[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] When the track conveyor transports materials, the pigments from the materials will adhere to the track. When the color sorter sorts the materials by color, the pigments on the track may affect the sorting of materials by the color sorter, which is not conducive to improving the sorting accuracy of the color sorter. In addition, the track needs to be maintained regularly after dyeing, which brings inconvenience to the operation of the color sorter.

[0019] Therefore, this utility model proposes a color sorter 100 with a pigment removal component 2, which can remove pigments on the track 10, thereby greatly reducing the problem of the track 10 being stained and improving the accuracy of the color sorter 100 in sorting materials.

[0020] Combination Figures 1 to 5 According to an embodiment of the present invention, a color sorter 100 includes a conveying device 1 and a pigment removal component 2. The conveying device 1 includes a conveyor belt 10 for conveying materials, and the pigment removal component 2 includes at least one ultraviolet lamp 21 that acts on the rotational idle section of the conveyor belt 10. Specifically, during operation, the conveyor belt 10 receives materials at the feed point and transports them to the discharge point to eject the materials, thereby forming the rotational carrying section of the conveyor belt 10. The remaining section without material is the rotational idle section. The pigment removal component 2 acts on the rotational idle section of the conveyor belt 10, meaning that the pigment removal component 2 can act directly on the conveyor belt 10 without being obstructed by materials, thereby improving the pigment removal effect on the conveyor belt 10.

[0021] More specifically, the pigment removal component 2 includes an ultraviolet lamp 21, which is used to irradiate the track 10 to decompose the pigments adhering to the track 10, thereby preventing pigment accumulation and discoloration of the track.

[0022] When the pigment removal component 2 includes two or more ultraviolet lamps 21, the intensity of the ultraviolet lamps 21 irradiating the idle section of the track 10 during rotation can be increased, thereby improving the pigment removal effect or increasing the area irradiated by the ultraviolet lamps 21 within the idle section of the track 10 during rotation, thereby improving the pigment removal efficiency. Furthermore, utilizing the time and area of ​​the track 10's movement within the idle section for pigment removal does not affect the normal operation of the conveying device 1, nor does it occupy the conveying space of the conveying device 1, thus facilitating the arrangement of the pigment removal component 2.

[0023] According to the color sorter 100 of this utility model embodiment, by setting the pigment removal component 2, the pigments attached to the material on the track 10 can be removed in the rotation idle range of the track 10, thereby improving the cleanliness of the track 10 and improving the accuracy of material sorting on the track 10.

[0024] When the conveyor 1 transports food such as carrots, tomatoes, red peppers, corn, and leafy greens, the carotene adhering to the track 10 can be removed by the pigment removal component 2 during the idle rotation of the track 10. When the conveyor 1 transports blueberries or strawberries, the phenolic pigments adhering to the track 10 can be removed by the pigment removal component 2 during the idle rotation of the track 10.

[0025] In the rotating cargo area of ​​the track 10, the track 10 can be used to carry and transport food, and the color sorter 100 can sort the food during the transportation process. During the transportation of food in the rotating cargo area, it comes into contact with the track 10, and the pigments in the food or materials will adhere to the track 10, causing contamination of the track 10. Because the track 10 is stained by pigments, it affects the accuracy of the color sorter 100 in sorting food or materials by color.

[0026] By setting ultraviolet lamps 21 in the idle rotation section of the track 10, the ultraviolet lamps 21 can irradiate the track 10 when it is not transporting food, and produce a photo-oxidation reaction with the pigments on the track 10, thereby decomposing the pigments. In this way, when the track 10 rotates to the rotating loading section again, it will not affect the sorting of materials by the color sorter 100 when transporting food.

[0027] Combination Figure 1 In some embodiments of this utility model, an ultraviolet lamp 21 is provided at least at the front end of the idle rotation section of the track 10. In this way, the ultraviolet light can decompose the pigments on the track 10 more quickly after the track 10 runs into the idle rotation section, which helps to reduce the time that the pigments stay on the track 10, and thus makes it easier to remove the pigments from the track 10.

[0028] Specifically, the track 10 has a first end that moves from the rotating cargo section to the rotating idle section and a second end that moves from the rotating idle section to the rotating cargo section. The ultraviolet lamp 21 is located near the first end, i.e., the front end of the rotating idle section of the track 10. In this way, after transporting food, the track 10 moves from the rotating cargo section to the rotating idle section, allowing for timely ultraviolet irradiation of the track 10 after food transport, reducing the time pigments remain on the track 10, thus facilitating the decomposition of pigments on the track 10 by ultraviolet light. Furthermore, the range or duration of ultraviolet irradiation can be increased. For example, the ultraviolet light can be applied only near the first end of the track 10, or it can be applied from the first end to the second end, increasing the irradiation time to enhance the decomposition effect of ultraviolet light on the pigments on the track 10.

[0029] Combination Figure 1 In some embodiments of this utility model, the pigment removal component 2 includes multiple ultraviolet lamps 21. Specifically, the multiple ultraviolet lamps 21 can operate simultaneously, or some can operate while others are not. For example, the multiple ultraviolet lamps 21 include a first ultraviolet lamp, a second ultraviolet lamp, and a third ultraviolet lamp. The first and second ultraviolet lamps can be lit simultaneously, the first ultraviolet lamp can be off while the second and third ultraviolet lamps are lit simultaneously, the second ultraviolet lamp can be off while the first and third ultraviolet lamps are lit simultaneously, or all three can be lit simultaneously. In practical applications, the multiple ultraviolet lamps 21 can be reasonably controlled according to the conveyed material or the usage of the conveyor belt 10 to improve the pigment removal effect on the conveyor belt 10 and to allow the ultraviolet lamps to intermittently stop working for heat dissipation, avoiding the impact of continuous operation on their lifespan.

[0030] In some embodiments of this invention, at least some of the multiple ultraviolet lamps 21 can operate alternately, which can improve the service life of the ultraviolet lamps 21. For example, a first part of the multiple ultraviolet lamps 21 can operate first, and another part can start operating after the first part stops operating. Alternatively, a part of the multiple ultraviolet lamps 21 can operate continuously, while the other part operates alternately.

[0031] In some embodiments of this invention, at least a portion of the plurality of ultraviolet lamps 21 are distributed along the rotation direction of the track 10. Thus, as the track 10 rotates and moves within its rotational idle range, the ultraviolet lamps 21 distributed along the rotation direction of the track 10 can continuously remove pigments during the rotation of the track 10. For example, the track 10 has a first position in its rotation direction, where a first ultraviolet lamp is located; and a second position in the same rotation direction, where the track 10 moves from the first position to the second position, where a second ultraviolet lamp is located. In this way, the track 10 is irradiated by the first ultraviolet lamp at the first position, and when the track 10 continues to rotate and move to the second position, the second ultraviolet lamp can continue to irradiate the track 10, thereby extending the irradiation time of the ultraviolet lamps 21 on the track 10 and thus improving the pigment removal effect.

[0032] Optionally, multiple ultraviolet lamps 21 are arranged at intervals along the rotational idle interval to expand the irradiation range. Arranging multiple ultraviolet lamps 21 in the rotational idle interval can improve the decomposition effect of ultraviolet light on the pigments of the track 10. When multiple ultraviolet lamps 21 are turned on simultaneously, the intensity of ultraviolet light can be increased, thereby improving the decomposition effect.

[0033] In some embodiments of this utility model, the color sorter 100 further includes a first controller, which is connected to the ultraviolet lamp 21 and the drive motor of the track 10 for coordinated control of the ultraviolet lamp 21 and the drive motor of the track 10. Thus, the first controller can control the opening and closing of the ultraviolet lamp 21 according to the working state of the drive motor of the track 10. For example, when the track 10 is working, the ultraviolet lamp 21 is turned on synchronously. Since the track 10 begins to transport materials, it is susceptible to material contamination. Therefore, the first controller can control the ultraviolet lamp 21 to turn on according to the opening of the drive motor, allowing the ultraviolet lamp 21 to remove pigments from the track 10 during its rotational idle period. When the drive motor is not driving the track 10, the track 10 is not rotating and is not transporting materials, so there is no contamination problem. Therefore, the first controller can control the ultraviolet lamp 21 to turn off, thereby achieving energy saving and facilitating the automated control of the pigment removal component 2.

[0034] More specifically, the drive motor drives the track 10 to reciprocate between the rotating load section and the rotating idle section. The track 10 is equipped with a drive wheel and a driven wheel, and the track 10 rotates between the drive wheel and the driven wheel. The drive motor can be connected to the drive wheel to drive the track 10 to rotate.

[0035] Combination Figures 1 to 3In some embodiments of this utility model, the pigment removal component 2 further includes a bracket 22, which is stationary relative to the conveying device 1. The ultraviolet lamp 21 is installed inside the bracket 22, and the surface of the bracket 22 facing the track 10 has an opening 201 for the ultraviolet lamp 21 to emit ultraviolet light. In other words, the track 10 moves relative to the bracket 22, while the bracket 22 installed on the ultraviolet lamp 21 can remain stationary, which can improve the stability of the ultraviolet lamp 21 after installation.

[0036] Specifically, bracket 22 can be used to install ultraviolet lamp 21, and the opening 201 of bracket 22 allows the ultraviolet lamp 21 to be installed opposite the rotation idle area, so that ultraviolet light can directly irradiate the conveyor belt 10 located in the rotation idle area, which is beneficial to improving the decomposition effect of pigments. In addition, the opening 201 of bracket 22 can also facilitate the installation of ultraviolet lamp 21. For example, the ultraviolet lamp 21 can be installed on bracket 22 through the opening 201 of bracket 22 first, and then bracket 22 can be installed on bracket 22.

[0037] In some embodiments of this utility model, the distance between the ultraviolet lamp 21 and the track 10 is adjustable. Specifically, the distance between the ultraviolet lamp 21 and the track 10 is adjustable, and the illumination intensity of the ultraviolet lamp 21 can be adjusted according to actual usage needs, thereby adjusting the removal effect of the ultraviolet lamp 21 on the pigments of the track 10.

[0038] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the mounting connectors 2121 at both ends of the ultraviolet lamp 21 are respectively mounted on the bracket 22 and fixed through the waist-shaped hole 202 extending in a direction perpendicular to the track 10, which is used to adjust the distance between the ultraviolet lamp 21 and the track 10 along the waist-shaped hole 202. Specifically, the ultraviolet lamp 21 can extend in the direction of the width of the track 10, which is beneficial to improving the irradiation effect on the track 10. The opposite ends of the ultraviolet lamp 21 are fixedly mounted on the bracket 22, which is beneficial to improving the stability of the ultraviolet lamp 21 after installation. When it is necessary to adjust the distance between the track 10 and the ultraviolet lamp 21, the fixing parts, such as screws, can be loosened, so that the opposite ends of the ultraviolet lamp 21 can move along the extension direction of the waist-shaped hole 202, so that the ultraviolet lamp 21 moves away from or closer to the track 10.

[0039] Optionally, a positioning rib can be constructed within the waist-shaped hole 202, so that during adjustment, the opposite ends of the ultraviolet lamp 21 can be adjusted to the predetermined position simultaneously, which facilitates the improvement of adjustment efficiency and the balance of the ultraviolet lamp 21 after adjustment.

[0040] In some embodiments of this utility model, the color sorter 100 includes a body, a conveying device 1 and a pigment removal component 2, all of which are connected to the body.

[0041] In some embodiments of this utility model, the bracket 22 includes a first positioning part 221 and a second positioning part 222. The first positioning part 221 is connected to the second positioning part 222. The first positioning part 221 is connected to the body of the color sorter 100, and the second positioning part 222 is connected to the ultraviolet lamp 21. The distance between the two first positioning parts 221 is L1, and the distance between the two second positioning parts 222 is L2, wherein L1 > L2. That is to say, the relative sides of the bracket 22 are narrowed inward.

[0042] In this way, the UV lamp 21 is not needed to irradiate the gap between the track 10 and the machine body. The UV lamp 21 can be positioned only relative to the width of the track 10, which helps to improve energy saving. In addition, the waist-shaped hole 202 for adjusting the distance between the UV lamp 21 and the track 10 is provided in the second positioning part 222. The distance difference between the first positioning part 221 and the second positioning part 222 facilitates the adjustment of the position of the UV lamp 21 on the waist-shaped hole 202.

[0043] Combination Figure 5 In some embodiments of this utility model, the second positioning part 222 is provided with a wire hole 204 for connecting the ultraviolet lamp 21 wiring harness and an adjustment hole for connecting the ultraviolet lamp 21. The waist-shaped hole 202 has a third position close to the rotational idle range and a fourth position far away from the rotational idle range. The ultraviolet lamp 21 is movably positioned between the third position and the fourth position.

[0044] In some embodiments of this utility model, the bracket 22 further includes a connecting plate 223 and a base plate 224. The connecting plate 223 is connected between the first positioning part 221 and the second positioning part 222, and the base plate 224 is connected to the end of the second positioning part 222 that is away from the first positioning part 221.

[0045] Specifically, the first positioning part 221 includes a first plate 2211 and a second plate 2212 connected in an "L" shape. The first plate 2211 extends vertically and has positioning holes for fixed connection with the machine body. The second plate 2212 is perpendicular to the first plate 2211 and extends horizontally, and can be used to abut against the machine body or connect or abut against other components of the color sorter 100 to improve the support effect. The second plate 2212 is connected to the connecting plate 223. The connecting plate 223 includes a third plate 2233 and a fourth plate 2234 connected in an "L" shape. The third plate 2233 extends vertically and is connected to the second plate 2212. One end of the fourth plate 2234 is connected to the third plate 2233 and extends horizontally away from the second plate 2212, and the other end is connected to the second positioning part 222.

[0046] Combination Figure 2In some embodiments of this utility model, the bracket 22 is provided with a hollow structure 203 for heat dissipation of the ultraviolet lamp 21. Specifically, the hollow structure 203 is disposed around the ultraviolet lamp 21. The ultraviolet lamp 21 can dissipate heat through the hollow structure 203, which helps to improve operational stability and safety.

[0047] More specifically, the perforated structure 203 is located on the side opposite to the opening 201 of the bracket 22, and the ultraviolet lamp 21 is located between the opening 201 of the bracket 22 and the perforated structure 203. In this way, on the side of the bracket 22 facing the track 10, the ultraviolet lamp 21 can irradiate the track 10 without obstruction, which helps to improve the irradiation effect. On the other side of the bracket 22 away from the track 10, the heat of the ultraviolet lamp 21 during operation can be dissipated outward, avoiding overheating of the ultraviolet lamp 21 inside the bracket 22 and the resulting safety hazard.

[0048] Optionally, a hollow structure 203 can be formed between the base plates 224 on opposite sides of the bracket 22.

[0049] Alternatively, the base plate 224 and the bottom of the bracket 22 can be spaced apart to form a heat dissipation zone.

[0050] Optionally, the intensity of the ultraviolet lamp 21 can also be adjusted by adjusting the current intensity. In some embodiments of this invention, the color sorter 100 further includes a second controller connected to the ultraviolet lamp 21, used to adjust the intensity of ultraviolet light emitted by the ultraviolet lamp 21, thereby realizing automatic adjustment and control of the ultraviolet light intensity of the ultraviolet lamp 21.

[0051] Specifically, the operator can control the intensity of ultraviolet light emitted by the ultraviolet lamp 21 via the second controller according to the actual application. For example, this can be based on the type of material being sorted by the color sorter 100. Alternatively, the color sorter 100 can also include a vision recognition device, which can be positioned opposite the front end of the idle travel section of the rotating conveyor belt 10 to detect the pigment adhesion on the conveyor belt 10, such as pigment depth or pigment area. The vision recognition device can be connected to the second controller, transmitting detection information to it. The second controller can then control the ultraviolet light 21 to emit a preset ultraviolet light intensity based on this detection information.

[0052] The color sorter 100 of this utility model is described below with reference to the accompanying drawings.

[0053] In related technologies, when color sorting chili peppers, the pigments in the chili peppers easily penetrate and stain belts of various materials, severely affecting the recognition performance against the background of the belt. Therefore, this invention proposes a color sorter 100 with a pigment removal component 2, which can remove pigments from the conveyor belt 10, thereby significantly reducing the problem of the conveyor belt 10 being stained by pigments. This improves the accuracy of material sorting by the color sorter 100 and eliminates the need for manual cleaning of the conveyor belt 10.

[0054] Specifically, ultraviolet (UV) light sources are arranged at the bottom of the track 10, in the idle rotation section where no material is being transported. When the track 10 is running, the light sources activate and begin irradiating the belt to prevent it from becoming stained. Theoretically, UV light decomposes capsaicin (carotenoids). The UV light sources can be moved up and down to match appropriate light intensity, and the constant current source can be adjusted to control the light intensity. Multiple UV light sources can be matched to provide effective irradiation based on actual results. The bottom of the UV lamp 21 profile has a hollow structure 203 to facilitate heat dissipation.

[0055] In one embodiment of this utility model, the ultraviolet light wavelength is selected as 365nm (nanometer).

[0056] Alternatively, the track 10 may be made of leather, such as a leather belt.

[0057] Combination Figures 1 to 5 According to the embodiment of the present utility model, the color sorter 100 can be placed on the conveyor belt 10 for dyeing. Specifically, the color sorter 100 includes a conveying device 1 and a pigment removal component 2. The conveying device 1 includes a conveyor belt 10 for conveying materials, and the pigment removal component 2 includes at least one ultraviolet lamp 21 that acts on the rotation idle range of the conveyor belt 10.

[0058] Specifically, ultraviolet light has a photodegradation effect on various pigments, such as anthocyanins (purple cabbage, blueberries, black rice, rose petals, jujube skin, etc.), carotenoids (carrots, tomatoes, corn, peppers, etc.), chlorophyll (green leafy plants), and hemoglobin (various fresh aquatic products). When sorting materials that are easily stained, such as peppers, after the conveyor belt 10 outputs the material, it is irradiated by the ultraviolet lamp 21 in the idle rotation range of the conveyor belt 10 to decompose the pigments. The pigments are decomposed in time, avoiding pigment accumulation, thereby preventing the conveyor belt 10 from changing color and ensuring the sorting and identification performance.

[0059] Specifically, at the front end of the idle travel section of the track 10, multiple ultraviolet lamps 21 can be installed, allowing them to operate alternately to extend their service life. The ultraviolet lamps 21 can be linked to the drive motor of the track 10 for automated control, meaning they can be turned on when the track 10 is in operation. Alternatively, the ultraviolet lamps 21 can also be manually activated by the operator.

[0060] Furthermore, the pigment removal component 2 includes a bracket 22, with an ultraviolet lamp 21 installed inside the bracket 22, and the bracket 22 has an opening 201 facing the surface of the track 10. Thus, the bracket 22 does not block the ultraviolet light from the ultraviolet lamp 21 from irradiating the surface of the track 10, which is beneficial for improving the pigment removal or decomposition effect.

[0061] Furthermore, the distance between the UV lamp 21 and the track 10 is directly adjustable. Specifically, the UV lamp 21 includes a housing 211 and a lamp body 212. Mounting connectors 2121 at both ends of the UV lamp housing 211 are respectively mounted on the brackets 22 at both ends and fixed via oblong holes 202 along the vertical direction. The height of the UV lamp 21 can be adjusted by adjusting its fixed position on the oblong holes 202, thereby adjusting the lighting intensity. The brackets 22 also have wire-passing holes 204 for mounting and positioning the lamp body 212 wiring harness. A perforated structure 203 is constructed at the bottom of the brackets 22 to dissipate heat from the UV lamp 21. Alternatively, a perforated structure 203 can be constructed at the bottom or around the housing 211, for example, by providing heat dissipation holes at the bottom or around the housing to dissipate heat from the lamp body 212.

[0062] Specifically, the housing 211 can be a UV lamp profile used to fix the UV lamp body 211.

[0063] The intensity of ultraviolet light 21 can also be adjusted by adjusting the current intensity.

[0064] The wavelength of the UV lamp 21 can be adjusted between 315nm and 400nm. For example, the wavelength of the UV lamp 21 can be 320nm, 350nm, 365nm, 370nm, 380nm, etc.

[0065] Optionally, multiple ultraviolet lamps 21 can also be configured with different wavelengths, allowing for the selective activation of specific wavelength ultraviolet lamps 21 during practical applications to improve flexibility and enhance the removal effect of pigments from the track 10.
