Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and in particular to a detection and screening device for medicine bottles after filling. Background Technology

[0002] In pharmaceutical manufacturing, tablet filling and capping of vials are critical steps that directly affect the packaging quality and subsequent safety of the medicine. Currently, in pharmaceutical bottle packaging production lines, the number of tablets filled in each vial is standardized. However, in actual production, empty or half-full vials may occur due to filling mechanism malfunctions or untimely material supply. Existing production lines lack effective automatic rejection devices for these non-conforming products, typically relying on manual sampling for inspection. However, manual sampling has significant drawbacks: firstly, it is inefficient and difficult to meet the testing requirements of high-speed production lines; secondly, human judgment is susceptible to fatigue and subjective factors, making it impossible to accurately identify empty or half-full vials, resulting in some non-conforming products flowing into subsequent processes and affecting product quality.

[0003] Meanwhile, in the bottle cap sealing process, issues such as misaligned or loose caps are prone to occur due to factors like cap conveying posture deviations and unstable pressure in the sealing mechanism. Under the current production model, the inspection of bottle cap sealing quality also relies on manual observation, which not only has low accuracy but also fails to achieve full inspection of every bottle of medicine. This further increases the risk of defective products leaving the factory, putting pressure on quality control and potentially damaging the company's market reputation. Utility Model Content

Detailed Implementation

[0014] The following is in conjunction with the appendix Figure 1-2 The principles and features of this utility model are described, making the technical means, creative features, and achieved objectives of this utility model easy to understand, and further elaborating on this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figure 1-2 As shown, a medicine bottle inspection and screening device after filling includes a conveyor belt 1 for conveying medicine bottles that have been sequentially filled with tablets and sealed with caps. A camera 2 and a pneumatic device 3 are sequentially arranged along the conveyor belt 1. A pneumatic device 3 and a collection hood 4 are respectively arranged on both sides of the conveyor belt 1. The pneumatic device 3 includes a first air nozzle 31, a second air nozzle 32, an air source 33, a first solenoid valve 34, a first pressure regulating valve 35, a second solenoid valve 36, and a second pressure regulating valve 37. The first air nozzle 31 and the second air nozzle 32 are both fixed to one side of the conveyor belt 1. The collection hood 4 is connected to the air outlets of the first air nozzle 31 and the second air nozzle 32. The corresponding side is open, and the air inlets of the first air nozzle 31 and the second air nozzle 32 are connected to the air outlet of the air source 33 through pipes. A first solenoid valve 34 and a first pressure regulating valve 35 are sequentially installed on the pipe between the first air nozzle 31 and the air source 33; a second solenoid valve 36 and a second pressure regulating valve 37 are sequentially installed on the pipe between the second air nozzle 32 and the air source 33. The signal output terminal of the camera 2 is connected to the signal input terminal of the controller 38 via a signal connection. The signal output terminal of the controller 38 is connected to the signal input terminals of the first solenoid valve 34, the first pressure regulating valve 35, the second solenoid valve 36, and the second pressure regulating valve 37 via signal connections. The air source 33 uses a GA37 high-pressure air compressor with a rated working pressure of 1.0 MPa. The camera 2 uses an industrial high-definition CCD camera 2 (model MV-CE050-30GM) with a resolution of 2592×1944.

[0018] The blowing pressure of the first air nozzle 31 can be adjusted by the air pressure regulating valve, ranging from 0.2 to 0.5 MPa. For different sizes of medicine bottles such as 50ml and 100ml, the screening accuracy can be ensured by adjusting the pressure. Continuous blowing of air onto the medicine bottles on the conveyor belt 1 will cause full bottles to only experience slight lateral displacement due to their greater weight (including the weight of the tablets and the bottle itself) and they will not fall off the conveyor belt 1. However, empty and half-full bottles, due to their smaller weight, will be blown off the conveyor belt 1 and fall into the collection hood 4, thus achieving the screening of unqualified tablets.

[0019] A buffer pad 5 is fixedly installed on the inner wall corresponding to the opening of the collection cover 4 to prevent the empty or half-empty medicine bottle from being damaged by impact when it enters. A collection box 6 is connected and installed below the collection cover 4.

[0020] The camera 2 is fixed on one side of the conveyor belt 1, and a door-shaped anti-interference cover 7 is provided above the camera 2 and the conveyor belt 1 corresponding to the camera 2.

[0021] Working principle: The pill bottles, after being filled and capped, are conveyed at a constant speed by conveyor belt 1 and first enter the shooting area of ​​camera 2. A gate-shaped anti-interference cover 7 effectively isolates stray light, dust, and airflow interference from the outside, ensuring that camera 2 can clearly capture the cap status of each pill bottle. The captured image information is transmitted to controller 38 in real time. Controller 38 analyzes the received cap images to determine if there are any unqualified sealing issues such as misaligned or loose caps.

[0022] After being detected by camera 2, the medicine bottles continue to be conveyed by conveyor belt 1 and then enter the combined working area of ​​the first air nozzle 31 and the second air nozzle 32 located downstream. During the operation of the device, the first air nozzle 31 is always in a blowing state, and its pressure is adjusted to a preset value by controlling the first pressure regulating valve 35. This causes full bottles to only slightly shift due to their large weight, while empty and half-full bottles are continuously blown away from the conveyor belt 1, fall into the collection hood 4, and enter the collection box 6 below, thus achieving the screening of defective tablets. For full bottles, the controller 38 calls the previously stored bottle cap detection results. If the bottle cap is determined to be defective, a control signal is immediately sent to the second solenoid valve 36 to control it to open quickly, and the pressure is adjusted to a preset value by controlling the second pressure regulating valve 37. The second air nozzle 32 blows air instantaneously to blow the bottle with defective bottle cap into the collection hood 4. If the bottle cap is determined to be acceptable, the medicine bottle continues to be conveyed by conveyor belt 1 to the subsequent process. The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
