In addition, cigarette carton code identification can also be used to count and analyze information such as the production, sales volume, and origin of tobacco products, providing data support and management decisions for the tobacco industry.
[0003] Since the diameter of thin cigarettes is smaller than that of ordinary cigarettes, the length of the cigarettes is also shortened accordingly. Therefore, in order to accommodate the same number of cigarettes, the cigarette box of thin cigarettes needs to be shorter. The height of the cigarette box of thin cigarettes is also different from that of the cigarette box of ordinary cigarettes. Since the codes of cigarette cartons are usually located on the side walls of the cigarette boxes, the identification device for identifying the codes is also set on the side of the cigarette cartons for transmission and is usually fixed. When it is necessary to perform code identification on a thin cigarette box with a lower height, it is usually necessary to manually adjust the height of the identification device so that it is directly opposite to the code on the side wall of the thin cigarette box.

[0032] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0033] like Figure 1-Figure 9As shown, the identification device for detecting cigarette codes provided in this embodiment includes a feed rack 2 for containing cigarette bodies 1, a code reader 3 for collecting codes on the cigarette bodies 1, and a position adjustment component for identifying codes of cigarette bodies 1 at different heights. The feed rack 2 is a hollow structure with a cross-sectional area slightly larger than that of the cigarette bodies 1, so that the cigarette bodies 1 can be stacked inside the feed rack 2. A discharge port 21 is provided on one side of the feed rack 2. A sliding cavity 22 is provided on the inner wall of the end, and a baffle plate 23 is provided inside the sliding cavity 22. The distance between the bottom end of the baffle plate 23 and the bottom end of the discharge port 21 is equal to the height of a single cigarette body 1, so that the single cigarette body 1 at the bottom can be easily sent out from the discharge port 21 without causing other cigarette bodies 1 to be output. A discharge assembly is provided at the lower end of the feeding rack 2, and the discharge assembly is used to push out the cigarette bodies 1 inside the feeding rack 2 one by one. The discharge assembly is arranged on the side of the feeding rack 2 away from the discharge port 21, and includes a third telescopic member 6 and a push plate 61 connected to the movable end of the third telescopic member 6, the fixed end of the third telescopic member 6 is connected to the outer wall of one side of the feeding rack 2, the third telescopic member 6 drives the push plate 61 to move, and the cigarette body 1 located at the bottom of the feeding rack 2 is pushed out from the discharge port 21 for discharge, and a workbench 24 is provided on one side of the feeding rack 2 near the discharge port 21, and a conveying device 25 is provided on the workbench 24, and the conveying device 25 is used to transport the cigarette body 1 output from the feeding rack 2. Preferably, a There is a connecting frame 26, on which a photoelectric sensor 27 is arranged. The photoelectric sensor 27 and the third telescopic member 6 are electrically connected to the controller 4. When the discharging assembly pushes the cigarette body 1 out of the discharging port 21, the photoelectric sensor 27 detects the cigarette body 1 below and transmits a signal to the controller 4. The controller 4 controls the third telescopic member 6 to retract and wait for the next discharging cycle. After the third telescopic member 6 retracts, the cigarette body 1 in the feeding frame 2 will continue to fall downward under its own gravity and wait for discharging.
[0034] The position adjustment component includes a controller 4, a first telescopic member 41 and a second telescopic member 42. The fixed end of the first telescopic member 41 is connected to the bottom inner wall of the discharge port 21, the movable end of the first telescopic member 41 is connected to the lower end surface of the baffle plate 23, the fixed end of the second telescopic member 42 is connected to one side of the workbench 24, and the code reader 3 is connected to the movable end of the second telescopic member 42. The upper end of the feeding frame 2 is provided with a first distance sensor 43, and the lower part of the baffle plate 23 is provided with a second distance sensor 44. The first telescopic member 41, the second telescopic member 42, the first distance sensor 43 and the second distance sensor 44 are provided. The distance sensor 43 and the second distance sensor 44 are both electrically connected to the controller 4. When the first distance sensor 43 detects the height of a single cigarette body 1 in the feeding rack 2, the signal is transmitted to the controller 4. The controller 4 drives the first telescopic member 41 to drive the baffle plate 23 to move, and after the second distance sensor 44 detects the distance between the bottom end of the baffle plate 23 and the discharge port 21, the signal is transmitted to the controller 4. The controller 4 controls the second telescopic member 42 to drive the code reader 3 to move. When the code recognition of cigarette bodies 1 of different specifications is performed, the code reader 3 is firstly detected by the first telescopic member 41. A distance sensor 43 detects the distance between the bottom of the feeding rack 2 to obtain a value m1, a single cigarette body 1 is placed in the feeding rack 2, and the distance between the first distance sensor 43 and the upper end of the single cigarette body 1 is detected by the first distance sensor 43 to obtain a value m2, and the height value m3 of the single cigarette is obtained by m1-m2, and the first telescopic member 41 is controlled by the controller 4 to drive the baffle plate 23 to move. When the second distance sensor 44 detects that the distance m4 between the bottom end of the baffle plate 23 and the bottom of the discharge port 21 is equal to m3, the signal The height of the code reader 3 is transmitted to the controller 4, and the controller 4 controls the second telescopic member 42 to drive the code reader 3 to adjust the height, so that the height of the code reader 3 moves to be equal to m4 to obtain m5. At this time, the values of m3, m4, and m5 are equal, that is, the height of the single cigarette body 1 and the discharge port 21 and the distance between the code reader 3 and the upper end surface of the conveying device 25 are equal, thereby enabling the code reader 3 to face the side wall of the single cigarette body 1 output from the discharge port 21 to perform code recognition, thereby avoiding inaccurate recognition caused by the inconsistent height of the cigarette body 1 and the code reader 3;
[0035] The upper end of the feeding rack 2 is rotatably connected to a swing rod 28, and a first distance sensor 43 is connected to the swing rod 28. After the preliminary height detection of a single cigarette body 1 is completed, the swing rod 28 is rotated to drive the first distance sensor 43 to be offset from the top of the feeding rack 2, thereby not affecting the stacking of the cigarette bodies 1 into the feeding rack 2.
[0036] It also includes a memory component, which is used to store the height of a single cigarette body 1. The memory component includes a storage module 5 and an extraction module 51. The storage module 5 is electrically connected to the first distance sensor 43 and is used to record the height value of a single cigarette detected by the first distance sensor 43. The extraction module 51 is electrically connected to the controller 4 and is used to retrieve data from the storage module 5 according to the user terminal instruction, and drive the corresponding first telescopic member 41 and the second telescopic member 42 to move through the controller 4. After the height of a cigarette body 1 of a certain specification is measured, the values of m3, m4, and m5 are summarized as a group s1, and the value s1 is stored in the storage module 5 for maintenance. When it is necessary to encode and identify cigarette bodies 1 of other specifications, s2 is obtained by the same method as above, and before encoding and identifying cigarette bodies 1 of different specifications, s1 or s2 is extracted through the extraction module 51 under the operation instruction of the user terminal to control the movement of the first telescopic member 41 and the second telescopic member 42 of the controller 4. The first telescopic member 41, the second telescopic member 42 and the third telescopic member 6 can all be devices such as electric telescopic rods or electric push rods.
[0037] Further, such as Figure 2 As shown, a fixing frame 9 is provided at a position where the workbench 24 is opposite to the code reader 3, and an image acquisition device 91 is provided below the fixing frame 9. The image acquisition device 91 is used to acquire the image of the cigarette body 1, wherein the image acquisition device 91 can adopt a CCD camera or the like. While the code on the cigarette body 1 is read by the code reader 3, the information of the cigarette body 1 can be acquired by the image acquisition device 91 to identify whether the information of different types of cigarettes is consistent with the code data identified by the code reader 3.
[0038] Further, if Figure 2 As shown, the fixing frame 9 is provided with an RGB three-color light source 92 for performing camera compensation on the image acquisition device 91. Since the surface background pattern of the cigarette body 1 is relatively rich, different colors are distinguished and objects are identified through the RGB three-color light source 92, thereby helping the image acquisition device 91 to better understand and process images.
[0039] Further, such as Figure 5 As shown, an infrared filter 93 is provided on the lower end surface of the image acquisition device 91, and the infrared filter 93 filters out infrared rays with wavelengths exceeding the visible range of the human eye, thereby reducing the influence of infrared rays on imaging, improving the contrast and clarity of imaging, and further improving the image acquisition quality.
[0040] Further, such as Figure 1 as well as Figure 3As shown, a pressure sensor 8 electrically connected to the controller 4 is provided on the inner wall at the bottom of the feed rack 2, and an alarm 81 electrically connected to the controller 4 is provided on the outer wall of the feed rack 2. As the number of cigarette bodies 1 in the feed rack 2 decreases, the downward pressure on the pressure sensor 8 gradually decreases. When the pressure sensor 8 detects that the pressure value is less than the specified threshold, the signal is transmitted to the controller 4. The controller 4 turns on the alarm 81 to alert the personnel that the number of cigarette bodies 1 in the feed rack 2 is small and needs to be added in time.
[0041] Further, such as Figure 3 As shown, the upper end surface of the pressure sensor 8 is flush with the upper end surface of the conveying device 25, so that the cigarette body 1 conveyed from the pressure sensor 8 through the discharge port 21 can accurately fall on the conveying device 25. The conveying device 25 can be a device such as a conveyor belt, and the distance between the upper end surface of the conveying device 25 and the encoder reader 3 can be equal to the distance between the bottom end of the baffle plate 23 and the discharge port 21.
[0042] Further, such as Figure 2 As shown, the workbench 24 is provided with a correction component for correcting the cigarette body 1 entering the conveying device 25, the correction component includes two clamping plates 7 and a bidirectional screw rod 71 threadedly connected to the two clamping plates 7, the bidirectional screw rod 71 is rotatably connected to the workbench 24, and the end of the bidirectional screw rod 71 extending to the outside of the workbench 24 is provided with a motor 72, and a guide slide bar 73 is provided between the inner walls on both sides of the workbench 24, the guide slide bar 73 passes through the clamping plates 7 and is slidably connected to the clamping plates 7, when the photoelectric sensor 27 detects the appearance of the cigarette body 1 on the conveying device 25, it will transmit a signal to the controller 4, the controller 4 controls the motor 72 to drive the bidirectional screw rod 71 to rotate, so that the two clamping plates 7 move relative to each other, clamp the cigarette body 1 on the conveying device 25, so that its length direction can be kept parallel to the conveying device 25, and then move in the opposite direction to release the clamping of the cigarette body, so that the code reader 3 can more accurately identify the code on the side of the cigarette body 1.
[0043] like Figure 1-Figure 9As shown, the principle of the identification device for cigarette code detection provided in this embodiment is as follows: first, a single cigarette body 1 is placed in the feeding rack 2, and then the first distance sensor 43 detects the distance to the upper end of the single cigarette body 1, and then the height of the single cigarette body 1 can be calculated, and then stored and recorded through the storage module 5, and the remaining cigarette bodies 1 are stacked and placed in the feeding rack 2. After the controller 4 receives the data signal from the first sensor, it drives the baffle plate 23 to move through the first telescopic member 41, and detects the distance between the baffle plate 23 and the discharge port 21 according to the second distance sensor 44 on the baffle plate 23, so that it is equal to the height of the single cigarette body 1, and at the same time the second telescopic member 42 will drive the code reader 3 to move to the same height as the single cigarette body 1, so as to read the code on the side wall of the cigarette body 1. Then, through the movement of the third telescopic member 6, the single cigarette body 1 can be pushed out from the discharge port 21 and fall on the conveying device 25. When the photoelectric sensor 27 detects the cigarette body 1 on the conveying device 25, it will transmit a signal to the controller 4. The controller 4 will drive the third telescopic member 6 to retract and wait for the next cycle of pushing. The cigarette body 1 entering the conveying device 25 will be kept parallel to the conveying device 25 and move to the position of the code reader 3 under the action of the correction component, so as to more accurately identify and read the code on the cigarette body 1 with the code reader 3.
[0044] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.
[0045] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
[0046] The above description shows and describes several preferred embodiments of the present invention, but as mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field.
