Description

Technical Field

[0001] This utility model relates to the field of powder-liquid dual-chamber bag production technology, and in particular to a powder-liquid dual-chamber bag light inspection system. Background Technology

[0002] The powder-liquid dual-chamber bag is a ready-to-use infusion product. The bag body is made of a transparent co-extruded film. The product consists of two parts: a liquid chamber containing the injectable solvent and a powder chamber containing the drug powder. The two chambers are separated by a weakly welded partition. During use, medical personnel simply squeeze the liquid chamber to open the weakly welded partition, allowing the injectable solvent in the liquid chamber and the drug powder in the powder chamber to mix thoroughly before use.

[0003] The production area for powder-liquid dual-chamber bags includes a liquid production area and a powder-liquid mixing production area. After the liquid raw material is filled into the liquid chamber in the liquid production area, the bag is transferred to the powder-liquid mixing production area. After being filled with powder raw material by the powder filling machine, both the liquid and powder chambers undergo a light inspection process. Only bags that pass inspection can proceed to the next process, where they are processed by an aluminum foil welding machine.

[0004] However, in the existing light inspection process, the operator simply holds the powder-liquid double-chamber bag and visually inspects the powder chamber to remove any bags containing foreign objects. This inspection method requires the operator to lift each powder-liquid double-chamber bag individually, and because foreign objects come in a variety of colors, those that are similar in color to the powder raw material inside the powder chamber are difficult to detect. Therefore, this light inspection method needs improvement. Utility Model Content

[0005] To address the problems existing in the current technology, namely the low inspection efficiency and difficulty in removing foreign objects of different colors, this utility model aims to provide a powder-liquid dual-chamber bag light inspection system. This system automates the transmission of the entire powder-liquid dual-chamber bag, performing a single light inspection on each of the powder and liquid chambers. Different colored background boards assist operators in their inspection, ensuring that foreign objects of different colors are exposed under the background boards with significant color differences, making it easier for operators to spot them. This system boasts advantages such as simple structure and high automation, effectively removing foreign objects and ensuring a high product qualification rate.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A powder-liquid dual-chamber bag light inspection system includes a light inspection annular belt and a powder chamber inspection mechanism. The powder chamber inspection mechanism is used to inspect the powder chamber of the powder-liquid dual-chamber bag. The powder chamber inspection mechanism includes a plane mirror, an adjustable light source, and two or more powder chamber background plates. Each powder chamber background plate has a single color, and all powder chamber background plates have different colors. The light inspection annular belt conveys the powder-liquid dual-chamber bag through all the powder chamber background plates in sequence. The powder chamber background plates are used to create a color difference with foreign objects to assist in the manual detection of foreign objects. The adjustable light source is used to provide a light source, and the plane mirror is used to observe the rear side of the powder-liquid dual-chamber bag.

[0008] The present invention is further configured such that: the powder cavity inspection mechanism also includes a powder cavity vibrator, and a powder cavity vibrator is correspondingly provided in front of each powder cavity background plate.

[0009] The present invention is further configured such that: the light inspection ring belt is provided with a clamping station for fixing the powder liquid double chamber bag, each powder chamber background plate covers at least three adjacent clamping stations and the powder chamber vibrator is located at the middle position of the three adjacent clamping stations.

[0010] The present invention is further configured such that the color of the powder cavity background plate includes at least one color from the dark color family and one color from the light color family.

[0011] The present invention is further configured such that: the powder cavity inspection mechanism is provided with two powder cavity background plates, the colors of the two powder cavity background plates being black and white, respectively.

[0012] The present invention is further configured to include a liquid chamber inspection mechanism, which is used to inspect the liquid chamber of the powder-liquid dual-chamber bag.

[0013] The present invention is further configured such that: the liquid cavity inspection mechanism is provided with a plane mirror, an adjustable lamp, and two or more liquid cavity background plates, each of the liquid cavity background plates is of a single color and all the liquid cavity background plates are of different colors, the lamp inspection annular belt conveys the powder liquid double chamber bag into the liquid cavity inspection mechanism and passes through all the liquid cavity background plates in sequence, the liquid cavity background plates are used to form a color difference with the foreign object to assist in the manual detection of the foreign object.

[0014] The present invention is further configured to include a visual inspection mechanism, which is used to inspect the overall shape of the powder-liquid dual-chamber bag.

[0015] The present invention is further configured such that the light inspection annular belt conveys the powder liquid double-chamber bag into the appearance inspection mechanism.

[0016] The present invention is further configured such that the appearance inspection mechanism is located upstream of the powder cavity inspection mechanism and the liquid cavity inspection mechanism.

[0017] In summary, the beneficial effects achieved by this utility model are as follows:

[0018] (1) The double-chamber bag of powder and liquid to be inspected is conveyed by the light inspection ring belt, which not only improves the level of automation and eliminates the inefficient operation of manually lifting the double-chamber bag of powder and liquid one by one, but also avoids the influence of personnel on the product during the production process and ensures the quality of the double-chamber bag of powder and liquid.

[0019] (2) The powder and liquid double chamber bag to be inspected is inspected by the appearance inspection mechanism, the powder chamber inspection mechanism and the liquid chamber inspection mechanism, so that the overall shape of the powder and liquid double chamber bag and the powder chamber and the liquid chamber are inspected by light once in turn, which improves the detection effect of the light inspection process.

[0020] (3) Use background boards of different colors to create color differences with foreign objects, assist operators in inspection, so that foreign objects of different colors can be exposed under the background board with a large color difference, making it easier for operators to find foreign objects, thereby effectively removing foreign objects and ensuring product qualification rate.

[0021] (4) The powder chamber vibrator installed in the powder chamber inspection mechanism, together with the powder chamber background plate, can perform two inspections on the powder chamber of the powder-liquid double chamber bag before and after vibration, thereby detecting foreign objects that are not easy to be found in the powder raw materials and ensuring the quality of the powder-liquid double chamber bag products.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] As attached Figure 1 and attached Figure 2 As shown, a powder-liquid dual-chamber bag light inspection system includes a light inspection annular belt 2, a visual inspection mechanism 3, a powder chamber inspection mechanism 4, and a liquid chamber inspection mechanism 5. The light inspection annular belt 2 is used to transport the powder-liquid dual-chamber bag 1 sequentially through the visual inspection mechanism 3, the powder chamber inspection mechanism 4, and the liquid chamber inspection mechanism 5.

[0033] The powder-liquid dual-chamber bag 1 has a powder chamber 11 and a liquid chamber 12 at its two ends, with a partition strip in the middle. A pipe opening 14 is provided at the end where the liquid chamber 12 is located, while a circular positioning hole 13 is provided around the perimeter of the end where the powder chamber 11 is located.

[0034] As attached Figure 3 and attached Figure 4As shown, the appearance inspection mechanism 3 is equipped with a first protective cover 31, a first plane mirror 32 and a first adjustable light 33. The appearance inspection mechanism 3 is used to inspect the overall shape of the powder liquid double chamber bag 1.

[0035] The light inspection ring belt 2 is a ring conveyor belt structure, and multiple clamping stations 21 are provided on the light inspection ring belt 2. The clamping stations 21 can limit and fix the powder-liquid double chamber bag 1, so that the powder-liquid double chamber bag 1 is continuously conveyed through the appearance inspection mechanism 3, the powder cavity inspection mechanism 4, and the liquid cavity inspection mechanism 5 as the light inspection ring belt 2 runs. Moreover, during the above conveying process, the clamping stations 21 are vertically arranged, and the powder-liquid double chamber bag 1 in the clamping station 21 also maintains a vertical state with the powder cavity 11 on top and the pipe opening 14 on the bottom.

[0036] Specifically, the clamping station 21 includes a powder chamber inspection area 211 and a liquid chamber fixing area 212. In order to facilitate a thorough inspection of each position of the powder chamber 11, the powder chamber inspection area 211 is recessed, and the powder chamber inspection area 211 is hollowed out around it to fully expose the powder chamber 11 of the powder-liquid dual-chamber bag 1 in the clamping station 21.

[0037] Each clamping station 21 on the light inspection ring belt 2 is equipped with a positioning pin 23 and a clamping hand 22.

[0038] The clamp handle 22 is used to hold and position the opening 14 of the powder-liquid dual-chamber bag 1. The clamp handle 22 is composed of two opposing clamping posts 221, the distance between which is adapted to the size of the opening 14. This ensures that the opening 14 is firmly fixed in the internal space of the clamp handle 22 when it enters, preventing the opening 14 from detaching from the clamp handle 22 on its own.

[0039] The positioning pins 23 are columnar structures with pointed tips, and are located at the left and right ends of the top of the powder chamber inspection area 211. The two positioning pins 23 are respectively aligned with and inserted into the two positioning holes 13 on the powder liquid double chamber bag 1, thereby achieving the limiting function of the powder liquid double chamber bag 1 and preventing the powder liquid double chamber bag 1 from falling out of the clamping station 21.

[0040] In actual production, the operator faces the visual inspection mechanism 3 and inspects each of the powder-liquid double-chamber bags 1 on the light inspection ring belt 2. The first adjustable lamp 33 provides a suitable light source for the visual inspection mechanism 3, and an existing lamp can be used; the first plane mirror 32 is tilted and the tilt angle is adjustable, so that the operator can inspect the powder-liquid double-chamber bags 1 from the back of the operator through the first plane mirror 32; the first protective cover 31 is set at the top of the visual inspection mechanism 3 and has the function of shielding light and preventing dust.

[0041] As attached Figure 5As shown, after the overall appearance and shape of the powder-liquid dual-chamber bag 1 are inspected, the light inspection ring belt 2 conveys the powder-liquid dual-chamber bag 1 to the powder chamber inspection mechanism 4. The powder chamber inspection mechanism 4 is used to inspect the powder chamber 11 of the powder-liquid dual-chamber bag 1. The powder chamber inspection mechanism 4 includes a second protective cover 41, a second plane mirror 42, and a second adjustable light 43.

[0042] The overall shape and structure of the powder chamber inspection mechanism 4 are similar to those of the appearance inspection mechanism 3. The operator faces the powder chamber inspection mechanism 4 and inspects each of the powder-liquid double-chamber bags 1 on the lamp inspection ring belt 2 one by one. The second adjustable lamp 43 is used to provide a suitable light source for the powder chamber inspection mechanism 4, and an existing lamp can be used; the second plane mirror 42 is tilted and the tilt angle is adjustable, so that the operator can inspect the powder-liquid double-chamber bags 1 from the rear of the operator through the second plane mirror 42; the second protective cover 41 is set on the top of the appearance inspection mechanism 3.

[0043] During the filling process of powder raw materials, foreign objects may fall into the powder chamber 11. In order to thoroughly inspect the powder chamber 11 of the powder-liquid dual-chamber bag 1 and facilitate the timely detection of foreign objects by the operators, the powder chamber inspection mechanism 4 is also equipped with a first powder chamber background plate 44 and a second powder chamber background plate 45.

[0044] The first background plate 44 and the second background plate 45 of the powder chamber are rectangular flat plates, each of which is a single color and is fixed behind the powder-liquid double-chamber bag 1. The first background plate 44 and the second background plate 45 of the powder chamber are different colors. Since foreign objects may be dark colors such as black, gray, brown, tan, and dark green with low brightness, or light colors such as white, yellow, red, pink, light yellow, and light blue with high brightness, at least two background plates are required. One of the two background plates is a dark color and the other is a light color. This ensures that the two background plates can form a relatively obvious color difference with the foreign objects of different colors, thereby assisting in the manual detection of foreign objects.

[0045] In some other embodiments, three or more background plates of different colors can be set inside the powder chamber inspection mechanism 4 to further improve the inspection effect. The selected colors are chosen to create a clear color difference from the colors of common foreign objects. In this embodiment, two background plates are set, with the first background plate 44 being black and the second background plate 45 being white. As the light inspection ring belt 2 conveys the powder liquid double-chamber bag 1 through the first background plate 44 and the second background plate 45, the operator can visually identify light-colored and dark-colored foreign objects in the powder chamber 11, ensuring product quality.

[0046] To further improve the inspection effect, a powder chamber vibrator 46 is also provided on the powder chamber inspection mechanism 4. A powder chamber vibrator 46 is correspondingly provided in front of both the first powder chamber background plate 44 and the second powder chamber background plate 45, capable of contacting and vibrating the powder chamber 11 of the powder-liquid double-chamber bag 1. The powder chamber vibrator 46 is existing technology; it can disperse the powder material in the powder chamber 11, preventing foreign objects buried in the powder material from passing through the inspection.

[0047] In order to ensure that the same powder liquid double chamber bag 1 can be inspected twice under the same color background of the powder chamber background plate before and after passing through the powder chamber vibrator 46, the first powder chamber background plate 44 and the second powder chamber background plate 45 both cover three adjacent clamping stations 21, and the powder chamber vibrator 46 is located in the middle of the three adjacent clamping stations 21.

[0048] As attached Figure 6 As shown, after the powder chamber 11 of the powder-liquid dual-chamber bag 1 is inspected, the light inspection ring belt 2 conveys the powder-liquid dual-chamber bag 1 to the liquid chamber inspection mechanism 5. The liquid chamber inspection mechanism 5 is used to inspect the liquid chamber 12 of the powder-liquid dual-chamber bag 1. The liquid chamber inspection mechanism 5 includes a third protective cover 51, a third plane mirror 52, a third adjustable light 53, and a first background plate 54 and a second background plate 55 for the liquid chamber.

[0049] The overall shape and structure of the liquid chamber inspection mechanism 5 are similar to those of the powder chamber inspection mechanism 4. The operator faces the liquid chamber inspection mechanism 5 and inspects each of the powder-liquid double-chamber bags 1 on the lamp inspection ring belt 2 one by one. The third adjustable lamp 53 is used to provide a suitable light source for the liquid chamber inspection mechanism 5, and an existing lamp can be used; the third plane mirror 52 is tilted and the tilt angle is adjustable, so that the operator can inspect the powder-liquid double-chamber bags 1 from the rear of the operator through the third plane mirror 52; the third protective cover 51 is set on the top of the appearance inspection mechanism 3.

[0050] The first background plate 54 and the second background plate 55 of the liquid chamber are completely similar in function and position to the first background plate 44 and the second background plate 45 of the powder chamber. The first background plate 54 and the second background plate 55 are used to create a clear color difference with the foreign objects in the liquid chamber 12 to assist in manual inspection. The first background plate 54 is black, and the second background plate 55 is white. During the process of the light inspection ring belt 2 conveying the powder-liquid dual-chamber bag 1 through the first background plate 54 and the second background plate 55, the operator can visually identify light-colored and dark-colored foreign objects in the liquid chamber 12, ensuring product quality.

[0051] The implementation principle of the above embodiments is as follows:

[0052] Each powder-liquid double-chamber bag 1 to be inspected is fixed in the clamping station 21 of the light inspection ring belt 2, and passes through the appearance inspection mechanism 3, the powder chamber inspection mechanism 4 and the liquid chamber inspection mechanism 5 in sequence as the light inspection ring belt 2 moves. In the appearance inspection mechanism 3, the operator inspects the front side of the powder-liquid double-chamber bag 1 under the illumination of the adjustable light and uses a plane mirror to inspect its rear side, rejecting products with unqualified overall shape. Then it enters the powder chamber inspection mechanism 4 and the liquid chamber inspection mechanism 5. With the assistance of the powder chamber background plate and the liquid chamber background plate, the powder chamber 11 and the liquid chamber 12 are inspected respectively, and products containing foreign objects are rejected, thereby ensuring the quality of the powder-liquid double-chamber bag 1.

[0053] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
