of the fourth batch of jewelry. Therefore, in this embodiment, after the jewelry is screened by multi-stage screen plates, the jewelry on each screen plate is output sequentially through each adjustment mechanism to achieve the effect of batch color sorting and screening, which has a higher degree of automation and effectively improves screening efficiency.

[0055] In this embodiment, to output each batch of jewelry one by one, please refer to... Figures 2-4 as well as Figure 6The material conveying module includes a mixing hopper 201 connected to the discharge port 204. The bottom of the mixing hopper 201 is connected to a discharge pipe 203. The inner diameter of the discharge pipe 203 is larger than the aperture of the first sieve hole 802. A discharge plate 601 is slidably disposed at the bottom of the discharge pipe 203. The discharge plate 601 is slidably attached to the discharge pipe 203. A first guide tube 602, a second guide tube 603, a third guide tube 604, and a fourth guide tube 605 are sequentially fixedly arranged at the bottom of the discharge plate 601. The inner diameters of pipe 602, the second conduit 603, the third conduit 604, and the fourth conduit 605 gradually increase. The discharge plate 601 is also provided with receiving holes 607 connected to each conduit. The diameter of each receiving hole 607 is the same as the inner diameter of the corresponding conduit. The material conveying module also includes a drive cylinder 606 fixed to the color sorting station 1. The drive end of the drive cylinder 606 is fixed to the discharge plates 601 on both sides via a connecting plate. It can be noted that, in the initial state, the first conduit 602... When connected to the discharge pipe 203, the first batch of jewelry in the collection hopper 2 can be color-sorted. After the first batch of jewelry is color-sorted, the discharge plate 601 can be slid by the drive cylinder 606 to connect the second conduit 603 to the discharge pipe 203, thus completing the color sorting of the second batch of jewelry. After that, the drive cylinder 606 drives the discharge plate 601 to slide, thus connecting the third conduit 604 to the discharge pipe 203, thus completing the color sorting of the third batch of jewelry. After that, the drive cylinder 606 drives the discharge plate 601 to slide, thus connecting the fourth conduit 605 to the discharge pipe 203, thus completing the color sorting of the fourth batch of jewelry. In this embodiment, during the entire jewelry color sorting process, the connection between the conduits with different inner diameters and the discharge pipe 203 can be adjusted in real time based on the pre-screening status of the jewelry by the multi-level screening module, thereby achieving the effect of conveying jewelry of different grades one by one to the color sorting section. This embodiment does not require manual switching of the conduits, resulting in a higher degree of automation.

[0056] In addition, in order to ensure that the jewelry in the mixing hopper 201 can fall stably to the discharge pipe 203, in this embodiment, the mixing hopper 201 is provided with mixing blades, and the mixing blades are fixedly connected to the output end of the mixing motor 202 fixed on the mixing hopper 201; specifically, after the jewelry falls into the mixing hopper 201, the mixing motor 202 can drive the mixing blades to rotate to mix the jewelry, so that the jewelry can fall quickly towards the discharge pipe 203.

[0057] Please refer to Figures 2-3 as well as Figures 5-7The adjusting mechanism includes a support shaft 801 fixed to one side of each screen plate. The two ends of the support shaft 801 connected to the first screen plate 8 pass through the side wall of the collecting hopper 2 and are fixed to the first gear 513. The two ends of the support shaft 801 connected to the second screen plate 810 pass through the side wall of the collecting hopper 2 and are fixed to the second gear 512. The two ends of the support shaft 801 connected to the third screen plate 812 pass through the side wall of the collecting hopper 2 and are fixed to the third gear 803. Adjusting plates 502 are symmetrically arranged on both sides of the collecting hopper 2. The two adjusting plates 502 are connected to the drive... The lifting mechanism is connected to the adjusting plate 502, and a first rack 511 for meshing with the first gear 513, a second rack 510 for meshing with the second gear 512, and a third rack 509 for meshing with the third gear 803 are sequentially fixed on the adjusting plate 502. In the initial state, the distance between the third gear 803 and the third rack 509, the distance between the second gear 512 and the second rack 510, and the distance between the first gear 513 and the first rack 511 gradually decrease. It can be explained that in the initial state... In the initial state, the distance between the third gear 803 and the third rack 509 is the smallest. When the lifting mechanism drives the adjusting plate 502 to rise, the third rack 509 drives the third screen plate 812 to deflect downward by a certain angle by meshing with the third gear 803. As the adjusting plate 502 continues to rise, the second rack 510 meshes with the second gear 512, thereby driving the second screen plate 810 to deflect downward by a certain angle. When the adjusting plate 502 continues to rise, the first gear 513 meshes with the first rack 511, thereby driving the first screen plate 8 to deflect downward by a certain angle. Therefore, in this embodiment, only the lifting mechanism needs to drive the adjusting plate 502 to rise to achieve the effect of sequentially driving the third screen plate 812, the second screen plate 810, and the first screen plate 8 to deflect. This embodiment does not require setting up multiple servo drive devices to adjust different screen plates for deflection, which not only reduces production costs but also ensures the stability of the sequential deflection of each screen plate. Correspondingly, when the lifting mechanism drives the adjusting plate 502 to fall, it can synchronously drive each screen plate to return to its horizontal position.

[0058] For details, please refer to Figures 2-3 as well as Figures 5-7The lifting mechanism includes a guide rod 5 fixed to the hopper 2. A guide plate 501, fixedly connected to two side adjusting plates 502, is slidably sleeved on the guide rod 5. The bottom end of the guide rod 5 is slidably connected to the lifting plate 504. The lifting plate 504 is fixed to the guide plate 501 via a lifting rod 508. Inclined plates 505 are symmetrically fixed on both sides of the lifting plate 504. A telescopic spring 503 is also provided on the guide rod 5. One end of the telescopic spring 503 is fixed to the lifting plate 504, and the other end is fixed to the guide plate 501. Limiting rods 507 are fixedly arranged at the ends of the two side discharge plates 601. Guide wheels 506, which roll and abut against the inclined plates 505, are rotatably arranged at the ends of the limiting rods 507. It can be noted that the driving electric cylinder 606 in this embodiment drives the first conduit 602, the second conduit 603, the third conduit 604, and the fourth conduit 605... During the connection of the discharge pipe 203, the discharge plate 601 synchronously drives the guide wheel 506 to move via the limit rod 507. The guide wheel 506 drives the lifting plate 504 to gradually rise by rolling against the inclined plate 505. The lifting plate 504 then drives the guide plate 501 to rise on the guide rod 5 via the lifting rod 508, so as to stretch the telescopic spring 503 and generate elastic force. Then, the guide plate 501 drives the two side adjustment plates 502 to rise. Correspondingly, when the drive end of the drive cylinder 606 is reset, the telescopic spring 503 can synchronously drive each component to reset. Based on this, in the process of adjusting each guide pipe to be connected to the discharge pipe 203 in sequence, the drive cylinder 606 of this embodiment can realize the effect of synchronously adjusting the rotation of each screen plate in sequence, without the need to set up other servo drive equipment to drive the adjustment plate 502 to rise and fall, thus achieving higher synchronization and stability.

[0059] Furthermore, when each rack drives the gear to rotate, as the rack and gear lose meshing, to prevent the gear from rotating on its own, in this embodiment, the end of each gear away from the hopper 2 is fixed to the telescopic rod 805, and the other end of the telescopic rod 805 is slidably inserted into the sleeve 807. Several sets of strip-shaped card seats 806 are fixedly arranged in a circumferential array on the telescopic rod 805, and the sleeve 807 is correspondingly provided with strip-shaped slots that slide and engage with the strip-shaped card seats 806 one by one. The other end of the sleeve 807 is fixed to the screw 808. The hopper 2 is fixedly provided with an L-shaped bracket 804 that is helically connected to the screw 808. It can be explained that when the gear rotates, the telescopic rod 805 and the sleeve 807 can synchronously drive the screw 808 to rotate in the L-shaped bracket 804. Since the rotation of the screw 808 requires a certain torsional force, the gear will not rotate on its own when the rack is not meshing with the gear, resulting in higher stability.

[0060] Please see Figures 1-4Both the first color sorting unit 3 and the second color sorting unit 301 include a rotating spiral roller 4. The spiral roller 4 has a spiral groove 401 for conveying jewelry. The spiral roller 4 is fixed to the output end of a servo motor 404 that drives its rotation. Several sets of push blocks 403 are arranged adjacent to each other on one side of the spiral roller 4. Each push block 403 is fixedly connected to the drive end of an electromagnetic lock 402 fixed on the color sorting table 1. Color sorting cameras 6 are also symmetrically arranged on the color sorting table 1. It can be noted that, in this embodiment, after the jewelry is output through the conduit, it can be discharged into the spiral groove 401 of the spiral roller 4 for conveying. During the transport process, images of the jewelry can be acquired and analyzed by the color sorting camera 6. Based on the classification results and coordinates output by the algorithm, the controller immediately calculates the precise motion timing. When the jewelry arrives at the designated sorting position, the controller will control the corresponding electromagnetic lock 402 to drive the push block 403 to retract under the precise timing, so that the jewelry can fall into the sorting channel corresponding to the push block 403 for collection. In this embodiment, each spiral roller 4 is equipped with 40 electromagnetic locks 402 for independent control, which can realize the precise sorting of 40 types of jewelry. This color sorting process is existing technology and will not be described in detail.

[0061] As a further solution in this embodiment, please refer to Figures 6-9 In the process of pre-screening jewelry, in order to prevent jewelry from rolling off the edge of the screen plate, U-shaped baffles 816 are fixedly arranged on each screen plate. The opening end of the U-shaped baffle 816 is also provided with a sealing plate 809, which is connected to the rotating mechanism that drives it to rotate. It can be explained that when each screen plate is in a horizontal state, the U-shaped baffle 816 and the sealing plate 809 form a limiting space to prevent jewelry on the screen plate from rolling off the edge. When it is necessary to discharge the jewelry on the screen plate for screening, as the screen plate deflects downward, the rotating mechanism can synchronously drive the sealing plate 809 to deflect downward, so that the jewelry on the screen plate can roll off from the opening of the U-shaped baffle 816.

[0062] Specifically, the sealing plate 809 is rotatably mounted at the opening end of the U-shaped baffle 816. The rotating mechanism includes adjusting gears 814 fixed at both ends of the sealing plate 809. Arc-shaped racks 815 that mesh with the adjusting gears 814 are correspondingly fixedly arranged on both sides inside the hopper 2. It can be explained that when the screen plate deflects downward, the adjusting gears 814 can be driven to move synchronously. The adjusting gears 814 can drive the sealing plate 809 to rotate by meshing with the arc-shaped racks 815, so as to open the opening of the U-shaped baffle 816 and facilitate the discharge of jewelry. Based on this, this embodiment does not need to set up other servo drive equipment to adjust the rotation of the sealing plate 809. With the deflection of the screen plate, the deflection of the sealing plate 809 can be automatically adjusted, which has high stability and reduces costs.

[0063] Furthermore, in order to transport the jewelry discharged from the conduit into the spiral groove 401 of the spiral roller 4, please refer to... Figure 2 The color sorting station 1 is equipped with a baffle plate 701 for receiving jewelry discharged from the conduit. The baffle plate 701 is fixedly connected to the output end of the baffle motor 7 that drives it to swing back and forth. It can be explained that after the jewelry is discharged through the conduit, it can fall onto the baffle plate 701. As the baffle motor 7 drives the baffle plate 701 to swing in the direction of the spiral roller 4, the jewelry can roll into the spiral groove 401 of the spiral roller 4, thus achieving the effect of feeding.
