Description

Technical Field

[0001] The invention relates to the field of cigarette manufacturing, and in particular to a movable medium-sized cigarette box and a two-dimensional code information association system for each cigarette. Background Art

[0002] At present, the tobacco industry promotes the unified application of the "box-strip-piece" association management system (hereinafter referred to as the management system) for cigarette QR codes. All small cigarette boxes, strip boxes, and cigarette pieces used to package and transport cigarettes (hereinafter referred to as cigarette boxes) must be printed or affixed with industry QR codes. Among them, small boxes and strip boxes are printed with QR codes (there is only one QR code on each small box and strip box for subsequent association), and a QR code is affixed to the cigarette box. During the cigarette production process, the management system will associate the QR code on the cigarette strip with the QR code information on the 10 small boxes packed in the cigarette strip, and then associate the QR code on the cigarette box with the QR code on the 50 / 25 cigarette strips in the box during the packing process.

[0003] In the actual production process, the "box-bar-piece" QR code association of cigarettes will be automatically completed on the production equipment and packaging equipment as the production process proceeds, but there are still situations where manual association is required, such as the final stage of production, when quality problems occur and rework occurs, etc. Manual association may be required. Manual association requires the use of a dedicated PDA to scan the QR code on the cigarette bars one by one for association, which costs a lot of manpower and time, and is labor-intensive. Summary of the invention

[0004] In view of the above, the present invention aims to provide a movable medium-sized cigarette box and a cigarette QR code information association system to solve the above-mentioned technical problems.

[0005] The technical solution adopted by the present invention is as follows:

[0006] The present invention provides a movable medium-sized cigarette box and piece cigarette two-dimensional code information association system, which comprises: a conveyor belt with a plurality of rollers, a gantry frame arranged across the conveyor belt, a fixed bracket connected to the gantry frame and located on one side of the gantry frame is arranged on the side of the conveyor belt, and a universal wheel with a brake is installed under the conveyor belt;

[0007] The first scanning terminal is arranged on the other side of the gantry, and is used to read the QR code on the open cigarette box input from the discharge position of the conveyor belt; an L-shaped bracket with adjustable angle is connected to the crossbeam of the gantry, and two second scanning terminals are installed at the lower end of the L-shaped bracket, and are used to read the QR code on the strip box in the cigarette box;

[0008] A first diffuse reflection type photoelectric switch installed on the same side of the first scanning terminal is used to detect the input cigarette box and trigger the first scanning terminal to work; and a plurality of second diffuse reflection type photoelectric switches are installed in parallel at equal distances on the fixed bracket to detect the conveying position of the cigarette box and trigger the second scanning terminal to work respectively;

[0021] Furthermore, by setting a reset button, the association failure information can be easily and quickly cleared, allowing the system to recover and associate again. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] 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 1 A schematic diagram of a system for associating a movable medium-sized cigarette carton with a cigarette QR code provided by an embodiment of the present invention;

[0024] Figure 2 A side view of a conveyor belt provided in accordance with an embodiment of the present invention. DETAILED DESCRIPTION

[0025] 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.

[0026] The present invention proposes an embodiment of a movable medium-sized cigarette box and a cigarette QR code information association system. Specifically, Figure 1 As shown, it includes: a conveyor belt 9 with a plurality of rollers 8, a gantry 4 straddling the conveyor belt 9, and a fixed bracket 17 connected to the gantry 4 and located on one side of the gantry 4 is provided on the side of the conveyor belt 9;

[0027] The first scanning terminal 7 is arranged on the other side of the gantry 4, and is used to read the QR code on the open cigarette box input from the discharge position of the conveyor belt; an L-shaped bracket 5 with an adjustable angle is connected to the crossbeam of the gantry 4, and two second scanning terminals 19 are installed at the lower end of the L-shaped bracket 5, and are used to read the QR code on the cigarette box in the cigarette box. In actual implementation, the L-shaped bracket can be an adjustable round tube bracket, and the height of the L-shaped bracket and the orientation angle of the second scanning terminal can be changed by telescopic parts and rotating parts. The present invention does not limit this, but it can be pointed out that the adjustment of the shooting angle of the second scanning terminal takes into account the influence of external light and the reflection of the shrink film of the cigarette strip. The second scanning terminal does not adopt a vertical shooting angle, but needs to maintain a certain tilt angle.

[0028] Relative conveying direction ( Figure 1 The example is that the gantry 4 is transported from the right side to the left side), the first diffuse reflection photoelectric switch 6 is on the same side as the first scanning terminal 7, and is used to detect the input cigarette box and trigger the first scanning terminal 7 to work; a plurality of second diffuse reflection photoelectric switches 18 are installed in parallel at equal distances on the fixed bracket (the number is determined by the strip box packing mode, and five are shown in the figure, that is, the strip boxes in the cigarette box can be arranged in five columns, with ten strips in each column), which are used to detect the conveying position of the cigarette box and respectively trigger the second scanning terminal 19 to read the QR code on the cigarette strip at the corresponding position; two points can be supplemented here. The first point, the embodiment of the present invention It is suitable for medium-sized cigarette products, and in order to be able to photograph multiple columns of cartons in the cigarette box, the cigarette box input into this system needs to be open; the second point, the spacing between each of the second diffuse reflection photoelectric switches 18 is determined by the spacing between the cartons in the box, that is, the second diffuse reflection photoelectric switch 18 detects multiple different positions of the cigarette box summarized in the conveying process to the left, and when one position is detected, the second scanning terminal 19 is triggered to read the code once and the signal of the second diffuse reflection photoelectric switch 18 that has completed this detection is temporarily invalid, so that the subsequent second diffuse reflection photoelectric switch 18 continues to detect and feedback the cigarette box position without affecting the subsequent second diffuse reflection photoelectric switch 18.

[0029] Continuing from the above, a universal wheel 10 with a brake is installed under the conveyor belt 9. The lockable universal wheel design ensures free movement in any required area of ​​the production workshop and ensures the stability of the position of the system after it is in place.

[0030] In addition, the first scanning terminal 7, the second scanning terminal 19, the first diffuse reflection photoelectric switch 6, and the second diffuse reflection photoelectric switch 18 are respectively electrically connected to the PLC controller 80 installed under the conveyor belt 9; and the first scanning terminal 7 and the second scanning terminal 19 are electrically connected to the industrial computer 1 installed through the fixed bracket 17 (the aforementioned management system can be pre-installed, and wireless network access can be achieved through 5G CPE).

[0031] For the driving mode of the roller 8 on the conveyor belt, please refer to Figure 2 As shown, a bracket 81 and a drive motor 82 are arranged below the conveyor belt 9. The bracket 81 is installed on a support on at least one side of the conveyor belt 9. The drive motor 82 is placed above the bracket 81 and is connected to the outermost roller 8 of the conveyor belt 9 through a transmission chain 83. The drive motor 82 is controlled by the PLC controller 80.

[0032] On the basis of the concept of the above embodiment, two additional points can be explained: First, in order to facilitate the input of the cigarette box onto the conveyor belt, it is considered to drive only the outermost roller 8 of the conveyor belt 9. Therefore, in order to improve the overall carrying effect of the conveyor belt 9, a transmission toothed belt can be provided and connected to the toothed guide wheel configured at one end of each roller 8, so that the outermost roller 8 can drive the rollers 8 on the entire conveyor belt 9 to rotate synchronously. Second, in order to more flexibly and conveniently control the operation of the rollers on the conveyor belt, in other embodiments, the system also includes a conveyor belt speed regulator 11 installed on one side of the conveyor belt 9 and connected to the PLC controller 80 and the drive motor 82 by electrical signals, and the conveyor belt speed regulator 11 is configured with a speed knob 12, a running speed display screen 13 and a roller start and stop switch 14. Of course, it can be further explained here that in other embodiments, the rollers 8 can also be considered to be connected by double-row sprockets, and a tightening block is added under the transmission chain to achieve reliable synchronous operation of multiple rollers 8.

[0033] In order to ensure that the cigarette boxes move stably on the conveyor belt and avoid falling or tilting, it is possible to consider installing a limit bracket 16 through an adjustable bracket 15 on the other side of the conveyor belt 9 relative to the fixed bracket 17. In this way, the cigarette boxes on the conveyor belt can be placed against the limit bracket 16 for smooth and correct transportation.

[0034] Finally, it can be added that further improvements can be made in other embodiments of the present invention, that is, the system can also include a reset button 2 and a status indicator light 3 connected to the industrial computer 1 and mounted on the fixed bracket 17, and the number of the status indicator lights 3 is the same as the number of the second diffuse reflection photoelectric switch 18. A total of five from the indicated position to the right); the status indicator light 3 is used to indicate the QR code parsing association between the strip box and the cigarette box. For example, the QR code on the first row of strip boxes in the box is successfully parsed and associated with the QR code on the cigarette box, and can trigger the corresponding status indicator light 3 to light up. If a status indicator light is not lit during the process, it may indicate a failure in parsing or association. At this time, the staff can trigger the reset button 2 to clarify the current unsuccessful association information, or trigger the system to associate again.

[0035] In summary, the main design concept of the present invention is that it includes a conveyor belt with several rollers, a gantry frame straddling the conveyor belt, a fixed bracket is arranged on the side of the conveyor belt, and a universal wheel with a brake is installed under the conveyor belt; the first scanning terminal is triggered by the first diffuse reflection photoelectric switch, and reads the QR code on the input open cigarette box; the two second scanning terminals are connected to the gantry through an L-shaped bracket, and are triggered by multiple rounds of multiple second diffuse reflection photoelectric switches to read the QR codes on multiple columns of strip boxes in the cigarette box; the first scanning terminal, the second scanning terminal, the first diffuse reflection photoelectric switch, and the second diffuse reflection photoelectric switch are respectively connected to the PLC controller electrical signal; and the first scanning terminal and the second scanning terminal are also connected to the industrial control machine electrical signal. The present invention automatically completes the "bar-item" QR code information association of the cigarette box after the strip box is packed during its transportation process, effectively reducing the labor intensity and significantly saving costs.

[0036] 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.
