Description

Technical Field

[0001] The invention relates to the field of cigarette manufacturing, and in particular to a cigarette box associated information verification and rejection system. Background Art

[0002] The tobacco industry has begun to fully adopt the "box-condition-piece" correlation technology to improve the tracking and verification capabilities of cigarettes. When consumers buy cigarettes, they scan the QR code on the box, strip, and piece to monitor the entire production process of the product in real time, including raw material procurement, production and manufacturing, transportation and storage, until the product reaches the hands of the consumer. This technology makes tracking quality issues more accurate. At present, the "box-condition-piece" correlation technology has become the main means to confirm the authenticity and quality traceability of tobacco products. Therefore, the high accuracy coverage of the QR code is particularly important.

[0003] The existing cigarette box verification method only verifies at the verification position and does not have a rejection function. When a cigarette box with a verification error occurs, it will cause the sealing machine line to stop, affecting the operation of the entire production line.

[0004] To elaborate, the current verification of the "box-condition-item" association information through the scan camera of the verification position can accurately identify the information of the erroneous QR code, but when an error occurs, the cigarette box needs to be manually found and manually removed; and when necessary, it is necessary to stop the search, which affects the operation of the entire production line. Therefore, the existing technical solution has at least the following deficiencies: it does not have the function of automatically removing the erroneous cigarette boxes, and the erroneous cigarette boxes need to be manually searched and removed. Based on manual search and removal, relevant trained and experienced personnel are required, and the workload of the operators will be increased. At the same time, it is also impossible to eliminate missed inspections and wrong inspections caused by manual operation. Summary of the invention

[0005] In view of the above, the present invention aims to provide a cigarette box associated information verification and rejection system, which can realize the non-stop rejection of incorrect two-dimensional codes in cigarette boxes.

[0006] The technical solution adopted by the present invention is as follows:

[0007] The present invention provides a cigarette box associated information verification and rejection system, which includes: an industrial computer, a rejection device, a first sensor, a second sensor, a rejection cigarette box buffer area, a scanning terminal and two conveying chains;

[0008] Wherein, the rejecting device is arranged between the two conveying chains and placed below the conveying chains, and the rejecting cigarette box buffer area is arranged on one side of one of the conveying chains and corresponds to the position of the rejecting device;

[0009] The first sensor and the scanning terminal are arranged in front of one side of the conveying chain, and the first sensor is used to detect the cigarette box and trigger the scanning terminal to read the QR code;

[0010] The second sensor is arranged on one side of the conveying chain and corresponds to the position of the rejecting device, and is used to detect abnormal cigarette boxes and trigger the rejecting device to operate;

[0011] The running direction of the rejection belt provided on the rejection device is perpendicular to the running direction of the conveying chain. The rejection device transports the abnormal cigarette box from the rejection port on one side of the conveying chain and close to the rejection cigarette box buffer area to the rejection cigarette box buffer area through the lifting action and the running of the rejection belt.

[0012] The rejecting device, the first sensor, the second sensor, and the scanning terminal are respectively connected to the industrial control machine by electrical signals.

[0013] In at least one possible implementation, the rejecting device includes: a PLC controller, a lifting cylinder, a lifting platform, a servo motor, a rotating roller, and a toothed belt;

[0014] The servo motor is arranged on the lifting platform, the servo motor drives the rotating roller to operate through the toothed belt, and the rejecting belt is connected to the rotating roller;

[0015] The lifting cylinder is used to support and lift the lifting platform, and the PLC controller is respectively connected with the servo motor, the lifting cylinder and the industrial control electromechanical signal.

[0016] In at least one possible implementation, a third sensor connected to the industrial control electromechanical signal is arranged on one side of the conveying chain and in front of the rejection device, and the third sensor cooperates with the second sensor to provide an in-place signal of the abnormal cigarette box, and the in-place signal indicates that the abnormal cigarette box is facing the rejection port.

[0017] In at least one possible implementation, a fourth sensor connected to the industrial control machine electrical signal is arranged on one side of the conveying chain and near the rejection port, and the fourth sensor is used to provide a detachment signal of the abnormal cigarette box, and the detachment signal indicates that the abnormal cigarette box detaches from the conveying chain and enters the rejection cigarette box buffer area.

[0018] In at least one possible implementation manner, a plurality of rollers are arranged on the reject cigarette box buffer area, and the rollers are used to assist in conveying abnormal cigarette boxes in the reject cigarette box buffer area.

[0019] In at least one possible implementation, the industrial computer includes an industrial touch screen arranged on one side of the conveying chain.

[0020] Compared with the prior art, the main design concept of the present invention is to add a device for automatic verification and rejection of the two-dimensional code of cigarette boxes on the cigarette box conveying production line, detect the quality inspection data and abnormal conditions of each cigarette box in real time, verify and reject the cigarette boxes with incorrect "box-condition-piece" association information, and realize the function of automatic rejection. Specifically, it includes an industrial computer, a rejection device, a first sensor, a second sensor, a buffer area for rejecting cigarette boxes, a scanning terminal and two conveying chains. The first sensor triggers the scanning terminal to read the code, and after the industrial computer verifies the abnormality, the rejection device is activated; when the second sensor detects the abnormal cigarette box, the rejection device lifts it and changes the conveying direction, and sends the abnormal cigarette box into the buffer area, and then the rejection device is reset to wait for the next abnormality detection. The present invention can significantly reduce the workload of manual verification and rejection operations, and reduce the number of shutdowns of the conveying production line, thereby greatly improving the equipment operation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described below with reference to the accompanying drawings, in which:

[0023] Figure 2 An internal side view of a rejection device provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0025] The present invention proposes an embodiment of a cigarette box associated information verification and rejection system. Specifically, Figure 1 As shown, it includes: an industrial computer 1, a rejection device 2, a first sensor 4, a second sensor 6, a rejection smoke box buffer area 8, a scanning dock 10 and two conveying chains 11.

[0026] The rejecting device 2 is arranged between the two conveying chains 11 and placed below the conveying chains 11, and the rejecting cigarette box buffer area 8 is arranged on one side of the conveying chain 11 and corresponds to the position of the rejecting device 2;

[0027] The first sensor 4 and the scanning terminal 10 are arranged in front of one side of the conveying chain 11 (relative to the running direction of the conveying chain 11), and the first sensor 4 is used to detect the cigarette box and trigger the scanning terminal 10 to read the QR code;

[0028] The second sensor 6 is arranged on one side of the conveying chain 11 and corresponds to the position of the rejecting device 2, and is used to detect abnormal cigarette boxes and trigger the rejecting device 2 to work;

[0029] The running direction of the rejection belt 3 provided on the rejection device 2 is perpendicular to the running direction of the conveying chain 11. The rejection device 2 transports the abnormal cigarette box from the rejection port 12 to the rejection cigarette box buffer area 8 through the lifting action and the operation of the rejection belt 3. It should be added here that by setting up the buffer area, multiple erroneous cigarette boxes can be cached, reducing the urgency of handling erroneous cigarette boxes.

[0030] The rejecting device 2 , the first sensor 4 , the second sensor 6 , and the scanning terminal 10 are respectively connected to the industrial computer 1 with electrical signals.

[0031] Combination Figure 2 As shown in some preferred embodiments, the rejection device 2 may specifically include: a PLC controller 21, a lifting cylinder 22, a lifting platform 23, a servo motor 24, a rotating roller 25 and a toothed belt 26; the servo motor 24 is deployed on the lifting platform 23, the servo motor 24 drives the rotating roller 25 to operate through the toothed belt 26, and the rejection belt 3 is connected to the rotating roller 25; the lifting cylinder 22 is used to support and lift the lifting platform 23, and the PLC controller 21 is electrically connected to the servo motor 24, the lifting cylinder 22 (and the solenoid valve matched therewith) and the industrial computer 1 respectively.

[0032] According to this concept, that is, when an abnormal cigarette box is detected by the industrial computer 1 according to mature scanning and comparison technology, the rejection device 2 is triggered to lift the abnormal cigarette box in a lifting manner and change the conveying direction, and the cigarette box is transferred to the rejection cigarette box buffer area 8; and after completing the task of transferring the abnormal cigarette box, the rejection device 2 needs to be lowered in time to ensure the normal transportation of other cigarette boxes on the conveying chain 11.

[0033] Therefore, in order to reliably achieve stable rejection of abnormal cigarette boxes and reliable transport and reset, the following two preferred solutions can also be configured in other embodiments of the present invention:

[0034] First, a third sensor 5 connected to the industrial computer 1 by electrical signals is arranged on one side of the conveying chain 11 and in front of the rejecting device 2 (relative to the running direction of the conveying chain 11). The third sensor 5 cooperates with the second sensor 6 to provide an abnormal smoke box arrival signal, and the arrival signal indicates that the abnormal smoke box is facing the rejecting port 12. In actual operation, the second sensor 6 may detect the abnormal smoke box, and the third sensor 5 may feedback that the abnormal smoke box is out of its detection range. Therefore, the positions of the second and third sensors may be set according to the actual running speed, smoke box specifications, rejecting port size, etc.

[0035] Secondly, a fourth sensor 7 connected to the industrial computer 1 by electrical signals is arranged on one side of the conveying chain 11 and near the rejection port 12. The fourth sensor 7 is used to provide an abnormal cigarette box detachment signal, and the detachment signal indicates that the abnormal cigarette box detaches from the conveying chain 11 and enters the rejection cigarette box buffer area 8.

[0036] Further based on this concept, a plurality of rollers 9 are arranged on the reject cigarette box buffer area 8 to assist in conveying abnormal cigarette boxes in the reject cigarette box buffer area 8 .

[0037] Finally, it can be added that the aforementioned industrial computer 1 may preferably refer to an industrial touch screen arranged on one side of the conveying chain 11, and the present invention does not limit or elaborate on this.

[0038] Based on the above embodiments, the working mechanism of the present invention can be schematically introduced as follows: when the cigarette box runs along the conveying chain to the first sensor, the scanning terminal is triggered to scan the code. The industrial computer receives the code scanning signal and verifies the "box-condition-item" association information of the cigarette box. If the verification fails, the industrial computer can send a rejection signal to the rejection device; at this time, it can be understood that the rejection device is in a standby state. When the abnormal cigarette box runs to the second sensor and leaves the third sensor at the same time, it indicates that the abnormal cigarette box is in place. The PLC controller of the rejection device controls the lifting cylinder to lift, drives the lifting platform to move upward, and makes the rejection roller move upward and rotate. The abnormal cigarette box is lifted and transported to the rejection buffer area by the rotation of the rejection belt.

[0039] When the abnormal cigarette box enters the rejection buffer area and is out of the detection range of the fourth sensor at the rejection port by the action of the roller, it indicates that the abnormal cigarette box has entered the buffer area as a whole. At this time, the rejection device completes its task and is driven down by its PLC controller, and the rejection belt on it also stops running. Through the above process, the automatic verification of the "box-condition-piece" association information of the cigarette box and the automatic rejection task are completed.

[0040] In summary, the main design concept of the present invention is to add an automatic verification and rejection device for the two-dimensional code of cigarette boxes to the cigarette box conveying production line, detect the quality inspection data and abnormal conditions of each cigarette box in real time, verify and reject the cigarette boxes with incorrect "box-condition-piece" association information, and realize the function of automatic rejection. Specifically, it includes an industrial computer, a rejection device, a first sensor, a second sensor, a rejection cigarette box buffer area, a scanning terminal and two conveying chains. The first sensor triggers the scanning terminal to read the code, and the rejection device is activated after the industrial computer verifies the abnormality; when the second sensor detects the abnormal cigarette box, the rejection device lifts it and changes the conveying direction, and sends the abnormal cigarette box into the buffer zone, and then the rejection device is reset to wait for the next abnormality detection. The present invention can significantly reduce the workload of manual verification and rejection operations, and reduce the number of shutdowns of the conveying production line, thereby greatly improving the equipment operation efficiency.

[0041] If the expressions expressing orientation are mentioned in the embodiments of the present invention, they are relative concepts based on the embodiments. In addition, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent the existence of A alone, the existence of A and B at the same time, and the existence of B alone. Among them, A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" and similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can be represented by: a, b, c, a and b, a and c, b and c, or a and b and c, wherein a, b, c can be single or multiple.

[0042] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred methods can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the present invention is not limited to the scope of implementation shown in the drawings, and all changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the specification and drawings, should be within the protection scope of the present invention.
