DETAILED DESCRIPTION
[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0031] Example 1
[0032] A down classification and detection device includes: a conveying component for conveying down, the conveying component including a connecting tube 10 and a detection tube 13 perpendicular to one end of the connecting tube 10; a collecting component provided with multiple groups and vertically connected and arranged on the detection tube 13; airflow pushers provided on the inner wall of the detection tube 13, and the number and position of the airflow pushers corresponding to the collecting components; a graphic detection component 30 provided on the airflow pushers for collecting down images and judging the down shape based on the collected down images; and a control component for controlling the airflow pushers to eject airflow based on the detection results of the graphic detection component 30, so that the airflow pushes the down into the corresponding collecting component.
[0033] Down is placed in batches into the connecting tube 10, and the down in the connecting tube 10 is blown into the detection tube 13 by airflow, and continues to rise in the detection tube 13. When the down passes through the first collecting component from bottom to top, the corresponding graphic detection component 30 judges the shape of the down. After judgment, if the down meets the morphological characteristics collected by the first collecting component, the control component controls the airflow pusher to spray airflow so that the down is blown into the first collecting component. If the down does not meet the morphological characteristics collected by the first collecting component, the down continues to rise along the detection tube 13 until it finds the collection component with the corresponding morphological characteristics and is collected by the corresponding collection component. The graphic detection component can adopt the mature CDD image detection in the existing technology. Each material form of down has its own growth structure. The morphology of each category is detected by CDD image imaging technology, thereby realizing the classification detection of down.
[0034] In one embodiment, reference Figure 1The conveying assembly also includes a conveying pipe 11 perpendicular to the other end of the connecting pipe 10, and a down feed pipe 12 is vertically connected to the conveying pipe 11. A circulation pipe 14 is provided between the detection pipe 13 and the connecting pipe 10. Down enters the conveying pipe 11 in batches through the down feed pipe 12, and air is introduced into the top of the conveying pipe 11. The down entering the conveying pipe 11 enters the connecting pipe 10 under the action of the airflow and is transported to the detection pipe 13 by the connecting pipe 10. Under the action of the airflow, the down can rise in the detection pipe 13. Due to the floating posture or angle of the down, it is not collected and will rise to the position of the circulation pipe 14. It can re-enter the detection pipe 13 through the circulation pipe 14 and be re-identified. In order to avoid excessive airflow pressure in the detection pipe 13, which causes the down to rise too quickly, an overflow hole is opened on the top of the detection pipe 13 to reduce the airflow pressure circulating in the circulation pipe 14 and ensure the floating speed of the down. The direction of the arrow is the direction of airflow.
[0035] In one embodiment, the collecting assembly includes a collecting tube 41 connected to the detecting tube 13, and the collecting tube 41 is connected to a collecting frame 40 at one end away from the detecting tube 13, and the collecting frame 40 is connected to a down outlet pipe at one end away from the collecting tube 41. The down enters the collecting frame 40 through the collecting tube 41, and is collected centrally by the collecting frame 40. The down inside the collecting frame 40 can be taken out through the down outlet pipe.
[0036] In order to prevent the down in the collection frame 40 from entering the detection tube and affecting the detection effect, refer to Figure 4 and Figure 5 , a barrier is provided in the collection pipe 41, and the barrier includes an annular tube 42 provided on the collection pipe 41, the diameter of the annular tube 42 is larger than the diameter of the collection pipe 41, an arc tube 28 is provided on the top of the inner wall of the annular tube 42, and multiple groups of air outlet holes 281 are provided below the arc tube 28, a branch pipe 23 is provided on the top of the arc tube 28, and the branch pipe 23 is connected to the control component, and the air flow in the arc tube 28 flows out through the air outlet holes 281, and the air flow forms an air curtain in the annular tube 42 to prevent the down in the collection frame 40 from flowing out, and an overflow pipe 43 is provided below the annular tube 42, and the air outlet end of the overflow pipe 43 extends into the collection frame 40. Specifically, when there is no down entering the collection pipe 41, refer to Figure 1The internal airflow of the control component enters the arc tube 28 through the branch pipe 23, and flows out from the air outlet 281 of the arc tube 28 to form an air curtain, which can effectively prevent the down in the collection frame 40 from floating toward the detection tube 13. The air curtain can also prevent the airflow in the detection tube 13 from moving toward the collection tube 41, so that the down enters without passing through the action of the airflow pusher, resulting in the problem of feature collection failure. The gas forming the air curtain finally flows out through the overflow pipe 43 and flows into the collection frame 40, which can dry the down in the collection frame 40 and control the moisture regain of the down.
[0037] In order to prevent the down from being blocked by the air curtain when entering the collection pipe 41, the control component includes a diverter block 22 and an air delivery member arranged on the outer wall of the detection tube 13. Two groups of gas flow channels 221 are provided in the diverter block 22. The ends of the two groups of gas flow channels 221 away from the detection tube 13 are in a connected state, wherein one group of gas flow channels 221 is connected to the airflow pusher, and the other group of gas flow channels 221 is connected to the branch pipe 23. A switching member is provided throughout the diverter block 22, and the switching member controls the air delivery member to switchably connect to one of the two groups of gas flow channels 221. When the corresponding graphic detection component 30 detects the morphological features belonging to the collection component, the switching component moves, and the switching component allows the airflow in the air delivery component to flow into the gas flow channel 221 connected to the airflow pushing component. The airflow pushing component ejects the airflow to blow the down into the collection pipe 41. At this time, no gas enters the branch pipe 23, and the air curtain disappears, making it easier for the down to be blown into the collection frame 40 for collection. When the graphic detection component 30 does not detect the morphological features belonging to the collection component, the switching component does not move, the airflow inside the air delivery component is connected to the branch pipe 23, and no airflow enters the airflow pushing component.
[0038] In one embodiment, the switching member includes a movable plate 24 that is arranged through the diverter block 22, and two groups of through holes 241 are provided on the movable plate 24. An electric push rod 25 is provided on the side wall of the diverter block 22, and the electric push rod 25 is electrically connected to the graphic detection component 30. The electric push rod 25 is fixedly connected to the end of the movable plate 24, and the electric push rod 25 drives the movable plate 24 to move, switches the positions of the two groups of through holes 241, so that one group of through holes 241 is located in the gas flow channel 221, and one group of through holes 241 is sealed in the diverter block 22. When the morphological features detected by the graphic detection component 30 are met, the corresponding electric push rod 25 is started, and the electric push rod 25 drives the movable plate 24 to move, and the positions of the two groups of through holes 241 on the movable plate 24 are changed. Figure 3, so that one group of through holes 241 is located in the gas flow channel 221 connected to the airflow pusher, which facilitates the airflow pusher to spray air so that the down enters the corresponding collection pipe 41, and the other group of through holes 241 is sealed in the diverter block 22, so that no airflow enters the branch pipe 23.
[0039] In one embodiment, reference Figure 2 and Figure 3 The airflow pushing member includes a distribution plate 27 arranged on the inner wall of the detection tube 13. The middle part of one end of the distribution plate 27 away from the inner wall of the detection tube 13 is connected to the graphic detection component 30. The side walls of the distribution plate 27 and both sides of the graphic detection component 30 are connected with air nozzles 26. The distribution plate 27 is connected to one of the groups of gas flow channels 221. Specifically, when the airflow enters the distribution plate 27, the distribution plate 27 diverts the airflow to the two groups of air nozzles 26, so that the air nozzles 26 spray airflow to blow the down into the corresponding collection tubes 41.
[0040] In one embodiment, reference Figure 1 The gas delivery component includes a fan 20 arranged on the outer wall of the connecting pipe 10 and a diverter pipe 21 connected to the multi-component flow block 22. The diverter pipe 21 is connected to the air outlet of the fan 20 through a pipeline. Specifically, the fan 20 draws external gas into the fan 20, and the fan 20 inputs the gas into the diverter pipe 21 through the pipeline. The diverter pipe 21 transports the gas to the multi-component flow block 22.
[0041] Example 2
[0042] The down classification and detection method adopts the down classification and detection device of the first embodiment, and includes the following steps:
[0043] S1: Weigh the down in batches, take a batch of down and place it in the down feeding tube 12, and introduce air into the conveying tube 11. The air flow blows the down along the connecting tube 10 to the detection tube 13, and the down continues to rise in the detection tube 13;
[0044] S2: During the uplift process, the down will pass through different pattern detection components 30 in sequence. The pattern detection components 30 judge the morphological characteristics of the down. When the down meets the morphological characteristics required by the corresponding collection component, the control component controls the airflow pusher to eject airflow, and the airflow pushes the down into the corresponding collection component to complete the collection.
[0045] S3: When the down is not collected during the rising process of the detection tube 13, it enters the circulation tube 14 and re-enters the detection tube 13, and step S2 is repeated.
[0046] Under the action of airflow, the down continues to rise in the detection tube 13. When the down passes through the first collecting component from bottom to top, the corresponding graphic detection component 30 judges the shape of the down. After judgment, if the down meets the morphological characteristics collected by the first collecting component, the control component controls the airflow pusher to spray airflow so that the down is blown into the first collecting component. If the down does not meet the morphological characteristics collected by the first collecting component, the down continues to rise along the detection tube 13, passing through the second collecting component, the third collecting component, and the fourth collecting component until the collection component with the corresponding morphological characteristics is found and collected by the corresponding collection component. If the down cannot be identified due to the floating posture and angle problems of the down during the rising process, when it rises to the height of the circulation pipe 14, it will flow back to the connecting pipe 10 through the circulation pipe 14, and then be transported to the detection center 13 again by the connecting pipe 10.
[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
