Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigarette production technology, and in particular to an automatic rejection system for failed QR code association of cigarette cartons and a carton sealing machine. Background Technology
[0002] In the cigarette production process, after cigarettes are packaged in boxes, they need to be packaged into cartons and cases, requiring that the QR codes on the cartons be linked to the QR codes on the cases. Specifically, after the cases leave the sealing machine, they enter a conveyor belt where the QR codes are read and linked. Cases of cigarettes are transported one by one on the conveyor belt. If the QR code link for a case fails to connect, that case of cigarettes must be removed from the conveyor belt to prevent unlinked cases from entering the market.
[0003] Some existing cigarette production lines include push rods and branch conveyor belts. The push rods are located at the edge of the main conveyor belt, and the extension and retraction direction of the push rods is perpendicular to the conveying direction of the main conveyor belt; the conveying direction of the branch conveyor belts is consistent with the extension and retraction direction of the push rods.
[0004] When a package of cigarettes with a failed QR code association appears on the main conveyor belt, a pusher extends and directly pushes the package laterally onto a branch conveyor belt, thus achieving online rejection of the failed association. To ensure a smoother transport process, there is a certain amount of friction between the cigarette package and the main conveyor belt. When the pusher laterally pushes the package away from the main conveyor belt, the outer packaging of the cigarettes will experience significant friction with the surface of the main conveyor belt, potentially damaging the outer packaging and / or the surface of the main conveyor belt, increasing losses and costs. Utility Model Content
[0005] The purpose of this invention is to propose an automatic rejection system and sealing machine for cigarette packs with failed QR code association, which solves the problem that existing rejection devices will damage the outer packaging of cigarette packs and reduces costs.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] An automatic rejection system for failed QR code association of cigarettes includes: a main conveyor belt assembly for transporting cigarettes; a rejection conveyor belt assembly having a standby position below the main conveyor belt assembly and a working position above the main conveyor belt assembly, the rejection conveyor belt assembly being movable between the standby position and the working position, the rejection conveyor belt assembly including a rejection conveyor belt body and rollers, the rejection conveyor belt assembly being able to move the cigarettes on the main conveyor belt assembly to the rejection conveyor belt body via the rollers when in the working position; and a QR code reading component for reading the QR code on the cigarettes to determine whether the QR code association has failed.
[0008] In one preferred embodiment, the QR code reading component includes: a QR code industrial control computer, used to determine whether the QR code association has failed, and when the QR code association fails, it can send a signal to the rejection conveyor assembly to move the cigarette pack on the main conveyor assembly to the rejection conveyor assembly; a cigarette pack barcode reader, used to identify the QR code on the cigarette pack and send the identification result to the QR code industrial control computer for the industrial control computer to determine whether the QR code association has failed; and a QR code PLC, used to send a signal to the cigarette pack barcode reader to cause the cigarette pack barcode reader to start identifying the QR code on the cigarette pack.
[0009] In one preferred embodiment, the automatic rejection system for failed QR code association of cigarettes further includes a first detection device. When the first detection device detects that a cigarette is passing by on the main conveyor belt assembly, it can send a signal to the QR code PLC, so that the QR code PLC sends a signal to the cigarette reader to start recognizing the QR code.
[0010] In one preferred embodiment, the first detection device is a photoelectric switch.

[0016] On the other hand, the present invention adopts the following technical solution:
[0017] Carton sealing machine, including the aforementioned automatic rejection system for failed QR code association of cigarette packs.
[0018] The automatic rejection system for failed QR code association of cigarettes disclosed in this utility model can use rollers to move cigarettes with failed QR code associations from the main conveyor belt assembly to the rejection conveyor belt assembly.

[0019] The carton sealing machine disclosed in this utility model includes the above-mentioned automatic rejection system for failed QR code association of cigarette packs. It can quickly, accurately and efficiently remove cigarette packs with failed QR code association from the main conveyor belt assembly online.

[0030] This embodiment discloses an automatic rejection system for failed QR code association of cigarettes and a carton sealing machine including the automatic rejection system. The carton sealing machine can pack cigarettes into a carton to form a package of cigarettes. The automatic rejection system is set at the outlet end of the main body of the carton sealing machine and can remove packages of cigarettes that fail to associate with QR codes from the logistics line, thus preventing successfully associated packages of cigarettes from being mixed with those that fail to associate.
[0031] like Figure 1 and Figure 2 As shown, the automatic rejection system for failed QR code association of cigarette packs includes a main conveyor belt assembly 1, a rejection conveyor belt assembly 5, and a QR code reading assembly. The main conveyor belt assembly 1 is used to transport cigarette packs 7 that come out from the main outlet of the sealing machine. The QR code reading assembly is used to read the QR code on the cigarette pack 7 to determine whether the QR code association on the cigarette pack 7 has failed.
[0032] The rejection conveyor assembly 5 includes a rejection conveyor body 51 and rollers 52. The rejection conveyor body 51 is located next to the main conveyor assembly 1. The height of the rollers on the rejection conveyor body 51 can be equal to the height of the rollers on the main conveyor assembly 1, so there is no height difference when the cigarette item 7 is transferred from the main conveyor assembly 1 to the rejection conveyor body 51, making the transfer smoother. The rejection conveyor body 51 can also move up and down to receive the cigarette items 7 rejected from the main conveyor assembly 1.
[0033] Rollers 52 are positioned below the main conveyor belt assembly 1, with each roller 52 located between two adjacent rollers on the main conveyor belt assembly 1. When a roller 52 rises, it passes through the gap between two adjacent rollers on the main conveyor belt assembly 1, causing the apex of the roller 52 to be higher than the apex of the roller. The component 7, originally located on the roller, can then be positioned on the roller 52. The removal conveyor belt body 51 can form an integral structure with the rollers 52. When the rollers 52 move up and down, the removal conveyor belt body 51 also moves up and down synchronously. The overall structure has high strength and is easy to control.
[0034] When roller 52 is below the main conveyor belt assembly 1, the rejection conveyor belt assembly 5 is in the standby position; when roller 52 rises until its apex is higher than the apex of the roller, the rejection conveyor belt assembly 5 is in the working position. The raising and lowering of roller 52 enables the rejection conveyor belt assembly 5 to move between the standby position and the working position.
[0035] When the QR code association on a cigarette item 7 fails, the rejection conveyor belt assembly 5 is in the working position, the roller 52 lifts the cigarette item 7 located on the main conveyor belt assembly 1 with the failed QR code association and rotates it, the cigarette item 7 moves in the direction of the rotation of the roller 52 until it is moved to the rejection conveyor belt assembly 5, realizing the online rejection of the cigarette item 7 with the failed QR code association.
[0036] The roller 52 and the cigarette pack 7 experience rolling friction. When the roller 52 transfers the cigarette pack 7 from the main conveyor belt assembly 1 to the rejection conveyor body 51, it does not damage the outer surface of the cigarette pack 7, nor does it damage the surface of the main conveyor belt assembly 1, thus extending the service life of the main conveyor belt assembly 1. After resolving the QR code association failure issue, the cigarette pack 7 can still continue to be processed and sold normally, improving the yield and reducing costs. This automatic rejection system can quickly, accurately, and efficiently remove cigarette packs 7 with failed QR code associations from the main conveyor belt assembly 1 online. It prevents the accumulation and blockage of cigarette packs 7 on the main conveyor belt assembly 1 due to failed QR code associations, and can remove cigarette packs with failed QR code associations without stopping the machine. This makes the production process smoother and improves product quality control and production efficiency.
[0037] The specific structure of the QR code reading component is not limited, as long as it can read the QR code on the cigarette pack 7 and determine whether the QR code association has failed. In this embodiment, the QR code reading component includes a QR code industrial control computer, a cigarette pack reader 4, and a QR code PLC (Programmable Logic Controller). The QR code industrial control computer is used to determine whether the QR code association has failed; the bracket 2 spans above the main conveyor belt assembly 1, and the cigarette pack reader 4, mounted on the bracket 2, is used to identify the QR code on the cigarette pack 7 and send the identification result to the QR code industrial control computer for determining whether the QR code association has failed; the QR code PLC is used to send a photo signal to the cigarette pack reader 4, causing the cigarette pack reader 4 to start identifying the QR code on the cigarette pack 7.
[0038] In this embodiment, the industrial control computer (i.e., industrial control computer) can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program, thereby controlling the cigarette code reader 4 to realize its function.
[0039] The specific method used by the QR code industrial control computer to determine whether the QR code association has failed is not limited. In this embodiment, after receiving the code segment information returned by the cigarette reader 4, the QR code industrial control computer associates the code segment of the cigarette pack with the code segment of the cigarette pack according to the association algorithm. It is understood that the specific method of the association algorithm is not limited, and any existing association algorithm that can associate the code segment of the cigarette pack with the code segment of the cigarette pack can be used.
[0040] In this embodiment, the rejection conveyor assembly 5 also includes a rejection conveyor PLC, which is connected to the QR code reading component. When it is determined that the QR code association fails, the QR code industrial control computer sends a signal to the rejection conveyor assembly 5. After receiving the signal, the rejection conveyor PLC can control the roller 52 to rise, so as to move the cigarette item 7 on the main conveyor assembly 1 to the rejection conveyor assembly 5.
[0041] Based on the above structure, the main conveyor belt assembly 1 includes the main conveyor belt body and the main conveyor belt PLC. The main conveyor belt PLC can control the start and stop of the main conveyor belt body. The rejection conveyor belt PLC and the main conveyor belt PLC can be independent of each other, and the control program is simple; the rejection conveyor belt PLC and the main conveyor belt PLC can also be integrated into a single conveyor belt PLC, which controls the main conveyor belt body and the rejection conveyor belt body 51 respectively. This results in a small overall size and low cost.
[0042] In order to identify all cigarette packs 7 on the main conveyor belt assembly 1, this embodiment of the automatic rejection system for failed QR code association of cigarette packs also includes a first detection device 3 mounted on the bracket 2. When the first detection device 3 detects that a cigarette pack 7 is passing by on the main conveyor belt assembly 1, it sends a signal to the QR code PLC. After receiving the signal, the QR code PLC sends a photo signal to the cigarette pack reader 4 to start recognizing the QR code, thus preventing any cigarette packs 7 from being missed and their QR codes from not being recognized.
[0043] The first detection device 3 can be, but is not limited to, a photoelectric switch; other devices capable of detecting the passage of the smoke item 7 can also be used. When the first detection device 3 is a photoelectric switch, once it detects the passage of the smoke item 7 on the main conveyor belt assembly 1, the first detection device 3 can send a trigger signal to the QR code PLC, resulting in high detection accuracy.
[0044] Based on the above structure, the automatic rejection system for failed QR code association of cigarette packs also includes a second detection device 6. The second detection device 6 is connected to the rejection conveyor assembly 5. When the rejection conveyor assembly 5 learns from the QR code PLC that there are cigarette packs 7 with failed QR code association on the main conveyor assembly 1 and receives the signal from the second detection device 6, the rejection conveyor assembly 5 can enter the working position and reject the cigarette packs 7 with failed QR code association from the main conveyor assembly 1 online.
[0045] The second detection device 6 can be, but is not limited to, a photoelectric switch; other devices capable of detecting the passage of the smoke 7 can also be used.
[0046] The specific structure of the main conveyor belt body of the main conveyor belt assembly 1 is not limited, as long as it can transport the cigarette pack 7 from the outlet end of the sealing machine body to the designated position. In this embodiment, the main conveyor belt body has a segmented structure, which is easy to process and can be assembled according to the shape and size of the work site, adapting to the needs of various sites and making it more convenient to use.
[0047] The following describes the working steps of this automatic rejection system, taking an example where both the first detection device 3 and the second detection device 6 are photoelectric switches, and the rejection conveyor PLC and the main conveyor PLC are integrated into a single conveyor PLC. When the first photoelectric switch detects a cigarette pack 7 passing on the main conveyor belt assembly 1, it sends a signal to the QR code PLC. The QR code PLC receives the trigger signal from the first photoelectric switch via I0.0 and outputs a signal to the cigarette pack reader 4 via Q0.0. The cigarette pack reader 4 receives the image capture signal from the QR code PLC, takes an image, identifies the QR code on the cigarette pack 7 in the captured image, and transmits it to the QR code industrial control computer via the network port. The QR code industrial control computer receives the code segment information returned by the cigarette pack reader 4 and associates the cigarette pack code segment with the cigarette pack code segment according to the association algorithm. When an association failure occurs, the QR code industrial control computer sends an association failure signal to the QR code PLC via a PCI card. After receiving the rejection signal sent by the QR code industrial control computer, the QR code PLC's input signal I0.1 outputs a high level to the conveyor PLC via its output signal Q0.2. The conveyor belt PLC controls the segmented main conveyor belt to operate by outputting a high level through Q0.1. When it receives the QR code rejection signal from I0.1, it controls the rejection conveyor belt to rise by outputting a low level through Q0.3. When I0.0 receives the second photoelectric switch signal, the conveyor belt PLC continues to maintain the rising of the rejection conveyor belt. When the signal from the second photoelectric switch disappears, the conveyor belt PLC controls the rejection conveyor belt to fall.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
