Description

Technical Field

[0001] This utility model relates to the field of silkworm cocoon screening technology. More specifically, this utility model relates to a pneumatic rejection device for inferior cocoons. Background Technology

[0002] Traditional sericulture relies primarily on manual labor to peel cocoons one by one from the squares of a cocooning tray. Current mechanical cocoon-picking methods mechanically peel and mix all cocoons from the entire tray, which improves efficiency to some extent. However, this process often mixes thin-skinned cocoons, yellow-spotted cocoons, internally dyed cocoons, and double-cocoons with superior cocoons. Traditional methods are not only time-consuming and labor-intensive, but also inefficient at removing defective cocoons. Furthermore, mechanical cocoon picking easily leads to the mixing of bad and good cocoons, contaminating the superior cocoons with the inferior ones and affecting the quality of the silk.

[0003] With the continuous development of science and technology, a large number of new cocoon-picking equipment have emerged. For the removal of inferior cocoons, the image processing module processes the collected grid cluster images, sends the detected cocoon type and location information to the PLC device, and controls the cocoon-picking mechanism to remove the cocoons with defects.

[0004] Patent publication number CN118002516A discloses a cascaded automatic cocoon picking system. During operation, a grid of cocoons is placed on a conveyor device. The conveyor device moves the grid, and as it passes under an image acquisition device, a loading and photographing module captures images of the grid and cocoons. An image processing module then obtains the position and category information of the good and bad cocoons and transmits this information to a screening device. When the grid moves under the NG and OK cocoon picking mechanisms, the picking mechanisms sequentially remove the good and bad cocoons from the grid for collection based on the position and category information. The NG cocoon picking mechanism uses a servo KK module to move a top cocoon cylinder to the position corresponding to the bad cocoons above the grid for removal. However, this device has a high cost for the servo KK module, limited overload capacity, a heavy picking mechanism, and is prone to overheating and damage to the servo motor during continuous operation. Furthermore, its complex structure makes repair difficult in case of malfunction. The use of a servo KK module... The module requires extremely high precision in motion control during the cocoon-picking process. Long-term operation will cause structural components to wear and age, and the decrease in positioning accuracy will lead to damage to the grid clusters. Utility Model Content

[0005] One object of this invention is to solve the above-mentioned problems and / or defects, and to provide the advantages that will be described later.

[0006] To achieve these objectives and other advantages of this utility model, a pneumatic defective cocoon removal device is provided, comprising: a photographing module for capturing images of square clusters, an image processing module for identifying defective cocoons in the images, a defective cocoon removal mechanism for removing defective cocoons from square clusters, and a control module electrically connected to the image processing module to control the operation of the defective cocoon removal mechanism. The defective cocoon removal mechanism includes: a frame, a transmission mechanism mounted on the frame for moving square clusters, and a pneumatic removal platform fixed to the frame.

[0007] Multiple top cocoon cylinders are set on the pneumatic rejection platform and arranged in an array;

[0008] Multiple blocking cylinders are fixed to the output side below the transmission mechanism and arranged at predetermined distances.

[0009] Multiple infrared positioning sensors are fixed on the frame and configured to cooperate with each blocking cylinder;

[0010] Multiple sets of positioning cylinders are arranged in pairs on one side of the frame and cooperate with each blocking cylinder to fix the grid cluster.

[0011] The distance between two adjacent blocking cylinders and the distance between two adjacent positioning cylinder groups are both the width of the array formed by the top cocoon cylinders.

[0012] Preferably, the inferior cocoon removal mechanism further includes: a linear scraper disposed at a corresponding position on the pneumatic removal platform below the transmission mechanism to separate residual floating silk;

[0013] A drive motor fixed inside the frame to drive the linear scraper to rotate.

[0014] Preferably, the frame has a rotating shaft on the side opposite to the drive motor;

[0015] The drive motor's power output end and the end of the shaft near the drive motor are both equipped with turntables.

[0016] The linear scraper is configured as two blades, symmetrically arranged between the two turntables with respect to the turntable axis.

[0017] Preferably, the inferior cocoon removal mechanism further includes: a top cocoon head fixing sheet metal part disposed below the pneumatic removal platform;

[0018] The top cocoon head fixing sheet metal part is configured in a U-shape and has multiple square holes for the top cocoon heads of each top cocoon cylinder to pass through.

[0019] This utility model has at least the following beneficial effects: by setting a fixed pneumatic rejection platform, the square cluster is moved by a transmission mechanism, and the square cluster is fixed at each rejection position by only multiple blocking cylinders, infrared positioning sensors, and positioning cylinders, thereby completing the rejection of inferior cocoons. Compared with the servo module driving the top cocoon cylinder to move, it has lower cost, simpler structure and lower maintenance difficulty, is less prone to failure and damage under continuous operation, has better positioning accuracy, and is less likely to be damaged by wear of structural components; and while ensuring work efficiency, it can greatly reduce manufacturing and maintenance costs, which is conducive to the promotion and popularization of the device.

[0035] Example 1

[0036] A pneumatic device for removing inferior cocoons, the structure of which is as follows: Figure 1-6 As shown, it includes: a photo-taking module for capturing images of the grid cluster 2, an image processing module for identifying defective cocoons in the images, a defective cocoon removal mechanism for removing defective cocoons from the grid cluster 2, and a control module electrically connected to the image processing module to control the operation of the defective cocoon removal mechanism. The defective cocoon removal mechanism includes: a frame 1, a transmission mechanism mounted on the frame 1 for moving the grid cluster 2, and a pneumatic removal platform fixed to the frame 1.

[0037] Multiple cocoon-top cylinders 5 are set on the pneumatic rejection platform and arranged in an array;

[0038] Multiple blocking cylinders 13 are fixed on the output side below the transmission mechanism and arranged at predetermined distances;

[0039] Multiple infrared positioning sensors 16 are fixed on the frame 1 and are configured to cooperate with each blocking cylinder 13;

[0040] Multiple sets of positioning cylinder groups 14 are arranged in pairs on one side of the frame 1 and cooperate with each blocking cylinder 13 to fix the grid cluster 2.

[0041] The distance between two adjacent blocking cylinders 13 and the distance between two adjacent positioning cylinder groups 14 are both the width of the array formed by the top cocoon cylinders 5.

[0042] In practical applications, two support frames 3 are provided opposite each other on the outer side of the frame 1. A longitudinal sheet metal part 4 is provided between the two support frames 3 to connect the two support frames 3 as a pneumatic rejection platform. The square hole structure of the square cluster 2 is arranged in 18 rows and 9 columns. The pneumatic rejection platform has 3 rows and 9 columns of cocoon-topping cylinders 5 corresponding to the positions of the square holes of the square cluster 2. The cocoon-topping head 6 is installed at the end of the cocoon-topping cylinder 5. The cocoon-topping head 6 has a concave design, and its length and width are slightly smaller than the size of the squares in the square cluster 2 to prevent friction with the edges of the square holes in the square cluster 2. Its edges are similar to Similar to a cutting blade design, it can effectively separate the floating silk from the square cluster 2 of the cocoon; each top cocoon cylinder 5 is equipped with an electromagnetic valve island 21 at its top, and the control air pipe of each top cocoon cylinder 5 is connected to the electromagnetic valve in the top electromagnetic valve island 21. The control bus of the electromagnetic valve island 21 is connected to the control module for communication; the transmission mechanism includes: a transmission motor 11 set on the frame 1, a drive shaft 9 driven by the transmission motor 11, a driven shaft 10 set at the entrance of the frame 1 and driven by the drive shaft 9 via a synchronous belt 12, and a driven shaft 10 set on the frame 1. The support shaft 7 at the outlet connects to the driven shaft 10 and a pair of oppositely arranged conveyor belts for placing the square cluster 2; a cocoon dropping funnel 17 is provided inside the frame 1 at a position corresponding to the pneumatic rejection platform, through which rejected inferior cocoons are collected; the positioning cylinders are all fixed at the outer side opening on one side of the frame 1; the frame 1 has six evenly arranged support beams 15 between the two conveyor belts, and a blocking cylinder 13 is provided at the center of each support beam 15, which is located at a distance from the pneumatic rejection platform. The distances from near to far are from the first blocking cylinder 13 to the sixth blocking cylinder 13, with a spacing equal to the distance between the three rows of squares in the square cluster 2. Each infrared positioning sensor 16 is installed on the side of each blocking cylinder 13 on the support beam 15, corresponding to the first infrared positioning sensor 16 to the sixth infrared positioning sensor 16. When the positioning cylinder group 14 is fixed, a pair of positioning cylinder groups 14 respectively fixes the protruding parts at the front and rear ends of the same side of the square cluster 2, so that the other side of the square cluster 2 abuts against the support frame 3 for fixation. There are six groups of positioning cylinder groups 14, each group's installation position corresponding to the front and rear positions of the square cluster 2 blocked by each blocking cylinder 13, namely the first positioning cylinder group 14 to the sixth positioning cylinder group 14.

[0043] Working principle: During operation, the square cluster 2 is automatically fed into the inferior cocoon removal area via the conveyor belt 8. At this time, the first to sixth blocking cylinders 13 are in a blocking state, and the matrix signal of the inferior cocoon coordinates has been transmitted to the control module. Then, the infrared positioning sensor 16 detects that the square cluster 2 has reached the position of the blocking cylinder 13, the conveyor motor stops rotating, and the first positioning cylinder group 14 located on the side extends to fix the square cluster 2, entering the inferior cocoon removal mode. At this time, the pneumatic removal platform is precisely aligned with the first three rows of square cluster 2. The top cocoon cylinder 5 corresponding to the first three rows of inferior cocoon positions extends to drive the top cocoon head 6 to remove the inferior cocoon. The inferior cocoon falls into the cocoon dropping funnel 17 for collection. The top cocoon cylinder 5 retracts, and the side positioning cylinder group 14 retracts. The first blocking cylinder 13 retracts, completing the removal of the first three rows. Then, the control module controls the conveyor motor to rotate, moving the grid cluster 2 to the position of the second blocking cylinder 13. At this time, the fourth to sixth rows of grid cluster 2 are aligned with the pneumatic removal platform, and the removal action is performed. This process is repeated until all inferior cocoons in the entire grid cluster 2 are removed. When all inferior cocoons are removed, the sixth positioning cylinder group 14 retracts, and the corresponding blocking cylinder 13 retracts and enters the release state. The conveyor motor starts, and the conveyor belt 8 drives the grid cluster 2 out of the removal area. When the sixth infrared positioning sensor 16 detects that the grid cluster 2 has completely exited the removal area, all the first to sixth level blocking cylinders 13 extend, waiting for the next grid cluster 2 to enter the removal area.

[0044] By setting up a fixed pneumatic rejection platform, the grid cluster 2 is moved by a transmission mechanism. The grid cluster 2 is fixed at each rejection position by multiple blocking cylinders 13, infrared positioning sensors 16, and positioning cylinders, thereby completing the rejection of inferior cocoons. Compared with the servo module moving the top cocoon cylinder 5, this device has low cost, simple structure, and lower maintenance difficulty. It is not prone to failure or damage under continuous operation, and the positioning accuracy is more guaranteed. It is not easy for the grid cluster to be damaged due to wear of structural parts. Moreover, while ensuring work efficiency, it can greatly reduce manufacturing and maintenance costs, which is conducive to the promotion and popularization of the device.

[0045] Example 2

[0047] A drive motor 18 is fixed inside the frame 1 and drives the linear scraper 19 to rotate.

[0048] The frame 1 is provided with a rotating shaft on the side opposite to the drive motor 18;

[0049] The drive motor 18 has a turntable at both its power output end and the end of its shaft near the drive motor 18.

[0050] The linear scraper 19 is configured as two, symmetrically arranged between the two turntables with respect to the axis of the turntable.

[0051] Working principle: When the square cluster 2 moves to the pneumatic removal platform to remove inferior cocoons, the drive motor 18 drives the linear scraper 19 to rotate through the turntable during the movement of the square cluster 2. This scrapes off the residual floating silk hanging below the square cluster 2 and separates it from the cocoon, allowing the cocoon to fall smoothly into the cocoon dropping funnel 17, so as to avoid the square cluster 2 getting stuck during the movement.

[0054] The top cocoon head fixing sheet metal part 20 is configured in the shape of a U, and has multiple square holes for the top cocoon head 6 of each top cocoon cylinder 5 to pass through.

[0055] Working principle: The top cocoon head fixing sheet metal part 20 is set to keep the position and direction of the top cocoon head 6 always corresponding to the position of the three rows of squares in the square cluster 2, so as to avoid the position or direction of the top cocoon head 6 shifting during operation and causing damage to the square cluster 2.
