Description

Technical Field

[0001] The utility model belongs to the technical field of tablet packaging detection, in particular to a double-sided metal material packaged tablet defect and cavitation light source detector system. Background Art

[0002] With the development of the pharmaceutical market, drug packaging has received more and more attention. Drug packaging mainly consists of three types: bottle packaging, bag packaging, and aluminum-plastic blister packaging. Aluminum-plastic blister packaging is favored by more and more companies and consumers due to its low cost, fast production speed, light weight, easy to carry, and small space occupation. It occupies a large proportion in the pharmaceutical packaging market. Aluminum foil packaging for tablets also has the advantage of protecting drugs. It can prevent drugs from being affected by external factors such as moisture, light, and oxygen, and extend the shelf life and effectiveness of drugs. Since the production of aluminum-plastic blister tablets requires a series of complex assembly line processes such as filling, sealing, and cutting, it is inevitable that drugs will be leaked or broken. Image processing is a powerful tool for tablet detection. Image processing methods, such as image enhancement, image segmentation, image edge extraction, etc., can well achieve the purpose of drug detection. Currently, the common algorithms for detecting tablet integrity on the market can be roughly divided into two categories, traditional algorithms and deep learning algorithms, and both are applied to drugs packaged in single-sided aluminum foil (the integrity of the drug on the other side can be identified by the naked eye). The characteristic of this type of drug is that the images obtained by taking pictures with conventional cameras can be used to realize drug detection.

[0003] Double-sided aluminum foil is often used for drugs that require higher protection performance. Both sides are opaque materials, and the naked eye cannot see the internal tablets, thereby protecting the drugs from the influence of the external environment and ensuring the quality and stability of the drugs. The camera as a data acquisition method will no longer be applicable to drugs packaged in double-sided aluminum foil, and there are certain challenges in judging the integrity of the drugs. The research results in the article Effect of X-ray exposure on the pharmaceutical quality of drug tablets using X-ray inspection equipment (Drug Dev Ind Pharm, vol. 41, no. 6, pp. 953-8, Jun 2015) show that X-ray exposure has no effect on the medicinal properties of drugs, so using X-rays to detect the integrity of double-sided aluminum foil packaged tablets will be a good choice.

[0009] Furthermore, a protective cover is provided on the outside of the conveyor belt, and the light source detector system is arranged inside the protective cover.

[0010] Furthermore, two through holes are symmetrically provided on the side of the protective cover, and the through holes are placed above the conveyor belt.

[0033] Embodiment 1:

[0034] like Figure 1 As shown, the utility model provides a double-sided metal material packaged medicine particle defect and cavitation light source detector system, including a conveyor belt 1 for transmitting medicine plates 5, and a light source detector system 2 and a sorting system 3 are sequentially arranged along the moving direction of the conveyor belt 1. In this embodiment, the light source detector system 2 includes an X-ray source 201 arranged above the conveyor belt 1 and a detector 202 arranged below the conveyor belt 1, the X-ray source 201 and the detector 202 are arranged perpendicular to the axis of the conveyor belt 1, the X-ray source 201 is located within the vertical range of the detector 202, and a waste conveyor belt 6 is arranged below the sorting system 3, and the waste conveyor belt 6 is connected to a waste box 7.

[0035] like Figure 2-Figure 3 As shown, a protective cover 4 is provided on the outside of the conveyor belt 1. The overall shape of the protective cover 4 is a rectangular parallelepiped. Each side panel is made of lead plate. The light source detector system 2 is arranged inside the protective cover 4. Two through holes 401 are symmetrically provided on the side of the protective cover 4. The through holes 401 can accommodate the conveyor belt 1 and the medicine plate 5 on the surface of the conveyor belt to pass through. Although the X-ray measurement used for drug detection is very low, the protective cover 4 is still set to ensure the safety of the detection personnel and the detection environment.

[0036] like Figure 4As shown, the detector 202 is connected to a controller, and the controller is connected to the power component of the sorting system 3. The power component of the sorting system 3 can be a motor or a cylinder structure.

[0037] During detection, the conveyor belt 1 starts running, driving the medicine plate 5 on the surface to move forward and move to the light source detector system 2. The detector 202 collects data of the X-ray light source 201 passing through the medicine plate 5, forms an image and transmits it to the image recognition module. The image recognition module determines whether the tablet is complete. If there is a defect or cavitation, the controller sends a signal to the power component of the sorting system 3, and the power component starts to drive the sorting system 3 to remove the medicine plate 5 from the surface of the conveyor belt.

[0038] Two medicine plates 5 are selected for testing, and the detector 202 collects the scanning data of the imaging of the two test medicine plates, such as Figure 6 As shown, both (a) and (b) can be clearly observed that the same test results can be obtained whether testing from the front side (corresponding to the red side) or the back side (corresponding to the silver side). Among the four loading positions, two positions show circular dark shadows, which are complete tablets, one position shows an arc-shaped shadow, which is a defective tablet, and one position shows a circular bright area, which is a cavitation.

[0039] The above two test panels were tested with traditional algorithms, and the test results are as follows: Figure 7 As shown, it is completely consistent with the detection result of the utility model, and the result shows that it is feasible to use X-ray to detect double-sided aluminum foil medicines.

[0040] Embodiment 2:

[0041] like Figure 5 As shown, the light source detector system 2 also includes a second X-ray source 203 and a second detector 204. The second X-ray source 203 and the second detector 204 are respectively arranged between the X-ray source 201 and the detector 202 and the sorting system 3. The X-ray source 201 and the detector 202 are arranged perpendicular to the axis of the conveyor belt 1. The second X-ray source 203 and the second detector 204 form a certain angle with the axis of the conveyor belt 1, that is, the X-ray source 201 is arranged directly above the axis of the conveyor belt 1, and the second light source 203 is arranged at a position slightly deviated from the axis of the conveyor belt 1. Other technical features are the same as those in Example 1.

[0042] By setting a second X-ray source 203 and a second detector 204, the medicine plate 5 on the surface of the conveyor belt 1 is collected and imaged in the same way as the X-ray source 201 and the detector 202. The second set of X-ray sources is set offset from the axis of the conveyor belt, which can not only verify the detection results to ensure the detection accuracy, but also detect the medicine plate 5 that is offset on the conveyor belt to increase the detection range. The two sets of imaging results are transmitted to the image recognition module, and the image recognition module determines whether the tablet is complete. If there is a defect or cavitation, the controller sends a signal to the power component of the sorting system 3, and the power component starts to drive the sorting system 3 to remove the medicine plate 5 from the surface of the conveyor belt.

[0043] Embodiment 3:

[0044] like Figure 8 As shown, a camera 9, a light source detector system 2 and a sorting system 3 are arranged in sequence above the conveyor belt 1 along its moving direction. The sorting system 3 is connected to a second conveyor belt 8 in the discharging direction, and the second conveyor belt 8 is connected to a finished product box (not shown in the figure); a medicine plate separator (not shown in the figure) simultaneously transports three medicine plates 5 to the upper surface of the conveyor belt 1, and the three medicine plates 5 are dispersed into three different channels through a separation baffle 10 and are transported forward along the conveyor belt 1. The light source detector system 2 includes an X-ray light source 201 and a detector 202. The three medicine plates 5 are all placed within the detection range of the detector 202, and the detector 202 can simultaneously collect image data of the three medicine plates 5; the sorting system 3 includes three independent movable baffles, and the movable baffle is provided with a movable shaft 301 on the side close to the second conveyor belt 8, and the movable shaft 301 is connected to a power component (not shown in the figure).

[0045] like Fig. 9 As shown, the camera 9 and the detector 202 are both connected to the controller, and the controller is connected to the power component of the sorting system 3. The power component of the sorting system 3 can be a motor or a cylinder structure.

[0046] During the inspection, three medicine plates 5 are transported to the conveyor belt 1 at the same time. When passing through the camera 9, the camera 9 collects the surface image of the conveyor belt 1 and transmits it to the controller, which can determine whether the three channels are placed with medicine plates at the same time, thereby accelerating the inspection efficiency; when the medicine plates 5 pass through the light source detector system 2, the detector 202 can detect cavitation or defects in the medicine particles; when the medicine plates 5 pass through the sorting system 3, based on the computer's judgment result on the X-ray acquisition system, it is first determined whether the medicine plates have reached the specified position, and then whether they are qualified tablets. According to the signal transmitted by the controller, if they are qualified drugs, the power device drives the movable shaft 301 to lift the plate upward, and the medicine plate 5 enters the second conveyor belt 8 on the right, and then enters the medicine plate separator, and finally enters the finished product box. Otherwise, the controller sends a signal, and the power device drives the movable shaft 301 to drive the plate downward, and the tablets fall into the waste conveyor belt and enter the waste box.

[0047] The above embodiments describe the present invention in detail, but the above contents are only preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of application of the present invention, such as placing the detector 202 above the conveyor belt 1, placing the X-ray source 201 below the conveyor belt 1, or using 3 or more sets of light source detectors 2, should still fall within the scope of the patent coverage of the present invention.
