[0001] The present invention relates to the technical field of cigarette processing, and in particular to a cigarette replenishing device and a method for detecting and associating a barcode in a cigarette pack. Background Art

[0002] In order to meet the needs of anti-counterfeiting, monopoly protection, and cigarette process tracking, it is necessary to print a QR code on the side of the small package of cigarettes, and the data content of the QR code of each pack of cigarettes is unique, and print the QR code on the cigarette pack box. When packaging the cigarette packs, it is necessary to ensure that the QR code information on the cigarette pack is associated with the QR code information on the box. Therefore, it is necessary to set up a code reader, industrial control computer, etc. on the packaging machine.

[0003] In the process of packing cigarettes, in order to ensure the quality, a part of the cigarette packs need to be extracted for inspection. The inspected cigarette packs are stored in the cigarette refiller of the F8 packaging machine and packaged into strips. However, the existing cigarette refiller used in the F8 packaging machine cannot read the QR code information on the cigarette packs in the cigarette refiller after the inspected cigarette packs are placed in the cigarette refiller, making the cigarette refiller of the F8 packaging machine unusable. If the QR code information of the cigarette packs in the cigarette refiller is read manually, the reading efficiency and accuracy cannot be guaranteed, and the accuracy of the association between the box and the strip cannot be guaranteed. Summary of the invention

[0004] The object of the present invention is to provide a cigarette replenishing device and a cigarette pack entry bar QR code detection and association method, which can accurately and quickly obtain the QR code information of the cigarette pack in the cigarette replenisher and ensure the accuracy of the box bar association.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0008] The verification mechanism includes a material level detection component, a code reading component, a verification code reader and an industrial computer. The material level detection component and the code reading component are arranged correspondingly to the smoke replenisher, the verification code reader is arranged correspondingly to the conveyor belt, and the material level detection component, the code reading component and the verification code reader are all connected to the industrial computer for communication;

[0009] Among them, the ten adjacent boxes of cigarette packs pushed onto the conveyor belt form a strip, the material level detection component can detect the number of the cigarette packs placed in the left cigarette replenishment channel and the right cigarette replenishment channel, the code reading component can read the QR codes of the cigarette packs in the left cigarette replenishment channel and the right cigarette replenishment channel through the corresponding windows, the verification code reader can read the QR codes of the cigarette packs pushed onto the conveyor belt, the industrial computer can associate the QR code information of the cigarette strip in the industrial computer with the QR code information of the ten adjacent boxes of cigarette packs pushed onto the conveyor belt, and can compare and verify the QR code information of the cigarette pack obtained by the code reading component with the QR code information of the cigarette pack obtained by the verification code reader.

[0010] As a further technical solution, the left smoke supply channel, the right smoke supply channel, the first window, and the second window all extend in the height direction, and the pusher assembly is arranged at the bottom of the smoke supply device.

[0011] As a further technical solution, the material level detection assembly includes a left material level detection member arranged corresponding to the left smoke supplement channel and a right material level detection member arranged corresponding to the right smoke supplement channel;

[0012] The left material level detection component and the right material level detection component both include height sensors, and are both located above the smoke replenisher, and / or, the left material level detection component and the right material level detection component both include weight sensors, and are both located in the pusher assembly.

[0013] As a further technical solution, the code reading component includes a plurality of reference code readers arranged at intervals along the height direction, and the plurality of reference code readers are arranged opposite to the first window. When the plurality of cigarette packs are placed in the cigarette replenisher, the plurality of reference code readers simultaneously read the QR code information of the cigarette packs in the corresponding code reading area.

[0014] As a further technical solution, the verification mechanism further includes a verification component, which includes a plurality of detectors arranged on the conveyor belt at intervals along the running direction of the conveyor belt, and the plurality of detectors are used to detect the number of cigarette packs conveyed on the conveyor belt, and are all connected to the industrial computer for communication;

[0015] When the plurality of detectors detect that there is no cigarette pack on the conveyor belt, the pusher assembly pushes the cigarette pack toward the conveyor belt (130), and when the material level detection assembly detects that there is no cigarette pack in the left cigarette replenishment channel, it replenishes cigarettes into the cigarette replenisher.

[0016] As a further technical solution, the verification mechanism also includes a fault prompt and two cigarette refilling end buttons, and the fault prompt and the two cigarette refilling end buttons are both communicatively connected to the industrial computer. After the cigarette refilling channel is completed, the corresponding cigarette refilling end button is pressed to enable the code reading component to read the QR code of the cigarette pack in the corresponding cigarette refilling channel through the corresponding window.

[0017] The method for associating the detection of a barcode in a cigarette package is applied to a cigarette replenishing device, and comprises the following steps:

[0018] S1, multiple cigarette packs are placed in the right cigarette replenishment channel, and then the cigarette replenishment end button corresponding to the right cigarette replenishment channel is pressed, and the reference code reader reads the QR code information of the multiple cigarette packs in the right cigarette replenishment channel through the first window and the second window in turn, and the right material level detection component detects the number of the multiple cigarette packs in the right cigarette replenishment channel, and transmits the number of the multiple cigarette packs in the right cigarette replenishment channel and the QR code information as reference information to the industrial computer;

[0019] S2, placing a plurality of cigarette packs in the left cigarette replenishment channel, and then pressing the cigarette replenishment end button corresponding to the left cigarette replenishment channel, the reference code reader reads the QR code information of the plurality of cigarette packs in the left cigarette replenishment channel through the first window, the left material level detection component detects the number of the plurality of cigarette packs in the left cigarette replenishment channel, and transmits the number of the plurality of cigarette packs in the left cigarette replenishment channel and the QR code information as reference information to the industrial computer;

[0020] S3, the pusher assembly pushes the cigarette packs toward the conveyor belt. The pusher assembly pushes the two cigarette packs at the bottom of the left cigarette supply channel and the two cigarette packs at the bottom of the right cigarette supply channel onto the conveyor belt in one push, so as to form two stacked pack groups on the conveyor belt;

[0021] S4, along the conveying direction of the conveyor belt, five adjacent stacked pack groups are one strip, and the verification code reader reads the two-dimensional code information of the cigarette packs in the five stacked pack groups and transmits it to the industrial computer, and associates the box strip with the two-dimensional code information of the corresponding cigarette strip in the industrial computer;

[0022] S5, along the conveying direction of the conveyor belt, the verification code reader reads the QR code information of the cigarette packs in the first group of stacked packs and the sixth group of stacked packs, and compares the QR code information with the reference information in the industrial computer. When the QR code information is the same as the reference information in the industrial computer, the box strip association is accurate.

[0023] As a further technical solution, the number of the cigarette packs placed in the left smoke supply channel is less than or equal to the number of the cigarette packs placed in the right smoke supply channel.

[0024] As a further technical solution, after the pusher assembly pushes the cigarette pack onto the conveyor belt, it also includes replenishing cigarettes, including:

[0025] When multiple inspectors all detect that there is no cigarette pack on the conveyor belt, the pusher assembly pushes the cigarette pack onto the conveyor belt. When the left material level detector detects that there is no cigarette pack in the left cigarette replenishment channel, the operator replenishes cigarettes into the cigarette replenisher.

[0026] As a further technical solution, before and after refilling the cigarette, a fault reminder alarm is also included. When the fault reminder alarms, the operator refills the cigarette. The situations in which the fault alarm is triggered include:

[0027] When adding cigarettes to the cigarette replenisher, the first button pressed is not the cigarette replenishment end button corresponding to the right cigarette replenishment channel;

[0028] and / or, when supplying cigarettes to the right cigarette supply channel, the left material level detection component detects that the cigarette pack is in the left cigarette supply channel;

[0029] And / or, the number of the cigarette packs placed in the left smoke supply channel is greater than the number of the cigarette packs placed in the right smoke supply channel.

[0030] Compared with the prior art, the cigarette replenishing device and the cigarette pack barcode detection and association method provided by the present invention have the following technical advantages:

[0031] 1. Since a first window is provided on the left cigarette replenishment channel, and a second window is provided on the right cigarette replenishment channel opposite to the first window, the material level detection component and the code reading component are provided corresponding to the cigarette replenisher, and the verification code reader is provided corresponding to the conveyor belt. Therefore, when it is necessary to pack the inspected and recovered cigarette packs into strips, firstly place a plurality of inspected and recovered cigarette packs in the right cigarette replenishment channel in sequence, and then the material level detection component senses and obtains the number of cigarette packs placed in the right cigarette replenishment channel, and at the same time, the code reading component obtains the QR code information of the plurality of cigarette packs placed in the right cigarette replenishment channel through the first window and the second window in sequence, and transmits the information as the reference information to the industrial computer; then place a plurality of inspected and recovered cigarette packs in the left cigarette replenishment channel, and then the material level detection component senses and obtains the number of cigarette packs placed in the left cigarette replenishment channel, and at the same time, the code reading component obtains the QR code information of the plurality of cigarette packs placed in the left cigarette replenishment channel through the first window, and transmits the information as the reference information to the industrial computer; so as to complete the acquisition of the QR code information of the plurality of cigarette packs in the cigarette replenisher. During the whole process, with the help of the material level detection component and the code reading component, through the corresponding window, the quantity information and QR code information of multiple cigarette packs in the right cigarette replenishment channel are first obtained, and then the quantity information and QR code information of multiple cigarette packs in the left cigarette replenishment channel are obtained, so as to ensure the efficiency and accuracy of obtaining the quantity information and QR code information of the cigarette packs in the cigarette replenisher; the quantity information obtained by the material level detection component and the number of QR code information obtained by the code reading component can be referenced to each other to further improve the accuracy. And when the pusher component pushes the cigarette packs in the cigarette replenisher onto the conveyor belt through the corresponding pack outlet, the verification code reader can read the QR code information of the cigarette packs pushed onto the conveyor belt and transmit it to the engineering machine, and the industrial computer associates the QR code information of the cigarette strips in the industrial computer with the QR code information of the adjacent ten boxes of cigarette packs pushed onto the conveyor belt, thereby realizing the box-strip association; at the same time, the industrial computer compares and verifies the QR code information of the cigarette packs obtained by the code reading component with the QR code information of the cigarette packs obtained by the verification code reader to ensure the accuracy of the box-strip association.

[0032] 2. When placing cigarette packs into the cigarette replenisher, the cigarette packs are placed in the right cigarette replenishment channel first, and then in the left cigarette replenishment channel. In this way, it can be avoided that the reference code reader cannot obtain the QR code information on multiple cigarette packs in the right cigarette replenishment channel because the cigarette packs in the left cigarette replenishment channel block the second window; after the cigarette replenishment in the corresponding cigarette replenishment channel is completed, the corresponding cigarette replenishment end button needs to be pressed, so as to avoid the situation where the replenishment sequence is wrong, and the reference code reader and the corresponding material level detection component can be triggered in time to obtain the QR code information and quantity information of multiple cigarette packs in the corresponding cigarette replenishment channel. Since the verification code reader can read the QR code information of the cigarette packs in the five stacked pack groups and transmit it to the industrial computer, the industrial computer associates the QR code information of the cigarette strips in the industrial computer with the QR code information of the cigarette packs in the five stacked pack groups, thereby completing the box strip association. After the association is completed, the accuracy of the association needs to be verified. Specifically, the verification code reader reads the QR code information of the cigarette packs in the first group of stacked packs and the sixth group of stacked packs and transmits it to the industrial computer. The industrial computer compares and verifies the QR code information with the QR code information of the cigarette packs obtained by the reference code reader. If the two information match, it indicates that the current box strip association of the five stacked pack groups is accurate. If it does not match, it is necessary to re-acquire and associate the information until the verification box strip association is accurate, thereby ensuring the accuracy of the box strip association.

[0039] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0040] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0041] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects before and after are in an "and / or" relationship.

[0042] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0043] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0044] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0045] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0046] Combination Figure 1 and Figure 2 As shown, the cigarette replenishing device provided in this embodiment is applied to the F8 type packaging machine, and is used to detect, associate and verify the cigarette packs that have been inspected and recovered by reading the QR code, so as to accurately and quickly obtain the QR code information of the cigarette packs in the cigarette replenisher 110 and ensure the accuracy of the box-strip association. In this embodiment, taking the arrangement of the code reading component on the left side of the smoke replenisher 110 as an example, the structure and working principle of the smoke replenisher are described, specifically: the smoke replenisher includes a smoke replenishing mechanism and a verification mechanism; the smoke replenishing mechanism includes the smoke replenisher 110, a pusher assembly 120 and a conveyor belt 130, the smoke replenisher 110 is provided with a left smoke replenishing channel 111 and a right smoke replenishing channel 112, each of which can accommodate multiple cigarette packs, a first window is arranged on the left smoke replenishing channel 111, a second window 1121 is arranged on the right smoke replenishing channel 112 opposite to the first window, and a pack outlet is arranged at the lower end of the left smoke replenishing channel 111 and the right smoke replenishing channel 112, and the pusher assembly 120 can push the cigarette pack placed in the smoke replenisher 110 to the conveyor belt 130 through the corresponding pack outlet.

[0047] The verification mechanism includes a material level detection component, a code reading component, a verification code reader 270 and an industrial computer 210. The material level detection component and the code reading component are arranged corresponding to the smoke replenisher 110, and the verification code reader 270 is arranged corresponding to the conveyor belt 130. The material level detection component, the code reading component and the verification code reader 270 are all communicatively connected with the industrial computer 210.

[0048] Among them, ten adjacent cigarette packs pushed onto the conveyor belt 130 form a strip, the material level detection component can detect the number of cigarette packs placed in the left cigarette replenishment channel 111 and the right cigarette replenishment channel 112, the code reading component can read the QR codes of the cigarette packs in the left cigarette replenishment channel 111 and the right cigarette replenishment channel 112 through the corresponding windows, the verification code reader 270 can read the QR code of the cigarette pack pushed onto the conveyor belt 130, the industrial computer 210 can associate the QR code information of the cigarette strip in the industrial computer 210 with the QR code information of the ten adjacent cigarette packs pushed onto the conveyor belt 130, and can compare and verify the QR code information of the cigarette pack obtained by the code reading component with the QR code information of the cigarette pack obtained by the verification code reader 270.

[0049] Since a first viewing window is provided on the left smoke supply channel 111 and a second viewing window 1121 is provided on the right smoke supply channel 112 opposite to the first viewing window, the material level detection component and the code reading component are provided corresponding to the smoke supply device 110 , and the verification code reader 270 is provided corresponding to the conveyor belt 130 . Therefore, when it is necessary to pack the inspected and recycled cigarette packs into strips, first place multiple inspected and recycled cigarette packs in the right cigarette replenishment channel 112 in turn, then the material level detection component senses and obtains the number of cigarette packs placed in the right cigarette replenishment channel 112, and at the same time, the code reading component obtains the QR code information of the multiple cigarette packs placed in the right cigarette replenishment channel 112 through the first window and the second window 1121 in turn, and transmits the information as the reference information to the industrial computer 210; thereafter, place multiple inspected and recycled cigarette packs in the left cigarette replenishment channel 111, then the material level detection component senses and obtains the number of cigarette packs placed in the left cigarette replenishment channel 111, and at the same time, the code reading component obtains the QR code information of the multiple cigarette packs placed in the left cigarette replenishment channel 111 through the first window, and transmits the information as the reference information to the industrial computer 210; so as to complete the acquisition of the QR code information of the multiple cigarette packs in the cigarette replenisher 110. During the whole process, with the help of the material level detection component and the code reading component, through the corresponding windows, the quantity information and QR code information of multiple cigarette packs in the right smoke replenishment channel 112 are first obtained, and then the quantity information and QR code information of multiple cigarette packs in the left smoke replenishment channel 111 are obtained, so as to ensure the efficiency and accuracy of obtaining the quantity information and QR code information of cigarette packs in the smoke replenisher 110; the quantity information obtained by the material level detection component and the number of QR code information obtained by the code reading component can be referenced to each other to further improve the accuracy. And when the pusher assembly 120 pushes the cigarette pack in the cigarette replenisher 110 onto the conveyor belt 130 through the corresponding pack outlet, the verification code reader 270 can read the QR code information of the cigarette pack pushed onto the conveyor belt 130 and transmit it to the engineering machine, and the industrial computer 210 associates the QR code information of the cigarette strips in the industrial computer 210 with the QR code information of the ten adjacent boxes of cigarette packs pushed onto the conveyor belt 130, thereby realizing the box-strip association; at the same time, the industrial computer 210 compares and verifies the QR code information of the cigarette pack obtained by the code reading assembly with the QR code information of the cigarette pack obtained by the verification code reader 270, so as to ensure the accuracy of the box-strip association.

[0050] Preferably, the left smoke supply channel 111 , the right smoke supply channel 112 , and the first window and the second window 1121 all extend in the height direction, and the pusher assembly 120 is disposed at the bottom of the smoke supply device 110 .

[0051] Combination Figure 1 As shown, in this embodiment, the smoke replenisher 110 includes a rear plate, a left partition, a middle partition and a right partition. The left partition, the middle partition and the right partition are fixedly connected to the rear plate in parallel and spaced from left to right, and are perpendicular to the rear plate. The left partition, the middle partition and part of the rear plate cooperate to form a left smoke replenishment channel 111, and the right partition, the middle partition and part of the rear plate cooperate to form a right smoke replenishment channel 112; the left partition uses a transparent glass slide to use the left partition as a whole as a first window, and the second window 1121 is set on the middle partition and extends in the height direction. In the process of replenishing smoke, the code reading component set on the left side of the smoke replenisher 110 can accurately and sequentially obtain the two-dimensional code information of multiple cigarette packs placed in the right smoke replenishment channel 112 and the two-dimensional code information of multiple cigarette packs placed in the left smoke replenishment channel 111. In the embodiment where the code reading component is arranged on the right side of the smoke replenisher 110, the right partition is made of a transparent glass sheet, and the right partition as a whole is used as the first window, and the second window 1121 is still arranged on the middle partition. In some other embodiments, the middle partition as a whole can also be directly set as the second window 1121, in which case the middle partition is made of a transparent glass sheet; or, a through slot extending in the height direction is opened on the left partition, and the through slot is used as the first window; the specific setting method is set according to actual needs and is not specifically limited here.

[0052] Since the left cigarette supplement channel 111 and the right cigarette supplement channel 112 both extend in the height direction, and the pusher assembly 120 is disposed at the bottom of the cigarette supplement device 110, when the pusher assembly 120 pushes the lower cigarette packs to the conveyor belt 130, the upper cigarette packs fall under their own gravity to ensure the continuity of the pusher assembly 120 pushing the cigarette packs to the conveyor belt 130. The pusher assembly 120 is not the technical focus of this embodiment, and can be set with reference to the prior art, and will not be described here.

[0053] A limiting plate parallel to the rear plate is provided at one end of the middle partition plate away from the rear plate, and the limiting plate extends in the left and right directions to limit the relative positions of multiple cigarette packs placed in the left smoke supply channel 111 and the right smoke supply channel 112, so as to prevent multiple cigarette packs from tipping forward and falling out of the smoke replenisher 110; at the same time, by providing the limiting plate, the side of the left smoke supply channel 111 and the right smoke supply channel 112 away from the rear plate is prevented from being closed, so that the operator can manually observe the cigarette packs in the left smoke supply channel 111 and the right smoke supply channel 112; the length of the limiting plate is less than that of the rear plate, so that a pack outlet is formed below the left smoke supply channel 111 and the right smoke supply channel 112 to facilitate the cigarette packs to be pushed out.

[0054] Preferably, the material level detection component includes a left material level detection component 221 arranged corresponding to the left smoke supply channel 111 and a right material level detection component 222 arranged corresponding to the right smoke supply channel 112. In this way, the speed and accuracy of obtaining the number of cigarette packs in the left smoke supply channel 111 and the right smoke supply channel 112 can be further improved by using the relatively independent left material level detection component 221 and the right material level detection component 222.

[0055] The left material level detection member 221 and the right material level detection member 222 both include height sensors and are both located above the smoke replenisher 110. The number of cigarette packs in the corresponding channel is obtained by obtaining the distance from the top layer of cigarette packs in the corresponding channel to the upper end outlet of the corresponding channel. Alternatively, the left material level detection member 221 and the right material level detection member 222 are both configured as weight sensors and are both located at the pusher assembly 120. The number of cigarette packs in the corresponding channel is obtained by sensing the total weight of the cigarette packs in the corresponding channel. The two sensors can be set one by one or both at the same time, and the technical effect of improving the speed and accuracy of obtaining the number of cigarette packs in the corresponding channel can be achieved. In order to further improve the speed at which the code reading component obtains the two-dimensional code information of multiple cigarette packs in the corresponding channel, the code reading component includes multiple reference code readers 230 spaced apart in the height direction, and the multiple reference code readers 230 are all arranged relative to the first window. When multiple cigarette packs are placed in the smoke replenisher 110, the multiple reference code readers 230 simultaneously read the two-dimensional code information of the cigarette packs in the corresponding code reading area.

[0056] In this embodiment, along the height direction, four reference code readers 230 are evenly spaced on the left side of the smoke replenishment device 110, and each reference code reader 230 can obtain the two-dimensional code information of five cigarette packs. Taking the acquisition of the two-dimensional code information of multiple cigarette packs placed in the left smoke replenishment channel 111 as an example, if the number of cigarette packs in the left smoke replenishment channel 111 is less than five, only the bottom reference code reader 230 works. If the number of cigarette packs in the left smoke replenishment channel 111 is ten to fifteen, except for the top reference code reader 230, the other three reference code readers 230 need to work. If the number of cigarette packs in the left smoke replenishment channel 111 is more than fifteen, all reference code readers 230 need to work. In this way, the speed and accuracy of obtaining the two-dimensional code information of multiple cigarette packs in the corresponding channel can be further improved. In other embodiments, the number of reference code readers 230 can be set to three, five, six, seven, etc. according to actual needs, and the number of cigarette packs whose two-dimensional code information can be obtained by each reference code reader 230 at the same time can be set to three, four, six, eight, etc. according to actual needs.

[0057] Preferably, the verification mechanism also includes an inspection component, which includes a plurality of inspectors 240 arranged at intervals on the conveyor belt 130 along the running direction of the conveyor belt 130, and the plurality of inspectors 240 are all used to detect the number of cigarette packs conveyed on the conveyor belt 130, and are all communicatively connected to the industrial computer 210; the industrial computer 210 detects the number of cigarette packs on the conveyor belt 130 by comparing the number of cigarette packs detected by the inspectors 240 with the current number of cigarette packs in the cigarette replenisher 110 to ensure that the cigarette packs do not fall off the conveyor belt 130 in the interval from the cigarette replenisher 110 to the inspection component, thereby ensuring the accuracy of the box strip association. At the same time, when multiple inspectors 240 all detect that there are no cigarette packs on the current conveyor belt 130, the pusher assembly 120 pushes the cigarette packs toward the conveyor belt 130. When the material level detection assembly detects that there are no cigarette packs in the left cigarette replenishment channel 111, the operator can replenish cigarettes into the cigarette replenisher 110, thereby avoiding the situation where the material level detection assembly obtains inaccurate number of cigarette packs in the corresponding channel due to premature replenishment of cigarettes, or the code reading assembly is unable to timely and accurately obtain the QR code information of multiple cigarette packs in the left cigarette replenishment channel 111 and the right cigarette replenishment channel 112, resulting in box strip association errors.

[0058] Preferably, the verification mechanism also includes a fault prompt component 250 and two cigarette refilling end buttons 260. The fault prompt component 250 and the two cigarette refilling end buttons 260 are both connected to the industrial computer 210 for communication. After the cigarette refilling channel is completed, the corresponding cigarette refilling end button 260 is pressed to enable the code reading component to read the QR code of the cigarette pack in the corresponding cigarette refilling channel through the corresponding window.

[0059] During the process of replenishing cigarettes, after the operator places the cigarette packs into the right cigarette replenishing channel 112, he presses the cigarette replenishing end button 260 corresponding to the right cigarette replenishing channel 112, and then triggers the right material level detection component 222 and the reference code reader 230 through the industrial computer 210 to obtain information on multiple cigarette packs in the right cigarette replenishing channel 112; then he places the cigarette packs into the left cigarette replenishing channel 111, and after placement is completed, he presses the cigarette replenishing end button 260 corresponding to the left cigarette replenishing channel 111, and then triggers the left material level detection component 221 and the reference code reader 230 through the industrial computer 210 to obtain information on multiple cigarette packs in the left cigarette replenishing channel 111. When refilling cigarettes, if the refilling cigarette end button 260 corresponding to the left refilling cigarette channel 111 is triggered first, or when refilling cigarettes, there are still multiple cigarette packs in the left refilling cigarette channel 111, or after refilling cigarettes, the number of cigarette packs in the left refilling cigarette channel 111 is greater than the number of cigarette packs placed in the right refilling cigarette channel 112, the fault prompting member 250 will issue an alarm prompt. When the operator receives the alarm prompt, he needs to refill cigarettes into the refilling cigarette device 110, so as to avoid the situation where the material level detection component obtains the inaccurate number of cigarette packs in the corresponding channel due to inaccurate refilling cigarette operation, and the code reading component cannot timely and accurately obtain the QR code information of multiple cigarette packs in the left refilling cigarette channel 111 and the right refilling cigarette channel 112, resulting in box strip association errors. The alarm prompt of the fault prompting member 250 can be set to a light prompt or a sound prompt according to actual needs, which is not specifically limited here.

[0060] A method for associating detection of a barcode in a cigarette package, applied to a cigarette replenishing device, comprises the following steps.

[0061] In the first step, a plurality of cigarette packs are placed in the right cigarette replenishment channel 112, and then the cigarette replenishment end button 260 corresponding to the right cigarette replenishment channel 112 is pressed. The reference code reader 230 reads the QR code information of the plurality of cigarette packs in the right cigarette replenishment channel 112 through the first window and the second window 1121 in turn. The right material level detection component 222 detects the number of the plurality of cigarette packs in the right cigarette replenishment channel 112, and transmits the number of the plurality of cigarette packs in the right cigarette replenishment channel 112 and the QR code information as reference information to the industrial computer 210.

[0062] In the second step, multiple cigarette packs are placed in the left cigarette replenishment channel 111, and then the cigarette replenishment end button 260 corresponding to the left cigarette replenishment channel 111 is pressed. The reference code reader 230 reads the QR code information of the multiple cigarette packs in the left cigarette replenishment channel 111 through the first window, and the left material level detection component 221 detects the number of the multiple cigarette packs in the left cigarette replenishment channel 111, and transmits the number of the multiple cigarette packs in the left cigarette replenishment channel 111 and the QR code information as reference information to the industrial computer 210.

[0063] In the third step, the pusher assembly 120 pushes the cigarette packs toward the conveyor belt 130 . The pusher assembly 120 pushes the two lowest cigarette packs in the left cigarette replenishment channel 111 and the two lowest cigarette packs in the right cigarette replenishment channel 112 onto the conveyor belt 130 at one time to form two stacked pack groups on the conveyor belt 130 .

[0064] In the fourth step, along the conveying direction of the conveyor belt 130, the five adjacent stacked pack groups are one strip, and the verification code reader 270 reads the QR code information of the cigarette packs in the five stacked pack groups and transmits it to the industrial computer 210, and associates the box strip with the corresponding QR code information of the cigarette strip in the industrial computer 210.

[0065] The fifth step is to verify that the code reader 270 reads the QR code information of the cigarette packs in the first and sixth stacked pack groups along the conveying direction of the conveyor belt 130, and compares the QR code information with the reference information in the industrial computer 210. When the QR code information is the same as the reference information in the industrial computer 210, the box strip association is accurate.

[0066] Through the above steps, when placing cigarette packs in the cigarette replenishment device 110, the cigarette packs are placed in the right cigarette replenishment channel 112 first, and then in the left cigarette replenishment channel 111. In this way, it can be avoided that the reference code reader 230 cannot obtain the QR code information on multiple cigarette packs in the right cigarette replenishment channel 112 because the cigarette packs in the left cigarette replenishment channel 111 block the second window 1121; after the cigarette replenishment in the corresponding cigarette replenishment channel is completed, the corresponding cigarette replenishment end button 260 needs to be pressed, so as to avoid the situation where the cigarette replenishment sequence is wrong, and the reference code reader 230 and the corresponding material level detection component can be triggered in time to obtain the QR code information and quantity information of multiple cigarette packs in the corresponding cigarette replenishment channel. Since the verification code reader 270 can read the QR code information of the cigarette packs in the five stacked pack groups and transmit it to the industrial computer 210, the industrial computer 210 associates the QR code information of the cigarette strips in the industrial computer 210 with the QR code information of the cigarette packs in the five stacked pack groups, thereby completing the box strip association. After the association is completed, the accuracy of the association needs to be verified, specifically: the verification code reader 270 reads the QR code information of the cigarette packs in the first group of stacked packs and the sixth group of stacked packs and transmits it to the industrial computer 210. The industrial computer 210 compares and verifies the QR code information with the QR code information of the cigarette packs obtained by the reference code reader 230. If the two information match, it means that the current box strip association of the five stacked pack groups is accurate. If it does not match, it is necessary to re-acquire and associate the information until the result of the verification box strip association is accurate, thereby ensuring the accuracy of the box strip association.

[0067] Preferably, the number of cigarette packs placed in the left cigarette supply channel 111 is less than or equal to the number of cigarette packs placed in the right cigarette supply channel 112. In this embodiment, the pusher assembly 120 pushes two stacked pack groups onto the conveyor belt 130 each time, and it is necessary to ensure that one group comes from the right cigarette supply channel 112 and the other group comes from the left cigarette supply channel 111. With such a configuration, in the process of the pusher assembly 120 pushing the cigarette packs onto the conveyor belt 130, it is avoided that there are no cigarette packs in the right cigarette supply channel 112, while there are still multiple cigarette packs remaining in the left cigarette supply channel 111, thereby avoiding that the pusher assembly 120 pushes only one stacked pack group onto the conveyor belt 130 in one pushing process, resulting in continuous cigarette packs from the left cigarette supply channel 111 appearing on the conveyor belt 130, thereby further ensuring the accuracy of the box strip association.

[0068] Preferably, after the pusher assembly 120 pushes the cigarette pack to the conveyor belt 130, it also includes replenishing cigarettes, including: the multiple detectors 240 all detect that there is no cigarette pack on the current conveyor belt 130, and the pusher assembly 120 pushes the cigarette pack to the conveyor belt 130, and when the left material level detection member 221 detects that the number of cigarette packs in the left replenishing channel 111 is zero, the operator can replenish cigarettes into the replenishing device 110. In this way, it is avoided that the operator replenishes cigarettes in advance and causes the box strip association error, and at the same time, it is avoided that the overall processing efficiency is reduced due to the operator not replenishing cigarettes for a long time.

[0069] In order to avoid the situation where the material level detection component obtains inaccurate number of cigarette packs in the corresponding channel due to inaccurate operation during the cigarette replenishment process, or the code reading component is unable to timely and accurately obtain the QR code information of multiple cigarette packs in the left cigarette replenishment channel 111 and the right cigarette replenishment channel 112, resulting in box strip association errors, in this embodiment, before and after replenishing cigarettes, a fault prompt component 250 alarm reminder is also included. When the fault prompt component 250 reminds, the operator replenishes cigarettes again. The situations that trigger the fault alarm include: when replenishing cigarettes into the cigarette replenisher 110, the first button pressed is not the cigarette replenishment end button 260 corresponding to the right cigarette replenishment channel 112; and / or, when replenishing cigarettes into the right cigarette replenishment channel 112, the left material level detection component 221 detects that there are cigarette packs in the left cigarette replenishment channel 111; and / or, the number of cigarette packs placed in the left cigarette replenishment channel 111 is greater than the number of cigarette packs placed in the right cigarette replenishment channel 112.
