Description

Technical Field

[0001] This application relates to the field of packaging defect detection technology, and more specifically, to a device for detecting defects in aluminum foil inner lining paper and frame paper packaging for packaging machines. Background Technology

[0002] Hard-pack packaging equipment is used by major cigarette manufacturers in China. It features a compact design, stable performance, and significant potential for modification. Given the current market demand for irregularly shaped cigarettes, modifying their specifications for subsequent production is a low-investment, high-return approach.

[0003] The patent with authorization announcement number CN209757708U provides a packaging machine aluminum foil liner paper and frame paper packaging defect detection device, which belongs to the field of cigarette packaging machine inspection. The packaging machine aluminum foil liner paper and frame paper packaging defect detection device includes a main forming mold wheel, a mounting bracket, an industrial camera, and an industrial control computer. The mounting bracket is installed on the main forming mold wheel of the packaging machine, the industrial camera is installed on the mounting bracket, the camera of the industrial camera faces the pressing station of the packaging machine, and the output end of the industrial camera is connected to the industrial control computer.

[0004] While the existing technical solutions described above prevent defective cigarette packs with flawed inner frame and lining paper from entering the finished product by using visual imaging detection, these devices can only perform visual inspection on one side of the product. They cannot see through the back of stacked products for comprehensive inspection, making it easy for defective products to be mixed with qualified products. Furthermore, if the product placement interval is not properly controlled during the inspection process, overlapping inspections can easily occur.

[0005] In view of this, we propose a device for detecting defects in aluminum foil inner lining paper and frame paper packaging in packaging machines. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] The purpose of this application is to provide a packaging machine aluminum foil liner paper and frame paper packaging defect detection device, which solves the technical problems of existing packaging defect detection devices that can only perform visual inspection on one side of the product.

In addition, if the product placement interval is not well controlled during the inspection process, it can easily cause overlapping detection. The device realizes double-sided visual inspection and reduces the technical effect of defective products being mixed with qualified products.

[0017] (1) This application is equipped with a flipping component and a rejection component. The product to be inspected is conveyed on the conveyor belt. When it passes through the second vision inspection module, the bidirectional cylinder is started first, which drives the two clamping plates to clamp the product in the center and place it directly below the inspection port. After inspection, the first drive motor starts the rotating rod to rotate, flipping the bidirectional cylinder 180 degrees to flip the product. The back of the product is inspected twice by the first vision inspection module. After the inspection results are analyzed by the controller, if there is any failure in inspection, when passing through the rejection component, the electric push rod is started to drive the rejection plate forward to reject the defective product.

A conveyor belt 111 is rotatably mounted inside the detection table 110. Above the detection table 110, an equidistant feeding component 300, a second visual inspection module 113, a flipping component 200, a first visual inspection module 112, and a rejection component 120 are sequentially arranged. The flipping component 200 is located between the first visual inspection module 112 and the second visual inspection module 113. The flipping component 200 includes a fixed plate 214 fixedly mounted on the conveyor belt 111. A rotating rod 211 is rotatably mounted between the two fixed plates 214. A bidirectional cylinder 212 is located in the middle of the rotating rod 211. A distance sensor is embedded on one side of the bidirectional cylinder 212. Sliding rods on both sides of the bidirectional cylinder 212 are connected to clamping plates 210. A first drive motor 213 is connected to one side of the rotating rod 211. (Reference) Figure 4 The product to be inspected is conveyed on conveyor belt 111. When it passes the second vision inspection module 113, the bidirectional cylinder 212 is activated first, driving the two clamping plates 210 to clamp the product in the center and place it directly below the inspection port. After inspection, the first drive motor 213 starts the rotating rod 211 to rotate. (Reference) Figure 2 The double-acting cylinder 212 is rotated 180 degrees to flip the product, and the back of the product is then subjected to a second visual inspection by the first visual inspection module 112.

[0027] Furthermore, a controller 114 is provided on one side of the first vision detection module 112 and the second vision detection module 113, and a rejection component 120 is provided on one side of the detection table 110. The rejection component 120 is located on the other side of the first vision detection module 112 relative to the flipping component 200. The rejection component 120 includes an electric push rod 121, with an output rod on one side of the electric push rod 121 connected to a rejection plate 122. A guide component 123 is provided on one side of the conveyor belt 111, and the bottom ends of the two guide components 123 are inclined inward. (Reference) Figure 2 After the test results are analyzed by the controller 114, if there is any failure in the test, when passing through the rejection component 120, the electric push rod 121 is activated to drive the rejection plate 122 forward to reject the defective product. The defective product is then guided by the guide component 123 and falls into the placed collection box.

[0028] Furthermore, the equidistant feeding assembly 300 includes a circular frame 312, inside which multiple rotating parts 313 are rotatably arranged. The central shaft of the multiple rotating parts 313 is connected to a second drive motor 311. A feeding groove 310 is opened directly below the bottom of the circular frame 312. The two multiple rotating parts 313 are composed of multiple partitions arranged in annular shape at equal intervals, and the products to be tested can be stored between the two partitions. (Reference) Figure 3The product is placed inside the multi-layer rotating component 313 in advance. The second drive motor 311 starts the multi-layer rotating component 313 to rotate. The rotation speed is controlled, thereby controlling the feeding speed. The product is rotated and discharged from the feeding trough 310 to the conveyor belt 111 for conveying at the same time interval.

[0029] In summary, the packaging defect detection device for aluminum foil inner lining paper and frame paper of the packaging machine disclosed in this application is used in the following way: the product to be inspected is conveyed on the conveyor belt 111. When it passes the second vision detection module 113, the bidirectional cylinder 212 is started first, driving the two clamping plates 210 to clamp the product in the center and place it directly below the detection port. After the detection, the first drive motor 213 starts the rotating rod 211 to rotate, turning the bidirectional cylinder 212 180 degrees to flip the product. The first vision detection module 112 performs a second vision detection on the back of the product. After the detection result is analyzed by the controller 114, if there is any failure in the detection, when it passes the rejection component 120, the electric push rod 121 is started to drive the rejection plate 122 forward to reject the defective product. The defective product falls into the placed collection box by the guide component 123. The product is placed inside the multi-layer rotating component 313 in advance. The second drive motor 311 starts the multi-layer rotating component 313 to rotate. The rotation speed is controlled, thereby controlling the feeding speed. The product is rotated and discharged from the feeding trough 310 to the conveyor belt 111 for conveying at the same time interval.
