Abstract
Description
Technical Field
[0001] This utility model belongs to packaging machinery, and specifically relates to a drug clamping detection device for a multi-row strip bag back sealing machine. Background Technology
[0002] Multi-row strip bag back-sealing packaging machines typically include an unwinding mechanism, a feeding mechanism, a slitting mechanism, a slitting mechanism, a sealing mechanism, a transverse sealing mechanism, and a punching and rejecting mechanism. They are widely used for strip bag packaging of various pharmaceuticals or foods.
[0003] Currently, multi-row strip bag back-sealing machines sometimes encounter situations where medicine gets stuck at the seal during horizontal sealing. This can affect the seal's tightness, the product's weight stability, and ultimately, its quality. To solve this problem, manufacturers typically need to employ a large number of manual laborers for product screening and inspection, or add dedicated visual inspection equipment. Manual inspection not only increases long-term labor costs but also carries the risk of human error; adding dedicated visual inspection equipment requires significant investment in production line modifications and only provides reactive solutions. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a compact, timely detection device for drug-clamping in multi-row strip bag back sealing machines that can reduce production costs.
[0005] To solve the above problems, the present invention adopts the following technical solution: A drug clamping detection device for a multi-row strip bag back sealing machine includes a mounting plate frame, a camera mounting plate at the lower end of the mounting plate frame, and multiple cameras evenly distributed on the rear side of the camera mounting plate. The cameras are arranged vertically and correspond to one or more rows of strip bags. Lenses are respectively installed on the upper end of the cameras. 45-degree mirrors are evenly distributed on the upper end of the mounting plate frame. The cross-section of the 45-degree mirror is an isosceles right triangle and is located above the lens of each camera. It is used to change the optical path between the strip bag and the lens to 90 degrees, so as to capture the image of the horizontal seal of each row of strip bags. A supplementary light is installed on the front side of the middle of the mounting plate via a supplementary light mounting plate to provide a stable light source for the horizontal sealing position of the strip.
[0006] As a further preferred option, the device also includes an industrial control computer, and the camera is a high frame rate digital network camera, which is connected to the signal input terminal of the industrial control computer via a network cable.
[0007] As a further preferred option, the lens is a short focal length lens.
[0008] As a further preferred embodiment, the mounting plate frame includes a mounting back plate and upright plates fixed to both ends of the mounting back plate. The camera mounting plate and the fill light mounting plate are respectively fixedly connected between the two upright plates. An upper cover plate is fixed between the upper ends of the mounting back plate and the upright plates at both ends. Multiple sets of positioning plates are evenly distributed and fixed on the front side of the mounting back plate. The 45-degree mirror is inserted between each set of positioning plates and limited by the L-shaped support plate fixed to each set of positioning plates.
[0009] As a further preferred embodiment, the supplementary light mounting plate is a profiled plate with three surfaces. The two rear surfaces form a right angle and rest against the step in the middle of the upright plate. The front surface is an inclined plane that slopes forward and upward. The supplementary light is fixed below the inclined plane and faces obliquely upward to improve the supplementary lighting effect and facilitate the adjustment of the lighting angle.
[0010] As a further preferred option, the supplementary light uses an LED parallel light source.
[0011] As a further preferred option, an air-cooling pipe is fixed on the mounting plate below the supplementary light. One end of the air-cooling pipe is closed, and the other end is connected to the air source through a flexible hose. Air outlets are provided on the air-cooling pipe at the corresponding strip positions to cool down the strip bags.
[0012] The beneficial effects of this utility model are: 1. Because 45-degree mirrors are evenly distributed on the upper end of the mounting frame, and the cross-section of each 45-degree mirror is an isosceles right triangle and is located above the lens of each camera, the optical path between the strip bag and the lens is changed to 90 degrees by the 45-degree mirror, so that the camera can capture the image of the horizontal seal of each row of strip bags; by transmitting the image to the industrial control computer, the medicine clamping of multiple rows of strip bags can be detected in time according to the image, and the subsequent punching and rejection mechanism can be controlled to reject unqualified products. The structure is compact and can reduce production costs.
[0013] 2. By installing a supplementary light on the front side of the mounting plate in the middle of the mounting frame, a stable light source can be provided for the horizontal sealing position of the strip, thereby ensuring the acquisition of stable detection images and guaranteeing the accuracy of the detection.

Detailed Implementation
[0020] like Figures 1-5 As shown, this utility model relates to a drug-clamping detection device for a multi-row strip bag back-sealing machine, including a mounting frame 1. A camera mounting plate 103 is provided at the lower end of the mounting frame 1. Multiple cameras 2 are evenly fixed to the rear side of the camera mounting plate 103 by screws. The cameras 2 are arranged vertically and correspond to one or more rows of strip bags. Lenses 8 are respectively threaded onto the upper end of the cameras 2. This embodiment takes six cameras as an example, and each camera 2 corresponds to two adjacent rows of strip bags.
[0021] The mounting plate frame 1 includes a rectangular mounting back plate 101 and upright plates 102 fixed to both ends of the mounting back plate 101 by bolts. Three oblong holes are evenly distributed on the mounting back plate 101 to fix the device to the body of the multi-row bag back sealing machine. The camera mounting plate 103 is fixed between the two upright plates 102 by bolts. An upper cover plate 104 is fixed between the mounting back plate 101 and the upper ends of the upright plates 102 by screws. Multiple sets of rectangular positioning plates 105 are evenly distributed and fixed on the front side of the mounting back plate 101. Each set of positioning plates 105 consists of two plates forming a rectangular slot. Each rectangular slot corresponds one-to-one with the camera 2 below.
[0022] 45-degree mirrors 6 are evenly distributed on the upper end of the mounting plate frame 1. The 45-degree mirrors 6 are inserted into the rectangular slots between each group of positioning plates 105 and are limited by L-shaped support plates 5 fixed on each group of positioning plates 105 by screws. The cross-section of the 45-degree mirrors 6 is an isosceles right triangle and is located above the lens 8 of each camera 2. It is used to change the optical path between the strip bag and the lens 8 to 90 degrees, so as to capture the image of the horizontal seal of each row of strip bags.
[0023] A supplementary light 3 is mounted on the front side of the middle section of the mounting frame 1 via a supplementary light mounting plate 4 to provide a stable light source for the horizontal sealing position of the strip. The supplementary light mounting plate 4 is a profiled plate with three sides and is fixedly connected between two upright plates 102 by screws. The two rear sides of the plate form a right angle and rest against the step in the middle of the upright plate 102. The front side of the plate is an inclined surface that slopes forward and upward. The supplementary light 3 is fixed to the underside of the inclined surface by screws and faces obliquely upward to improve the supplementary lighting effect and facilitate the adjustment of the illumination angle.
[0024] The device also includes an industrial control computer. The camera 2 is a high frame rate digital network camera and is connected to the signal input terminal of the industrial control computer via a network cable. The lens 8 is preferably a short-throw lens. The supplementary light 3 uses an LED parallel light source. The industrial control computer is an industrial vision inspection host, equipped with multiple gigabit network ports that are connected one-to-one with the camera 2 to realize the acquisition of inspection images; another network port communicates with the main control PLC of the multi-row strip bag back sealing machine via a network cable, thereby realizing the synchronization of inspection cycle and the output of inspection results, enabling the multi-row strip bag back sealing machine to realize automatic rejection and interlocking alarm functions.
[0025] A cooling pipe 7 is fixedly installed between the two upright plates 102 on the mounting frame 1, below the supplementary light 3. One end of the cooling pipe 7 is closed, and the other end is connected to the air source through a flexible hose. Multiple air outlets are provided on the cooling pipe 7 corresponding to the strip positions to cool down the strip bag.
[0026] During operation, the device is bolted to the body of the multi-row strip bag back sealing machine via the oblong holes on the mounting plate 101, and is located between the horizontal sealing mechanism and the punching and rejecting mechanism. When the horizontally sealed multi-row strip bags fall directly in front of the device, a stable light source is provided to the horizontal sealing position of the strips through the external power supply of the supplementary light lamp 3. When the strip bag stepping pauses for horizontal sealing, the light reflected from the horizontal sealing positions of the two adjacent strips is collected by the lens 8 of each camera 2 through the 45-degree mirror 6. The images formed by the camera 2 are transmitted to the industrial control computer via network cable. The industrial control computer determines whether there is any drug jamming at the horizontal sealing position of the strips based on the received images. If drug jamming is found, the industrial control computer sends a signal to the main control PLC of the multi-row strip bag back sealing machine, thereby controlling the subsequent punching and rejecting mechanism to reject the unqualified products. When the inspected strip bags pass in front of the air-cooling pipe 7, they are cooled by the cold air discharged through the air-cooling pipe 7.
[0027] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
