Detailed Implementation

[0025] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] A device for detecting the item codes of printed cigarette rolls, such as... Figure 1 As shown, it includes a conveyor belt 1 for conveying printed cigarette rolls, and a label recognition station 2 and a physical object recognition station 3 arranged sequentially along the conveying direction of the conveyor belt 1. The label recognition station 2 is located upstream, and the physical object recognition station 3 is located downstream.

[0027] The label recognition station 2 is equipped with a barcode reader 21 for reading labels on cigarette rolls. The choice of barcode reader 21 is not limited; any commonly used barcode reader in the existing technology can be used, such as the Hikvision MV-IDC007X smart barcode reader. The barcode reader 21 can read the label barcode or QR code and convert the encoded information into a recognizable form. This encoded information usually contains key data such as product tracking, production control, and automatic identification.

[0028] The number and installation location of the barcode reading cameras 21 are not limited, as long as the labels of the cigarette rolls are within the field of view of the barcode reader.

[0029] For example, in some implementation methods, such as Figure 2 As shown, the label recognition station 2 is equipped with several barcode reading cameras 21. These cameras are evenly arranged in a ring around the printed cigarette rolls located at the label recognition station 2. The cameras can achieve 360° omnidirectional recognition, allowing information to be read regardless of the orientation of the label on the printed cigarette rolls. In this embodiment, the conveyor belt 1 does not need to be stopped during label recognition, resulting in high work efficiency.

[0030] In order to install several barcode reading cameras 21 without affecting the conveyor belt 1, such as Figure 3As shown, several supports can be set on both sides of the conveyor belt 1, and the tops of the supports are connected by a top plate, so that the top plate is directly above the conveyor belt 1. The barcode reader camera 21 can be directly mounted on the top plate through a connecting structure. The connecting structure can be a universal connector to facilitate adjustment of the barcode reader camera's field of view. For example, the connecting structure includes a fixed cylinder connected to the top plate by a screw and nut structure, a movable cylinder connected to the fixed cylinder by a rotating bearing, a connecting shaft perpendicularly connected to the movable cylinder, and a U-shaped frame rotatably connected to both ends of the connecting shaft. The barcode reader camera 21 is connected to the U-shaped frame. The position of the barcode reader camera 21 can be adjusted up and down by adjusting the fixed cylinder through the screw and nut structure; the position of the barcode reader camera 21 can be adjusted by rotating the movable cylinder; and the position of the barcode reader camera 21 can be adjusted by rotating the U-shaped frame. In some embodiments, to avoid the influence of external light on the barcode reader camera 21, a side plate is also provided on the side of the top.

[0031] For example, in some implementation methods, such as Figure 4 As shown, the label recognition station 2 is equipped with a barcode reader 21 and a control device for rotating the barcode reader 21 around the cigarette reel printed material located at the label recognition station 2. The control device includes a turntable 51 suspended above the conveyor belt 1 and a rotating component 52 that drives the turntable 51 to rotate. The barcode reader 21 is connected to the side edge of the turntable 51 via a connector. The rotating component 52 can be a motor, and the center of the turntable 51 is connected to the motor output shaft via a reducer. The structure of the connector can be the same as the universal connector mentioned above. 360° omnidirectional recognition can be achieved through the rotation of the barcode reader 21, allowing information to be read regardless of the orientation of the cigarette reel printed material's label. During installation, a bracket and top plate can also be provided, and the rotating component 52 can be mounted on the top plate.

[0032] Typically, conveyor belt 1 needs to be stopped or its speed reduced to prevent the printed cigarette rolls from leaving the rotation range of the barcode reader 21. Based on this, to improve work efficiency, rotational barcode reading can be achieved without stopping or slowing down the conveyor belt 1 in some embodiments, such as... Figure 4As shown, the control device also includes a guide rail 53 suspended above the conveyor belt 1, and a moving part 54 that drives the rotating part 52 to move along the guide rail 53. The length direction of the guide rail 53 is parallel to the conveying direction of the conveyor belt 1. The moving part 54 can be a cylinder or a ball screw structure, for example, connecting the motor body to the cylinder piston rod; or connecting the motor body to the ball screw through a ball nut, and then using a second motor to control the rotation of the ball screw. The moving part 54 controls the translational speed of the rotating part 52 to be consistent with the speed of the conveyor belt 1, so that the turntable 51 and the cigarette reel printing are relatively stationary in the conveying direction. Therefore, even during the conveying process, the turntable 51 can rotate around the center of the cigarette reel printing, ensuring that the barcode reader camera 21 on the turntable 51 can read the cigarette reel printing 360°. During installation, a bracket and a top plate can also be set, with the guide rail 53 set on the top plate.

[0033] Furthermore, in order to ensure that the rotating component 52, or the rotating component 52 and the moving component 54, works promptly when the printed cigarette reel is in place, in some embodiments, the label recognition station 2 is also equipped with a first sensor 22 for detecting whether the printed cigarette reel is in place. For example, it can be an infrared sensor. The infrared sensor's generating end and receiving end are respectively set on both sides of the label recognition station 2 on the conveyor belt 1. When the printed cigarette reel reaches the label recognition station 2, it will block the infrared light. Therefore, when the receiving end cannot receive the infrared light, it indicates that the printed cigarette reel is in place. Then, the first sensor 22 is connected to the control device via a first controller signal. When the receiving end cannot receive the infrared light, the first sensor 22 outputs a signal to the first controller, and the first controller outputs a signal to the control device to start operation. Any commonly used controller in the prior art can be selected as the first controller.

[0034] The physical identification station 3 is equipped with a visual inspection device 31 for inspecting the appearance of printed cigarette rolls and a weight inspection device 32 for inspecting the weight of printed cigarette rolls.

[0035] The choice of visual inspection device 31 is unrestricted; any commonly used inspection camera in the prior art, such as a CCD camera, can be selected. The visual inspection device 31 can convert optical images into digital signals. The number and installation location of the visual inspection devices 31 are unrestricted, as long as the printed material on the cigarette reel is within the field of view of its camera. For example, in some embodiments, such as... Figure 2 As shown, the visual inspection device 31 is located on the side of the physical object recognition station 3 of the conveyor belt 1.

[0036] The choice of weight detection device 32 is not limited; any commonly used weight sensor in the prior art can be selected. The weight detection device 32 can convert physical weight into a measurable electrical signal or other form of signal. For ease of measurement, the weight detection device 32 is typically positioned below the conveyor belt 1, and weight detection can be performed when the printed cigarette rolls are conveyed to the location of the weight detection device 32. In some embodiments, to reduce friction between the weight detection device 32 and the conveyor belt 1, such as... Figure 3 As shown, it also includes a lifting component 6 for controlling the lifting and lowering of the weight detection device 32 to contact or separate from the conveyor belt 1. The lifting component 6 can be a cylinder. When the printed cigarette rolls are conveyed to the physical identification station 3, the lifting component 6 controls the weight detection device 32 to rise to contact the conveyor belt 1 and the printed cigarette rolls on it; after the detection is completed, the lifting component 6 controls the weight detection device 32 to fall to separate from the conveyor belt 1.

[0037] To ensure the lifting mechanism 6 operates promptly upon the arrival of the printed cigarette roll, in some embodiments, the physical identification station 3 is equipped with a second sensor 33 for detecting whether the printed cigarette roll is in position. The second sensor 33 is connected to the lifting mechanism 6 via a second controller signal. The second sensor 33 is identical to the first sensor 22 and can be an infrared sensor. When the infrared sensor receiver fails to receive infrared light, the second sensor 33 outputs a signal to the second controller, which then outputs a signal to the lifting mechanism 6 to activate it. Any commonly used controller in the prior art can be selected as the second controller.

[0038] To further ensure the accuracy of weighing, a control device for controlling the start and stop of the conveyor belt 1 is also included, namely the motor on the drive wheel of the conveyor belt 1. The second sensor 33 is connected to the control device through the second controller signal. When the infrared sensor receiver cannot receive infrared light, the second sensor 33 outputs a signal to the second controller, and the second controller outputs a signal to the control device to stop the conveyor belt 1, so that weighing is performed in a static state, and the weighing result is more accurate.

[0039] Based on the above, when the material code detection equipment of this application is used, the printed cigarette reels are transported on conveyor belt 1. When they reach the label recognition station 2, the barcode reader 21 reads the material information from the QR code on the label of the printed cigarette reel, thus obtaining the "code" information. When they continue to be transported to the physical identification station 3, the visual inspection device 31 and the weight detection device 32 identify the appearance and weight of the printed cigarette reel, thus obtaining the "object" information. When the appearance and weight of the printed cigarette reel match the information on the label barcode, i.e., the material code matches, the product is qualified and can proceed downstream; when the appearance and weight of the printed cigarette reel do not match the information on the label barcode, i.e., the material code does not match, the product is unqualified.

[0040] To facilitate item code comparison, a central controller and an alarm device are also included. The receiving end of the central controller is connected to the barcode reader 21, the visual inspection device 31, and the weight detection device 32, respectively; the output end of the central controller is connected to the alarm device. The central controller confirms whether the item codes match based on the code information read by the barcode reader 21 and the item information identified by the visual inspection device 31 and the weight detection device 32, and reports the information to the alarm device to trigger an alarm if there is a discrepancy. Any commonly used controller in the prior art can be used as the central controller.

[0041] In some implementations, in order to promptly separate out defective products, such as Figure 2 As shown, it also includes a rejection channel 11 and a rejection device 4 for pushing non-conforming cigarette roll printing from the conveyor belt 1 to the rejection channel 11; the rejection device 4 is connected to the output signal of the central controller. When the item codes are inconsistent, the central controller reports the information to the alarm device to trigger an alarm and controls the rejection device 4 to operate. The structure of the rejection device 4 is not limited; for example, the rejection device 4 includes a cylinder and a push plate disposed at the end of the cylinder piston rod, the piston rod of the cylinder extending to push the non-conforming product into the rejection channel 11. In some embodiments, the push plate is arc-shaped to increase the pushing area and ensure the rejection of non-conforming products.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
