Description

Technical Field

[0001] The present invention relates to the field of sorting equipment, and in particular to a visual inspection device for boxed liquid medicine preparations with a front and back adjustment function. Background Art

[0002] In the production process of boxed liquid pharmaceutical preparations, box transport, orientation detection, and sorting and adjustment are key steps. Ensuring that the boxes enter subsequent processes in the correct orientation is crucial. Sorting and flipping play an indispensable role in visually inspecting the front and back of the boxes. From the perspective of product consistency and quality control, the packaging of boxed liquid pharmaceutical preparations is subject to strict regulations. The front of the box typically displays key information such as the product name, specifications, and instructions for use, while the back may include information such as the ingredient list, shelf life, and production batch. If the box is oriented incorrectly, the product information display will be confusing. In large-scale production, manually checking the orientation of each box is both time-consuming and labor-intensive, and it is difficult to guarantee 100% accuracy.

[0038] To make the purpose, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0039] See also Figures 1-9As shown, the present invention provides a visual inspection device for boxed liquid preparations with a front-to-back adjustment function. A base 1 serves as a basic support component. A first conveyor 2 and a second conveyor 8 are sequentially arranged on the base 1 and interconnected, for sequentially conveying box bodies 13. The first conveyor 2 is used to transport the box bodies from a starting position toward the second conveyor 8. A swing support structure 4 is arranged on the lower side of the first conveyor 2 opposite the second conveyor 8, providing horizontal deflection support for the first conveyor 2 and providing a support point for the first conveyor 2 during horizontal deflection. A swing drive mechanism 6 is also arranged on the base 1 to drive the first conveyor 2 to deflect. A visual detector 3 is installed along the conveying direction of the first conveyor 2 to detect the front and back of the box bodies. A lateral conveyor 7 is also arranged along the conveying direction of the first conveyor 2 to guide the box bodies for output. A linear drive assembly 9 is arranged on the base 1 and connected to the second conveyor 8 to adjust the distance between the second conveyor 8 and the first conveyor 2. A material separation plate structure 10 is installed on the second conveyor 8, forming two collection channels. A stop structure 12 is installed in one channel for collecting forward-facing boxes, and a forward-reverse adjustment mechanism 11 is installed in the other channel for collecting reverse-facing boxes. The overall system, through the interaction of various components, realizes a series of automated operations, from box conveying, visual inspection, guided output, sorting on the second conveyor, adjustment of reverse-facing boxes, and collection of forward-facing boxes. This can efficiently and accurately handle the box conveying and direction adjustment work.

[0040] See the instructions attached Figure 1 and Figure 2 As shown, two first frames 201 are arranged in parallel, with a first conveyor belt 202 disposed between them, achieving connection and coordination with the two first frames 201. A first drive motor 203 is mounted on one of the first frames 201, with its power output end connected to the first conveyor belt 202, providing power for the operation of the first conveyor belt 202. A swing support structure 4 is disposed below the end of the first conveyor 2 opposite the second conveyor 8. A supporting balance wheel structure 5 is disposed below the junction of the first conveyor 2 and the second conveyor 8. A visual detector 3 is disposed above the two first frames 201. The visual detector 3 utilizes principles such as optical imaging to capture and analyze images of the boxes transported on the first conveyor 2, determine the forward and reverse orientation of the boxes, and provide information for subsequent sorting and adjustment. The visual detector 3 utilizes existing technology and is well known to those skilled in the art. The first conveyor 2 and its related components work together to achieve stable transmission of the box body, and use the visual detector 3 to detect the positive and negative directions of the box body during the transmission process; the swing support structure 4 and the supporting balance wheel structure 5 cooperate to enable the first conveyor 2 to adjust the angle when necessary to meet the working requirements of the overall equipment, laying the foundation for subsequent box body sorting, adjustment and other processes.

[0041] See the instructions attached Figure 1 、 Figure 6 and Figure 7 As shown, the swing support structure 4 includes a first lower bracket 401 fixedly arranged on the lower side of the first conveyor 2, and the first lower bracket 401 is fixedly provided with an upper support ear 402 and a lower support ear 403 in the up and down directions respectively, and a swing support shaft 406 is provided between the upper support ear 402 and the lower support ear 403 to provide an axis for the swing of the first conveyor 2, and a fixed frame 405 is fixedly provided on the base 1, and a fixed block 404 for supporting the rotation of the swing support shaft 406 is fixedly provided on the fixed frame 405, and a first swing support wheel for rolling against the upper surface of the base 1 is provided on the bottom side of the first lower bracket 401. When the first conveyor swings, it rolls in contact with the upper surface of the base to reduce the friction force when the first conveyor swings, and at the same time plays a role in auxiliary support of the first conveyor, making the swinging process smoother. The swing support structure 4 provides a stable horizontal deflection support point and rotation axis for the first conveyor 2 through the coordinated cooperation of various components, so that the first conveyor 2 can smoothly adjust the horizontal angle around the swing support axis under the action of the swing drive mechanism 6. At the same time, the first swing support wheel assists it in swinging smoothly to meet the overall equipment's requirements for adjusting the transmission angle of the box body 2.

[0042] See the instructions attached Figure 3 and Figure 4 As shown, the swing drive mechanism 6 includes a swing drive motor 601 fixed on the base 1 through a fixed seat 602, and the output shaft end of the swing drive motor 601 is connected to the swing wheel 603 through a reducer. A third lower bracket 607 is provided on the lower side of the first conveyor 2, and a second hinge shaft 605 is rotatably provided on the third lower bracket 607. The eccentric position of the swing wheel 603 is rotatably provided with a first hinge shaft 604, and an eccentric connecting rod 606 is connected between the first hinge shaft 604 and the second hinge shaft 605. The supporting balance wheel structure 5 includes a second lower bracket 501 provided on the lower side of the first conveyor 2, and a second swing support wheel 502 for rolling abutment with the upper surface of the base 1 is provided on the bottom side of the second lower bracket 501. When the first conveyor 2 swings, it rolls in contact with the base 1 to assist in supporting the first conveyor 2 and reduce the swinging friction. The swing drive mechanism 6 is powered by a swing drive motor 601. This motor's rotation is then converted through transmission via a reducer, swing wheel 603, eccentric connecting rod 606, and other components to cause the first conveyor 2 to swing about the swing support shaft 406, thereby adjusting the transmission angle of the first conveyor 2. The second swing support wheel 502 assists in the smooth swing of the first conveyor 2, meeting the device's requirement for flexible adjustment of the transmission angle of the cassette 13. The coordinated operation of the entire system allows the cassette to flexibly adjust its transmission angle according to actual needs during the transfer process, improving the device's adaptability and operating efficiency.

[0043] See the instructions attached Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the lateral conveyor 7 is equipped with two opposing wheel bases 701. Each wheel base 701 is rotatably mounted with at least four pulleys 702. The pulleys 702 are meshed and connected to a side conveyor belt 703. A mounting bracket 706 is fixedly mounted on the wheel base 701. The mounting bracket 706 is provided with a third drive motor 704 for driving one of the pulleys 702. The ends of the two wheel bases 701 facing the second conveyor 8 are each provided with a guide side plate 705 for guiding the cassettes 13 in a predetermined direction, preventing them from shifting during transport and ensuring accurate transfer from the lateral conveyor 7 to the second conveyor 8. Push links 709 are fixedly mounted on the undersides of the two mounting brackets 706. A first electric telescopic rod 708 is provided on the underside of the first conveyor 2 to adjust the spacing between the two push links 709. Through the coordinated operation of various components, the lateral conveyor 7 achieves the function of laterally transferring cassettes from the first conveyor 2 to the second conveyor 8. The third drive motor 704 drives the pulley 702 to drive the side conveyor belt 703 to transport the box body. The guide side plate 705 ensures the accurate direction of box body transmission. The first electric telescopic rod 708 adjusts the spacing between the wheel base plates 701 to adapt to different box body sizes, meeting the equipment's requirements for diversified box body transmission and improving the working efficiency and adaptability of the entire equipment.

[0044] See the instructions attached Figure 1 and Figure 2 As shown, the second conveyor 8 includes two second frames 801 distributed in parallel, a second conveyor belt 802 is arranged between the two second frames 801, one of the second frames 801 is provided with a second driving motor 803 for driving the second conveyor belt 802, the material dividing partition structure 10 is arranged on the upper side of the second conveyor 8, and the linear drive assembly 9 is arranged on the lower side of the second conveyor 8.

[0045] See the instructions attached Figure 6As shown, the linear drive assembly 9 includes a frame 901 fixedly mounted on the base 1. Two or more moving wheels 905 are rotatably mounted on the lower side of each second frame 801. The upper surface of the frame 901 is provided with a wheel groove 904 for cooperating with the moving wheel 905 to guide movement. By rolling in the wheel groove 904, the friction force during movement of the second frame 801 is reduced, allowing the second frame 801 to move relatively smoothly on the frame 901, playing a role in supporting and assisting movement. A linear slide 906 is provided on the upper side of the frame 901. A linear slider 903 is fixedly mounted on the lower side of the second frame 801. A cylinder 902 is fixedly mounted on the frame 901 for driving the linear slider 903 to slide within the linear slide 906. Through the coordinated operation of various components, the linear drive assembly 9 achieves precise adjustment of the position of the second conveyor 8, specifically, adjusting the spacing between the second conveyor 8 and the first conveyor 2. Frame 901 provides stable support and guidance. Moving wheels 905 cooperate with wheel grooves 904 to ensure smooth and accurate movement of the second frame 801. Linear slides 903 and linear guideways 906 precisely transmit power, and cylinder 902 serves as the power source to drive the entire adjustment process. This precise spacing adjustment capability allows the device to adapt to the transport needs of boxes of varying sizes, improving its versatility and operating efficiency, and ensuring more stable and efficient transfer of boxes between the first conveyor 2 and the second conveyor 8.

[0046] See the instructions attached Figure 3 As shown, the material separation partition structure 10 includes three parallel partitions 1003 that form two collection channels. A hanger 1001 is fixedly mounted on the second frame 801. The hanger 1001 is provided with three suspension rods 1002 for respectively fixing and hoisting the three partitions 1003. These two channels are used to sort and collect boxes that have passed visual inspection and preliminary transmission according to forward and reverse directions, realizing the classification and processing of boxes in different states, ensuring that subsequent processes can carry out targeted operations on boxes in different directions.

[0047] See the instructions attached Figure 6 、 Figure 8 and Figure 9As shown, the forward and reverse adjustment mechanism 11 includes a rotating support block 1102, which is rotatably arranged between two partitions 1003. A first servo motor 1101 is fixedly provided on the partition 1003 to drive the rotating support block 1102 to rotate. A sliding cavity 1107 is provided in the rotating support block 1102, and a guide groove 1103 is provided on the outer side of the rotating support block 1102 to achieve communication between the sliding cavity 1107 and the outside. Clamping sliders 1109 are slidably provided at both ends of the sliding cavity 1107, and a second electric telescopic rod 1108 is provided between the two clamping sliders 1109 to adjust the distance between them. Each clamping slider 1109 is fixedly provided with a slide 1104 through the guide slot 1103. A clamping plate 1106 is fixedly provided on the slide 1104, which is in direct contact with the box body. By adjusting its position and driving the rotating support block 1102 when it rotates, the clamping and flipping operations of the box body are achieved. It is the direct actuator for achieving the forward and reverse adjustment of the box body. The two clamping plates 1106 are provided with a plurality of anti-slip pads 1105 on the side close to each other to increase the friction between the clamping plates 1106 and the box body, preventing the box body from sliding during the clamping and flipping process, ensuring that the box body can be stably clamped and adjusted in direction. The forward and reverse adjustment mechanism 11 achieves precise adjustment of the reverse box body through the coordinated work of various components. First, the second electric telescopic rod 1108 adjusts the spacing between the clamping plates 1106 according to the size of the box, ensuring stable clamping of the box. Then, the first servo motor 1101 drives the rotating support block 1102, causing the clamping plates 1106 and the box to flip together, adjusting the reversed box to the forward direction. This mechanism, combined with the material separation plate structure 10, ensures that the equipment can effectively handle boxes in different orientations, improving the integrity and accuracy of the entire device's box handling and meeting the demand for box orientation adjustment in actual production.

[0048] See the instructions attached Figure 5 As shown, the blocking structure 12 includes a rotating shaft 1202 rotatably disposed between two partitions 1003. One end of the rotating shaft 1202 is driven by a second servo motor 1201 fixed to the partition 1003. A baffle 1203 is disposed on the rotating shaft 1202. When the baffle 1203 rotates to a position perpendicular to the direction of cassette transport, it blocks the forward cassette from further transport, forcing the cassette to remain at that position, thus achieving a collection function. When the baffle 1203 rotates to a position parallel to the cassette transport direction or offset by a certain angle, the cassette can pass smoothly, thus achieving a release function.

[0049] Working principle:

[0050] During use, the cassettes 13 containing liquid medicine are first transported by the first conveyor 2. The first drive motor 203 of the first conveyor 2 drives the first conveyor belt 202. The swing drive motor 601 of the swing drive mechanism 6 drives the swing wheel 603 via a speed reducer. This swings the first conveyor 2 about the swing support shaft 406 via the eccentric connecting rod 606, adjusting the transport angle. The second swing support wheel 502 of the support wheel structure 5 provides auxiliary support.

[0051] As the boxes are transported by the first conveyor 2, the visual inspection device 3 visually inspects the front and back of the boxes 13. After inspection, the first motorized telescopic rod 708 of the lateral conveyor 7 adjusts the distance between the two push links 709 to accommodate the size of the boxes 13. The third drive motor 704 drives the pulley 702 to rotate the side conveyor belt 703, guiding the boxes out of the conveyor.

[0052] The three partitions 1003 of the material separation partition structure 10 form two collection channels. As the boxes are transferred to the second conveyor 8 under the swinging motion of the first conveyor 2, they are sorted into different channels based on the visual inspection results. During this process, the cylinder 902 of the linear drive assembly 9 pushes the linear slide 903 to slide within the linear slide 906, causing the second conveyor 8 to move within the wheel groove 904 via the moving wheel 905. This allows the second conveyor 8 to adjust its distance from the first conveyor 2 to achieve closer contact when receiving materials and farther distance from the first conveyor 2 when the first conveyor 2 swings.

[0053] After entering the reverse box body provided with the forward and reverse adjustment mechanism 11 channel, after accumulating a certain number, the second electric telescopic rod 1108 adjusts the spacing of the clamping slider 1109 so that the anti-slip pad 1105 of the clamping plate 1106 clamps the box body, and the first servo motor 1101 drives the rotating support block 1102 to rotate and flip 180°. The second electric telescopic rod 1108 adjusts the spacing of the clamping slider 1109 to increase, so that the anti-slip pad 1105 of the clamping plate 1106 releases the box body and falls on the second conveyor 8 for continued transmission. During this process, the second servo motor 1201 drives the rotating shaft 1202 and the baffle 1203 to rotate to block the forward box body 13. After the forward and reverse adjustment mechanism 11 flips and moves the reverse box body 13, the baffle 1203 releases the blockage of the forward box body 13, thereby realizing cross-transmission of the box bodies 13 on the two collection channels to avoid side-by-side overlap during transmission.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
