Description
技术领域 technical field
本发明涉及色选机领域，具体涉及一种带式色选机。 The invention relates to the field of color sorters, in particular to a belt-type color sorter.
背景技术 Background technique
目前，带式色选机已广泛应用于粮食、塑料、矿石等行业，特别是在矿石颗粒等加工流水生产线生产过程中，其高效优势尤为明显。 At present, the belt color sorter has been widely used in grain, plastic, ore and other industries, especially in the production process of ore particle processing production line, its high efficiency advantage is particularly obvious.
带式色选机的工作原理是，通过振动入料斗将物料均匀分布到输送带上，物料在输送带上以较高的速度运行，在离开输送带后，由于惯性的作用，以抛物线轨迹自由下落，在物料从图像采集镜头和背景板中间经过时，图像采集镜头对物料进行图像采集，物料判别系统对物料的颜色进行判别。当物料为剔除物时，空气吹嘴按照控制指令，将剔除物吹下，剔除物经空气吹嘴吹下后改变原来运动轨迹，继续下落，部分剔除物会落在光学玻璃上，并停留在光学玻璃上，这样落在光学玻璃上的物料会阻挡图像采集镜头的视线从而影响识别系统的判断，造成误判和空气吹嘴的误吹，直接影响色选机的色选精度。 The working principle of the belt color sorter is that the material is evenly distributed on the conveyor belt by vibrating into the hopper, and the material runs at a high speed on the conveyor belt. When the material passes between the image acquisition lens and the background plate, the image acquisition lens collects the image of the material, and the material discrimination system discriminates the color of the material. When the material is rejects, the air nozzle blows down the rejects according to the control instructions. After the rejects are blown down by the air nozzle, they change their original trajectory and continue to fall. Part of the rejects will fall on the optical glass and stay on the On the optical glass, the material falling on the optical glass will block the line of sight of the image acquisition lens and affect the judgment of the recognition system, resulting in misjudgment and false blowing of the air nozzle, which directly affects the color sorting accuracy of the color sorter.
目前，为了解决带式色选机光学玻璃的不清洁问题，主要采用以下几种方法：一是加装橡胶刮尘刷，但对于矿石物料，其中的沙尘落在光学玻璃上时，刮尘刷的运动摩擦会使光学玻璃产生伤痕而影响色选精度；二是采用吹风的方式把玻璃表面的尘沙吹走，该方法虽然对去除色选机光学玻璃表面的尘沙粘附有改善，但不能根本解决问题；三是采用清水清洗或水浴玻璃滚筒的方法，该方法存在的问题是带水工作因水帘不可能是平整的，所以影响色选精度，且水干后光学玻璃表面挂花现象不易消除，也影响色选精度；同时因为色选机是连续工作的，所以清洗干燥的时间间隔有限。 At present, in order to solve the dirty problem of the optical glass of the belt color sorter, the following methods are mainly adopted: one is to install a rubber dust scraping brush, but for ore materials, when the sand and dust fall on the optical glass, the scraping dust The movement friction of the brush will cause scars on the optical glass and affect the color sorting accuracy; the second is to blow away the dust and sand on the glass surface by blowing. Although this method can improve the removal of dust and sand on the optical glass surface of the color sorter, But it can't solve the problem fundamentally; the third is to use the method of cleaning with water or bathing the glass roller. The problem with this method is that the work with water can not be flat because the water curtain cannot be flat, so it affects the accuracy of color selection, and the surface of the optical glass is stained after the water dries. The phenomenon is not easy to eliminate, and also affects the accuracy of color sorting; at the same time, because the color sorter works continuously, the time interval for cleaning and drying is limited.

下面结合附图对本发明做进一步说明： The present invention will be further described below in conjunction with accompanying drawing:
实施例1：如图1所示的一种带式色选机，包括用于输送物料且呈上下方向布置的第一输送带1，第一输送带1的出料端上方设有用于采集物料图像信息的上箱体3，上箱体3内设有图像采集镜头31及光源32；第一输送带1的出料端下方设有下箱体4，下箱体4内设有与图像采集镜头31相对应的背景板41及背景板光源42，第一输送带1的出料端还分别设有空气吹嘴5及接料斗，第一输送带1由振动入料斗6给料，下箱体4的箱口处设有密封下箱体4的光学玻璃43，光学玻璃43与水平面之间的夹角为65°～115°。 Embodiment 1: a kind of belt type color sorter as shown in Figure 1, comprises the first conveyer belt 1 that is used for conveying material and is arranged in the up and down direction, is provided with above the discharge end of the first conveyer belt 1 and is used for collecting material The upper casing 3 of the image information, the upper casing 3 is provided with an image acquisition lens 31 and a light source 32; The background plate 41 and the background plate light source 42 corresponding to the lens 31, the discharge end of the first conveyor belt 1 is also provided with an air blowing nozzle 5 and a hopper respectively, the first conveyor belt 1 is fed by a vibrating hopper 6, and the lower box The box opening of the body 4 is provided with an optical glass 43 that seals the lower box 4, and the angle between the optical glass 43 and the horizontal plane is 65° to 115°.
在第一输送带1的下方还设置有第二输送带2，第二输送带2的出料端上方设有用于采集物料图像信息的上箱体3，上箱体3内设有图像采集镜头31及光源32；第二输送带2的出料端下方设有下箱体4，下箱体4内设有与图像采集镜头31相对应的背景板41及背景板光源42，第二输送带2的出料端还设有空气吹嘴5及接料斗，第二输送带2由第一输送带1出料端的接料斗给料，下箱体4的箱口处设有密封下箱体4的光学玻璃43，光学玻璃43与水平面之间的夹角为65°～115°。 A second conveyor belt 2 is also arranged below the first conveyor belt 1, an upper box 3 for collecting material image information is arranged above the discharge end of the second conveyor belt 2, and an image acquisition lens is arranged in the upper box 3 31 and a light source 32; the lower box 4 is provided below the discharge end of the second conveyor belt 2, and a background plate 41 and a background plate light source 42 corresponding to the image acquisition lens 31 are provided in the lower box 4, and the second conveyor belt The discharge end of 2 is also provided with an air blow nozzle 5 and a hopper, the second conveyor belt 2 is fed by the hopper at the discharge end of the first conveyor belt 1, and the box mouth of the lower box 4 is provided with a sealed lower box 4 The optical glass 43, the angle between the optical glass 43 and the horizontal plane is 65°-115°.
优选的光学玻璃（43）与水平面之间的夹角为80°。也就是光学玻璃43与水平面之间的夹角α接近于垂直角度，这样物料的剔除物在被吹下时，个别物料或尘土即便是与光学玻璃相接触，也会因重力的作用不会停留在光学玻璃43上，可以保证光学玻璃43处于洁净的状态，消除了图像采集镜头的视觉障碍，提高了色选精度。做为更为优选的方案，可以在光学玻璃43上附加刮尘刷进行定期清洁，还可以在光学玻璃43上附加空气吹帘吹风，这样光学玻璃43的清洁效果会更好。光学玻璃43的形状可以是平板状的，也可以是弧形或其他形状的，且光学玻璃43也可以采用其他透明材料替换。 The preferred angle between the optical glass (43) and the horizontal plane is 80°. That is, the angle α between the optical glass 43 and the horizontal plane is close to the vertical angle, so that when the rejects of the material are blown down, individual materials or dust will not stay due to the effect of gravity even if they are in contact with the optical glass. On the optical glass 43, it can be ensured that the optical glass 43 is in a clean state, which eliminates the visual obstacle of the image acquisition lens and improves the color selection accuracy. As a more preferred solution, a duster brush can be added to the optical glass 43 for regular cleaning, and an air curtain can also be added to the optical glass 43 to blow air, so that the cleaning effect of the optical glass 43 will be better. The shape of the optical glass 43 can be flat, also can be curved or other shapes, and the optical glass 43 can also be replaced by other transparent materials.
进一步的，第一输送带1及第二输送带2的角度可调，且第一输送带1及第二输送带2与水平面之间夹角的最大值应小于物料的运动运动安息角。也就是第一输送带1及第二输送带2可以根据物料的不同选择不同的角度，第一输送带1及第二输送带2不一定处于水平位置。由于物料的比重不同，所以物料从第一输送带1及第二输送带2的出料端自由抛落的轨迹也不同，为了保证物料的自由抛落轨迹始终处于图像采集镜头的最佳辩识位置，可以根据物料的比重调整第一输送带1及第二输送带2的角度，但需要注意的是，第一输送带1及第二输送带2与水平面之间夹角的最大值应小于物料的运动运动安息角。 Further, the angles of the first conveyor belt 1 and the second conveyor belt 2 are adjustable, and the maximum value of the angle between the first conveyor belt 1 and the second conveyor belt 2 and the horizontal plane should be smaller than the angle of repose of the movement of the material. That is, the first conveyor belt 1 and the second conveyor belt 2 can choose different angles according to different materials, and the first conveyor belt 1 and the second conveyor belt 2 are not necessarily in a horizontal position. Due to the different specific gravity of materials, the trajectories of free throwing of materials from the discharge end of the first conveyor belt 1 and the second conveyor belt 2 are also different. In order to ensure that the free throwing trajectories of materials are always in the best identification of the image acquisition lens position, the angle of the first conveyor belt 1 and the second conveyor belt 2 can be adjusted according to the specific gravity of the material, but it should be noted that the maximum angle between the first conveyor belt 1 and the second conveyor belt 2 and the horizontal plane should be less than The movement of the material moves the angle of repose.
进一步的，接料斗包括设置在第一输送带1出料端的第一接料斗11及第二接料斗12，还包括设置在第二输送带2出料端的第三接料斗21及第四接料斗22，物料由第一输送带1的出料端自由抛落至第一接料斗11或由空气吹嘴5吹入第二接料斗12以实现一级分选，落入第一接料斗11或第二接料斗12内的物料继续落至第二输送带2上，物料由第二输送带2的出料端自由抛落至第三接料斗21或由空气吹嘴5吹入第四接料斗22以实现二级分选。换句话说，本发明相当于沿上下方向设置了两组分选机构，以提高物料的分选精度，在实际使用中，可根据物料的实际需求情况设置单组或连续多组的分选机构。 Further, the receiving hopper includes the first receiving hopper 11 and the second receiving hopper 12 arranged at the discharge end of the first conveyor belt 1, and also includes the third receiving hopper 21 and the fourth receiving hopper arranged at the discharging end of the second conveyor belt 2 22. The material is freely thrown from the discharge end of the first conveyor belt 1 to the first receiving hopper 11 or blown into the second receiving hopper 12 by the air blowing nozzle 5 to realize primary sorting, and falls into the first receiving hopper 11 or The material in the second receiving hopper 12 continues to fall onto the second conveyor belt 2, and the material is freely thrown from the discharge end of the second conveyor belt 2 to the third receiving hopper 21 or blown into the fourth receiving hopper by the air blowing nozzle 5 22 to achieve secondary sorting. In other words, the present invention is equivalent to setting up two sets of sorting mechanisms along the up and down directions to improve the sorting accuracy of materials. In actual use, a single set or continuous multiple sets of sorting mechanisms can be set according to the actual demand of materials. .
进一步的，第一输送带1、第二输送带2、上箱体3、下箱体4、空气吹嘴5、振动入料斗6及接料斗分别设置在机架上。 Further, the first conveyor belt 1, the second conveyor belt 2, the upper box body 3, the lower box body 4, the air blow nozzle 5, the vibrating feeding hopper 6 and the receiving hopper are respectively arranged on the frame.
进一步的，第一输送带1与第二输送带2的输送方向相反。 Further, the conveying direction of the first conveyor belt 1 and the second conveyor belt 2 are opposite.
本发明的工作原理是： The working principle of the present invention is:
工作时，物料先从振动入料斗的出口落至第一输送带上，物料自第一输送带的出料端因惯性作用自由抛落，在物料经过图像采集镜头和背景板中间时，图像采集镜头对物料进行图像采集，物料辩别系统对物料的颜色进行辩识。当物料为非剔除物时，空气吹嘴不动作，物料仍然按原有的抛物线轨迹下落，落入第一接料斗；当物料为剔除物时，空气吹嘴按照控制指令，将剔除物吹下，剔除物经空气吹嘴喷吹后改变原来的运动轨迹，进入第二接料斗，这是对物料的第一次分选；进入第一接料斗或第二接料斗内的物料继续下落至第二输送带，物料自第二输送带的出料端因惯性作用自由抛落，在物料经过图像采集镜头和背景板中间时，图像采集镜头对物料进行图像采集，物料辩别系统对物料的颜色进行辩识。当物料为非剔除物时，空气吹嘴不动作，物料仍然按原有的抛物线轨迹下落，落入第三接料斗；当物料为剔除物时，空气吹嘴按照控制指令，将剔除物吹下，剔除物经空气吹嘴喷吹后改变原来的运动轨迹，进入第四接料斗，这是对第一接料斗或第二接料斗内物料的进一步分选。在剔除物被吹下时，个别物料或尘土即便与光学玻璃相接触，由于重力作用也不会停留在光学玻璃上，光学玻璃可以始终处于一个洁净的状态，可以消除图像采集镜头的视觉障碍，提高色选精度。 When working, the material first falls from the outlet of the vibrating hopper to the first conveyor belt, and the material is thrown freely from the discharge end of the first conveyor belt due to inertia. When the material passes through the middle of the image acquisition lens and the background plate, the image acquisition The lens collects the image of the material, and the material identification system identifies the color of the material. When the material is non-rejection, the air nozzle does not operate, and the material still falls according to the original parabolic trajectory, and falls into the first hopper; when the material is rejection, the air nozzle blows down the rejection according to the control command After being blown by the air nozzle, the rejects change their original trajectory and enter the second receiving hopper, which is the first sorting of materials; the materials entering the first receiving hopper or the second receiving hopper continue to fall to the second receiving hopper The second conveyor belt, the material is thrown freely from the discharge end of the second conveyor belt due to inertia. When the material passes between the image acquisition lens and the background plate, the image acquisition lens collects the image of the material, and the material identification system determines the color of the material. Identify. When the material is non-rejection, the air nozzle does not move, and the material still falls according to the original parabolic trajectory, and falls into the third hopper; when the material is rejection, the air nozzle blows down the rejection according to the control command After being blown by the air nozzle, the rejects change their original trajectory and enter the fourth receiving hopper, which is a further sorting of the materials in the first receiving hopper or the second receiving hopper. When the rejects are blown down, even if individual materials or dust are in contact with the optical glass, they will not stay on the optical glass due to gravity, and the optical glass can always be in a clean state, which can eliminate the visual barrier of the image acquisition lens, Improve color sorting accuracy.
